Description

Technical Field

[0001] This utility model relates to the field of bakelite frame technology, specifically to a bakelite frame that is easy to install. Background Technology

[0002] Bakelite is a thermosetting plastic molded from phenolic resin powder. It has properties such as high temperature resistance, good insulation, rigidity, corrosion resistance, and dimensional stability, making it an economical and practical component skeleton.

[0003] During installation, disassembly, and transportation, the pins of existing bakelite frames are prone to bending, pulling, and impact. During circuit board layout or repair and debugging, the pins may need to be bent multiple times to accommodate hole positions or for testing. Various reasons can easily lead to breakage of the delicate pins. When a pin breaks, it is usually repaired by installing a flying wire, replacing the entire component, or soldering. Flying wire and soldering operations are difficult and complex, requiring strict repair skills from the staff. Otherwise, it is easy to damage the pins or other surrounding structures during the repair process. In addition, the strength of solder repair is low and it is prone to secondary breakage. The reliability, strength, and conductivity of flying wires are also lower than those of intact pins. Replacing the entire component is wasteful and costly. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an easy-to-install bakelite frame to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bakelite frame that is easy to install, comprising a frame body, wherein the top two sides of the frame body are provided with a top plate, a slot and a locking strip, and the slot is provided with a pin, the outer surface of the top plate is penetrated by a bolt, and the bottom of the top plate is respectively provided with a limiting groove and a locking groove.

[0006] By adopting the above technical solution, when a pin is damaged, the maintenance personnel first remove the component from the circuit board, and then the staff remove the mounting bracket and magnetic core from the component. After preparation, the staff removes the bolts to stop the top plate from being restricted, and then removes the top plate horizontally away from the main frame, thereby stopping the pin from being restricted. At this time, the staff can pull the pin upwards to replace it. During installation, the staff places the pin from top to bottom so that it passes through the slot. Because the pin tip diameter is larger, it prevents the pin from falling downwards. Then, the top plate is horizontally reinstalled. The limiting groove prevents the top plate from colliding with the pin and prevents the pin from falling upwards. Finally, the bolts are reinstalled and tightened to complete the replacement work. The clamping strips and slots work together to provide auxiliary support for the top plate. The clamping strips and slots help to bear the vertical and horizontal forces to prevent the top plate from falling off, increasing the structural strength and effectively preventing the top plate from falling off.

[0007] Furthermore, the bolt abuts against the top plate and is threadedly connected to the main body of the frame.

[0008] By adopting the above technical solution, the top plate is reinstalled horizontally, and the limiting groove prevents the top plate from colliding with the pin and prevents the pin from falling upward. Then, the bolts are reinstalled and tightened to complete the replacement work.

[0009] Furthermore, both the card strip and the card slot are inverted trapezoidal in shape.

[0010] By adopting the above technical solution, the top plate is supported by the combination of clips and slots. The clips and slots help to bear the forces in the vertical and horizontal directions to prevent the top plate from falling off, thereby increasing the structural strength and effectively preventing the phenomenon of top plate falling off.

[0011] Furthermore, the pin is detachably connected to the slot, and the diameter of the pin tip is larger than the diameter of the slot.

[0012] By adopting the above technical solution, the staff places the pins from top to bottom so that they pass through the slot. Since the pin tip has a larger diameter, the pins are prevented from falling downwards.

[0013] Furthermore, the width of the limiting groove is greater than the diameter of the pin tip, and the back of the limiting groove extends through the back of the top plate.

[0014] By adopting the above technical solution, the limiting groove prevents the top plate from colliding with the pin and prevents the pin from falling upward. The back of the limiting groove extends through the back of the top plate, which can further prevent the top plate from colliding with the top of the pin during the back and forth movement.

[0015] Furthermore, a winding groove is provided in the middle of the top of the main frame, and a magnetic core mounting groove is provided in the middle of the outer surface of the main frame.

[0016] By adopting the above technical solution, after the bakelite frame is produced, the coil can be wound into the winding groove by the winding equipment, and the coil lead wire is soldered to the pin. Then, the magnetic core is installed into the magnetic core mounting groove, and finally the mounting bracket and magnetic core are assembled to complete the component production.

[0017] Furthermore, multiple bolts, slots, retaining strips, limiting grooves, and retaining slots are provided, divided into two groups, and the multiple bolts, slots, retaining strips, limiting grooves, and retaining slots in each group are equidistantly distributed.

[0018] By adopting the above technical solution, the connection strength is improved by increasing the connection surface of the structure through the addition of bolts, slots, retaining strips, limiting grooves and retaining grooves.

[0019] Furthermore, the top plate is made of phenolic resin material.

[0020] By adopting the above technical solution, the top plate is also made of bakelite material, and its parameters such as thermal expansion coefficient, heat resistance, and insulation are the same as those of the main frame, and its service life is similar to that of the main frame.

[0021] Furthermore, the bolts are made of PPS-GF material.

[0022] By adopting the above technical solution, the cost is low, and the parameters such as heat resistance, insulation, water absorption and coefficient of thermal expansion are similar to those of bakelite. Moreover, the tensile strength and impact strength are higher than those of bakelite, so it can be used as a bolt to achieve a good fastening effect.

[0023] In summary, the present invention has the following main advantages:

[0024] 1. This utility model, through the design of a pin, slot, top plate, limiting groove, and bolt, allows for easy replacement of a broken pin. When the pin breaks, removing the bolt stops the top plate from limiting its position, and then removing the top plate stops the pin from limiting its position. The pin can then be pulled upwards for replacement. During installation, the pin is placed from top to bottom so that it passes through the slot. Because the pin's tip diameter is larger, it prevents the pin from falling downwards. The top plate is then reinstalled, and the limiting groove prevents the top plate from colliding with the pin and also prevents the pin from falling upwards. Finally, the bolt is reinstalled and tightened to complete the replacement. This design facilitates the installation of a new pin after breakage, resulting in better repair performance.

[0025] 2. This utility model uses clips and slots to provide auxiliary support for the top plate. The clips and slots work together to help bear the forces in the vertical and horizontal directions, preventing the top plate from falling off. This increases the structural strength and effectively prevents the top plate from falling off. It also increases the connection surface of the structure, thereby improving the connection strength.

[0026] 3. The limiting groove of this utility model, due to the setting of the locking strip and the locking groove, allows the top plate to move only in the front and back direction for disassembly and assembly. The back of the limiting groove runs through the back of the top plate, which can further prevent the top plate from colliding with the top of the pin during the front and back movement; and avoid structural conflicts during disassembly and assembly.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] Example 1:

[0036] An easy-to-install bakelite frame, such as Figures 1-5 As shown, the system includes a main frame 1. The top of the main frame 1 has a top plate 5, a slot 7, and a retaining strip 8 on both sides. A pin 4 is located inside the slot 7 and is detachably connected to the slot 7. The diameter of the pin 4's tip is larger than the diameter of the slot 7. A bolt 6 passes through the outer surface of the top plate 5, abutting against the top plate 5 and threadedly connecting the bolt 6 to the main frame 1. A limiting groove 9 and a retaining groove 10 are respectively formed at the bottom of the top plate 5. The width of the limiting groove 9 is larger than the diameter of the pin 4's tip, and the back of the limiting groove 9 extends through the back of the top plate 5. Both the retaining strip 8 and the retaining groove 10 are inverted trapezoidal. When the pin 4 is damaged, the maintenance personnel first remove the component from the circuit board, then remove the mounting bracket and magnetic core from the component. After preparation, the personnel remove the bolt 6 to complete the top plate... After the top plate 5 is positioned at the limit, it is then removed horizontally away from the main frame 1, thus ending the restriction on pin 4. At this point, the worker can pull pin 4 upwards to replace it. During installation, the worker places pin 4 from top to bottom so that it passes through slot 7. Since the top diameter of pin 4 is larger, it prevents pin 4 from falling downwards. Then, the top plate 5 is horizontally reinstalled. The limiting groove 9 prevents the top plate 5 from colliding with pin 4 and prevents pin 4 from falling upwards. Then, the bolt 6 is reinstalled and tightened to complete the replacement work. The clamping strip 8 and the clamping groove 10 work together to provide auxiliary support for the top plate 5. The clamping strip 8 and the clamping groove 10 help to bear the vertical and horizontal forces to prevent the top plate 5 from falling off, increasing the structural strength and effectively preventing the top plate 5 from falling off.

[0037] See Figures 1-4In the above embodiment, a winding groove 2 is provided in the middle of the top of the skeleton body 1, and a magnetic core mounting groove 3 is provided in the middle of the outer surface of the skeleton body 1. After the bakelite skeleton is produced, the coil can be wound in the winding groove 2 by the winding equipment, and the coil lead wire is soldered to the pin 4. Then the magnetic core is installed in the magnetic core mounting groove 3, and finally the mounting bracket and the magnetic core are assembled to complete the production of the component.

[0038] Example 2:

[0039] Based on the above embodiment one, the following settings are now used to increase the connection strength.

[0040] See Figures 1-5 In the above embodiment, multiple bolts 6, slots 7, retaining strips 8, limiting grooves 9 and retaining slots 10 are provided, and they are divided into two groups. The multiple bolts 6, slots 7, retaining strips 8, limiting grooves 9 and retaining slots 10 in each group are equidistantly distributed. By increasing the number of bolts 6, slots 7, retaining strips 8, limiting grooves 9 and retaining slots 10, the connection surface of the structure is increased, thereby improving the connection strength.

[0041] Example 3:

[0042] Based on the above embodiment one, the following settings are now used to increase insulation.

[0043] See Figure 1 , Figure 2 , Figure 3 and Figure 5 In the above embodiments, the top plate 5 is made of phenolic resin material and is also made of bakelite material. The parameters such as thermal expansion coefficient, heat resistance, and insulation are the same as those of the main frame 1, and the service life is similar to that of the main frame 1. The bolt 6 is made of PPS-GF40 material, which is inexpensive and has parameters such as heat resistance, insulation, water absorption and thermal expansion coefficient similar to those of bakelite. Moreover, its tensile strength and impact strength are higher than those of bakelite, so it can play a good fastening role as bolt 6.

[0044] The implementation principle of this utility model is as follows: First, after the bakelite frame is produced, the coil can be wound in the winding groove 2 by the winding equipment, and the coil lead wire is soldered to the pin 4. Then, the magnetic core is installed in the magnetic core mounting groove 3. Finally, the mounting bracket and the magnetic core are assembled to complete the production of the component.

[0045] When pin 4 is damaged, the maintenance personnel first remove the component from the circuit board, and then the staff remove the mounting bracket and magnetic core from the component. After preparation, the staff removes bolt 6 to end the restriction on top plate 5, and then removes top plate 5 horizontally away from the main body 1 of the frame, thereby ending the restriction on pin 4. At this time, the staff can pull pin 4 upward to replace pin 4.

[0046] During installation, the worker places the pin 4 from top to bottom, allowing it to pass through the slot 7. Since the tip of pin 4 has a larger diameter, this prevents pin 4 from falling downwards. Then, the top plate 5 is horizontally reinstalled. The limiting groove 9 prevents the top plate 5 from colliding with pin 4 and also prevents pin 4 from falling upwards. After that, the bolt 6 is reinstalled and tightened to complete the replacement. The clamping strip 8 and the clamping groove 10 work together to provide auxiliary support for the top plate 5. The clamping strip 8 and the clamping groove 10 help to bear the vertical and horizontal forces to prevent the top plate 5 from falling off, increasing the structural strength and effectively preventing the top plate 5 from falling off.
