Technical Field

[0001] This utility model relates to the field of busbar connector technology, specifically to a fireproof plug-in busbar connector structure. Background Technology

[0002] As is well known, busbar connectors are the core components of a busbar system, used to connect two busbar units to ensure electrical continuity and mechanical stability. Their performance directly affects the current-carrying capacity, temperature rise, safety, and service life of the busbar system.

[0003] A utility model patent with patent authorization announcement number CN200959506Y discloses a busbar trunking connection device for sealing the joint of two busbar trunkings that are electrically connected. The busbar trunking connection device includes a pair of connecting cover plates and a pair of connecting side plates. The pair of connecting cover plates and the pair of connecting side plates are symmetrically arranged on the four corresponding sides of the busbar trunking and seal the joint of the two busbar trunkings. The two ends of the connecting side plates are recessed inward to form a snap-fit ​​groove. At least one snap hook is installed in each snap-fit ​​groove. One end of the snap hook is slidably installed in the snap-fit ​​groove, and the other end of the snap hook extends toward the side of the busbar trunking where the connecting side plate is located and forms a fixing end for fixing the connecting side plate to the corresponding busbar trunking.

[0004] However, existing busbar connectors also have certain drawbacks. Most existing busbar connectors use bolts to assemble and fix the connector to the busbar, and the use of bolts requires professional assembly tools, which is undoubtedly inconvenient to use. Utility Model Content

[0005] The purpose of this utility model is to provide a fireproof plug-in busbar trunking connector structure, which solves the problem that existing busbar trunking connectors mostly use bolt connections to assemble and fix the connector to the busbar trunking. The use of bolts requires professional assembly tools, which makes them inconvenient to use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fireproof plug-in busbar trunking connector structure, comprising a busbar trunking body, a connector body contacting the left end of the busbar trunking body, a plug rod fixedly connected to the right end of the connector body, the plug rod being slidably connected to the busbar trunking body, a plug plate slidably connected to the inner wall of the busbar trunking body, the plug plate being slidably connected to the plug rod, an end plate fixedly connected to the end face of the plug plate, a spring being provided on the outer side of the plug plate, and a fireproof clamping mechanism being provided on the connector body.

A screw cylinder is fixedly connected to the end face of the fixing plate. The screw cylinder is slidably connected to the connector body. A fixing frame is fixedly connected to the end face of the connector body. A screw rod is installed on the vertical part of the fixing frame through a bearing. The screw rod and the screw cylinder are connected by a thread. Through the action of the screw rod, screw cylinder, and other structures, the fireproof clips can be moved for use, thereby clamping and fixing the busbar.

[0010] Preferably, the fireproof clip is rectangular in shape and made of ceramic material. The use of ceramic material ensures good fire resistance of the fireproof clip.

[0011] Preferably, an end ball is fixedly connected to the end face of the screw. The end ball is made of silicone. The end ball facilitates the rotation of the screw, and the silicone material provides a good feel when used.

[0012] Preferably, a guide plate is fixedly connected to the end face of the fixed disk, and the guide plate is slidably connected to the connector body. The fixed disk can be moved and guided by the guide plate.

[0022] The specific implementation process of this utility model is as follows: In use, by pulling the end plate 5 to move away from the busbar trunking body 1, the insertion plate 4 is moved along the inner wall of the busbar trunking body 1, causing the spring 6 to deform. Then, the connector body 2 is pushed to contact the busbar trunking body 1, so that the insertion rod 3 passes through the busbar trunking body 1, the connector body 2 is quickly positioned, and the end plate 5 is released so that the spring 6 returns to its deformation, so that the insertion plate 4 is pulled through the insertion rod 3, and the insertion rod 3 is inserted and limited, so that the connector body 2 and the busbar trunking body 1 are inserted and assembled for use. By passing the busbar connected to the busbar trunking body 1 through the gap between the four fireproof clips 71, and then pushing the end ball 76 to drive the screw 75 to rotate, under the threaded connection, the screw barrel 73 is driven to move, and the fixed plate 72 is driven to slide along the surface of the fixed rod 70, thereby driving the guide plate 77 to slide along the inner wall of the connector body 2 to ensure the stable movement of the fixed plate 72. Finally, the outermost fireproof clip 71 is driven to move, clamping and squeezing the busbar to ensure the connection stability of the busbar.
