Description
Technical field
The utility model relates to lighting field, relates in particular to a kind of end-cap assembly for LED fluorescent tube.
Background technology
When traditional fluorescent lamp pipe is adapted as LED fluorescent tube, the voltage 110V of civil power or 277V or higher voltage, can be directly connected to the end cap of LED fluorescent tube.In the time adopting the LED lamp tube structure of both-end energising, once a termination electricity of fluorescent tube, one end also will switch in addition, so cause in the time of mounted LED lamp pipe, installation personnel has the risk of electric shock.
U.S. Pat 8147091 discloses at a protruding-type elasticity end cap of the each increase of two end caps of LED fluorescent tube and has controlled inner safety switch.In the time that LED fluorescent tube is not yet installed, elasticity end cap is not pressed into the reed of safety switch so that disconnects the connection of end cap terminal and fluorescent tube internal wire.Only have in the time that LED fluorescent tube inserts the socket of light fixture, outstanding elasticity end cap can pressurized and be pressed into safety switch so that connect terminal and the fluorescent tube internal wire of end cap.So in the time that the socket of light fixture is inserted in one end of fluorescent tube, this end starts energising, but one end is owing to not yet inserting the socket of light fixture in addition, thus this end end cap terminal can not switch on, even the risk that the terminal of this end end cap of the free-hand contact of installation personnel does not also get an electric shock.But use the way of protruding-type elasticity end cap safety switch construction to have two defects.First defect is because old and while getting loose, socket cannot effectively be suppressed protruding-type elasticity end cap and then be pressed into safety switch, causes circuit loose contact when the socket of light fixture.The length dimension of the light fixture that second defect is fluorescent tube is not just the same, the length a little having a bit, and have shorter a little, if the fluorescent tube that has protruding-type elasticity end cap safety switch construction is inserted to long light fixture the inside, socket cannot effectively be suppressed protruding-type elasticity end cap safety switch construction, cause circuit loose contact, if instead light fixture is shorter, have the fluorescent tube of protruding-type elasticity end cap safety switch construction to put to enter at all.
PCT application WO2012/131547 discloses and has used the built-in spring of end cap that floats, and the terminal of external power supply is fixedly connected with the lamp body of LED fluorescent tube.While not yet installation, the terminal of external power supply is hidden in and floats in end cap, so installation personnel can not touch.When installation, floating end cover rim fluorescent tube axial compression, exposes terminal external power supply.This technology has solved first defect of above-mentioned protruding-type elastic safety switch, exactly when the socket of light fixture because old and while getting loose, also do not have the problem of circuit loose contact.But this technology still cannot solve the installation question causing because the length dimension of the light fixture of fluorescent tube differs, because the terminal of the LED fluorescent tube external power supply that this technology is used, to be fixedly connected with the lamp body of LED fluorescent tube, so the length of this fluorescent tube is fixed.This prior art also has another one defect, can't see the terminal of external power supply while installation exactly, must manual compacting end cap after, terminal just can expose, and installs both hands and must be anchored to the end cap on both sides, concerning the fluorescent tube of 120 centimeters is installed, very inconvenient.
Utility model content
Target of the present utility model is to provide a kind of LED tube end covers assembly, the security function that its realization must just be switched in the time that two of a fluorescent tube end cap is simultaneously inside lamp socket, ensure the danger that installation personnel does not get an electric shock when mounted, also solve the defect that prior art is used protruding-type elastic safety switch, increase security and applicability that LED fluorescent tube is installed simultaneously.
Target of the present utility model is realized by a kind of LED tube end covers assembly, it comprises end cap shell, elastomer and end cap connected structure, on the outside bottom surface of end cap shell, there is more than one power supply terminal, elastomer is positioned at the inner chamber of end cap shell, end cap shell telescopically is socketed on one end of end cap connected structure, the other end of end cap connected structure is for engaging with the lamp body of LED fluorescent tube, on the bottom surface of the end cap abutting end of end cap connected structure, there is more than one power connection, in an end in contact of elastomer power connection and power supply terminal in the time being stressed state, in the time not being stressed state, between power connection and one end of power supply terminal, there is interval at elastomer.
Preferably, end cap connected structure also comprises that one with screwing, the upper semisection of the close spiral shell head of screw does not have screw thread, in the housing of end cap shell, have one above along end cap enclosure axis to elongated slot, wherein screw is arranged in elongated slot, and the lower semisection of screw is bonded on end cap shell on the end cap abutting end of end cap connected structure.
Preferably, power connection be can elastic telescopic column power connection.
Further preferably, the axial stretching length of power connection is between 1-10mm.
Further preferably, power connection has built-in spring.
Preferably, elastomer in the time not being stressed state the interval between power connection and one end of power supply terminal between 2-10mm.
The utility model end-cap assembly is in the time being installed on LED fluorescent tube, when along fluorescent tube axial compression end cap shell, cause elastomer compression, thereby cause power supply terminal to touch power connection and by the current lead-through of lamp socket to LED fluorescent tube, in the time that external pressure is eliminated, elastomer is oppositely released end cap shell, makes power supply terminal and power connection separately reach the effect of power-off.The LED fluorescent tube with the utility model end-cap assembly, before being installed in light fixture, end-cap assembly can not be switched on, thereby provides suitable electrical shock protection safety for the installation personnel of LED fluorescent tube.
