Description

Technical Field

[0001] This utility model relates to the field of cable connector technology, specifically a PROFIBUS bus cable intermediate connector device. Background Technology

[0002] PROFIBUS bus cables play a crucial role in automation control communication. However, during use, PROFIBUS bus cables crossing active areas are frequently damaged. Currently, there are no specialized connectors available on the market, and due to the high requirements for interference resistance and transmission rate of this cable, specifications prohibit direct splicing. Therefore, when a PROFIBUS bus cable is partially damaged, the entire cable is replaced, resulting in significant waste.

[0003] For example, the PROFIBUS cable for a cold rolling mill rewinding machine, from the power distribution room substation to the rewinding machine encoder, needs to pass through a 48-meter cable tray, six cable wells, and a 12-meter-long "tank line" (a section of cable used for cable management). The 12-meter section of PROFIBUS cable passing through the "tank line" has an extremely high damage rate, requiring replacement on average every three weeks. Replacement is difficult; each replacement requires replacing 68 meters (of total length), resulting in significant waste of PROFIBUS cable.

[0004] For example, in the blast furnace pulverized coal injection area, the PROFIBUS bus cable of the overhead crane runs 92 meters from the field power distribution room to the crane. It needs to pass through a 35-meter cable trench, a 42-meter cable tray, and a 15-meter overhead crane cable chain. The 15-meter PROFIBUS cable in the overhead crane cable chain area needs to be replaced on average once a month. The replacement is difficult; each time, 92 meters (total length) need to be replaced, resulting in serious waste of PROFIBUS cable.

[0005] In the field of PROFIBUS bus cable connection, to solve the problem of wasted PROFIBUS bus cable connections, a special intermediate connector device for PROFIBUS cables is proposed. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a PROFIBUS bus cable intermediate connector device, including a lower sealing box, and further including an upper sealing box rotatably mounted on the surface of the lower sealing box. Both sides of the surface of the upper sealing box are threaded with housing screws. Both sides of the surface of the lower sealing box are provided with screw holes that mate with the housing screws. A cable shielding connection groove is fixed inside the lower sealing box. Both sides of the surface of the cable shielding connection groove are fixed with screw-type junction boxes. The screw-type junction boxes are entirely made of insulating material. Both sides of the surface of the screw-type junction boxes are provided with wire passages. Two ribbon cables are connected to the surfaces of the two screw-type junction boxes. The inner cavity of the ribbon cables contains wire bodies, and the wire bodies on both sides are connected to the wire passages on both sides.

[0008] Preferably, the ribbon cable is made of insulating material, and the wire body is made of copper conductive material with a diameter of not less than 1.5 mm².

[0009] Preferably, the surface of the lower sealing box is provided with a device sealing gasket, and the device sealing gasket is also provided on the surface of the upper sealing box.

[0010] Preferably, both sides of the screw-type junction box surface are engaged with twisted pair screws, and the other end of the twisted pair screw extends through to the surface of the wire insertion port.

[0011] Preferably, shielding wire fixing posts are fixed on both sides of the surface of the cable shielding connection groove, and the shielding wire fixing posts are protruding.

[0012] Preferably, a plurality of bus cable protection layer fixing posts are fixed on both sides of the surface of the lower sealing box. The bus cable protection layer fixing posts are conical and have a height of 1-1.5mm.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes a reliable cable connector connection method, solving the difficulty of PROFIBUS bus cable misconnection and addressing the issue of having to replace the entire PROFIBUS bus cable due to partial PROFIBUS cable damage in complex environments. It significantly increases the difficulty of replacing PROFIBUS bus cables in specific areas, greatly reduces PROFIBUS bus cable waste, and ensures the reliability and stability of the automated communication system. This tool is easy to use, compact, flexible, and offers a high level of protection, making it suitable for any production environment and potentially gaining wider application within the industry.

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] Please see Figure 1-4 As shown, a PROFIBUS bus cable intermediate connector device includes a lower sealing box 1, an upper sealing box 2 rotatably mounted on the surface of the lower sealing box 1, and housing screws 3 threadedly connected to both sides of the surface of the upper sealing box 2. Screw holes 4, which mate with the housing screws 3, are provided on both sides of the surface of the lower sealing box 1. A cable shielding connection groove 6 is fixed inside the lower sealing box 1. The cable shielding connection groove 6 is made of a good conductive metallic material. The contact length between the PROFIBUS cable shielding layer and the cable shielding connection groove 6 is greater than 7.5 mm, and the width is greater than 1 / 2 the outer diameter of the shielding layer. Both sides of the surface of the shielded connection groove 6 are fixed with screw-type junction boxes 7. The screw-type junction boxes 7 are made of insulating material. Both sides of the surface of the screw-type junction boxes 7 are provided with wire-passing ports 8. The diameter of the wire-passing ports 8 is 2mm. The surfaces of the two screw-type junction boxes 7 are connected to two ribbon cables 10. The ribbon cables 10 are made of insulating material. The inner cavity of the ribbon cable 10 is provided with a wire body 11. The wire body 11 is made of copper conductive material with a diameter of not less than 1.5mm² to ensure good conductivity on both sides. In order to facilitate the identification of the wiring, the two ribbon cables 10 are set with different colors. The wire bodies 11 on both sides are connected to the wire-passing ports 8 on both sides.

[0022] A device sealing gasket 5 is provided on the surface of the lower sealing box 1, and the device sealing gasket 5 is also provided on the surface of the upper sealing box 2. In this embodiment, the device sealing gasket 5 enables the device to be used outdoors, providing waterproof and dustproof functions, thereby improving the practicality of the device.

[0023] Both sides of the screw-type junction box 7 are engaged with twisted pair screws 9, and the other end of the twisted pair screw 9 extends through to the surface of the wire through hole 8. In this embodiment, the twisted pair screws 9 can fix the wire end and ensure reliability.

[0024] Both sides of the surface of the cable shielding connection groove 6 are fixed with shielding wire fixing posts 12. The shielding wire fixing posts 12 are raised. In this embodiment, the setting of the shielding wire fixing posts 12 can stabilize the contact between the PROFIBUS bus cable and the cable shielding connection groove 6.

[0025] Several bus cable protection layer fixing posts 13 are fixed on both sides of the surface of the lower sealing box 1. The bus cable protection layer fixing posts 13 are conical and have a height of 1-1.5mm. In this embodiment, by setting the bus cable protection layer fixing posts 13, the conical tip can penetrate the outer sheath of the PROFIBUS bus cable and firmly fix the PROFIBUS bus cable.

[0026] Working principle: The insulation layer of the two PROFIBUS bus cables to be connected is stripped with a wire stripper. The green and red wires are inserted into the screw-type junction box 7 and passed through the wire insertion port 8 to connect the cable and the wire body 11. The green and red wires are then firmly screwed into the junction box with twisted pair screws 9. The cable shielding layer must make good contact with the metal in the cable shielding connection groove 6.

[0027] In use, the cable threading port 8 and the cable body 11 connect two PROFIBUS bus cables, which allows the twisted pair and shielded wire to be reliably connected inside the protective connection device, ensuring the anti-interference and high transmission rate of the PROFIBUS bus cable. This effectively solves the problem that PROFIBUS bus cables cannot be directly connected, thus effectively solving the problem of cable waste.

[0028] The contact between the outer insulation layer of the PROFIBUS bus cable and the cable shielding connection groove 6 needs to ensure that the radius of the outer insulation layer of the cable is the same as the inner diameter radius of the outer opening of the cable shielding connection groove 6. In practical applications, it should be able to withstand a certain amount of tension to prevent it from falling off, while ensuring that the cable insulation layer has good contact with the cable shielding connection groove 6.

[0029] After the connection is completed, the lower sealing box 1 and the upper sealing box 2 can be connected by the outer casing screw 3 and screw hole 4, and the sealing gasket 5 of the device ensures the sealing performance of the device.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
