Abstract
The utility model belongs to switching device field, is related to a kind of switch contact, including mutually corresponding moving contact and static contact, moving contact connects movable feeler lever, movable feeler lever is provided with energy-stored spring, and moving contact includes dynamic feeler and moving contact main body, moves feeler and is set with moving contact main body in angle；Static contact includes stationary contact angle and static contact main body, and stationary contact angle is set with static contact main body in angle, and stationary contact angle is parallel with dynamic feeler.Dynamic feeler and stationary contact angle can closely be touched.The utility model is reasonable in design, and static contact is decomposed to moving contact spring, switchs the arcing caused by secondary bounce in making process and weakens, extends so as to the electrical endurance of switch.
Description
Technical field
A kind of switch contact is the utility model is related to, belongs to switching device field.
Background technology
The contact of switch currently used in the market is horizontal bridge architecture, and the contact of the structure type is in switch connection
When, due to movable feeler lever with moving contact with respect to static contact vertical movement, so that moving contact brings vertical impact to static contact, so
The spring formed by impulsive force easily causes switch secondary bounce arcing in making process with regard to bigger, influences the electricity of switch
The gas life-span.
Utility model content
The purpose of this utility model is to provide a kind of switch contact, and the switch contact decomposes spring, so as to bounce
Caused arcing weakens, and the electrical endurance of switch extends.
Switch contact described in the utility model, including mutually corresponding moving contact and static contact, moving contact connection is dynamic to touch
Bar, movable feeler lever are provided with energy-stored spring, and moving contact includes dynamic feeler and moving contact main body, and it is in angle to move feeler with moving contact main body
Set；Static contact includes stationary contact angle and static contact main body, and stationary contact angle is set with static contact main body in angle, stationary contact angle and dynamic feeler
It is parallel.Dynamic feeler and stationary contact angle can closely be touched.
In use, movable feeler lever is provided with coil, during switch connection, movable feeler lever moves with moving contact, moves feeler and stationary contact
Angle is touched, because dynamic feeler and stationary contact angle are set with moving contact main body and static contact main body in angle respectively, moves feeler
Face of touching with stationary contact angle is inclined-plane, therefore the spring of static contact suffered by moving contact is decomposed, switch in making process because
Arcing caused by secondary bounce will weaken, so as to improve the electrical endurance of switch.
Preferably, described dynamic feeler and moving contact main body angle are 10 degree of -70 degree.
Preferably, the correspondence at described dynamic feeler and stationary contact angle touches face and is equipped with contact.
Possessed beneficial effect is the utility model compared with prior art：
The utility model is reasonable in design, and static contact is decomposed to moving contact spring, switch in making process because
Arcing caused by secondary bounce weakens, and extends so as to the electrical endurance of switch.

Embodiment
The utility model is described further below in conjunction with the accompanying drawings：
Such as Fig. 1-Fig. 3, switch contact described in the utility model, including mutually corresponding moving contact and static contact, move and touch
Head connection movable feeler lever 1, movable feeler lever 1 are provided with energy-stored spring 2, and moving contact includes dynamic feeler 4 and moving contact main body 5, move feeler 4 and
Moving contact main body 5 is set in angle；Static contact includes stationary contact angle 7 and static contact main body 3, and stationary contact angle 7 is with static contact main body 3 in folder
Angle is set, and stationary contact angle 7 is parallel with dynamic feeler 4.
Embodiment 1：
Such as Fig. 1, dynamic feeler 4 tilts obliquely upward, and it is 40 degree to move feeler 4 and the extended line angle of moving contact main body 5, quiet
Feeler 7 oliquely downward tilts, and dynamic feeler 4 and stationary contact angle 7 can closely be touched, and moves the face mutually touched of the feeler 4 with stationary contact angle 7
It is equipped with contact 6.
Embodiment 2：
Such as Fig. 2, dynamic feeler 4 tilts obliquely upward, and it is 40 degree to move feeler 4 and the extended line angle of moving contact main body 5, quiet
Feeler 7 tilts obliquely upward, and dynamic feeler 4 and stationary contact angle 7 can closely be touched, and moves the face mutually touched of the feeler 4 with stationary contact angle 7
It is equipped with contact 6.
Embodiment 3：
Such as Fig. 3, dynamic feeler 4 oliquely downward tilts, and it is 40 degree to move feeler 4 with the angle of moving contact main body 5, and stationary contact angle 7 is equal
Oliquely downward tilt, dynamic feeler 4 and stationary contact angle 7 can closely be touched, and dynamic feeler 4 is equipped with the face mutually touched at stationary contact angle 7
Contact 6.
In use, movable feeler lever 1 is provided with coil, during switch connection, movable feeler lever 1 moves with moving contact, move feeler 4 with it is quiet
Feeler 7 touches, because dynamic feeler 4 and stationary contact angle 7 are set with moving contact main body 5 and static contact main body 3 in angle respectively,
It is inclined-plane to touch face, therefore the spring of static contact suffered by moving contact is decomposed, and is switched in making process because secondary bounce draws
The arcing risen will weaken, so as to improve the electrical endurance of switch.
