Description

Technical Field

[0001] This utility model relates to the field of electrical connection components technology, specifically a multi-bend terminal block. Background Technology

[0002] Terminal blocks, as key components for electrical connections, are widely used in various electrical equipment. A search revealed Chinese patent publication number CN222851693U, which discloses multi-bend terminal blocks with fixed bending angles. These angles cannot be flexibly adjusted according to different usage scenarios. When faced with complex wiring layouts or confined installation spaces within electrical equipment, they are difficult to adapt to diverse connection needs. Often, additional adapters are required to achieve wiring reversals. This not only increases the complexity of wiring connections but may also increase the risk of malfunctions due to the increased number of adapters. Furthermore, it leads to cumbersome installation processes and reduced assembly efficiency, failing to meet the requirements of modern electrical equipment for the flexibility and adaptability of connection components.

The embodiments of this utility model will be described below based on its overall structure.

[0022] Reference Figures 1 to 5 In this embodiment of the present invention, a multi-bend terminal block includes: a terminal block body 1 and a conductive terminal body 2. A hinge block 3 is fixedly connected to the side of the terminal block body 1. A multi-segment bend structure 4 is hinged to the side of the hinge block 3. The other end of the multi-segment bend structure 4 is connected to the conductive terminal body 2. The multi-segment bend structure 4 consists of two sets of sequentially connected bend segments 41. An angle positioning bead 42 and a positioning groove 43 are provided at the rotation point between the bend segments 41. The included angle between adjacent bend segments 41 is adjustable. The multi-segment bend structure 4 is the core component for achieving angle adjustment. The two sets of bend segments 41 are connected by rotation to form a movable joint. The interlocking action of the angle positioning bead 42 and the positioning groove 43 can achieve locking of any right angle during the adjustment process. When it is necessary to adapt to different line routes, the multi-segment bend structure 4 is rotated as a whole by the hinge block 3, and the included angle between the bend segments 41 is adjusted at the same time, so that the conductive terminal body 2 can be accurately aligned with the target connection position to meet the turning requirements in narrow spaces or complex layouts.

[0023] The terminal block body 1 has multiple sets of wiring slots 5 on its side. Each set of wiring slots 5 has a slot 6 on both sides. A hinged rotating frame 7 is connected to the slot 6. A clamping plate 8 is connected to the side of the hinged rotating frame 7. The surface of the clamping plate 8 is provided with anti-slip texture 9. When wiring, multiple sets of wiring slots 5 can be used to connect multiple lines at the same time. When the wire is inserted into the wiring slot 5, the wire contacts the anti-slip texture 9 on the surface of the clamping plate 8, which will drive the hinged rotating frame 7 and the clamping plate 8 to rotate inward. The gap between the two sets of clamping plates 8 becomes smaller, thereby clamping and fixing the wire. With the limiting effect of the slot 6, the wire can be prevented from loosening and falling off under vibration and other working conditions, ensuring stable conductive contact between the wire and the terminal block body 1.

[0024] The conductive terminal body 2 has multiple sets of conductive ports 10 on its side. The conductive ports 10 have guide slopes 11 inside and anti-detachment barbs 12 on both sides. The entrance of the conductive ports 10 has an flared structure. The conductive terminal body 2 connects to the external circuit through the multiple sets of conductive ports 10. The flared structure at the entrance of the conductive ports 10 facilitates the quick insertion of the plug. The guide slopes 11 further guide the plug to enter smoothly. The anti-detachment barbs 12 on both sides undergo elastic deformation after the plug is inserted and clamp the outer wall of the plug to prevent accidental detachment. At this time, the current is conducted from the terminal body 1 through the multi-section bending structure 4 to the conductive terminal body 2, and the circuit connection is completed through the conductive ports 10.

[0025] Both sides of the terminal block body 1 and the conductive terminal body 2 are fixedly connected with fixing ears 13. The fixing ears 13 are provided with mounting holes 14. A rubber buffer pad 15 is provided in the mounting holes 14. The mounting holes 14 on the fixing ears 13, together with the rubber buffer pad 15, can securely install the terminal block body 1 and the conductive terminal body 2 on the equipment. The rubber buffer pad 15 can absorb the vibration energy during the operation of the equipment and avoid loosening of the connection due to long-term vibration.

[0026] Both the outer surfaces of the terminal block body 1 and the conductive terminal block body 2 are covered with an insulating protective sleeve 16. The insulating protective sleeve 16 is made of high-temperature resistant silicone rubber material. The insulating protective sleeve 16 forms a reliable insulating barrier, which can prevent short circuit risk and withstand high and low temperature environments.

[0027] The side of the terminal block body 1 is provided with a nameplate 17, which is marked with circuit identification information. The nameplate 17 makes it easy for operators to quickly identify the circuit function and improve maintenance efficiency.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] The working principle of this utility model is as follows: When using this multi-bend terminal block, firstly, according to the actual circuit layout and connection requirements, the multi-segment bending structure 4 is rotated by the hinge block 3, and the included angle between the two sets of bending segments 41 is adjusted. The required angle is locked by the engagement of the angle positioning bead 42 and the positioning groove 43, so that the conductive terminal body 2 is aligned with the target connection position. Then, the wires to be connected are inserted into the multiple sets of wiring slots 5 on the side of the terminal body 1. During the insertion process, the wires contact the anti-slip texture 9 on the surface of the clamping plate 8, which drives the hinge rotating frame 7 and the clamping plate 8 to rotate inward, so that the gap between the two sets of clamping plates 8 is reduced to clamp the wires. At the same time, the limiting effect of the slot 6 ensures that the wires are stable and do not loosen. Then, the external circuit... The plug is aligned with the flared structure of the conductive port 10 on the side of the conductive terminal body 2 and inserted into the conductive port 10 under the guidance of the guide slope 11. At this time, the anti-detachment barb 12 undergoes elastic deformation and clamps the outer wall of the plug to prevent it from falling off. Then, the terminal body 1 and the conductive terminal body 2 are fixed to the equipment through the mounting hole 14 on the fixing ear 13 and the bolt. The rubber buffer pad 15 in the mounting hole 14 absorbs the vibration of the equipment to prevent the connection from becoming loose. Finally, the circuit function is identified by the nameplate 17 on the side of the terminal body 1. At this time, the current is conducted from the terminal body 1 through the multi-section bending structure 4 to the conductive terminal body 2, and then completes the circuit connection through the conductive port 10. Throughout the process, the insulating protective sleeve 16 provides insulation protection to ensure the safe and stable operation of the device.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
