Description
Technical field
The utility model relates to engine ignitor technical field, particularly relates to a kind of ignition switch.
Background technology
Ignition switch Main Function starts/close the use of starting, therefore current loading is very large, in prevailing conditions technology for high-current switch, the electric arc of the larger generation of electric current is larger, and electric arc is the key factor affecting switch useful life and fail safe, the heat formed during the break-make of switch is more, the useful life of switch is shorter, and ignition switch is critical component on automobile, the factors such as ignition switch nonfunctional or contact instability, the fail safe of vehicle can be had influence on, directly cause can not using of vehicle.Existing ignition switch structure is a lot, but controls the rare design of this point to electric arc.As a kind of ignition switch that patent publication No. is CN102709097A, comprise housing and be arranged on the ignition lock cylinder in housing, with igniting lock core joining switch block and rear case component successively, sideboard and activity orientation block is provided with in switch block, sideboard one end is pressed on switch block inwall by sideboard back-moving spring, and the other end is pressed on housing with on the end face inwall that coordinates of igniting lock core; Have slot in the middle of sideboard, activity orientation block is buckled on the limit of sideboard slot by boss structure, and one end of activity orientation block is pressed on switch block by activity orientation block reset spring; The end face inwall that housing coordinates with igniting lock core is provided with sideboard reset track.This device can avoid automobile unsuccessful, to return initial bit and continuous ignition without lock core situation of once lighting a fire to occur.And for example patent publication No. is CN1963180A, a kind of automobile ignition switch proposed, comprise body and bonnet, the actuating rod that body arranges ignition lock and key thereof, be connected successively with lock core and switch block, after be covered with binding post and at least 2 annular slide tracks, annular slide track is provided with some spaced apart conducting strips, conducting strip and binding post electric phase respectively; Switch block is positioned at actuating rod side and has cannelure, and opposite side has the axle and the contact bridge corresponding with annular slide track that are rotatably assorted with bonnet; In cannelure, torsion spring is housed, one end snaps onto on the boss of body, and the other end is resisted against on the outer wall of cannelure; Contact bridge is provided with reed and is connected with annular slide track sliding contact by reed.This device adopts multiple spot flow dividing structure, and by original very large electric current, reduced the operating current of contact by design, the heat concentrated is decomposed, and complex structure cost is high.
Summary of the invention
The purpose of this utility model is the high-current switch in order to solve under current art condition, the problem that ignition switch nonfunctional or contact instability and switch life are short is affected because producing large electric arc, a kind of reasonable in design is provided, sealed environment is become in switch on and off Position Design, form an oxygen-free space, the electric arc that electric current is produced is less or do not produce the ignition switch of electric arc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of rotary switch, comprise the base coordinated with latch mechanism, the outer cover coordinated with one end cylindrical of base vertically, it is characterized in that base coordinates formation inner chamber sealed with outer cover, rotation pellet is provided with in this inner chamber, outer cover one end is stretched out in the coupling of rotating pellet, and and between outer cover, be provided with the first sealing ring, the other end of base is provided with pin, and pin and base engagement place are provided with epoxy resin embedding adhesive layer.
The technical program, as a kind of ignition switch of automobile, is generally installed on the latch mechanism of car steering tube column, and its effect is energising, to open or the main circuit of closing automobile ignition coil, is certainly equally applicable in other appliance circuits of automobile.Because whether it accurately, reliably can realize powering-on function, i.e. whether startup/closedown the operating state of car electrics power supply, engine, directly can affect vehicle can fail safe normally in On/Off and driving process.The profile of shape is limited with base and outer cover, rotation pellet and pin are all adopted sealing device with the contact site that coordinates of contour structures, after use first time igniting, just the closed cavity making base coordinate with outer cover to form and the external world substantially isolated, thus avoid electric arc to contact with oxygen phenomenons such as causing oxidation.
As preferably, in the inner chamber that described rotation pellet is formed at base and outer cover, one end is provided with the first full silver contact, and base core is provided with the second full silver contact that silver contact complete in first coordinates.During work, be connected with the second full silver contact with the first full silver contact and be energized.
As preferably, described rotation pellet is stretching out outer cover section and outer cover matching part is provided with torsion spring.Torsion spring, also referred to as back-moving spring, automatically resets after igniting, makes the first full silver contact and the second full silver contact keep disengaged position.
As preferably, described rotation pellet and base engagement position are provided with triangle movable contact spring, and the first full silver contact is positioned on triangle movable contact spring.This programme adopts rotation body structure, and when doing rotation igniting, triangle movable contact spring drives the first full silver contact to shift to the second full silver contact.
As preferably, described base with rotate pellet matching part and be provided with round movable contact spring, circle movable contact spring is provided with round movable contact spring spring towards rotation pellet one end.Circle movable contact spring is fixed on base, and flat using state circle movable contact spring spring handle is opened base and rotates pellet.
As preferably, the position that described base coordinates with latch mechanism is provided with the second sealing ring.Be conducive to assembling and dismounting.
The beneficial effects of the utility model are: be a sealed environment in the break-make Position Design of switch, an oxygen-free space can be formed after the oxygen of the complete inside of arc burning, the electric arc that the environmental energy of opposing seal makes electric current produce is less or produce without electric arc, thus substantially prolongs switch life; The environmental benefits of sealing, in waterproof and dustproof, antirust, therefore also improves the service life of switch indirectly.
