The sealing block 12 is provided with a through hole 14 for the wiring harness to pass through, and the terminal body 1 is detachably connected to a cover plate 2 for limiting the sealing block 12.

[0031] Reference Figure 1 One end of the cover plate 2 is hinged to the terminal body 1, and protrusions 21 are protruding from both sides of the cover plate 2. A clamping groove 13 for the protrusion 21 to be clamped is provided on the side of the installation cavity 11. After the sealing block 12 is installed in the installation cavity 11, the cover plate 2 is rotated so that the protrusion 21 on the cover plate 2 is clamped in the clamping groove 13, and then the cover plate 2 is limited, and the sealing block 12 is limited by the cover plate 2.

[0032] Reference Figure 1 The cross section of the protrusion 21 is semicircular, and the cross section of the protrusion 21 is semicircular, which makes it easy for the protrusion 21 to be clamped in the clamping groove 13.

[0033] The implementation principle of Example 1 of the present application is as follows: an installation cavity 11 is opened on the terminal body 1, and then a sealing block 12 is installed in the installation cavity 11. The wiring harness can be passed through the through hole 14 on the sealing block 12, and then the sealing block 12 is fixed by the cover plate 2, thereby improving the sealing performance between the wiring harness and the terminal body 1, thereby reducing installation risks.

[0034] Embodiment 2:

[0035] The difference between Example 2 and Example 1 is that, referring to Figure 2 and Figure 3The sealing block 12 is elastically arranged, and a deformation groove 15 corresponding to the penetration hole 14 is arranged on the side of the sealing block 12 close to the cover plate 2. The deformation groove 15 is arranged in an annular shape, and the deformation groove 15 is arranged coaxially with the penetration hole 14. The cover plate 2 is fixedly connected with an insertion block 22 for clamping in the deformation groove 15 to force the sealing block 12 to deform. The insertion block 22 is arranged in an annular shape and corresponds to the deformation groove 15. The sealing block 12 is an elastic block, and the sealing block 12 is provided with a deformation groove 15, and the cover plate 2 is provided with an insertion block 22 corresponding to the deformation groove 15. When the cover plate 2 is covered on the terminal body 1, the insertion block 22 is inserted in the deformation groove 15, thereby causing the sealing block 12 to deform, so that the hole wall of the penetration hole 14 squeezes the wiring harness, thereby improving the sealing performance.
