Description

Technical Field

[0001] This utility model relates to the field of electrical equipment wiring technology, and in particular to a terminal wiring assembly and the terminal block formed by assembling it. Background Technology

[0002] When wiring electrical cables in confined spaces, smaller terminal blocks are typically used. However, for irregularly shaped spaces, such as circular or sector-shaped areas, terminal blocks arranged in straight lines or rectangles cannot effectively conform to the curves of the sector, resulting in a significant waste of edge space. This leads to lower space utilization and makes it impossible to effectively wire thicker cables.

[0003] For example, during the installation and wiring of temperature-sensing intelligent control devices for heating equipment, commonly used terminal blocks cannot adapt to the fan-shaped space where the control device is installed. Traditional terminal block designs are usually of fixed length and shape, making it difficult to accommodate the varying sizes and angles of fan-shaped spaces. The wiring area inside the fan-shaped space is narrow and irregular, requiring operators to bend their bodies or wrists when wiring, increasing the difficulty and time required. Using existing terminal blocks for wiring results in a chaotic layout, potentially obscuring wiring markings, increasing wiring errors and the difficulty of later maintenance. Utility Model Content

[0004] The purpose of this utility model is to solve the above problems by providing a terminal wiring assembly and the terminal block formed therefrom. By arranging the terminal wirings in a fan-shaped structure, it can meet the wiring requirements of related equipment, saving space and making the wiring process convenient and safe.

[0021] When the two shells 3 are spliced ​​together, the locking pin 5 of the right shell 3 is inserted into the locking hole 6 of the left shell 3 to achieve the docking of the two shells 3. Since the positions of the locking hole 6 and the locking pin 5 are corresponding, the locking hole 6 is a blind hole set inside the locking pin 5 on the closed side 7. The diameter of the locking hole 6 is smaller than the diameter of the locking pin 5. The front end of the locking pin 5 is a thinner end, which is used for clearance fit or slightly tight fit when installing with the blind hole.

[0022] See appendix Figure 6 , 7 8. The lock button 4 includes a lock body 9 and a button 10. The lock body 9 is located inside the housing 3.
