Description

Reinforced electric connector

[technical field]

The invention relates to a kind of electric connector, especially refer to a kind of can be in order to electrically connect the electric connector of planar grid chip module and circuit board.

[background technology]

Lga connector 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, as shown in Figure 5, one frame shape metal stiffening device 91 is installed on the matrix 90 of electric connector 9, it is by the moulding of metal material integrated punching, can effectively increase the intensity of matrix 90, avoid in use damaging, improve the stability of electric connector because of being stressed.

But; because in actual use; matrix 90 bears big active force at the two ends that lid 92 and press device 93 are installed; be that above-mentioned two ends may be lifted and make matrix 90 distortion; therefore only need guarantee that matrix 90 gets final product in the intensity that connects on the above-mentioned direction of both ends; and frame shape stiffening device 91 is except that the intensity that increases above-mentioned direction; also increased the intensity that matrix 90 is provided with the two ends of lid 92 and press device 93; thereby frame shape stiffening device 91 need take relatively large metallic plate in the punching production process, thereby increases production cost.

[summary of the invention]

Order of the present invention provides a kind of reinforced electric connector that both can increase the intensity of insulating body.

Another object of the present invention provides a kind of reinforced electric connector that can effectively control production cost.

The object of the present invention is achieved like this: the invention relates to a kind of reinforced electric connector, but it press device that comprises thereon matrix of carries chips module, is fixedly arranged on stiffening device on the matrix, movably is installed in the lid of matrix one end and is installed in the matrix other end.Wherein this stiffening device is a lengthwise shape channel-like configuration, and is immobilizated in a side of matrix by certain way, and an end of this side and matrix installing lid is adjacent, and promptly stiffening device is immobilizated in matrix and installs on the side between the two ends of lid and press device.

Compared with prior art, advantage of the present invention is: the strip stiffening device that is provided with along the side of the stressed easy bending of insulating body work, can guarantee insulating body intensity on this direction, and be not provided with the two ends installing stiffening device of lid and press device at matrix, so can save material, thereby reduce production costs.
