Description

Technical Field

[0001] This utility model relates to the field of adapters, and in particular to a waterproof adapter. Background Technology

[0002] With continuous technological advancements, USB communication has become widely and maturely used in various electronic devices. As people's demands for communication speed continue to increase, USB communication protocols are constantly being upgraded, resulting in diverse communication interfaces. Today, consumer electronics devices increasingly emphasize user experience and larger multimedia file sizes, making the reversible Type-C interface a preferred choice for more and more manufacturers. However, devices using other connectors still constitute a significant portion of the market. Therefore, most manufacturers have developed adapters to switch between devices using different connectors.

[0003] The current manufacturing process for adapters is as follows: First, two connectors are soldered and fixed to a control board. Next, an inner mold is formed on the two connectors fixed together. Then, the inner mold is installed inside the outer shell. Finally, liquid silicone is formed at both ends of the outer shell. This process is relatively complex, and the bond between the liquid silicone and the outer shell is not strong and reliable enough, making it easy for the liquid silicone to be pulled out during insertion and removal, causing the adapter to lose its waterproof performance. Therefore, it is necessary to improve the existing adapter. Utility Model Content

[0013] (2) The conversion module obtained in step (1) is matched with the positioning workpiece. First, the first positioning part is inserted into the first insertion cavity, and then the outer shell is fitted. Then, the third positioning part is inserted into the third insertion cavity to obtain the pre-molding structure.

[0014] (3) Place the pre-molded structure obtained in step (2) into the mold core, close the mold, and injection mold the inner mold to finally obtain the waterproof converter.

[0015] As a preferred embodiment, both the surfaces of the second positioning part and the fourth positioning part are recessed to form waterproof rib grooves.

[0016] As a preferred embodiment, the first positioning member has a first groove, and one end of the outer shell is in close contact with the inner side of the first groove; the second positioning member has a second groove, and the other end of the outer shell is in close contact with the inner side of the second groove.

[0017] As a preferred embodiment, the first positioning member has a first positioning groove for positioning with the mold core, and the second positioning member has a second positioning groove for positioning with the mold core.

[0018] As a preferred embodiment, the inner diameter of the injection hole decreases sequentially from the outside to the inside.

[0019] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0020] The inner mold is formed into the storage cavity by injection molding, which gives the converter excellent waterproof performance. In addition, the inner wall of the storage cavity is provided with limiting ribs, which are embedded in the inner mold. This makes the combination of the inner mold and the outer shell strong and reliable, and will not be pulled out during insertion and removal, thus preventing the adapter from losing its waterproof performance.
