摘要： A disc designed to be placed between a light bulb and the bottom of a mating Edison socket into which the light bulb is screwed is capable of attenuating power by rectifying alternating current to the bulb in one mode and in another mode is capable of passing full current to the bulb. Thus, by lightly screwing the bulb into the socket, the bulb glows dimly, its power being supplied through the rectifier. When the bulb is more tightly screwed into the socket, the disc is compressed and the device applies full power to the bulb. The switching is accomplished by offsetting the rectifier and allowing pressure exerted between the light bulb's center contact and the bottom of the socket to operate a switching mechanism, preferably located at the center of the disc. The switching mechanism shunts the rectifier in the full-power mode of operation.

摘要： An electrical socket and associated circuitry is provided wherein current can flow to the socket only when a load device is in the socket and a normally open, momentary "make" switch is closed. The circuitry includes a relay for actuating a switch in parallel with the momentary make switch, which relay is energized upon closure of the momentary make switch and remains energized so that current will continue to flow to the socket until a normally closed, momentary "break" switch is opened. Current cannot flow through the socket with the load device removed even if one should touch the socket except in the unlikely event the make switch is closed.Several embodiments are disclosed wherein no current can flow through the socket unless at least three socket parts are engaged. In one form of socket, the socket base contact is divided into two parts, both of which must be engaged in order for the relay to remain energized. In another form the socket shell contact is divided into two parts and again both parts must be engaged for the relay to remain energized. Other sockets are illustrated wherein the presence of a load device is sensed by switch means which may include the socket base contact.Circuits for use with polarized plugs are disclosed and a form of circuit for use with an unpolarized plug is also disclosed. Further, a circuit utilizing a rectifier and a low voltage relay is also disclosed wherein the make and break switches are in low power lines.

摘要： The present invention relates to a safety device in electrical connection devices, especially lamp-holders, comprising a number of contact parts designed to rest against an object arranged to be connected to the connection device, for example a light bulb socket, and a number of elements arranged to be connected to the electric leads of a cable, whereby the contact parts are at a distance from the respective connector elements and are arranged by means of being pushed in by a spring function to achieve contact with these during connection of said object to the device. According to the invention the device is provided with at least one insulating element, forced to be between the contact parts and the respective connector elements and thereby prevent contact between these when said object is removed from the connection device, and simultaneously arranged to be moved by means of the object during its connection to a position in which the contact parts and the respective connector elements are free from the insulating element to be pressed against each other by means of the object by its connection.SUMMARY OF THE INVENTIONThe present invention relates to a safety device in electrical connection devices, especially lamp-holders, comprising a number of contact parts designed to rest against an object arranged to be connected to the connection device, for example a light bulb socket, and a number of elements arranged to be connected to the electric leads of a cable, whereby the contact parts are at a distance from the respective connector elements and are arranged by means of being pushed in by a spring function to achieve contact with these during connection of said object to the device.Safety devices intended to prevent involuntary contact with current carrying parts are common in for example wall sockets. Connection devices of this type are however relatively easy to protect as the live parts are accessible only through small openings which can be provided with flaps or shutters or similar. In the case of contact fittings with larger openings it has however not proved possible to achieve practical, automatic safe-guards against involuntary contact. An example of the type of contact fitting with a great risk of involuntary contact is that of normal lamp-sockets. As long as a lamp is screwed in the risk of involuntary contact is generally small, whereas if on the other hand there is no lamp screwed into the lamp-socket the live parts are accessible through a wide opening.The object of the present invention is to achieve a safety device that creates a safe-guard against involuntary contact even in the case of such connection devices which are showing a large opening, especially lamp-holders.The purpose of the invention is achieved by constructing the safety device that at least one insulating element is forced to be between the contact parts and the respective connector elements and thereby prevent contact between these when the said object is removed from the connection device and simultaneously arranged to be moved by means of the object during its connection to a position in which the contact parts and the respective connector elements are free from the insulating element to be pressed against each other by means of the object by its connection.BRIEF DESCRIPTION OF THE DRAWINGIn the accompanying drawings three embodiments of the invention are shown, withFIGS. 1 and 2 showing a lamp-holder in two central elevations perpendicular to each other,FIG. 3 shows a bottom plate in the lamp-socket in front view elevation andFIG. 4 shows a detail in the lamp-socket in perspective,while FIGS. 5 and 6 demonstrate the function of the embodiment in FIGS. 1-4.FIGS. 7, 8 show the second embodiment in two positions,FIGS. 9, 10 show a bottom plate of the third embodiment in section and front view elevation respectively.DETAILED DESCRIPTION OF THE INVENTIONIn accordance with the figures the lamp-holder shows a casing 1 with an opening 2 and a thread 3 for screwing in the socket of a light bulb. Inside the thread 3 there are two spring contact sheet metal shields, one side shield 4 and one central shield 5, which make contact with the current collecting portion of the bulb when it is screwed in. Right opposite the opening 2 there is a hole 6 for a flex that can be joined to connector clips 7. In the usual type of lampholders the contact shields are connected directly to the connector clips, possibly via a switch. In the case of the lamp-holder according to the invention however the contact shields 4, 5 are not connected directly to the connector clips 7, but instead only make contact after overcoming the spring resistance built in to the shields and pressed with sections 8 against sections 9 which are in direct contact with the connector clips 7. Such a contact is however prevented by a bridge 10 made of insulating material forced by means of the tension in a spring section to take up a position between the contact parts 8 and 9.When there is no bulb screwed into the lamp-socket the contact shields 4 and 5 thus are forced to take up a position with their contact parts 8 at a distance from the contact parts 9 of the connector clips 7, and they are thus already out of contact with the live leads. In addition the insulating bridge 10 is between the contact parts 8 and 9 and is retained in this intermediate position by the spring section 11. This prevents contact between the contact parts 8 and 9 even if one of the contact shields 4, 5 were subjected to pressure.If however a light bulb is screwed with its socket down in the thread 3, the edge of the socket will first meet the part 11, thereby pushing the bridge 10 across to the right in FIG. 2; with this the edge of the bridge is freed from its position between the side shield 4 and its connector clip. Simultaneously a hole in the bridge 10 will be right opposite the central contact 5. As the bulb is screwed further in, its respective current collectors will press the contact shields 4, 5 towards their connector clips 7, and in this position the bridge 10 is no hindrance, instead at the lowest position the bulb socket has ensured contact between the contact parts 8 and 9, and the bulb obtains contact with the live lead.When the bulb is screwed out, the parts return to their starting positions. In order to make involuntary contact with any live parts in a lamp-holder without a bulb screwed in, one would thus first have to push the bridge 10 to its non-active position and then press down the contact shield opposite a connector clip 7 that is connected to an electric conductor. For this to take place is all but beyond the realms of probability.FIGS. 5, 6 show how the bridge 10 takes up its various positions in relation to the contact parts 8, 9 in safeguarded and contact position respectively.The basic idea of the invention is thus that the respective parts that are to conduct current to the connecting part, in this case the light bulb, are not directly connected to the current carrying lead but instead achieve this connection only by being pushed in against a spring force, which in turn is prevented by means of a device designed to be pushed aside by the connecting part. This principle can of course be applied to other electrical contact devices than lamp-holders and can also be applied irrespective of the number of contacting terminals.As to design there is a wide scope of variation, especially in the matter of the part that is to prevent the contact shields from being pushed in. In the example cited a sliding bridge is used, but in accordance with FIGS. 7 and 8 a hinged bridge 14, mounted on a axis 15, can be used. The bridge 14 is affected by a spring not shown and is forced to take up the position shown in FIG. 7, covering the contact parts 9. When a bulb is screwed in the edge of its socket meets a projecting device 16 turning the bridge 14 on the axis 15 so that the contact parts 9 are bared and the current collectors can be pressed down against the live contact parts. If instead the projecting device is placed at the end 17 of the bridge 14 and is allowed to drag against the edge of the bulb socket, instead of compressive force the friction so arising will be used to swing the bridge. Thus the bridge through this friction will be turned clockwise when the bulb is screwed in thereby exposing the contact parts 9, and anti-clockwise when the bulb is screwed out again covering the contact parts 9. The spring mentioned thus only needs to be contrived to keep the contact bridge in a covering position, when there is no bulb in the lamp-holder, while the spring does not need to be arranged to return the bridge to a covering position. This ensures an even greater guarantee that the bridge returns to its position even if there should be deformations or burns on the contact parts.The bottom plate of the third embodiment of the lamp-holder is shown in FIGS. 9 and 10. This bottom plate is comparable to the bottom plate 4, 5, 7, 8, 9 of the embodiment according to FIGS. 1 and 2. The bottom plate comprises a body 18 of insulating material on which central contact shields 19 and a side contact shield 20 are attached by means of a rivet 21. Between the parts 19, 20 is placed an intermediate plate 22 of insulating material, so that as evident from FIG. 9 the two shields are not electrically connected to each other. According to FIG. 10 the side contact shield 20 is provided with two legs, one of which has a part 23 provided to be pressed against a side contact 24 and obtain electrical connection with the same. In the same way the central shield 19 has a part 25 provided to be pressed against a contact 26. The two contacts 24 and 26 are provided with screw clips 27 intended to be connected to the conductors of the cable by means of which the lamp-holder has to be connected to the source of current.In the same way as by the first and second embodiments the contact parts 23 and 25 of the contact shields 20, 19 respectively, are separated from their respective contacts 24, 26 by means of a plate 28 of insulating material. The plate 28 is pivotable round an extension 29 of the body 18 forming a shaft for the plate 28. The second leg of the side shield 20 (pointing downwards in FIG. 10) is provided with a pin 30 in engagement with the plate 28 by means of a hole 31 in the latter. At the upper boarder of the side shield legs there are wings 32 and 33 provided to rest against the circumference of the lamp-socket when it will be screwed down into the lamp-holder.The central shield 19 is of resilient conducting material for example bronze and it is formed to be in the position shown in FIG. 9 with the contact part 25 a certain distance from the contact 26. The first leg of the side shield 20 is of the same material and formed in the same way so that the portion 23 is positioned a certain distance from the contact 24. The second leg of the side shield 20 is bent inwards as shown in FIG. 10 and forces the plate 28 by means of the pin 30 and the hole 31 to the position shown in FIG. 10 placed between the parts 23, 25 and their contacts 24, 26.If the bottom plate according to FIGS. 9, 10 is mounted in a lamp-holder of the form shown in FIGS. 1, 2 and the lamp is screwed down into the lamp-holder, the rounded border of the metal socket on which the thread of the lamp is formed will be pressed against the wings 32 and 33 of the legs of the side shield 20. Thereby the leg with the wing 33 will be pressed outwards as the sloping surface of the wing 33 slides against rounded border of the lamp-socket. As the pin 30 moves outwards the plate 28 will pivot clockwise (in FIG. 10) and the portion of the same placed between the part 23 and the contact 24 will move from this position and at the same time a hole 34 in the plate 28 will be positioned in line with the part 25 of the central shield 19 and its contact 26. The parts and their contacts are consequently free to meet each other when the first leg of the side shield 20 and the central shield 19 are pressed down by the lamp-socket when screwed further down into the lamp-holder. Thereby the shields are connected to the conductors attached to the clips 27.

摘要： An electrical connector, for example a lampholder comprises an on/off switch mechanism including a push bar. The connector further comprises a locking arrangement including an interlock member which extends to the pushbar and moves into and out of cooperation with an aperture in the pushbar. When a cooperating device, for example a lamp, is inserted into the connector the interlock member moves axially into the lampholder to a position at which the pushbar is free to move between "on" and "off" positions. When no cooperating device is connected, the interlock member prevents movement of the pushbar. The pushbar and the interlock member include respective inclined surfaces arranged such that the pushbar will be moved to the "off" position when a cooperating device is removed from the connector.
