Abstract

The utility model belongs to the technical field of the lamp holder, and solves the problem of the prior lamp holder that the power-on and power-off operation during the on-off operation is very inconvenient, a power switch is connected on the tail end power cable of the lamp seat in series, the electric wire is pulled during the on-off operation,, the electrical connection part is loosened, and the problem of poor contact occurs. The switch lamp holder comprises a holder body (1) and a cover cap (2) arranged on the holder body (1). The switch lamp holder is characterized in that a switch (5) connected with a lamp base electrode (3) and a power supply terminal (4) in series is arranged inside the holder body (1) and the cover cap (2), the case (6) of the switch (5) is fixed on the back surface of the holder body (1), and an inverted hook (7) is arranged on the case (6). After the lamp holder is connected with the electric wire, the on-off operation can be realized on the lamp holder, the pulling of the electric wire can directly occur at the inverted hook (7), the pulling of the electric wire at the connecting terminal and the loosening are avoided, and bad contact or dropping out is avoided.

Description

The switch lamp socket

Technical field

The utility model belongs to technical field of lamp holders.

Background technology

Existing lamp socket is made of pedestal and cover cap, and the back side of pedestal is provided with binding post, and the cover cap fixed cap ought be inside with binding post on pedestal, gets an electric shock preventing.Its shortcoming is in use, and some lamp hangs above ceiling often and, and particularly hanging often will be gone to wall and go to carry out switching manipulation at pendent lamp above the dining table or the pendent lamp above desk when open and close, and is very inconvenient.If mains switch of serial connection tends to tear electric wire when switching manipulation on the tail end power line of lamp socket, cause electrical connection place to get loose, produce loose contact.

Summary of the invention

The utility model purpose is to provide has on/off control, the switch lamp socket that electric wire is connected firmly on a kind of pedestal.

For achieving the above object, described switch lamp socket comprises pedestal, be located at the cover cap on the pedestal, be provided with the switch that is serially connected between lamp base electrode and the power supply terminal in described pedestal and cover cap, the housing of described switch is fixed on the pedestal back side, is provided with barb on described housing.

Because the housing of switch is fixed on the pedestal back side, make electrode slice in the housing can directly be fixed on the electrode contact blade in the pedestal, be electrically connected and reliably be difficult for getting loose.The barb of housing can make power line at first be through in the barb, makes electric wire directly produce in overhead kick place and pulls, and has avoided electric wire to pull at the binding post place and produce and get loose, and causes loose contact or comes off.

Embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the utility model switch lamp socket is described in further detail.

Embodiment 1, as shown in Fig. 1,2,3,10, this is a switch lamp socket with knob switch, described switch lamp socket comprises pedestal 1, be located at the cover cap 2 on the pedestal 1, be provided with the switch 5 that is serially connected between lamp base electrode 3 and the power supply terminal 4 in described pedestal 1 and cover cap 2, the housing 6 of described switch 5 is fixed on pedestal 1 back side, is provided with barb 7 on described housing 6.Described housing 6 is provided with plug wire hole 8, and described power supply terminal 4 is the overhead kick shape and is arranged in the plug wire hole 8.Knob switch 5 is made of switch case 6, rotating shaft 18, center rotor 12, tongue piece 15, power supply terminal 4.

Described pedestal 1 is provided with two draw-in grooves 17, in draw-in groove 17, be provided with lamp base electrode 3, when the lamp with electrode card base is not shown when being installed in the pedestal 1, rotating a certain angle after electrode card base on the lamp inserts in the draw-in groove 17 just can contact with the lamp base electrode 3 in the draw-in groove 17, is fixed on simultaneously in the draw-in groove 17.

Be provided with rotating shaft 18, center rotor 12 in the described housing 6, rotating shaft 18 extends in a side of cover cap 2.Rotating shaft can make the knob switch break-make.Power line can vertically be inserted in the plug wire hole 8, the back side along housing 6 bends then, insert barb 7 below, because power line is in the bending of the back side of housing 6, and hang on the barb 7, therefore, in when, between power line and the housing 6 relative pullling being taken place when, can directly outwards not be drawn out of, so just improve the reliability that power line connects greatly on terminals from plug wire hole 8.

Power supply terminal 4 by closing-up on switch case 6, two terminals 13 couple together with two electrode slices, 3 usefulness electric wires respectively, the back terminal 13 that couples together is used closing-up with pedestal 1, tongue piece 15, terminal 13 use closing-up with pedestal 1, electrode thread tension disc 14, electrode slice 3 is inserted respectively in the middle of the draw-in groove of establishing in the pedestal 1 16 at this moment again.

Rotating shaft 18 can be fixed in the middle of switch case 6 and the pedestal 1, and oval center rotor 12 is housed in the rotating shaft 18.When passing bottom 9 in the pedestal 1 with rivet 10 with after switch case 6 riveteds become integral body, tongue piece 15 has certain distance with power supply terminal 4, drive oval center rotor 12 by rotating shaft 18 this moment, only contact and do not contact when oval center rotor 12 is in when horizontal with power supply terminal 4 with tongue piece 15, this moment, lamp socket was in off-state, not only contact with tongue piece 15 but also contact with power supply terminal 4 when vertical when oval center rotor 12 is in, this moment, lamp socket was in connection status.

Iron self-tapping screw 11 can seal in the integral body of rivet 10 after bottom 9, pedestal 1, switch case 6 riveteds, screw in then the hole post of establishing in the cover cap 2 not shown in the middle of, whole lamp socket is combined into an integral body.
