[0015] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept to be protected by the present invention.

[0016] like Figures 1 to 3 As shown, a compression cable connector comprises two sleeves 1, one side of the two sleeves 1 is detachably connected, the other side of the two sleeves 1 is provided with a plurality of elastic pressing plates 2, the outer side of the elastic pressing plates 2 is provided with a guide protrusion 3, and the guide protrusion 3 is provided with a guide surface 4, the outer side of the sleeve 1 is threadedly connected with a guide cylinder 5, and the guide cylinder 5 can be moved along the sleeve 1 toward the guide protrusion 3 by rotating the guide cylinder 5.

[0017] The working principle of the compact cable connector described in the utility model is achieved through the cooperation between the sleeve 1, the guide cylinder 5 and the elastic pressing piece 2. Figures 1 to 3As shown, the staff puts the sleeve 1 on the end position of the cable to be connected, and then joins the two sections of the cable. The two sleeves 1 connect and wrap the joint of the two sections of the cable. Then the staff rotates the guide cylinder 5 on the sleeve 1, and the guide cylinder 5 moves along the sleeve 1 and abuts against the guide protrusion 3 of the elastic pressing piece 2. The guide cylinder 5 drives the guide protrusion 3 to swing toward the inside of the elastic pressing piece 2 through the guide surface 4. As the guide protrusion 3 swings, the elastic pressing piece 2 bends toward the cable, so that multiple elastic pressing pieces 2 cooperate to compress the cable, thereby completing the connection and installation of the sleeve 1 and the cable. Compared with traditional cables, the compact cable connector can drive multiple elastic pressing pieces 2 to bend and clamp the cable through the guide cylinder 5, thereby improving the connection stability of the two sections of the cable to prevent the cable from being easily separated due to external force.

[0018] Specifically, an internal threaded sleeve 6 is provided on one side of one of the sleeves 1, and an external threaded ring 7 is provided on one side of the other sleeve 1, and the internal threaded sleeve 6 is threadedly connected to the external threaded ring 7 so that the two sleeves 1 are detachably connected, wherein a plurality of elastic pressing sheets 2 are evenly arranged on the circumference of the sleeve 1, the guide protrusion 3 is a trapezoidal table-like structure, and a horizontal extension portion 8 is provided on the side of the guide protrusion 3 facing the sleeve 1, and further, a bending portion 9 adjacent to the guide protrusion 3 is provided on one end of the elastic pressing sheet 2 away from the sleeve 1, and the guide surface 4 is inclined outward in a direction away from the horizontal extension portion 8, such as Figures 1 to 3 As shown, the two sleeves 1 are detachably connected for easy disassembly and assembly, the guide surface 4 of the guide protrusion 3 is inclined, the guide cylinder 5 contacts the guide surface 4 to drive the guide protrusion 3 to swing, the guide protrusion 3 drives the elastic pressing plate 2 to undergo elastic deformation and bend toward the cable, the elastic pressing plate 2 can be made of elastic rubber material, the elastic pressing plate 2 is evenly arranged around the circumference, the gap between the elastic pressing plates 2 can allow the elastic pressing plates 2 to bend and swing, so that multiple elastic pressing plates 2 can cooperate to clamp the cable, thereby improving the connection stability of the cable joint, the bending portion 9 can adopt multiple openings, so that the end of the elastic pressing plate 2 can bend again after it abuts against the cable, thereby increasing the contact area between the end of the elastic pressing plate 2 and the cable, thereby improving the clamping degree of the elastic pressing plate 2 and the connection stability of the cable.

[0019] Furthermore, the outer side of the sleeve 1 and the inner side of the guide cylinder 5 are provided with threaded sections, and the sleeve 1 and the guide cylinder 5 are threadedly connected through the threaded sections, wherein the guide cylinder 5 is provided with a pressure ring 10 on the side facing the guide protrusion 3, and the inner side of the pressure ring 10 is flush with the horizontal top surface of the plurality of horizontal extensions 8, such as Figures 1 to 3As shown, rotating the guide cylinder 5 can make the guide cylinder 5 move along the sleeve 1, and the pressure ring 10 moves with the guide cylinder 5. The pressure ring 10 passes through the horizontal extension part 8 and abuts against the guide surface 4 of the guide protrusion 3, so that the pressure ring 10 drives the guide protrusion 3 to swing. The horizontal extension part 8 can guide the pressure ring 10 so that the pressure ring 10 drives multiple guide protrusions 3 to swing at the same time, which is convenient for the staff to operate and use.
