Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a cable connection terminal structure for a power distribution cabinet. Background Art

[0002] Terminal blocks are accessories used to achieve electrical connections, and play important roles such as connection and current carrying. Currently, the most commonly used terminal blocks on distribution lines and equipment are crimp terminals. These crimp terminals require the use of special crimping tools, such as mechanical crimping pliers and hydraulic crimping pliers, and require matching suitable dies. The crimping tools are used to crimp the terminal blocks using a combination of confining pressure and voltage. The terminal blocks undergo plastic deformation under the external force of the crimping tools, thereby compressing the wire cores and completing the installation of the terminal blocks.

[0003] However, due to the wide variety of sizes available for crimp terminals, if the size of the crimping die used by construction workers doesn't match the crimping terminal, the terminal can easily be damaged or deformed, making it impossible to compress the wire. Furthermore, crimping terminals require specialized crimping tools, resulting in complex processes and low efficiency. Furthermore, crimp terminals cannot be reused after installation, limiting their flexibility and leading to resource waste. Summary of the Invention

[0004] In order to overcome the above-mentioned shortcomings, the purpose of the utility model is to provide a cable connection terminal structure for a distribution cabinet. A terminal column with a spring is arranged inside the cable structure, and pressure is applied on the outside by tightening a nut to ensure the stability of the wire. At the same time, a cable locking buckle is provided inside the nut to ensure that the connected cable will not slip off. The terminal is easy to install and can be reused, which can effectively improve the installation efficiency of the terminal.

[0005] The technical solution of the present utility model is a cable connection terminal structure for a distribution cabinet, comprising a fixed wall of the distribution cabinet, a terminal fixing seat being provided on the fixed wall of the distribution cabinet, a clamping terminal mounted on the terminal fixing seat, and a nut adapted to the clamping terminal, wherein the clamping terminals are divided into four groups and a separation gap is provided between each group; a terminal column is provided in the clamping terminal, a wire spring is provided on the terminal column, and a spring is provided between the wire spring and the terminal column; a cable locking buckle corresponding to the front end of the clamping terminal is provided in the nut.

[0006] Furthermore, in order to tighten the inner wire after the nut is installed in place, the inner diameter of the bottom of the clamping terminal gradually increases as it moves toward the top.

[0007] Furthermore, the clamping terminal is provided with an external thread.

[0008] Furthermore, an internal thread is provided in the nut, and a threading hole is also provided on the nut.

[0009] Furthermore, in order to ensure that the cable does not slip off, the cable locking buckle is installed in the nut close to the threading hole, and the cable locking buckle changes with the vertical position of the nut.

[0010] Furthermore, in order to ensure that the compression terminal is pressed inwardly under the action of the nut, the front half of the compression terminal is equally divided into four groups and a separation gap is provided between each group.

[0011] Furthermore, in order to better insert the wire, the front part of the terminal column is tapered.

[0012] The beneficial effect of the present utility model is that a cable connection terminal structure of a distribution cabinet includes a terminal fixing seat, a clamping terminal installed on the terminal fixing seat, and a nut adapted to the clamping terminal. When in use, the inner wire is passed through the nut and extended into the clamping terminal. The front end body of the clamping terminal is divided into four groups, and there is a separation gap between each group. Under the pressure of the nut, each group is compressed inward to reduce the separation gap. A terminal column is provided inside the clamping terminal, and two wire springs are provided on the terminal column. The inner wire is inserted into the clamping terminal and is evenly distributed between the wire springs and the inner wall of the clamping terminal. When the nut is tightened, the clamping terminal is squeezed inward to fix the wire in the clamping terminal. A cable locking buckle is provided in the nut. When the nut is tightened, the front end of the clamping terminal supports the cable locking buckle, and the lower part of the cable locking buckle is buckled on the cable sheath to fix the cable column, ensuring that the cable will not fall off under the action of external force during use, thereby ensuring the safety of the cable connection.

The clamping terminal 3 is provided with an external thread 34, and the nut 4 is provided with an internal thread 43. The nut is installed on the clamping terminal. During the installation process, the nut will apply a force to the clamping terminal and maintain it after the installation is completed, so that the separation gap between the groups of clamping terminals is reduced. The internal space is reduced to compress the internal wire 6 inside the clamping terminal. A threading hole 42 is provided on the nut 4 to facilitate threading.

[0025] The utility model discloses a cable connection terminal structure for a distribution cabinet, comprising a terminal fixing seat, a clamping terminal installed on the terminal fixing seat, and a nut adapted to the clamping terminal.
