A clamping hole is opened on the bottom edge of one side of the transformer body 1 and the shell 3, and the buckle 9 fits in the clamping hole, so that the electronic module can be stably clamped in the transformer through the clamping structure composed of the clamping block 8, the buckle 9, the conical head 10 and the spring 11. The bottom edge of the shell 3 is connected to the spring 11 corresponding to the clamping block 8, and the end of the spring 11 is connected to the edge of the clamping block 8.

[0030] Working principle and use process of the utility model: In the actual application process of the electrical connection and disassembly mechanism of the outdoor electronic module, the shell 3 is first connected in an embedded manner in the cavity 2. The cavity 2 is a square body as a whole. The cavity 2 is closed on all sides. An opening is provided at the bottom for inserting the electronic module. A square hole is provided at the top to expose the gold finger socket 4, which is convenient for inserting and installing the electronic module. Then, a plug board 5 is welded on the top of the gold finger socket 4. The plug board 5 is located inside the transformer body 1 during use.

The electronic module is blocked by the buckle 9 and cannot be withdrawn, and the fixation is completed;

[0033] Finally, when the electronic module needs to be disassembled and replaced, the head thread of the operating rod 13 is screwed into the screw hole of the internal threaded cylinder 12 at the bottom of the electronic module. After tightening, the clamping block 8 is pushed inward and completely immersed in the shell 3, and the buckle 9 withdraws from the clamping hole. The operating rod 13 is pulled, and the electronic module withdraws from the cavity 2 and is taken out with the operating rod 13 because there is no obstruction from the buckle 9.
