Combined switch device

Technical Field

The invention belongs to the technical field of electrical control, and particularly relates to a combined switch device.

Background

The invention relates to a combined switch device, which is a key component for upgrading a mechanical controller product to an electromechanical controller product. Because the mechanical controller is generally controlled in a single mode, the mechanical controller can be upgraded into an electromechanical controller by applying the combined switch device, and conditions are created for realizing multi-mode multi-state program control and intelligent control. Traditional plug switch is simple, and circuit switch-on and circuit switch-off when extracting can only be accomplished when the bolt inserts, can not solve reverse work and circuit switch-on when the bolt inserts circuit switch-off and extracting. This reverse operation function needs to be implemented in an actual controller circuit by other complicated circuits, and a multifunctional combination device needs to be developed to simplify the design of a controller product.

Disclosure of Invention

The purpose of the invention is: a combined switch device is provided to solve the technical problem that multi-mode multi-state program control and intelligent control of controller products cannot be realized in many single-mode controllers at present.

In order to solve the technical problem, the technical scheme of the invention is as follows:

a combined switch device is composed of a combined switch and a metal bolt, wherein the combined switch comprises a first contact 1, a second contact 5, a reset piston 6 and a single-pole double-position switch; the combination switch is provided with a slotted hole matched with the metal bolt, and the first contact 1, the second contact 5 and the reset piston 6 are distributed on the periphery of the slotted hole;

the reset piston 6 is connected with the single-pole elastic sheet of the single-pole double-position switch;

the first contact 1 and the second contact 5 are metal sheets;

the single-pole double-position switch comprises a single-pole elastic sheet 2, a normally open contact 3 and a normally closed contact 4, and the single-pole elastic sheet 2 is communicated with the normally closed contact 4 in a normal state;

the metal bolt is a conductive metal spring close-wound structure, when the metal bolt is completely inserted into the combined switch, the first contact 1 and the second contact 5 are conducted, and the single-blade elastic sheet 2 is communicated with the normally-open contact 3 under the action of the reset piston 6.

The first contact 1 and the second contact 5 are copper sheets.

Detailed Description

The invention is further illustrated with reference to the following figures and examples:

the combined switch device of the invention comprises 1 combined switch schematic diagram as shown in figure 1 and 1 metal bolt schematic diagram as shown in figure 2. The combined switch comprises 2 first contacts 1 and second contacts 5 of copper metal sheets, 1 reset piston 6 and 1 single-pole double-position switch. The single-pole double-set switch comprises a single-pole elastic sheet 2, a normally open contact 3 and a normally closed contact 4. The metal bolt is a conductive metal spring close-wound structure.

The combined switching device can be used for a starting circuit of an electrical program control device. The working principle is as follows:

as shown in fig. 3, when the metal plug is inserted into the combined switch jack, the first contact 1 and the second contact 5 of 2 copper metal sheets are conducted, the reset piston 6 moves rightwards, and the single-pole elastic sheet 2 and the normally open contact 3 of the single-pole double-position switch are conducted as shown in fig. 4; as shown in fig. 5, when the metal plug is pulled out of the switch base hole, the first contact 1 and the second contact 5 of the 2 copper metal sheets are disconnected, the reset piston 6 moves leftwards, and the single-blade elastic sheet 2 and the normally closed contact 4 of the single-blade double-position switch are conducted as shown in fig. 1.

The application scene one: the electronic automatic parachute opening device for the airborne troops is used for tasks such as airborne delivery, and a starter of the electronic automatic parachute opening device can use the combined type switch device. Before the air-drop task is executed, the plug pin is inserted into the plug switch seat and is fixed on the airplane through the rope, after people or objects jump away from the airplane, namely air-drop, the plug pin is pulled out, the electronic automatic parachute opener starts to work, and the parachute is opened when the requirements of specified conditions are met. The single-pole double-set switch can be used for switching power supply from an external power supply to internal battery power supply.

Application scenario two: the ejection seat program controller is used for the ejection lifesaving of pilots, and the like, and the combined switch device can be used by the starter of the ejection seat program controller. Before the ejection task is executed, the plug pin is inserted into the plug switch seat and is fixed on the airplane through the rope, after the seat is ejected away from the airplane, the plug pin is pulled out, the ejection seat program controller starts to work, and the parachute and the seat are controlled to be separated when the requirements of specified conditions are met. The power supply of the airborne power supply can be switched to the power supply of the seat internal power supply battery by using the single-pole double-set switch.
