Description

USB male connector

Technical field

The relevant a kind of connector of the utility model refers in particular to a kind of USB male 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, USB1.1 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 male 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 similar face or 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 male 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 male connector, comprising: insulating body offers groove and is positioned at two or more terminal grooves of this groove upper limb; Circuit board, this groove of cross-under also has opposite first and second surface, the front end of this first surface is laid with two or more golden fingers, the rear end of this second surface is laid with two or more golden fingers, and this golden finger on this first surface electrically connects this golden finger on this second surface; 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 of this first surface.

Compared with prior art, USB male connector of the present utility model has following effect: because the utility model is directly laid two or more golden fingers to replace known four conducting terminals on circuit board, and insulating body does not need to extend hyoplastron connecting nine conducting terminals, therefore can significantly simplify the structure of male 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.

Embodiment

Relevant detailed description of the present utility model and technology contents are described as follows conjunction with figs., yet appended accompanying drawing usefulness as an illustration only is not to be used to limit the utility model.

At first, mentioned in the following description " the place ahead " and " rear " are to be defined as the place ahead according to the direction of insertion that USB male connector desire is inserted corresponding female connector, and the direction opposite with direction of insertion then is the rear.

Please refer to Fig. 1, perspective exploded view for USB male connector of the present utility model, the utility model provides a kind of USB male connector (hereinafter to be referred as the male connector), and this male connector 1 mainly comprises insulating body 10, circuit board 20, two or more conducting terminals 30 and metal shell 40.

Insulating body 10 is to be made by insulating material such as plastic cement or resins, and insulating body 10 has body 11 and extends stop section 12 from body 11 rear ends; Stop section 12 offers groove 121 and is positioned at two or more terminal grooves 122 at groove 121 upper limb places, and groove 121 wears this stop section 12, and the quantity of terminal groove 122 is five, and terminal groove 122 runs through stop section 12 and body 11.

Circuit board 20 is slim printed circuit board (PCB), and its width is substantially equal to the width of the groove 121 of insulating body 10, therefore, but circuit board 20 cross-under grooves 121; Circuit board 20 has opposite first 21 and second surface 22, and in embodiment of the present utility model, as shown in Figure 1, first surface 21 is meant the upper surface of circuit board 20, and second surface 22 is meant the lower surface of circuit board 20; The front end of first surface 21 is laid with two or more golden fingers 211, these golden fingers 211 be with Copper Foil conduction material forming on first surface 21 and its quantity be four; Similarly, the rear end of second surface 22 is laid with two or more golden fingers 221, these golden fingers 221 be with Copper Foil conduction material forming on second surface 22 and its quantity be four; And, be noted that especially four golden fingers 211 on the first surface 21 electrically connect four golden fingers 221 on the second surface 22 respectively.
