Outline： Shock resistance and shock resistance are critical performance of connectors, especially in harsh environments, where privacy is critical.

We all know that the basic performance of electronic device connectors includes three categories, namely, mechanical equipment performance, electrical performance and its natural environment performance, and the basic nature of connectors

It can directly depend on whether it can be started normally. Let's take a brief look at these three features.

1. Mechanical equipment performance. In terms of the overall connection efficiency, the insertion and extraction force is a very important mechanical equipment performance. The insertion and extraction force includes two parts: the insertion force and the extraction force. Due to functional differences, the provisions of the two are different. From the user's point of view, the insertion force is relatively small, but the separation force cannot be small, so as not to cause touch stability.

2. Electrical performance. Electrical performance includes three major parts, namely, grounding resistance, electrical compressive strength and circuit resistance. Among them, the grounding resistance is an important factor to test the performance of the insulation layer between the circuit breaker and the case. The circuit resistance is required to be low and stable. Generally, it varies from a few milliohms to dozens of milliohms. The electrical compressive strength is the working voltage capacity that the connector can withstand.

3. Natural environmental performance. Common natural environment performance: high temperature resistance, humidity resistance, salt fog resistance, vibration resistance and impact resistance. The temperature resistance environment temperature of most connectors is 200 ℃ - 65 ℃. Humidity cooling has a great impact on the performance of connectors, which may reduce the insulation performance. Some better connectors can withstand humidity up to 90%~95%, or even 98%. Salt spray resistance means that the connector's performance will not be greatly affected when it is used in the salt and water environment. Generally, 48 hours of salt spray test is required.

Shock resistance and shock resistance are critical performance of connectors, especially in harsh environments, where privacy is critical.

Detection switch, a kind of position switch (also known as travel arrangement switch, positioning switch), is a common electrical product of low current cam controller. The production and processing kinetic energy components shall be used to impact the isolator to complete the connection or disconnection of the control circuit to ensure a certain control purpose. In general, this switch is used to limit the position or schedule of molecular thermal exercise, so that the industrial equipment for sports and fitness can automatically stop, repeatedly exercise, speed change exercise or automatic back and forth sports and fitness according to a certain position or schedule.
