[0051] When it is necessary to remove the tail protection shell 20 , the operation of installing the tail protection shell 20 can be performed in reverse.

[0052] In the above-mentioned root wire harness protection structure, a tail protective shell 20 is arranged at the tail end of the connector body 10, and the tail protective shell 20 is assembled by a fixed lock buckle 40, so that the tail protective shell 20 wraps the wire harness located at the tail of the connector body 10, and at the same time, the tail protective shell 20 is connected and fixed to the connector body 10 by a locking member 30, so as to avoid the situation that the tail protective shell 20 slides due to external force and fails to protect the wire harness, and the tail protective shell 20 can achieve the effect of quick disassembly and assembly through the locking member 30 and the fixed lock buckle 40, so that it is convenient to remove the protective shell when the tail wire harness needs to be repaired.

[0053] In some embodiments, the outer side of the first shell 210 and the outer side of the second shell 220 are both provided with a protrusion 230, and the protrusion 230 is provided with a mounting groove 231 along the axial direction of the tail protection shell 20, and the notch direction of the mounting groove 231 is consistent with the port direction of the connection end of the connector body 10.

[0054] When assembling the first shell 210 or the second shell 220 , the protrusion 230 is grooved to facilitate the placement of the locking member 30 , and then the auxiliary protrusion 232 is placed at the notch of the installation groove 231 and a hole is drilled in the auxiliary protrusion 232 to facilitate the installation of the connecting cross bar 310 .

[0055] In some embodiments, continue to refer to Figure 3 , Figure 3 FIG. 2 is a schematic diagram of the structure of the tail protection shell 20 in an embodiment of the present application, wherein two connecting cross bars 310 are provided.

[0057] The connecting cross bar 310 and the connecting vertical bar 320 are connected and fixed to form an L-shaped structure, and then the two connecting vertical bars 320 are connected by a plurality of first elastic members 340. During installation, the two connecting vertical bars 320 are driven to move toward each other and compress the first elastic members 340, and then the connecting vertical bars 320 are placed in the installation groove 231 until the connecting cross bar 310 is aligned with the first through hole 233. At this time, the first elastic members 340 are unfolded so that the connecting cross bar 310 passes through the first through hole 233.

[0058] When the connecting cross bar 310 passes through the first through hole 233, the pressing piece 330 passes through the second through hole 234 and is connected to the connecting vertical bar 320. In an exemplary embodiment, a thread groove is provided on the connecting vertical bar 320, and when the connecting cross bar 310 passes through the first through hole 233, the thread groove is aligned with the second through hole 234, and a thread section is provided at the end of the pressing piece 330, and the thread end of the pressing piece 330 matches the thread groove of the connecting vertical bar 320.

[0059] In some embodiments, continue to refer to Figures 1 to 4 A limiting protrusion 350 is disposed on the side of the connecting vertical rod 320, and the limiting protrusion 350 faces the inner wall of the mounting groove 231 when the connecting horizontal rod 310 passes through the first through hole 233. At the same time, a limiting groove 235 is formed on the inner wall of the mounting groove 231, and the limiting groove 235 matches the limiting protrusion 350.

[0060] The movement direction of the locking member 30 is controlled by the cooperation between the connecting cross bar 310 and the first through hole 233, the cooperation between the pressing member 330 and the second through hole 234, and the cooperation between the limiting groove 235 and the limiting protrusion 350, so as to avoid the locking member 30 from falling off when the fixed connection between the locking member 30 and the connector body 10 is released.

[0061] In some embodiments, see Figure 5 , Figure 5 FIG. 2 shows a left side view of a tail protection shell 20 provided in an embodiment of the present application. Figures 1 to 4 The fixed lock 40 includes a lock body and a lock tongue. The first lock body and the first lock tongue are respectively disposed on both sides of the first housing 210, and the second lock body and the second lock tongue are respectively disposed on both sides of the second housing 220. The first lock body and the second lock tongue are located on the same side of the tail protection shell 20, and the second lock body and the first lock tongue are located on the same side of the tail protection shell 20.

[0064] Continue reading Figures 1 to 6The lock body also includes two unlocking members 430 and a plurality of second elastic members 440. Each unlocking member 430 includes an unlocking cross bar 431. The unlocking cross bar 431 is arranged inside the lock body shell 420. Two first protrusions 421 and second protrusions 422 are arranged inside the lock body shell 420. Each unlocking cross bar 431 is connected to the adjacent first protrusion 421 and second protrusion 422 through the second elastic member 440. The two unlocking cross bars 431 are provided with unlocking push blocks 432 facing each other. The unlocking push blocks 432 abut against the lock tongue protrusion of the lock tongue member 410. The two unlocking cross bars 431 are provided with unlocking protrusions 433 facing each other. The unlocking protrusions 433 pass through the shell. Among them, the second elastic member 440 can be, but not limited to, a spring, and can also be other elastic and fatigue-resistant elastic components.

At this time, the first shell 210 abuts the second shell 220, the first protrusion 421 restricts the lock tongue protrusion, and each lock tongue protrusion abuts an unlocking push block 432.

[0066] When the tail protection shell 20 needs to be removed, the unlocking protrusion 433 is pressed so that the unlocking protrusion 433 pushes the unlocking cross bar 431, and the unlocking cross bar 431 moves toward each other, and the unlocking push block 432 squeezes the lock tongue protrusion. When the lock tongue protrusion is squeezed, the ends of the vertical rod of the lock tongue member 410 are close to each other, and the first shell 210 can be separated from the second shell. Then the unlocking protrusion 433 is released, and the second elastic member 440 recovers and restores the lock body to its original state.
