Abstract
The invention provides a pull rivet nut for reliable electrical ground, comprising a pull rivet nut, a nut polished rod and a compression ring, wherein the press joining surface of the pull rivet nut and the annular surface of the compression ring are respectively provided with a protrusion; when the coating sheet metal of a power distribution switch equipment shell is assembled with a pull rivet, the protrusion on the press joining surface of the pull rivet nut and the protrusion on the annular surface of the compression ring are respectively penetrated into the sheet metal so as to destroy the coating on the sheet metal surface, thus the pull rivet nut and the compression ring respectively and directly contact with a sheet metal substrate to realize the reliable ground, thereby having the advantages of simple process, fastness and convenience, good safety performance, and obvious grounding effect.
Description
Technical field
The present invention relates to staking nut external member, particularly a kind of staking nut external member that is used for reliable electric ground connection.
Background technique
How the shell of current distribution switchgear is assembled with the coating metal plate of 2mm～3mm, in order to replace traditional welded nut, it is meltable to remedy the welding of sheetmetal, light wall pipe, deficiencies such as welded nut location difficulty, and staking nut commonly used is fastening with the metal-sheet parts of shell in factory's assembling.
According to GB3906-2006 " 3.6KV～4.05KV ac metal closing switch gear and control apparatus " and GB/T7251.1～5-2005 " low-voltage complete switch equipment and control apparatus " regulation, the distribution switchgear shell is the part of ground connection, requirement has reliable ground connection, to guarantee personal safety.But all there is coating on the metal sheet surface of current distribution switchgear shell, the insulating properties of coating has influenced the electrical continuity of distribution switchgear, for head it off, guarantee the electrical continuity of distribution switchgear, before staking, all can do coating removal and handle usually the outer cover metal plate surface of need staking position, though solved the electrical continuity of distribution switchgear ground connection like this, but increase factory's assembly process, reduced working efficiency, and reliability is not high.
Summary of the invention
The present invention is in order to overcome above the deficiencies in the prior art, and a kind of rational in infrastructure, ground connection reliability height, high working efficiency, staking nut external member that Security is good are provided.
Purpose of the present invention realizes by following technological scheme: a kind of staking nut external member that is used for reliable electric ground connection, comprise staking nut, nut polished rod part and pressure ring, and be respectively arranged with point on the crimping face of described staking nut and the ring surface of pressure ring and dash forward.
It is prominent to be respectively arranged with point on the crimping face of described staking nut and the ring surface of pressure ring, when staking, pneumatic or manual hand riveter can order about nut polished rod part stress deformation and the coating metal plate and the pressure ring riveting of staking nut and distribution switchgear shell is integral, at this moment, the point of staking nut crimping face is prominent can to thrust metal sheet, destroys the coating of plate surface; The prominent another side that can thrust metal sheet of point on the pressure ring ring surface punctures coating, and like this, staking nut, pressure ring can contact with the metallic matrix of metal sheet respectively, guarantee the electrical continuity of distribution switchgear, realize reliable electrical grounding.
Described point is prominent to be helped sharp bur and goes into metal sheet for pyramid-shaped or flexuose, contacts with metallic matrix.
The prominent quantity of described point is 3～6, has guaranteed the sharp prominent reliability that can thrust metal sheet.
Described point is prominent be evenly distributed on the staking nut crimping face circumference and the ring surface of pressure ring on, point is dashed forward to thrust metal sheet from all directions, improve the validity that staking nut, pressure ring contact with the metallic matrix of metal sheet respectively, guaranteed the electrical continuity of distribution switchgear.
As optimal technical scheme, the point on the described staking nut crimping face prominent with the pressure ring ring surface on the prominent mutual dislocation of point.
The present invention has following advantage with respect to prior art:
A kind of staking nut external member that is used for reliable electric ground connection of the present invention, when distribution switchgear coating metal plate shell assembling staking, dash forward and puncture the metal sheet coating by point is set respectively on the ring surface of the crimping face of staking nut and pressure ring, staking nut, pressure ring directly can be contacted with the sheet metal matrix respectively reach the reliable ground purpose, and do not need independent sheet material to carry out carrying out the staking connection after the processing to band coating, very convenient quick, operation is simple, Safety performance is good, and the ground connection effect is obvious.
Description of drawings
Fig. 1 is a kind of structural drawing that is used for the staking nut external member of reliable electric ground connection of the present invention.
Fig. 2 is a kind of staking nut external member of reliable electric ground connection and structural representation after the metal sheet riveted joint of being used for of the present invention.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.But embodiments of the present invention are not limited thereto.
1-staking nut, 2-nut polished rod part, the 3-point is prominent, 4-pressure ring, 5-coating, 6-metal sheet
Specific embodiment
As Fig. 1, shown in Figure 2, a kind of staking nut external member that is used for reliable electric ground connection, comprise staking nut 1, nut polished rod part 2 and pressure ring 4, be respectively arranged with point prominent 3 on the ring surface of the crimping face of staking nut 1 and pressure ring 4, point prominent 3 is a pyramid-shaped, help point prominent 3 and thrust metal sheet 6, contact with metallic matrix, point prominent 3 be evenly distributed on the staking nut 1 crimping face circumference and the ring surface of pressure ring 4 on, make point prominent 3 thrust metal sheet 6 from all directions, improved staking nut 1, the validity that pressure ring 4 contacts with the metallic matrix of metal sheet 6 has respectively guaranteed the electrical continuity of distribution switchgear.
When staking, pneumatic or manual hand riveter can order about nut polished rod part 2 stress deformations and coating 5 metal sheets 6 and pressure ring 4 rivetings of staking nut 1 with the distribution switchgear shell are integral, at this moment, the point of staking nut 1 crimping face prominent 3 can thrust metal sheet 6, destroys the coating 5 of plate surface; Point on pressure ring 4 ring surfaces prominent 3 can thrust the another side of metal sheet 6, punctures coating 5, and like this, staking nut 1, pressure ring 4 can contact with the metallic matrix of metal sheet 6 respectively, guarantee the electrical continuity of distribution switchgear, realize reliable electrical grounding.
Above-mentioned embodiment is the preferred embodiments of the present invention; can not limit claim of the present invention; other any change or other equivalent substitute mode that does not deviate from technological scheme of the present invention and made is included within protection scope of the present invention.
