[0027] Referring to Figure 1 shown, the present utility model provides a technical solution: an anti - detachment joint for an automotive cable, including a plug 1, and an electric wire 2 is electrically installed on the surface of the plug 1.
[0028] The following specifically describes its overall specific settings and functions.
[0029] In this embodiment: Four storage grooves 3 are evenly formed on the side wall of the plug 1. A limit rod 10 is fixedly connected to the bottom wall of the storage groove 3. A support bar 4 is slidably connected to the side wall of the limit rod 10. The other side of the support bar 4 is fixedly connected to a connecting rod 11. The connecting rod 11 has a bent structure. An external thread 5 is formed on the side of the plug 1 close to the electric wire 2, and a screw ring 6 is threadedly connected to the surface of the external thread 5. The sliding of the support bar 4 on the surface of the limit rod 10 plays a role in restricting the moving direction of the limit rod 10. The support bar 4 will support on the inner side of the socket, thereby increasing the resistance during the process of the plug 1 being pulled out inside the socket, and improving the anti - detachment effect during the use of the plug 1. A number of protrusions 12 are fixedly connected to the side wall of the support bar 4, and the cross - section of the protrusion 12 is triangular. The protrusions 12 on the support bar 4 support on the inner side of the socket, further increasing the resistance during the process of pulling the plug 1.
[0030] An elastic rope 9 is sleeved on the outer periphery of the four support bars 4, and the elastic rope 9 has a circular ring structure. When the screw ring 6 is rotated in the reverse direction, the four support bars 4 will be simultaneously contracted into the inner side of the storage groove 3 under the elastic force of the elastic rope 9. An annular groove 8 is formed on the surface of the plug 1, and the elastic rope 9 is located inside the annular groove 8. Setting the elastic rope 9 inside the annular groove 8 can avoid the situation that the elastic rope 9 runs off during use.
[0031] Specifically, the side wall of the spiro ring 6 is provided with anti-slip patterns. The anti-slip patterns on the spiro ring 6 increase the friction between the hand and the spiro ring 6, facilitating the twisting operation of the spiro ring 6. The end side of the spiro ring 6 is rotatably connected to a rotating ring 7. The rotating ring 7 prevents the spiro ring 6 from directly squeezing the connecting rod 11, and the phenomenon of easy wear on the surface of the connecting rod 11 during the twisting process can be avoided. Four card slots 13 are formed in the side wall of the rotating ring 7, and the connecting rod 11 is located inside the card slots 13. The connecting rod 11 will be stuck inside the card slots 13, which can improve the stability of driving the connecting rod 11 during the process of twisting the spiro ring 6.
[0032] Working principle: After inserting the plug 1 into the inner side of the socket, rotate the spiro ring 6 on the surface of the external thread 5. The anti-slip patterns on the spiro ring 6 increase the friction between the hand and the spiro ring 6, facilitating the twisting operation of the spiro ring 6. At this time, the driving operation of the rotating ring 7 can be realized. The rotating ring 7 prevents the spiro ring 6 from directly squeezing the connecting rod 11, and the phenomenon of easy wear on the surface of the connecting rod 11 during the twisting process can be avoided. The connecting rod 11 will be stuck inside the card slots 13, which can improve the stability of driving the connecting rod 11 during the process of twisting the spiro ring 6. Since the spiro ring 6 will drive the relative movement between the rotating ring 7 and the connecting rod 11, the rotating ring 7 will drive the connecting rods 11 of the four bending mechanisms to expand outwards simultaneously, and further the driving operation of the support bar 4 can be realized. Among them, the sliding of the support bar 4 on the surface of the limiting rod 10 plays a role in restricting the moving direction of the limiting rod 10. The support bar 4 will support on the inner side of the socket, thereby increasing the resistance during the process of the plug 1 being pulled out inside the socket, improving the anti-detachment effect during the use of the plug 1. The convex block 12 on the support bar 4 supports on the inner side of the socket, further increasing the resistance during the process of pulling the plug 1, and further improving the stability during the use of the plug 1. Rotate the spiro ring 6 in the reverse direction, and the four support bars 4 will be simultaneously contracted into the storage groove 3 under the elastic force of the elastic rope 9, thereby facilitating the removal of the plug 1 located inside the socket. Setting the elastic rope 9 inside the annular groove 8 can avoid the situation of the elastic rope 9 running off during use. By setting the above structure, the flexible contraction of the support bar 4 on the side position of the plug 1 is facilitated. By driving the distance between the support bar 4 and the plug 1, the tightness of the plug 1 inserted into the inner side of the socket can be flexibly adjusted, avoiding the situation that the plug 1 is easily loosened or detached from the inner side of the socket under the action of external force on the wire 2, and improving the anti-detachment effect during the use of the plug 1 to a certain extent.
