The specific embodiment
Below by particular specific embodiment explanation embodiments of the present invention, person skilled in the art scholar can understand other advantages of the present invention and effect easily by the disclosed content of this specification.
Notice, the appended graphic structure that illustrates of this specification, ratio, size etc., equal contents in order to cooperate specification to disclose only, understand and reading for person skilled in the art scholar, be not to limit the enforceable qualifications of the present invention, so technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, not affecting under the effect that the present invention can produce and the purpose that can reach, all should still drop on disclosed technology contents and get in the scope that can contain.Simultaneously, quote in this specification as " on ", D score, " left side ", " right side ", " centre " reach the term of " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the present invention, the change of its relativeness or adjustment, under without essence change technology contents, when also being considered as the enforceable category of the present invention.
As shown in Figures 1 to 4, the invention provides a kind of Down lamp of the zhaga of meeting standard and the power supply input structure between the base, comprise base 1 and the cylindrical Down lamp 2 that is connected with described base 1, the excircle of described Down lamp 2 is provided with a connecting circuit board 6 of outwards giving prominence to, described connecting circuit board 6 is provided with power supply input pad 61, be provided with the tank 11 that matches with described connecting circuit board 6 in the described base 1, be fixed with Wiring port 3 on the described base 1, also be fixed with an electroconductive elastic sheet 5 on the described base 1, described electroconductive elastic sheet 5 one ends place in the described Wiring port 3, the other end is provided with the contact 51 of giving prominence to described tank 11, when described connecting circuit board 6 is positioned at tank 11, described contact 51 and described power supply input pad 61 Elastic Contact.
In the power supply input structure between this Down lamp 2 and the base 1, external power source is connected with connecting circuit board 6 on the Down lamp 2 by the electroconductive elastic sheet 5 that is fixed on the base 1, and then realization is to the power supply of Down lamp 2, its overall structure is simple, compact, and contact 51 effectively guarantees fully to contact between the two with the Elastic Contact of power supply input pad 61 during energising, prevents the phenomenons such as outage, loose contact.In the present embodiment, external power source is connected with electroconductive elastic sheet 5 by a wire 4, wire 4 be inserted in the described Wiring port 3 and with the end Elastic Contact of electroconductive elastic sheet 5, simultaneously, contact 51 on the electroconductive elastic sheet 5 is connected with power supply input pad 61 on the connecting circuit board 6 again, and then realizes being connected of external power source and Down lamp 2.
Further, see Fig. 4 and Fig. 6, described electroconductive elastic sheet 5 comprises the body 52 that places base 1 periphery, described body 52 upper ends are extended with flat part 53, the lower end is extended with bending part 54, described flat part 53 is positioned on the upper surface of base 1, and described contact 51 is given prominence to downwards and entered the described tank 11 from the bottom surface of flat part 53; The end of described bending part 54 places in the described Wiring port 3, and described bending part 54 tilts to the direction near Down lamp 2, be that the direction that bending part 54 guiding lines 4 insert tilts, and the length H of bending part 54 greater than body 52 bottoms to the distance B between Wiring port 3 inner surfaces.Like this, toward Wiring port 3 interpolation wire 4 time, strain occurs in electroconductive elastic sheet 5, and the end of bending part 54 can be under the effect of wire 4, and the direction of inserting along wire 4 moves; After wire 4 inserted fully, elastic recoil can occur in the end of bending part 54, and movement by a small margin occurs the direction of namely inserting against wire 4.Since the length H of bending part 54 greater than body 52 bottoms to the distance B between Wiring port 3 inner surfaces, so bending part 54 after resilience, its end can tightly prop up wire 4, and then wire 4 is fixed in the Wiring port 3, prevents that effectively wire 4 from becoming flexible, coming off.
When being installed in Down lamp 2 on the base 1, rotate first Down lamp 2, the projection on Down lamp 2 outer circumference surfaces is stuck in the draw-in groove of base 1, realize fixing; Simultaneously, connecting circuit board 6 also snaps in the tank 11 of base 1, make contact 51 Elastic Contact on power supply input pad 61 and the electroconductive elastic sheet 5 on the connecting circuit board 6, in this process, flat part 53 imposes at connecting circuit board 6 under the active force of contact 51 and may misplace.For guaranteeing that flat part 53 only at Down lamp 2 play occurs axially, so also be provided with spacing hole 531 on the described flat part 53, the upper surface of described base 1 is provided with limited post 12, described limited post 12 places in the described spacing hole 531, see Fig. 4 and Fig. 5, prevent that effectively flat part 53 from play occuring in the other direction.
Further, as shown in Figure 4 and Figure 5, described base 1 is provided with through hole 13, and described through hole 13 is positioned at the top of described tank 11 and is connected with tank 11, and described contact 51 is passed described through hole 13 and entered in the tank 11.
Preferably, see Fig. 1 and Fig. 6, described electroconductive elastic sheet 5 both sides are equipped with outwards outstanding connecting portion 55, and described connecting portion 55 and base 1 are fixedly connected with by securing member.Described electroconductive elastic sheet 5 preferably adopts copper splinter, and described base 1 preferably adopts plastic feet 1, is convenient to batch production and makes, and effectively reduces Down lamp 2 costs.
During assembling, first electroconductive elastic sheet 5 is placed and is fixed on the base 1, again Wiring port 3 is fixed on the base 1, namely finish the assembling of base 1.During installation, base 1 is fixing, and with in the wire 4 insertion Wiring ports 3, and in the end of bending part 54 Elastic Contact, form conducting; Down lamp 2 is installed, and rotation Down lamp 2 makes contact 51 Elastic Contact on power supply input pad 61 and the electroconductive elastic sheet 5 on the connecting circuit board 6; Energising, Down lamp 2 just can work.
In sum, the present invention has effectively overcome various shortcoming of the prior art and the tool high industrial utilization.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not is used for restriction the present invention.Any person skilled in the art scholar all can be under spirit of the present invention and category, and above-described embodiment is modified or changed.Therefore, have in the technical field under such as and know that usually the knowledgeable modifies or changes not breaking away from all equivalences of finishing under disclosed spirit and the technological thought, must be contained by claim of the present invention.
