Abstract:
A locking system includes a housing that inhibits access to a latching arm of a plug connector and a key that enables a user to depress the latching arm to release the plug connector from a port. Some types of keys define a concave-shaped camming surface that engages the latching arm of the plug connector when the key is inserted into the housing. Other types of keys define a unitary cam member that depresses the latching arm when rotated. Still other types of keys are configured to engage a separate cam member within the housing to rotate the cam member to depress the latching arm.
Abstract:
A memory card socket of the present invention comprises: a hard cam in which a guide groove in the shape of a heart is formed; a pin rod, an end of which is inserted into the guide groove; moving sections having levels, which are formed on the guide groove, so that the end of the pin rod moves along the guide groove, wherein the levels between the moving sections are decreased from at least three levels to one level, and protrusions are formed instead of the decreased number of levels so as to reduce the thickness of the entire hard cam, thereby achieving an ultra-small and ultra-slim memory card and micro SIM card socket.
Abstract:
Die Erfindung betrifft einen Steckverbinder (2) mit einem ersten (1) und einem zweiten Steckerteil (3), welche reversibel koppelbar und separierbar sind, wobei eine Verbindungsvorrichtung ausgebildet ist, welche zumindest ein Federelement (19) aufweist, welches zum Verbinden der Steckerteile (1, 3) mit zumindest einem Federteil (25, 26, 27) in eine Führungskulisse (47) in dem zweiten Steckerteil (3) eingreift, wobei die Führungskulisse (47) und das Federelement (19) so ausgebildet sind, dass bei Überschreiten eines Abreißkraftschwellwerts ein automatisches Trennen der Steckerteile (1, 3) vorgesehen ist. An der Führungskulisse (47) ist eine Abreißerhöhung (50) ausgebildet, die im zusammengesetzten Zustand der Steckerteile (1, 3) von dem Federteil (25, 26, 27) hintergriffen ist, wobei die Abreißerhöhung (50) in Umlaufrichtung um die Längsachse (A) geradlinig ausgebildet ist und sich über ihre Breite in axialer Richtung betrachtet auf gleichem Axialabschnittsniveau erstreckt, so dass bei einem Auftreten einer Zugkraft größer dem Abreißkraftschwellwert auf die Steckerteile (1, 3) zum automatischen Trennen der Steckerteile (1, 3) das Federteil (25, 26, 27) über die Abreißerhöhung (50) ausschließlich in axialer Richtung übergeführt ist. Die Erfindung betrifft auch ein Verfahren zum Verbinden und Trennen von Steckerteilen (1, 3).
Abstract:
The invention relates to a safety device for fixing connector boxes such as those that include a U-shaped sliding element in the connector box, wherein the parallel sides thereof include a series of inclined guides disposed parallel to one another. The upper part on each side of the sliding element (2) has a small piece (9) which is stopped by a tab (8) located on the top part of the connector box (1). Said tab must be pushed to enable passage or withdrawal of the sliding element (2).
Abstract:
An electric connector, comprising a base connector (4) fixed onto a mounting surface (3) and a socket connector (6) extracted from the inserting space (5) of the base connector (4) along the extracting direction (X2) generally orthogonal to the mounting surface (3), wherein, when an electric conductor (7) extending in the direction parallel with the mounting surface (3) (Y) is pulled in the direction parallel with the mounting surface (3) (Y), a tension is converted into a force in the direction of extracting the socket connector (6) (X2) by the activation of the cam surface (24) of the base connector (4) and the cam surface (37) of the socket connector (6), whereby the socket connector (6) can be removed smoothly.
Abstract:
The following invention concerns a plug and socket connector arrangement with a U-shaped plug and socket mating slider (1) which by means of two parallel arms (3) grips one of the complementary parts (12) of the arrangement in order to draw it to the second complementary part (14) of the connector by means of actuating a guide slot (2) and a sliding block arrangement (13). The plug and socket mating slider (1) is led to a guide groove (10) in the connector arrangement, along which are arranged stopping faces (7) against which push the front faces (6) of the arms (3), provided that one of the complementary parts (12) of the connector is not inserted between the plug and socket connector mating slider (1). The said complementary part (12) of the connector spreads apart the arms (3) in the process of its insertion between the said arms (3) in such a way that the front faces (6) of the arms (3) are able to be moved sideways past the stopping faces (7) into their final position.
Abstract:
The present invention is directed to a lever-type electrical connector which has a small lever pivoting range and a large force-amplifying effect. A cam slide (32), which has cam grooves (36a and 36b), is installed inside a front housing (4) of an electrical connector (1) so that the cam slide (32) is free to slide. A lever (6) is linked to the cam slide (32) by slots (34) in the cam slide (32) and projections (20), and lever (6) is attached to the housing (4) by the engagement of pivot members (14a, 14b) and slots (24, 22) so that the lever (6) can slide in a linear manner. When the lever (6) is moved to the right, the cam slide (32) causes a reduction in the distance between the terminals of the connector (1) and the terminals of mating connectors (150 and 170); afterwards, electrical engagement between the respective terminals, which requires a large engaging force, is accomplished by pivoting of the lever (6) so that the connector (1) and connectors (150 and 170) are caused to engage each other.
Abstract:
It is known to use operating slides for connecting multi-contact plugs. The invention relates to an arrangement which ensures that the operating slide is secured in a pre-engagement position, the securing being released in one variant by the insertion of the second plug. A first electric plug (1) has an operating slide (2), where the operating slide is locked in the pre-engagement position. The locking system comprises a spring arm (6) on the first plug with an engagement lug (7). To release the operating slide by moving the spring arm (6), the matching second plug (3) is inserted into the first (1). During this insertion the pin (4) causes the spring arm (6) to move and the operating slide can be moved. The two matching plugs (1, 3) are fitted together by the insertion of the pin (4) into the guide slot (5) and subsequently actuating the operating slide (2). A special advantage is that, with the plugs disconnected, the operating slide can be openly carried in the first plug and that it is so fitted in the latter that it is impossible to lose it.
