The outer side wall of the insulating sleeve 2 is provided with a first bump 22 along the axial direction, and the side wall of the pin housing 1 is provided with a first groove 12 along the axial direction for the first bump 22 to be inserted.
The one-way retainer ring 3 is coaxially sleeved in the first annular groove 21 on the insulating sleeve 2, the first groove 12 on the pin shell 1 is aligned with the first bump 22 on the insulating sleeve 2, and the first bump 22 axially moves in the first groove 12, so that the pin shell 1 and the insulating sleeve 2 do not rotate relatively. When one end face of the pin housing 1 abuts against the first inclined face 32 of the one-way collar 3, the one-way collar 3 can contract radially due to the notch 31 formed on the one-way collar 3. The first bump 22 continues to move axially in the first groove 12 until the outer side wall of the one-way collar 3 is clamped in the second annular groove 11, the one-way collar 3 expands radially, so that the one-way collar 3 is firmly clamped on the inner side wall of the pin housing 1 and the outer side wall of the insulating sleeve 2 at the same time, and the one-way collar 3 can limit the axial relative movement between the pin housing 1 and the insulating sleeve 2.
The inner periphery of the pin housing 1 for abutting one end of the first inclined surface 32 is provided with a second inclined surface 13. Therefore, when the pin housing 1 abuts against the first inclined surface 32 of the one-way retainer ring 3, the one-way retainer ring 3 is more easily contracted along the radial direction, so that the pin housing 1 is conveniently coaxially sleeved on the insulating sleeve 2 clamped with the one-way retainer ring 3.
Referring to fig. 2, the plug further comprises a first sleeve 5 and a second sleeve 6, one end of the first sleeve 5 is coaxially inserted into one plug 4, the second sleeve 6 is coaxially screwed on the outer side wall of the plug 4, a first boss 41 is coaxially arranged on the inner side wall of the plug 4, and the first boss 41 abuts against the pin housing 1.
The first sleeve 5, the second sleeve 6, the first boss 41 and the plug 4 are matched and assembled for use, the relative axial movement of the pin shell 1 and the plug 4 is limited jointly, the pin shell 1 is abutted against the plug 4, the pin shell 1 is firmly fixed in the plug 4, and the first sleeve 5, the second sleeve 6 and the plug 4 are connected so as to be convenient to assemble and disassemble.
Referring to fig. 3, the plug further comprises a waterproof housing 7, the waterproof housing comprises a first waterproof housing 71 and a second waterproof housing 72, the inner side wall of the second waterproof housing 72 is connected to the outer side wall of the plug 4 in a clamping manner, and the inner side wall of the first waterproof housing 71 is connected to the outer side wall of the second waterproof housing 72 in a clamping manner. The assembly between the watertight housing 7 and the plug 4 is thus simpler.
the outer side wall of one end of the plug 4 close to the second sleeve 6 is provided with a second lug 42, and the outer side wall of one end of the plug 4 far away from the second sleeve 6 is provided with a third lug 43. A second groove 711 for abutting against the second bump 42 is arranged on the side wall of one end of the first waterproof casing 71 close to the second sleeve 6, and a third groove 721 for abutting against the third bump 43 is arranged on the side wall of one end of the second waterproof casing 72 far away from the second sleeve 6.
The second projection 42 is provided to restrict the axial movement and the relative rotation between the first waterproof case 71 and the plug 4, and the third projection 43 is provided to restrict the axial movement and the relative rotation between the second waterproof case 72 and the plug 4. The second projection 42 and the third projection 43 together limit the axial movement and the relative rotation between the waterproof housing 7 and the plug 4, so that the connection between the inner side wall of the waterproof housing 7 and the outer side wall of the plug 4 is firmer and tighter.
The side of the second waterproof case 72 is provided with a strip slit 722 in the axial direction. When the second waterproof case 72 is assembled with the first waterproof case 71 and the plug 4, since the second waterproof case 72 is provided with the elongated slit 722, the diameter of the second waterproof case 72 can be increased or decreased in the assembling process, so that the second waterproof case 72 is conveniently and coaxially sleeved on the outer side wall of the plug 4, and the second waterproof case 72 is also conveniently and coaxially sleeved on the inner side wall of the first waterproof case 71.
