Description

USB power socket

This creation is about a USB power socket, especially an innovative automotive USB connector.

Press, the two ends of the car charger of the general car are the cigarette lighter plug and the USB connector, after using the cigarette lighter plug to insert the cigarette lighter socket in the car, and then connect the electronic product with the USB connector to charge the electronic product.

However, in addition to the central electrode (i.e. "+" pole) protruding from the end of the cigarette lighter plug, a pair of electrode springs (i.e. "-" pole) protruding from both ends of the cigarette lighter plug The cigarette lighter plug is a plastic shell. When it is plugged into a cigarette lighter socket in the car, the USB power socket product may be suspected of melting at high temperature. Moreover, the conventional car charger is often plugged and unplugged, which is likely to cause this electrode shrapnel and the car. The poor connection of the cigarette lighter socket results in the quality of the USB connector connected to the electronic product; furthermore, the inner side of the electrode shrapnel at both ends of the cigarette lighter plug occupies part of the space inside the cigarette lighter plug, such a design will reduce the car charger Space for the layout of internal parts, and those to be improved.

The creator has accumulated many years of experience in this industry. After long-term careful experiment and research, in the spirit of perseverance, he has finally created a USB power socket, which can eliminate the shortcomings of conventional products and improve efficiency.

The reason is that the main purpose of this creation is to provide a USB power outlet, which is a An innovative USB power socket, the negative electrode system is hexagonal cylindrical and protrudes outside the cigarette lighter plug. The protruding ring of the electrode body is in contact with the housing to conduct the negative power supply. When the cigarette lighter plug is inserted into the car point In the smoke socket, in addition to the occurrence of poor contact, the metal negative electrode body replaces the outside of the cigarette lighter plug made of the conventional plastic shell. The USB power socket product has a good high temperature heat dissipation effect; Since the negative electrode body is completely exposed outside the cigarette lighter plug, the space occupied by the conventional negative electrode shrapnel is reduced inside the cigarette lighter plug, so the layout space of the internal parts of the USB power socket can be increased.

In order to achieve the above-mentioned purposes, this creation uses the following technical means:

A USB power socket, including:

A shell with a perforation in the center and a card slot at one end;

One head seat, with a perforation through the shell, and a perforation in the center;

An electrode body, which protrudes beyond the perforation of the shell, and a convex ring at one end is positioned inside the perforation of the shell, and has a perforation in the center;

An inner sleeve, which is inserted into the perforation of the electrode body, and the convex ring at one end of the inner sleeve is positioned inside the perforation of the outer shell, with a perforation in the center;

A conductive cover, the center cover of the center cover is placed at the end of the head;

A center electrode, one end protrudes out of the perforation of the head seat, and the protruding ring at one end of the center electrode is positioned inside the perforation of the head seat;

A conductive hook, the conductive part of one end extends into the center electrode, and the other end has a hook part;

A spring, one end is sleeved on the outer edge of the conductive hook and extends into the center electrode synchronously with the conductive hook;

A circuit board, a bump at one end is penetrated at the other end of the spring, a hook hole on the inner side of the bump is used for fixing the hook portion of the conductive hook, and a power module is installed at the other end of the circuit board;

A plug-in component, sleeved on the other end of the perforation of the housing; and

An outer cover is provided with a perforation sleeve at one end outside the plug-in component, and a snap ring at one end is fixed in a snap slot of the housing for positioning.
