[0014] 1. This utility model excels in ease of wiring. Its ingenious structure, consisting of a fixed conductive clip and a movable conductive clip within the socket, is formed by an elastic body, a guide rod, and a connecting rod.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] refer to Figure 1-5 As shown, an environmentally friendly, flame-retardant, highly reliable, and durable terminal block includes an insulating shell 1, a copper conductive sheet 7, and two copper blocks 6. Cover plates 2 are firmly fixed on both sides of the insulating shell 1 to provide protection for the internal components. The copper conductive sheet 7 and the two copper blocks 6 are precisely fixed inside the insulating shell 1, and the two copper blocks 6 are symmetrically distributed. The two ends of the copper conductive sheet 7 are respectively and firmly fixed to the two copper blocks 6. Two sockets 3 are provided on the insulating shell 1, which are located directly above the two copper blocks 6.

[0024] refer to Figure 3 A fixed conductive clip 4 and a movable conductive clip 5 are installed in the socket 3. The lower ends of both are connected to the copper block 6. The fixed conductive clip 4 and the copper block 6 are fixedly connected by a conductive post 15 to ensure smooth current conduction. A flexible flat cable 8 is fixedly connected between the movable conductive clip 5 and the copper block 6 to meet specific electrical connection requirements. The back of the movable conductive clip 5 is detachably connected to two guide rods 10 in a specific way. Specifically, the back of the movable conductive clip 5 is fixed with two parallel cylinders 9. The heads of the two guide rods 10 are respectively connected to the two cylinders 9 by a threaded connection. The guide rods 10 can slide in a closed manner inside the insulating shell 1. The ends of the two guide rods 10 connected to the back of the movable conductive clip 5 are vertically connected to a connecting rod 11. An elastic body 14 in a stretched state is connected between the connecting rod 11 and the insulating shell 1.

[0025] refer to Figure 4 and Figure 5The fixed conductive clip 4 and the movable conductive clip 5 have a corrugated structure with periodic undulations, and their corresponding end faces can interlock. This structural design is beneficial for better clamping of the wires when connecting them, and enhances the stability of the connection. Guide grooves 16 are provided on the corresponding end faces of the fixed conductive clip 4 and the movable conductive clip 5. When the connecting wire is inserted, these guide grooves 16 can not only guide the wire to move down and accurately insert it into the appropriate position, but also effectively increase the clamping contact area between the fixed conductive clip 4, the movable conductive clip 5 and the wire.

[0026] The corrugated structure of the fixed conductive clip 4 and the movable conductive clip 5 has a positive impact on clamping stability and area. In terms of clamping stability, the corrugation can form multi-directional support force, and the nested structure can effectively prevent wire displacement. The fixed conductive clip 4 and the movable conductive clip 5 are made of copper and have a certain degree of elasticity, which can adapt to wires of different diameters. Compared with flat clips that rely solely on friction to maintain clamping, the stability is significantly improved. As for the clamping area, the corrugated structure changes the contact from planar to contour-based contact, greatly increasing the contact area. According to the law of resistance, an increased contact area can reduce contact resistance, improve current conduction efficiency, and facilitate heat dissipation, reducing local overheating. Under the same size conditions, the contact area of ​​the corrugated clip can be significantly increased compared with the flat clip, which effectively improves the contact performance.

[0027] refer to Figure 4 The elastic body 14 is made of rubber band. An annular groove 13 is provided at the middle end of the connecting rod 11. Two symmetrical hooks 12 are fixedly connected to the outer walls of both sides of the insulating shell 1. The middle end of the rubber band is wrapped in the annular groove 13, and its two ends are hung on the hooks 12 and are always in a stretched state. With the help of its elasticity, the movable conductive clip 5 can be automatically moved closer to the fixed conductive clip 4, thereby ensuring sufficient clamping force on the inserted connecting wire.

[0028] It should be noted that, in terms of material selection, the fixed conductive clip 4, the movable conductive clip 5, the copper block 6, the copper conductive sheet 7, and the conductive post 15 are all made of high-quality copper, such as pure copper. Pure copper has excellent conductivity and extremely low resistance, which ensures efficient and stable current transmission. At the same time, pure copper also has good flexibility and ductility, which makes it easier to process and form, and is conducive to producing components that meet the precision requirements. The insulating shell 1, the cover plate 2, and the guide rod 10 are made of halogen-free materials such as nylon PA66, thermoplastic polyester PBT, or liquid crystal polymer LCP. The insulating materials are non-toxic and have excellent flame retardant properties, reaching the V0 flame retardant standard. They possess high safety and environmental protection characteristics and can maintain stable performance even at high temperatures, effectively preventing faults such as short circuits caused by high temperatures. Furthermore, inorganic flame retardants such as aluminum hydroxide and magnesium hydroxide are added during the production of the insulating shell 1, cover plate 2, and guide rod 10. These inorganic flame retardants decompose and absorb heat at high temperatures, releasing water vapor, thereby diluting the oxygen concentration in the surrounding environment, effectively preventing the spread of combustion, and are environmentally friendly and non-toxic, fully complying with environmental protection requirements.

[0029] In practical applications, poor contact between the terminals and connecting wires is one of the key factors leading to damage to terminal blocks. This terminal block mainly improves the poor contact situation to a certain extent by increasing the contact area between the connecting wires and the terminals. When connecting the connecting wires to this environmentally friendly, flame-retardant, highly reliable, and durable terminal block, firstly, the insulation sheath at the end of the connecting wire needs to be stripped. Then, carefully straighten the exposed copper wires by hand. Next, use a screwdriver or a small stick to insert between the two guide rods 10 and the connecting rod 11 on one side of the outer wall of the insulating shell 1, and pull the connecting rod 11 outward. At this time, the two guide rods 10 will pull the movable conductive clip 5 in the socket 3 away from the fixed conductive clip 4, thereby allowing the copper wires to be inserted. Sufficient space is created during insertion. During the insertion process, several guide grooves 16 on the corresponding end faces of the fixed conductive clip 4 and the movable conductive clip 5 can guide the copper wire to move smoothly downwards. The guide grooves 16 also increase the clamping contact area with the copper wire. When the copper wire at the end of the connecting wire is fully inserted, the screwdriver or small stick is pulled out. At this time, the elastic body 14 connecting the connecting rod 11 and the outer wall of the insulating shell 1 pulls the connecting rod 11 closer to the outer wall of the insulating shell 1 with its own elastic tension until the two guide rods 10 push the movable conductive clip 5 to press the copper wire tightly onto the fixed conductive clip 4. This achieves a reliable connection between the connecting wire and the terminal block, ensures stable current transmission, and reduces the risk of failure due to poor contact.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
