Abstract

A multiple-pin terminal adapter comprising a substrate and a multiplicity of electrical contact pins extending from above and below the substrate for connection with printed circuit boards. A first group of contact pins extend downwardly for connection with the underlying printed circuit board, while a second group of contact pins extend upwardly out of axial alignment with the first group to assume a generally meander or otherwise random formation whereby adjacent contact pins in the second group are spaced a sufficient distance apart from one another to facilitate access for solder connection. A relay socket means is also provided for use in combination with the terminal adapter to provide easy access for connection to printed circuit boards packed with high density electrical components.

Claims

1. A multiple-pin terminal adapter for electrical connection to printed circuit boards, the terminal adapter comprising:

a generally rectangular substrate made of insulating material;

a first group of a multiplicity of contact pins extending downwardly from said substrate; and

a second group of a multiplicity of contact pins extending upwardly from said substrate, said first and second groups of contact pins being equal in number to each other and connected electrically with each other, said first group of contact pins being disposed linearly in closely spaced relation for electrical connection to corresponding leads on a flat-packaged integrated circuit, said first group of contact pins having substantially the same shape and geometry as the integrated circuit to be electrically connected thereto, and said second group of contact pins being disposed at a larger pin-to-pin spacing than and said first group of contact pins, and the contact pins of said second group being disposed out of axial alignment with the contact pins of said first group for electrical connection to leading wires or external components.

2. A terminal adapter according to claim 1;

wherein said second group of contact pins is oriented in a meandering formation via guide slits provided in said substrate.

3. In combination:

(a) a multiple-pin terminal adapter for electrical connection to printed circuit boards, the terminal adapter comprising a generally rectangular substrate made of insulating material, a first group of a multiplicity of contact pins extending downwardly from said substrate, and a second group of a multiplicity of contact pins extending upwardly from said substrate, said first and second groups of contact pins being equal in number to each other and connected electrically with each other, said first group of contact pins being disposed linearly in closely spaced relation for electrical connection to corresponding leads on a flat-packaged integrated circuit, said first group of contact pins having substantially the same shape and geometry as the integrated circuit to be electrically connected thereto, and said second group of contact pins being disposed at a larger pin-to-pin spacing than and said first group of contact pins, and the contact pins of said second group being disposed out of axial alignment with the contact pins of said first group for electrical connection to leading wires or external components; and

(b) a relay socket means for use with the terminal adapter, the socket means comprising a substrate member made of insulating material and being similar in shape to and coextensive with the substrate of the terminal adapter, a multiplicity of contact pins projecting upwardly from said substrate member and oriented equal in number and geometry to the second group of contact pins on the terminal adapter, and a plurality of jacks extending downwardly from said substrate member and positioned equal in number and formation to and in registration with the multiplicity of contact pins on said substrate member.

4. The combination according to claim 3;

wherein the socket means has a retaining post at each of its corners, the retaining posts extending upwardly, or both downwardly and upwardly, and dimensioned to make fitting engagement with guide holes provided at corners in the terminal adapter, each of said retaining posts having a larger length than the second group of contact pins on the terminal adapter.
