Description

201203709 VI. [0001] [0003] [0004] [Technical Field] The present invention relates to an electrical connector, and more particularly to an electrical connector that can be applied to a variety of different plug connectors. [Prior Art] Different electronic devices are usually connected by signal transmission lines to transmit signals to each other. Currently, the signal transmission lines and electronic devices are mostly detachably connected by connectors on one end of the transmission line and connector sockets on the electronic device. To connect. Digital cameras, mobile phones, MP3s and other electronic products today's most popular signal transmission specifications than the universal serial bus (USB, Universal to "Bus", the micro connector socket and transmission line made by this specification can reduce the occupation of digital cameras The size of electronic products such as mobile phones and MP3s is convenient for consumers to carry and use. Currently, the commonly used miniature universal serial bus (MlCr〇USB) specifications are mostly 2. 0 versions, and the transmission value of the reference parameters can reach 48 〇 Mbps ° . V.+ π. . However, the amount of software data for electronic products such as digital cameras, mobile phones, and MPFs is constantly rising. S knows that USB 2.0 is gradually eroding the demand for high-traffic data transmission. China Electronic Video Industry Association 2〇 On April 29, 9th, a new signal transmission specification was announced: DiiVA (DiiVA Digital In_ terface for Video and Audio), the signal transmission value can reach above 10 Gbps, which is enough to meet the needs of high-traffic data transmission. The Mini DiiVA plug and socket connector (such as the Chinese utility model patent published on February 3, 2010) is specially designed for digital cameras, mobile phones, MP3 and other electronic products. Designed, 099123054 Form No. A0101 Page 4 / Total 48 Page 0992040628-0 201203709 To accommodate the miniaturization of the product. [0005] 惟 Only the above Micro USB and Mini DiiVA interface are not compatible, the connector of the two The socket and the plug are quite similar, and the short-term internal port is still widely used in various electronic products without disappearing. Due to the demand of high-traffic transmission, future digital cameras, mobile phones, MP3 and other electronic celebrations will also be included in the Mini DiiVA. Connector sockets, in the near future, digital cameras, mobile phones, MP3s and other electronic products will have both connector sockets of the above two specifications. However, the connector sockets of the above two interfaces are bound to increase electronic products. The size is not suitable for the development of miniaturization of electronic products; therefore, some people try to set the Micro USB and Mini Di iVA connector sockets side by side in the same housing. That is, the housing includes two sets of terminals. And two fixing seats, however, the combination means that the thickness of the entire connector socket is increased, thereby making the electronic product of the connector socket Increases, is not conducive to miniaturization of electronic products and inconvenient to carry; both methods are required as a connector receptacle provided increased, inevitably resulting in an increase in manufacturing cost.

.V 〇[0006] Of course, some people try to set the terminals of the two connector sockets to the same socket, for example, the two sets of terminals on the two connectors are respectively disposed on the sides of the tongue on the same socket, and A accommodating space for accommodating two kinds of mating plug connectors is respectively disposed on both sides of the tongue plate; however, for each of the Micro USB and Mini DiiVA connector sockets which are provided with only one row of terminals and the socket itself is small, a row of terminals must be added. To increase the thickness of the tongue plate, it is not possible to match the standard mating plug connector; if the row of terminals is added without increasing the thickness of the tongue, it will inevitably make the tongue plate thinner at the slot receiving terminal. It is easy to break; and the tongue 099123054 Form No. A0101 Page 5 / Total 48 Page 0992040628-0 201203709 After the accommodating space is set on both sides, the thickness of the connector socket is also increased, and when used, Micro USB or Mini DiiVA The upper side or the lower side of a plug connector is not restricted and is easy to shake and fall off. also,

The number of terminals of the Mini DiiVA connector socket is larger than that of the Micro USB connection 3| The number of terminals on the socket is 'and the tongue of the Mini DiiVA connector socket is wider than the tongue of the Micro USB connector socket; thus, the Mini Di iVA cannot be connected The conductive terminals on the socket are set to the tongue of the shorter Mi_cr〇USB connector socket; when the terminal on the Micro USB connector socket is set to the tongue of the Mini DiiVA connector socket, 'connected by Mini DiiVA The socket of the socket is wide and cannot be connected to a standard Micro USB connector plug. [0009] [0009] 099123054 Therefore, it is necessary to modify conventional electrical connectors to overcome the above drawbacks.
