Technical field

The relevant a kind of connector of the utility model refers in particular to a kind of USB female connector.

Background technology

USB (USB, Universal Serial Bus) is the most widely used a kind of coffret in the present personal computer peripheral device product, be to advocate initiation at first, up to the present experienced the evolution of three versions such as USB1.0, USB 1.1 and USB2.0 by Intel and Microsoft.USB1.0,1.1,2.0 versions are supported following three kinds of transmission rates respectively: (1) low-speed mode transmission rate is 1.5Mbps; (2) mode transfer speed is 12Mbps at full speed; (3) the fast mode transmission rate is 480Mbps.

Yet,,, therefore, just release the coffret of USB3.0 even the transmission rate of USB2.0 also can not satisfy the demand for development of some electronics industry along with the development of electronics industry.The coffret of USB3.0 is to have at USB2.0 to increase by two groups of differential terminal and an earth terminal on the basis of four butt, therefore has nine butt, thereby makes transmission rate reach the level of 5Gbps.

According to prior art, the female connector that meets the USB3.0 specification mainly comprises insulating body, this insulating body front end extends hyoplastron, and the contact site of five butt that the increase contact site with four butt of original USB2.0 is arranged on respectively on the opposed surface of hyoplastron; Because the position of these terminals is by unified standardization, therefore, five butts that is increased is divided into two rows in vertical direction with four original butt, and all terminals are separated from one another to avoid short circuit.

Yet, march toward day by day gently at computer peripheral equipment commodity and corresponding connector thereof, under thin, short, the little development trend, configuration nine butts increases the degree of difficulty of manufacture craft and assembling really on the hyoplastron of small size like this, also can't make the volume of whole connector further reach slimming.

Therefore, how to solve the above problems a little, promptly become the target that the utility model is improved.

The utility model content

Main purpose of the present utility model is to provide a kind of USB female connector, can simplified structure and dwindle the volume of connector, and to meet the requirement of slimming.

For achieving the above object, the utility model provides a kind of USB female connector, comprising: insulating body offers groove and is positioned at two or more terminal grooves of this groove lower edge; Circuit board, this groove of cross-under also has opposite first and second surface, and the front end of this first surface is laid with two or more golden fingers; Two or more splicing ears, an end are fixed in the rear end of this second surface and electrically connect this golden finger; And two or more conducting terminals, this terminal groove of difference cross-under, the front end of each conducting terminal has junction, and this junction is positioned at this golden finger rear.

Compared with prior art, USB female connector of the present utility model has following effect: be provided with two or more splicing ears that electrically connect with golden finger because the utility model is directly laid two or more golden fingers and its rear end at the front end of circuit board, to replace known five conducting terminals, and, insulating body does not need to extend hyoplastron connecting nine conducting terminals, therefore can significantly simplify the structure of female connector and meet the requirement of slimming; On the other hand, because designs simplification of the present utility model and required number of spare parts reduce, therefore, can reduce manufacturing cost and shorten built-up time.
