Abstract
The utility model discloses a kind of shift knob structure of contact terminal, comprise moving contact and fixed contact, described fixed contact comprises installation portion and conducting portion, on described conducting portion, be provided with the contact with moving contact laminating conducting, between described conducting portion and installation portion, be angle setting and described conducting portion with the end face of contact one side towards moving contact lopsidedness, the utility model is a kind of reduces the shift knob structure of contact terminal of the distance that moving contact and fixed contact carry out, and has improved the sensitivity of conducting between moving contact and fixed contact.
Description
Technical field
The utility model relates to a kind of structure of contact terminal, and more particularly, it relates to a kind of shift knob structure of contact terminal.
Background technology
Shift knob structure of contact terminal generally comprises moving contact and fixed contact, the movement of controlling moving contact reaches the separation of fitting between moving contact and fixed contact and realizes switch, on described fixed contact, be provided with contact, it when moving contact moves, is mainly the conducting realizing behind the contact of contact on fixed contact with fixed contact, in prior art, the contact of fixed contact and installation portion are usually located in same level, contact only depends on the evagination of self to coordinate with moving contact, like this moving contact need to move that very large distance could realize and fixed contact between conducting, and shift knob in use for some time, internal structure is when dispatching from the factory so after compactness, often occur that shift knob is malfunctioning, need to press with strength button could realize moving contact and contact with fixed contact.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of shift knob structure of contact terminal that reduces the distance that moving contact and fixed contact carry out, and has improved the sensitivity of conducting between moving contact and fixed contact.
For achieving the above object, the utility model provides following technical scheme: a kind of shift knob structure of contact terminal, comprise moving contact and fixed contact, described fixed contact comprises installation portion and conducting portion, on described conducting portion, be provided with the contact with moving contact laminating conducting, between described conducting portion and installation portion, be angle setting and described conducting portion with the end face of contact one side towards moving contact lopsidedness.
By adopting technique scheme, between described conducting portion and installation portion, be provided with some angles and described conducting portion towards moving contact lopsidedness, make the Distance Shortened between conducting portion and moving contact, guaranteeing that the convenient prerequisite of installing of installation portion makes the contact between conducting portion and moving contact sensitiveer, be more convenient for the conducting between conducting portion and moving contact, make inner structure compacter, long-term use still can guarantee the sensitivity of structure of contact terminal conducting.
The utility model is further set to: the angle between described conducting portion and installation portion is 1-2 degree.
By adopting technique scheme, through our actual experiment repeatedly, detect, the conducting portion of surveying and the angle between installation portion are that 1-2 is most suitable while spending, under this angle, in the time of the sensitiveest contact can being guaranteed between the contact of conducting portion and moving contact, can also guarantee that shift knob internal structure is compact stable, do not need to increase the external form size of shift knob on existing market, without mold again, saved production cost.
The utility model is further set to: described contact end face is plane layout, and described contact end face is coated with the silver that a layer thickness is 0.5-1 millimeter.
By adopting technique scheme, contact end face is set to plane, has strengthened the contact area between contact and moving contact, improved the contact effect between moving contact and contact, and contact end face is silver coated, has improved the electric conductivity of contact.
The utility model is further set to: described contact end face carries out coarse processing.
By adopting technique scheme, contact end face is carried out can improving the contact effect between moving contact and contact after coarse processing, the end face that prevents from getting an electric shock is too smooth to be slided away when making to contact between moving contact and contact, there is occurring suddenly again after conducting situation about disconnecting, improved the stability while contacting between moving contact and contact.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model shift knob structure of contact terminal embodiment.
Drawing reference numeral explanation:
1, moving contact; 2, fixed contact; 21, installation portion; 22, conducting portion; 3, contact.
Embodiment
With reference to Fig. 1, the utility model shift knob structure of contact terminal embodiment is described further.
A kind of shift knob structure of contact terminal, comprise moving contact 1 and fixed contact 2, described fixed contact 2 comprises installation portion 21 and conducting portion 22, on described conducting portion 22, be provided with the contact 3 with moving contact 1 laminating conducting, between described conducting portion 22 and installation portion 21, be angle setting and described conducting portion 22 with the end face of contact 3 one sides towards moving contact 1 lopsidedness.
By adopting technique scheme, between described conducting portion 22 and installation portion 21, be provided with some angles and described conducting portion 22 towards moving contact 1 lopsidedness, make the Distance Shortened between conducting portion 22 and moving contact 1, guaranteeing that the convenient prerequisite of installing of installation portion 21 makes the contact between conducting portion 22 and moving contact 1 sensitiveer, be more convenient for the conducting between conducting portion 22 and moving contact 1, make inner structure compacter, long-term use still can guarantee the sensitivity of structure of contact terminal conducting.
Angle between described conducting portion 22 and installation portion 21 is 1-2 degree.
By adopting technique scheme, through our actual experiment repeatedly, detect, the conducting portion 22 of surveying and the angle between installation portion 21 are that 1-2 is most suitable while spending, under this angle, in the time of the sensitiveest contact can being guaranteed between the contact of conducting portion 22 and moving contact 1, can also guarantee that shift knob internal structure is compact stable, do not need to increase the external form size of shift knob on existing market, without mold again, saved production cost.
Described contact 3 end faces are plane layout, and described contact 3 end faces are coated with the silver that a layer thickness is 0.5-1 millimeter.
By adopting technique scheme, contact 3 end faces are set to plane, have strengthened the contact area between contact 3 and moving contact 1, have improved the contact effect between moving contact 1 and contact 3, and contact 3 end faces are silver coated, have improved the electric conductivity of contact 3.
Described contact 3 end faces carry out coarse processing.
By adopting technique scheme, contact 3 end faces are carried out can improving the contact effect between moving contact 1 and contact 3 after coarse processing, the end face that prevents from getting an electric shock is too smooth to be slided away when making to contact between moving contact 1 and contact 3, there is occurring suddenly again after conducting situation about disconnecting, improved the stability while contacting between moving contact 1 and contact 3.
