该连接滑块3、连接头4、导电弹簧5和母插座200均为电导体。The connecting slider 3, the connecting head 4, the conductive spring 5 and the female socket 200 are all electrical conductors.
下面介绍如何使用该单头连接装置。The following describes how to use the single-head connection device.
如图9至图11所示，使用者将连接线缆300与连接滑块3尾部的线缆套管31相连接，然后，直接将公插头100的连接头4对准母插座200的连接座筒203，并用力下压公插头100，卡接斜面204滑过锁止突出251，在压力弹簧6的作用下，整个连接头4具有向右运动的趋势，直到锁止突出251卡入到母插环槽202中，整个连接头4得到连接固定，此时压力弹簧6紧压连接滑块3，连接滑块3此时处于锁止位置上。此时，密封圈7和导电弹簧5与连接座筒203的内壁紧密接触，连接头4与母插座200形成可靠的电连接。即使公插头100由于汽车电池的震动而发生细微的转动或移位时，导电弹簧5发生形变后也能保持与连接座筒203内壁的紧密接触，避免电连接失效。As shown in Figures 9 to 11, the user connects the connecting cable 300 to the cable sleeve 31 at the end of the connecting slider 3, and then directly aligns the connecting head 4 of the male plug 100 with the connecting seat of the female socket 200 barrel 203, and press down on the male plug 100, the locking slope 204 slides over the locking protrusion 251, and under the action of the pressure spring 6, the entire connector 4 has a tendency to move to the right until the locking protrusion 251 snaps into the female In the insert ring groove 202, the entire connecting head 4 is connected and fixed. At this time, the pressure spring 6 presses the connecting slider 3 tightly, and the connecting slider 3 is in the locking position at this moment. At this time, the sealing ring 7 and the conductive spring 5 are in close contact with the inner wall of the connecting socket 203 , and the connecting head 4 and the female socket 200 form a reliable electrical connection. Even when the male plug 100 slightly rotates or shifts due to the vibration of the car battery, the conductive spring 5 can still keep in close contact with the inner wall of the connecting socket 203 after being deformed, so as to avoid electrical connection failure.
当公插头100与母插座200相连接时，公插头100可绕母插座200在一微小的范围内转动，比如1～2度左右。When the male plug 100 is connected to the female socket 200, the male plug 100 can rotate around the female socket 200 within a small range, such as about 1-2 degrees.
如图12和图13所示，当使用者需要分离公插头100时，只要手动滑动壳体2，使得锁止突出251从母插环槽202中脱出，此时压力弹簧6被压缩，连接滑块3此时处于释放位置上。这样，使用者就可以轻松将连接头4从母插座200的连接座筒203中脱出，操作简单方便。As shown in Figures 12 and 13, when the user needs to separate the male plug 100, the user only needs to manually slide the housing 2, so that the locking protrusion 251 escapes from the female ring groove 202, at this time the pressure spring 6 is compressed, and the connecting slide Block 3 is now in the release position. In this way, the user can easily disengage the connecting head 4 from the connecting socket 203 of the female socket 200, and the operation is simple and convenient.
其中，活动槽口25可以只在远离第一弹簧限位柱24的一端设置锁止突出251，母插环槽202也可以只设置在一侧。活动槽口25内的连接滑块3被压力弹簧6挤压后，带动母插环槽202的右侧卡入右侧的锁止突出251。Wherein, the movable notch 25 can only be provided with the locking protrusion 251 at the end away from the first spring limiting post 24 , and the female insert ring groove 202 can also be provided only at one side. After the connecting slide block 3 in the movable notch 25 is squeezed by the pressure spring 6, the right side of the female ring groove 202 is driven to snap into the locking protrusion 251 on the right side.
其中，滑块圆孔33可以设置为非贯穿结构，只要可被连接头4插接并与连接头4电连接即可。Wherein, the circular hole 33 of the slider can be set as a non-penetrating structure, as long as it can be inserted into the connector 4 and electrically connected with the connector 4 .
在一个实施例中，连接电池模组的插头件包括公插头100。In one embodiment, the plug member connected to the battery module includes a male plug 100 .
在一个实施例中，连接电池模组的连接装置包括公插头100、导电插片及电连接两者的连接线缆，如图9所示。In one embodiment, the connecting device for connecting the battery module includes a male plug 100 , a conductive insert and a connecting cable for electrically connecting the two, as shown in FIG. 9 .
在一个实施例中，连接电池模组的连接装置包括两个公插头100及电连接两者的连接线缆。In one embodiment, the connecting device for connecting the battery module includes two male plugs 100 and a connecting cable for electrically connecting the two.
