Gap reduces, and fits closely plane contact piece and contact surface, realizes shielding connection.
Preferably, the casing outer peripheral surface and contact surface joint form neck neck, and the elastic slice is by the end of seat shell body
After face compresses and the neck neck forms fulcrum, to provide elastic force.
Preferably, the connector further includes attachment cap, and the attachment cap is sheathed on the casing and seat shell body, energy
Enough by the seat shell body and casing butt-joint locking.
Preferably, the attachment cap is rotatably socketed on the casing, is led between the attachment cap and seat shell body
It crosses threaded connection or cooperates the connection of three spiral slot forms with three bayonet locks.
Preferably, the seat shell body also has chamfering in the endface, described when seat shell body and casing butt-joint locking
Chamfering can be pressed on elastic slice.
Preferably, the elastic slice is 130 ° ± 5 ° relative to the inclination angle of plane contact piece.
Preferably, the shielding finger is process through the stamping process.
Based on the above-mentioned technical proposal, the beneficial effects of the present invention are:
(1) present invention can reduce the axial shield installation length of connector using side pressure formula shielding finger, to reduce company
Connect the length of device.
(2) side pressure formula shielding finger mold is simpler, does not need the aftertreatment technologies such as electric resistance welding, can be greatly reduced and be produced into
This, provides better shield effectiveness.

Specific embodiment
The technical scheme of the present invention will be further described in the following with reference to the drawings and specific embodiments:
The invention discloses a kind of connector with side pressure formula shielding finger, it can be achieved that the installation of 2mm short space, bright
The aobvious axial dimension for reducing connector；Side pressure formula shielding finger structure more simply can be by the simple stamping die within a set of 10,000 yuan
It produces, cost is lower；After punch forming through surface treatment can direct-assembling use be not required to the other processing works of progress electric resistance welding etc.
Sequence.
Specifically, in one exemplary embodiment, as shown in Fig. 2, the present embodiment has the connection of side pressure formula shielding finger
Device includes seat shell body 1, casing 4, attachment cap 2 and side pressure formula shielding finger 3.
Wherein, attachment cap 2 is sheathed on casing 4 and seat shell body 1, can be by 4 butt-joint locking of seat shell body 1 and casing；Tool
Body, attachment cap 2 can be rotatably socketed on casing 4, and be connected through a screw thread between attachment cap 2 and seat shell body 1,
