## Title
Compound connector plug

## Abstract

A compound connector plug is disclosed in the present invention. It has a first fixing device for fixing a first terminal set and a second terminal set, and a second fixing device for fixing a third terminal set. The first terminal set has an improved shape so that the compound connector plug can be easily produced. The two devices are connected together and enclosed by a casing. Each terminal set or the combination of terminal sets can support transmission standards, such as eSATA, USB2.0 and USB3.0. An all-in-one connector plug is provided so that no adaptor is needed if a user uses the connector for different kinds of sockets.

## Background
FIELD OF THE INVENTION
The invention relates to a compound connector plug, and more particularly, to a compound connector plug compatible with both Universal Serial Bus (USB 2.0 and USB 3.0) standards and External Serial Advanced Technology Attachment (eSATA) standards.
BACKGROUND OF THE INVENTION
The remarkable development of computer equipments has been seen as technology evolved over the years. It is always the target for all manufacturers to create devices for faster and more efficient data transmission. However, replacement of an existing standard with a new one involves not only the industrial technique, but also user who uses related products. The latter dominates since all users tend to keep using current products until they are not workable anymore.
Demands of the market for more compact electronic products are growing. In addition to reducing size of each internal element inside a device, external sockets or plugs need to be unified or modified. Otherwise, only necessary sockets and plugs are adopted to be used in the limited external area of the device. Inevitably, there is a gap existing between reality and expectation. For many peripheral or connected electronic products, how to solve the problem of incompatibility due to diverse connectors becomes a primary issue. Therefore, a compound connector plug compatible with multiple standards is required to solve the afore-mentioned problems. Meanwhile, application of such compound connector plugs can significantly reduce the space occupied.
External Serial Advanced Technology Attachment (eSATA) and Universal Serial Bus (USB) are two kinds of commonly used standards for connectors. Because the size of connector of the eSATA standard is similar to that of the USB standard, the two connectors can be devised to share one compound connector plug. FIG. 1 discloses a compound connector plug of Taiwanese Utility Model M369570. The invention comprises a housing with a slot. A first terminal set having a number of eSATA terminals and a second terminal set having a plurality of USB terminals are installed in the slot. The first and the second terminal sets are compatible with eSATA standards and USB 3.0 standards, respectively.
In mass production, the connector plug of the above prior art is inserted to USB terminals by ways of Insert Molding, and the hook tip 1 will be snagged with plastic injection hole 2 for USB 3.0, which will cause defective products and slow production. Therefore, the inventor creates a connector plug compatible with both eSATA and USB 3.0 standards based on the demands of related industrials.
