This figure is a simplified schematic diagram, which only illustrates the basics of the utility model in a schematic manner, so it only shows the structure related to the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

The wire 201 includes a sheath 2012 and a conductive wire 2011 disposed in the sheath 2012. The filling mechanism 100 includes a filling piece 10, a connecting assembly 20, a holding assembly 30 and a filling piece 2 40, and the filling piece 2 40 is detachably connected to the filling piece 10 through the connecting assembly 20, and when the filling piece 2 40 is connected to the filling piece 10, the filling piece 2 40 is held against the inner wall of the sheath 2012 through the holding assembly 30.

[0026] This embodiment is attached Figure 1 The ice maker wiring harness 1 with a gap filling structure shown in FIG. 1 is a state where the terminal 202 is injection molded. Figure 2 The ice maker wiring harness 1 with the gap filling structure shown in FIG. 1 is in a state where the terminal 202 is not molded.

[0027] The filler 10 is provided with a threading hole 11 for the conductive wire 2011 to pass through, and the filler 10 includes a supporting portion 12 and a connecting portion 13, and the threading hole 11 passes through the supporting portion 12 and the connecting portion 13. The side wall of the supporting portion 12 and the inner wall of the covering sleeve 2012 are supported against each other, and the supporting portion 12 blocks the end of the covering sleeve 2012 close to the terminal 202. The side wall of the connection part 13 is provided with a connection groove 131, and the side wall of the abutting part 12 is gradually reduced. When the covering sleeve 2012 is filled, the side wall of the abutting part 12 abuts against the inner wall of the covering sleeve 2012, and the diameter of the end of the abutting part 12 close to the connection part 13 is smaller than the diameter of the end of the abutting part 12 far from the connection part 13. In addition, the maximum diameter of the abutting part 12 of the filling piece 10 of this embodiment is slightly larger than the inner diameter of the covering sleeve 2012, and smaller than the outer diameter of the covering sleeve 2012, which does not affect the connection between the terminal 202 and the covering sleeve 2011. The outer wall of the abutting part 12 is inclined, and can abut against the covering sleeves 2012 with various inner diameters, and can adapt to the covering sleeves 2012 with various inner diameters, thereby improving the practicality of the ice maker wiring harness 1 with a gap filling structure.

[0028] The second filling member 40 is provided with a mounting hole 41 adapted to the connecting portion 13 , and the outer wall of the second filling member 40 is provided with abutment grooves 42 . Specifically, in this embodiment, the abutment grooves 42 are provided in pairs.

[0029] Specifically, in this embodiment, there are multiple filling pieces 40, and the outer diameters of the multiple filling pieces 40 are different. It can be understood that the mounting hole 41 of each filling piece 40 is adapted to the connecting portion 13 of the filling piece 10, and each filling piece 40 corresponds to a set of abutting components 30 and a set of connecting components 20. Filling pieces 40 with different outer diameters can correspond to the covering sleeves 2012 with different inner diameters. When used, the filling piece 40 with the corresponding outer diameter can be selected according to the inner diameter of the covering sleeve 2012. For the convenience of display, the accompanying drawings corresponding to this embodiment only show one filling piece 40.

[0030] The connection assembly 20 includes a connection block 21 disposed on the connection portion 13 and a connection block 22 disposed on the hole wall of the mounting hole 41. The connection block 21 is located in the connection groove 131. The connection block 21 is provided with a mounting groove 211. The connection block 22 is provided with an elastic pad 221. The connection block 22 is also provided with a connecting rod 222. The two ends of the connecting rod 222 are respectively connected to the connection block 22 and the elastic pad 221. The length of the connecting rod 222 is adapted to the length of the mounting groove 211. When the filler 240 is connected to the filler 10, force is applied to the elastic pad 221, so that the elastic pad 221 can be compressed, squeezed and deformed to pass through the mounting groove 211 and finally restore to its original state and be located above the connection block 21. At this time, the elastic pad 221 is abutted against the top wall of the connection block 21, and the connecting rod 222 is located in the mounting groove 211, so that the connection block 222 is limited to the connection block 21.

[0031] The abutting assembly 30 includes an abutting block 31 and a telescopic spring 32, one end of the telescopic spring 32 is fixedly connected to the groove wall of the abutting groove 42, and the other end of the telescopic spring 32 is fixedly connected to the abutting block 31. The abutting block 31 is elastically connected to the abutting groove 42 through the telescopic spring 32, and the abutting block 31 is slidably arranged in the abutting groove 42. When the filling member 2 40 is connected to the filling member 1 10, the abutting block 31 and the inner wall of the covering sleeve 2012 abut against each other. The abutting block 31 is provided with a limiting block 311, and the abutting groove 42 is provided with a limiting groove 421 adapted to the limiting block 311, and the limiting block 311 is slidably arranged in the limiting groove 421. The abutting block 31 is provided with a supporting surface 312, and the supporting surface 312 is an arc surface.

[0032] The working process of the ice maker wiring harness 1 with a gap filling structure provided by the utility model is as follows: first, the filling piece 10 and the filling piece 2 40 of the corresponding size are assembled, and the connecting block 22 on the filling piece 2 40 drives the elastic pad 221 to pass through the installation groove 211 on the connecting block 1 21, until the elastic pad 221 is located above the connecting block 1 21. Then, the assembled filling piece 10 and the filling piece 2 40 are installed into the covering sleeve 2012 along the inner wall of the covering sleeve 2012, and at the same time, a plurality of conductive wires 2011 in the covering sleeve 2012 are passed through the threading hole 11, and finally, the connecting part 13 of the filling piece 2 40 and the filling piece 10 are both located in the covering sleeve 2012, so that the outer wall of the abutting part 12 on the filling piece 10 and the opening of the covering sleeve 2012 are abutted against each other. When the filler 10 and the filler 2 40 are installed in the covering sleeve 2012, the abutment block 31 on the outer wall of the filler 2 40 abuts against the inner wall of the covering sleeve 2012, and the abutment block 31 is subjected to pressure and then applies pressure to the telescopic spring 32. The telescopic spring 32 is compressed and has a tendency to recover in the opposite direction. Therefore, the telescopic spring 32 exerts an outward force on the abutment block 31, thereby making the abutment block 31 and the inner wall of the covering sleeve 2012 press against each other, increasing the abutment force between the filler 2 40 and the inner wall of the covering sleeve 2012, so that during injection molding, the filler 10 and the filler 2 40 are not easy to loosen and affect the injection molding, thereby further improving the injection molding quality of the terminal 202.

[0033] Beneficial effect: During injection molding, the filler 10 is placed in the gap between the covering sleeve 2012 and the conductive wire 2011, the conductive wire 2011 outside the covering sleeve 2012 passes through the threading hole 11 for injection molding, and the abutting portion 12 blocks the end of the covering sleeve 2012 close to the terminal 202. Thus, the amount of injection liquid entering the covering sleeve 2012 during injection molding of the terminal 202 can be reduced, thereby improving the injection molding quality of the terminal 202.
