Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, specifically a knife-type terminal block. Background Technology

[0002] Terminal blocks are used to facilitate the connection of wires. They are actually a metal plate encased in insulating plastic, with holes at both ends for inserting wires and screws for tightening or loosening. For example, if two wires need to be connected sometimes and disconnected at other times, they can be connected with terminals and disconnected at any time without having to solder or twist them together, which is very convenient and quick.

[0003] However, existing terminal blocks often use bolts to tighten wires when connecting them. This method requires repeatedly turning the bolts to secure the wires. When disconnecting, the bolts also need to be turned in the opposite direction to loosen the wires. The whole process involves many steps and is time-consuming. Especially in scenarios where frequent wiring or disconnection is required, this method increases time costs, seriously affects work efficiency, and is highly dependent on the tightening force of the bolts. If the tightening force is insufficient, the bolts are prone to loosening after long-term use or when subjected to vibration, external forces, etc., resulting in poor wire contact. If the tightening force is too strong, the wires may be squeezed and bent, which will affect the normal operation of the circuit and may even cause safety hazards and affect the use of the device.

[0004] Therefore, we propose a knife-type terminal block to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a knife-type terminal block to solve the problems mentioned in the background art, such as the cumbersome installation of wires and terminals, their easy loosening, or their easy squeezing and bending, which affect the normal operation of the circuit.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a knife-type terminal block, comprising a terminal block body, wherein multiple insertion holes are provided on the surface of the terminal block body, and wires are inserted into the multiple insertion holes. A spring is fixed inside the multiple insertion holes, and a clamping ring is fixed on the top surface of the spring. An installation assembly is installed on the multiple insertion holes, and the installation assembly includes a rotating rod fixed on the terminal block body. Multiple knife gates are rotatably installed on the rotating rod. Multiple sliding rods are slidably connected inside the terminal block body, and a clamping ring is fixed on the bottom surface of the sliding rod. The inner walls of both the clamping ring and the clamping ring are in contact with the outer wall of the wire.

[0007] Preferably, the knife gate has a through hole for rotatably mounting with the rotating rod, a connecting block is fixed to the side wall of the knife gate, a connecting rod is hinged to one end of the connecting block, a sliding rod is hinged to the other end of the connecting rod, a T-shaped column is fixed to the bottom surface of the sliding rod, and the T-shaped column is fixedly connected to the sliding rod.

[0008] Preferably, a second spring is sleeved on the outer ring of the slide rod, one end of the second spring is fixedly connected to the T-shaped post, and the other end of the second spring is fixedly connected to the terminal block body.

[0009] Preferably, multiple mounting boxes are fixed on the terminal block body, and each of the multiple knife gates has a slot. The slot is adapted to the shape of the mounting box. The mounting box is hollow, and annular grooves are formed on both sides of the mounting box. The sliding rod is slidably connected to the annular groove.

[0010] Preferably, the surface of the mounting box is provided with a through groove, and a movable rod is slidably connected in the through groove, the movable rod being fixedly connected to the sliding rod.

[0011] Preferably, a locking rod is movably installed on the outer ring of the movable rod, and multiple locking slots are opened on the surface of the mounting box. The multiple locking slots are arranged linearly, the locking slots are connected to the through slots, and the locking rod is engaged with the locking slots.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. Compared to traditional terminal blocks that use bolt tightening, this knife-type terminal block uses a mechanical linkage structure to achieve rapid clamping and release of wires. When connecting, simply insert the wire and rotate the knife gate, and fix the position by the cooperation of the locking rod and the locking slot. When disconnecting, simply remove the locking rod, and the spring force of the second spring will automatically complete the release and opening of the knife gate. There is no need to repeatedly tighten the bolts, which greatly simplifies the wiring process, reduces operation steps and time costs, and improves work efficiency.

[0013] 2. This terminal block provides a stable and controllable clamping force according to the wire specifications and actual connection requirements. Compared with the high dependence of traditional bolt connections on tightening force, it effectively avoids a series of problems caused by improper force control. It avoids the risk of poor contact caused by the wire loosening under long-term use, vibration or external force when the bolt is not tightened enough, ensuring the firmness and conductivity stability of the wire connection. It also prevents damage to the wire caused by excessive compression and bending when the bolt is tightened too much. The structural design achieves protective clamping of the wire, ensuring that the circuit is always in a safe and stable operating state, further improving the reliability and safety of wiring operations.

[0014] 3. Through the elastic action of springs one and two, and the cooperation structure of clamping ring one and clamping ring two, this terminal block can adapt to wires of different diameters. Operators can flexibly adjust the clamping force according to the actual wire thickness, without the need to replace the terminal block with a special one for wires of different diameters, which enhances the versatility and practicality of the product and reduces the user's operating costs.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: This embodiment aims to address a series of operational and performance defects inherent in traditional bolt-tightening terminal blocks during practical applications. Please refer to [link / reference]. Figure 1 - Figure 5A knife-type terminal block includes a terminal block body 1. The surface of the terminal block body 1 has multiple insertion holes 2, into which wires 3 are inserted. The multiple insertion holes 2 provide independent channels for the insertion of the wires 3, ensuring the independence of different wires 3 during connection and avoiding mutual interference. A spring 4 is fixed inside each of the multiple insertion holes 2, and a clamping ring 5 is fixed to the top surface of the spring 4. This clamping ring 5 provides initial clamping and positioning of the wires 3 during initial insertion, preventing the wires 3 from moving freely within the insertion holes 2. The terminal block 1 is equipped with a mounting assembly 6 on multiple insertion holes 2. The mounting assembly 6 includes a rotating rod 61 fixed on the terminal block body 1. Multiple knife gates 62 are rotatably mounted on the rotating rod 61. The rotating rod 61 provides a stable support point for the rotation of the knife gates 62, so that the knife gates 62 can rotate flexibly around the rotating rod 61 to realize the opening and closing operation. Multiple sliding rods 69 are slidably connected inside the terminal block body 1. A second clamping ring 610 is fixed on the bottom surface of the sliding rod 69. The inner walls of the first clamping ring 5 and the second clamping ring 610 are both in contact with the outer wall of the wire 3.

[0019] The knife gate 62 has a through hole 63 that is rotatably installed with the rotating rod 61. A connecting block 65 is fixed to the side wall of the knife gate 62. A connecting rod 66 is hinged to one end of the connecting block 65. A sliding rod 67 is hinged to the other end of the connecting rod 66. A T-shaped column 68 is fixed to the bottom surface of the sliding rod 67. The T-shaped column 68 is fixedly connected to the sliding rod 69.

[0020] A second spring 691 is sleeved on the outer ring of the slide rod 69. One end of the second spring 691 is fixedly connected to the T-shaped post 68, and the other end of the second spring 691 is fixedly connected to the terminal body 1. Multiple mounting boxes 611 are fixed on the terminal body 1. Each of the multiple knife gates 62 has a slot 64. The slot 64 is adapted to the shape of the mounting box 611. When the knife gate 62 is closed, the mounting box 611 can be embedded in the slot 64, making the structure more compact. The mounting box 611 is hollow, providing space for the installation and movement of internal components. Annular grooves 612 are opened on both sides of the mounting box 611, and the slide rod 67 is slidably connected to the annular grooves 612.

[0021] The surface of the mounting box 611 has a through groove 615, and a movable rod 613 is slidably connected in the through groove 615. The movable rod 613 is fixedly connected to the sliding rod 67. A locking rod 614 is movably installed on the outer ring of the movable rod 613. The surface of the mounting box 611 has multiple locking slots 616, which are arranged linearly. The locking slots 616 are connected to the through groove 615, and the locking rod 614 is engaged with the locking slots 616.

[0022] In this embodiment: After the wires 3 to be connected are inserted into the corresponding plug holes 2, the clamping ring 5 inside the plug hole 2 is tightly attached to the outer wall of the wire 3 under the elastic force of the spring 4, and quickly completes the initial clamping and positioning of the wire 3. This design can effectively prevent the wires 3 from shaking significantly inside the plug hole 2, ensuring that the wires 3 are always in a precise connection position, laying a stable foundation for subsequent operations.

[0023] During the connection operation, the operator first manually pulls the locking lever 614 to disengage it from the locking slot 616. Then, the locking lever 614 is rotated around the outer ring of the movable rod 613 until it is completely offset from the locking slot 616. This pre-processing operation can prevent the locking lever 614 from interfering with the subsequent sliding of the movable rod 613, ensuring the smoothness of mechanical transmission. After adjusting the locking lever 614, the knife gate 62 is rotated around the rotating rod 61. Since the knife gate 62 forms a hinged structure with the sliding rod 67 through the connecting block 65 and the connecting rod 66, its rotation will drive the connecting block 65 and the connecting rod 66 to move in sequence, ultimately pushing the sliding rod 67 to slide smoothly down along the annular grooves 612 on both sides of the mounting box 611. During the downward movement of the sliding rod 67, the sliding rod 69 is moved downward synchronously through the T-shaped column 68, causing the clamping ring 610 on the bottom surface of the sliding rod 69 to move closer to the clamping ring 5. At this time, the spring 691 is gradually compressed and accumulates elastic force.

[0024] As the knife gate 62 continues to rotate, clamping ring 610 and clamping ring 5 eventually form a tight clamp on the wire 3. During the downward movement of sliding rod 67, movable rod 613 will slide synchronously with it in through groove 615. When the wire 3 is clamped to the required degree, the locking rod 614 on the outer ring of movable rod 613 is rotated so that it is on the same plane as the locking groove 616. Then the locking rod 614 is pushed into the locking groove 616 to complete the locking, thereby fixing the position of sliding rod 67 and keeping the clamping state of clamping ring 610 on wire 3 stable, realizing a fast and reliable connection between terminal block and wire 3.

[0025] When it is necessary to disconnect the wire 3, the operator only needs to remove the clamp 614 from the slot 616 and then rotate the clamp 614 so that it is perpendicular to the slot 616, thereby releasing the fixed constraint on the sliding rod 67. At this time, the compressed spring 691 quickly recovers its deformation, releasing the upward elastic force to push the T-shaped column 68 upward, which in turn drives the sliding rod 67, the sliding rod 69, and the clamping ring 610 to rise synchronously, increasing the distance between the clamping ring 610 and the clamping ring 5, thus releasing the clamp on the wire 3. At the same time, the sliding rod 67 drives the knife gate 62 to rotate upward around the rotating rod 61 through the connecting rod 66 and the connecting block 65, so that the knife gate 62 opens automatically, and the operator can easily take the wire 3 out of the insertion hole 2.

[0026] Compared to the existing technology that uses bolts to tighten the terminals of the wire 3, this operation method, which achieves rapid clamping and release through mechanical linkage, greatly simplifies the wiring process and improves the ease of operation.
