Description

Technical Field

[0001] This application belongs to the field of cable assembly technology, specifically relating to a right-angle mounting connector for mineral-insulated cables. Background Technology

[0002] In the existing technology, mineral-insulated cables play an important role in the laying of electrical lines. Due to their excellent properties such as high temperature resistance, fire resistance, and explosion resistance, they are widely used in fire protection, subway and other fields.

[0003] However, problems have gradually emerged during actual cable laying. Currently, cable trays are adjusted according to the pre-reserved locations in the building, resulting in limitations on the size and position of some trays, leading to 90-degree right-angle bends. Laying mineral-insulated cables in these bends within the trays presents significant difficulties. Forcing such bends can easily damage the cables, reducing their lifespan and safety, and potentially causing line faults. More importantly, right-angle bends cannot be directly installed, leading to frequent changes in wiring or cables not being laid as required within the trays. This severely impacts the future operation of the cables and causes considerable inconvenience to the maintenance and management of the building's electrical system.

[0004] Therefore, in order to address the challenges of laying mineral-insulated cables at right-angle bends in cable trays, there is an urgent need to develop a right-angle mounting connector for mineral-insulated cables to optimize the laying process, improve laying efficiency and safety, and ensure the stable operation of the cable system. Utility Model Content

[0005] In order to solve the technical problem in the prior art that it is difficult to install a connector to connect two cables during the laying of traditional mineral-insulated cables at a 90° bend, and that forcibly bending the cable during laying will damage the cable, significantly reduce the cable's service life and safety, and increase the probability of line faults, this application proposes a right-angle mounting connector for mineral-insulated cables.

[0006] This application adopts the following solution: a mineral-insulated cable right-angle mounting connector, including an inner right-angle connector and an insulating member disposed on the outer periphery of the inner right-angle connector. The inner right-angle connector includes a first straight tube, a second straight tube perpendicularly disposed at one end of the first straight tube, and fastening components respectively disposed at the other ends of the first straight tube and the second straight tube.

[0007] In some feasible embodiments, the fastening assembly includes fastening threads respectively disposed on the ends of the first straight pipe and the second straight pipe, a fastening nut threadedly connected to the fastening threads, and a fastening ring disposed between the fastening threads and the fastening nut. When the cable is matched and disposed in the first straight pipe / second straight pipe, the fastening ring abuts against the outer surface of the cable to fix the cable in the first straight pipe and the second straight pipe respectively.

[0008] In some feasible embodiments, the fastening ring includes a ring body and an elastic notch provided on the ring body, wherein the ring body is made of any one of brass, copper, phosphor bronze, and cupronickel.

[0009] In some feasible embodiments, the fastening nut includes a nut body, a threaded hole on the nut body, and a mounting groove in the threaded hole. When the fastening ring is matched between the fastening nut and the fastening thread, the fastening ring is matched within the mounting groove.

[0010] In some feasible embodiments, the material of the first straight tube is selected from brass, copper, phosphor bronze, and cupronickel, and the material of the first straight tube is the same as that of the second straight tube.

[0011] In some feasible embodiments, the first straight tube and the second straight tube are integrally formed.

[0012] In some feasible embodiments, the insulating element covers the outer periphery of the inner right-angle connector, and the insulating element is made of plastic.

[0013] In some feasible embodiments, the insulating element is made of any one of phenolic resin, epoxy resin, polyimide resin, polyphenylene ether resin, or unsaturated polyester resin.

[0021] Combination Figure 1-5 The following description further illustrates the technical solution proposed in this application. This application provides a mineral-insulated cable right-angle mounting connector, including an inner right-angle connector 1 and an insulating member 2 disposed on the outer periphery of the inner right-angle connector 1. The inner right-angle connector 1 includes a first straight tube 10, a second straight tube 11 perpendicularly disposed at one end of the first straight tube 10, and fastening components 12 respectively disposed at the other ends of the first straight tube 10 and the second straight tube 11. When the cable is respectively matched and disposed in the first straight tube 10 and the second straight tube 11, the fastening component 12 is used to abut against the outer surface of the cable to fix the cable in the first straight tube 10 and the second straight tube 11 respectively.

[0022] like Figure 5 As shown, in actual implementation, before connecting the cables, the cable connection ends need to be processed by removing part of the cable insulation layer to expose the conductor inside.

[0023] After pretreatment, the two cable segments are inserted into the first and second straight pipes respectively. Since the inner right-angle connector 1 is made of brass, when the two cables are inserted into the first and second straight pipes respectively, the two cables are connected in series, realizing the connection of the cables at the right-angle bend. There is no need to bend the cables, which effectively ensures the service life of the cables and avoids the occurrence of damage due to excessive bending.

[0024] This application provides a right-angle mounting connector for mineral-insulated cables, comprising an inner right-angle connector and an insulating component disposed on the outer periphery of the inner right-angle connector. The inner right-angle connector includes a first straight tube, a second straight tube perpendicularly disposed at one end of the first straight tube, and fastening components respectively disposed at the other ends of the first and second straight tubes. When cables are respectively matched and installed in the first and second straight tubes, the fastening components are used to abut against the outer surface of the cables to fix the cables in the first and second straight tubes respectively. This application achieves right-angle connection of cables through the inner right-angle connector, eliminating the need for forcibly bending the cables, effectively avoiding damage to the cables, significantly extending the service life of the cables, improving the safety and reliability of the lines, reducing the probability of line faults, and having advantages such as compact structure, convenient installation, and firm connection.

[0035] Firstly, phenolic resin has strong chemical resistance, exhibiting good tolerance to common acids, alkalis, salts, and organic solvents, and is not easily corroded by chemicals that could damage its insulation structure. In electrical equipment operating in corrosive environments such as chemical plants, it can maintain stable insulation performance, reducing equipment failures and damage caused by chemical corrosion.

[0036] Secondly, phenolic resin has excellent processing properties and can be molded using various processes, such as compression molding, lamination, injection molding, and extrusion. When producing insulating components, appropriate processing methods can be flexibly selected according to different product shapes and size requirements, achieving efficient and high-quality product manufacturing and meeting the production needs of insulating components with various complex shapes and structures.

[0037] In actual implementation, the insulating components are encapsulated on the inner right-angle connector through injection molding.

[0038] In actual implementation, the insulating component adopts a split design, which includes a first insulating part covering the outer periphery of the first straight tube, a second insulating part covering the outer periphery of the second straight tube, and a snap-fit ​​connection part disposed between the first insulating part and the second insulating part.
