Abstract

The utility model discloses a grounding device of an electrical equipment built-in card interface element. The utility model comprises a damper and an interface element provided on the built-in card. A shrapnel which can touch the interface element is provided on the side face which faces the card. The shrapnel can be designed with different shapes according to the specific interface element. Different connecting positions can be chosen so as to meet the requirements of the interface element which has different shapes and positions. The tight contact between the shrapnel and the interface element which has been made sure ensures the interface element reliable grounding. Thus the electromagnetic radiation of in the crate e which can be leaked out of the crate through the interface part can be effectively prevented and then the interference to another electrical equipment can be reduced. The shrapnel which has simple structure and is easy to be assembled can extend the choosing range of the interface element so the product cost is lowered.

Description

The earthing device of built-in integrated circuit board interface element

Technical field

The utility model relates to the earthing device of the built-in integrated circuit board interface element of a kind of electric equipment.

Background technology

The interface element of the built-in integrated circuit board of electric equipment and cabinet keep reliable ground, and solve the EMI problem effectively, must select the interface element that itself has grounding elastic part for use.Even since at present a lot of interface elements shell fragment is not set or have shell fragment also because be subjected to component placement restriction, element to carry the limitation of shell fragment shape or size and other influence, cause the interface element can't reliable ground, also be difficult to effectively solve the EMI problem.

Summary of the invention

The utility model will solve the interface element of the built-in integrated circuit board of electric equipment and the technical problem that cabinet keeps reliable ground, proposes a kind of earthing device that can effectively overcome the EMI problem.

Technical solution of the present utility model is to adopt a kind of earthing device of built-in integrated circuit board interface element, comprises baffle plate, places the interface element on the built-in integrated circuit board, on described baffle plate and the side that integrated circuit board links to each other, is provided with the shell fragment that can contact with described interface element.

Described shell fragment comprises joint face and the tongue that has angle and link to each other with joint face.

The material of described shell fragment is a stainless steel, and material thickness is 0.1 to 0.2 millimeter.

Described shell fragment and baffle plate be connected to riveted joint.

The utility model can design difform shell fragment according to specific interface element, select different link positions, to adapt to the requirement of interface element difformity, position, guarantee that shell fragment contacts with the tight of interface element, to guarantee the reliable ground of interface element.So can effectively stop the interior electromagnetic radiation of cabinet to leak into outside the cabinet, reduce its interference other electrical equipment by the interface position.Elastic piece structure is simple, directly be connected on the baffle plate, assembling easily, expansion interface selection of components scope widely is so that reduce the cost of product.

Embodiment

Be illustrated in figure 1 as an embodiment of the present utility model, the earthing device of the built-in integrated circuit board interface element of a kind of computer, comprise baffle plate 1, place the interface element tuner 2 on the built-in integrated circuit board of PCB, on the side 8 that baffle plate 1 links to each other with integrated circuit board, be provided with the shell fragment 3 that can contact with tuner 2.As Fig. 4, shown in 5, this shell fragment 3 can be a rectangle stainless steel substrates, its thickness is 0.1 to 0.2 millimeter, go out a shape of a hoof 10 in the punching of the middle part of this shell fragment 3, link to each other but the straight flange of the shape of a hoof 10 is parallel with shell fragment 3 one sides, the shape of a hoof 10 remaining arc limit are all cut off, the part that goes out that is gone out by punching keeps rectangle part 11 as required, with the outside bending of the free end of this rectangle part, the tongue 5 that the joint face 4 of formation and shell fragment 3 has angle, the middle part of tongue has rectangular opening 6, in order to reduce its rigidity, increase its elasticity, can go out fillet surface 7, so that keep good contact with the shell of interface element tuner in the free end bending of tongue 5.

Shown in Fig. 6,7,8, the joint face 4 of shell fragment 3 is riveted on the middle part of baffle plate 1, the shape of a hoof hole 10 that makes shell fragment 3 coincides with the hole 9 of baffle plate 1, and makes tongue 5 point to baffle plates 1 installation folding 12.Shell fragment 3 can be according to the different layout adjustment of interface element 2 with the link position of baffle plate 1, and shell fragment 3 can also be that screw connects or welding with being connected of baffle plate 1.As shown in Figure 1, the flanging 12 and the integrated circuit board screw of shell fragment 3 is connected in 13, tongue 5 is pressed on the shell 14 of interface end of tuner 2, and the interface end 14 of tuner 2 passes from the hole 9 of baffle plate 1, and the open pore 15 of baffle plate 1 is connected with the cabinet screw.Because tongue 5 is pressed on the shell 14 of tuner 2 interface end tightly, so can effectively stop the interior electromagnetic radiation of cabinet to leak into outside the cabinet by the interface position, reduce its interference to other electrical equipment.
