Abstract

The utility model discloses a lamp bulb and lamp socket structure for decorative lamps, particularly a lamp bulb and a lamp socket structure specially used for decorative lamps without a fixing sleeve. The utility model makes a water retaining convex block of a lamp bulb, the water retaining concave part of an end and a lamp base and a wedge-shaped insertion groove mutually inserted and fixed to make a coincident mask change in the vertical and horizontal direction. Thus the utility model can prevent water directly entering the lamp base for accumulation. In addition, the utility model utilizes the holding part of an electricity conduction sheet to hold the end of the lamp bulb to make a conduction wire on the end of the lamp bulb and the holding part of the electricity conduction sheet steadily keep contact.

Description

A kind of decorative lamp bulb and holder structure

The utility model relates to a kind of bulb and holder structure of decorative lamp, refers to a kind of bulb and holder structure that is exclusively used in no fixed cover decorative lamp especially.

Known decorative lamp is mostly adopted Christmas bulb and lamp socket combines (as Fig. 6), wherein Christmas bulb 51 bottoms all cover a fixed cover 52, the lead 53 at Christmas bulb 51 the two poles of the earth passes reflexed by fixed cover 52 bottoms, again fixed cover 52 is embedded in the standby lamp socket 54 together with bulb 51, make fixed cover 52 and lamp socket 54 closely chimeric, this moment, lead 53 and the lamp socket 54 built-in conducting strips (not marking) at bulb 51 the two poles of the earth were electrically connected.In known structure, the function of fixed cover 52 mainly is to provide structural reinforcement to strip Christmas bulb 51, guarantees that lead 53 contacts with the stable of conducting strip in the lamp socket 54; Be that on the other hand mat fixed cover 52 increases the dash function of 54 of bulbs 51 and lamp sockets, avoid water directly to enter lamp socket 54 in a large number and in accumulating in, two poles is short-circuited.

If bulb and lamp socket can provide dash and fixed function than driving fit from body structure, and conducting strip also can provide more firm conduction contact to the lead of light bulb base, and then fixed cover can be removed, to save the cost of element and assembling.

Main purpose of the present utility model is to provide a kind of need not be provided with fixed cover, and the decorative lamp bulb and the holder structure of good dash, fixed function and conduction contact can be provided again.

For achieving the above object, solution of the present utility model is: a kind of decorative lamp bulb and holder structure, mainly form by bulb, lamp socket, conducting strip, power line and connecting support, wherein the bulb bottom has a horizontal edge, middle body extends to form a dash projection downwards, this dash projection below is extended an end downwards, and this end peripheral hardware connects the lead at bulb the two poles of the earth; The lamp socket neck forms a diameter less than bulb bottom horizontal edge, and shape and space and the corresponding dash depressed part of bulb bottom dash projection, this dash depressed part digs downwards again establishes formation one and the corresponding wedge shape caulking groove of bulb end shape and space, and the bottom of this wedge shape caulking groove is provided with for two conducting strips and wears the fixed stop hole of build-in; The conducting strip bottom has sharp-pointed portion, the upper end has resilient clamp portion, and this conducting strip is worn the stop hole of build-in due to the wedge shape caulking groove in advance, and makes resilient clamp portion be revealed in wedge shape caulking groove inside, sharp-pointed portion then is revealed in the lamp socket below, can lunge the position of power line when being positioned at combination; Bulb is by dash depressed part, the mutual build-in of wedge shape caulking groove of dash projection, end and lamp socket, and the lamp socket bottom combines with connecting support and power line is held wherein, this moment, bulb end system inserted in the resilient clamp portion of conducting strip, and the resilient clamp portion of the lead of bulb end and conducting strip keeps in touch, and the sharp-pointed portion of conducting strip lunges power line makes electrical communication.

Above-mentioned a kind of decorative lamp bulb and holder structure, wherein the lamp socket bottom is provided with card article, and the connecting support relevant position is provided with draw-in groove; The bulb edge has the annular recess that holds the lamp socket neck to top formation one.

After adopting such scheme, the dash depressed part of dash projection, end and the lamp socket of mat bulb bottom, the mutual build-in of wedge shape caulking groove make both overlap the variation that mask has vertical and horizontal.If the water desire is infiltrated interior stopping by bulb bottom horizontal edge and lamp socket neck intersection earlier of lamp socket, change direct of travel again and then stop that by dash projection and dash depressed part intersection bulb like this and lamp socket manifest the dash function from the change of body structure more; When bulb and lamp socket build-in, bulb end system closely is fixed in the wedge shape caulking groove on the other hand, and the clamping part of the lead of bulb end and conducting strip is stable at this moment keeps in touch.

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

Fig. 6 is known Christmas bulb and lamp socket combination schematic diagram.

See also shown in Fig. 1,2, the utility model mainly is to be made up of bulb 1, lamp socket 2, conducting strip 3, power line 6 and connecting support 4, wherein:

Bulb 1 bottom has a horizontal edge 11 that contracts and form in the center of circle, middle body extend to form downwards one with the corresponding dash projection 12 of lamp socket dash depressed part 21 shapes, these dash projection 12 belows, extend downwards again one with lamp socket 2 wedge shape caulking grooves 22 shape respective end portions 13, this end 13 peripheral hardwares connect the lead 14 at bulb the two poles of the earth.

Lamp socket 2 necks 25 form a diameter less than bulb bottom edge 11, and shape and space and bulb bottom dash projection 12 corresponding dash depressed parts 21, this dash depressed part 21 digs downwards again establishes formation one and the corresponding wedge shape caulking groove 22 of bulb end 13 shapes and space, the bottom of this wedge shape caulking groove 22 is provided with for two conducting strips 3 and wears the fixed saturating empty stop hole 26 (ginseng Fig. 3) of build-in, and lamp socket 2 two bottom sides have the card article 23 that fixes with connecting support 4.

Shown in Fig. 3,4, conducting strip 3 bottoms have the sharp-pointed portion 32 that can puncture power line 6, but the upper end has the resilient clamp portion 31 of clamping bulb end 13, and this conducting strip 3 is worn the saturating empty stop hole 26 of build-in due to wedge shape caulking groove 22 in advance, and make resilient clamp portion 31 be revealed in wedge shape caulking groove 22 inside, sharp-pointed portion 32 then is revealed in lamp socket 2 belows, can lunge the position of power line 6 when being positioned at connecting support 4 combinations.

Aforementioned bulb 1 is by dash depressed part 21, the wedge shape caulking groove 22 mutual build-ins of dash projection 12, end 13 and lamp socket 2, earlier power line 6 is placed 4 of lamp socket 2 and connecting supports again, the card article 23 that utilizes lamp socket 2 and the draw-in groove of connecting support 4 43 are combined the three, this moment, bulb 1 end 13 was to insert in the resilient clamp portion 31 of conducting strip 3, and the lead 14 of bulb 1 end 13 and the resilient clamp portion 31 of conducting strip 3 keep in touch, and the sharp-pointed portion 32 of conducting strip 3 lunges power line 6 and makes electrical communication.

Fig. 5 is another embodiment of the present utility model, itself and the last embodiment main distinction are: bulb 1 horizontal edge 11 is recessed to form an annular recess 15 that can hold lamp socket 2 necks 25 to the top, when bulb 1 and lamp socket 2 build-ins, lamp socket 2 necks 25 are just in time covered by the annular recess 15 of bulb 1 bottom.Increase the tortuosity that water enters lamp socket 2 paths thus, improve the dash function of bulb 1 and lamp socket 2 intersection more.
