Description

A kind of side compression type grounding elastic part

Technical field

The utility model relates to grounding elastic part technical field, is specifically related to a kind of side compression type grounding elastic part.

Background technology

Grounding elastic part is current electronic information sector application element very widely, for the conducting ground connection of circuit board and metal shell, makes electronic component reach the object of release electrostatic.

But, existing grounding elastic part also exists defect, because limited by product design and physical dimension, conventionally the grounding elastic part of production and application can not be realized the circuit board of vertical assembling and the elasticity ground connection between metal-back dignity flexibly, often need the more complicated grounding elastic part of design, first by riveted joint or screw, fix on metal shell, then compress and contact conducting with the formation of circuit board face, and cannot realize by product size restriction.In addition, existing ground lug structure size is larger and complicated, and after ground strip and outer shell rivething, commonality is also poor, as the mode that is screwed takes up space and process costs is higher.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of side compression type grounding elastic part for above-mentioned the deficiencies in the prior art, make to pass through side compression type elasticity ground connection between the vertical circuit board assembling and metal-back dignity, make electronic component reach the object of effective release electrostatic.

The utility model is to address the above problem adopted technical scheme to be: a kind of side compression type grounding elastic part, the middle U-shaped shell fragment and two the symmetrical outside shell fragments that comprise one bending forming, described two outside shell fragments comprise the first shell fragment of two end face outwards that engage respectively middle U-shaped shell fragment and engage the second shell fragment that the first shell fragment bends inwards, the bending junction surface of described the first shell fragment and the second shell fragment is formed for the first abutting part of butt metal shell, and the end of described the second shell fragment is provided with for clamping the second abutting part of butt circuit board.

Further, on the inwall of two sidepiece shell fragments of described middle U-shaped shell fragment, be respectively provided with positioning boss, for fastening with the location hole of circuit board two sides setting.

Further, the stopper slot that the bottom shell fragment of described middle U-shaped shell fragment arranges for inserting circuit board side.

The beneficial effects of the utility model are:

The side compression type grounding elastic part that the utility model provides can be realized the circuit board of vertical assembling and the elasticity ground connection between metal-back dignity flexibly, effect of structural dimension to product main body is little, and in use only need simple spiral-lock on circuit board, utilize the thrust of shell fragment conduction to contact with circuit board positive and negative, do not need welding or screw to be fixed on wiring board, also need not rigidly fix with metal shell, commonality is good, cost-saving.

Embodiment

Below in conjunction with accompanying drawing, specifically illustrate execution mode of the present utility model, accompanying drawing is only for reference and use is described, does not form the restriction to the utility model scope of patent protection.

As shown in Figure 1, the present embodiment provides a kind of side compression type grounding elastic part 1, the middle U-shaped shell fragment 10 and two the symmetrical outside shell fragments 11 that comprise one bending forming, described two outside shell fragments 11 comprise the first shell fragment 111 of two end face outwards that engage respectively middle U-shaped shell fragment 10 and engage the second shell fragment 112 that the first shell fragment 111 bends inwards, the bending junction surface of described the first shell fragment 111 and the second shell fragment 112 is formed for the first abutting part 12 of butt metal shell 3, the end of described the second shell fragment 112 is provided with for clamping the second abutting part 13 of butt circuit board 2.

As shown in Figure 2,3, in the present embodiment, in the middle of described, on the inwall of two sidepiece shell fragments of U-shaped shell fragment 10, be respectively provided with positioning boss 14, for fastening with the location hole 21 of circuit board 2 two sides settings, the stopper slot 22 that the bottom shell fragment of described middle U-shaped shell fragment 10 arranges for inserting circuit board 2 sides.

Fig. 2 and Fig. 3 are the assembling process schematic diagram of this side compression type grounding elastic part 1 and circuit board 2, grounding elastic part 1 inserts in the stopper slot 22 of circuit board 2 sides settings by the bottom shell fragment of middle U-shaped shell fragment 10, the positioning boss 13 of grounding elastic part 1 snaps in 21 pairs of grounding elastic parts of location hole 1 and carries out spacingly, and the second abutting part 13 of described grounding elastic part 1 and circuit board 2 positive and negatives form and contact and clamp.
