Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of embodiment of switching regulator Anti-electroshock LED tube of the present utility model;
Fig. 2 is the longitudinal cutting structure figure of a kind of embodiment of switching regulator Anti-electroshock LED tube of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as restriction of the present utility model.
As shown in Figures 1 and 2, a kind of switching regulator Anti-electroshock LED tube, comprising:
Enclosing cover 3, its capping has a through hole,
Lamp base 1 is fixed on the lateral surface of enclosing cover 3, for connecting external circuit;
Outer cover 6 is connected to the lower limb of enclosing cover 3, is provided with draw-in groove in it, and pcb board 7 arranges and is fixed in draw-in groove is convenient to connection circuit;
Shell fragment 4 top is connected with the medial surface of enclosing cover 3, and is communicated with lamp base 1 one_to_one corresponding, and bottom is near PCB but be not in contact with each other mutually, is communicated with the circuit between lamp base 1 and pcb board 7 for shell fragment 4 when contacting pcb board 7;
Button 2 is a cylinder, and the limited part of boss structure is arranged at bottom, and button passes from the through hole of the medial surface of enclosing cover 3, and button 2 is extrusion elastic 4 under force, makes shell fragment 4 contact with pcb board 7 and connect circuit;
Spring 5 upper end is connected with button 2, the top of lower end connecting PCB board 7, for being separated shell fragment 4 and pcb board 7 under normal conditions, makes push-button reset.
When LED lamp tube do not load in tube stand or be not subject to External Force Acting on button 2, contained spring 5 relies on elastic force button 2 toward extrapolation, shell fragment 4 is separated with PCB simultaneously, internal circuit is not communicated with, can not occur in operation, because carelessness causes electric shock accidents, to have ensured safety.
When LED lamp tube loads inside tube stand completely, the shift knob 2 exceeding enclosing cover 3 extrudes to shell fragment 4 under the effect of external force, makes shell fragment 4 touch pcb board 7 under the effect being subject to power, and lamp base 1 and pcb board 7 are connected, and internal electric is communicated with.Reach lamp base 1 and can touch pcb board 7, button 2 need exceed enclosing cover 3 lateral surface more than height 3.5mm, not higher than lamp base 1.
