Abstract

A watertight connector has a shell, an insulating housing wrapped in the shell, a plurality of terminals mounted into the shell, a fixing element fixed on the shell. A rear of the insulating housing is recess to form a receiving cavity for receiving a fixing block molded with a plurality of terminals, so there is no hole between the terminals and the insulating housing. A fixing element is fixed on the shell to seal openings of the shell for providing excellent waterproof property. So, all the openings of the watertight connector are sealed tightly. Also, the structure of the watertight connector is simple for reducing the production cost.

Claims

1. A watertight connector, comprising:

an insulating housing having a base, a rear of the base recessed to form a receiving cavity for receiving a fixing block;

a shell for wrapping the insulating housing;

a plurality of terminals, each terminal including a base portion molded in the fixing block, a contact portion extended frontward into the insulating housing and a soldering portion exposed outside; and

a fixing element fixed on the shell for sealing holes defined in the shell.

2. The watertight connector as claimed in claim 1, wherein lateral sides of the receiving cavity are recessed to form a pair of fixing recesses matting with bumps protruded from lateral sides of the fixing block for fixing the fixing block together with the terminals into the receiving cavity.

3. The watertight connector as claimed in claim 1, wherein a front of the insulating housing is protruded to form a tongue, the tongue is recessed to form a plurality of terminal grooves extending frontward and rearwards communicating with the receiving cavity for accommodating the corresponding contact portions of the terminals.

4. The watertight connector as claimed in claim 1, wherein the shell has a top plate, two opposite ends of the top plate extended downward to form a pair of lateral plates, a bottom plate connecting bottom ends of the two lateral plates.

5. The watertight connector as claimed in claim 4, wherein a top of the base is protruded to form a first buckling portion having a front side recessed to form a first buckling recess for receiving a rear of the top plate, a bottom of the base is protruded to form a second buckling portion having a front side recessed to form a second buckling recess for receiving a rear of the bottom plate.

6. The watertight connector as claimed in claim 4, wherein the fixing element has a base slice fixed on the bottom plate for sealing a pair of second through holes formed at the base slice, two opposite ends of the base slice are extended upward to form a pair of lateral slices fixed on the lateral plates for sealing first through holes formed at the lateral plates.

7. The watertight connector as claimed in claim 6, wherein a portion of the lateral slice is punched outward to form a protrusion for avoiding any friction with a plug connector mated with the watertight connector.
