Abstract

An electrical accessory for a vehicle includes a housing having a connector portion having a connector cavity therein, and a plurality of terminals that electrically connect at a circuit element in the housing and that protrude at least partially into the connector cavity. The housing has at least one fill port and at least one channel for receiving a sealant material through the fill port, whereby the sealant material flows along the at least one channel and at and around at least one terminal to substantially seal the at least one terminal relative to the housing. The fill port is accessible from outside of the housing after the electrical accessory is assembled.

Claims

1. An electrical accessory for a vehicle, said electrical accessory comprising:

a housing having a connector portion having a connector cavity therein;

a plurality of terminals that electrically connect at a circuit element in said housing and that protrude at least partially into said connector cavity;

wherein said housing comprises at least one fill port and at least one channel for receiving a sealant material through said fill port, whereby said sealant material is dispensed at said at least one fill port and flows along said at least one channel and at and around individual terminals of said plurality of terminals to substantially seal said individual terminals relative to one another and relative to said housing; and

wherein said fill port is accessible from outside of said housing after said electrical accessory is assembled.

2. The electrical accessory of claim 1, wherein said at least one fill port and said at least one channel comprise a plurality of fill ports and a plurality of channels, with said fill ports associated with respective channels.

3. The electrical accessory of claim 2, wherein said sealant is dispensed through each of said fill ports to substantially seal respective terminals at respective channels.

4. The electrical accessory of claim 1, wherein said sealant is injected into said at least one fill port.

5. The electrical accessory of claim 1, wherein said sealant is dispensed at said at least one fill port when in uncured state, and wherein said sealant is cured after it is dispensed to a cured state of substantially seal said at least one terminal relative to said housing.

6. The electrical accessory of claim 5, wherein said sealant is UV cured to said cured state.

7. The electrical accessory of claim 1, wherein said electrical accessory comprises a fuel controller of a vehicle.

8. The electrical accessory of claim 1, wherein said connector portion comprises a plug or socket connector portion and wherein said plurality of terminals comprises pins of a multi-pin connector of said plug or socket connector portion.

9. A method of manufacturing an electrical accessory, said method comprising:

providing a housing having a connector portion having a connector cavity therein, wherein said housing comprises at least one fill port and at least one sealant channel;

assembling a circuit element and a cover at said housing so that said circuit element is substantially housed by said housing and said cover;

providing a plurality of terminals and electrically connecting said terminals at said circuit element in said housing, whereby said terminals protrude at least partially into said connector cavity;

accessing said at least one fill port from outside said housing after said circuit element and said cover are assembled at said housing and after said terminals are electrically connected at said circuit element; and

dispensing a sealant material through said at least one fill port so said sealant material flows along said at least one channel and at and around individual terminals of said plurality of terminals to substantially seal said individual terminals relative to one another and relative to said housing.

10. The method of claim 9, wherein said at least one fill port and said at least one channel comprise a plurality of fill ports and a plurality of channels, with said fill ports associated with respective channels.

11. The method of claim 10, wherein dispensing a sealant comprises dispensing a sealant through each of said fill ports to substantially seal respective terminals at respective channels.

12. The method of claim 9, wherein dispensing a sealant material comprises dispensing a sealant material in an uncured state, and wherein said method includes curing said sealant material to a cured state after said sealant material is dispensed to substantially seal said at least one terminal relative to said housing.

13. The method of claim 12, wherein curing said sealant material comprises curing said sealant material via a UV curing process.

14. The method of claim 9, wherein said connector portion comprises a plug or socket connector portion and wherein said plurality of terminals comprises pins of a multi-pin connector of said plug or socket connector portion.

15. An electrical accessory for a vehicle, said electrical accessory comprising:

a housing having a connector portion having a connector cavity therein;

a plurality of terminals that electrically connect at a circuit element in said housing and that protrude at least partially into said connector cavity;

wherein said connector portion comprises a plug or socket connector portion and wherein said plurality of terminals comprises pins of a multi-pin connector of said plug or socket connector portion;

wherein said housing comprises at least one fill port and at least one channel for receiving a sealant material through said fill port, whereby said sealant material, when in its uncured state, is injected into said at least one fill port and flows along said at least one channel and at and around individual pins of said plurality of terminals, and wherein said sealant material is cured to a cured state to substantially seal said individual pins relative to one another and relative to said housing; and

wherein said fill port is accessible from outside of said housing after said electrical accessory is assembled.

16. The electrical accessory of claim 15, wherein said at least one fill port and said at least one channel comprise a plurality of fill ports and a plurality of channels, with said fill ports associated with respective channels.

17. The electrical accessory of claim 16, wherein said sealant is dispensed through each of said fill ports to substantially seal respective terminals at respective channels.

18. The electrical accessory of claim 17, wherein said channels correspond with respective ones of the sealant fill ports, such that, when said sealant material is injected into a respective port, the sealant material flows along the respective channel to fill in the channel and surround and seal at the terminals disposed along that channel.

19. The electrical accessory of claim 15, wherein said sealant is UV cured to said cured state.

20. The electrical accessory of claim 15, wherein said electrical accessory comprises a fuel controller of a vehicle.
