Abstract
The test socket according to the present disclosure is configured to bring terminals of a device under test into contact with electrode pads of a test board, that generates a test signal, to electrically connect the device under test and the tester, the contact part-module configured to allow the contact part to be in an aligned state is separatably coupled to an upper side of the second lower housing of the test socket, so it is possible to easily replace the contact part with new one without separating the test socket from the test board.
Claims10
A test socket configured to bring terminals of a device under test into contact with electrode pads of a test board, which generates a test signal, to perform an electrical test for the device under test, comprising:
- a first upper housing having first upper housing holes, which are formed therein and correspond to the terminals of the device under test, respectively;
- a first lower housing having first lower housing holes, which are formed therein and correspond to the first upper housing holes, respectively;
- a second lower housing having second lower housing holes, which are formed therein and correspond to the first lower housing holes, respectively;
- and
- a plurality of socket pins, each of which including an elastic part in which a lower plunger may be elastically supported in a cylindrical barrel body to come into contact with the electrode pad, and a contact part formed as separate part from the elastic part and divided into a first portion capable of coming into contact with the terminal of the device under test and a second portion coming into contact with the elastic part and having a diameter greater than that of the first portion;
- wherein the elastic part is disposed and supported in the second lower housing hole, and the contact part is disposed and supported in a contact part-module formed by coupling the first lower housing to a lower side of the first upper housing.
