Description

Connector shell

[technical field]

The utility model is about a kind of connector shell, especially about the structure of the fixedly conduction cushion rubber of SFP (small form-factorpluggable) connector shell.

[background technology]

The notification number of on June 22nd, 2004 bulletin is that 6752663 United States Patent (USP) has disclosed a kind of SFP housing that is installed on female circuit board, and it comprises shielding casing with docking port and under shed, is installed on the preceding conduction cushion rubber of shielding casing docking port and is installed on the shell fragment of shielding casing under shed and conduction cushion rubber down.Shielding casing is provided with the lower limb near under shed.Shell fragment contacts to set up conductive path between this connector and female circuit board with the interior connector of shielding casing of packing into.

But the defective of this design is: when connector repeatedly plugged in shielding casing, following conductive gasket was easily loosening and to front slide, thereby caused that easily the terminal with connector misleads.

[utility model content]

Technical problem to be solved in the utility model is to provide a kind of can effectively fix the connector shell of conduction cushion rubber down.

For reaching above-mentioned technical problem to be solved, the utility model provides a kind of connector shell, it comprises shielding casing and conducts electricity cushion rubber down, described shielding casing comprises roof, diapire and pair of sidewalls, be provided with opening after the described diapire, the described cushion rubber of conduction down is immobilizated on the described opening and has the bearing surface that faces the roof configuration, wherein, the edge is provided with the location division of extending towards described opening after the described diapire, and described location division compresses down the bearing surface of conduction cushion rubber to locate down the conduction cushion rubber.

Compared with prior art, the utility model module connector has the following advantages: thus the bearing surface order that the location division of shielding casing compresses down the conduction cushion rubber down the conduction cushion rubber realize reliable location.Thereby the cushion rubber that conducts electricity is down avoided itself and the terminal that inserts the SFP connector in the connector shell to mislead by secure fixation in both allocations.

[embodiment]

See also Fig. 1 to Fig. 3, the utility model discloses a kind of connector shell 100, and it can make SFP connector (not shown) pack in it to dock with banjo.This connector shell 100 and its interior SFP connector of packing into can be installed on female circuit board (not shown).Described connector shell 100 comprises: shielding casing 1, be assembled in flexible member 3 on the shielding casing 1, be used to improve the preceding conduction cushion rubber 2 of anti-electromagnetic interference effect and conduction cushion rubber 4 down.

Shielding casing 1 is roughly rectangular, comprises roof 11, diapire 13, rear wall 15 and pair of sidewalls 12.The front end of shielding casing 1 is provided with by roof 11, sidewall 12 and diapire 13 and encloses the docking port 10 that forms.Roof 11 is provided with window 111.Form opening 131 between the rear end of diapire 13 and the rear wall 15.The back edge of diapire 13 is provided with towards opening 131 near opening 131 places and omits the upwards location division 132 of bending.Sidewall 12, diapire 13 and rear wall 15 are provided with some installation feet 14 of downward extension.The installation foot 14 of shielding casing 1 can be fixed in female circuit board by the crimping mode.

Flexible member 3 comprises holding piece 31 and shell fragment 32.

The cushion rubber 4 that conducts electricity down comprises first arm 41 and three second arms 42 of head and the tail connection each other.First arm 41 has bearing surface 411.Be respectively equipped with some slits 421 and upwardly extending zigzag interference part 422 on each second arm 42.

During assembling connector shell 100, flexible member 3 is sheathed on the docking port 10 of shielding casing 1.Make holding piece 31 be disposed at the outside of roof 11, sidewall 12 and diapire 13, and make shell fragment 32 be disposed at the inboard of roof 11, sidewall 12 and diapire 13.Preceding conduction cushion rubber 2 is sheathed on flexible member 3 outsides.The cushion rubber 4 that will conduct electricity down is sheathed on the opening 131, makes first arm 41 face roof 11 near location division 132 and bearing surface 411, and makes a pair of second arm 42 in three second arms 42 cooperate with pair of sidewalls 12, and another second arm 42 cooperates with rear wall 15.Make the bearing surface 411 of location division 132 against first arm 41 of preceding conduction cushion rubber 2.The slit 421 that makes installation foot 14 pass through down conduction cushion rubber 4 extends downwards.At this moment, interference part 422 is positioned at sidewall 12 and rear wall 15 and is used for and packs its SFP connector interference into.

When the SFP connector repeatedly plugs in the connector shell that is not provided with location division 132, thereby the portion's 132 fixing following conduction cushion rubbers 4 that are not positioned make the 41 inside perks of first arm to front slide easily.When repeatedly plugging in the connector shell 100 of SFP connector in the utility model, first arm 41 conducts electricity cushion rubber 4 down to front slide owing to be subjected to compressing and not inwardly perk of location division 132 thereby stop.Thereby the cushion rubber 4 that conducts electricity is down avoided itself and the terminal that inserts the SFP connector in the connector shell to mislead by secure fixation in both allocations.In addition, location division 132 is one-body molded with the diapire 13 of shielding casing 1, thereby makes that processing procedure is stable and save assembly process.
