Side dial switch improved structure

Abstract

The invention relates to a side dial switch improved structure, belonging to field of electric appliance switch devices. A side dial switch of the invention is mainly formed by a seat body, a terminal group and a cover body. Terminals in pre-formed shapes are fixed on the seat body in an assembly or integrated forming mode. The shape of the terminal group is a shape that a connection section extends outwards from two corresponding side walls of the seat body respectively and is bended to be 90-degree angles toward a direction away from the seat body, and the terminals can accurately and stably reach welding positions through processing and bending. A switch in the form of DIP and SMT can be manufactured by using the same terminal parts. According to the design, the terminal formation is more accurate, and the purposes of reducing development cost and production cost are achieved through sharing parts.

Description

technical field [0001] The invention belongs to the field of electrical switch devices, and relates to a key switch, especially the structure of a side dial switch. Background technique [0002] At present, the general side dial switch includes side dial switch with lamp body and side dial switch without lamp body, please refer to figure 1 As shown, it is a structural schematic diagram of a known side dial switch. The side dial switch 1 is mainly composed of a base 10, an LED light-emitting element 11, a conductive shrapnel 12, a cover 14, a first terminal 16, a second terminal 17 and a plurality of LED terminals 18, and the base 10 is combined with the aforementioned first terminals 16, second Terminal 17 and LED terminal 18, and each first terminal 16, second terminal 17 and LED terminal 18 extend backward from the top of the base 10, and are bent downward for welding on the circuit board 2, wherein each plurality of LED The terminal 18 is connected to the LED light-emit...

AI Technical Summary

Problems solved by technology

In other words, the aforementioned method of extending the first terminal 16, the second terminal 17, and the LED terminal 18 from the top of the base 10 to the rear, and bending downwards for soldering on the circuit board 2 may easily lead to failure after soldering. Only the first terminal 16 and the second terminal 17 on a single side can bear the supporting force of external pressing force, especially the second terminal 17 is the outermost and longest terminal, so long-term pressing or pressing force is too large It is very easy to cause the first terminal 16 to bend and deform while the deformation of the second terminal 17 will be relatively serious.

In addition to the aforementioned problems, due to the long lengths of the first terminal 16, the second terminal 17 and the LED terminal 18, it is easy to cause the problem of difficult positioning during re-soldering

[0003] In view of the aforementioned structural problems, in order to strengthen the terminals 16 in welding and use to avoid damage caused by long-term use and pressing, and in order to effectively fix the first terminal 16, the second terminal 17 and the LED terminal 18 In order to facilitate soldering on the corresponding welding points on the circuit board 2, a fixed block 19 is jointly installed on the first terminal 16, the second terminal 17 and the LED terminal 18, and the fixed block 19 is used to form multiple and welded joints. point corresponding to the perforation 190, so each terminal 16 means that the distance between the first terminal 16, the second terminal 17 and the LED terminal 18 is determined after passing through the perforation 190, so that it is not easy to misplace the feet during welding. Lead to poor quality and other problems, while strengthening the strength of the first terminal 16, the second terminal 17 and the LED terminal 18 welded on the circuit board 2, and effectively reducing the bending deformation of each terminal 16 due to long-term pressing or excessive pressing force However, when the first terminal 16, the second terminal 17 and the LED terminal 18 are put through the fixing block 19, the overall process must be increased, which not only takes time but also increases the overall cost. In addition, the manufacturing process is relatively complicated and the cost is high. Deformable feet
