Description

Electric connector

Technical field

The utility model is about a kind of electric connector, refers to especially a kind of electric connector that can be applied to USB3.0 specification.

Background technology

Along with people becoming clear day by day for the convenient application demand of electronic product, and then cause giving more sustained attention of each manufacturer, because each manufacturer is in order to improve the competitiveness of electronic product, therefore must constantly strengthen and expand the function of electronic product, therefore various electronic product is except the external form development towards compact, its structure and transmission speed also need continuous increase, use user is provided the convenience on operation is used.

Because electric connector is for the signal transmission between each element between connecting electronic product or in electronic product, therefore the importance of electric connector on electronic product can not speech, how each manufacturer is easy to electric connector assembling when manufacturing, reduce assembly cost, simultaneously can take into account the effect of electric connector again, become and between each manufacturer, in succession competed part.

In electric connector, in USB connector, also there is maximum breakthrough, USB (Universal Serial Bus) universal serial bus, it is a serial bar standard that connects external equipment, use on computers extensively, it is the most general specification, also can be used on Set Top Box and game machine, even many industrial instrumentations are to be also connected with computer by USB, USB not only can provide peripheral equipment data transmission, also can power, the characteristic of On-The-Go plug and play more can make the direct swap data of portable device.

From the beginning first of USB is USB1.0 specification, its transmission speed is 1.5Mb/s, and in release USB2.0 specification in 1998, transmission speed rises to 12Mb/s, and this specification has been widely used in electronic product, the USB3.0 specification of current up-to-date release more rises to transmission speed 5.0Gb/s, and it is the more than 10 times of USB2.0 specification, therefore because speed promoted manyly more in the past, become the following product of promoting of each manufacturer.

Therefore, in the situation that USB3.0 specification product future can the phase, how USB3.0 product is reached to the object of simple and easy manufacture, more become each manufacturer and need the problem overcoming badly, more because its required splicing ear quantity of specification product of USB3.0 is more, the weld strength when electric connector welding that therefore how to increase USB3.0 is fixed on the circuit board of electronic product, also for needing at present one of problem overcoming badly.

Continue, referring to TaiWan, China utility model patent, to announce M387417 patent be to disclose a kind of USB connector, and it comprises: a substrate, has several the first contact pads and several the second contact pad exposes to this substrate on it; And a connector, it has several flutings and several terminals, and wherein one end of several terminals is placed through respectively in these several flutings and exposes to this fluting, and the other end of this several terminals contacts to form a USB connector with this second contact pad respectively.

Referring to TaiWan, China utility model patent, to announce M412498 patent be to disclose a kind of USB connector again, it includes: a connector body, it has several flutings, several the first terminals and several the second terminal, wherein, between every two flutings, there is a groove post separately, extend forward after being placed in respectively the below of these several groove posts and exposing to these several groove posts one end of these several the first terminals again, the other end extends to horizontal direction after bending downwards respectively again, to form a welding ends, one end of these several the second terminals is placed through respectively in these several flutings and exposes to this fluting, the other end extends to horizontal direction after bending downwards respectively again, to form a welding ends, an and substrate, on it, there is several the first contact pads and several the second contact pad, and these several first contact pads and several the second contact pad are interconnected, to couple for these several the first terminals and this several the second terminals respectively, to form a USB connector.

Though the terminal of only above-mentioned USB connector can provide use in electrical contact, but terminal is to be all fixed on circuit board by welding manner, needs again to re-start welding after tip-off again, causes the inconvenience in manufacture process, more may increase manufacturing cost simultaneously.

As can be seen here, above-mentioned existing structure still has many disappearances, a real non-kindhearted designer, and urgently improved.
