[0028] The utility model provides Figure 1-5 The high-strength and easy-to-connect conductive copper busbar with a pop-up sealing structure shown comprises a conductive copper busbar body 1;

[0029] The insulating sleeve 2 is sleeved on the outside of the conductive copper busbar body 1 to protect the conductive copper busbar body 1. A fixing block 6 is fixedly connected to one side of the conductive copper busbar body 1. The two side surfaces of the fixing block 6 are provided with limiting grooves 7. A connecting piece 9 is movably provided on the outside of the fixing block 6. The inner surface of the connecting piece 9 is provided with a mounting groove 10.

[0030] A sealing mechanism 8 is arranged inside the fixing block 6 to improve the sealing performance;

[0031] The connecting assembly 11 is arranged on both sides inside the connecting piece 9 and is used for connecting the conductive copper busbar body 1. The fixing block 6 at one end of the conductive copper busbar body 1 is inserted into the mounting groove 10 in the connecting piece 9. During the insertion process, the extrusion block 802 on one side of the fixing block 6 is squeezed. Then, the extrusion block 802 pushes the internal telescopic rod 801. During the telescopic process of the telescopic rod 801, the first protrusions 803 arranged above and below squeeze the second protrusions 808 under the two groups of connecting blocks 807. The two collide with each other to push the connecting block 807 and the sealing gasket 809 to pop out from the fixing block 6, thereby sealing the connection.

[0032] like Figure 1 and Figure 3 As shown, an insulating layer 3 is provided on the surface of the conductive copper busbar body 1, a high-strength pressure-resistant layer 4 is provided below the insulating layer 3, and a high-temperature resistant layer 5 is provided below the high-strength pressure-resistant layer 4. The overall strength of the conductive copper busbar body 1 is improved by the insulating layer 3, the high-strength pressure-resistant layer 4 and the high-temperature resistant layer 5.

[0033] like Figure 3As shown, the insulating layer 3, the high-strength pressure-resistant layer 4 and the high-temperature resistant layer 5 are respectively arranged on the upper and lower sides of the conductive copper busbar body 1, the insulating layer 3 is made of polyimide, the high-strength pressure-resistant layer 4 is made of polyethylene fiber, and the high-temperature resistant layer 5 is made of polyphenylene sulfide. The high-strength pressure-resistant layer 4 is made of polyethylene fiber, which has high strength, low elongation at break, and strong energy absorption ability, while the high-temperature resistant layer 5 is made of polyphenylene sulfide, which has the characteristics of high temperature resistance, corrosion resistance, radiation resistance, and flame retardancy.

[0034] like Figure 1 , Figure 2 and Figure 4 As shown, the sealing mechanism 8 includes a telescopic rod 801, an extrusion block 802, a first protrusion 803, a limiting sleeve 804, a first spring 805, a slide groove 806, a connecting block 807, a second protrusion 808, and a sealing pad 809. The telescopic rod 801 is arranged inside the fixed block 6, and the extrusion block 802 is fixedly installed at one end of the telescopic rod 801. The first protrusion 803 is fixedly installed on both sides of the upper side of the telescopic rod 801. A limiting sleeve 804 is arranged on one side of the inner side of the fixed block 6. The inner side of the limiting sleeve 804 A first spring 805 is provided, and a connecting block 807 is movably connected to the upper and lower sides of the fixed block 6. Second protrusions 808 are fixedly installed on both sides below the connecting block 807, and a sealing gasket 809 is pasted on the top of the connecting block 807. During the extension and retraction of the telescopic rod 801 in the fixed block 6, the first protrusions 803 provided above and below are used to squeeze the second protrusion 808 below the connecting block 807, so that the connecting block 807 and the sealing gasket 809 can be popped out of the fixed block 6, thereby forming a sealing effect.

[0035] like Figure 4 As shown, both side surfaces of the interior of the fixed block 6 are provided with slide grooves 806, and the connecting block 807 is connected to the fixed block 6 through the slide grooves 806 to limit the sliding connection. When the fixed block 6 pops out, the slide grooves 806 on both sides of the interior of the fixed block 6 are used to ensure stability during movement.

[0036] like Figure 1 and Figure 5 As shown, the connecting component 11 includes an insert rod 1101, a fixed sleeve block 1102, and a second spring 1103. The insert rod 1101 is arranged on both sides of the inside of the connecting member 9, and the fixed sleeve block 1102 is fixedly installed on one side of the outside of the insert rod 1101. The second spring 1103 is arranged on the outside of the insert rod 1101. The insert rod 1101 inside the connecting member 9 is limitedly connected with the limiting grooves 7 on both sides of the fixing block 6. The fixing block 6 at one end of the conductive copper busbar body 1 is inserted into the connecting member 9 inside the connecting member 9, and then the insert rods 1101 on both sides of the connecting member 9 are pulled to retract and retract. The second spring 1103 outside the insert rod 1101 has a rebound effect, thereby pushing the insert rod 1101 to rebound and insert into the limiting grooves 7 on both sides of the fixing block 6 for limited fixing. Compared with the traditional threaded method, it is more convenient and quicker.

[0037] The working principle of the utility model is as follows: first, the insulating sleeve 2 is put on the conductive copper busbar body 1 to play a protective role, and then the fixing block 6 at one end of the conductive copper busbar body 1 is inserted into the installation groove 10 in the connecting piece 9, and then the insertion rods 1101 on both sides of the connecting piece 9 are pulled. When the fixing block 6 is inserted to the bottom of the connecting piece 9, the insertion rod 1101 is released and the second spring 1103 outside has a rebound effect, thereby pushing the insertion rod 1101 to rebound and insert into the limiting grooves 7 on both sides of the fixing block 6 for limiting and fixing. This method is convenient for connection. At the same time, when the fixing block 6 is inserted into the connecting piece 9, the extrusion block 802 on one side of the fixing block 6 will be squeezed, and then the extrusion block 802 pushes the internal telescopic rod 801 During the process of squeezing and stretching, the first protrusions 803 arranged above and below the telescopic rod 801 squeeze the second protrusions 808 under the two groups of connecting blocks 807. The two collide with each other to push the connecting blocks 807 and the sealing gaskets 809 to pop out from the fixed block 6, thereby sealing the connection. The high-strength pressure-resistant layer 4 arranged inside the conductive copper busbar body 1 has high strength, low elongation at break, and strong energy absorption ability, and the high-temperature resistant layer 5 is made of polyphenylene sulfide and has the characteristics of high temperature resistance, corrosion resistance, radiation resistance, and flame retardancy, thereby enhancing the high strength of the overall conductive copper busbar body 1. In this way, the use process of the high-strength and easy-to-connect conductive copper busbar with a pop-up sealing structure is completed.

[0038] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
