The terminal rotation-preventing module comprises a bolt, a terminal and a nut; the bolt comprises a head and a screw rod, and an engagement structure is arranged on a connecting surface between the head of the bolt and the terminal to limit the terminal to rotate relative to the bolt.

Description

Terminal rotation-proof module

Technical Field

The utility model relates to a module is prevented changeing by terminal belongs to car wiring harness technical field.

Background

In order to prevent the terminal from rotating in the installation process, the terminal is prevented from rotating through an additional auxiliary installation support or a vehicle body structure in the prior art, so that the manufacturing cost and the process difficulty are increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art and provides a terminal anti-rotation module which is characterized by comprising a bolt, a terminal and a nut; the bolt comprises a head and a screw rod, and an engagement structure is arranged on a connecting surface between the head of the bolt and the terminal to limit the terminal to rotate relative to the bolt.

Further, the bite structure includes: the terminal comprises a protrusion arranged on at least one surface of the terminal and a groove arranged on one surface of the bolt head close to the screw rod; the protrusions are engaged with the grooves.

Further, the protrusions and/or the grooves are uniformly arranged in the radial direction.

Further, still including resistant falling to glue, resistant falling is glued and is located on the screw rod.

Further, the bolt, the terminal and the nut are all made of metal materials.

Further, the terminal surface is plated with any one of a layer of nickel, gold, silver, zinc, and tin.

Further, the terminal includes a wire crimp part including a core wire crimp part and an insulating layer crimp part.

Compared with the prior art, the utility model discloses the beneficial effect who reaches: through the interlock structure of terminal and bolt, need not through supplementary installing support or body structure prevent changeing in the installation, can avoid the terminal to take place relative rotation in the use simultaneously to reach the mesh that reduces manufacturing cost and simplify the project organization.

Drawings

FIG. 1 is a schematic view of the exploded structure of the present invention;

fig. 2 is a schematic view of the assembly structure of the present invention.

In the figure: 1. a bolt; 2. a terminal; 3. a nut; 4. a wire crimping part; 5. a protrusion; 6. a groove; 7. glue falling resistance; 8. a bolt fixing hole; 9. a core wire crimping part; 10. and an insulating layer crimping part.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

It should be noted that, in the description of the present invention, the terms "front", "rear", "left", "right", "upper", "lower", "inner", "outer", etc. indicate the directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for convenience of description of the present invention but do not require the present invention to be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention. As used in the description of the present invention, the terms "front," "back," "left," "right," "up," "down" and "in" refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in fig. 1, it is the utility model discloses the disassembly structure sketch map, the terminal prevents changeing the module and includes: a bolt 1, a terminal 2 and a nut 3; the terminal 2 is provided with a bulge 5; the bolt 1 comprises a head and a screw, one surface of the head of the bolt 1, which is close to the screw, is provided with a groove 6, and the screw is provided with a falling-resistant glue 7; the terminal 2 is further provided with a wire crimping part 4 and a bolt fixing hole 8, and the wire crimping part 4 includes a core wire crimping part 9 and an insulating layer crimping part 10.

As shown in fig. 2, the assembly structure of the present invention is schematically illustrated, when assembling, firstly, the insulation layer is removed from one end of the wire harness and the wire crimping portion 4 of the terminal 2 is crimped, wherein the wire core is crimped onto the wire core crimping structure 9, and the insulation layer is crimped onto the insulation layer crimping portion 10, so as to ensure that the wire and the terminal 2 will not fall off when in use. Then, the terminal 2 is hung on the bolt 1, and the protrusion 5 of the terminal 2 is engaged with the groove 5 of the bolt 1. Finally, the nut 3 is assembled on the bolt 1, and the falling-resistant glue 7 is arranged on the screw rod of the bolt 1, so that the nut 3 can be prevented from being separated from the bolt 1 due to vibration when in use.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
