Abstract
The utility model relates to a switch, particularly an automobile electronic type neutral gear, back gear signal switch device for automobiles, which is characterized in that the shape of an outer housing (1) is in a convex shape, a guide rod (2) is positioned at the small head end of the convex shape, and the outer surface of the small head end of the guide rod (2) is provided with an installation screw thread, an annular magnet (3), a release spring (4), a dry reed pipe (5) and a seal ring (6). A circuit board (7) is positioned in a seal cavity of a convex-shaped big head end, the connecting point of a seal cover (8) and the outer housing (1) is sealed by the seal ring (6), the big head end is sealed, and a switch leading wire (9) is connected with an outer circuit through two leading wire holes of the seal cover. The guide rod (2) is sheathed with the annular magnet (3), one end of the release spring (4) supports the guide rod (2), and the other end supports a circuit board bracket (10). The utility model has the advantages that structure is simple, cost is low, operation is safe, use is convenient, life is long and a power supply does not need alone supply.
Description
Technical field: the utility model relates to switch, is specially a kind of automobile automotive electronics formula neutral gear, reverse gear signal switching device.
Background technology: a few days ago, the neutral gear and the reverse gear signaling switch that use at the present automobile of China are mechanical type hard contact switch mostly.Wherein the neutral gear signaling switch is normal opened type (conducting during free state), and promptly this switch is in conducting state during automobile place fourth neutral state, and this switch disconnects (ending) during non-neutral state.The automotive reverse gear switch just in time with the neutral switch opposite states, be often-cutting type (during free state by).Switch conduction when automobile is in the reverse gear state, the automotive reverse gear indicator light is bright.Normal off during non-reverse gear state, the reverse gear indicator light does not work.Its two structural principle is roughly the same, all is the guide rod of switch when being positioned at free state and confined state, makes the disconnection of two hard contacts of switch inside or closed and " opening " and " pass " that realize switch.The problem that exists: because the supply voltage that car electrics use mostly is direct current 12V or 24V, and about the load 20-50W of neutral gear (reverse gear) signaling switch, that is to say electric current 1-4A by switch, the electric spark that the hard contact of switch produces in closure, the disconnection process under this current status is ablated the contact gradually, can sharply quicken the ablation of contact when particularly frequently using and cause the switch actual effect.Facts have proved that traditional mechanical type hard contact is opened is difficult to reach 100,000 big fatigue life.
Summary of the invention: the purpose of this utility model is to provide a kind of simple in structure, with low cost, safe and reliable, reliability height, the proof voltage impact property is good, the life-span is long Electronic Control simulated automotive electronic type neutral gear, reverse gear signal switching device.The purpose of this utility model is achieved in that it comprises shell (1), guide rod (2), ringshaped magnet (3), return spring (4), tongue tube (5), sealing ring (6), circuit board (7), seal cover (8), switch leads (9).Shell (1) shape is " protruding " type, guide rod (2) is positioned at the little head end of " protruding " type, guide rod (2) microcephaly holds the outside that the installation screw thread is arranged, ringshaped magnet (3), return spring (4), tongue tube (5), sealing ring (6), circuit board (7) are positioned at the stub end annular seal space of " protruding " type, seal cover (8) has sealing ring (6) sealing with shell (1) junction, make the stub end sealing, switch leads (9) is connected with external circuit by two fairleads of seal cover.Be with ringshaped magnet (3) on guide rod (2), return spring (4) one ends withstand on the guide rod (2), the other end withstands on the circuit board support (10).The utility model has the advantages that: simple in structure, with low cost, safe and reliable, easy to use, the life-span is long, does not need to provide separately power supply.
Description of drawings: Fig. 1 is the utility model structural principle schematic diagram.
Embodiment: shell (1) shape is " protruding " type, guide rod (2) is positioned at the little head end of " protruding " type, guide rod (2) microcephaly holds the outside that the installation screw thread is arranged, ringshaped magnet (3), return spring (4), tongue tube (5), sealing ring (6), circuit board (7) are positioned at the stub end annular seal space of " protruding " type, seal cover (8) has sealing ring (6) sealing with shell (1) junction, make the stub end sealing, switch leads (9) is connected with external circuit by two fairleads of seal cover.Be with ringshaped magnet (3) on guide rod (2), return spring (4) one ends withstand on that armed lever (2) is gone up, the other end withstands on circuit board support (10)) on.The utility model course of work: the utility model is installed in the special use of automobile variable speed box cover the vacancy is installed.When automobile is in neutral state, no matter be neutral gear signaling switch or reverse gear signaling switch, free position during its guide rod (2) is in shown in the figure one, the ringshaped magnet of switch inside (3) just is positioned at the centre position of tongue tube (5), this moment is identical by the magnetic flux of two reeds of tongue tube, two reeds still are in the normal state (not contact), and the circuit in the circuit board (7) is in neutral gear conducting, reverse gear cut-off state all the time.It promotes ringshaped magnet (3) and moves together and depart near the center of tongue tube (5) when switch is inner mobile by selector fork compression when guide rod (2), the magnetic flux difference of passing through in two reeds of tongue tube and adhesive conducting.After circuit in the circuit board received this signal, circuit promptly changes operating state made that neutral switch ends, the reverse gear switch conducting.When selector fork is shifted to neutral gear, guide rod (2) is removed compression, effect lower guide rod (2), ringshaped magnet (3) at return spring (4) return to free state, and this moment, switch conduction and cut-off state also returned to initial condition, and whole process has promptly been finished " opening ", " pass " process of switch.
Claims (2)
1, a kind of automotive electronics formula neutral gear, the reverse gear signal switching device, it comprises shell (1), guide rod (2), ringshaped magnet (3), return spring (4), tongue tube (5), sealing ring (6), circuit board (7), seal cover (8), switch leads (9), it is characterized in that: shell (1) shape is " protruding " type, guide rod (2) is positioned at the little head end of " protruding " type, guide rod (2) microcephaly holds the outside that the installation screw thread is arranged, ringshaped magnet (3), return spring (4), tongue tube (5), sealing ring (6), circuit board (7) is positioned at the stub end annular seal space of " protruding " type, seal cover (8) has sealing ring (6) sealing with shell (1) junction, make the stub end sealing, switch leads (9) is connected with external circuit by two fairleads of seal cover.
