Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall fall within the protection scope of the present invention.

As shown in fig. 2, the utility model relates to a waterproof Type C connector of silica gel mode comprises outside iron-clad 2, inside iron-clad 1, outer silica gel circle 6, interior silica gel circle 8, post forming plastic part 7.

The riveting position of the inner iron shell 1 is welded by the inner iron shell 1 in a welding mode to form a welded inner iron shell 3, and the length of the welded inner iron shell 3 is greater than that of the outer iron shell 2. The length of the outer iron shell 2 is 1/3 the length of the welded inner iron shell 3. And assembling the inner and outer iron shells to form the welded inner and outer iron shells 5 by welding the welded inner iron shell 3 and the outer iron shell 2. Because the length of the welded inner iron shell 3 is greater than the length of the outer iron shell 2, the welded inner iron shell 3 extends out of the outer iron shell 2, i.e. the end of the welded inner and outer iron shells 5 is a concave 501.

The one-shot shaped element 4 is assembled with plastic to form a two-shot shaped plastic part 7. The outer surface of the secondary forming plastic part 7 is provided with a joint part 701 for placing the inner silica gel ring 8, and the joint part 701 can be in a groove shape or a convex ring surface structure. The size and shape of the attaching part 701 are matched with those of the inner silicone ring 8. After the inner silica gel ring 8 is sleeved on the periphery of the secondary forming plastic part 7, the inner silica gel ring 8 is inserted into the inner and outer welded iron shells 5 to realize assembly, and the inner silica gel ring 8 can realize the waterproof function between the inner and outer welded iron shells 5 and the secondary forming plastic part 7. Preferably, the inner silicone ring 8 is an elliptical ring structure.

The outer silicone ring 6 includes an outer end elliptical ring portion 601 and an inner end elliptical ring portion 602. The outer end oval ring portion 601 is sleeved on the end portion of the inner end oval ring portion 602, and the height of the outer end oval ring portion 601 is higher than that of the inner end oval ring portion 602, and the width of the outer end oval ring portion is smaller than that of the inner end oval ring portion 602.
