本发明提供了一种电连接装置,如图1-图12所示,该电连接装置包括:插座连接器20和插头连接器60,插座连接器20包括插座外壳2,插头连接器60包括插头外壳6和锁止器8,插头外壳6的前端插接于插座外壳2;插座外壳2的外壁设有第一锁扣201; 插头外壳6设有第一扭杆机构601,第一扭杆机构601设有第一锁钩602,第一锁钩602卡接于第一锁扣201的前侧,以阻止插头外壳6相对于插座外壳2向后运动,并且第一扭杆机构601能够在外力作用下带动第一锁钩602脱离第一锁扣201;锁止器8设有第一凸台804,锁止器8与插头外壳6连接,第一凸台804能够阻止第一扭杆机构601在外力作用下活动。
将锁止器8向前推入到位后,如图6-图8所示,锁止器8的位置保持稳定,锁止器8上的第一凸台804使第一扭杆机构601保持稳定,从而使第一锁钩602被限定于第一锁扣201的前侧,插头外壳6无法相对于插座外壳2向后运动,两者之间保持锁止。解锁时,操作者施加外力以使锁止器8相对于插头外壳6运动,第一凸台804偏离第一扭杆机构601;然后,操作者对第一扭杆机构601施加外力,第一扭杆机构601带动第一锁钩602活动而脱离第一锁扣201,实现第一锁钩602与第一锁扣201解锁,插头外壳6可以相对于插座外壳2向后运动,将插头连接器60与插座连接器20断开。该电连接装置可以保障电连接的锁止与断开的安全,方便操作,结构比较简单,降低了制造成本。
在一实施方式中,锁止器8与插头外壳6通过阻尼结构80限位,阻尼结构80能够阻止第一凸台804偏离第一扭杆机构601,如图6-图8所示,锁止器8的位置在阻尼结构80的作用下保持稳定;操作者施加外力以克服阻尼结构80产生的阻力,可以使锁止器8相对于插头外壳6运动,从而使得第一凸台804偏离第一扭杆机构601。
如图1-图18所示,插座外壳2的外壁设有第二锁扣202;插头外壳6设有第二扭杆机构606,第二扭杆机构606设有第二锁钩603,第二锁钩603卡接于第二锁扣202的前侧,以阻止插头外壳6相对于插座外壳2向后运动,并且第二扭杆机构606能够在外力作用下带动第二锁钩603脱离第二锁扣202;锁止器8设有第二凸台805,阻尼结构80能够阻止第二凸台805偏离第二扭杆机构606,第二凸台805能够阻止第二扭杆机构606在外力作用下活动。
将锁止器8向前推入到位后,锁止器8上的第二凸台805使第一扭杆机构601保持稳定,第二锁钩603被限定于第二锁扣202的前侧,第二锁钩603和第一锁钩602均对插头外壳6的位置起到限定作用。解锁时,第一凸台804偏离第一扭杆机构601,第二凸台805偏离第二扭杆机构606,这时,操作者分别对第一扭杆机构601和第二扭杆机构606施加外力,使第一锁钩602脱离第一锁扣201,第二锁钩603脱离第二锁扣202,实现解锁。
该电连接装置分别操作第一扭杆机构601和第二扭杆机构606进行解锁,实现了二 次锁功能。高压互锁连接器在解锁时,互锁信号回路与功率回路断开时存在时间间隔,在解锁拔开的过程中,有可能会出现连接器带电拔开的现象。该电连接装置在解锁时,通过第一扭杆机构601和第二扭杆机构606实现两次解锁,将插头连接器60从适配的插座连接器20上拔脱,能够实现高压互锁与功率端子分步断开,从而避免带电拔开的现象,降低了接触件或连接器烧蚀、以及对车辆和操作者造成伤害的风险。第一扭杆机构601和第二扭杆机构606分别各自解锁实现二次分离,操作方便,其中一个出现损坏情况时,另外一个还能起保护作用,提高了锁止安全性。
阻尼结构80能够产生一定大小的阻力,以阻止锁止器8相对于插头外壳6向后侧运动,并且,操作者对锁止器8施加足够大的外力以克服阻尼结构80产生的阻力时,则可以驱动锁止器8运动。在一实施方式中,阻尼结构80包括设置于锁止器8的第一阻尼凸台801和设置于插头外壳6的第二阻尼凸台605,第一阻尼凸台801的后侧设有第一阻尼斜面8011,第二阻尼凸台605的前侧设有第二阻尼斜面6051。如图8所示,将锁止器8向前推入到位后,第一阻尼凸台801位于第二阻尼凸台605的前侧,锁止器8向后侧运动时,第二阻尼凸台605对第一阻尼凸台801产生阻力,从而阻止锁止器8向后侧运动,以使第一凸台804与第一扭杆机构601保持配合,第二凸台805与第二扭杆机构606保持配合。当第一阻尼斜面8011与第二阻尼斜面6051抵接时,操作者继续增大向后侧的外力,在第一阻尼斜面8011与第二阻尼斜面6051的导向作用下,锁止器8会产生变形,第一阻尼凸台801从第二阻尼凸台605上滑过,锁止器8继续向后侧运动,实现第一凸台804偏离第一扭杆机构601,第二凸台805偏离第二扭杆机构606。
通过阻尼结构80,使锁止器8在插头外壳6上的位置保持稳定,并且,操作者施加足够大的外力即可使锁止器8解锁,结构简单,连接安全可靠,且方便操作,制造成本较低。
如图2和图3所示,当插头连接器60与插座连接器20未插合时,锁止器8未推入到位,第一阻尼凸台801位于第二阻尼凸台605的后侧,第二阻尼凸台605能够阻止第一阻尼凸台801向前运动,对锁止器8进行限位。
如图19-图21所示,锁止器8的前端设有第一解锁凸台802,插座外壳2设有第二解锁凸台203,第二解锁凸台203能够通过第一解锁凸台802,推动第一阻尼凸台801与第二阻尼凸台605分离。具体地,插头连接器60与插座连接器20插合时,第二解锁凸台203推动第一解锁凸台802向上翘起,第一解锁凸台802带动第一阻尼凸台801向上运动,从而使第一阻尼凸台801能够从第二阻尼凸台605的后侧运动至其前侧。
进一步地,锁止器8具有解锁臂806,如图20和图21所示,第一解锁凸台802和第一阻尼凸台801均设置于解锁臂806,第一解锁凸台802设置于第一阻尼凸台801的前侧,插头连接器60与插座连接器20插合时,第二解锁凸台203推动第一解锁凸台802向上翘起,解锁臂806随着向上变形,从而带动第一阻尼凸台801向上运动,方便操作。该锁止器8结构比较简单,加工方便,尺寸比较小,有利于缩减该电连接装置的整体尺寸。
在一实施方式中,插头外壳6的后端设有限位凸台604,以限制锁止器8向后侧运动的范围。进一步地,锁止器8的后端设有限位凹槽803,如图3、图17和图21所示,限位凸台604对限位凹槽803进行限位,阻止锁止器8向后侧运动。当插头连接器60与插座连接器20未插合时,通过限位凸台604和第二阻尼凸台605,将锁止器8的位置限定在设定范围内。
如图9所示,第二锁钩603设置于第一锁钩602的前侧,第二锁扣202位于第一锁扣201的前侧。在一实施方式中,第二锁钩603与第一锁钩602之间的距离,大于第二锁扣202与第一锁扣201之间的距离,当第一锁钩602与第一锁扣201抵接时,第二锁钩603位于第二锁扣202的前侧且相距一段距离;当第一锁钩602与第一锁扣201被解锁且插头连接器60向后侧移动一段距离后,第二锁钩603与第二锁扣202抵接,两者配合锁紧;操作者继续对第二扭杆机构606进行解锁操作,第二锁钩603与第二锁扣202解锁。该电连接装置中,第一级解锁步骤与第二级解锁步骤需要分步操作,解决了互锁信号回路与功率回路断开时的时间间隔问题,提高了安全性。
如图11-图18所示,第一锁钩602设置于第二锁钩603的内侧。第一锁钩602设置于第一扭杆机构601的前端,第一扭杆机构601的后端设置有第一按压部6011,操作者向内按压第一按压部6011,驱使第一扭杆机构601运动,并带动第一锁钩602向外侧运动,从而与第一锁扣201脱离;锁止器8的第一凸台804位于第一按压部6011的内侧时,可以阻止第一按压部6011受按压向内运动,从而使第一锁钩602与第一锁扣201保持锁定。
在一实施方式中,第一按压部6011的按压面面积大于等于5mm 2
如图12所示,手动按压第一按压部6011,使第一锁钩602与第一锁扣201脱离,并且拉动插头连接器60沿拔出方向移动,因此第一按压部6011的按压面面积需要能够承受人手指的力量,这个按压面最小面积为5mm 2,例如可以为2mm宽,2.5mm长的一个平面,能够保障用手指压下第一按压部6011。按压面的面积不能过大,过大容易在使 用过程中受到磕碰或按压,使第一按压部6011受到按压,导致第一锁钩602与第一锁扣201脱离,造成电路系统非预期中断。可以按照该电连接装置的整体尺寸,合理设计第一按压部6011按压面的面积大小。
为了验证第一按压部6011的按压面的面积大小对操作人员按压第一按压部6011的影响,发明人选用相同结构和大小的电连接装置的多组样件,各组样件中第一按压部6011的按压面的面积大小不同,共13组样件,每组100件样件,操作人员非连续分别按压第一按压部6011的按压面并使第一锁钩602与第一锁扣201脱离,记录操作人员一次操作成功率,并记录在表1中。在本实施例中,操作人员一次操作成功率小于95%为不合格。
表1:第一按压部6011的按压面的面积大小对操作人员按压第一按压部6011的影响
Figure PCTCN2022142645-appb-000001
从上表1可以看出,操作人员非连续地按压第一按压部6011的按压面并使第一锁钩602与第一锁扣201脱离,排除了人员疲劳度的影响,在按压按压面的面积大小不同的第一按压部6011时,当第一按压部6011的按压面的面积大于5mm 2的时候,都是可以操作成功;当第一按压部6011的按压面的面积等于5mm 2的时候,操作人员有3次失误,为97%,但是在合格值范围内;当第一按压部6011的按压面的面积小于5mm 2的时候,此时由于第一按压部6011的按压面的面积太小,操作人员的手指施力有困难,导致一次操作成功率降低,小于合格值范围。因此,发明人设定第一按压部6011的按压面的面积大于等于5mm 2
在一实施方式中,第一按压部6011受到第一按压力,驱使第一扭杆机构601运动,并带动第一锁钩602向外侧运动,从而与第一锁扣201脱离,优选地,第一按压力小于等于135N。
第一扭杆机构601具有一定的弹力,可以在第一按压部6011施加第一按压力的情况下,驱使第一扭杆机构601运动,并带动第一锁钩602向外侧运动,从而与第一锁扣201脱离,并且能够在自身的弹力作用下返回原位。如果第一扭杆机构601具有的弹力过大,导致需要施加很大的第一按压力才能使第一扭杆机构601变形,则当该电连接装 置需要解除一次锁止时,操作人员需要使用很大的力量才能使第一锁钩602与第一锁扣201脱离,费时费力,而且可能会对操作人员的手指造成一定的损伤。
为了验证第一按压力的大小对操作人员按压第一按压部6011的影响,发明人选用相同结构和大小的电连接装置的多组样件,各组样件中第一扭杆机构601的弹力大小不同,共13组样件,每组100件样件,操作人员非连续地分别按压第一按压部6011并使第一锁钩602与第一锁扣201脱离,记录操作人员一次操作成功率,并记录在表2中。在本实施例中,操作人员一次操作成功率小于95%为不合格。
表2:第一按压力的大小对操作人员按压第一按压部6011的影响
Figure PCTCN2022142645-appb-000002
从上表2可以看出,操作人员非连续地按压第一按压部6011并使第一锁钩602与第一锁扣201脱离,排除了人员疲劳度的影响,在按压不同弹力的第一按压部6011时,当第一按压力小于130N的时候,都是可以操作成功;当第一按压力为135N的时候,操作人员有4次失误,为96%,但是是在合格值范围内;当第一按压力超过135N的时候,此时由于第一按压力太大,操作人员的手指施力有困难,导致一次操作成功率降低,小于合格值范围。因此,发明人设定第一按压力小于等于135N。
第二锁钩603设置于第二扭杆机构606的前端,第二扭杆机构606的后端设置有第二按压部6061,操作者向内按压第二按压部6061,驱使第二扭杆机构606运动,并带动第二锁钩603向外侧运动,从而与第二锁扣202脱离;锁止器8的第二凸台805位于第二按压部6061的内侧时,可以阻止第二按压部6061受按压向内运动,从而使第二锁钩603与第二锁扣202保持锁定。
在一实施方式中,第二按压部6061的按压面的面积大于等于5mm 2
当电连接装置需要解除二次锁止时,需要手动按压第二按压部6061,使第二锁钩603与第二锁扣202脱离,并且拉动插头连接器60沿拔出方向移动,因此第二按压部6061需要一个按压面能够承受人手指的力量,这个按压面最小面积为5mm 2,例如可以为2mm宽,2.5mm长的一个平面,能够保障用手指压下按压面。按压面的面积不能过大,过大容易在使用过程中受到磕碰或按压,使第二按压部6061受到按压,导致第二锁钩603与第二锁扣202脱离,造成电路系统非预期中断。可以按照该电连接装置的整 体尺寸,合理设计按压面的面积大小。
为了验证按压面的面积大小对操作人员按压第二按压部6061的影响,发明人选用相同结构和大小的电连接装置的多组样件,各组样件中按压面的面积大小不同,共13组样件,每组100件样件,操作人员非连续分别按压不同按压面并使第二锁钩603与第二锁扣202脱离,记录操作人员一次操作成功率,并记录在表3中。在本实施例中,操作人员一次操作成功率小于95%为不合格。
表3:第二按压部6061按压面的面积大小对操作人员按压第二按压部6061的影响
Figure PCTCN2022142645-appb-000003
从上表3可以看出,操作人员非连续地按压不同按压面并使第二锁钩603与第二锁扣202脱离,排除了人员疲劳度的影响,在按压按压面的面积大小不同的第二按压部6061时,当按压面的面积大于5mm 2的时候,都是可以操作成功;当按压面的面积等于5mm 2的时候,操作人员有3次失误,为97%,但是在合格值范围内;当按压面的面积小于5mm 2的时候,此时由于按压面的面积太小,操作人员的手指施力有困难,导致一次操作成功率降低,小于合格值范围。因此,发明人设定第二按压部6061的按压面的面积大于等于5mm 2
在一实施方式中,第二按压部6061受到第二按压力,驱使第二扭杆机构606运动,并带动第二锁钩603向外侧运动,从而与第二锁扣202脱离,优选地,第二按压力小于等于135N。
为了验证第二按压力的大小对操作人员按压第二按压部6061的影响,发明人选用相同结构和大小的电连接装置的多组样件,各组样件中第二按压部6061的第二按压力大小不同,共13组样件,每组100件样件,操作人员非连续地分别按压第二按压部6061并使第二锁钩603与第二锁扣202脱离,记录操作人员一次操作成功率,并记录在表4中。在本实施例中,操作人员一次操作成功率小于95%为不合格。
表4:第二按压力的大小对操作人员按压第二按压部6061的影响
Figure PCTCN2022142645-appb-000004
从上表4可以看出,操作人员非连续地按压第二按压部6061并使第二锁钩603与第二锁扣202脱离,排除了人员疲劳度的影响,在按压不同第二按压力大小的第二按压部6061时,当第二按压力小于130N的时候,都是可以操作成功;当第二按压力为135N的时候,操作人员有3次失误,为97%,但是在合格值范围内;当第二按压力超过135N的时候,此时由于第二按压力太大,操作人员的手指施力有困难,导致一次操作成功率降低,小于合格值范围。因此,发明人设定第二按压力小于等于135N。
进一步地,第二扭杆机构606设有按压通孔6062,如图6-图8和图25所示;第一扭杆机构601设置于第二扭杆机构606的内侧,并且第一按压部6011设置于按压通孔6062中。第一扭杆机构601和第二扭杆机构606均设置于插头外壳6,第一扭杆机构601与第二扭杆机构606相互独立;锁止器8连接于插头外壳6,实现二次锁功能,结构比较简单,减少了零件数量,操作方便,连接安全可靠,且制造成本低。优选地,第一扭杆机构601、第二扭杆机构606与插头外壳6为一体结构。
在一实施方式中,插座连接器20和插头连接器60之间的插拔次数大于等于9次。
在高压连接装置装配时,需要将插座连接器20和插头连接器60装配到一起,后续维修、组件拆卸时,可能需要将插座连接器20和插头连接器60分离后再进行插拔,因此插座连接器20和插头连接器60之间的插拔次数不能小于9次,如果小于9次,可能在某次拆卸维修过程中,插座连接器20和插头连接器60受到损伤,无法起到连通电流的作用,导致需要将整个电连接装置包括线束全部更换,不仅耗费维修时间,也会增加维修成本,因此,无论从插座连接器20和插头连接器60的材料选择,还是插座连接器20和插头连接器60之间的插拔机构、锁死机构及密封机构的设计,都需要保障能够经历至少9次的拆卸组装,才能满足电连接装置的使用要求。
在一实施方式中,插头连接器60的重量小于等于305g。
一般情况下,插座连接器20固定在使用环境中,插头连接器60位于该电连接装置的上方且与插座连接器20插接固定,当插头连接器60的重量过大时,插座连接器20受到的重力也较大,在用电装置振动的情况下,会导致整个电连接装置跟随振动,由于惯性的原因,插头连接器60会受到较大的振动,会发出异响,而在电连接装置使用过程中,发生异响是不被允许的。
为了验证插头连接器60的重量对该电连接装置发生异响的影响,发明人采用相同的插座连接器20、不同重量的插头连接器60组装的电连接装置的样件,安装到振动试验台上,并进行振动试验,观察振动试验过程中插头连接器60是否发生异响,测试结 果如表5所示。
表5,插头连接器60的重量对该电连接装置发生异响的影响
重量(g) 265 275 285 295 305 315 325 335 345
是否异响
从表5可知,当插头连接器60的重量大于305g时,振动试验过程中,插头连接器60发生异响,测试不合格。所以发明人设定插头连接器60的重量小于等于305g。
在一实施方式中,插头连接器60沿插拔方向的高度小于等于208mm。
插座连接器20和插头连接器60装配到一起后,需要安装到用电环境中,但是一般情况下,用电环境预留的空间都较小,如果插头连接器60较高时,一是无法安装到用电环境当中,二是比较浪费原材料,因此插头连接器60在设计时需要低于一定的高度。
为了验证插头连接器60沿插拔方向的高度对该电连接装置安装情况的影响,发明人采用相同的插座连接器20、沿插拔方向的高度不同的插头连接器60组装的电连接装置的样件,安装到用电装置上,观察安装过程中,插头连接器60是否与用电环境其他零部件发生干涉,测试结果如表6所示。
从表6可知,当插头连接器60沿插拔方向的高度大于208mm时,无法安装到电连接装置的指定位置中,测试不合格。因此,发明人设定插头连接器60沿插拔方向的高度小于等于208mm。
表6,插头连接器60沿插拔方向的高度对电连接装置安装情况的影响
高度(mm) 168 178 188 198 208 218 228 238 248
是否干涉
该电连接装置的使用方法包括锁止步骤和解锁步骤。
锁止步骤包括:(1)插头连接器60与插座连接器20插合后,第二解锁凸台203将第一解锁凸台802顶起,此时第二限位凸台604对第一阻尼凸台801的限位作用消失,锁止器8能向前推动;(2)当锁止器8推动到位后,第一锁扣201与第一锁钩602配合锁紧;同时,第一凸台804顶住第一扭杆机构601的第一按压部6011,第二凸台805顶住第二扭杆机构606的第二按压部6061,使一级锁和二级锁无法解锁。
解锁步骤:(1)把锁止器8向后侧方向拉出;(2)按下第一按压部6011,并向后解锁插头连接器60,此时第一锁钩602和第一锁扣201解锁成功;(3)随着继续向后解锁插头连接器60,此时第二锁钩603和第二锁扣202配合锁紧;(4)按下第二按压部6061, 并继续向后解锁插头连接器60,此时第二锁钩603和第二锁扣202解锁。
在一实施方式中,插座外壳2设有至少两个导向柱204,如图19所示,第二锁扣202设置于导向柱204,第一锁扣201设置于至少两个导向柱204之间,如图19所示,两个导向柱204上分别设有第二锁扣202,两个第二锁扣202分布于第一锁扣201的两侧,插头外壳6上的第二锁钩603与两侧的第二锁扣202配合,提高了配合锁紧的可靠性。
考虑到在使用的过程中,插头连接器60与插座连接器20需要经常拔插,端子在拔插的过程中受力很容易脱落,当该定位结构失效时,会出现接触件脱出,导致连接器失效;而且,在使用的过程中,连接器会受到振动和摇摆,插头连接器60尾部的线束13存在长期偏摆的可能,加大了端子的受力,并存在漏水风险。为此,发明人对该电连接装置做了进一步地改进:插头外壳6中设有屏蔽外压接套11、屏蔽内压接套12和TPA卡环9,屏蔽外压接套11和屏蔽内压接套12压接于线束13的屏蔽层外,TPA卡环9套设于屏蔽外压接套11外,TPA卡环9与线束13上的屏蔽外压接套11、屏蔽内压接套12配合,起到端子防退的作用。
插头外壳6的后端连接有插头尾罩10,插头尾罩10中设有有尾部密封圈,尾部密封圈与插头外壳6配合,TPA卡环9、插头尾罩10、尾部密封圈、屏蔽外压接套11和屏蔽内压接套12相配合,限制尾部的线束13发生偏摆,避免了漏水风险。TPA卡环9在插头尾罩10前安装,TPA卡环9用于对屏蔽外压接套11、屏蔽内压接套12及线束13进行二次锁定,防止其松动。如图22所示,TPA卡环9设有卡环开口91,卡环开口91的宽度小于屏蔽外压接套11的直径,对线束13进行限定。插头尾罩10与尾部密封圈注塑到一起,尾部密封圈与插头外壳6配合,减少了零件数量,使成本降低,对线束13起到较好的限位作用,减小失效风险。
线束13连接于插头外壳6的后端,屏蔽外压接套11和屏蔽内压接套12套设于线束13外。如图1-图24所示,插座连接器20还包括连接于插座外壳2后端的密封胶垫1。插头连接器60还包括盖板3、插头绝缘体4、短接插针5和头座密封圈7,盖板3、插头绝缘体4、短接插针5和头座密封圈7均固设于插头外壳6内。插头连接器60可以按照一下步骤装配:
(1)将插头屏蔽套装在插头绝缘体4上;
(2)接着将短接插针5装到插头绝缘体4上;
(3)将组装好的插头绝缘体4装入插头外壳6;
(4)将头座密封圈7装入;
(5)将盖板3装上;
(6)将插头尾罩10套在线束上;
(7)将线束按需作剥线处理后,压接端子、屏蔽外压接套11和屏蔽内压接套12;
(8)将TPA卡环9装在压接好的线束上后,将线束组件装入插头连接器60。

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。
