DETAILED DESCRIPTION
[0018] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
[0019] Example: See Figure 1 - Figure 6 The utility model provides a technical solution: a cable terminal, comprising: an end 1, the bottom end of the end 1 is fixedly connected to a wiring tube 21; a wiring device 2, the outer wall of the top of the wiring device 2 is fixedly connected to the bottom end of the end 1; the wiring device 2 also includes an extrusion ring 22, the side wall outside the wiring tube 21 is provided with a gripping groove 23, the side wall inside the wiring tube 21 is provided with an avoidance groove 24, the inner wall of the wiring tube 21 is slidably connected to an extrusion device 26 through a stage groove 25, and the stage groove 25 is symmetrically opened in the wall of the wiring tube 21, and the side wall inside the wiring tube 21 is fixed. A wrapping device 27 is connected, and the outer wall of the top of the extrusion ring 22 is fixedly connected to the outer wall of the bottom of the wiring tube 21. When the cable passes through the holding groove 23, it will enter the avoidance groove 24 of the wiring tube 21. The inner diameter of the wiring tube 21 in the avoidance groove 24 is smaller, so after the cable enters, it will push the inner diameter component of the wiring tube 21 into the avoidance groove 24. After entering the avoidance groove 24, the pushed interior of the wiring tube 21 returns to the size of the cable diameter, and the inner wall of the pushed wiring tube 21 generates a reaction force due to the extrusion, thereby squeezing the wiring tube 21 to complete the initial positioning.
[0020] The extrusion device 26 includes an extrusion column 261 . A clearance groove 262 is formed on the outer wall of the extrusion column 261 . A blocking disk 263 is fixedly connected to the outer wall of the extrusion column 261 . An elastic ring 264 is fixedly connected to the outer wall of the blocking disk 263 .
[0021] The outer wall of the elastic ring 264 is fixedly connected to the outer wall of the extrusion column 261, and the outer wall of the extrusion column 261 is slidably connected to the inner wall of the wiring tube 21. The elastic ring 264 contacts the inner wall of the wiring tube 21 through the stage groove 25. The user pushes the extrusion columns 261 on both sides of the wiring tube 21. At this time, the extrusion columns 261 move into the interior of the wiring tube 21 under the push of the staff. The blocking plate 263 and the elastic ring 264 cooperate to limit the movement range of the extrusion column 261 on the one hand, and on the other hand, the blocking plate 263 provides a fulcrum for the elastic ring 264 during the deformation process, so that the extrusion device 26 is squeezed and deformed during the pushing process, so that it enters the position of the give way groove 262, thereby allowing the extrusion column 261 to be pushed smoothly. When the deformed elastic ring 264 reaches the position of the stage groove 25, the extrusion of the wiring tube 21 is lost. The elastic force generated by the previous extrusion will act on the elastic ring 264, causing it to enter the stage groove 25, thereby fixing the position of the extrusion device 26.
[0022] The wrapping device 27 includes a fixing ring 271, the side wall of the outer side of the fixing ring 271 is provided with a reserved groove 272, the side wall inside the fixing ring 271 is fixedly connected to the friction ring 274, the outer wall of the friction ring 274 is provided with a spacing groove 273, the outer wall of the fixing ring 271 is fixedly connected to the side wall inside the wiring tube 21, and the outer wall of the bottom of the fixing ring 271 is fixedly connected to the outer wall of the extrusion ring 22. After the cable is fully entered and connected with the terminal 1, force is applied to the extrusion ring 22 from the bottom of the wiring device 2 to deform it and squeeze the reserved groove 272 position of the wrapping device 27. At this time, the fixing ring 271 is squeezed and then lifts up the friction ring 274. At this time, the friction ring 274 that is tilted towards the terminal 1 is pushed out and clamps the cable, increasing the friction force by applying pressure, and then fixing the cable surface for a second time, thereby improving the stability of the cable connection. The provision of the spacing groove 273 and the avoidance groove 24 can also provide a buffer space for the thermal expansion and contraction of the cable, preventing the cable from being damaged by rapid temperature changes.
[0023] Working principle:
[0024] When in use, the terminal 1 of the terminal is used to connect external devices and lines, and the wiring tube 21 located at the bottom of the terminal 1 is connected to the terminal 1. The wiring tube 21 is made of a material with deformation recovery ability to provide space for cable connection;
[0025] During the process of connecting the cable to the terminal, the cable is fixed in position by the components inside the wiring device 2, wherein a squeezing device 26 and a wrapping device 27 are provided to fix the cable multiple times, so that the cable connection is stable;
[0026] The fixing ring 271 is fixed to the inner side wall of the wiring tube 21 to provide support for the friction ring 274. After the cable is inserted into the wiring tube 21 and passes through the extrusion ring 22, the friction ring 274 will contact the cable, wherein the friction ring 274 will increase the friction between the spacing groove 273 and the cable, and the convex part of the friction ring 274 will be squeezed toward the position of the spacing groove 273 through the friction of the cable. At this time, the convex part of the friction ring 274 will fall toward the end 1. When the cable passes through the holding groove 23, it will enter the avoidance groove 24 of the wiring tube 21. The inner diameter of the wiring tube 21 in the avoidance groove 24 is smaller, so after the cable enters, it will push the inner diameter component of the wiring tube 21 into the avoidance groove 24. After the pushed wiring tube 21 enters the avoidance groove 24, it returns to The diameter of the cable is large or small, and the inner wall of the pushed wiring tube 21 generates a reaction force due to the extrusion, thereby squeezing the wiring tube 21 to complete the initial positioning. After the cable is fully entered and connected with the terminal 1, force is applied to the extrusion ring 22 from the bottom of the wiring device 2 to deform it and squeeze the reserved groove 272 position of the wrapping device 27. At this time, the fixing ring 271 is squeezed and then lifts the friction ring 274. At this time, the friction ring 274 facing the terminal 1 is pushed out and clamps the cable, increasing the friction force by applying pressure, and then fixing the cable surface for a second time, thereby improving the stability of the cable connection. At the same time, the setting of the spacing groove 273 and the avoidance groove 24 can also provide a buffer space for the thermal expansion and contraction of the cable, preventing the cable from being damaged by rapid temperature changes.
[0027] When the cable is inserted into the wiring tube 21, the squeezing device 26 is used to ensure that the connection is more stable. The user pushes the squeezing columns 261 on both sides of the wiring tube 21. At this time, the squeezing columns 261 move into the wiring tube 21 under the push of the staff. The blocking plate 263 and the elastic ring 264 cooperate to limit the movement range of the squeezing columns 261 on the one hand, and on the other hand, the blocking plate 263 provides a fulcrum for the elastic ring 264 during the deformation process, so that the squeezing device 26 is squeezed and deformed during the pushing process, so that it enters the position of the give way groove 262, thereby allowing the squeezing column 261 to be pushed smoothly. When the deformed elastic ring 264 reaches the position of the stage groove 25, the squeezing of the wiring tube 21 is lost. The elastic force generated by the squeezing will act on the elastic ring 264, causing it to enter the stage groove 25, thereby fixing the position of the squeezing device 26, so that the squeezing column 261 can apply pressure to the cable, ensuring that the cable is in close contact with the wiring terminal, and improving the stability and reliability of the connection.
