The utility model discloses a kind of LED display light-emitting diode, comprise anode rod, cathode rod, chip and circular colloid, described anode rod and cathode rod bottom are all provided with terminal pin, described terminal pin is also provided with a fusoid thread casing, this thread casing coupling is inserted in the plug wire hole of display screen mounting panel, and the host cavity that the inside of this thread casing penetrates for convenience of terminal pin, the sidewall of described thread casing has at least one and facilitate sealing fluid to flow into open slot in plug wire hole.The utility model mounting structure is firmly stable, alleviates the overall weight of LED display, and practical, is worthy to be popularized.
Description
Technical field
The utility model relates to a kind of LED display light-emitting diode.
Background technology
At present, LED it directly electricity can be converted into light.The heart of LED is the wafer of a semiconductor, and one end of wafer is attached on a support, and one end is negative pole, and the other end connects the positive pole of power supply, and whole wafer is got up by epoxy encapsulation.Semiconductor wafer is made up of two parts, and a part is P type semiconductor, and inside it, occupy an leading position in hole, and the other end is N type semiconductor, at this side mainly electronics.But time these two kinds of semiconductors couple together, between them, just form one " P-N junction ".When electric current acts on this wafer by wire time, electronics will be pushed to P district, and in P district, electronics is with hole-recombination, then will send energy with the form of photon.
LED display (LEDdisplay, LED Screen): be again electronic display or the word screen that wafts.Be widely used in shops's shop front, transport information report, large-scale outdoor advertising medium etc.Be made up of light-emitting diode and led pc panel, by redness, blue, white, the light on and off of green LED lamp show word, picture, animation, video, content, can according to different occasion need make different adjustments.
The light-emitting diode that LED display uses when mounted, encapsulate after pin directly being inserted the plug wire hole of display screen mounting panel, and in order to ensure the firmly stable of encapsulating structure, not only in plug wire hole, inject a large amount of packing colloids, and a large amount of packing colloid that also bonds outside hole, the required packaging plastic scale of construction is very large, but the effect of reality is not very remarkable, or thus not firmly problem installed by diode, the packaging plastic scale of construction greatly also adds the weight of whole LED display, and but existing LED display generally all adopts wall hanging or steelframe to support installation, there is LED display deadweight overweight, produce and unsteady hidden danger is installed, in addition when light-emitting diode inserts the plug wire hole of display screen mounting panel, because light-emitting diode positive and negative does not identify, cause that the two poles of the earth of light-emitting diode are bad to be determined, anti-inserted the moon is there will be toward contact, the problem of anode.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, proposes a kind of LED display light-emitting diode.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of LED display light-emitting diode, comprise anode rod, cathode rod, be arranged on the chip of cathode rod head, and encapsulate described anode rod, the circular colloid of cathode rod and chip, described anode rod and cathode rod bottom are all provided with terminal pin, it is characterized in that: described terminal pin is also provided with a fusoid thread casing, this thread casing coupling is inserted in the plug wire hole of display screen mounting panel, and the host cavity that the inside of this thread casing penetrates for convenience of terminal pin, the sidewall of described thread casing having at least one facilitates sealing fluid to flow into open slot in plug wire hole, the front end of described circular colloid is provided with a blindmate discrimination points.
Preferably, described blindmate discrimination points is band the colorful one resin mass.
Preferably, described open slot is the axis setting that square groove is parallel to thread casing, and the quantity of open slot is two.
Compared with prior art, the utility model have employed novel structural design, terminal pin is set up a thread casing, thread casing can not only play the effect adding strong stability when terminal pin is installed, and the open slot arranged when can facilitate sealing sealing fluid permeability flow in thread casing and the direct gap of plug wire hole strengthen firm, and decrease the consumption of packing colloid, alleviate the weight of whole LED display, convenient installation, the positive and negative of the blindmate discrimination points arranged convenient identification light-emitting diode, facilitate the installation of light-emitting diode, total is simple, practical, be worthy to be popularized.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is scheme of installation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, utility model is described in detail.
As Fig. 1, shown in 2, a kind of LED display light-emitting diode that the utility model proposes, comprise anode rod 1, cathode rod 2, be arranged on the chip 3 of cathode rod head, and encapsulate described anode rod, the circular colloid 4 of cathode rod and chip, anode rod and cathode rod bottom are all provided with terminal pin 5, terminal pin 5 is also provided with a fusoid thread casing 6, this thread casing 6 coupling is inserted in the plug wire hole 7 of display screen mounting panel, and the host cavity 61 that the inside of this thread casing 6 penetrates for convenience of terminal pin, the sidewall of thread casing having at least one facilitates sealing fluid to flow into open slot 62 in plug wire hole 7, the front end of circular colloid 4 is provided with a blindmate discrimination points 8.Blindmate discrimination points is band the colorful one resin mass.The axis that open slot 62 is parallel to thread casing for square groove is arranged, and the quantity of open slot is two.
See Fig. 2, the direction of arrow in figure is the flow direction of sealing fluid, in the utility model, cave in the diameter at place at the middle part that the diameter of terminal pin 5 is less than thread casing 6, and terminal pin 5 welds at the place of caving in of thread casing 6, make structure more stable, the sealing fluid after welding during encapsulation can penetrate in plug wire hole 7 smoothly.
Above-described embodiment only have expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the utility model patent and protection range should be as the criterion with appended claims.
