Description

Electric connector

[technical field]

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

[background technology]

Existing wafer module need be provided with electric connector with the electric connection of printed circuit board (PCB), and the wafer module that needs to be electrically connected with this electric connector pushes down appositely, and this wafer module is stably fixed.

As shown in Figure 1, existing electric connector generally comprise insulating body (not shown), be contained in insulating body plurality of conductive terminals (not shown), be located at the reinforcement 3 in the insulating body outside ', be articulated in the pressing plate 4 of reinforcement 3 ' opposite end ' and driving lever 5 '.This electric connector is positioned on the circuit board, on the conducting terminal of the insulating body upper surface of wafer module 2 ' be positioned over electric connector, by conducting terminal realize circuit board and wafer module 2 ' between electric connection.

Pressing plate 4 ' be a hollow framework, its opposite end be respectively articulate reinforcement 3 ' first end 41 ' and with second end 42 of driving lever 5 ' fastening '.Pressing plate 4 ' the outward extending hook portion 43 of first end 41 ' be arranged with '.Pressing plate 4 ' second end, 42 ' middle part be provided with forward the auxiliary section 44 of convergent bending extension '.Connect pressing plate 4 ' first end 41 ' and second end 42 ' the limit, two opposite sides the centre position to the insulating body direction convex to form press section 45 '.

Pressing plate 4 ' with two hook portions 43 ' be held in reinforcement 3 ' two relative buttons hold hole 31 ' in, make pressing plate 4 ' can with reinforcement 3 ' button hold hole 31 ' be that rotating shaft is opened or closure.Driving lever 5 ' be articulated in reinforcement 3 ' articulated section (not label) in, driving lever 5 ' a have protuberance 51 ', when pressing plate 4 ' when being fastened on the insulating body, driving lever 5 ' protuberance 51 ' press on pressing plate 4 ' auxiliary section 44 ' on, by pressing plate 4 ', driving lever 5 ' with reinforcement 3 ' pivot joint with cooperate, can be with wafer module 2 ' be fixed in the insulating body, again because press section 45 ' press on wafer module 2 ' on, thereby can realize wafer module 2 ' with the stable electric connection of electric connector.

This electric connector is behind the wafer module 2 ' be assembled into electric connector, require pressing plate 4 ' upper surface must be no more than wafer module 2 ' upper surface.Yet; when pressing plate 4 ' relatively to the press section 45 of dual-side ' press on wafer module 2 ' when going up; because wafer module 2 ' to press section 45 ' have reaction force; so; when driving lever 5 ' with pressing plate 4 ' fastening after; pressing plate 4 ' with an end of driving lever 5 ' fastening can be higher than usually wafer module 2 ' upper surface, consult shown in Figure 2ly, dotted line is the horizontal line of wafer module 2 ' upper surface among the figure.This kind design than higher, is difficult to control to the requirement of electric connector.In addition, pressing plate 4 ' also may the produce press section 45 ' problem protruding upward of relative both sides, so also can make the highest place of pressing plate surpass wafer module 2 ' the highest, cause wafer module 2 ' can not closely contact with heat abstractor, cause the not enough problem of heat radiation.

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]

The technical problem that the utility model solved provides a kind of electric connector that can guarantee that wafer module and heat abstractor well contact and dispel the heat.

For solving the problems of the technologies described above, the utility model provides a kind of electric connector, be used to electrically connect the wafer module to printed circuit board (PCB), the reinforcement that it comprises insulating body, be contained in plurality of conductive terminals in the insulating body, establish with the insulating body group, can oppress the pressing plate and that the wafer module electrically connects wafer module and conducting terminal and detain the fixture of holding pressing plate; Described pressing plate is the hollow framework, and wherein, the relative dual-side of pressing plate framework extends in framework and is provided with the press section, and described press section is to the direction projection away from insulating body.

Compared with prior art, the utlity model has following advantage: extend in framework and to the direction projection away from insulating body the press section, because upwards raise the press section, so after the assembling of wafer module, the upper surface of wafer module is higher than the height of pressing plate peak, this design is than being easier to satisfy the upper surface that peak that electric connector fastens rear fender is lower than the wafer module, heat abstractor just can closely contact with the upper surface of wafer module like this, can not cause the not enough problem of heat radiation.
