[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] The utility model provides Figures 1 to 8 A cable end auxiliary connector is shown, comprising:

[0029] Two insulating protective sleeves 1, with a connecting terminal 2 provided between the two insulating protective sleeves 1, a fixing ring 3 fixed to the outer end of the middle portion of the connecting terminal 2, the fixing ring 3 having a T-shaped cross-section, and sealing gaskets 4 fixed to the inner ends of both sides of the fixing ring 3. One end of the two insulating protective sleeves 1 extends to the inner ends of both sides of the fixing ring 3 and contacts the sealing gasket 4, and the cross-section of the sealing gasket 4 is an inverted L-shaped;

[0030] The rotating connecting ring 5 is provided at the outer end of the fixed ring 3, and an annular groove 12 is provided in the middle of the outer end of the fixed ring 3. An annular slider 13 is provided inside the annular groove 12. The outer end of the annular slider 13 is fixedly connected to the inner end of the rotating connecting ring 5. The cross-sections of the annular groove 12 and the annular slider 13 are both T-shaped. The outer end of the rotating connecting ring 5 is integrally connected with a plurality of anti-slip strips 14. Four limiting plates 6 are provided on the top and bottom of both sides of the outer end of the rotating connecting ring 5. The outer side of the limiting plate 6 is an arc surface. The top and bottom of one end of the two insulating protective sleeves 1 are provided with limiting grooves 7. One end of the positioning plate 6 extends into the interior of the limiting groove 7, and a connecting plate 8 is fixed between the other ends of the two limiting plates 6. The two connecting plates 8 are respectively arranged at the top and bottom of the rotating connecting ring 5. A reset spring 9 is fixed between the inner side of the connecting plate 8 and the outer end of the rotating connecting ring 5. Four limiting bolts 10 are provided at both ends of the rotating connecting ring 5, and a limiting hole 11 is opened on the limiting plate 6. One end of the four limiting bolts 10 passes through the two ends of the rotating connecting ring 5 and extends to the four limiting holes 11 on the four limiting plates 6 respectively. The limiting bolts 10 are threadedly connected to the rotating connecting ring 5.

[0031] 3, and then the ends of the two cables are passed through the two insulating protective sleeves 1 and connected to the two ends of the connecting terminals 2 respectively. Then, the two insulating protective sleeves 1 are inserted into the inner ends of the fixing rings 3 on both sides so that the ends of the insulating protective sleeves 1 are in close contact with the sealing gaskets 4. When the insulating protective sleeves 1 enter the inner ends of the fixing rings 3 on both sides, they will first contact the arc surface of the end of the limit plate 6. The insulating protective sleeves 1 will squeeze the arc surface, and the limit plate 6 will move outward under the action of the squeezing force. When the insulating protective sleeves 1 are connected, rotate the connecting ring 5 and the annular slider 13. Rotating the connecting ring 5 drives the limit plate 6 to rotate. When one end of the limiting plate 6 moves to the outside of the limiting groove 7 on the insulating protective sleeve 1, the connecting plate 8 will drive one end of the limiting plate 6 to be inserted into the limiting groove 7 under the elastic force of the reset spring 9. At this time, the limiting bolt 10 is rotated, and one end of the limiting bolt 10 will enter the limiting hole 11 on the limiting plate 6. In this way, the two insulating protective sleeves 1 and the connecting terminal 2 can be connected and fixed together. Rotating the connecting ring 5 and the fixing ring 3 will protect the connection between the two insulating protective sleeves 1, and the two sealing gaskets 4 will make the connection between the insulating protective sleeve 1 and the fixing ring 3 more sealed and waterproof.

[0032] The utility model protects the connection between the connecting terminal 2 and the cable inside by using a fixing ring 3 and two insulating protective sleeves 1, and has a good waterproof protection effect. The connection process between the two insulating protective sleeves 1 is also relatively simple and convenient, and the connection is relatively firm. This embodiment specifically solves the problem in the prior art that when cables are connected using cable connectors, the ends of the two cables are generally connected together using connecting terminals, and then the outside of the connecting terminals are wrapped with insulating tape. This connection method does not provide good protection for the connection and the connection process is also relatively troublesome.

[0033] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
