Description

Technical Field

[0001] This utility model is a deformation-resistant circuit board, belonging to the field of circuit boards. Background Technology

[0002] A circuit board is a basic electronic component used for mounting electronic components and connecting circuits. It consists of a circuit board formed by covering a conductive material with an insulating material. If the circuit board is not flat, it will cause inaccurate positioning, and the components cannot be inserted or mounted onto the holes and surface mount pads of the board. If the circuit board with the components mounted is bent after soldering, it is difficult to trim the component leads neatly, and the board cannot be mounted into the chassis or internal socket. Therefore, encountering a warped board is also very troublesome. Current surface mount technology is developing towards high precision, high speed, and intelligence, which puts forward higher requirements for the flatness of the circuit board, which is the home of various components.

[0003] In the prior art, in order to prevent the circuit board from being damaged by external forces, a fixing frame is used to protect the circuit board. Since electronic components are usually arranged on the surface of the circuit board, and the position of the electronic components on the surface of the circuit board is arranged according to needs, when the electronic components are arranged at the edge of the circuit board, the fixing frame will come into contact with the electronic components located at the edge of the circuit board during assembly, so that the position of the electronic components hinders the assembly of the fixing frame and the circuit board. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a deformation-resistant circuit board to solve the problems mentioned in the background art. This utility model can make the fixing frame adjust the position of the fixing circuit board according to the position of the electronic components on the circuit board, so that the electronic components will not affect the placement of the fixing frame.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a deformation-resistant circuit board, comprising a circuit board, wherein a horizontal plate is movably connected to the surface of the circuit board, and a locking block is slidably connected to the surface of the horizontal plate;

[0006] The card block has a card sleeve fixedly arranged inside, and a nut is fixedly connected inside the card sleeve. A threaded rod is threadedly connected to the center of the nut. A connecting plate is fixedly connected to the surface of the card sleeve. A long plate is slidably connected to the top center of the card block. A first locking bolt is threadedly connected to the surface of the long plate. A pad is fixedly installed at the bottom end of the long plate. A bolt is threadedly connected to the center of the pad.

[0007] Furthermore, one card block is arranged on each of the two sides of each top corner of the circuit board. A sliding groove is provided at the position where the card block contacts the horizontal plate. Two sleeves and nuts are symmetrically arranged on the top surface of each card block. The threaded rod passes through the sleeves, nuts and circuit board at two corresponding positions at the same time.

[0008] Furthermore, the top center of the card block has a first groove that matches the shape of the long plate, the first latch passes through the long plate and connects to the card block, the bottom of the pad contacts the surface of the circuit board, and the bolt passes through the pad and connects to the circuit board.

[0009] Furthermore, a side plate is fixedly installed on the side of the card block, a second latch is threadedly connected to the surface of the side plate, an auxiliary rod is movably arranged inside the side plate, a bottom rod is fixedly connected to the bottom surface of the card block at the bottom of the circuit board, and a bottom block is fixedly connected to the bottom end of the bottom rod.

[0010] Furthermore, two side plates are arranged on the side of the card block. The two side plates are located on the same side of the card block corresponding to the positions on both sides of the circuit board. The two side plates are connected to the two card blocks at the same time. A second groove is provided at the position where the card block and the side plate contact the auxiliary rod.

[0011] Furthermore, two second latches are symmetrically arranged on the surface of each side plate, and the two second latches simultaneously pass through the side plate and the auxiliary rod and contact a locking block respectively.

[0012] The beneficial effects of this utility model are as follows: First, the clips need to be fixed on both sides of each corner of the circuit board. The threaded rod is passed through the two corresponding nuts to fix the clips. At the same time, the clips are brought into contact with the horizontal plate, and the long plate is on the top surface of the clips. Then, the long plate is pulled to move the pad next to the electronic component. Then, the bolt is passed through the pad, and the first latch fixes the position of the moved long plate. Under the action of the long plate and the clip, the edge of the circuit board where the electronic component is located will not affect the protection of the circuit board, and the electronic component will not affect the placement of the fixing frame.

[0013] Next, install the side plate on the side of the card block, and then place the auxiliary rod in the second groove at the contact position between the side plate and the card block. At the same time, use the second latch to pass through the side plate to fix the auxiliary rod. Then, stack different cards on top of the card block. The auxiliary rod passes through the connection between two different cards and the side plate, so that different cards can be stacked through the position of the auxiliary rod, thereby achieving the stacking of the fixing frame for protecting the circuit board, so as to reduce the space occupied by multiple fixing frames.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a deformation-resistant circuit board, including a circuit board 1, a horizontal plate 2 movably connected to the surface of the circuit board 1, and a locking block 3 slidably connected to the surface of the horizontal plate 2; one locking block 3 is arranged on each side of each top corner of the circuit board 1, and a sliding groove is formed at the position where the locking block 3 contacts the horizontal plate 2; two sleeves 4 and nuts 401 are symmetrically arranged on the top surface of each locking block 3, and a threaded rod 402 passes through the sleeves 4, nuts 401, and circuit board 1 at two corresponding positions. A first groove matching the shape of a long plate 5 is formed at the top center of the locking block 3, and a first bolt 501 passes through the long plate 5 and connects to the locking block 3; the bottom of a pad 502 contacts the surface of the circuit board 1, and a bolt 503 passes through the pad 502 and connects to the circuit board 1.

[0022] The internal part of the clamping block 3 is fixedly arranged with a clamping sleeve 4. The internal part of the clamping sleeve 4 is fixedly connected with a nut 401. The center of the nut 401 is threadedly connected with a threaded rod 402. The surface of the clamping sleeve 4 is fixedly connected with a connecting plate 403. The top center of the clamping block 3 is slidably connected with a long plate 5. The surface of the long plate 5 is threadedly connected with a first clamping bolt 501. The bottom end of the long plate 5 is fixedly installed with a pad 502. The center of the pad 502 is threadedly connected with a bolt 503.

[0023] Please see Figures 1 to 3A side plate 6 is fixedly installed on the side of the card block 3. A second latch 601 is threadedly connected to the surface of the side plate 6. An auxiliary rod 7 is movably arranged inside the side plate 6. A bottom rod 8 is fixedly connected to the bottom surface of the card block 3 at the bottom of the circuit board 1. A bottom block 801 is fixedly connected to the bottom end of the bottom rod 8.

[0024] Two side plates 6 are arranged on the side of the locking block 3. The two side plates 6 are located on the same side of the locking block 3 corresponding to the positions on both sides of the circuit board 1. The two side plates 6 connect to the two locking blocks 3 at the same time. A second groove is provided at the position where the locking block 3 and the side plate 6 contact the auxiliary rod 7.

[0025] Detailed implementation: First, when it is necessary to adjust the position of the fixed circuit board 1 according to the position of the electronic components on the circuit board 1, the clip 3 needs to be fixed on both sides of each top corner of the circuit board 1. At the same time, the threaded rod 402 is used to pass through the nut 401 on the surface of the clip 3 at the two corresponding positions, so that the clip 3 is fixed on the surface of the circuit board 1.

At this time, the long plate 5 can be pulled according to the position of the electronic components on the surface of the circuit board 1, so that the long plate 5 moves the position of the pad 502 to the side of the electronic components. Then, the bolt 503 is used to pass through the position of the pad 502, and the first clamp 501 is used to fix the position of the moved long plate 5. Under the action of the long plate 5 and the clip 4, the edge position of the circuit board 1 where the electronic components are located will not affect the protection of the circuit board 1, and the electronic components will not affect the placement of the fixed frame.

At the same time, the second latch 601 is used to pass through the side plate 6 to fix the position of the auxiliary rod 7. Then, different card blocks 3 are stacked on top of the card block 3, so that the auxiliary rod 7 passes through the connection between the two different card blocks 3 and the side plate 6, so that different card blocks 3 can be stacked through the position of the auxiliary rod 7, thereby stacking the fixed frames of the circuit board 1 to reduce the space occupied by multiple fixed frames.
