Description
技术领域
本发明涉及一种车辆救援用的工具，特别是涉及一种汽车带夹电瓶搭火装置。
背景技术
汽车作为交通工具保有量巨大，电池是汽车必备的部件，为车辆启动和设备提供电能，电池也有失效时候，这时将无法启动汽车只能救援，救援的时候一般都是通过带夹子的电瓶搭火线，将另一电瓶的电源导入到失效电池端子处用于启动，由于启动电流较大，所以要求导线够粗，夹子与端子要接触良好，导线做出一些比较好实现，夹子都是硬性材料，所以夹持时接触面都是多个点接触或线接触，接触部位电阻较大，用打火造成接触不良，仍有待于进一步的加以解决。
发明内容
为了解决上述问题，本发明提供了一种汽车带夹电瓶搭火装置。
本发明采用的技术方案为：一种汽车带夹电瓶搭火装置，其特征在于包括夹头和与夹头连接的线缆，夹头由中部通过铰接轴铰接在一起的左支臂和右支臂，左支臂和右支臂后端分别为执手，两执手间设有将两执手施力分开的压缩弹簧，左支臂和右支臂前端分别连接有弧形夹片，两弧形夹片弧心相对，两弧形夹片轴线的方向与铰接轴方向垂直，线缆的芯是由30以上根金属丝构成的软芯，软芯在线缆端头分为三股，其中两股与夹头的左支臂和右支臂的执手后端分别连接，第三股端头设有箍。
进一步的，所述第三股横截面为软芯总横截面积的三分之一直三分之二。
本发明使用时将第三股密集螺旋缠绕到接线柱上，然后按压两执手使两弧形夹片张开，夹到缠绕第三股的接线柱上，第三股与接线柱接触紧密，接触面积大大的增加了，同时第三股直接与弧形夹片接触导电，电流经过第三股、两弧形夹片至左支臂和右支臂再至另两股后汇合，分多路传送接触电阻很小。
附图说明
图1为本发明实施例整体透视示意图。
附图标记:1线缆；2铰接轴；3左支臂；5其中两股；4右支臂；6压缩弹簧；7弧形夹片；8第三股；9箍。
具体实施方式
本发明实施例如图1所示，该汽车带夹电瓶搭火装置设有夹头和与夹头连接的线缆1，夹头由中部通过铰接轴2铰接在一起的左支臂3和右支臂4，左支臂和右支臂后端分别为执手，两执手间设有将两执手施力分开的压缩弹簧6，左支臂和右支臂前端分别连接有弧形夹片7，两弧形夹片弧心相对，两弧形夹片轴线的方向与铰接轴方向垂直，左支臂和右支臂后、弧形夹片均为导体，线缆为护套多芯软线，线缆的芯是由30以上根金属丝构成的软芯，软芯在线缆端头分为三股，其中两股5与夹头的左支臂和右支臂的执手后端分别连接，第三股8端头设有箍9，防止松散。
本发明使用时将第三股密集螺旋缠绕到接线柱上，然后按压两执手使两弧形夹片张开，夹到缠绕第三股的接线柱上，第三股与接线柱接触紧密，接触面积大大的增加了，同时第三股直接与弧形夹片接触导电，电流经过第三股、两弧形夹片至左支臂和右支臂再至另两股后汇合，分多路传送接触电阻很小。
实施时，可将第三股横截面设为软芯总横截面积的三分之一直三分之二，更符合电流分配大小。
综上所述仅为本发明较佳实施例，凡依本申请所做的等效修饰和现有技术添加均视为本发明技术范畴。
