Description

Electrical connector (2)

The invention provides an electrical connector, in particular an electrical connector capable of effectively blocking noise interference.

Press, there are quite a variety of electrical connectors, including the so-called most common USB and recently HDMI, but in fact, in the era of information explosion, most people will carry one or even two The smart phone to improve the connection between people and people, and each smart phone has limited space, so the transmission device will be matched with MICRO USB, which can be set in a limited space.

In the past few years, the file of the data stream can be said to be getting bigger and bigger. From photos to movies, it may have been a few KB in the past, up to a few MB. Until now, the file is in the G, in the early general MICRO USB. In terms of speed, it is impossible to digest, which makes it very time consuming to transfer files.

Therefore, some manufacturers have developed the MICRO USB3.0 connector, the speed is generally faster than the general MICRO USB2.0, but although the speed is increased, the volume performance is also reduced, because the MICRO USB3.0 The volume is larger than the MICRO USB2.0. It is inconvenient and less common for general smart phones.

Therefore, the current extension of a USB C TYPE connector that can provide forward and reverse insertion, this connector can not only provide a large current, but also make the smart phone charge faster, and also provide ultra-high-speed transmission rate, so that the current file is on the G It can be said that the transmission can be completed in a short time, but in the running condition, the problem that the terminals interfere with each other often occurs, resulting in too much noise and affecting its overall efficiency.

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, the inventors of the present invention have collected the relevant information in view of the above-mentioned deficiencies, and through multi-party evaluation and consideration, and through years of experience accumulated in the industry, through continuous trial and modification, this design can effectively design the noise.

The three high frequency differential signal conductor pair has a fourth high frequency differential signal conductor pair on the other side. Therefore, when the differential signal conductor pairs and the other signal conductors are operated, the first high frequency differential signal conductor pair and the second high frequency are blocked by the separation of the first shielding spacer and the second shielding spacer. The signal interference of the differential signal conductor pair, the first other signal conductor and the second other signal conductor is separated from the third shielding spacer by the second shielding spacer to block the first other signal conductor, the second The other signal conductor, the first low frequency differential signal conductor pair and the second low frequency differential signal conductor pair interfere with each other, and the third shield spacer and the fourth shield spacer are separated to block the first low frequency differential signal The signal pair, the second low frequency differential signal conductor pair, the third other signal conductor and the fourth other signal conductor interfere with each other, and finally the third shield spacer and the fifth shield spacer are separated to block the third The other signal conductor, the fourth other signal conductor, the third high frequency differential signal conductor pair and the signal of the fourth high frequency differential signal conductor pair interfere with each other.
