Problems solved by technology
The traditional process is to first fit the main body with the iron shell, and then seal the back end with glue. This process has high cost and low efficiency. The glue will change due to the influence of the environment, and the reliability is poor.
The waterproofing in the prior art uses dispensing waterproofing and sealing ring waterproofing, but the airtightness is still lacking; and the waterproof connector has many parts, the assembly is complicated, and the cost is high; due to the large number of parts, the assembly bonding force is affected. The quality of assembly is affected, and there are too many cracks in the bonding between parts, which greatly reduces the airtightness and waterproofness of the entire product

The invention discloses a waterproof USB connector and a manufacturing method thereof. The waterproof USB connector comprises a third terminal module, a first waterproof ring sleeving the third terminal module, a first shell housing the third terminal module and the first waterproof ring, a second shell closing the rear end of the first shell and injection molded at the rear end of the first shell and a second waterproof ring sleeving the front end of the first shell, wherein a gap between the tail portion of the third terminal module and the interior of the first shell is completely filled by the second shell. By adopting the triple waterproof design, the waterproof sealing effect is ideal, and a present highest waterproof grade can be achieved; and the third terminal module and the second shell are obtained by virtue of the injection molding process and the embedding molding process, so that the connection sealability among various components of the waterproof USB connector is improved, and the waterproof function is effectively improved.
Description
【Technical field】 [0001] The invention belongs to the technical field of connectors, in particular to a waterproof USB connector and a manufacturing method thereof. 【Background technique】 [0002] With the rapid development of science and technology and the trend of the Internet era, computers have become a common tool for people's daily life and work. At present, due to the characteristics of good heat dissipation, easy hardware upgrade, and good self-protection, desktop computers are still widely used, such as servers with more application software, computers for industrial design, and special workbenches. With the widespread use of connectors, people have put forward higher requirements for connectors, such as waterproof. The traditional process is to first fit the main body with the iron shell, and then seal the rear end with glue. This process has high cost and low efficiency. The glue will vary due to the influence of the environment, and the reliability is poor. The...
