Description

Technical Field

[0001] This utility model relates to the field of terminal blocks, and in particular to a plug-in clamping terminal block. Background Technology

[0002] Terminal blocks are components used to connect wires and electrical equipment. They are commonly used in power, electronics, communication, and automation systems to help ensure stable circuit connections and facilitate later maintenance and replacement.

[0003] When using terminal blocks, moving the control block on the housing causes the internal spring contacts to deform. The cable is then inserted into the housing's connector slot. Releasing the control block releases the spring contacts, securing the cable in the connector slot. When wiring multiple cables, multiple control blocks need to be moved to deform the internal spring contacts, resulting in numerous steps, reduced wiring efficiency, and consequently, problems affecting the terminal block's performance. Utility Model Content

[0004] The technical problem this invention aims to solve is that when multiple cables need to be wired, multiple control blocks need to be moved multiple times to deform multiple springs inside the housing, resulting in numerous operation steps, affecting the efficiency of wiring, and thus affecting the performance of the wiring terminals.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a plug-in clamping terminal block, including a housing, a plurality of control blocks are provided on one side of the housing, a plurality of spring contacts are provided inside the housing, a plurality of plug-in slots are opened on the side of the housing near the control blocks, and an auxiliary device is provided on the side of the housing near the control blocks. The auxiliary device controls the plurality of control blocks simultaneously through an auxiliary plate.

[0006] Preferably, the auxiliary device includes a placement block, a sliding block, an auxiliary plate, and a spring. The placement block is disposed on the side of the housing near the control block. The sliding block is disposed inside the placement block to drive the auxiliary plate to move. The spring is disposed inside the placement block, and its two ends are respectively connected to the placement block and the sliding block to reset the auxiliary plate.

[0007] Preferably, a limiting component is provided on one side of the auxiliary plate, and the limiting component restricts the position of the auxiliary plate.

[0008] Preferably, the limiting component includes a sliding hole on one side of the auxiliary plate, a limiting block, and a limiting groove on one side of the placement block. The limiting block slides inside the sliding hole on one side of the auxiliary plate, and the size of the limiting block is adapted to the size of the limiting groove on one side of the placement block.

[0009] Preferably, the limiting block is provided with a plurality of anti-slip blocks on one side to increase the friction on one side of the limiting block.

[0010] Preferably, the auxiliary plate has a curved surface on the side near the control block to better fit with the control block.

[0011] Preferably, the auxiliary plate is provided with reinforcing plates on both sides to enhance the strength of the auxiliary plate on the side closer to the control block.

[0012] Preferably, the sliding block has arc blocks on both sides to reduce the contact area between the sliding block and the placement block.

[0013] In summary, the beneficial effects of this utility model are as follows: By using an auxiliary device, multiple control blocks can be moved synchronously, causing the springs inside the housing to be compressed and deformed simultaneously. This reduces the number of steps required when wiring multiple cables, allowing operators to quickly insert multiple cables into the sockets of the housing for wiring, thereby improving wiring efficiency and ultimately enhancing the performance of the terminal blocks.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Figures 1 to 6 The diagram shows a plug-in clamping terminal block, comprising a housing 1, with several control blocks 2 on one side of the housing 1, several spring contacts 3 inside the housing 1, several plug slots 4 on the side of the housing 1 near the control blocks 2, and an auxiliary device 5 on the side of the housing 1 near the control blocks 2. The auxiliary device 5 controls the control blocks 2 simultaneously via an auxiliary plate 53. When connecting multiple cables using the terminal block, the auxiliary device 5 moves all the control blocks 2 on the housing 1 simultaneously, causing the spring contacts 3 inside the housing 1 to be compressed and deformed. Then, multiple cables are inserted into the plug slots 4 of the housing 1. The auxiliary device 5 then releases the control blocks 2, and the spring contacts 3 return to their original positions, clamping the cables inside the plug slots 4 of the housing 1 to complete the cable connection.

[0020] Figures 1 to 6 The auxiliary device 5 shown includes a placement block 51, a sliding block 52, an auxiliary plate 53, and a spring 54. The placement block 51 is located on the side of the outer casing 1 near the control block 2. The sliding block 52 is located inside the placement block 51 to drive the auxiliary plate 53 to move. The spring 54 is located inside the placement block 51, and its two ends are connected to the placement block 51 and the sliding block 52 respectively to reset the auxiliary plate 53.

[0021] Figures 1 to 6As shown, when multiple control blocks 2 are moved simultaneously using the auxiliary device 5, the auxiliary plate 53 can be moved, causing the sliding block 52 fixed on one side to slide inside the placement block 51. At this time, the spring 54 fixed to the sliding block 52 and the placement block 51 is compressed and deformed. Then, both ends of the auxiliary plate 53 contact and press all control blocks 2, causing all control blocks 2 to move inside the housing 1, thereby compressing and deforming the spring 3. Then, multiple cables are inserted into different plug slots 4. Then, the auxiliary block is released, causing the spring 54 to drive the sliding block 52 and the auxiliary plate 53 to reset. Then, the control blocks 2 no longer compress the spring 3, allowing the spring 3 to reset and secure the cables. By using the auxiliary device 5, multiple control blocks 2 can be moved synchronously, and the spring 3 inside the housing 1 can be compressed and deformed simultaneously. This reduces the number of steps when wiring multiple cables, allowing operators to quickly insert multiple cables into the plug slots 4 of the housing 1 for wiring, thereby improving wiring efficiency and the effectiveness of the terminal blocks.

[0022] Figures 1 to 6 The auxiliary plate 53 shown is provided with a limiting component 55 on one side, which restricts the position of the auxiliary plate 53. The limiting component 55 includes a sliding hole 551, a limiting block 552, and a limiting groove 553 on one side of the placement block 51. The limiting block 552 slides inside the sliding hole 551 on one side of the auxiliary plate 53, and the size of the limiting block 552 is adapted to the size of the limiting groove 553 on the side of the placement block 51. When the auxiliary plate 53 approaches the placement block 51, the limiting block 552, which is slidably connected inside the sliding hole 551 on one side of the auxiliary plate 53, reaches the limiting groove 553 on one side of the placement block 51. Then, the limiting block 552 inside the sliding hole 551 on one side of the auxiliary plate 53 is moved so that one end of the limiting block 552 is engaged with the limiting groove 553 of the placement block 51, thus completing the limiting of the auxiliary plate 53. This allows the operator to insert the cable into the plug slot 4 without applying force to fix the auxiliary plate 53. After multiple cables are inserted into different wiring slots, the limiting block 552 is moved so that it is not engaged with the limiting groove 553 on the surface of the placement block 51. Then, the spring 54 returns to its original position, causing the auxiliary plate 53 to quickly return to its original position.

[0023] Figures 1 to 6 The limiting block 552 shown has several anti-slip blocks 554 on one side to increase the friction on one side of the limiting block 552. By fixing several anti-slip blocks 554 to one side of the limiting block 552, the friction on the surface of the limiting block 552 is increased, making it easier for the limiting block 552 to move.

[0024] Figures 1 to 6The auxiliary plate 53 shown is curved on the side near the control block 2 to better fit with the control block 2. By making the side of the auxiliary plate 53 near the control block 2 curved, the auxiliary plate 53 fits the control block 2 better, and the auxiliary plate 53 can more stably control the movement of the control block 2, thereby improving the performance of the auxiliary plate 53.

[0025] Figures 1 to 6 The auxiliary plate 53 shown has reinforcing plates 56 on both sides to enhance the strength of the auxiliary plate 53 near the control block 2. By fixing the reinforcing plates 56 to the side of the auxiliary plate 53 near the control block 2, the strength of this side is increased, preventing deformation of the auxiliary plate 53 near the control block 2 and thus improving its performance. The sliding block 52 has arc-shaped blocks 57 on both sides to reduce the contact area between the sliding block 52 and the placement block 51. By fixing the arc-shaped blocks 57 to both sides of the sliding block 52, and with the arc surfaces of the arc-shaped blocks 57 close to the placement block 51, the contact area between the sliding block 52 and the placement block 51 is reduced, thus reducing friction and making it easier for the sliding block 52 to slide inside the placement block 51.

[0026] Working principle: When connecting multiple cables using terminal blocks, the auxiliary device 5 moves all the control blocks 2 on the outer shell 1 at the same time, causing the spring pieces 3 inside the outer shell 1 to be squeezed and deformed. Then, multiple cables are inserted into several plug slots 4 of the outer shell 1. Then, the auxiliary device 5 releases the control blocks 2, and the spring pieces 3 reset to lock the cables inside the plug slots 4 of the outer shell 1, thus completing the cable connection. When using the auxiliary device 5 to move multiple control blocks 2 simultaneously, the auxiliary plate 53 can be moved, causing the auxiliary plate 53 to drive the sliding block 52 fixed on one side to slide inside the placement block 51. At this time, the spring 54 fixed to the sliding block 52 and the placement block 51 is compressed and deformed. Then, the two ends of the auxiliary plate 53 contact and press all the control blocks 2, causing all the control blocks 2 to move inside the housing 1, thereby compressing and deforming the spring 3. Then, multiple cables are inserted into different plug slots 4 respectively. Then, the auxiliary block is released, causing the spring 54 to drive the sliding block 52 and the auxiliary plate 53 to reset. Then, the control blocks 2 no longer compress the spring 3, allowing the spring 3 to reset and secure the cables. By using the auxiliary device 5, multiple control blocks 2 can be moved synchronously, and the spring 3 inside the housing 1 can be compressed and deformed simultaneously. This reduces the number of steps when wiring multiple cables, allowing operators to insert multiple cables into the plug slots 4 of the housing 1 more quickly for wiring, thereby improving wiring efficiency and the performance of the terminal blocks.
