Electric connector

Abstract

The invention provides an electric connector which is applicable to inserted connection of two different plug connectors. The electric connector comprises an insulating body, a plurality of conductive terminals fixedly clamped in the insulating body and a shielding shell covering the insulating body, wherein the insulating body is provided with a base part and a clapper extending forwards from the base part; the conductive terminals are provided with contact parts extending onto the clapper; the shielding shell is provided with a top wall and a bottom wall which are oppositely arranged as well as two side walls connected between the top wall and the bottom wall; the two side walls of the shielding shell have step-like outlines so as to form a first insertion hole corresponding to the outer outline of one plug connector and a second insertion hole corresponding to the outer outline of the other plug connector together with the top wall and the bottom wall; and the first insertion hole and the second insertion hole are partially shared.

Description

【Technical field】 [0001] The invention relates to an electrical connector, in particular to an electrical connector applicable to various plug connectors. 【Background technique】 [0002] Different electronic devices are usually connected by a signal transmission line to transmit signals to each other. Currently, the signal transmission line and the electronic device are mostly detachably connected through a connector on one end of the transmission line and a connector socket on the electronic device. [0003] The most popular signal transmission specification for digital cameras, mobile phones, MP3 and other electronic products is the Universal Serial Bus (USB, Universal Serial Bus). The volume of electronic products such as MP3 is convenient for consumers to carry and use. At present, the commonly used Micro Universal Serial Bus (Micro USB) specification is mostly version 2.0, and the theoretical transmission value can reach 480Mbps. [0004] However, the amount of softwa...

Problems solved by technology

[0005] However, the above-mentioned Micro USB and Mini DiiVA interfaces are not compatible, only the connector sockets and plugs of the two are quite similar, and the USB interface is still widely used in various electronic products in the short term and there is no danger of disappearing. Due to the demand for high-flow transmission, digital cameras, mobile phones, MP3 and other electronic products will also be included in the Mini DiiVA connector socket in the future. Therefore, digital cameras, mobile phones, MP3 and other electronic products in the near future will have connectors of the above two specifications at the same time socket

However, setting the connector sockets of the above two interfaces at the same time will inevitably increase the size of electronic products, which is not suitable for the development of miniaturization of electronic products; In the same housing, that is, the housing includes two sets of terminals and two fixing seats at the same time. However, this combination method increases the thickness of the entire connector socket, which in turn increases the thickness of the electronic product on which the connector socket is installed, which is not conducive to The development of miniaturization of electronic products is not convenient to carry; the above two methods need to add a connector socket, which will inevitably increase the manufacturing cost

[0006] Of course, there are also people who try to set the terminals in the two connector sockets on the same socket, such as setting the two groups of terminals on the two connectors on both sides of the tongue plate on the same socket respectively, and on both sides of the tongue plate. Separately set up storage spaces for two types of mating plug connectors; however, for Micro USB and Mini DiiVA connector sockets that only have one row of terminals and the socket itself is small in size, adding a row of terminals must increase the tongue plate. Thickness, so it cannot be matched with a standard butt plug connector; if a row of terminals is added without increasing the thickness of the tongue plate, it will inevitably make the part of the tongue plate slotted to accommodate the terminals thinner and easy to break; and the tongue plate After the storage space is provided on both sides, the thickness of the connector socket will still be increased, and when in use, the upper or lower side of the Micro USB or Mini DiiVA plug connector cannot be limited, so it is easy to shake and fall off

In addition, the Mini DiiVA connector receptacle has more contacts than the Micro USB connector receptacle, and the tongue of the Mini DiiVA connector receptacle is wider than the tongue of the Micro USB connector receptacle; The conductive terminals on the receptacle are set to the tongue plate of the shorter Micro USB connector receptacle; and when the terminals on the Micro USB connector receptacle are set to the tongue plate of the Mini DiiVA connector receptacle, because the Mini DiiVA connector receptacle The tongue is too wide to connect with the standard Micro USB connector plug
