And another purpose of the insulating case is that a plurality of terminals can be provided to avoid the interference between the terminals or the potential difference caused by the potential difference, and the terminal is mainly used for connecting the metal wires between the electronic parts and the electronic parts. (commonly known as wire), or the wire between the electronic component and the circuit board, the electronic component includes a resistor, a capacitor, an inductor, an LED, a transformer, a liquid crystal panel, a touch panel, etc., thereby transmitting a power source or an electronic signal for convenience. Installation and configuration between electronic circuit boards and electronic components inside electronic devices.

However, electronic devices do not require the above-mentioned terminals and multiple terminals having an insulating casing in the use environment and structural design. For example, when a thinner structure electronic product requires less space, the insulating casing is disposed outside the terminal. The overall height is limited. For example, if the plurality of terminals are arranged in the above-mentioned insulating shell, the overall width is widened. Moreover, the increase of the insulating shell directly affects the increase of production cost and manufacturing cost, and the application of the plurality of terminals with the insulating shell is applied. Unipolar conduction can cause waste in space and cost.
