Technical Field

The invention relates to the field of separating mechanisms, in particular to a guide rail type retractable separating mechanism.

Background

The electric separation mechanism (electric connector separation mechanism) is used for automatically unlocking and separating the electric connector when an aircraft (such as a missile or a rocket) is launched, after the aircraft on the launching device is installed in place, the mechanism can ensure that the plug and the socket of the electric connector are conveniently plugged, when the aircraft is launched, the electric separation mechanism ensures that the plug and the socket of the electric connector can be quickly unlocked and separated, and the socket and the plug of the electric connector are separated without interfering the aircraft or bringing additional load to the aircraft.

The rapidity with which the electrical disconnect mechanism separates the plug and receptacle of the electrical connector can have a large impact on aircraft launch, and slow separation speeds can result in damage to the electrical connector plug. In the prior art, an electrical separation mechanism realizes separation of a plug and a socket fixed on an aircraft by pulling a connecting rod to move around a fixed shaft through a spring, or realizes separation of the socket of an electrical connector and the plug arranged on a separator by pulling the separator to move along an inclined guide rail through the spring. Because the speed of the aircraft is very fast, the connecting rod type electric separation mechanism is separated by rotation, the separation speed is relatively slow, and the interference to the aircraft is easily caused. The inclined guide rail type electric separating mechanism is low in separating speed, and the guide rail bracket is close to the projectile body, so that the inclined guide rail type electric separating mechanism is not suitable for the condition of large contraction distance.

The common connecting rod type electric separating mechanism is provided with a separating plug through two connecting rods, and the connecting rods are pulled to rotate through the tension springs during separation so as to complete the separation action. Design and test of an electric separation mechanism (the discourse of technical information exchange of 2008 technical information of the special Commission of China astronavigation), a four-bar separation mechanism is introduced, which utilizes the four-bar mechanism to drive a plug to move, and the plug moves forwards and downwards under the action of a tension spring and a connecting bar during separation, so that the separation of the plug and a socket of an electric connector is realized. The design of storage and transportation launch box structure and finite element analysis (electronic science and technology university engineering Master's academic thesis, 2009) propose a release and insertion mechanism in the form of a tension spring and a guide frame, wherein the tension spring assists to pull a plug to move in place along an inclined sliding groove during separation, so that the separation of the plug and a socket (aircraft) of an electric connector is realized.

The electric separation mechanism adopts single separation driving force as a power source, has low separation reliability, and does not adopt a device and a method for realizing quick contraction by adopting a guide rail.
