一种PCB测试专用机用弹簧连线
摘要：
本发明公开了一种PCB测试专用机用弹簧连线，包括由弹簧中段和两端设有的弹簧密卷一体绕成的测试探针托体和与弹簧连接的电子导线，其特征在于：所述弹簧的直径Φ为0.45＞Φ≥0.13，弹力为5g～20g。本发明的弹簧尺寸可使得测试点间距在0.22mm～0.20mm，并且测试点可相对集中，密度高，而且成本低廉，可针对目前市面上80％密度板(智能手机、手持电脑等所需测试夹具)。
摘要（英）：

The invention discloses a spring connection wire for a PCB special testing machine. The spring connection wire for the PCB special testing machine comprises a testing probe supporting body winded integrally by spring mill rolls arranged in the middle and at the two ends of the spring and electronic wires connected with the spring. The spring connection wire for the PCB special testing machine is characterized in that the diameter Phi of the spring is within the range from 0.13 to 0.45, and elastic force of the spring is 5g to 20g. According to the spring connection wire for the PCB special testing machine, the spring size enables the separation distance between every two testing points to be within the range from 0.20mm to 0.22mm, the testing points are relatively concentrated, density is high, cost is low, and the spring connection wire for the PCB special testing machine can be applied to 80 % of density boards (testing fixtures needed by smart cell phones, laptop computers and the like) in the current market.
