Description

Connector where the grounding terminal and the grounding mid-board are in the same welding area

This book is about connectors, especially a kind of connector where the soldering feet of both the ground terminal and the ground midplane will be in the same soldering area when fixed to the circuit board.

Press, all kinds of electronic devices (such as: smart phones, tablets, desktop computers, notebook computers, digital cameras... etc.) in order to receive electronic signals and power from the outside world, usually must be The body of the device is equipped with a signal connector. Generally speaking, the signal connector (Connector) generally refers to all the connecting components and their accessories used in electronic signals and power supplies. It is a bridge for all signals. Its quality will affect the current and the signal. The reliability of the transmission has an impact and is also closely related to the operation of the electronic device. Moreover, through the function of the signal connector, the plurality of electronic devices can be connected into a complete system, according to which the electronic signal or power supply is transmitted to each other, so it can be known that the signal The connector is an indispensable element for the electronic device to realize a predetermined function.

According to the above, with the development of AR/VR applications and the emergence of 4K/8K displays, high-definition image transmission has gradually become mainstream. Therefore, the original analog interface certainly cannot meet the needs, making DisplayPort (video connector) become Consumer electronics (CE) devices are the preferred interface standard. Among them, in response to modern people's demands for the design of consumer electronics devices, most of them are mainly "light, thin and short", but they want to have both functional demands Various novel functions, therefore, the manufacturer must equip the layout space of each component in the consumer electronic device. It is necessary to compare the baht in order to meet the needs of consumers between appearance and function to improve their competitiveness in the market. This situation has caused the size of DisplayPort to be reduced together to make more available. Space, however, as the size of DisplayPort shrinks, it is bound to make its two sets of signal terminals closer to each other. For high-frequency transmission, it is easy to cause interference between the two sets of signal terminals, which affects the high frequency and high speed of DisplayPort. Transmission efficiency.

In addition, under the situation that the transmission speed of digital signals has been increased to high speed and high frequency, the digital signals transmitted through the signal connectors themselves will also suffer losses during transmission, therefore, the aforementioned losses are minimized, so that Digital signals can obtain stable and accurate transmission quality, which has become an important issue in the development of the high-frequency signal connector industry. Especially for the signal connector, the mechanical structure design is different from the high-frequency electromagnetic power. Sexual design analysis is two very different professional fields, so how to achieve the best balance in engineering design is even more difficult.

Generally speaking, the grounding midplane used in existing connectors can be roughly divided into two cases. The first is that the grounding midplane does not have any soldering legs, and the second is that although the grounding midplane has soldering legs, However, the aforementioned soldering feet are soldered separately on the circuit board and have separate circuits. The above-mentioned conventional situation in use will cause the grounding path between the grounding midplane and the grounding terminal to be too long. Therefore, the applicant is particularly Based on the above two conventional situations, a connector with the ground terminal and the soldering pin of the ground midplane in the same soldering area is designed. With the advent of this creation, the user will be provided with a better experience.

One purpose of this creation is to provide a connector with the ground terminal and the welding pin of the ground midplane in the same welding area, including an insulating body, a first metal terminal group, and a second A metal terminal group and a grounding midplane, wherein the first metal terminal group includes a plurality of first signal terminals and at least one first ground terminal, the first signal terminals and the first ground terminal are provided on the insulation On the body; the second metal terminal group includes a plurality of second signal terminals and at least one second ground terminal, the second signal terminals and the second ground terminal will be provided on the insulating body; It is made of metal, which will be located between the first metal terminal group and the second metal terminal group, and will not be electrically connected to each of the first signal terminals and each of the second signal terminals; features of this creation At least one mid-plate welding pin is provided on the rear end of the ground mid-plate, and each of the mid-plate welding pins will be adjacent to a first ground welding pin of each of the first ground terminals or an adjacent one of each of the second ground terminals The second ground soldering pin, when the connector is fixed to a circuit board, each of the midplane soldering pins will be in the same soldering area on the circuit board as the corresponding first ground soldering pin or the second ground soldering pin In this way, the ground path between the ground midplane and the first/second ground terminals can be effectively shortened, so that the connector has better high-frequency performance.
