Electric part testing apparatus with movable adapter

An electronic part testing apparatus for testing a connectability of a wiring pattern of an electronic part having a plurality of terminals, said apparatus comprising:

• a testing member including an electrical connection pattern, said electrical connection pattern being electrically connected to said terminals of the electronic part for the test;
• an adapter positioned between the electronic part and the testing member;
• said adapter comprising electrical connections between said terminals and said electrical connection pattern when the electronic part is mounted on the adapter for the test;
• said terminals including a plurality of first terminals and a plurality of second terminals;
• said adapter including holes corresponding to said first and second terminals and first and second connecting members accommodated in said holes, respectively, said first and second connecting members having terminal contact surfaces positioned within said holes;
• and
• said terminal contact surfaces of said first connecting members being located at a higher position than said terminal contact surfaces of said second connecting members;
• said adapter comprising a body, including the holes, with said first connecting members and said second connecting members being arranged in said holes, wherein said first connecting members and said second connecting members are movable with said body and also movable relative to said body.

• said adapter including first connecting members corresponding to the first terminals and second connecting members corresponding to the second terminals;
• and
• said testing member including through-holes corresponding to the first and second connecting members, respectively, including on inner wall surfaces conductive layers connected to the electrical connection pattern, and testing member connecting members disposed within the through-holes to contact the conductive layers,
• whereby the testing member connecting members contact the first and second connecting members, respectively, to establish the electrical connection.

An electric connecting member comprising:

• a first contact portion for contacting a first external contact portion;
• a second contact portion for contacting a second external contact portion;
• an elastic member disposed between the first contact portion and the second contact portion;
• and
• a conductive straight pipe accommodating therein the first contact portion, the second contact portion and the elastic member, whereby the first contact portion and the second contact portion are electrically connected;
• wherein
• the first contact portion, the elastic member, and the second contact portion are all freely movable through the conductive straight pipe,
• the conductive straight pipe is secured between two members, and
• the first contact portion and the second contact portion each includes a respective enlarged side portion contacting respective ones of said members.
