The charger is a power supply conversion device, and generally converts 220V commercial power into low-voltage direct current and provides the low-voltage direct current for electric equipment; among them, mobile phone chargers and notebook computer chargers are common chargers. In order to facilitate visual understanding of the working state of the charger, whether the charger works or not is judged by whether the indicator lamp is lighted or not; furthermore, the charging indicator lamp is additionally arranged in the charger, and the light guide column is arranged on the shell of the charger, so that the light guide of the indicator lamp is arranged outside the shell of the charger, and people can intuitively know the working state of the charger, namely, the use experience of a user is improved. The portable mobile phone charger has compact structure (the volume of the quick charging head is larger along with the increase of the quick charging power of the traditional charger, the carrying is very inconvenient, the charging head is easy to heat after long-time charging of some high-power chargers, the volume of the gallium nitride charger is smaller under the same power, the heat dissipation is more excellent, and the small-volume high-power can be easily realized), and furthermore, the limited internal space in the charger shell does not allow the light guide column to have larger volume; therefore, the light guide post on the charger housing in the prior art is often welded (hot-welded) or fixed on the charger housing by gluing; in the way of welding the light guide column and the shell, after the charger is assembled, the shell is required to be subjected to ultrasonic welding to finish final packaging of the charger, and a part of the light guide column and the shell are subjected to desoldering due to high-frequency oscillation in the welding process of the welding sound wave, namely, the qualification rate of a finished product of the charger is reduced; when the light guide column and the shell are fixed by gluing, glue overflows to influence the appearance of a finished product of the charger, and further influence the production quality of the charger.
