Description

The shield shell leg structure

Technical field

The utility model relates to a kind of shield shell leg structure, relates in particular to a kind of sheathed metal gasket and fits tightly the leg structure in the acquiescence welding position.

Background technology

Computer science and technology is fast-developing now, desktop computer or notebook computer have been prevalent in each corner in society, the development trend of computer makes ancillary equipment miscellaneous (as mouse, keyboard, modulator-demodulator, the peripheral product such as digiboard) also with big Chang Qi road, wherein the computer-internal main frame just needs to be equiped with the joint that numerous connectors connects various ancillary equipment, the transmission electronic signal of usining is used as controlling, and there is acquired information and when transmission has convenient characteristic rapidly because of the network technology, become in current personal lifestyle or one of the indispensable resource of company, main frame also needs to set up the network connector that can dock for Network plug, this kind of network is all to take the RJ45 pattern as main by the connector major part, in order to the communication bridge as main frame and external network, and be connected to LAN (LAN) by the RJ45 connector or connect integrated service digital network (ISDN) device to network terminal device (NT-1) device through main frame.

Moreover, along with significantly dwindling of computer mainframe internal space, various electronic components on the mainboard that main frame is used, volume also must reduce thereupon, to avoid taking locus too many on circuit board, so just necessary electronic components can fully be set, but, network connector in order to the transmission network signal on mainboard easily is subject to the external noise interference and affects the degradation that network signal transmits, and the reason that is subject to noise jamming is broadly divided into two major parts, one is from the Electromagnetic Interference around network connector, its two internal interference that is network connector, thereby make the easy generation of network connector can disturb the high-frequency electric wave of other electric equipment, and the signal of connector own is also easily affected by the noise produced in external transmission lines, so, just having research and development to design for the network connector outer rim has covered metal screen case and has solved above-mentioned disappearance for being provided with filtration module in connector, the external network signal that so just network connector can be received carries out the filtering action, the unnecessary noise with filtering, and the actual useful signal of reservation, and then network signal can be passed to external control circuit interface (as: PCI-Express interface) the isotactic data transmission interface of formatting, with this, network signal is converted to the string type data transfer signal, just can be used for being processed in data handling system.

But, cover the shield shell in the network connector outside, must together be positioned at welding position on circuit board along with the plural terminals of network connector, to produce earthing effect, and then the noise of network connector outside or electromagnetic wave etc. can be given to filtering, when yet network connector is fixed on circuit board welding position, the also contraposition respectively of each ground connection pin in the shield shell outside, be resisted against each welded contact on circuit board, carry out the weld job of surface mount pattern (SMT), be usually located at each ground connection pin of shield shell lateral surface, all by after the directly outside punching press in shield shell side, the reprocessing bending forming, the irregular phenomenon of bending side or Yin Teding easily occur electroplate material, be difficult for being welded on the welded contact of welding position of circuit board, perk or the situation such as laminating not can occur, after carrying out welding processing, will cause between each pin of shield shell and welded contact and produce space, weld untrue empty weldering situation etc., make the earthing effect variation of shield shell, and each metallic contact of the plural terminals of remote-effects electric connector and circuit board, produce empty weldering or weld untrue phenomenon, cause the signal transmission of network connector unstable.

So, how to solve current network connector outside and cover problem and the puzzlement of ground connection pin moulding out-of-flatness, the perk of when welding or the empty weldering of shield shell, and solve disappearance and the troubles such as filter function, the network connector signal transmission affect shield shell be unstable, be the direction place of institute of the relevant manufacturer wish research improvement of being engaged in the industry.

Summary of the invention

Defect in view of above-mentioned shield shell, the purpose of this utility model is: design a kind of each pin for shield shell and fit tightly in the acquiescence welding position, form and stablize solder bond, produce good filter effect, and transmit stable shield shell leg structure for network signal.

Technical solution of the present utility model is: a kind of shield shell leg structure, described shield shell is coated on the insulating base frame outside of electric connector, two lateral surfaces at this shield shell convex with respectively one or more pin, each pin of described shield shell two lateral surfaces is respectively equipped with the open-work of hollow out, and described each pin is arranged with respectively the metal gasket that is placed in the acquiescence welding position for being tight against.

Further, described metal gasket is provided with smooth base portion, and described base portion both sides are respectively equipped with the fin oppositely turned down towards relative inner, the inner socket space that forms hollow form of base portion and two fins, and the pin that has open-work for the shield shell both sides penetrates.

Further, described base portion convexes with for the blocking cramp of buckle on the open-work of each pin.

Further, described electric connector is RJ45 type network electrical connector.。

The designed shield shell leg structure of application the utility model, the socket space can see through each pin of shield shell two lateral surfaces, utilize respectively two fins of metal gasket to be tight against on the welded contact that is placed in the acquiescence welding position simultaneously, play the technique effect that fits tightly, is difficult for producing space and stable solder bond.
