Abstract

A connector with fluid sealing including a male connector part having a rectangular body containing at least one contact pin. The outer peripheral surfaces of the rectangular body forming a male mating area. The connector further includes a female mating part containing at least one contact receptacle and having a rectangular opening adapted to receive the male connector part within the opening. The inner peripheral surfaces of the female connector part defining the rectangular opening forming a female mating area. A bead extends circumferentially around the entire periphery of one of the mating areas. The other of the mating areas has a groove extending circumferentially around the entire periphery and is adapted to receive the bead to create a fluid seal between the male and female connector parts.

Claims

1. A connector with fluid sealing between mated parts comprising:

a male connector part having a rectangular body containing at least one contact pin, an outer rectangular peripheral surface of said rectangular body forming a male mating area;

a female connector part, containing at least one contact receptacle, having a rectangular opening adapted to receive said male connector part within said opening, an inner rectangular peripheral surface of said female connector part defining said rectangular opening forming a female mating area, said rectangular peripheral surfaces and the location of said contact pins and contact receptacles limiting contact of said at least one contact pin and contact receptacle to a particular configuration; and

a bead extending circumferentially around the rectangular periphery of one of said male and female mating areas, the other of said male and female mating areas having a groove extending circumferentially around the rectangular periphery adapted to receive said bead to create a fluid seal between said male and female connector parts.

2. The connector with fluid sealing according to claim 1, wherein said male and female connector parts are movable along a mating axis to connect and disconnect said at least one contact pin and said at least one contact receptacle, said male and female mating areas being oriented parallel to the mating axis.

3. The connector with fluid sealing according to claim 2, wherein said bead has a bead height measured transverse to said mating axis, and the groove has a groove depth which is approximately equal to said bead height.

4. The connector with fluid sealing according to claim 3, wherein said bead has a bead width measured parallel to said mating axis, and said groove has a groove width which is slightly larger than said bead width.

5. The connector with fluid sealing according to claim 4, wherein said male mating area has a male mating area length measured in a direction parallel to said mating axis, and said female mating area has a female mating area length which is approximately equal to said male mating area length.

6. The connector with fluid sealing according to claim 5, wherein said male mating area has an end facing said at least one contact receptacle, said fluid seal is located substantially away from said end.

7. The connector with fluid sealing according to claim 6, wherein said male mating area includes a first region located between said fluid seal and said end and a second region located on the opposite side of said fluid seal;

said first region has a first region length measured in a direction parallel to said mating axis, and said second region has a second region length measured in a direction parallel to said mating axis that is less than half of said first region length.

8. The connector with fluid sealing according to claim 7, wherein said bead width is approximately 11/2 times the bead height.

9. The connector with fluid sealing according to claim 8, wherein the first region length is approximately four times the bead width.

10. The connector with fluid sealing according to claim 9, wherein said groove width is approximately twice the length of said groove depth.

11. A method for manufacturing male and female connector parts for a connector with fluid sealing, comprising the steps of:

cutting wires to a specified length;

stripping a predetermined length of insulation from an end of each of the wires;

crimping terminals to the stripped wire ends;

molding a male connector part over some of the wires and terminals to form a rectangular body, the outer rectangular peripheral surfaces of said rectangular body forming a male mating area;

molding a female connector part over others of the wires and terminals to form a rectangular opening adapted to receive said rectangular body within said opening, the inner rectangular peripheral surfaces of said female connector part defining said rectangular opening forming a female mating area;

molding a bead circumferentially around the rectangular periphery of one of said male and female mating areas; and

molding a groove circumferentially around the rectangular periphery of the other of said male and female mating areas, the groove being adapted to receive said bead to create a fluid seal between said male and female connector parts.

12. The method according to claim 11, wherein said steps of molding include molding by insert molding with insert molding injection machinery.

13. The method according to claim 12, wherein said steps of molding a male connector part, molding a female connector part, and molding a bead include molding a polyvinyl chloride molding compound.

14. The method according to claim 13, additionally comprising the step of

testing the polarization, continuity and die-electric characteristics of the connector, following said step of molding a groove.
