Therefore, there is an urgent need for a weak-current wiring terminal to solve the above problems. Summary of the Utility Model

All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0023] Referring to Figures 1-5 , the present utility model provides a weak current wiring terminal, including:

[0024] The first connecting block 1 is fixedly connected with an insertion block 2 on the inner wall surface of one side of the first connecting block 1, and a slot 3 is sleeved on the outer surface of the insertion block 2. Moreover, a second connecting block 4 is fixedly connected to the outer surface of one side of the slot 3. A tightening bolt 5 is threadedly connected to the inside of the surfaces of one side of the first connecting block 1 and the second connecting block 4. Connecting structures 6 are arranged at both ends of the first connecting block 1 and the second connecting block 4. A protective structure 7 covers the outer surfaces of the first connecting block 1, the slot 3, and the second connecting block 4;

[0025] The connecting structure 6 includes a positioning rod 61 and a fixing rod 63. Positioning rods 61 are fixedly connected to both ends of the inner wall surface of one side of the first connecting block 1. Fixing rods 63 are fixedly connected to both ends of the inner wall surface of one side of the second connecting block 4. Moreover, the positioning rod 61 is inserted into the inside of the fixing rod 63. The connecting structure 6 further includes a positioning groove 62, and the positioning groove 62 is opened in the inside of the outer surface of one end of the positioning rod 61. Receiving grooves are opened in the inside of both ends of the surface of the second connecting block 4, and insertion rods 64 are inserted into the inside of the receiving grooves. Moreover, a positioning block 65 is fixedly connected to the outer surface of one end of the insertion rod 64. A first spring 66 is sleeved at the position of the insertion rod 64 inside the receiving groove on the outer surface. Moreover, a pull plate 67 is fixedly connected to the outer surface of the other end of the insertion rod 64. The internal dimension of the positioning groove 62 is the same as the external dimension of the positioning block 65, and the position of the positioning groove 62 corresponds to the position of the positioning block 65. Both ends of the first spring 66 respectively abut against one side surface of the receiving groove and one side surface of the positioning block 65. According to Figure 2 and Figure 3 As shown, when pulling the insertion rod 64, the positioning block 65 can be driven to be received into the inside of the receiving groove. At this time, the positioning block 65 can be disengaged from the inside of the positioning groove 62, and due to the self-elasticity of the first spring 66, the positioning block 65 can be reset automatically after moving, so as to facilitate positioning the position of the positioning rod 61 through the positioning block 65;

[0026] The protective structure 7 includes a first protective cover 71 and a second protective cover 72. The inner surfaces of the first protective cover 71 and the second protective cover 72 are attached to the outer surfaces of the first connection block 1, the slot 3, and the second connection block 4. The protective structure 7 further includes heat dissipation grooves 73. Heat dissipation grooves 73 are provided inside the upper surface of the first protective cover 71 and the lower surface of the second protective cover 72. Dust shields 74 are fixedly connected to the outer surfaces on both sides of the first protective cover 71 and the second protective cover 72. Clamping plates 75 are fixedly connected to the outer surfaces at both ends of the first protective cover 71. Moving grooves 76 are provided inside the surfaces on both sides at both ends of the second protective cover 72. A moving rod 77 is inserted into the moving groove 76. A second spring 78 is sleeved at the position of the outer surface of the moving rod 77 inside the moving groove 76. A clamping frame 79 is fixedly connected to the outer surface of one end of the moving rod 77. The dust shield 74 is semi-conical, and multiple groups of dust shields 74 are provided, and the positions of the multiple groups of dust shields 74 correspond to each other. According to Figure 4 As shown, this design enables the semi-conical dust shield 74 to be sleeved on the outer surface of the connecting wire. At this time, the semi-conical dust shield 74 can block the position of the equipment wiring port, preventing dust from accumulating inside the wiring port;

[0027] A clamping block is provided on the outer surface at the lower end of the clamping plate 75. The bottom surface of the clamping frame 79 is attached to the upper surface of the clamping block. A limiting ring is provided on the outer surface of one end of the moving rod 77, and the outer diameter of the limiting ring is the same as the inner diameter of the moving groove 76. The two ends of the second spring 78 respectively abut against one side surface inside the moving groove 76 and one side surface of the limiting ring. According to Figure 4 and Figure 5 As shown, this design enables the moving rod 77 to move inside the moving groove 76, and the limiting ring prevents the moving rod 77 from disengaging from the inside of the moving groove 76. When pulling the clamping frame 79, the bottom surface of the clamping frame 79 no longer adheres to the clamping block provided on the outer surface at the lower end of the clamping plate 75. At this time, the first protective cover 71 and the second protective cover 72 can be separated. At the same time, the self-elasticity of the second spring 78 can drive the moving rod 77 and the clamping frame 79 to reset themselves.

[0028] Working principle: When the device is in use, first insert the positioning rod 61 into the inside of the fixed rod 63. At this time, the insertion block 2 is synchronously inserted into the inside of the slot 3. Pull the pull plate 67 to move the insertion rod 64 outwards, and drive the positioning block 65 to be received into the inside of the receiving groove. Then, due to the elastic force of the first spring 66, the positioning block 65 automatically resets itself and is inserted into the positioning groove 62. Thus, the connection between the first connection block 1, the insertion block 2, the slot 3, and the second connection block 4 is completed through the connection structure 6. Then, insert the connection wire into the inside of the side surfaces of the first connection block 1 and the second connection block 4, and rotate and tighten the bolt 5 to fix the position of the connection wire. Subsequently, cover the first protective cover 71 and the second protective cover 72 on the outer surfaces of the first connection block 1, the slot 3, and the second connection block 4. The bottom surface of the engaging frame 79 fits onto the engaging block provided on the outer surface of the lower end of the engaging plate 75, thereby positioning the positions of the first protective cover 71 and the second protective cover 72. At this time, the dust-proof cover 74 is sleeved on the outer surface of the connection wire. Thus, the device is protected through the protection structure 7, and the device can be dissipated heat through the heat dissipation slots 73 to ensure the connection between the device and the outside air;

[0029] When the device needs to be disassembled and repaired, pull the engaging frame 79 to move the moving rod 77 inside the moving groove 76. At this time, the engaging frame 79 no longer engages with the engaging plate 75. At the same time, due to the elastic force of the second spring 78, the moving rod 77 and the engaging frame 79 automatically reset themselves. Thus, the first protective cover 71 and the second protective cover 72 can be removed from the outer surfaces of the first connection block 1, the slot 3, and the second connection block 4. Then, pull the pull plate 67 outwards to drive the insertion rod 64 to drive the positioning block 65 out of the inside of the positioning groove 62. At this time, the positioning rod 61 can be pulled out from the inside of the fixed rod 63, and the insertion block 2 can be disengaged from the inside of the slot 3. Thus, the disassembly of the device is completed for easy repair. The above is the entire working principle of this utility model.
