Description

Electric coupler component

[technical field]

The utility model relates to a kind of electric coupler component, relates in particular to a kind of electric coupler component that is electrically connected to printed circuit board (PCB).

[background technology]

Because the present high speed data transfer of computer and because of job requirements, the operating time of computer is also more and more longer, and correspondingly the heat that central processing unit produced is increasing, is necessary to use heat abstractor, the heat that produces when leaving computer operation.When being installed on heat abstractor on the printed circuit board (PCB), because the weight that printed circuit board (PCB) is difficult to bear radiator generally increases the intensity that a backboard is strengthened printed circuit board (PCB).At present, industry backboard commonly used generally has two kinds, and a kind of is the backboard of using plastic shaping, another kind is with metal stamping formed backboard, and is simple with the backboard manufacturing of plastic shaping, and cost is lower, but in use its intensity is restricted, and can't reach required intensity sometimes.Be illustrated in figure 1 as a kind of existing electric coupler component 100 ', it comprises and is used to electrically connect electric connector 1 ' and the metal backing 4 ' of chip module 5 ' to printed circuit board (PCB) 3 '.Metal backing 4 ' has higher intensity, can satisfy the demand of intensity, but needs the insulation effect between assurance metal backing 4 ' and the printed circuit board (PCB) 3 '.At present, a kind of existing technology is by pasting a kind of soft insulating trip (not shown) at backboard 4 ' upper surface.

Yet this kind insulating trip does not have location feature, utilizes viscose glue to fit again, therefore paste easily askew, produce phenomenons such as fold and bubble, therefore comparatively difficult in the assembling.

Therefore, be necessary to design a kind of new electric coupler component to overcome above-mentioned shortcoming.

[utility model content]

The purpose of this utility model is to provide a kind of electric coupler component, can reach good insulation performance effect and easy to assembly between its metal backing and the printed circuit board (PCB).

For achieving the above object, the utility model adopts following technical scheme: a kind of electric coupler component, comprise electric connector and metal backing, wherein the electric connector top that is fixed to printed circuit board (PCB) is used to electrically connect chip module and printed circuit board (PCB), metal backing is assembled to the below of printed circuit board (PCB), be provided with the insulation sheet between itself and the printed circuit board (PCB), it is provided with trip and fastens to metal backing.

Compared to prior art, the insulation sheet can reach the good insulation performance effect in the utility model electric coupler component, and can fasten to metal backing by trip, easily assembling and inaccurate problem can not occur locating.

[embodiment]

Shown in Fig. 2,3,4, the utility model electric coupler component 100 comprises electric connector 1, metal backing 5 and insulation sheet 4.

Electric connector 1 is installed in the top of printed circuit board (PCB) 3, is used to electrically connect chip module 6 to printed circuit board (PCB) 3, and it is provided with some installing holes 11, and correspondence is provided with some circular holes 31 on the printed circuit board (PCB) 3.

The plate-like structure that metal backing 5 forms for punching press, the below that is installed in printed circuit board (PCB) 3 is used to strengthen the intensity of printed circuit board (PCB) 3, and the circular hole 31 on its corresponding printed circuit board (PCB) 3 is provided with assembly hole 51.

Insulation sheet 4 is located between metal backing 5 and the printed circuit board (PCB) 4, it is for plate-like structure and be slightly larger than metal backing 5, trip 42 is extended on insulation sheet 4 four limits, in the present embodiment, insulation sheet 4 four limits are respectively extended a trip 42 and are fastened four limits to metal backing 5, please consult shown in Figure 3ly simultaneously, and trip 42 is provided with lead-in chamfered 421, when being assembled to metal backing 5, make assembling more convenient.Circular hole on the insulation sheet 4 corresponding printed circuit board (PCB)s 3 is provided with location hole 41.

The utility model is to pass through fixture, as screw 2, pass location hole 41 on installing hole 11 on the electric connector 1, the circular hole 31 on the printed circuit board (PCB) 3, the insulation sheet 4 and the assembly hole 51 on the metal backing 5, according to this electric connector 1, insulation sheet 4 and metal backing 5 firm be assembled to printed circuit board (PCB) 3.

The utility model emphasis structure is: an insulation sheet 4 is set between metal backing 5 and printed circuit board (PCB) 3, and it is provided with trip 42 and fastens to metal backing 5, makes and realizes good insulation performance effect and easy to assembly between metal backing 5 and the printed circuit board (PCB) 3.

Should be understood that, 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.
