Through the staggered arrangement of the first wire clamping blocks 122 and the second wire clamping blocks 123, the first wire clamping blocks 122 and the second wire clamping blocks 123 squeeze the wire harness, so that the wire harness is interference-fitted with the cable trough 121, the wire harness is fixed, the potential risks caused by the free state of the wire harness are avoided, and the stability and reliability of the device are improved.

[0040] In some embodiments, the module upper cover assembly further includes a line card 2, the reinforcement portion 12 is provided with a plurality of mounting portions 14 on both sides of the cable slot 121, the mounting portion 14 is formed by the reinforcement portion 12 protruding downward, the mounting portion 14 is provided with a mounting hole 141, the mounting hole 141 is a blind hole, and mounting columns 221 matching the mounting hole 141 are respectively provided at both ends of the line card 2.

When there are fewer wire harnesses or the wire diameter is smaller, the wire harnesses are fixed by the line card 2 to avoid the potential risks brought by the free state of the wire harnesses, thereby improving the stability and reliability of the device.

[0041] In some embodiments, the line card 2 includes a clamping fold 21, two installation folds 22 and two reinforcement folds 23; the two installation folds 22 are respectively arranged at the two ends of the clamping fold 21, and the installation column 221 is arranged on the installation fold 22; the reinforcement fold 23 is located at one end of the installation fold 22 away from the clamping fold 21, and the reinforcement fold 23 and the clamping fold 21 are located on the same side of the installation fold 22.

When there are fewer wire harnesses or the wire diameter is small, the wire harness is fixed by the wire clamp 2 to avoid the potential risks brought by the free state of the wire harness and improve the stability and reliability of the device.
