Description

Technical Field

[0001] The utility model relates to the technical field of structural application in the machinery industry, in particular to a flexible wiring structure for electrical products. Background Art

[0002] When the cage-type terminals of existing panel switches and socket products are placed in the bottom shell, there is a large gap between the cage-type terminals and the cage-type terminals installation slot in the bottom shell due to the requirement of easy assembly. And when the panel frame that is buckled with the bottom shell is buckled with the bottom shell, due to the requirements of structural design, the panel frame generally does not contact the cage-type terminals. Therefore, when shaking such products, the cage-type terminals and the crimping screws screwed into them will shake, making a loud noise, which often gives customers a bad impression of the product.

[0003] The crimping screws screwed into the terminals of existing panel switches and socket products often rotate and fall out of the terminals due to vibration during long-term transportation. In order to prevent such incidents from happening, the industry often uses a solution to make a notch on the screw to cause thread deformation, so that the screw and the thread of the terminal form a jam, so as to prevent the screw from rotating due to vibration, thereby preventing the screw from falling out of the terminal. However, this solution is difficult to control in terms of production technology. When the notch is too large, the thread deformation is too large, resulting in excessive torque when the screw is screwed into the cage terminal. When the notch is too small, the thread deformation can be ignored, and the screw and the cage terminal thread cannot form a jam, and the design function is lost. At the same time, automatic assembly is becoming more and more popular. During the automatic assembly process, a large number of thread jams occur in crimping screws with notched threads and cage terminals, resulting in a high rate of automatic assembly defects. Utility Model Content

[0004] In view of the above technical problems, the utility model solves the problems of large shaking degree of cage-type terminal blocks in the prior art, difficult control of the production process of crimping screws, and difficulty in adapting to automated assembly, and provides a simple and reliable flexible wiring structure.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: a flexible wiring structure for electrical products, including a junction box, the junction box is composed of a bottom shell and a panel frame that are interlocked, the junction box is provided with a wiring terminal, the wiring terminal includes a cage-type wiring cavity and a wire-pressing screw passing through the upper end of the cage-type wiring cavity, the panel frame is provided with a positioning groove for accommodating the cage-type wiring cavity and a limiting groove for preventing the wire-pressing screw from slipping out and shaking, the bottom shell is provided with a pressure cavity corresponding to the positioning groove and a flexible filling structure corresponding to the limiting groove.

[0006] In the above-mentioned flexible wiring structure for electrical products, the flexible filling structure is a longitudinal arch bridge-shaped thin sheet bone arranged on the bottom shell.

[0007] Alternatively: the flexible filling structure is a transverse plastic sheet arranged on the bottom shell, and the transverse plastic sheet is 3 sheets that are parallel to each other and spaced apart.

[0008] Alternatively, the flexible filling structure is a plastic column arranged on the bottom shell, and the column is a round column or a square column.

[0009] Compared with the prior art, the above-mentioned flexible wiring structure for electrical products includes a junction box, which is composed of a bottom shell and a panel frame that are interlocked with each other. The junction box is provided with wiring terminals, which include a cage-type wiring cavity and a wire-pressing screw that passes through the upper end of the cage-type wiring cavity. The panel frame is provided with a positioning groove for accommodating the cage-type wiring cavity and a limit groove for preventing the wire-pressing screw from sliding out and shaking. The bottom shell is provided with a pressure cavity corresponding to the positioning groove and a flexible filling structure corresponding to the limit groove. The structure of the utility model eliminates the sound generated by the cage-type wiring terminal and the wire-pressing screw when the product is shaken, and can prevent the wire-pressing screw from rotating due to long-term transportation vibration, which may cause it to fall out of the cage-type terminal, thereby preventing the wiring terminal from shaking and being damaged. The flexible wiring structure product of the utility model is more in line with the humanized design requirements of modern electronic products, ensuring that electrical products are easier and more reliable during transportation.
