Abstract:
Disclosed is a luminaire including a housing for receiving light axially and having at lest one optical surface for emitting light. A lens is mounted in the housing and has a light input portion and a light output portion. A prismatic film is mounted in the housing onto which light output from the output portion of the lens is incident thereon wherein light is reflected by the prismatic film radially outwardly therefrom.
Abstract:
A all-plastic ZIF (zero insertion force) electrical connector offers the advantages of low cost and ease of manufacturing inherent to plastic. According to a first embodiment of the invention, an all-plastic ZIF electrical connector has a bias means connected to a first half of the connector for providing a bias force to force the first half of the connector against a PCB (printed circuit board) or other circuitry inserted between the first half and a second half of the connector. According to a second embodiment of the present invention, the all-plastic ZIF electrical connector is attached to a flexible printed circuit which allows a first half of the ZIF electrical connector to be flexed slightly to increase the space between the contact fingers to accommodate insertion of the PCB without the need to force the PCB between the contact-making fingers of the connector when the PCB is inserted into the connector. In particular the connector is intended to be used on a flexible printed circuit which can be flexed slightly to increase the space between the contact fingers to accommodate insertion of the PCB. After the PCB has been inserted into the space between the electrical contact fingers, fastening means may be attached onto the ends of the electrical connector to maintain the electrical contact between the electrical connector and the PCB. The second embodiment offers the ability to insert the PCB with low or no insertion force, thus avoiding damage to electrical contacts on the PCB while still being able to effect a tight mechanical and electrical contact between the contacts of the connector and the connections on the PCB.
Abstract:
A pad-to-pad connection arrangement between adjacent electrical connectors, such as "bump-to-bump", "bump-to-hollow", or "bump-to-flat" pad arrangements, is achieved. Pads on the surface of an electrical connector may be selectively connected to conductive traces also on the surface of the electrical connector. When two adjacent electrical connectors are joined together in a side-by-side, adjacent relationship, the electrical pads along the side surfaces of the electrical connectors mate, thereby resulting in electrical connections being formed between mated pads of the electrical connectors. According to a preferred embodiment of the present invention, a flexible circuit containing the conductive traces and surface pads is formed about an electrical connector.
Abstract:
Disclosed is an electrical connector of the blade and contact type in which the contact has a tuning fork shape. The tuning fork includes a first tine and a second tine which are spaced apart and are initially parallel to each other. The first and second tines form an elongated slot therebetween. An adjustable tensioner includes an elastic member mounted exterially of one of the tines and a set screw which extends through the elastic member and one of the tines and is engaged with the other of the tines. By adjusting the set screw, the second of the tines is biased in a direction towards the first of the tines and the spacing between the first and second tines is reduced. In this manner, the contact pressure and spacing can be adjusted so that when the blade is inserted into the slot formed by the tines, the frictional resistance can be adjusted. The blade can either be vertically or longitudinally inserted into the slot.
Abstract:
A holder for an electrical or electronic component includes a body formed of electrically non-conductive material having a recess to receive a component such as a fuse. At least two laterally spaced electrically conductive contacts are accommodated by the body. Each contact includes at least one aperture engaging section extending beyond a surface of the body to form a solderless low resistance electrical and mechanical connection with a plated through-hole in a printed circuit board or the like and a terminal section to contact a terminal of a component received by the body.
Abstract:
A stationary pick-up element for use with a rotary connector having a wire rotary element within a housing. The pick-up element comprises an insulated holder for insertion into a slot in the housing, a plurality of conductive fingers incorporated into the holder and disposed so as to contact the rotary element through an exposed portion of the slot, and end connector incorporated into the holder for connection to a plurality of external wires, and a plurality of conductive traces on the insulated holder for connecting the conductive fingers to the end connector.
Abstract:
A mass terminated connector is provided for conducting electrical current. The connector preferably comprises a plurality of U-shaped conductive assemblies and a conductive contact or terminal having a plurality of slots for receiving the conductive assemblies. According to the preferred embodiment, each assembly is manufactured from flat metal stock which is folded into a "U" shape and which includes a series of barbs for penetrating the insulation on the multiple wires of a power cable. The folded metal stock assemblies with connnected wires are received within the associated U-shaped slots in the contact or terminal.
Abstract:
A fiber optic connector backshell surrounds and protects one or more fiber optic pairs which are joined together by fiber optic couplers. The backshell includes a cylindrical body and a sleeve. A clamp seals and secures the body to the outer jacket of a fiber optic cable and an integral frame includes struts which surround access windows and provide a strain relief. The fiber optic pairs and couplers are exposed when said sleeve is removed from the cylindrical body.
Abstract:
A shelf arrangement has an electrical connector which is disposed with one of a plurality of mechanical connection elements of a shelf bracket wherein the connection elements are configured to be received in openings formed in a vertical support bracket; and a contact strip which is disposed with the vertical support bracket and which has electrical connection features that are engageable with the electrical connector to establish an electrical connection therebetween when the mechanical connection elements are inserted into the openings.
Abstract:
A locking cover plate and locking device respectively, control access to a receptacle and inhibit removal of a plug from a receptacle of a power distribution panel having a sequential coupling guard at a row of receptacles. The first locking cover plate rotates to lock and unlock a receptacle by covering the receptacle using a cover plate portion and uncovering the cover plate portion from the receptacle, respectively. The locking device rotates to lock and unlock a plug in the last receptacle by inhibiting removal of the plug from the receptacle using a tab portion and allowing removal of the plug by rotating the tab portion, respectively.
