Description
[technical field]
The relevant a kind of electric coupler component of the utility model refers in particular to a kind of electric coupler component with improved earthing mode.
[background technology]
Along with the miniaturization development trend of PC, more and more higher to the integrated degree requirement of mainboard, often need integrated numerous electronic component on the mainboard.Because the restriction of computer housing inner space, the size of mainboard is also restricted, causes the configuration and the installable electronic component of printed wire of mainboard limited.And along with consumption electronic products flourish that can carry out exchanges data with computer, computer connects and the supporting outer periphery equipment (as keyboard, mouse etc.) of computer except needs at present, also need connect consumption electronic products such as printer, digital camera, scanner, PDA(Personal Digital Assistant), this just requires numerous I/O Bu Kou is set on the cabinet panel, satisfies above-mentioned numerous external demand.
Yet, because the factor of the described mainboard of leading portion aspect, add the electric connector limited amount that to install on the ora terminalis of the contiguous cabinet panel of mainboard, under this situation, a kind of electric coupler component of computer housing inside has appearred being installed in, these electric coupler component one ends are installed on the computer case panel, and the other end is connected to electric connector corresponding on the mainboard, and this electric coupler component can reduce the configuration space of mainboard to a great extent.See also announce in the Chinese patent on January 27th, 1999 announce CN2305772Y number and announce October 27 in 1999 the purpose Chinese patent announce CN2346003Y number, these patents have disclosed a kind of foregoing electric coupler component.Also see also shown in Figure 1ly, this electric coupler component 90 has insulation lid 91 and is housed in some electric connectors 92 in the insulation lid 91 corresponding host cavities.Insulation lid 91 is to lock on a ground plate 94 by pair of screws 93, and the metal shielding casing 95 of each electric connector 92 leans with above-mentioned ground plate 94, and is connected by ground plate 94 assemblings and forms a grounding path on the cabinet panel and eliminate the noise that each electric connector 92 internal cause electromagnetic interference or cross-talk produce.
But, above-mentioned grounding path less reliable.Because electric connector 92 is to form to conflict by the insulation lid 91 and the locking of 94 of ground plates to be connected with ground plate 94, because the material of insulation lid 91 has certain pliability, so be subjected to the pin connector that docks with it repeatedly or excessively after the grafting when electric connector 92, one of them or several electric connectors 92 very easily contract (as shown in Figure 2) in the host cavity with respect to insulation lid 91, thereby cause the front end face and ground plate 94 poor electrical contact of the electric connector 92 that contracts in this, destroyed the integrality of grounding path, make in this electric connector 92 and can't lead away fully, and then influence the reliable transmission of signals in the electric connector 92 with the noise of its corresponding lead.
Though can consider to increase the electric connector front end face stretch out the limit size and with its by screw directly with the ground plate locking to strengthen the electrical steadiness that contacts therebetween, yet this measure will make manufacturing cost increase undoubtedly, and make troubles for the assembly and disassembly of this electric coupler component and ground plate.In view of this, necessary earthing mode to above-mentioned electric coupler component is improved the defective that exists in the prior art to overcome.
