Description
技术领域
本发明涉及电路设计技术领域,具体是种基于铜基体插孔连接汇流插座。该插座可用于实现多导线的快速短接,以替代采用焊接实现多导线短接的方法,适用于导线数量多、空间狭小的产品,同时可避免产品中“限制使用一点多线焊接”带来的虚焊缺陷的发生,具有接线密度高、回流能力强的特点。
背景技术
随着产品小型化、多功能化的发展需要,电子电气产品空间越来越小,而对于有大电流控制的产品,限于连接器功能分配和载流能力要求,输入端必须将多个导线汇集后转出或转接,为配合功能实现,此类转接往往不止一组。
目前在产品中,大多使用压接端子反复转接缩减导线数量,但对于多达20根以上的汇流端子而言,仅压接端子的空间就已经不能满足产品装配要求。因此,为实现产品功能,大多数厂家采用多根导线绞合、搪锡、焊接的方法进行回流短接,此方法对操作人员技术、工具、过程控制要求非常高,必须保证搪锡到位、熔融充分、焊接中无应力扰动等,否则极易带来虚焊,同时绞合中助焊剂残留无法清洗干净,长期使用中存在接点被腐蚀的隐患。
发明内容
针对现有技术的不足,本发明提供一种基于铜基体插孔连接汇流插座,该插座可以解决“一点多线的限用工艺”和助焊剂残留带来的隐患,提供一种能够通过与压接针弹性连接的汇流插座,实现密集接点、可靠汇流。
本发明解决所述技术问题的技术方案是,设计一种基于铜基体插孔连接汇流插座,该插座包括基座、第一弹性接触体和第二弹性接触体,所述基座为铜铸造而成,其上表面并排设置有若干上孔,所述上孔内安装有第一弹性接触体。所述基座的一侧面的下半部分上设置有一个侧孔,所述侧孔内安装有第二弹性接触体。所述基座的底面上设置一个螺纹孔,用于插座的定位固定。所述上孔位于基座的上半部分,侧孔与螺纹孔位于基座的下半部分上,上孔、侧孔与螺纹孔互不连通。
与现有技术相比,本发明的优点在于设计、制造周期短,具有使用简单、维修方便的特点,避免了“一点多线的限用工艺”和助焊剂残留带来的隐患,提高了生产效率和加工可靠性。同时,具有可自由组合的特点,可实现快速应用。该发明操作简单,对工人技术要求不高,符合产品小型化的走向,具有很好的发展前景。

具体实施方式
以下将结合附图对本发明做进一步的说明,但不应以此来限制本发明的保护范围。
本发明提供一种基于铜基体插孔连接汇流插座,该插座包括基座、第一弹性接触体和第二弹性接触体,所述基座为铜铸造而成,其上表面并排设置有若干上孔,所述上孔内安装有第一弹性接触体。所述基座的一侧面的下半部分上设置有一个侧孔,所述侧孔内安装有第二弹性接触体。所述基座的底面上设置一个螺纹孔,用于插座的定位固定。所述上孔位于基座的上半部分,侧孔与螺纹孔位于基座的下半部分上,上孔、侧孔与螺纹孔互不连通。
实施例1
本实施例提供一种基于铜基体插孔连接汇流插座,该插座包括基座1、第一弹性接触体2和第二弹性接触体2,所述基座1为铜铸造而成,外形尺寸为14.2mmX10mmX5mm。其上表面并排设置有12个上孔11,分两排整齐布置,相邻两孔的中心距为2.2mm,上孔11间距可保证两者0.2mm导线的安装。
所述上孔11内安装有第一弹性接触体2,所述第一弹性接触体2的直径为1mm。所述基座1的一侧面的下半部分上设置有一个侧孔12,所述侧孔12的中心位置距离下底面2.5mm,且其中心点位于该侧面的纵向中心线上。所述侧孔12内安装有第二弹性接触体3,所述第二弹性接触体3的直径为2.5mm。所述基座1的底面上设置一个螺纹孔13,用于插座的定位固定。所述上孔11位于基座1的上半部分,侧孔12与螺纹孔13位于基座的下半部分上,上孔11、侧孔12与螺纹孔13互不连通。
所述上孔11为小电流插孔,可满足单孔2A~5A载流能力,满载为24A~60A;侧孔12为大电流插孔,可满足20~40A载流能力。
每个插孔单点脱出力不小于55g,接触电阻不大于100mΩ。
螺纹孔13选择M4的螺纹孔,深度不小于4mm。
所述第一弹性接触体2、第二弹性接触体3为镀金材质,可以根据需要与厂家进行沟通选择,弹性接触体与导线压接之后直接插入汇流插座中,靠适配的弹性卡簧进行固定,必要时可以使用一些环氧胶。
本发明插座可直接螺钉安装在绝缘体上单体使用,需要更大电流汇流时,还可通过安装在金属结构件上或采用短路铜片并联使用。还能够与插孔连接的插针通过坑压式压接与导线连接,可以快速连接,实现密集接点、可靠汇流。
本发明的工作原理是用压接的方式实现大电流的汇流,其工作流程是将导线与压接针固定,再将连有导线的压接针放入汇流插座中,必要时可以使用一些环氧胶进行固定(如ergo5881、ergo1690等),然后将整个汇流插座用螺钉固定在玻璃布板或其他绝缘体上,以实现汇流功能。
本发明主要通过采用整体铜材为基体,实现大电流汇流,并一侧精准钻孔后在孔内装入适配的弹性卡簧,方便与导线压接针实现可靠连接,从而达到可靠汇流的目的,具有使用、维修方便的特点,回避了“一点多线的限用工艺”和助焊剂残留带来的隐患,提高了生产效率和加工可靠性。
现在的产品逐步走向小型化,机箱内强电舱的大电流汇流大多靠焊接实现,焊接的方式后续存在一定风险。本发明插座使用于空间狭小、导线较多的产品,提高了产品的可靠性,降低了生产成本。
本发明未述及之处适用于现有技术。
