Preferably, according to an embodiment of the present invention, the contact portion is configured to elastically displace laterally as it contacts the terminal portion.
Preferably, according to an embodiment of the present invention, the connector includes a receiving groove in which the contact pin is received, and the volume of the receiving groove is set such that the contact pin displaces and / Or deformation of the contact pin.
Preferably, according to an embodiment of the present invention, a step is formed in the lower portion of the interpolation unit such that the DUT board is inserted by a predetermined depth to fix the position.
Preferably, according to an embodiment of the present invention, an engagement portion protruding inwardly is formed on the inner side of the above-mentioned interpolation portion so as to catch at least one portion of the DUT board.
According to the burn-in socket assembly according to the present invention, it is possible to easily remove the DUT board.
In addition, close contact between the contact pin and the terminal portion and fixation and support of the DUT board can be achieved.
Thus, not only a reliable electrical connection between the connector and the DUT board is achieved, but accidental disconnection of the DUT board can be prevented. In addition, it is possible to prevent the connector from being damaged in spite of repetitive disassembly of the DUT board.
Also, unlike the conventional connector structure, since the male connector and the female connector structure can be omitted, a simple structure of the connector structure can be achieved and the production cost can be reduced. In addition, since the refrigerant phenomenon is eliminated due to the SMD type, the reliability of use can be greatly improved.
