An electrical cable comprises one or more insulated elongate electrical conductors (1,2), a metal electrical shield 5 surrounding the conductors and a pull-thread 7 that extends along the cable under the shield so that the shield can be cut longitudinally by pulling the thread. The cable can be stripped of shield and jacket simply by pulling the thread and then tearing the end of the shield and jacket off. If desired a second conventional pull thread may be located between the shield and jacket ...

An improved female connector element for a pin and socket electrical connector includes at least four flexible fingers or "cantilever beams" forming a cylindrical socket for the pin of a male connector. A cylindrical sleeve surrounds the fingers and extends beyond their free ends to form an inwardly extending annular guide lip which defines the inlet opening for the pin. The lip both guides the pin properly into the socket and limits the size of the pin that may be inserted, thereby reducing pot...

An electrical connector, particularly an insulation-displacement connector of split-beam design, comprising a metal that at constant temperature has an elasticity of at least 0.8%. This allows the connector to be used with conductors over a large diameter range.

An electrical switch (10) or fused switch for electrical distribution systems has a housing (12, 14); first and second spaced apart straps (16, 18), coupled to the housing; and a pair of opposed blades (22, 24) pivotally coupled to the first strap and straddling both straps. The blades (22, 24) are capable of relative pivotal movement from an open position spaced from the second strap to a closed position in contact therewith. A blade extension (30) is coupled to the blades between the straps. T...

An electrical connector assembly has a socket body which is mounted on a printed board and is adapted for receiving a complementary plug with contacts. The socket body has a bottom and a pair of opposed side walls defining therebetween a cavity for receiving the plug. The socket body carries a plurality of connector contacts, each of which is bent to define an inner leg and an outer leg both extending from a bent. The inner leg extends along an inner surface of the side wall within the cavity fo...

An elongated electrical lead has a first part of a hard and brittle arc quenching metal integrally joined to an easily bendable second part of a ductile metal. The lead is used in a thermal cutoff with the first part being inside of the thermal cutoff housing and having an end portion defining an electrical contact. The second part of the lead extends outwardly from the thermal cutoff for connecting same in an electrical circuit.

The receptacle contact (10) includes a box-shaped contact section (12) with its upper wall folded over to provide protrusions (36) to abut against the tip of a resilient arm (48). Such receptacle contacts (10) are inserted into contact receiving cavities (42) in the connector housing (44). A double-lock member (150) may be used for double locking the contacts.

An electrical connector which has improved durability is provided. The housing of the connector has a first surface mounted on a mother board and a second surface on which a daughter board is mounted and which is disposed opposed to the first surface. On both ends of the first surface mounting legs are provided for receiving an edge of the mother board. On both ends of the second surface latch members for holding the daughter board and stoppers slightly spaced from the latch members are provided...

A two piece type electrical connector is provided which is matingly connect together boards in a designated correct polarity relation. A pair of first latch members L-shaped in cross-section are projected one at each end of a mother board-side housing and each have a ridge-like friction latch. A pair of second latch members L-shaped in cross-section are projected one at each end of a daughter board-side housing. One surface side of the second latch member has a projection inserted into the guide...

A pair of plug-side engagement members are mounted one at each end of a plug connector attached to a mother board. A pair of receptacle-side elastic members are provided on a daughter board attached to a receptacle connector, os that the receptacle-side elastic members correspond to the plug-side engagement members. With the plug-side engagement members connected to the receptacle-side members, the former is elastically engaged to the latter so that a mechanical insertion force is exerted on the...
