Description

Pin connector

The utility model is a kind of pin connector, refers in particular to a kind of pin connector that is connected cable terminations and wherein is provided with earth terminal.

Usually when the electric signal of high-speed high frequency transmits between two kinds of electronic installations by cable, very easily be subjected to the interference of external electromagnetic waves and cause the electric signal transmission unstable, therefore general cable products inside is equipped with the layer of metal shielding layer, and this metal shielding layer mostly is wire braid.In addition, when the transmission of the electric signal of high-speed high frequency, cause easily between each lead that in cable electrostatic charge assembles, make to have a large amount of electrostatic charges on the cable and have high voltage, and damage electronic installation easily or the operator is come to harm.For solving this electrostatic problem, common a kind of practice is that the wire sheathing in the cable is connected on the metal shading member of cable terminations pin connector, when pin connector docks with the input/output end port of electronic installation, borrow the metal decking at this metal shading member and electronic installation input/output end port place to connect, thereby constitute a ground connection conductive path by wire sheathing, shading member and metal decking, the electrostatic charge of being assembled on the cable is derived.And the another kind of common practice is that the wire sheathing of cable is connected with several conducting terminals in the cable terminations pin connector, the terminal of the butt connector on borrowing these conducting terminals and being installed in circuit board contacts, and constitute a ground connection conductive path, thereby the electrostatic charge on the cable is derived by wire sheathing, cable terminations connector conducting terminal, butt connector terminal and circuit board ground path.Yet, aforementioned first kind of method that derives static is to contact with metal decking and realize by shading member, and contacting between this metal shading member and metal decking has tangible uncertainty, easily because of untrue situation appears contacting in user's human factor, the effect that consequently derives static is bad.And second kind of situation often is limited by the connected mode between wire sheathing and conducting terminal technically, because the configuration of conducting terminal is quite tiny mostly, be difficult for welding or other connects operation, thereby be difficult to shorten and produce man-hour, this production efficiency of products of unfavorable raising.

The purpose of this utility model is to provide a kind of pin connector, its earthy conducting terminal is connected firmly with metal shielding layer in the cable, and connected mode is simple, can effectively simplify ground connection conducting terminal structure, and also enhance productivity shortening product assembling man-hour.

The purpose of this utility model is achieved through the following technical solutions: this pin connector is provided with enclosing cover, shading member, insulating body, several modular terminal member and earthing components, it is characterized in that: described earthing component comprises that one is the flat substrate of lengthwise and is combined in gripping arm on the substrate, wherein the lateral margin place, end both sides of substrate longitudinally extend symmetrically respectively be provided with two each bend and be approximately perpendicular to first of substrate in the opposite direction and fix sheets and second and fix sheets, and fix between sheet this first and second and to be formed with a suitable fixing space; Be closed square frame body and grip arm, each has the rib of convex towards the inner punching out of framework on its two relative side, borrows these ribs to fix that first and second fixes the place, fixing space between sheet and this gripping arm firmly is combined on the substrate at substrate.Like this, can grip between arm and substrate biside plate face at this and respectively be formed with grasping part, and after the cable lead inserts these grasping parts, these can be gripped further compression and cable is gripped of arm, and contact with the metal shielding layer of cable lead and reach the effect of ground connection by gripping arm.

According to above-mentioned feature, wherein on this earthing component also group be provided with an additional terminals component, it comprises and is used to the collets taking in conducting terminal and fix with earthing component, and these collets are provided with four conducting terminals that run through the collets rear and front end.

Compared with prior art, advantage of the present utility model is: its earthy conducting terminal is connected firmly with metal shielding layer in the cable, and connected mode is simple, can effectively simplify ground connection conducting terminal structure, and also enhance productivity shortening product assembling man-hour.
