Abstract: A triaxial contact assembly for terminating a screened twisted pair of wires comprises three contact members (12,14,16) and a ferrule (18). The inner contact (12) is of conventional construction but the intermediate contact member (14) consists of an intermediate contact (20) to which are secured the inner insulator (34) and a spacer member (40). The outer insulator (54) is fixed to the outer contact (52). The number of separate components required to be assembled by the operator is thus reduced and assembly made quicker and easier.

Abstract: A shielded electrical connector includes a housing arranged to receive a shielded cable, a connector for connecting the cable shield to the connector housing, a connector element located in the housing with contacts connected to tracks on a printed circuit board within the housing, a ground plane spaced from the printed circuit board and electrically connected to the connector housing and a plurality of surge arrestors located between respective tracks on the printed circuit board and the ground plane. A resiliently flexible member may be located between the connector housing and the ground plane for making an electrical connection between the housing and the ground plane.

Abstract: An electrical connection housing, especially for undercarpet cable systems, including a fixed member (50) which is to be secured to a flat surface and which has an outer side face for receiving a module member (220, 222, 224). The module member has an inner face which conforms to the outer side face of the fixed member (50) and engagement extensions (230) which extend under the outer side face of the fixed member (50) for retention between the fixed member and the flat surface. Recesses (232) are provided in the bottom of a shroud (200) to receive T-shaped extensions (230). The module member may include telephone outlets, data outlets or power spurs.

Abstract: A push-on pull-off connector member 30 for coupling to a standard bayonet receptacle 10 has three equi-spaced circumferential slots 36 for receiving the bayonet pins 20 of the receptacle 10. Spring rings 40 in circular recesses 38 opening into the slots 36 from each side retain the pins 20. The recesses 38 are easily formed, for example, by milling. The coupled connector resists a weak uncoupling force but separates under a strong force, and can provide a snatch-disconnect facility.In alternative embodiments, each slot 36 has a single circular ring (FIG. 6), two spring rings are formed at each end of a single member (FIG. 4), the rings have inwardly-directed tangs for ease of fitting and removal (FIG. 5), or the spring rings are parts of question-mark shaped members (FIG. 7).

Abstract: The invention relates to screw-coupled electrical connectors. It is known to provide screw-coupled electrical connectors with means for providing an indication of the fact that the two parts are approaching or have reached the fully mated condition and for resisting subsequent rotation of the coupling sleeve in the uncoupling direction. However, this has been accomplished only with complex and expensive mechanisms such as movable balls mounted in a flange on the first connector part and a series of holes in a flange on the coupling sleeve.
