[0030] For the wiring device of the mechanical equipment wiring harness provided in this embodiment, when the docking terminal is inserted into the docking groove 5, the anti - detachment pressure plates 6 provided on the two opposite inner walls of the docking groove 5 can clamp both sides of the docking terminal. When the docking terminal is inserted into the docking groove 5 along the inclined second outer wall 62 of the anti - detachment pressure plate 6, the inclined second outer wall 62 of the anti - detachment pressure plate 6 can gradually increase the friction force on the docking terminal as the docking terminal is inserted, thereby strengthening the connection between the terminal block 2 and the docking terminal.

[0036] For the wiring device of the mechanical equipment wire harness provided in this embodiment, the support plate 8 inside the filling airbag 7 can provide a supporting force for the anti - detachment pressure plate 6, further increasing the pressure of the anti - detachment pressure plate 6 on the docking terminal when the docking terminal is inserted into the docking groove 5, and thus improving the clamping force of the wiring terminal 2 on the docking terminal measurement.

[0038] This embodiment provides a wiring device for a mechanical equipment wire harness. On the basis of Embodiment 1, as Figure 4 shown, the connection part between the first outer wall 61 and the second outer wall 62 of the anti - detachment pressure plate 6 is arc - shaped.
[0039] In this embodiment, the inclination angle of the second outer wall 62 of the anti - detachment pressure plate 6 relative to the two inner walls opposite to the docking groove 5 is 10° - 15°.
[0040] For the wiring device of the mechanical equipment wire harness provided in this embodiment, the connection part between the first outer wall 61 and the second outer wall 62 of the anti - detachment pressure plate 6 is arc - shaped, which can facilitate the insertion of the docking terminal into the docking groove 5. Compared with the perpendicular connection between the first outer wall 61 and the second outer wall 62, it can avoid scratching the docking terminal caused by the right angle and extend the service life of the docking terminal.

[0044] In use, first insert the docking terminal into the docking slot 5, and clamp both sides of the docking terminal through the anti - detachment pressure plates 6 provided on two opposite inner walls of the docking slot 5 to achieve the primary reinforcement of the connection between the wiring terminal 2 and the docking terminal; then bypass the tail end of the docking terminal with the anti - detachment binding strip 4, and apply pressure to the tail end of the docking terminal through the elastic restoring force of the anti - detachment binding strip 4 to achieve the secondary reinforcement of the connection between the wiring terminal 2 and the docking terminal.
[0045] Embodiment 6:
[0046] This embodiment provides a wiring device for a mechanical equipment wire harness. On the basis of Embodiment 5, as Figure 3 shown, the anti - detachment binding strip 4 includes an elastic connection band 41 and connection hooks 42 provided at both ends of the elastic connection band 41 for clamping with the fixed rod 3.
[0047] For the wiring device of the mechanical equipment wire harness provided in this embodiment, the detachable connection between the anti - detachment binding strip 4 and the wiring terminal 2 is realized by clamping the connection hook 42 with the fixed rod 3, making the secondary reinforcement more convenient and flexible.
[0048] When performing the secondary reinforcement on the connection between the wiring terminal 2 and the docking terminal, first clamp the connection hook 42 at one end of the elastic connection band 41 with the fixed rod 3 provided on one outer wall of the wiring terminal 2, then bypass the tail end of the docking terminal with the elastic connection band 41, and then clamp the connection hook 42 at the other end of the elastic connection band 41 with the fixed rod 3 provided on the other outer wall of the wiring terminal 2.

[0051] For the wiring device of the mechanical equipment wire harness provided in this embodiment, the adjustment of the binding length of the elastic connection band 41 is realized through the cooperation of the first clamping hook 43 and the second clamping hook 44, so that the anti - detachment binding strip 4 can be applicable to docking terminals of various different sizes, and the connection between the wiring terminal 2 and docking terminals of various different sizes can be secondarily reinforced.
[0052] When performing secondary reinforcement on the connection relationship between the connection terminal 2 and various docking terminals of different sizes, first, respectively snap the connection hooks 42 at both ends of the elastic connection band 41 onto the fixed rods 3 provided on two opposite outer walls of the wiring terminal 2. Then, bypass the elastic connection band 41 around the tail end of the docking terminal, and according to the size of the docking terminal, select a set of first snap hooks 43 and second snap hooks 44 to snap and adjust the binding length of the elastic connection band 41, so that the adjusted binding length of the elastic connection band 41 can fasten the docking terminal. By applying pressure to the tail end of the docking terminal through the elastic restoring force of the elastic connection band 41, secondary reinforcement of the connection between the wiring terminal 2 and the docking terminal is achieved.
[0053] For various docking terminals of different sizes, only by selecting different sets of first snap hooks 43 and second snap hooks 44 to snap, the secondary reinforcement of the connection relationship between the wiring terminal 2 and various docking terminals of different sizes can be achieved.
[0054] For example: when the size of the docking terminal is large, select a set of first snap hooks 43 and second snap hooks 44 far from the connection hook 42 to snap and adjust the binding length of the elastic connection band 41, so that the adjusted binding length of the elastic connection band 41 can fasten the docking terminal; when the size of the docking terminal is small, select a set of first snap hooks 43 and second snap hooks 44 close to the connection hook 42 to snap and adjust the binding length of the elastic connection band 41, so that the adjusted binding length of the elastic connection band 41 can fasten the docking terminal.
