Description

Card connector

【Technical field】

It the utility model is related to technical field of electric connectors, more particularly to a kind of card connector with trip mechanism.

【Background technology】

In general card connector on the market, there is an insulating body, the insulating body is provided with a host cavity, and multiple terminals are consolidated In insulating body, there is each terminal a contact site to be revealed in host cavity, and a shielding casing is covered in outside insulating body, is somebody's turn to do Host cavity is placed with for a Kato, because Kato needs to be often placed at host cavity and is exited from host cavity, therefore sets one to move back Mechanism for card operates Kato, and convenient use person, the trip mechanism is located in insulating body, and including a push rod and an ejection piece, User only needs to operate push rod, it is possible to ejection piece is pushed against by push rod, and ejection piece promotes Kato again, so that Kato Exited from host cavity.

The push rod of trip mechanism will be installed in insulating body, assemble process in manufacture to ensure that it movable can be pushed against, So design coordinates assembling for gap certainly, that is, coordinate and gap between fixed push rod and insulating body be present, this gap can be made Shaken into push rod in insulating body, so as to which the metalwork similar with shielding casing collides, produce abnormal voice, no It is easy to user to use.

Therefore, it is necessary to a kind of new card connector is provided to overcome drawbacks described above.

【Utility model content】

For background technology problem encountered, the purpose of this utility model is to provide a kind of by being set on push rod The shielded housing in convex portion compresses, and is not rocked so as to reach push rod, avoids sending the card connector of abnormal voice.

To achieve the above object, the utility model uses following technological means：

A kind of card connector, placed with for a Kato, it includes an insulating body, and multiple terminals are fixedly arranged on insulation originally Body, for a shielding casing outside the insulating body, shielding casing is provided with a resigning portion, between shielding casing and insulating body formed with There is a contact site to be revealed in the host cavity for one host cavity, each terminal, and host cavity is placed with for Kato, and a trip mechanism is set In insulating body, it has a push rod and an ejection piece, and push rod is provided with a convex portion, when Kato is positioned over host cavity, covers shell Body compresses the convex portion, and when Kato exits host cavity, convex portion is located at resigning portion.

Further, push rod and ejection piece are two-part construction, and push rod and ejection piece cooperate, and ejection piece has one to support Pushed section and a drive portion, Kato from host cavity exit outwardly when, push rod drives the drive portion so that pushing portion pushes Kato, card Hold in the palm towards outer displacement.

Further, convex portion protrudes out to be formed upwards from the top surface of push rod, when Kato exits host cavity, convex portion and masking shell Gap between body be present.

Further, shielding casing has a shell fragment, and resigning portion located at shell fragment and extends to be formed from shielding casing, from resigning Portion extends a pressure section, and when Kato is positioned over host cavity, pressure section compresses downwards convex portion.

Further, shielding casing has a roof and two side, and two side connects the roof respectively, and shell fragment is located at roof Close to the opening position of side wall.

Further, pressure section is bent to form downwards from resigning portion.

Further, host cavity has an opening, and the opening inserts the host cavity for Kato, and pressure section is with respect to resigning portion Closer to the opening.

Further, the both sides of shell fragment have a breach respectively.

Further, resigning portion is hollow-out parts, and when Kato exits host cavity, convex portion is located at hollow-out parts, when Kato is placed When host cavity, shielding casing compresses downwards convex portion.
