The present application is the National Stage of International Patent Application No. PCT/US2015/020143, filed on Mar. 12, 2015, which is hereby expressly incorporated herein by reference in its entirety.
The present invention relates generally to terminal assemblies for vehicles and, more particularly to, a low profile terminal assembly for holding a fuse for a vehicle.
It is known to provide a fuse holder for a removable electrical fuse. The fuse holder typically is in-line with a wire connected to a load and an unprotected wire connected to an eyelet, which is connected to a terminal of a battery. The fuse holder includes a housing and a cover pivotally attached to the housing, and configured to carry the electrical fuse. The fuse electrically interconnects the wires.
One disadvantage of the above fuse holder is that the fuse holder is spliced into the wiring harness and/or the electrical cable. Another disadvantage of the above fuse holder is that there is an unprotected wire between the fuse holder and the terminal for connection to the battery. Therefore, there is a need in the art to provide a new terminal assembly coupled to an electrical cable for engaging an electrical component to hold a fuse without requiring disassembly or alteration of the terminal assembly.
Accordingly, the present invention provides a terminal assembly for serviceably housing an electrical fuse. The terminal assembly includes a first terminal having a mounting end and a first fuse contacting end with the mounting end adapted for receiving a stud, a second terminal having a wire contacting end and a second fuse contacting end with the wire contacting end adapted for receiving an electrical cable, and a terminal housing securing the first terminal and the second terminal together. The terminal housing defines a cavity adapted for receiving a fuse. The first fuse contacting end of the first terminal and the second fuse contacting end of the second terminal extend into the cavity. The fuse is adapted to be inserted into the cavity and is disposed atop the first terminal and the second terminal without requiring disassembly or alteration of the terminal assembly.
One advantage of the present invention is that a new terminal assembly is provided for a vehicle that holds an electrical fuse therein. Another advantage of the present invention is that the terminal assembly is coupled to an electrical cable to hold an electrical fuse for engaging an electrical component. Yet another advantage of the present invention is that the terminal assembly does not require added splices to integrate into a wire harness. Still another advantage of the present invention is that the terminal assembly holds an electrical fuse without requiring disassembly or alteration of the terminal assembly. A further advantage of the present invention is that the terminal assembly serviceably houses slow blow cartridge type electrical fuses having a low profile configuration. Yet a further advantage of the present invention is that the terminal assembly holds an electrical fuse and is secured by a stud. Still a further advantage of the present invention is that the terminal assembly eliminates an unprotected “up stream” wire. Another advantage of the present invention is that the terminal assembly is smaller and less expensive than some fuse holders.
Other features and advantages of the present invention will be readily appreciated, as the same becomes better understood, after reading the subsequent description taken in conjunction with the accompanying drawings.
As disclosed in the
As illustrated in
The fuse 12 includes a fuse housing 24 having a pair of fuse terminals 26 and a fuse element 28 disposed therein. The fuse housing 24 is generally rectangular in shape, but may have any suitable shape. The fuse terminals 26 extend generally parallel from the fuse housing 24. The pair of fuse terminals 26 electrically couple the fuse element 28 between the first and second terminals 18, 20 as the fuse 12 is inserted into the terminal housing 22. The fuse terminals 26 are made of an electrically conductive material such as metal. It should be appreciated that the fuse 12 is preferably a slow blow cartridge type having a low-profile configuration.
The first terminal 18 includes a mounting end 30 having an aperture 32 for receiving the stud 16. The aperture 32 may be open ended, generally circular in shape, or may have any suitable shape. If the aperture 32 is closed, i.e. circular, then the mounting end 30 could be in the shape of an eyelet. The first terminal 18 also includes a first fuse contacting end 34 for coupling the first terminal 18 to one of the fuse terminals 26. In the embodiment illustrated, the first terminal 18 has a substantially L-shaped configuration such that an angle defined between the mounting end 30 and the first fuse contacting end 34 is approximately 90 degrees. In another embodiment, the first terminal 18 has a straight configuration between the mounting end 30 and the first fuse contacting end 34. In other embodiments, the first terminal 18 may have a multiple bend configuration between the mounting end 30 and the first fuse contacting end 34 to allow for various orientations. The mounting end 30 is directly connected to the first fuse contacting end 34. The first terminal 18 is made of an electrically conductive material such as metal. It should be appreciated that the first fuse contacting end 34 is generally planar. It should also be appreciated that the mounting end 30 of the first terminal 18 is directly adjacent the terminal housing 22.
The second terminal 20 includes a wire contacting end 36 for coupling the second terminal 20 to the electrical cable 14. The wire contacting end 36 is generally arcuate in shape for receiving the electrical cable 14. The second terminal 20 also includes a second fuse contacting end 38 for coupling the second terminal 20 to the other one of the fuse terminals 26. The second terminal 20 has a substantially L-shaped configuration such that an angle defined between the wire contacting end 36 and the second fuse contacting end 38 is approximately 90 degrees. The second terminal 20 is made of an electrically conductive material such as metal. The second fuse contacting end 38 is generally planar. It should be appreciated that the wire contacting end 36 is secured to the electrical cable 14 by a suitable mechanism such as crimping or welding.
The terminal housing 22 includes a first slot 40 for receiving the first terminal 18 and a second slot 42 for receiving the second terminal 20. The terminal housing 22 also includes a cavity portion 43 defining a cavity 44 for receiving the fuse 12. The first terminal 18 is disposed through the first slot 40 such that the first fuse contacting end 34 extends into the cavity 44. The second terminal 20 is disposed through the second slot 42 such that the second fuse contacting end 38 extends into the cavity 44. The first terminal 18 is spaced from the second terminal 20 while disposed within the terminal housing 22 such that the first and second terminals 18, 20 are electrically disconnected when the fuse 12 is not installed. Within the cavity 44, the first fuse contacting end 34 is disposed substantially parallel to the second fuse contacting end 38. Furthermore, the mounting end 30 of the first terminal 18 is substantially planar with the wire contacting end 36 of the second terminal 20. It should be appreciated that first fuse contacting end 34 is spaced from the second fuse contacting end 38 with the first fuse contacting end 34 and second fuse contacting end 38 being adapted to be electrically connected solely through the fuse 12.
The terminal housing 22 is generally rectangular in shape, but may be any suitable shape. The terminal housing 22 is made of a non-conductive material such as plastic. The terminal housing 22 may be formed as integral, unitary, and one-piece or as two pieces snapped together. In one embodiment, the terminal housing 22 is molded over the first terminal 18 and second terminal 20. It should be appreciated that the terminal housing 22 is typically molded by injection molding, but may be molded by any suitable process.
In operation of the terminal assembly 10, the fuse 12 is inserted into the cavity 44 of the terminal housing 22 and is disposed atop the first and second terminals 18, 20. Specifically, as the fuse 12 enters the cavity 44, the pair of fuse terminals 26 electrically couple to the first and second fuse contacting ends 34, 38. As such, electrical current may pass between the first and second terminals 18, 20 because the fuse 12 electrically connects the first and second terminals 18, 20 through the fuse element 28. It should be appreciated that the fuse 12 is secured within the cavity 44 of the terminal housing 22 by a suitable mechanism such as a friction fit.
