Abstract
The invention relates to a bonding bolt, which comprises a head part and a screw part, wherein a concave part is formed in the middle of the screw part; and the surface shape of the concave part is a part of a cylindrical surface and is provided with a thread with the same turning direction as that of a thread of a main body of the screw part. By the bonding bolt, the shortcomings in the prior art are overcome; the thread of the screw part is a non-standard thread, so painting layers on a metal plate and a frame can be damaged effectively; and undesirable bonding can be avoided.
Description
Technical field
The present invention relates to a kind of bonding bolt.
Background technique
At present automotive electronics is used more and more widely, during the automobile bad earth, problem such as can occur having started not, instrument does not show, car light does not work.Mostly the bonding position is to connect with the common standard bolt now; One end of wire harness bonding terminal is a ring structure; The ring structure that screws in the bonding terminal through standard bolt is connected the bonding terminal with vehicle body panel beating or vehicle frame, the tail end of bonding bolt is fixed the bonding terminal through nut.In assembly process, normally connect with standard bolt, often can not well destroy the skin of paint on panel beating, the vehicle frame; Skin of paint is as isolation layer; Just cut off being connected of bonding terminal and panel beating, vehicle frame, bad earth phenomenon that Here it is can cause circuit loop to disconnect.
Therefore,, adapt to the needs of reality, be necessary to design a kind of bonding bolt, can effectively cause good destruction, avoid the generation of bad earth phenomenon the skin of paint on panel beating, the vehicle frame in order to overcome the deficiency of existing technology.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing technology, adapt to the needs of reality, a kind of bonding bolt is provided.
In order to realize the object of the invention, the technological scheme that the present invention adopts is:
A kind of bonding bolt comprises head and screw part, and the middle part of said screw part is provided with depressed part, and the surface configuration of said depressed part is the part of cylndrical surface and is provided with the screw thread consistent with the thread rotary orientation of screw part main body.
The free end of said screw part is round table-like contraction and is provided with dregs guiding groove, and said dregs guiding groove is connected with the depressed part at said screw part middle part.
For being used for the contraction neck of suit bonding terminal, said contraction neck outside is set with spring washer and plain washer successively between the screw thread starting point of said head and screw part.
Beneficial effect of the present invention is:
1. overcome the defective of existing technology, the screw thread of screw part is an odd-pitch screw, can more effectively destroy the skin of paint on panel beating, the vehicle frame, has prevented the generation of bad earth phenomenon;
2. the screw part free end is provided with dregs guiding groove, helps in the process that screw rod screws in, and the discharge of paint chip makes bonding bolt more firm with being connected of panel beating, vehicle frame;
3. simple in structure, cheap, realize easily.
Description of drawings
Fig. 1 is one of structural representation of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the right elevation of screw part among Fig. 1;
Fig. 4 is two of a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Embodiment one: referring to Fig. 1, and Fig. 2, Fig. 3.
A kind of bonding bolt comprises head 1 and screw part 2, and the middle part of said screw part 2 is provided with depressed part 3, and the surface configuration of said depressed part 3 is the part of cylndrical surface and is provided with the consistent screw thread of thread rotary orientation with screw part 2 main bodys.In the present embodiment, said bonding bolt is a hexagon head bolt.The screw thread of screw part is an odd-pitch screw, has overcome the defective of existing technology, can more effectively destroy the skin of paint on panel beating, the vehicle frame, has prevented the generation of bad earth phenomenon.
The free end of said screw part 2 is round table-like contraction and is provided with dregs guiding groove 4, and said dregs guiding groove 4 is connected with the depressed part 3 at said screw part 2 middle parts.Screw part 2 free ends are provided with dregs guiding groove 4, help in the process that screw rod screws in, and the discharge of paint chip makes bonding bolt more firm with being connected of panel beating, vehicle frame.
For being used for the contraction neck 5 of suit bonding terminal, said contraction neck 5 outsides are set with spring washer 6 and plain washer 7 successively between the screw thread starting point of said head 1 and screw part 2.
Use principle is following:
The bonding terminal is inserted in shrinks neck 5, be inserted in spring washer 6 and plain washer 7 then in order, again the free end of the screw part 2 of bonding bolt is screwed in the predeterminated position that panel beating, vehicle frame etc. locate and get final product.
Embodiment two: referring to Fig. 4.
Present embodiment and embodiment one are basic identical, and its something in common is not given unnecessary details, and difference only is that in the present embodiment, said bonding bolt is a phillips head bolts.
What embodiments of the invention were announced is preferred embodiment, but is not limited thereto those of ordinary skill in the art; Very easily, understand spirit of the present invention, and make different amplifications and variation according to the foregoing description; But only otherwise break away from spirit of the present invention, all in protection scope of the present invention.
Claims (3)
1. a bonding bolt comprises head and screw part, it is characterized in that: the middle part of said screw part is provided with depressed part, and the surface configuration of said depressed part is the part of cylndrical surface and is provided with the screw thread consistent with the thread rotary orientation of screw part main body.
2. bonding bolt according to claim 1 is characterized in that: the free end of said screw part is round table-like contraction and is provided with dregs guiding groove, and said dregs guiding groove is connected with the depressed part at said screw part middle part.
