Abstract
The utility model discloses an electric connector which is used to electrically connect a chip module to a printed circuit board. The electric connector comprises an insulating body and electrically-conductive terminals. The insulating body consists of a bottom wall and side walls extending from the bottom wall. The bottom wall comprises an upper bottom surface for bearing the chip module and a lower bottom surface mounted to the printed circuit board. The lower bottom surface is extended with a positioning column which is used to fix the insulating body to the printed circuit board. Meanwhile, the lower bottom surface is also provided with a concave groove which can be buckled with the hook part of a fixture. By uniform application of force on the fixture, the insulating body can be removed from the printed circuit board.
Description
[technical field]
The utility model relates to a kind of electric connector, relates in particular to a kind of electric connector that can remove its insulating body from printed circuit board (PCB) easily.
[background technology]
A kind of grid array (Land Grid Array, LGA) electric connector, be used to electrically connect the chip module to printed circuit board (PCB), it comprises insulating body and conducting terminal, insulating body comprises flat diapire and extends the sidewall of setting from diapire, diapire and sidewall are formed a receiving space and are used to accommodate the chip module, diapire comprises the upper bottom surface of accepting the chip module and the bottom surface that is mounted to printed circuit board (PCB), the conducting terminal of this kind electric connector adopts the mode of non-welding to be connected to printed circuit board (PCB), its insulating body bottom surface extension is provided with the location hole interference engagement that is provided with on some reference columns and the printed circuit board (PCB), reach the purpose of fixed insulation body to printed circuit board (PCB), so it is quite firm that reference column cooperates with location hole, because behind the insulating body location, that fits between its bottom surface and the printed circuit board surface is quite tight, make when removing insulating body, cause not having ground can supply to grasp, bring a very big difficult problem to removing insulating body, even, make the electric connector disabler because the imbalance of the application of force also can cause the phenomenon of reference column fracture.
So necessary disappearance to above-mentioned existing electric connector is done necessity of further improvement.
[utility model content]
The purpose of this utility model provides a kind of electric connector, be convenient to tool to the even application of force of insulating body to remove this insulating body from printed circuit board (PCB).
To achieve these goals, the utility model adopts following technological means: a kind of electric connector, be used to electrically connect the chip module to printed circuit board (PCB), it comprises insulating body and conducting terminal, insulating body comprises flat diapire and extends the sidewall of setting from diapire, diapire and sidewall are formed a receiving space and are used to accommodate the chip module, diapire comprises the upper bottom surface of accepting the chip module and the bottom surface that is mounted to printed circuit board (PCB), sidewall comprises madial wall and the corresponding lateral wall that closes on receiving space, bottom surface is provided with the groove that runs through lateral wall, the hook portion of itself and tool setting interlocks and holds, by the even application of force, and then reach the purpose that removes insulating body from printed circuit board (PCB) to tool.
Compared with prior art, the utlity model has following advantage: by run through the groove of lateral wall in the setting of insulating body bottom surface, it can interlock with the hook portion of tool setting and hold, by the even application of force to tool, to reach the purpose that removes insulating body from printed circuit board (PCB).

Fig. 2 is the stereogram of the utility model electric connector insulating body.
Fig. 3 is the utility model electric connector and tool assembling and the stereogram that is assembled to printed circuit board (PCB).
Fig. 4 is the enlarged drawing of the local A of stereogram shown in Figure 3.
[embodiment]
As shown in Figure 1, 2, be the utility model electric connector one most preferred embodiment, it is used to electrically connect chip module (not shown) to printed circuit board (PCB) 3, comprises insulating body 1 and conducting terminal 2.
Shown in Fig. 3,4, insulating body 1 is assembled to after the printed circuit board (PCB) 3, bottom surface 132 closely cooperates with printed circuit board (PCB) 3, the tool 4 that is used to help to remove insulating body 1 is provided with hook portion 41, it can interlock with groove 1322 and hold, by tool 4 being applied a strength that makes progress, can remove insulating body 1 from printed circuit board (PCB) 3 easily.
The utility model emphasis structure is: insulating body bottom surface 132 is provided with the groove 1322 that runs through lateral wall 122, it can interlock with the hook portion 41 that tool 4 is provided with and hold, by the even application of force to tool 4, and then can remove insulating body 1 from printed circuit board (PCB) 3 easily, in the present embodiment, the diagonal position place that is arranged at bottom surface 132 of groove 1322 symmetries, this does not constitute any restriction to the utility model, groove 1322 also can be arranged on other optional positions of insulating body bottom surface 132 as required, all can reach the hook portion 41 that is provided with tool 4 and interlock and hold conveniently to remove the purpose of insulating body 1.
The above only is a kind of execution mode of the present utility model, it or not whole or unique execution mode, the variation of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model specification is claim of the present utility model and contains.
Claims (3)
