Abstract
The invention relates to a bonding bolt mechanism for fixing an automotive wiring harness bonding terminal. The upper part of a bonding bolt is a screw cap, the middle part of the bonding bolt is a rod shank, and the lower part of the bonding bolt is a stud, wherein the rod shank at the middle part is sleeved with a spring washer and a flat washer; and two axially-symmetrical side faces of the stud are flat planes, and the lower end part of the stud is a reverse cone frustum of which a reverse circular conical surface is evenly provided with three oblique grooves and the three oblique grooves are axial grooves. In the bonding bolt mechanism, the oblique grooves at the lower end of the stud of the bonding bolt and a stud structure are utilized to extrude and cut paints on threads in projection welding nuts without manually scraping the paints and coating vaseline, thus not only ensuring the working reliability of the bonding, but also greatly simplifying the assembly technology, and preferably solving the defect of time and labor waste in the existing bonding technology.
Description
Technical field
The invention belongs to the auto electric technical field, be specifically related to be used for the fixing bonding bolt of automotive wire bundle bonding terminal.
Background technology
The power supply of auto electric divides positive pole and negative pole; The negative pole of automotive wire bundle is the cellular type terminal; With bolt and nut this cellular type terminal and car body panel beating (vehicle frame) are joined together; Be called for short the bonding terminal, battery terminal negative is also received on the panel beating (vehicle frame) with this mode, and car body panel beating (vehicle frame) has just become public negative pole like this.It is reliable when existing bonding terminal assembles in order to ensure bonding; Before assembling, wipe off with the artificial paint of earlier bonding termination contact panel beating (vehicle frame) being located; Assemble the bonding terminal then, install and also will smear the vaseline protection behind the bonding terminal, prevent to get rusty; This technology wastes time and energy, and quality can't guarantee to influence simultaneously production efficiency.
Summary of the invention
For the problem of wasting time and energy of solving that existing automotive wire bundle bonding terminal assembly technology exists, poor reliability, the present invention provide a kind of improve structure be used for the fixing bonding bolt mechanism of automotive wire bundle bonding terminal.
Concrete technical solution is following:
Be used for the fixing bonding bolt mechanism of automotive wire bundle bonding terminal and comprise bonding bolt, the top of bonding bolt is nut, and the middle part is a shaft, and the bottom is a double-screw bolt, and suit spring washer and plain washer on the shaft of center.Said stud shaft is to cut flat plane to the two sides of symmetry, and the bottom of double-screw bolt is the rounding frustum, is laid with three angle grooves on the rounding conical surface of said rounding frustum, and said angle groove is an axial groove.
Said double-screw bolt diameter is 12 ㎜, and the width that cut between the flat plane double-screw bolt both sides is 8-10 ㎜.
Angle groove on the said rounding conical surface is up-small and down-big horn-like groove.
The angle groove of bonding bolt of the present invention mechanism utilization itself and bolt structure squeeze the paint of project-welding nut internal thread and slice off; Need not to scrape lacquer separately and be coated with vaseline with manual work; Promptly ensured the functional reliability of bonding; Simplify assembly technology again greatly, well solved the drawback that existing bonding technology wastes time and energy.

Double-screw bolt 1, cut flat plane 1.1, angle groove 1.2, nut 2, spring washer 3, plain washer 4, vehicle frame 5, project-welding nut 6, bonding terminal 7, automotive wire bundle 8.
Embodiment
Below in conjunction with accompanying drawing, the present invention is done explanation further through embodiment.
Referring to Fig. 1, be used for the fixing bonding bolt mechanism of automotive wire bundle bonding terminal and comprise bonding bolt, the top of bonding bolt is nut 2, and the middle part is a shaft, and the bottom is a double-screw bolt 1, and suit spring washer 3 and plain washer 4 on the shaft of center.The double-screw bolt 1 axially two sides of symmetry is to cut flat plane 1.1, sees Fig. 2, and the diameter of double-screw bolt 1 is 12 ㎜, and the width that cut between the flat plane double-screw bolt both sides is 10 ㎜; The bottom of double-screw bolt is the rounding frustum, is uniformly distributed with on the rounding conical surface of rounding frustum to offer three angle grooves 1.2, and angle groove 1.2 is an axial groove, and is up-small and down-big horn-like groove, sees Fig. 3, and three angle grooves 1.2 form the reamer shape.
Referring to Fig. 4; During assembling, earlier the bonding terminal 7 with automotive wire bundle 8 is sleeved on the bonding bolt, with air gun (or electric rifle) bonding bolt is put directly then that the bonding terminal 7 of automotive wire bundle 8 is urgent to get final product on vehicle frame 5; Three of the double-screw bolt lower end angle groove 1.2 performance reamer effects when urgent; Major part in project-welding nut on the vehicle frame 6 holes paint is wiped off, and double-screw bolt 1 can squeeze the paint of the residue in project-welding nut 6 holes and slice off, and ensures that double-screw bolt 1 and project-welding nut 6 electrically contact well, reliably.Spring washer 3 and bonding terminal 7 lockings of plain washer 4 with automotive wire bundle 8.Like this automotive wire bundle negative pole just with public negative pole vehicle frame 5 good linking together.Need not again the paint at bonding termination contact vehicle frame 5 places be wiped off, also need not smear vaseline protection, solve the problem of the loaded down with trivial details and bad earth of existing bonding assembly technology.
