[ detailed description ] A

The first embodiment is as follows:

referring to fig. 1 to 3, the present embodiment is a waterproof Type-C connector 100, which includes a tongue main body 1, an MIM iron shell 2 covering the periphery of the tongue main body 1, and a waterproof silicone ring 3 covering the periphery of the end of the MIM iron shell 2, wherein steel sheets 4 are assembled on the upper and lower surfaces of the tongue main body 1, the steel sheets 4 are assembled with the tongue main body 1 in a snap-fit manner, and the MIM iron shell 2 is connected to the steel sheets 4 by spot welding.

Waterproof silica gel circle 3 includes annular main body 31, is provided with two at least annular protruding muscle 32 on the annular main body 31, is formed with first annular groove 33 between two adjacent annular protruding muscle 32, and the groove depth of first annular groove 33 is greater than the height dimension of annular protruding muscle 32. The annular rib 32 is formed to protrude outward from the reference circumference of the annular main body 31, i.e., in the present embodiment, the groove bottom of the first annular groove 33 is recessed downward below the reference circumference of the annular main body 31. Design through the groove depth with first annular groove 33 and still will be big than annular protruding muscle 32, its main objective is when connector and equipment casing assemble, and annular protruding muscle 32 on the waterproof silica gel circle 3 has bigger deformation space, has reduced the equipment degree of difficulty when guaranteeing sealed effect, is convenient for realize fast assembly.

In this embodiment, a plurality of annular ribs 32 are adopted, so that a plurality of sealing rings can be formed, and the waterproof sealing effect is improved. The periphery of MIM iron shell 2 is provided with second annular groove 23, and waterproof silica gel circle 3 sets up in second annular groove 23, prescribes a limit to waterproof silica gel circle 3 through second annular groove 23 in the ascending position of axial, prevents that waterproof silica gel circle 3 from droing or shifting, loses sealed effect.

In this embodiment, the annular main body 31 is further formed with extension sections 34 near the front and rear ends, and the width of the extension sections 34 is 1-3 mm. The diameter of the outer peripheral surface of the extension section 34 is gradually reduced from inside to outside in the axial direction to form a slope structure, and the slope of the slope structure is 1 to 2 degrees. Through the design of extension section 34, can improve waterproof silica gel circle 3 compressive strength in the axial on the one hand, prevent to take place axial deformation with equipment casing assembling process, influence water-proof effects. In order to ensure the compressive strength of the waterproof silicone ring 3, the extension section 34 needs to have a certain width to resist the axial extrusion force. Through the design of inclined plane structure, when connector and equipment casing were assembled, can reduce the interference volume of waterproof silica gel circle 3 and equipment casing, reduce the equipment degree of difficulty, improve the packaging efficiency. The inclination of inclined plane structure should not be too big, if the inclination is too big, then cause the rubber ring material to be thick too thin easily at waterproof silica gel circle 3's tip, compressive capacity reduces, and when assembling with the equipment casing, forms oblique ascending and too big extrusion force easily to annular protruding muscle 32, causes annular main part 31 inner circle and 2 outer walls of MIM iron-clad to form the gap, has increaseed the interference volume of annular protruding muscle 32 with the equipment casing in addition, has improved the equipment degree of difficulty.

Through the shape structural design of the waterproof silicone rubber ring 3 in the embodiment, because the annular convex rib 32 has enough deformation space, the backward extrusion force of the equipment casing can be reduced, so that the axial assembly position stability of the waterproof silicone rubber ring 3 in the equipment casing can be improved, and the axial displacement can not occur due to the internal stress elastic recovery of the waterproof silicone rubber ring 3.

The left and right sides level of MIM iron shell 2 extends and is provided with connection otic placode 21, be provided with screw lock on the connection otic placode 21 and attach the hole 22.

The MIM iron shell 2 and the back of the tongue piece main body 1 surround to form a glue dispensing groove, and a waterproof glue block (not marked in the figure) is filled in the glue dispensing groove.

The above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
