Technical Field
[0001] The utility model relates to the technical field of installation and fixing of circuit boards, in particular to a tooling structure for locking circuit boards. Background Art
[0002] Circuit boards can be called printed circuit boards or printed circuit boards. They are composed of integrated circuits, quartz oscillators, fine-tuning capacitors and printed circuit boards. They are mainly used to connect various electronic components in electronic equipment and play the role of structural support. In the active contemporary electronic component industry, the use of them is growing rapidly.
[0003] The use of circuit boards requires the installation and fixation of the circuit boards, that is, the locking and limiting of the circuit boards. However, the components and connection methods of the circuit boards require the technical support of locking and limiting to reduce the probability of damage to the circuit boards. In this way, in the limiting structure of the circuit board, it is necessary to make corresponding structures for the possible interference of the circuit board, such as moisture-proof, drop-proof or collision-proof. At the same time, the limiting structure of the circuit board also needs to be designed to deal with the problems that arise in the limiting work of the circuit board, such as damage caused by contact between the limiting structure and the circuit board, the inability of the limiting structure to limit the installation of limiting boards of various widths, and the influence of the limiting structure on the circuit connection of the circuit board.
[0004] Chinese Patent Authorization Announcement No.: CN210432266U, authorization announcement date April 28, 2020, discloses a circuit board locking mechanism, including a heat dissipation component and a locking box, the heat dissipation component includes a heat dissipation plate and heat dissipation fins, and the heat dissipation fins are neatly and evenly placed on the heat dissipation plate; the heat dissipation plate on the heat dissipation component is fixedly installed on the locking box as a base, and the locking box includes a box frame, a sealing edge and an elastic support pad on all sides, and a heat dissipation component is installed on one side of the box frame to form a rectangular storage bin body; the box frame includes two parallel long axis frames and two parallel short axis frames, and the two short axis frames are respectively at the ends of the two parallel long axis frames and are perpendicular to the long axis frames, and together form a storage bin body; the long axis frame and the short axis frame are both L-shaped structures and the L-shaped structure The bottom surface extends outward to form a pressure pad mounting portion, and the long axis frame on one side and the short axis frame on one side are connected by a clamping connector; a locking assembly is also provided between the two long axis frames, and the locking assembly includes an upper locking member, a middle locking member, a lower locking member and a locking rod, the upper locking member and the middle locking member are fixedly mounted on the outside of the short axis frame, and the lower locking member is mounted on the long axis frame, and the locking rod passes through the upper locking member, the middle locking member and the lower locking member; the upper locking member and the lower locking member have the same structure, both of which are composed of a nut and a right-angled trapezoidal structure, and a hole and an internal thread matching the screw rod are provided on the inclined surface of the right-angled trapezoid; an elastic rubber pad is installed on the pressure pad mounting portion, and the elastic support pad is fixedly mounted on the elastic rubber pad, a circuit board is fixed on the elastic support pad, and the sealing edge of the circuit board is fixed without damage by the elastic rubber pad. The shortcoming of this technical solution is that the circuit board is fixedly mounted on the elastic support pad. In other words, one circuit board locking mechanism can only install one circuit board and can only lock and limit one circuit board. Therefore, the circuit board cannot be replaced smoothly, which reduces the scope of use of the circuit board locking mechanism.
[0005] In summary, a device can be provided to allow circuit boards of various widths to be locked and limited, which is convenient for replacing circuit boards that need to be locked and limited. Utility Model Content
[0006] The utility model aims to overcome the disadvantage of the prior art that it is inconvenient to replace a circuit board for locking and limiting, and provides a tooling structure for locking the circuit board which is convenient for smoothly performing the locking, installation and disassembly work of the circuit board.
[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0008] A tooling structure for locking a circuit board comprises a locking box and a circuit board, wherein the locking box is provided with a locking groove, wherein the locking groove comprises a notch and a groove bottom, wherein the notch is arranged at the top end of the locking box, and the groove bottom is arranged at the bottom end of the locking box, wherein a slot is arranged at the locking groove, wherein the slot comprises a slot opening and a slot bottom, wherein the slot opening is communicated with the locking groove, wherein a limit block is installed in the slot, wherein the limit block is detachably connected to the locking box, wherein the circuit board is inserted into the locking groove through the notch, wherein the outer edge of the circuit board is detachably connected to the front end of the limit block, wherein an elastic pad is installed at the rear end of the limit block, wherein the elastic pad is arranged at the bottom of the slot, and wherein the elastic pad is connected to the locking box.
[0009] This design allows the circuit board to be inserted through the locking slot on the locking box. The locking slot includes a slot opening and a slot bottom. The slot opening is placed at the top of the locking box, and the slot bottom is placed at the bottom of the locking box. Then, the bottom of the circuit board can be inserted through the slot at the top of the locking box until the bottom of the circuit board is placed at the slot bottom at the bottom of the locking box and is limited by the slot bottom. Of course, the top of the circuit board is also placed next to the slot, so the circuit board is initially limited. If there is a slot on the locking slot, the slot includes a slot opening and a slot bottom. The slot opening is connected to the locking slot. Then, when inserting the circuit board, the outer edge of the circuit board can be placed at the slot opening and move up and down under the limiting effect of the slot. The limit block is installed in the slot, and the outer edge of the circuit board is detachably connected to the front end of the limit block, that is, the insertion of the circuit board is carried out under the contact with the limit block. In other words, the movement of the circuit board is carried out in contact with the limit block, so the movement of the circuit board generates friction with the limit block, and an elastic pad is installed at the rear end of the limit block, which is placed at the bottom of the slot and connected to the locking box. This not only avoids the movement of the circuit board and the friction with the elastic pad or the locking box, thereby preventing the elastic pad or the locking box from being damaged by friction, so as to ensure the long-term use of the locking box, but also can give play to the elastic effect of the elastic pad, so that the limit block is affected by the extrusion when the circuit board moves, and automatically moves the limit block to meet the width requirement of the circuit board, so that the locking and limiting work of the circuit board can be successfully completed, and the limit block and the elastic pad installed in the slot at the locking groove achieve the purpose of facilitating the smooth locking, installation and removal of the circuit board.
[0010] Preferably, there are two slots, which are symmetrically distributed at the left and right ends of the locking slot. A limiting strip is installed on the locking box, and the limiting strip is matched with the top end of the locking box, and the limiting strip is detachably connected to the locking box. With this design, by symmetrically distributing the two slots at the left and right ends of the locking slot, when the circuit board is inserted into the locking slot, the left and right ends of the circuit board can be smoothly placed in the slots, so as to receive the working support of the limiting blocks and elastic pads in the slots, that is, the movement of the circuit board can be avoided, and the elastic pads or the locking box can be prevented from being damaged by friction. Moreover, it can be adjusted for circuit boards of various widths, so as to facilitate the installation and disassembly and cleaning of various circuit boards. And a limiting strip is installed on the locking box, the limiting strip is matched with the top end of the locking box, and the limiting strip is detachably connected to the locking box. Finally, the limiting strip can be installed at the top end position of the locking box to block the slot opening of the locking slot, so as to prevent the circuit board from detaching from the locking box through the slot opening.
[0011] Preferably, the structure of the limiting block is in a U shape, and the outer edge of the circuit board is matched with the U-shaped limiting block. With this design, by making the structure of the limiting block in a U shape and the outer edge of the circuit board being matched with the U-shaped limiting block, the contact length between the limiting block and the outer edge of the circuit board is increased, so as to prevent the circuit board from moving and contacting the locking box, and causing friction damage to the locking box.
[0012] Preferably, two blocking strips are installed at the slot opening, and the two blocking strips are symmetrically distributed at the left and right ends of the slot. The width value of the slot opening is greater than the spacing value between the two blocking strips. With this design, by installing two blocking strips at the slot opening and making the two blocking strips symmetrically distributed at the left and right ends of the slot, and the width value of the slot opening here is greater than the spacing value between the two blocking strips, that is, the inserted circuit board is limited by the blocking strips, so as to prevent the circuit board from detaching from the slot during movement.
[0013] Preferably, the front end of the locking groove is open, a limiting thin plate is installed at the rear end of the locking groove, the front end of the limiting thin plate is detachably connected to the locking box, a heat sink is installed at the rear end of the limiting thin plate, the heat sink is connected to the limiting thin plate, a plurality of heat dissipation strips are installed on the heat sink, the plurality of heat dissipation strips are evenly distributed, a plurality of heat dissipation holes are arranged on the heat sink, and the heat dissipation holes are evenly distributed between adjacent heat dissipation strips. This design sets the front end of the locking groove as an open shape, and installs the limiting thin plate at the rear end, so that after the circuit board is inserted, the front end of the circuit board is displayed at the front end of the locking groove, which is convenient for checking and repairing the circuit board. The limiting plate further limits the circuit board. The detachable connection method adopted between the front end of the limiting plate and the locking box facilitates the installation and disassembly of the limiting plate. A heat sink is installed at the rear end of the limiting plate, and the heat sink is connected to the limiting plate. A number of heat sinks are installed on the heat sink, and the heat sinks are evenly distributed, and the heat dissipation holes are evenly distributed between adjacent heat sinks. Therefore, the heat around the circuit board can be dissipated not only through the front end of the locking groove, but also through the heat sinks and heat holes, so as to maintain the circuit board and allow the circuit board to be used for a long time.

A locking groove 5 is provided on the locking box 1. The locking groove 5 comprises a notch and a groove bottom. The notch is disposed at the top of the locking box 1, and the groove bottom is disposed at the bottom of the locking box 1. A slot 8 is provided at the locking groove 5. The slot 8 comprises a slot opening and a slot bottom. The slot opening is communicated with the locking groove 5. A limit block 11 is installed in the slot 8. The limit block 11 is detachably connected to the locking box 1. The circuit board 4 is inserted into the locking groove 5 through the notch. The outer edge of the circuit board 4 is detachably connected to the front end of the limit block 11. An elastic pad 10 is installed at the rear end of the limit block 11. The elastic pad 10 is disposed at the bottom of the slot. The elastic pad 10 is connected to the locking box 1.
[0023] like Figure 1 , Figure 3 and Figure 4As shown in the figure, the slot 8 contains two slots, and the two slots 8 are symmetrically distributed at the left and right ends of the locking slot 5. A limiting strip 12 is installed on the locking box 1. The limiting strip 12 matches the top end of the locking box 1, and the limiting strip 12 is detachably connected to the locking box 1. The structure of the limiting block 11 is in a U shape, and the outer edge of the circuit board 4 matches the U-shaped limiting block 11. Two blocking strips 9 are installed at the slot opening. The two blocking strips 9 are symmetrically distributed at the left and right ends of the slot 8. The width value of the slot opening is greater than the spacing value of the two blocking strips 9. The front end of the locking slot 5 is open. A limiting thin plate 2 is installed at the rear end of the locking slot 5. The front end of the limiting thin plate 2 is detachably connected to the locking box 1. A heat dissipation plate 3 is installed at the rear end of the limiting thin plate 2. The heat dissipation plate 3 is connected to the limiting thin plate 2. A plurality of heat dissipation strips 6 are installed on the heat dissipation plate 3. The plurality of heat dissipation strips 6 are evenly distributed. A plurality of heat dissipation holes are provided on the heat dissipation plate 3. The heat dissipation holes are evenly distributed between adjacent heat dissipation strips 6. A plurality of connecting blocks 7 are installed on the limiting thin plate 2. The plurality of connecting blocks 7 are symmetrically distributed at the left and right ends of the limiting thin plate 2. The connecting blocks 7 are detachably connected to the limiting thin plate 2. Connecting slots 13 are provided on the connecting blocks 7. The left and right ends of the locking box 1 match the connecting slots 13.
[0024] First, obtain the circuit board 4 that needs to be locked and limited. Control the circuit board 4 to insert the bottom end of the circuit board 4 into the position of the slot opening of the locking slot 5 at the top end of the locking box 1, so that the circuit board 4 is limited. Here, the locking slot 5 includes a slot opening and a slot bottom. The slot bottom is placed at the bottom end of the locking box 1, and a slot 8 is provided at the locking slot 5. The slot 8 includes a slot opening and a slot bottom. The slot opening is communicated with the locking slot 5, and an elastic pad 10 is installed at the slot bottom. Here, the elastic pad 10 is connectable to the limiting block 11. In this way, when the circuit board 4 is inserted, it contacts the limiting block 11. The structure of the limiting block 11 is in a U shape, and the outer edge of the circuit board 4 matches the U-shaped limiting block 11, that is, the contact length between the limiting block 11 and the circuit board 4 is increased, so as to prevent the inserted circuit board 4 from contacting the locking box 1 and the locking box 1 from being damaged during the moving friction of the circuit board 4. Moreover, two blocking strips 9 are installed at the slot opening. The two blocking strips 9 are symmetrically distributed at the left and right ends of the slot 8. The width value of the slot opening is greater than the spacing value of the two blocking strips 9. That is, during the moving work of the circuit board 4, the two blocking strips 9 can block the circuit board 4, so as to prevent the circuit board 4 from disengaging from the limiting block 11 at the slot opening. In this way, the bottom end of the circuit board 4 can be inserted into the slot bottom position, so that the circuit board 4 has carried out the preliminary locking and limiting work. The elastic pad 10 connected to the locking box 1, due to the elastic effect, enables the limiting block 11 to move stably under the influence of the extrusion force when the circuit board 4 is inserted and moved. In this way, the insertion work can be carried out for circuit boards 4 with various width values, that is, it is convenient to replace circuit boards 4 with various width values.
[0025] Then, the limiting thin plate 2 is covered against the rear end of the locking groove 5. The front end of the locking groove 5 is open, and the covering of the limiting thin plate 2 is to further limit the circuit board 4, so that the circuit board 4 only shows the front end. The limiting thin plate 2 here is installed with a heat sink 3 at the rear end, and a number of heat sinks 6 are installed on the heat sink 3, and the heat sinks 6 are evenly distributed. The heat sink 3 is provided with a number of heat dissipation holes, and the heat dissipation holes are evenly distributed between adjacent heat sinks 6. Then, control a number of connecting blocks 7, insert the left and right ends of the locking box 1 into the connecting slots 13 of a number of connecting blocks 7, and a number of connecting blocks 7 can be symmetrically distributed at the left and right ends of the limiting thin plate 2, so that the connection work between the connecting blocks 7 and the limiting thin plate 2 is done well, that is, the connection work between the limiting thin plate 2 and the locking box 1 is done well, that is, the connection work between the heat sink 3 and the locking box 1 is done well, so that the heat sink 3 is facing the rear end of the circuit board 4.
[0026] Finally, the limit strip 12 can be controlled to cover the top of the locking box 1, that is, the limit strip 12 covers the notch at the top of the locking box 1, thereby preventing the circuit board 4 from escaping from the locking box 1 through the notch. In this way, the locking and limiting work of the circuit board 4 is completed, and the limit block 11 and the elastic pad 10 installed in the slot 8 of the locking slot 5 achieve the purpose of facilitating the smooth locking, installation and removal of the circuit board 4.
[0027] In this way, when the circuit board 4 is used, the external electrical connection wires can be electrically connected to the front end of the circuit board 4, and the heat around the circuit board 4 can be dissipated not only through the opening at the front end of the locking groove 5, but also through the heat dissipation holes and the heat dissipation strips 6 on the limiting thin plate 2.
[0028] The limit block 11 and the limit strip 12 here need to be made of hard materials, and of course hard insulating materials are better. This material can be selected as a wooden block, and the detachable connection between the limit block 11 and the locking box 1, the detachable connection between the limit strip 12 and the locking box 1, the detachable connection between the front end of the limit sheet 2 and the locking box 1, and the detachable connection between the connection block 7 and the limit sheet 2 can all be made with screws, which are not only stable and firm, but also easy to install and disassemble. The material of the connection block 7 and the material of the stop strip 9 can be selected from hard stainless steel, which is strong and durable and not easy to be damaged. The material of the limit sheet 2 and the material of the heat sink 3 can be selected from copper with good heat dissipation effect, but the thickness of the limit sheet 2 needs to be very small to facilitate heat transfer, and the heat sink 6 can be selected from commonly used aluminum alloy materials.
