Description
Technical field
The utility model relates to a kind of connector with leverage and connector assembly.
Background technology
In the connector technique field, the connector that sometimes needs to have large quantity stitch is plugged in together mutually, for example, has the connector of 40 stitch, 89 stitch or more stitch.When the connector pin pin number is too much, can cause contact engaging and separating force excessive, therefore, in the prior art, generally adopt leverage to reduce contact engaging and separating force.
Fig. 1 has shown a kind of existing lever-type connector assembly, and it mainly comprises male connector 100 ', parent form connector 200 ' and with the force-increasing mechanism of leverage 300 '.As shown in Figure 1, leverage 300 ' is rotatably connected on the housing of male connector 100 '.For example, can be provided with installing hole 301 ' on the end of leverage 300 ', be connected rotationally with pivot 101 ' on the housing of male connector 100 '.
Force-increasing mechanism also comprises a transformational structure, and this transformational structure is connected with leverage 300 ' and leverage 300 ' is rotated the power that produces and converts to joining the contact engaging and separating force of male connector 100 ' and parent form connector 200 '.For example, transformational structure is included in the gear part 303 ' (gear that has only shown a side among the figure) of the end formation of leverage 300 ' link.Transformational structure also comprises the slurcam 110 ' that the housing with male connector 100 ' can be dynamically connected.For example, slurcam 110 ' can flatly horizontally slip in the slide rail 120 ' on the housing of male connector 100 '.Be provided with tooth bar 111 ' (tooth bar that has only shown a side among the figure) on this slurcam 110 ', can mesh with the gear part 303 ' of leverage 300 '.Therefore, when rotating lever mechanism 300 ', slurcam 110 ' can slide with respect to the housing left and right horizontal of male connector 100 ', thereby converts rotatablely moving of leverage 300 ' to horizontal movement.
Please continue referring to Fig. 1, can be provided with one or more skewed slots 113 ' on slurcam 110 ', this skewed slot 113 ' cooperates with one or more protruding 203 ' of parent form connector 200 ' upper setting.Therefore, when slurcam 110 ' slides with respect to male connector 100 ' housing left and right horizontal, parent form connector 200 ' can move relative to male connector 100 ' along the skewed slot 113 ' of slurcam 110 ', thereby convert the horizontal movement of slurcam 110 ' the vertical movement of above-below direction to, namely plug the plug campaign of male connector 100 '.
Like this, in connector assembly shown in Figure 1, when along instantaneous pin direction rotating lever mechanism 300 ', slurcam 110 ' relatively male connector 100 ' moves to left.By cooperating of the projection 203 ' on the skewed slot 113 ' on the slurcam 110 and the parent form connector 200 ', just can force the mutually closely motion of male connector 100 ' and parent form connector 200 ', thereby male connector 100 ' is inserted in the parent form connector 200 '.On the contrary, when rotating lever mechanism in the counterclockwise direction 300 ', slurcam 110 ' relatively male connector 100 ' moves to right.By cooperating of the projection 203 ' on the skewed slot 113 ' on the slurcam 110 ' and the parent form connector 200 ', just can force the mutually remotely motion of male connector 100 ' and parent form connector 200 ', thereby male connector 100 ' is extracted from parent form connector 200 '.
But, in prior art shown in Figure 1 because the limited space of connector, even in limited space to the leverage rational deployment, the arm of force of leverage also can not be very long, therefore, still needs very large operating physical force when plug-in connector.
