Track lamp with elastically biased convex power connector
View Patent ↗A track lamp includes a track having a power transmission bar, and an electrical connection device in electrical contact with the track. The electrical connection device includes a substrate, a power supply structure plugged and fixed on the substrate, and an elastic member arranged between the substrate and the power supply structure. The power supply structure features a convex portion in electrical contact with the power transmission bar. The elastic member is configured to bias the convex portion and the power transmission bar against each other, such that the convex portion and the power transmission bar are kept in contact with each other.
1 . A track lamp, comprising:
a track with a power transmission bar; and
an electrical connection device in electrical contact with the track and comprising a substrate, a power supply structure plugged and fixed on the substrate and having a convex portion in electrical contact with the power transmission bar, and an elastic member arranged between the substrate and the power supply structure,
wherein the power supply structure comprises a horizontally extending support plate and connecting parts respectively vertically connected to two ends of the support plate, to form an inverted U shape, and the convex portion is arranged on a side of the support plate facing the power transmission bar; and
wherein the elastic member is configured to bias the convex portion and the power transmission bar against and in contact with each other.
2 . The track lamp according to claim 1 , wherein the elastic member and the substrate are integrally formed.
3 . The track lamp according to claim 1 , wherein the elastic member forms an arch shape between the substrate and the support plate, a highest point of the elastic member abutting against a position of a corresponding convex portion on the support plate.
4 . The track lamp according to claim 1 , further comprising an abutting surface provided on a side of the elastic member away from the substrate, and the abutting surface is in contact with the support plate.
5 . The track lamp according to claim 1 , further comprising a boss formed in the substrate; and a conductive groove provided in the track, wherein the elastic member extends from the boss in a direction away from the substrate, the power transmission bar is arranged at a bottom of the conductive groove, and the boss and the elastic member extend into the conductive groove to make the convex portion abut against the power transmission bar.
6 . The track lamp according to claim 1 , further comprising through holes formed in the substrate, with the connecting parts passing through the through holes.
7 . The track lamp according to claim 6 , wherein the elastic member is located between the two through holes in a length direction of the track lamp.
8 . The track lamp according to claim 1 ,
further comprises a shell; a light-emitting component accommodated in the shell; and a circuit board electrically provided in the electrical connection device and connected to the light-emitting component, wherein
an end of the power supply structure away from the convex portion passes through the substrate and is electrically connected to the circuit board.
9 . The track lamp according to claim 8 , further comprising a flexible wire connecting the circuit board and the light emitting component.
