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上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, 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, 由于螺紋的咬合作用, 在旋拧外连接帽时, 内连接螺帽会继续移向 插座, 当插头与插座插合到位后, 内连接螺帽上的配合键的前部分移动到传动 键的前方, 传动键处于容纳环槽内, 传动键不再与配合键啮合, 即便是继续旋 转外连接帽, 内连接螺帽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己经插合到位。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与内连接螺帽的配合键的后部分咬合,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 传动键与配合键的前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。 The front part of the plug housing of the present invention has an inner connecting nut, and the inner connecting nut is axially disposed on the plug housing, and the sliding sleeve on the outer peripheral surface of the inner connecting nut is provided with an anti-off setting. The outer connecting cap on the nut rotates the outer connecting cap when the plug is connected to the socket, and the outer connecting cap is driven by the cooperation between the driving key on the inner peripheral surface and the mating key on the outer peripheral surface of the inner connecting nut The inner connecting nut rotates and cooperates with the external thread of the socket housing, and the inner connecting nut drives the plug and the socket to be inserted, and pushes the outer connecting cap forward, and the front end of the outer connecting cap cooperates with the top pressing structure of the socket housing The rear outer connecting cap is no longer moved to the socket. Due to the snapping of the thread, when the outer connecting cap is screwed, the inner connecting nut will continue to move to the socket. When the plug and the socket are inserted into position, the inner connecting nut is matched. The front part of the key moves to the front of the drive key, the drive key is in the accommodating ring groove, the drive key is no longer engaged with the mating key, even if the outer connecting cap continues to rotate, the inner connecting nut will not continue to move to the socket, the plug is inserted The insertion movement ends, at this time, due to the end of the insertion movement, the insertion force due to the insertion between the plug and the contact of the socket and the relative movement between the plug housing and the socket housing disappears, and the outer connecting cap is rotated. The force required is suddenly reduced, The operator can therefore determine that the plug and socket have been inserted into place. Even if the connector assembly is not visible, it is known that the connector assembly is already in place. When the connector assembly is disengaged, moving the outer connecting cap backward causes the transmission key of the outer connecting cap to engage with the rear portion of the mating key of the inner connecting nut, and the outer connecting cap is reversely rotated to move the inner connecting nut back a certain distance and then Push the outer connecting cap forward all the way to make the drive key and the front part of the mating key bite and rotate the outer connecting cap in reverse until the plug and the socket are completely separated.
本发明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。 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与内连接螺帽 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推 压力的情况下, 连接器组件没有插合到位时, 传动键一直会与配合键的前部分 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, 操作方 便, 也可以更好的保证插头与插座的可靠插合。  The outer connecting cap of the present invention is disposed on the inner connecting nut through the front retaining structure and the rear retaining structure, and the front retaining structure comprises a front limiting step surface disposed on the outer peripheral surface of the inner connecting nut and facing the front end. a rear limit step surface disposed on the inner circumferential surface of the outer connecting cap toward the rear end, the front limit step surface and the rear limit step surface are elastically press-fitted by the elastic pushing member disposed between the two, and the rear anti-off structure The limit retaining edge is assembled on the rear end of the inner hole of the outer connecting cap, and the limiting retaining edge is press-fitted with the rear end surface of the inner connecting nut. Due to the action of the elastic pushing member, the outer connecting cap does not move backward relative to the inner connecting nut without external force, that is, the outer connecting cap is not subjected to the backward pushing enough to overcome the elastic force of the elastic pushing member. In the case of pressure, when the connector assembly is not inserted into place, the transmission key will always engage with the front part of the mating key. Therefore, it is not necessary to push the outer connecting cap forward all the time during the insertion of the plug and the socket, and the operation is convenient. It can also better ensure the reliable insertion of the plug and the socket.

Loosen in a vibrating environment.
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幅前移与插. 座连接。  The outer connecting nut 21 is axially slidably sleeved with an outer connecting cap 20, and the outer connecting cap 20 is disposed on the inner connecting nut 21, and the outer peripheral surface of the inner connecting nut 21 is provided with a front limit toward the front end. The step surface, the inner peripheral surface of the outer connecting cap 20 is provided with a rear limiting step surface facing the rear end, and the front limiting step surface and the rear limiting step surface are limitedly engaged to prevent the outer connecting cap 20 from being connected by the inner connecting nut 21 The rear end of the outer connecting cap 20 is mounted with a hole retaining spring 17 at the rear end of the outer connecting cap 20, and the hole retaining cap 17 is engaged with the rear end surface of the inner connecting nut 21 to prevent the outer connecting cap 20 from being connected by the inner connecting nut. The front end of 21 is taken off. When the plug and the socket are inserted, the outer connecting cap 20 is moved by the cooperation between the retaining cap and the rear end surface of the inner connecting nut 21 to drive the inner connecting screw forward and the socket.
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, 配合键 31被 容纳环槽 32分为了前后两部分, 容纳环槽 32可以容纳下传动键 28。  A transmission key 28 is disposed on the circumferential surface of the inner hole of the outer connecting cap 20 in the circumferential direction, and the transmission key 28 extends in the axial direction. The outer peripheral surface of the inner connecting nut 21 is provided with a mating key 31 engaged with the transmission key 28, and the matching key The accommodated ring groove 32 is divided into front and rear portions, and the accommodation ring groove 32 can accommodate the lower drive key 28.
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与配合键 31的 前部分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, 传动键与配合键的前部分分离, 传动键进入容纳环槽内, 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。 The front portion of the socket housing 40 is provided with a pressing step structure formed by a pressing step surface 39 toward the front end. The pressing step surface 39 is press-fitted with the front end portion of the outer connecting cap 20 during the insertion of the plug and the socket. . When the plug is inserted into the socket, the outer connecting cap 20 is held so that the plug is close to the socket and pushes the outer connecting cap 20 forward while screwing the outer connecting cap 20, and the outer connecting cap 20 passes the transmission key 28 and the mating key 31. The cooperation between the front portions drives the inner connecting nut 21 to rotate, and pushes the inner connecting nut forward through the rear retaining structure between the front connecting nut 21 and the inner connecting nut 21 so that the inner connecting nut 21 is screwed to the socket housing. In the body, the plug and the socket enter the mating state under the pushing of the inner connecting nut, and the front end of the outer connecting cap is pressed against the pressing step surface 39 of the socket housing 40, and the outer connecting is performed as the insertion movement is deepened. The cap is no longer moved forward, only rotates. When the outer connecting cap is pressed against the top pressing step, the inner connecting nut will move forward relative to the outer connecting cap and continue to tighten with the socket housing. The relative movement distance between the cap and the outer connecting cap reaches one When quantifying, the drive key is separated from the front part of the mating key, and the drive key enters the accommodating ring groove. Even if the outer connecting cap continues to rotate, the inner connecting nut will not continue to rotate, and the plug and the socket are inserted into position.
作为上述实施例的改进, 传动键 28的后端具有向延伸的延伸段, 传动键 28 与传动键 28的延伸段被避让环槽 29分为了两部分,避让环槽 29可以容纳下配合 键 31的后部分。在插头插座的插合运动开始时, 传动键的延伸段会与配合键的 后部分啮合, 与传动键一起带动内连接螺帽转动。 当插头和插座插合到位后, 传动键处于容纳环槽内, 配合键的后部分处于避让环槽内, 传动键的后部分也 与配合键的后部分分离, 外连接帽不再带动内连接螺帽转动。孔用卡簧 17的固 定环槽 30设置传动键的延伸段上, 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延伸段上,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。  As a modification of the above embodiment, the rear end of the transmission key 28 has an extending extension, and the extension of the transmission key 28 and the transmission key 28 is divided into two parts by the avoidance ring groove 29, and the escape ring groove 29 can accommodate the lower engagement key 31. The latter part. At the beginning of the insertion movement of the plug and socket, the extension of the drive key engages with the rear portion of the mating key, which together with the drive key causes the inner connecting nut to rotate. When the plug and the socket are inserted into position, the transmission key is in the receiving ring groove, the rear part of the matching key is in the escape ring groove, and the rear part of the transmission key is also separated from the rear part of the matching key, and the outer connecting cap no longer drives the inner connection. The nut rotates. The fixing ring groove 30 of the hole circlip 17 is provided on the extension of the transmission key, so that the radial size of the hole circlip can be reduced, and at the same time, since the fixing ring groove is provided on the extension of the transmission key, the outer connecting cap is not required. The thickness is thickened to provide a fixed ring groove, which reduces the radial dimension of the entire plug.
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。  As an improvement of the above embodiment, between the front limiting step surface and the rear limiting step surface, an elastic pressing member 22 is provided on the outer circumferential surface of the inner connecting nut 21, and the front limiting step surface and the rear limiting step step are provided. The surface is elastically press-fitted by the elastic pressing member. Under the action of the elastic pressing member, the hole of the rear end of the inner hole of the outer connecting cap is also press-fitted with the rear end surface of the inner connecting nut by the retaining spring 17 . Thus, the outer connecting cap of the plug does not move backwards relative to the inner connecting nut, and the outer connecting cap is not pushed forward when the plug is inserted into the socket.
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。  The elastic pusher 22 has one or more corrugated springs, and a spacer is disposed between the adjacent two corrugated springs.
上述实施例中的弹性推压件也可以是普通的弹簧。  The elastic pushing member in the above embodiment may also be a common spring.
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 在外连接帽压縮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, 用于保护波纹簧片, 防止其 因被过度压缩而失效。  As a modification of the above embodiment, the front end portion of the outer connecting cap 20 has an inturned end edge 23, and the end edge 23 is rearwardly connected to the inner connecting nut when the outer connecting cap compressing the corrugated spring is moved rearward relative to the inner connecting nut The face fit prevents the end edge 23 from being excessively compressed to protect the corrugated spring from failure due to excessive compression.
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延伸段。  The limit stop in the above embodiment is a circlip for the hole, and may also be a stop screwed to the rear end of the inner hole of the outer connecting cap. In this case, the extension of the transmission key may not be provided.
当插头与插座的接触件为多个时, 为了保护插头和插座的接触件, 在插头 壳体 15外周面的前端部设置有防误插键 27, 防误插键 27为 5个, 布设在插头壳 体的外周面上,防误插键 27在插头与插座插合时与插座壳体的内孔壁上设置的 防误插键槽配合。 When the plug and the socket have a plurality of contacts, in order to protect the plug and the socket contact, the plug The front end portion of the outer peripheral surface of the casing 15 is provided with an anti-missing key 27, and five anti-missing keys 27 are disposed on the outer peripheral surface of the plug housing, and the anti-missing key 27 is inserted into the socket and the socket. The anti-missing keyway provided on the inner wall of the body cooperates.
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, 传动键移至容纳环槽内, 配合键的后部分移至避让环槽内, 传动键与配合键的前部分分离, 传动键的延 伸段与配合键的后部分分离, 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与配合键的后部分咬合, 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与配合键的后 部分啮合, 旋转外连接帽, 使内连接螺帽向后退一定的距离, 放幵外连接帽, 在弹性推压件的作用下, 外连接帽相对于内连接螺帽前移, 传动键与配合键的 前部分自然啮合, 继续旋转外连接帽即可将插头与插座分离。在这里, 外连接 帽的前端是在螺纹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。  When the preferred embodiment of the above technical solution is inserted, the plug is inserted into the socket, and the outer connecting cap is rotated. The hole of the outer connecting cap is pushed by the circlip to push the inner connecting nut to move the plug forward, and the outer connecting cap is rotated at the same time. The connecting cap drives the inner connecting nut to rotate by the matching drive of the transmission key and the mating key, so that the screw is rotated on the socket housing, and the front end of the outer connecting cap is pressed against the pressing step surface no longer before the insertion is deepened. Move, the inner connecting nut continues to move forward relative to the outer connecting cap. When the plug is in place, the transmission key moves into the receiving ring groove, and the rear part of the matching key moves into the avoiding ring groove, the front part of the transmission key and the mating key Separating, the extension of the drive key is separated from the rear portion of the mating key, and the inner connecting nut no longer rotates with the outer connecting cap. In actual engineering, since the parts of the plug are not rigid bodies, when the plug and the socket are inserted into position, the inner connecting nut does not move forward with respect to the outer connecting cap as the outer connecting cap rotates, but when the outer connecting cap is reversed When the inner connecting nut rotates with the outer connecting cap and is separated from the socket housing, in order to prevent this, the inner connecting nut does not rotate with the outer connecting cap and moves forward relative to the outer connecting cap, Pushing the outer connecting cap to move back against the elastic force of the elastic pushing member and causing the driving key to engage with the rear portion of the mating key, while rotating the outer connecting cap to move the inner connecting nut forward by a smaller distance, and then placing When the outer cap is opened, the drive button and the mating button are completely disengaged. The inner connecting nut will not rotate with the outer connecting cap. When the plug and the socket need to be separated, the outer connecting cap can be pulled back. Engage the transmission key with the rear part of the mating key, rotate the outer connecting cap, and make the inner connecting nut retreat a certain distance, and release the outer connecting cap, under the action of the elastic pushing member, the external connection The cap nut with respect to the forward connection, the front portion of the drive key engages with a mating key nature, continued rotation of the outer cap is connected to the plug and the receptacle separated. Here, the front end of the outer connecting cap is in contact with the pressing step surface after the thread is engaged with a part, or it can be matched with the pressing step surface at the beginning, but only after the plug and the socket are completely inserted, the inner connecting The distance between the rear end of the nut and the circlip of the hole is larger, and the compression amount of the corresponding elastic urging member is also larger.
