Description

Technical Field

[0001] This utility model relates to the field of cable technology. Background Technology

[0002] In the field of graphene heating technology, such as underfloor heating and wall heating systems, cables for powering the heating modules are an essential component. For graphene underfloor heating systems, the most common type of cable used in the market is the spliced ​​cable, which connects each heating module in parallel through a T-shaped tee connector. This type of T-shaped tee connector and cable has a certain degree of scalability and can meet the user's custom layout needs. However, this method has the following shortcomings: (1) The wiring is cumbersome and prone to errors. When the area to be laid is small, the user can splice the cable himself, but when it is necessary to lay more... When the area is large, the cables are intertwined and there are many joints. It is very cumbersome to splice the cables segment by segment. Especially when there are both male and female plugs on a cable, users are very likely to make mistakes and directly short-circuit the live wire and the neutral wire, causing a short circuit. (2) It is difficult to hide the wires. For safety and aesthetic considerations, it is necessary to lay the heating modules and carry out reasonable wiring and wire hiding. However, the T-type three-way connector is large in size. After the connection, the main line and the branch line are distributed at a 90-degree angle, which makes it difficult to manage the wires. It is very bulky when wiring and difficult to store. It is easy to cause the heating modules to not be seamlessly spliced, which affects the aesthetics. Summary of the Invention

[0003] In view of this, the present invention provides a cable for connecting graphene heating modules, which is simple to wire, less prone to errors, and can effectively improve wiring efficiency.

[0004] A cable for connecting a graphene heating module includes a power plug, a main cable, a branch cable, a quick connector, a crimping ring, and an insulating sheath. The power plug is located at one end of the main cable and is electrically connected to the main cable. The main cable includes a main conductor and a main insulation layer. The branch cable includes a branch conductor and a branch insulation layer. One end of the branch conductor is twisted to the main conductor, and the twisted joint is crimped by the crimping ring. The other end of the branch conductor is electrically connected to the quick connector. The quick connector has a connection structure adapted to the interface of the graphene heating module. The insulating sheath is used to cover the crimped portions of the main conductor and the branch conductor.

[0005] The main insulation layer and the branch insulation layer are made of cross-linked polyethylene.

[0006] The insulating sheath is made of low-smoke, halogen-free flame-retardant material.

[0007] The connection structure is a threaded sleeve, and the quick connector and the interface of the graphene heating module are detachably connected through a matching threaded structure.

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

[0009] (1) Before leaving the factory, the length, number of branches and electrical parameters of the prefabricated cable are customized according to the user's needs and the number of heating modules, so as to realize plug-and-play installation and save the tedious process of on-site wiring and adaptation.

[0010] (2) Only one type of quick connector is provided on the branch cable. When laying the graphene heating module, it is only necessary to connect the quick connector to the interface of the heating module. The wiring is simple and convenient, which can shorten the connection time of each node and effectively improve work efficiency.

[0011] (3) The two adjacent quick connectors cannot be connected in structure to avoid the problem of accidentally connecting the live wire and the neutral wire;

[0012] (4) By covering the crimped joint with an insulating sheath, the space occupied is smaller than that of a T-type tee connector. The main cable and branch cable have the same exit angle after being covered, which can be easily stored in the cable management space reserved between each graphene heating module, providing ideal conditions for the seamless splicing of subsequent graphene heating modules.

[0017] The invention will be described in detail below with reference to specific embodiments.

[0018] See Figure 1 This embodiment provides a cable for connecting a graphene heating module, including a power plug 1, a main cable 2, a branch cable 3, a quick connector 4, a crimp ring 5, and an insulating sheath 6. The power plug 1 is located at one end of the main cable 2 and is electrically connected to the main cable 2. The power plug 1 is used to connect to a socket to provide power. See [link to relevant documentation]. Figure 2The main cable 2 includes a main conductor 21 and a main insulation layer 22, and the branch cable 3 includes a branch conductor 31 and a branch insulation layer 32. The main insulation layer 22 and the branch insulation layer 32 are made of cross-linked polyethylene. The specific parameters of the main cable 2 and the branch cable 3 (such as conductor cross-sectional area) are customized according to the specific number and power of the graphene heating modules to be laid. One end of the branch conductor 31 is twisted to the main conductor 21, and the other end is electrically connected to the quick connector 4. A crimping ring 5, for example, made of brass, is used to crimp the twisted joint using a hydraulic tool. The quick connector 4 has a connection structure adapted to the interface of the graphene heating module. The insulating sheath 6 is made of low-smoke halogen-free flame-retardant material and is used to cover the crimped part through injection molding. The connection structure of the quick connector 4 is a threaded sleeve 41, which forms a screw-fit with the thread of the graphene heating module interface. The quick connector 4 can also be a magnetic connection structure, used with neodymium iron boron permanent magnets.

[0019] The usage process of this utility model is as follows: Before leaving the factory, the cable of this utility model is produced according to the actual needs of the user. During installation, the quick connector 4 is connected to the corresponding graphene heating module interface one by one. Specifically, the threaded sleeve 41 is screwed into the thread of the graphene heating module. Then, the power plug 1 is inserted into the socket to turn on the power.
