Electric connector for transmitting power and signal

This creation is about an electrical connector, especially an electrical connector used for charging and capable of transmitting power and signals.

Electric vehicles have become the hottest industry in recent years due to energy and environmental protection issues, which have jointly promoted the research and development of related technologies. The important key to the normal operation of electric vehicles obviously comes from electricity, and electricity comes from the on-board battery of the electric vehicle and related devices and facilities for charging the battery.

On the issue of charging, the battery of an electric vehicle is connected through an intermediary device and a device that provides charging (such as a charging pile). The intermediary device is usually a connector through which the charging device is connected to the battery of the electric vehicle. Charge the battery. The traditional charging process is a simple power supply process. However, with the increase in the power of the charging power supply and many considerations such as efficiency and safety, charging is not only the supply of electricity. In addition to power supply, it also involves the detection of various states and parameters. And monitoring, which means that there will be corresponding monitoring signals generated before, during, and after charging.

The integration of power supply and signal transmission interfaces on the above-mentioned connectors is a reasonable and inevitable design. However, although the power and monitoring signals are transmitted on the same medium, after all, the power and monitoring signals are completely different energy types, and interference may even occur during simultaneous transmission; It can be seen that it is imperative to integrate power and signal transmission on the connector, but it is still necessary to consider that power and signal transmission can operate at the same time without interfering with each other in order to meet actual needs.

Therefore, the main purpose of this creation is to provide an electrical connector for transmitting power and signals. Through space planning and distinction of energy types, the electrical connector can ensure normal electrical characteristics and avoid interference when transmitting power and signals.

The main technical means adopted to achieve the aforementioned purpose is to make the electrical connector for transmitting power and signal include: A connector base having a connecting portion, and the surface of the connecting portion is divided into a first area and a second area according to space; A pair of electrical connection terminals includes a first electrical connection terminal and a second electrical connection terminal. The first electrical connection terminal and the second electrical connection terminal are arranged on the connection part of the connector base and located in the first area of the connector base. ； A plurality of signal terminals are arranged on the connection part of the connector base and located in the second area of the connector base; among them, there is a first connection terminal between more than one signal terminal and the first electrical connection terminal among the plurality of signal terminals. For a distance, there is a second distance between more than one signal terminal of the plurality of signal terminals and the second electrical connection terminal, and the second distance is greater than the first distance.

The above-mentioned electrical connector is to plan the electrical terminals and signal terminals in different areas on the connection part, and further consider the full use of space, so that each signal terminal is different from the first and second electrical terminals due to their different signal types. In this way, it can take into account the use of space, but also ensure the electrical characteristics and compliance with various safety requirements such as withstand voltage test and insulation resistance test.

The slot chamber 31 and the connecting portion 32 have corresponding geometric shapes. In this embodiment, the slot chamber 31 is connected to The portions 32 are all circular, and the connecting portion 32 extends coaxially from the bottom of the tank chamber 31 upwards. There is a gap between the diameter wall of the connecting portion 32 and the inner tank wall of the tank chamber 31 to form a ring groove.

Please refer to FIGS. 2 and 3, the connecting portion 32 has a surface, and a first area 321 and a second area 322 are formed according to the space of the surface. The first and second electrical connection terminals 10, 20 are It is arranged on the connecting portion 32 and located in the first area 321 thereof, and each signal terminal 41 to 47 is also arranged on the connecting portion 32 and located in the second area 322 thereof. In this embodiment, the connecting portion 32 is circular, and is divided into a first area 321 and a second area 322 equally divided by 180 degrees. Taking the direction shown in FIG. 3 as an example, 90 degrees to more than 270 degrees The semicircular range of is the first zone 321, and the other relative semicircular range of 90 degrees to less than 270 degrees is the second zone 322. It must be particularly noted that the aforementioned connecting portion 32 is circular, and the first area 321 and the second area 322 are formed by symmetrical semicircular ranges. This is only an example and not an inevitable shape during implementation. It is hereby declared.

In this embodiment, the first electrical connection terminal 10 is a negative power supply terminal, and the second electrical connection terminal 20 is a positive power supply terminal. In order to meet the electrical connector's safety test requirements such as withstand voltage and insulation resistance, the first electrical connection terminal 10 Maintain a relatively large distance from the second electrical connection terminal 20 in the first area 321. Specifically, the distance between the first electrical connection terminal 10 and the second electrical connection terminal 20 is larger than the two phases of the signal terminals 41 to 47 The distance between adjacent signal terminals is also greater than the distance between the first electrical connection terminal 10 or the second electrical connection terminal 20 and any of the signal terminals 41 to 47.

In this embodiment, the connecting portion 32 is provided with a total of 7 signal terminals 41 to 47 in the second area 322.
