Description

Technical Field

[0001] The utility model relates to the technical field of light emitting diodes, in particular to an antistatic LED light emitting diode. Background Art

[0002] Light-emitting diodes, referred to as LEDs, are diodes made of compounds of gallium (Ga), arsenic (AS) and phosphorus (P). They can radiate visible light when electrons and holes recombine, so they can be used to make light-emitting diodes, which are used as indicator lights in circuits and instruments, or to form text or digital displays. Commonly used diodes are diodes that emit red, green or yellow light. In order to avoid damage from static electricity, LED light-emitting diodes are coated with antistatic coatings on their surfaces during production to improve the antistatic protection of LED light-emitting diodes. Existing antistatic LED light-emitting diodes need to be recycled after being soldered on circuit boards. When the light-emitting diodes are recycled, the pins soldered to the circuit boards generally need to be cut off before they can be removed, resulting in shorter pins of the recycled diodes, which affects the later use effect.

[0005] (II) Technical solution

[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0007] An antistatic LED light-emitting diode comprises a lampshade, a threaded seat and a light-emitting element. The bottom of the lampshade is fixedly connected to the threaded seat, the light-emitting element is encapsulated inside the lampshade, the bottoms of both sides of the light-emitting element are fixedly connected to contact disks, the threaded seat is threadedly connected to a connecting cover, the connecting cover is connected to a pin, and the pin is arranged to be in contact with the contact disk.

[0008] Furthermore, limiting grooves are symmetrically arranged inside the connection cover.

[0009] Furthermore, a plug-in hole is provided on the connection cover at the position of the limiting groove.

[0010] Furthermore, two pins are provided, and the two pins are respectively divided into a positive pole and a negative pole, and the pins are slidably inserted in the insertion hole.

[0011] Furthermore, a contact spring is fixedly connected to the top of the pin, and the contact spring is adapted to be installed in the limiting groove.

[0012] Furthermore, when the connection cover is screwed on the threaded seat, the two contact springs at the two limiting grooves are respectively connected and abutted against the two contact disks.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides an antistatic LED light emitting diode, which has the following beneficial effects:

[0015] The antistatic LED light emitting diode designed by the utility model can achieve a connection effect by sliding the pin inside the plug-in hole opened and closed on the connecting cover, and cooperating with the adaption connection of the top contact spring of the pin and the limit groove. When the connecting cover is threadedly connected to the threaded seat, the two contact springs can conflict with the two contact disks.

[0027] like Figure 1-8 As shown, an antistatic LED light emitting diode proposed in an embodiment of the utility model, the antistatic LED light emitting diode designed in this scheme, on the basis of the existing light emitting diode coated with an antistatic coating on the surface, optimizes the use effect of the secondary recycling welding of the light emitting diode, improves the convenient recycling of the light emitting diode, comprises a lampshade 1, a threaded seat 2 and a light emitting element 3, the bottom of the lampshade 1 is fixedly connected with the threaded seat 2, the interior of the lampshade 1 is encapsulated with the light emitting element 3, the bottoms of both sides of the light emitting element 3 are fixedly connected with contact disks 4, the threaded seat 2 is threadedly connected with a connecting cover 5, the connecting cover 5 is connected with a pin 10, the pin 10 is arranged to be in contact with the contact disk 4, when the light emitting diode of this scheme is welded and installed, it is welded and used by plugging two pins 10 on the circuit board, and when the light emitting diode needs to be recycled for secondary welding, it can be recycled by cutting the pins 10, when the pins 1 The pin 10 is then pulled out of the socket 7 and the pin 10 is pushed toward one end of the contact spring 11 to remove the cut pin 10. The pin 10 is then replaced with a pin of normal length. The contact spring 11 fixedly connected to the top of the pin 10 will be replaced together when the pin 10 is replaced, so that the pin 10 is plugged into the socket 7. The contact spring 11 is adapted to be installed in the limiting groove 6. The connecting cover 5 is then threadedly connected to the threaded seat 2. When the connecting cover 5 is threadedly tightened on the threaded seat 2, the contact spring 11 will contact the contact disk 4 to achieve the connection effect. The connection can be used for secondary welding at this time. The design of the contact spring 11 can ensure the normal connection between the pin 10 and the contact disk 4 through the rebound resistance force, thereby avoiding the problem of poor connection.

[0028] The utility model designs an antistatic LED light emitting diode. When the light emitting diode is soldered on a circuit board, it is usually necessary to reserve a certain height between the light emitting diode and the circuit board to ensure that there is enough space between the LED light emitting diode and the circuit board. This is mainly to avoid problems such as short circuit or mechanical impact between the LED light emitting diode and the circuit board, and it can also improve the heat dissipation effect of the LED. After the height is reserved between the light emitting diode and the circuit board, it will cause the pin 10 to be easily bent and broken. Therefore, this solution optimizes the design of the above problem. Four folding grooves 8 are provided in a circular array on the back of the connecting cover 5. A rotating hole 9 is provided on the connecting cover 5 at one end of the folding groove 8. The inside of the folding groove 8 is adapted to connect A support leg 12 is connected, one end of the support leg 12 is fixedly connected to a rotating shaft 13, the rotating shaft 13 is rotatably connected in the rotating hole 9, the other end of the support leg 12 is provided with an abutting inclined surface 14, and a notch 15 is provided on the support leg 12 at the same end of the abutting inclined surface 14. By buckling and pulling the notch 15, the support leg 12 is rotated and unfolded through the rotating shaft 13. After the four support legs 12 are rotated and unfolded, the abutting inclined surface 14 is supported on the circuit board, and when a certain height is reserved between the light-emitting diode and the circuit board, the vertical state of the light-emitting diode and the circuit board can be reinforced, and the light-emitting diode will not be skewed to cause the problem of the pin 10 breaking, thereby improving the protection and use of the pin 10. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.

The pin 10 is slidably inserted into the plug hole 7, and a contact spring 11 is fixedly connected to the top of the pin 10. The contact spring 11 is adapted to be installed in the limiting groove 6. The contact spring 11 arranged on the top of the pin 10 can ensure the connection between the pin 10 and the light-emitting element 3. The contact spring 11 can tightly contact the contact disk 4 under the rebound force to avoid the problem of poor contact.
