Description
Technical field
The utility model relates to the technical field of electric appliances of heavy vehicle and engineering machinery, especially a kind of special wire harness bonding bolt.
Background technique
Automobile is the traffic tool of motion, does not resemble ordinary appliances transfixion, thus, usually easily occurs ground strap bad connection or ground strap open circuit, gently then affect the function of automobile aspect, heavy then make automobile in paralyzed state.Current, conventional automobile bond needs first to be removed by the enamelled coating on bonding dots surface, then receives on bonding dots by bolt by bonding terminal, and in installation process, paint removal operation comparatively trouble, length consuming time, weak effect, easily comes in contact bad phenomenon.
In order to simplify bonding process, promote paint removal efficiency, developing special wire harness bonding bolt becomes the technical task with numerous benefit.
Model utility content
In view of the deficiencies in the prior art, the purpose of this utility model is a kind of special wire harness bonding bolt of design, and in bolt installation process, complete paint removal operation, paint removal is simple, quick and reliable for effect simultaneously.
To achieve these goals, the utility model provides a kind of special wire harness bonding bolt, its two ends are respectively equipped with screw thread, middle part was provided with aperture apparatus, wherein, via hole apparatus surface is provided with tooth, during installation, first special wire harness bonding bolt is fixed on bonding body, tenminal block is placed on special wire harness bonding bolt again, then fastening nut, now, the tooth of via hole apparatus surface scrapes the enamelled coating of the mounting hole of bonding body off, achieves the excellent electric contact of tenminal block and special wire harness bonding bolt and bonding body.
Preferably, in the middle part of special wire harness bonding bolt, being also provided with nut, for when attaching it on bonding body and when installing tenminal block, being convenient to fixing special wire harness bonding bolt.
Preferably, the tooth of described via hole apparatus surface is spline or annular knurl, and during installation, the enamelled coating in the hole of bonding body extrudes by spline or annular knurl, is easy to damaged, can realizes excellent electric contact.
Preferably, described aperture apparatus is excessively taper, and the hole of bottom and bonding body is over-surplus fit structure, and during installation, the enamelled coating in the hole of bonding body was extruded by aperture apparatus, is easy to damaged, can realizes good point cantact.
Adopt the special wire harness bonding bolt of technique scheme, decrease process steps such as scraping paint or pre-embedded bolt in bonding process, enhance productivity, can excellent electric contact be realized simultaneously.

Embodiment
Understand for the ease of persons skilled in the art and realize the utility model, now further describing special wire harness bonding bolt described in the utility model in conjunction with the drawings and the specific embodiments.
A special wire harness bonding bolt as shown in Figure 2, its two ends are respectively equipped with screw thread 31, and middle part is provided with nut 32 and crosses aperture apparatus 33, and wherein, crossing aperture apparatus 33 surface has tooth 34.
As shown in Figure 4, cross aperture apparatus 33 surface and be provided with tooth 34, during installation, the mounting hole of aperture apparatus 33 through bonding body 1 will be crossed, fastening nut 5 and nut 32, the enamelled coating of the mounting hole of bonding body 1 is subject to nut 5 and crosses aperture apparatus 33 extruding, and tooth 34 scrapes the enamelled coating in the hole of bonding body 1 off, achieve bonding body 1 and the excellent electric contact of special wire harness bonding bolt 3, ensure that other is by the excellent electric contact of special wire harness bonding bolt 3 with bonding body 1.
Tooth 34 can also be spline or annular knurl, and during installation, the enamelled coating in the hole of bonding body 1 extrudes by spline or annular knurl, is easy to damaged, can realizes better electrical contact.
As shown in Figure 3 in embodiment, cross aperture apparatus 33 for taper, the width H of bottom 36 is greater than the width h of its outer end 35, further, the bottom 36 crossing aperture apparatus 33 is over-surplus fit structure with the hole of bonding body 1, during installation, tighten the nut 5 of hexagonal, the enamelled coating of the mounting hole of bonding body 1 is subject to nut 5 and crosses aperture apparatus 33 extruding, and is easy to damaged, can realizes good point cantact.
Adopt the special wire harness bonding bolt of technique scheme, decrease process steps such as scraping paint or pre-embedded bolt in bonding process, enhance productivity, can excellent electric contact be realized simultaneously.
As shown in Figure 1, be the scheme of installation of special wire harness bonding bolt described in the utility model.Special wire harness bonding bolt 3, by plain washer 2 and nut 5, is fixedly installed in bonding body 1.The two ends of special wire harness bonding bolt 3 have fixedly mounted 2 tenminal blocks 4 by nut 5, save space, reduce accessory cost.Special wire harness bonding bolt described in the utility model is applicable to the installation compared with the thick bonding dots of slab.Paint is scraped voluntarily in installation process, decrease or the process step such as pre-embedded bolt (prevent paint), improve manufacturing efficiency, bonding is respond well, the hole of tenminal block 4 is mated with the screw thread 31 of special wire harness bonding bolt, need not be consistent with the hole of bonding body 1 (that is: mounting hole), decrease accessory kind, reduce cost.Adopt special wire harness bonding bolt described in the utility model, electrical function ground connection needs can be met, also can meet the needs of electric equipment protective grounding.
Although depict the utility model by embodiment, but those of ordinary skill in the art know, when not departing from spirit of the present utility model and essence, the utility model just can be made to have many changes and distortion, and scope of the present utility model is limited to the appended claims.
