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

[0002] Terminal blocks are components used for electrical connections and are widely used in various electrical equipment, power distribution systems, industrial automation, communication equipment and other fields. Their main function is to securely connect wires to the electrical ports of electrical equipment.

[0003] When using terminal blocks, the two rows of control blocks at the top of the housing deform the spring contacts inside. The cable passes through the two rows of wiring slots on both sides of the housing and through the through holes on the surface of the spring contacts. Releasing the control blocks resets the spring contacts, which then move the cable to clamp and secure it, completing the connection of the cable to multiple rows of terminal blocks. When connecting multiple cables simultaneously, multiple control blocks need to be moved repeatedly before connecting the cables, resulting in numerous steps and reducing the efficiency of connecting multiple cables at the same time. This can negatively impact the effectiveness of the terminal blocks. Utility Model Content

[0004] The technical problem this invention aims to solve is that when connecting multiple cables simultaneously, it is necessary to repeatedly move multiple control blocks before connecting the cables, resulting in numerous operation steps, which affects the efficiency of connecting multiple cables at the same time, and thus leads to problems affecting the performance of the terminal blocks.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a multi-row terminal block, including a housing, a plurality of wiring grooves on both sides of the housing, a plurality of control blocks on both sides of the housing, a plurality of spring pieces on both sides of the interior of the housing, and fixing components on both sides of the housing. The housing is equipped with a moving device through the fixing components on both sides, and the moving device moves the plurality of control blocks through the moving blocks.

Several locking slots are formed on the slide rail near the locking block. The sliding block is disposed inside the slide rail. The moving block is disposed on one side of the sliding block, and the moving block is close to the control block. The locking block passes through the sliding block to engage with the locking slots formed on one side of the slide rail. The two ends of the spring are connected to the locking block and the sliding block respectively to reset the locking block.

[0007] Preferably, a limiting rod is sleeved inside the spring. One side of the limiting rod is connected to the locking block, and the other side of the limiting rod is slidably connected to the sliding block to limit the shape of the spring.

[0008] Preferably, the sliding block has arc strips on both sides, and the arc surface of the arc strips is close to the slide rail to reduce the contact area between the slide rail and the sliding block.

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

[0010] Preferably, the moving block is provided with a rubber block on the side near the control block to replace the moving block in the process of wear and tear on the control block.

[0019] 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.

[0020] Figures 1 to 5 The multi-row terminal block shown includes a housing 1, with several wiring slots 2 on both sides of the housing 1, several control blocks 3 on both sides of the housing 1, several spring contacts 4 on both sides of the interior of the housing 1, and fixing components 6 on both sides of the housing 1. A moving device 5 is mounted on the housing 1 via the fixing components 6 on both sides. The moving device 5 moves the control blocks 3 via moving blocks 53. When using the terminal block, the moving device 5 is fixed to both sides of the housing 1 via the fixing components 6. Then, the moving device 5 moves the control blocks 3 on the two rows at the top of the housing 1 simultaneously, causing the spring contacts 4 inside the housing 1 to deform. The cable passes through the wiring slots 2 on both sides of the housing 1 and through the through holes on the surface of the spring contacts 4. Then, the moving device 5 releases the control blocks 3, causing the spring contacts 4 inside the housing 1 to reset. The spring contacts 4 then move the cable to clamp and fix it, thus completing the cable connection on the multi-row terminal block.

[0021] Figures 1 to 5The movable device 5 shown includes a slide rail 51, a sliding block 52, a moving block 53, a locking block 54, and a spring 55. The slide rail 51 is mounted on one side of the housing 1 via a fixing component 6. Several locking slots are opened on the side of the slide rail 51 near the locking block 54. The sliding block 52 is located inside the slide rail 51. The moving block 53 is located on one side of the sliding block 52, and the side of the moving block 53 is close to the control block 3. The locking block 54 passes through the sliding block 52 to engage with the locking slots opened on one side of the slide rail 51. The two ends of the spring 55 are connected to the locking block 54 and the sliding block 52 respectively to reset the locking block 54.

[0022] Figures 1 to 5 As shown, when the fixed assembly 6 fixes the slide rail 51 to one side of the housing 1 for use of the moving device 5, the locking block 54 can be moved so that it moves inside the sliding block 52 and is not engaged with the slide rail 51. At this time, the spring 55 fixed to the locking block 54 and the sliding block 58 deforms. Then the sliding block 52 is moved so that it slides inside the slide rail 51. At this time, the sliding block 52 drives the moving block 53 fixed on one side to contact the control block 3, thereby driving the movement of several control blocks 3 in a row on the housing 1. Then the several control blocks 3 deform the row of spring pieces 4 inside the housing 1. Then the locking block 54 is released, and the spring 55 drives the locking block 54 to move back to its original position, so that the locking block 54 moves inside the sliding block 52 and is engaged with the slide rail. The surface slot 51 is used for locking and fixing to limit the position of the control block 3. After the cable is inserted into the wiring slot 2 of the housing 1, the locking block 54 is not locked with the slot of the slide rail 51. Then the sliding block 52 is moved to the initial position and fixed, so that the spring 4 is reset, thereby driving the control block 3 to reset. By using the moving device 5, a row of control blocks 3 on one side of the housing 1 can be moved simultaneously, so that the operator can insert multiple cables into several wiring slots 2 on one side of the housing 1 at the same time to connect the cables. This avoids the need to repeatedly move multiple control blocks 3 and then connect the cables when connecting multiple cables at the same time, which leads to many operation steps and affects the efficiency of connecting multiple cables at the same time, thereby improving the use effect of the terminal block.

[0023] Figures 1 to 5A limiting rod 56 is fitted inside the spring 55. One side of the limiting rod 56 is connected to the locking block 54, and the other side is slidably connected to the sliding block 52 to restrict the shape of the spring 55. By fitting the limiting rod 56 inside, fixing one side of the limiting rod 56 to the locking block 54, and slidably connecting the other side to the sliding block 52, the limiting rod 56 restricts the shape of the spring 55, preventing the spring 55 from bending and affecting its use. Arc strips 57 are provided on both sides of the sliding block 52. The arc surfaces of the arc strips 57 are close to the slide rail 51 to reduce the contact area between the slide rail 51 and the sliding block 52. By fixing the arc strips 57 to both sides of the sliding block 52 and having their arc surfaces in contact with the slide rail 51, the contact area between the sliding block 52 and the slide rail 51 is reduced, thus reducing the friction between them and making it easier for the sliding block 52 to slide inside the slide rail 51.

[0024] Figures 1 to 5 The movable block 53 shown has several anti-slip blocks 58 on one side to increase the friction on that side. By fixing several anti-slip blocks 58 to one side of the movable block 53, the friction on that side is increased, allowing the operator to firmly hold one side of the movable block 53 for movement, thereby improving the usability of the movable block 53. A rubber block 59 is provided on the side of the movable block 53 near the control block 3 to replace the movable block 53 in contact with the control block 3. By fixing the rubber block 59 to one side of the movable block 53, the rubber block 59 replaces the movable block 53 in contact and wear with the control block 3, thereby extending the service life of the movable block 53.

[0025] Figures 1 to 5 The fixing component 6 shown includes a square tube 61, a bolt 62, and a mounting bracket 63. The square tube 61 is disposed on one side of the outer casing 1, and the bolt 62 is inserted into one side of the square tube 61 and threadedly fixed to the mounting bracket 63. One side of the mounting bracket 63 is connected to the slide rail 51. When using the fixing component 6, the mounting bracket 63 is moved so that one side of the mounting bracket 63 is inserted into the square tube 61 fixed on one side of the outer casing 1. Then, the bolt 62 is rotated so that the bolt 62 passes through the square tube 61 and is threadedly fixed to the mounting bracket 63. Then, the slide rail 51 fixed on one side of the mounting bracket 63 is fixed to one side of the outer casing 1. By using the fixing component 6, the slide rail 51 can be fixed to one side of the outer casing 1, which facilitates the operator's subsequent use of the mobile device 5, thereby improving the usability of the mobile device 5.

[0026] Figures 1 to 5 The placement rack 63 shown has a reinforcing plate 64 on one side, and one side of the reinforcing plate 64 is connected to the slide rail 51 to improve the connection strength between the placement rack 63 and the reinforcing plate 64. By fixing the two ends of the reinforcing plate 64 to the slide rail 51 and the placement rack 63, the connection strength between the placement rack 63 and the slide rail 51 is improved, and deformation under stress at the connection point is prevented.

[0027] Working principle: When using the terminal blocks, the moving device 5 is fixed to both sides of the housing 1 by the fixing component 6. Then, the moving device 5 moves several control blocks 3 on the two rows at the top of the housing 1 simultaneously, causing the spring pieces 4 inside the housing 1 to deform. The cable passes through the two rows of wiring slots 2 on both sides of the housing 1 and through the through holes on the surface of the spring pieces 4. Then, the moving device 5 releases several control blocks 3, causing several spring pieces 4 inside the housing 1 to reset. Then, the spring pieces 4 drive the cable to move, clamping and fixing the cable, and then completing the wiring of the cable on the multi-row terminal blocks. When the fixed assembly 6 fixes the slide rail 51 to one side of the housing 1 for use of the moving device 5, the locking block 54 can be moved so that it moves inside the sliding block 52 and is not engaged with the slide rail 51. At this time, the spring 55 fixed to the locking block 54 and the sliding block 52 deforms. Then the sliding block 52 is moved so that it slides inside the slide rail 51. At this time, the sliding block 52 drives the moving block 53 fixed on one side to contact the control block 3, thereby driving the movement of several control blocks 3 in a row on the housing 1. Then the several control blocks 3 deform the row of spring pieces 4 inside the housing 1. Then the locking block 54 is released, and the spring 55 drives the locking block 54 to move back to its original position, so that the locking block 54 moves inside the sliding block 52 and is engaged with the slide rail 51. 1. The surface slot is used for locking and fixing to limit the position of the control block 3. After the cable is inserted into the wiring slot 2 of the housing 1, the locking block 54 is not locked with the slot of the slide rail 51. Then the sliding block 52 is moved to the initial position and fixed, so that the spring 4 is reset, thereby driving the control block 3 to reset. By using the moving device 5, a row of control blocks 3 on one side of the housing 1 can be moved at the same time, so that the operator can insert multiple cables into several wiring slots 2 on one side of the housing 1 at the same time to connect the cables. This avoids the need to repeatedly move multiple control blocks 3 and then connect the cables when connecting multiple cables at the same time, which leads to many operation steps and affects the efficiency of connecting multiple cables at the same time, thereby improving the use effect of the terminal block.

[0028] When using the fixing component 6, move the placement bracket 63 so that one side of the placement bracket 63 is inserted into the square tube 61 fixed on one side of the outer casing 1. Then rotate the bolt 62 so that the bolt 62 passes through the square tube 61 and is threadedly fixed to the placement bracket 63. Then the slide rail 51 fixed on one side of the placement bracket 63 is fixed to one side of the outer casing 1. By using the fixing component 6, the slide rail 51 can be fixed to one side of the outer casing 1, which makes it convenient for the operator to use the moving device 5 later, thereby improving the use effect of the moving device 5.
