A wire guide ( 101 ) is disposable on a device such as a fuel injector ( 103 ). The wire guide ( 101 ) includes a channel ( 215 ) having one or more intermittently spaced fingers ( 213 ) along an open side of the channel ( 215 ). The fingers ( 213 ) may allow wires ( 205, 207 ) to enter the channel ( 215 ) easily, but inhibit the ability of the wires ( 205, 207 ) to leave the channel ( 215 ) once they enter. The channel ( 215 ) comprises an inner wall ( 301 ) that at least partially follows an outer contour of a device such as a fuel injector ( 103 ). One or more retaining members ( 219, 221 ) are included with the wire guide ( 101 ), such that the wire guide ( 101 ) is securable to the device, such as a fuel injector ( 103 ).
1. A wire guide for use in an engine, the wire guide comprising:
a channel having an open side with one or more intermittently spaced retaining fingers, wherein the channel comprises an inner wall that has a shape that mates at least partially with an outer contour of a fuel injector;
one or more retaining members operably connected to the channel, the one or more retaining members configured such that the wire guide is securable to a fuel injector;
wherein at least one wire disposed at least partially in the wire guide is guidable and protectable from moving parts underneath a valve cover in the engine.
2. The wire guide of claim 1 , wherein at least one of the retaining fingers is comprised of a flexible material that is narrower near one end.
3. The wire guide of claim 1 , wherein the one or more retaining members are capable of being inserted in at least one slot disposed along the outer contour of the fuel injector.
4. The wire guide of claim 1 , wherein at least one of the one or more retaining members is a flexible member disposed near an end of the channel.
5. The wire guide of claim 1 , wherein at least one of the one or more retaining members is disposed on the inner wall of the channel.
6. The wire guide of claim 1 , further comprising a base disposed near an end of the channel, wherein the base is disposable between an electrical overmold of a fuel injector and the fuel injector.
7. The wire guide of claim 1 , further comprising a base disposed near an end of the channel, wherein the base includes one or more extensions that are engagable with one or more edges of an electrical overmold of the fuel injector, such that the wire guide is inhibited from rotating about the fuel injector.
8. The wire guide of claim 1 , further comprising a support member disposed below the channel such that the wire guide is prevented from sliding down the outer contour of the fuel injector.
9. The wire guide of claim 1 , wherein the wire guide at least partially surrounds the outer contour of the fuel injector.
10. The wire guide of claim 1 , wherein at least one of the one or more intermittently spaced retaining fingers comprises a flexible finger disposed along the open side of the channel such that the flexible finger is capable of flexing to allow a wire to enter the channel.
11. The wire guide of claim 1 , wherein at least one of the one or more intermittently spaced retaining fingers comprises a flexible finger disposed along the open side of the channel such that when at least one wire is disposed in the channel, the flexible finger resists allowing the at least one wire to leave the channel.
12. The wire guide of claim 1 , wherein at least one of the one or more intermittently spaced retaining fingers is disposed on the inner wall of the channel, and wherein at least one of the one or more intermittently spaced retaining fingers is disposed on an outer wall of the channel.
13. The wire guide of claim 1 , wherein the channel is further comprised of an outer wall that is at least partially solid.
14. The wire guide of claim 13 , wherein the outer wall is comprised of one or more intermittent supports, wherein at least one of the retaining fingers is disposed at one of (a) an end of one of the one or more intermittent supports and (b) an edge of the inner wall.
15. The wire guide of claim 1 , wherein the retaining fingers comprise:
a tapered face;
an upper edge that forms an outer edge of the channel; and
a lower edge that borders a conduit.
16. The wire guide of claim 1 , wherein the retaining fingers are formed as one or more finger pairs along the open side of the channel, wherein each finger pair includes:
a first distance between the upper edges of the finger pair;
a second distance between the lower edges of the finger pair, wherein the first distance is larger than the second distance and wherein the finger pair results in an inverted wedge-shaped opening between the finger pair.
17. A wire guide for use in an engine, the wire guide comprising:
a channel having an open side with one or more intermittently spaced retaining fingers, wherein the channel comprises an inner wall that has a shape that mates at least partially with an outer contour of a fuel injector, and wherein at least a part of the channel is capable of flexing to allow a wire to enter the channel;
one or more retaining members operably connected to the channel, the one or more retaining members configured such that the wire guide is securable to a fuel injector;
wherein at least one wire disposed at least partially in the wire guide is guidable and protectable from moving parts underneath a valve cover in the engine.
18. The wire guide of claim 17 , wherein, when at least one wire is disposed in the channel, the one or more intermittently spaced retaining fingers resist allowing the at least one wire to leave the channel.
19. The wire guide of claim 17 , wherein the one or more intermittently spaced retaining fingers are capable of flexing to allow a wire to enter the channel.
20. The wire guide of claim 17 , wherein the one or more intermittently spaced retaining fingers are formed as a series of alternating opposing tabs along the open side of the channel.
21. A wire guide for use in an engine, the wire guide comprising:
a channel having an open side with one or more intermittently spaced retaining fingers, wherein the channel comprises an inner wall that has a shape that mates at least partially with an outer contour of a fuel injector;
one or more retaining members operably connected to the channel, the one or more retaining members configured such that the wire guide is securable to the fuel injector by the one or more retaining members and at least a part of the inner wall of the channel;
wherein at least one wire disposed at least partially guided in the wire guide.
22. The wire guide of claim 21 , wherein at least one of the one or more intermittently spaced retaining fingers comprises a flexible finger disposed along the open side of the channel such that the flexible finger is capable of flexing to allow a wire to enter the channel.
23. The wire guide of claim 21 , wherein at least one of the one or more intermittently spaced retaining fingers comprises a flexible finger disposed along the open side of the channel such that when at least one wire is disposed in the channel, the flexible finger resists allowing the at least one wire to leave the channel.
