Abstract

The utility model relates to a current of lamp cluster bulb group switches on device mainly is equipped with the combination piece in the inside of lamp stand, can directly gomphosis in the bottom of the base of a lamp, and the lower part that should combine the piece has set firmly a U type conducting strip in addition, makes the base of a lamp penetrate the lamp stand after, and the both sides edge of U type sheetmetal can press to touch conductive terminal's seat, makes bulb part form parallelly connected electrically conductive structure, avoids its damage, is convenient for switch on.

Description

A kind of current lead-through device of lamp series bulb group

The utility model relates to the light fixture class, particularly a kind of current lead-through device of lamp series bulb group.

Between each bulb group of general Christmans light string, normally connect with series system, in case the bulb in the lamp string damages, then form and open circuit, whole lamp string just can't be shinny; Sometimes utilize combination in parallel, shortcoming when overcoming above-mentioned series connection, be to be equipped with a Y type piece in addition in lamp socket inside, be placed with a conducting post again on top, make lamp base of a fruit combination after, location Y type piece and conducting post, and be connected with the conducting terminal of both sides, this structure is made inconvenience, increases the complexity of assembling, and the conducting strip of conducting post both sides is easily because of bending causes loose contact, or even can't contact energising.

The purpose of this utility model is exactly the shortcoming that exists at above-mentioned general Christmans light string, and a kind of current lead-through device of lamp series bulb group is provided, and makes manufacturing easy, and assembling is simple, and the conducting contact is good.

Technical conceive of the present utility model:

According to the purpose of this utility model, a kind of current lead-through device of lamp series bulb group is provided, it mainly is to be provided with combined block in the inside of lamp socket, can directly be embedded in the bottom of the lamp base of a fruit, the bottom of this combined block is installed with U type conducting strip in addition, after making the lamp base of a fruit penetrate lamp socket, the both side edges of U type conducting strip is to press the seat portion that touches in conducting terminal, makes bulb portion divide the structure that forms parallel conductance.

Accompanying drawings structure of the present utility model and embodiment:

Fig. 1 is a perspective exploded view of the present utility model.

Fig. 2 is a combination cross-sectional schematic of the present utility model.

Fig. 3 is another embodiment perspective exploded view of the present utility model.

Fig. 4 makes up cross-sectional schematic for another embodiment of the present utility model.

1 is that the lamp base of a fruit, 11 is that slot, 2 is that bulb, 21 is that conductive filament, 3 is that lamp socket, 4 is that conducting terminal, 41 is that electric wire, 5 is that combined block, 51 is that flange, 52 is that U type conducting strip, 6 is that sealing block, 61 is that arc groove, 62 is a U type conducting strip.

Shown in accompanying drawing 1 and accompanying drawing 2, the utility model is made of the lamp base of a fruit 1, bulb 2, lamp socket 3, conducting terminal 4, combined block 5, sealing block 6, wherein the lamp base of a fruit 1 is combined in the top of bulb 2, its lower surface is provided with a slot 11, and after the conductor wire 21 of bulb 2 runs through the lamp base of a fruit 1, towards two lateral bucklings upwards; Combined block 5 has a upper flange 51, and its underpart combination has a U type conducting strip 52, and is whole by in the flange 51 embedding slots 11, is combined into one with the lamp base of a fruit 1; Lamp socket 3 inside are provided with two opposed conducting terminals 4, and the electric wire 41 of each conducting terminal 4 then extends downwards, is the connecting line that is connected to the lamp string.

When the lamp base of a fruit 1 plugs together behind lamp socket 3 inside, two conductive filaments 21 of bulb 2 contact with the top of two conducting terminals 4 respectively, the both sides of U type conducting strip 52 are then pressed respectively and are touched in the seat portion of two conducting terminals 4, promptly form conductive communication, make the bulb group compound mode in parallel with being connected to of lamp string, when bulb 2 damaged, the electric current of lamp string still was 52 conductings of U type conducting strip, and can not be affected, and be available for users to find easily the bulb that this damage do not work and change at once.

Shown in accompanying drawing 3 and accompanying drawing 4, be another embodiment of the present utility model, it is the lamp bulb string of a water proofing property, and also be connection in parallel, comprising the lamp base of a fruit 1 is arranged, bulb 2 and lamp socket 3, mainly be that a sealing block 6 is arranged, be provided with arc groove 61 in its both sides, and top is arranged with downward opening U type conducting strip 62, and this sealing block 6 snaps in from the bottom of lamp socket 3, makes U type conducting strip 62 be able to be connected with the conducting terminal 4 of both sides, and but electric wire 41 is lived in the arc groove 61 proper packings of its both sides, obtain the sealing effect of waterproof, this kind manufactures and designs and assembles very simple, waterproof again.
