Abstract

The utility model relates to an electric connector which is used for connecting a chip module. The electric connector comprises a lower cover approximately presenting a frame shape, an upper cover connecting on one end of the lower cover, a fixing part arranged on the other end of the lower cover for fixing the upper cover and the lower cover, and a base contained inside the frame of the lower cover for supporting the chip module; a plurality of conductive terminals which can contact the chip module in a constringent mode are arranged inside the base; the two inner edges of the frame of the lower cover are provided with bulge sections inward in an extending mode, and the bulge sections extend at least over the outer edge of the chip module so as to cause the downward force applied by the upper cover and the upward force applied by the lower cover to be on the same line approximately; the degree of the bending upward and deformation can be decreased, the favorable electric property of the electric connector can be ensured, and the better electrical connection of the chip module can be ensured.

Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, refers to a kind of electric connector that is used to electrically connect the planar lattice array chip module especially.

[background technology]

Prior art can be with reference to shown in Figure 1, the electric connector of existing connection planar lattice array chip module comprises the loam cake 1 and the lower cover 2 of mutual flexible connection, be contained in the base 3 that is used for supporting plane grid array chip module 5 in the lower cover 2 and be used for fixing loam cake 1 and the rocking bar 4 of lower cover 2, be provided with plurality of conductive terminals 6 in the base 3, conducting terminal 6 can compress contact mutually with chip module 5.

During assembling chip module 5, make electric connector be in open state earlier, again chip module 5 is placed on the base 3, and chip module 5 is contacted with conducting terminal 6, then rotate loam cake 1, loam cake 1 is pressed on the chip module 5, and it is fixing with loam cake 1 and lower cover 2 to rotate rocking bar 4 then, and chip module 5 is contacted with conducting terminal 6 compressions.At this moment, base 3 is subjected to the power F2 that makes progress that downward power F1 that chip module applies and lower cover 2 apply, because F1 roughly is positioned at the middle part, and F2 roughly is positioned at two ends, so these two kinds of power can produce a moment to base 3, make the buckling deformation that makes progress of base 3 two ends, the positive force of 5 pairs of central partially conductive terminals 6 of chip module will be too small like this, cause contact impedance excessive, thereby have influence on the electric connection between chip module 5 and the electric connector.

Therefore be necessary to design a kind of novel electric connector, to overcome above-mentioned defective.

[summary of the invention]

The purpose of this utility model is to provide a kind of electric connector, and it can guarantee to electrically connect preferably with the planar lattice array chip module.

In order to reach above-mentioned creation purpose, the utility model electric connector is used to connect chip module, it comprises the lower cover that roughly is frame shaped, be connected in the loam cake of lower cover one end, be positioned at the fixture of the lower cover other end with fixed cover and lower cover, and be contained in down the base that is used for the supporting chip module in the cover frame, be provided with some conducting terminals that can compress contact mutually in the base with chip module, it is characterized in that: lower cover framework two ends inner edge extends internally and is provided with protuberance, and this protuberance extends beyond the outer rim of chip module at least.

Compared with prior art, but at least one end inner edge of the utility model electric connector lower cover framework extends internally and is provided with the protuberance of base for supporting, the power that makes progress that downward power that the loam cake that base is subjected to applies and lower cover apply roughly is located along the same line, so can significantly reduce the make progress degree of buckling deformation of base, guarantee the good electric property of electric connector, assurance and chip module electrically connect preferably.

[description of drawings]

Fig. 1 is the stereogram after existing electric connector and the chip module assembling.

Fig. 2 is the profile of assembling back electric connector lower cover shown in Figure 1 and base.

Fig. 3 is the schematic diagram that the utility model electric connector is connected with chip module.

[embodiment]

Below in conjunction with drawings and Examples the utility model electric connector is further described.

With reference to shown in Figure 3, the utility model electric connector comprises the lower cover 2 that roughly is frame shaped, be connected in the loam cake (not drawing among the figure) of lower cover 2 one ends, (figure does not draw with the rocking bar of fixed cover and lower cover 2 to be arranged in lower cover 2 other ends, certainly also can be the fixture of other various ways such as screw), and be contained in the base 3 that is used for supporting plane grid array chip module 5 in lower cover 2 frames, be provided with plurality of conductive terminals (not indicating) in the base 3, conducting terminal can compress contact mutually with chip module 5.

Below, this base 3 two ends is concaved with depressed part 31, and to should depressed part 31, lower cover 2 framework two ends inner edges extend internally and are provided with the protuberance 21 that can be contained in the depressed part 31, and these protuberance 21 terminal outer rims that surpass chip module 5.Like this, this protuberance 21 can support to base 3 bottoms after the assembling, thereby the power F2 that makes progress that downward power F1 that the loam cake that base 3 is subjected to applies and lower cover apply roughly is located along the same line, therefore two kinds of moments that power produced are very little, even do not have, so can significantly reduce the make progress degree of buckling deformation of base, guarantee the good electric property of electric connector, guarantee and the planar lattice array chip module electrically connects preferably.
