Abstract

The utility model discloses an electric connector, which is used for electrically connecting land grid array (LDA) and a circuit board. The utility model comprises a basal body fixedly arranged on the circuit board, a cover body which can be movably arranged at one end of the basal body, and a pressing device used for pressing and fixing the cover body on the basal body, wherein, the basal body is provided with a bearing part which can bear a chip module; an anti-bending metal lining board is embedded on the basal body; the lining board comprises a flat board body and a bending part formed by bending from the periphery of the flat board body. Because the lining board with a bending edge is embedded, the intensity of the basal body can be effectively enhanced so as to prevent the basal body from being crushed caused by large stress when the chip module of the land grid array is pressed and fixed on the basal body.

Description

Electric connector

[technical field]

The utility model is about a kind of electric connector, especially refers to a kind of in order to connect the electric connector of planar lattice array chip module and circuit board.

[background technology]

Connector of planar lattice array generally uses with the planar lattice array chip module, and is to realize contacting of the two conducting position in the mode of pushing between this connector and the chip module, and reaches stable telecommunication transmission between the two.

Traditional connector of planar lattice array comprises that the insulating body that is connected with circuit board reaches to push the lid of mode fixed pan grid array chip module on electric connector, and be provided with a press fastening device between matrix and the lid to guarantee the retain strength of the two, for guaranteeing stable electric connection between planar lattice array chip module and the matrix, above-mentioned retain strength needs enough big, yet, because matrix is formed by the plastic material manufacturing usually, and its thickness of slab is again because of the product thickness restriction, matrix thickness can not be too big, thereby intensity is less, the impaired even fracture of easy in actual use stressed bending.

After this, in order under the prerequisite that does not increase matrix thickness, to improve the intensity of matrix, in the manufacture process of injection mo(u)lding, be embedded with a tabular sheet metal in matrix inside.But because above-mentioned sheet metal bend resistance insufficient strength, in actual use, matrix still can be out of shape because of insufficient strength, and then influences the machinery and the electric property of electric connector.

[utility model content]

The purpose of this utility model provides a kind ofly avoids in chip module installation process matrix because of the stressed electric connector that damages greatly.

The purpose of this utility model is achieved in that this electric connector comprises the matrix that is fixedly arranged on the circuit board, movably is installed in the lid of matrix one end and in order to press solidly the press device of lid on matrix, wherein matrix is provided with supporting part, and the carries chips module thereon, and matrix is embedded with the bending resistance metal backing, and this liner plate comprises platysome and the kink that is bent to form from this platysome periphery.

Compared with prior art, the utlity model has following advantage: matrix is embedded with the bending resistance metal backing of tool kink, can significantly increase the intensity of matrix, even suffered chucking power more can not make the matrix damage fracture more yet when mounting plane grid chip module, thereby guarantees electric connector favorable mechanical and electric property.

[embodiment]

See also Fig. 1 and Fig. 2, the utility model electric connector 1 is to electrically connect planar lattice array chip module 6 and circuit board 5 with the surface form of pushing, it comprise the matrix 2 that is fixedly arranged on the circuit board 5, movably be articulated on the matrix 2 and can in open and make position between the lid 3 that rotate, and press solidly lid 3 on matrix 2 and then the press device 4 of fixing planar lattice array chip module 6.

Matrix 2 is provided with the supporting part 20 of a load plane grid array chip module 6, and a lateral edges of this supporting part 20 is provided with the hinge device 22 that can be rotatably connected with lid 3.Wherein supporting part 20 is a tetragonal hollow structure, and this hollow space has been installed with push type jockey 201 (Fig. 4 reference), is electrically connected to circuit board 5 thereon and with it in order to shelve planar lattice array chip module 6.

Please in conjunction with consulting Fig. 3 and Fig. 4, the inside of matrix 2 is to being embedded with an approximate tetragonal liner plate 24 in hollow supporting part 20 positions, this liner plate 24 is by the bigger material of bending strength, normally the metal material punching out forms, it comprises a hollow platysome 241, reach from 241 4 edges of this platysome kink 240 to planar lattice array chip module 6 place lateral bucklings, the hollow space of this platysome 241 is greater than the hollow space of matrix 2 supporting parts 20, and these kinks 240 are roughly vertical with platysome 241, and this kink 240 also can outwards partly extend the back bending and form from the edge of platysome 241, and the hollow space of platysome 241 is corresponding with the hollow space of supporting part 20.

The platysome 241 of above-mentioned liner plate 24 also can fit in bottom one side of matrix 2 near circuit board 5, and its kink 240 is embedded in the matrix 2.

Lid 3 is hinged by the hinge hole 30 of an end and the hinge device 22 of matrix 2, this lid 3 comprises framework 31 that presses solidly planar lattice array chip module 6 and the compression zone 310 that extends away from hinge hole 30 1 side direction matrixes 2 directions from framework 31, and this compression zone 310 is away from the opening of hinge device 22 1 sides on the framework 31.Said frame 31 is the tetragonal structure of a hollow, its be provided with some press solidly planar lattice array chip module 6 press solidly sheet 311, this presses solidly sheet 311 and extends to the bending of matrix 2 directions.

Press device 4 is arranged at the opposite side of matrix 2 away from hinge device 22, it comprises that one is fixedly arranged on the axle bed 41 on the matrix 2 and is inserted in this axle bed 41 and rotatable swing arm 42, this swing arm 42 comprises the press-side 422 of pushing lid 3 and can pass the both sides of axle bed 41 respectively for the struck side 420 of stirring swing arm 42 rotations.Matrix 2 is provided with the first button card, 43 and second button in the bilateral symmetry of axle bed 41 and blocks 44, in order to clamping swing arm 42 in the opening and closing position.

Be installed in the push type jockey 201 of matrix 2 hollow spaces when planar lattice array chip module 6 after, rotation lid 3, make being posted by on the chip module 6 of its framework 31 with pressing solidly sheet 311 no pressure, stir the struck side 420 of press device 4 swing arms 42 then, and then the press-side 422 that drives swing arm 42 presses solidly the compression zone 310 in framework 31, thereby with 6 firm being immobilizated between matrix 2 and the lid 3 of planar lattice array chip module.And, because matrix 2 is embedded with the bending resistance metal backing 24 of tool kink 240, can significantly increase the intensity of matrix 2, even more can not making matrix 2 damage, above-mentioned chucking power do not fracture, thus the favorable mechanical and the electric property of assurance electric connector 1.
