Detailed ways:

The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

First, as shown in Figures 1 to 4, the female seat 1 of the USB3.0+eSATA connector of the present invention is composed of an external metal frame and an internal plastic body, and a cavity is formed on both sides of the metal frame and the plastic body , the cavity is formed by a plastic main body to form a terminal receiving seat 10; as shown in Figure 1, the lower surface of the terminal receiving seat 10 of the female seat 1 is provided with a USB3.0 terminal 11, and the upper surface is provided with an eSATA terminal 12, combined with the figure As shown in 2, 3, and 4, the 4pin terminal 111 of the USB3.0 terminal 11 is set in the concave surface 101 of the terminal receiving seat 10, and the 5pin terminal 112 is set on the plastic ribs on both sides of the concave surface 101 In 102, that is, the main axes of the 4pin terminal 111 and the 5pin terminal 112 of the USB3.0 terminal 11 are located in the same plane, and the terminals are arranged in a mutual offset interval.

According to industry specifications, the size and spacing of the front ends of the terminals of various connectors have certain standards. Since the terminals of the utility model USB3.0 adopt a staggered arrangement on the same plane, if the overall size meets the standard, if the In the prior art, it is obviously impossible to directly arrange the sizes of the terminals of the USB3.0 connector. Therefore, the utility model makes the following improvements. The terminal body of the 5pin terminal 112 of the USB3.0 terminal 11 in the female seat 1 is narrower than the front contact surface, and The axes of the front ends are arranged at equal intervals, and the distance from the main axes of the two outermost terminals to the main axes of the two outer terminals is larger than the distance from the main axes of the two outer terminals to the main axis of the middle terminal. That is, under the condition that the overall peripheral size of the 5pin terminal 112 and the front end meet the standard, the width of the main body of each terminal is reduced, thereby expanding the distance between the terminals, and obtaining enough space to set the 4pin terminal 111, as shown in Figure 2 It shows that the distance x from the main axis of the two outermost terminals to the main axis of the two outer terminals is 2.5 mm, and the distance y from the main axis of the two outer terminals to the main axis of the middle terminal is 2.0 mm.

As shown in Figures 5-8, according to the structure of the above-mentioned female seat 1, the lower inner wall of the cavity (20) of the male head 2 is provided with a USB3.0 terminal 11' corresponding to the female seat 1, and an eSATA terminal is arranged inside 12', the main axes of the 4pin terminal 111' and the 5pin terminal 112' of the USB3.0 terminal 11' are also located in the same plane, and the terminals are also arranged in a mutual misalignment interval, and its structural principle is the same as that of the female seat 1 Corresponding, so no more details.

In addition, the utility model also makes the following improvements:

The front end of the 5pin terminal 112 of the USB3.0 terminal 11 of the female seat 1 has a bent part 1120 embedded in the terminal receiving seat 10. In this embodiment, the USB3.0 terminal 11 is installed by injection molding, that is, After the terminal is placed in the mold, the terminal receiving seat 10 and the USB3.0 terminal 11 are fixed and formed by injection molding. Therefore, the bent part 1120 of the 5pin terminal 112 is directly embedded in the terminal receiving seat 10, which can prevent the terminal from lifting and make the connector more convenient to use. Stablize.

Power terminals 13 are provided on the inner walls of both sides of the cavity of the female seat 1, and a detection terminal 14 is provided on one side, and the front end of the power terminal 13 is in the shape of a hook; corresponding to the two outer sides of the male head 2 The wall is also provided with a power terminal 13'; the hook-shaped power terminal 13 can make the contact between the power terminals less prone to fatigue and have better stability.

In summary, after the utility model adopts the above structure, the 9 terminals of USB3.0 are arranged in the same plane and mutually misplaced, so they can be installed on the same side surface of the terminal receiving seat, while the other side surface is used for installing eSATA terminals , so as to truly achieve both USB3.0 and eSATA connectors.
