[0032] As Figures 3-7As shown, adjacent busbar trunking is connected by copper busbars 3 inserted into sealing connectors 5. Each sealing connector 5 includes a protective layer 51 filled with fire-retardant sealant. The protective layer 51 is engaged with an engagement groove 571 in the middle of the outer wall of the connector frame 57 via an internal engagement strip 55. Connecting blocks 561 are provided at the corners of the sealing gasket 56, and these connecting blocks 561 are embedded in the end face of the protective layer 51. Filling the protective layer 51 with fire-retardant sealant increases the fire resistance at the connection point.

Positioning rods 53 are symmetrically fixedly connected to the two extension blocks 52 away from the center. The two sets of positioning rods 53 are inserted into positioning holes 411 opened on the two fixed blocks 41 away from the center. Simultaneously, the two sets of positioning rods 53 are engaged with the two bent ends of the two limiting springs 44 through limiting grooves 54, facilitating pre-positioning using the positioning rods 53 and enabling quick installation and fixing of the sealing connector 5. During continuous extrusion, the engagement between the limiting grooves 54 and the limiting springs 44 achieves tight locking.
