Abstract

The utility model relates to a lamp holder, particularly a dual-purpose lamp holder for both screw and bayonet lamp bulbs. The lamp holder needs to solve the problem of preventing fingers from electric shock caused by touching when the inner of the lamp holder is not provided with a lamp cap. The utility model is characterized in that the lower part of the positive negative connecting electricity sheet of the lamp holder is provided with an activating collateral flow carrier rod, the upper ends of a positive contact head and a bayonet negative contact head are provided with insulating washers, and the upper sides of the negative electric shock sheet and the negative connecting electricity sheet of a screw socket are provided with negative electric shock sheets. When the lamp holder is not arranged in the lamp cap, and the contact head does not have electricity, improving the safety performance of the lamp holder.

Description

Safety dual-purpose base for both screw and bayonet bulbs

The utility model relates to a kind of lamp socket, particularly screw socket, bayonet socket Two-purpose lampstand.

Spiral shell of the prior art, the bayonet socket Two-purpose lampstand is by housing, contact, spring, the electric shock sheet, power connecting sheet and end cap are formed, be provided with thread groove in the housing for the adapted screw cap, on thread groove, be shaped on simultaneously the bayonet slot of using for the adapted bayonet cap, case top is provided with positive and negative two electrode contacts by common bayonet cap form, and between these two electrode contacts, set up a screw cap contact, the touched electrode of screw cap side is by the metal threaded groove in the lampholder shell or electric shock sheet and the connection of lamp socket power connecting sheet, in a single day this lamp socket connects with the mains, contact in the lamp socket, metal threaded groove or electric shock sheet promptly become electrified body, because finger touches these electrified bodies easily, therefore potential unsafe factor need improve.

The purpose of this utility model is by the improvement to the prior art holder structure, provides a kind of the employing indirectly to reach the charged spiral shell of contact, bayonet socket dual-purpose safe lamp socket with alternately contacting indirectly again.

The utility model be with a limit contact in the lamp socket as spiral shell, the general positive contact of bayonet socket, another limit contact is as the bayonet socket negative contact terminal, middle contact is as the screw socket negative contact terminal; Under the anodal power connecting sheet of lamp socket, be provided with anodal active push rod, under the negative pole power connecting sheet, be provided with simultaneously the active push rod of negative pole, the cross section of anodal active push rod is "T"-shaped, the cross section of the active push rod of negative pole is circular-arc, the top of housing is pressed close to the inner walls place and is provided with the vertical through hole that matches with anodal active push rod and the active push rod cross section shape of negative pole respectively, and anodal active push rod and the active push rod of negative pole penetrate respectively among its corresponding through hole; Insulating washer has been installed in upper end in positive contact and bayonet socket negative contact terminal, and contact is not thrown off with the electric shock sheet when being subjected to the lamp holder pushing tow; A negative pole electric shock sheet is set above screw socket negative pole electric shock sheet and negative pole power connecting sheet, when the active push rod of negative pole is gone up negative pole power connecting sheet top, charged in order to conducting screw socket negative contact terminal.

Because this is practical when not packing lamp holder into, contact is not electriferous state, has safe and reliable advantage.

The explanation of accompanying drawing drawing: figure one is the assembling schematic diagram of spiral shell, bayonet socket dual-purpose safe lamp socket contact and electric shock sheet, power connecting sheet; Figure two is spiral shell, the active push rod of bayonet socket dual-purpose safe lamp socket and power connecting sheet assembling schematic diagram; Figure three is spiral shell, bayonet socket dual-purpose safe lampholder shell top assembling schematic diagram; 1 is anodal power connecting sheet, the 2nd among the above figure, anodal electric shock sheet, the 3rd, and insulating washer, the 4th, spring, the 5th, screw socket negative pole electric shock sheet, the 6th, negative pole electric shock sheet, the 7th, negative pole power connecting sheet, the 8th, bayonet socket negative pole electric shock sheet, the 9th, positive contact, the 10th, screw socket negative contact terminal, the 11st, bayonet socket negative contact terminal, the 12nd, anodal active push rod, the 13rd, the active push rod of negative pole, active push rod adopt ABS plastic or nylon is made, the 14th, spring leaf.

Realize that this practical best way is to install the top that two flat spring sheets are pressed in anodal active push rod and the active push rod of negative pole respectively at the top of housing, with keep positive and negative two root for activating collaterals push rods when lamp socket is not packed lamp holder into and the positive and negative polarities power connecting sheet be in contactless state, an end of spring leaf is screwed on the housing end face.

Claims

1, a kind of screw socket, bayonet socket Two-purpose lampstand are made up of housing, contact, spring, electric shock sheet, power connecting sheet and end cap, it is characterized in that an interior limit contact of lamp socket is as spiral shell, the general positive contact of bayonet socket, another limit contact is as the bayonet socket negative contact terminal, and middle contact is as the screw socket negative contact terminal; Under the anodal power connecting sheet of lamp socket, be provided with anodal active push rod, under the negative pole power connecting sheet, be provided with the active push rod of negative pole, the cross section of anodal active push rod is "T"-shaped, the cross section of the active push rod of negative pole is circular-arc, the top of housing is pressed close to the inner walls place and is provided with the vertical through hole that matches with anodal active push rod and the active push rod cross section shape of negative pole respectively, and anodal active push rod and the active push rod of negative pole penetrate respectively among its corresponding through hole; Insulating washer has been installed in upper end in positive contact and bayonet socket negative contact terminal; A negative pole electric shock sheet is set above screw socket negative pole electric shock sheet and negative pole power connecting sheet.

2, lamp socket according to claim 1 is characterized in that the top that two flat spring sheets are pressed in anodal active push rod and the active push rod of negative pole is respectively installed at the top of housing, and an end of spring leaf is screwed on the housing end face.
