Description
[technical field]
The utility model refers in particular to the stable electric connector of a kind of electric connection planar grid wafer module and circuit board and assembly relation about a kind of electric connector.
[background technology]
The packing forms of electric component is in continuous variation, and the also constantly development of structure of carrying the electric connector of these electric components.For reduce the encapsulation volume between electric component and electric connector and reduce electric component and electric connector between the electric signal transmission path, generally on electric component, establish the electrical contact zone of sheet, press on the face way of contact on the electric connector of counter structure,, the electric signal transmission path reduces to transmit resistance so that reducing, can effectively prevent the signal disorder that high-speed transmission environment causes, its correlation technique document please refer to Nonlinear Analysis Helps Design LGA Connectors (Connector Specifier, February 2001), relevant patent documentation can be with reference to United States Patent (USP) the 6th, 027, No. 345, the 6th, 146, No. 151, the 6th, 146, No. 152, the 6th, 164, No. 978 and the 6th, 293, announcement such as No. 806 grades.
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.

Fig. 3 is the three-dimensional combination figure of the utility model electric connector.
Fig. 4 is the broken section enlarged drawing at IV indication place among Fig. 3.
[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.
See also Fig. 3 and Fig. 4, during assembly the utility model electric connector 1, the reference column of establishing on the pedestal 2 is gone into for 221 groups in the location hole of establishing on the framework 3 31, in this simultaneously, the bayonet unit of establishing on the pedestal 2 231 is also organized and is gone in the block button hole of establishing on the framework 3 32, and establish on the pedestal 2 support the groove 33 of stops 24 by establishing on the framework 3, wherein these support when stops 24 is used to install planar lattice array wafer module (not shown) to the utility model electric connector 1 and limit the position of this wafer module, thereby guarantee that the wafer module electrically contacts with the good of the utility model electric connector 1.Because the shape of the profile of the bayonet unit of establishing on the pedestal 2 231 remainder that is a solid cylinder behind the plane cut-out that is parallel to central axis, and its clamping part 2312 has inclined-plane 2313, utilize this inclined-plane 2313 can make bayonet unit 231 easily organize the block button hole of establishing on the framework 3 32, in addition, because the width of the clamping part 2312 of bayonet unit 231 is greater than the base portion of bayonet unit 231, and block button hole 32 is provided with step 321 for shoulder hole, so, this bayonet unit 231 can be snapped in the step 321 of block button hole 32, thereby makes pedestal 2 stable with framework 3 assembly relation.And because bayonet unit 231 is an integral body, its intensity is preferable, in the assembly process, and difficult the fracture, and then guarantee pedestal 2 and the affixed reliability of framework.
