[0030] Figures 1 to 3 This invention illustrates an embodiment of the cable conductor connection device. The cable conductor connection device of this embodiment includes a male connector 1 and a female connector 2. One end of the male connector 1 and the female connector 2 are fixedly connected by a fixing bolt 3. The other end of both the male connector 1 and the female connector 2 is provided with a insertion hole 4 for inserting a cable conductor and a locking fastener 5 for securing the cable conductor. The male connector 1 and the female connector 2 are respectively fitted with a male insulating shell 6 and a female insulating shell 7. The male insulating shell 6 and the female insulating shell 7 are detachably connected, and the opposite ends of the male insulating shell 6 and the female insulating shell 7 are respectively provided with a first inlet / outlet hole 62 and a second inlet / outlet hole 72. The first inlet / outlet hole 62 and the second inlet / outlet hole 72 are axially aligned with the corresponding insertion hole 4.

[0031] Cable connection process: First, the ends of the two cables to be connected pass through the first inlet / outlet hole 62 and the second inlet / outlet hole 72 respectively into the male plug insulation shell 6 and the female plug insulation shell 7; second, the conductors (conductive cores with the outer insulation layer removed) of the ends of the two cables to be connected are inserted into the insertion holes 4 of the male plug connector 1 and the female plug connector 2 respectively, and locked and fixed by the locking fastener 5; then, the male plug connector 1 and the female plug connector 2 are fixedly connected by the fixing bolt 3; finally, the male plug insulation shell 6 and the female plug insulation shell 7 are fixedly connected, and waterproof glue can be applied between the first inlet / outlet hole 62 and the second inlet / outlet hole 72 and the cable to improve waterproof sealing.

[0032] This cable connector has the following features: First, the male connector 1 and the female connector 2 are fixedly connected by fixing bolts 3, and the connection process does not require relative rotation, thus preventing cable twisting and damage. Second, the wire is fixed by the combination of the insertion hole 4 and the locking fastener 5, resulting in a simple structure and low manufacturing cost. Third, the male connector 1 and the female connector 2 are protected by the male connector insulating shell 6 and the female connector insulating shell 7, so that the connection between the wire and the insertion hole 4 is located inside the male connector insulating shell 6 and the female connector insulating shell 7, improving the waterproof sealing and safety of the connection.

[0033] Furthermore, in this embodiment, as Figure 1 As shown, the locking component 5 is a locking screw, which passes through the side wall of the insertion hole 4 and is threadedly connected to the side wall of the insertion hole 4. Tightening the locking screw secures the wire to the conductor, making operation convenient. Specifically, a threaded hole passes through the side wall of the insertion hole 4, and the locking screw is threadedly connected to the threaded hole.

[0034] Furthermore, in this embodiment, each insertion hole 4 has multiple locking screws on its sidewall, and these screws are spaced apart along the axial direction of the insertion hole 4. The wire is secured together by multiple locking screws, improving the stability of the connection.

[0035] Furthermore, in this embodiment, a washer 41 is provided at one end of the locking screw that extends into the insertion hole 4. Each locking screw may have a washer 41 at one end that extends into the insertion hole 4. Of course, all locking screws on the side wall of the insertion hole 4 may also be connected to a washer 41. The locking screw and the washer 41 can be rotated together (rotational connection does not affect the tightening operation of the locking screw). By pressing the wire with the washer 41, the pressing area can be increased, thereby improving the pressing and fixing effect.

[0036] Furthermore, in this embodiment, the opposite ends of the male connector 1 and the female connector 2 are respectively provided with an axial groove 11 and an axial pin 21, with the axial pin 21 inserted into the axial groove 11. The opposite ends of the male connector 1 and the female connector 2 are engaged through the axial groove 11 and the axial pin 21, thereby improving the overall connection strength.

[0037] Furthermore, in this embodiment, the cross-section of the axial locking post 21 is circular or polygonal, and the shapes of the axial locking groove 11 and the axial locking post 21 are adapted to each other.

[0038] Furthermore, in this embodiment, the outer walls of the male connector 1 and the female connector 2 are respectively provided with a first outer protruding ring 12 and a second outer protruding ring 22, and the fixing bolt 3 connects the first outer protruding ring 12 and the second outer protruding ring 22. The first outer protruding ring 12 and the second outer protruding ring 22 are equivalent to connecting flanges, and are connected by the fixing bolt 3, which is convenient for operation. Preferably, the first outer protruding ring 12 and the second outer protruding ring 22 are coaxial, and the axial direction of the fixing bolt 3 is parallel to the axial direction of the first outer protruding ring 12 and the second outer protruding ring 22.

[0039] Furthermore, in this embodiment, multiple fixing bolts 3 are provided, arranged at intervals around the center of the first outer convex ring 12 and the second outer convex ring 22. Preferably, each fixing bolt 3 is evenly spaced around the center of the first outer convex ring 12 and the second outer convex ring 22 to improve the connection effect.

[0040] Furthermore, in this embodiment, as Figure 1 As shown, a first connecting ring 61 and a second connecting ring 71 are respectively provided on the outer walls of the male insulating shell 6 and the female insulating shell 7. The first connecting ring 61 and the second connecting ring 71 are fixedly connected by a plurality of connecting bolts 8, which are arranged at intervals around the center of the first connecting ring 61 and the second connecting ring 71. The first connecting ring 61 and the second connecting ring 71 also function as connecting flanges, and are connected by connecting bolts 8 for convenient operation. Preferably, the first connecting ring 61 and the second connecting ring 71 are coaxial, and the axial direction of the connecting bolts 8 is parallel to the axial direction of the first connecting ring 61 and the second connecting ring 71.

[0041] Furthermore, in this embodiment, the end of the female insulating shell 7 facing the male insulating shell 6 has a mating sleeve 63. The mating sleeve 63 is inserted into the male insulating shell 6 and fits against the inner wall of the male insulating shell 6. This increases the mating area between the female insulating shell 7 and the male insulating shell 6, which is beneficial for improving waterproof sealing. Waterproof adhesive can also be provided between the mating sleeve 63 and the inner wall of the male insulating shell 6 to further improve waterproof sealing.

[0042] Furthermore, in this embodiment, both the male connector 1 and the female connector 2 are cylindrical and coaxial, and are coaxial with the axial retaining post 21, the axial retaining groove 11, the first outer protruding ring 12, the second outer protruding ring 22, the first connecting ring 61, the second connecting ring 71, the first inlet / outlet hole 62 and the second inlet / outlet hole 72.

[0043] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
