Abstract
The utility model relates to a bonding bolt, including the bolt body, one end at the bolt body is provided with the external screw thread, be provided with four group's indentations on the external screw thread, be first group indentation, second group indentation, third group indentation and fourth group indentation respectively, first group indentation, second group indentation, third group indentation and fourth group indentation all are located the same thread of external screw thread. The design to indentation on the external screw thread is passed through in this application, and it is great to have solved automobile bonding bolt contact resistance, and the unstable problem of wire performance for the bonding bolt contact resistance greatly reduced of FT screw, has ensured the stability of electric property.
Description
Technical field
This utility model belongs to technical field of fastening, particularly relates to a kind of bonding bolt connecting for same vehicle body.
Background technology
The electrical system overwhelming majority on automobile adopts one wire system, using wire by the negative pole of accumulator or electric component with
The metal part of vehicle body connects, and this root wire is commonly referred to ground strap, and metal terminal (bonding terminal) one end of ground strap is ring
Shape structure, screws in the circulus of bonding terminal by the metal portion of bonding terminal 02 and vehicle body sheet metal 01 or vehicle frame by bolt
Divide and connect, bonding terminal is fixed by nut by the tail end of bolt, this position is referred to as bonding dots (Fig. 1), the fixing spiral shell of bonding dots
Bolt is bonding bolt 03.
The quality of bonding dotted state is the key of electrical apparatus for vehicle use work quality, because electrical appliance transmits electricity by bonding dots
Stream, if bonding dots loose contact, can lead to electrical appliance cisco unity malfunction, and such as electromotor cannot start, lamp does not work, water temperature
Exception is too high, engine speed is unstable, accumulator cannot charge normal, and therefore, the importance of bonding dots is self-evident, with
When, the size of bonding dots resistance is to weigh the key index of bonding dots performance, and bonding bolt decides the steady of bonding dots resistance
Qualitative, because bonding bolt not only fixes bonding terminal on vehicle body, participate in transmission electric current, therefore, bonding bolt one simultaneously again
Denier loosens or loose contact, will affect the function of electrical appliance.
The thread 04 of the bonding bolt 03 of prior art is ft thread, as shown in Fig. 2 its ft thread is manual impression, only
There is the impression of two groups of symmetrically structures.There is leakage pressure risk and less efficient, relatively costly, image full inspection machine simultaneously in manual impression
None- identified, especially impression size scattered error are big, and homogeneity of product is poor, and fraction defective is higher, in assembling process, easily occurs leading
Electrical property is bad.
Utility model content
The purpose of this utility model is to provide a kind of bonding bolt, larger to solve automobile bond threaded bolt contacts resistance, leads
The problem of line unstable properties.
This utility model is achieved through the following technical solutions:
A kind of bonding bolt, including bolt body；One end of described bolt body is provided with external screw thread；
Four groups of impressions are provided with described external screw thread, respectively first group impression, second group of impression, the 3rd group of impression and
4th group of impression；
Described first group of impression, described second group of impression, described 3rd group of impression and described 4th group of impression are respectively positioned on institute
State on externally threaded identical thread.
Described first group of impression and described 3rd group of impression are with the centrage of described bolt body for axis of symmetry centrosymmetry；
Described second group of impression and described 4th group of impression are with the centrage of described bolt body for axis of symmetry centrosymmetry.
Described first group of impression, the shape of described second group of impression, described 3rd group of impression and described 4th group of impression and
Structure all same.
The width of the impression plane being located on each thread in described first group of impression is all higher than and described first group of impression
The axial width of junction thread.
The beneficial effects of the utility model are:
, by the design to impression on external screw thread, it is larger to solve automobile bond threaded bolt contacts resistance, wire-conducting performance for the application
The unstable problem of energy, by real vehicle batch testing, enging cabin bonding dots contact resistance is stablized in below 0.4m ω, and interior is taken
Iron spot contact resistance is stablized in below 0.8m ω, substantially reduces with respect to the bonding bolt contact resistance of ft screw thread, has ensured electricity
The stablizing of gas performance.

Description of reference numerals
01 vehicle body sheet metal, 02 bonding terminal, 03 bonding bolt, 04 thread, 1 bolt body, 2 external screw threads, 3 first groups of pressures
Trace, 4 two groups of impressions, 5 the 4th groups of impressions.
Specific embodiment
To describe the technical solution of the utility model by the following examples in detail, below example is only exemplary
, it is only capable of for explaining and the technical solution of the utility model being described, and be not to be construed as to technical solutions of the utility model
Restriction.
The application provides a kind of bonding bolt, as shown in Figure 3 and Figure 4, including bolt body 1；In described bolt body 1
One end is provided with external screw thread 2；In this application, bolt body is same as the prior art, and its external screw thread is also prior art.Bonding
After bolt passes through the binding post of wire, it is tightened on vehicle body, realize electrically connecting with vehicle body using bonding bolt.
Four groups of impressions, 3, second group of impression 4 of respectively first group impression, the 3rd group of pressure are provided with described external screw thread 2
Trace (not shown) and the 4th group of impression 5；Described first group of impression, described second group of impression, described 3rd group of impression and institute
State the 4th group of impression to be respectively positioned on described externally threaded identical thread.
Described first group of impression and described 3rd group of impression are with the centrage of described bolt body for axis of symmetry centrosymmetry；
Described second group of impression and described 4th group of impression are with the centrage of described bolt body for axis of symmetry centrosymmetry.
Described first group of impression, the shape of described second group of impression, described 3rd group of impression and described 4th group of impression and
Structure all same.
The width of the impression plane being located on each thread in described first group of impression is all higher than and described first group of impression
The axial width of junction thread.
The impression of the bonding bolt of the application passes through dental lamina extrusion molding during thread rolling, and complete by image
Inspection machine is capable of identify that whether screw thread leaks impression, can effectively anti-leak-stopping pressure, impression dimensional tolerance is little simultaneously, and homogeneity of product is relatively
High.
The application passes through four groups of impressions, and in assembling process, bonding bolt is abundant with the metal part of vehicle body or vehicle frame
Contact, reduces contact resistance, electric conductivity is excellent, thus improve the reliability of car load.
The above is only the description of the preferred implementation of utility model it is noted that limited due to literal expression
Property, and objectively there is unlimited concrete structure, for those skilled in the art, without departing from this reality
On the premise of new principle, some improvements and modifications can also be made, these improvements and modifications also should be regarded as this utility model
Protection domain.
