Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, a waterproof button switch comprises a cylindrical switch base 1, wherein a key 2 is arranged at the upper end of the switch base 1 in a sliding manner along the vertical direction, and the axis of the key 2 is overlapped with the axis of the switch base 1. Three pins 3 which are used for being in plug-in fit with the connector are installed in the switch base 1, and the pins 3 penetrate out of the bottom of the switch base 1.

As shown in fig. 1 and 2, a waterproof sleeve 4 for protecting the pin 3 from water is fitted over the lower end of the switch base 1, and a vertically through cavity 5 is formed inside the waterproof sleeve 4. The waterproof external member 4 is sequentially provided with a clamping end 6, a binding end 7 and a contraction end 8 positioned at the bottom from top to bottom. Circumferential direction has the sand grip 9 towards the lateral wall of switch seat 1 outer lane on the 6 inside walls of joint end, and sand grip 9 sets up along the horizontal direction. The lower end of the switch base 1 is inserted into the clamping end 6, and the raised strip 9 and the outer side wall of the switch base 1 are abutted tightly.

As shown in fig. 1 and 3, the inner diameter of the fastening end 6 is larger than the inner diameter of the binding end 7, and a circumferential surrounding wrapping edge 10 is integrally formed on the outer side wall of the upper end of the fastening end 6. The joint of the clamping end 6 and the binding end 7 is formed with an inclined surface 17 inclined towards the axial lead direction of the binding end 7. The inner side wall of the bound end 7 is relatively smooth, and the bound end 7 is in the shape of a sleeve with an inner diameter which is equal everywhere.

As shown in fig. 1 and 3, three corrugated convex edges 11 are formed on the contraction end 8 along the vertical direction, and the maximum diameter of the three convex edges 11 is gradually reduced downwards. The inner side wall of the convex edge 11 is provided with three pressing strips 12 which are evenly distributed at intervals, and the inner diameter of each pressing strip 12 is gradually reduced downwards. The lower end of the contraction end 8 is fixedly connected with a tubular wire inlet sleeve 13, and the axial lead of the wire inlet sleeve 13 is overlapped with the axial lead of the contraction end 8. The inlet wire cover 13 has certain hardness, is difficult for taking place deformation, and when the connecting wire penetrated in the inlet wire cover 13, the inlet wire cover 13 can be with the connecting wire chucking to can prevent that the connecting wire from taking place to slide, make more firm of connecting wire.

As shown in fig. 1 and 4, a circumferentially surrounding limiting groove 16 is formed in the switch base 1, a sealing sleeve 14 is fixed in the limiting groove 16 in a limiting manner, and the axis of the sealing sleeve 14 overlaps with the axis of the switch base 1. The lower end edge of the sealing sleeve 14 is inserted into and pressed against the limiting groove 16. The middle part of the sealing sleeve 14 is provided with a through hole, and the lower end of the key 2 is inserted into the middle part of the sealing sleeve 14 through the through hole. The lower end of the key 2 is formed with a ring groove 15 (see fig. 5) facing the sealing sleeve 14, and the middle part of the sealing sleeve 14 is clamped in the ring groove 15 (see fig. 5).

The specific effects of the embodiment are as follows:

when the switch base 1 is installed on the connector, the connector is firstly placed in the cavity 5 of the waterproof sleeve 4, and then the connecting wire of the connector is led out from the wire inlet sleeve 13 at the lower end of the contraction end 8. And then, inserting the pin 3 at the lower end of the switch base 1 into the upper end of the connector, after the two are fixed, moving the waterproof sleeve 4 towards the direction close to the switch base 1, and enabling the clamping end 6 to be sleeved in from the lower end of the switch base 1. The sand grip 9 that sets up on 6 inside walls of joint end can compress tightly each other with the lateral wall of switch seat 1 to can tightly overlap 4 waterproof external members at 1 lower extreme of switch seat. At this moment, the joint of the pin 3 and the connector is located in the binding end 7, and the inner side wall of the binding end 7 is tightly attached to the outer side wall of the connector, so that the sealing effect of the joint can be enhanced. The corrugated convex edge 11 formed on the contraction end 8 enhances the flexibility of the contraction end 8, and because the maximum diameter of the convex edge 11 is gradually reduced downwards, when the connector is subjected to outward tension of a connecting line, the convex edge 11 can not only firmly constrain the connector in the waterproof sleeve 4, but also the wire inlet sleeve 13 at the lower end of the contraction end 8 can limit and fix the connecting line of the connector, so that the conditions of looseness and fracture between the connecting line and the connector are avoided; the anti-drop protection between the connecting line and the connector is enhanced.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
