Abstract

The utility model discloses a connector and consists essentially of a base body fixedly arranged on a circuit board, a cover body articulated at one end of the base body, and a driving rod used to press and fix the cover body on the base body. The driving rod includes an articulation section articulated on the base body, a pressing section and a driving section protruded by the articulation section, wherein the driving section is further provided with a connection section shaped by extending of the articulation section, a bending section extended by the end of the connection section, and an operating section extended by the end of the bending section. The plane of the bending section and the operating section is inclined to that of the connection section and the articulation section. When the electrical connector is closed, the distance between the operating section and the circuit board is larger than that between the connection section and the circuit board, which therefore increases the operating space of the operating section and brings more convenience for user to operate the driving rod.

Description

Electric connector

[technical field]

The utility model is about a kind of electric connector, refers to a kind of electric connector that electrically connects planar grid chip and circuit board and have preferable operating characteristics especially.

[background technology]

With the develop rapidly of computer chip (the referring to CPU especially) speed of service, its packing forms is in continuous variation, and the also constantly development of the structure of the electric connector of carries chips.Stitch grid array (PGA) Chip Packaging is now generally used, and the electric connector that is used to carry this chip also is welded in printed circuit board (PCB) in a large number, and this technology can announce the 5th, 456 with reference to United States Patent (USP), No. 613.But, the traditional electrical connector need utilize plain conductor terminal supportor to be drawn the circuit that is connected to chip internal, not only this lead-in wire program raises the cost and increases the assembling volume (usually, plain conductor draws the encapsulation volume of receiving terminal supportor, approximates four times of former chip volume), in addition, because of terminal supportor lengthening circuit paths, resistance is increased,, the phenomenon of signal entanglement very easily occurs if in higher transmission environment.Thereby another kind of Chip Packaging form one ball-shaped grid array (BGA) encapsulation makes volume only be 1/3rd of PGA Chip Packaging because of it shortens signaling path by the tin ball, and the trend that replaces PGA arranged, these technical literatures please refer to United States Patent (USP) and announce the 5th, 419, No. 710.

Can reduce signal transmission path and make the packing forms of encapsulation volume minimum is planar lattice array (LGA) encapsulation, its chip utilizes conductive spacer to reach by interference fit mutually with the conductive spacer on the corresponding electric connector and electrically conducts, its correlation technique document please refer to " Nonlinear Analysis HelpsDesign LGA Connectors " (Connector Specifier, February, 2001), relevant patent please refer to United States Patent (USP) and announces the 5th, 192, No. 213, the 5th, 199, No. 889, the 5th, 232, No. 372, the 5th, 320, No. 559 and the 5th, 362, No. 241 and the 6th, 485, No. 320 grades disclose.

Fig. 1 has disclosed a kind of planar lattice array relevant with the utility model (LGA) electric connector 7, it comprises matrix 71, movably is articulated in the lid 72 of matrix 71 1 ends and in order to press solidly the drive rod 73 of lid 72 on matrix 71, and this drive rod 73 comprises articulated section 731, press section 732 and drive division 733.This drive division 733 can rotate between horizontal level and vertical position, rotates to drive press section 732, and lid 72 is provided with a button hook 721 that cooperates with press section 732.After the planar lattice array chip is installed in this electric connector 7, closed lid 72 is also stirred drive division 733 press section 732 is pressed on the button hook 721 of lid 72, guaranteeing the retain strength between planar lattice array chip and this electric connector 7, and then guarantee the electric connection that the two is stable.

Because during electric connector 7 closures, the drive division 733 of drive rod 73 is horizontal, distance is less between itself and the circuit board, be with when the operator with hand during with drive division 733 spin-ups, the operating space is less, operator's finger very likely touches other electric component on circuit board or the circuit board, is not easy to operation.

[utility model content]
