Waterproof connector and manufacturing method thereof
The present disclosure discloses a waterproof connector including an integral insulating body, a number of conductive terminals, and an insulating block. The insulating body includes a rear end portion, a front end portion, and a middle portion. The rear end portion defines a number of terminal grooves. The front end portion defines a mating space. The middle portion includes a receiving channel communicating with the terminal grooves. The terminals are disposed in the terminal grooves and extend towards the mating space. The insulating block is injection-molded in the receiving channel and seamlessly fixes the conductive terminals in the terminal grooves. The waterproof connector of the present disclosure can prevent water and dust from entering therein. A method of manufacturing the waterproof connector is also provided.
1. A method of manufacturing a waterproof connector comprising following steps:
step 1: injection-molding an insulating body during which an upper mold, a lower mold and a plurality of pin members are used for defining a receiving channel and a plurality of terminal grooves;
step 2: inserting a plurality of conductive terminals into the terminal grooves of the insulating body from a back-to-front direction;
step 3: injecting plastic or rubber into the receiving channel to form an insulating block;
step 4: assembling a metal shell outside the insulating body; and
step 5: connecting the conductive terminals to a printed circuit board and thereafter injection-molding a baffle between the insulating body and the printed circuit board.
2. The method according to claim 1 , wherein at least two locking beams are inserted into the insulating body from the back-to-front direction together with the conductive terminals in the step 2.
