具有连接到位手感的连接器组件及其插头
技术领域
本发明涉及一种用于传递电流或信号的连接器组件，尤其涉及一种通过连 接螺帽进行锁紧并在连接到位时具有连接到位手感的连接器组件， 同时， 本发 明还涉及该连接器组件的插头。
背景技术
在连接器领域， 当相互插合的连接器组件应用在具有震动的环境中时， 插 头很容易在从插座上脱落， 造成电流或信号的中断， 为了使插头与插座连接可 靠，现有的一种圆形连接器组件采用连接螺帽将插头和插座锁紧以防止插头和 插座脱开， 保证两者连接的可靠性， 如图 1~4所示， 一种采用连接螺帽锁紧的 连接器组件的插头， 该插头包括插头壳体 5， 插头壳体 5内具有贯通壳体前后的 内孔， 插头壳体 5的内孔通过绝缘部件 2固定设置有插头接触件 1 , 插头与插座 插合的一端为前端， 插头壳体 5外周面的前部转动套设有轴向限位设置在插头 壳体上的连接螺帽 4，连接螺帽 4内孔的前段具有用于与插座外周面前部设置的 外螺纹配合的内螺纹。 连接螺帽与插头壳体之间设置有螺纹防松结构 3， 螺紋 防松结构 3包括固定设置在插头壳体 5外周面上的固定齿圈 6， 固定齿圈 6的内周 面上设置有向内悬伸的卡爪 11， 卡爪 11卡装在插头壳体 5的外周面上设置在环 槽内实现固定齿圈 6在插头壳体 5上的轴向固定， 固定齿圈 6的内周面上还设置 有与插头壳体 5的外周面上设置的止转键配合止转的止转键槽 12， 固定齿圈 6的 前端面与连接螺帽 4的内孔壁上向内凸设的定位环的后侧面顶压配合实现连接 螺帽 4在插头壳体 5上的后端限位，定位环的前侧面与插头壳体的外周面上设置 的凸起的轴环的顶压配合，连接螺帽 4通过其定位环与插头壳体 5上的轴环与固 定齿圈 6之间的顶压配合轴向限位设置在插头壳体 5上。 连接螺帽 4的内孔的后 段滑动止转设置有活动齿圈 7， 活动齿圈 7的外周面上设置有与连接螺帽 4的内 孔壁上设置的键槽滑动配合的导向键 9， 活动齿圈 7的前端面与连接螺帽的定位 环的后侧面通过波纹弹簧 8弹性顶压配合。活动齿圈 7的后端面上设置有三角形 的端齿， 固定齿圈 6的后端设置有外翻的翻沿 13， 翻沿 13的前端面上设置有与 活动齿圈上的端齿 10咬合的端齿， 在转动连接螺帽 4时， 连接螺帽带动活动齿 圈转动， 由于活动齿圈与固定齿圈的端齿是三角形的， 固定齿圈的端齿会推压 活动齿圈使得活动齿圈压缩波纹弹簧 8前移， 活动齿圈的端齿 10与固定齿圈的 端齿错位， 使得连接螺帽得以转动， 防松结构使连接螺帽要在一定的扭矩下才 能转动， 可以防止连接螺帽与插座之间的螺紋连接在震动环境中松脱。在插头 插座插合时， 旋拧连接螺帽 4， 连接螺帽 4的螺紋与插座壳体的螺紋进入配合， 在连接螺帽的推动下， 插头向插座移动并与插座插合， 为了确保插头和插座插 合到位， 在插座的外周面上设置有色带， 当连接螺帽将色带完全遮盖就表明插 头和插座已经插合到位，但是当连接器组件使用在黑暗场合或是无法观察到连 接器的狭小空间中时， 就无法用眼睛观察方式判断连接器是否连接到位了。 发明内容
本发明的目的在于提供一种具有连接到位手感的连接器组件， 以解决现有 技术中当采用螺紋结构锁紧的连接器组件应用在黑暗场合或是无法观察到连 接器的狭小空间中时无法判断插头与插座是否已经连接到位了的问题， 同时， 本发明的目的还在于提供该连接器组件的插头。
为实现上述目的，本发明的具有连接到位手感的连接器组件采用如下技术 方案： 一种具有连接到位手感的连接器组件， 包括插头和插座， 插头与插座通 过各自的前端相插合， 插头包括插头壳体， 插座包括插座壳体， 插头壳体的前 部转动套设有轴向限位设置在插头壳体上的内连接螺帽， 内连接螺帽的内孔前 段具有与插座壳体前段设置的外螺纹旋接的内螺纹， 内连接螺帽的外周轴向滑 动套设有防脱设置在内连接螺帽上的外连接帽，外连接帽的内周面上在周向上 设置有轴向延伸的传动键， 内连接螺帽的外周面上在周向上设置有在内连接螺 帽旋拧在插座壳体的过程中与传动键咬合传动的配合键，插座壳体的外周的前 部设置有在内连接螺帽与插座壳体旋装到位前与外连接帽的前端部顶压保证 内连接螺帽相对于外连接帽前移的顶压台阶结构，外连接帽的内周面上具有将 传动键分为前后两部分的在内连接螺帽与插座壳体旋拧到位后外连接帽与顶 压台阶结构顶压时容纳配合键的容纳环槽。
所述的外连接帽通过前防脱结构和后防脱结构防脱设置在内连接螺帽上， 前防脱结构包括设置在内连接螺帽外周面上的朝向前端的前限位台阶面与设 置在外连接帽内周面上的朝向后端的后限位台阶面，前限位台阶面与后限位台 阶面通过设置在两者之间的弹性推压件弹性顶压配合，后防脱结构包括装配在 外连接帽内孔后端的限位挡沿， 限位挡沿与内连接螺帽的后端面顶压配合。
所述的弹性推压件包括套设在内连接螺帽外周的一个以上的波纹簧片。 所述的外连接帽的前端部具有与内连接螺帽的前端面限位配合防止波紋 簧片过度压缩的端沿。
所述的内连接螺帽与插头壳体之间设置有螺纹防松结构。
本发明的具有连接到位手感的连接器组件的插头采用如下技术方案： 一种具有连接到位手感的插头， 插头的前端用于与适配的插座插合， 插头 包括插头壳体，插头壳体的前部转动套设有轴向限位设置在插头壳体上的内连 接螺帽， 内连接螺帽的内孔前段具有用于与插座壳体前段设置的外螺纹旋接的 内螺紋， 内连接螺帽的外周轴向滑动套设有防脱设置在内连接螺帽上的外连接 帽， 外连接帽的内周面上在周向上设置有轴向延伸的传动键， 内连接螺帽的外 周面上在周向上设置有在内连接螺帽旋拧在插座壳体的过程中与传动键咬合 传动的配合键，外连接帽的内周面上具有将传动键分为前后两部分的在内连接 螺帽相对于外连接帽前移与插座壳体旋拧到位后容纳配合键的容纳环槽。
所述的外连接帽通过前防脱结构和后防脱结构防脱设置在内连接螺帽上， 前防脱结构包括设置在内连接螺帽外周面上的朝向前端的前限位台阶面与设 置在外连接帽内周面上的朝向后端的后限位台阶面，前限位台阶面与后限位台 阶面通过设置在两者之间的弹性推压件弹性顶压配合，后防脱结构包括装配在 外连接帽内孔后端的限位挡沿， 限位挡沿与内连接螺帽的后端面顶压配合。 所述的弹性推压件包括套设在内连接螺帽外周的一个以上的波纹簧片。 所述的外连接帽的前端部具有与内连接螺帽的前端面限位配合防止波纹 簧片过度压缩的端沿。
所述的内连接螺帽与插头壳体之间设置有螺纹防松结构。
本发明的插头壳体的前部转动套装有内连接螺帽， 内连接螺帽轴向限位设 置在插头壳体上， 内连接螺帽的外周面滑动套设有防脱设置在内连接螺帽上的 外连接帽， 在插头与插座连接时， 旋动外连接帽， 外连接帽通过其内周面上的 传动键与内连接螺帽的外周面上的配合键之间的配合带动内连接螺帽转动并 与插座壳体的外螺纹配合， 内连接螺帽带动插头与插座插合， 在插合过程中一 直向前推压外连接帽，在外连接帽的前端与插座壳体的顶压台阶结构配合后外 连接帽不再移向插座， 由于传动键与配合键的咬合作用， 在旋拧外连接帽时， 内连接螺帽会继续沿螺纹旋转并移向插座， 当插头与插座插合到位后， 内连接 螺帽上的配合键移动到传动键的后部分的前方， 配合键位于传动键的两部分之 间的容纳环槽内， 传动键不再与配合键啮合， 即便是继续旋转外连接帽， 内连 接也不会继续移向插座， 插头插座的插合运动结束， 这时由于插合运动结束， 由于插头与插座的接触件之间的插合以及插头壳体与插座壳体之间相对移动 而产生的插合力消失， 旋转外连接帽所需的力骤然减小， 操作人员因此可以判 定插头和插座已经插合到位。即便是在看不到连接器组件的情况下也可以知道 连接器组件已经连接到位。 在连接器组件分离时， 向后移动外连接帽使得外连 接帽的传动键的前部分与内连接螺帽的配合键咬合， 反向旋转外连接帽使内连 接螺帽后移一定的距离然后再一直向前推压外连接帽，使得配合键与传动键的 后部分咬合并一直反向旋转外连接帽直至插头与插座彻底分离。
本发明的连接器组件的插头的外连接帽通过前防脱结构和后防脱结构防 脱设置在内连接螺帽上， 前防脱结构包括设置在内连接螺帽外周面上的朝向前 端的前限位台阶面与设置在外连接帽内周面上的朝向后端的后限位台阶面， 前 限位台阶面与后限位台阶面通过设置在两者之问的弹性推压件弹性顶压配合， 后防脱结构包括装配在外连接帽内孔后端的限位挡沿， 限位挡沿与内连接螺帽 的后端面顶压配合。 由于弹性推压件的作用， 在没有外力的作用下外连接帽不 会相对于内连接螺帽后移， 也就是说， 在外连接帽没有受到足以克服弹性推压 件的弹力的向后的退压力的情况下， 连接器组件没有插合到位时， 配合键一直 会与传动键的后部分咬合， 因此， 在插头与插座的插合过程中无需一直向前推 压外连接帽， 可以更好的保证插头与插座的可靠插合。

具体实施方式
一种具有连接到位手感的连接器组件的实施例， 在图 5〜14中， 包括可以相 互插合的插头与插座， 插头与插座相互插合的插合端为前端。插座包括插座壳 体 40， 插座壳体 40的贯通前后的内孔中通过绝缘部件固定设置有插座接触件， 插座壳体 40的外周面的前段具有外螺纹。插头包括插头壳体 15， 插头壳体 15的 前部转动套装有内连接螺帽 21， 内连接螺帽 21的内孔的前段具有与插座壳体 40 前端的外螺紋配合旋紧的内螺紋。内连接螺帽 21与插头壳体 15之间设置有螺纹 防松结构， 螺紋防松结构包括固定设置在插头壳体 15外周面上的固定齿圈 16， 固定齿圈 16的内周面上设置有向内悬伸的卡爪 36，卡爪 36卡装在插头壳体 15的 外周面上设置的环槽 24内实现固定齿圈 16在插头壳体 15上的轴向固定， 固定齿 圈 16的内周面上还设置有与插头壳体 15的外周面上设置的止转键 25配合止转 的止转键槽 37， 固定齿圈 16的前端面与内连接螺帽 21的内孔壁上向内凸设的定 位环 34的后侧面顶压配合实现内连接螺帽 21在插头壳体 15上的后端限位，定位 环 34的前侧面与插头壳体 15的外周面上设置的凸起的轴环 26的顶压配合， 内连 接螺帽 21通过其定位环与插头壳体 15上的轴环和固定齿圈 16之间的顶压配合 轴向限位设置在插头壳体 15上。内连接螺帽 21的内孔的后段滑动止转设置有活 动齿圈 18，活动齿圈 18的外周面上设置有与内连接螺帽 21的内孔壁上设置的导 向键槽 33滑动配合的导向键 38，活动齿圈 18的前端面与内连接螺帽 21的定位环 34的后侧面通过波紋弹簧 19弹性顶压配合。活动齿圈 18的后端面上设置有三角 形的端齿， 固定齿圈 16的后端设置有外翻的翻沿 35， 翻沿 35的前端面上设置有 与活动齿圈上的端齿咬合的端齿， 在转动内连接螺帽 21时， 内连接螺帽带动活 动齿圈转动， 由于活动齿圈与固定齿圈的端齿是三角形的， 固定齿圈的端齿会 推压活动齿圈使得活动齿圈压缩波纹弹簧 19前移，活动齿圈的端齿与固定齿圈 的端齿错位， 使得内连接螺帽得以转动， 防松结构使内连接螺帽要在一定的扭 矩下才能转动，可以防止在内连接螺帽与插座之间的螺纹连接在震动环境中松 脱。
内连接螺帽 21的外周轴向滑动套设有外连接帽 20，外连接帽 20防脱设置在 内连接螺帽 21上， 内连接螺帽 21的外周面上设置有朝向前端的前限位台阶面， 外连接帽 20的内周面上设置有朝向后端的后限位台阶面，前限位台阶面与后限 位台阶面限位配合， 防止外连接帽 20由内连接螺帽 21的后端脱下； 外连接帽 20 的内孔后端安装有孔用卡簧 17， 孔用卡簧 17与内连接螺帽 21的后端面限位配 合， 防止外连接帽 20由内连接螺帽 21的前端脱下。 在插头插座插合时， 外连接 帽 20通过卡簧与内连接螺帽 21的后端面之间的配合带动内连接螺帽前移与插 座连接。
外连接帽 20的内孔周面上沿圆周方向布设有传动键 28，传动键 28沿轴向延 伸， 内连接螺帽 21的外周面上设置有与传动键 28咬合的配合键 31， 传动键 28被 容纳环槽 29分为了前后两部分， 容纳环槽 29可以容纳下配合键 31。
插座壳体 40的前部设置有由朝向前端的顶压台阶面 39形成的顶压台阶结 构， 在插头与插座插合的过程中顶压台阶面 39与外连接帽 20的前端部顶压配 合。在将插头与插座插合时， 握住外连接帽 20使得插头靠近插座并一直向前推 压外连接帽 20， 同时旋拧外连接帽 20， 外连接帽 20通过传动键 28的后部分与配 合键 30之间的配合带动内连接螺帽 21转动，并通过其与内连接螺帽 21之间的后 防脱结构向前推压内连接螺帽使得内连接螺帽 21旋接在插座壳体上，在内连接 螺帽的推压下插头与插座进入插合状态， 随着插合运动的深入， 外连接帽的前 端顶压在插座壳体 40的顶压台阶面 39上， 外连接帽不再前移， 只进行旋转， 在 外连接帽一直与顶压台阶面顶压的情况下， 内连接螺帽会相对于外连接帽前移 并继续与插座壳体旋紧， 当内连接螺帽与外连接帽之间的相对移动距离达到一 定量时， 传动键的前部分与配合键分离， 配合键进入容纳环槽内， 即便外连接 帽继续旋转， 内连接螺帽也不会继续转动了， 这时插头与插座插合到位。
作为上述实施例的改进， 传动键 28的后部分延伸到外连接帽的后端面。孔 用卡簧 17的固定环槽 30设置传动键的后部分的后部，这样可以减小孔用卡簧的 径向尺寸， 同时由于固定环槽设置传动键的后部分的后部， 不需要将外连接帽 的厚度加厚以便设置固定环槽， 减小了整个插头的径向尺寸。
作为上述实施例的改进，在前限位台阶面与后限位台阶面之间设置有套装 在内连接螺帽 21的外周面上弹性推压件 22，前限位台阶面与后限位台阶面通过 弹性推压件弹性顶压配合， 在弹性推压件的作用下， 外连接帽内孔后端的孔用 卡簧 17也与内连接螺帽的后端面顶压配合。这样插头的外连接帽不会自行相对 于内连接螺帽后移， 在插头与插座插合时不用一直向前推压外连接帽。
弹性推压件 22具有一个以上的波紋簧片，相邻的两个波纹簧片之间设置有 垫片。
上述实施例中的弹性推压件也可以是普通的弹簧。
作为上述实施例的改进， 外连接帽 20的前端部具有内翻的端沿 23， 端沿 23 在外连接帽压缩波纹簧片相对于内连接螺帽后移的时与内连接螺帽的前端面 配合防止， 端沿 23可以防止波紋簧片被过度压缩， 用于保护波紋簧片， 防止其 因被过度压缩而失效。
以上实施例中的限位挡沿为孔用卡簧，也可以是螺纹旋接在外连接帽的内 孔后端的挡块， 这时， 可以不设置传动键的后部分不必延伸到外连接帽的后端 面。
在以上技术方案的最优实施例插合时，将插头插在插座上，转动外连接帽， 外连接帽的孔用卡簧推动内连接螺帽带动插头前移， 同时转动外连接帽， 外连 接帽通过传动键的后部分与配合键的配合传动带动内连接螺帽转动使得其旋 接在插座壳体上， 随着插合的深入， 外连接帽的前端顶压在顶压台阶面上不再 前移， 内连接螺帽相对于外连接帽继续前移， 当插合到位后， 配合键移至容纳 环槽内， 传动键的后部分移动与配合键的前方与配合键分离， 内连接螺帽不再 随着外连接帽转动。在实际工程中由于插头的各个零件都不是刚体， 当插头与 插座插合到位后， 内连接螺帽虽然不会随着外连接帽转动相对于外连接帽前 移，但当外连接帽反转时，内连接螺帽会随着外连接帽转动并与插座壳体分离， 为了防止这种情的发生，在内连接螺帽不随外连接帽转动并相对于外连接帽前 移后，可以向后推外连接帽使其克服弹性推压件的弹力后移并使得传动键的前 部分与配合键咬合， 同时旋转外连接帽使内连接螺帽再向前移动一个较小的距 离， 然后放开外连接帽， 这时， 传动键的后部分与配合键完全脱离， 不管怎样 旋转外连接帽， 内连接螺帽都不会随之转动， 当需要将插头和插座分离时， 可 以向后拉外连接帽使传动键的前部分与配合键的啮合， 旋转外连接帽， 使内连 接螺帽向后退一定的距离， 放开外连接帽， 在弹性件的作用下， 外连接帽相对 于内连接螺帽前移， 传动键的后部分与配合键自然啮合， 继续旋转外连接帽即 可将插头与插座分离。在这里， 外连接帽的前端是在螺紋啮合了一部分后才与 顶压台阶面接触的， 也可以一开始就与顶压台阶面配合， 只是这样， 在插头与 插座完全插合后， 内连接螺帽的后端与孔用卡簧之间的距离会大一些， 相应的 弹性推压件的压缩量也会大一些。
本发明的具有连接到位手感的插头的实施例， 在图 5〜1中， 结合图 12、 13、 14, 插头通过前端与适配的插座插合。插座包括插座壳体 40， 插座壳体 40的贯 通前后的内孔中通过绝缘部件固定设置有插座接触件，插座壳体 40的外周面的 前段具有外螺纹。插头包括插头壳体 15， 插头壳体 15的前部转动套装有内连接 螺帽 21， 内连接螺帽 21的内孔的前段具有与插座壳体 40前端的外螺紋配合旋紧 的内螺纹。 内连接螺帽 21与插头壳体 15之间设置有螺纹防松结构， 螺纹防松结 构包括固定设置在插头壳体 15外周面上的固定齿圈 16, 固定齿圈 16的内周面上 设置有向内悬伸的卡爪 36，卡爪 36卡装在插头壳体 15的外周面上设置的环槽 24 内实现固定齿圈 16在插头壳体 15上的轴向固定， 固定齿圈 16的内周面上还设置 有与插头壳体 15的外周面上设置的止转键 25配合止转的止转键槽 37， 固定齿圈 16的前端面与内连接螺帽 21的内孔壁上向内凸设的定位环 34的后侧面顶压配 合实现内连接螺帽 21在插头壳体 15上的后端限位，定位环 34的前侧面与插头壳 体 15的外周面上设置的凸起的轴环 26的顶压配合， 内连接螺帽 21通过其定位环 与插头壳体 15上的轴环和固定齿圈 16之间的顶压配合轴向限位设置在插头壳 体 15上。 内连接螺帽 21的内孔的后段滑动止转设置有活动齿圈 18， 活动齿圈 18 的外周面上设置有与内连接螺帽 21的内孔壁上设置的导向键槽 33滑动配合的 导向键 38，活动齿圈 18的前端面与内连接螺帽 21的定位环 34的后侧面通过波紋 弹簧 19弹性顶压配合。活动齿圈 18的后端面上设置有三角形的端齿， 固定齿圈 16的后端设置有外翻的翻沿 35，翻沿 35的前端面上设置有与活动齿圈上的端齿 咬合的端齿， 在转动内连接螺帽 21时， 内连接螺帽带动活动齿圈转动， 由于活 动齿圈与固定齿圈的端齿是三角形的， 固定齿圈的端齿会推压活动齿圈使得活 动齿圈压缩波紋弹簧 19前移， 活动齿圈的端齿与固定齿圈的端齿错位， 使得内 连接螺帽得以转动， 防松结构使内连接螺帽要在一定的扭矩下才能转动， 可以 防止在内连接螺帽与插座之间的螺紋连接在震动环境中松脱。
内连接螺帽 21的外周轴向滑动套设有外连接帽 20，外连接帽 20防脱设置在 内连接螺帽 21上， 内连接螺帽 21的外周面上设置有朝向前端的前限位台阶面， 外连接帽 20的内周面上设置有朝向后端的后限位台阶面，前限位台阶面与后限 位台阶面限位配合， 防止外连接帽 20由内连接螺帽 21的后端脱下； 外连接帽 20 的内孔后端安装有孔用卡簧 17， 孔用卡簧 17与内连接螺帽 21的后端面限位配 合， 防止外连接帽 20由内连接螺帽 21的前端脱下。 在插头插座插合时， 外连接 帽 20通过卡簧与内连接螺帽 21的后端面之间的配合带动内连接螺帽前移与插 座连接。
外连接帽 20的内孔周面上沿圆周方向布设有传动键 28，传动键 28沿轴向延 伸， 内连接螺帽 21的外周面上设置有与传动键 28咬合的配合键 31， 传动键 28被 容纳环槽 29分为了前后两部分， 容纳环槽 29可以容纳下配合键 31。
插座壳体 40的前部设置有由朝向前端的顶压台阶面 39形成的顶压台阶结 构， 在插头与插座插合的过程中顶压台阶面 39与外连接帽 20的前端部顶压配 合。在将插头与插座插合时， 握住外连接帽 20使得插头靠近插座并一直向前推 压外连接帽 20， 同时旋拧外连接帽 20， 外连接帽 20通过传动键 28的后部分与配 合键 30之间的配合带动内连接螺帽 21转动，并通过其与内连接螺帽 21之间的后 防脱结构向前推压内连接螺帽使得内连接螺帽 21旋接在插座壳体上，在内连接 螺帽的推压下插头与插座进入插合状态， 随着插合运动的深入， 外连接帽的前 端顶压在插座壳体 40的顶压台阶面 39上， 外连接帽不再前移， 只进行旋转， 在 外连接帽一直与顶压台阶面顶压的情况下， 内连接螺帽会相对于外连接帽前移 并继续与插座壳体旋紧， 当内连接螺帽与外连接帽之间的相对移动距离达到一 定量时， 传动键的前部分与配合键分离， 配合键进入容纳环槽内， 即便外连接 帽继续旋转， 内连接螺帽也不会继续转动了， 这时插头与插座插合到位。
作为上述实施例的改进， 传动键 28的后部分延伸到外连接帽的后端面。孔 用卡簧 17的固定环槽 30设置传动键的后部分的后部，这样可以减小孔用卡簧的 径向尺寸， 同时由于固定环槽设置传动键的后部分的后部， 不需要将外连接帽 的厚度加厚以便设置固定环槽， 减小了整个插头的径向尺寸。
作为上述实施例的改进，在前限位台阶面与后限位台阶面之间设置有套装 在内连接螺帽 21的外周面上弹性推压件 22，前限位台阶面与后限位台阶面通过 弹性推压件弹性顶压配合， 在弹性推压件的作用下， 外连接帽内孔后端的孔用 卡簧 17也与内连接螺帽的后端面顶压配合。这样插头的外连接帽不会自行相对 于内连接螺帽后移， 在插头与插座插合时不用一直向前推压外连接帽。
弹性推压件 22具有一个以上的波纹簧片，相邻的两个波紋簧片之间设置有 垫片。
上述实施例中的弹性推压件也可以是普通的弹簧。
作为上述实施例的改进， 外连接帽 20的前端部具有内翻的端沿 23， 端沿 23 在外连接帽压缩波纹簧片相对于内连接螺帽后移的时与内连接螺帽的前端面 配合防止， 端沿 23可以防止波纹簧片被过度压缩， 用于保护波紋簧片， 防止其 因被过度压缩而失效。
以上实施例中的限位挡沿为孔用卡簧，也可以是螺紋旋接在外连接帽的内 孔后端的挡块， 这时， 可以不设置传动键的后部分不必延伸到外连接帽的后端 面。
