Abstract
The utility model particularly relates to a gasket capable of penetrating an insulating layer on the surface of a shell, which belongs to the technical field of locking of screws, bolts or nuts. The gasket is capable of penetrating the insulating layer on the surface of the shell and has reliable electric conduction, simple structure and strong applicability. The gasket comprises a metallic flat gasket; the structural key points of the gasket are that a cone-shaped bulge is arranged on the upper surface of the flat gasket; and a strip-shaped dent is arranged on the lower surface of the flat gasket.
Description
Technical field
The utility model is divided by International Patent Classification (IPC) (IPC) and is belonged to mechanical engineering, illumination, heating, weapon, explosion portion, engineering element or parts; For producing and keep the general measure of effective operation of machine or equipment; General adiabatic big class, the device that fastening or fixed component or machine parts are used is as nail, bolt, circlip, folder, clip, wedge; Connector or connection group, screw, the locking technical group field of bolt or nut relates in particular to a kind of packing ring that stings the surface of shell insulating barrier.
Background technology
In high-low pressure power equipment switch cubicle, there is the surface of shell of a lot of switch cubicles to spray paint or plastic-blasting, part such as the mounting rail of switch cubicle and whole cabinet must continuous grounds according to the switch cubicle standard-required, in order to improve the safe handling of equipment.Since surface of shell sprays paint or parts such as plastic-blasting and metal mounting rail between be connected the requirement that can not reach grounded continuous with the structure of normal screws, bullet pad, plain cushion and nut type, for meeting the demands, before surface of shell surface lacquer or plastic-blasting, must be welded with special grounding screw, along with increasing of mounting rail, the double-screw bolt of welding also must increase, and has so just increased the complexity of the processing technology of product, waste man-hour again, increase cost.
Summary of the invention
The utility model is exactly at the problems referred to above, and a kind of packing ring that stings the surface of shell insulating barrier reliable, simple in structure, that applicability is strong that conducts electricity is provided.
For achieving the above object, the utility model adopts following technical scheme, and the utility model comprises metallic flat gasket, and the upper surface of its structural feature plain washer is provided with cone-shaped bulge, and the lower surface of plain washer is provided with the strip depression.
As a kind of preferred version, cone-shaped bulge described in the utility model is at least two, and is distributed on the upper surface of plain washer.
As another kind of preferred version, strip depression described in the utility model is at least two, and is distributed in the lower surface of plain washer.
In addition, the extended line of strip depression described in the utility model is by the center of plain washer.
The utility model beneficial effect: (1) product quality height, safe and reliable.Because the upper surface of the utility model plain washer is provided with cone-shaped bulge, when fastening, cone-shaped bulge and surface of shell have and spray paint or the face of plastic-blasting contacts, through fastening, cone-shaped bulge will suffer oppression and sting surface of shell lacquer painting and with intact contact of metal part of enclosure interior, finish the favorable conductive continuity.And the lower surface of the utility model plain washer is provided with the strip depression, when connecting, can prevent to become flexible, and increases the frictional resistance of plain washer and bullet pad or nut, makes the conduction continuity of entire equipment can reach standard-required fully.
(2) easy to use, the efficient height.Because the utility model is simple in structure, has reduced man-hour greatly in machining process, has dwindled cost, has improved production efficiency.
(3) applicability is strong.In any power equipment that has than thin dielectric layer, can both reach desirable conduction requirement by using the utility model.
Description of drawings
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with the drawings and the specific embodiments, the utility model is further elaborated.Should be appreciated that embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 1 is the utility model package assembly schematic diagram.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the rearview of Fig. 1.
Fig. 4 is that the utility model uses the assembling schematic diagram.
For plain washer, 2 for the taper projection, 3 for strip depression, 4 for nut, 5 for play packing ring, 6 for common plain washer, 7 for the metal mounting rail, 8 for the housing, 9 that has insulating barrier be bolt.
Embodiment
As shown in the figure, the utility model comprises metallic flat gasket 1, and the upper surface of plain washer 1 is provided with cone-shaped bulge 2, and the lower surface of plain washer 1 is provided with strip depression 3.
Described cone-shaped bulge 2 is at least two, and is distributed on the upper surface of plain washer 1; Sting better effects if, the conduction more reliable.
Described strip depression 3 is at least two, and is distributed in the lower surface of plain washer 1.
The extended line of described strip depression 3 is by the center of plain washer 1; Friction effect is better.
Use below in conjunction with description of drawings patent of the present invention: at first select corresponding bolt 9, common plain washer 6, play packing ring 5, the housing 8 that has insulating barrier, metal mounting rail 7, nut 4.Bolt 9 successively passes common plain washer 6, metal mounting rail 7, the housing 8 that has insulating barrier, the utility model, bullet packing ring 5, nut 4, with spanner nut 4 is tightened, this moment, cone-shaped bulge 2 of the present utility model destroyed the insulating barrier of housing, and contact fully with interior metal, reach the successional requirement of conduction.
Above content is to further describing that the utility model is done in conjunction with concrete preferred implementation; can not assert that concrete enforcement of the present utility model is confined to these explanations; for the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design; can also make some simple deduction or replace, all should be considered as belonging to the definite protection range of claims that the utility model is submitted to.
