Description

Bayonet connector

Technical field

The utility model relates to a kind of electric connector, and the telecommunication that particularly relates to a kind of plug-in card of arranging in pairs or groups connects use, and has the stable bayonet connector that reaches the excellent operation feel of butt joint.

Background technology

Connecting or the setting of functional devices of the many signals of existing computer, all operate to connect and finish by plug-in card, it use to be gone up by a circuit board is that the plug-in card formed of matrix is (as sound card, internal memory plug-in card or the like), the spigot of this plug-in card is provided with several telecommunication guiding access, and it is inserted in bayonet connector (CardEdge/ such as SIMM, DIMM etc.) in the central slot, the fastener button that relends these bayonet connector two ends after the insertion is tied in the short slot of this plug-in card two corresponding end, this plug-in card firmly is plugged on this bayonet connector, and the telecommunication guiding access of this plug-in card is connected mutually with the conducting terminal of bayonet connector, to finish the transmission channel of signal; Though existing bayonet connector can plug and locate the plug-in card that binding plugs, but still have disappearance in its operation, for example, plug-in card is in inserting the central slot of bayonet connector the time, the fastener at these bayonet connector two ends can inwardly rotate closing along with compressing of plug-in card, and in the short slot that buckles into these plug-in card two ends at last, but this fastener is along with compressing gradually of plug-in card carried out in the buckle process of rotation closing, the operator only can detect the short slot whether this fastener is snapped in this plug-in card really with visual, perhaps further reverse this plug-in card of drawing detects this plug-in card and whether is stabilized the button knot really, but may reduce the connectivity of this bayonet connector thus, it is bad perhaps to cause local signal to connect, and the phenomenon that is difficult to certain perception control in this kind operation, be because plug-in card is a kind of dynamic operation, and bayonet connector itself there is no any mechanism with the operation feedback and is provided with, make the operator only can firmly plug-in card be inserted to end perception as far as possible, obviously, this kind mode of operation and nonideal mechanism design are so there is necessity of improvement.Therefore, how improving the operational disappearance of this type of bayonet connector, and promote it and stablize firm bed knife, is that industry should further be made great efforts the important topic that solves, overcome.

Summary of the invention
