Description

Connector {Connector}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector, and more particularly, to a connector that prevents damages and data errors of a connection part mounted on a connector, and which is firmly connected between the connectors and is dimensionally stable.

In order for the connector and the connecting part mounted on the connector to electrically contact with each other securely, the electrical terminal provided on the contact pin and the connecting part provided on the connector must be pressed. If the pressing force is strong, the electrical contact property is high, but the frictional force becomes large, so that it is difficult to insert or separate the connecting component into the connector. Particularly, when a connector is provided with a plurality of pins, or when a connection part is to be simultaneously inserted into a plurality of connectors, a large force is required to insert the connection part. In order to solve such a problem, a so-called zero insertion force connector (ZIF) has been proposed in which a contact pin is pressed against a connecting part after insertion of a connecting part without requiring a force when inserting the connecting part have.

A semiconductor test apparatus used for testing a minute semiconductor requires high reliability in operation. In order to test semiconductors at high speed and reliability, the connectors used in the test equipment must be in contact with the connecting parts.

[ The connector 50 into which the connecting part 40 is inserted includes a contact pin 70 that contacts the electrical terminal 48 of the connecting part 40, a housing 68 that supports the contact pin 70, And two pressing portions 78 provided symmetrically to press the pressing portion 70 against the electrical terminals 48. [

The pressing portion 78 has a rotation cam 72 and a rotation cam support portion 76 for supporting the rotation cam 72, respectively. The rotation cam 72 rotates so that the contact portion 74 of the rotation cam 72 and the contact pin 70 moves in the direction of the connection piece 40 so that the contact pin 70 contacts the electrical terminal 48 To be brought into contact with each other. The rotation cam support portion 76 receives a reaction force when the rotation cam 72 presses the contact pin 70, so that the rigidity should be sufficiently increased to prevent deformation. Therefore, the thickness of the rotation cam supporting portion 76 is increased and the thick portion is protruded to the outside of the housing 68.

The rotation cam 72 includes a circumferential portion 75 having a distance from the center thereof and a cut portion 77 having a distance from the center to the circumferential portion. The contact pins 70 are arranged side by side in two rows symmetrically with respect to the connecting part 40. As the two rotation cams 72 rotate, the two pressing portions 78 press the plurality of contact pins 70 arranged on the left and right sides, respectively.

The contact pin 70 includes a contact portion 74 that contacts the electrical terminal 48 of the connecting part 40. [ The contact portion 74 slides along the electric terminal 48 while contacting the electric terminal 48 when the pressing portion 78 presses the contact pin 70. As a result, the surface of the electrical terminal 48 is scrubbed to remove the oxide film and the dirt, so that the contact pin 70 can be surely brought into contact with the electrical terminal 48.

A handle 52 for rotating the rotation cam 72 is provided on the outer circumferential side of a plurality of radially arranged connectors 50 as a plan view and a side view of the connector 50 as shown in Fig. Respectively. The handle 52 includes a lever portion 56 connected to the rotation cam 72 and extending in the radial direction of the rotation cam 72 and a lever portion 56 attached to the tip of the lever portion 56 and extending in the axial direction of the rotation cam 72 And a handle operating portion 60 having a spherical outer surface is further provided at the distal end of the extending portion 58. [ In FIG. 2, reference numerals 62 and 64 denote mounting portions provided for fixing the connector 50. Bolts were inserted into the mounting portions 62 and 64, and the mounting portions 62 and 64 were fastened to the fixing portions having bolt holes by fastening them with bolts.

However, when the contact pin 70 contacts the electrical terminal of the connecting part 40 at once, the power and control signal parts of the electrical terminal become incomplete, causing a data error or damaging the connecting part 40 .

Further, when a plurality of conventional connectors 50 are provided and are provided adjacent to each other, there is a problem that a minute gap is formed between the connectors 50, and the dimensions of the connectors 50 are not stable.
