The invention relates to a receptacle connector, and more particularly, a receptacle connector complies with USB 2.0 and USB 3.0 specifications.
A Universal Serial Bus (USB) is a hot-swap type transmission interface widely used in computer peripherals, connects to hardware to a computer and transmits information without rebooting the computer. In 1998, a USB 1.1 transmission interface was first released. In 2007, Intel Corp. released a USB 2.0 transmission interface allowing the USB interface to be used with more applications including flash drives, printers and mice and having a transmission rate of 480 Mbps, about 40× times faster than the USB 1.1 interface.
As computers have become increasingly powerful and able to process larger amounts of data, computers and computer peripherals have had to be able to transfer more and more data. Transmission efficiency of a USB 2.0 interface is limited by file size that has promoted development of a USB 3.0 interface. The USB 3.0 interface has all the capabilities of the USB 2.0 interface but has more advantages such as lower power consumption and higher transmission rate.
The objective of the present invention is to provide a receptacle connector complies with USB 2.0 and USB 3.0 specifications and provides stable transmission at high transmission rates.
A receptacle connector in accordance with the present invention incorporates USB 2.0 and USB 3.0 interface capabilities and comprises an insulated housing, five first contact pins, four second contact pins and a metal casing. The first pin complies with a USB 3.0 interface standard, comprises a contact, a connected portion, a second pin and an arch and mounts parallel to the first terminal on the insulated housing. The second contact pins complies with a USB 2.0 interface standard, comprises a protruded end, an elongated portion and a first pin mounted on the insulated housing. The metal casing mounts around the insulated housing. The receptacle connector transmits data steady at a high rate.

The mounting holes (11121) are formed in the distal edge of the transverse protrusion (1112).
The second contact pin holes (11122) are parallel to the longitudinal body (1111).
The locking notches (11123) are formed respectively on the sides of the transverse protrusion (1112).
The alignment notches (11124) are formed on the transverse protrusion (1112) opposite to the mounting holes (11121).
The inner surface of the upper housing (111) has plural parallel grooves (11111) and plural parallel channels (11112).
The lower housing (112) is connected to the upper housing (111) and comprises a longitudinal body (1121) and a transverse protrusion (1122). The longitudinal body (1121) has an inner surface, is provided with plural first holes (11211), second holes (11212) and an abutting element (11213). The abutting element (11213) mounts on the surface and corresponds to the abutting holes (11121) of the upper housing (111). The transverse protrusion (1122) is formed on the surface of the longitudinal body (1121) and comprises plural terminal passages (11221). The terminal passages (11221) are connected to the second holes (11211) and the second holes (11212).
The first terminal (12) complies with a USB 3.0 interface, comprises a protruded end (121), an elongated portion (122) and a first pin (123) and is insert-molded in the upper housing (111). The protruded end (121) mounts on the grooves (11111) of the upper housing (111). The elongated portion (122) is connected to the protruded end (121), narrower than the protruded end (121) and is embedded in the longitudinal body (1111) of the upper housing (111). The first pin (123) is longitudinal to the elongated portion (122) and passes through the first holes (11211) and the terminal passages (11221).
The second terminal (13) complies with a USB 2.0 interface and comprises a contact (131), a connected portion (132), a second pin (133) and an arch (134), and is insert-molded in the upper housing (111). The connected portion (132) elongates from the contact (131). The second pin (133) is longitudinal from the connected portion (132) and passes through the second holes (11212) and the terminal passages (11221). The arch (134) could reduce an external force resulting from plugging in a plug connector to lower the flexibility of the second terminal (13).
