[0033] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0034] Reference Figure 1 The solar thermal collector in one embodiment of the present invention is a large area thermal collector, comprising a plurality of thermal collection modules 100. Figure 2-Figure 4 as well as Figure 9-10 As shown, the solar collector module 100 is surrounded by straight frame profiles 200, and a pressure strip 300 is pressed on the frame profile 200. The frame profile 200 is preferably an aluminum profile. A groove 210 is provided on the frame profile 200. The connection points of the frame profiles 200 of the solar collector module 100 are connected by a connector 400. Specifically, the connector 400 includes a first connector 410 and a second connector 420. The first connector 410 is used to connect the frame profiles 200 between adjacent solar collector modules 100, that is, to connect three frame profiles 200. The second connector 420 is used to connect the frame profiles 200 on the corners of the solar collector modules 100 at both ends, that is, it is provided at the corners of the solar collector module 100 to connect the two outer frame profiles 200. The connector 400 comprises a connecting body and a plug-in portion. The plug-in portion is inserted into the groove 210 of the frame profile 200 and fixed thereto. The pressure strip 300 is pressed onto the frame profile 200 and secured to the upper surface of the plug-in portion by adhesive. The adhesive is preferably polyester adhesive to ensure a tight seal between the connector 400 and the pressure strip 300, preventing rainwater from entering the collector.

[0035] The above-mentioned solar collector is convenient for assembly and disassembly by arranging connectors 400 at the connection points of each frame profile 200, and is plugged into the frame profile 200 by the connector 400, and is convenient for later inspection and maintenance; at the same time, by applying glue putty between the connector 400 and the pressure strip 300, the pressure strip 300 and the glass will not be damaged during disassembly, and the sealing is good, with good waterproof performance.

[0036] Furthermore, the bead 300 is secured to the frame profile 200 via screws 500. The screws 500 secure the bead 300 by assembling and removing the frame profile 200 without damaging the connector 400, facilitating disassembly and facilitating subsequent inspection and maintenance. The inner wall of the recess 210 is threaded, and the screws 500 engage with the threads within the recess 210. Multiple screws 500 can be installed on the frame profile 200 to secure the bead 300 to the frame profile 200.

[0037] like Figure 5 and Figure 6 As shown, specifically, the first connecting member 410 includes a first connecting body 411 and three first plug-in parts 412. The three first plug-in parts 412 are respectively arranged at both ends and the middle of the first connecting body 411, and are respectively plugged and fixed with the frame profiles 200 arranged on the solar collection modules 100 on both sides and the common frame profile 200 in the middle.

[0038] The first connecting body 411 includes a first top plate 4111 and a first side plate 4112, which are arranged vertically. The first plug-in portion 412 is connected to the bottom surface of the first top plate 4111 and extends beyond the first top plate 4111 for connection to the pressure strip 300. The first top plate 4111 is positioned within a rectangular gap formed between the three frame profiles, with its side surface tightly butted against the pressure strip to which it is connected to ensure a tight seal.

[0039] The first plug-in portion 412, located at both ends of the first connecting body 411, includes a first central insert 4121 and a first short side plate 4122 disposed on one side thereof. First slots are formed between the first central insert 4121 and the first side plate 4112 of the first connecting body 411, and between the first central insert 4121 and the first short side plate 4122, respectively. The first central insert 4121 is inserted into the groove 210 of the frame profile 200 for securement. The side walls of the groove 210 are inserted into the first slots on either side for securement. The provision of the first short side plates further enhances connection stability. In other embodiments, the first short side plates may be omitted.

[0040] The first plug-in portion 412, located in the center of the first connecting body 411, includes a first central insert 4121 and first short side panels 4122 located on either side. A first slot is formed between the first central insert 4121 and the first short side panels 4122 on either side. The first central insert 4121 is inserted into the groove 210 of the frame profile 200 and secured thereto. The sidewalls of the groove 210 are inserted into the first slots on either side and secured thereto. The first short side panels 4122 located in the center can be connected to the first short side panels 4122 located on either side, forming a 90° bend.

[0041] like Figure 7 and Figure 8 As shown, the second connector 420 has a similar structure to the first connector 410, specifically comprising a second connector body 421 and two second plug-in sections 422. The two second plug-in sections 422 are vertically arranged and are respectively plugged into and fixed to the frame profile 200 at the corners of the solar collector module 100 at both ends. The second connector body 421 includes a second top plate 4211 and two second side plates 4212, which are arranged vertically in pairs. The two second plug-in sections 422 are connected to the bottom surface of the second top plate 4211 and extend beyond the second top plate 4211 for connection to the pressure strip 300.

[0042] The second plug-in portion 422 includes a second central insert plate 4221 and a second short side plate 4222 disposed on one side thereof. Second slots are formed between the second central insert plate 4221 and the second side plate 4212, and between the second central insert plate 4221 and the second short side plate 4222. The second central insert plate 4221 is inserted into the groove 210 of the frame profile 200 for fixation, and the side walls of the groove 210 are inserted into the second slots on both sides for fixation.

[0043] In this embodiment, the connecting member 400 is integrally formed, preferably made of plastic, and is injection molded for ease of manufacture and low cost.

[0044] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
