Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, for the present invention provides a waterproof structure of a button, which is an outer surface, comprising a housing 1, wherein an embedding groove 11 is arranged in the housing 1, the embedding groove 11 is divided into a deep groove 113 and a shallow groove 114, in fig. 2, the length of the shallow groove 114 is greater than that of the deep groove 113, and the deep groove 113 is arranged in the middle of the shallow groove 114; the contact 2 and the key 3 are arranged in the caulking groove 11; the contact 2 is arranged on the deep groove 113, a cover plate 4 for limiting the moving range of the key 3 is also arranged on the outer surface of the shell 1, and a hole for allowing one end of the key 3 far away from the contact 2 to pass through is also arranged on the cover plate 4; the peripheral wall of the push button 3 is provided with a retaining plate 31 which is arranged between the bottom of the shallow groove 114 and the cover plate 4.

With reference to fig. 2, a waterproof layer 5 is provided between the key 3 and the contact 2 to provide waterproofing. The waterproof layer 5 comprises a waterproof board 51 and a spacer ring 52 which are made of silica gel, a ring groove 111 is arranged on the inner peripheral wall of the shallow groove 114, the edge end of the waterproof board 51 is arranged in the ring groove 111, and the caulking groove 11 is sealed, so that the difficulty of water entering the contact 2 from the end part of the waterproof board 51 can be increased; the spacer 52 is bonded to the side of the waterproof sheet 51 and is provided between the waterproof sheet 51 and the bottom of the shallow groove 114 in this embodiment, and the spacer 52 fills the space between the waterproof sheet 51 and the bottom of the shallow groove 114 and also supports the waterproof sheet 51 to absorb the load from the key 3.
