Car power adapter

The utility model provides a power adapter for a vehicle, in particular to a vehicle power adapter with simple structure, low manufacturing cost and high stability in use.

According to the continuous development of electronic products, the development of electrical connectors has also been promoted, and various electrical connectors have appeared, such as plugs for household 110 volt plugs or plugs for vehicle chargers, etc. Power supply is turned on, and the general electronic device must be equipped with a power transmission line to electrically connect with a home 110 volt outlet or a car charger. However, the general power transmission line is a connector specification specially designed for use with a single electronic device. When the electronic device of another connector of different specifications is to be charged, since it cannot match the specification of the power transmission line and cannot be charged, it is necessary to additionally find another power transmission line that conforms to the connector of the electronic device, provided that When carrying a power transmission line that conforms to the connector of each electronic device, a complicated messy carrying problem may occur.

Fortunately, there are still the most frequently used connector specifications on the market, namely the universal serial bus USB, and each electronic product is usually equipped with a dedicated connector and a universal serial bus, so how easy it will be The conversion of the car's charger to the universal serial bus USB has become the focus of development.

However, when the general vehicle adapter is used, the following problems and defects are still needed to be improved:

First, the adapter is only used for a single device, and the convenience is insufficient.

Second, the adapter ends are extended by a lengthy wire, and the appearance is messy.

Third, when connecting other electronic devices, it is easy to shake.

Therefore, how to solve the above problems and deficiencies in the past, that is, the applicants of the new type and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, in view of the above-mentioned shortcomings, the applicants of this new type have collected relevant information, and through multi-party evaluation and consideration, and through years of experience in the industry, through continuous trial and modification, they have designed such a simple structure and manufacturing cost. A new patented vehicle power adapter that is low, easy to use and has a stable connection.

The main purpose of the present invention is to make a connection between the positive electric contact portion and the negative electric conductive contact portion which are relatively easy to manufacture and the vehicle power supply base, and convert it into a power output unit common to most electronic devices through the circuit substrate, and support the same. The part improves the stability during use and reduces the shaking of the adapter housing.

In order to achieve the above object, the structure of the present invention comprises: an adapter housing, a circuit substrate disposed in the adapter housing, a positive electrical contact portion electrically connected to the circuit substrate, and at least one electrically coupled to the circuit substrate a negatively-connected negative conductive contact portion, at least one power output portion electrically connected to the circuit substrate, and at least one support portion disposed on the adapter housing; the user connects the new type to the vehicle power supply base When the adapter housing is inserted into the power socket through the support portion, the switch housing is not swayed, and the circuit substrate disposed in the adapter housing is electrically connected with the positive electrical contact portion and the negative electrical contact portion for turning on the power supply. The socket is connected to the power output of the general-purpose serial busbar common to general electronic equipment, and there is no extra wire, which is more convenient to use.

With the above technology, the above-mentioned advantages can be achieved by solving the problem that the conventional vehicle adapter has a complicated structure, a high manufacturing cost, a single function of the adapter, insufficient applicability, and easy shaking during use. Practical and progressive.
