零插拔力插座

ZIF socket for DIP packages
A large ZIF socket (Socket A)
Programming device for a PIC microcontroller, with a dual in-line ZIF socket
A pair of ZIF connectors, with the flexible flat cable that connects to them.

零插拔力插座英语:ZIF, Zero insertion force),又称ZIF插座,是一种只需很少力就能插拔的集成电路插座或电子连接器。这种插座通常附有一支杠杆或者滑杆让用户只要将之推开或拉开,插座内的弹簧式接点就会被分开,其时只要非常少的力就能把集成电路插下去(一般而言芯片自身的重量即可给予足够的力)。然后当杠杆或者滑杆回到原位后,接点便会被重新闭合并抓紧芯片的针脚。ZIF插座由于这种杠杆设计,因而会比普通其他插座贵很多,也需要较大的面积放置杠杆,所以只有需要经常插拔时才会用到。

这种插座不需像传统插座一样需要工具辅助,也降低因插拔导致针脚弯曲甚至断裂的问题。

Zero insertion force (ZIF) is a type of IC socket or electrical connector that requires very little force for insertion. With a ZIF socket, before the IC is inserted, a lever or slider on the side of the socket is moved, pushing all the sprung contacts apart so that the IC can be inserted with very little force - generally the weight of the IC itself is sufficient and no external downward force is required. The lever is then moved back, allowing the contacts to close and grip the pins of the IC. ZIF sockets are much more expensive than standard IC sockets and also tend to take up a larger board area due to the space taken up by the lever mechanism. Therefore they are only used when there is a good reason to do so.
