DETAILED DESCRIPTION

[0018] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model will be described in detail below with reference to the drawings.

[0019] As Figure 1 , Figure 2As shown in the figure, the charging gun with the clamp provided by the embodiment of the application comprises a wire harness 1, a shell 2, a control module arranged in the shell 2 and electrically connected with the wire harness 1, a plug 3 arranged at one end of the shell 2, an end cover 4 connected with the other end of the shell 2, a connecting piece connecting the end cover 4 and the shell 2, and a clamp 5. The clamp 5 comprises a first plate 51 provided with a first hole, a protrusion 52 arranged on the first plate 51, a gasket 53, and a first bolt. One side of the protrusion 52 is provided with a first arc surface for abutting against the outer periphery of the wire harness 1. The gasket 53 is provided with a second arc surface for abutting against the outer periphery of the wire harness 1. The gasket 53 is provided with mounting holes 530 at both ends. The protrusion 52 is provided with first bolt holes 520 corresponding to the mounting holes 530. The first bolt is threadedly connected through the mounting holes 530 and the first bolt holes 520. The first plate 51 is respectively abutted against the end cover 4 and the shell 2 at both ends.

[0020] In actual assembly, after the wire harness 1 passes through the end cover 4, the wire harness 1 is connected with the control module through the first hole of the first plate 51, so that the protrusion 52 is located on one side of the wire harness 1. Then the gasket 53 is placed on the other side of the wire harness 1, and the first bolt is threadedly connected through the mounting holes 530 and the first bolt holes 520, so as to realize the assembly of the clamp 5 and the assembly of the clamp 5 on the wire harness 1, and to ensure that the clamp 5 cannot move axially along the wire harness 1. Then the end cover 4 and the shell 2, and the shell 2 and the plug 3 are assembled, so that the first plate 51 of the clamp 5 is respectively abutted against the end cover 4 and the shell 2 at both ends, and the clamp 5 cannot shake between the end cover 4 and the shell 2. In use, the wire harness 1 is pulled, and since the clamp 5 is fixed by the end cover 4 and the shell 2, and the clamp 5 is fixed with the wire harness 1, the control module connected with the wire harness 1 will not be pulled, and the wire harness 1 and the control module will not be loose or even fall off.

[0021] In the above design, the falling off of the wire harness 1 and the control module in the shell 2 caused by the pulling of the wire harness 1 during the taking and placing of the charging gun can be avoided, and the service life of the charging gun is improved.

[0022] Specifically, as shown in the figure, the gasket 53 comprises an arc-shaped piece 531 and straight pieces 532 symmetrically arranged at both ends of the arc-shaped piece 531. The first bolt holes 520 are arranged on the straight pieces 532, and the second arc surface is arranged on the arc-shaped piece 531. The second arc surface is further provided with a boss 533. Figure 4

[0023] In actual assembly, when the gasket 53 and the protrusion 52 are locked, the boss 533 will extrude the wire harness 1 to the side of the center of the wire harness 1, so as to increase the friction force between the outer wall of the wire harness 1 and the second arc surface.

[0024] In the above design, the structure of the gasket 53 can enhance the friction force between the gasket 53 and the wire harness 1, and improve the stability between the clamp 5 and the wire harness 1. ​

[0025] Specifically, as shown in Figure 5 The shell 2 includes a shell body 21 and a plurality of support ribs 22 arranged on the inner wall of the shell body 21, and the first plate 51 is in contact with the support ribs 22 away from the end cover 4. The shell body 21 is provided with a second threaded hole 200, and the end cover 4 is provided with a countersunk hole 400. The connecting piece is a second bolt.

[0026] In the above design, the support rib 22 contacts one end of the first plate 51 to quickly fix the clamp 5. The second bolt is screwed through the countersunk hole 400 and the second threaded hole 200 to fix the end cover 4 and the shell 2.

[0027] Specifically, as shown in Figure 3 The plug 3 is provided with an annular groove on the outer periphery, and the annular groove is provided with a sealing ring 6, and the sealing ring 6 is in contact with the inner wall of the shell 2.

[0028] In the above design, the sealing ring 6 fills the gap between the shell 2 and the plug 3, improving the airtightness and waterproofness of the charging gun.

[0029] Specifically, the gasket 53 is a metal gasket 53, and the protrusion 52 is a resin protrusion 52.

[0030] In the above design, the metal gasket 53 has good strength and plasticity, which can avoid fatigue failure during clamping the wire harness 1 with the clamp 5. The resin protrusion 52 has good strength and light weight, which can reduce the weight of the charging gun.

[0031] It should be understood that the above description is only a specific embodiment of the present application and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
