Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of terminals, in particular to a self-locking plug-in terminal. Background Art
[0002] The terminal block is the connection end in the circuit. It is divided into single-hole, double-hole, socket and hook according to different types. It is mainly used to transmit signals or conduct electricity. The plug-in terminal is a type of terminal. It is widely used in the electronics industry. The terminal end is usually equipped with multiple sets of pins. After plugging, each pin can be accurately positioned in the corresponding pin hole, which is suitable for signal transmission.
[0003] According to the "A self-locking plug-in terminal (publication number: CN 220209469 U; application number: 202320782793.1)" published on the patent website, the above application optimizes the problem that "most of the current connecting terminals are plug-in shaped, relying on friction or a slight elastic protrusion to fix the two terminals, but this fixing method is very unreliable. Once the wire is subjected to tension in the connection direction, it will cause the connecting terminals to fall off. The few connecting terminals use screws to fix the terminals. This method is very reliable, but it is difficult to disassemble and assemble." However, when the connecting structure of the plug-in terminal in the above application is used, it is necessary to keep pressing the 'disassembly button 208' at both ends during installation or disassembly, which is inconvenient for staff to use.

[0025] The present utility model provides a technical solution:
[0026] Embodiment 1
[0027] Combined with Figures 1 to 4, A self-locking plug-in terminal, comprising a base 3, a card seat 31 fixedly connected to the top of the base 3, a plug-in pin 32 fixedly connected to the inside of the top of the card seat 31, a main body structure 41 clamped inside the top of the card seat 31, the main body structure 41 being clamped outside the card seat 31, a joint 4 fixedly connected to the top of the main body structure 41, a fixing mechanism 1 arranged inside the card seat 31, and a positioning mechanism 2 arranged outside the outer circle of the card seat 31.
[0028] The fixing mechanism 1 includes a positioning component 11 and a reset component 12. The positioning component 11 is arranged inside the card seat 31, and the reset component 12 is arranged inside the positioning component 11.
[0029] The positioning component 11 includes a clamping plate 1101. The clamping plate 1101 is fixedly connected to the bottom of the joint 4 at the four corner positions outside the main body structure 41. The clamping plate 1101 is clamped inside the top of the card seat 31. A clamping rod 1102 is clamped inside the clamping plate 1101. The clamping rod 1102 is slidably connected inside the card seat 31. The reset component 12 includes a sliding plate 1201. The sliding plate 1201 is fixedly connected to the outside of the clamping rod 1102. The sliding plate 1201 is slidably connected inside the card seat 31. A reset spring 1202 is fixedly connected to the inner side of the sliding plate 1201. The reset spring 1202 is sleeved on the outer circle of the clamping rod 1102.
[0030] Furthermore: The staff only needs to rotate the rotating ring 2101 to squeeze the clamping rod 1102 inward, so that the clamping rod 1102 is clamped inside the clamping plate 1101 to complete the fixing process between the card seat 31 and the joint 4. After the rotation of the rotating ring 2101 releases the extrusion of the clamping rod 1102, the sliding plate 1201 will drive the clamping rod 1102 to move outward automatically under the action of the reset spring 1202 to disengage from the connection with the clamping plate 1101, enabling the staff to complete the installation and disassembly of the card seat 31 and the joint 4 only by rotating the rotating ring 2101 without additional operations, which is simple to operate and convenient for the staff to use.
[0031] Embodiment 2
[0032] Refer to Figures 1 to 6 , and on the basis of Embodiment 1, it is further obtained that the positioning mechanism 2 includes an extrusion component 21 and a reinforcement component 22. The extrusion component 21 is rotatably connected to the outer circle of the card seat 31, and the reinforcement component 22 is arranged inside the extrusion component 21.
[0033] The extrusion assembly 21 includes a swivel ring 2101 which is rotatably connected to the outer ring of the clamping seat 31. A notch 2102 is formed on the outer side of the swivel ring 2101. Arc-shaped rounded corners 2103 are formed on the left and right sides of the notch 2102. A groove 2104 is formed on the outer ring of the swivel ring 2101. The reinforcement assembly 22 includes a sliding piece 2201 which is slidably connected to the inside of the swivel ring 2101. A compression spring 2202 is fixedly connected to the outer side of the sliding piece 2201. A clamping block 2203 is fixedly connected to the inner side of the sliding piece 2201, and the clamping block 2203 is clamped in the outer ring of the clamping seat 31.
[0034] Furthermore: Through the arc-shaped rounded corners 2103 formed on the left and right sides of the notch 2102 of the swivel ring 2101, the swivel ring 2101 will not get stuck when rotating to extrude the clamping rod 1102, making the rotation operation of the swivel ring 2101 smoother. After the swivel ring 2101 rotates to complete the extrusion of the clamping rod 1102, the sliding piece 2201 will drive the clamping block 2203 to be clamped in the outer side of the clamping seat 31 under the action of the compression spring 2202 to complete the positioning of the swivel ring 2101, so that the swivel ring 2101 will not rotate by itself without external force, ensuring the extrusion of the clamping rod 1102 by the swivel ring 2101 and increasing the stability after the joint 4 is installed.
[0035] During the actual operation process, when this device is used and when the joint 4 needs to be installed, the staff first rotates the swivel ring 2101 to align the notch 2102 with the clamping rod 1102. Then the staff inserts the main body structure 41 into the top of the clamping seat 31 so that the bottom of the joint 4 is in contact with the top of the clamping seat 31. Then the staff rotates the swivel ring 2101 again. The swivel ring 2101 rotates to extrude the clamping rod 1102 through the transition of the arc-shaped rounded corners 2103. The swivel ring 2101 extrudes the clamping rod 1102 inward so that the clamping rod 1102 is clamped in the clamping plate 1101 to complete the fixation of the main body structure 41. At the same time when the swivel ring 2101 completes the extrusion of the clamping rod 1102, the clamping block 2203 is aligned with the hole correspondingly formed on the outer side of the clamping seat 31. At this time, the sliding piece 2201 drives the clamping block 2203 to be clamped in the outer side of the clamping seat 31 under the action of the compression spring 2202 to complete the positioning of the swivel ring 2101. At this time, the fixation work of the joint 4 is completed.
[0036] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
