微动开关专业术语，你了解多少
微动开关已广泛应用于各行各业，应用在各类电子产品及家电设备中，虽然非常贴近我们的生活，但大多数人对于微动开关这个名称还是比较陌生的，作为微动开关生产厂家，星坤科技这里向大家分享部分微动开关的基础专业术语，帮助大家用专业的眼光认识微动开关。 微动开关：具有微小接点间隔和快动机构，用规定的行程和规定的力进行开关动作的接点结构，用外壳覆盖，其外部有驱动杆的一种开关。（以下称开关）有接点：在开关类型中，和具有开关特性的半导体开关相比，通过接点的机械开关来实现开关的功能。接触形式：根据各种用途构成接点的电气输入输出电路。 额定值：一般指作为开关特性和性能的保证基准的值，例如额定电流、额定电压等，其前提是特定的条件（负载的种类、电流、电压、频率等）。 树脂固定（塑封端子）：在端子部位用导线配线后，通过填充树脂来固定该部分，消除露出的带电部位来提高防滴性的方法。 绝缘电阻：指非连接端子间、各端子和不带电金属部位间、各端子和地间的电阻值。 耐压：微动开关厂家在规定的测定部位加1分钟高电压后，不会引起绝缘损坏的临界值。 接触电阻：表示接点的接触部位的电阻，但一般表示包含弹簧和端子部位导体电阻的电阻值。 抗振性：误动作振动微动开关在使用时，由于振动闭合的接点在超过规定的时间内不分离的振动范围。 抗冲击性：耐久冲击指微动开关在运输中或者安装时不会受到由该机械冲击带来的各部位的损伤，并满足动作特性的范围内的冲击。 误动作冲击指微动开关使用时由于冲击闭合的接点在超过规定的时间内不分离的冲击范围。 机械寿命:指接点不通电,以规定的操作频率将过行程(OT)设定为规格值使其运行时的开关寿命。 电气寿命:在接点上连接额定负载,以规定的操作频率将过行程(OT)设定为规格值进行开关时的开关寿命。 更多有关微动开关专业术语或相关知识，欢迎访问星坤官网或者星坤客服人员索取：www.helloxkb.com。 Micro switch terminology, how much do you know? Micro switch has been widely used in all walks of life, applied in all kinds of electronic products and appliances, although very close to our lives,but most of people are not familiar with micro switch,as a micro switch manufacturer, XKB technology company here to share some of the micro switch basic terminology to help you with a professional eye to understand the micro switch. A miniature snap-action switch, also trademarked and frequently known as a micro switch, is an electric switch that is actuated by very little physical force, through the use of a tipping-point mechanism, sometimes called an "over-center" mechanism. Rating value: Generally refers to the value of the guarantee of the switch characteristics and performance, such as the rated current, the rated voltage, etc., and the premise is a certain condition (the type of load, the current, the voltage, the frequency, etc.). Resin fixation (plastic sealing terminal):After wiring the terminal with wires, fix the part by filling resin and eliminate the exposed live part to improve the drip-resistance. Insulation resistance: Refers to the value of resistance between unconnected terminals, between terminals and parts of uncharged metal, between terminals and ground. Withstand voltage: Micro-switch manufacturers in the specified measurement of the location of 1 minute high voltage, will not cause insulation damage threshold. Contact resistance:The resistance of the contact area of the contact point, but it is usually said to contain the resistance of the conductor resistance in the spring and terminal. Vibration resistance: When the misoperation vibration micro switch is in use, the contact point closed by vibration does not separate the vibration range within the specified time. Impact resistance: Durable impact refers to the micro switch in transportation or installation will not be affected by the mechanical impact of all parts of the damage, and meet the range of motion characteristics of the impact. Mechanical life: Refers to the switch life when the contact is not energized and the over travel (OT) is set as the specification value at the specified operating frequency to enable it to operate. Electrical life: The switching life when the rated load is connected to the contact and the overtravel (OT) is set as the specification value at the specified operating frequency.
