A spliced flexible circuit board

Abstract

This utility model relates to the field of circuit board splicing technology and discloses a splicing flexible circuit board, including two sets of circuit boards. Each set of circuit boards has three sets of equidistantly distributed positioning holes on one side. A splicing frame is distributed between the two sets of circuit boards, and a splicing mechanism is mounted on the splicing frame. The splicing mechanism is supported on both sides by limiting support components. This utility model's technical solution involves placing a splicing frame between the two sets of circuit boards to be spliced, and inserting one end of each set of circuit boards into slots on both sides of the splicing frame. This positions the two sets of circuit boards at the bottom of the two sets of supports, allowing for pre-positioning. Simultaneously, pressing the two sets of supports on the splicing frame pushes two sets of pressure plates vertically downwards along the direction of the limiting grooves, causing three sets of positioning pins on the pressure plates to insert into three sets of positioning holes on one side of the circuit board. This allows the two sets of circuit boards to be quickly positioned on both sides of the splicing frame.

Description

Technical Field

[0001] This utility model relates to the field of circuit board splicing technology, specifically to a splicing flexible circuit board. Background Technology

[0002] Currently, in the field of circuit board manufacturing and application, flexible circuit boards are widely used in various electronic devices that require flexible wiring due to their unique flexibility and bendability. However, with the continuous increase in the functions of electronic devices and the increasing complexity of their structures, the size and shape of a single flexible circuit board often cannot meet the needs of practical applications, especially in situations where large-area wiring or wiring in specific shapes is required. Therefore, how to achieve efficient and stable splicing of multiple flexible circuit boards has become an urgent problem to be solved.

[0003] Traditional circuit board splicing methods often suffer from problems such as complex operation, low splicing efficiency, and unstable splicing quality. For example, some splicing methods require the use of a large number of fasteners such as screws and rivets, which not only increases the splicing cost but may also lead to splicing failure due to loose or damaged fasteners. In addition, traditional splicing methods often make it difficult to ensure precise alignment between circuit boards during the splicing process, which can easily lead to misalignment and offset, affecting the overall performance and reliability of the circuit board.

[0004] Therefore, we propose a splicing flexible circuit board, which effectively solves the problems existing in traditional splicing methods through innovative splicing mechanism and limiting support component design, and realizes efficient and stable splicing of flexible circuit boards. Utility Model Content

[0005] The purpose of this invention is to provide a splicing flexible circuit board that solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a splicing flexible circuit board, comprising a circuit board, wherein the circuit board is provided in two sets, and each set of the two sets of circuit boards has three sets of equidistantly distributed positioning holes on one side. A splicing frame is distributed between the two sets of circuit boards, and a splicing mechanism is installed on the splicing frame. The splicing mechanism is supported on both sides by limiting support components.

[0007] Optionally, the splicing mechanism includes slots opened in the middle of both sides of the splicing frame, abutments movably installed in both sets of slots, pressure plates fixedly installed in the middle of both sets of abutments, and three sets of equidistant positioning pins fixedly installed at the bottom of both sets of pressure plates, wherein both sets of abutments are U-shaped.

[0008] By adopting the above technical solution, the two sets of circuit boards are spliced ​​together.

[0009] Optionally, the multiple sets of positioning pins correspond to each set of positioning holes, and are movably inserted into the inner cavity of a set of slots at one end of the circuit board on one side.

[0010] By adopting the above technical solution, the circuit board can be installed quickly.

[0011] Optionally, the splicing frame has a connecting groove in the middle, and both sides of the connecting groove are connected to two sets of slots.

[0012] By adopting the above technical solution, it is easier to connect wires on the circuit board.

[0013] Optionally, the limiting support assembly includes limiting grooves opened in the middle of both sides of the slot, limiting sliders slidably installed in both sets of limiting grooves, bolts movably installed in the middle of both sets of limiting sliders, positioning bolts threadedly installed on the top of both sets of bolts, and springs sleeved on the bottom of the bolts.

[0014] By adopting the above technical solution, the frame can be fixed.

[0015] Optionally, the sidewalls of two adjacent sets of limiting sliders are fixedly installed on both sides of the abutment, the bottom of each set of bolts is fixedly installed on the bottom of the corresponding limiting slide groove, and the two sides of each set of springs are fixedly installed on the inner wall of the limiting slide groove and the sidewall of the limiting slider, respectively.

[0016] By adopting the above technical solution, the support frame can be supported.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] The technical solution of this application places a splicing frame between two sets of circuit boards that need to be spliced, and inserts one end of each set of circuit boards into slots on both sides of the splicing frame, so that the two sets of circuit boards are distributed at the bottom of the two sets of abutments, which can pre-position the two sets of circuit boards. At the same time, by pressing the two sets of abutments on the splicing frame, the two sets of pressure plates are pushed vertically downward along the direction of the limiting slide groove, so that the three sets of positioning pins on the pressure plates are inserted into the three sets of positioning holes on one side of the circuit board, which can quickly position the two sets of circuit boards on both sides of the splicing frame.

[0019] The two adjacent sets of limit sliders are fixedly installed on both sides of the support frame, and the bottom of each set of bolts is fixedly installed on the bottom of the corresponding limit slide groove. When the operator pushes the pressure plate to insert the positioning pin into the positioning hole, the limit slider in the limit slide groove can limit and support the support frame on one side of the pressure plate, ensuring that the support frame and the pressure plate move vertically up and down. Tightening the positioning nut on the bolt can limit and compress the support frame. After the bottom of the support frame is attached to the top of the circuit board, the circuit board can be firmly fixed between the slot and the support frame. Attached Figure Description

[0025] Please see Figure 1-3 This utility model provides a technical solution: a splicing flexible circuit board, including a circuit board 12, which is provided with two sets of circuit boards 12. Each set of circuit boards 12 has three sets of equidistantly distributed positioning holes 13 on one side. A splicing frame 1 is distributed between the two sets of circuit boards 12. A splicing mechanism is installed on the splicing frame 1. The splicing mechanism is supported on both sides by limiting support components. The splicing mechanism includes slots 11 opened in the middle of both sides of the splicing frame 1, abutments 3 movably installed in both sets of slots 11, pressure plates 31 fixedly installed in the middle of both sets of abutments 3, and three sets of equidistantly distributed positioning pins 32 fixedly installed at the bottom of both sets of pressure plates 31. Both sets of abutments 3 are U-shaped and splice the two sets of circuit boards 12. The multiple sets of positioning pins 32 correspond to each set of positioning holes 13. One end of one side of the circuit board 12 is movably inserted into the cavity of a set of slots 11 to quickly install the circuit board 12.

[0026] By placing a splicing frame 1 between two sets of circuit boards 12 that need to be spliced, and inserting one end of each set of circuit boards 12 into the slots 11 on both sides of the splicing frame 1, the two sets of circuit boards 12 are distributed at the bottom of the two sets of abutments 3, which can pre-position the two sets of circuit boards 12. At the same time, by squeezing the two sets of abutments 3 on the splicing frame 1, the two sets of pressure plates 31 are pushed vertically downward along the direction of the limiting slide groove 2, so that the three sets of positioning pins 32 on the pressure plate 31 are inserted into the three sets of positioning holes 13 on one side of the circuit board 12, the two sets of circuit boards 12 can be quickly positioned on both sides of the splicing frame 1.

[0027] In this technical solution, the limiting support assembly includes limiting grooves 2 opened in the middle of both sides of the slot 11, limiting sliders 21 slidably installed in both sets of limiting grooves 2, bolts 22 movably installed in the middle of both sets of limiting sliders 21, positioning bolts 22 threadedly installed on the top of both sets of bolts 22, and springs 23 sleeved on the bottom of the bolts 22, which can be fixed by the bracket 3.

[0028] When the operator pushes the pressure plate 31 to insert the positioning pin 32 into the positioning hole 13, the limiting slider 21 in the limiting groove 2 can limit and support the abutment 3 on one side of the pressure plate 31, ensuring that the abutment 3 and the pressure plate 31 move vertically up and down. Tightening the positioning nut 24 on the bolt 22 can limit and compress the abutment 3. After the bottom of the abutment 3 is attached to the top of the circuit board 12, the circuit board 12 can be firmly fixed between the slot 11 and the abutment 3.

[0029] In this technical solution, the side walls of two adjacent sets of limiting sliders 21 are fixedly installed on both sides of the support frame 3, the bottom of each set of bolts 22 is fixedly installed on the bottom of the corresponding limiting groove 2, and the two sides of each set of springs 23 are fixedly installed on the inner wall of the limiting groove 2 and the side wall of the limiting slider 21, which can support the support frame 3.

[0030] When the operator tightens the positioning nut 24 on the bolt 22 upwards, the spring 23 installed at the bottom of the bolt 22 can support the abutment 3 and press the abutment 3 against the top of the slot 11.

[0031] In this technical solution, a connecting groove is provided in the middle of the splicing frame 1, and both sides of the connecting groove are connected to two sets of slots 11, which facilitates the connection of wires on the circuit board 12.

[0032] The connecting slots between the two sets of slots 11 can conceal the wires distributed between the two sets of circuit boards 12, greatly improving the neatness of the assembled circuit boards 12.

[0033] In use, first, place the splicing frame 1 between the two sets of circuit boards 12 that need to be spliced, and insert one end of each set of circuit boards 12 into the slots 11 on both sides of the splicing frame 1, so that the two sets of circuit boards 12 are distributed at the bottom of the two sets of abutments 3, which can pre-position the two sets of circuit boards 12. At the same time, press the two sets of abutments 3 on the splicing frame 1, push the two sets of pressure plates 31 vertically downward along the direction of the limiting slide groove 2, so that the three sets of positioning pins 32 on the pressure plate 31 are inserted into the three sets of positioning holes 13 on one side of the circuit board 12, which can quickly position the two sets of circuit boards 12 on both sides of the splicing frame 1. At the same time, the two sets of limiting sliders 2 are used to... The sidewalls are fixedly installed on both sides of the support frame 3, and the bottom of each set of bolts 22 is fixedly installed on the bottom of the corresponding limiting slide groove 2. When the operator pushes the pressure plate 31 to insert the positioning pin 32 into the positioning hole 13, the limiting slider 21 in the limiting slide groove 2 can limit and support the support frame 3 on one side of the pressure plate 31, ensuring that the support frame 3 and the pressure plate 31 move vertically up and down. Tightening the positioning nut 24 on the bolt 22 can limit and squeeze the support frame 3. After the bottom of the support frame 3 is attached to the top of the circuit board 12, the circuit board 12 can be firmly fixed between the slot 11 and the support frame 3.
