See also shown in Fig. 1-8, the present invention's " transformation plug waterproof construction of band female plug seat " covers 50 by a shell 10, two power supply guide cards 20, a voltage transformation unit 30, a bonnet 40, a back of the body, and a watertight composition 60 members such as grade are formed, wherein:
This shell 10 is the inner edge hollow housing, and appropriate location has been horizontally set with one first dividing plate 11 between front end two side inner walls, its inner rim is separated into the preceding holding part 12 and the back holding part 13 of two separate space.Should be provided with for this this two power supply guide cards 20 by preceding holding part 12, and between this two power supplys guide card 20, establish a second partition 14 that vertically is linked between this first dividing plate 11 and shell 10 front end walls, holding part 12 is divided into the space of two sealings before further will being somebody's turn to do.Secondly should be provided with for this voltage transformation unit 30 by back holding part 13, and offer a draw-in groove 15 that is communicated with this back holding part 13 in these shell 10 rear ends, use for this bonnet 40 to be provided with, and utilize to carry on the back and cover 50 and covered sealing.The ora terminalis of this first dividing plate 11 and second partition 14 upper ends has respectively protruded out a flange 16 again, can be positioned this shell 10 outer rims for these bonnet 40 embedding groups.
This two power supplys guide card 20 generally is the metal sheet of foretelling font, before these shell 10 ejection formations, this two power supplys guide card 20 placed in the mould and to should before the position of holding part 12, and after these shell 10 ejection formations finish, even these two power conductors, 20 one are fixedly arranged on this shell 10 1 ends.Respectively this power supply guide card 20 is positioned at an end of this shell 10 again, elongation moulding one back of the body is inserted linkage section 21 and transformation linkage section 22, the slotting linkage section 21 of this two back of the body lays respectively in two lateral margins of these preceding holding part 12 separations, and form with 14 collocation of this second partition can be for female socket aperture 23 of another attaching plug insert group, utilize the formation of this second partition 14, when rainwater infiltrates, can make electric current can not produce short circuit phenomenon by this two power supplys guide card 20.Secondly this two transformations linkage section 22 penetrates this first dividing plate 12, makes that its ora terminalis is protruding to be exposed in this back holding part 13, in order to this voltage transformation unit 30 of electrically connect.
In addition, as shown in Figure 6, this second partition 14 can increase thickness of slab, and in centre position formation hollow bulb 141, in order to the waterproof isolation effect between holding part 12 2 side inside before increasing, and the size positions of stablizing female socket aperture 23 its cavernous structures, promote the steadiness of the power supply guide card insert group combination of another plug.
This voltage transformation unit 30 is mounted on this back holding part 13 places, by junctions 33 and two back junctions 34 before the circuit board 31, some electronic components 32, two, and member composition such as a photo resistance 35.This circuit board 31 is cross-placed on the edge that this shell 10 is positioned at back holding part 13; These electronic components 32 are located on the plate face of electroplax plate 31, in order to alternating current is converted to direct current, and this before two junction 33 be located at the front end that 31 pairs of circuit boards should two power supply guide cards 20, in order to an end of this transformation linkage section 22 of electrically connect.Secondly this two backs junction 34 is located at circuit board 31 rear ends, and the place, outer end is provided with the Access Division 341 of groove shape, and in order to the end that these bonnet 40 1 ends of electrically connect protrude, this photo resistance 35 then is located at 31 pairs of this circuit boards and should be carried on the back on 50 the curtain plate face of covering.
This bonnet 40 is mounted on draw-in groove 15 places of this shell 10, and it convexes with two to medial extremity that should voltage transformation unit 30 and electrically meets portion 41, with these two backs junction 34 electrically connects.Hold inner edge two electric wires that then stretch out to meet portion 42 in addition, use electric wire 71 electrically connects for lamp string 70.
This back of the body cover 50 pairs should shell 10 outer rims tabular lid, cover on the preceding holding part 12 of this shell 10 and back holding part 13 outer rims.Its to should two the end that is provided with of power supply guide cards 20 be formed with two socket apertures that run through 51, and in to should first dividing plate 11 and the inner platform face place of second partition 14 form groove 52, utilize the flange 16 of this first dividing plate 11 and second partition 12 outer ends to be sticked in corresponding groove 52 places, and reach this preceding holding part 12 2 side interior waterproofs design.Should cover the gummed portion 53 that 50 curtain plate faces form depression by the back of the body again, and use for watertight composition 60 and form the usefulness of adhering to.In addition, the appropriate location that 50 pairs on this back of the body lid should photo resistance 35 forms an open-work 54, and establishes a gag 55 with hyalomere 551 in these open-work 54 places.Can utilize the bright and dark light of this photo resistance 35 from this hyalomere 551 inductions space environment of living in, as plug with the controlling mechanism of the automatic conducting of power supply to lamp string 70.
In addition as shown in Figure 2, the present invention also can not must be provided with members such as photo resistance 35 and gag 55 on structure Design, and the circuit formula of control lamp string 70 flickers can be set on the circuit board 31 of voltage transformation unit 30.The electric wire of this bonnet 40 meets portion 42 in addition, also can be designed to the structure of single hole, to cooperate corresponding terminal plug (not shown) plant combination.
This watertight composition 60 takes shape in the edge that this back of the body lid 50 and bonnet 40 and these body 10 skins join, in order to seal the slot that these component sets are established.Technical what use, this watertight composition 60 can be polypropylene (PP), polyethylene (PE), polystyrene (PS), Merlon thermoplastic plastic rubbers such as (PC); It perhaps is acrylonitrile-butadiene-styrene copolymer compound (ABS) or the like artificial rubber.The practice of moulding places the plug that assembles in the mould, utilizes and coats injection molding method in the mould, and this watertight composition 60 is taken shape in the outer rim place that this body 10 and the back of the body cover 50, bonnet 40 joins.
Thus, utilize this first dividing plate 11 and second partition 12 with this shell 10 in order to the inner edge space that this two power supplys guide card 20 and voltage transformation unit 30 are set do independent zones every, see through this watertight composition 60 again and be formed at that this body 10 and the back of the body covers 50, the slit of bonnet 40 outer rim windings is located, reach certain waterproof effect.Moreover, utilize the setting of this photo resistance 35, and carry on the back the hyalomere 551 that covers formation on 50, can make plug automatically along with the light and shade of light, the automatic conducting of power supply to lamp string 70 is reached human oriented design more easily, to meet practical demand.
The above description of this invention is illustrative, and nonrestrictive, and those skilled in the art is understood, and can carry out many modifications, variation or equivalence to it within spirit that claim limits and scope, but they will fall within the scope of protection of the present invention all.
