Description

Electrical Connector Adapter Board

The invention relates to an adapter board, in particular to an electrical connector adapter board capable of good grounding, carrying high and low currents, and providing an adapter signal for an electronic card connector.

The function of electrical connectors is mainly to transmit electrical signals. In order to transmit signals stably, existing electrical connectors are equipped with shielding members or grounding members, so as to prevent noise interference signals from the outside, such as electrostatic interference (ESD) or electromagnetic interference ( EMI) to a minimum. In particular, with the rapid development of computers at present, the transmission speed of peripheral equipment connected to electrical connectors has increased (so-called high-frequency transmission), and the noise interference between electronic components has increased relatively. In order to reduce the noise interference suffered by various electronic components during transmission , some protective measures have become design issues that must be considered. Related technologies are disclosed in Taiwan Patent Application Nos. 80207449, 81216447, 81217278, 82205600, 83202199, 83107162, 8328140, 77208107, 84213585, 84213586 and 85210940. Regarding the electronic card connector related to the present invention, the product association (PCMCIA) stipulates that a grounding element needs to be provided at a specific position of the connector. Therefore, corresponding Cooperate. Although the existing connector itself is equipped with a shielding component and a grounding component to suppress noise, it is only one of the two sides of the signal transmission. For the main substrate on the other side, of course, the more complete the grounding facility, the better the suppression effect. However, the grounding configuration of the existing main substrate under high-frequency transmission has very limited effect on preventing noise, because under high-frequency transmission, the wiring on the surface of the main substrate and the wiring between the connector module and the module increase, making the The phenomenon of crosstalk between lines increases, and if the current grounding method is used, it is obvious that the effect of suppressing noise is not ideal. Furthermore, the existing main board cannot carry high current loads. The main reason is that the signal sources are in one-to-one correspondence, that is, one jack is connected to one conductive signal line. Therefore, when a specific position in the signal source carries high power supply When the current of the device is high, the original signal line will not be able to load.
