Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, refers to a kind of electric connector that the chip module is electrically connected to printed circuit board (PCB) especially.

[background technology]

As shown in Figures 1 and 2, a kind of existing electric connector 1 of chip module (not shown) to printed circuit board (PCB) (not shown) that be used to electrically connect, it comprises insulating body 10, be contained in plurality of conductive terminals 11, frame in the insulating body is located at the reinforced sheet 12 of insulating body 10 peripheries, is articulated in reinforced sheet 12 1 ends and is used to compress the pressing plate 13 of chip module and is articulated in the driving lever 14 that the reinforced sheet 12 relative other ends are used to pin pressing plate 13.Wherein, driving lever 14 comprises that driving shaft 141 and self-powered moving axis 141 1 ends vertically bend the action shaft 142 of extension, action shaft 142 middle parts are provided with the portion of exerting pressure 1420, described reinforced sheet 12 1 ends are interval with the accepting groove 121 that articulates driving lever 14, described portion 1420 both sides of exerting pressure are contained in the accepting groove 121, described reinforced sheet 12 1 sides also are provided with the latch part 122 of snap close driving lever 14, and the middle part extension of described pressing plate 13 1 ends is provided with compression zone 131.

During assembling, pressing plate 13 is articulated in reinforced sheet 12 1 ends, the driving shaft 141 of driving lever 14 is articulated in the accepting groove 121 of the other end of reinforced sheet 12, then the chip module is inserted in the insulating body 10, and pressing plate 13 is buckled on the chip module, drive driving lever 14 again, the compression zone 131 of 1420 pairs of pressing plates 13 of the portion that exerts pressure of driving lever 14 is exerted pressure, by latch part 122 that driving lever 14 is fixing at last.

But, this mode that pressing plate 13 and driving lever 14 is articulated in the two ends of reinforced sheet 12 respectively, at least there is following defective: at first, when electric connector 1 in the closure or openness process, pressing plate 13 need be opened the both sides that place reinforced sheet 12 separately with driving lever 14, because of circuit board is provided with more electronic component, so the space of opening of pressing plate and driving lever is subjected to some restrictions, and easy and electronic component is interfered, simultaneously the loading or unloading operation inconvenience of chip module; Secondly, because chip module middle part single-point is stressed, occur chip module pressurized imbalance easily, one-sided inclination causes the problem of circuit on electrically conducting.

In addition, in No. the 7207822nd, the United States Patent (USP) of in April, 07 bulletin, disclosed and a kind of driving lever has been placed electric connector on the pressing plate.The driving lever of this electric connector is provided with the portion of exerting pressure, the pressing plate front center is provided with extension, be provided with an arc block plate in extension front-end edge middle part, the portion of exerting pressure of driving lever is articulated in the extension of pressing plate, and arc block plate is used for preventing that driving lever breaks away from pressing plate along the longitudinal direction overexercise of pressing plate.This electric connector is articulated in driving lever on the pressing plate, driving lever and pressing plate are opened all at homonymy, saved the space, the loading or unloading operation of chip module is also more convenient simultaneously, but this electric connector since still the portion that exerts pressure by driving lever to the chip module application of force, still exist chip module middle part single-point to be subjected to force unbalance, cause the problem of circuit on electrically conducting.

Given this, be necessary to provide a kind of improved electric connector in fact, to overcome the defective of above-mentioned electric connector.

[utility model content]
