Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, and in particular to a new energy terminal block with an insulating protection structure. Background Technology

[0002] In the field of new energy, terminal blocks are key components for power transmission and connection, and their performance directly affects the safety and stability of the entire circuit system. As new energy equipment (such as electric vehicles and energy storage power stations) develops towards higher voltage and higher current, higher requirements are placed on the conductivity, insulation protection, and structural stability of terminal blocks.

[0003] Existing new energy terminal blocks have revealed many shortcomings in actual use: on the one hand, some terminals do not provide good clamping and fixing of the connecting wires, and the connection is achieved only through a single crimping structure, which is prone to loosening under long-term vibration, leading to leakage risk; on the other hand, the insulation protection design is not perfect and it is difficult to provide comprehensive protection for metal connecting parts. Utility Model Content

[0004] The purpose of this utility model is to provide a new energy terminal block with an insulating protection structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution, which includes a terminal main housing, a reinforcing component movably disposed on the outer wall of the terminal main housing, and a detachable insulating top cover disposed on the top of the reinforcing component.

[0006] As a preferred embodiment of this utility model, the main housing of the terminal has several pairs of installation chambers, each of which is equipped with an energized shell. The energized shell is equipped with a pressure member, and the corresponding energized shells are connected by a connector. The top of the main housing of the terminal is threaded with several pressing bolts corresponding to the positions of the energized shells. The pressing bolts pass through the energized shells and abut against the pressure member.

[0007] As a preferred embodiment of this utility model, the front and back of the terminal main housing are provided with several plug-in ports that communicate with several installation chambers respectively. Each plug-in port is provided with a lower semi-circular clamp. The front and rear sides of the terminal main housing are symmetrically provided with sliding grooves, and the bottom left and right sides of the terminal main housing are symmetrically provided with locking grooves.

[0008] As a preferred embodiment of this utility model, the reinforcing component includes a sliding frame sleeved on the outside of the terminal main housing. A slider is provided on the inner wall of the sliding frame at the position corresponding to two sliding grooves. The slider is movably disposed in the sliding groove. An upper semi-circular clamp is provided at the bottom of the sliding frame at the position corresponding to several lower semi-circular clamps. Slots are symmetrically opened on the bottom left and right sides of the sliding frame. A rotating shaft is movably disposed in the slot. An L-shaped clamp is provided on the rotating shaft. Fixing blocks are symmetrically arranged on the top two sides of the sliding frame. A T-shaped groove is opened in the fixing block. A magnetic column is inserted into the fixing block.

[0009] As a preferred embodiment of this utility model, T-shaped blocks are symmetrically arranged on both sides of the insulating top cover. The T-shaped blocks are inserted into the T-shaped grooves. Insertion holes are opened on the T-blocks corresponding to the positions of the magnetic pillars. Insulating plugs are provided on the inner top surface of the insulating top cover at the positions of several pressing bolts.

[0010] As a preferred embodiment of this utility model, insulating rubber pads are provided inside both the lower and upper semicircular clamps.

[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: This utility model provides secondary fixation of the connecting wires on the outside of the terminals by adding reinforcement components. The upper and lower semi-circular clamps, together with the elastic deformation and reset effect of the insulating rubber pads, combined with the mechanical limiting of the L-shaped clamp, form a double reinforcement of elastic tightening and rigid fixation. This effectively prevents the connecting wires from loosening due to external pulling or vibration, and avoids leakage. It is especially suitable for high-frequency vibration application scenarios in new energy equipment.

[0012] This invention utilizes an insulating top cover that, through the cooperation of a T-shaped block and a fixing block, combined with the tight fixation of a magnetic post, completely covers the main housing of the terminal and the wiring area, forming a closed insulating space. The insulating plug inside the top cover directly covers the pressing bolt, preventing metal parts from being exposed and structurally blocking the risk of electric shock. Insulating pads are provided on the inner sides of the upper and lower semi-circular clamps in the reinforcement assembly, which not only enhances the friction on the connecting wire to improve clamping stability, but also isolates the connecting wire from the metal clamp, further strengthening the insulation effect and meeting the high insulation level requirements of new energy equipment.

Detailed Implementation

[0015] 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 specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0016] like Figure 1-6 As shown, the new energy terminal block with an insulating protection structure proposed in this utility model is mainly composed of three parts: terminal main housing 1, reinforcing component 2, and insulating top cover 3. The terminal main housing 1 has several pairs of mounting chambers 10. Each pair of mounting chambers 10 is a wiring unit. Each set of mounting chambers 10 has two corresponding energized shells 11 for conductive connection of the connecting wires. The two corresponding energized shells 11 are fixedly connected by connectors 12 to ensure that the current can be stably conducted between the corresponding energized shells 11. Each energized housing 11 is movably provided with a pressure member 13, which can move up and down along the vertical direction of the energized housing 11; the top of the terminal main housing 1 is provided with threaded holes corresponding to the positions of each energized housing 11, and the pressing bolt 14 is threadedly connected to the terminal main housing 1 through the threaded holes, and the bottom end of the pressing bolt 14 passes through the energized housing 11 and abuts against the pressure member 13. By turning the pressing bolt 14, the pressure member 13 can be driven to cooperate with the energized housing 11 to clamp the connecting wire; The front and back of the terminal main housing 1 are provided with plug-in ports 15 that correspond one-to-one with the mounting chamber 10. The connecting wire can enter the mounting chamber 10 through the plug-in port 15 and contact the energized housing 11. A lower semi-circular clamp 16 is fixedly provided below each plug-in port 15 to cooperate with the reinforcing component 2 to clamp the connecting wire on the outside of the terminal. The terminal main housing 1 has symmetrical sliding grooves 19 on the front and rear sides to guide the sliding of the reinforcing component 2; and symmetrical slots 18 on the left and right sides of the bottom to fix the limiting structure of the reinforcing component 2. The reinforcing component 2 includes a sliding frame 20 sleeved on the outside of the terminal main housing 1. A slider 21 is fixedly installed on the inner wall of the sliding frame 20 at the position corresponding to the sliding groove 19 of the terminal main housing 1. The slider 21 is embedded in the sliding groove 19 and can slide up and down along the sliding groove 19, so that the sliding frame 20 can move up and down relative to the terminal main housing 1. An upper semi-circular clamp 22 is fixedly installed at the bottom of the sliding frame 20 at the position corresponding to the lower semi-circular clamp 16 of the terminal main housing 1. The upper semi-circular clamp 22 and the lower semi-circular clamp 16 are opposite to each other, and insulating pads 17 are fixedly attached to the inner side of both. When closed, they can clamp the connecting wire together. The bottom of the left and right sides of the sliding frame 20 are symmetrically provided with slots 23. An L-shaped clamp 25 is movably connected in the slots 23 through a rotating shaft 24. The L-shaped clamp 25 can rotate around the rotating shaft 24. When the L-shaped clamp 25 is rotated, its bottom end can be inserted into the slot 18 at the bottom of the terminal main housing 1 to fix the position of the sliding frame 20. Fixing blocks 26 are symmetrically fixed on both sides of the top of the sliding frame 20. T-shaped grooves 27 are opened in the fixing blocks 26, and a channel communicating with the T-shaped grooves 27 is opened through the fixing blocks 26. A magnetic column 28 is inserted in the channel for fixing the insulating top cover 3. T-shaped blocks 30 are symmetrically fixed on both sides of the insulating top cover 3. The T-shaped blocks 30 are adapted to the T-shaped grooves 27 of the fixing block 26 and can be inserted along the T-shaped grooves 27 to achieve horizontal positioning. The T-shaped blocks 30 have insertion holes 31 corresponding to the magnetic posts 28. When the T-shaped blocks 30 are fully inserted into the T-shaped grooves 27, the magnetic posts 28 can pass through the holes of the fixing block 26 and be inserted into the insertion holes 31 of the T-shaped blocks 30. Through the magnetic adsorption of the magnetic posts 28, the T-shaped blocks 30 and the fixing block 26 are firmly connected, realizing the detachable fixing of the insulating top cover 3. An insulating plug 32 is fixedly installed on the inner top surface of the insulating top cover 3 at the position corresponding to the pressing bolt 14 of the terminal main housing 1. When the insulating top cover 3 is installed, the insulating plug 32 can cover the pressing bolt 14 to enhance the insulation protection effect.

[0017] First, secure the connecting wires: Insert the wire terminals into the insertion port 15 of the terminal housing 1, ensuring the terminals are directly below the clamping member 13; then, use a screwdriver to turn the lowering bolt 14 clockwise. Under the pushing force of the bolt, the clamping member 13 will move downwards until it engages with the power-conducting housing 11, firmly clamping and securing the wire terminals; follow the above steps to complete the securing of all connecting wires according to actual wiring requirements. Next, the connecting wire on the outside of the terminal is reinforced: manually press down the slide frame 20, so that the slide frame 20 moves the upper semi-circular clamp 22 closer to the lower semi-circular clamp 16. The two work together to initially clamp the front end of the connecting wire located on the outside of the terminal main housing 1. Under the continuous downward pressure, the insulating rubber pad 17 on the inner side of the upper and lower semi-circular clamps 16 will deform, leaving space for subsequent fixation. At this time, rotate the L-shaped clamps 25 on both sides so that their bottom ends are accurately inserted into the corresponding slots 18. Then release the pressure on the slide frame 20. The insulating rubber pad 17 will automatically recover due to elasticity and push upward, causing the upper semi-circular clamp 22 to tighten. With the limiting effect of the L-shaped clamps 25, the two L-shaped clamps 25 firmly fix the upper semi-circular clamp 22, thereby achieving a stable clamping of the connecting wire. Finally, complete the installation of the insulating top cover 3: Align the T-shaped blocks 30 on both sides of the insulating top cover 3 with the T-shaped grooves 27 of the fixing block 26 on the terminal main housing 1, and insert them smoothly along the groove direction; after the T-shaped blocks 30 are fully inserted, pass the magnetic post 28 through the reserved hole on the fixing block 26, and insert it into the corresponding insertion hole 31 of the T-shaped block 30. Utilize the magnetic adsorption effect of the magnetic post 28 to achieve a tight connection between the fixing block 26 and the T-shaped block 30, and finally complete the firm fixation of the insulating top cover 3, ensuring that the entire terminal structure has reliable insulation protection performance.
