The shape of the clamping hole 36 is adapted to the shape of the clamping block 34, so that the clamping block 34 can be smoothly clamped into the clamping hole 36 and the inserting portion 38 is limited in a direction parallel to the fixing surface 32. The direction parallel to the fixing surface 32 may be a plane formed in the front-rear up-down direction shown in fig. 1.

In some embodiments, the clip aperture 36 and the clip 34 limit each other in a direction parallel to the mounting surface 32, thereby limiting the interface 38 of the mounting plate 12 in a direction parallel to the mounting surface 32.

In this way, the insertion portion 38 can be restrained by the engagement hole 36 and the engagement block 34 restraining each other in a direction parallel to the fixing surface 32. Specifically, in one embodiment, the cross-sectional shape of the latch 34 along a direction parallel to the fixing surface 32 may include, but is not limited to, one of a circle, an ellipse, and a polygon, and the shape of the latch hole 36 is adapted to the shape of the latch 34.

In the embodiment shown in fig. 10, the shape of the clamping block 34 along the cross section parallel to the fixing surface 32 is trapezoidal, and the long side of the trapezoid faces the plugging portion 38, and the planar shape of the clamping hole 36 is trapezoidal and matches the shape of the clamping block 34. In the embodiment shown in fig. 1, when the connector 38 is mounted on the right module holder 100, the connector 38 may be mounted on the mounting plate 12 from the right side to the left side of the mounting plate 12, that is, the connector 38 may be mounted in a direction perpendicular to the fixing surface 32, so that the clip 34 is locked in the clip hole 36.

The connector 46 is fixed to the fixing plate 44, and the fixing plate 44 may be a circuit board, and the fixing plate 44 also serves to electrically connect the circuit board 42 and the connector 46 in addition to the fixing function.

In some embodiments, the distance between the mounting surface 47 of the latch 34 facing the inner wall of the latch hole 36 and the inner wall of the latch hole 36 is 0.1mm to 0.3mm.

In this way, the convenience of mounting the plug-in portion 38 is ensured while the fixing effect of the plug-in portion 38 is also ensured.

Specifically, if the distance between the fitting surface 47 of the fixture block 34 facing the fixture hole 36 and the inner wall of the fixture hole 36 is smaller than 0.1mm, the positioning accuracy requirement is high when the fixture block 34 and the fixture hole 36 are installed, and the connector 38 is inconvenient to install. If the distance between the mounting surface 47 of the clamping block 34 facing the clamping hole 36 and the inner wall of the clamping hole 36 is greater than 0.3mm, a relatively obvious shake occurs when the connector 38 is mounted to the mounting plate 12, and the fixing effect of the connector 38 is affected.

The distance between the assembly surface 47 of the clamping block 34 facing the clamping hole 36 and the inner wall of the clamping hole 36 is 0.1mm to 0.3mm, so that convenience in mounting the plugging portion 38 can be ensured, and meanwhile, the fixing effect of the plugging portion 38 is also ensured, and the plugging portion 38 is convenient and quick to mount.

Referring to FIG. 10, the distance D between the mounting surface 47 of the clip 34 facing the clip hole 36 and the inner wall of the clip hole 36 is 0.1mm to 0.3mm, that is, 0.1 mm.ltoreq.D.ltoreq.0.3 mm. In one example, D may be 0.1mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, or other values between 0.1mm and 0.3mm.

In some embodiments, the direction of removal of the connector portion 38 is perpendicular to the mounting surface 32.

Thus, the fitting of the plug-in portion 38 is convenient and quick.

Specifically, in fig. 1, when the connector 38 is mounted on the right module bracket 100, the connector 38 may be mounted from the right side to the left side of the mounting plate 12, and the mounting space of the connector 38 is limited by other components, so that the mounting of the connector 38 is convenient and quick.
