That is to say, the shell 2 can be disassembled and assembled with the shell end cover 13 and the connecting end cover 1 respectively. The whole is a combined structure, which is convenient for subsequent disassembly and maintenance.

The shell 2 has a first accommodating cavity, the shell cover 13 covers the first accommodating cavity, a first circuit board 11 is arranged in the first accommodating cavity, and a first connecting member is arranged on the first circuit board 11. That is to say, the shell 2 is a shell with a cavity structure, and the shell cover 13 covers the first accommodating cavity to close the first accommodating cavity. The first circuit board arranged in the accommodating cavity inside the shell 2 is an integrated circuit board, and the first connecting member arranged on the first circuit board serves as a connecting terminal for signal transmission.

The connecting end cover 1 has a second accommodating cavity, a second circuit board 7 is arranged in the second accommodating cavity, a second connecting piece is arranged on the second circuit board 7, the shell 2 covers the second accommodating cavity, and the first connecting piece and the second connecting piece are connected. That is to say, the connecting end cover 1 is placed on the shell 2, and the shell 2 can cover the second accommodating cavity to achieve the closure of the second accommodating cavity. When the connecting end cover 1 is placed on the shell 2, the first connecting piece is inserted into the second connecting piece to achieve conduction between the first circuit board and the second circuit board to realize signal transmission.

The above-mentioned connecting end cover, shell and shell cover plate are a combined structure as a whole, which can be quickly assembled. During maintenance, only the shell or the connecting end cover needs to be replaced. The first connecting part on the shell can be used after being connected to the second connecting part on the connecting end cover, and the undamaged part can continue to be used, which saves costs and solves the problem that the current integrated solenoid valve driver is difficult to repair and easily causes damage to other components during maintenance.

Further, the connection end cover 1 is detachably connected to the upper part of the shell 2 by a first bolt, and the shell end cover 13 is detachably connected to the lower part of the shell 2 by a second bolt, that is, the connection end cover 13 and the shell 2 are both provided with screw holes corresponding to the first bolt, and the shell end cover 13 and the shell 2 are both provided with screw holes corresponding to the second bolt, and the first bolt is used to thread the connection end cover 1 and the screw holes on the shell 2, thereby fixing the connection end cover 1 and the shell 2, and the second bolt is used to thread the shell end cover 13 and the screw holes on the shell 2, thereby fixing the shell end cover 1 and the shell 2, and when the connection end cover 1 or the shell 2 needs to be replaced, only the first bolt needs to be removed to replace a new connection end cover or a new shell, and when damage occurs in the shell 2, the second bolt can also be removed to replace or repair the components of the shell 2. It should be noted that the connection end cover 1 can also be set on the front, side or back of the shell, etc., and is not limited to being installed on the upper part of the shell, and the shell end cover 13 is also not limited to being installed on the lower part of the shell 2.
