[0041] See also Figures 1 to 4, the cable assembly 20 includes a cable 201, a terminal 202 and a shielding ring 203. The embodiment of the present application provides a preparation device 10 for a cable assembly, and the preparation device 10 for the cable assembly includes a first base 110, a second base 120, a first crimping mechanism 200 and a second crimping mechanism 300. The first base 110 and the second base 120 are arranged relatively to each other along a first direction X, and can move relatively to each other along the first direction X. The first crimping mechanism 200 includes a first crimping member 210 and a second crimping member 220, the first crimping member 210 is arranged on a side of the first base 110 facing the second base 120, and the second crimping member 220 is arranged on a side of the second base 120 facing the first base 110, along the first direction X, the projection of the first crimping member 210 and the projection of the second crimping member 220 at least partially overlap, and the first crimping member 210 and the second crimping member 220 cooperate to crimp the terminal 202 on the cable 201. The second crimping mechanism 300 includes a third crimping member 310 and a fourth crimping member 320. The third crimping member 310 is disposed on a side of the first base 110 facing the second base 120, and the fourth crimping member 320 is disposed on a side of the second base 120 facing the first base 110. Along the first direction X, the projection of the third crimping member 310 and the projection of the fourth crimping member 320 at least partially overlap. The third crimping member 310 and the fourth crimping member 320 cooperate to crimp the shielding ring 203 on the cable 201. The first crimping member 210 and the third crimping member 310 are spaced apart along the second direction Y.

[0042] In some embodiments, the first direction X is perpendicular to the second direction Y.

[0043] See also Figure 5 , multiple cable assemblies 20 can be combined into a wiring harness through a fixing member 204, and the wiring harness can be used to connect with a device such as a motor. The fixing member 204 is arranged on the outer wall of the motor housing 301, and a fixing column 302 is arranged in the motor. The terminal 202 penetrates the motor housing 301 and is sleeved on the fixing column 302; a sealing ring 205 is arranged between the shielding ring 203 and the motor housing 301 for waterproofing the motor. If the distance between the terminal 202 and the shielding ring 203 is too short, the terminal 202 cannot be sleeved on the fixing column 302, making it difficult to install the wiring harness. If the distance between the terminal 202 and the shielding ring 203 is too long, the terminal 202 is sleeved on the fixing column 302, which will cause a large gap between the fixing member 204 and the motor housing 301, and the sealing ring 205 cannot play a good sealing effect. External water vapor entering the motor is likely to cause an internal short circuit of the motor, thereby causing thermal runaway and affecting the safety of the motor.

The third crimping member 310 and the fourth crimping member 320 of the second crimping mechanism 300 are respectively arranged on the first base 110 and the second base 120. Along the first direction X, the projection of the third crimping member 310 and the projection of the fourth crimping member 320 at least partially overlap, so that the third crimping member 310 and the fourth crimping member 320 can be close to each other to achieve crimping of the shielding ring 203. The first crimping member 210 and the third crimping member 310 are spaced along the second direction Y, and the second crimping member 220 and the fourth crimping member 320 are spaced along the second direction Y, so that the distance between the terminal 202 and the shielding ring 203 on the cable 201 after crimping can be fixed, thereby improving the distance accuracy between the terminal 202 and the shielding ring 203, reducing the possibility of the above-mentioned problem, and facilitating the subsequent installation of the cable assembly 20.
