Electric connector base

Abstract

A base of an electric connector comprises a plurality of side walls enclosed to form a terminal area, a plurality of division walls, and a plurality of terminal accommodating holes, wherein, the terminal accommodating holes are arrayed in the terminal area; the division walls are arranged between the adjacent terminal accommodating holes in a crossing way; the division wall arranged towards a first direction is defined as a first division wall, while the division wall arranged towards a second direction defined as a second division wall; at least a thickening area is formed in the terminal area; the thickening area is at least connected with one side wall, and comprises a plurality of division walls continuously arranged and connected with the side wall; thickening parts are formed by the division walls continuously arranged at least in same identical direction in the thickening area; and the sectional areas of the division walls with the thickening parts are larger than the sectional areas of the division walls in other identical directions outside the thickening area. The invention can avoid the problems of buckling deformation and incomplete mold caused by over centralization of local stress generated as the area is filled finally, so as to increase the yield of a formed body.

Description

technical field [0001] The invention relates to an electrical connector base, in particular to an electrical connector base which can be provided with conductive terminals arranged in an array. Background technique [0002] An electrical connector generally used to connect a circuit board to a chip module such as a central processing unit includes a base and a plurality of conductive terminals, and a plurality of terminal accommodating holes arranged in an array are formed on the base for the plurality of terminals. set of conductive terminals. Due to the improvement of the signal processing speed of the chip module and the demand for miniaturization, the plurality of conductive terminals must be arranged in a high-density array, and the interval width between the terminal accommodating holes on the base needs to be reduced, that is, the capacity of each terminal The partition walls between the holes are thinned. In addition, the base is generally made by plastic injection...

Problems solved by technology

[0005] However, the aforementioned patents did not solve the problem of the time difference between the filling of the molten material at different positions during the forming process of the electrical connector base, and the patent No. I224885 can only be applied to devices that have a central hole and can be set through the central hole. For electrical connectors with a gate structure, there is still room for improvement in how to solve the problem of stress concentration or insufficient mold filling caused by the time difference of molten material filling during the forming process of the base
