This creation relates to stacking connectors, and more particularly to USB stacking connectors.

In order to carry out data and power transmission with an external device, one or more connectors are usually provided on a general electronic device such as a mobile device or a computer. However, the arrangement of these connectors seriously occupies valuable configuration space on the motherboard of the electronic device.

In view of this, a stacked connector has been proposed on the market, mainly stacking two or more connectors together. In this way, the motherboard of the electronic device can set a plurality of connectors only by retaining a configuration space of one connector, thereby achieving space saving.

However, in order to effectively process the signals transmitted by the connectors, the motherboard of the electronic device also needs to set corresponding control circuits for the formats of the connectors. Referring to FIG. 1, a schematic diagram of a prior art stacked connector connection is shown. When a stack connector 2 is to be set on a motherboard 1, in addition to the need to retain the corresponding configuration space, a corresponding control circuit needs to be disposed thereon.

The -C connector is connected so that the chip set 11 can separately process the signal transmitted by the USB Type-A connector and the signal transmitted by the USB Type-C connector.

As can be seen from the above description, although the arrangement of the stack connector 2 can save the configuration space on the motherboard 1, the control circuit to be disposed on the motherboard 1 is not reduced by the setting of the stack connector 2. .

The main purpose of this creation is to provide a USB stacking connector that extracts a set of signals of a different format from a set of USB Type-C signals for use by other connectors on the USB stacking connector.

In order to achieve the above purpose, the USB stack connector of the present invention mainly has a USB Type-C connector, a USB Type-A connector, a multiplexer unit, a plurality of conductive terminals, and an electrical connection of the USB Type-C. a connector, the USB Type-A connector, a circuit board of the multiplexer unit and the plurality of conductive terminals. The USB Type-C connector and the USB Type-A are electrically connected to the multiplexer unit, and the multiplexer unit is connected to an external motherboard through the plurality of lead terminals.

As described above, the USB stack connector transmits a single set of USB Type-C signals to the motherboard through the multiplexer unit, whereby the multiplexer unit can respectively provide a set of upper layer terminal signals according to the USB Type-C signal. And a set of lower layer terminal signals are given to the USB Type-C connector, and a set of USB Type-A signals can be taken out from the USB Type-C signal and provided to the USB Type-A connector.

The current USB Type-C signal is mainly composed of a set of upper layer signals and a group of lower layer signals, wherein the upper layer signal and the lower layer signal respectively contain complete USB Type-A signals. The technical effect achieved by the present invention over the prior art is that a complete set of USB Type-A signals can be taken from a set of USB Type-C signals provided by the motherboard through the setting of the multiplexer unit. Used for other connectors that are stacked with the USB Type-C connector, such as a USB 2.0 Type-A connector or a USB 3.0 Type-A connector. Thereby, the circuit configuration set on the motherboard can be effectively simplified.
