Description

Technical Field

[0001] The utility model relates to the technical field of wire harnesses, in particular to a highly flexible wire harness for locomotives. Background Art

[0002] A flexible manufacturing system is a system with complex technology and high automation. It mainly relies on highly flexible manufacturing equipment mainly composed of computer numerical control machine tools to achieve multi-variety production methods. Each component on the electric vehicle electrical system is connected by a wire harness. A flexible automotive wire harness refers to a component formed by pressing contact terminals (connectors) made of copper into wires and cables, and then plastically pressing an insulator or adding a metal shell outside, and bundling the wire harness to form a connecting circuit.

[0003] When optimizing the existing highly flexible wire harness for locomotives, most efforts are focused on making the wire harness have a longer service life. For example, the Chinese utility model patent with the application number CN201410218766.7 discloses "A Wire Harness and a Relay Wire Harness". The relay wire is formed by covering a third conductor (conductor) with a third insulating coating (coating material); a first housing is used to connect one end of the relay wire to the first wire harness by fitting with a first connector of the first wire harness; and a second housing is used to connect the other end of the relay wire to the second wire harness by fitting with a second connector of the second wire harness. The resin material for the coating layer forming the third insulating coating and the resin material for the housing forming the first housing and the second housing are both synthetic resins with a higher flame retardancy than the resin material of the first wire harness, thus extending the service life.

[0004] Although the above-mentioned highly flexible wire harness for locomotives has certain advantages in making the wire harness have a longer service life, it still has certain drawbacks: the wire harness can assist in binding high-flexibility wires of various specifications, while the conventional wire harness only allows the flexible wire to pass through. There is no flexible contact or flexible support at the contact between the wire harness and the flexible wire, which easily causes phenomena such as wear and breakage of the flexible wire.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the utility model provides a highly flexible wire harness for locomotives, which has the following beneficial effects:

[0018] 1. For this highly flexible wire harness for locomotives, the stable sleeve is press-fitted into the sleeve mouth, and the upper end of the auxiliary fixing component is installed with the outer bottom end of the stable sleeve by means of snap-fastening.

The moving body 41 penetrates into the interior of the fixing frame 46. The lower end of the moving body 41 is movably matched with the swing rod 44 through the round rod 42. The spring 43 is connected to both sides of the bottom end of the moving body 41. The connecting block 45 is welded to the outside of the fixing frame 46. The moving body 41 includes a clamping block 411, a horizontal plate 412, a hand rod 413, a vertical plate 414, a limiting groove 415, and a square block 416. The clamping block 411 is fixedly connected to the top end of the vertical plate 414. Both ends of the horizontal plate 412 are fixedly connected to the inner side walls of the vertical plate 414. The hand rod 413 is welded to the middle end of the horizontal plate 412 and is vertically arranged. The lower end of the vertical plate 414 is fixedly connected to the square block 416. The limiting groove 415 is arranged on the end face of the square block 416. The upper end of the moving body 41 is embedded and installed below the stabilizing sleeve 3. The vertical plate 414 is connected through the top end of the fixing frame 46. The bottom end of the square block 416 is wound and movably matched with the upper end of the spring 43. The limiting groove 415 is slidably engaged with the round rod 42. The clamping block 411 is pressed into the connection port 33. The connection port 33 is a groove hole at the bottom end of the outer side of the wire protection block 31, which is convenient for forming a clamping installation with the auxiliary fixing component 4. The limiting groove 415 is an irregular groove that is recessed on the end face of the square block 416. The bottom end of the round rod 42 contacts it. The position of the limiting groove 415 changes with the displacement of the square block 416, so that the round rod 42 displaces along the limiting groove 415, the swing rod 44 generates an inclination change, the top force on the square block 416 changes, and the square block 416 can be displaced downward in a reverse cooperation manner.

[0029] Please refer to Figure 5, a highly flexible wire harness for locomotives. The stabilizing sleeve 3 includes a wire protection block 31, an insertion port 32, a connection port 33, and a bracket 34. The insertion port 32 and the wire protection block 31 are of an integrated structure and are provided through the middle of the wire protection block 31. The connection port 33 and the wire protection block 31 are of an integrated structure and are arranged at the lower outer position of the wire protection block 31.

[0030] In summary, press the stabilizing sleeve 3 into the sleeve opening 5, and complete the installation of the upper end of the auxiliary fixing component 4 and the outer bottom end of the stabilizing sleeve 3 by means of snap-fastening installation. Then, pass the highly flexible wire 1 through the insertion port 32 and through the wire protection block 31, and install it on the wire harness fixing shell 2 to complete the bundling and integration of the wire. The through hole 6 can pass through steel wires, copper wires, etc. in the locomotive, so that the wire harness fixing shell 2 can assist the highly flexible wire 1 to be better arranged in the locomotive. By setting the auxiliary fixing component 4, when the stabilizing sleeve 3 needs to be replaced, the operator presses the hand lever 413, so that the vertical plate 414 drives the square block 416 to move downward, the position of the limiting groove 415 changes, and the position of the round rod 42 stuck on the limiting groove 415 is also different, causing the swing rod 44 to change its inclination, and the top force on the square block 416 also changes. In reverse cooperation, the square block 416 can move downward a greater distance, which is beneficial for the vertical plate 414 to drive the clamping block 411 downward, and make the clamping block 411 disengage from the connection port 33. Therefore, the connection port 33 loses the snap-fastening installation with the auxiliary fixing component 4, which is convenient for the operator to take out the stabilizing sleeve 3 from the sleeve opening 5 for replacement. After replacing with a new stabilizing sleeve 3, press the hand lever 413 again, so that the round rod 42 continues to move from top to right along the limiting groove 415. Under the elastic cooperation of the spring 43, an upward thrust is generated on the square block 416, so that the vertical plate 414 pushes the clamping block 411 upward, and makes the clamping block 411 snap into the connection port 33 to complete the installation of the auxiliary fixing component 4 and the stabilizing sleeve 3, and make the auxiliary fixing component 4 under the stabilizing sleeve 3 to play a better position fixing and cooperation for the stabilizing sleeve 3.
