新式手扣射频测试头
本技术涉及一种测试头,尤其涉及一种新式手扣射频测试头。
技术介绍
目前移动通讯终端信号测试中,在装有板端连接器的信号模块载体上测试信号,通常都是用微小型射频端子线手扣于信号模块的板端连接器上(射频端子线的两片式插孔金属内导体簧片在人手推力的作用下咬合住板端连接器的圆形金属内芯连接导通;射频端子线的卡爪式外导体金属簧片在人手推力作用下咬合住板端连接器金属外壳的凹形圆槽面连接导通),在连接终端测试仪,实现信号传导测试。该射频端子线的主要材料金属簧片是铍青铜材料由模具冲压而成,金属簧片硬度和弹性不足,在实际信号测试中寿命较短(使用一段时间金属簧片失去弹力,无法与终端模块上的板端连接器紧密接触,使终端测试仪发出的信号无法接收,从而无法形成导通测试),目前市场标称寿命为80次。另外该射频端子线在信号测试中需要人手作业,但端子线体积较小,在实际使用中需要辅以工装夹具才能完成,致使在测试时效率较低无法满足客户需求。
