Description

  The present invention relates to a port plug of a mobile terminal, and more particularly to a waterproof plug of a mobile terminal.

  With the widespread use of electronic devices, mobile terminals are already indispensable in people's daily lives, and water is inadvertently used during use, and a series of inconveniences cannot be avoided.

  Accordingly, mobile terminal products having a waterproof function are being developed, and the number of such mobile terminals is increasing in the current sales market, and the demand for waterproof reliability and waterproof level is also increasing. For example, the invention disclosed in Patent No. CN10117609608 (invention name: mobile phone having a waterproof function with an I / O (Input / Output) connector) is such that one end of the plug is fixed and the other end is removable. The flexible glue part can be inserted into the case, and it has a tight fit with the wall on the hole opening side of the case to achieve waterproofing (side pressure waterproofing), but the flexible glue material is soft, so the strength and toughness are weak If the plug is pressed repeatedly, it will easily break, which will affect the waterproof performance of the device. According to the technical proposal, the case around the I / O (Input / Output) element must be enlarged to accommodate the flexible glue portion of the plug, while the process is limited by Since the outer peripheral surface is somewhat longer than the plug flexible glue, the area of the plug designed in this way is large.

  As another technical proposal, for example, a technical proposal disclosed in Patent No. CN2010042020 (invention name: waterproof device for an external target port of a portable mobile terminal) realizes a waterproof effect by tightening a plug with an auxiliary screw. According to the idea, the area of the plug must be increased and screwed, which affects the volume and shape of the mobile terminal and cannot meet the increasing demand for miniaturization.

  Accordingly, providing a waterproof plug that is small and can be retained in a small size that can retain the volume, beauty, and effective waterproof effect of a mobile terminal has become a problem to be solved by those skilled in the art.

  The technical problem to be solved by the present invention is that the area of the waterproof plug of the mobile terminal in the existing technology is large, and it is easy to protrude from the side surface due to the elasticity of the flexible glue, so as to eliminate defects such as a structure that is screwed. It is to provide a waterproof plug for a mobile terminal inserted vertically in a case.

  An embodiment of the present invention solves the above technical problem by the following technical solution: a plug for closing an opening on a case of a mobile terminal, a lid, a positioning link, a hole waterproof convex rib, The mobile phone terminal is provided with a positioning link provided outside the side wall of the lid body, and makes a round around the lid body. The waterproof waterproof rib is provided at a lower end of the lid body and extends downward. Provide a plug.

  The waterproof plug further includes: a columnar body vertically provided at a lower end of the lid body; and a columnar body waterproof convex rib provided on a side wall of the columnar body and surrounding the side wall of the columnar body. The body preferably extends downward along the vertical direction.

  The columnar body preferably further includes a columnar body positioning ring provided at one end of the columnar body away from the lid body.

  The waterproof plug is formed of plastic and flexible glue by two-stage molding, and the upper end surface of the lid body is plastic, the lower end of the lid body, the positioning link, the hole waterproof convex rib, the columnar body, the columnar shape Both the body waterproof convex rib and the columnar body positioning ring are preferably flexible glues.

  The plastic is preferably PC plastic (polycarbonate), ABS plastic (acrylonitrile butadiene styrene), or PC + ABS mixed plastic.

  The flexible glue is preferably silica gel or TPU (Thermoplastic polyurethane).

  It is preferable that a groove is formed outside the side wall of the lid.

  In the above-described embodiment of the present invention, the waterproof plug of the mobile terminal in the existing technology is mainly waterproofed by a system in which the structure that presses and closes on the main body side and the structure that the interference fit on the side wall is vertically closed and pressed and waterproofed is changed. The effect is improved, the area of the waterproof plug is large, the flexible glue is easily overhanged from the side surface, and it is possible to avoid defects that are screwed structures.

  The positive effects of the above embodiment of the present invention are as follows: The waterproof plug of the mobile terminal has a small fixing point in the side pressing structure, and avoids the problem that the plug tends to protrude from the side surface due to the elasticity of the flexible glue. Thus, the waterproof effect of the mobile terminal can be improved, the area of the waterproof plug can be reduced, and the screw for fixing the plug can be omitted.

It is a perspective view of the waterproof plug in the Example of the present invention. It is a figure which shows the opening structure of the case of the mobile terminal corresponding to the waterproof plug in the Example of this invention. It is an assembly drawing of the waterproof plug and the case of a mobile terminal in the Example of this invention. It is the longitudinal direction sectional view after assembling the waterproof plug and the case of the mobile terminal in the embodiment of the present invention.

  Hereinafter, in order to explain the technical solution of the present invention in detail, preferred embodiments of the present invention are presented in combination with the drawings.

  In an embodiment of the present invention, a waterproof plug for a mobile terminal is provided, and as shown in FIG. 1, a lid 11, a positioning link 12, and a hole waterproof convex rib 13 are provided, and the positioning link 12 is a lid. The hole waterproof convex rib 13 is provided at the lower end of the lid 11 and extends downward.

  In another embodiment of the present invention, a case of a mobile terminal coupled to the waterproof plug in the above embodiment is provided. As shown in FIG. 2, the case includes an I / O (Input / Output) element hole 21 and a case. The assembly hole 22 and the fixing groove 23 are provided, and the fixing groove 23 is coupled to the positioning link 12 to fix the waterproof plug. The position of the hole waterproof convex rib 13 corresponds to the I / O element hole 21 on the case 2 of the mobile terminal.
