Description
Technical field
The utility model is related to switching device technical field, more particularly to a kind of brake signal transmits switch.
Background technology
It is a most important device on automobile that brake signal, which transmits switch, and the brake signal of safety and stability transmits switch and closes
It is the life security to people.Existing brake signal transmits the general differential type servo for being all mounted on chassis braking gas circuit of switch
On valve, this relay valve normal open gas is deflated when parking brake is pulled on, and realizes parking braking.When parking brake discharges, differential type relay valve is normal
It ventilates, the pressure in gas circuit is more than operating pressure, and parking brake switch is off at this time；When parking brake is pulled on, differential type after
Dynamic valve exhaust, the pressure in gas circuit are less than operating pressure, and parking brake switch is closed at this time, is lighted parking braking alarm lamp, is played report
Alert effect.
Traditional brake signal transmits the adjusting that switch cannot adjust due to acting air pressure or can only be by a small margin, it is impossible to adapt to
Various action air pressures；Gas circuit is typically mutually mixed with circuit in structure design simultaneously, causes product stability not high, electricity
Road is highly prone to the influence of various unfavorable factors in gas circuit and influences to use.
Utility model content
Technical problem to be solved in the utility model is in view of the deficiencies of the prior art, to provide a kind of system simple in structure
Dynamic signal transfer switch.
To achieve these goals, the technical solution of the utility model is：
A kind of brake signal transmits switch, and including threaded block, plug connector, sealing is compressed between the threaded block and briquetting
There are O-ring seal and diaphragm, the diaphragm seat of the film contact passes through embedded copper sheathing and pushing block slide fit, the diaphragm seat
Compressing piece is equipped between pushing block, the pushing block realizes break-make by the way that the spring force of spring is overcome to touch micro-control switch, described
Micro-control switch be soldered in the circuit board, the wiring board is connect with plug connector contact pin.
Further, sealing ring is equipped between the threaded block and plug connector.
Further, the spring one end withstands pushing block, other end connecting spring gasket.
Further, the spring shim attachment screw dummy slider, the screw dummy slider that connects are equipped with to fix bullet
The screw of spring.
Further, the contact pin totally three connect normally opened contact NO, normally-closed contact NC, common end COM respectively.
Utility model works principle：When automobile normal running does not brake, no power is applied on diaphragm, due to bullet
The effect of spring, pushing block can not act on micro-control switch, and switch is off at this time；When touching on the brake, pressure switch impression
The pressure arrived rises, and diaphragm deformation pushes pushing block, and pushing block overcomes spring pressure to touch micro-control switch, switch connection.
The beneficial effects of the utility model：Gas circuit and circuit are detached by Kapton, avoided due to gas circuit
In moisture and the impurity burn into such as greasy dirt pollution circuit, so as to improve the stability of product, reliability and durability；Braking
Signal transfer switch is simple and compact for structure, and not easy to wear, and service life is long, and maintenance cost is low.

Specific embodiment
Specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.
As shown in Figs. 1-3, a kind of brake signal transmits switch, including threaded block 2, plug connector 17, the threaded block 2
It is compressed between briquetting 4 and is sealed with O-ring seal 2 and diaphragm 3, the diaphragm 3 is Kapton, with the diaphragm
The diaphragm seats 5 of 3 contacts are by embedded copper sheathing 7 and 8 slide fit of pushing block, equipped with compressing piece 6 between the diaphragm seat 5 and pushing block 8,
The pushing block 8 realizes break-make by the way that the spring force of spring 10 is overcome to touch micro-control switch 12, and the micro-control switch 12 is by tin
It is welded on wiring board 13, the wiring board 13 is connect with 17 contact pin 18 of plug connector.
Sealing ring 11 is equipped between the threaded block 1 and plug connector 17.
Withstand pushing block 8, other end connecting spring gasket 14 in described 10 one end of spring.
The 14 attachment screw dummy slider 15 of spring shim, the screw dummy slider 15 that connects are equipped with for fixed spring 10
Screw 16.
The contact pin 18 totally three connects normally opened contact NO19, normally-closed contact NC20, common end COM21 respectively.
When automobile normal running does not brake, no power is applied on diaphragm 3, due to the effect of spring 10,8 nothing of pushing block
Method acts on micro-control switch 12, and switch is off at this time；When touching on the brake, the pressure that pressure switch is experienced rises,
3 deformation of diaphragm pushes pushing block 8, and pushing block 8 overcomes spring pressure to touch micro-control switch 12, switch connection.
