A socket for receiving a line of contact pins is formed of modules connected together. The modules have three, four or five pin receiving openings and are joined to one another by dovetail connectors to form an elongated body having the desired number of pin receiving openings. Contacts are provided in the pin receiving openings to electrically connect with the pins. The modules have a ledge on which rests a work surface.

The present invention generally provides a case for a printed circuit board which forms a single in-line pin configuration from an edge connected circuit board. The case includes a frame enclosing the edges of the circuit board and a base at a mounting plane side of the frame. Connector pins affixed to the edge connectors of a printed circuit board are secured to the printed circuit board and extend from the base. A tab extending generally parallel to the frame from an edge of the base provides a smooth vacuum pick up engagement surface for handling and placement of the present case.

Case for circuit board

The present invention provides a housing for an auxiliary circuit to be connected to a main circuit. The housing includes a heat tab for conducting the heat away from the auxiliary circuit components and an insulating case which is molded together with the heat tab to interlock the heat tab to the case. The case is molded around a chamfered edge of the heat tab. The insulating case includes a back and two sides extending from the back to define an area which contains the auxiliary circuit components. The heat tab is molded into the back and faces the component area so heat generated from the components can be spread to the main circuit by the heat tab. Openings may be provided through the back of the insulating case. The heat tab and legs on the sides of the housing are used to mount the power supply to a circuit board.

A holder for a toroid coil has a planar top surface for engagement by a vacuum pickup and four side walls extending to a mounting plane and defining a toroid containing space therewithin. Wire wrap posts extend from one side of the holder and wire pass through openings enable the wire to hold the coil in place while permitting the solder connection location to lie outside the holder in view for inspection.
