Description

Technical Field

[0001] The present application relates to the field of PCBA board installation structures, and in particular to a PCBA board vertical installation structure. Background Art

[0002] PCBA board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a provider of circuit connections for electronic components. Because it is made using electronic printing technology, it is called a "printed" circuit board. Before the emergence of printed circuit boards, the interconnection between electronic components was directly connected by wires to form a complete circuit.

[0003] Most of the existing PCBA boards adopt a horizontal installation structure and are locked in the housing by screws. The screws for locking the PCB board are relatively small. When the smaller screws are turned, the screw slots on the screw heads of the screws are easily worn, which brings great inconvenience to the disassembly and assembly of the PCB board. Moreover, after the PCBA board is locked, one side is close to the inner wall of the housing, and the area of ​​the inner wall of the housing occupied is relatively large, which is not conducive to the compact layout of the interior of the housing, and is not conducive to the development of lightweight products. Utility Model Content

[0004] In order to optimize the installation structure of the PCBA board and effectively improve the layout inside the product housing, the present application provides a vertical installation structure of the PCBA board.

[0005] The present application provides a PCBA board vertical installation structure, which adopts the following technical solutions:

[0006] A PCBA board vertical installation structure, comprising:

[0007] A housing, wherein a mounting groove is provided in the housing, and the mounting groove is vertically arranged;

[0008] A plurality of ribs are arranged on the inner side wall of the installation groove, and the inner sides of all the ribs are enclosed to form an accommodating space;

[0009] A PCBA board body is arranged in close contact with the inner wall of the accommodating space;

[0010] The upper end of the rib is provided with a guiding inclined surface, and the guiding inclined surface is inclined downward from an end away from the accommodating space to an end close to the accommodating space.

[0011] By adopting the above technical solution, when installing the PCBA board body, it is only necessary to insert the PCBA board body into the accommodating space to realize the insertion of the PCBA board body, which is convenient for installation. At the same time, due to the adoption of a vertical installation structure, the plane occupied area of ​​the inner wall of the shell is reduced, which is conducive to the compact layout of the shell interior and the lightweight development of the product. The PCBA board body is separated from the groove wall of the installation groove by ribs, which increases the heat dissipation space of the PCBA board body and improves the heat dissipation effect of the PCBA board body. In addition, when inserting the PCBA board body, the PCBA board body is guided by the guide bevel, which facilitates the insertion of the PCBA board body into the accommodating space and improves the installation efficiency of the PCBA board body.

[0012] Optionally, a plurality of bottom ribs are arranged at intervals on the bottom wall of the mounting groove.

[0013] By adopting the above technical solution, the PCBA board body is separated from the bottom wall of the installation groove by the bottom rib, which reduces heat accumulation and further improves the heat dissipation performance of the installation structure.

[0014] Optionally, a limiting column is provided on the shell, and a limiting block is movably provided on the limiting column, and the bottom end of the limiting block abuts against the top surface of the PCBA board body.

[0015] By adopting the above technical solution, after the PCBA board body is inserted into the accommodating space, the PCBA board body is further limited by the limit block, thereby reducing the possibility of the PCBA board body escaping from the accommodating space from above or generating vertical jump, and further ensuring the installation strength of the PCBA board body.

[0016] Optionally, the limiting column is located on the upper side of one end of the mounting groove, and the side wall of the limiting column abuts against the end wall of the PCBA board body.

[0017] By adopting the above technical solution, when the PCBA board body is inserted, the end wall of the PCBA board body is placed close to the limiting column to facilitate the positioning of the PCBA board body; at the same time, the limiting column can further support the end of the PCBA board body, thereby improving the stability and reliability of the installation of the PCBA board body.

[0018] Optionally, a limiting groove is provided on one side of the limiting column close to the PCBA board body, and an elastic member is provided in the limiting groove, one end of the elastic member is connected to the bottom wall of the limiting groove, and the other end is connected to the limiting block; when the elastic member is in a natural state, the limiting block is partially located in the limiting groove; when the elastic member is at the compression limit, the limiting block is completely located in the limiting groove.

[0019] By adopting the above technical solution, when installing the PCBA board body, the limit block is pressed so that the limit block is retracted into the limit groove, and the elastic member is compressed at the same time, so that the PCBA board body is vertically inserted into the accommodating space; when the PCBA board body is inserted into place, the limit block is released, the elastic member is reset, the limit block is popped out of the limit groove, and the limit block is against the upper end of the PCBA board body, so as to limit the PCBA board body in the vertical direction.

[0020] Optionally, a guide arc surface is provided at the upper end of the limit block and on one side close to the PCBA board body, and the guide arc surface gradually slopes downward from an end away from the PCBA board body to an end close to the PCBA board body, and when the elastic member is in a natural state, the lower end of the guide inclined surface is located in the limit groove or coincides with the opening edge of the limit groove.

[0021] By adopting the above technical solution, when installing the PCBA board body, there is no need to press the limit block separately. Through the setting of the guide arc surface, the PCBA board body is pressed downward to cause the limit block to automatically retract into the limit groove, thereby further improving the installation efficiency.

[0022] Optionally, a pull rod is provided at one end of the limit block away from the PCBA board body, and the pull rod passes through the elastic member and passes out of the limit column, and the limit column is provided with a through hole for the pull rod to pass through.

[0023] By adopting the above technical solution, when the PCBA board body needs to be repaired or replaced, the limit block can be pulled into the limit groove by pulling the pull rod, so as to facilitate the disassembly of the PCBA board body.

[0024] Optionally, a connecting base is provided at the bottom of the limiting column, a bonding surface is provided at the bottom end of the connecting base, and the connecting base is bonded to the shell through the bonding surface.

[0025] By adopting the above technical solution, the contact area between the limiting column and the shell is increased by connecting the base, thereby increasing the area of ​​the bonding surface, which is beneficial to improving the bonding strength between the limiting column and the shell and reducing the possibility of the limiting column falling off.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Through the setting of the accommodating space, when installing the PCBA board body, you only need to insert the PCBA board body into the accommodating space to realize the insertion of the PCBA board body, which is convenient for installation. At the same time, due to the adoption of a vertical installation structure, the plane occupied area of ​​the inner wall of the shell is reduced, which is conducive to the compact layout of the shell interior and the lightweight development of the product. The PCBA board body is separated from the groove wall of the installation groove by ribs, which increases the heat dissipation space of the PCBA board body and improves the heat dissipation effect of the PCBA board body. In addition, when inserting the PCBA board body, the PCBA board body is guided by the guide bevel, which facilitates the insertion of the PCBA board body into the accommodating space and improves the installation efficiency of the PCBA board body.

[0028] 2. By setting the bottom ribs, the PCBA board body is separated from the bottom wall of the installation groove by the bottom ribs, which reduces heat accumulation and further improves the heat dissipation performance of the installation structure.

[0036] The following is combined with Figure 1-5 , further details of this application are given.

[0037] Embodiment 1:

[0038] The first embodiment of the present application discloses a PCBA board vertical installation structure. Figure 1-2 A PCBA board vertical installation structure includes a shell 1 and a PCBA board body 2. A mounting groove 3 is provided in the shell 1. The mounting groove 3 is vertically arranged. A plurality of ribs 4 are integrally formed on the inner side wall of the mounting groove 3. The inner sides of all the ribs 4 enclose a receiving space 5 for receiving the PCBA board body 2. The PCBA board body 2 is fitted on the inner side wall of the receiving space 5.

[0039] When installing the PCBA body 2, the PCBA body 2 can be installed by simply inserting it into the accommodating space 5, which is convenient for installation. At the same time, due to the vertical installation structure, the plane occupied area of ​​the inner wall of the housing 1 is reduced, which is conducive to the compact layout of the interior of the housing 1 and the lightweight development of the product. The PCBA body 2 is separated from the groove wall of the installation groove 3 by the ribs 4, which increases the heat dissipation space of the PCBA body 2 and improves the heat dissipation effect of the PCBA body 2.

[0040] Reference Figure 2 The upper end of the rib 4 is provided with a guide slope 41, which is inclined downward from the end away from the accommodating space 5 to the end close to the accommodating space 5. When the PCBA board body 2 is inserted, the guide slope 41 guides the PCBA board body 2, which facilitates the insertion of the PCBA board body 2 into the accommodating space 5, thereby improving the installation efficiency of the PCBA board body 2.

[0041] Reference Figure 2 The bottom wall of the mounting groove 3 is integrally formed with a plurality of bottom ribs 31 arranged at intervals. Thus, the bottom ribs 31 are used to separate the PCBA board body 2 from the bottom wall of the mounting groove 3, thereby reducing heat accumulation and further improving the heat dissipation performance of the mounting structure.

[0042] Embodiment 2:

[0043] The second embodiment of the present application discloses a PCBA board vertical installation structure. Figure 3-4 The difference between the second embodiment and the first embodiment is that: a limiting column 6 is fixed on the inner wall of the housing 1, and a limiting block 7 is movably provided on the limiting column 6, and the bottom end of the limiting block 7 abuts against the top surface of the PCBA board body 2. After the PCBA board body 2 is inserted into the accommodating space 5, the limiting block 7 further limits the PCBA board body 2, reducing the possibility of the PCBA board body 2 escaping from the accommodating space 5 from above or generating vertical jumps, and further ensuring the installation strength of the PCBA board body 2.

[0044] Reference Figure 4The bottom of the limiting column 6 is integrally formed with a connecting base 8, and the bottom end of the connecting base 8 is provided with a bonding surface 81, and the connecting base 8 is bonded to the inner wall of the housing 1 through the bonding surface 81. The contact area between the limiting column 6 and the housing 1 is increased by connecting the base 8, and the area of ​​the bonding surface 81 is further increased, which is conducive to improving the bonding strength between the limiting column 6 and the housing 1 and reducing the possibility of the limiting column 6 falling off.

[0045] Reference Figure 3 The limiting column 6 is located on the upper side of one end of the installation groove 3, and the side wall of the limiting column 6 abuts against the end wall of the PCBA board body 2. When inserting the PCBA board body 2, the end wall of the PCBA board body 2 is closely attached to the limiting column 6, which can facilitate the positioning of the PCBA board body 2; at the same time, the limiting column 6 can further support the end of the PCBA board body 2, thereby improving the stability and reliability of the installation of the PCBA board body 2.

[0046] Reference Figure 3-5 , a limiting groove 61 is provided on one side of the limiting column 6 close to the PCBA board body 2, an elastic member 62 is installed in the limiting groove 61, and one end of the elastic member 62 is fixed to the bottom wall of the limiting groove 61, and the other end is fixed to the limiting block 7; when the elastic member 62 is in a natural state, the limiting block 7 is partially located in the limiting groove 61; when the elastic member 62 is at the compression limit, the limiting block 7 is completely located in the limiting groove 61. In the second embodiment, the elastic member 62 is a compression spring. When the PCBA board body 2 is installed, the limiting block 7 is pressed so that the limiting block 7 is retracted into the limiting groove 61, and the elastic member 62 is compressed, so that the PCBA board body 2 is vertically inserted into the accommodating space 5; when the PCBA board body 2 is inserted into place, the limiting block 7 is released, the elastic member 62 is reset, and the limiting block 7 is ejected from the limiting groove 61, and the limiting block 7 is against the upper end of the PCBA board body 2 to achieve the limitation of the PCBA board body 2 in the vertical direction.

[0047] Reference Figure 3-5 A guide arc surface 71 is provided at the upper end of the limit block 7 and on the side close to the PCBA board body 2. The guide arc surface 71 gradually slopes downward from the end away from the PCBA board body 2 to the end close to the PCBA board body 2, and when the elastic member 62 is in a natural state, the lower end of the guide slope 41 is located in the limit groove 61 or coincides with the opening edge of the limit groove 61. When installing the PCBA board body 2, there is no need to press the limit block 7 separately. Through the setting of the guide arc surface 71, the PCBA board body 2 is pressed downward to cause the limit block 7 to automatically retract into the limit groove 61, further improving the installation efficiency.

[0048] Reference Figure 3-5The end of the limit block 7 away from the PCBA board body 2 is fixedly connected with a pull rod 9, which passes through the elastic member 62 and passes through the limit column 6. The limit column 6 is provided with a through hole 63 for the pull rod 9 to pass through. One end of the through hole 63 is connected to the limit groove 61, and the other end is connected to the outside of the limit column 6.
