Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board technology, specifically to a mutual inductance guide rail circuit board. Background Technology
[0002] With the trend of miniaturization, integration, and high speed in electronic devices, circuit boards, as the key carriers for electrical connections of electronic components, directly affect the overall efficiency of the equipment due to their performance and reliability. Mutual inductance rail circuit boards realize non-contact transmission of signals or energy through the principle of electromagnetic induction, and have potential application value in fields such as intelligent automation equipment, medical devices, and rail transportation. Currently, most mutual inductance rail circuit boards are used by welding, which makes secondary disassembly inconvenient after welding, and it is not easy to restore after incorrect splicing. The splicing error tolerance is low, and welding is time-consuming and labor-intensive.
[0003] To address the aforementioned issues, the existing technology (Chinese patent announcement number CN216721674U, announcement date 2022-06-10) for LED double-sided carbon oil guide rail circuit boards, through structural improvements, adopts a snap-fit assembly method instead of the traditional welding assembly method. This not only facilitates installation but also disassembly. In case of incorrect assembly, it can be quickly disassembled and corrected, resulting in a high fault tolerance rate. Furthermore, the snap-fit method allows for more time-saving and labor-saving assembly of the circuit boards, and the operation is simple, requiring no advanced assembly skills from the operators.
[0004] The above solution allows for direct connection via flexible clips during use, and forced separation during disassembly, which improves the ease of connection. However, this method may result in insufficient connection stability, making it easy for the mutual inductance guide rail circuit board to separate under external force when installed in electronic devices, thus affecting its use. Utility Model Content
[0005] The purpose of this utility model is to provide a mutual inductance guide rail circuit board to solve the problem mentioned in the background art. In the process of use, the existing mutual inductance guide rail circuit boards are directly connected by elastic clips and forcibly separated when disassembling. The connection is convenient and the connection stability is insufficient. When the mutual inductance guide rail circuit boards are assembled and installed in electronic devices, they are easy to separate due to external force, which affects the use of the device.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a mutual inductance guide rail circuit board, comprising a circuit board body, a mutual inductance element disposed on the top of the circuit board body, a frame disposed on the outside of the circuit board body, a slot installed on the right side of the frame, and a mating strip disposed on the left side of the frame, wherein adjacent conveying circuit board bodies are connected by a combination of slot and mating strip.
[0007] A positioning element is slidably connected through the top of the slot, and the bottom of the positioning element is inserted into the positioning groove. The positioning groove is opened in the middle of the top surface of the mating strip. Side fixing pins are slidably connected on the inner walls of the front and rear sides of the slot. The side fixing pins are engaged with the fitting grooves, which are correspondingly opened at the front and rear ends of the mating strip.
[0008] Furthermore, a first spring is installed between the top of the positioning member and the top of the slot, the upper half of the positioning member is cylindrical, the lower half of the positioning member is rectangular, and the positioning slot is set as a rectangular structure.
[0009] Furthermore, the circuit board body forms a vertical connection structure through positioning components, and the positioning components form an elastic engagement structure with the positioning groove through a first spring.
[0010] Furthermore, a cylinder is sleeved on the outer side of the middle part of the positioning member, the cylinder is rotatably connected to the inner side of the top of the slot, a protrusion is installed on the outer side of the middle part of the positioning member, the protrusion is slidably connected to the spiral groove, and the spiral groove is opened on the inner wall of the cylinder.
[0011] Furthermore, the cylinder forms a rotating structure through protrusions and spiral grooves, a pull rope is wound around the outside of the cylinder, the bottom of the pull rope is fixedly connected to a side fixing pin, and a second spring is connected between the side fixing pin and the inner wall of the slot.
[0012] Furthermore, an inner cavity is reserved between the frame and the circuit board body, and heat-conducting plates are provided at equal intervals on the top of the inner cavity, with the top of the heat-conducting plates connected to the bottom of the circuit board body.
[0013] Furthermore, ventilation holes are evenly spaced and pass through the front and rear sides of the frame, the heat-conducting plate is configured with a wave-like structure, and heat dissipation holes are evenly spaced on the heat-conducting plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This mutual inductance guide rail circuit board allows for convenient assembly and disassembly during use, and exhibits good stability after assembly. External forces will not cause adjacent mutual inductance guide rail circuit boards to separate. Furthermore, it can increase the heat dissipation of the mutual inductance guide rail circuit board during use, thus avoiding heat loss.
[0016] 1. Furthermore, the mutual inductance element realizes non-contact transmission of signals or energy through the principle of electromagnetic induction. The frame protects the circuit board body, and slots and mating strips are provided on the outer side of the frame. When assembling the circuit board body, the adjacent slots and mating strips are connected and fixed. Pulling the positioning piece at the top of the slot, the first spring is in a stretched state. After the positioning piece moves up, it makes room for the insertion of the slot. Then, the mating strip is inserted into the slot. After releasing the positioning piece, the first spring drives it to reset and move down, thereby engaging with the positioning groove on the mating strip, thus vertically connecting and fixing the adjacent circuit board bodies.
[0017] 2. Furthermore, when the positioning component moves, it moves in the spiral groove through the protrusion, thereby driving the cylinder to rotate. After the cylinder rotates, it drives the side fixing pin to retract synchronously into the inner wall of the slot through the pull rope, thereby compressing the second spring. Later, when the positioning component moves down and resets, the pull rope is released, and the second spring will push the side fixing pin to extend, thereby engaging with the fitting grooves on the front and rear sides of the mating strip, thereby increasing the horizontal connection between the circuit board bodies and improving the stability of the connection between the circuit board bodies.
[0018] 3. Furthermore, when the circuit board itself generates heat, it will be absorbed by the heat-conducting plate. After the air enters through the ventilation holes on the frame, it will carry away the heat on the heat-conducting plate. Combined with the heat dissipation holes on the heat-conducting plate itself, the heat dissipation effect can be further improved. When the air passes between adjacent heat-conducting plates, it can increase the contact area and time between the air and the heat-conducting plate, thereby improving the heat dissipation effect.

The upper half of the positioning member 6 is cylindrical, and the lower half of the positioning member 6 is rectangular. The positioning groove 8 is set as a rectangular structure. The circuit board body 1 forms a vertical connection structure through the positioning member 6 and the positioning member 6. The positioning member 6 forms an elastic engagement structure with the positioning groove 8 through the first spring 7.
[0031] During docking, first pull the positioning piece 6 at the top of the slot 4. At this time, the first spring 7 is in a stretched state. After the positioning piece 6 moves up, it makes room for the insertion of the slot 4. Then, insert the docking strip 5 into the slot 4.

Combined with the heat dissipation holes 18 of the heat-conducting plate 17 itself, the heat dissipation effect can be further improved.
