[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0041] This invention provides a PCB component. Figure 1 This is a left view of a PCB component provided in an embodiment of the present invention. Figure 2 This is a right view of the PCB component provided in an embodiment of the present invention. Figure 3 This is another left view of the PCB plug-in provided in this embodiment of the invention.

See also... Figures 1-6 The PCB assembly includes: a first protection board 101, a second protection board 102, a third protection board 103, a fourth protection board 104, a PCB board 105, and circuit components 106.

[0042] The surface of the first protective plate 101 is provided with a plurality of support pillars 1010, and the PCB board 105 is fixedly connected to the support pillars 1010; the PCB board 105 is provided with a plurality of first through holes 1051, and the circuit element 106 is provided on the side of the PCB board 105 away from the first protective plate 101. The circuit element 106 includes a protrusion 1061, which penetrates through the first through hole 1051 and contacts the first protective plate 101, and the protrusion 1061 is fixedly connected to the first protective plate 101; the second protective plate 105 is provided with a plurality of support pillars 1010, and the PCB board 105 is fixedly connected to the first protective plate 101; the second protective plate 105 is fixedly connected to the first protective plate 101, and the PCB board 105 is fixedly connected to the The protective plate 102 is located on the side of the circuit element 106 away from the PCB board 105. The second protective plate 102 is fixedly connected to the circuit element 106. The third protective plate 103 and the fourth protective plate 104 are arranged opposite to each other. The third protective plate 103 and the fourth protective plate 104 are both fixedly connected to the first protective plate 101 and the second protective plate 102. The first protective plate 101, the second protective plate 102, the third protective plate 103 and the fourth protective plate 104 form a housing. The PCB board 105 is located inside the housing.

[0043] Specifically, the support post 1010 can be a press-fit stud. The PCB board 105 can be fixedly connected to the support post 1010 on the first protection plate 101 by screws. Then, the protrusion 1061 on the circuit element 106 passes through the corresponding first through hole 1051 on the PCB board 105 and is fastened to the first protection plate 101. Then, the flying wire led out from the circuit element 106 is connected to the terminal on the PCB board 105. After connecting the flying wire, the second protection plate 102 is installed by screws to tightly connect the circuit element 106 with the first protection plate 101 and the second protection plate 102. Next, the third protection plate 103 is installed in the upper gap formed by the first protection plate 101 and the second protection plate 102, and the fourth protection plate 104 is installed in the lower gap formed by the first protection plate 101 and the second protection plate 102. The first protection plate 101, the second protection plate 102, the third protection plate 103 and the fourth protection plate 104 form a structurally stable enclosure, and the PCB board 105 and circuit components 106 are fixed inside the enclosure.

[0044] In the PCB plug-in provided by this embodiment of the invention, the first protection plate 101, the second protection plate 102, the third protection plate 103, and the fourth protection plate 104 form a stable housing structure. The PCB board 105 and the circuit element 106 are fixed inside the housing. The first protection plate 101, the second protection plate 102, the third protection plate 103, and the fourth protection plate 104 protect the PCB board 105 and the circuit element 106, preventing damage to the PCB board 105 and the circuit element 106 during insertion and removal. This improves the safety and reliability during installation. Furthermore, the PCB board 105 is floated between the first protection plate 101 and the second protection plate 102. Through the coordinated action of the first protection plate 101 and the second protection plate 102, the heavier circuit element 106 is clamped and fixed, so that the PCB board 105 is not subjected to the force of the circuit element 106, avoiding deformation of the PCB board 105 and improving the structural stability of the PCB plug-in.

[0045] Continue to refer to Figure 2 and Figure 3 Optionally, the third protection plate 103 is disposed between the first protection plate 101 and the second protection plate 102, and the edges of the ends of the first protection plate 101 and the second protection plate 102 connected to the third protection plate 103 are all higher than the surface of the third protection plate 103 away from the PCB board 105.

[0046] The fourth protection plate 104 is disposed between the first protection plate 101 and the second protection plate 102, and the edges of the ends of the first protection plate 101 and the second protection plate 102 that are connected to the fourth protection plate 104 are all higher than the surface of the fourth protection plate 104 that is away from the PCB board 105.

[0047] The portions of the first and second protection plates 101 and 102 that connect to the third protection plate 103, extending above the third protection plate 103, can serve as slideways that mate with the guide rails 201 in the PCB insertion box 200. PCB components are slid into the guide rails 201 in the PCB insertion box 200 via these portions. Similarly, the portions of the first and second protection plates 101 and 102 that connect to the fourth protection plate 104, extending above the fourth protection plate 104, can also serve as slideways that mate with the guide rails 201 in the PCB insertion box 200. PCB components are slid into the guide rails 201 in the PCB insertion box 200 via these portions.

[0048] Figure 7 This is a schematic diagram of the guide rail structure in the insertion box provided in an embodiment of the present invention. Figure 8 This is a left view of the PCB plug-in provided in the embodiment of the present invention in the insertion box. Figure 9 This is a right view of the PCB component provided in the embodiment of the present invention in the insertion box, for reference. Figure 7 , Figure 8 and Figure 9 The installed PCB plug-in is slid into the guide rail 201 in the insertion box 200 via the top and bottom edges of the first protection board 101 and the second protection board 102. The PCB board 105 then connects to the mother PCB in the insertion box 200 via the connector at the tail, thus enabling communication. By using the two edges of the first protection board 101 and the second protection board 102 to slide into the guide rail 201 in the insertion box 200, instead of the original PCB board 105 directly sliding into the guide rail 201, the overall structure of the PCB plug-in is kept stable. This design improves installation reliability and prevents damage to the PCB board from forceful insertion or removal.

[0049] Continue to refer to Figures 1-6 Optionally, the first protection board 101 includes a first region 1011, a second region 1012 and a third region 1013. The second region 1012 is located between the first region 1011 and the third region 1013. The distance between the second region 1012 and the PCB board 105 is less than the distance between the first region 1011 and the third region 1013 and the PCB board 105, and the distance between the second region 1012 and the PCB board 105 is greater than zero. The protrusion of the circuit element 106 contacts the second region 1012.

[0050] The second protection board 102 includes a fourth region 1021, a fifth region 1022 and a sixth region 1023. The fifth region 1022 is located between the fourth region 1021 and the sixth region 1023. The distance between the fifth region 1022 and the PCB board 105 is greater than the distance between the fourth region 1021 and the sixth region 1023 and the PCB board 105. The fifth region 1022 of the second protection board 102 is fixedly connected to the circuit element 106.

[0051] The third protective plate 103 is fixed between the first region 1011 of the first protective plate 101 and the fourth region 1021 of the second protective plate 102, and the fourth protective plate 104 is fixed between the third region 1013 of the first protective plate 101 and the sixth region 1023 of the second protective plate 102.

[0052] The PCB board 105 has multiple first through holes 1051. The protrusions 1061 of the circuit element 106 pass through the first through holes 1051 of the PCB board 105 and contact the second region 1012. Screws can be used to fix the protrusions 1061 of the circuit element 106 to the first protective plate 101. Screws can also be used to fix the fifth region 1022 of the second protective plate 102 to the circuit element 106. The above connection method makes the first protective plate 101, PCB board 105, circuit element 106 and second protective plate 102 form a whole. The third protective plate 103 and the fourth protective plate 104 are respectively fixed in the gaps formed on the upper and lower sides of the first protective plate 101 and the second protective plate 102, thus forming a box-like structure and improving overall stability.

[0053] By setting the distance between the second region 1012 and the PCB board 105 to be smaller than the distance between the first region 1011 and the third region 1013 and the PCB board 105, the distance between the circuit element 106 and the first protection plate 101 is smaller, so that the protrusion 1061 on the circuit element 106 does not need to be made too high to affect the structural strength.

[0054] It should be noted that the distance between the first region 1011 of the first protection plate 101 and the fourth region 1021 of the second protection plate 102, as well as the distance between the third region 1013 of the first protection plate 101 and the sixth region 1023 of the second protection plate 102, are all equal to the width of the guide rail on the insertion box.

[0055] Continue to refer to Figure 4 and Figure 5 Optionally, the first region 1011 and the third region 1013 of the first protective plate 101 are each provided with a plurality of first support columns 1010A, and the second region 1012 is provided with a plurality of second support columns 1010B. The surfaces of the first support columns 1010A and the second support columns 1010B are flush with the surfaces of the first protective plate 101.

[0056] Each region of the first protective plate 101 has a support column 1010, which includes a first support column 1010A and a second support column 1010B. Multiple first support columns 1010A are evenly distributed in the first region 1011 and the third region 1013, and multiple second support columns 1010B are evenly distributed in the second region 1012. Both the first support columns 1010A and the second support columns 1010B are used to support the PCB board 105, making the force on the PCB board 105 more even and avoiding stress concentration that could damage the PCB board.

[0057] It should be noted that the heights of the first support column 1010A and the second support column 1010B can be set as needed, and this embodiment does not impose a specific limitation. For example, the height of the first support column 1010A can be 5.5cm, and the height of the second support column 1010B can be 11.5cm. The number of support columns 1010 in the first region 1011, the second region 1012, and the third region 1013 can be set as needed. For example, the first region 1011 can have 4 first support columns 1010A, the second region 1012 can have 3 second support columns 1010B, and the third region 1013 can have 4 first support columns 1010A.

[0058] Continue to refer to Figures 1-6 Optionally, threaded holes are provided on the surfaces of the first support column 1010A and the second support column 1010B away from the first protection plate 101, and the PCB board 105 is fixedly connected to the first support column 1010A and the second support column 1010B by screws; threaded holes are provided on the protrusion 1061, and the first protection plate 101 and the protrusion 1061 are fixedly connected by screws; the second protection plate 102 is fixedly connected to the circuit element 106 by screws.

[0059] During assembly, firstly, the first protective plate 101 is placed horizontally, with the first support pillar 1010A and the second support pillar 1010B protruding upwards. Threaded holes are provided on the surfaces of the first support pillar 1010A and the second support pillar 1010B. Screws are used to fix the PCB board 105 to the first support pillar 1010A and the second support pillar 1010B, and the screws are tightened. Next, the protrusion 1061 of the circuit element 106 is passed through the PCB board 105. The protrusion 1061 of the circuit element 106 has threaded holes, and screws are used to fix the first protective plate 101 and the protrusion 1061 of the circuit element 106 together. Finally, screws are used to fix the circuit element 106 to the second protective plate 102. The PCB board 105 is suspended between the first protection plate 101 and the second protection plate 102. The first protection plate 101 and the second protection plate 102 clamp and fix the heavier circuit component 106, so that the PCB board 105 is not subjected to force and avoids deformation during insertion and removal.

[0060] It should be noted that during the installation of circuit components 106, each time a circuit component 106 is installed, its jumper wire must be connected to the corresponding terminal on the PCB board 105.

[0061] Optionally, the second region 1012 is provided with a plurality of second through holes 112. The regions of the first protective plate 101 and the second protective plate 102 adjacent to the third protective plate 103 are each provided with a plurality of third through holes 113, which are arranged sequentially along the extending direction of the edge connecting the third protective plate 103 and the first protective plate 101; and / or, the regions of the first protective plate 101 and the second protective plate 102 adjacent to the fourth protective plate 104 are each provided with a plurality of fourth through holes 114, which are arranged sequentially along the extending direction of the edge connecting the fourth protective plate 104 and the first protective plate 101.

[0062] The second through-hole 112 reduces the weight of the first protective plate 101, thereby reducing the weight of the PCB components, facilitating assembly, and improving installation efficiency. For example, the second through-hole 112 in the second region 1012 of the first protective plate 101 can be racetrack-shaped, with a length × width of 50mm × 15mm. Multiple third through-holes 113 and fourth through-holes 114 can be arranged sequentially, with a diameter of 20mm. The third and fourth through-holes 113 and 114 reduce the weight of the first and second protective plates 101 and 102, increasing strength, facilitating assembly and carrying, and improving installation efficiency. For example, the third and fourth through-holes 113 and 114 can be circular holes with a diameter of 20mm.

[0063] Continue to refer to Figure 2 and Figure 3Optionally, the third protective plate 103 includes a plurality of first strip-shaped through holes 1031, the first strip-shaped through holes 1031 extending along the direction from the first protective plate 101 to the second protective plate 102, and the plurality of first strip-shaped through holes 1031 arranged sequentially along the extension direction of the side connecting the third protective plate 103 and the first protective plate 101.

[0064] The fourth protective plate 104 includes a plurality of second strip-shaped through holes 1041. The second strip-shaped through holes 1041 extend along the direction from the first protective plate 101 to the second protective plate 102. The plurality of second strip-shaped through holes 1041 are arranged sequentially along the extension direction of the side connecting the fourth protective plate 104 and the first protective plate 101.

[0065] The first strip-shaped through hole 1031 and the second strip-shaped through hole 1041 are distributed sequentially. The specific number of strip-shaped through holes is set according to actual needs. The strip-shaped through holes can reduce the weight of the third protection board 103 and the fourth protection board 104, reduce the weight of the PCB components, and facilitate stress release, thereby improving the structural strength of the third protection board 103 and the fourth protection board 104.

[0066] Continue to refer to Figure 1 Optionally, the PCB plug-in also includes: a front panel 107, a first connection terminal 108 and a second connection terminal 109, the first connection terminal 108 and the second connection terminal 109 being electrically connected to the PCB board 105 respectively, and the front panel 107 and the first connection terminal 108 being located at two openings of the housing respectively.

[0067] The front panel 107 is fixedly connected to the first protective plate 101 and the second protective plate 102;

[0068] The front panel 107 has multiple openings, and the second connection terminal 109 is disposed in the opening. A puller 110 is disposed at one end of the front panel 107 adjacent to the third protection plate 103 and at one end of the front panel 107 adjacent to the fourth protection plate 104.

The front panel 107 is located at the front opening of the enclosure, the first connecting terminal 108 is located at the rear opening of the enclosure, and the second connecting terminal 109 is disposed in multiple openings of the front panel 107. The first connecting terminal 108 and the second connecting terminal 109 are electrically connected to the PCB board 105. The first connecting terminal 108 is used to connect to the PCB motherboard of the insertion box, and the second connecting terminal 109 is used to connect to external devices to achieve communication. The pull-out aid 110 can realize the initial locking and limiting function of PCB insertion, which is convenient and quick to operate, requires no tools, and has high reliability and strong adaptability.

[0070] Optionally, the circuit element 106 in the PCB assembly includes a transformer.
