A high current-carrying insulated bus terminal

Abstract

The utility model relates to the technical field of insulated busbar terminals, and discloses a high-current-carrying insulated busbar terminal. The utility model includes a terminal seat with a stepped hole, and an integrated rear plug and front plug. An annular clamping ring is provided at the tail end of the front plug, and a telescopic locking end is provided on the side of the terminal seat through a spring, and a pull rod for plugging and pulling out the locking end is fixed at the tail end of the locking end. After the front plug is inserted into the terminal seat, the locking end moves and is stuck in the clamping ring to limit the movement of the front plug. The utility model is easy to install, and the connection can be achieved by plugging and installing. The gap after installation is eliminated by the deformation of the compensation gasket, which effectively avoids the situation of front and rear movement, thereby avoiding poor contact, and after pulling out the locking end, the front plug is pushed out under the action of the retreat spring, avoiding the phenomenon of breakage caused by pulling the wire.

Description

Technical Field

[0001] The utility model relates to the technical field of insulating busbar terminals, in particular to a high-current-carrying insulating busbar terminal. Background Art

[0002] Insulated terminals are electrical components used to connect circuits in electrical equipment. The main function of insulated terminals is to transmit electrical signals and conduct current. Insulated terminals can make the arrangement and connection of integrated circuit harnesses of electrical equipment more beautiful and orderly, and more convenient for maintenance, inspection and replacement.

[0003] At present, common insulated terminals usually consist of an insulating base, a number of conductive sheets arranged in a straight line on the base, and a number of bolts that cooperate with the conductive sheets to clamp the wire harness. The wire harness is fixed by bolt clamping, and its disassembly and assembly process requires the help of other tools, which is relatively complicated to operate and has low work efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to overcome the above problems, a high current-carrying insulated bus terminal is provided, which solves the above problems.

[0005] The utility model solves the technical problem by adopting the following technical solutions:

[0006] A high current-carrying insulated busbar terminal comprises a terminal seat with a stepped hole, and an integrated rear plug and front plug, wherein an annular clamping ring is provided at the rear end of the front plug, a retractable locking end is provided on the side of the terminal seat through a spring, and a pull rod for plugging and unplugging the locking end is fixedly provided at the rear end of the locking end, and when the front plug is inserted into the terminal seat, the locking end is actuated and clamped in the clamping ring to limit the movement of the front plug.

[0007] Preferably, a compensation gasket is embedded and fixed on the step surface of the inner hole of the terminal seat, and the compensation gasket is abutted against the front end surface of the rear plug to eliminate the gap between the rear plug and the terminal seat, thereby effectively improving the stability of the connection between the rear plug and the terminal seat and reducing the incidence of poor contact.

[0008] Preferably, a retreat spring is embedded and fixed in the terminal seat, and the retreat spring abuts against the front end surface of the front plug, so that when the pull rod is pulled out, the front plug is automatically pushed outward under the action of the retreat spring.

[0009] Preferably, the front plug and the inner hole of the terminal seat are clearance-fitted.

[0010] Preferably, the rear plug and the outer hole of the terminal seat are clearance-fitted.

[0011] Preferably, the engagement depth between the locking end and the snap ring is not less than one millimeter.

[0012] The advantages and positive effects of the utility model are: easy installation, connection can be achieved through plug-in, and the gap after installation is eliminated through the deformation of the compensation gasket, which effectively avoids the situation of front and rear movement, thereby avoiding poor contact, and after pulling out the locking end, the front plug is pushed out under the action of the retreat spring, avoiding the phenomenon of breakage caused by pulling the wire.
