Description

Technical Field

[0001] The utility model relates to the technical field of PCB boards, and specifically relates to a PCB board with long and short gold fingers. Background Art

[0002] The PCB board, also known as the printed circuit board, is an important electronic component, a support for electronic components, and a carrier for the electrical connection of electronic components. A plurality of horizontally arranged conductive contacts are provided at the bottom of the PCB board. Since its surface is gold-plated and the conductive contacts are arranged in a finger shape, it is called a "gold finger".

[0003] Most of the gold fingers on the PCB board are usually nakedly installed on the PCB board. The gold fingers lack protection. When the gold fingers are exposed to the air and come into contact with corrosive substances such as sweat, the gold fingers will be corroded or short-circuited, and there is also a risk of the PCB board being broken, which is not conducive to use. Therefore, a PCB board with long and short gold fingers is proposed to solve the above problems. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a PCB board with long and short gold fingers, which has the advantages of high protection performance and solves the problems of easy corrosion and breakage of the gold fingers.

[0005] To achieve the above object, the utility model provides the following technical solution: A PCB board with long and short gold fingers, including an upper cover, a lower cover is fixed to the bottom of the upper cover, three positioning rods are fixed to the top of the lower cover, a positioning plate is slidably connected to the outer surface of the positioning rod, a positioning block is fixed to the bottom of the upper cover, and a printed circuit board is fixed between the opposite sides of the three positioning plates;

[0006] A gold finger is fixed to the left side of the printed circuit board, a protection component is arranged on the left side of the lower cover and the upper cover, the protection component is used to protect the gold finger, buffer components are arranged on the opposite sides of the upper cover and the lower cover, the buffer components are used to buffer the generated vibration, and a plurality of fixing components are arranged on the outer surfaces of the upper cover and the lower cover, and the fixing components are used to fix the upper cover and the lower cover;

[0007] The protection component includes two support rods, a support block, a support spring, a fixed block and a protection cover. The two support rods are respectively slidably connected to the lower cover and the upper cover. The opposite sides of the two support rods are both fixed to the support block. The opposite sides of the two support blocks are both fixed to the support spring. The two support springs are respectively fixed to the lower cover and the upper cover. The outer surface of the support rod is slidably connected to the fixed block. The left sides of the two fixed blocks are fixed to the protection cover.

[0008] Further, the positioning block is in close fit with the positioning plate. The gold fingers include long fingers and short fingers, and both the long fingers and the short fingers are fixed to the printed circuit board.

[0009] Further, the buffer assembly includes buffer rods respectively fixed to the upper cover and the lower cover. A buffer plate is slidably connected to the outer surface of the buffer rods. Buffer springs fixed to the buffer plate are fixed to one side of the opposite surfaces of the upper cover and the lower cover.

[0010] Further, sliding blocks are fixed to both the left and right sides of the buffer plate. Sliding grooves for slidably connecting with the sliding blocks are formed inside the upper cover and the lower cover.

[0011] Further, sponge pads are fixed to the opposite sides of the two buffer plates. A water-absorbing pad in close fit with the gold fingers is fixed inside the protective cover.

[0012] Further, the fixing assembly includes fixing rods slidably connected to the upper cover and the lower cover. An extrusion block is threadedly connected to the outer surface of the fixing rod.

[0013] Further, the fixing rod is a threaded rod, and a threaded hole adapted to the threaded rod is formed inside the extrusion block.

[0014] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0015] 1. For the PCB board with long and short gold fingers, the protective assembly can protect the gold fingers, thus effectively avoiding corrosion of the gold fingers. When the whole is vibrated, the buffer assembly will buffer the vibration, thereby reducing the damage to the gold fingers and the printed circuit board caused by vibration, effectively improving the overall protection performance, ensuring the safety of the printed circuit board and the gold fingers, and making the whole more practical.

[0016] 2. For the PCB board with long and short gold fingers, the gold fingers respectively control information transmission, power-on and grounding, ensuring the timing difference during the power-on process. The short fingers are powered off first, which can play a protective role. When the long and short gold fingers are inserted and removed, the short fingers contact the power supply slower than the long fingers, which can also play a protective role. Moreover, reducing the length of the gold fingers can also save the consumption of gold and reduce the production cost, thus making the whole more practical. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1-2 , a PCB board with long and short gold fingers in this embodiment includes an upper cover 1. A lower cover 2 is fixed to the bottom of the upper cover 1. Three positioning rods 3 are fixed to the top of the lower cover 2. A positioning plate 4 is slidably connected to the outer surface of the positioning rod 3. The provided positioning plate 4 is used to position the positioning rod 3. A positioning block 5 is fixed to the bottom of the upper cover 1. The positioning block 5 is in close contact with the positioning plate 4. The provided positioning block 5 presses the positioning plate 4, thereby fixing the positioning plate 4 to prevent the positioning plate 4 from separating from the positioning rod 3. A printed circuit board 6 is fixed between the opposite sides of the three positioning plates 4.

[0023] In addition, a gold finger 7 is fixed to the left side of the printed circuit board 6. The gold finger 7 includes long fingers and short fingers. Both the long fingers and the short fingers are fixed to the printed circuit board 6. The gold finger 7 controls information transmission, power-on, and grounding respectively. The long fingers control information transmission and grounding, while the short fingers control power-on. A protection component 8 is provided on the left side of the lower cover 2 and the upper cover 1. The protection component 8 is used to protect the gold finger 7. Buffer components are provided on the opposite sides of the upper cover 1 and the lower cover 2. The buffer components are used to buffer the generated vibration. The buffer components include buffer rods 9 respectively fixed to the upper cover 1 and the lower cover 2. A buffer plate 10 is slidably connected to the outer surface of the buffer rod 9. The provided buffer rod 9 can make the buffer plate 10 slide more stably.

[0024] Furthermore, sliding blocks are fixed on both the left and right sides of the buffer plate 10. Sliding grooves for sliding connection with the sliding blocks are provided inside both the upper cover 1 and the lower cover 2. Buffer springs 11 fixed to the buffer plate 10 are fixed on one side of the back surfaces of the upper cover 1 and the lower cover 2. When the buffer plate 10 moves due to impact, the buffer springs 11 will buffer the impact. A plurality of fixing components are provided on the outer surfaces of the upper cover 1 and the lower cover 2. The fixing components are used to fix the upper cover 1 and the lower cover 2. The fixing components include fixing rods 12 slidably connected to the upper cover 1 and the lower cover 2. An extrusion block 13 is threadedly connected to the outer surface of the fixing rod 12. The fixing rod 12 is a threaded rod, and a threaded hole adapted to the threaded rod is provided inside the extrusion block 13.

[0025] Generally speaking, after the provided fixing rod 12 is slidably connected to the upper cover 1 and the lower cover 2, by rotating the extrusion block 13, the extrusion block 13 can be made to exert extrusion on the upper cover 1, thereby completing the fixation of the upper cover 1 and the lower cover 2, and the extrusion of the positioning block 5 on the positioning plate 4 can be made more stable, making the whole more practical.

[0026] Please refer to Figure 3 , in order to improve the protection performance, the protection component 8 in this embodiment includes two support rods 801, support blocks 802, support springs 803, fixed blocks 804 and a protection cover 805. The two support rods 801 are respectively slidably connected to the lower cover 2 and the upper cover 1. Support blocks 802 are fixed to the opposite sides of the two support rods 801. Support springs 803 are fixed to the opposite sides of the two support blocks 802. The provided support springs 803 can make the limit of the support rods 801 on the fixed blocks 804 more stable.

[0027] Additionally, the two support springs 803 are respectively fixed to the lower cover 2 and the upper cover 1. The outer surface of the support rod 801 is slidably connected to the fixed block 804. The left sides of the two fixed blocks 804 are fixed to the protection cover 805. Sponge pads are fixed to the opposite sides of the two buffer plates 10. A water absorption pad closely attached to the gold finger 7 is fixed inside the protection cover 805. The provided protection cover 805 can protect the gold finger 7, and the provided water absorption pad can effectively prevent the gold finger 7 from being corroded.

[0028] Generally speaking, the provided protection cover 805 can protect the gold finger 7. When in need of use, by pulling the support rod 801, the support rod 801 can be made to lose the plug connection with the fixed block 804, and thus the disassembly of the protection cover 805 can be conveniently completed.

[0029] The working principle of the above embodiment is as follows:

[0030] The provided protective cover 805 can effectively protect the gold fingers 7, thus effectively preventing the gold fingers 7 from being corroded. When in need of use, by pulling the support block 802, the support rod 801 can be made to slide outwards from the fixed block 804, thereby losing the insertion connection with the fixed block 804. At this time, the protective cover 805 can be conveniently pulled to remove the protective cover 805, and then the gold fingers 7 can be connected to the device. When connecting, the gold fingers 7 respectively control information transmission, power-on, and grounding. When the long fingers that control grounding and information transmission are first connected to the device, the last short finger that controls power-on is connected to the device, so as to effectively ensure the stability during connection. The overall structure is simple, effectively improving the overall protection performance, making the whole more practical.
