Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, and in particular to a wiring device. Background Technology

[0002] Terminal blocks are fundamental components used to achieve electrical connections. They are widely used in power equipment, industrial control systems, electronic appliances, and communication equipment. Their main function is to reliably fix wires to circuit interfaces and transmit electrical signals or energy through metal conductors. Traditional terminal blocks typically consist of an insulated body and conductive components.

[0003] Traditional terminal blocks typically use screws to press and secure the terminals when connecting wires. This method is cumbersome, requiring users to tighten and loosen the screws with tools every time maintenance or wiring needs to be performed, which affects the customer experience. In addition, when the ambient temperature changes significantly, the metal expands and contracts due to temperature changes, which may cause the originally tightened screws to loosen, further affecting the electrical connection and causing sparking or unstable signal transmission. Utility Model Content

[0004] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a wiring device that solves at least one of the aforementioned technical problems. It has the advantages of eliminating the need for screws to fix the terminals, fixing the wires by snap-fit, resulting in a better customer experience and ensuring stable and reliable contact.

[0033] Please refer to Figures 1 to 7This utility model provides a wiring device, including: a first wiring board 100, a second wiring board 200, and a snap-fit ​​assembly. The first wiring board 100 is provided with a first snap-fit ​​groove 130 penetrating its top and bottom. The bottom of the second wiring board 200 is provided with a second snap-fit ​​groove 201 corresponding to the first snap-fit ​​groove 130.

[0034] The snap-fit ​​assembly includes a mounting base 301 and a mounting cover plate 302 disposed above the mounting base 301. The top of the mounting cover plate 302 is provided with a through groove 303 that extends through its top and bottom and corresponds to the second snap-fit ​​through groove 201. The top of the mounting base 301 is provided with a receiving groove 304. An elastic element 305 and a snap-fit ​​element 306 disposed on top of the elastic element 305 are disposed in the receiving groove 304. An installation gap 307 is provided between the mounting base 301 and the mounting cover plate 302. The second terminal block 200 is disposed in the installation gap 307.

[0035] When it is necessary to connect the first terminal block 100 and the second terminal block 200, simply insert the first terminal block 100 into the installation gap 307. Under the action of the elastic member 305, the snap-fit ​​member 306 will pass through the first snap-fit ​​groove 130 and the second snap-fit ​​groove 201, and push the first terminal block 100 to contact the second terminal block 200. When it is necessary to remove the first terminal block 100, simply press the snap-fit ​​member 306 down through the through groove 303 so that the snap-fit ​​member 306 overcomes the elastic force of the elastic member 305 and sinks down, thereby pulling the first terminal block 100 out of the installation gap 307.

[0036] The first locking slot 130 and the second locking slot 201 can be rectangular, trapezoidal, or other polygonal shapes to achieve a better locking effect. The locking component 306 can be designed as a block, with a raised structure on its top to enhance locking stability. The elastic component 305 can be made of elastic materials such as helical springs, disc springs, or elastic rubber. The width of the installation gap 307 can be adjusted according to the thickness of the terminal block to ensure that the terminal block can be smoothly inserted and remain stable. This application uses the first terminal block and the second terminal block for contact connection. The contact area between the first contact plate and the second contact plate is relatively large, avoiding the situation where the terminal block overheats due to a small contact surface. Furthermore, the first terminal block, the second terminal block, and the locking assembly constitute a terminal block group, which can be increased to form multiple terminal block groups, and avoids the occurrence of unstable electrical connections caused by loosening of screws due to thermal expansion and contraction.

[0037] This technical solution enables quick connection and disassembly of the terminal block through a snap-fit ​​assembly, avoiding the cumbersome process of tool-based fixing using traditional screws. The snap-fit ​​component 306 automatically engages under the action of the elastic element 305, ensuring simple operation and reliable connection. The through-slot 303 design allows for easy disassembly with a simple press, improving maintenance convenience. The installation gap 307 ensures accurate positioning of the terminal block and maintains a stable connection.

[0038] In this embodiment, the first terminal block 100 includes a connecting portion and a first conductive protrusion 103 for assembling wires. The connecting portion enables the first terminal block 100 to make contact and conduct electricity with the second terminal block, and the first conductive protrusion 103 is used to achieve electrical connection with the wires. The first conductive protrusion 103 can be made of a metal material, such as copper or a copper alloy, to ensure good conductivity. The first conductive protrusion 103 can be configured as a column, a sheet, or other shape suitable for connecting with wires. The connecting portion is integrally formed with the first conductive protrusion 103.

[0039] Specifically, the connection between the first conductive protrusion 103 and the wire can be achieved by crimping, welding, or other methods. The first conductive protrusion 103 can be located on the side of the connection portion or in other easily accessible positions. Furthermore, multiple first conductive protrusions 103 can be provided to facilitate the simultaneous connection of multiple wires.

The second side plate 302.2 is mounted on one side of the mounting base 301 and covers the second limiting mounting groove 309. In this embodiment, due to the presence of the cover, the first and second wiring boards of this application are less susceptible to the influence of external objects, increasing the safety of this application during use.

[0045] Specifically, the second top plate 302.1 and the second side plate 302.2 are manufactured using an integral molding process to ensure structural strength and integrity. The second top plate 302.1 covers the first limiting mounting groove 308 on the top of the mounting base 301 to prevent external foreign objects from entering and affecting the operation of internal components. The second side plate 302.2 extends along the side of the mounting base 301, completely obscuring the second limiting mounting groove 309, forming a semi-enclosed protective structure. As a preferred embodiment, the second top plate 302.1 and the mounting base 301 can be connected by snap-fit ​​or fixed with screws, and the mating surfaces of the second side plate 302.2 and the side wall of the mounting base 301 can be provided with anti-slip textures to enhance assembly stability.

[0046] Furthermore, the connection between the second top plate 302.1 and the second side plate 302.2 is rounded.

[0047] Specifically, rounding refers to the rounded transition at the corner where the second top plate 302.1 and the second side plate 302.2 meet. As a preferred embodiment, the rounded corner can be achieved by milling with a CNC machine tool, or it can be formed directly in the sheet metal forming stage using a stamping die.

[0051] Specifically, the main body 315 serves as the primary support structure for the snap-fit ​​member 306. Its bottom second limiting protrusion 311 is used to fix the top of the spring, preventing the spring from shifting during compression or rebound. A snap-fit ​​protrusion 316 is located on the top of the main body 315, cooperating with the first snap-fit ​​through-slot 130, the second snap-fit ​​through-slot 201, and the through-slot 303 to achieve a locking function. A first inclined guide surface 314 is located at the end of the snap-fit ​​protrusion 316 away from the side plate, facilitating the downward movement of the snap-fit ​​member 306 when the first wiring plate 100 is inserted. In a preferred embodiment, the second limiting protrusion 311 can be a cylindrical boss structure with a diameter slightly smaller than the inner diameter of the spring to achieve a tight fit.

[0052] In this embodiment, a second inclined guide surface 317 is provided at one end of the main body 315 away from the first side plate 120, and a third inclined guide surface 318 is provided at the top of the main body 315, which is connected to the first inclined guide surface 314 and the second inclined guide surface 317.
