Abstract
The utility model belongs to the field of aviation onboard electronic equipment technology and relates to a detonation control box comprising a box body, a box cover, a safety pin, a safety pin sleeve, a spring piece provided with a support pillar, an L-shaped reed, and a microswitch. The safety pin is connected to the box body and is inserted into the box body through the safety pin sleeve; the box cover seals the box body; the L-shaped reed is installed in the box body; one end of the L-shaped reed is fixed on the inner wall of the box body; the middle L-shaped projection of the L-shaped reed is attached to the inner wall of a channel in the box body, the channel allowing the safety pin to pass through; and the other end of the reed is connected with a button of the microswitch disposed in the box body. The detonation control box enables the reed to deform when the safety pin is inserted in the box body and applies pressure to the reed and to work on the button of the microswitch for switching on and off a circuit, thereby preventing maloperation of an onboard product during grounding of an aircraft effectively. The detonation control box prevents the safety pin from falling off because of vibration even in a vibration environment, thereby being safe and reliable and meeting the requirements of related tests.
Description
Technical field
The utility model belongs to the airborne technical field of electronic equipment, relates to a kind of initiation control box.
Background technology
During the actual use of certain airborne products, when running into the water breakthrough signal at ordinary times, can produce explosion.Yet only water breakthrough explosion when state of flight of designing requirement, when aircraft was parked, certain airborne products should avoid water breakthrough (like rainwater) that explosion takes place.One cover insurance control device need be installed for this reason, improve the security performance of airborne products.
The utility model content
The utility model purpose is: when being provided, a kind of grounding make certain airborne products can not produce maloperation, and safety plug difficult drop-off during vibration, safe and reliable initiation control box.
The utility model technical scheme is: the initiation control box; It comprises box, lid, safety plug, insurance guide, L type reed, microswitch, and wherein, the safety plug cover is connected on the box; Safety plug inserts box through the insurance guide; The lid sealed box, said L type reed is installed in cassette interior, and an end of this L type reed is fixed on the box inwall; Be used for the vias inner walls applying that safety plug passes in middle L type bossing and the box, the reed other end contacts with the button of the microswitch that is arranged on cassette interior.
Said safety plug waist has a cannelure.
The side external surface that said box is connected with the insurance guide is provided with band fore-set spring leaf, and this spring leaf fore-set is stuck in the cannelure of safety plug when safety plug inserts.
Said safety plug afterbody has boss, and insurance guide afterbody has the back-shaped groove that is used to block boss.
Said microswitch is fixed on the box bottom surface through double-screw bolt.
The utility model technique effect is: the utility model initiation control box is based on the mechanism of spring reed; Designed a cover safety plug device; When utilizing safety plug to insert reed is exerted pressure, make reed generation deformation, reed acts on the button of microswitch; Reach disconnected, the logical purpose of circuit, thus the maloperation of airborne products can effectively avoid the aircraft grounding time.Even under vibration environment, safety plug is not subject to vibration and comes off, and is safe and reliable, possesses the excellent protection measure, satisfies the correlation test requirement.

The specific embodiment
Through specific embodiment the utility model is further specified below:
The utility model initiation control box is used to control the signal transmission of certain airborne products, and a kind of insurance control of avoiding maloperation is provided, and improves the security reliability of airborne products.
See also Fig. 1, it is the structural representation of the utility model initiation control box.Said initiation control box comprises box 1, lid 2, safety plug 3, insurance guide 4 and band fore-set spring leaf 5.Wherein, the safety plug cover is connected on the box, and safety plug inserts box through the insurance guide, the lid sealed box, and band fore-set spring leaf is arranged on an outer surface of box.
See also Fig. 2, it is the internal structure sketch map after the initiation control box is removed lid.Said cassette interior is equipped with a L type reed 6 (as shown in Figure 4); One end of this L type reed is fixed on the box inwall; Be used for the vias inner walls applying that safety plug passes in middle L type bossing and the box; The reed other end contacts with the button of the microswitch that is arranged on cassette interior, and said microswitch is fixed on the box bottom surface through two double-screw bolts.
See also Fig. 3, when safety plug inserts box through guide, safety plug jack-up L type reed 6, the button of microswitch 7 is pressed in the reed distortion, thereby cuts off the transmission of airborne product signal, avoids occurring maloperation.When safety plug was extracted, L type reed restored to the original state, and the button of microswitch is upspring, and the airborne products signal is in on-state.
In addition, for pointing out the safety plug insertion to put in place and stepping up safety plug, the possibility of avoiding safety plug in vibration, to exist nature to come off is simultaneously please consulted Fig. 5, Fig. 6, Fig. 7, Fig. 8 simultaneously.Said safety plug waist has a cannelure, and afterbody has a boss.After safety plug inserted, the fore-set of band fore-set spring leaf was stuck in the cannelure of safety plug, had played the effect that prompting puts in place and steps up, and is as shown in Figure 3.The afterbody of insurance guide has been processed a back-shaped groove, after the boss of safety plug afterbody gets into the back-shaped groove of guide, arrives top, dextrorotation, drop-down, and the safety plug boss is sticked in the back-shaped groove of insurance guide, and is as shown in Figure 8, avoids safety plug coming off when vibration.
In addition; The cassette material aluminium alloy of the utility model; Obtaining inside with the method for Milling Process has and is used for the passage that safety plug passes; And this passage has an open recess and is used to be provided with L shaped spring leaf, and cassette interior is provided with the mechanism that is used for fixing microswitch simultaneously, and overall structure is as shown in Figure 9.Said lid adopts aluminum alloy materials to process profile such as Figure 10.L type reed all adopts the beryllium-bronze bending process to form with band fore-set reed, has guaranteed better elastic.Safety plug all adopts stainless steel to be processed into the insurance guide, has excellent corrosion resisting performance.
