[0037] According to the present disclosure, a wire harness sheath fixing module is used to fix the inner core of the sheath and the assembled sheath, such as... Figure 1 As shown in 7, including,

[0038] The outer casing 10 is configured to have a first cavity 11 with a top opening;

[0039] The inner housing 12 is configured as a second cavity 13 with a top opening, and the inner housing 12 is disposed within the first cavity 11 and is switchable between a first position and a second position;

[0040] A limiting structure is provided on the outer shell 10 to limit the inner shell 12 to the first position, so that the outer shell 10 is fixedly assembled with the sheath through the first cavity 11.

[0041] At least one biasing member 14 is disposed between the inner housing 12 and the outer housing 10, providing a biasing force to the inner housing 12 to switch from the first position to the second position, so that the inner housing 12 fixes the inner core of the sheath through the second cavity 13.

[0042] When the inner housing 12 is set in the first position by the limiting structure, the assembled sheath is fixed by the first cavity 11. The offset component 14 switches the inner housing 12 from the first position to the second position, and the inner core of the sheath is fixed by the inner housing 12. The two states that occur during the assembly of the wire harness sheath at the same position are realized by using a wire harness sheath fixing module, which simplifies the installation steps of the operator and reduces the area occupied by the two modules in the same area of ​​the tooling plate.

[0043] According to an embodiment of a wire harness sheath fixing module disclosed herein, the side wall of the outer shell 10 is provided with a limiting groove 15 communicating with the first cavity 11, and the limiting groove 15 is used to snap the inner shell 12 to the first position.

[0044] In specific implementation, the inner shell 12 is pressed down to the bottom of the outer shell 10, and then the inner shell 12 is slid toward the limiting groove 15 to engage the top end surface of the side wall of the inner shell 12 in the limiting groove 15, thereby fixing the inner shell 12 to the first position, so as to fix the assembled sheath using the first cavity 11.

[0045] Specifically, the outer shell 10 has a first sidewall and a second sidewall that extend along the length direction and are disposed opposite to each other, and at least one of the first sidewall and the second sidewall is recessed inward to form the limiting groove 15; and / or, the outer shell 10 has a third sidewall and a fourth sidewall that extend along the width direction and are disposed opposite to each other, and at least one of the third sidewall and the fourth sidewall is recessed inward to form the limiting groove 15;

[0046] By providing a limiting groove 15 in at least one of the first side wall, the second side wall, the third side wall, and the fourth side wall, the inner shell 12 is limited and positioned in the outer shell 10. By providing limiting grooves 15 in all of the first side wall, the second side wall, the third side wall, and the fourth side wall, it is convenient for operators to use the equipment and to select the appropriate position of the limiting groove 15 according to their personal habits, thereby improving the assembly efficiency of the operators.

[0047] According to one embodiment of a wire harness sheath fixing module disclosed herein, the inner housing 12 has a smaller dimension along the height direction than the first cavity 11. This allows the inner housing 12 to be snapped into the limiting groove 15, while the first cavity 11, positioned above the inner housing 12, provides space for fixing the assembled sheath.

[0048] According to an embodiment of a wire harness sheath fixing module disclosed herein, in a first position, the top end surface of the inner housing 12 is engaged with the limiting structure; in a second position, the top end surface of the inner housing 12 is disengaged from the limiting structure and flush with the top end surface of the outer housing 10.

[0049] In the first position, the first cavity 11 at the top of the inner housing 12 is used to fix the assembled sheath; in the second position, the top end surface of the inner housing 12 is flush with the top surface of the outer housing 10, so that the operator can use the second cavity 13 in the inner housing 12 to fix the inner core of the sheath.

[0050] According to an embodiment of a wire harness sheath fixing module disclosed herein, it further includes at least one support component, the support component including a support rod 16 and a limiting member 17 disposed on the support rod 16; the bottom wall of the outer shell 10 is provided with a through hole 18 for sleeved with the limiting rod, one end of the support rod 16 is connected to the bottom wall of the inner shell 12, and the limiting member 17 is located outside the outer shell 10 and contacts the bottom wall of the outer shell 10 when the inner shell 12 is switched to the second position.

[0051] By setting the support rod 16, the travel path of the inner housing 12 can be kept stable during the pressing of the inner housing 12. The top end surface of the inner housing 12 can be adjusted in the second position by the limiting member 17.

[0052] Specifically, the biasing member 14 is a compression spring, which is sleeved on the support rod 16 and disposed between the bottom wall of the inner housing 12 and the bottom wall of the outer housing 10.

[0053] By placing the compression spring on the support rod 16, a stable deformation path can be provided when the compression spring deforms, preventing the compression spring from bending radially outward during deformation.

[0054] More specifically, the bottom wall of the outer shell 10 is provided with a first positioning cavity 19 communicating with the through hole 18, and the connection between the first positioning cavity 19 and the through hole 18 forms a stepped surface 22; the bottom wall of the inner shell 12 is provided with a second positioning cavity, and the two ends of the compression spring are respectively provided in the first positioning cavity 19 and the second positioning cavity, and abut against the stepped surface 22 and the bottom wall of the second positioning cavity.
