Embodiment Construction

[0014] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0015] see figure 1 , the grounding bolt mechanism used for fixing the grounding terminal of the automobile wiring harness includes a grounding bolt, the upper part of the grounding bolt is a nut 2, the middle part is a shaft, and the lower part is a stud 1, and the middle shaft is covered with a spring washer 3 Peace washers4. The axially symmetrical sides of the stud 1 are flattened planes 1.1, see figure 2 , the diameter of the stud 1 is 12mm, and the width between the flattened planes on both sides of the stud is 10mm; the lower end of the stud is an inverted cone, and three oblique The mouth groove 1.2 and the oblique groove 1.2 are axial grooves, and are trumpet-shaped grooves with a small upper part and a larger lower part, see image 3 , three oblique slots 1.2 form a reamer shape.

[0016] see Figure 4 , when assembling, first se...

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 [0001] The invention belongs to the technical field of automobile electrical technology, and in particular relates to a grounding bolt used for fixing a grounding terminal of an automobile wiring harness. Background technique [0002] The power supply of automobile electrical is divided into positive pole and negative pole. The negative pole of the automobile wiring harness is a hole terminal. The hole terminal is connected with the car body sheet metal (frame) with bolts and nuts, referred to as the ground terminal, and the negative pole of the battery is also used in this way. Received on the sheet metal (frame), so that the sheet metal (frame) of the car body becomes the public negative pole. In order to ensure the reliability of grounding during the assembly of the current grounding terminal, the paint on the contact sheet metal (frame) of the grounding terminal is manually scraped off before assembly, and then the grounding terminal is assembled. Apply ...
