Embodiment

The execution mode of water-proof connector of the present utility model is described by means of specific instantiation below, and ability office those of ordinary skill the content described in this specification can understand other advantages of the present utility model and effect easily.The utility model also can be implemented by means of other different instantiations or be applied, and the every details in this specification also based on different viewpoints and application, can carry out various amendment and change under not departing from spirit of the present utility model.Accompanying drawing of the present utility model is only simple declaration again, not describes according to actual size, that is unreacted goes out be correlated with the actual size of formation, hereby states.Following execution mode further describes viewpoint of the present utility model, but not to limit the utility model claims anyways.

See also Fig. 1 and Fig. 2, it is the pedestal of water-proof connector of the present utility model and the schematic diagram of housing.The water-proof connector 1 that the utility model is contained, can be preferably the connector of a USB (Universal Serial Bus, USB), such as, can be Micro USB or Mini USB etc., but not as limit.As shown in the figure, water-proof connector 1 includes pedestal 10 and a housing 20.The side of pedestal 10 is formed with two spaced convex walls 11 to outer one protrusion direction L.Be provided with a weld part 12 between two convex walls 11, and the opposite side of pedestal 10 outwards protrudes out and is formed with a portion of terminal 13; Water-proof connector 1 is welded on circuit substrate by weld part 12 thus, and by portion of terminal 13 and the mutual grafting of another electric connector, to be mutually electrically connected.In practical application, pedestal 10 can be preferably isolation material.

Specifically, portion of terminal 13 includes a tongue piece 131, and tongue piece 131 is provided with multiple spaced metallic circuit 132, and the other end of metallic circuit 132 described in these exposes to this weld part 12 between two convex walls 11.In actual applications, the number of metallic circuit 132 is designed according to demand, is not limited to shown in figure.It is worth mentioning that, weld part 12, in the length of protrusion direction L, is preferably and is less than two convex walls 11 in the length of protrusion direction L.

Housing 20 is around formation one grafting space S, and the two ends of housing 20 are defined as Single port 201 and a connector 202 respectively.Pedestal 10 is arranged in grafting space S, and is fixedly installed on port 201, and two convex walls 11 of pedestal 10 and weld part 12 are stretched on outside grafting space S, and the portion of terminal 13 of pedestal 10 is positioned at grafting space S.Wherein, the two side that the port 201 of housing 20 is relative stretches out and is formed with two keepers 21.Specifically, two keepers 21 can be inverted L shapes, and are stretched out by the port 201 of housing 20 and formed.Special instruction, the setting position of the keeper 21 of housing 20, can be designed according to demand, be not limited to content shown in the drawings, right and wrong can also be stretched out by port 201 and formed, but by two of housing 20 relative sidewalls, formed directly to downward-extension.In addition, in reality is implemented, housing 20 can be metal material.

Refer to Fig. 3, two the first sealing units 30 are arranged between two convex walls 11 and two keepers 21, with the gap of part between sealing base 10 and housing 20.In other examples, two keepers 21 are in this way by two of housing 20 relative sidewalls, and formed directly to downward-extension, two the first sealing units 30 can be arranged at two convex walls 11 lateral surface 111 not relative each other.First sealing unit 30 can be solidified by marine glue to be formed, and preferably the lateral surface of two the first sealing units 30 flushes with the lateral surface of the lateral surface of housing 20 and convex wall 11.
