Abstract: A lock device for use with a coaxial cable connection includes an annular inner member and a annular outer sleeve. The inner member has an end portion with threads for engaging the inner member on a male coaxial cable connector part extending from a television or other device. The outer sleeve is inserted over and slid back along a coaxial cable terminating in a female coaxial cable connector part allowing the cable to be connected to the television or other device by the installer's fingers or standard tools such as pliers. The sleeve then is slid forward along the coaxial cable and over the inner member until the outer sleeve covers the inner member and the coaxial cable connection and one of a series of notches on the inside of the sleeve engages a flange on the outside of the inner member.

Latch springs are respectively attached to first and second surfaces of the housing, and respectively have first engagement portions which engage, in a locked state, second engagement portions of a jack connector to be connected with the plug-in connector. An operating member, which cooperates with the latch springs, includes latch releasing portions respectively engaging with the latch springs and disengaging the latch springs from the second engagement portions when the plug-in connector is pulled whereby the plug-in connector is released from the locked state.

Abstract: A female connector housing has male terminals attached thereto and is closed by a cover member, the cover member being allowed to be opened and closed. A male connector housing is inserted into an insertion portion of the female connector housing, so that female terminals are attached to the male terminals. The insertion portion of the female connector housing is opened in such a direction as to face downward when installed. Both the female connector housing and the male connector housing have outlets for holding the electrical cables connected to the male and female terminals on a side that faces downward when installed. Since a connector is opened only at a lower portion thereof, waterdrops falling down from above can in no way enter into the connector.

Abstract: A plurality of kinds of multi-pole sub-connectors are provided with retaining means for retaining them on a frame, and provisionally-retaining projections. If an erroneous insertion is not encountered, the multi-pole sub-connectors are fitted in the frame, and are retained relative thereto, and thus are integrally connected together to provide a first connector. A second connector (i.e., a mating connector) to be connected to this first connector is provided with provisionally-retaining arms each of which forces a corresponding one of the multi-pole sub-connectors from the frame if this corresponding sub-connector is incompletely retained on the frame.

Abstract: A socket (100) for the temporary mounting of an electric part such as an IC package (130) for burn-in testing and the like is shown in which a plurality of contact elements (10, 10') are mounted in the socket each having a stationary part (10a), a spring cantilever arm part (10b) and a contact edge part (10e). The contact elements (10, 10') are mounted so that the leads (130a) of an IC package (130) are each received on a respective contact edge part (10e). When the cover (102) of the socket is closed, wall member (105a) engages the top portion of the leads (130a) and exerts a generally vertical downward force on the contact edges (10e) causing them to be depressed to effect electrical connection between leads (130a) and respective contact elements (10, 10').

Abstract: An electrical connector including a female receptacle and a male spade which cooperate to provide an assembler with sensory indication that electrical connection has been established. The male spade has a body portion which provides a pair of opposed notched recesses. The female receptacle has a metal insert which is integrally molded into a plastic housing and receives the male spade. The plastic housing has a pair of opposed side walls which each provide a deformable arm. The arms have a lower end which includes an inwardly projecting portion that snaps into the notched recess in the spade when the spade is fully inserted into the receptacle. As the spade is inserted into the insert, the inwardly projecting portions slidably engage the spade and cause the arms to be outwardly deflected relative to the housing side wall, thereby providing the assembler with visual and tactile indication that the spade and receptacle are not properly connected.

Abstract: A battery terminal for a terminal post of a battery includes a terminal body formed by a single plate. The terminal body has top and bottom terminal members each continuous to top and bottom tightening members. The top and bottom tightening members are provided with tapered outer surfaces. A tightening tool having upper stage tapered surfaces and lower stage tapered surfaces is place above the tightening members. When the tightening tool is pressed against the tightening members, the upper stage tapered surfaces and the lower stage tapered surfaces press said first and second tapered outer surface to compress said top and bottom terminal members to firmly hold the terminal post.

Abstract: A self-sacrificing latching system for a pair of intermatable electrical connectors, such as a plug and receptacle, which incorporates a mechanism for unlatching same by the application of a maximum predetermined separating force, such as may be the result of an accident to the plug and receptacle. A first electrical connector includes a pair of flexible arms projecting axially therefrom, where the free end includes a bifurcated portion, while the second electrical connector includes a forward ramp surface against which the flexible arms initially ride to effect mating of the connectors. Further, there is a rearward surface slightly angled, i.e. on the order of about 4.degree. to 10.degree., from a base toward the ramp surface, and a metal spring arm mounted within the second electrical connector in close proximity to the base of the rearward surface.

Abstract: The present invention provides an electrical connector used for charging an automobile in which an incomplete connection between a feeding connector half and a receiving connector half is prevented and the work of connecting both connector halves can be easily carried out with a small insertion force.

Abstract: An inline indicating interconnect having a female multi-pin socket connection at a first end and a multi-pin male/male connection and a second, opposed end includes a circuit electrically coupled to and disposed intermediate to the female and male connector ends. The circuit includes at least one light emitting diode (LED) for emitting light when a given electrical condition is satisfied. A generally cylindrical interconnect body comprised of a light-transmissive, moldable material is connected at its respective ends to the female and male connections and overmolded about the circuit components and leads attached thereto so as to encapsulate, seal and provide support for the circuit components and leads while permitting viewing of the emitted light about the entire 360.degree. circumference of the interconnect body. The inline indicating interconnect is particularly adapted for installation in existing cable connections and junctions to provide a visual indication of electrical operation or circuit status.

Abstract: A plug connector is provided that has a latching mechanism for locking to a receptacle connector at the rear of an IC card, wherein the latching mechanism occupies a minimum of space which otherwise could be occupied by additional contacts. The latch mechanism includes a pin-shaped latch (40, FIG. 3) which is rotatable about a latch axis (80) and which has a pair of radial projections (84, 86) at its forward end, so when the projections are inserted into the receptacle housing and turned 90.degree., the projections prevent withdrawal of the latch and therefore prevent withdrawal of the plug connector. An actuator (44) for operating the latch, includes a pair of handles (46, 48) at opposite side edges of the plug connector and a crossbar (104) that connects them and that has a pin (106) which extends into a helical groove (102) at the rear of the latch. The hole (116, FIG.
