When using the headphone socket, we need to know and pay attention to some things. We will summarize these things and show them to you. The following is what we want to share with you.
(1) The rated current of the socket shall be selected according to the nature of the load. When using the socket, the starting current is very large. If the selected socket can not withstand the impact of the starting current within the required time, the contacts of the socket will appear arc, which will make the socket contacts burn together or cause the damage of the socket due to the arc splash.
(2) The voltage of the socket application circuit should be less than the rated voltage of the socket.
(3) The headphone socket company introduced that the insulation resistance of the socket used in municipal power supply should be paid attention to, and the socket with non-metallic operating handle should be selected.
(4) When the socket is connected to the circuit, the quality of contact connection will directly affect the load of the circuit. Therefore, the socket with small contact resistance should be selected in the circuit design, and the gold contact socket should be selected in the design of low power circuit and when necessary.
(5) The mechanical life and electrical life of headphone socket should be selected according to the use situation. When switching on and off frequently and with little load, the mechanical life of the switch should be emphasized when choosing the switch, and the electrical life of the switch should be emphasized when the switch bears high power.
If you want to use headphone sockets, you must understand and pay attention to these problems before using them.
