Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of floor heating, and in particular to a floor heating module connection device. Background Art
[0002] Graphene floor heating is one of the most widely used types of existing heating floor heating. It mainly transmits current to each module through conductive sheets. The greater the current, the higher the temperature. The current graphene floor heating is connected through multiple modules, mainly through the inner copper strip.
[0003] There are two ways to connect the copper strip. One is to pierce the copper strip with a piercing nail. The nail and the copper strip are in a vertical state and connected in a point shape. The other side of the piercing nail is riveted to the wire to convert the copper strip into a wire. However, the contact area is insufficient, and there is a terminal for riveting the wire at the tail of the piercing nail. After insulation treatment, the thickness increases, which is not conducive to the neatness of the plane and affects the subsequent laying of the floor.
[0004] The second method is to punch holes in the copper strip, insert disc terminals, and rivet with bull's eye nails to convert the copper strip into a wire. This will also cause the above-mentioned problems, making the modularization of graphene floor heating more difficult and inconvenient for modular installation. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Reference Figure 1-Figure 6 The utility model provides an embodiment: a floor heating module connection device, comprising: a box body 1; a volume cavity is formed inside the box body 1, and a first connecting line 2 and a second connecting line 3 are placed; the first connecting line 2 and the second connecting line 3 are docked or overlapped, and are pressed and positioned through the box body 1 to achieve electrical connection.
[0031] In this embodiment, the first connecting line 2 and the second connecting line 3 are placed on the conductive sheet 13 in the box body 1, and the first connecting line 2 and the second connecting line 3 are clamped by pressing the box body 1 down and closed, and the second connecting line 2 and the third connecting line 3 are docked or overlapped to achieve interconnection between the floor heating modules. At the same time, the second connecting line 2 and the third connecting line 3 are planarly interconnected, so that the connection thickness is smaller, ensuring a lower contact resistance at the connection, and improving the stability of the floor heating module. The material of the conductive tape 21 is aluminum tape or copper tape.
[0032] The first connecting line 2 includes a conductive tape 21 and a heating film copper tape 22. At least one conductive tape 21 is provided. The conductive tape 21 is inserted into the heating film copper tape 22 in parallel or folded in half. The conductive tape 21 includes a connecting section 211 and a transmission section 212. The transmission section 212 is located on the inner side of the heating film copper tape 22.
[0033] In this embodiment, a conductive tape 21 is provided, which is folded in half and inserted into the inner side of the heating film copper tape 22, and the inserted part serves as a transmission section 212. A distance of 10-20 mm is reserved at both ends of the conductive tape 21, and the portion which is not inserted into the inner side of the heating film copper tape 22 serves as a connecting section 211, and the length of the connecting section 211 is 10-20 mm.
[0034] The connecting section 211 is integrally connected to the transmission section 212 and is bent toward at least one side of the heating film copper strip 22 to limit the length of the transmission section 212 extending into the inner side of the heating film copper strip 22 .
[0035] In this embodiment, the transmission section 212 is a plane, and the transmission sections 212 at both ends of the first connecting line 2 are respectively bent to the two sides of the heating film copper tape 22 and fit with the end surface of the heating film copper tape 22, forming a smaller plane at the opening of the heating film copper tape 22, and a larger plane is formed on the outside of the heating film copper tape 22, replacing the existing punching nail connection method, making the thickness of the connecting line thinner, the structure of the second connecting line 3 is the same as that of the first connecting line 2, and when connecting, the smaller planes of the first connecting line 2 and the second connecting line 3 are in contact with each other, and at the same time, the plane of the lower connecting section 211 is in contact with the conductive sheet 13, so that the thickness of the connection between the first connecting line 2 and the second connecting line 3 is thinner.
[0036] The connecting sections 211 bent on both sides of the conductive tape 21 are limited by the heating film copper tape 22 to prevent the conductive tape 21 from being inserted too deep, and the structure of the first connecting line is limited twice.
[0037] In another embodiment, the first connecting line 2 and the second connecting line 3 are directly attached to each other through the connecting section 211 on the outer side of the heating film copper tape 22, and the electrical connection is achieved through surface contact, so that the contact area is larger and the current transmission is more stable.
[0038] A glue layer 221 is provided on the outer side of the heating film copper tape 22 to adhere and fix the connecting section 211. In this embodiment, the glue layer 221 is formed by dispensing glue on the outer side of the heating film copper tape 22 to adhere and fix both sides of the connecting section 211 to ensure the structural stability of the first connecting line 2.
[0039] In another embodiment, a wire tie ring 23 may be provided on the outer side of the heating film copper tape 22. The wire tie ring 23 is located at the joint between the connecting section 211 and the outer side of the heating film copper tape 22 to clamp the connecting section 211 and prevent the connecting section 211 from not being attached to the outer side of the heating film copper tape 22, thereby increasing the thickness of the connecting section 211.
[0040] The box body 1 includes an upper cover 11 and a lower cover 12 . When the first connecting wire 2 and the second connecting wire 3 are in a docking state, a conductive sheet 13 is provided inside the box body 1 . The conductive sheet 13 is located inside the upper cover 11 or the lower cover 12 .
[0041] One side of the connecting section 211 of the first connecting line 2 or the second connecting line 3 is in contact with the conductive sheet 13 .
[0042] One side of the upper cover 11 or the lower cover 12 is convex, and the other side is concave inwardly, and the conductive sheet 13 is arranged on the outer side of the convexity or the inner side of the concave
[0043] In this embodiment, the box body 1 is of split design and is made of plastic. The upper cover 11 and the lower cover 12 are connected by a lock or a block. The upper cover 11 and the lower cover 12 are both provided with a cavity for placing and compressing the first connecting line 2 and the second connecting line 3. When the connection is made, when the first connecting line 2 and the second connecting line 3 are docked, a conductive sheet 13 is placed on the inner bottom of the lower cover 12. The length of the conductive sheet 13 is slightly larger than the length of the inner cavity of the lower cover 12, so that the conductive sheet 13 forms an arc surface that bulges upward. When the connection is made, one side of the first connecting line 2 or the second connecting line 3 contacts the conductive sheet 13, and can fit tightly with the first connecting line 2 and the second connecting line 3. Since the planar connection state is always maintained, the thickness is extremely low, which also provides great convenience for the development of the box body 1 or similar plastic clips.
[0044] Reference Figure 6 In another embodiment, one side of the upper cover 11 or the lower cover 12 is convex and the other side is concave inward. Preferably, the lower cover 12 is concave inward, and the upper cover 11 forms a convexity downward, the convexity is matched with the concaveity, and the conductive sheet 13 is arranged on the side wall of the convexity or concave. When connecting, the first connecting line 2 and the second connecting line 3 are bent after being squeezed, and the outer connecting section 211 contacts the conductive sheet 13 to achieve electrical connection.
[0045] When the first connecting wire 2 and the second connecting wire 3 are overlapped, no conductive sheet 13 is provided inside the box body 1, and electrical connection is achieved by overlapping the connecting sections of the first connecting wire 2 and the second connecting wire 3.
[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
