Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

As shown in fig. 1 to 3, the utility model discloses a waterproof switch casing structure, including PCB mainboard 1, drain pan 2, panel, signal pencil subassembly 3, PCB mainboard 1 is connected inside drain pan 2, and panel sealing connection is in the outside of drain pan 2, is equipped with pencil hole 51 on a side panel of drain pan 2, and signal pencil subassembly 3's plug is connected with a signal seat on PCB mainboard 1 after passing pencil hole 51, and signal pencil subassembly 3 is connected with a side panel sealing connection of drain pan 2. The panel connected with the bottom shell 2, the signal wire harness assembly 3 and other components are connected by adopting a sealing structure, so that the whole shell has a waterproof effect from the outside and has a protection effect on the internal PCB mainboard 1.

Waterproof switch shell structure still includes sealing washer 7, and the panel includes upper cover plate 4, rear panel 6, front panel 5, and the top of drain pan 2 is equipped with the seal groove, and in sealing washer 7 embedding seal groove, upper cover plate 4 covers on drain pan 2 top and passes through the fastener and connect. The rear end of the bottom shell 2 is provided with a sealing groove, a sealing ring 7 is embedded in the sealing groove, and the rear panel 6 covers the rear part of the bottom shell 2 and is connected with the rear panel through a fastener. The front end of drain pan 2 is equipped with the seal groove, and in sealing washer 7 embedding seal groove, front panel 5 covered in drain pan 2 anterior and connected through the fastener. The sealing ring 7 is preferably a rubber ring. The connecting gaps between the upper cover plate 4, the rear panel 6, the front panel 5 and the bottom shell 2 are all provided with sealing rings 7, so that the whole machine shell is made to be a place where water leakage possibly occurs from the external sealing position, and the interior of the machine shell is further ensured to be a sealed and waterproof space.

The signal harness assembly 3 comprises a signal harness 31, a threaded joint 32, a fastening nut 33 and a sealing ring 7, wherein the threaded joint 32 is connected to the signal harness 31, a harness hole 51 is formed in the front panel 5, a sealing groove is formed in the harness hole 51 of the front panel 5, one side of the threaded joint 32 is clamped in the sealing groove through the sealing ring 7, and the other side of the threaded joint 32 penetrates through the harness hole 51 and then is connected with the fastening nut 33.
