Description

Technical Field

[0001] The utility model belongs to the technical field of electrical connection equipment, and in particular relates to an improved wiring terminal. Background Art

[0002] In power transmission connections and distribution settings, wiring terminals are needed to achieve connections between wires and electrical components. There are many types of wiring terminals, among which the nose terminal is the most representative. One of the ends of the terminal is a flat structure, and a wiring hole is opened in the flat end to facilitate the insertion of screws or terminal posts. However, because the electrical components being connected are different, the sizes of the wiring screws or terminal posts on the electrical components will be different. Therefore, the wiring holes of the wiring terminals to be used need to be of different shapes and sizes. The flat end of the existing nose terminal is fixed to the wiring terminal, and the size and shape of the wiring hole of the flat end are fixed and cannot be changed, which cannot meet the wiring requirements of various electrical components. Utility Model Content

[0003] To achieve the above-mentioned purpose, the specific technical solution of the present invention is: an improved terminal block, comprising a terminal head, a terminal piece detachably connected to the terminal head, and a terminal hole for connecting with a screw or a terminal post.

[0004] According to the above technical solution, an extension portion is further provided on the terminal head, and a mounting groove is opened on the extension portion. A mounting block that can cooperate with the mounting groove is provided on the first terminal piece, and the mounting block can be inserted into the mounting groove to realize the connection between the first terminal piece and the terminal head.

[0005] It is worth mentioning that: the mounting groove is provided with two ends, one end is an insertion end, and the other end is a blocking end. The insertion end is open and the blocking end is closed.

[0006] A collar is movably provided on the extension portion. When the terminal head and the terminal piece are connected, the collar can be moved to the joint between the mounting block and the mounting groove to block the joint between the mounting block and the mounting groove.

[0007] According to the above technical solution, the wiring head is further configured to be bendable, and a wiring cavity for inserting the power supply line can be formed in the wiring head by bending the wiring head.

[0008] According to the above technical solution, the mounting groove and the mounting block are both arranged in a dovetail shape, which can prevent the terminal head and the terminal piece from being separated laterally.

[0009] According to the above technical solution, the spring piece is an arc-shaped structure, which can facilitate the disassembly and installation between the terminal head and the terminal piece.

[0010] It is worth mentioning that the other end of the arc-shaped spring piece is distributed longitudinally, which facilitates the spring piece to be squeezed when the mounting block is inserted into the mounting groove.

[0011] According to the above technical solution, the wiring hole further includes a first wiring hole and a second wiring hole.

[0012] Compared with the prior art, the beneficial effects of the present invention are: through the split-type terminal arrangement, the terminal head and the terminal piece can be flexibly assembled. When a terminal piece with a different hole shape or aperture is needed, the terminal piece can be replaced, thereby improving the adaptability of the terminal piece. In addition, when the terminal piece is deformed or damaged, the terminal piece can also be replaced to ensure that the terminal piece can be used normally. The present application has a simple structure and a convenient replacement method, and is suitable for popularization and use. BRIEF DESCRIPTION OF THE DRAWINGS
