Description

Technical Field

[0001] The utility model relates to a data line manufacturing technology in the technical field of data transmission, in particular to a three-joint panel connecting line. Background Art

[0002] PCB double-sided boards are an important type of circuit board. They are characterized by wiring on both sides, and the wiring can be staggered. This design enables the circuit board to carry more electronic components and is more suitable for more complex circuit structures than single-sided boards to improve the integration and working efficiency of electronic equipment.

[0003] When connecting data cables on double-sided PCB boards, multiple data interfaces are often required. Therefore, traditional dual-connector cables are difficult to meet the interface connection requirements on the front and back panels. In order to solve this problem, a variety of multi-connector cables have appeared on the market, among which three-connector panel cables are popular because they can connect three interfaces at the same time, thus realizing one-to-two data transmission operations; however, the branch line setting of the existing three-connector panel cables is relatively simple, and the strength and stability of the branch line position are poor. They are prone to breakage or loosening under external force conditions or after a period of use, resulting in poor contact, unstable signal transmission and other problems, affecting the stability and efficiency of data transmission.

[0004] Therefore, it is necessary to improve the existing three-joint panel connecting wire to improve its use effect. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a three-joint panel connecting line to solve the shortcomings of the above-mentioned background technology.

[0006] The technical problem solved by the utility model is achieved by the following technical solutions:

[0007] A three-joint panel connection line, comprising a main line, one end of which is assembled and connected with a first joint, and the other end of which is divided into two branch lines, and the ends of the two branch lines are respectively assembled and connected with a second joint and a third joint;

[0008] The main line is composed of a plurality of single wires, and the single wires constituting the main line are arranged in upper and lower double rows; the two branch lines include a thick branch line with a larger number of single wires and a thin branch line with a smaller number of single wires, and the thin branch line and the thick branch line correspond to the upper row of single wires and the lower row of single wires of the main line respectively;

[0009] The thin branch lines and the upper row of single lines are integrally wrapped with a first packaging material, and the thick branch lines and the lower row of single lines are integrally wrapped with a second packaging material; the first packaging material and the second packaging material of the main line part are also wrapped with a third packaging material on the surface, and the third packaging material wraps the branching position of the entire main line and the two branch lines on the outside.

[0010] As a further limitation, the first connector, the second connector and the third connector are all phosphor copper tin-plated terminals encapsulated in a plastic shell, and the connection positions of the first connector, the second connector and the third connector and the corresponding main line and branch line are gap-sealed with UV glue.

[0011] As a further limitation, the single wire includes a conductor core and an insulating layer covering the conductor core, the thickness of the insulating layer is 0.1 mm to 0.3 mm, and the single wires in the same row and adjacent to each other are connected together by wire bonding on the outer side of the insulating layer.

[0012] As a further limitation, the number of single lines of the thick branch lines is 1 to 2 times the number of single lines of the thin branch lines.

[0013] As a further limitation, the length of the thin branch line is 30 to 70 mm, and the length of the thick branch line is 20 to 30 cm longer than that of the thin branch line.

[0014] As a further limitation, the first packaging material is one of high-density polyethylene, rubber, nylon fabric, and silica gel.

[0015] As a further limitation, the second packaging material is a combination of one of high-density polyethylene, polyethylene, and silica gel and a glass fiber tube; the third packaging material is a glass fiber tube or a nylon fabric layer;

[0016] When the thick branch line and / or the main line adopts a glass fiber tube as the packaging material, the outer end of the glass fiber tube corresponding to the joint side is wrapped with a heat shrink tube.

[0017] Beneficial effects: The three-joint panel connecting line of the utility model designs the main line into a double-row single-wire structure, and uses different numbers of single wires in the two branch lines to form a thick branch line and a thin branch line, and outsources the thin branch line, thick branch line and main line with different packaging material structures. This multi-layer packaging material design not only improves the overall mechanical strength of the connecting line, but also further improves the stability and durability of the branch line position. The branch line position can be evenly stressed, effectively avoiding breakage or loosening under the action of external force, and improving the service life and durability of the connecting line. The different outsourcing designs of the thick branch line and the thin branch line can also ensure the balance and stability of data transmission between the main line and the branch line while taking into account the cost.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figure 1 A preferred embodiment of a three-connector panel connection line, the three-connector panel connection line of this embodiment realizes the one-to-two data transmission function of the three-connector panel connection line through the layout design of the main line and the branch line, and meets the multi-interface connection requirements on the PCB double-sided board.

[0022] The three-joint panel connection line includes a main line, which includes a plurality of single lines, each of which is similar to a conventional connection line single line, and includes a conductor core and an insulating layer covering the conductor core, and the insulating layer is relatively thin, with a thickness of 0.1 mm to 0.3 mm. These single lines are distinguished according to their functions and arranged in double layers (two rows), and the single lines in the same row and adjacent to each other are connected together by wire bonding on the outer side of the insulating layer.

[0023] The main line is assembled and connected to the first joint 1 on the left side and on the right side of the first joint 1. The main line is divided into two branch lines on the right side, one of which is a thick branch line with a large number of single lines, and the other branch line is a thin branch line with a small number of single lines. The end of the thin branch line is assembled and connected to the third joint 9, and the end of the thin branch line is assembled and connected to the second joint 6.

[0024] In this embodiment, the number of single lines of the thick branch line is 1 to 2 times the number of single lines of the thin branch line. This design can ensure that the thick branch line and the thin branch line can be set with different connectors according to their actual needs, and have stronger data transmission capabilities and mechanical strength to meet different data interaction needs.

[0025] The thin branch line and the upper single line of the main line are integrally wrapped by the first wrapping material 3, while the thick branch line and the lower single line of the main line are integrally wrapped by the second wrapping material 8. The first wrapping material 3 can be made of one of high-density polyethylene, rubber, nylon fabric, silicone and the like, while the second wrapping material 8 is a combination of one of high-density polyethylene, polyethylene, silicone and the like and a glass fiber tube, and is formed in such a way that one of high-density polyethylene, polyethylene, silicone and the like is used as the inner lining, and the outer surface of the lining is wrapped with a glass fiber tube to enhance the mechanical strength and durability of the branch line.

[0026] In addition, the first packaging material 3 and the second packaging material 8 of the main line part are additionally wrapped with a third packaging material 7. The third packaging material 7 is made of glass fiber tube or nylon fabric layer. When the third packaging material 7 wraps the aforementioned wire part, the left end is located on the inner side of the first joint 1, and the right end wraps the branching position of the main line and the two branch lines, so as to improve the mechanical strength of the main line segment itself while ensuring the structural strength of the branching position, and prevent the branching position from breaking or loosening when external force is applied between the thick branch line / thin branch line.

[0027] When glass fiber tubes are used as packaging materials for thick branch lines and / or main lines, in order to further improve the structural strength of the joints, heat shrink tubes 2 are used to provide additional reinforcement and protection at the outer ends of the glass fiber tubes corresponding to the joints to ensure that the connecting lines are not easily damaged by external forces during use.

[0028] In order to improve the stability and durability of the connecting line, the first connector 1, the second connector 6 and the third connector 9 all use phosphor copper tin-plated terminals encapsulated in a plastic shell, and UV glue 5 is used to perform gap filling at the connection position with the corresponding main line and branch line. This can not only enhance the stability of the connector, but also effectively prevent moisture, dust and other impurities from entering the interior of the connector and affecting the stability of data transmission.

[0029] In terms of length design, the length of the thin branch line is set to 30-70mm to meet the needs of short-distance data transmission. The length of the thick branch line is 20-30cm longer than the thin branch line to meet the needs of longer-distance interface connection. Such a length design not only meets the needs of actual use, but also makes the layout of the entire connection line more reasonable and beautiful.

[0030] Through the above design, the three-connector panel cable of this embodiment not only has excellent data transmission performance, but also has high mechanical strength and durability. The design of its multi-layer packaging material allows the cable to be evenly stressed at the branching position, effectively avoiding breakage or loosening under the action of external force. At the same time, the design of the thick branch line and the thin branch line also takes into account the balance and stability of data transmission, so that the entire cable performs well in actual use.

[0031] To sum up, the three-connector panel connecting cable of this embodiment realizes efficient and stable data transmission function through reasonable layout design and high-quality material selection, and improves the service life and durability of the connecting cable, meeting the needs of multi-interface connection on the PCB double-sided board.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
