An electrical connector for securing a cable having a insulation and a cover engaged on the insulation, the electrical connector includes a clamping member , a spring, a cone, another clamping member and a pusher engaged in a cylindrical body. The clamping members each includes a number of clamping blades for clamping the insulation and the cover in place. The pusher includes one end for expanding the clamping blades of one of the clamping members and may push the cone to expand the clamping bla...

In an electrical contact, upper end portions of a pair of contact piece portions formed by blanking are bent along respective inclined folding lines into a generally inverted L-shape to form a pair of lead holding portions, so that a lead receiving slot is formed between the pair of lead holding portions, the two inclined folding lines being disposed respectively on blanked-out surfaces of the two contact piece portions. With this construction, the blanking is effected in such a manner that the ...

An electrical coupling for use in an appliance such as a kettle or hot water jug comprises an inlet in the appliance having a standard pin configuration, but a non-standard profile to prevent a standard connector being inserted therein. A connector for engagement therewith has a standard socket configuration but a non-standard shape to prevent it being inserted in a standard inlet. The polarity of the line and neutral terminals within the connector is reversed with respect to the standard config...

An insulation displacement contact comprises first and second contact portions each of which comprises a cantilevered split beam. The upper split beam, which receives insulated wires, comprises a pair of tynes which are folded about the axis of a slot separating the tynes such that the internal angle between the tynes is approximately 90.degree.. The width of the times is larger than that of prior art devices resulting in increased stiffness and the length of the tynes is sufficiently long to re...

An electrical connector assembly according to the current invention comprises a receptacle and a right angle header for connecting two or more printed circuit boards. A composite action beam is located in the receptacle and has a movable end and a fixed end. During an initial phase of the pin insertion cycle, the movable end of the composite action beam deflects so as to minimize the force necessary to insert the pin into the connector housing. During an intermediate phase of the insertion cycle...

A device for forming an electrical connection between a plurality of elongate electrical conductors comprises an electrically insulating sleeve, and contained within the sleeve a resiliently deformable tapering coil and a quantity of fusible polymeric material, the device being arranged so that the elongate electrical conductors may be connected by twisting them into the coil so that at least part of the coil is deformed and heating the device so that at least some of the fusible polymeric mater...

An electrical connector with a terminal locking member for doubly locking terminals in terminal accommodating cavities in which terminals are smoothly inserted into terminal accommodating cavities in a connector housing and the terminals are doubly locked with certainty. The electrical connector comprises: a housing; terminal accommodating cavities in the housing; a terminal locking member slidably attached to the housing in a preliminarily locked state and a fully locked state; terminal locking...

This electrical switch (1) consists of a flat spring, profiled in order to provide both a contact function and a spring function; the flat spring (1) includes a first leg (2) which can be deformed by bearing on a fixed pivot pin (3) of a support (4), and a second leg (5), which can move at the same time as the first leg deforms and whose end (5a) can assume either of two positions for contacting pins (14,15) of an electrical circuit. The switch according to the invention is less bulky than the u...

The four corners of the pressure section (20) of the contact (10) punched out of a metal sheet are rounded off to form an oval surface (22). The lower portion (38) of the contact mounting opening (32) of the housing (30) is made of the same configuration as the pressure section (20). Since the dimensions of cross section of the lower portion (38) are made smaller than the corresponding dimensions of the pressure section (20), a tight joining is formed around the pressure section (20).

A single pole electrical switch of relatively thin overall dimension has a rocker provided on an off center axis in the circuit breaker housing, which rocker is adapted to slide a moveable contact across the upper ends of the fixed contacts to achieve opening and closing of these contacts. The moveable contact in the off position is spaced from one of the end walls of the switch case housing to allow provision for a third fixed terminal in a stepped portion of the bottom wall. The upper end of t...
