Description

Electric coupler component

[technical field]

The invention relates to a kind of electric coupler component, refer to a kind of electric coupler component especially with insulating body, first lid and second lid.

[background technology]

In the circuit that is made of several actives and passive device, Electronic Packaging such as chip module are the miniaturized electric sub-elements, and in use safe and reliable in order to guarantee it, nearly all chip module all must be tested before installation.Chip module is carried out long high temperature running, can make and exist the chip module of defective to lose efficacy as early as possible, eliminate thereby defective chip module screened, and by the chip module of test soldered or be assembled to electronic terminal product after just can use safely, can premature failure.Electric connector is used to accommodate chip module, and it is electrically connected to test board it is carried out high temperature running test.Relevant prior art such as United States Patent (USP) disclose for the 5th, 609, No. 497 and the 5th, 100, No. 332.

See also Fig. 6 and Fig. 7, existing a kind of electric coupler component 1 ', in order to carry Electronic Packaging (as chip module) and to be electrically connected to circuit board (as test board), it mainly comprises insulating body 10 ', is contained in the plurality of conductive terminals (not shown) in the insulating body 10 ', first lid 12 ' that is articulated in insulating body 10 ' one end and second lid 14 ' that is articulated with first lid 12 '.

The insulating body 10 ' and first lid 12 ' movably are articulated by first pivot 30 ', and are provided with second pivot 40 ' at the other end of first lid 12 ', by this second pivot 40 ' second lid 14 ' movably are articulated on first lid 12 '.Wherein second lid 14 ' has extended to form a clamping part 148 ' downwards in the end that it articulates first lid 12 '.Insulating body 10 ' is being provided with cross bar 20 ' away from the end installation that first lid 12 ' is installed, this cross bar 20 ' stretches out insulating body 10 ' certain distance, this part of stretching out cooperates with the clamping part 148 ' of second lid 14 ' respectively, so that first lid 12 ' is locked on the insulating body 10 '.In addition, second lid 14 ' is provided with catch member 141 ' in its other end, to fasten with insulating body 10 '.

During use, make first earlier, second lid 12 ', 14 ' is in opening, chip module is placed in the host cavity of insulating body 10 ', then, with first, second lid 12 ', 14 ' rotates to horizontal level, first lid 12 ' is pressed on the insulating body 10 ', second lid 14 ' is pressed on first lid 12 ', and the button hook 148 ' of second lid 14 ' catches on the part that cross bar 20 ' extends two relative lateral surfaces of insulating body 10 ', and catch member 141 ' button is held on the insulating body 10 ', thereby second lid 14 ' is also stablized snap close on insulating body 10 ', this moment, electric coupler component was in closure state, the conducting strip of chip module and the conducting terminal of electric coupler component compress and connect, electric coupler component is able to chip module is electrically connected to test board, then this assembling is carried out the continuous high temperature running to impel defective chip module to lose efficacy as early as possible.

After high temperature test is intact, the catch member 141 ' of second gland 14 ' is rotarily opened from insulating body 10 ', rotate up second lid 14 ' then, the button hook 148 ' of second lid 14 ' is to inner rotary and throw off cross bar 20 ' on the insulating body 10 ', rotate first lid 12 ' at last, make it also be in opening, thereby take out integrated circuit modules, test thereby another integrated circuit modules is electrically connected to test board through test.

Yet, there is defective in the electric coupler component of this structure: through unlatching and closure repeatedly, the clamping part 148 ' of second lid 14 ' may be with cross bar 20 ' wearing and tearing, when wearing and tearing acquire a certain degree, above-mentioned first lid 12 ' may not be stabilized pressure holding on insulating body 10 ', thereby influences the stable electric property of electric coupler component.

[summary of the invention]

The technical problem to be solved in the present invention is to provide a kind of chip module is electrically connected to the electric coupler component of circuit board, and this electric coupler component can reduce wearing and tearing in use, and can reduce maintenance cost after wearing and tearing.

For solving the problems of the technologies described above, electric coupler component of the present invention comprises insulating body, be contained in the plurality of conductive terminals in the insulating body, be articulated in first lid of insulating body one end, and second lid that is articulated in the first lid other end, this second lid is provided with catch member in it away from an end that articulates first lid, be provided with the clamping part that can be held on the insulating body in the relative other end, insulating body is provided with holding part and the cross bar that cooperates with catch member and clamping part respectively, wherein the part that cooperates with clamping part of cross bar is provided with hard sleeve, and this hard sleeve is when second gland is closed and the clamping part interference engagement.

Compared with prior art, the present invention is by the sheathed hard sleeve of the part that matches with clamping part at cross bar, can reduce second lid open repeatedly with closed process in to the wearing and tearing of cross bar, thereby prolong the useful life of electric coupler component, and sleeve is dismantled easily, under the situation of its damage, can be convenient for changing, thus the maintenance cost of minimizing electric coupler component.
