Description

一种检测装置的测试探针 技术领域
本发明涉及一种测试探针，特别是指一种包括针套以及探针，其中，该针套包括第一连接端、第二连接端以及连接导线，该连接导线柔性连接在该第一连接端与该第二连接端之间的测试探针。
背景技术
目前各种数码数字产品已经很普遍的被适用在了人们的生产、生活中了，就一般的数码数字产品而言，其内部一般都设置有多种电子功能模块，在具体工作的时候，若干电子功能模块通电工作以使相关产品能够实现特定的功能，比如，移动手机中一般包括有信号接收模块、信号发射模块、控制模块等等，而在具体实践中，数码数字产品中各个模块的工作状态、产品质量往往能够决定整体产品的产品品质，在生产制造的过程中对相关功能模块进行测试就成为了保障产品质量的有效手段。
就目前市面上出现的测试功能模块的治具而言其一般包括测试板以及测试电路板，在工作的时候，需要将被检测的模块放置在测试板中，测试电路板上焊接有固定测试探针，当测试探针接触测试板上对应位置后被检测的模块的信号通过测试电路板传送到测试仪器中以完成测试，但是这种测试治具在具体使用的时候还存在着诸多的缺点现在分述如下：首先，其同一根测试探针无法实 现转接多种测试信号，其次，其针套较长，针套先焊接在PCB板上时，焊锡渗入到针套里面，堵塞了针套，导致探针插入的时候无法到底，导致探针高低不平，在针套焊锡固定后，无法灵活转接到PCB板上其他位置的针点，测试探针的密集导致了PCB板位置空间的不足以及电子走线空间的不足，而此是为现有技术的主要缺点。
发明内容
本发明提供一种检测装置的测试探针，其探针部分能够自由长距离大跨度移动，从而支持多个点为的测试工作，方便测试人员检测，而此为本发明的主要目的。
本发明所采取的技术方案是：一种检测装置的测试探针，其包括针套以及探针，其中，该针套包括第一连接端、第二连接端以及连接导线，该连接导线柔性连接在该第一连接端与该第二连接端之间，该探针插接在该第二连接端上，在具体实施的时候，该第一连接端焊接在测试PCB板上，并在该位置形成第一信号连接区域，在该测试PCB板上还设置有其他信号连接区域，由于该连接导线是柔性连接在该第一连接端与该第二连接端之间的，所以当该探针插接在该第二连接端上的时候，该探针能够长距离大跨度的从其他信号连接区域处插入该测试PCB板，从而完成对该测试PCB板下方测试板上功能模块的测试工作。
该第一连接端包括第一柱子针以及套筒，该第一柱子针插设在该套筒下端部，该连接导线一端插设在该套筒的上端部，该第二连接端连接在该连接导线的另外一端，该第二连接端为一柱子针，该探针包括针套以及针头，其中，该 针头插设在该针套的下端部，该第二连接端插设在该针套的上端部，在具体实施的时候，该第一柱子针与该套筒的连接位置、该连接导线与该套筒的连接位置、该第二连接端与该连接导线的连接位置、该第二连接端与该针套的连接位置分别设置有卡位，从而使各个部分紧密连接。
本发明的有益效果为：本发明的的针套分两部分，其中一部分带软线连接，可以自由与另外一部分针套连接，PCB板上的焊锡位置点位置可以自由选择位置，使同一根测试探针能够实现转接多种测试信号，本发明能够完全杜绝焊锡渗漏的问题，因为本发明中，针套并无内孔从而避免渗锡情况的发生，本发明的针套与PCB板焊锡处没有渗透孔的结构，另外本发明能够给电子线路布局走线提供充足的空间，因为本发明中，PCB板焊锡位置可以自由选择位置，灵活转接到PCB板上其他位置针点。
