As shown in fig. 1, the conventional connection device requires that the housing 7 is pre-sleeved on the wire 8, and then the wire protective sleeve 9 is formed on the wire 8 by injection molding. The part of the wire protective sleeve 9 which needs to be arranged in the shell 7 is arranged into a square-table-shaped structure. The wire 8 is pulled in the mounting direction C to mount the wire protective sheath 9 in place, thereby completing the mounting. However, when the installation space is narrow, the wire cover 9 interferes with the housing 7, and the installation is not possible. Another connecting device for connecting the wire 8 with the housing 7 by using a screw structure is not only difficult to install, but also is more easily damaged for a connecting device with a complicated working environment.

From this, the utility model provides a new connecting device.

The connecting ring 31 is partially exposed compared with the injection molding part of the wire joint 3, and the outer diameter of the connecting ring 31 is the same as the bore diameter of the wire passing hole 41. The first end of the wire joint 3 is further provided with a step structure 32, and the diameter of the step structure 32 is larger than the aperture of the mounting hole 12, so as to prevent the filler 5 from overflowing. It is to be understood that the number of the step structures 32 may be set as desired, and two step structures 32 are set in the present embodiment.

As shown in fig. 8, the first end of the wire joint 3 integrally formed with the wire 2 protrudes into the accommodating chamber 11 of the housing 1. The mounting rack 4 is arranged in the accommodating cavity 11 and is fixedly connected with the wire joint 3 and the shell 1 respectively.

Specifically, referring to fig. 3 and 4, as shown in fig. 9, the first end of the wire joint 3 and the first end of the wire 2 extend into the accommodating cavity 11 through the mounting hole 12, and the second end of the wire joint 3 and the second end of the wire 2 extend to the outside of the housing 1 through the mounting hole 12. Wherein the diameter of the contact portion of the wire joint 3 with the mounting hole 12 is equal to the diameter of the mounting hole 12 and smaller than the diameter of the stepped structure 32.

Specifically, the size of the mounting bracket 4 is smaller than that of the accommodating cavity 11, so that the mounting bracket 4 can be conveniently arranged. The connecting ring 31 passes through the wire passing hole 41 of the mounting bracket 4, and the main body 42 of the mounting bracket 4 is fixedly connected with the connecting ring 31 at the wire passing hole 41. In an alternative implementation, the diameter of the connection ring 31 is the same as the bore diameter of the wire through hole 41.

In this embodiment, the bending portion 43 of the mounting bracket 4 is connected with the upper surface of the boss 13 inside the housing 1, so as to position the mounting bracket 4, facilitate the fixing connection between the main body portion 42 and the side wall of the boss 13, and enhance the connection strength between the mounting bracket 4 and the housing 1. In the present embodiment, the main body 42 and the bent portion 43 of the mounting bracket 4 are welded to the housing 1, and the connection ring 31 is welded to the main body 42 at the wire passage hole 41.
