Description
[technical field]
The invention relates to a kind of socket connector, especially refer to a kind of in order to electrically connect the socket connector of chip module and circuit board.
[background technology]
Usually, land grid array package is electrically connected to the lga socket connector of circuit board, as " Nonlinear Analysis Helps Design LGA Connectors " (Connector Specifier, February 2001) disclose, generally have lamellar and be connected to the insulating body of circuit board, this insulating body middle part is a conduction region, be equipped with plurality of conductive terminals in conduction region, design feature because of the land grid array package electric conductor, these conducting terminals generally have better elasticity and are stretched on outside the insulating body, need insulating body to be applied one and push external force by other assembly, and make after the conducting terminal generation strain electric conductor of the elastic force extruding land grid array package by conducting terminal, thereby reach firmly electrically conducting of conducting terminal and land grid array package electric conductor.After these lga socket connectors were connected to circuit board, these conducting terminals electrically conducted away from the other end of land grid array package and the conducting strip of circuit board, thereby reached being electrically conducted of land grid array package and circuit board.
As United States Patent (USP) the 4th, 998, No. 866 and the 5th, 498, No. 166 disclose, for making the terminal of socket connector have good elasticity, it generally is provided with than long cantilever, and is provided with the junction that the electric conductor with land grid array package is electrically conducted in the end of this cantilever.
The concrete set-up mode of the terminal structure of these socket connectors can be referring to Fig. 1 and Fig. 2, " U " shape cantilever 92 that socket connector terminal 9 has tabular holding parts 91 and extends from holding parts 91 middle parts, this cantilever 92 is provided with junction 921 in its extending end near holding parts 91, and is provided with contact site 922 in its end away from holding parts 91.After these conducting terminals 9 were placed in the terminal containing slot 81 of socket connector 8, its junction 921 and contact site 922 protruded in two relatively outside the surface of socket connector 8 respectively.
After land grid array package 6 is connected to socket connector 8, the junction 921 of socket connector terminal 9 and contact site 922 contact with the conducting strip 71 of circuit board 7 and the electric conductor 61 of land grid array package 6 respectively, and the cantilever 92 of socket connector terminal 9 is subjected to the extruding of land grid array package 6 and circuit board 7 and strain takes place.Produce elastic force after cantilever 92 distortion, make junction 921 and contact site 922 push the conducting strip 71 of circuit board 7 and the electric conductor 61 of land grid array package 6 respectively, thereby can guarantee socket connector terminal 9 and land grid array package 6 and 7 firm being electrically conducted of circuit board.
Yet, the junction 921 of socket connector terminal 9 is located at than on the long cantilever 92, after land grid array package 6 and circuit board 7 are electrically conducted, electric current is the conducting strip 71 that just arrives circuit board 7 after the electric conductor 61 of plane Background Grid array packages 6 is flowed through the long cantilever 92 of conducting terminal, the path of conducting terminal is very long because electric current is flowed through, total electrical impedance is bigger, so it is more to produce heat, thereby the heat that whole conducting terminal is produced is also more.Because the frequency of now general telecommunication transmission is higher, the heat that produces owing to the electrical impedance increase can be bigger like this, if the land grid array package heat radiation is bad, then can cause component wear because accumulating too many heat, shorten component life or influence the normal function of circuit, and and then influence the performance that connects of land grid array package and circuit board.
[summary of the invention]
The object of the present invention is to provide a kind of socket connector, especially referring to a kind ofly can provide the socket connector that well connects performance between chip module and circuit board.
The object of the present invention is achieved like this: socket connector of the present invention comprises connector body and accommodates conducting terminal inside that this conducting terminal comprises that installation portion reaches the extension from installation portion one side extension.Extension is " U " shape, and it is provided with first, second extension and free end, and is provided with first contact site that connects with circuit board between first and second extension, is provided with second contact site that connects with chip module between second extension and free end.When chip module is depressed second contact site of conducting terminal, this free end and installation portion butt, and form successively first conductive path, and successively via second conductive path of chip module, second contact site, installation portion, first contact site and circuit board via chip module, second contact site, first contact site and circuit board.
Compared with prior art, the present invention has following advantage: because of first conductive path becomes relation in parallel with second conductive path, so the heat energy that electrical impedance when having reduced the telecommunication transmission and electric connector terminal produce, thereby provide the good telecommunication between chip module and circuit board to connect performance.
