具体实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图说明本发明的具体实施方式。在本发明的描述中，除非另有说明，“多个”的含义是两个或两个以上。
如图1至图11所示，公开了一种锁扣保持装置100和连接器组件。
如图1所示，本发明的锁扣保持装置100用于确保插头300和插座200的配合，锁扣保持装置100包括：
基体，基体具有框架部101，框架部101的两侧延伸有相对设置的连接部102，连接部102设置有成对的第一锁扣103，第一锁扣103用于将锁扣保持装置100固定并处于预装状态；框架部101还设置有引导基体与插头300、插座200中任一者配合的引导面104；以及
与框架部101连接的弹性臂105，弹性臂105的自由端设置有第二锁扣106，第二锁扣106用于在插头300与插座200对插后，将锁扣保持装置100固定并处于锁紧状态。
需要说明的是，本实施例中的锁扣保持装置100预先安装在插座200上，等待插头300与插座200对接后，再将插座200与插头300锁紧。当然，可以理解，在其他实施例中，锁扣保持装置可以预先安装在插头300上，等待插座与插头300对接后，再将插座与插头300锁紧。
由此，锁扣保持装置100设置有成对的第一锁扣103，以及位于弹性臂105自由端的第二锁扣106，其与插座200或插头300上的避让结构或突出结构匹配，可以实现锁扣保持装置100的预装，以及，实现通过锁扣保持装置100达到的插头300以及插座200的有效锁止。
具体地，如图1和图2所示，框架部101具有沿引导插入方向延伸且相对设置的第一框架部段107和第二框架部段108，相对设置的连接部102分别位于第一框架部段107和第二框架部段108的沿引导插入方向的后端。
需要说明的是，引导插入方向为锁扣保持装置100安装至插座200的过程中向插座200靠近的方向，也可以理解为是图4中箭头所示的引导插入方向。因此，引导插入方向的前端为靠近箭头一侧的端部，引导插入方向的后端为远离箭头一侧的端部。
更具体地，连接部102呈板状，自连接部102的外边缘向板内开设有凹槽以形成扣合臂109，第一锁扣103设置于扣合臂109上。由此，在锁扣保持装置100经由第一锁扣103安装至插座200上时，扣合臂109弹性形变，以使第一锁扣103与插座200上的凹部201配合。
继续参考图1，引导面104为第一框架部段107和第二框架部段108两者的沿引导插入方向的前端的至少部分装配表面110。由此，通过该引导面104可以将锁扣保持装置100顺利地预装到插座200上。
更具体地，如图1和图2所示，第一框架部段107和第二框架部段108的沿引导插入方向的后端之间还连接有握持段111，握持段111的外表面形成有防滑槽112。由此，在将锁扣保持装置100拉出插座200时，操作者的手指接触防滑槽112可以增大摩擦，使拉拽更省力。优选地，握持段111的与防滑槽112相反位置处还延伸有凸台面117，凸台面117用于在锁扣保持装置100处于锁紧状态时抵住插座200的解锁按键208。
优选地，防滑槽112沿引导插入方向呈阶梯状。优选地，如图2所示，握持段111相对于第一框架部段107和第二框架部段108的装配表面110凸伸形成手指勾扣部113。由此，更加方便操作者的手指勾扣住该手指勾扣部113。
返回参考图1，第一框架部段107和第二框架部段108的沿引导插入方向的前端之间还连接有第三框架部段114，弹性臂105从第三框架部段114的中间位置继续向前延伸而出。
具体地，弹性臂105包括朝背离装配表面110的方向倾斜延伸的第一悬臂段115，和弯折连接第一悬臂段115的第二悬臂段116，第二悬臂段116的末端设置所述第二锁扣106，第二锁扣106朝背离装配表面110的方向突出。由此，在将锁扣保持装置100预装到插座200后，第二锁扣106可以更好地与插头300的对应结构配合。
优选地，如图2所示，第一悬臂段115与框架部101之间呈预设角度β，预设角度β为160°-176°。在本实施例中，该预设角度β为171°。优选地，预设角度β可以在171°±5°的范围内。更优选地，预设角度β可以在171°±1°的范围内。预设角度β具体可以为160°、162°、165°、166°、169°、170°、172°、175°、176°等等。
接下来参考图3至图11，详细说明本发明另一方面提供的连接器组件，以及锁扣保持装置100预装、锁紧、拆卸过程。
本发明公开的一种连接器组件，包括相互插接的插头300和插座200，以及设置在插头300或插座200上的如上述任一实施例所述的锁扣保持装置100，插头300和插座200中的一者上设有两个相对设置的凹部201，凹部201与第一锁扣103卡接，以令锁扣保持装置100处于预装状态；插头300和插座200中的另一者上设置有凸起301，在插头300与插座200相互插接时，凸起301顶起第二锁扣106，在插头300与插座200 相互插接后，第二锁扣106越过凸起301并与凸起301卡合，以令锁扣保持装置100处于锁紧状态。
具体地，本发明公开的连接器组件是防水型连接器，尤其是低压电源连接器。可以理解，上述的锁扣保持装置100既可以适用于防水型连接器也可以适用于非防水型连接器。
低压电源连接器分为插头300和插座200两端连接器，本实施例中CPA组装在插座200上。因此，以插座200为例，如图3所示，插座200包括护套、端子二次锁机构202、大线径端子204、小线径端子205、防水圈203、大防水塞207、小防水塞206。
护套是一种塑胶胶壳，采用注塑加工方式。作为连接器本体，保护和固定端子，使之与外界绝缘的非金属件。护套对应5个孔位处设计有弹片，此设计对端子装入护套后起到一次锁作用，防止端子退出。
端子二次锁机构202采用注塑加工方式，是端子二次锁机构，主要目的为加强端子的一次自锁或者提供一种单独端子锁止力的机构。
大线径端子204和小线径端子205是实现电气连接的金属导体，采用冲压加工方式，接触部分表面镀锡，与导线采用压接方式组合。
防水圈203，即防水硅胶圈，护套中用于阻止液体渗入的橡胶结构件。
大防水塞207和小防水塞206，与大线径端子204和小线径端子205压接适配。是压接在电线绝缘皮阻止液体从连接器孔位渗入的橡胶结构件。
插座200和CPA的组装流程为：
第一步、两种电缆剥线后分别穿入两种不同的大小防水塞，即，大线径电缆对应大防水塞207，小线径对应小防水塞206。
第二步：两种不同线径端子与穿好防水塞的电缆分别进行压接。
第三步：防水圈203装入护套中。
第四步：端子二次锁机构202预装入护套中。
第五步：将压接好的带线的大、小线径端子分别装入护套对应孔位中。
第六步：端子二次锁机构202装入锁止位。
第七步：如图4和图5所示，首先CPA装入预装位，CPA由引导插入方向通过带有弹性臂105设计的第二锁扣106以及两侧边对称的引导面104装入插座200的护套中，此时，第一锁扣103与护套的凹部201形成干涉，整个装有预装位CPA的插座连接器组装完成。
CPA装入锁止(锁紧)位的过程：如图6至图8所示，将插头连接器头部经过引导槽插入插座连接器中，CPA的第二锁扣106被插头连接器的护套的凸起301顶开，此时弹性臂105变形向上走，离开插座200的护套凹槽止位面，再次按下CPA，CPA向前走，第二锁扣106钩住插头300的凸起301。因此，插头300与插座200组装到位，CPA最终锁止位组装到位。
CPA的凸台面117抵住插座200的解锁按键208，使其按压不动，非人为操作下无法将插头300与插座连接器解锁。有效保证稳定的信号以及电能传输。
插头与插座连接器分离流程：如图9至图11所示，首先需要将CPA从锁止位，通过手指勾扣部113拉至预装位。然后，通过按压插座200的解锁按键208即可将插头300与插座连接器分离。
根据本发明的锁扣保持装置100和连接器组件，通过两级锁扣结构以及引导面104的设计，实现了插头300与插座200之间有效锁止。
以上所述仅为本发明示意性的具体实施方式，并非用以限定本发明的范围。任何本领域的技术人员，在不脱离本发明的构思和原则的前提下所作的等同变化与修改，均应属于本发明保护的范围。
