Description

BACKGROUND OF THE INVENTION 1. Field of the Invention

[0001] The present invention relates to a transmission cable set, and more particularly to a transmission cable set having a fool-proof structure.2. Description of the Related Art

[0002] The advent of the Internet of thing (IOT) appears, so that everything can be connected to the Internet. In other words, in addition to computers and mobile devices, many devices have the ability to connect to the Internet. However, the basic requirement for connecting to the Internet is to be able to pass signals from various devices.

[0003] At present, signals of devices such as electrical equipment, electric vehicles, electric bicycles, and mechanical control systems are transmitted, usually through transmission lines. Power lines and transmission lines are generally configured separately. Therefore, the traditional signal lines such as RS232, RS485, I2S, I2C, USB, etc. become standard usable signal lines. However, these standard transmission lines do not have the ability to transmit power. In other words, the use of these standard signal lines is necessary to transmit with a power line. In this way, it will cause a lot of problems and high cost.

[0004] In addition, in the interior of electrical equipment, electric vehicles, electric bicycles, and mechanical control systems, when additional signal lines or power lines are required, it is often required to be achieved through wiring, which makes construction difficult, and may damage equipment due to wiring errors. In addition, for water-proof and fool-proof, there are often a variety of institutionalbased designs. At present, the fool-proof and water-proof of signal line use special mechanisms such as buckles, anti-stay bumps, special design pins and so on. The water-proof design is mostly designed with a covered male and female plug. Most of these designs have a situation where mass production is not easy.

[0005] Document US2015 / 207279A1 relates to an electrical connector, and more particularly to a flippable plug connector used with a receptacle connector that forms part of the state of the art.

[0006] Therefore, to develop a transmission line set that does not have wiring errors and can be easily wired, and has a function of signal transmission or even power transmission, and is capable of being water-proof and mass-produced, becomes a an important technology development direction of signal line of the Internet era..BRIEF SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION

[0011] The present invention uses a male plug transmission cable and a female plug transmission cable, and the conductive interface of the male plug and the conductive elastic sheet of female plug are designed to be vertically symmetrical, so that the male plug and the female plug can be docked and fast-connected; and due to the design of the male plug and the female plug, the present invention can achieve special technical effects such as quick plugging, stable wiring, easy to fall off, water-proof, and easy mass production.

[0012] First, please refer to FIG. 1A to FIG. 1C , which are front, cross-sectional and perspective views of a male plug transmission cable 1 in a transmission cable set of the present invention. The male plug transmission cable 1 has a first protruding portion 13 and a second protruding portion 12 to form a male plug, and includes other components such as the above conductive interfaces 31-1, 31-2, 31-3, 31-4, the lower conductive interface 32-1, 32-2, 32-3, 32-4, the first cladding layer 11, the second cladding layer 14, the wire cladding portion 50, the wires 52, 53, and the welded portion 71 , 72, etc. The first protruding portion 13 is disposed at the center of the male plug, and the second protruding portion 12 is in a ring shape and annular. The first protruding portion 13 and the second protruding portion 12 form a third groove 15 with a ring shape. The protruding portion 13 has upper and lower surfaces, and each of the four upper conductive interfaces 31-1, 31-2, 31-3, 31-4 and each of four lower conductive interfaces 32-1, 32-2, 32-3, 32-4 are disposed. The four upper conductive interfaces 31-1, 31-2, 31-3, 31-4 and the four lower conductive interfaces 32-1, 32-2, 32-3, 32-4 are symmetrically conductive with each other at opposite angles, as shown in FIG. 3A. Thus, after the so-called upper conductive interfaces 31-1, 31-2, 31-3, and 31-4 are turned over, the order of wiring is the same as that of the lower conductive interfaces 32-1, 32-2, 32-3, and 32-4. The wiring sequence will be identical. In this way, errors caused by reverse wiring can be prevented.

[0013] Further, since the first protruding portion 13 has both upper and lower surfaces and is planar, the welded portions 71, 72 and the like are easily automated produced, and thus the mass production is facilitated.

[0014] For example, the signals represented by the four upper conductive interfaces 31-1, 31-2, 31-3, 31-4 are power supply, signal 1, signal 2 and ground, respectively; then the signals represented by four lower conductive interfaces 32-1, 32-2, 32-3, 32-4 are ground, signal 2, signal 1, and power. This is the concept that the two sides of conductive interfaces are symmetrically conductive with each other at opposite angles.

[0015] Next, please refer to FIG. 2A to FIG. 2C , which are front, cross-sectional and perspective views of the female plug transmission cable 2 in the transmission cable set of the present invention. The female plug transmission cable 2 has a third protruding portion 22 and a fourth protruding portion 21 to form a female plug, and includes other components such as the conductive elastic sheets 41-1, 41-2, 41-3 and 41-4, the lower conductive elastic sheets 42-1, 42-2, 42-3 and 42-4, the third cladding layer 24, the wire covering portion 60, the wires 62, 63, and the welded portions 81, 82, the elastic sheet column 23 and so on. The third protruding portion 22 is formed in a ring shape and annular to form a first groove 26, and the first groove 26 is located at the center of the female plug. The fourth protruding portion 21 is formed in a ring shape and annular, and a second groove 25 is formed between the fourth protruding portion 21 and the third protruding portion 22. The inner surface of the third protruding portion 21 has upper and lower inner surfaces, each disposes the four upper conductive elastic sheets 41-1, 41-2, 41-3, 41-4 and at least two lower conductive elastic sheets 42-1, 42-2, 42-3, 42-4. The four upper conductive elastic sheets 41-1, 41-2, 41-3, 41-4 and the four lower conductive elastic sheets 42-1, 42-2, 42-3, 42-4 are symmetrically conductive with each other at opposite angles, as shown in FIG. 3B. Thus, after the so-called upper conductive elastic sheets 41-1, 41-2, 41-3, 41-4 are turned over, the order of wiring is the same as that of the lower conductive elastic sheets 42-1, 42-2, 42-3, and 42-4. The wiring sequence will be identical. In this way, errors caused by reverse wiring can be prevented.

[0016] Further, since the inner surface of the third projecting portion 13 has upper and lower surfaces and is planar, the welded portions 81, 82 and the like are easily automated produced and the mass production is facilitated.

[0017] For example, the signals represented by the four upper conductive elastic sheets 41-1, 41-2, 41-3, and 31-4 are ground, signal 2, signal 1, and power source, respectively; then the signals represented by the four lower conductive elastic sheets 42-1, 42-2, 42-3, and 42-4 are power, signal 1, signal 2, and ground, respectively. This is the concept that the two sides of conductive interfaces are symmetrically conductive with each other at opposite angles.

[0018] The correspondence between the conductive interfaces and the conductive elastic sheets are mapped to each other (the same amount), and are organized as follows: upper conductive interface 31-1upper conductive interface 31-2upper conductive interface 31-3upper conductive interface 31-4powersignal 1signal 2groundlower conductive interface 32-1lower conductive interface 32-2lower conductive interface 32-3lower conductive interface 32-4groundsignal 2signal 1powerupper conductive elastic sheets 41-1upper conductive elastic sheets 41-2upper conductive elastic sheets 41-3upper conductive elastic sheets 41-4groundsignal 2signal 1powerlower conductivelower conductivelower conductivelower conductiveelastic sheets 42-1elastic sheets 42-1elastic sheets 42-1elastic sheets 42-1powersignal 1signal 2ground

[0019] Next, please co-referring to FIG. 1B, FIG. 2B and FIG. 4. For the male plug transmission cable 1 and the female plug transmission cable 2, the first groove 26 of the female plug transmission cable 2 can accommodate the male plug transmission cable 1. The first protruding portion 13 of the female plug transmission cable 2 can accommodate the second protruding portion 12 of the male plug transmission cable 1; in turn, the third groove 15 of the male plug transmission cable 1 can accommodate the third protruding portion 22 of the female plug transmission cable 2. Thus, the design of the male plug transmission cable 1 and the female plug transmission cable 2 form a triple clamping mechanism, so that the male plug transmission cable 1 and the female plug transmission cable 2 are combined with each other, and not easy to fall off. It is a major innovative feature for the present invention.

[0020] In addition, in the embodiment of FIG. 1B and 1C, the protruding length of the first protruding portion 13 of the male plug transmission cable 1 is shorter than the protruding length of the second protruding portion 12. Thus, it constitute a protruding section of the second protruding portion 12 and he protruding section of the first protrusion portion 13 to form a distance D1. This design protects the four upper conductive interfaces 31-1, 31-2, 31-3, 31-4 and the four lower conductive interfaces 32-1, 32-2, 32-3, 32-4 among the first protruding portion to be not easy to expose and suffer damage, and forms a high impedance condition.

[0021] In addition, the second protruding portion 12 and the third protruding portion 22 are made of a plastic material, and the fourth protruding portion 21 is made of a rubber material or a plastic material.

[0022] The above embodiment is an embodiment in which four upper conductive interfaces, four lower conductive interfaces, four upper conductive elastic sheets and four lower conductive elastic sheets are used. For other embodiments of the present invention, more than two upper conductive interfaces, lower conductive interfaces, upper conductive elastic sheets, and lower conductive elastic sheets may be combined. For example, two to be a group include a power line and a ground line. For example, three to be a group include a power line, a ground line, and a signal line. For example, two to be a group include a first signal line and a second signal line. For example, three to be a group include a first signal line, a second signal line, and a third signal line. And, it is so on and so forth.
