如图1-图14所示，本申请提供一种连接器组件，包括：相互对插的插头1和插座2，插头1和插座2上设置对配卡接的锁扣装置3，锁扣装置3被配置为阻止插头1和插座2脱离；连接器组件还包括至少部分***到锁扣装置3中的锁扣保持装置4，锁扣保持装置4防止锁扣装置3被误触碰导致插头1和插座2的非预期脱离。As shown in Figures 1 to 14, the present application provides a connector assembly, including: a plug 1 and a socket 2 that are plugged into each other, and a locking device 3 for mating engagement is provided on the plug 1 and the socket 2, and the locking device 3 is configured to prevent the plug 1 and the socket 2 from being disengaged; the connector assembly also includes a locking retaining device 4 that is at least partially inserted into the locking device 3, and the locking retaining device 4 prevents the locking device 3 from being accidentally touched, resulting in unexpected disengagement of the plug 1 and the socket 2.
如图4-图7和图14所示，锁扣装置3的内部设置固定槽61，当插头1和插座2对插前，插座2和锁扣保持装置4可以实现预装配，固定槽61与锁扣保持装置4卡接，使锁扣保持装置4固定在第一状态。As shown in Figures 4-7 and 14, a fixing groove 61 is provided inside the locking device 3. Before the plug 1 and the socket 2 are plugged into each other, the socket 2 and the locking retaining device 4 can be pre-assembled, and the fixing groove 61 is engaged with the locking retaining device 4 to fix the locking retaining device 4 in the first state.
如图3、图11-图13所示，锁扣装置3包括压块51，当插头1和插座2对插后，压块51将锁扣保持装置4从固定槽61中脱离，使锁扣保持装置4能够被推入到第二状态。As shown in FIG. 3 and FIG. 11 to FIG. 13 , the locking device 3 includes a pressing block 51 . When the plug 1 and the socket 2 are plugged into each other, the pressing block 51 disengages the locking retaining device 4 from the fixing groove 61 , so that the locking retaining device 4 can be pushed into the second state.
本申请中，插座2与锁扣保持装置4可以实现预安装，预安装的锁扣保持装置4处于第一状态，具体的如图4所示。In the present application, the socket 2 and the lock retaining device 4 can be pre-installed, and the pre-installed lock retaining device 4 is in a first state, as specifically shown in FIG. 4 .
在插座2与插头1进行对插时，插头1和插座2通过锁扣装置3锁紧，防止插头1和插座2脱离。锁扣装置3上包括压块51，具体的可以是插头1的内部设有压块51，插头1与插座2对插的过程中，压块51给锁扣保持装置4一个向下的作用力，将锁扣保持装置4从固定槽61中脱出。进一步向前(如图1中所示左方为向前，右方为向后)推动锁扣保持装置4，此时的锁扣保持装置4起到锁定作用，达到了防止插头1和插座2受到外力作用时脱离的目的，此时锁扣保持装置4处于第二状态，具体如图13所示。When the socket 2 and the plug 1 are plugged in, the plug 1 and the socket 2 are locked by the locking device 3 to prevent the plug 1 and the socket 2 from being separated. The locking device 3 includes a pressing block 51, and specifically, the plug 1 is provided with a pressing block 51 inside. During the plug 1 and the socket 2 are plugged in, the pressing block 51 exerts a downward force on the locking retaining device 4 to disengage the locking retaining device 4 from the fixing groove 61. The locking retaining device 4 is further pushed forward (forward to the left and backward to the right as shown in FIG. 1 ), and the locking retaining device 4 at this time plays a locking role, achieving the purpose of preventing the plug 1 and the socket 2 from being separated when subjected to external force. At this time, the locking retaining device 4 is in the second state, as specifically shown in FIG. 13 .
本设计的结构，对插头1和插座2进行解锁，首先需要向后先退锁扣保持装置4，再进一步对锁扣装置3施加作用力，才能实现插头1和插座2的解锁脱离，属于双重解锁步骤，能够保证连接器的使用安全，另外，本申请还具有结构简单的特点，利于生产，可节约成本。According to the structure of the present design, to unlock the plug 1 and the socket 2, it is first necessary to retract the lock retaining device 4 backwards, and then further apply force to the lock device 3 to achieve the unlocking and disengagement of the plug 1 and the socket 2. This is a double unlocking step, which can ensure the safe use of the connector. In addition, the present application also has the characteristics of simple structure, which is conducive to production and can save costs.
具体的，如图1-图4所示，锁扣装置3包括卡接槽52和卡接弹片60，卡接弹片60包括卡接部63，插头1和插座2通过卡接部63与卡接槽52相互卡接而保持对插连接，防止插头1和插座2在外力的作用下脱离。在一实施方式中，卡接槽52设置在插头1和插座2其中一者上，卡接弹片60设置在插头1和插座2中另一者上。Specifically, as shown in FIGS. 1 to 4 , the locking device 3 includes a snap-in slot 52 and a snap-in spring piece 60, and the snap-in spring piece 60 includes a snap-in portion 63. The plug 1 and the socket 2 are snap-in connected to each other through the snap-in portion 63 and the snap-in slot 52 to prevent the plug 1 and the socket 2 from being separated under the action of external force. In one embodiment, the snap-in slot 52 is provided on one of the plug 1 and the socket 2, and the snap-in spring piece 60 is provided on the other of the plug 1 and the socket 2.
具体的如图8所示，锁扣保持装置4包括相互连接的基体10和插接臂20，插接臂20为两个，两个插接臂20的前端通过横梁21连接，在卡接弹片60上相对于卡接部63的一侧设置固定槽61(如图4、图13和图14所示)，在第一状态下，横梁21与固定槽61卡接。如图8-图10所示，具体的，横梁21容纳在固定槽61中，固定槽61限制锁扣保持装置4进一步向前推动，使锁扣保持装置4保持在第一状态。Specifically, as shown in FIG8 , the lock retaining device 4 includes a base 10 and a plug-in arm 20 connected to each other. There are two plug-in arms 20, and the front ends of the two plug-in arms 20 are connected by a crossbeam 21. A fixing groove 61 is provided on the side of the snap-on spring 60 relative to the snap-on portion 63 (as shown in FIG4 , FIG13 and FIG14 ). In the first state, the crossbeam 21 is snap-fitted with the fixing groove 61. As shown in FIG8 to FIG10 , specifically, the crossbeam 21 is accommodated in the fixing groove 61, and the fixing groove 61 limits the lock retaining device 4 from being pushed forward further, so that the lock retaining device 4 is kept in the first state.
在一实施方式中，如图4所示，横梁21的长度大于固定槽61的长度，横梁21的两端凸出于卡接弹片60两侧设置。 In one embodiment, as shown in FIG. 4 , the length of the cross beam 21 is greater than the length of the fixing slot 61 , and both ends of the cross beam 21 are protruded from both sides of the clamping spring piece 60 .
在一实施方式中，卡接槽52内相对设置有压块51，压块51上设置斜面53，当插头1和插座2插接时，斜面53与横梁21的两端抵接并将横梁21从固定槽61中推出。In one embodiment, a pressing block 51 is disposed opposite to the engaging groove 52 , and an inclined surface 53 is disposed on the pressing block 51 . When the plug 1 and the socket 2 are plugged in, the inclined surface 53 abuts against both ends of the beam 21 and pushes the beam 21 out of the fixing groove 61 .
例如，在图3和图4的示例中，卡接槽52内设有两个相对设置的压块51，在插头1和插座2插接的过程中，两个压块51的斜面53分别与横梁21的两端的顶面接触并向其施加向下的压力，使整个横梁21脱离固定槽61。For example, in the examples of Figures 3 and 4, two oppositely arranged pressure blocks 51 are provided in the snap-in groove 52. During the plug-in process of the plug 1 and the socket 2, the inclined surfaces 53 of the two pressure blocks 51 respectively contact the top surfaces of the two ends of the beam 21 and apply downward pressure thereto, so that the entire beam 21 is separated from the fixing groove 61.
在操作时，插头1和插座2插接过程中，压块51给锁扣保持装置4一个向下的作用力，压块51的斜面53与锁扣保持装置4抵接，将锁扣保持装置4从固定槽61中推出。进一步向前推动锁扣保持装置4，此时的锁扣保持装置4起到锁定作用，达到了防止插头1和插座2受到外力作用时脱离的目的，此时锁扣保持装置4处于第二状态，具体如图13所示。During operation, when the plug 1 and the socket 2 are plugged together, the pressing block 51 exerts a downward force on the lock retaining device 4, and the inclined surface 53 of the pressing block 51 abuts against the lock retaining device 4, pushing the lock retaining device 4 out of the fixing groove 61. The lock retaining device 4 is further pushed forward, and at this time, the lock retaining device 4 plays a locking role, achieving the purpose of preventing the plug 1 and the socket 2 from being separated when subjected to external force. At this time, the lock retaining device 4 is in the second state, as shown in FIG. 13 .
横梁21突出卡接弹片60的两侧设置，可以保证插头1和插座2插接时，压块51的斜面53与横梁21的两端抵接，保证横梁21顺利的脱离固定槽61。The cross beam 21 protrudes from both sides of the clamping spring 60 to ensure that when the plug 1 and the socket 2 are plugged in, the inclined surface 53 of the pressing block 51 abuts against both ends of the cross beam 21 to ensure that the cross beam 21 is smoothly separated from the fixing groove 61 .
在一实施方式中，如图13所示，卡接弹片60包括弹舌62，弹舌62的一端与卡接部63连接，另一端为悬臂状态，插接臂20上设置有至少一个止压块22，在第一状态下，凹槽32与凸起72配合卡接前，止压块22与卡接弹片60之间设置预定间隙；在第二状态下，凹槽32与凸起72配合卡接后，止压块22与弹舌62抵接。In one embodiment, as shown in Figure 13, the snap-in spring piece 60 includes a spring tongue 62, one end of the spring tongue 62 is connected to the snap-in portion 63, and the other end is in a cantilever state. At least one pressure stop block 22 is provided on the plug-in arm 20. In the first state, before the groove 32 and the protrusion 72 are engaged and engaged, a predetermined gap is set between the pressure stop block 22 and the snap-in spring piece 60; in the second state, after the groove 32 and the protrusion 72 are engaged and engaged, the pressure stop block 22 abuts against the spring tongue 62.
插头1和插座2处于锁定时，在锁扣保持装置4的作用下，止压块22与弹舌62抵接，防止弹舌62受到压力而产生向下的位移，防止弹舌62发生形变，进而避免插头1和插座2在非人为因素下而产生脱离的情况发生，此时锁扣保持装置4处于第二状态。When the plug 1 and the socket 2 are locked, under the action of the lock retaining device 4, the pressure stop block 22 abuts against the spring tongue 62 to prevent the spring tongue 62 from being displaced downward due to pressure and to prevent the spring tongue 62 from being deformed, thereby avoiding the plug 1 and the socket 2 from being separated due to non-human factors. At this time, the lock retaining device 4 is in the second state.
插头1和插座2解锁时，推动锁扣保持装置4，止压块22与弹舌62之间不再抵接，并预留一定的间隙，弹舌62重新回到悬臂状态，此时锁扣保持装置4处于第一状态；继续按压弹舌62，按压力使卡接弹片60整体受到向下的压力，使卡接弹片60与卡接槽52脱离，插头1和插座2解锁。When the plug 1 and the socket 2 are unlocked, the lock retaining device 4 is pushed, the stop block 22 and the spring tongue 62 are no longer in contact, and a certain gap is reserved, and the spring tongue 62 returns to the cantilever state. At this time, the lock retaining device 4 is in the first state; continue to press the spring tongue 62, and the pressing force causes the snap-fit spring piece 60 to be subjected to downward pressure as a whole, so that the snap-fit spring piece 60 is disengaged from the snap-fit groove 52, and the plug 1 and the socket 2 are unlocked.
在一实施方式中，如图8和图13所示，插接臂20上设置有止压块22，止压块22的厚度沿***方向逐渐减小，此设计有助于实现止压块22与弹舌62的无缝对接。In one embodiment, as shown in FIG. 8 and FIG. 13 , a pressure stop block 22 is provided on the plug-in arm 20 , and the thickness of the pressure stop block 22 gradually decreases along the insertion direction. This design helps to achieve seamless connection between the pressure stop block 22 and the spring tongue 62 .
在一实施方式中，如图8所示，锁扣保持装置4还包括固定部30，固定部30的形状为L型并对称设置在基体10的两侧；固定部30内表面与插接臂20的侧面围成引导槽31，引导槽31沿插头1和插座2***方向延伸。In one embodiment, as shown in Figure 8, the lock retaining device 4 also includes a fixing portion 30, which is L-shaped and symmetrically arranged on both sides of the base 10; the inner surface of the fixing portion 30 and the side surface of the plug arm 20 form a guide groove 31, and the guide groove 31 extends along the insertion direction of the plug 1 and the socket 2.
在一实施方式中，引导槽31包括相对设置的两个侧面和与侧面连接的底面，底面上设有至少一个凹槽32，插头1或插座2上相对设有与引导槽31配合的引导肋70，引导肋70上设置凸起72，在第二状态下，插头1或插座2与锁扣保持装置4通过凹槽32与凸起72卡接配合。 In one embodiment, the guide groove 31 includes two oppositely arranged side surfaces and a bottom surface connected to the side surfaces, at least one groove 32 is provided on the bottom surface, and a guide rib 70 that cooperates with the guide groove 31 is provided on the plug 1 or the socket 2. A protrusion 72 is provided on the guide rib 70. In the second state, the plug 1 or the socket 2 and the lock retaining device 4 are engaged with each other through the groove 32 and the protrusion 72.
在一实施方式中，引导槽31包括相对设置的两个侧面和与侧面连接的底面，底面上设有至少一个凹槽32，凹槽32的延伸方向垂直于***方向。In one embodiment, the guide groove 31 includes two side surfaces that are opposite to each other and a bottom surface connected to the side surfaces. The bottom surface is provided with at least one groove 32 , and an extending direction of the groove 32 is perpendicular to the insertion direction.
如图4所示，引导槽31和引导肋70配合方便锁扣保持装置4与插座2插接，引导槽31的两侧分别由固定部30的内表面和插接臂20的内表面围成墙体，通过墙体能够防止异物进入连接器中，起到防异物的效果。As shown in Figure 4, the guide groove 31 and the guide rib 70 cooperate to facilitate the plugging of the lock retaining device 4 with the socket 2. The two sides of the guide groove 31 are respectively surrounded by the inner surface of the fixing part 30 and the inner surface of the plug-in arm 20 to form a wall. The wall can prevent foreign matter from entering the connector, thereby achieving the effect of preventing foreign matter.
如图7、图10和图14可知，引导肋70上设置有圆弧形凸起72，当锁扣保持装置4被推至第二状态时，在止压块22与弹舌62配合的情况下，进一步的，通过凸起72和凹槽32的配合，使锁扣保持装置4保持在最终位置上。As can be seen from Figures 7, 10 and 14, an arc-shaped protrusion 72 is provided on the guide rib 70. When the lock retaining device 4 is pushed to the second state, under the condition that the pressure stop block 22 cooperates with the spring tongue 62, further, through the cooperation of the protrusion 72 and the groove 32, the lock retaining device 4 is maintained in the final position.
在一实施方式中，底面在接近横梁21的端部设置有引导斜面33。In one embodiment, a guiding slope 33 is provided on the bottom surface at an end close to the cross beam 21 .
在一实施方式中，底面在远离横梁21的端部设置有台阶34。In one embodiment, a step 34 is provided on the bottom surface at the end away from the crossbeam 21 .
当锁扣保持装置4与插座2预安装时，锁扣保持装置4处于第一状态下，引导斜面33起到引导作用与凸起72配合，继续推动锁扣保持装置4，凸起72和凹槽32的配合，锁扣保持装置4处于第二状态。When the lock retaining device 4 is pre-installed with the socket 2, the lock retaining device 4 is in the first state, the guide slope 33 plays a guiding role and cooperates with the protrusion 72 to continue pushing the lock retaining device 4, and the protrusion 72 and the groove 32 cooperate, and the lock retaining device 4 is in the second state.
当需要解锁时，反向推动锁扣保持装置4，锁扣保持装置4借用凹槽32的圆滑引导作用挤压凸起72，使锁扣保持装置4回到第一状态。When unlocking is required, the lock retaining device 4 is pushed in the reverse direction, and the lock retaining device 4 uses the smooth guiding effect of the groove 32 to squeeze the protrusion 72, so that the lock retaining device 4 returns to the first state.
锁扣保持装置4的端部设置有台阶34，在解锁反向推动锁扣保持装置4时，与引导肋70后面的台阶34相互配合，实现锁扣保持装置4的防退，避免脱出。A step 34 is provided at the end of the lock retaining device 4. When the lock retaining device 4 is pushed in the reverse direction for unlocking, it cooperates with the step 34 behind the guide rib 70 to prevent the lock retaining device 4 from retreating and falling out.
在一实施方式中，横梁21的厚度大于等于插接臂20前端的厚度。In one embodiment, the thickness of the cross beam 21 is greater than or equal to the thickness of the front end of the plug-in arm 20 .
横梁21的厚度设置为大于或等于插接臂20前端的厚度，有助于横梁21与固定槽61卡接，不易脱出。The thickness of the cross beam 21 is set to be greater than or equal to the thickness of the front end of the plug-in arm 20, which helps the cross beam 21 to be engaged with the fixing groove 61 and prevent it from slipping out.
在一实施方式中，如图10所示，插接臂20中还包括至少一个弯折部23，弯折部23两端的延伸方向呈设定的角度R。In one embodiment, as shown in FIG. 10 , the plug arm 20 further includes at least one bending portion 23 , and the extending directions of the two ends of the bending portion 23 are at a set angle R.
插接臂20包括弯折部23，保证插接臂20在自然状态下斜向上翘起，方便横梁21更好的置于固定槽61中，在没有外力的作用下，横梁21不易脱出，防止将锁扣保持装置4直接被推到第二状态。The plug-in arm 20 includes a bending portion 23 to ensure that the plug-in arm 20 tilts upward in a natural state, so that the crossbeam 21 is better placed in the fixing groove 61. In the absence of external force, the crossbeam 21 is not easy to fall out, preventing the lock retaining device 4 from being directly pushed to the second state.
弯折部23的两端呈预设角度，保证在第一状态下，横梁21与固定槽61成干涉状态，使横梁21紧贴固定部30的底部，增强固定效果。The two ends of the bending portion 23 are at a preset angle, ensuring that in the first state, the cross beam 21 and the fixing groove 61 are in an interference state, so that the cross beam 21 is closely attached to the bottom of the fixing portion 30, thereby enhancing the fixing effect.
在一实施方式中，角度R为160°-175°，具体的可以设定为160°、165°、170°、175°等。In one embodiment, the angle R is 160°-175°, and can be specifically set to 160°, 165°, 170°, 175°, etc.
在一实施方式中，固定部30的外表面上设置有至少一个加强筋35，加强筋35延伸的方向垂直于***方向。 In one embodiment, at least one reinforcing rib 35 is disposed on the outer surface of the fixing portion 30 , and the extending direction of the reinforcing rib 35 is perpendicular to the insertion direction.
如图8所示，加强筋35的设置既可以增加固定部30的强度，延长固定部30的强度，又可以在推动锁扣保持装置4的时候，可以增大摩擦力，方便操作。As shown in FIG. 8 , the provision of the reinforcing rib 35 can not only increase the strength of the fixing portion 30 and extend the strength of the fixing portion 30 , but also increase the friction force when pushing the lock retaining device 4 to facilitate operation.
在一实施方式中，引导肋70上分别贯穿设有至少一个长条孔73，长条孔73沿引导肋70的延伸方向设置。In one embodiment, at least one elongated hole 73 is formed through each of the guide ribs 70 , and the elongated hole 73 is disposed along an extending direction of the guide rib 70 .
如图14所示，当推动锁扣保持装置4时，通过引导斜面33的挤压作用，凸起72连同引导肋70向下发生形变，使锁扣保持装置4推动到第二状态，凸起72的挤压力消失，引导肋70恢复原状。长条孔73的设置，能够保证在解锁和锁定过程中，推动锁扣保持装置4时，省力的同时，减小锁扣保持装置4和引导肋70之间的摩擦，提高使用寿命。As shown in FIG14 , when the lock retaining device 4 is pushed, the projection 72 together with the guide rib 70 are deformed downward by the squeezing effect of the guide slope 33, so that the lock retaining device 4 is pushed to the second state, the squeezing force of the projection 72 disappears, and the guide rib 70 returns to its original state.
