Description

Technical Field

[0001] The utility model relates to the technical field of terminals, in particular to a terminal accidental collision and dislocation prevention structure. Background Art

[0002] Terminals are the parts that connect batteries to external conductors. In electrical engineering, terminals mostly refer to wiring terminals, also called wiring terminals. They are divided into single-hole, double-hole, socket, hook, etc., and materials include silver-plated copper, zinc-plated copper, copper, aluminum, iron, etc. Their main function is to transmit electrical signals or conduct electricity.

[0003] In electronic devices, terminals are usually used to connect wires or cables to achieve signal transmission or power supply. However, during use, the terminals may be dislocated due to accidental contact or other reasons, resulting in connection failure, which will affect the normal operation of the device or even cause damage to the device. In view of this, we propose a terminal accidental contact anti-dislocation structure. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A terminal accidental collision and anti-dislocation structure comprises a fixed seat, a locking mechanism, and a clamping mechanism. The locking mechanism is arranged inside the fixed seat and is used to lock the terminal to prevent it from falling off due to accidental collision. The clamping mechanism is arranged on the fixed seat and is used to preliminarily fix the terminal, wherein the locking mechanism comprises: a lifting plate, a spring, a fixed block, a bidirectional screw, and a locking block. An inner cavity is opened on the inner wall of the fixed seat, the lifting plate is slidably connected to the inner wall of the inner cavity, the spring is fixedly installed inside the inner cavity and fixedly connected to the lifting plate, the fixed block is fixedly installed at the bottom of the lifting plate, the bidirectional screw is rotatably connected to one side of the fixed block through a bearing, and the locking block is threadedly sleeved on the outer wall of the bidirectional screw and extends through the lifting plate.

[0007] The bidirectional screw rotates, thereby driving the two locking blocks threadedly sleeved on the outer wall of the bidirectional screw to move away from each other until the locking blocks enter deep into the locking groove, thereby completing the fixation of the terminal body.

[0008] Preferably, the clamping mechanism comprises a terminal body, and grooves are provided on both sides of the terminal body. The terminal body can be placed in an inner cavity provided on the inner wall of the fixing seat.

[0009] Preferably, the clamping mechanism further comprises a second spring, the second spring is fixedly mounted on the inner wall of the groove, the inner wall of the groove is slidably connected with a clamping block, and the clamping block is fixedly connected to the second spring. The clamping block squeezes the second spring, thereby moving toward the inner wall of the groove.

[0010] Preferably, a clamping groove is provided on the inner wall of the inner cavity of the fixing seat, and the clamping groove is adapted to the clamping block. The clamping block and the clamping groove are clamped to form a clamping connection, so as to form a preliminary fixation for the terminal body.

[0011] Preferably, a locking groove is provided at the bottom of the terminal body, and the locking groove is adapted to the locking block. The two locking blocks move away from each other until the locking block enters deep into the locking groove.

[0012] Preferably, the inner wall of the inner cavity of the fixing seat is rotatably connected to a worm through a bearing, and the outer wall of the worm is meshedly connected to a worm wheel. By rotating the worm, the worm wheel meshedly connected to the outer wall of the worm is driven to rotate.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. When the terminal body enters the inner cavity of the fixed seat, the locking block will be in the locking groove, and the bottom of the terminal body will squeeze the lifting plate, so that the squeezing spring 1 moves downward, thereby driving all the components on the lifting plate to move. When the card block is connected with the card groove, the bevel gear 2 is meshed with the bevel gear 1, and then the worm can be rotated to drive the worm wheel meshing with the outer wall of the worm to rotate, and then the rotating rod fixedly mounted on the inner wall of the worm wheel is driven to rotate, so that the bevel gear 1 fixedly mounted on the outer wall of the rotating rod is driven to rotate. Through the meshing action of the bevel gear 1 and the bevel gear 2, the bidirectional screw is driven to rotate, thereby driving the two locking blocks with the threaded sleeve on the outer wall of the bidirectional screw to move away from each other until the locking block enters the deep end of the locking groove, thereby completing the fixation of the terminal body, which can prevent dislocation due to accidental contact or other reasons, and ensure the normal operation of the equipment.

[0016] 2. By placing the terminal body in the inner cavity opened on the inner wall of the fixing seat, the clamping block will squeeze the spring 2, thereby moving toward the inner wall of the groove until it reaches the clamping slot, and the clamping block and the clamping slot form a clamping connection, thereby forming a preliminary fixation for the terminal body.

The locking mechanism 21 is arranged inside the fixing seat 1 to lock the terminal to prevent it from falling off due to accidental collision. The clamping mechanism 31 is arranged on the fixing seat 1 to preliminarily fix the terminal, wherein the locking mechanism 21 comprises: a lifting plate 211, a spring 212, a fixing block 213, a bidirectional screw 214, and a locking block 215. An inner cavity is opened on the inner wall of the fixing seat 1, and the lifting plate 211 is slidably connected to the inner wall of the inner cavity. The spring 212 is fixedly installed inside the inner cavity and fixedly connected to the lifting plate 211. The fixing block 213 is fixedly installed at the bottom of the lifting plate 211. The bidirectional screw 214 is rotatably connected to the inner wall of the inner cavity through a bearing. On one side of the fixing block 213, the locking block 215 is threadedly sleeved on the outer wall of the bidirectional screw 214 and extends through the lifting plate 211. A locking groove 5 is provided at the bottom of the terminal body 311, and the locking groove 5 is adapted to the locking block 215. The two locking blocks 215 move away from each other until the locking block 215 enters deep into the locking groove 5, thereby completing the fixation of the terminal body 311. The inner wall of the inner cavity of the fixing seat 1 is rotatably connected to the worm 6 through a bearing, and the outer wall of the worm 6 is meshed with a worm gear 7. The inner wall of the worm gear 7 is fixedly sleeved with a rotating rod 8, and the top of the outer wall of the rotating rod 8 is fixedly sleeved with a bevel gear 1 9, and the outer wall of the bevel gear 1 9 is meshed with a bevel gear 2 10, and the bevel gear 2 10 is fixedly sleeved on the outer wall of the bidirectional screw 214.

[0025] When the locking block 314 is engaged with the locking groove 4, the bevel gear 210 is meshed with the bevel gear 19, and then the worm 6 can be rotated to drive the worm wheel 7 meshing with the outer wall of the worm 6 to rotate, thereby driving the rotating rod 8 fixedly sleeved on the inner wall of the worm wheel 7 to rotate, so that the bevel gear 19 fixedly sleeved on the outer wall of the rotating rod 8 is rotated, and the meshing action of the bevel gear 19 and the bevel gear 19 10 makes the bidirectional screw 214 rotate, thereby driving the two locking blocks 215 threadedly sleeved on the outer wall of the bidirectional screw 214 to move away from each other until the locking block 215 enters the deep end of the locking groove 5, thereby completing the fixation of the terminal body 311, and preventing dislocation due to accidental contact or other reasons.

[0026] like Figure 1-4 As shown, the clamping mechanism 31 includes a terminal body 311, and grooves 312 are provided on both sides of the terminal body 311.
