Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and more particularly to a terminal block. Background Technology

[0002] Terminal blocks, as a key circuit connector, are widely used in daily life and industrial production. They are mainly used to achieve a stable connection between wires and plugs. They are an indispensable basic component in the circuit systems of various electrical equipment, electronic instruments, and household appliances. Their performance directly affects the circuit's conduction stability, electrical safety, and the overall operational reliability of the equipment.

[0003] In practical applications, terminal blocks usually need to be mated with matching male terminals to form a complete conductive path. However, the terminal blocks commonly available on the market generally have a problem of loose connection when connected with male terminals. Specifically, when affected by external factors such as slight vibration and pulling, the connection between the two is prone to loosening or even falling off.

[0004] Such loose connections can directly lead to poor circuit contact, causing problems such as increased contact resistance and localized overheating. This can not only affect the normal operation of the equipment and reduce circuit transmission efficiency, but in severe cases, it may also cause short circuits, fires and other safety hazards due to continuous overheating, threatening the life and property safety of users.

[0007] By adopting the above technical solution, when the knob parallel to the through groove is inserted into the through groove, the knob can be rotated to a state perpendicular to the through groove, which can stably fix the male terminal to the terminal body.

[0019] By adopting the above technical solution and setting the limiting piece, a good limiting and stabilizing effect can be achieved.

[0020] Compared with the prior art, the advantages and positive effects of this application are as follows: 1. In this application, when the knob parallel to the through groove is inserted into the through groove, the knob can be rotated to a state perpendicular to the through groove, which can stably fix the male terminal to the terminal body. Through the setting of the abutment component, the male terminal and the bottom of the knob are tightly abutted. This structural design greatly improves the stability of the connection between the two.

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] Reference Figure 1-5A terminal block includes a male connector 1, a terminal block body 2 adapted to the outer side of the male connector 1, a mounting groove 13 inside the terminal block body 2, a rotating shaft 9 rotatably connected to one end of the mounting groove 13, an elastic member 8 fixedly connected to the outer side of the rotating shaft 9, and two knobs 12 rotatably connected to the top of the elastic member 8 away from the rotating shaft 9. The male connector 1 has a through groove 7 adapted to the knobs 12 inside, the two knobs 12 are arranged parallel to each other, and the male connector 1 is fixed above the terminal block body 2 by the knobs 12 and the through groove 7. The male connector 1 abuts against the bottom end of the knobs 12. When the knobs 12 parallel to the through groove 7 are in contact with the bottom end of the knobs 12, the male connector 1 is fixed above the terminal block body 2. After inserting the through slot 7, the knob 12 can be rotated to a position perpendicular to the through slot 7, which can stably fix the male terminal 1 to the terminal body 2. Through the setting of the abutment component, the male terminal 1 and the bottom end of the knob 12 are tightly in contact. This structural design greatly improves the stability of the connection between the two. Even if affected by external vibration, pulling and other factors, it is not easy to loosen or fall off, thereby reducing circuit failures caused by connection problems. Moreover, by turning the knob 12, the male terminal 1 and the terminal body 2 can be disassembled without the need for complicated tools, which greatly simplifies the disassembly steps and provides convenience for later inspection and maintenance.

[0026] Specifically, the terminal block body 2 has an internal abutment assembly, which includes a torsion spring 10 sleeved on the outer periphery of the rotating shaft 9. Fixing blocks a11 are fixedly connected to both sides of the inner wall of the mounting groove 13, and fixing blocks b15 are fixedly connected to both sides of the elastic element 8. The torsion spring 10 applies a continuous force to the elastic element 8 through the fixing blocks a11 and b15, ensuring tight contact between the male terminal 1 and the bottom end of the knob 12. This ensures good circuit contact, reduces the risk of short circuits, fires, and other safety hazards caused by poor contact, and protects the user's life and property. One end of the torsion spring 10 is connected to the fixing block... a11 is connected to the other end of the torsion spring 10 and the other end of the fixing block b15. Clamping pieces a5 and b6 are fixedly connected to the opposite sides of the male terminal 1 and the terminal body 2. Clamping pieces a5 and b6 are arranged adjacent to each other. The male terminal 1 has a wire b14 inside. By pressing the two clamping pieces a5 and two clamping pieces b6, the wire b14 can be installed on the male terminal 1. Similarly, it is easy to install the wire a4 on the terminal body 2. The terminal body 2 has a wire a4 inside. The wire a4 is pressed onto the terminal body 2 by the clamping pieces a5 and b6.

[0027] Specifically, wire b14 is also pressed onto male terminal 1 by clamping pieces a5 and b6. Male terminal 1 and terminal body 2 are made of copper alloy as base material. Copper alloy itself has excellent conductivity, and tin plating further improves its oxidation resistance and corrosion resistance. The surface is tin-plated. Limiting pieces 3 are fixedly connected to both ends of the top of terminal body 2. The setting of limiting pieces 3 can play a good limiting and stabilizing role, further enhancing the reliability of the connection. The limiting pieces 3 all abut against the outer wall of male terminal 1.

[0028] Working principle: First, place one end of wire b14 on the male terminal 1, and use a tool to press the clamping pieces a5 and b6 to fix wire b14 on the male terminal 1. Wire a4 is fixed in the same way. To prevent loosening later, wire a4 and wire b14 can be soldered together with a soldering iron. Then, the male terminal 1 can be inserted into the terminal body 2. At this time, the operator can turn the two knobs 12 parallel to the through groove 7, and insert the knobs 12 into the through groove 7. Rotating the knob 12 to a position perpendicular to the through slot 7 allows the male terminal 1 to be stably fixed to the terminal body 2. The torsion spring 10 applies a continuous force to the elastic element 8 through the fixing block a11 and fixing block b15, ensuring that the male terminal 1 and the bottom of the knob 12 are in close contact, thus ensuring good circuit contact. This structural design greatly improves the stability of the connection between the two. Even if affected by external vibration, pulling or other factors, it is not easy to loosen or fall off, thereby reducing circuit failures caused by connection problems.
