Iron casing parcel structure about adopting can improve outer iron casing 4 greatly and to the holistic structurality of connector to the parcel restriction effort of drawing casing 3 and plastic body 2.

The plastic body 2 is of a two-section structure, a gap glue accommodating groove 23 is formed in the middle, and the gap glue accommodating groove 23 is filled with a waterproof filling glue 5. The terminal assembly 1 penetrates through the interval glue containing groove 23 to form gaps which are arranged in an interval staggered mode and are communicated up and down, and the waterproof filling glue 5 can seal the periphery of the terminal assembly 1.

Connect the upper surface or the lower surface of block portion 22 and be provided with and hold the sunken recess 221 that glues ditch 23 intercommunication with the interval, sunken recess 221 encloses with outer iron-clad 4 and keeps off and be formed with and hold gluey space, it can form the point mouth of gluing to hold gluey space, and forms some gluey air vents. The sunken groove 221 can be filled with waterproof filling colloid 5 according to requirements.

The cross section of the waterproof packing colloid 5 extends downward from the top inner wall surface of the inner shell 31 to the bottom inner wall surface of the inner shell 31, and then extends horizontally rearward to the front end face of the connection stopper 22. When the sunken groove 221 is filled with the waterproof filling colloid 5, the waterproof filling colloid 5 horizontally extends backwards to the rear end face of the connecting blocking portion 22, and vertically extends downwards to the surface of the inner wall of the bottom of the outer iron shell 4, so that a top-down fully-sealed partition type waterproof wall is formed on the cross section, the effect of separating the plug space 6 from the tail portion of the terminal assembly 1 is achieved, the plug space 6 is effectively placed, water enters the rear main board after entering the plug space, and the waterproof effect is achieved.

The front end of the tongue piece portion 21 protrudes from the front end surface of the drawer housing 3.

The outer peripheral baffle of the plugging space 6 is mainly formed by the drawing shell 3, and an effective sealing waterproof structure is formed by the integral structure of the drawing shell 3, so that the waterproof effect and the waterproof grade are greatly improved; combine waterproof packing colloid 5's structural design, seal the packing to the gap between draw casing 3 and the plastic main part 2, further improvement water-proof effects.

The manufacturing process of the high-strength ultrashort type-C connector female seat 100 with the clip-shaped drawing iron shell comprises the following steps:

1) the terminal assembly 1 is formed into a plastic body 2 through insert molding to obtain a terminal plastic assembly;

2) UV glue is dotted on the upper iron shell 41 and the lower iron shell 42, and then the UV glue and the drawing shell 3 are spot-welded together to form an iron shell assembly;

3) assembling the iron shell component and the terminal plastic component together;

4) taking the glue containing space as a glue dispensing opening, dispensing and filling the spaced glue containing grooves 23 to form waterproof filling glue bodies 5, and then baking and curing;

5) and packaging and blanking after performance detection.

In the female seat 100 of the high-strength ultrashort type-C connector of the clip-type drawing iron shell type, the clip-type drawing shell is arranged, and the inner shell in the inner and outer shell structure is used for wrapping the periphery of the rear section of the tongue piece, so that the overall strength of the tongue piece part is greatly enhanced; except the necessary length design of the tongue piece part, the length of the connecting blocking part of the plastic main body can be greatly shortened because the strength and the waterproof requirements are met, thereby realizing the short and small design of the whole length of the connector; the glue dispensing process is utilized to form the waterproof colloid, and the waterproof grade is greatly improved by matching with the clip-shaped drawing shell.

What has been described 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.
