[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0027] See also Figure 1 The utility model provides a technical solution: a new type of wiring terminal, including a wiring terminal 10, a connector 20 fixed on the left and right sides of the wiring terminal 10, and a connecting cable 30 arranged on the connector 20, a buffer component for preventing the connecting cable 30 from breaking is provided on the connector 20, and the buffer component can prevent the connection between the connecting cable 30 and the connector 20 from breaking when subjected to a pulling force, and a sealing component for improving the waterproof effect of the wiring terminal 10, and the sealing component can improve the waterproof effect of the wiring terminal 10, and can prevent water from entering the interior of the wiring terminal 10 when the wiring terminal 10 is used in an environment with high humidity, thereby affecting its normal use.

[0028] See also Figure 2 The buffer assembly includes a movable ring 40 rotatably arranged at the joint 20, multiple springs 4001 arranged on the inner side of the movable ring 40, and a fixing part 4003 arranged at the other end of the spring 4001. The number of springs 4001 and fixing parts 4003 is the same, and the fixing parts 4003 are designed in an arc shape. The number of fixing parts 4003 is at least four. The multiple fixing parts 4003 are tightly fitted with the connecting cable 30. When the connecting cable 30 is dragged or pulled by external force, the spring 4001 can act as a buffer for the connecting cable 30. At the same time, the movable ring 40 can rotate to prevent the connecting cable 30 from rubbing against the connector 20, which may cause the connection to break, thereby increasing safety hazards.

[0029] In this embodiment, multiple support plates 4002 are fixed on one side of the fixing member 4003, and the two ends of the spring 4001 are respectively fixed between the support plate 4002 and the movable ring 40. The contact surface between the support plate 4002 and the spring 4001 is a plane, which can make the force on the spring 4001 more uniform.

[0030] It should be noted that the number of support plates 4002 is the same as the number of fixing parts 4003, and multiple springs 4001 are distributed equidistantly on the inner side of the movable ring 40. The fixing parts 4003 are made of soft silicone material. Under the action of the elastic potential energy of the springs 4001, the fixing parts 4003 wrap and fix the connecting cable 30.

[0031] See also Figure 3-4The sealing assembly includes a fixed ring 4004 arranged on one side of the movable ring 40, a sealing member 4005 arranged inside the fixed ring 4004, a plurality of sealing grooves 4006 opened on one side of the sealing member 4005, a rotating member 50 arranged on one side of the sealing member 4005, a threaded member 5001 arranged on one side of the rotating member 50, the threaded member 5001 can be rotated by the rotating member 50 and fixed to the fixed ring 4004, a sealing ring 5005 arranged at one end of the threaded member 5001 and a plurality of sealing blocks 5006 arranged on one side of the sealing ring 5005. The use of the sealing ring 5005 and the sealing block 5006 in combination can improve the waterproof effect of the terminal block 10.

[0032] In this embodiment, one side of the threaded member 5001 is rotatably connected to a connecting member 5002, and a plurality of extrusion blocks 5003 are provided on one side of the connecting member 5002. When the connecting member 5002 is pushed to move to the inner side of the fixing ring 4004, one side of the extrusion block 5003 squeezes the fixing member 4003, thereby increasing the distance between the plurality of fixing members 4003, making it easier to insert the connecting cable 30 into the interior of the terminal block 10. The other end of the plurality of extrusion blocks 5003 is fixed with a connecting ring 5004.

[0033] It should be emphasized that the sealing ring 5005 is fixed to the outside of the connecting member 5002, the number of the extrusion blocks 5003 is the same as the number of the fixing members 4003, the extrusion blocks 5003 and the fixing members 4003 are made of the same material, and the multiple extrusion blocks 5003 are respectively located between two adjacent fixing members 4003, and the extrusion blocks 5003 are designed in a fan shape. The length of the extrusion block 5003 close to the connecting ring 5004 is greater than the distance between the two adjacent fixing members 4003, and the length of the extrusion block 5003 close to the connecting member 5002 is less than the distance between the two adjacent fixing members 4003. When the connecting member 5002 is pushed to move to the fixing ring 4004, one side of the extrusion block 5003 squeezes the fixing part 4003 to increase the distance between the multiple fixing parts 4003. At this time, the connecting cable 30 can be inserted into the interior of the terminal 10 through the rotating part 50, and then continue to push until the sealing block 5006 is completely inserted into the sealing groove 4006. At this time, the extrusion block 5003 is located between two adjacent fixing parts 4003 and does not contact the fixing part 4003. Since the fixing part 4003 is not squeezed at this time, the fixing part 4003 is tightly attached to the connecting cable 30 under the action of the spring 4001 and fixes the connecting cable 30.

[0034] It can be understood that one side of the inner wall of the fixing ring 4004 is designed to be threaded, and the threaded member 5001 is threadedly connected to one side of the inner wall of the fixing ring 4004. Rotating the rotating member 50 can fix the threaded member 5001 and the fixing ring 4004. In this process, the sealing block 5006 is completely pushed into the sealing groove 4006.

[0035] Finally, the number of sealing blocks 5006 and sealing grooves 4006 is the same. The sealing blocks 5006 are inserted into the sealing grooves 4006 and matched with the gap therein. The sealing ring 5005 fits with one side of the sealing member 4005. When the sealing block 5006 is inserted into the sealing groove 4006 and matched with the sealing ring 5005, the waterproof effect of the terminal block 10 can be improved to prevent the terminal block 10 from being immersed in water when used in an environment with high humidity.

[0036] Specifically, the working principle of this new terminal block is as follows:

[0037] When in use, first push the connecting piece 5002 to move to the inner side of the fixing ring 4004. At this time, one side of the extrusion block 5003 squeezes the fixing piece 4003 to increase the distance between the multiple fixing pieces 4003. Then, the connecting cable 30 is inserted into the interior of the terminal 10 through the rotating piece 50. Then, the rotating piece 50 can be rotated to fix the threaded piece 5001 and the fixing ring 4004. During this process, the sealing block 5006 is completely pushed into the sealing groove 4006. At this time, the extrusion block 5003 is located between two adjacent fixing pieces 4003 and does not contact the fixing piece 4003. Since the fixing piece 4003 is not squeezed at this time, the fixing piece 4003 is tightly attached to the connecting cable 30 under the action of the spring 4001 and fixes the connecting cable 30.

[0038] It should be noted that the specific models and specifications of the terminal block 10, connector 20, connecting cable 30, movable ring 40, spring 4001, fixing part 4003, fixing ring 4004, seal 4005, rotating part 50, threaded part 5001, extrusion block 5003, sealing ring 5005, and sealing block 5006 need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
