Description

an electrical connector

technical field

The utility model relates to the field of electric connection, in particular to an electric connector.

Background technique

With the advancement of the technology era and the development and prevalence of computer technology, more and more functions and additional functions are provided for users to use conveniently, and relatively make users' desire for performance stronger. Manufacturing from various manufacturers It can be seen that the clock pulse of the processor and memory is constantly increasing, and the speed of the hard disk and optical disk is advancing with the times. Therefore, the emergence of new specifications and new technologies in almost every electronic technology product is to solve the problem of transmission speed. As for the hard disk interface and other storage devices, PATA (that is, the IDE parallel transmission interface we are familiar with), which first appeared in the home market, has a bottleneck as the speed increases, and PATA100 or PATA133 is its physical characteristic. Of course, it is not impossible to push upwards, but the cost and performance will not be directly proportional, so that the characteristics of high quality and low price in parallel signal transmission will completely disappear, so the SATA standard will be introduced.

However, in addition to the bandwidth problem of the internal interface, the impact is actually more difficult on the external transmission interface, because whether it is USB2.0 or the common IEEE1394, although it has good scalability and universality, It is also a very popular external interface at present, but it is not enough in terms of transmission bandwidth, so the so-called eSATA interface (External Serial ATA, eSATA) appears, and since the eSATA specification is completed, It is mainly used as an electronic device such as a hard disk that requires high transmission bandwidth. In addition to data backup and protection, eSATA has better performance, especially for external DV audio-visual applications that require high bandwidth and low-cost storage. It can be regarded as a very good help; however, when the eSATA connector is used in general, the power plug must be used to supply the power required by the eSATA connector, which also causes many defects in the use of the eSATA connector, such as:

(1) The currently used eSATA connectors must be equipped with a power connector, and must be plugged in at the same time to transmit data, otherwise the data cannot be transmitted, which is inconvenient to use.

(2) On the circuit board where the eSATA connector is installed, the power connector must be installed again, which will also occupy the space on the circuit board and affect the circuit layout of the circuit board.

Contents of the invention
