Description

Connector combination structure

The invention provides a combined structure of connectors, in particular to a combined structure of connectors with excellent high-frequency signals.

According to the high-frequency signal transmission environment, if the relevant electrical condition parameters are not properly utilized in the design, so that they can be bounded within the standard range, then the physical products may operate due to electrical signals. The transmission is subject to interference from multiple noises, resulting in poor transmission efficiency. Among them, the most important condition parameter existing in the connector terminal is the impedance value, which is the key to the whole electrical signal transmission effect, such as material impedance, characteristic impedance, transmission line and connector differential mode. Impedance, common mode mode impedance, etc., can cause electrical signal transmission to be disturbed, such as: Insertion Loss, Crosstalk, Return Loss, etc.

At present, in order to improve the above-mentioned interference and loss problems, we start with the material part. However, when we design the double-row cable connector, we find that the change and adjustment of the impedance value will cause the above insertion loss (Insertion). Loss), crosstalk, and return loss. In other words, if the terminal arrangement of the double-row cable connector can be used to control the quality of the high-frequency signal transmission, the above problem can be easily solved.

However, when the terminals of the above-mentioned double-row cable connector are arranged in use, the following problems and defects are still to be improved: most of the high-frequency signal terminals are arranged with the terminals of the grounding, power supply, and low-frequency signals, so that the two rows of terminals are When extending to the inside of the cable, the two rows of terminals are staggered. In addition, the high-frequency terminals cannot be coupled, and the grounding, power supply and other terminals cannot be used to form a barrier, so that the high-frequency signals do not perform well.

Therefore, how to solve the above problems and deficiencies in the above-mentioned applications, that is, the inventors of the present invention and those involved in the industry are eager to study the direction of improvement.

Therefore, in view of the above-mentioned deficiencies, the inventors of the present invention have collected relevant information, and have evaluated and considered such high-frequency signals through continuous trial and modification through multi-party evaluation and consideration.
