Method for manufacturing connector

A method for manufacturing a connector, comprising:

• obtaining a terminal module comprising a terminal body and a plurality of terminals, wherein the terminal body comprises an interface part, a hollow area, and an electrical connecting part;
• the hollow area being disposed between the interface part and the electrical connecting part;
• the plurality of terminals being disposed on the terminal body;
• and each terminal passing through the interface part, the hollow area, and the electrical connecting part;
• assembling a housing on the terminal module, wherein the hollow area passed by the plurality of the terminals is exposed from the housing;
• inject-molding a waterproof block into the hollow area, wherein the waterproof block encases the plurality of the terminals disposed in the hollow area;
• and the waterproof block is disposed between the interface part and the electrical connecting part;
• and
• inject-molding a waterproof ring on an outer wall of the housing close to the interface part;
• wherein the step of inject-molding the waterproof block into the hollow area and the step of inject-molding the waterproof ring on the outer wall of the housing close to the interface part are performed simultaneously in the same inject-molding process.
