Description

Technical Field

[0001] The utility model relates to a grounding wire installation structure, which belongs to the technical field of grounding wires. Background Art

[0002] Grounding wires are also called conductive jumper wires, jumper grounding wires, and conductive jumper wires. They are used in aircraft, automobiles, and other fields to conduct electricity between various components to obtain the best possible conductivity. For example, in gas-powered vehicles, grounding wires need to be installed between the gas cylinder and the frame.

[0003] The installation of the grounding wire in the prior art is relatively cumbersome. For example, when the grounding wire is connected to the gas cylinder of a gas vehicle and the frame, a screw hole for installation needs to be reserved on the frame. During the actual installation, the insulating paint at the reserved hole needs to be removed with an angle grinder, and then the terminal at one end of the grounding wire is fixed to the frame by a screw threadedly connected to the reserved hole. The above installation method has limitations. The installation screw hole needs to be reserved, resulting in a fixed installation position, poor installation flexibility, and the insulating paint needs to be removed, resulting in cumbersome on-site installation and affecting production efficiency. Utility Model Content

[0004] The utility model provides a grounding wire installation structure, the purpose of which is to overcome the above-mentioned shortcomings of the prior art and simplify the installation of the grounding wire.

[0005] The technical solution of the utility model is as follows: a grounding wire installation structure, which includes a grounding wire terminal and a grounding wire installation structure body, the grounding wire installation structure body includes a self-tapping screw, a fixing screw and a gasket, the self-tapping screw is screwed into the installation part, a screw hole is arranged at the center of the self-tapping screw head, the threaded part is sleeved with the fixing screw of the grounding wire terminal and is threadedly connected in the screw hole, the fixing screw head, the grounding wire terminal and the self-tapping screw head are pressed and connected to each other, a gasket is arranged between the bottom surface of the self-tapping screw head and the installation part, and the self-tapping screw head, the gasket and the installation part are pressed and connected to each other.

[0006] Preferably, the gasket is a polyurethane gasket, which can buffer the impact force when the self-tapping screw is in place, isolate the self-tapping screw from external corrosion factors of the mounting part, and meet the performance requirements.

[0007] The utility model has the advantages of reasonable structural design, which can effectively simplify the installation of the grounding wire and widen the installation position of the grounding wire to meet the use requirements of various working conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a structural schematic diagram of the grounding wire installation structure of the utility model.

[0009] In the figure, 1 is a grounding wire terminal, 2 is a grounding wire mounting structure body, 21 is a self-tapping screw, 22 is a screw hole, 23 is a fixing screw, 24 is a gasket, and 3 is a mounting portion. DETAILED DESCRIPTION

[0010] The present invention is further described in detail below in conjunction with embodiments and specific implementation methods.

[0011] like Figure 1 As shown, a grounding wire installation structure comprises a grounding wire terminal 1 and a grounding wire installation structure body 2, the grounding wire installation structure body 2 comprises a self-tapping screw 21, a fixing screw 23 and a gasket 24, the self-tapping screw 21 is screwed into the installation part 3, a screw hole 22 is arranged at the center of the head of the self-tapping screw 21, the fixing screw 23 with the grounding wire terminal 1 sleeved on the threaded part is threadedly connected in the screw hole 22, the head of the fixing screw 23, the grounding wire terminal 1 and the head of the self-tapping screw 21 are pressed and connected to each other, a gasket 24 is arranged between the bottom surface of the head of the self-tapping screw 21 and the installation part 3, the head of the self-tapping screw 21, the gasket 24 and the installation part 3 are pressed and connected to each other.

[0012] According to the above structure, during installation:

[0013] 1) Place the gasket 24 on the mounting portion 3 to be connected to the ground wire terminal 1 and screw in the self-tapping screw 21;

[0014] 2) Put the ground wire terminal 1 onto the threaded part of the fixing screw 23;

[0015] 3) Screw the fixing screw 23 with the terminal 11 into the screw hole 22 of the self-tapping screw 21 to complete the installation of the grounding wire.

[0016] To ensure the feasibility of installation, the hardness of the self-tapping screw 21 should be higher than the hardness of the installation part 3.

[0017] The gasket 24 can be made of polyurethane material, which can buffer the impact force when the self-tapping screw is in place, isolate the self-tapping screw and the external corrosion factors of the installation part, and meet the performance requirements. Example

[0018] The application scenario is the connection between a 1000L natural gas cylinder of a fuel truck and a vehicle frame. The natural gas cylinder is provided with a structure connected to a grounding wire terminal 1 at one end. Therefore, the mounting part 3 is the vehicle frame at this time. It is only necessary to connect the vehicle frame to the grounding wire terminal 1 at the other end through a grounding wire mounting structure body 2. The length of the self-tapping screw 21 should be less than the thickness of the vehicle frame of the mounting part 3 to meet the installation requirements. The installation position does not need to remove the insulating paint, which is convenient and quick.

[0019] All the components mentioned above are prior art, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0020] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
