Description

Technical Field

[0001] The utility model relates to an integrated structure of a power supply housing and a wiring terminal, belonging to the technical field of connectors. Background Art

[0002] In the prior art, for example, the invention with application number 202310873399.3 discloses an integrated structure of a plastic shell of a power supply and a terminal block. In order to solve the problem that the shell structure of the terminal block is usually formed by molding, the plastic shell of the power supply and the plastic shell of the terminal block are formed by independent molding, which makes the terminal block larger in size, loosely fits with the power supply shell and occupies a larger space, making it impossible to miniaturize the power supply shell design, and unable to achieve the sealing between the terminal block and the power supply shell, and increasing the product cost and reducing the reliability of the product. The power supply shell and the terminal block are designed as an integrated whole with a compact structure and reasonable design, which improves assembly efficiency and reduces production costs. At the same time, the sealing of the power supply shell and the terminal block is improved, with high reliability and easy promotion and use.

[0003] Similar to the above application, there are still some shortcomings:

[0004] During the insertion of the wire, it is necessary to first insert it through the threading hole on the side of the housing, and then insert it into the terminal. The plug-in condition of the wire and the terminal cannot be observed, which affects the effect of wire installation. In addition, the protective cover on the housing adopts a plug-in installation method, and is separated from the housing. It is not only inconvenient to assemble, but also easy to cause the loss of accessories, which is inconvenient to use.

[0005] Therefore, a power supply housing and wiring terminal integrated structure is designed to optimize the above-mentioned problem. Utility Model Content

In addition, the arc-shaped wire groove opened at the bottom of the opening is used in conjunction with the arc-shaped bayonet on the L-shaped card plate. At the same time, the torsion spring is used to control the resetting of the L-shaped card plate, so that the positioning of the wiring terminal is more convenient. The L-shaped card plate is integrally arranged with the power supply housing to avoid the loss of accessories and ensure the protection effect of the terminals. By arranging a clamping mechanism composed of a slide groove, a pressure plate and an extrusion spring on the top of the arc-shaped bayonet, the pressure plate can be used to clamp the connecting wire after the L-shaped card plate is reset, so that the stability of the connecting wire is higher.
