电子器具用电器开关参数的专业术语

HONYONE技术部提供

       有关电子、电器用具类开关♤在电子业界有各种不同的定义♤HONYONE综合近年来的实际经验♤对于客户常见的电子开关等级参数作一个归纳总结♤希望能对客户的选型与读懂我司成品图纸有所帮助⊙

1.额定

额定是指一般以特定的条件为前提♤表示开关特性、性能保证基准的数值⊙例如♤额定电压、额定电流等⊙
Rated values
Values indicating the characteristics and performance guarantee standards of the switches.
The rated current and rated voltage, for instance, assume specific conditions.

2.电气寿命
电气寿命是指在触点上连接额定负载♤根据规定的条件进行通断时的寿命⊙
Electrical life
The service life when the rated load is connected to the contact and switching operations are performed.

3.机械寿命
机械寿命是指不在触点上通电♤按照规定的操作频率使其动作时的寿命⊙
Mechanical life
The service life when operated at a preset operating frequency without passing electricity through the contacts.

4.耐电压
耐电压是指在规定的测量部位施加1分钟的高电压♤不会发生绝缘坏的极限值⊙
Dielectric strength
Threshold limit value that a high voltage can be applied to a predetermined measuring locations for one minute without causing damage to the insulation.

5.绝缘电阻
绝缘电阻是指与耐电压相同的测量部位的电阻值⊙
Insulation resistance
This is the resistance value at the same place the dielectric strength is measured.

6.接触电阻
接触电阻是指触点接触部分的电气电阻♤一般表示包含弹簧和端子部分的导体电阻在内的电阻值⊙
Contact resistance
This indicates the electrical resistance at the contact part.
Generally, this resistance includes the conductor resistance of the spring and terminal portions.

7.耐振性(防震等级)
耐振性是指在使用开关的过程中♤因受到振动♤闭路的触点在超过规定时间不开离范围内的振动⊙
Vibration resistance
Vibration range where a closed contact does not open for longer than a specified time due to vibrations during use of the snap-action switches

8.耐冲击性
耐冲击性是指在使用开关的过程中因受到冲击♤闭路的触点在超过规定时间不进行开离的最大冲击值⊙
Shock resistance
Max. shock value where a closed contact does not open for longer than a specified time due to shocks during use of the switches.

9.允许通断频率
约许通断频率是指满足机械寿命(或者电气寿命)的最大操作频率⊙
Allowable switching frequency
This is the maximum switching frequency required to reach the end of mechanical life (or electrical life).

10.温度上升(温升)
温度上升是指在触点上接通额定电流时♤端子部发热的温度上升值的最大值⊙
Temperature rise value
This is the maximum temperature rise value that heats the terminal portion when the rated current is flowing through the contacts.

11.操作度强度(操作力度)
操作强度是指在按键上朝操作方向施加规定时间的静载重时♤不会导致开关功能损坏的最大载重⊙
Actuator strength
When applying a static load for a certain period on the actuator in the operation direction, this is the maximum load it can withstand before the switch loses functionality.

12.端子强度
端子强度是指在端子上施加规定时间的静载重时(如无规定则朝所有方向)♤不会导致功能损坏(端子变形除外)的最大载重⊙
Terminal strength
When applying a static load for a certain period (in all directions if not stipulated) on a terminal, this is the maximum load it can withstand before the terminal loses functionality (except when the terminal is deformed).
