Description

Adapter for connector

The present invention relates to a connector structure, and in particular to a connector adapter.

The most common connectors on the market today are Universal Serial Bus (USB) connectors. Generally speaking, USB Type-A is the most widely used and most popular USB interface. However, USB Type-C is mainly used in thinner and slimmer electronic devices, so USB Type-C is gradually replacing various traditional connectors.

However, as electronic devices are designed to be light, thin, short, and small, the peripheral position and thickness of the body are insufficient, and the internal circuit layout space is insufficient. Therefore, it is impossible to install various electrical connectors in the limited space of the electronic device, resulting in Those who are limited by the specifications of the electrical connector feel inconvenient.

In view of this, the inventor of the present invention aimed at the above-mentioned prior art, devoted himself to research and combined with the application of theories, and tried his best to solve the above-mentioned problems, which became the goal of the inventor's development.

The present invention provides a connector adapter, which uses one end of the connector adapter to be designed to meet the USB Type-C specification and the other end to be designed to meet the USB Type-A specification, so that the existing USB Type-A electrical connector can be transformed It can be used as a USB Type-C electrical connector.

In an embodiment of the present invention, the present invention provides an adapter for a connector, including: a housing, a first socket and a second socket are respectively provided at both ends, and the centerline of the diameter and height of the first socket is the same as that of the second socket. The centerlines of the diameters and heights of the two sockets are offset from each other; and a circuit board is accommodated inside the housing and is fixed to the housing with a concave-convex structure. The two ends of the circuit board respectively have a first tongue plate and a second tongue plate, the first tongue plate has a plurality of first terminals, the second tongue plate has a plurality of second terminals, the upper surface of the first tongue plate is on the same level as the upper surface of the second tongue plate, The first tongue plate is located in the middle of the first socket, the first tongue plate and the plurality of first terminals conform to the USB Type-C specification, the second tongue plate is located at the lower edge of the second socket, and the second tongue plate is located at the lower edge of the second socket. The tongue plate is superimposed on the housing to form a superimposed structure, and the superimposed structure and the plurality of second terminals conform to the USB Type-A specification; wherein, the plurality of second terminals are arranged on the second tongue plate On the upper surface, the number of the plurality of second terminals is nine and conforms to the USB 3.0 Type-A specification, and the ends of five of the plurality of second terminals are above the upper surface and form a distance from the upper surface.

Based on the above, the first tongue plate and the plurality of first terminals of the circuit board conform to the USB Type-C specification, but the first tongue plate and the second tongue plate are part of the same circuit board, so the thickness of the second tongue plate also conforms to the USB Type-C specification. The Type-C specification does not conform to the USB Type-A specification, so the centerline of the diameter and height of the first socket and the centerline of the diameter and height of the second socket are misaligned, and then the second tongue plate is superimposed on the second shell The thickness of the second tongue plate is increased so that the second tongue plate and the second shell jointly form a superimposed structure, and the superimposed structure and the plurality of second terminals comply with the USB Type-A specification.
