FIG. 2 is a front view of an insulating member ir contact with the first fixed contact element;
FIG. 3 is a side view of an insulating member ir contact with a first fixed contact element;

DESCRIPTION OF THE PREFERRED EMBODIMENT A multi-socket assembly board comprises a first fixec contact elements I in the form of contact plates, sec ond fixed contact elements 2 in the form of contac rods and insulating members 3. The plurality of firs contact elements 1 are arranged in a stack, with an insulating member 3 between adjacent first contact element 1.
Each insulating member 3, shown in FIG. 2, is made of insulating plastics material, and has a series of aper tures 4 arranged in two rows, through which aperture: the contact rods 2 are inserted. A series of projection: 5 are provided, each projection 5 being associated witl an aperture 4. The apertures are arranged in two rows the top row 4a being associated with the series of pro jections 5a, and the bottom row 4b being associate: with the bottom row of projections Sb. Each of the pro jections 5a and 5b has a recess, the internal wall 0 which flanks part of the circumference of the corre sponding hole 4a or 5a. As shown in FIG. 2, the recesses of the projections 5a are situated to the left of the corresponding holes 4a, and the recesses of the projections 5b are situated to the right of the corresponding apertures 4b.
The insulating member has a flange 6 (shown in FIG. 3) adapted to come into contact with the adjacent contact plate 1. The entire periphery of the opening of the sockets of the assembly is thus composed of insulating material, as shown in the rear part of FIG. 1. On the other side of the insulating member 3 from the projections 5 there is provided an annular projecting flange 7 associated with each aperture 4. Apertures 8 of the contact plates 1 fit over the outside edges of the annular projecting flanges 7. The contact rods 2 pass through the holes 9 of the insulating member 3 (shown in FIG. 3), and are thus insulated from the contact plates 1.
Each contact plate 1 has a series of projections forming contact 10, each of which is adapted to fit into a corresponding well 11 in the body of the adjacent insulating member 3.
A reversible contact pin 12, shown in FIG. 4, comprises a base member 13, l-i-shaped in cross-section and is made of an electrically insulative material, suitably a plastics material. A non-resilient contact strip lies in a recess on one side of the base member 13 and has two outward protrusions 15 and 16 along the length of its body. A resilient contact strip 17 is attached to the other side of the base member 13 from the non-resilient contact strip and is mechanically and electrically connected thereto, as shown at 14.
When in operation, as shown in H0. 5, a reversible contact pin is inserted into a socket, the resilient contact 17 comes into contact with the associated first contact element and urges the non-resilient contact strip towards the opposite wall of the socket. in the case of the contact pin 12a, the non-resilient contact member strip is prevented from making contact with the rod 20 by reason of the intervening wall of the protrusion 5a, but the nonresilient contact member part 16 is urged into contact with rod 2b, thus making electrical connection between contact elements 10 and 2b.
In the case of the contact pin 12b, the non-resilient contact member part 16 is prevented from making contact with rod 2d, but part 15 is urged into contact with rod 26, thus making electrical connection between contact elements 10 and 2c. Thus the current always flows through the pin in the same direction.
it will be seen that each socket provides the possibil ity of electrical connection between a first fixed contact element and either of two second fixed contact elements, depending on the direction of the pin when inserted.
The multi-socket assembly and associated programme pins just described are susceptible to a number of modifications and adaptations.
The contact strips l5. l6 and 17 of the programme pins may be longitudinally split as shown in FIG. 4A to provide double-contacts. Such contacts are particularly advantageous in low current applications.
The heads of the programme pins shown in the drawing are in the form of short frusto-conical members, but for most applications, it will be convenient to provide a cylindrical grip portion whose length is more nearly equal to that of the part of the pin bearing the contacts. While in the figures, the contact strips on the two sides of each pin have been shown mechanically connected together and thus electrically short-circuited together, in some applications, it may be convenient to split the two sets of contact strips, and possible to connect them together through an electrical component. A particular example of this is the provision of a diode connecting together the two contact strips to provide a diode pin which is advantageous in many applications of such devices as shown in FIG. 4B.
The second contact element rods 2 may be longitudinally divided as shown in FIG. SA on a plane which is perpendicular to the plane of FIG. 5 and parallel to the axis of the programme pins. The two halves are insulated from one another, and in this way each socket is provided with four independent contacts, each formed by one half of a contact rod. The flexibility of an arrangement with the rods divided in this way is apparent.
In the figures, the contacts 10 of the first contact plates 1 are shown as cylindrical projections sweated into the plate. Another arrangement consists in forming these contacts 10 integrally with the plate, for example suitably shaped and arranged projections.
Although not shown in the figures, the front surface of the socket assembly may be covered with a facia provided with an aperture for receiving each programme pin aligned with the sockets of the assembly. Such a facia can carry markings identifying the sockets for facilitating the setting up of a particular interconnection with the programme pins.
The hereinbefore described embodiment provides a multi-socket assembly in which the contact elements have no moving parts, with the consequent advantage that the possible break-down of spring contacts within the assembly is avoided.
An assembly as hereinbefore described can be made to different matrix dimensions, if required, e.g. 10 X 10 sockets, l8 X 32 sockets, etc., or may include more than two layers of first and/or second contact elements, if this is desired.
