Abstract

The invention relates to a shelf electrical supply system, comprising electrical supply guide track fixedly connected to a shelf; electrical input part connected to the electrical supply guide track; electrical component disposed on the electrical supply guide track; the electrical supply guide track comprises track groove, metal guide track disposed in the track groove, and the electrical input part is electrically connected to one end of the metal guide track; the electrical component comprises magnet block and conductive contact arranged around the magnet block, and when the electrical component is disposed on the electrical supply guide track, the magnet block is attracted to the metal guide track and the conductive contact is in contact with the metal guide track. The system has simple structure, convenient assembly and better personalized design.

First claim

What is claimed is:

1. A shelf electrical supply system, comprising:
electrical supply guide track ( 1 ) fixedly connected to a shelf;
electrical input part ( 2 ) connected to the electrical supply guide track ( 1 );
electrical component ( 3 ) disposed on the electrical supply guide track ( 1 ); the electrical supply guide track ( 1 ) comprises track groove ( 11 ), metal guide track ( 12 ) disposed in the track groove ( 11 ), and the electrical input part ( 2 ) is electrically connected to one end of the metal guide track ( 12 );
the electrical component ( 3 ) comprises magnet block ( 31 ) and conductive contact ( 32 ) arranged adjacent to the magnet block ( 31 ), and when the electrical component ( 3 ) is disposed on the electrical supply guide track ( 1 ), the magnet block ( 31 ) is attracted to the metal guide track ( 12 ) and the conductive contact ( 32 ) is in contact with the metal guide track ( 12 ); wherein the electrical component ( 3 ) further comprises conductive plate ( 33 ) and electrical plug ( 34 ), and the conductive plate ( 33 ) is provided with a through hole ( 331 ) for the magnet block ( 31 ) to pass through, the conductive contact ( 32 ) is disposed on the conductive plate ( 33 ) and protrudes from the conductive plate ( 33 ), and the electrical plug ( 34 ) is electrically connected to the conductive plate ( 33 ) through wire ( 37 ).

2. The shelf electrical supply system as claimed in claim 1 , wherein the track groove ( 11 ) of the electrical supply guide track ( 1 ) is made of non-conductive material, and the lower side of the track groove ( 11 ) is fixedly connected to the shelf by soft magnet ( 4 ), and the soft magnet ( 4 ) is bonded to the lower side of the track groove ( 11 ).

3. The shelf electrical supply system as claimed in claim 1 , wherein the track groove ( 11 ) of the electrical supply guide track ( 1 ) is made of non-conductive material, and the lower side of the track groove ( 11 ) is fixedly connected to the shelf by double-sided tape.

4. The shelf electrical supply system as claimed in claim 1 , wherein there are four conductive contacts ( 32 ), divided into two groups and arranged on both sides of the magnet block ( 31 ), and the conductive contact ( 32 ) on the same side is of the same grade.

5. The shelf electrical supply system as claimed in claim 1 , wherein the metal guide track ( 12 ) is connected to the track groove ( 11 ) by double-sided tape.

6. The shelf electrical supply system as claimed in claim 1 , wherein the electrical component ( 3 ) further comprises a cover plate ( 35 ) between the metal guide track ( 12 ) and a conductive plate ( 33 ) and a bottom case ( 36 ) disposed on the cover plate ( 35 ), the cover plate ( 35 ) is provided with a first hole ( 351 ) and a second hole ( 352 ) where for the magnet block ( 31 ) and the conductive contact ( 32 ) are extending from respectively;
the inner wall of the bottom case ( 36 ) is formed with a hollow column ( 361 ) along a direction perpendicular to the electrical supply guide track ( 1 ), and the two opposing sidewalls ( 362 ) of the bottom case ( 36 ) which is parallel to the extending direction of the electrical supply guide track ( 1 ) extend downwardly to form a clamping part ( 363 );
in the assembly state, the hollow column ( 361 ) passes through the through hole ( 331 ) and the first hole ( 351 ) successively and is sleeved around the periphery of the magnet block ( 31 ), and the clamping part ( 363 ) is connected with the two outer sidewalls ( 13 ) of the track groove ( 11 ) which is in the extension direction by clamping.

7. The shelf electrical supply system as claimed in claim 6 , wherein a cylinder ( 364 ) formed by extending in the same direction as the hollow column ( 361 ) is formed in the hollow column ( 361 ), and the magnet block ( 31 ) is provided with a mounting hole ( 312 ), and the cylinder ( 364 ) is extended into the mounting hole ( 312 ) in the assembly state.

8. The shelf electrical supply system as claimed in claim 1 , wherein the electrical input part ( 2 ) comprises a bottom plate ( 21 ), a housing ( 23 ) which is arranged above the bottom plate ( 21 ) and is enclosed with the bottom plate ( 21 ) to form a holding cavity, and a guide line ( 24 ) extending into the holding cavity from one side of the housing ( 23 ) and connected to the metal guide track ( 12 ), and a plug ( 22 ) that is connected to the other end of the guide line ( 24 ).

9. The shelf electrical supply system as claimed in claim 8 , wherein the housing ( 23 ) is internally provided with a blind hole ( 25 ), and the bottom plate ( 21 ) is located below the track groove ( 11 ) and connected with the blind hole ( 25 ) by screw ( 26 ) which passes through the track groove ( 11 ) and the metal guide track ( 12 ) successively.
