Card holder, SD (Secure Digital) card holder, etc. In the specific embodiment, the connector 01 is taken as a USB socket as an example for reference. The connector 01 and the waterproof case 100 can be jointly applied to a mobile terminal, and the mobile terminal can be a mobile phone, a tablet computer or a notebook computer.

The inner side of the first open end 10 is smaller than the inner diameter R of the second open end 20, and the connector 01 is inserted into the waterproof case 100 through the second open end 20, the inclined inner side wall 30 The connector 01 is guided to facilitate the assembly of the connector 01 with the waterproof cover, reducing the assembly labor of the waterproof cover 100 and the connector 01, and effectively reducing the production cost.

Referring to FIG. 2 , in the embodiment, the connector 01 is exemplified by a USB socket. Specifically, the connector 01 includes a socket end 02 and a tail end 03 disposed opposite to the socket end 02. The socket end 02 is provided with a socket for inserting with an external connection plug. The tail end 03 is fixed with a plurality of conductive pins, a plurality of conductive pins extending to the inside of the socket, and a plurality of the conductive pins are connected to the main board through a conductive cable. Of course, in other embodiments, the connector 01 can also be a headphone jack, and the connector 01 can be provided with a conductive pin between the socket end 02 and the tail end 03.

In the present embodiment, the waterproof cover 100 has a sleeve shape. The first open end 10 and the second end 20 are sleeved on the circumferential side of the connector 01, and the first open end 10 is adjacent to the socket end 02 of the connector 01. The two open ends 20 are adjacent to the trailing end 03 of the connector 01.

Since the inner diameter of the second open end 20 just allows the spigot end 02 to pass, the slant is in the process of sliding the spigot end 02 from the second open end 20 toward the first open end 20 The inner side wall 30 is gradually closely attached to the circumferential side wall of the socket end 02, and finally the inclined inner side wall 30 seals the circumferential side of the connector 01, and the inner side of the second open end 20 seals the connector The trailing end 03 of 01. The inclined inner side wall is seamlessly wrapped around the circumferential side of the connector 01, and the first inner side wall 13 is fitted to the circumferential side of the connector 01. When the water is oozing out on the circumferential side of the connector 01, the inclined inner side wall 30 blocks the oozing water so that water cannot flow to the outside of the waterproof case 100, and enters from the spigot end 02 The water inside the connector 01 can only stay inside the connector 01 or ooze out between the waterproof sleeve 100 and the peripheral side wall of the connector 01, thereby achieving the circumference of the connector 01. Side waterproofing. Most importantly, the inner side of the second open end 20 seals the tail end 03 of the connector 01 such that water oozing from the peripheral side of the connector 01 cannot flow out through the second open end 20 The outside of the waterproof cover 100, that is, the oozing water, cannot damage the components outside the waterproof case 100.

Further, referring to FIG. 3 and FIG. 4 , the inside of the second open end 20 is circumferentially provided with a sealing waterproof rib 21 , and the sealing waterproof rib 21 abuts against the outer sidewall of the connector 01 .
