Description

A kind of improved LED encapsulating shells of structure

Technical field

The utility model is related to the part that LED is assembled, and refers in particular to a kind of improved LED encapsulating shells of structure.

Background technology

LED wafer is the main raw material(s) of LED, and LED relies primarily on the chip to light.Enable the LED wafer It is enough luminous, then need to set the encapsulating shell used cooperatively with the LED wafer.

Existing encapsulating shell generally comprises a main casing and the positive and negative electrode on the upside of the main casing, LED wafer It is encapsulated on the main casing and is connected with positive and negative electrode, then is electrically connected with city by the electric conductor on the downside of main casing.But it is existing There are the following problems for encapsulating shell in having technology：1st, easily with electric conductor there is relative displacement in main casing, so that the luminous effects of LED It is really unstable；2nd, because electric conductor is in order to keep it to radiate and conductive effect, often exposed setting, this causes encapsulating shell in fortune In defeated, installation process, electric conductor is easily damaged due to being collided and then influences using effect.

Utility model content

The utility model provides a kind of improved LED encapsulating shells of structure, and its main purpose is in overcoming existing encapsulating shell Main casing easily there is relative displacement and electric conductor with electric conductor and easily occur the defect of bending due to being collided.

In order to solve the above technical problems, the utility model is adopted the following technical scheme that：

A kind of improved LED encapsulating shells of structure, including a main casing, the main casing is provided with electrode layer, also including one The convex electric conductor electrically connected with the electrode layer and the filling block being installed on the inside of the convex electric conductor, the convex are conductive The upper end of body is that each side there is one group of elasticity for bending inwards to bind foot for a convex portion, lower end, and two groups of elasticity is bound foot symmetrical And between there is an opening, the main casing is connected by being opened in the lower concave part on the downside of it with the convex portion, the filling The bottom of block is extended in the opening, and the horizontal line where lowermost end of being bound foot no more than the elasticity.

Further, the elasticity to be bound foot also be folded upward to its end and abutted with the filling block.

Further, one is offered on the upside of the main casing is used to house the article putting groove of LED wafer, and the electrode layer sets In the glove trench bottom.

Further, the electrode layer includes three positive electrodes and a negative electrode.

Further, the number bound foot of elasticity is two described in two groups, wherein three elasticity bind foot for respectively with three The positive electrode pin that the positive electrode is connected one by one, another elasticity negative electrode for being to be connected with the negative electrode of binding foot draws Pin.

Compared to the prior art, the beneficial effect of the utility model generation is:

The utility model simple structure, practical, the elasticity bent inwards by setting is bound foot, it is possible to prevente effectively from bullet The end that property is bound foot is collided and damages；By set extend to two groups of elasticity bind foot between opening in filling block, can To play a part of the strong point, it is to avoid elasticity stress of binding foot is excessive and reduce service life；The convex being connected by setting is led Electric body convex portion and main casing lower concave part, can greatly improve the tight ness rating between main casing and convex electric conductor, it is to avoid Liang Zhefa , there is relative displacement in raw relative displacement, greatly improve between the two so as to avoid convex electric conductor with the electrode layer on main casing LED luminous stability.

Specific embodiment

Specific embodiment of the present utility model is illustrated with reference to the accompanying drawings.

Reference picture 1, Fig. 2 and Fig. 3.A kind of improved LED encapsulating shells of structure, including a main casing 1, on the main casing 1 Electrode layer 2 is provided with, also including a convex electric conductor 3 electrically connected with the electrode layer 2 and is installed in the convex electric conductor 3 The filling block 4 of side.The upper end of the convex electric conductor 3 is that a convex portion 31, lower end each side bends inwards with one group Elasticity binds foot 32, two groups of elasticity bind foot 32 it is symmetrical and between there is an opening 33, the main casing 1 is by being opened under it The lower concave part 11 of side is connected with the convex portion 31, and the bottom of the filling block 4 is extended in the opening 33, and no more than institute Horizontal line where stating elastic 32 lowermost ends of binding foot.Elasticity is bound foot and 32 can also be folded upward to its end being supported with the filling block 4 Connect.32 are bound foot by the elasticity that bends inwards of setting, it is possible to prevente effectively from elasticity is bound foot, 32 end is collided and damages；It is logical Cross set extend to two groups of elasticity bind foot between opening in filling block, the strong point can be played a part of, it is to avoid elasticity bag The stress of pin 32 is excessive and reduces service life；The convex electric conductor convex portion 31 being connected by setting and main casing lower concave part 11, The tight ness rating between main casing 1 and convex electric conductor 3 can be greatly improved, it is to avoid both occur relative displacement, it is convex so as to avoid There is relative displacement in shape electric conductor 3, substantially increase the luminous stability of LED between the two with the electrode layer 2 on main casing 1.

Reference picture 1, Fig. 2 and Fig. 3.The upside of the main casing 1 offers one is used to house the article putting groove 12 of LED wafer, The electrode layer 2 is located at the bottom of the article putting groove 12.The bottom opening 121 of the article putting groove is substantially into square, and its side A length of 1.50mm.The open top 122 of the article putting groove is also substantially into square, and its length of side is 2.20mm.By setting The length of side of 12 open top of article putting groove 122 is more than the length of side of bottom opening 121, can effectively strengthen radiating when the utility model is used Effect.

Reference picture 1, Fig. 2 and Fig. 3.The electrode layer 2 includes three positive electrodes 21 and a negative electrode 22, adjacent two Electrode is separated by insulating tape 23.Bind foot 32 number of elasticity described in two groups is two, wherein three elasticity bind foot for point The positive electrode pin 321 not being connected one by one with three positive electrodes 21, another elasticity is bound foot and is and the negative electrode 22 The negative electrode pin 322 of connection.Bind foot 32 size of each elasticity is in the present embodiment：Length on left and right directions Length 0.70mm on 0.75mm, fore-and-aft direction, this numerical value can reach optimal conductive effect.

Specific embodiment of the present utility model is above are only, but design concept of the present utility model is not limited thereto, All changes for carrying out unsubstantiality to the utility model using this design, all should belong to the row for invading the utility model protection domain For.
