Abstract
The utility model discloses a sleeve type connector suitable for pin plugs with different sections, which comprises an upper tubular terminal and a lower tubular terminal, wherein an insulating sheath is fixedly sleeved outside the upper tubular terminal, a spring piece is fixedly arranged inside the upper tubular terminal, an internal thread is arranged at the bottom of the upper tubular terminal, and an external thread is arranged at the top of the lower tubular terminal. According to the sleeve type connector applicable to the pin plugs with different sections, the spring piece is arranged in the upper tubular terminal, and then when the pin plug is inserted into the upper tubular terminal, the pin plug can be in close contact with the spring piece, so that the spring piece generates certain deformation, and the pin plug is conveniently applicable to the pin plugs with different sectional areas in the aviation plug of a circuit breaker handcart switch.
Description
Technical Field
The utility model belongs to the technical field of connection of aviation plugs of circuit breakers, and particularly relates to a sleeve type connector suitable for pin type plugs with different sections.
Background
The circuit breaker is a switching device capable of closing, carrying and opening/closing a current under a normal circuit condition and a current under an abnormal circuit condition within a prescribed time, and can be used for distributing electric energy, starting an asynchronous motor infrequently, protecting a power supply line, a motor and the like, automatically cutting off a circuit when a fault such as severe overload or short circuit or undervoltage occurs, and the like, and has a function equivalent to a combination of a fuse type switch and an over-under-heat relay and the like.
At present, when the handcart switch characteristic of the circuit breaker is tested, a common instrument wire clamp is fixed on a pin type plug of a handcart aviation plug, the wire clamp is not firm and is easy to drop, double-needle-head serial connection is easy to cause, certain hidden danger also exists in the safety of testing personnel, and a sleeve type connector suitable for pin type plugs with different sections is provided for the purpose.
