Description

Lamp base of a fruit waterproof safety structure

The utility model relates to the lighting class, particularly a kind of lamp base of a fruit waterproof safety structure.

Because it is outdoor that the combination of the bulb of lamp string often is used in, so water-proof function is one of necessary consideration project when becoming the design of lamp string, and most of existing structure mainly is to utilize urgent mode, lamp socket, the lamp base of a fruit and bulb is fitted tightly, to reach the effect that prevents infiltration; Then, because of the bottom surface of lamp socket must be provided with perforate, run through and finish and conduct with supply lines, the electric wire preformed hole causes infiltration easily, and destroys the normal function of bulb group.

The purpose of this utility model provides a kind of lamp base of a fruit waterproof safety structure, can overcome the shortcoming of prior art.

The technical solution of the utility model is such: it includes the lamp base of a fruit, lamp socket, a bulb and a belled body, wherein belled body is arranged between the lamp base of a fruit and the lamp socket, hold under the fit lamp base of a fruit on this belled body, then wear under the belled body and close in lamp socket, under belled body, be provided with emptying aperture in addition, respectively establish arc groove in both sides, engage for electric wire, and make wire terminal stretch into belled body inside, contact with the conductive filament that is positioned at both sides, lamp base of a fruit lower end, the lower edge in belled body is provided with protruding lip again, makes the lamp base of a fruit, the mutually tight fit of lamp socket and belled body, and closely compel to close wherein electric wire between belled body and lamp socket, and reach complete waterproof infiltration.

Edge is provided with inside clamping edge within perforate on the lamp base of a fruit in addition, with edge outside the packing applying bulb; Respectively establish in the first half both sides of belled body again, and respectively establish with arc groove the Lower Half both sides of belled body with slot, the supply lines engaging, and terminal is to be fastened in the slot; Lamp base of a fruit lower end is provided with two flats again, supplies the conductive filament bending of bulb to attach, and contacts with wire terminal.

Below in conjunction with accompanying drawing and embodiment the utility model is made a detailed description.

Consult shown in Fig. 1,2, include the lamp base of a fruit (2), lamp socket (3), bulb (4), and the belled body of feature (1), the first half of belled body (1) is a round, for the tight fit lamp base of a fruit (2), the lamp base of a fruit (2) is worn and is closed for bulb (4), and after two conductive filaments (41) of bulb (4) passed downwards, bending fitted in the lamp base of a fruit (2) both sides, lower end.The Lower Half of belled body (1) is a flat, just can wear and be combined within the lamp socket (3) sky and ask, and for closely cooperating, belled body (1) lower end plat part is provided with emptying aperture (11), and respectively establish with arc groove (12) in both sides, provide electric wire (5) to snap in it, and the terminal (51) of electric wire (5) stretches within the belled body (1), and contact with two conductive filaments (41) of bulb (4).Then establish with protruding lip (13) the lower edge both sides of belled body (1), behind the mutual fit of each member, all obtain absolute urgent effect, particularly electric wire (5) be subjected to lamp socket (3) inner edge and belled body (1) compel close, can prevent the infiltration at this position, overcome existing shortcoming.

Shown in Fig. 3,4, (3 a) structures, and that the bottom of belled body (1a) also is made as is cylindric are to reach packing combination mutually for the utility model is applied in cylindrical lamp socket.Another feature of the utility model is the design of the lamp base of a fruit (2), and shown in Fig. 5,6, the inner edge that the lamp base of a fruit (2) is gone up perforate is provided with an inside clamping edge (21), bulb (4) is inserted in after, can effectively fit, prevent the infiltration of moisture content.

Figure 7 shows that the change application example of the utility model, wherein form two slots (1b1) on the belled body (1b), and Lower Half is cylindric, and be provided with arc groove (1b2), lower edge also has protruding lip (1b3), electric wire (5) is fastened in the arc groove (1b2), terminal (51) is contained in the slot (1b1), integral body is to be combined in the lamp socket (3b), end is made as two flats (2b1) under the lamp base of a fruit (2b), attach bending for the conductive filament (41) of bulb (4), and when the lamp base of a fruit (2b) be placed in hold on the lamp socket (3b) after, two conductive filaments (41) conducting that contacts with two-terminal (51) respectively.This belled body that changes moulding designs, and the water-proof function of equivalence also can be arranged.Figure 8 shows that to change belled body (1c) external form that to cooperate the moulding of circular lamp receptacle (3c) fully, Fig. 9 then is the symmetry change design of flat.Figure 10 is the assembled sectional view of last embodiment, and wherein conductive filament (41) is the form of ecto-entad bending, and this state also can be changed to outwards bending structure as shown in figure 11, is the design of the modification transformation of the utility model.

In sum, reasonable in design of the present utility model can make the lamp base of a fruit (2), lamp socket (3) and belled body (1) packing fit mutually, forms the structure of complete packing, reaches the function of safe waterproof infiltration effectively.
