In the present embodiment, elastic grounding arm 8 is the overhanging grounding arm to overhang on shielding sheet matrix 1, to save material, together When can guarantee the elasticity of elastic grounding arm 8 so that elastic grounding arm 8 contacts well with ground strip 10.In other embodiments, Elastic grounding arm and shielding sheet matrix are wide or be slightly less than the width of shielding sheet matrix, and bullet is less likely to occur elastic grounding arm at this time Property deformation.

Such as Fig. 1 and Fig. 2, in the present embodiment, the front-end and back-end of shielding sheet matrix 1 are extended with overhanging linking arm 7, bullet opposite to each other Property grounding arm 8 and overhanging linking arm 7 connect far from one end of shielding sheet matrix 1, and L-shaped arrangement, on corresponding insulator 12 Equipped with the limiting slot for installing elastic grounding arm 8 and overhanging linking arm 7, corresponding limiting slot is L-type, in order to elasticity ground connection The assembly of arm 8.It in other embodiments, can not include overhanging linking arm, elastic grounding arm is directly inside by shielding sheet matrix Bending, only needs to open up "-" type limiting slot on insulator at this time.

As shown in Figure 5 and Figure 6, contact contact portion 3 be projection shielding 1 lower inside of sheet matrix contact portion contact, Contact portion contact be disposed with along the extending direction of shielding sheet matrix 1 it is multiple, for being contacted with the ground connection on corresponding intermateable connector Part conductive contact to guarantee that contact and the contact for shielding piece are good, and then guarantees shield effectiveness.In other embodiments, may be used The quantity of contact portion contact is set as needed.In other embodiments, in order to guarantee contact contact portion and shielding The contact of piece is good, and contact contact can be columnar projections.In other embodiments, ground strip contact portion can be shielding piece The inner wall of matrix 1.Contact contact portion 3 in the present embodiment is stamped and formed out inwardly by the outside of shielding sheet matrix 1.At it In his embodiment, the contact contact portion can be welded on shielding sheet matrix or be integrally formed the contact contact portion.

In the present embodiment, shielding slice mounting structure 2 is shielding piece mounting hole, and shielding piece mounting hole is along shielding sheet matrix 1 Extending direction is disposed with multiple, and is correspondingly provided with a contact contact portion below each shielding piece mounting hole.Shield piece peace Dress hole is up-small and down-big structure, and the side wall of insulator 12 is equipped with and the shielding one-to-one fixed block 9 of piece mounting hole, fixed block The mounting groove for installing shielding piece is surrounded between 9 and the side wall of insulator 12, i.e. fixed block 9 is hierarchic structure, in shielding piece It is mobile still further below to be installed on shielding piece after being moved to the top of mounting groove by the big mouth of shielding piece mounting hole in left-right direction In mounting groove, it is installed on insulator 12 convenient for shielding piece, and can be after shielding sheet matrix 1 is installed in place, limitation shielding chip base Body 1 moves down.In other embodiments, piece can will be shielded by fastener to be fixedly mounted on insulator.The present embodiment In, fixed block is prism structure, and in other embodiments, fixed block is cylindrical structure.

In the present embodiment, shields and extend along direction on sheet matrix 1 equipped with multiple position limiting structures, in shielding piece installation Shielding piece limit is provided with a limit on insulator 12, and every two shielding slice mounting structures 2 after on to insulator 12 Bit architecture, to guarantee to move up after shielding piece is installed on insulator.In the present embodiment, position limiting structure includes limit hole 6 and the positive stop spring plate 5 that is arranged in limit hole 6,5 lower end of positive stop spring plate is fixed on the lower hole wall of limit hole 6, and positive stop spring plate 5 extend inwardly from bottom to top.The side wall of insulator 12 be equipped with limiting slot 13, with positive stop spring plate 5 with shielding sheet matrix 1 under Limiting slot 13 is caught in after shifting under natural resiliency effect, and then realizes that the limit of positive stop spring plate 5 and limiting slot 13 cooperates, with limitation Shielding sheet matrix 1 moves up, and by cooperating with shielding piece mounting hole, shielding sheet matrix 1 is avoided to be installed on insulator 12 After teetertotter.In other embodiments, it can according to need the quantity of setting position limiting structure, or be not provided with position limiting structure. In other embodiments, it will not be moved up to guarantee to shield after piece is installed on insulator, it can be directly by positive stop spring plate It is welded on the inner sidewall of shielding sheet matrix.

As shown in figure 4, the position that the upper end of shielding sheet matrix 1 corresponds to grounding component 11 is equipped with support protrusion 14, support Protrusion 14 cooperates with insulator 12 with supported grounding contact 11, and then guarantees the stability of grounding component 11.In other realities It applies in example, if grounding component 11 is sufficiently stable in the case where dielectric support, does not need setting support protrusion.

As shown in fig. 6, the outside of the correspondence insulator 12 of shielding sheet matrix 1 has the bending segment extended along the longitudinal direction 15, which extends outwardly from top to bottom and is in the lower section of positive stop spring plate, to guarantee shielding sheet matrix 1 and insulator 12 It is close to assembly, avoids shielding 1 double swerve of sheet matrix, to guarantees that shielding sheet matrix 1 and the contact of grounding component 11 are good. In other embodiments, after shielding sheet matrix is put into the mounting groove surrounded between fixed block and the side wall of insulator, if energy It is enough to guarantee that shielding sheet matrix shake along the longitudinal direction, bending segment can be not provided with.

In the present embodiment, the ground strip contact portion 4 of the elastic grounding arm 8 of two shielding piece front and back ends is respectively and before insulator 12 10 conductive contact of ground strip of rear end, to form the full-closed structure arranged around conductive contact piece 16 and grounding component 11, It ensure that the shield effectiveness of connector, and also act as the exterior protection effect to insulator.

In the present embodiment, which be can be applied on board to board connector, and ground strip 10 (is not shown with printed board pad Show) connection, to realize the earth shield of connector.

The specific embodiment of shielding piece of the invention, the specific embodiment of shielding piece and above-mentioned connector in the present embodiment Described in shielding piece structure and function it is identical, details are not described herein.
