However, due to the insertion of the second connecting member 200 and the first connecting member 100, the second limiting portion 210 is stationary relative to the first connecting member 100. Therefore, when the free end abuts against the second limiting portion 210 along the second direction Y, the second limiting portion 210 in contact with the first limiting portion 110 applies a reaction force to the first limiting portion 110, so as to compress and fix the cable through the first limiting portion 110, thereby realizing the first way of fixing the cable.

[0030] See also Figure 2 , Figure 3 , Figure 6 In some embodiments, the first limiting portion 110 includes a first connecting plate 111 and a first protrusion 112.

[0031] See also Figure 3 and Figure 6 In some embodiments, by setting the height of the first protrusion 112 protruding along the second direction Y, the clamping degree of the cable can be adjusted, and the clamping requirements of cables with different diameters can be met.

[0032] See also Figure 3 , Figure 4 and Figure 8 In some embodiments, along the first direction X, the other end of the first connecting plate 111 is connected to the first protrusion 112, so that the distance between the first protrusion 112 and the fixed end of the first connecting plate 111 is maximized, thereby increasing the swing amplitude of the first protrusion 112 along the first direction X when subjected to abutment force, and reducing the concentrated stress generated by the fixed end of the first connecting plate 111 due to the force swing, thereby increasing the service life of the product.

[0033] See also Figure 3 In some embodiments, the first protrusion 112 includes a first inclined surface 1121, and along the first direction X, the first inclined surface 1121 is located on the side of the first protrusion 112 close to the first connecting plate 111; there is a first inclination angle α between the first inclined surface 1121 and the first direction X, and the first inclination angle α ranges from 30° to 60°.

When the cable abuts against the fourth limiting portion 130, in the third direction Z, the fourth limiting portion 130 abuts against the fifth limiting portion 230, so that the fifth limiting portion 230 has a reverse force against the fourth limiting portion 130, so as to abut and fix the cable on the second inner wall 104 through the fourth limiting portion 130.

[0036] See also Figure 8 In some embodiments, the shell 120 has a fourth through groove 122, which is connected to the third through groove 103; the fourth limiting portion 130 is connected to the shell 120, and at least part of the fourth limiting portion 130 is located in the fourth through groove 122; along the third direction Z, the side of the fourth limiting portion 130 away from the third through groove 103 is configured to contact the fifth limiting portion 230.
