[0003] Patent publication number CN116315832A in the prior art discloses a waterproof Type-C connector and a manufacturing method thereof, which includes a metal shell, wherein the metal shell includes an upper iron shell and a lower iron shell, the upper iron shell and the lower iron shell are welded together at the ear plate to cover the plastic terminal assembly, and then the upper iron shell and the draw-out shell on the plastic terminal assembly are welded together, and the stop point of the entire metal shell in the plug-in direction is achieved by the bending buckle point at the tail of the metal shell. When the tail buckle point of the metal shell is bent, sometimes the point marking is unstable, the bending buckle is broken, or the point marking of the stop point is missed, which leads to unstable stop position.

[0004] Therefore, it is necessary to provide a new TYPE-C connector with high structural strength to solve the above technical problems. [Contents of the utility model]

[0007] Furthermore, the C-shaped covering portion and the back surface covering portion are seamlessly connected at the adjacent portion to form a C-shaped transition arc surface.

[0008] Furthermore, the extraction shell is an integrated structure formed by extraction of a thin-walled cylindrical structure, and includes an inner cylinder, an outer cylinder, and a connecting portion connecting the inner cylinder and the outer cylinder at the tail end; the back side of the connecting portion abuts against the front end face of the convex ring portion to achieve stopping.

[0009] Furthermore, the inner cylinder is wrapped around the outer periphery of the tail section of the tongue portion, and a glue filling cavity is formed around the inner cylinder and the convex ring portion, and a waterproof glue block is formed in the glue filling cavity by glue dispensing.

[0010] Furthermore, it also includes a withdrawal ring and a waterproof rubber ring; the withdrawal ring is fixed around the front end periphery of the withdrawal shell, and the waterproof rubber ring is sleeved on the front end periphery of the withdrawal shell and the back is against the withdrawal ring to stop.

[0011] Furthermore, the withdrawal ring includes a covering portion that embraces the outer peripheral surface of the withdrawal shell and a blocking portion that extends radially outward from the front end edge of the covering portion; the covering portion is spot-welded to the outer peripheral surface of the withdrawal shell; and the back of the waterproof rubber ring relies on the blocking portion to achieve axial limitation.

[0012] Furthermore, both left and right sides of the upper iron shell and the lower iron shell extend outward horizontally to form ear plates, and the upper and lower surfaces of the ear plates of the upper iron shell and the lower iron shell are attached to each other and fixed together by spot welding.

[0013] Furthermore, the C-shaped covering portion is fixedly connected to the upper surface of the drawer shell by spot welding; and the lower iron shell is fixedly connected to the lower surface of the drawer shell by spot welding.

[0014] Furthermore, a snap-on stop plate is riveted on the rear side of the lower iron shell to form a stopper with the back of the convex ring portion.

[0015] The beneficial effect of the TYPE-C connector with high structural strength of the utility model is that: by arranging a draw-out shell to cover the outer periphery of the plastic terminal assembly, and then arranging an outer iron shell on the outer periphery of the draw-out shell by spot welding, the draw-out shell and the outer iron shell together constitute the metal shell structure of the connector, which greatly improves the structural strength of the connector as a whole; in addition, in the outer iron shell, a draw-out process, a bending process and a side cutting process are combined to form an upper iron shell, and the above process forms a C-shaped covering portion and a back covering portion in the upper iron shell, and the back covering portion is used to cling to the back of the plastic terminal assembly to form a blocking structure in the plug-in direction for the back of the plastic terminal assembly, which greatly improves the overall stop-retract ability of the connector in the plug-in direction, and effectively solves the problem of unstable stop-retract function caused by breakage of the stop-retract buckle, missing rivet points of the stop-retract buckle, or insufficient riveting of the stop-retract buckle in the original buckle point stop-retract structure.

[0026] The present embodiment adopts the drawing process, the bending forming process and the side cutting process to form the upper iron shell 4, so that the upper iron shell 4 is an integral structure and the C-shaped covering part 41 and the back covering part 42 are seamlessly connected at the adjacent part to form a C-shaped transition arc surface 43. Since the back covering part 42 and the C-shaped covering part 41 are an integral structure, the back covering part 42 is used to form a stop-retract blocking structure for the plastic terminal assembly 1 in the plug-in direction, thereby improving the stop-retract ability of the connector in the plug-in direction, and effectively solving the problem of unstable stop-retract function in the original buckle point stop-retract structure due to the breakage of the stop-retract buckle, the missing of the stop-retract buckle riveting point, or the failure of the stop-retract buckle to be riveted in place.

[0027] The draw-out shell 2 is an integrated structure formed by drawing a thin-walled cylindrical structure, and includes an inner cylinder 21, an outer cylinder 22, and a connecting portion 23 connecting the inner cylinder 21 and the outer cylinder 22 at the tail end. The inner cylinder 21 is wrapped around the outer periphery of the tail section of the tongue portion 11, and a glue filling cavity (not shown in the figure) is formed between the inner cylinder 21 and the convex ring portion 12, and the waterproof glue block 7 is formed in the glue filling cavity by dispensing glue. The back of the connecting portion 23 abuts against the front end surface of the convex ring portion 12 to achieve a stop.

[0028] The draw ring 3 is fixed to the outer periphery of the front end of the draw shell 2; the waterproof rubber ring 6 is sleeved on the outer periphery of the front end of the draw shell 2 and the back of the waterproof rubber ring 6 is stopped by the draw ring 3. The draw ring 3 includes a covering portion 31 that surrounds the outer peripheral surface of the draw shell 2 and a blocking portion 32 that extends radially outward from the front edge of the covering portion 31. The covering portion 31 is spot-welded to the outer peripheral surface of the draw shell 2. The back of the waterproof rubber ring 6 is against the blocking portion 32 to achieve axial limit.

[0029] The left and right sides of the upper iron shell 4 and the lower iron shell 5 are horizontally extended outward to form ear plates 51. The main bodies of the upper iron shell 4 and the lower iron shell 5 are enclosed to form a covering ring structure that covers the outer peripheral surface of the rear section of the drawer shell 2 and the outer peripheral surface of the convex ring portion 12. The upper and lower surfaces of the ear plates 51 of the upper iron shell 4 and the lower iron shell 5 are attached to each other and fixedly connected together by spot welding. The ear plates 51 are provided with mounting holes 52 to facilitate fixing the connector as a whole on the main board.

[0030] The C-shaped covering portion 41 covers the upper surface of the rear section of the drawer housing 2 and the upper surface of the convex ring portion 12, as well as the left and right side areas of the rear section of the drawer housing 2 and the left and right side areas of the convex ring portion 12. The C-shaped covering portion 41 is fixedly connected to the upper surface of the drawer housing 2 by spot welding.

[0031] The lower iron shell 5 is fixedly connected to the lower surface of the drawer shell 2 by spot welding, and a buckle stopper 53 is riveted on the rear side thereof to form a stopper with the back of the convex ring portion 12 .

[0032] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
