Abstract
The utility model provides a bolt assembly for connecting busway shell body, including connecting bolt, spring shim and ground connection gasket, connecting bolt includes bolt head and threaded rod, and spring shim and ground connection gasket connect gradually the downside at the bolt head, and the edge of ground connection gasket lower extreme face is provided with corner pad, and corner pad's sharp -pointed portion is towards the threaded rod lower extreme. The beneficial effects are that can realize that corner pad's sharp -pointed portion pricks the casing patent leather through compressing tightly the connection busway shell body, play the effect of electrically conductive continuity protection and fastening, the bolt effectively prevents the bolt because electromagnetic induction is the electrified contact personnel that shock by electricity with the conductive contact of casing, prevents to become flexible after tightening.
Description
Technical field
This utility model belongs to bus duct fastening connection piece field, especially relates to a kind of bolt assembly for connecting bus groove case.
Background technology
Bus duct joins power transmission system for low pressure, the fastening bolt of bus groove case is all that ferromagnetic material manufactures, toroidal magnetic field can be formed around conductor during bus duct inner conductor stream super-high-current, the bolt of rugged housing is by the effect meeting induction charging in magnetic field, personnel for contacting bus duct can cause electric shock, produces harm.This assembling bolt is by the coat of paint of the broken bus groove case of ground connection cushion Fructus Gleditsia acupuncture, and coat of paint belongs to megohmite insulant, makes bolt and casing metal be conductively connected reliably, the electricity of bolt sensing is discharged to ground by housing, reaches conducting continuity safeguard protection effect.
Utility model content
In view of this; this utility model is directed to a kind of bolt assembly for connecting bus groove case; the sharp-pointed portion that can realize pad angle by compressing connection bus groove case punctures housing coat of paint; play the effect of conducting continuity protection and fastening; the conductive contact of bolt and housing effectively prevents bolt because the charged electric shock exposure personnel of electromagnetic induction, prevents from loosening after tightening.
For reaching above-mentioned purpose, the technical solution of the utility model is achieved in that
A kind of bolt assembly for connecting bus groove case, including connecting bolt, spring shim and ground pad, described connecting bolt includes bolt head and threaded rod, described spring shim and described ground pad are connected to the downside of described bolt head in turn, the edge of described ground pad lower surface is provided with pad angle, and the sharp-pointed portion at described pad angle is towards described threaded rod lower end.
Further, the outer surface of described connecting bolt, described spring shim and described ground pad is coated with one layer of zinc rete.
Further, described bolt head is regular hexagon.
Further, described bolt head upper surface is provided with criss-cross twist-on groove.
Relative to prior art, the bolt assembly for connecting bus groove case described in the utility model has the advantage that
Connecting bolt can corresponding twist-on in the connecting hole of bus groove case, ground pad is against on connecting hole, along with the threaded rod of connecting bolt is screwed into gradually, the sharp-pointed portion at the pad angle of ground pad lower surface edge can puncture the coat of paint of bus groove case, the effect of stop is played in the sharp-pointed portion at pad angle, play the effect of conducting continuity protection and fastening, the overall conductive contact with housing of this utility model, effectively prevent because of the charged electric shock exposure personnel of electromagnetic induction, effectively prevent conductor from producing mechanical vibration because of electric power, effectively reduce noise and vibration, it is completely embedded, prevent from after tightening loosening；The zinc rete that the outer surface of connecting bolt, spring shim and ground pad is coated with, it is possible to play the effect preventing corrosion.
Accompanying drawing explanation
The accompanying drawing constituting a part of the present utility model is further appreciated by of the present utility model for providing, and schematic description and description of the present utility model is used for explaining this utility model, is not intended that improper restriction of the present utility model.In the accompanying drawings:

Fig. 2 is plan structure schematic diagram of the present utility model.
Description of reference numerals:
1-connecting bolt；11-bolt head；111-twist-on groove；12-threaded rod；2-spring shim；3-ground pad；31-pad angle；The sharp-pointed portion of 32-.
Detailed description of the invention
It should be noted that when not conflicting, the embodiment in this utility model and the feature in embodiment can be mutually combined.
In description of the present utility model, it will be appreciated that, term " " center ", " longitudinal direction ", " transverse direction ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, it is for only for ease of description this utility model and simplifies description, rather than the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.
In description of the present utility model, it is necessary to explanation, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, for instance, it is possible to it is fixing connection, it is also possible to be removably connect, or connect integratedly；Can be mechanically connected, it is also possible to be electrical connection；Can be joined directly together, it is also possible to be indirectly connected to by intermediary, it is possible to be the connection of two element internals.For the ordinary skill in the art, it is possible to understand above-mentioned term concrete meaning in this utility model by concrete condition.
Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As shown in Figure 1, 2, this utility model provides a kind of bolt assembly for connecting bus groove case, including connecting bolt 1, spring shim 2 and ground pad 3, described connecting bolt 1 includes bolt head 11 and threaded rod 12, described spring shim 2 and described ground pad 3 are connected to the downside of described bolt head 11 in turn, the edge of described ground pad 3 lower surface is provided with pad angle 31, and the sharp-pointed portion 32 at described pad angle 31 is towards described threaded rod 12 lower end.
The outer surface of described connecting bolt 1, described spring shim 2 and described ground pad 3 is coated with one layer of zinc rete.
Described bolt head 11 is regular hexagon.
Described bolt head 11 upper surface is provided with criss-cross twist-on groove 111.
The work process of this example: by corresponding for the threaded rod 12 of connecting bolt 1 twist-on in the connecting hole of bus groove case; ground pad 3 is against on connecting hole; along with threaded rod 12 is screwed into gradually; the sharp-pointed portion 32 at the pad angle 31 of ground pad 3 lower surface edge punctures the coat of paint of bus groove case; sharp-pointed portion 32 card at pad angle 31 taps in the coat of paint punctured; increase the frictional force between ground pad 3 and bus groove case; play the effect of stop, realize conducting continuity protection by compressing connection bus groove case and compress fastening.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
