See also Fig. 1, a kind of existing electric connector 6 relevant with the utility model is in order to electrically connect planar lattice array wafer module (not shown) to printed circuit board (PCB) (not shown), it comprises that the framework 61 and of one " returning " font structure is snapped in the pedestal 62 of this framework 61, wherein respectively be provided with location hole 611 in these framework 61 relative both sides, be provided with a plurality of grooves 612 in the adjacent both sides of framework 61, and respectively establish a block button hole 613 in two diagonal positions of this framework 61, these block button holes 613 are shoulder hole; Pedestal 62 is a tabular, zone is provided with a plurality of terminal holes 621 that are arranged in the middle of it, be provided with the bayonet unit 622 that corresponds to the block button hole of establishing on the framework 61 613 in pedestal 62 relative two diagonal positions, this bayonet unit 622 is a forked, be provided with in pedestal 62 adjacent both sides a plurality of correspond to the groove 612 established on the framework 61 support stops 623, and be provided with reference column 624 corresponding to the location hole of establishing on the framework 61 611, during with framework 61 and pedestal 62 buckle assembly, in the ladder block button hole 613 that the bayonet unit 622 buckle assembly of establishing on the pedestal 62 are established to the framework 61, reference column is gone in the location hole 611 for 624 groups, support stops 623 then appearance go into groove 612.Because bayonet unit 622 be forked, comparatively fragile with the bound fraction of pedestal 62, in the buckle process, this part easily ruptures, and causes thus that pedestal 62 and framework 61 windings are insecure and is separated from each other easily.

[utility model content]

The purpose of this utility model is to provide a kind of electric connector, refers to that especially a kind of pedestal cooperates firm and the bigger electric connector of structural strength with framework.

The purpose of this utility model is achieved in that the utility model electric connector comprises pedestal and the framework that is interlocked with pedestal, wherein pedestal is provided with a plurality of terminal holes of rectangular arrangement that are in order to accommodate a plurality of conducting terminals, respectively convex with arc boss in the pedestal dual-side, on these boss, be provided with reference column, each extension is provided with bayonet unit in relative two diagonal angles of pedestal, this bayonet unit is solid semi-cylindrical, and be provided with clamping part away from an end of pedestal in bayonet unit, framework is " returning " shape structure, its relative dual-side respectively be provided with pedestal on the corresponding location hole of reference column established, and with framework two diagonal angles be provided with pedestal on the corresponding block button hole of bayonet unit established, and these block button holes are shoulder hole, are provided with step in it.When pedestal and assembling frame, the reference column group of pedestal is gone in the location hole, bayonet unit feeds the block button hole of framework, and the clamping part on it is snapped in the step of block button hole.

Compared with prior art, the utlity model has following advantage: because of the bayonet unit of establishing on the pedestal is the filled circles column, its intensity is bigger, utilizes the affixed pedestal of this bayonet unit on framework, the matching relationship firm stable.

[embodiment]

See also Fig. 2 to Fig. 4, the utility model electric connector 1 electrically connects planar lattice array (LGA) wafer module (not shown) to printed circuit board (PCB) (not shown) in the plane mode of pushing, the framework 3 that it comprises pedestal 2 and is snapped in pedestal 2.

Pedestal 2 is rectangular-shaped, and its centre is run through pedestal 2 and is provided with the terminal hole 21 of a plurality of rectangular arrangements in order to ccontaining conducting terminal (not shown), respectively be provided with an arc shape first boss 22 in pedestal 2 relative dual-sides, extend on each first boss 22 and be provided with half-terete reference column 221, relative two diagonal angles in pedestal 2 are provided with second boss 23 along the diagonal extension, in present embodiment, second boss 23 is two, on each second boss 23, extend in the same way and be provided with bayonet unit 231 in the bearing of trend of reference column 221, the shape of the profile of this bayonet unit 231 remainder that is a solid cylinder behind the plane cut-out that is parallel to central axis, each bayonet unit 231 comprises that the base portion 2311 that is extended by pedestal 2 reaches around the clamping part of being located on the base portion 2,311 2312 (please join Fig. 4), wherein the width of this clamping part 2312 is greater than the width of base portion 2311, and an end of clamping part 2312 is provided with inclined-plane 2313.In addition, be provided with a plurality of stops 24 that support in any adjacent dual-side of pedestal 2, in present embodiment, be provided with two in a side and support stops 24, its adjacent side is provided with one and supports stops 24.

Framework 3 is " returning " font structure, the position of the reference column of establishing on corresponding to pedestal 2 in its relative both sides 221 is provided with location hole 31, the shape approximation of the reference column 221 that the shape of location hole 31 and pedestal 20 are established, the position of the bayonet unit of establishing on corresponding to pedestal 2 in 3 liang of diagonal angles of framework 231 is provided with circular card button hole 32, these block button holes 32 are shoulder hole, and in this block button hole 32, be provided with step 321, corresponding to the position of supporting stops 24 of establishing on the pedestal 2, the adjacent dual-side of framework 3 is provided with a plurality of grooves 33.
