Description

Technical Field

[0001] This utility model relates to the field of structural technology of ribbon cable connectors, specifically to a ribbon cable connector, an infrared touch frame, and an infrared touch screen. Background Technology

[0002] Flexible flat cable (FFC) is a data transmission cable made of flat copper foil laminated with insulating material. It is small in size, light in weight, and flexible, making it suitable for data transmission between moving parts and motherboards, between PCBs, and in miniaturized electrical equipment. Therefore, flexible flat cables are also commonly used in the assembly and production of electronic devices. However, in the current technology, there is a lack of indicative markings for the alignment of flexible flat cables, making it difficult to identify whether the insertion angle of the flexible flat cable is abnormal. An abnormal insertion angle of the flexible flat cable can easily cause pins to fail to connect or adjacent pins to short circuit, resulting in the failure of the board's functions. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings and deficiencies in the prior art and provide a ribbon cable connector, an infrared touch frame, and an infrared touch screen. The flexible ribbon cable is aligned with the ribbon cable connector's connector through the ribbon cable alignment mark, which helps to improve the efficiency and accuracy of visual inspection of the flexible ribbon cable assembly.

[0004] The first embodiment of this utility model provides a ribbon cable connector, including: a circuit board and a ribbon cable connector; the ribbon cable connector is disposed on the circuit board, and the ribbon cable connector is provided with a ribbon cable socket for connecting to a flexible ribbon cable;

[0005] The circuit board is provided with a ribbon cable connection alignment mark; the ribbon cable connection alignment mark is aligned with the orientation of the ribbon cable socket, and the flexible ribbon cable is inserted into the ribbon cable socket of the ribbon cable socket through the ribbon cable connection alignment mark.

[0006] Compared to existing technologies, the ribbon cable connector of this utility model includes a circuit board and a ribbon cable socket disposed on the circuit board. The circuit board is provided with a ribbon cable connection alignment mark that aligns with the ribbon cable socket of the ribbon cable socket. The flexible ribbon cable is aligned and inserted into the ribbon cable socket through the ribbon cable connection alignment mark. This allows users to easily check whether the flexible ribbon cable is aligned and inserted into the ribbon cable socket according to the ribbon cable connection alignment mark. It can accurately and efficiently determine whether the connection between the flexible ribbon cable and the ribbon cable socket is abnormal, thus improving the efficiency and accuracy of visual inspection of flexible ribbon cable assembly.

[0007] In one embodiment, the ribbon cable connection alignment mark includes two first alignment marks; the two first alignment marks are located at a position away from the ribbon cable socket; the two first alignment marks are located opposite each other on both sides of the circuit board; When the flexible flat cable is aligned with the flat cable socket, the two sides of the protective sleeve of the flexible flat cable are aligned with the edges of the two first alignment marks.

[0008] In this embodiment, by comparing the two first alignment marks located on both sides of the circuit board with the ribbon cable connector away from the connector, it is possible to quickly determine whether the two sides of the protective sleeve of the flexible ribbon cable are aligned with the edges of the two first alignment marks, thereby quickly determining whether there is an abnormal connection between the flexible ribbon cable and the ribbon cable connector of the connector due to misalignment.

[0009] In one embodiment, the ribbon cable connection alignment mark includes a second alignment mark; the second alignment mark is located near the ribbon cable socket of the ribbon cable connector; when the flexible ribbon cable is aligned with the ribbon cable socket of the ribbon cable connector, the reinforcing plate of the flexible ribbon cable is aligned with the second alignment mark.

[0010] In this embodiment, by using the second alignment mark of the ribbon cable connector adjacent to the ribbon cable socket, it is possible to compare whether the reinforcing plate of the flexible ribbon cable is aligned with the second alignment mark, thereby quickly determining whether there is an abnormal connection between the flexible ribbon cable and the ribbon cable connector of the ribbon cable socket due to misalignment.

[0011] In one embodiment, the ribbon cable connection alignment mark includes two first alignment marks and a second alignment mark; the two first alignment marks are located away from the ribbon cable socket of the ribbon cable connector; the second alignment mark is located adjacent to the ribbon cable socket of the ribbon cable connector. When the flexible flat cable is aligned with the connector of the flat cable socket, the two sides of the protective sleeve of the flexible flat cable are aligned with the edges of the two first alignment marks, and the reinforcing plate of the flexible flat cable is aligned with the second alignment mark.

[0012] In this embodiment, by comparing the two first alignment marks located on both sides of the circuit board away from the ribbon cable connector and the second alignment mark of the ribbon cable connector adjacent to the ribbon cable connector, it is possible to more comprehensively compare and determine whether the two sides of the protective sleeve of the flexible ribbon cable are aligned with the edges of the two first alignment marks and whether the reinforcing plate of the flexible ribbon cable is aligned with the second alignment mark, thereby more accurately determining whether there is an abnormal connection between the flexible ribbon cable and the ribbon cable connector of the ribbon cable connector that is not aligned.

[0013] In one implementation, the second alignment identifier includes a printing wire block.

[0014] In this embodiment, it is possible to compare whether the reinforcing plate of the flexible flat cable is aligned with the printed wire block of the second alignment mark, so as to quickly determine whether there is an abnormal connection between the flexible flat cable and the flat cable socket without affecting the connection relationship between the flexible flat cable and the flat cable socket.

[0015] In one implementation, the first alignment identifier includes a printing wire block.

[0016] In this embodiment, the edges of the two first alignment marks on the protective sleeve of the flexible flat cable can be compared to determine whether there is an abnormal connection between the flexible flat cable and the flat cable socket without affecting the connection relationship between the flexible flat cable and the flat cable socket.

[0017] In one implementation, the first alignment mark extends toward the edge of the circuit board in a direction away from the ribbon cable connector.

[0018] In this embodiment, by extending the first alignment mark, the alignment length between the two sides of the protective sleeve of the flexible flat cable and the two first alignment marks is increased, which can improve the accuracy of visual inspection of the flexible flat cable assembly.

[0019] In one implementation, the first alignment mark includes alignment columns; when the flexible flat cable is aligned and plugged into the flat cable socket, the protective sleeve of the flexible flat cable abuts against the two alignment columns.

[0020] In this embodiment, the alignment column of the first alignment mark restricts the range of motion of the protective sleeve of the flexible ribbon cable inserted into the ribbon cable socket, so that the flexible ribbon cable is aligned with the ribbon cable socket and inserted, thus avoiding abnormal insertion angle between the flexible ribbon cable and the ribbon cable socket.

[0021] The second embodiment of this application provides an infrared touch frame, including: a frame body, a first infrared board, a second infrared board, and a flexible flat cable; The first infrared board and the second infrared board are respectively disposed on the two sides of the frame; the first infrared board and the second infrared board each include the ribbon cable connectors as described above; the ribbon cable connector of the first infrared board is connected to the ribbon cable connector of the second infrared board via the flexible ribbon cable.

[0022] Compared to existing technologies, the infrared touch frame of this invention includes ribbon cable connectors as described above in both its first and second infrared boards. Therefore, the flexible ribbon cable is aligned with the ribbon cable connector of the connector via the alignment mark, allowing users to easily check whether the flexible ribbon cable is aligned with the connector based on the alignment mark. This enables accurate and efficient judgment of whether the connection between the flexible ribbon cable and the connector is abnormal, improving the efficiency and accuracy of visual inspection of the flexible ribbon cable assembly in the infrared touch frame.

[0023] The third embodiment of this application provides an infrared touch screen, including: a display screen, and an infrared touch frame as described above; the infrared touch frame is arranged around the edge of the display screen.

[0024] Compared to existing technologies, the infrared touch screen of this invention includes a ribbon cable connector as described above in both the first and second infrared boards of its infrared touch frame. Therefore, the flexible ribbon cable is aligned with the ribbon cable connector's connector via the alignment mark, allowing users to easily check whether the flexible ribbon cable is aligned with the connector's connector. This enables accurate and efficient judgment of any abnormalities in the connection between the flexible ribbon cable and the connector, improving the efficiency and accuracy of visual inspection of the flexible ribbon cable assembly in the infrared touch screen.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Flexible flat cable (FFC) is a data transmission cable made of flat copper foil laminated with insulating material. It is small in size, light in weight, and flexible, making it suitable for data transmission between moving parts and motherboards, between PCBs, and in miniaturized electrical equipment. Therefore, flexible flat cables are also commonly used in the assembly and production of electronic devices. However, in the current technology, there is a lack of indicative markings for the alignment of flexible flat cables, making it difficult to identify whether the insertion angle of the flexible flat cable is abnormal. An abnormal insertion angle of the flexible flat cable can easily cause pins to fail to connect or adjacent pins to short circuit, resulting in the failure of the board's functions.

[0030] Please see Figure 1 In the existing technology, in the absence of indicative markings, users can only judge whether the flexible flat cable and the flat cable socket are properly connected by visual inspection and experience. This has technical defects of low efficiency and poor accuracy of visual inspection.

[0031] The circuit board of this utility model is provided with a ribbon cable connection alignment mark for aligning the ribbon cable socket of the ribbon cable connector. This allows users to easily check whether the ribbon cable is aligned with the ribbon cable socket of the ribbon cable connector based on the ribbon cable connection alignment mark. It can accurately and efficiently determine whether the connection between the ribbon cable and the ribbon cable socket is abnormal, thereby improving the efficiency and accuracy of visual inspection of ribbon cable assembly.

[0032] Please see Figure 2 This is a schematic diagram of the ribbon cable connector 10 according to the first embodiment of the present utility model. The ribbon cable connector 10 includes: a circuit board 11 and a ribbon cable socket 13; the ribbon cable socket 13 is disposed on the circuit board 11 and has a ribbon cable socket for connecting to a flexible ribbon cable.

[0033] The circuit board 11 is provided with a ribbon cable connection alignment mark 111; the ribbon cable connection alignment mark 111 is aligned with the orientation of the ribbon cable socket, and the flexible ribbon cable is connected to the ribbon cable socket of the ribbon cable connector 13 through the ribbon cable connection alignment mark 111.

[0034] The full name of circuit board 11 is printed circuit board (PCB), which is the core component of electronic equipment. It realizes the electrical connection and mechanical fixation of electronic components on an insulating substrate through conductive lines.

[0035] The ribbon cable connector 13 is used for electronic components that are electrically connected to a flexible flat cable. In this embodiment, the ribbon cable connector 13 is disposed on the circuit board 11. The electronic circuits on the circuit board 11 are connected to the flexible flat cable through the ribbon cable connector 13, enabling the electronic circuits on the circuit board 11 to exchange information with the outside world through the flexible flat cable. Specifically, the ribbon cable connector 13 is provided with a ribbon cable socket, and the ribbon cable connector 13 is electrically connected to the flexible flat cable through the ribbon cable socket.

[0036] Flexible flat panel cables are data transmission cables made by laminating flat copper foil with insulating material. They are small, lightweight, and flexible, making them suitable for data transmission between moving parts and motherboards, between PCBs, and in miniaturized electrical devices. The basic structure of a flexible flat panel cable mainly includes conductors, insulation layers, and a protective sheath. The conductors, which can be copper or tin-plated wire, are responsible for transmitting electrical signals. The insulation layer, located between the conductors, can be made of polyimide or other high-temperature resistant materials to ensure electrical isolation between the conductors. The protective sheath, located on the outermost layer of the flexible flat panel cable, is usually made of PVC or other wear-resistant and bend-resistant materials, providing physical protection and preventing external environmental influences on the internal circuitry.

[0037] The ribbon cable connection alignment mark 111 is used to indicate whether the ribbon cable is aligned and plugged into the ribbon cable socket 13. For example, the ribbon cable connection alignment mark 111 can be a different color from the circuit board 11 to indicate whether the ribbon cable is aligned and plugged into the ribbon cable socket 13.

[0038] Please see Figure 2 and Figure 3 Compared with the prior art, the ribbon cable connector 10 of this utility model includes a circuit board 11 and a ribbon cable socket 13 disposed on the circuit board 11. The circuit board 11 is provided with a ribbon cable connection alignment mark 111 for aligning with the ribbon cable socket of the ribbon cable socket 13. The flexible ribbon cable is aligned and plugged into the ribbon cable socket 13 through the ribbon cable connection alignment mark 111. This allows users to easily check whether the flexible ribbon cable is aligned and plugged into the ribbon cable socket 13 according to the ribbon cable connection alignment mark 111. It can accurately and efficiently determine whether the connection between the flexible ribbon cable and the ribbon cable socket is abnormal, thus improving the efficiency and accuracy of visual inspection of flexible ribbon cable assembly.

[0039] Please see Figure 4 In one feasible embodiment, the ribbon cable connection alignment mark 111 includes two first alignment marks 1111; the two first alignment marks 1111 are arranged at the ribbon cable socket away from the ribbon cable connector 13; the two first alignment marks 1111 are located opposite each other on both sides of the circuit board 11. When the flexible flat cable is aligned with the flat cable socket 13, the two sides of the protective sleeve of the flexible flat cable are aligned with the edges of the two first alignment marks 1111.

[0040] Please see Figure 4 and Figure 5 Since the protective sleeve of the flexible flat cable aligns with the edges of the two first alignment marks 1111 when it is plugged into the flat cable socket 13, the protective sleeve of the flexible flat cable will also tilt relative to the edges of the two first alignment marks 1111 when it is plugged into the flat cable socket at an angle. This allows users to quickly determine whether the flexible flat cable is plugged into the flat cable socket by directly looking at the protective sleeve of the flexible flat cable and the edges of the two first alignment marks 1111.

[0041] In this embodiment, by comparing the two first alignment marks 1111 located on both sides of the circuit board 11 away from the ribbon cable connector 13, it is possible to quickly determine whether the two sides of the protective sleeve of the flexible ribbon cable are aligned with the edges of the two first alignment marks 1111, thereby quickly determining whether there is an abnormal connection between the flexible ribbon cable and the ribbon cable connector 13 due to misalignment.

[0042] Please see Figure 6In one feasible embodiment, the ribbon cable connection alignment mark 111 includes a second alignment mark 1113; the second alignment mark 1113 is disposed at a position adjacent to the ribbon cable socket of the ribbon cable connector 13; when the ribbon cable is aligned with the ribbon cable socket of the ribbon cable connector 13, the reinforcing plate of the ribbon cable is aligned with the second alignment mark 1113.

[0043] Because most flexible flat cables are relatively thin, inserting the connector end into the connector of the flat cable socket 13 is difficult and results in poor connection stability. The reinforcing plate, located at the connector end of the flexible flat cable, adjusts the thickness and rigidity of the connector end, ensuring sufficient density when the connector end is inserted into the connector, thus improving the connection stability between the flexible flat cable and the connector 13. When a flexible flat cable with a reinforcing plate is aligned and inserted into the connector of the connector 13, part of the reinforcing plate will protrude outside the connector. By observing the correspondence between the second alignment mark 1113 and the exposed reinforcing plate, it is possible to quickly determine whether there is an abnormal connection due to misalignment between the flexible flat cable and the connector of the connector 13.

[0044] Please see Figure 6 and Figure 7 In this embodiment, by using the second alignment mark 1113 of the ribbon cable connector adjacent to the ribbon cable socket 13, it is possible to compare whether the reinforcing plate of the flexible ribbon cable is aligned with the second alignment mark 1113, thereby quickly determining whether there is an abnormal connection between the flexible ribbon cable and the ribbon cable connector of the ribbon cable socket 13 due to misalignment.

[0045] Please see Figure 8 In one feasible embodiment, the ribbon cable connection alignment mark 111 includes two first alignment marks 1111 and a second alignment mark 1113; the two first alignment marks 1111 are located at the ribbon cable socket away from the ribbon cable connector 13; the second alignment mark 1113 is located at the ribbon cable connector adjacent to the ribbon cable connector 13. When the flexible flat cable is aligned with the flat cable socket 13, the two sides of the protective sleeve of the flexible flat cable are aligned with the edges of the two first alignment marks 1111, and the reinforcing plate of the flexible flat cable is aligned with the second alignment mark 1113.

[0046] Among them, the two first alignment marks 1111 and the second alignment mark 1113 can be used to compare with the two sides of the protective sleeve of the flexible flat cable and the reinforcing plate of the flexible flat cable, respectively, to more comprehensively compare and judge whether the flexible flat cable is aligned and plugged into the flat cable socket 13, thereby improving the accuracy of visual inspection.

[0047] Please see Figure 8 and Figure 9In this embodiment, by comparing the two first alignment marks 1111 located on both sides of the circuit board 11 away from the ribbon cable connector 13 and the second alignment mark 1113 adjacent to the ribbon cable connector 13, it is possible to more comprehensively compare and determine whether the two sides of the protective sleeve of the flexible ribbon cable are aligned with the edges of the two first alignment marks 1111 and whether the reinforcing plate of the flexible ribbon cable is aligned with the second alignment mark 1113. This allows for a more accurate determination of whether there is an abnormal connection between the flexible ribbon cable and the ribbon cable connector 13 due to misalignment.

[0048] In one feasible embodiment, the second alignment identifier 1113 includes a printing wire block.

[0049] The silkscreen block refers to the PCB silkscreen (also known as the character layer or white ink layer), which is a non-conductive marking layer formed on the surface of the printed circuit board 11 through a printing process. In this embodiment, the color of the silkscreen block is different from the color of the circuit board 11. For example, if the surface color of the circuit board 11 is green or blue, the color of the silkscreen block can be white, red, yellow, etc.

[0050] In this embodiment, it is possible to compare whether the reinforcing plate of the flexible flat cable is aligned with the printed wire block of the second alignment mark 1113, so as to quickly determine whether there is an abnormal connection between the flexible flat cable and the flat cable socket 13 without affecting the connection relationship between the flexible flat cable and the flat cable socket.

[0051] In one feasible embodiment, the first alignment identifier 1111 includes a printing wire block.

[0052] In this embodiment, the edges of the two first alignment marks 1111 on both sides of the protective sleeve of the flexible flat cable can be compared to determine whether there is an abnormal connection between the flexible flat cable and the flat cable socket 13 without affecting the connection relationship between the flexible flat cable and the flat cable socket.

[0053] In one feasible embodiment, the first alignment mark 1111 extends toward the edge of the circuit board 11 in a direction away from the ribbon cable connector 13.

[0054] The longer the two first alignment marks 1111 extend, the longer the alignment length between the two sides of the protective sleeve of the flexible flat cable and the two first alignment marks 1111.

[0055] In this embodiment, by extending the first alignment mark 1111, the alignment length between the two sides of the protective sleeve of the flexible flat cable and the two first alignment marks 1111 is increased, which can improve the accuracy of visual inspection of the flexible flat cable assembly.

[0056] In one feasible embodiment, the first alignment mark 1111 includes alignment columns; when the flexible flat cable is aligned and plugged into the flat cable socket 13, the protective sleeve of the flexible flat cable abuts against the two alignment columns.

[0057] Among them, the alignment bar is an insulating alignment bar with a three-dimensional spatial structure. A ribbon cable accommodating area is formed between the alignment bars of the two first alignment marks 1111 to accommodate the protective sleeve of the flexible ribbon cable. When the flexible ribbon cable is aligned and plugged into the ribbon cable socket, the two sides of the protective sleeve of the flexible ribbon cable abut against the alignment bars of the two first alignment marks 1111 respectively.

[0058] In this embodiment, the alignment column of the first alignment mark 1111 restricts the range of motion of the protective sleeve of the flexible flat cable plugged into the flat cable socket of the flat cable connector 13, so that the flexible flat cable is aligned with the flat cable socket of the flat cable connector 13 and is plugged in, thus avoiding the situation where the plugging angle of the flexible flat cable and the flat cable socket of the flat cable connector 13 is abnormal.

[0059] Please see Figure 10 The second embodiment of this application provides an infrared touch frame 20, including: a frame 21, a first infrared board, a second infrared board, and a flexible flat cable; The first infrared board and the second infrared board are respectively disposed on the two sides of the frame 21; the first infrared board and the second infrared board each include the ribbon cable connector 10 as described above; the ribbon cable connector 10 of the first infrared board is connected to the ribbon cable connector 10 of the second infrared board via a flexible ribbon cable.

[0060] The infrared touch frame 20 is an interactive device that uses an infrared matrix to achieve contactless touch control. It identifies the position of objects through an infrared array and is widely used in large-size displays, industrial control, and public information terminals. For example, one vertical frame of the infrared touch frame 20 is equipped with an infrared emitter, and the other vertical frame is equipped with an infrared receiver. One horizontal frame of the infrared touch frame 20 is equipped with an infrared emitter, and the other horizontal frame is equipped with an infrared receiver, forming a grid-like detection network (X / Y direction). By scanning the position where an object (such as a finger, pen, etc.) blocks the infrared light, the touch coordinates are calculated.

[0061] In one embodiment, the first infrared board can be a board that controls the operation of infrared emitting tubes arranged on the vertical frame, and the second infrared board can be a board that controls the operation of infrared emitting tubes arranged on the horizontal frame. Since the first infrared board and the second infrared board are connected by a flexible flat cable, the first infrared board and the second infrared board can exchange data through the flexible flat cable, so that the infrared emitting tubes corresponding to the first infrared board and the second infrared board can be started at the same time.

[0062] In one embodiment, the first infrared board can be a board that controls the operation of infrared receivers arranged on the vertical frame, and the second infrared board can be a board that controls the operation of infrared receivers arranged on the horizontal frame. Since the first and second infrared boards are connected by a flexible flat cable, they can exchange data through the cable. The first infrared board transmits the first touch coordinates detected by the corresponding infrared receiver to the second infrared board, and the second infrared board transmits the first touch coordinates and the second touch coordinates detected by the corresponding infrared receiver to the central control board of the infrared touch frame 20 to accurately obtain the touch coordinates corresponding to the touch operation. The central control board (also called the control board or main control module) is the core processing unit of the infrared touch system, undertaking key functions such as signal analysis, device linkage, and system control.

[0063] Compared to existing technologies, the infrared touch frame 20 of this utility model includes a ribbon cable connector 10 as described above in both its first and second infrared boards. Therefore, the flexible ribbon cable is aligned and plugged into the ribbon cable socket 13 via the ribbon cable alignment mark 111. This allows users to easily check whether the flexible ribbon cable is aligned and plugged into the ribbon cable socket 13 based on the ribbon cable alignment mark 111. This enables accurate and efficient judgment of whether the connection between the flexible ribbon cable and the ribbon cable socket is abnormal, improving the efficiency and accuracy of visual inspection of the flexible ribbon cable assembly of the infrared touch frame 20.

[0064] Please see Figure 11 The third embodiment of this application provides an infrared touch screen 300, including: a display screen 301, and an infrared touch frame 20 as described above; the infrared touch frame 20 is arranged around the edge of the display screen 301.

[0065] Among them, the display screen 301 of the infrared touch screen 300 is a display device with display function. In this embodiment, the display screen 301 of the infrared touch screen 300 switches to the display screen corresponding to the touch operation according to the touch coordinates transmitted by the infrared touch frame 20, including but not limited to opening a folder, opening a file, opening a browser, writing, drawing lines, etc.

[0066] Compared to existing technologies, the infrared touch screen 300 of this utility model includes a ribbon cable connector 10 as described above in both the first and second infrared boards of its infrared touch frame 20. Therefore, the flexible ribbon cable is aligned and plugged into the ribbon cable socket 13 via the ribbon cable alignment mark 111. This allows users to easily check whether the flexible ribbon cable is aligned and plugged into the ribbon cable socket 13 based on the ribbon cable alignment mark 111. This enables accurate and efficient judgment of whether the connection between the flexible ribbon cable and the ribbon cable socket is abnormal, improving the efficiency and accuracy of visual inspection of the flexible ribbon cable assembly of the infrared touch screen 300.
