Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a flexible integrated signal connection device. Background Technology

[0002] Signal connection devices, serving as channels for signal transmission between devices and instruments, are an indispensable part of electronic equipment. Currently, common signal connection methods between devices and instruments include gold finger plug-in structures and cable connection structures.

[0003] Gold finger connectors are typically used for signal transmission between printed circuit board (PCB) assemblies. One PCB assembly has a gold finger connector, and the other has a gold finger socket. The connector and socket are then plugged into each other. Examples include external expansion modules and motherboards in computers. This structure requires at least one PCB assembly to be movable. Furthermore, the weight of the PCB assembly increases the stress on the gold finger connector, affecting reliability. Therefore, after plugging in, an additional fixing structure is needed to secure the PCB assembly. This is not only cumbersome to operate but also requires high positional accuracy and is costly.

[0004] Cable connection structures are typically located between two geographically distant devices. Connectors are fixed at both ends of the cable, and the devices have matching sockets to connect the two fixed devices. However, this structure suffers from insufficient adaptability due to the fixed connector models and specifications. Furthermore, because cables are subject to repeated bending during use, damage to any part of the cable renders both the cable and the connectors at both ends unusable, resulting in high operating costs. Utility Model Content

[0005] The technical problem to be solved by this utility model is: how to improve the convenience of signal connection between equipment and instruments, while improving adaptability and reducing costs.

The surface of the plug plate is provided with multiple conductive sheets, which are spaced apart along the width direction of the strip cable. The plug plate is inserted into the connector and connected to the connector via the multiple conductive sheets. The strip cable is provided with multiple signal channels, which are connected to the multiple conductive sheets one by one.

[0008] The beneficial effects of this utility model are:

[0009] This invention enables signal connection between two devices across space via a connector and a flexible ribbon cable, offering excellent convenience. The connection device does not bear the weight of the devices, and no additional fixation is required after insertion, resulting in low cost and high reliability. Furthermore, the ribbon cable's end connects to the connector via a plug-in rigid plate, which can accommodate connectors of different specifications for the same protocol, improving adaptability. Both the ribbon cable and connector can be replaced individually if damaged, avoiding complete scrapping and resource waste.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the plug board is a printed circuit board, and the printed circuit board has printed lines inside. One end of each printed line is connected to a corresponding signal channel, and the other end is connected to a corresponding conductive sheet.

[0020] This facilitates the connection of the printed circuit board inside the plug to the conductive sheet, resulting in uniform spacing of the printed circuit board, good product consistency, and a low failure rate.

[0021] Furthermore, the front side of the plug rigid plate is provided with 16 conductive plates, and the back side of the plug rigid plate is provided with 15 conductive plates.

[0022] Connectors that can accommodate 31-pin aviation plugs, such as the J20J-31TJ-JC aviation plug, have good adaptability.

[0023] Furthermore, the conductive sheets are arranged along the length of the strip cable, with the length L of the conductive sheets being 1.9mm to 2.1mm, the width n of the conductive sheets being 0.6mm to 0.7mm, and the distribution spacing m of the conductive sheets being 0.9mm to 1mm.

[0036] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0037] This utility model refers to Figure 1-5 .

[0038] This utility model provides a flexible integrated signal connection device, including a strip cable 1 and a connector 3. At least one end of the strip cable 1 is fixed with a plug rigid plate 2. The surface of the plug rigid plate 2 is provided with multiple conductive pieces 4, which are spaced apart along the width direction of the strip cable 1. The plug rigid plate 2 is inserted into the connector 3 and is signal connected to the connector 3 through the multiple conductive pieces 4. The strip cable 1 is provided with multiple signal channels, and the multiple signal channels are connected to the multiple conductive pieces 4 one by one.

[0039] principle:

[0040] The surface of the plug hard board 2 forms a gold finger structure through multiple conductive plates 4, which is then inserted with the connector 3 to achieve signal connection. During installation, the plug hard board 2 can be inserted with the connector 3, and then the connector 3 can be inserted with the plug / socket on the equipment / instrument; alternatively, the connector 3 can be inserted into the plug / socket on the instrument first, and then the plug hard board 2 can be inserted with the connector 3. After the plug hard board 2 and connector 3 are inserted, screw connections, adhesive bonding, or other structural reinforcements can be added as needed. The connector 3 protocol uses existing parameters, and the protocol is uniform for specific models of connector 3. When the connector 3 protocol is compatible with the number of conductive plates 4, the number of pins 7 of the connector 3 is generally the same as the number of conductive plates 4, and the arrangement of the contact plates corresponding to the pins 7 of the connector 3 remains unchanged. Therefore, the arrangement of the conductive plates 4 on the plug hard board 2 does not need to be changed, and they can make one-to-one contact with the contact plates of the connector 3 during insertion.

[0041] Note: Connector 3 is either a plug or a socket. When connector 3 is a plug, it is inserted into the corresponding socket on the equipment or instrument; when connector 3 is a socket, it is inserted into the corresponding plug on the equipment or instrument. When both ends of the ribbon cable 1 are equipped with connector 3, it can be configured such that both ends of connector 3 are plugs, both ends of connector 3 are sockets, one end of connector 3 is a plug and the other end of connector 3 is a socket, etc., to adapt to the use of special structures and special spaces.

[0042] This invention enables signal connection between two devices across space via connector 3 and flexible ribbon cable 1, offering excellent convenience. Furthermore, the connection device does not bear the weight of the devices, and no additional fixing is required after insertion, resulting in low cost and high reliability. Simultaneously, the end of ribbon cable 1 connects to connector 3 via a plug rigid plate 2, which can accommodate connectors 3 of different specifications for the same protocol, improving adaptability. Both ribbon cable 1 and connector 3 can be replaced individually when damaged, avoiding complete scrapping and resource waste.

[0043] Furthermore, the plug rigid board 2 is a printed circuit board, and the printed circuit board has printed lines inside. One end of each printed line is connected to a corresponding signal channel, and the other end is connected to a corresponding conductive sheet 4.

[0044] The signal channel is connected to the conductive sheet 4 through the printed circuit inside the printed circuit board, which is easy to manufacture, has good product consistency, is not easy to corrode, and has strong signal transmission reliability.

[0045] Furthermore, the plug rigid plate 2 is welded to the ribbon cable 1.

[0046] This improves the connection stability between the ribbon cable 1 and the plug rigid plate 2, resulting in a longer service life.

[0047] Furthermore, the strip cable 1 is a flexible printed circuit board, and its multiple signal channels are printed circuits.

[0048] Its flexible structure can adapt to cross-space connections, and through printed circuits, it can avoid the misalignment of the cable cores, resulting in a long service life and high reliability.

[0049] Furthermore, multiple conductive sheets 4 are provided on both sides of the plug rigid plate 2.

[0050] It facilitates full utilization of both sides of the plug rigid plate 2, resulting in high signal transmission efficiency and a compact structure.

[0051] Furthermore, the front side of the plug rigid plate 2 is provided with n conductive sheets 4, and the back side of the plug rigid plate 2 is provided with n-1 conductive sheets 4, where n is an integer greater than 3; the conductive sheets 4 on both sides of the plug rigid plate 2 are staggered.

[0052] Note: The distribution is staggered, meaning that each conductive piece 4 on the back of the plug rigid plate 2 is located between two adjacent conductive pieces 4 on the front of the plug rigid plate 2.

[0053] This facilitates the connection of the printed circuit board 2 inside the plug with the conductive sheet 4, resulting in uniform spacing of the printed circuit board, good product consistency, and low failure rate.

[0054] Furthermore, the front side of the plug rigid plate 2 is provided with 16 conductive plates 4, and the back side of the plug rigid plate 2 is provided with 15 conductive plates 4.

[0055] Connector 3 is compatible with 31-pin aviation plugs / sockets, such as the J20J-31TJ-JC aviation plug / socket, and has good adaptability.

[0056] Note: Aviation connectors come in various numbers of pins, such as 3, 4, 5, 6, 8, 12, 14, etc. A single number of pins can correspond to or define a new transmission protocol. For the same number of pins, the connector housing can be made in various shapes and sizes, thus resulting in connectors of the same protocol but different specifications.

[0057] Furthermore, the conductive sheet 4 is arranged along the length direction of the strip cable 1, the length L of the conductive sheet 4 is 1.9mm to 2.1mm, the width n of the conductive sheet 4 is 0.6mm to 0.7mm, and the distribution spacing m of the conductive sheet 4 is 0.9mm to 1mm.

[0058] Preferably, the length L of the conductive sheet 4 is 2mm, the width n of the conductive sheet 4 is 0.65mm, and the distribution spacing m of the conductive sheets 4 is 0.95mm.

[0059] It is easy to adapt to standardized gold finger structures and is convenient to connect.

[0060] Furthermore, the connector 3 includes a base 5, on one side of which a housing 6 and multiple pins 7 are fixed, with the pins 7 located inside the housing 6; on the other side of the base 5, a socket 8 is provided, with a socket 8 having a mortise that matches the shape of the plug rigid plate 2, and contact pieces on the inner wall of the mortise, each contact piece corresponding to and connected to a pin 7; each contact piece is arranged corresponding to a conductive piece 4.

[0061] Preferably, the inner wall of the joint is a printed circuit board with printed lines inside. Each contact piece corresponds to a pin 7 and is connected through the printed lines.

[0062] During installation, the conductive sheet 4 and the pin 7 are connected and transmit signals through the contact sheet. The conductive sheet 4 and the contact sheet have a large contact area, resulting in a stable signal. The structure of the housing 6 and the pin 7 can be matched with the standardized connector 3 plug / socket, making installation convenient.

[0063] Furthermore, both ends of the ribbon cable 1 are provided with plug plates 2; the connector 3 is provided with front and back markings 9 on both sides.

[0064] Note: The mark 9 on both sides can be raised, printed, or have other structures, and the content can be text, patterns, numbers, or other symbols.

[0065] With plug hard plates 2 at both ends of the ribbon cable 1, the types of connectors 3 at both ends of the ribbon cable 1 can be flexibly set, such as both ends of the connector 3 being plugs, both ends of the connector 3 being sockets, one end of the connector 3 being a plug and the other end of the connector 3 being a socket, etc., which can adapt to special structures and spaces within the device and improve adaptability; with the front and back markings 9, it is easy to identify the front and back directions of the plug hard plate 2 and the connector 3 when plugging, avoiding plugging in the wrong way.
