接插件、插座等产品均需对其插拔力进行测量。插拔力的大小直接反映插件、插套（铜件）的质量，国家标准对其插拔力大小作了明确的规定，即插入力、拔出力必须在标准规定的量值范围内。插拔力测试仪必须解决的几个难题是：（）小负荷测量，应有过载等安全保护装置；（）能在插 Plug connectors, sockets and other products are required to measure its insertion force. Plug the size of the plug-in directly reflects the quality of plug-in, plug (copper pieces), the national standard of its insertion and removal force made a clear provision that the insertion force, pull-out force must be within the standard value range. Plug the force tester must solve several problems are: () small load measurement, there should be overload and other safety devices; () can be inserted
