## Abstract

A quick-disconnect waterproof connector for secure connection of electrical wires to one another in series, in applications where water or other fluids may be present. The most preferred connector has two connecting members each with opposing ends, a pin adjacent to a socket in side-to-side array at a first of said opposing ends, over-molding around the pin and socket, a plurality of external ribs laterally extending across the over-molding on opposing sides thereof, the over-molding around the base of the pin having a tapered boss, the over-molding extension around the distal end of the socket configured for snugly receiving the tapered boss of its paired member to create a waterproof connection, two sheathed insulated wires each connected to one of the contacts, and the over-molding also having on its second end a strain-relief extension positioned around the sheathed insulated wires as they enter the over-molding.

## Claims

### Claim 1

A quick-disconnect waterproof connector for secure connection of electrical wires to one another in series, said connector comprising:
two lengths of sheathed electrical wiring each comprising at least two insulated wires, each of said lengths of electrical wiring having an unsheathed end wherein said at least two insulated wires are separated from one another, and further wherein each said at least two insulated wires has an insulation-free tip;
two connecting members each formed from over-molding placed over and around said unsheathed end of one of said lengths of electrical wiring, said over-molding comprising a strain-relief extension making contact with a portion of said sheathed electrical wiring where said at least two insulated wires are not separated from one another and configured to provide a waterproof seal therebetween, and each said connecting member having an engagement end located remotely from said strain-relief extension;
at least one electrically-conductive pin and at least one electrically-conductive socket in side-to-side array with one another at said engagement end of said connecting member, said at least one electrically-conductive socket positioned within said over-molding and said at least one electrically-conductive pin positioned within said over-molding so that part thereof remains extending beyond said over-molding, each said at least one electrically-conductive pin and each said at least one electrically-conductive socket placed in electrical communication with a different one of said insulation-free tips of said at least two insulated wires positioned within said over-molding of each said connecting member, with the number and positioning of said at least one pin present in one said connecting member allowing for engagement therewith by one of said sockets in the other one of said connecting members in opposed relation thereto, and the number and positioning of said at least one socket present in the same one of said connecting members allowing for engagement therewith by one of said pins in the other one of said connecting members pin in opposed relation thereto;
a portion of said over-molding on each said connecting member that is located immediately around each said at least one pin having a tapered boss; and
a portion of said over-molding on each said connecting member located adjacent to said at least one socket being in the form of a straight-walled extension configured for snugly receiving one said tapered boss so as to provide a waterproof seal therebetween, wherein when said engagement ends of both said connecting members are joined together, said electrically-conductive pins and said electrically-conductive sockets in opposed relation are placed in watertight electrical communication with one another, thus providing secure and reliable electrical communication between said two lengths of sheathed electrical wiring.

### Claim 2 (depends on 1)

The connector of claim 1 wherein said two connecting members each have a configuration identical to the other.

### Claim 3 (depends on 1)

The connector of claim 1 wherein said over-molding in each said connecting member has an exterior surface with a plurality of ribs laterally extending across said exterior surface.

### Claim 4 (depends on 3)

The connector of claim 3 wherein said exterior surface of said over-molding has opposed sides, said ribs are present on both of said opposed sides, and said ribs are further configured to allow said connecting members to become completely pressed together to make a watertight connection and seal therebetween with low insertion installer-applied connection forces.

### Claim 5 (depends on 3)

The connector of claim 3 wherein said ribs are widely spaced apart from one another on said exterior surface.

### Claim 6 (depends on 1)

The connector of claim 1 wherein each said at least one electrically-conductive pin and each said at least one electrically-conductive socket in each said connecting member has a wire terminal that is configured for crimping around one said insulated wire and said insulation-free tip adjacent thereto.

### Claim 7 (depends on 6)

The connector of claim 6 wherein said wire terminal further comprises a smaller wire terminal component configured for being crimped around one said insulated wire and a larger wire terminal component having a longer length dimension than said smaller wire terminal component, and is configured for being crimped around one said insulation-free tip.

### Claim 8 (depends on 1)

The connector of claim 1 each said pin further comprises a non-uniform diameter dimension.

### Claim 9 (depends on 8)

The connector of claim 8 wherein said narrowing tips of said pins and said straight-walled extensions associated with said sockets in each said connecting member have identical positioning in distance relative to said strain-relief extension associated with the same one of said connecting members.

### Claim 10 (depends on 1)

The connector of claim 1 wherein each said pin has a narrowing tip extending beyond said over-molding.

### Claim 11 (depends on 10)

The connector of claim 10 each said pin further comprises a non-uniform diameter dimension adjacent to said narrowing tip.

### Claim 12 (depends on 1)

The connector of claim 1 wherein each said pin is substantially inserted into a paired one of said sockets during connector use.

### Claim 13 (depends on 1)

The connector of claim 1 wherein said pins and said sockets are centered within said over-molding.

### Claim 14 (depends on 1)

The connector of claim 1 wherein a major portion of each said pin extends from said over-molding.
