[background technology]

The processing procedure of IC encapsulation comprises that encapsulation is tested to IC, needs the use test socket as the interface that is encapsulated between printed circuit board (PCB).Generally speaking, the test processing procedure is that test package is finished the electrical functionality of product after IC encapsulation, with the integrality on the IC function that guarantees to dispatch from the factory, and to the product tested according to its electrical functionality classification, thereby as IC different brackets product evaluation foundation.

Existing test jack comprises plurality of conductive terminals, be provided with the upper plate in plurality of terminals hole, be assembled in the lower plate of upper plate bottom and be assembled on the upper plate and be provided with the strutting piece of some through holes corresponding with terminal hole.Lower plate is provided with some terminal holes corresponding with upper plate to accommodate conducting terminal, and strutting piece forms a host cavity in order to accommodate the IC encapsulation that is provided with the tin ball.The IC encapsulation can move up and down under the driving of other assembly.In test process, the head of conducting terminal need be given prominence to upper plate and then contact with the tin ball that is arranged in the strutting piece through hole, and outstanding conducting terminal head has and rocks and problem that the normotopia degree is relatively poor, thereby need guide at the lower edge of strutting piece.But when conducting terminal reduced height, the thickness of strutting piece also must reduce, and wanting to make guidance part at the lower edge of strutting piece simultaneously in this situation becomes the quite thing of difficulty.

Therefore, necessaryly provide a kind of improved electric connector, to overcome the defective that the aforementioned electric connector exists.

[utility model content]

The utility model provides a kind of conducting terminal projecting height to reduce, and can prevent that the conducting terminal upper end from rocking and improving the electric connector of conducting terminal normotopia degree.

The utility model is achieved through the following technical solutions: electric connector is used to electrically connect chip module and circuit board, it comprises plurality of conductive terminals, be provided with the upper plate in some upper terminals hole, be assembled in the upper plate bottom lower plate, be assembled in the strutting piece on the upper plate and be assembled in upper plate and lower plate between elastic component.Each conducting terminal has body and lays respectively at the last contact site and the following contact site at body two ends.Lower plate is provided with some lower terminal holes corresponding with the upper terminal hole of upper plate, and the body of conducting terminal is contained in the upper and lower terminal hole, and its upper and lower contact site can protrude out upper plate and lower plate respectively.Strutting piece is provided with some through holes corresponding with the upper terminal hole.Elastic component is for being assembled between upper plate and the lower plate, thereby upper plate can be fluctuated with respect to lower plate.

Compared with prior art, the utility model with electric connector by between upper and lower plate, elastic component being set, upper plate can be fluctuated with respect to lower plate, can be when reducing the strutting piece height, reduce conducting terminal and protrude in the height of upper plate, and then can prevent that the conducting terminal upper end from rocking and improving the normotopia degree of conducting terminal.

[embodiment]

See also Fig. 1 to shown in Figure 2, the utility model electric connector 100 is installed on the circuit board (not icon), in order to test chip module 80 (Fig. 3), it comprises plurality of conductive terminals 10, upper plate 20, is positioned at the lower plate 30 of upper plate 20 belows, places the strutting piece 40 on the upper plate 20 and is located at upper plate 20 and the elastic component 50 of 30 of lower plates.Upper plate 20 and strutting piece 40 also further are assembled on the framework 70.

Upper plate 20 is roughly rectangular, and its upper surface is smooth flat, and upper plate 20 is provided with some upper terminals hole 21.The corner of upper plate 20 is provided with some circular holes 22.Lower plate 30 is roughly rectangular, and it is provided with a depressed part 35, and depressed part 35 is provided with the terminal accommodating district, and the terminal accommodating district is provided with some lower terminal hole 31.Circular hole 22 corresponding positions with upper plate 20 on the depressed part 35 are respectively equipped with the limiting section 32 that is round barrel shape.Limiting section 32 is provided with the locating part 60 that prevents that upper plate 20 from upwards excessively floating.Described limiting section 32 middle parts are provided with accepting hole 33, and described locating part 60 is for being assembled to the screw of accepting hole 33, and as shown in Figure 3, it comprises fixed part 61 and stage portion 62.

See also Fig. 2, Fig. 3 and shown in Figure 5, conducting terminal 10 is small at both ends and big in the middle shape, and each conducting terminal 10 has body 11 and lays respectively at the last contact site 12 and the following contact site 13 at body 11 two ends.The body 11 of conducting terminal 10 be contained in the upper and

lower terminal hole

21,31 and can be in upper and

lower terminal hole

21,31 strain, its upper and

lower contact site

12,13 protrudes out upper plate 20 and lower plate 30 respectively.

Elastic component 50 is assembled between upper plate 20 and the lower plate 30, is on the limiting section 32 that is sheathed on lower plate 30 and two ends difference butt upper plate 20 and lower plate 30.Elastic component 50 can fluctuate upper plate 20 with respect to lower plate 30 and conducting terminal 10 between the primary importance and the second place.
