The utility model discloses a wiring harness grounding connection structure, which comprises body sheet metal, bolts, wire harness grounding, and nuts. The screw hole of the cap is a blind hole, the lower end of the nut is provided with a nut flange, the outer diameter of the nut flange is greater than the outer diameter of the bolt flange, and the outer diameter of the bolt flange is greater than the outer diameter of the wire harness ground connection end. Install the nut on the bolt, and the end face of the flange of the bolt will not be covered by the coating after passing through the electric pool. When assembling, unscrew the nut first, put the wiring harness on the ground, and then install the nut. The liquid will not infiltrate through the thread on the bolt into the bonding surface between the wiring harness ground and the bolt flange, which will cause the bonding surface to rust and affect the electrical conductivity. The utility model solves the problem in the prior art that the connection surface of the automobile wire harness ground and the wire harness ground are easily covered by plating and liquid easily penetrates to make the connection rust, thus affecting the electrical conductivity of the wire harness ground.
Description
Technical field
The utility model relates to a kind of syndeton, and more particularly, it relates to the wire harness bonding syndeton of using on a kind of automobile.
Background technology
All come the rat tail bonding on the now general automobile by weld bolt or nut on the vehicle body panel beating.Enter the application workshop through behind the tiselius apparatus at the vehicle body panel beating, can be covered by coating, so just make the contact resistance increase of wire harness bonding, influence electric property with the mating surface of wire harness bonding.And the screw of nut is a through hole in the present fit, so just has liquid and is seeped on the wire harness bonding by screw thread, causes wire harness bonding joint face to get rusty, and influences electric conductivity.Chinese patent notification number CN201541094U, August 4 2010 day for announcing, the name of utility model is called a kind of wire harness fixing device, this application case discloses the wire harness fixing device that uses on a kind of automobile, wire harness bonding link is provided with the bolt hole, the wire harness bonding is provided with semicircular wire harness fixed card, at bolt wire harness bonding and vehicle body panel beating are fixed together, all wire harness are fixed in the wire harness fixed card, make cabling more neat, influence electric conductivity but the joint face of this wire harness fixing device vehicle body panel beating and wire harness bonding is covered by coating easily, liquid also infiltrates link position easily and is got rusty in the junction in addition.
Summary of the invention
For solve in the automotive wire bundle bonding syndeton that joint face with the wire harness bonding is covered by coating easily and liquid easily infiltration got rusty in the junction, thereby influence the problem of the electric conductivity of wire harness bonding.The utility model provides a kind of wire harness bonding syndeton, and it can prevent in the wire harness bonding syndeton that joint face with the wire harness bonding is covered by coating and the infiltration of liquid.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of wire harness bonding syndeton, comprise the vehicle body panel beating, be welded on bolt on the vehicle body panel beating, be enclosed within wire harness bonding on the bolt, be connected the nut on the bolt, be provided with bolt flange with wire harness bonding link on the described bolt, the external diameter of bolt flange is greater than the external diameter of wire harness bonding link, the screw of described nut is a blind hole, link with the wire harness bonding on nut is provided with the nut flange, and the external diameter of nut flange is greater than the external diameter of bolt flange.After receiving stud weld on the vehicle body panel beating, load onto nut, the vehicle body panel beating is delivered to the application workshop through behind the tiselius apparatus, because the external diameter of nut flange is greater than the external diameter of bolt flange, so the bolt flange end face just can not covered by coating.During assembling, back out nut earlier, wire harness bonding on the suit, and then load onto nut.Because the screw of nut is a blind hole, and the external diameter of wire harness bonding link so liquid just can not penetrate into the binding face of wire harness bonding and bolt flange by the screw thread on the bolt, influences electric conductivity thereby binding face is got rusty less than the external diameter of bolt flange.
As preferably, the head of described nut is hemispheric, and the middle part is a hexagon, and the bottom is columniform nut flange, is provided with the changeover portion of truncated cone-shaped between middle part and bottom, and described bolt flange is cylindrical.Nut head hemisphere is difficult for hurting the people, and the middle part hexagon makes things convenient for the stressed of nut when installation and removal, and columniform flange processing is simple.
As preferably, described wire harness bonding link outward flange is provided with the projection of bending, the groove that the bolt flange end face is provided with and projection cooperates.Just had good positioning after wire harness bonding link is fixing like this, the wire harness bonding just can not rotate.
Compared with prior art, the beneficial effects of the utility model are: (1) prevents to be covered by coating between wire harness bonding link and the bolt flange binding face, thereby influences electric conductivity; (2) prevent that liquid from penetrating between wire harness bonding link and the bolt flange binding face by screw thread, gets rusty binding face, thereby influence electric conductivity.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a cutaway view of the present utility model;
Among the figure: 1, nut, 2, bolt, 3, the wire harness bonding, 4, the nut flange, 5, bolt flange.
Embodiment
Below by specific embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described specifically:
Embodiment: a kind of wire harness bonding syndeton (referring to accompanying drawing 1), comprise vehicle body panel beating, bolt 2, nut 1, wire harness bonding 3, bolt 2 projection weldings are provided with columniform bolt flange 5(referring to accompanying drawing 2 near vehicle body panel beating welding ends on the bolt 2 on the vehicle body panel beating).The screw of nut 1 is a blind hole, and head is hemispheric, and the middle part is a hexagon, and the bottom is columniform nut flange 4, is provided with the changeover portion of truncated cone-shaped between middle part and bottom.The external diameter of nut flange 4 is greater than the external diameter of bolt flange 5.The outward flange of wire harness bonding 3 links is provided with the projection of bending, and bolt flange 5 end faces are provided with the groove that cooperates with projection.Nut 1 is tightened on the bolt 2, passes through the tiselius apparatus in application workshop then, because the external diameter of nut flange 4 is greater than the external diameter of bolt flange 5, so the end face of bolt flange 5 just can not covered by coating.Behind the assembly shop, back out nut 1 earlier, wire harness bonding 3 on the suit is in the same place the projection of wire harness bonding 3 links and the groove fit on the bolt flange 5, loads onto nut 1 then and tightens.The wire harness bonding just has been connected on the bolt 2 tightly like this.The external diameter of wire harness bonding 3 links is less than the external diameter of bolt flange 5, so wire harness bonding 3 links just have been fitted in the middle of bolt flange 5 end faces.Because the screw on the nut 1 is a blind hole, thus liquid just can not penetrate on the binding face between wire harness bonding 3 links and the bolt flange 5 by screw thread, thereby the electric conductivity of wire harness bonding 3 is affected.
Above-described embodiment is a kind of preferable scheme of the present utility model, is not that the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
