A plug receptacle electrical connector and a method of manufacturing such a connector. The receptacle connector comprises a moulded insulating cover (1) which receives a moulded insulating base (36) carrying electrical contacts (60) for engaging contacts of a plug connector (100) inserted into a cavity (2) in the cover (1). To enable the connector to be mounted on a circuit board with the contacts (60) connected to circuitry (not shown) on the board, the contacts (60) have lead portions (64) which project beneath the base (36), the bottom of the cover (36) being open to receive the lead portions (64). Rails (48) on the base (36), which engage in grooves (82 and 88) in the cover, being provided on the sides of the base (36) and having thereon latches (50) for engaging shoulders (52A) defined by the grooves (82 and 88). In the manufacture of the connector, the contacts (60) are selectively plated with gold stripes (not shown) for engagement by the contacts of the plug (100).

The device has two parts (12,14) that can be plugged together and that can be coupled by a sliding element (16) fed into one connector part, especially transversely to the plugging direction, and a securing element (24) movable between a starting position and an end position in which it fixes the sliding part in its end position. The securing element is locked in its starting position and is only released for movement to its end position with the connector parts coupled.

An apparatus is provided for use in a device having a battery and one or more power consuming circuit boards that are powered by the battery. The battery connector includes one or more electrical conduits and a housing. Each electrical conduit includes a battery contact, a first circuit board contact, and as second circuit board contacts. The battery contact is for contacting the battery and forming an electrical connection therebetween. The first and second circuit board contacts are for contacting the one or more circuit boards and forming electrical connections therebetween. The housing retains the electrical conduits.

The device has a flexible conductor fixed on one side to a movable contact (16.2) and fixed on another side to a part (11.1) of an electric circuit (11). The conductor comprises of a flexible tube (21), electrically conductive by surface, having low flexural rigidity to bend without being crushed and high torsional rigidity to take a form and a position reproducible in a closed state. An independent claim is also included for a gas insulated electrical substation.

A connector for signal transmission cable, comprises a housing (10) with a central axis (12), a carrier unit (26) accommodated in the housing cavity (14) for an arrangement of signal interface elements (28). In the housing cavity (14) is used a special intermediate ring (16) for retaining the carrier unit (26), where the carrier unit and intermediate ring have inter-operating first axial support devices (40,42,26,48), which in the installed state of the carrier unit, support against the intermediate ring in both directions. The housing and the intermediate ring have second axial support devices (30,32,34,36,38), which in the installed condition of the intermediate ring (16) support against the housing (10) in both directions. An independent claim is included for a tool for unlocking the connector.

A power transmitting apparatus comprises a housing (3) having an opening at its end surface in the longitudinal direction thereof to be closed by a cover member (33), which supports an end of a brake support shaft (60) rotatably supporting a brake shoe (61). A hydraulic cylinder (63) for operation the brake shoe (61) is detachably attached to a side wall of the housing (3). A piston (64) of the hydraulic cylinder (63) contacts with a free end of the brake shoe (61). The cover member (33) also supports ends of a clutch shaft (26) and a PTO shaft (29), while a clutch housing (38) of a PTO clutch (27) is provided on the clutch shaft (26) so as to be braked by the brake shoe (61) in the state of the PTO clutch disengaged, thereby constituting a subassembly. By attaching the cover member (33) to the end surface of the housing (3) so as to close the opening, all the brake support shaft (60), the clutch shaft (26) and the PTO shaft (29) supported by the cover member (33) are installed in the housing (3).

A connector is provided for attachment to a coaxial cable. The connector includes, in one embodiment, a connector body and a locking sleeve. The locking sleeve is configured to be moved between an attached and a detached state. In each such state, the locking sleeve is configured to receive the end of the cable. In one position, the locking sleeve is configured to lock the end of the cable to the connector body.

An electrical appliance housing including a hard plastic housing body defining a switch-actuating aperture. The aperture is sealed with a soft plastic membrane. An actuating button is fastened to a hard plastic base that is bonded to the membrane.

An adapter for communicating over power line is disclosed. An adapter for communicating over power line of the present invention is comprised of a transmitting unit, comprising a power supply including a transformer, a plurality of rectifiers, and a smoother, an oscillator for oscillating a carrier frequency for signal transmission, a switching unit for switching in response to a signal transmitted from a modem, a first coil, positioned between the switching unit and the oscillator, for combining the carrier frequency and data transmitted from the switching unit and magnetizing the combined result; and a first pulse transformer comprising first and second denser electrodes, which are induced electromagnetically by the firs coil and separated mutually and electrically by means of dielectrics or insulators, including first and second lead lines respectively, each connected to the power lines for signal transmission, and a receiving unit comprising a second pulse transformer having a reverse structure to the first pulse transformer a filter for passing the carrier frequency of data among signals output from the second pulse transformer, and a data separating unit for separating transmission data between the filter and the modem.
