在插座2与插头1进行对插时，插头1和插座2通过卡接槽52和卡接弹片60卡紧锁紧，防止插头1和插座2脱离。When the socket 2 is plugged into the plug 1 , the plug 1 and the socket 2 are locked together by the locking groove 52 and the locking spring 60 to prevent the plug 1 and the socket 2 from being separated.
按压卡接弹片60，使卡接槽52和卡接弹片60脱离卡接，位置保持装置4构造为相对于卡接弹片60可以移动到预装位置和保持位置；Press the snap-fit spring piece 60 to disengage the snap-fit groove 52 and the snap-fit spring piece 60, and the position holding device 4 is configured to be movable to the pre-installation position and the holding position relative to the snap-fit spring piece 60;
如图1-图13所示，在卡接弹片60上相对一侧设置容纳位置保持装置4的固定槽61。当插头1和插座2对插前，固定槽61与位置保持装置4卡接，使位置保持装置4固定在预装位置。As shown in Fig. 1 to Fig. 13, a fixing groove 61 for accommodating the position holding device 4 is provided on the opposite side of the snap-on spring piece 60. Before the plug 1 and the socket 2 are plugged together, the fixing groove 61 is snap-fitted with the position holding device 4, so that the position holding device 4 is fixed in the pre-installed position.
如图3所示，卡接槽52的两侧设置压块51，压块51上设置斜面53，当插头1和插座2对插后，压块的斜面53与位置保持装置4抵接，将位置保持装置4从固定槽61中推出。位置保持装置4进而从固定槽61中脱离，使位置保持装置4能够推入到如图12所示的保持位置。As shown in FIG3 , a pressing block 51 is provided on both sides of the clamping groove 52, and an inclined surface 53 is provided on the pressing block 51. When the plug 1 and the socket 2 are plugged into each other, the inclined surface 53 of the pressing block abuts against the position holding device 4, and the position holding device 4 is pushed out of the fixing groove 61. The position holding device 4 is then disengaged from the fixing groove 61, so that the position holding device 4 can be pushed into the holding position shown in FIG12 .
本发明，插座2与位置保持装置4可以实现预安装，预安装的位置保持装置4处于预装位置，具体的如图4所示。In the present invention, the socket 2 and the position retaining device 4 can be pre-installed, and the pre-installed position retaining device 4 is in a pre-installed position, as specifically shown in FIG. 4 .
插头1与插座2对插的过程中，压块给位置保持装置4一个向下的作用力，将位置保持装置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)推动位置保持装置4，位置保持装置4与卡接弹片60抵接防止卡接弹片60受到向下的压力而导致插头1和插座2脱离，此时的位置保持装置4起到锁定作用。During the process of plugging the plug 1 into the socket 2, the pressing block exerts a downward force on the position holding device 4, and the position holding device 4 is disengaged from the fixing groove 61. The position holding device 4 is further pushed forward (the left side is forward, and the right side is backward as shown in FIG. 1 ), and the position holding device 4 abuts against the engaging spring sheet 60 to prevent the engaging spring sheet 60 from being subjected to downward pressure, thereby causing the plug 1 and the socket 2 to be disengaged. At this time, the position holding device 4 plays a locking role.
插头1和插座2解锁时，首先需要向后先退位置保持装置4，正常的解锁步骤需要手动按压卡接弹片60，使卡接弹片60受力后产生向下的位移，从而实现插头1和插座2的解锁，但是在连接器比较小的情况下，直接手动按压卡接弹片60比较困难，所以此时设置辅助按压结构40，能够解决按压困难的问题，用较小的力作用在辅助按压结构40上，进一步作用在卡接弹片60上，就可以实现插头1和插座2的解锁，方便快捷。When the plug 1 and the socket 2 are unlocked, the position retaining device 4 needs to be retracted backwards first. The normal unlocking procedure requires manually pressing the latching spring piece 60 so that the latching spring piece 60 is displaced downward after being subjected to force, thereby unlocking the plug 1 and the socket 2. However, in the case of a relatively small connector, it is difficult to directly manually press the latching spring piece 60. Therefore, an auxiliary pressing structure 40 is provided at this time to solve the problem of difficult pressing. A smaller force is applied to the auxiliary pressing structure 40, and further applied to the latching spring piece 60, so that the plug 1 and the socket 2 can be unlocked conveniently and quickly.
本设计的结构，对插头1和插座2进行解锁时，需要向后先退位置保持装置4，再进一步对锁扣装置施加作用力，才能实现插头1和插座2的解锁脱离，双重的解锁步骤，能够保证连接器的使用安全，另外，本发明还具有方便操作的特点，利于装配和检修。According to the structure of the present design, when unlocking the plug 1 and the socket 2, it is necessary to first withdraw the position retaining device 4 backwards, and then further apply a force to the locking device to achieve the unlocking and disengagement of the plug 1 and the socket 2. The double unlocking steps can ensure the safe use of the connector. In addition, the present invention is also characterized by convenient operation, which is conducive to assembly and maintenance.
在一实施方式中，如图7-图9所示，位置保持装置4包括基体10和设置在基体10上的插接臂20，插接臂20为两个，两个插接臂20从基体10侧面沿位置保持装置4的 ***方向延伸，两个插接臂20的前端通过横梁21连接；辅助按压结构40的后端与基体10连接，辅助按压结构40的前端呈悬臂设置。In one embodiment, as shown in FIGS. 7-9 , the position holding device 4 includes a base 10 and a plug-in arm 20 disposed on the base 10. The plug-in arm 20 is two and the two plug-in arms 20 extend from the side of the base 10 along the position holding device 4. Extending in the insertion direction, the front ends of the two plug-in arms 20 are connected by a crossbeam 21; the rear end of the auxiliary pressing structure 40 is connected to the base 10, and the front end of the auxiliary pressing structure 40 is cantilevered.
具体的如图4所示，具体的为位置保持装置4的横梁21容纳在固定槽61中，固定槽61限制位置保持装置4进一步向前推动，使位置保持装置4保持在预装位置。Specifically, as shown in FIG. 4 , the crossbeam 21 of the position holding device 4 is accommodated in the fixing groove 61 , and the fixing groove 61 limits the position holding device 4 from being pushed further forward, so that the position holding device 4 is maintained at the pre-installed position.
如图9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。As shown in FIG. 9 , 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.
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，防止将位置保持装置4直接被推到保持位置。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 position holding device 4 from being directly pushed to the holding position.
弯折部23的两端呈预设角度，保证在预装位置时，横梁21与固定槽61成干涉状态，使横梁21紧贴固定槽61的底部，增强固定效果。The two ends of the bent portion 23 are at a preset angle, ensuring that the cross beam 21 and the fixing groove 61 are in an interference state when in the pre-installed position, so that the cross beam 21 is closely attached to the bottom of the fixing groove 61, thereby enhancing the fixing effect.
在一实施方式中，如图7所示，插接臂20与辅助按压结构40位于基体10的同侧。为了保证辅助按压结构40与卡接弹片60的位置相对应，辅助按压结构40在基体10底面平面的投影，处于两个插接臂20在基体10底面平面的投影之间。In one embodiment, as shown in Fig. 7, the plug arm 20 and the auxiliary pressing structure 40 are located on the same side of the base 10. In order to ensure that the auxiliary pressing structure 40 corresponds to the position of the clamping spring 60, the projection of the auxiliary pressing structure 40 on the bottom plane of the base 10 is between the projections of the two plug arms 20 on the bottom plane of the base 10.
在一实施方式中，插接臂20上设置有至少一个止压块22，横梁21与固定槽61卡接时，此时位置保持装置4保持在预装位置，止压块22与卡接弹片60之间设置预定间隙使二者之间保持一定的距离。止压块22的厚度沿***方向逐渐减小。止压块22位于卡接弹片60下方，与卡接弹片60抵接。In one embodiment, at least one stop block 22 is provided on the plug arm 20. When the cross beam 21 is engaged with the fixing groove 61, the position holding device 4 is maintained in the pre-installed position, and a predetermined gap is provided between the stop block 22 and the engaging spring sheet 60 so that a certain distance is maintained between the two. The thickness of the stop block 22 gradually decreases along the insertion direction. The stop block 22 is located below the engaging spring sheet 60 and abuts against the engaging spring sheet 60.
插头1和插座2处于锁定时，如图12所示，卡接弹片60推入到卡接槽52内时，此时横梁21与固定槽61脱离，在位置保持装置4的作用下，止压块22位于卡接弹片60的下方，并与卡接弹片60抵接，当按压卡接弹片60时，卡接弹片60被止压块22阻挡不能移动，防止卡接弹片60受到压力而产生向下的位移。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，此时位置保持装置4处于保持位置，插座2的上方有容纳辅助按压结构40的槽(未标号)，按压辅助按压结构40的前端容置在槽内呈保持状态。When the plug 1 and the socket 2 are locked, as shown in FIG12 , when the engaging spring piece 60 is pushed into the engaging groove 52 , the cross beam 21 is separated from the fixing groove 61 . Under the action of the position holding device 4 , the stop block 22 is located below the engaging spring piece 60 and abuts against the engaging spring piece 60 . When the engaging spring piece 60 is pressed, the engaging spring piece 60 is blocked by the stop block 22 and cannot move , preventing the engaging spring piece 60 from being displaced downward by pressure. This prevents the plug 1 and the socket 2 from being separated due to non-human factors. At this time, the position holding device 4 is in the holding position, and there is a groove (not numbered) above the socket 2 for accommodating the auxiliary pressing structure 40 . The front end of the auxiliary pressing structure 40 is held in the groove and is in a holding state.
插头1和插座2解锁时，推动位置保持装置4，止压块22与卡接弹片60之间不再抵接，有一定的间隙距离，此时卡接弹片60重新回到悬臂状态，此时位置保持装置4处于预装位置。When the plug 1 and the socket 2 are unlocked, the position holding device 4 is pushed, and the pressure stop block 22 and the engaging spring piece 60 are no longer in contact, and there is a certain gap distance. At this time, the engaging spring piece 60 returns to the cantilever state, and the position holding device 4 is in the pre-installed position.
按压辅助按压结构40时，辅助按压结构40和卡接弹舌62的上表面抵接，按压力使卡接弹片60整体受到向下的压力，辅助按压结构40带动卡接弹片60移动到能够使 卡接弹片60和卡接槽52脱离的位置，使卡接弹片60与卡接槽52脱离，插头1和插座2解锁。When the auxiliary pressing structure 40 is pressed, the auxiliary pressing structure 40 abuts against the upper surface of the clamping spring tongue 62, and the pressing force causes the clamping spring piece 60 to be subjected to downward pressure as a whole, and the auxiliary pressing structure 40 drives the clamping spring piece 60 to move to a position where it can be pressed. The engaging spring piece 60 and the engaging slot 52 are disengaged from each other, so that the engaging spring piece 60 is disengaged from the engaging slot 52 , and the plug 1 and the socket 2 are unlocked.
在一实施方式中，如图9所示，辅助按压结构40包括依次连接的倾斜部41、按压部42和接触部43，倾斜部41的一端与基体10连接，接触部43为自由端。In one embodiment, as shown in FIG. 9 , the auxiliary pressing structure 40 includes an inclined portion 41 , a pressing portion 42 , and a contact portion 43 connected in sequence, one end of the inclined portion 41 is connected to the base 10 , and the contact portion 43 is a free end.
具体的，当位置保持装置4位于预装位置时，止压块22与卡接弹片60具有设定的距离，按压按压部42时，接触部43与卡接弹片60上表面抵接，接触部43带动卡接弹片60移动到卡接弹片60和卡接槽52脱离的位置。Specifically, when the position holding device 4 is located in the pre-installed position, the pressure stop block 22 has a set distance from the snap-fit spring piece 60. When the pressing portion 42 is pressed, the contact portion 43 abuts against the upper surface of the snap-fit spring piece 60, and the contact portion 43 drives the snap-fit spring piece 60 to move to a position where the snap-fit spring piece 60 and the snap-fit groove 52 are disengaged.
倾斜部41从与基体10连接的一端，到与按压部42连接的一端，横截面积逐渐变小。插头1和插座2的插拔，需要对位置保持装置4进行多次按压，所以与基体10连接的一端需要保证一定的强度，另一端保证一定的弹性。The cross-sectional area of the inclined portion 41 gradually decreases from the end connected to the base 10 to the end connected to the pressing portion 42. The plug 1 and the socket 2 need to be plugged in and out by pressing the position holding device 4 multiple times, so the end connected to the base 10 needs to have a certain strength and the other end needs to have a certain elasticity.
进一步地，接触部43形状为L形，L形的一端与按压部42连接，另一端在接近插接臂20的方向设置。如图7和图9所示，L形拐弯的位置设置加强肋45，加强肋45所在平面垂直L形的平面。加强肋45的设置能够保证接触部43的强度，保证使用寿命。Furthermore, the contact portion 43 is L-shaped, one end of the L-shaped portion is connected to the pressing portion 42, and the other end is disposed in a direction close to the plug arm 20. As shown in FIGS. 7 and 9, a reinforcing rib 45 is disposed at the position where the L-shaped portion is bent, and the plane where the reinforcing rib 45 is located is perpendicular to the plane of the L-shaped portion. The provision of the reinforcing rib 45 can ensure the strength of the contact portion 43 and ensure the service life.
在一实施方式中，卡接弹片60包括相互连接的卡接部63和弹舌62，具体的，卡接部63与卡接槽52卡接，卡接部63一端与插头1或插座2连接，另一端与弹舌62连接，在卡接部的一侧设置容纳位置保持装置4的固定槽61。按压按压部42后，带动接触部43推动弹舌62，使卡接弹片60从卡接槽52中脱离。In one embodiment, the snap-on spring piece 60 includes a snap-on portion 63 and an elastic tongue 62 connected to each other. Specifically, the snap-on portion 63 is snap-on with the snap-on slot 52. One end of the snap-on portion 63 is connected to the plug 1 or the socket 2, and the other end is connected to the elastic tongue 62. A fixing groove 61 for accommodating the position holding device 4 is provided on one side of the snap-on portion. After pressing the pressing portion 42, the contact portion 43 is driven to push the elastic tongue 62, so that the snap-on spring piece 60 is disengaged from the snap-on slot 52.
具体的，在位置保持装置4的作用下，止压块22与弹舌62抵接。通过按压部42按压弹舌62，按压力使卡接弹片60整体受到向下的压力，使卡接部63与卡接槽52脱离，实现插头1和插座2解锁。Specifically, under the action of the position holding device 4, the pressure stop block 22 abuts against the spring tongue 62. The spring tongue 62 is pressed by the pressing portion 42, and the pressing force causes the entire clamping spring sheet 60 to be subjected to downward pressure, so that the clamping portion 63 is disengaged from the clamping groove 52, thereby unlocking the plug 1 and the socket 2.
在一实施方式中，如图9所示，按压部42上表面设置至少一个防滑凸起44，防滑凸起44的延伸方向垂直于***方向延伸设置。In one embodiment, as shown in FIG. 9 , at least one anti-slip protrusion 44 is disposed on the upper surface of the pressing portion 42 , and the extension direction of the anti-slip protrusion 44 is perpendicular to the insertion direction.
防滑凸起44的设置能够保证力作用在按压部42的时候保证按压的有效性。The provision of the anti-slip protrusion 44 can ensure the effectiveness of pressing when force acts on the pressing portion 42 .
在一实施方式中，位置保持装置4还包括固定部30，固定部30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, the position holding 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.
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。At least one reinforcing rib 35 is disposed on the outer surface of the fixing portion 30 , and the reinforcing rib 35 extends in a direction 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，又可以在推动位置保持装置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 ribs 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 position holding device 4 to facilitate operation.
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，保持位置卡接弹片60推入到卡接槽52内，插头1或插座2与位置保持装置4通过凹槽32与凸起72卡接配合，此时的位置保持装置4处于保持位置。In one embodiment, the guide groove 31 includes two side surfaces arranged opposite to each other and a bottom surface connected to the side surfaces, and at least one groove 32 is provided on the bottom surface. A guide rib 70 cooperating with the guide groove 31 is provided on the plug 1 or the socket 2, and a protrusion 72 is provided on the guide rib 70. The position holding spring piece 60 is pushed into the engaging groove 52, and the plug 1 or the socket 2 is engaged with the position holding device 4 through the groove 32 and the protrusion 72. At this time, the position holding device 4 is in the holding position.
如图4-图7所示，引导槽31和引导肋70配合方便位置保持装置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 Figures 4 to 7, the guide groove 31 and the guide rib 70 cooperate to facilitate the plugging of the position holding 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6和图14可知，引导肋70上设置有圆弧形凸起72，当位置保持装置4被推至保持位置时，通过凸起72和凹槽32的配合，实现位置保持装置4在最终位置上的保持。As shown in FIG. 6 and FIG. 14 , an arc-shaped protrusion 72 is provided on the guide rib 70 . When the position holding device 4 is pushed to the holding position, the position holding device 4 is held in the final position through the cooperation between the protrusion 72 and the groove 32 .
在一实施方式中，如图9所示，底面在接近横梁21的端部设置有引导斜面33。In one embodiment, as shown in FIG. 9 , 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，如图9所示，底面在远离横梁21的端部设置有台阶34。In one embodiment, as shown in FIG. 9 , a step 34 is provided on the bottom surface at the end away from the crossbeam 21 .
当位置保持装置4与插座2预安装时，位置保持装置4处于预装位置，引导斜面33起到引导作用与凸起72配合，继续推动位置保持装置4，凸起72和凹槽32的配合，位置保持装置4处于保持位置。When the position holding device 4 is pre-installed with the socket 2, the position holding device 4 is in the pre-installed position, and the guiding slope 33 plays a guiding role and cooperates with the protrusion 72 to continue pushing the position holding device 4. The protrusion 72 and the groove 32 cooperate, and the position holding device 4 is in the holding position.
当需要解锁时，反向推动位置保持装置4，位置保持装置4借用凹槽32的圆滑引导作用挤压凸起72，使位置保持装置4回到预装位置。When unlocking is required, the position holding device 4 is pushed in the reverse direction, and the position holding device 4 uses the smooth guiding effect of the groove 32 to squeeze the protrusion 72, so that the position holding device 4 returns to the pre-installed position.
位置保持装置4的端部设置有台阶34，在解锁反向推动位置保持装置4时，与引导肋70后面的台阶34相互配合，实现位置保持装置4的防退，避免脱出。A step 34 is provided at the end of the position holding device 4 , and when the position holding device 4 is unlocked and pushed in the reverse direction, it cooperates with the step 34 behind the guide rib 70 to prevent the position holding device 4 from retreating and falling out.
如图13所示，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。As shown in FIG. 13 , at least one elongated hole 73 is formed through each of the guide ribs 70 , and the elongated hole 73 is arranged along the extending direction of the guide rib 70 .
如图13所示，当推动位置保持装置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，使位置保持装置4推动到保持位置，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，推动位置保持装置4时，省力的同时，减小位置保持装置4和引导肋70之间的摩擦，提高使用寿命。As shown in FIG13 , when the position holding device 4 is pushed, the projection 72 together with the guide rib 70 deforms downwards through the squeezing action of the guide slope 33, so that the position holding device 4 is pushed to the holding position, the squeezing force of the projection 72 disappears, and the guide rib 70 returns to its original state. The arrangement of the long hole 73 can ensure that when the position holding device 4 is pushed during the unlocking and locking process, the friction between the position holding device 4 and the guide rib 70 is reduced while saving effort, thereby increasing the service life.
