A lightweight welding plate terminal

Abstract

The utility model discloses a lightweight welding plate terminal, which comprises a terminal body and a reinforcing cushion block. The terminal body is in a U-shaped structure. The reinforcing cushion block is arranged inside the terminal body, and the connecting parts at both ends thereof are correspondingly matched with two connecting holes on the terminal body. The transverse length of the reinforcing part in the middle of the reinforcing cushion block is greater than the width of the connecting part and less than the length of the terminal body. The threaded hole arranged in the middle of the reinforcing part corresponds to the threaded hole on the terminal body. Tin plating layers are arranged on both the terminal body and the reinforcing cushion block. By adopting the above technical scheme, the material used in manufacturing the reinforcing cushion block is relatively reduced, thus saving materials and manufacturing costs, and can also reduce the weight, thereby reducing the weight of the welding plate terminal. In addition, by arranging tin plating layers on both the terminal body and the reinforcing cushion block, oxidation of the terminal body and the reinforcing cushion block can be prevented, ensuring that the electrical conductivity is not affected during use.

Technical Field 2 , Figure 1

[0001] The utility model relates to the technical field of terminals, and particularly relates to a lightweight solder plate terminal. Background Art

[0002] Terminal blocks are gradually widely used in various fields, playing a connecting role in transmitting electrical signals and conducting electricity, thus reducing the workload and consumption of production costs, bringing many conveniences to production and use, and avoiding many troubles.

[0003] The solder plate terminals used on circuit boards are generally made of copper and have a relatively thin wall thickness. In order to improve the firmness of the connection of the upper pressure screw, a reinforcing pad is provided inside the solder plate terminal. As shown in the attached drawings of the specification, the connecting parts A21 at both ends of the reinforcing pad A2 are matched with the connecting holes on the solder plate terminal A1, and the threaded part of the pressure screw A3 is in threaded cooperation with the threaded holes on the solder plate terminal and the threaded holes on the reinforcing pad. The transverse length of the reinforcing pad on the existing solder plate terminal is the same as the length of the solder plate terminal, resulting in a relatively heavy weight of the solder plate terminal, relatively more materials used in production, and a relatively high production cost. Figure 1 、 2 As shown, the connecting parts at both ends of the reinforcing pad A2 are matched with the connecting holes on the solder plate terminal A1, and the threaded part of the pressure screw A3 is in threaded cooperation with the threaded holes on the solder plate terminal and the threaded holes on the reinforcing pad. The transverse length of the reinforcing pad on the existing solder plate terminal is the same as the length of the solder plate terminal, resulting in a relatively heavy weight of the solder plate terminal, relatively more materials used in production, and a relatively high production cost.

The threaded hole provided in the middle of the reinforcing part corresponds to the threaded hole on the terminal body. Tin plating layers are provided on both the terminal body and the reinforcing pad.

[0007] By adopting the above technical solution, by controlling the transverse length of the reinforcing part to be greater than the width of the connecting part and less than the length of the terminal body, compared with the structure of the reinforcing pad on the existing solder plate terminal, the materials used in the production of the reinforcing pad are relatively reduced, the materials are saved, the production cost is saved, and the weight can be reduced, thereby reducing the weight of the solder plate terminal.
