Plugging-and-clamping-type triode fixing device

Abstract

The invention discloses a plugging-and-clamping-type triode fixing device. The left side of the substrate plate is provided with a fixed through hole. The top face at the middle part of the base plate is fixedly provided with an upper connection block. The middle part at the bottom face of the upper connection block is provided with a plugging groove. The right end of the plugging groove is located at the right end face of the upper connection block. The bottom face of the upper connection block is fixedly arranged at the top face of the base plate. The top face of the plugging concave and all the inner side walls are all fixedly provided with elastic sheets. The top face of the bottom plate right under the plugging groove is fixedly provided with lower elastic sheets. The elastic sheets at the top face of the plugging groove and the lower elastic sheets are all provided with a plurality of positioning and inserting holes with the upper ones corresponding to the lower ones. A plurality of spherical stunt pistons are inserted into the positioning screw holes on the top face of the plugging groove and the top face of the bottom plate through screw threads. According to the invention, a triode is inserted into a plugging groove, and through the positioning of the spherical stunt pistons and the fastening of the positioning screw bolts, the triode can be well fastened and can withstand shocks well. In addition, the triode can be detached and replaced separately, rather than the replacement as a whole, therefore, saving the cost.

Description

[0001] Technical field: [0002] The invention relates to the technical field of elevator equipment, and more specifically relates to a plug-in clamping type triode fixing device. [0003] Background technique: [0004] The triode is a semiconductor device that controls the current by current. The current method is generally to package it on the connection board by injection molding, and fix the connection board to the circuit board or other electrical components by bolts. Since the triode and the connection board are integrated in practical applications It is wasteful to assemble and take it as a whole, and it is troublesome to replace, and the connecting plate needs to be removed. Therefore, in a triode fixing device disclosed in the Chinese invention patent No. 201420599514.9, the triode is fixed by clamping and fixing, which is convenient for loading and unloading, and the replacement only needs to replace the triode without the need for complete assembly, saving costs.

[0004] The triode is a semiconductor device that controls the current by current. The current method is generally to package it on the connection board by injection molding, and fix the connection board to the circuit board or other electrical components by bolts. Since the triode and the connection board are integrated in practical applications It is wasteful to install and remove, and it is troublesome to replace, and the connecting plate needs to be removed

Therefore, in a triode fixing device disclosed in the Chinese invention patent No. 201420599514.9, the triode is fixed by clamping and fixing, which is convenient for loading and unloading, and the replacement only needs to replace the triode, without the need for complete assembly, saving costs. However, its clamping effect is limited. When the connection is strongly shaken, it is easy to slip and the anti-seismic effect is limited.
