[0003] Currently, existing terminal blocks often suffer from insufficient friction between the inlet hole and the wire during use, leading to the wire loosening or even falling off under long-term vibration, pulling, and other external forces, causing faults such as poor contact and short circuits. In addition, the installation and maintenance process of existing terminal blocks is relatively cumbersome, often requiring complete disassembly of the outer casing to operate the internal wire clamping components, resulting in low maintenance efficiency and failing to meet the needs of rapid emergency repairs and routine maintenance.

[0004] Therefore, it is necessary to provide a terminal block with an anti-slip structure for the inlet hole to solve the above problems. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, the present invention provides a terminal block with an anti-slip structure for the inlet hole, comprising a housing 1, an installation groove 2 on the top of the housing 1, and inlet ports 3 symmetrically opened at both ends of the housing 1. A connector 4 is installed inside the installation groove 2. Inlet grooves 5 are symmetrically opened on both sides of the connector 4 and are connected to the inlet ports 3. The groove wall of the inlet groove 5 is provided with several evenly arranged anti-slip textures 6. The top of the connector 4 is provided with symmetrical pressure ports 7, and the two pressure ports 7 are respectively located above and connected to the two inlet grooves 5. A pressure screw 8 is threaded inside the pressure port 7. A hexagonal groove 9 is opened on the top of the pressure screw 8. A cover 10 is snapped onto the top of the installation groove 2. A grounding hole 11 is opened on the top of the cover 10. A locking block 12 is snapped onto the top of the grounding hole 11.

[0022] refer to Figure 1 , Figure 3 and Figure 4 The front and rear sides of the housing 1 are symmetrically provided with card interfaces 13, and the top of the cover 10 is symmetrically fixedly connected with card hooks 14, and the card hooks 14 are engaged with the card interfaces 13.

[0023] As a technical optimization of this utility model, the installation and removal of the cover 10 can be completed without additional tools through the snap-fit ​​structure of the hook 14 and the card interface 13, which is convenient to operate and at the same time ensures that the cover 10 is firmly connected to the shell 1 to prevent accidental detachment.

[0024] refer to Figure 3 and Figure 4 The top of the cover 10 is symmetrically provided with operation ports 15, and the two operation ports 15 are located directly above the two wire pressing ports 7 respectively. The bottom of the operation port 15 is fixedly connected to the limit frame 16, and the bottom of the limit frame 16 is in contact with the connector 4.

[0025] As a technical optimization of this utility model, by aligning the operating port 15 with the wire pressing port 7, the wire pressing screw 8 can be directly tightened through the operating port 15 without disassembling the cover 10, simplifying the maintenance process. The limiting frame 16 is used to limit the swing range of the wire pressing screw 8, ensuring that it is accurately aligned with the wire pressing port 7 when tightening, and avoiding installation errors or component damage caused by misalignment.

[0026] refer to Figure 3 The cross-sectional area of ​​the operating port 15 is smaller than that of the wire pressing screw 8, and the cross-sectional area inside the limiting frame 16 is larger than that of the wire pressing port 7.

[0027] As a technical optimization of this utility model, by making the operating port 15 smaller than the wire pressing screw 8, the wire pressing screw 8 can be prevented from accidentally falling off the operating port 15. At the same time, the limiting frame 16 is larger than the wire pressing port 7, providing sufficient room for the wire pressing screw 8 to ensure that it can be screwed in or out smoothly. This size design balances the ease of operation and the stability of the components, making it easy for tools to be inserted and operated, while avoiding the wire pressing screw 8 from tilting or getting stuck due to excessive space.

[0028] refer to Figure 1 and Figure 2 An embedding block 17 and an embedding groove 18 are fixedly connected to both sides of the housing 1, and the embedding block 17 and the embedding groove 18 are used in conjunction.

[0029] As a technical optimization of this utility model, multiple housings 1 can be spliced ​​and combined through the embedded block 17 and the embedded groove 18, and the number of wiring can be flexibly expanded according to actual needs, thereby improving the applicability and integration of the device and reducing installation costs.

[0030] refer to Figure 1 and Figure 2 Mounting blocks are symmetrically fixedly connected to the front and rear sides of the bottom of the housing 1, and mounting openings are provided on the top of the mounting blocks.

[0031] As a technical optimization of this utility model, the mounting block and mounting port facilitate the fixing of the wiring terminals to the circuit board, equipment housing, etc. by screws or other fasteners, ensuring that the device remains stable during vibration or long-term use and avoiding displacement from affecting the reliability of wiring.

[0032] The working principle and usage process of this utility model are as follows: When using this terminal block, firstly, select multiple housings 1 according to the expansion requirements of the circuit and interlock them. That is, the embedding blocks 17 and embedding grooves 18 on the side of the housing 1 can realize the splicing of multiple sets of housings 1 to meet the expansion requirements of complex circuits. Then, use the mounting port of the mounting block at the bottom of the housing 1 to fix the terminal block to the equipment panel or circuit board to ensure the structural stability. Then, strip an appropriate length of insulation layer from the wire and insert the wire from the inlet port 3 at both ends of the housing 1, extending through the inlet groove 5 to below the crimping port 7. At this time, the anti-slip texture 6 on the groove wall of the inlet groove 5 increases the friction of the contact surface to prevent the wire from loosening or falling off when pulled or vibrated. Then, use a hex screwdriver to tighten the crimping screw 8. The threaded terminal 10 is screwed into the wire clamping port 7, and its bottom gradually presses the wire, further fixing the connection point and ensuring the stability of the electrical connection. During the use of this terminal, the cover 10 is engaged with the clamping interface 13 of the housing 1 via the hook 14, sealing the mounting groove 2 and protecting the internal wiring components 4, wire clamping screws 8, and other components. When it is necessary to remove the wire, the hexagonal screwdriver is aligned with the wire clamping port 7 and the hexagonal groove 9 through the operating port 15, and the wire clamping screw 8 is turned in the opposite direction to loosen the wire. There is no need to disassemble the entire cover 10, simplifying maintenance operations. This achieves the stability of the wire connection, the convenience of operation and maintenance, the flexibility of structural expansion, and the reliability of installation and fixation. It is suitable for electrical scenarios that require frequent wiring or have high requirements for safety and durability.
