The utility model electric connector is not easy to make the base body generate curving distortion, thereby the order property of the base body bottom face can be ensured to make the welding of the end and the circuit plate good, which is beneficial for the electric connection between the electric connector and the circuit plate.

Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, especially about the electric connector of a kind of connection LGA (land grid array, planar lattice array) chip module.

[background technology]

At present some chip module adopts the form of LGA, realizes contacting of both conducting positions with compress mode between corresponding with it electric connector and the chip module, and reaches stable telecommunication transmission between the two.

Be present common LGA type electric connector as shown in Figure 1, it comprise matrix 1, and an end be articulated in lid 2 on the matrix 1, between matrix 2 and lid 2, be provided with one and withhold device 3.This is withheld device 3 and comprises pressing lever 4 and the extended drive rod 5 of self-pressing bar 4 one ends, this drive rod 5 can change between horizontal level and vertical position, these lid 2 one ends are provided with a hook 6 that cooperates with pressing lever 4, and corresponding drive rod 5 ends of these matrix 1 one sides are provided with tongue piece 7.After chip module (not drawing among the figure) is installed in this electric connector, closed lid 2 also rotates drive rod 5 pressing lever 4 of withholding device 3 is pressed on the hook 6 of lid 2, at this moment lid 2 presses on the chip module, then drive rod 5 ends are fastened on tongue piece 7 belows on the pedestal 1, with lid 2 and matrix 1 mutual fixing, so that chip module is fixed in this electric connector.

The prior art defective is: the drive rod of withholding device is positioned at a side of matrix, behind matrix and loam cake fastening, matrix can be subjected to withholding downward pressure of device and the pulling force that makes progress, its stress point is denoted as an A respectively and puts B in Fig. 1, because being subjected to the stress point (promptly putting B) of pulling force upwards, matrix is positioned at the two ends of withholding device, promptly roughly be positioned on two diagonal angles of matrix, can make the matrix bottom surface produce bigger out-of-flatness like this, thereby cause failure welding between the terminal that is located on the matrix and the circuit board, influence the electric connection of electric connector and circuit board.

Thereby press for a kind of can guarantee and circuit board has the LGA electric connector of good electric connection.

[summary of the invention]

The purpose of this utility model is to provide a kind of energy assurance and circuit board to have the electric connector of good electric connection.

The utility model electric connector, the lid that it comprises matrix, can be articulated in pedestal one end and interfix with matrix, and be located at the device of withholding between matrix and the lid, it is characterized by: this is withheld device and comprises pressing lever and the extended drive rod of difference self-pressing bar two ends approximate vertical, and this matrix is provided with the tongue piece that is used for fixing drive rod.

Compared with prior art, the utility model electric connector is difficult for making matrix to produce buckling deformation, thereby can guarantee the planarization of matrix bottom surface, makes the welding of terminal and circuit board good, helps the electric connection of electric connector and circuit board.

[description of drawings]

Fig. 1 is the stereogram of the electric connector relevant with the utility model.

Fig. 2 is first kind of execution mode of the utility model electric connector.

Fig. 3 is second kind of execution mode of the utility model electric connector.

Fig. 4 is the third execution mode of the utility model electric connector.

Fig. 5 is the 4th a kind of execution mode of the utility model electric connector.

[embodiment]

Figure 2 shows that first kind of execution mode of the utility model electric connector.This electric connector comprise matrix 10, and an end be articulated in lid 20 on the matrix 10, between matrix 10 and lid 20, be provided with one and withhold device 30.This withhold device 30 comprise pressing lever 32 and respectively self-pressing bar 32 two ends approximate vertical extend roughly isometric drive rod 34, this drive rod 34 can change between horizontal level and vertical position, these matrix 10 both sides are to being respectively equipped with tongue piece 12 by drive rod 34 ends, this tongue piece 12 is roughly along pedestal 10 center line symmetries, with fixed drive bar 34, assurance lid 20 was fixed with cooperating of matrix 10.

The utility model electric connector matrix also can be subjected to withholding the pulling force that device makes progress, but because the utility model matrix is equipped with tongue piece and withholds device and match in both sides, the stress point of its pulling force is matrix both sides (being the some C that indicates among Fig. 2), understand easily, compared with prior art, this structure is difficult for making matrix to produce buckling deformation, thereby can guarantee the planarization of matrix bottom surface, make the welding of terminal and circuit board good, help being electrically connected electric connection with circuit board.

Fig. 3 is second kind of execution mode of the utility model electric connector.With first kind of different being of execution mode: in the present embodiment, tongue piece 42 on its matrix 40 is positioned at an end that is articulated with lid 44, still along matrix 40 center line symmetries, base is withheld vertical again inflection behind drive rod 47 self-pressing bars 48 two ends vertical extent one segment distance of device 46, makes its end can be fastened on tongue piece 42 belows.At this moment the stress point of matrix 40 suffered pulling force compared with prior art, equally also can reduce the amplitude of buckling deformation for a D.

Its tongue piece also can be located on the electric connector lid, as shown in Figure 4, this tongue piece 50 is located at the both sides of lid 52, as shown in Figure 5, this tongue piece 60 is located at an end of lid 62, and is same, these structures also can reduce the amplitude of buckling deformation, thereby can guarantee the planarization of matrix bottom surface, make the welding of terminal and circuit board good, help being electrically connected electric connection with circuit board.

Understand easily, this pedestal is the carries chips module directly, also can comprise a pedestal and be contained in and be used for the supporting body of carries chips module in the pedestal, and, this pedestal can be installed with plurality of terminals, the current-carrying part that makes chip module and circuit board also can not established terminal via the indirect conducting of terminal, makes the direct conducting of current-carrying part of chip module and circuit board.
