And a light guide seat is arranged between two vertically adjacent transverse spacers, one end of the light guide column is inserted into the clamping groove of the base through the positioning column, and the other end of the light guide column is inserted into the light guide seat.

Furthermore, the main body shell and the top cover of the shielding shell are provided with elastic sheets which are integrally formed.

Furthermore, the surface of the base is also provided with a plurality of limiting convex columns, and the front walls of the light guide columns are abutted against the limiting convex columns.

Furthermore, the surfaces of the two sides of the base are also provided with installation slots, and the two sides of the main shell of the shielding shell are provided with folded edges which are bent inwards and are inserted into the installation slots.

The utility model discloses an useful part lies in:

1. the design of leaded light post contains radian portion and extension, and radian portion inlay card is between two adjacent spacing projections, and the radian structure can ensure that leaded light post itself has certain movable allowance, can realize leaded light post and LED lamp pearl elastic contact.

2. Set up the fashioned shell fragment of integrative blanking on the main part shell of shield shell and the top cap, this fashioned shell fragment of integrative blanking can solve traditional SFP optical interface cage shell fragment and need produce the equipment alone, consumes man-hour and problem with cost.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

The utility model provides a take SFP optical interface cage of leaded light post, includes shielding shell, leaded light post 2 and base 1, and the base cartridge is equipped with a plurality of draw-in grooves 103 in the shielding shell on the base, is equipped with a plurality of reference columns 201 on the leaded light post, and the reference column is pegged graft in the draw-in groove. The clamping groove quantity can be a pair or a plurality of pairs, the specific quantity is set according to the specific use requirements of the product, a plurality of positioning columns are respectively inserted into the clamping grooves, and the clamping grooves play a role in fixing the positioning columns. The shielding shell comprises a main body shell 302, a transverse spacer 305, a vertical spacer 304, a rear cover 301 and a top cover, wherein the vertical spacer is vertically arranged in the main body shell, the transverse spacer is transversely arranged between the main body shell and the vertical spacer and between the vertical spacer and the vertical spacer, the top cover covers above the main body shell, the rear cover covers at the rear end of the main body shell, and all parts can be assembled into a complete shielding shell in a buckling mode.

The light guide post includes a curved portion 2002 that is clamped to the surface of the base and an extension 2001 that extends into the body housing. The tip of radian portion is contradicted on the LED lamp pearl of PCB board, and the extension level extends to the shielding shell other end and plug in leads light seat 4, and LED lamp pearl passes through light guide post light conduction to extension tip. Because the radian structure of radian portion and the LED lamp pearl of welded on the PCB board are highly different for LED lamp pearl is elastic contact with the leaded light post, has avoided LED lamp pearl and leaded light post hard contact, causes the damage to LED lamp pearl. The light guide seat is arranged between the two transverse spacers.

Be equipped with integrated into one piece's shell fragment 3001 on the main part shell of shielding shell and the top cap, this shell fragment is directly punched out from shielding shell main part and top cap, through this integrated into one piece's shell fragment structure, can save the process that needs punch alone the equipment shell fragment part in the traditional architecture, has promoted production efficiency, has also practiced thrift product cost simultaneously.

The surface of the base is also provided with a plurality of limiting convex columns 101, and the front walls of the light guide columns are abutted against the limiting convex columns. The leaded light post antetheca supports and leans on spacing projection, and when LED lamp pearl and leaded light post extrusion, spacing projection plays limiting displacement to the leaded light post antetheca for arc portion is elastic contact with LED lamp pearl.

The surface of both sides of the base is also provided with an installation slot 102, and both sides of the main body shell of the shielding shell are provided with folded edges 3002 which are bent inwards and inserted into the installation slot.
