Canted coil spring power terminal and sequence connection system
View Patent ↗The present invention provides an electrical power system comprising a plurality of battery modules in series connection between adjacent battery modules, wherein each of the battery modules comprises a positive male terminal, a negative male terminal, and a socket corresponding to each of the positive male terminals and the negative male terminals. The connectors connecting the adjacent battery modules include a sequence tab that provides an irreversible engagement sequence of the connectors into the sockets of the adjacent battery modules. The irreversible engagement sequence positions an insulating portion of the connectors housing on each positive male terminal of the battery modules that are in series connection in order to isolate the positive male terminals from human contact. The present invention also provides a female terminal including a canted coil spring positioned within a stamped groove that may be housed within the above-described connectors.
1. In an electrical terminal having a female body including an opening, a spring, and a groove communicating with said opening for housing said spring internally of said opening, the improvement wherein said groove is formed by a stamping process performed on said female body, wherein said female body includes a sheet of stamped metal having a first portion containing one side of said opening and a second portion folded over so as to be in contact with said first portion, said second portion containing an opposite side of said opening and cooperating with said first portion to form said groove, and wherein a dimension defining said diameter of said spring is perpendicular to a dimension defining a length of said female body.
2. The electrical terminal of claim 1 , wherein said spring is curvilinear in shape.
3. The electrical terminal of claim 1 , wherein said spring reversibly interlocks with a groove formed on a male terminal body.
4. The electrical terminal of claim 1 , wherein the dimension defining the diameter of said spring is parallel to the dimension defining the length of said female body.
5. The electrical terminal of claim 1 , wherein said opening of said female body is substantially cylindrical.
6. The electrical terminal of claim 1 , wherein said female body includes another opening, said openings being separated by a distance.
7. The electrical terminal of claim 6 , wherein said distance is adjustable.
8. The electrical terminal of claim 7 , further comprising a flexible U-shaped loop disposed between said openings, whereby said distance may be adjusted by manipulating said loop.
9. The electrical terminal of claim 1 , further comprising a connector housing which is movable from a sealed configuration to an unsealed configuration, said female body engaging a male terminal body in said connector housing.
10. The electrical terminal of claim 1 , wherein said groove includes a cylindrical sleeve, said spring being press fitted into said sleeve.
11. The electrical terminal of claim 1 , wherein said opening is sized and shaped so as to receive a male terminal body.
12. The electrical terminal of claim 1 , wherein said spring is a canted coil spring.
13. The electrical terminal of claim 1 , wherein said opening is substantially polyhedron shaped.
14. An electrical terminal, comprising:
a female body including a sheet of stamped metal having a first portion containing one end of a first opening, a second portion containing an opposite end of said first opening, a third portion containing one end of a second opening and a fourth portion containing an opposite end of said second opening, said second portion being folded over so as to be in contact with said first portion such that said ends of said first opening are aligned, and said fourth portion being folded over so as to be in contact with said third portion such that said ends of said second opening are aligned;
first and second grooves formed in said first and second openings, respectively;
a first spring disposed in said first groove;
a second spring disposed in said second groove; and
a flexible loop disposed between said openings, said openings being separated by a distance, whereby said distance may be adjusted by manipulating said loop.
15. The electrical terminal of claim 14 , wherein said first and second grooves are formed by a stamping process performed on said female body.
