Shift-out lamp holder switch

Abstract

The invention discloses a shift-out lamp holder switch and relates to the technical field of LEDs (light-emitting diode). The shift-out lamp holder switch comprises a lamp holder; one of two surfaces of the lamp holder is provided with pins; the shift-out lamp holder switch also comprises a casing pipe; the casing pipe is vertically arranged on the other surface of the lamp holder; the other surface of the lamp holder is also vertically provided with two symmetric moving contacts; an inner pipe is arranged in the casing pipe; two symmetric grooves arranged along the direction of the inner pipe are formed in the outer wall of the inner pipe; contact points of the two moving contacts respectively abut on the bottom parts of the two grooves; static contacts are respectively arranged in the two grooves; each static contact is arranged at one side, near the lamp holder, of a point at which the contact point of each moving contact is in contact with the corresponding groove; the static contacts are not in contact with the contact points of the moving contacts. By adopting the structure of the shift-out lamp holder switch disclosed by the invention, the electric shock hidden danger caused by the fact that operating personnel touches the pins during an installation process is avoided, and the safety is high; moreover, the shift-out lamp holder switch disclosed by the invention has the advantages that the structure is simple; manual testing is not needed; while the production efficiency is improved, the cost is reduced.

Description

technical field [0001] The invention relates to an LED technology, in particular to a removable lamp head switch. Background technique [0002] Due to the particularity of the power supply method and installation method of the double-ended LED fluorescent tube, if the operator holds one end and connects the other end to the electrode, there is a possibility of electric shock, and the operator has potential safety hazards. [0003] The solutions in the prior art mostly adopt adding circuits on the power supply to reduce the leakage current, but this technical solution has the following defects: [0004] 1. The circuit is too complicated, resulting in a large power supply; [0005] 2. Increasing the circuit will increase the cost; [0006] 3. The detection method is more complicated, and the corresponding lamp holder needs to be made. The lamp holder is removed from one end of the lamp holder, and a non-inductive 500Ω resistor is connected between an accessible pin and the g...
