DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0022] Please refer to Figures 1-5 ​​​The tapered press-fit cable terminal block of the present invention includes a housing 1, the interior of which is provided with a mating groove 8. Two wiring assemblies are symmetrically arranged on the housing 1. Each wiring assembly includes a pressure plate 2, a positioning groove 20, and a clamping plate 13. The clamping plate 13 is located inside the mating groove 8 and is located at both ends of the mating groove 8. An adapter block 14 is provided at the upper end of the clamping plate 13. The two adapter blocks 14 are connected by an adapter rod 18. The positioning groove 20 is fixed to the upper end of the housing 1 and is located above the adapter block 14. The bottom end of the adapter block 14 is provided with a guide groove 11 that communicates with the docking groove 8. The upper end of the adapter block 14 is provided with a lifting rod 15 that passes through the guide groove 11. The top end of the lifting rod 15 is provided with a positioning block 10. The positioning block 10 cooperates with the positioning groove 20. The inner wall of the positioning groove 20 is provided with a slot 19. The two sides of the positioning block 10 are provided with grooves. A spring is provided inside the groove. One end of the spring is fixed inside the groove. The other end of the spring is provided with a locking block 12. The locking block 12 cooperates with the slot 19. The pressure plate 2 is fixed to the positioning block 10. At the top, the two pressure plates 2 are connected by a crossbar. When this structure is needed to connect two cables, the cable terminals are inserted into both ends of the docking groove 8, and then the pressure plates 2 are pressed down. At this time, the two positioning blocks 10 and the lifting rod 15 will synchronously lower the clamping plate 13 inside the docking groove 8, so that the clamping plate 13 clamps and fixes the cable terminals inside the docking groove 8. When the positioning block 10 is completely inside the positioning groove 20, the spring will provide a spring force to the locking block 12, so that the locking block 12 enters the locking groove 19. The cooperation between the locking block 12 and the locking slot 19 provides a limiting effect for the positioning block 10 inside the positioning slot 20. At this time, the positioning block 10 is fixed inside the positioning slot 20, the lifting rod 15 is fixed inside the guide slot 11, and the clamping plate 13 is fixed inside the docking slot 8. This allows the clamping plate 13 to fix the terminals of the two cables inside the docking slot 8. Then, the two adapter blocks 14 are connected in series through the adapter rod 18, and the two cables transmit power through the adapter rod 18. This structure is a disposable product. Figure 4As shown, the card block 12 is a trapezoidal structure, the top end of the card block 12 is a plane, and the lower end of the card block 12 is a slope, so when the card block 12 enters the inside of the card slot 19, even if a pulling force is provided to the pressing plate 2, the positioning block 10 will not be separated from the positioning slot 20, and the pressing plate 13 can be more firmly clamped and positioned in the inside of the butt joint groove 8, thereby further improving the stability of the structure during use. The materials of the shell 1, the lifting rod 15, and the positioning block 10 are all high-temperature-resistant hard plastic, which can be used when the two cables are connected. After the two cables are connected, the shell 1 can be wrapped with adhesive tape, which is simple in structure and easy to operate. The butt joint of the cable is not easy to loosen, avoiding the phenomenon of open circuit of the shell 1, thereby improving the stability of the cable during use. In addition, the inner wall of the butt joint groove 8 and the outer wall of the pressing plate 13 are both provided with anti-skid lines.

[0023] In use, the structure lacks a guide structure between the wiring of the cable and the butt joint groove 8, which affects the smoothness of the cable during wiring. Both ends of the shell 1 are provided with a threaded groove 7 and a conical sleeve 9. One end of the conical sleeve 9 is provided with a threaded ring matched with the threaded groove 7. The conical sleeve 9 is made of soft conductive metal. The conical sleeve 9 provides a guide structure between the wiring of the cable and the butt joint groove 8, improving the smoothness of the cable during wiring. Moreover, the threaded ring and the threaded groove 7 are matched with each other, which facilitates the positioning of the conical sleeve 9 at both ends of the shell 1, making the installation of the conical sleeve 9 more convenient. After the cable is connected, the conical sleeve 9 is wrapped around the cable by pressing the conical sleeve 9 with pliers.

[0024] The structure lacks a guide structure between the pressing plate 2 and the shell 1 during use, which affects the smoothness of the pressing plate 2 during pressing. The upper end of the shell 1 is provided with a plurality of positioning holes 3, the positioning holes 3 are located on the side of the positioning groove 20, the four corners of the pressing plate 2 are provided with positioning rods 4 inserted into the inside of the positioning holes 3, the positioning rods 4 are provided with through holes 5, both ends of the shell 1 are provided with screw rods 6 inserted into the inside of the shell 1 and penetrating through the through holes 5. When the pressing plate 2 is pressed, the positioning rod 4 will move inside the positioning hole 3. Through the cooperation of the positioning rod 4 and the positioning hole 3, a guide structure is provided between the pressing plate 2 and the shell 1, thereby improving the smoothness of the pressing plate 2 during pressing. When the pressing plate 2 contacts the shell 1, the screw rod 6 is inserted into the inside of the shell 1. Through the cooperation of the screw rod 6 and the through hole 5, a limiting action is provided for the positioning rod 4 inside the positioning hole 3, thereby making the pressing plate 2 more firmly on the upper end of the shell 1, improving the stability of the structure during use. Moreover, before use, the screw rod 6 is also located in the inside of the shell 1, and at this time the screw rod 6 will be located below the positioning rod 4, preventing the pressing plate 2 from being inserted into the inside of the positioning groove 20 due to accidental contact during transportation, thereby further improving the practicality of the structure. As for the material of the conical sleeve 9, it can be made of copper or aluminum according to the material of the cable.

[0025] Further, the two sides of the pressing plate 13 are provided with sliding blocks 16, and the inner wall of the butt joint groove 8 is provided with sliding grooves 17 matched with the sliding blocks 16. When the pressing plate 13 moves in the butt joint groove 8, the sliding block 16 will slide in the sliding groove 17. Through the cooperation of the sliding block 16 and the sliding groove 17, a guide structure is provided for the pressing plate 13 in the butt joint groove 8, thereby making the pressing plate 13 move more smoothly in the butt joint groove 8.

[0026] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
