Description

Technical Field

[0001] The present invention relates to a diode fixing structure, and in particular to a light emitting diode fixing structure. Background Art

[0002] In the current manufacturing and processing of circuit boards, light emitting diodes are common semiconductor devices, usually used to be installed on a metal panel to indicate the operating status of a device, such as working, faulty, monitoring and other statuses, directly reflecting the working conditions of the device and the communication between devices. Due to the characteristics of low power consumption, high efficiency, long life, fast response, anti-vibration, anti-interference, etc. of light emitting diodes, they have been widely used in the fields of railways, lighting, communications, automobiles, medical treatment, etc.

[0003] In existing devices, most light emitting diodes use long pins, which form a 90° angle with the front panel of the device, and the pins are used as connecting wires for electrical connection. For example, the light emitting diode mounting device disclosed in Japanese Patent JP58003319Y2 specifically assembles through two discrete components to fix the light emitting diode in a combined form.

[0004] This combined method has the situation of internal sawtooth tripping and loose buckling in actual applications, and it is necessary to fix it with glue. Summary of the Invention

[0005] The purpose of the present invention is to provide a light emitting diode fixing structure. Through the design of two first engaging pieces and two second engaging pieces, on the one hand, the light emitting diode can be fixed, and on the other hand, it can be reversely fixed on the device panel by relying on the outward supporting force provided by the light emitting diode to form a firm support, and it is also convenient to disassemble by relying on the longer second engaging piece, so as to reduce the maintenance cost and improve the fixing effect while saving materials.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A light emitting diode fixing structure includes:

One end of the first arc-shaped piece is fixed on the annular base, and the other end is connected to one end of the second arc-shaped piece. The outer diameter of the second arc-shaped piece is larger than that of the first arc-shaped piece, and a first limiting step is formed at the junction of the two.

[0014] The outer diameter of the first arc-shaped piece is equal to the outer diameter of the second engaging piece in the same radial section, where the radial section is perpendicular to the axis of the annular base.

[0015] The length of the first arc-shaped piece is consistent with the thickness of the installed equipment panel.

[0016] Stripes for increasing the friction coefficient are provided on the outer side of the first arc-shaped piece.

[0018] The cavity gradually tapers from the end near the annular base to the end far from the annular base.

[0019] The inner diameter of the clamping foot gradually tapers from the end near the annular base to the end far from the annular base.

[0020] The length of the second engaging piece is 1.5 to 2.5 times that of the first engaging piece.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation manners and specific operation processes are given, but the protection scope of the present invention is not limited to the following embodiments.

[0030] A light-emitting diode fixing structure, comprising:

[0031] Ring-shaped base 1;

[0032] Two first engaging pieces 2, one end of which is fixed to the ring-shaped base 1, and the two first engaging pieces 2 are located at opposite positions on the same side of the ring-shaped base 1, and the first engaging piece 2 is provided with a first limiting step;

[0033] Two second engaging pieces 3, the length of which is greater than that of the first engaging piece 2. Generally, the length of the second engaging piece 3 is 1.5 to 2.5 times that of the first engaging piece 2. The first end of the second engaging piece 3 is fixed to the ring-shaped base 1, and the two first engaging pieces 2 are located at opposite positions on the same side of the ring-shaped base 1, and the second end of the second engaging piece 3 is provided with a clamping foot 3-1 that cooperates with the second limiting step on the light-emitting diode.

[0034] All the first engaging pieces 2 and the second engaging pieces 3 enclose a cavity 4 for accommodating the light-emitting diode. After the light-emitting diode is inserted, relying on the flexibility of the two clamping feet 3-1, the light-emitting diode is clamped tightly and is not easy to fall off.

[0035] Through the design of the two first engaging pieces 2 and the two second engaging pieces 3, on the one hand, the light-emitting diode can be fixed, and on the other hand, it can be reversely fixed on the device panel by relying on the outward supporting force provided by the light-emitting diode to form a firm support, and the longer second engaging piece 3 can also facilitate disassembly, so as to reduce the maintenance cost and improve the fixing effect while saving materials.

[0036] In this embodiment, the projection areas of all the second engaging pieces 3 and the first engaging pieces 2 on the annular base 1 are rotationally symmetric at a 90-degree angle. In this way, the supporting force provided by the cavity 4 is more balanced, which is beneficial to improving the service life under the same material usage. Of course, in other embodiments, it is not limited to this, as long as it satisfies the annular staggered arrangement.

[0037] In all embodiments of the present application, the first engaging piece 2 includes a first arc piece 2-1 and a second arc piece 2-2 arranged along the axis direction of the annular base 1. One end of the first arc piece 2-1 is fixed on the annular base 1, and the other end is connected to one end of the second arc piece 2-2. The outer diameter of the second arc piece 2-2 is larger than that of the first arc piece 2-1, and a first limiting step is formed at the junction of the two. And the first arc piece 2-1 and the second arc piece 2-2 can be integrally formed, so as to improve the structural strength.

[0038] In some embodiments, the outer diameter of the first arc piece 2-1 is equal to the outer diameter of the second engaging piece 3 in the same radial section, where the radial section is perpendicular to the axis of the annular base 1. Based on this, support can be formed with the inner side surface of the mounting hole of the equipment panel from four directions, thereby improving the support effect.

[0039] Normally, the length of the first arc piece 2-1 is consistent with the thickness of the installed equipment panel. However, in actual embodiments, a certain deviation is also allowed. Based on this, stripes for increasing the friction coefficient are provided on the outer side of the first arc piece 2-1, so as to avoid displacement when the deviation is too large. Similarly, stripes for increasing the friction coefficient are provided on the end surface of the second arc piece 2-2 facing the annular base 1, which can also improve the bonding force and avoid displacement.

[0040] In some embodiments, the cavity 4 gradually decreases in size from the end near the annular base 1 to the end far from the annular base 1, so as to form a certain inward moment and improve the stability.

[0041] Generally, the inner diameter of the clamping leg 3-1 gradually decreases from the end near the annular base 1 to the end far from the annular base 1. And in some embodiments, the inner surface of the clamping leg 3-1 is arc-shaped, and in the same radial plane, the inner diameters at both ends are smaller than the inner diameter of the middle part. In this way, stress can be dissipated, thereby improving the service life.

[0042] Install the overall structure of the present application into the mounting hole opened on the equipment panel. From the back of the equipment panel, insert the light-emitting diode. Since the light-emitting diode itself has a step, and the step position just gets stuck at the clamping leg 3-1, firmly fixing the light-emitting diode. The two pins of the light-emitting diode are distributed vertically, which is convenient for subsequent soldering.
