Description
Technical field
This utility model relates to technical field of automobile parts, particularly relates to a kind of travel switch.
Background technology
Travel switch is the important spare part in auto parts and components, and the quality of its quality directly affects the operation shape of automobile
State.
At present, general travel switch is contact pad formula mostly, and the problem existed mainly has:
Housing and base assembly use and directly rivet combination, and inner sealing uses and adds sealing between base bottom and housing
Pad, owing to gasket seal itself is softer, assembling is relatively slow, and in process of production, it is varied in size by external force, thus produces
Contraction different, cause different people to detect power different, certainty of measurement is the highest, causes the switch first-time qualification rate after riveting not
High；
Binding post and base assembly use Shooting Technique, certainly will exist the trickleest between binding post and plastic feet
Gap, with the presence of trickle gap, during switch life-time service external moisture and impurity the most easily invade the inside thus
Cause internal part to get rusty, produce impurity, cause contact to get rusty, make switch failure；
Push-rod assembly and housing coordinate the employing whole face of cylinder of friction-type to coordinate, and gap is less, without oil drainage structure at cooperation,
When under switch working state, the inside cavity that easy housing is formed with push rod is full of fluid, cause push rod can not Rapid reset, make
Become switch transmission signal inaccurate, and oil is along with the lengthening of the time of use, certainly will remain certain impurity in gear oil, produces
Frictional force is very big, causes switch plunger return difficulty, lost efficacy；
Existing contact typically uses copper contact, and the mar proof of contact and elastic life-span are poor, use a period of time
After, contact gradually wears out, and contact surface becomes relatively rough, and loose contact and arcing easily occurs in switch；Copper sheet knee also holds
Easily resilience, cause that switch contact is bad, ablation, inefficacy；Copper contact the connection terminal portion outside product common greatly
Corrosion in compression ring border or in acidic liquid, neutral liquid and akaline liquid is on its surface but in the work containing corrosive gas
In industry district air, then there is obvious corrosion phenomenon, thus affect switch energising performance.
Therefore, it is bad to there is sealing in current travel switch, push rod aftertaste difficulty, and contact is easy to wear, resilience, and assembling is tired
Difficulty, production certainty of measurement is low and produces the problems such as first-time qualification rate is low.
Utility model content
