[0002] The terminal block is an electrical component used to connect circuits in electrical equipment. The terminal block can facilitate the organization of wires, avoid a large number of wires being entangled together, and make the wire layout clearer and more beautiful. The terminal block needs to be installed inside the distribution box to connect the internal electrical components of the distribution box with the external wires. The terminal block may be damaged due to excessive temperature caused by loose terminals during use. At this time, it needs to be disassembled and repaired.

[0011] Preferably, the cross-section of the top end of the insert block is a trapezoidal structure, and the cross-section of the end of the mounting seat is an L-shaped structure.

[0012] Preferably, a connecting shaft is rotatably connected to the inserting block, a stopper is fixedly connected to the connecting shaft, and a bottom end of the stopper abuts against a top end of the baffle.

[0024] As a technical optimization solution of the utility model, Figure 4 As shown, one end of the return spring 304 abuts against the slider 302 , and the other end of the return spring 304 abuts against the mounting seat 1 , so the pressing block 301 can be automatically reset under the action of the return spring 304 .

[0025] As a technical optimization solution of the utility model, Figure 4 As shown, the cross section of the slider 302 is an L-shaped structure, and the cross section of one end of the clamping block 303 is a trapezoidal structure, so it can play a guiding role when the clamping block 303 is engaged with the connecting seat 2.

[0026] As a technical optimization solution of the utility model, Figure 4 As shown, the cross section of the top of the positioning block 4 is a trapezoidal structure, and the two sides of the cross section of the connecting seat 2 are stepped structures, so the connecting seat 2 can be positioned by the positioning block 4.

[0027] As a technical optimization solution of the utility model, Figure 3 and Figure 4 As shown, four screws 6 are threadedly connected to the connection base 2, and a pressing sheet 7 is sleeved on the outside of the screws 6, so that the wires and the conductive sheet 5 can be fixed.

[0028] As a technical optimization solution of the utility model, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, two plug blocks 9 are fixedly connected to the top of the mounting base 1, and a baffle 8 is abutted against the top of the mounting base 1. The two ends of the baffle 8 are respectively engaged with the two plug blocks 9. The cross-section of the top of the plug block 9 is a trapezoidal structure, and the cross-section of the end of the mounting base 1 is an L-shaped structure.
