Stacked type connector with power supply function

Stacked connector with power supply function

This creation is related to stacking connectors, especially stacking connectors in which two internal connectors are electrically connected to each other.

Nowadays, the electronics industry is developed, and various electronic devices are flooding the life of the general public. In order to input control commands to control the electronic devices, or to transmit data between multiple electronic devices, most of the electronic devices are equipped with motherboards. Multiple connectors.

With more and more peripheral products of electronic devices, the demand for connectors is also increasing. Therefore, there is a trend of more and more connectors configured on a single electronic device. However, if an excessive number of connectors are provided on the electronic device, it will actually occupy valuable configuration space on the motherboard of the electronic device, which makes it difficult to reduce the overall size of the electronic device.

To solve the above-mentioned problems, a stacked connector has appeared on the market, which is mainly based on the area of a single connector, and the connectors with multiple interfaces are stacked in the vertical direction, whereby the vertical space is exchanged for the horizontal space. For the motherboard of an electronic device, using this type of stacked connector can have multiple connectors at a time, but only occupies the area of a single connector. Therefore, it can save a lot of configuration space on the motherboard for other settings. Components, or reduce the area of the motherboard.

However, although multiple connector interfaces are provided on this type of stacked connector at the same time, it is a pity that the connectors cannot be connected to each other, nor can they transmit signals to each other. For example, when a stackable connector has both an RJ-45 connector and a USB connector, even if the RJ-45 connector can support Power over Ethernet (PoE) technology, all It is a pity that the received power cannot be provided to the USB connector for use. Conversely, the USB connector can receive power from the motherboard of the electronic device, but the power received by the USB connector cannot be provided to the RJ-45 connector for use.

In view of this, how to make the existing stack-type connectors be used more efficiently is a topic that practitioners in this field have concentrated on.

The main purpose of this creation is to provide a stackable connector with power supply function, which can be used by the USB connector on it to provide power to the RJ-45 connector on it, or by the RJ-45 connector Provide power to the USB connector, so as to achieve the purpose of mutual power supply.

To achieve the above-mentioned purpose, the stacked connector of the present invention mainly has an insulating body, a plurality of connection terminals and a USB connector. The rear face of the insulating body has a first accommodating space, the front face has a connecting interface and a second accommodating space, and the connecting interface is provided with a plurality of terminal slots communicating with the first accommodating space. The plurality of connection terminals are arranged in the first accommodating space, and are respectively exposed in the connection interface to form an RJ-45 connector. The USB connector is arranged in the second accommodating space. The power pin and the ground pin of the USB connector are respectively electrically connected to the empty pins in the plurality of connection terminals, whereby the USB connector can receive power from the motherboard and supply power to the RJ-45 connector. Furthermore, the RJ-45 connector can also receive power from the outside through PoE technology and supply power to the USB connector.

Compared with the previous technology, the effect of this creation is that the power pin and ground pin of the USB connector are electrically connected to the unused vacant pins of the RJ-45 connector, thereby allowing power to be available. Transfer between the USB connector and the RJ-45 connector. In this way, when the USB connector receives power from the motherboard, it can be provided to the RJ-45 connector, so that the RJ-45 connector can support the use of Power over Ethernet (PoE) technology Network equipment.

Furthermore, if the RJ-45 connector in the stackable connector can support PoE technology, the RJ-45 connector can also receive power from external network equipment and provide it to the USB connector. Use connected hardware devices for power supply or charging.
