Description

Technical Field

[0001] This utility model relates to the field of connector and electric heating floor technology, and more particularly to a connector suitable for electric heating floors and an electric heating floor including the connector. Background Technology

[0002] As living standards improve, people have increasingly higher requirements for the comfort of their living environment. Electric heating flooring is gradually gaining popularity in the market due to its features such as uniform heat dissipation, energy efficiency, environmental friendliness, and easy installation.

[0003] The technology of electric heating flooring is constantly maturing. For example, the research and application of new semiconductor heating materials have enabled an electrothermal conversion rate approaching 100%, rapid and uniform self-heating, and good anti-aging properties. These technological advancements have not only improved product reliability and durability but also reduced production costs, making electric heating flooring more competitive in the market. However, current electric heating flooring uses traditional male-female sockets and plugs, which are directly installed on the heating flooring. From the installation of the heating flooring modules to the pressing, grooving, and packaging processes, each step must be strictly matched and controlled. However, improper operation in any step can still easily lead to defective products, resulting in waste and increased costs.

[0004] For example, in patents CN201520609498.1, "Low Electromagnetic Radiation Electric Heating Floor," and CN201420757466.1, "An Electric Heating Floor," the connecting sockets and plugs are both located on the electric heating floor, and the male and female parts are separated. When connecting adjacent electric heating floors, the sockets and plugs on the electric heating floor need to be directly plugged in, which is inconvenient to operate and can easily produce defective products during the production process. Summary of the Invention

[0005] In view of this, in order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide an improved connector, whose male and female plugs are integrally formed and are independent of the electric heating floor, making production, installation and maintenance convenient.

[0006] To solve the above technical problems, the technical solution adopted by this utility model is as follows:

[0007] A connector suitable for electric floor heating includes a connecting wire and connectors located at the ends of the connecting wire. Each connector includes an insulator, a wire, a connecting post, and a connecting groove. A connecting piece is disposed on the inner wall of the connecting groove. The connecting post and the connecting groove are disposed on one side of the insulator, and the wire is connected to the other side of the insulator. A conductor within the wire passes through the insulator and connects to the connecting post and / or the connecting piece. Both the connecting post and the connecting piece are conductors. One end of the connecting post is connected to the conductor within the wire, and the other end is used to connect to the connecting piece. One end of the connecting piece is connected to the conductor of the wire, and the other end is used to connect to the connecting post. The connector is integrally molded, and each connector has a male and female plug, allowing for interchangeable use.

[0008] According to some preferred embodiments of the present invention, the outer diameter of the connecting column is greater than or equal to the inner diameter of the connecting groove.

[0009] According to some preferred embodiments of the present invention, the length of the connecting post is matched with the depth of the connecting groove.

[0010] According to some preferred embodiments of the present invention, the length of the connecting piece is less than the depth of the connecting groove.

[0011] According to some preferred embodiments of this utility model, a first blocking structure is provided within the connecting groove, the first blocking structure being formed by the insulator extending inward along the circumference of the connecting groove. Preferably, the first blocking structure comprises multiple blocking rings integrally formed with the insulator.

[0012] According to some preferred embodiments of this utility model, a second blocking structure is provided at the connection between the connecting post and the insulator. The second blocking structure is formed by extending the insulator outward along the circumference of the connecting post. Preferably, the second blocking structure consists of multiple blocking rings, integrally formed with the insulator.

[0013] According to some preferred embodiments of this utility model, the first blocking structure and the second blocking structure are staggered. When the connector is inserted, the blocking rings on the first blocking structure and the blocking rings on the second blocking structure are staggered, preferably with the blocking rings on the first blocking structure and the blocking rings on the second blocking structure in close contact, to further improve the sealing effect, waterproof effect and anti-detachment effect.

[0014] The present invention also provides an electric heating floor including the connector described above.

[0015] According to some preferred embodiments of the present invention, the electric heating floor includes a top plate, a heating module and a bottom plate in sequence. The heating module includes a heating wire, a bus and a terminal. The two ends of the heating wire are connected to the bus, and the terminal is connected to the end of the bus.

[0016] According to some preferred embodiments of this utility model, a connector is connected between adjacent electric heating floors, and the connector's connector head is plugged into the terminal. The two terminals have identical structures, and are the same as the connector head, facilitating the plugging of the connector head into the terminal.

[0017] Due to the adoption of the above technical solutions, this utility model has the following advantages compared with the prior art: The connector of this utility model for electric heating floor is provided with a connecting post and a connecting groove on each connector head. It is a male and female integrated design and is independent of the electric heating floor, which facilitates production, transportation, installation, maintenance and replacement, improves the yield rate and reduces production and maintenance costs.

Many specific details are set forth in the following description to provide a full understanding of the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present utility model. Therefore, the present utility model is not limited to the specific embodiments disclosed below.

[0024] like Figure 1-3 As shown, the electric heating floor in this embodiment includes a top plate, heating modules 4, a bottom plate, and connectors 1 for connecting heating modules 4 on adjacent electric heating floors. The top plate, heating modules 4, and bottom plate are arranged sequentially. The heating module 4 includes heating wires 41, a bus 42, and terminals 43. The two ends of the heating wires 41 are connected to the bus 42, and the terminals 43 are connected to the ends of the bus 42 via wires 32. The top plate and / or the bottom plate have receiving slots for accommodating the terminals 43. Adjacent electric heating floors are connected by connectors 1, with the connector head 3 of the connector 1 inserting into the terminals 43. The two terminals 43 have identical structures and the same structure as the connector head 3, facilitating the insertion of the connector head 3 into the terminals 43.

[0025] like Figure 1-2 As shown, the connector 1 for electric heating floor in this embodiment includes a connecting wire 2 and a connector 3 located at the end of the connecting wire 2. In the original state of the connecting wire 2, the connectors 3 at both ends face opposite directions to facilitate insertion with the terminals 43 on two adjacent electric heating floors.

[0026] Each connector 3 includes an insulator 31, a wire 32, a connecting post 33, and a connecting groove 34. The end of the connecting wire 2 extends to the connector 3 to form the wire 32. A connecting piece 35 is provided circumferentially on the inner wall of the connecting groove 34. The connecting post 33 and the connecting groove 34 are located on one side of the insulator 31, and the wire 32 is connected to the other side of the insulator 31. The conductor 36 inside the wire 32 passes through the insulator 31 and connects to the connecting post 33 or the connecting piece 35; both the connecting post 33 and the connecting piece 35 are conductors 36. The connector 1 is integrally formed, and each connector 3 is provided with a male and female plug, which can be interchanged.

[0027] When connector 3 is inserted into terminal 43, one end of connector 33 is connected to conductor 36 inside wire 32, and the other end is used to connect to connector 35. One end of connector 35 is connected to conductor 36 of wire 32, and the other end is used to connect to connector 33. The outer diameter of connector 33 is equal to the inner diameter of connector groove 34; the length of connector 33 matches the depth of connector groove 34; the length of connector 35 is less than the depth of connector groove 34.

[0028] In this embodiment, a first blocking structure 37 is provided in the connecting groove 34. The first blocking structure 37 is formed by the insulator 31 extending inward along the circumference of the connecting groove 34. A second blocking structure 38 is provided at the connection between the connecting post 33 and the insulator 31. The second blocking structure 38 is formed by the insulator 31 extending outward along the circumference of the connecting post 33. Preferably, the first blocking structure 37 and the second blocking structure 38 are staggered.

[0029] Preferably, both the first blocking structure 37 and the second blocking structure 38 are provided with three blocking rings and are integrally formed with the insulator 31. Specifically, when the connector 3 is inserted into the terminal 43, the blocking rings on the first blocking structure 37 and the blocking rings on the second blocking structure 38 are staggered, that is, after the connector 3 is inserted into the terminal 43, multiple blocking rings are arranged along the axial direction of the connecting post 33, and the blocking rings on the first blocking structure 37 and the blocking rings on the second blocking structure 38 are alternately arranged. Preferably, the blocking rings on the first blocking structure 37 and the blocking rings on the second blocking structure 38 are in close contact to further improve the sealing effect, waterproof effect, and anti-detachment effect. That is, the blocking rings are used to achieve sealing, waterproofing, and anti-detachment.

[0030] The connector 1 for electric heating floors in this embodiment is a single, identical unit. Each connector head 3 is equipped with a connecting post 33 and a connecting groove 34, forming a male-female integrated design. The two connector heads 3 at both ends have completely identical structures, and the terminal 43 on the floor heating module 4 also has the same structure, facilitating production and installation. The male connector is a metal cylinder design (connecting post 33), with a tubular lower end that embeds an insulator 31 and connects to the wire 32. The mating part with the insulator 31 is provided with three layers of waterproof barriers (second barrier structure 38). The female connector (connecting groove 34) has three layers of waterproof barriers at its entrance (first barrier structure 37). The wire 32, insulator 31, and waterproof barriers are integrally formed. The connector 1 for electric heating floors in this embodiment is independent of the electric heating floor, facilitating production, transportation, installation, maintenance, and replacement. It improves the yield rate, eliminates unnecessary waste, increases on-site installation efficiency, reduces environmental pollution, and lowers production costs for enterprises and consumption costs for users.
