Abstract
The utility model discloses a light-emitting diode easy to identify positive and negative polar pins. Any one angle or one side of an encapsulating part 13 is provided with an unfilled angle 14 or corresponding marks to differentiate the positive and the negative polar pins 11, 12; simultaneously, the positive and the negative polar pins 11, 12 are designed with equal length. The structure facilitates users to differentiate the positive and the negative polar pins 11, 12 of the light-emitting diode 1, and is time-saving and convenient.
Description
The utility model relates to electronic devices and components, particularly a kind of light-emitting diode that is easy to identification positive and negative electrode pin.
In the current growing epoch of science and technology, electronic product almost becomes the indispensable articles for use in every household, such as: calculator, computer, TV etc., and light-emitting diode is one of the most frequently used electronic component of assembling electronic product, but common light-emitting diode just, the negative pole pin is differentiated and how to be distinguished with the length of utmost point pin, as Fig. 1, shown in Figure 2, utmost point pin is anodal than the elder, the shorter one is a negative pole, when utmost point pin wrecks when being isometric relatively or being opposite length, cause the user just being difficult for distinguishing easily, the negative pole pin, and need to measure resolution by instrument, cause and use inconvenience, in addition, the anodal pin of light-emitting diode is longer, in the time will being welded in light-emitting diode on the circuit board, must cut off the unnecessary length of anodal pin earlier could weld, and loses time.
The purpose of this utility model provides and a kind ofly is easy to differentiate the positive and negative electrode pin and conveniently is welded in light-emitting diode on the circuit board.
For reaching above-mentioned purpose, the utility model by the following technical solutions:
The utility model is to be provided with unfilled corner or respective markers in the encapsulation of light-emitting diode any one jiao or a side, and in order to distinguish the positive and negative electrode pin, the positive and negative electrode pin is isometric simultaneously, conveniently to be welded on the circuit board.
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is the three-dimensional appearance schematic diagram of common light-emitting diode.
Fig. 2 is the floor map of common light-emitting diode.
Fig. 3 is a three-dimensional appearance schematic diagram of the present utility model.
Fig. 4 is a floor map of the present utility model.
Fig. 5 is another embodiment three-dimensional appearance schematic diagram of the present utility model.
Fig. 6 is another embodiment floor map of the present utility model.
1, be that light-emitting diode, 11 is that anodal pin, 12 is that negative pole pin, 13 is that encapsulation, 14 is that unfilled corner, 15 is aperture.
As shown in Figure 3, Figure 4, the utility model mainly is that the positive and negative electrode pin 11,12 with light-emitting diode 1 is made as isometric, and the encapsulation 13 of light-emitting diode 1 any one jiao or a side are provided with unfilled corner 14 or corresponding mark, in order to distinguish positive and negative electrode pin 11,12, this unfilled corner 14 can be anodal mark or negative pole mark; When the user will weld light-emitting diode 1 on circuit board the time, only need according to unfilled corner 14 on the encapsulation 13 of its light-emitting diode 1 fixed utmost point footnote note, the positive and negative electrode pin 11,12 that can correctly weld light-emitting diode 1 is on circuit board; In addition, the utility model positive and negative electrode pin 11,12 is made as isometric, is welded in time on the circuit board to save light-emitting diode 1, and saves Material Cost, makes the utility model tool economic benefit.
As Fig. 5, shown in Figure 6, the utility model can be established an aperture 15 at the moderate place in encapsulation 13 right sides or left side of light-emitting diode 1 and serve as a mark, in order to distinguish the positive and negative electrode pin 11,12 of light-emitting diode 1.
Claims (3)
1, a kind of light-emitting diode, it includes encapsulation and positive and negative electrode pin, it is characterized in that, and the positive and negative electrode pin is isometric, and encapsulation any one jiao or a side are provided with the mark of unfilled corner, in order to distinguish the positive and negative electrode pin.
2,, it is characterized in that the unfilled corner of said encapsulation can be made as aperture or corresponding mark according to the described a kind of light-emitting diode of claim 1.
3, according to the described a kind of light-emitting diode of claim 1, it is characterized in that the unfilled corner on the said encapsulation, can be anodal mark or negative pole mark.
