Description

Technical Field

[0001] The invention relates to the technical field of connecting terminals, in particular to a tapered press-fit cable connecting terminal. Background Art

[0002] As we all know, mineral cable terminals are also called wire noses. They are often used for cable end connection and splicing. They can make the connection between cables and electrical appliances more secure and safer. They are very common connection parts in the field of cable installation. The function of cables is to transmit electricity and signals, or realize electromagnetic energy conversion. They are electrical products. There are many types and specifications. First of all, when transmitting electricity, you can choose a set of cables or power cables. If it is used to transmit signal information, you can choose TV cables or optical fiber cables, as well as local telephone cables.

[0003] So from a popular perspective, cables are indispensable in our daily life, including construction projects, agricultural research, space, and ocean fields.

[0004] When two cables need to be connected, a terminal block is usually used. When using the existing terminal block, the terminal block needs to be fixed at the ends of the two cables with screws. When used for a long time, the screw fixing part is easy to loosen, which will cause a circuit break at the terminal block, affecting the stability of the cable when in use. Moreover, when connecting the two cables, it is inconvenient to position the two cables at the same time, which will cause inconvenience in wiring and affect the efficiency of cable wiring.

The bottom end of the adapter block 14 is provided with a guide groove 11 connected to the docking groove 8, the upper end of the adapter block 14 is provided with a lifting rod 15 that penetrates the guide groove 11, and the top of the lifting rod 15 is provided with a positioning block 10, the positioning block 10 cooperates with the positioning groove 20, and a card slot 19 is provided on the inner wall of the positioning groove 20, and grooves are provided on both sides of the positioning block 10, and a spring is provided inside the groove, one end of the spring is fixed inside the groove, and a card block 12 is provided at the other end of the spring, and the card block 12 cooperates with the card slot 19, and the pressure plate 2 is fixed on the positioning block 10. The top of the two pressing plates 2 is connected by a cross bar. When the present structure is needed to dock two cables, the wiring terminals of the cables are respectively inserted into the two ends of the docking slot 8, and then the pressing plate 2 is pressed. At this time, the two positioning blocks 10 and the lifting rod 15 will synchronously lower the pressing plate 13 inside the docking slot 8, so that the pressing plate 13 clamps and fixes the wiring terminals of the two cables inside the docking slot 8. When the positioning block 10 is completely inside the positioning slot 20, the spring will provide an elastic force to the clamping block 12, so that the clamping block 12 enters the inside of the clamping slot 19. Through the cooperation between the card block 12 and the card slot 19, a limiting effect will be provided to the positioning block 10 inside the positioning slot 20. At this time, the positioning block 10 will be fixed inside the positioning slot 20, the lifting rod 15 will be fixed inside the guide slot 11, and the clamping plate 13 will be fixed inside the docking slot 8, so that the clamping plate 13 can fix the wiring terminals of the two cables inside the docking slot 8. At this time, the two adapter blocks 14 will be connected in series through the adapter rod 18. At this time, the two cables will transmit electricity through the adapter rod 18. This structure is a disposable product, such as Figure 4As shown, the card block 12 is a trapezoidal structure, the top of the card block 12 is a plane, and the lower end of the card block 12 is an inclined surface. Therefore, when the card block 12 enters the inside of the card slot 19, even if a pulling force is applied to the pressure plate 2 at this time, the positioning block 10 will not be separated from the positioning slot 20, so that the clamping plate 13 can clamp and position the cable more firmly inside the docking slot 8, thereby further improving the stability of the structure when in use. The material of the shell 1, the lifting rod 15 and the positioning block 10 are all high-temperature resistant hard plastic. After the two cables are connected, the shell 1 can be wrapped with tape. The structure is simple and easy to operate. The docking point of the cable is not easy to loosen, avoiding the phenomenon of circuit breakage at the shell 1, thereby improving the stability of the cable when in use, and anti-slip grooves are provided between the inner wall of the docking slot 8 and the outer wall of the clamping plate 13.

[0025] When the present structure is in use, there is a lack of a guiding structure between the connection point of the cable and the docking groove 8, which will affect the smoothness of the cable during wiring. The two ends of the shell 1 are provided with a threaded groove 7 and a tapered sleeve 9, and one end of the tapered sleeve 9 is provided with a threaded ring that cooperates with the threaded groove 7. The tapered sleeve 9 can be made of soft conductive metal here. The tapered sleeve 9 can provide a guiding structure between the connection point of the cable and the docking groove 8, thereby improving the smoothness of the cable during wiring. Moreover, the mutual cooperation between the threaded ring and the threaded groove 7 makes it easy to position the tapered sleeve 9 at both ends of the shell 1, making the tapered sleeve 9 more convenient to install. After the cable wiring is completed, the tapered sleeve 9 is pressed with the jaws to wrap the cable.

[0026] When the present structure is in use, there is a lack of a guide structure between the pressing plate 2 and the shell 1, which will affect the smoothness of the pressing plate 2 when being pressed. A plurality of positioning holes 3 are provided at the upper end of the shell 1, and the positioning holes 3 are located on the peripheral side of the positioning groove 20. Positioning rods 4 inserted into the positioning holes 3 are provided at the four corners of the pressing plate 2, and through holes 5 are provided on the positioning rods 4. Screws 6 inserted into the shell 1 and passing through the through holes 5 are provided at both ends of the shell 1. When the pressing plate 2 is pressed, the positioning rods 4 will move inside the positioning holes 3. Through the mutual cooperation between the positioning rods 4 and the positioning holes 3, a guide structure can be provided between the pressing plate 2 and the shell 1, thereby improving the smoothness of the pressing plate 2 when being pressed. When the pressing plate 2 contacts When the shell 1 is in use, the screw 6 is inserted into the shell 1, and the screw 6 and the through hole 5 cooperate with each other to provide a limiting effect on the positioning rod 4 in the positioning hole 3, so that the pressure plate 2 is more firmly fixed on the upper end of the shell 1, thereby improving the stability of the structure when in use. Before the use of the structure, the screw 6 is also located inside the shell 1, and the screw 6 at this time will be located below the positioning rod 4 to prevent the pressure plate 2 from being accidentally touched during the transportation of the structure. Instead, the positioning block 10 is inserted into the positioning groove 20, thereby further improving the practicality of the structure. As for the material of the conical sleeve 9, it can be made according to the material of the cable, such as copper or aluminum.
