Wherein positioning insertion pin is connected with base, and the structure employing moulding due to module, has caused device and PCB(printed circuit board) imperfect earth.While therefore installing in some areas, usually occur that module is because antistatic property is not good, the situation that causes module optical assembly to damage.

Because the structural framing adopting is at present relatively fixing, very limited at the front end spaces of module, very difficult when doing static release.

Summary of the invention

The utility model, for the problems referred to above, provides a kind of optical module, forms a static and discharge approach on this optical module, reaches the effect of protection optical assembly and internal circuit, thereby improves the antistatic property of module.

According to the technical solution of the utility model: a kind of optical module, it is characterized in that: comprise base, the link broad ways of described base is provided with two mounting grooves, between two mounting grooves, be provided with block button hole, described in each, in mounting groove, be equipped with a connector, on mounting groove back step face, be provided with shell fragment, the deep-slotted chip breaker of described shell fragment is corresponding with base plate through holes, contact pin is arranged in described through hole, and described contact pin top stopper is supported in shell fragment deep-slotted chip breaker upper surface, contact pin bottom passes from base, described base upper cover closes and is provided with upper cover, contact pin is fixed by the projection above covering.

As further improvement of the utility model, on described base, be laid with radiating groove, and be provided with some row's pin holes between the radiating groove of base and the blind end of base.Blind end and the dual-side of described base are equipped with buckle slot, above cover and are provided with the buckle matching with described buckle slot.The diameter of the stopper of described contact pin is greater than the diameter of through hole.The link of described base is formed with respectively arcwall face corresponding to the both sides of mounting groove.

Technique effect of the present utility model is: the utility model product is by carrying out technological improvement to the deficiency of existing product; rear positions place corresponding to connector on base is reserved with certain space; be used for preventing conducting strip; outside static is drawn to module by the contact pin pin of module; thereby form a static and discharge approach; reach the effect of protection optical assembly and internal circuit, thereby improve the antistatic property of module.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.

In Fig. 1 ~ 6, comprise upper cover 1, base 2, contact pin 3, shell fragment 4, connector 5, radiating groove 6, row's pin hole 7, link 8, blind end 9, mounting groove 10, block button hole 11, through hole 12, buckle 13, buckle slot 14, projection 15 etc.

As shown in Fig. 1 ~ 3, the utility model is a kind of optical module, comprise base 2, link 8 broad ways of described base 2 are provided with two mounting grooves 10, between two mounting grooves 10, be provided with block button hole 11, described in each, in mounting groove 10, be equipped with a connector 5, on mounting groove 10 back step faces, be provided with shell fragment 4, the deep-slotted chip breaker of described shell fragment 4 is corresponding with base 2 through holes 12, contact pin 3 is arranged in described through hole 12, and described contact pin 3 top stoppers are supported in shell fragment 4 deep-slotted chip breaker upper surfaces, contact pin 3 bottoms pass from base 2, on described base 2, cover and be provided with upper cover 1, contact pin 3 is fixed by the projection 15 on upper cover 1.

As shown in Figure 2, on described base 2, be laid with radiating groove 6, and be provided with some row's pin holes 7 between the radiating groove 6 of base 2 and the blind end 9 of base 2, the linearly layout of row's pin hole 7.

As shown in Figure 2,3, blind end 9 and the dual-side of described base 2 are equipped with buckle slot 14, and upper cover 1 is provided with the buckle 13 matching with described buckle slot 14; .

As shown in Figure 6, the diameter of the stopper of described contact pin 3 is greater than the diameter of through hole 12, by the stopper of contact pin 3, guarantees that contact pin 3 can landing from through hole 12.

The link 8 of described base 2 is formed with respectively arcwall face corresponding to the both sides of mounting groove 10.

As shown in Figure 5, on shell fragment 4, be formed with deep-slotted chip breaker, when shell fragment 4 is arranged on base 2, the notch of deep-slotted chip breaker is corresponding to through hole 12 upper end open places.

As shown in Figure 4, the link of connector 5, with flange, when connector 5 is connected on base 2, is placed in mounting groove 10 by the flange of connector 5, can connector 5 is effectively fixing.
