However, the above-mentioned existing technologies all set the structure of the fixed connecting piece on the outside of the insulation board, squeeze the insulation board from both sides to fix the connecting piece. In this fixing method, the insulation board will be subjected to extrusion force other than the wall, which is easy to affect the structural strength of the insulation system.

[0003] Therefore, how to reduce the extrusion force on the insulation board and improve the structural strength of the insulation system is a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

The thermal break connector is integrated with the insulation board by placing a thermal break structure made of insulation material inside the insulation board and connecting two connectors extending in opposite directions to the thermal break structure respectively. Compared with the prior art method of fixing the connector outside the insulation board, the utility model does not exert additional force on the insulation board, and can improve the structural strength of the insulation system.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The utility model provides a thermal break connector, comprising a thermal break structure made of a heat-insulating material, the thermal break structure is located inside a heat-insulating board, and the thermal break structure is respectively connected to two connectors extending in opposite directions;

Compared with the method of applying extrusion force on both sides of the outside of the insulation board to fix the connecting piece in the prior art, the method of fixing the connecting piece in the utility model does not apply additional force to the insulation board, thereby improving the structural strength of the insulation system.

[0018] 2. In the prior art, the structure of fixing the connecting parts is placed on both sides of the outside of the insulation board.

[0025] 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.

[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figures 1 to 4 As shown, the utility model provides a thermal break connector, including a thermal break structure made of a heat-insulating material, the thermal break structure is located inside the insulation board, and the thermal break structure is respectively connected to two connectors extending in opposite directions.

[0028] As the first embodiment of the utility model, the thermal break structure includes a fixed plate 1 made of a heat-insulating material, and connecting members 2 are respectively provided on opposite sides of the fixed plate 1; the heat conducted through the two connecting members 2 is interrupted at the fixed plate 1, which has the effect of blocking heat transfer. There are many ways to connect the connecting member 2 to the fixing plate 1, such as directly gluing the connecting member 2 to the fixing plate 1, or connecting the connecting member 2 to the fixing plate 1 in a detachable manner. Specifically, a mounting seat 3 is provided on the fixing plate 1, and a mounting hole 4 compatible with the connecting member 2 is provided inside the mounting seat 3. The connecting member 2 is threadedly connected to the mounting hole 4. The threaded connection may be in the form of directly providing an internal thread connected to the connecting member 2 inside the mounting hole 4, or providing a nut 5 in the mounting hole 4, the nut 5 is fixedly connected to the inner wall of the mounting hole 4, and the connecting member 2 is threadedly connected to the nut 5; the fixing plate 1 as a heat insulating component may be made of acid- and alkali-resistant plastic, nylon, concrete, etc. The preferred material of the fixing plate 1 of the utility model is plastic. Since the two connecting members 2 are insulated by the fixing plate 1, there is no restriction on the material of the mounting seat 3, which may be plastic or metal. As a preferred embodiment of the utility model, the mounting seat 3 is a tubular structure made of metal material, and the connecting member 2 is radially limited by the tubular structure.

[0029] As a second embodiment of the utility model, the broken bridge structure includes two mounting seats 3, which are respectively located on opposite sides of the fixing plate 1, and each mounting seat 3 is provided with a mounting through hole 6 adapted to the connecting member 2. The fixing plate 1 is provided with a second through hole 7 coaxial with the mounting through hole 6, and the inner diameter of the second through hole 7 is not less than the inner diameter of the mounting through hole 6. The connecting member 2 passing through the mounting through hole 6 and the second through hole 7 in sequence is connected to the mounting seat 3 located on the other side of the fixing plate 1, and the connecting member 2 is in contact with the mounting through hole 6 through the heat insulating member; when there is a gap between the connecting member 2 and the fixing plate 1, the heat insulating member can be made of a heat insulating material The heat conducted by the connector 2 is interrupted at the connection between the connector 2 and the mounting seat 3, which has the effect of blocking heat transfer. At this time, the connector 2 and the mounting seat 3 are connected together by bonding. The mounting seat 3 can also be made of metal material. At this time, the heat insulation component is a heat insulation gasket located between the mounting through hole 6 and the connector 2 or a heat insulation filler filled between the mounting through hole 6 and the connector 2. The heat conducted by the connector 2 on one side is interrupted at the contact portion between the mounting through hole 6 and the connector 2 on the other side, which can also block the heat transfer. At this time, the connector 2 and the mounting seat 3 are connected together by welding. When the connector 2 and the fixing plate 1 are in contact with each other, the heat insulation component includes not only the mounting seat 3 made of heat insulation material, or the heat insulation gasket filled between the mounting through hole 6 and the connector 2 or the heat insulation filler filled between the mounting through hole 6 and the connector 2, but also the fixing plate 1 made of heat insulation material, so that the heat on one connector 2 will not be transferred to the other connector 2 through the fixing plate 1, thereby achieving the effect of blocking the heat transfer between the two connectors 2. Similar to the first embodiment, the mounting seat 3 is also a tubular structure. The heat insulating material can be acid- and alkali-resistant plastic or nylon.

[0030] When in use, first assemble the thermal break connector 2, then place the thermal break connector 2 in the molding mold of the insulation board, and pre-embed the thermal break connector 2 in the insulation board. The fixed plate 1 is provided with a plurality of through holes 8, and the material of the insulation board is filled into the through holes 8 during molding, so that the insulation board and the thermal break connector 2 are integrated into one, thereby improving the connection firmness between the thermal break connector 2 and the insulation board; the maximum distance between the two mounting seats 3 is set to be no greater than the thickness of the insulation board, so that the part of the thermal break connector 2 except the connector 2 is completely buried inside the insulation board, further improving the connection firmness between the thermal break connector 2 and the insulation board. In addition, the mounting seats 3 located on both sides of the fixed plate 1 have the same structure, which reduces the types of components constituting the thermal break connector 2 and reduces the production cost.

[0031] It should be noted that, for those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
