Description

TECHNICAL FIELD

[0001] The utility model relates to a wire harness, concretely relates to a wire harness convenient for adjusting plug -in direction. BACKGROUND

[0002] The wire harness of engineering machinery vehicle as the important component of electrical system, its work stability is directly related to the performance and reliability of engineering machinery vehicle, once the wire harness appears the fault, can cause engineering machinery vehicle to stop or operate unsafe, this not only can influence production efficiency, also can cause the danger to the working environment. In order to guarantee the stability of wire harness work, first, guarantee wire harness terminal and engineering vehicle terminal joint can be firmly inserted, for this, need to guarantee the angle of wire harness terminal and engineering vehicle terminal joint when two are inserted, in ideal case, wire harness terminal and engineering vehicle terminal joint coaxial butt joint. But because wire harness outside is all equipped with the hard texture sheath that protects, so wire harness can not directly bend at a large angle, in order to solve this problem, current wire harness manufacturers all increase wire harness length to guarantee that there is enough margin to gradually adjust the direction of wire harness terminal. Many cases will be connected to a plurality of branch wire harness on a bus harness, different branch wire harness connects corresponding terminal joint, and the current branch wire harness branches from the bus harness is all the sheath of the bus harness is drilled in advance, then the branch wire harness is drilled out by the drilling hole on the sheath, and the branch wire harness adjusts the plug-in direction and is affected by the drilling hole position on the sheath, if the drilling hole position is directly opposite the terminal joint, then the branch wire harness does not need to adjust the direction, and can be directly plugged in, if the drilling hole position is directly opposite the terminal joint, since the sheath is an integral whole, the branch wire harness cannot drive the sheath to rotate as a whole, so the branch wire harness needs to adjust the direction by 180 degrees, that is, the branch wire harness needs to reserve a large amount of margin for the branch wire harness to adjust the direction by 180 degrees, and the sheath cannot predict the relative angle of the drilling hole and the terminal joint in advance when drilling, so the branch wire harness reserves the length in the case of needing to adjust the direction by 180 degrees. For wire harness manufacturers, increasing the length of the wire harness will inevitably increase the cost, so how to adjust the plug-in direction of the wire harness without increasing the length of the wire harness and increasing the cost has become a problem that wire harness manufacturers need to solve.

[0017] The utility model will be further described below with reference to the drawings.

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0019] As Figures 1 to 5 shown, the utility model provides a technical scheme: including bus harness sheath 1 and a plurality of sub-harness, each sub-harness is equipped with sub-harness sheath 2 outside to protect its inside sub-harness, and the end of sub-harness is equipped with terminal 4 to be connected with terminal connector, and all sub-harness is equipped with bus harness sheath 1 outside;Bus harness sheath 1 is bellows, when sub-harness needs to branch external connection, bus harness sheath 1 is disconnected from branch external connection and is connected through buckle tee 3, namely bus harness sheath 1 is divided into two at branch external connection;As Figure 4 and Figure 5As shown, the buckle type tee joint 3 is a symmetrical two-leaf type clamping structure, including two semicircular main channels 31 and two semicircular branch channels 32, the inner side of the circumferential direction of the two semicircular main channels 31 is hingedly connected, and an arc-shaped limiting card 33 is arranged at the position close to the two ends of the inner wall of the two semicircular main channels 31. The two semicircular main channels 31 can be folded and fitted along the hinge to form a circular main channel. A semicircular branch channel 32 is arranged at the middle position of the outer side of the circumferential direction of the two semicircular main channels 31. When the two semicircular main channels 31 are folded and fitted, the two semicircular branch channels 32 are also fitted to form a circular branch channel. After the buckle type tee joint 3 is buckled, the disconnected bus beam sheath 1 is connected by the main channel, and the branch external sub-wire harness is connected to the bus beam sheath 1 outside by the branch channel. Since the bus beam sheath 1 is a corrugated pipe, and the arc-shaped limiting card 33 is arranged at the position close to the two ends of the inner wall of the two semicircular main channels 31, after the buckle type tee joint 3 is buckled, the limiting card 33 will be clamped on the bus beam sheath 1, preventing the axial movement of the bus beam sheath 1 while not affecting the circumferential rotation of the bus beam sheath 1. This structure makes it unnecessary to lengthen the sub-wire harness when the plug-in connection of the terminal connector 4 and the terminal connector needs to be adjusted in direction. It only needs to rotate the buckle type tee joint 3 to drive the sub-wire harness to rotate circumferentially to adjust the plug-in direction of the sub-wire harness, i.e. the terminal connector 4 and the terminal connector. The reason why the sub-wire harness can rotate circumferentially at the buckle type tee joint 3 is that the bus beam sheath 1 is in a disconnected state rather than an integral whole at this position, so it will not limit the circumferential rotation of the sub-wire harness.

[0020] As Figure 2 and Figure 3 , the sub-wire harness sheath 2 is provided with a fracture 21 at a position 8 cm away from the inner end face of the terminal connector 4, and a rubber bending sheath 5 is arranged outside the fracture 21. The length of the bending sheath 5 is greater than the length of the fracture 21, and the two ends of the bending sheath 5 are connected with the sub-wire harness sheath 2 before and after the fracture 21. The fracture 21 is replaced by the bending sheath 5 on the sub-wire harness sheath 2, and the bending sheath 5 is slightly softer than the sub-wire harness sheath 2. Therefore, when the plug-in direction of the terminal connector 4 and the terminal connector needs to be adjusted, the sub-wire harness can be bent at the position of the bending sheath 5 without the need to increase the length of the sub-wire harness. The bending sheath 5 can meet the demand of large-angle bending and also protect the sub-wire harness. Since the distance between the fracture 21 and the inner end face of the terminal connector 4 is 8 cm, even if the bending sheath 5 is damaged, the terminal connector 4 can be pulled out and a new bending sheath 5 can be embedded, which is convenient for maintenance and replacement.

[0021] It is apparent to those skilled in the art that the present application is not limited to the details of the foregoing exemplary embodiments, and that the present application can be implemented in other particular forms without departing from the spirit or essential characteristics of the present application.
