[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] The terminal block of a drawer-type circuit breaker is connected to the contacts of the circuit breaker body and the wires or busbars of the external circuit to form a complete electrical circuit. When the circuit breaker is closed, the current flows from the incoming terminal to the outgoing terminal through the terminal block, providing power to the load; when the circuit breaker is opened, the current path is cut off, realizing the control and protection of the circuit.

[0018] In this design, the opposite side of adjacent terminal blocks is designed to be recessed outward to increase the phase spacing between two adjacent terminal blocks.

[0019] Specifically, in one embodiment, such as Figures 1-3 As shown, this embodiment of a drawer-type circuit breaker terminal block structure with increased phase spacing includes, Circuit breaker body 1; Terminal block 2 is embedded in the terminal of the circuit breaker. The terminal blocks 2 are symmetrically distributed in pairs, and the opposite side of adjacent terminal blocks 2 is set with an outward concave structure. External connector 3 is detachably fixed to connector 2; Connecting bolt 4 is used to fix the external connector 3 onto the terminal block 2.

[0020] In this embodiment, the terminal blocks are symmetrically distributed, and the adjacent terminal blocks have an outward concave structure, which can increase the phase spacing between adjacent terminal blocks, giving the operator more operating space for wiring work, thereby improving the convenience of wiring work, and also facilitating inspection, maintenance and other work.

[0021] As one implementation method, such as Figures 2-5 As shown, the terminal block 2 has multiple wiring positioning holes 21, which allows the staff to select the appropriate specific wiring location according to the actual wiring needs, increasing the wiring flexibility of the terminal block.

[0022] As one implementation method, such as Figures 3-5As shown, each wiring positioning hole 21 on the terminal block 2 is provided with a wiring positioning groove 22 around it. The outer terminal block 3 is rotated and adjusted in the wiring positioning groove 22 and then fixed by the connecting bolt 4. The wiring positioning groove allows the outer terminal block to be rotated and adjusted based on the wiring positioning hole, making the wiring method of the outer terminal block more flexible. For example, the spacing between outer terminal blocks in different positions can be further increased by rotating and tilting at opposite angles, thereby improving safety.

[0023] As one implementation method, such as Figures 3-5 As shown, through holes 5 are provided on the circuit breaker body 1 at positions corresponding to the wiring positioning holes 21. Connecting bolts 4 extend through the through holes 5 to the outside of the circuit breaker body 1, and are rotatably connected to the through holes 5. An adjusting seat 6 is fixedly connected to the end of the connecting bolt 4 facing the outside of the circuit breaker body 1, and a pressure handle 7 is threaded onto the end of the connecting bolt 4 facing the outer connector 3. The connecting bolt 4 passes through the outer connector 3, and the pressure handle 7 moves relative to the rotation of the connecting bolt 4, pressing the outer connector 3 into the wiring positioning slot 22. In this embodiment, the connecting bolt... The plug and the handle adopt a separate detachable connection method. In the connection with the external connector, first unscrew the handle to remove it, insert the external connector with the connection hole into the plug, and then screw the handle and the plug together. Finally, the plug can be screwed on the outside of the circuit breaker body through the adjusting seat. Due to the threaded connection between the handle and the plug, the handle will move relative to the plug when controlled, so that the handle can press against the external connector and fix it in the wiring positioning groove.

[0024] As one implementation method, such as Figures 3-5 As shown, threaded holes are provided on the circuit breaker body 1 at positions corresponding to the wiring positioning holes 21. The connecting bolt 4 extends to the outside of the circuit breaker body 1 through the threaded holes, and the outer wall of the connecting bolt 4 engages with the internal thread of the threaded hole. An adjusting seat 6 is fixedly connected to the end of the connecting bolt 4 facing the outside of the circuit breaker body 1, and a pressure handle 7 is fixedly connected to the end of the connecting bolt 4 facing the outer connection bar 3. The outer connection bar 3 is located on one side of the connecting bolt 4, and the pressure handle 7 moves synchronously with the rotation of the connecting bolt 4 to press the outer connection bar 3 into the wiring positioning slot 22. In this embodiment, the connecting bolt and the pressure handle are fixedly connected. The connecting bolt can be engaged with the circuit breaker body based on the threaded hole. When the connecting bolt is screwed, it will move based on the threaded hole, and the pressure handle will also move synchronously with the connecting bolt. Therefore, in the connection step with the external connector, the external connector without the connecting hole is first placed on one side of the connecting bolt. When the connecting bolt is screwed out to the outside of the circuit breaker, the pressure handle will press against the external connector and fix it in the wiring positioning slot.

[0025] The two connection methods for external connectors described above, namely the connection of the connecting bolt and the pressure handle, are mainly used to cope with different external connector structures. For example, in circuit connection requirements with larger current, the external connector usually uses rigid copper busbars, while in circuit connection requirements with smaller current, the external connector usually uses flexible copper wires. In this technical solution, external connectors with connection holes are suitable for rigid copper busbars, while external connectors without connection holes are suitable for flexible copper wires. Here, the connection hole can refer to a copper lug.

[0026] As one implementation method, such as Figures 3-5 As shown, a connecting rod 8 is rotatably connected to one side wall of the circuit breaker body 1. The connecting rod 8 extends to the handle on the outer wall of the drawer cabinet and is connected by transmission. The connecting rod 8 is used to control the opening and closing of the circuit breaker body 1, which facilitates the operation and management of the circuit breaker body by the staff.

[0027] As one implementation method, such as Figures 3-5 As shown, a U-shaped bracket 9 is also fixedly installed on the side wall of the circuit breaker body 1, and the connecting rod 8 passes through the U-shaped bracket 9 and is rotatably connected; the bracket can provide auxiliary support for the connecting rod.

[0028] As one implementation method, such as Figures 3-5 As shown, both terminal block 2 and external terminal block 3 are made of copper or aluminum to ensure circuit continuity.
