Description

Technical Field

[0001] This application relates to the technical field of circuit board mounting brackets, and in particular to a double-headed bracket. Background Technology

[0002] A circuit board is made of an insulating substrate and an etched conductive copper layer. It is the core carrier used to mount electronic components and realize the electrical interconnection between components through wires. The core function of the circuit board is to provide physical support, conduct circuits, and transmit signals for electronic systems.

[0003] Parallel connection of two circuit boards can improve space utilization and facilitate heat dissipation during use. In applications involving high-density integration and modular functionality in electronic devices, it is often necessary to arrange circuit boards vertically and mount them on objects.

[0004] Two circuit boards are designated as the first circuit board and the second circuit board. First, the first circuit board is placed above the fixing tube of the object. Then, the first circuit board is fixed to the fixing tube by the first bolt. Next, multiple support sleeves are placed on the first circuit board, and the second circuit board is placed on the support sleeves. Finally, the second bolt passes through the second circuit board and the sleeves in sequence and is threaded onto the first circuit board.

[0005] The connection process between the first and second circuit boards requires multiple bolts and support sleeves, and tools are needed to tighten them, making the installation inconvenient. Utility Model Content

[0006] To improve the problem of inconvenient connection between the first and second circuit boards, this application provides a double-headed bracket.

[0007] This application provides a dual-head support, which adopts the following technical solution:

[0008] A double-headed bracket includes a spacing post, one end of which is provided with a first snap-fit ​​structure and the other end of which is provided with a second snap-fit ​​structure. The first snap-fit ​​structure is used to engage with a first circuit board, and the second snap-fit ​​structure is used to engage with a second circuit board.

[0009] By adopting the above technical solution, the first snap-fit ​​structure is inserted into the first circuit board, and the second snap-fit ​​structure is inserted into the second circuit board, thereby achieving relative fixation and maintaining a gap between the first circuit board and the second circuit board. The above connection method reduces the number of components such as bolts and support sleeves used to connect the first circuit board and the second circuit board, and does not require the use of tools such as screwdrivers, making the connection between the first circuit board and the second circuit board simpler and more convenient.

[0010] Optionally, the second snap-fit ​​structure includes a connecting post, a connecting head, and an elastic block. The connecting post is fixedly connected to the end of the spacing post away from the first snap-fit ​​structure, the connecting head is fixedly connected to the end of the connecting post away from the spacing post, and the elastic block is disposed on the side of the connecting head facing the spacing post.

[0011] By adopting the above technical solution, the connector guides the second snap-fit ​​structure to be inserted into the hole of the second circuit board, and the elastic block deforms to fix the second circuit board, thereby realizing the connection between the second circuit board and the second snap-fit ​​structure.

[0012] Optionally, a stop block is provided on the side of the connecting post, and a guide surface is provided on the stop block. The guide surface is located at the junction of the end face of the stop block facing the connector and the end of the stop block away from the connecting post.

[0013] By adopting the above technical solution, when the second buckle structure is connected to the second circuit board, the stop block abuts against the inner wall of the hole in the second circuit board, making it difficult for the double-headed bracket to move radially along the hole in the second circuit board; the guide surface facilitates the insertion of the stop block into the hole in the second circuit board.

[0014] Optionally, the elastic block has a snap-fit ​​groove on its surface away from the stop block, and the snap-fit ​​groove passes through the elastic block in a horizontal direction perpendicular to the axis of the snap-fit ​​groove.

[0015] By adopting the above technical solution, after the second snap-fit ​​structure is connected to the second circuit board, the inner wall of the snap-fit ​​groove away from the spacing post abuts against the end face of the second circuit board away from the spacing post, and the bottom wall of the snap-fit ​​groove abuts against the inner wall of the hole of the second circuit board, thereby increasing the stability of the connection between the second snap-fit ​​structure and the second circuit board.

[0016] Optionally, the second snap-fit ​​structure further includes a shielding plate, which is disposed on the side of the connecting post facing the elastic block, and the shielding plate is located on the side of the elastic block away from the connecting head.

[0017] By adopting the above technical solution, the shielding plate can cover the holes on the second circuit board, thereby achieving electrical isolation and reducing the probability of mutual interference between the first and second circuit boards.

[0018] Optionally, the distance from the shielding plate to the axis of the spacing column gradually increases in the direction away from the spacing column.

[0019] By adopting the above technical solution, during the process of installing the second circuit board into the inner wall of the snap-fit ​​slot near the connector and the shielding plate, the shielding plate is deformed, and the force of the shielding plate resetting is applied to the second circuit board, thereby improving the firmness of the connection between the second snap-fit ​​structure and the shielding plate.

[0020] Optionally, the first snap-fit ​​structure includes a plug and a snap claw, wherein the plug has a snap claw on its side parallel to the axis of the spacing column, and the snap claw is elastic.

[0021] By adopting the above technical solution, when the first snap-fit ​​structure is inserted into the hole of the first circuit board, the snap claw is deformed by pressure. When the first circuit board abuts against the spacing post, the snap claw is reset, so that the snap claw abuts against the end face of the first circuit board away from the spacing post, thereby connecting the first snap-fit ​​structure with the first circuit board.

[0022] Optionally, the insert rod has a receiving hole on the side facing the buckle, and a plug is provided on the inner wall of the receiving hole away from the spacing post, with one side of the plug being fixedly connected to the buckle.

[0023] By adopting the above technical solution, the opening of the receiving hole makes the insertion rod easier to deform; the insertion block can improve the strength between the latch and the insertion rod.

[0024] Optionally, the end of the latch facing the spacing post is provided with a locking block.

[0025] By adopting the above technical solution, when the first buckle structure is connected to the first circuit board, the insert rod abuts against the inner wall of the hole, and then abuts against the inner wall of the hole of the first circuit board with the help of the buckle block, making it less likely for the double-headed bracket to move radially along the hole of the first circuit board, thereby improving the stability of the double-headed bracket and the first circuit board.

[0026] Optionally, an annular groove is formed on the outer surface of the spacing column.

[0027] By adopting the above technical solution, the setting of the annular groove helps to pass the wire and fix the wire.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The first snap-fit ​​structure is inserted into the hole on the first circuit board, and the second snap-fit ​​structure is inserted into the hole on the second circuit board, thereby achieving relative fixation between the first circuit board and the second circuit board, which can reduce the number of bolts used and make the connection simpler and more convenient;

[0030] 2. The ring groove helps with wire routing and wire fixing. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0037] This embodiment discloses a dual-head bracket. (Refer to...) Figure 1 and Figure 2 The double-headed bracket is used to connect the first circuit board and the second circuit board, so that the two are fixed relative to each other and kept apart.

[0038] Reference Figure 1 A double-headed bracket includes a first snap-fit ​​structure 1, a second snap-fit ​​structure 2, and a spacing column 3. The spacing column 3 is columnar, and an annular groove 31 is formed on the outer circumferential surface of the spacing column 3.

[0039] Reference Figure 2 The first snap-fit ​​structure 1 is used to engage with the first circuit board, and is located at one end of the spacing post 3. The first snap-fit ​​structure 1 includes a plug rod 11 and a snap claw 12.

[0040] Reference Figure 1 The insertion rod 11 is fixedly connected to the end face of the spacing column 3. The insertion rod 11 includes two parallel fixing surfaces. The fixing surfaces are parallel to the axis of the spacing column 3. A receiving hole 111 is provided on the fixing surfaces.

[0041] Reference Figure 1 and Figure 2The latch 12 is fixedly connected to the fixed surface, and the connection point between the latch 12 and the insert rod 11 is located on the side of the receiving hole 111 away from the spacing post 3. The latch 12 has a triangular cross-section, and the distance between the inclined surface of the latch 12 and the insert rod 11 gradually increases along the direction closer to the spacing post 3. The inclined surface of the latch 12 has a guiding function. The latch 12 is elastic. An insert block 1111 is fixedly connected to the side of the latch 12 facing the receiving hole 111, and the insert block 1111 is inserted into the receiving hole 111. The side of the insert block 1111 away from the spacing post 3 is fixedly connected to the inner wall of the receiving hole 111. A locking block 121 is provided at the end of the latch 12 near the spacing post 3. The locking block 121 extends into the receiving hole 111 and is fixedly connected to the insert block 1111. When the first latch structure 1 is connected to the hole of the first circuit board, one end of the first circuit board abuts against the latch 12, and the other end abuts against the spacing post 3.

[0042] Reference Figure 1 and Figure 3 The second snap-fit ​​structure 2 includes a shielding plate 25, a connecting post 21, a stop block 22, a connector 23, and an elastic block 24. The end of the connecting post 21 closest to the first snap-fit ​​structure 1 is fixedly connected to the spacing post 3. The end of the connecting post 21 furthest from the first snap-fit ​​structure 1 is fixedly connected to the connector 23.

[0043] Reference Figure 3 The side of the connector 23 away from the stop block 22 is arc-shaped, guiding the second snap-fit ​​structure 2 into the hole of the second circuit board.

[0044] Reference Figure 1 and Figure 2 Two elastic blocks 24 are provided, symmetrically distributed about the central axis of the connecting post 21. Both elastic blocks 24 are fixedly connected to the end of the connector 23 near the connecting post 21. The distance from the elastic block 24 to the axis of the connecting post 21 gradually increases towards the connecting post 21. Each of the two elastic blocks 24 has a locking groove 241 on its surface away from the stop block 22. The locking groove 241 penetrates the elastic block 24 along the axis of the receiving hole 111 and extends towards the spacing post 3.

[0045] Reference Figure 1 and Figure 3 Two shielding plates 25 are provided, and the two shielding plates 25 are distributed circumferentially along the side surface of the connecting column 21. Both shielding plates 25 are fixedly connected to the side of the connecting column 21 facing the elastic block 24. Both shielding plates 25 are located on the side of the elastic block 24 away from the connector 23. The shielding plates 25 are bent away from the spacing column 3.

[0046] Reference Figure 1 and Figure 3Two stop blocks 22 are provided. One stop block 22 is connected to one end of the connecting post 21 along the axis of the receiving hole 111, and the other stop block 22 is connected to the other end of the connecting post 21 along the axis of the receiving hole 111. A guide surface is provided on the stop block 22, which is located at the junction of the end face of the stop block 22 facing the connector 23 and the end of the stop block 22 away from the connecting post 21.

[0047] The implementation principle of a double-headed bracket in this application embodiment is as follows: when the first buckle structure 1 is inserted into the hole of the first circuit board, the buckle claw 12 is deformed by pressure. After the first circuit board abuts against the spacing post 3, the buckle claw 12 passes through the hole of the first circuit board and resets, so that the buckle claw 12 abuts against the end face of the first circuit board away from the spacing post 3, so that the double-headed bracket is connected to the first circuit board.

[0048] When the second snap-fit ​​structure 2 is inserted into the hole of the second circuit board, the connector 23 and the elastic block 24 first enter the hole of the second circuit board. The surface of the elastic block 24 away from the connecting post 21 is against the inner wall of the hole of the second circuit board. As the second snap-fit ​​structure 2 moves further, the elastic block 24 deforms. When the surface of the elastic block 24 away from the connecting post 21 no longer abuts against the inner wall of the hole of the second circuit board, the elastic block 24 resets, so that the end face of the second circuit board away from the spacing post 3 abuts against the inner wall of the snap-fit ​​groove 241 away from the spacing post 3, the end face of the second circuit board near the spacing post 3 abuts against the shielding plate 25, and the inner wall of the hole of the second circuit board abuts against the bottom wall of the snap-fit ​​groove 241, thereby realizing the connection between the double-headed bracket and the first circuit board.
