Abstract

An electrical connector comprising a block having a matrix of square section recesses. Flat strips of resilient conductive material formed into open loops are arranged so that each loop fits into one of the recesses to form a pair of flexible electrical contacts; each strip interconnecting a row or part of a row of recesses. A cover over the matrix having apertures over the recesses through which electrical components can be inserted to make contact with, and be held by the flexible contacts of the strip of conductive material.

Champion Assistant Examiner-Terrell P. Lewis Attorney-Watson, Cole, Grindle & Watson ABSTRACT: An electrical connector comprising a block having a matrix of square section recesses. Flat strips of resilient BACKGROUND OF THE INVENTION The invention is particularly directed to a connector with which a number of components may be electrically connected without soldering simply by inserting a respective terminal of each component into a corresponding recess.

Accordingly the present invention provides an electrical connector having means defining a plurality of recesses and an electrical conductor interconnecting the recesses, in which the electrical conductor extends into each recess and provides along its length a pair of flexible electrical contacts within each recess into which the conductor extends.

Preferably the conductor is formed from a strip into a series of open loops each one extending when in position into a respective recess, the sides of the loops forming the said pair of flexible electrical contacts. Conveniently the recesses may be of square cross section and a connector block may comprise a matrix of recesses interconnected by a plurality of electrical conductors to form rows of electrically connected recesses. Conveniently there is provided a cover having a plurality of apertures in positions corresponding to the positions of the recesses through which electrical components may extend to make contact with the flexible electrical contacts fonned by the electrical conductor.

LIST OF THE DRAWINGS FIG. 1 is a partially cutaway perspective view of one embodiment of a connector block constructed in accordance with the invention;

FIG. 2 is a perspective view of one loop of an electrical conductor suitable for use with the embodiment of the invention shown in FIG. 1; and

FIG. 3 is a partially cutaway perspective view of a second embodiment of a connector block constructed in accordance with the invention.

DESCRIPTION OF THE DRAWINGS Referring now to FIG. 1 a base 11 is shown supporting a member 12 in which are formed a series of rows of square-section holes 13. The holes 13 are substantially deeper than they are wide and are slightly narrower near the base 11 than they are near the top. A flat strip of flexible electrically conducting material 14 is formed into loops as shown in FIG. 2. When in position in the member 12 the loops extend down into a respective hole. The sides 15 of each loop form a pair of flexible electrical contacts which will retain any electrical component inserted between them. The conductor 14 may extend along the whole length of a row of holes 13 or there may be provided a plurality of conductors each interconnecting a proportion of the holes of a row and having a strip of insulating material inserted into the hole or holes into which the ends of adjacent strips extend in order to isolate them one from another. The assembly of base 11, member 13 and conductors 14 is covered by an apertured cover 16, the apertures 17 being arranged to coincide with the holes in the member 13. Electrical connections may thus be made by pushing the terminals to be connected of a number of components each into one of the apertures 17 connected together by the conductor 14. The apertures 17 which are associated with each other by the conductor 14 are indicated by grooves or paint stripes on the apertured cover 16.

Referring now to FIG. 3 there is shown an alternative construction for the connector block. In this construction a base 18 supports a plurality of interleaving

members

19 and 20 which provide a plurality of square section holes 21. The holes 21 are deeper than they are wide. The members 19 are taller than the members 20 so that two sides of each hole 21 are higher than the other two. This provides a series of recesses in one direction into which the flat strip of flexible conducting material 14 (shown in FIG. 2) can extend. The tops 22 of the taller members 19 thus provide a flat support for an apertured member 23 havin a rtures 24 arranged in group over the square section ho es 1. The sides of the connector block are formed by side members 25 secured in place by adhesive.
