The fixing button 23 is at least partially disposed in the mounting cavity 211, and the fixing button 23 is configured to be detachably connected to the power rail 1 to enable fixing and movement of the adapter 2. Under the condition that external force acts on the fixing buckle 23 by a user, the fixing buckle 23 is contracted into the body 21, the adapter 2 is separated from the power rail 1, and the adapter 2 can be driven to move along the length direction N1 relative to the power rail 1, so that the relative position of the adapter 2 and the power rail 1 is changed. After the user removes the external force, the fixing buckle 23 protrudes out of the body 21, and the fixing buckle 23 can be clamped with the power rail 1, so that the positions of the adapter 2 and the power rail 1 can be relatively fixed.

At this time, the clamping member 232 is separated from the first limiting portion 1131, so as to avoid the clamping member 232 from interfering with the installation of the adapter 2 and the power rail 1. After the installation of the adapter 2 and the power rail 1 is completed, the external force is removed, the elastic piece 233 is restored to deform, the restoring force of the elastic piece 233 drives the clamping piece 232 to extend out of the body 21, and the clamping piece 232 is clamped into the first limiting portion 1131 of the cover plate 113, so that the adapter 2 and the power rail 1 are fixed.

The principle of the fixing button 23 will be explained with reference to fig. 1 to 8:

In the case of the adapter 2 to be mounted to the contact cavity 111 of the power rail 1, the user external force acts on the key 231, so that the key 231 moves leftwards in the width direction N2, the clamping member 232 moves upwards in the thickness direction N3 under the abutment of the first inclined surface 2311, and the clamping member 232 is retracted into the body 21, at this time, the body 21 has a flat lower surface, so that the adapter 2 is mounted conveniently. Then, the second support 222 of the conductor 22 is inserted into the insertion port 112 along the width direction N2, so that the contact pin 2221 in the second support 222 is connected to the conductive element 12. Then, the user removes the external force, and the elastic member 233 rebounds, so that the bottom end of the clamping member 232 is clamped into the first limiting portion 1131, and thus the assembly of the adapter 2 and the power rail 1 is realized.

When the relative position of the adapter 2 in the longitudinal direction of the power rail 1 is adjusted, the initial state is that the engaging piece 232 is engaged in the first limiting portion 1131. Then, the key 231 is moved to the left along the width direction N2 by the external force of the user, so that the end with the larger thickness of the first inclined surface 2311 abuts against the clamping member 232, the clamping member 232 is retracted into the body 21 upwards along the thickness direction N3, the clamping member 232 is separated from the first limiting portion 1131 of the power rail 1, the lower surface of the body 21 is flat, and therefore movement of the adapter 2 along the length direction N1 can be achieved, and at this time, the elastic member 233 is deformed under pressure. After the adapter 2 moves in place along the length direction N1, the user removes the external force, and the elastic piece 233 automatically rebounds to drive the clamping piece 232 to automatically reset along the thickness direction N3, and the bottom of the clamping piece 232 stretches out the lower surface of the body 21 again, so that the clamping piece 232 is clamped in the first limiting part 1131, and the relative position of the adapter 2 on the power rail 1 is fixed.

The foregoing description is only of the preferred embodiments of the present utility model, and is not intended to limit the scope of the present utility model.
