Abstract

The utility model discloses an electrical connector assembly, which comprises a first connector and a second connector, both of which have a shielding shell shielded on the outside of the butt joint part of the insulating body, and an end and a shield shell are also assembled in the butt joint part of the first connector. The shell abuts against the metal shrapnel whose other end exceeds the mating surface; when the first connector is docked with the second connector, because the end of the metal shrapnel beyond the mating surface is closer to the second connector than the terminal, it is the first to connect with the second connector. The shielding shells are abutted so that the two shielding shells are conducted before the terminals, so that the accumulated static electricity is released in time before the telecommunications are conducted, and it plays a better role in preventing electromagnetic interference at the initial stage of the telecommunications conduction.

Description

Electric coupler component

The utility model is relevant a kind of electric coupler component, relates in particular to a kind of shielding casing of high density electrical connector assembly.

In electronics industry, circuit board is to be connected by electric connector with other electronic installation usually.Along with developing rapidly of Information technology, the function of electric connector day by day strengthens and improves.To the quickening that requires astonishing increase and transfer rate of data memory space, cause that connection interface changes a lot, high density electrical connector produces thereupon and is widely used in the electronics industry.These high density electrical connector numbers of terminals are numerous, can reach more than 200 pins, because the restriction of installing space, the electric connector size can not increase too many, therefore terminal pitch will become minimum, (Electro MagneticInterference, EMI) phenomenon is serious in the internal electromagnetic interference when causing the signal transmission.For the high density electrical connector of structure precision, the small electric magnetic disturbance that outside other electronic installation produces is also easily to the bigger influence of its telecommunication transmission generation.For preventing that the signal that the telecommunication transmission time is passed through from leaking to other electronic installation radiation; or the noise of other signal source enters; the electric connector particularly periphery, docking section of high density electrical connector generally all is coated with the metal shielding casing; avoid EMI with the telecommunication transmission of protection electric connector and disturb, the signal of further avoiding passing through disturbs outside other electronic installation generation.Simultaneously, electric connector also is provided with one or more ground strips that engage with shielding casing, to reach release electrostatic (Electro Static Discharge, effect ESD).

Yet; above-mentioned electric connector is when docking electric connector and connect; through conducting terminal contact conducting that the two appears in regular meeting formerly, the metal shielding casing engage after situation; so; at the telecommunication conducting initial stage; that is conducting terminal has contacted conducting and shielding casing when not engaging as yet; because of electric connector does not form electrically conducting with the shielding casing that docks electric connector; and the static that gathers on the electric connector can't in time be discharged, and cause the signal transmission quality of this moment relatively poor and extremely unstable because of the cause of electromagnetic interference.

Main purpose of the present utility model is to provide a kind of electric coupler component, wherein electric connector is when docking electric connector and connect, the shielding casing of the two engages formerly, the termination contact conducting after, the effect that can provide preferable anti-electromagnetic interference and static to discharge.

For achieving the above object, the utility model adopts following technical scheme: electric coupler component reaches second connector that matches with it by first connector and forms, wherein first connector includes members such as insulating body, shielding casing, plurality of conductive terminals and metal clips, above-mentioned insulating body has the docking section, the upper surface of docking section is an interface, is provided with the plurality of terminals accepting groove in this docking section at least; The plurality of conductive terminals group is located in the terminal containing slot of insulating body, and the one end stretches out to combine with circuit board from the body that insulate, and the other end extends to the interface place of insulating body; Shielding casing has the cover portions of maskable in the outside, docking section of insulating body, and the protection of covering to terminal is provided; The metal clips group is located in the docking section of insulating body, and one end and shielding casing connect, and the other end then exceeds interface; Second connector can connect with first connector, and it includes members such as insulating body, shading member and plurality of conductive terminals.

Compared with prior art, electric coupler component with above-mentioned feature can be reached following beneficial effect: when first connector and second connector connect, because the metal clips of first connector exceeds an end of interface compared to more close second connector of its conducting terminal, so it can take the lead in connecting with the shielding casing of second connector, and all terminals of first connector all do not contact with the terminal of second connector at this moment, make first connector and the shielding casing of second connector reach electrically conducting earlier than terminal, thereby telecommunication as yet not the moment of the conducting static of being about to earlier gather on the electric connector in time discharge, and promptly provide preferable anti-electromagnetic interference effect at the telecommunication conducting initial stage, make electric coupler component have the effect that preferable anti-electromagnetic interference and static discharge.
