Description

Technical Field

[0001] This utility model relates to the field of light guide column technology, and more specifically, to a light guide column mounting base. Background Technology

[0002] A light guide column is a structure attached to a circuit board to reflect and amplify the light source on the circuit board.

[0003] The existing light guide pillars are inserted into the circuit board via pins. However, the diameter of the existing light guide pillar pins is fixed and rigid. If there is an error between the diameter of the light guide pillar pins and the hole, the light guide pillar pins may not be able to be inserted into the hole or may not be able to be securely connected to the hole, thus affecting the connection of the light guide pillar. Utility Model Content

[0004] The purpose of this utility model is to provide a light guide post mounting foot, which solves the problem that the light guide post foot cannot be adapted to larger holes due to its rigid design and fixed diameter, resulting in low versatility.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model provides a light guide post mounting base, including a light guide post, a base at the bottom of the light guide post, a base at the bottom of the base, a pressing slope at the bottom of the base, a pressing gap in the middle of the base, a friction ring on the side wall of the base, and a shrinkage component on the side wall of the friction ring, which is displaced under pressure.

[0007] Preferably, the extrusion slope is a surface with a circular arc at the bottom of the column base.

[0008] Preferably, the compression gap is an opening that runs through the middle of the column base.

[0009] Preferably, the extrusion gap further includes a gap support block, which is disposed at the top of the middle part of the extrusion gap.

[0010] Preferably, the gap support block is a square block located at the top of the middle of the extrusion gap.

[0011] Preferably, the friction ring is provided on several annular protrusions on the side wall of the column foot, and the side wall of the column foot where the friction ring is provided is an annular groove.

[0012] Preferably, the shrinkage assembly includes a shrinkage groove, an extrusion block, and an extrusion ramp. The shrinkage groove is disposed on the side wall of the friction ring, the extrusion block is connected to the middle of the shrinkage groove, and the extrusion ramp is disposed on the upper and lower sides of the extrusion block.

[0013] Preferably, one end of the extrusion block mates with the shrinkage groove, and one end of the extrusion block is connected to one end of the middle of the shrinkage groove via a spring.

[0014] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0015] 1. The compression gap in the device allows the column to tilt and deform towards the gap, thus allowing it to be inserted into the hole of the circuit board. Then, due to the force generated by the reset, it will fit tightly against the inner wall of the hole for a stable connection.

[0016] 2. The device is also equipped with a shrinking component. When the column base is being removed, if the part of the column base protruding from the bottom of the hole cannot be lifted due to resetting and pressing against the opening of the hole, the shrinking component will facilitate separation into the hole.

[0021] The following is combined Figures 1 to 3 This utility model will be described in detail.

[0022] A light guide post mounting base includes a light guide post 1, a base 101 at the bottom of the light guide post 1, a base 2 at the bottom of the base 101, a pressing inclined surface 201 at the bottom of the base 2, a pressing gap 202 in the middle of the base 2, a friction ring 203 on the side wall of the base 2, and a shrinking component on the side wall of the friction ring 203. The shrinking component is displaced under pressure. The pressing inclined surface 201 is an arc-shaped surface at the bottom of the base 2. The pressing gap is an opening that passes through the middle of the base 2. The pressing gap 202 also includes a gap support block 2021, which is a square block located at the top of the middle of the pressing gap 202. The friction ring 203 has several annular protrusions on the side wall of the base 2, and the side wall of the base 2 with the friction ring 203 is an annular groove.

[0023] First, the light guide post 1 is inserted into the hole on the circuit board through the post 2 on the bottom base 101. The light guide post 1 is connected to the circuit board, and the light source generated on the circuit board is refracted and magnified, making it more clearly observable.

[0024] When the pin 2 is inserted into the circuit board hole for connection, the pressing bevel 201 at the bottom of the pin 2 will contact the inner wall of the hole opening. Then, when the pin 2 is pressed, it will be guided by the pressing bevel 201 to close and tilt towards the pressing gap 202, allowing the pin 2 to be inserted into the circuit board hole. At the same time, the elastic reset of the pin 2 itself will make the pin 2 fit tightly against the inner wall of the circuit board hole, so that the pin 2 can be quickly and stably connected to the circuit board hole.

[0025] Meanwhile, by setting a friction ring 203 in the annular groove on the inner wall of the column foot 2 to replace the contact with the inner wall of the circuit board hole, the friction between the column foot 2 and the inner wall of the circuit board hole is reduced, so that when inserting and removing, it will not be difficult to disassemble or assemble due to excessive friction from full contact.

[0026] A gap support block 2021 is also provided at the top of the compression gap 202. The gap support block 2021 can prevent the deformation of the column foot 2 caused by the compression gap 202 from being too large and breaking.

[0027] Furthermore, the shrinkage assembly includes a shrinkage groove 2031, an extrusion block 2032, and an abutment inclined surface 2033. The shrinkage groove 2031 is disposed on the side wall of the friction ring 203. The extrusion block 2032 is connected to the middle of the shrinkage groove 2031. The abutment inclined surface 2033 is disposed on the upper and lower sides of the extrusion block 2032. One end of the extrusion block 2032 cooperates with the shrinkage groove 2031. One end of the extrusion block 2032 is connected to one end of the middle of the shrinkage groove 2031 by a spring.

[0028] The friction ring 203 on the side wall of the column base 2 is fitted to the inner wall of the hole by the extrusion block 2032 connected by the shrinkage groove 2031.

[0029] Meanwhile, when the pin 2 is fully inserted into the circuit board hole and needs to be removed, if the circuit board is thin, most of the pin 2 will be exposed at the bottom of the circuit board. When the pin 2 is lifted, if the top of the friction ring 203 on the side wall of the pin 2 abuts against the bottom opening of the circuit board hole, it will contact the bottom opening of the circuit board hole through the compression block 2032 connected to the shrinkage groove 2031 on the side wall of the friction ring 203. Then, through the abutting slope 2033 of the compression block 2032, the compression block 2032 will shrink into the shrinkage groove 2031 when it abuts, compressing the spring, so that the friction ring 203 will not be unable to lift due to the elastic reset of the pin 2.

[0030] The following is a detailed implementation process of this utility model. First, the light guide post 1 is inserted into the hole of the circuit board through the post 2 on the bottom base 101. By connecting the light guide post 1 to the circuit board, the light source generated on the circuit board is refracted and magnified. It can be more clearly observed that when the post 2 is inserted into the hole of the circuit board for connection, the pressing slope 201 at the bottom of the post 2 will contact the inner wall of the hole opening. Then, when the post 2 is pressed, it will be guided by the pressing slope 201 to close and tilt towards the pressing gap 202, allowing the post 2 to be inserted into the hole of the circuit board. At the same time, the elasticity of the post 2 itself... The positioning mechanism allows the pin 2 to fit tightly against the inner wall of the circuit board hole, enabling the pin 2 to connect quickly and stably to the circuit board hole. Simultaneously, a friction ring 203 is provided in the annular groove on the inner wall of the pin 2 to replace direct contact with the inner wall of the circuit board hole, reducing friction between the pin 2 and the inner wall of the circuit board hole. This prevents excessive friction during insertion and removal, avoiding difficulties in assembly and disassembly. A gap support block 2021 is also provided at the top of the compression gap 202, preventing the pin 2 from deforming excessively through the compression gap 202 and breaking.

[0031] The friction ring 203 on the side wall of the column 2 fits against the inner wall of the hole through the compression block 2032 connected by the shrinkage groove 2031. When the column 2 is fully inserted into the hole of the circuit board and needs to be removed, if the thickness of the circuit board is small, most of the column 2 will be exposed at the bottom of the circuit board. When the column 2 is lifted, if the top of the friction ring 203 on the side wall of the column 2 abuts against the bottom opening of the hole of the circuit board, it will contact and abut against the bottom opening of the hole of the circuit board through the compression block 2032 connected by the shrinkage groove 2031 on the side wall of the friction ring 203. Then, through the abutting slope 2033 of the compression block 2032, the compression block 2032 retracts into the shrinkage groove 2031 when it abuts against the spring, so that the friction ring 203 will not be unable to lift due to the elastic reset of the column 2.
