The utility model comprises a porcelain casing, a mouth ring and a contact piece which are arranged on the porcelain casing used for contacting with a lamp cap, an insulating washer which is installed on the top end of the porcelain casing and a metal supporting frame which is used for clamping with the insulating washer together with the porcelain casing; the top end of the porcelain casing is provided with a wire groove; an opening of the wire groove is arranged on the insulating washer corresponding to the position of the wire groove; the top end of the porcelain casing is provided with a lug boss; a cutting groove which can be sheathed on the lug boss is arranged on the corresponding insulating washer. When assembled, the utility model has the advantages of convenience, preservation of the original insulation effect and simple structure.
Description
The utility model relates to a kind of lamp socket of improveing insulation spacer.
The existing lamp socket that is used to install bulb, especially for powerful bulb is installed, the structure of its lamp socket not only will be considered fixation, also will consider security appliance.Its structural design comprises porcelain shell 1, is arranged on mouth circle 2 and center contact chip 3 in the porcelain shell.Mouth circle and center contact chip are electrode, are to be used for contacting with the lamp holder of bulb.On porcelain shell top insulation spacer 13 Hes are set, insulation spacer is provided with the metallic support 21 that is fixed on porcelain shell top, and this metallic support and porcelain shell are fixing by screw 22, common clamping insulation spacer.Be provided with wire casing 15 on porcelain shell top, be provided with the connector 4,5 that Qi Kouquan and center contact chip are connected with electric wire in the wire casing, as rivet or screw.Metallic support bears the total weight of lamp socket and bulb, and is less because of distance between the electric wire metal end in itself and the wire casing, is easy to generate discharge.The setting of insulation spacer is to increase the creepage distance between metallic support and the electric wire metal end, in order to avoid human body touch lamp decoration outer casing electrification causes the generation of electric shock accidents.Existing holder structure exists following defective when the assembling insulation spacer: the line hole 17 that is provided with on this insulation spacer is circular hole, and this design exists a problem, and the circular hole that electric wire need pass pad could be contained in pad on the porcelain shell.Because the termination that electric wire need connect has been connected with the ring-type electric connection terminal in advance, this electric connection terminal is greater than the line hole, and electric wire can only be worn cable-through hole from the other end, and is when lamp socket need connect long electric wire, just very inconvenient.Moreover in assembling during lamp socket, because insulation spacer can't fix on porcelain shell top, if during with porcelain shell reversing operation, pad can drop from the porcelain shell.In addition, insulation spacer also can be torn because of the electric wire that passes wherein, and the location is inaccurate, and these phenomenons all can influence assembly manipulation.
It is a kind of under the condition that does not influence the insulation spacer insulation effect that the purpose of this utility model is to provide, and makes assembly manipulation easy, and wiring simply improves the lamp socket of insulation spacer.
For realizing the purpose of this utility model, the lamp socket of described improvement insulation spacer comprises the porcelain shell, be arranged on the mouth circle and the center contact chip that are used in the porcelain shell contacting with lamp holder, be installed in the insulation spacer on porcelain shell top, with the metallic support of the common clamping insulation spacer of porcelain shell, be provided with wire casing on porcelain shell top, corresponding wire casing position is provided with the wire casing mouth on described insulation spacer, be provided with boss on porcelain shell top, correspondence is being provided with the grooving that can be enclosed within on the described boss on the described insulation spacer.
The drawing of accompanying drawing is described as follows:
Fig. 1 is existing lamp holder assembling structure schematic diagram.
The structure chart that Fig. 2 assembles for Fig. 1.
Fig. 3 is the assembly structure schematic diagram of the utility model improvement insulation spacer.
The structure chart that Fig. 4 assembles for Fig. 3.
Fig. 5 is the assembly structure schematic diagram of the another kind of improvement of the utility model insulation spacer.
The structure chart that Fig. 6 assembles for Fig. 5.
Below in conjunction with accompanying drawing, the embodiment that the utility model is improved the lamp socket of insulation spacer is described in further detail:
As shown in Fig. 3,4, the lamp socket of improvement insulation spacer described in the utility model comprises porcelain shell 1, mouthful circle 2, center contact chip 3, insulation spacer 13, metallic support 21, the wire casing 15 on porcelain shell top, rivet 4,5.Mouth circle 2 and center contact chip 3 are fixed in the cavity of porcelain shell bottom by rivet 4,5, do not look out among the figure.Corresponding wire casing position is provided with wire casing mouth 24 on described insulation spacer, and when the ring-type electric connection terminal 6 of electric wire termination was fixed in the wire casing by rivet, electric wire can be put into wire casing mouth bottom from the side of insulation spacer, has avoided original perforation procedure.Be provided with three boss 18 on porcelain shell top, correspondence is being provided with three groovings 14 that can be enclosed within on the described boss on the described insulation spacer, and it is the opening shape that two groovings are wherein arranged, and one is poroid.When this insulation spacer is installed in porcelain shell top, three groovings snap in boss, insulation spacer is fixed on porcelain shell top, and this moment, electric wire can be put into insulation spacer, insulation spacer can not be subjected to tearing of external force like this, if with screw 22 pass on porcelain shell, the insulation spacer the hole be fixed in the screw on the metallic support, assembly manipulation is easy.
As shown in Fig. 6,5, the lamp socket of this improvement insulation spacer and above-mentioned difference are that mouthful circle 2 and center contact chip 3 are to be fixed in the cavity of porcelain shell bottom by screw 7,8 and lug plate 9,10, do not look out among the figure.Lug plate is installed in the wire casing 15, on screw and screw 11,12 are arranged so that be connected with electric wire.Porcelain shell top is provided with two boss 20, corresponding two groovings 23,16 that can be enclosed within on the described boss that are provided with on described insulation spacer 13.
The utility model is than prior art, owing to be provided with grooving, line at insulation spacer and porcelain shell top Notch, boss in when assembling, has convenient and swiftly, has kept the insulation effect of original structure, and is simple in structure Advantage.
