Abstract: A cap-shaped retainer 40 has a slit 43 formed therein for insertion of a separation plate, and terminal half-insertion detectors 41 projecting towards terminal fitting insertion chambers 21a of a housing 20. The detectors 41 project individually and are insertable into the lower portions of the respective terminal fitting insertion chambers 21a.

The separation plate is insertable via the slit 43 since the half-insertion detectors 41 are connected beyond the inserted extent thereof.

Abstract: Nestable software license authentication keys connect end-to-end on a circuit board to form an authentication key assembly for internal computer installation or for use as an external assembly connecting to a host system. The circuit board includes at least one plastic housing for one or more authentication keys which define a male connector at one end and a female connector at the opposite end, which connect to a female phone jack(s) electrically connected to the circuit board and attached to the end of a compression spring mounted within each housing. The spring(s) compresses as additional keys are connected end-to-end on the board and the spring biases the keys against the end of the circuit board. The authentication key assemblies may utilize a variety of circuit boards with a variety of connectors, and the external assembly is encased in the plastic housing for use with portable and Apple-type computers.

Abstract: An object of the invention is to quickly supply inexpensive large current terminals without entailing complicated metal-working process and labor. Further, another object thereof is to provide methods of metal-working such terminals. A large current male terminal is constructed by forming a hollow cylindrical electric contact part on one end of a conductive pipe, a hollow cylindrical wire crimping part on the other end thereof, and a collar between the electric contact part and the wire crimping part. The electric contact part has a substantially conical nose and is formed by squeezing one end of the conductive pipe in such a manner that the diameter of the one end is gradually reduced frontward. The wire crimping part has such an inner diameter as to allow a wire to be inserted thereinto. The collar has a diameter larger than the other parts.

Similar lengths of rear modules are provided.

Abstract: An RJ-11 jack, or plug, is described that is self-locking and has a self-ejecting feature. In particular, an RJ-11 jack is constructed with a tang on the rear lower portion of the RJ-11 jack in such a way that the tang is coupled to a locking tab of the RJ-11 jack. When inserted into an RJ-11 receptacle, or housing, the tang is compressed as a result of contact with an inside wall of the RJ-11 receptacle. The locking tab of the RJ-11 jack locks the RJ-11 jack into position with the tang compressed. The RJ-11 jack includes a tool access opening such that a tool, like a small screwdriver, can be inserted to press on a release tab, which is connected to the locking tab. When pressed, the applied force pushes up on the release tab, thereby moving up the locking tab and releasing the RJ-11 jack. The resultant decompression of the tang causes the RJ-11 jack to eject.

The support plate (2) is comprised of several layers (20, 21, 22), and the contact elements (4) are set into bores (3) and are removably held and axially locked into place in the bores (3) between two layers (20, 22) by a bead (51) formed on the contact elements, preferably in a vacuum-tight manner.

Abstract: An HF plug connection system with low transfer resistance even in the high frequencies in the range of 10.sup.8 Hz, comprising a standardised socket insert and a corresponding plug as plug connector parts. In this system, an earthed screening (10) runs from cable to cable (16) through both parts of the plug connector. It is connected over a large area to the metal braid (36) of the HF cable (16) of one and/or the other plug connector part, with large surface area throughout in relation to the cross-section, and at least one flexible area (26, 28) outside the insulation sheath (34), and the screening is passed to large contact areas (46) for the complementary part of the plug connector. Thus the cable end can be adjusted to any required angle, which allows a shorter installation length.

Abstract: A coupling is described for conducting electrical signals between two members which are movably mounted to each other. The coupling uses a piece of compressed electrically conductive elastomer material to maintain physical and electrical contact between the two members. The coupling is well adapted for conveying low current analog or digital control signals. In a preferred form the coupling is a rotary coupling which has a drum mounted for rotation in a cavity in a housing. The outer surface of the drum and the inner surface of the cavity each have a number of circumferential electrically conductive rings aligned in pairs. A ring of electrically conductive elastomer material is compressed between each pair of rings. The coupling can be advantageously combined with a rotary coupling for hydraulic fluid. In the combined electric-hydraulic rotary coupling the electric portion of the coupling is flushed with hydraulic fluid.
