Abstract

A shelving system having a detached power supply apparatus includes at least a hollow vertical shelf rail, at least a bus bar inserted into the vertical shelf rail, and at least a detached power supply apparatus inserted in the vertical shelf rail and electrically connected to the bus bar. Each of the vertical shelf rails includes at least a punched hole, and two locating protrudes. Each of the bus bar includes a slot, and two current conductors. The slot includes a carrier surface, and a track abutting surface. Each of the detached power supply apparatus passes through the punched hole and is inserted between the carrier surface and the track abutting surface. Each of the detached power supply apparatus includes two push-in resilient ball head plungers, a receiving surface, an abutting surface, and two reeds. The abutting surface is engaging with the track abutting surface.

First claim

What is claimed is:

1. A detached power supply apparatus, comprising:
two push-in resilient ball head plungers spaced apart from each other;
a receiving surface for mounting the two push-in resilient ball head plungers;
an abutting surface opposite to the receiving surface; and
two reeds spaced apart from each other and locating on two sides of the receiving surface and the abutting surface, the elastic force direction of the two reeds being parallel to the receiving surface and the abutting surface, each of the two reeds comprising a limit groove.

2. The detached power supply apparatus as claimed in claim 1 , wherein the receiving surface, and the abutting surface together form a receiving chamber, the two push-in resilient ball head plungers are received in the receiving chamber.

3. The detached power supply apparatus as claimed in claim 2 , wherein the detached power supply apparatus further comprises a socket, and the socket is mounted in the receiving chamber.

4. The detached power supply apparatus as claimed in claim 1 , wherein the abutting surface comprises a slope along a direction perpendicular to the receiving surface.

5. The detached power supply apparatus as claimed in claim 1 , wherein the limit groove comprises an opening opened one end thereof, and a closed end disposed in the other end thereof.

6. A shelving system having a detached power supply apparatus, comprising:
at least a vertical shelf rail, each of the vertical shelf rail comprising at least a punched hole, and two locating protrudes provided on two opposite side walls of each of the punched hole;
at least a bus bar inserted into the vertical shelf rail, each of the bus bar comprising a body, and two current conductors spaced apart from each other, the body providing a slot opened thereon, the slot comprising a carrier plane configured for mounting the current conductors, and a track abutting surface opposite to the carrier plane; and
at least a detached power supply apparatus inserted in the vertical shelf rail and electrically connected to the bus bar, each of the detached power supply apparatus passing through the punched hole and being inserted between the carrier plane and the track abutting surface, each of the detached power supply apparatus comprising:
two push-in resilient ball head plungers spaced apart from each other;
a receiving surface for mounting the two push-in resilient ball head plungers;
an abutting surface opposite to the receiving surface; and
two reeds spaced apart from each other and locating on two sides of the receiving surface and the abutting surface, the elastic force direction of the two reeds being parallel to the receiving surface and the abutting surface, each of the two reeds comprising a limit groove, the abutting surface being engaging with the track abutting surface, each of the limit groove being clipped into the locating protrude.

7. The shelving system as claimed in claim 6 , wherein the two push-in resilient ball head plungers electrically connected to the two current conductors respectively.

8. The shelving system as claimed in claim 6 , wherein the abutting surface comprises a slope along a direction perpendicular to the receiving surface, the track abutting surface also comprises a slope along the direction perpendicular to the receiving surface.

9. The shelving system as claimed in claim 6 , wherein the maximum distance between the two reeds in the normal state is larger than the distance between the two side walls of the punched hole in which the locating protrudes 12 are disposed.

10. The shelving system as claimed in claim 6 , wherein the limit groove comprises an opening opened one end thereof, and a closed end disposed in the other end thereof, the locating protrudes are coupled to the closed end.
