The first and second retainers 221 and 222 are defined as a first direction and a second direction perpendicular to the first direction, respectively, relative to the connecting body 21.

The first retaining member 221 and the second retaining member 222 are disposed opposite to each other from two opposite sides of the connecting body 21, that is, the first retaining member 221 and the second retaining member 222 are both disposed toward the connecting body 21, and enclose with the connecting body 21 to form an accommodating space 25 for accommodating at least part of the track 100. The receiving space 25 is substantially in a shape of a Chinese character 'tu', and includes a first space 251 and a second space 252 which are communicated with each other.

Correspondingly, the rail adapter 200 also includes a hollow connecting rod 28 that passes through the connecting hole 2115. The hollow connecting rod 28 is adapted to couple with an electrical device 300, for example, wires may be disposed within the hollow connecting rod 28 for electrically connecting the rail adapter 200 and the electrical device 300. By such an arrangement, the electrical device 300 can be easily coupled to the rail adaptor 200, and the mechanical connection and the electrical connection between the electrical device 300 and the rail adaptor 200 can be realized. In other embodiments, electrical device 300 may be directly connected to track adapter 200 without additional components interposed between electrical device 300 and track adapter 200. Alternatively, electrical system 400 may also include more connecting components between electrical device 300 and rail adapter 200, although the scope of the invention is not limited in this respect.

Referring to fig. 20 to 26, when the track adapter 200 of the electrical coupling device 300 needs to be connected to the track 100, the first retaining member 221 and the second retaining member 222 of the track adapter 200 extend into the first guide slot 121 and the second guide slot 122 of the track 100, so as to achieve the mechanical connection between the track adapter 200 and the track 100, and meanwhile, the power supply elastic piece 23 and the signal conductive piece 14 on the first retaining member 221 and the second retaining member 222 are elastically abutted to the power supply conductive piece 13 and the signal elastic piece 24 in the first guide slot 121 and the second guide slot 122, respectively, so as to achieve the electrical connection between the track adapter 200 and the track 100. The electrical system 400 is convenient and fast to install, and when the rail adapter 200 is connected to the rail 100, the rail adapter 200 and the rail 100 are partially overlapped in the thickness direction (i.e., the height direction) of the rail 100, so that the thickness of the electrical system 400 can be effectively reduced, and the occupied space of the electrical system 400 can be reduced.

When the rail adapter 200 slides to a position requiring illumination, an external force is applied to the first clamping member 221 and the second clamping member 222 of the rail adapter 200, so that the first clamping member 221 and the second clamping member 222 move oppositely, the locking part 261 on the first clamping member 221 and the second clamping member 222 is in locking fit with the locking part 2722 on the movable plate 272, the locking part 2722 is fixed in the locking groove, and the locking connection between the first clamping member 221 and the second clamping member 222 and the connecting body 21 is realized, so that the rail 100 is fixed in the accommodating space 25 of the rail adapter 200, the locking connection between the rail 100 and the rail adapter 200 is realized, and when the electrical equipment 300 rotates, the rail adapter 200 and the rail 100 fall off to cause potential safety hazards, and the safety of the electrical system 400 is improved. When the lighting position needs to be changed or the connection between the track adapter 200 and the track 100 needs to be released, an external force is applied to the pressing portions 271 of the unlocking assembly 27, so that the two pressing portions 271 move in opposite directions, the fastening portion 2722 slides out of the fastening groove, due to the existence of the yielding portions 2721, the fastening portion 261 and the fastening portion 2722 are released from the fastening connection, and the first clamping member 221 and the second clamping member 222 slide away from each other under the elastic force of the first elastic member 262, and return to the initial state. At this time, the external force is cancelled, and the pressing portion 271 returns to the original state by the elastic force of the second elastic member 273. In this way, the first catch 221 and the second catch 222 can be released from the locking connection with the connecting body 21, so that the rail 100 can move in the accommodating space 25 of the rail adapter 200, that is, the locking connection between the rail 100 and the rail adapter 200 is released, and the rail adapter 200 can slide relative to the rail 100.

Referring to fig. 27, an electrical system 400 according to another preferred embodiment of the present invention is shown, in which a lighting module is integrated in the track adapter 200, so as to avoid coupling the electrical device 300 to the track adapter 200, and reduce the occupied space of the electrical system 400. The lighting module may be a grille lamp or a linear lamp, etc., which is not limited in the present invention.

In summary, the track adapter 200, the track 100 and the electrical system 400 of the present invention have a simple structure, and the first and second retaining members 221 and 222 disposed opposite to each other can achieve mechanical connection and electrical connection with the track 100 from the outside of the track 100, so that the installation is simple and convenient, the connection stability between the track adapter 200 and the track 100 is improved, and meanwhile, the accommodating space 25 for partially accommodating the track 100 is formed on the track adapter 200, so that the track 100 and the track adapter 200 can be partially overlapped in the height direction, thereby effectively reducing the heights of the track 100 and the track adapter 200, and reducing the occupied space.

Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
