[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-6 , including: a protective cover upper part 1, a protective cover lower part 2 arranged below the protective cover upper part 1, and a crimping head inner groove 3 opened on the concave surface of the protective cover lower part 2. The protective cover upper part 1 and the crimping head inner groove 3 are arranged opposite to each other, and the crimping head inner groove 3 is arranged on the surface of the protective cover upper part 1 and the protective cover lower part 2. After the concave surfaces of the protective cover upper part 1 and the protective cover lower part 2 are combined, an inner cylinder is formed. At the same time, the inner diameter of the crimping head inner groove 3 after combination is larger than the inner diameter of the inner cylinder, so that the cable connector can be disposed in the cavity of the crimping head inner groove 3. The concave surfaces of the protective cover upper part 1 and the protective cover lower part 2 are provided with arc-shaped grooves, and rubber strips 4 are inserted into the arc-shaped grooves. After the cables at both ends are connected at the inner groove 3 of the crimping joint, the cable surface applies pressure to the rubber strips 4 to improve the sealing effect. Positioning strips 8 are symmetrically fixed at the lower end of the protective cover upper part 1, and a positioning slot 9 that is plugged in and adapted to the positioning strip 8 is provided on the top of the protective cover lower part 2. By plugging the positioning strip 8 into the positioning slot 9, the assembly accuracy and stability of the protective cover upper part 1 and the protective cover lower part 2 are improved.

[0028] Also includes:

[0029] The positioning pin 12 is fixedly arranged at the lower end of the protective cover upper part 1; it is a cylindrical structure, and is provided with four groups of rectangular distributions. The positioning socket 11 is opened at the upper end of the protective cover lower part 2, and the positioning pin 12 is plugged and adapted with the positioning socket 11. When the protective cover upper part 1 and the protective cover lower part 2 are combined, the positioning pin 12 is completely inserted into the hole of the positioning socket 11, and a transverse tie rod 14 is arranged below the hole of the positioning socket 11, and a circular groove is arranged outside the transverse tie rod 14 so that the transverse tie rod 14 can move along the circular groove, and the limiting transverse groove part 13 is horizontally opened inside the positioning pin 12; a limiting transverse baffle 15 that can move horizontally along the groove of the limiting transverse groove part 13 is fixed on the top of the transverse tie rod 14, and the movement of the transverse tie rod 14 in the circular groove will drive the fixedly connected limiting transverse baffle 15 to move. After the positioning pin 12 is completely inserted into the hole of the positioning socket 11, the limiting transverse baffle 15 is aligned with the limiting transverse groove part 13. At this time, moving the cross tie rod 14 can make the limiting cross bar 15 snap into the hole of the limiting cross groove 13, so that the positioning pin 12 cannot be separated from the hole of the positioning socket 11, thereby completing the fixation of the protective cover upper part 1 and the protective cover lower part 2, and improving the protection of the cable crimping joint.

[0030] The surface of the protective cover lower part 2 is provided with a linear groove, in which a positive and negative threaded screw 5 is installed. The positive and negative threaded screw 5 is externally meshed and connected with a side pressing plate 6, which fits the intersection of the protective cover lower part 2 and the inner groove 3 of the crimping head. The positive and negative threaded screw 5 extends outward through the protective cover lower part 2, and a closing cylinder 7 is provided on the surface of the protective cover lower part 2 and is sleeved on the outside of the positive and negative threaded screw 5. A sealing kit 10 is threadedly installed on the closing cylinder 7. The positive and negative threaded screw 5 is operated by an external tool to rotate the positive and negative threaded screw 5, so that the meshing side pressure plate 6 moves radially along the groove of the positive and negative threaded screw 5, so that the two groups of side pressure plates 6 are synchronously displaced, and the side pressure is applied to the crimping joint in the inner groove 3 of the crimping joint to improve the stability of the crimping joint. Since the side pressure plate 6 is fixed to one end of the transverse tie rod 14, it will synchronously drive the transverse tie rod 14 to move. After the assembly is completed, the sealing of the positive and negative threaded screw 5 is completed by threading the sealing kit 10 on the outside of the closing cylinder 7.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
