Description

Technical Field

[0001] The invention relates to the field of LED lighting, in particular to an LED light-emitting module. Background Art

[0002] LED, or light-emitting diode, is a semiconductor device that can convert electrical energy into light energy. It has the characteristics of high efficiency and low energy, high light quality, basically no radiation, high plasticity of the lamp group, and diversified shapes. The core part of the LED is a chip composed of P-type semiconductor and N-type semiconductor. There is a conductive layer on one side of the chip and a bracket attached to the other side. When current acts on the chip through a wire, electrons and holes will be pushed into the quantum well and recombine in the quantum well, and then release energy in the form of photons. This is the principle of LED luminescence.

[0003] During the installation process of LED, the installation of the lamp beads is crucial. LED lamp beads can be installed left and right, up and down, or tilted; different installation methods will produce different lighting effects, including brightness, lamp type, and illumination.

[0004] Existing LED lamp beads are usually installed on circuit boards by means of solder paste. During use and observation, it is found that due to deviations in the installation position, the position of the lamp beads needs to be fine-tuned after being installed on the base on the circuit board, which makes the lamp bead installation steps more cumbersome and reduces the accuracy of the lamp bead installation position.

[0005] Therefore, in order to solve the above problems, an LED light emitting module is proposed. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: an LED light-emitting module described in the present invention comprises a lamp housing; a lampshade is installed on the surface of the lamp housing; a plurality of card blocks are fixedly connected to the inner side wall of the lamp housing; the card block is an L-shaped structure; a circuit board is installed inside the lamp housing; a plurality of lamp beads are installed on the surface of the circuit board; a protective shell is fixedly connected to the middle of the lamp beads; a plurality of positioning rings are fixedly connected to the surface of the circuit board; the positioning ring and the protective shell are correspondingly arranged; a plurality of sliding rods are slidably connected to the middle of the positioning ring; the sliding rod and the positioning ring are through-arranged; a positioning block is fixedly connected to the end of the sliding rod; the surface of the positioning block is inclined; the positioning block is located between the positioning ring and the protective shell; an elastic spring is fixedly connected to the other end of the sliding rod; the elastic spring and the positioning ring are in a fixed relationship; solder paste is applied to the installation position corresponding to the lamp beads on the surface of the circuit board, and then the staff can align the protective shell with the positioning ring and install it, and the protective shell will bring the lamp beads to the circuit board together, and the protective shell will enter the positioning position when it moves. The inner part of the ring contacts with the positioning block. Because the surface of the positioning block is inclined, the protective shell will slide along the surface of the positioning block and continue to approach the circuit board. The positioning block will slide along the positioning ring with the slide rod under the extrusion of the protective shell, and the elastic spring will also be in a stretched state. If there is a deviation in the installation position of the circuit board and the surface of the card block, the stretching lengths between the elastic springs will be different. At this time, the staff can slowly move the protective shell so that the installation position of the protective shell and the lamp beads will be corrected under the extrusion of the positioning block, so that the lamp beads will be accurately installed on the surface of the circuit board. Repeat the above steps until all the lamp beads are installed on the surface of the circuit board, and then the circuit board can be inserted into the interior of the lamp housing through the card block, and then the lamp housing can be closed through the lampshade. Finally, the circuit board can be connected to an external power supply to make the protective shell emit light, and the light will illuminate the outside world through the lampshade; the positioning block will squeeze the protective shell under the elastic force of the elastic spring, so that the device can guide and correct the moving path of the protective shell and the lamp beads when installing, thereby improving the accuracy of the lamp bead installation position.

[0008] Preferably, a plurality of groups of elastic sheets are fixedly connected to the surface of the positioning ring; each group of the elastic sheets and the positioning ring are correspondingly arranged; the positioning ring is located between the protective shell and the elastic sheet; a plurality of pull ropes are fixedly connected between adjacent elastic sheets; when the protective shell and the positioning block come into contact, the positioning block will slide along the positioning ring with the slide bar, at which time the slide bar will approach the elastic sheet and come into contact with the elastic sheet, the elastic sheet will be deformed under the extrusion of the slide bar, and then the elastic sheet will apply elastic force to the slide bar, at which time the positioning block will be subjected to the elastic force applied by the elastic sheet and the elastic spring, so that the protective shell and ... The positioning block in the direction of shell offset will exert a stronger extrusion effect on the protective shell, and at the same time the pull rope will pull the elastic sheet into a whole, thereby improving the stability of the overall structure of the elastic sheet; by setting the elastic sheet, the elastic sheet will exert elastic force on the slide bar and the positioning block, thereby increasing the extrusion effect of the positioning block on the protective shell, enhancing the deviation-correcting effect of the device on the protective shell and the lamp beads, and improving the accuracy of lamp bead installation; at the same time the pull rope will connect the elastic sheet into an integral structure, thereby reducing the extrusion effect on the elastic sheet when the slide bar moves too much, thereby reducing the damage to the elastic sheet caused by excessive deformation, and extending the service life of the elastic sheet.

[0009] Preferably, a plurality of reflective sheets are fixed to the surface of the elastic sheet; the reflective sheet is a multi-faceted structure; when the lamp bead emits light, the light will diffuse in all directions, and these light rays will come into contact with the reflective sheet. Because the surface of the reflective sheet is a multi-faceted structure, the light will be refracted when passing through the reflective sheet, thereby increasing the distribution range of the light emitted by the lamp bead, optimizing the diffusion direction of the light emitted by the device, and enhancing the lighting effect of the device.

[0010] Preferably, a fluorescent ring is fixedly connected to the middle part of the slide rod; the fluorescent ring is a flexible structure; in a normal state, the fluorescent ring will be located inside the positioning ring, and when the lamp beads are installed, the protective shell will squeeze the positioning block and the slide rod, and the slide rod will slide along the positioning ring with the fluorescent ring. When the lamp beads are accurately installed on the surface of the circuit board, all the fluorescent rings will just slide out of the positioning ring and fit tightly against the outer wall of the positioning ring. The staff can quickly determine whether the installation position of the lamp beads is accurate by observing the position of the fluorescent rings, thereby simplifying the detection or debugging required for the device to determine the installation position of the lamp beads, and shortening the working time required for checking the position of the lamp beads.

[0011] Preferably, a top plate is fixedly connected to the bottom of the positioning block; the surface of the top plate is inclined; the top plate and the surface of the positioning block are correspondingly arranged; when the protective shell is installed with the lamp beads, the protective shell will contact the positioning block and the top plate successively, and when the lamp beads are installed on the surface of the card block, the protective shell will contact the inclined surface of the top plate. When the lamp beads need to be removed, the staff can press the elastic sheet so that the elastic sheet squeezes the slide rod and the positioning block. At this time, the top plate will also squeeze the protective shell so that the protective shell will separate from the circuit board with the lamp beads, and the protective shell will slide along the surface of the top plate until it reaches the bottom of the positioning block, and then the protective shell will continue to slide along the surface of the positioning block until the protective shell is separated from the positioning block. At this time, the protective shell and the lamp beads are in an active state, so that the device can quickly disassemble the protective shell and the lamp beads.

[0012] Preferably, a plurality of first fixed grooves are provided in the middle of the block; a plurality of spring telescopic rods are fixedly connected to the inner side walls of the first fixed grooves; the ends of adjacent spring telescopic rods are fixedly connected to a limit plate; the limit plate and the first fixed groove are slidably connected; the limit plate is an arc-shaped structure; when the circuit board is inserted into the interior of the lamp housing along the block, the circuit board will slide along the surface of the block, and the circuit board will come into contact with the limit plate during the movement. After being squeezed, the limit plate will slide along the first fixed groove and put the spring telescopic rod into a compressed state, and then the spring telescopic rod will exert elastic force on the limit plate to make the limit plate approach the circuit board. Because the limit plate is an arc-shaped structure, the circuit board will be close to the inner wall of the lamp housing after passing through the limit plate, and the limit plate will limit the top of the circuit board, so that the circuit board will be squeezed by the block and the limit plate at the same time, thereby improving the stability of the circuit board during operation.

[0013] Preferably, a second fixing groove is provided in the middle of the limiting plate; a pressure block is rotatably connected to the middle of the second fixing groove; a groove is provided on the surface of the pressure block; the groove is a conical structure; when the circuit board comes into contact with the limiting plate, it will also come into contact with the pressure block, and the pressure block will rotate under the extrusion of the circuit board and make the groove face the surface of the circuit board. At this time, the circuit board will come into contact with the inner wall of the groove and the groove will be in an inclined state. Due to the effect of gravity, the circuit board will be squeezed by the pressure block, further improving the stability of the circuit board during installation.

[0014] Preferably, a plurality of buffer pads are fixedly connected to the surface of the groove; the surface of the buffer pad is an arc-shaped structure; when the groove contacts the circuit board, the buffer pad will also contact the circuit board. Because the buffer pad is made of flexible material, when the buffer pad contacts the circuit board, the damage to the circuit board caused by excessive squeezing of the pressure block will be reduced, thereby protecting the circuit board.

[0015] Preferably, the surface of the positioning block is an arc-shaped transition; the positioning block and the slide rod are both arranged in a circular array; because the surface of the positioning block is an arc-shaped transition, the resistance between the positioning block and the protective shell is reduced when the positioning block and the protective shell are in contact, and the wear between the positioning block and the protective shell caused by friction is reduced. At the same time, because the positioning block and the slide rod are both arranged in a circular array, they can better center and correct the protective shell and the lamp bead.

[0016] Preferably, the surface of the card block is an arc-shaped structure; the card block is an L-shaped structure; because the card block is an L-shaped structure and the surface is an arc-shaped structure, the card block can stably limit and clamp the circuit board, and also reduce scratches caused by friction when the circuit board is installed along the card block.

[0017] The present invention is beneficial in that:

[0018] 1. In the LED light-emitting module described in the present invention, the positioning block will squeeze the protective shell under the elastic force of the elastic spring, so that the device can guide and correct the moving path of the protective shell and the lamp beads during installation, thereby improving the accuracy of the installation position of the lamp beads.

[0019] 2. The LED light-emitting module described in the present invention has an elastic sheet, which applies elastic force to the slide bar and the positioning block, thereby increasing the squeezing effect of the positioning block on the protective shell, enhancing the correcting effect of the device on the protective shell and the lamp beads, and improving the accuracy of lamp bead installation. At the same time, the pull rope connects the elastic sheet into an integral structure, reducing the squeezing effect of the elastic sheet when the slide bar moves too much, reducing the damage to the elastic sheet caused by excessive deformation, and extending the service life of the elastic sheet.

And it contacts with the positioning block 17. Because the surface of the positioning block 17 is inclined, the protective shell 15 will slide along the surface of the positioning block 17 and continue to approach the circuit board 14. The positioning block 17 will slide along the positioning ring 16 with the slide bar 18 under the extrusion of the protective shell 15, and the elastic spring 19 will also be in a stretched state. If there is a deviation in the installation position of the circuit board 14 and the surface of the card block 13, the stretching length of the elastic spring 19 will be different. At this time, the staff can slowly move the protective shell 15, so that the installation position of the protective shell 15 and the lamp bead 110 will be corrected under the extrusion of the positioning block 17, so that the lamp bead 110 0 will be accurately installed on the surface of the circuit board 14, and the above steps are repeated until all the lamp beads 110 are installed on the surface of the circuit board 14. Then the circuit board 14 can be inserted into the interior of the lamp housing 1 through the clamping block 13, and then the lamp housing 1 is closed through the lampshade 12. Finally, the circuit board 14 is connected to an external power source to make the protective shell 15 emit light, and the light will illuminate the outside through the lampshade 12; the positioning block 17 will squeeze the protective shell 15 under the elastic force of the elastic spring 19, so that the device can guide and correct the moving path of the protective shell 15 and the lamp beads 110 when installing, thereby improving the accuracy of the installation position of the lamp beads 110.

[0033] See also Figure 2 and Figure 4As shown, the surface of the positioning ring 16 is fixed with multiple groups of elastic sheets 2; each group of the elastic sheets 2 and the positioning ring 16 are correspondingly arranged; the positioning ring 16 is located between the protective shell 15 and the elastic sheet 2; multiple pull ropes 22 are fixedly connected between adjacent elastic sheets 2; when the protective shell 15 and the positioning block 17 come into contact, the positioning block 17 will slide along the positioning ring 16 with the slide bar 18, at this time the slide bar 18 will approach the elastic sheet 2 and come into contact with the elastic sheet 2, the elastic sheet 2 will be deformed under the squeezing action of the slide bar 18, and then the elastic sheet 2 will apply elastic force to the slide bar 18, at this time the positioning block 17 will be subjected to the elastic force applied by the elastic sheet 2 and the elastic spring 19, so that the protective shell 15 and ... The positioning block 17 in the offset direction of the protective shell 15 will exert a stronger extrusion effect on the protective shell 15, and at the same time, the pull rope 22 will pull the elastic sheet 2 into a whole, thereby improving the stability of the overall structure of the elastic sheet 2; by setting the elastic sheet 2, the elastic sheet 2 will exert elastic force on the slide bar 18 and the positioning block 17, thereby increasing the extrusion effect of the positioning block 17 on the protective shell 15, enhancing the deviation correction effect of the device on the protective shell 15 and the lamp bead 110, and improving the accuracy of the installation of the lamp bead 110; at the same time, the pull rope 22 will connect the elastic sheet 2 into an integral structure, thereby reducing the extrusion effect of the slide bar 18 on the elastic sheet 2 when the movement range is too large, thereby reducing the damage to the elastic sheet 2 caused by excessive deformation, and extending the service life of the elastic sheet 2.

[0034] See also Figure 3 and Figure 4 As shown, a plurality of reflective sheets 3 are fixedly connected to the surface of the elastic sheet 2; the reflective sheet 3 is a multi-faceted structure; when the lamp bead 110 emits light, the light will diffuse in all directions, and these light will come into contact with the reflective sheet 3. Because the surface of the reflective sheet 3 is a multi-faceted structure, the light will be refracted when passing through the reflective sheet 3, thereby increasing the distribution range of the light emitted by the lamp bead 110, optimizing the diffusion direction of the light emitted by the device, and enhancing the lighting effect of the device.

[0035] See also Figure 5 As shown, a fluorescent ring 4 is fixedly connected to the middle part of the slide bar 18; the fluorescent ring 4 is a flexible structure; in a normal state, the fluorescent ring 4 will be located inside the positioning ring 16, and when the lamp bead 110 is installed, the protective shell 15 will squeeze the positioning block 17 and the slide bar 18, and the slide bar 18 will slide along the positioning ring 16 with the fluorescent ring 4. When the lamp bead 110 is accurately installed on the surface of the circuit board 14, all the fluorescent rings 4 will just slide out of the positioning ring 16 and cling to the outer wall of the positioning ring 16. The staff can quickly determine whether the installation position of the lamp bead 110 is accurate by observing the position of the fluorescent ring 4, simplifying the detection or debugging required for the device to determine the installation position of the lamp bead 110, and shortening the working time required for checking the position of the lamp bead 110.

[0036] See also Figure 5As shown, a top plate 5 is fixedly connected to the bottom of the positioning block 17; the surface of the top plate 5 is inclined; the top plate 5 and the surface of the positioning block 17 are correspondingly arranged; when the protective shell 15 is installed with the lamp bead 110, the protective shell 15 will contact the positioning block 17 and the top plate 5 successively, and when the lamp bead 110 is installed on the surface of the block 13, the protective shell 15 will contact the inclined surface of the top plate 5. When the lamp bead 110 needs to be disassembled, the staff can press the elastic sheet 2 so that the elastic sheet 2 squeezes the slide bar 18 and the positioning block 17.

At this time, the protective shell 15 and the lamp bead 110 are in an active state, realizing the rapid disassembly of the protective shell 15 and the lamp bead 110 by the device.

[0037] See also Figures 6 to 8 As shown, a plurality of first fixing grooves 6 are provided in the middle of the block 13; a plurality of spring telescopic rods 62 are fixedly connected to the inner side wall of the first fixing groove 6; the ends of the adjacent spring telescopic rods 62 are fixedly connected to the limiting plates 63; the limiting plates 63 and the first fixing groove 6 are slidably connected; the limiting plates 63 are arc-shaped structures; when the circuit board 14 is inserted into the lamp housing 1 along the block 13, the circuit board 14 will slide along the surface of the block 13, and the circuit board 14 will contact the limiting plates 63 during the movement, and the limiting plates 63 will be moved. After being squeezed, it will slide along the first fixing groove 6 and make the spring telescopic rod 62 in a compressed state. Then, the spring telescopic rod 62 will apply elastic force to the limiting plate 63 to make the limiting plate 63 close to the circuit board 14. Because the limiting plate 63 is an arc-shaped structure, the circuit board 14 will be close to the inner wall of the lamp housing 1 after passing through the limiting plate 63. The limiting plate 63 will limit the top of the circuit board 14, so that the circuit board 14 will be squeezed by the block 13 and the limiting plate 63 at the same time, thereby improving the stability of the circuit board 14 during operation.

[0038] See also Figure 8 As shown, a second fixing groove 7 is provided in the middle of the limiting plate 63; a pressure block 72 is rotatably connected to the middle of the second fixing groove 7; a groove 73 is provided on the surface of the pressure block 72; the groove 73 is a conical structure; when the circuit board 14 comes into contact with the limiting plate 63, it will also come into contact with the pressure block 72, and the pressure block 72 will rotate under the extrusion of the circuit board 14 and make the groove 73 face the surface of the circuit board 14.

[0040] See also Figure 5 As shown, the surface of the positioning block 17 is an arc-shaped transition; the positioning block 17 and the slide bar 18 are both arranged in a circular array; because the surface of the positioning block 17 is an arc-shaped transition, the resistance between the positioning block 17 and the protective shell 15 is reduced when the positioning block 17 and the protective shell 15 are in contact, and the wear between the positioning block 17 and the protective shell 15 caused by friction is reduced. At the same time, because the positioning block 17 and the slide bar 18 are both arranged in a circular array, they can better center and correct the protective shell 15 and the lamp bead 110.

[0041] See also Figure 7 As shown, the surface of the block 13 is an arc-shaped structure; the block 13 is an L-shaped structure; because the block 13 is an L-shaped structure and the surface is an arc-shaped structure, the block 13 can stably limit and clamp the circuit board 14, and also reduce scratches caused by friction when the circuit board 14 is installed along the block 13.

[0042] Working principle: Apply solder paste to the installation position corresponding to the lamp bead 110 on the surface of the circuit board 14, and then the staff can align the protective shell 15 with the positioning ring 16 for installation. The protective shell 15 will bring the lamp bead 110 closer to the circuit board 14. When the protective shell 15 moves, it will enter the inside of the positioning ring 16 and contact the positioning block 17. Because the surface of the positioning block 17 is inclined, the protective shell 15 will slide along the surface of the positioning block 17 and continue to approach the circuit board 14. The positioning block 17 will slide along the positioning ring 16 with the slide bar 18 under the extrusion of the protective shell 15, and the elastic spring 19 will also be in a stretched state. If the circuit board 14 and the block 13 are installed on the surface If there is a deviation in the position, the stretching lengths of the elastic springs 19 will be different. At this time, the staff can slowly move the protective shell 15, so that the installation positions of the protective shell 15 and the lamp beads 110 will be corrected under the squeezing action of the positioning block 17, so that the lamp beads 110 will be accurately installed on the surface of the circuit board 14, and the above steps are repeated until all the lamp beads 110 are installed on the surface of the circuit board 14. Then, the circuit board 14 can be inserted into the interior of the lamp housing 1 through the clamping block 13, and then the lamp housing 1 can be closed through the lampshade 12. Finally, the circuit board 14 is connected to an external power supply to make the protective shell 15 emit light, and the light will illuminate the outside world through the lampshade 12; the protective shell 15 and the positioning block 17 are pressed and adjusted. When the block 17 comes into contact, the positioning block 17 will slide along the positioning ring 16 with the sliding rod 18. At this time, the sliding rod 18 will approach the elastic sheet 2 and come into contact with the elastic sheet 2. The elastic sheet 2 will be deformed under the squeezing action of the sliding rod 18. Then the elastic sheet 2 will apply elastic force to the sliding rod 18. At this time, the positioning block 17 will be subjected to the elastic force applied by the elastic sheet 2 and the elastic spring 19, so that the positioning block 17 in the offset direction of the protective shell 15 will apply a stronger squeezing action to the protective shell 15. At the same time, the pull rope 22 will tie the elastic sheet 2 into a whole, thereby improving the stability of the overall structure of the elastic sheet 2. By setting the elastic sheet 2, the elastic sheet 2 will exert an elastic force on the sliding rod 18 and the positioning block 17. Add elastic force, increase the squeezing effect of the positioning block 17 on the protective shell 15, enhance the correction effect of the device on the protective shell 15 and the lamp bead 110, and improve the accuracy of the installation of the lamp bead 110. At the same time, the pull rope 22 will connect the elastic sheet 2 into an integral structure, reduce the squeezing effect on the elastic sheet 2 when the slide bar 18 moves too much, and reduce the damage caused by excessive deformation of the elastic sheet 2; when the lamp bead 110 emits light, the light will diffuse to the surroundings, and these lights will come into contact with the reflective sheet 3. Because the surface of the reflective sheet 3 is a multi-faceted structure, the light will be refracted when passing through the reflective sheet 3, increasing the distribution range of the light emitted by the lamp bead 110 and optimizing the diffusion direction of the light emitted by the device;In a normal state, the fluorescent ring 4 will be located inside the positioning ring 16. When the lamp bead 110 is installed, the protective shell 15 will squeeze the positioning block 17 and the slide bar 18, and the slide bar 18 will slide along the positioning ring 16 with the fluorescent ring 4. When the lamp bead 110 is accurately installed on the surface of the circuit board 14, all the fluorescent rings 4 will just slide out of the positioning ring 16 and cling to the outer wall of the positioning ring 16. The staff can quickly determine whether the installation position of the lamp bead 110 is accurate by observing the position of the fluorescent ring 4, simplifying the detection or debugging required for the device to determine the installation position of the lamp bead 110; when the protective shell 15 is installed with the lamp bead 110, the protective shell 15 will contact the positioning block 17 and the top plate 5 successively. When the lamp bead 110 is installed on the surface of the card block 13 When the protective shell 15 is in contact with the inclined surface of the top plate 5, when the lamp bead 110 needs to be disassembled, the staff can press the elastic sheet 2 so that the elastic sheet 2 squeezes the sliding rod 18 and the positioning block 17. At this time, the top plate 5 will also squeeze the protective shell 15 so that the protective shell 15 will separate from the circuit board 14 with the lamp bead 110, and the protective shell 15 will slide along the surface of the top plate 5 until it reaches the bottom of the positioning block 17, and then the protective shell 15 will continue to slide along the surface of the positioning block 17 until the protective shell 15 is separated from the positioning block 17. At this time, the protective shell 15 and the lamp bead 110 are in an active state; when the circuit board 14 is inserted into the interior of the lamp housing 1 along the card block 13, the circuit board 14 will slide along the surface of the card block 13, and the circuit board 14 will move during the movement. 14 will come into contact with the limiting plate 63. After being squeezed, the limiting plate 63 will slide along the first fixed groove 6 and compress the spring telescopic rod 62. Then, the spring telescopic rod 62 will apply elastic force to the limiting plate 63 to make the limiting plate 63 approach the circuit board 14. Because the limiting plate 63 is an arc-shaped structure, the circuit board 14 will be close to the inner wall of the lamp housing 1 after passing through the limiting plate 63. The limiting plate 63 will limit the top of the circuit board 14, so that the circuit board 14 will be squeezed by the block 13 and the limiting plate 63 at the same time; when the circuit board 14 comes into contact with the limiting plate 63, it will also come into contact with the pressing block 72. The pressing block 72 will rotate under the squeezing action of the circuit board 14 and make the groove 73 face the surface of the circuit board 14. When the circuit board 14 contacts the inner wall of the groove 73 and the groove 73 is in an inclined state, the circuit board 14 will be squeezed by the pressing block 72 due to gravity; when the groove 73 contacts the circuit board 14, the buffer pad 8 will also contact the circuit board 14, because the buffer pad 8 is a flexible material, so that when the buffer pad 8 contacts the circuit board 14, the damage caused by excessive squeezing of the pressing block 72 on the circuit board 14 will be reduced; because the surface of the positioning block 17 is an arc transition, when the positioning block 17 contacts the protective shell 15, the resistance between the positioning block 17 and the protective shell 15 is reduced, and the wear caused by friction between the positioning block 17 and the protective shell 15 is reduced, and at the same time, because the positioning block 17 and the sliding rod 18 are both arranged in a circular array;Because the block 13 is an L-shaped structure and the surface is an arc-shaped structure, the block 13 can stably limit and clamp the circuit board 14, and also reduce the scratches caused by friction when the circuit board 14 is installed along the block 13. ;
