可以理解的是，所述限位连接件703与所述转动臂501的连接方式不限于为支撑抵接，也可以为其他连接方式，只要满足限位连接件703与所述转动臂501的另一端连接之后，所述转动臂501相对所述壳体10固定即可，例如：卡接、螺接等等。
在一些实施例中，所述卡勾502位于所述壳体10外，所述卡勾502与所述外部设备位于所述壳体10外的部分卡接，从而实现对整个外部设备的连接固定。
应当理解的是，为实现对外部设备的固定，不限于利用上述卡勾502的结构，也可以为其他结构，例如：如图8所示，所述卡勾替换为固定件504，所述固定件504包括第一固定板5041、连接板5042和第二固定板5043，所述第一固定板5041的一端连接所述连接板5042的一端，所述第二固定板5043的一端连接所述连接板5042的另一端，所述固定件504呈U型，所述第一固定板5041和第二固定板5043间隔形成固定槽504a，所述固定槽504a可用于卡接于所述外部设备和所述连接头20，从而实现对外部设备的连接固定。
在一些实施例中，如图7、图9以及图10所示，所述转动臂501位于所述收容腔10a内，并且所述转动臂501的一端从所述通孔103伸出，所述转动臂501可相对于所述通孔103摆动，所述转动臂501的另一端暴露于所述第二开口102处，用户可直接在所述第二开口102处按压所述转动臂501的另一端，以使所述转动臂501转动，即可实现设于所述转动臂501一端的卡勾502与所述外部设备断开连接，所述外部设备可自由与所述连接头20断开连接。
在一些实施例中，所述转动臂501的第一表面的另一端设置有固定槽5012，所述固定槽5012用于收容且固定所述弹性件503的一端。
在一些实施例中，所述转动臂501的第一表面的另一端设置有卡槽(未标示)，所述卡槽用于供所述限位连接件703卡接，从而实现限制 所述转动臂501的转动，所述转动臂501相对于所述壳体10固定。
在一些实施例中，所述转动臂501的第二表面的另一端朝所述第二开口102延伸有固定按钮5011，所述固定按钮5011可相对于所述第二开口102移动，通过按压所述固定按钮5011，从而带动所述转动臂501转动，即可实现设于所述转动臂501一端的卡勾502与所述外部设备断开连接，所述外部设备可自由与所述连接头20断开连接。需要说明的是：第二表面和第一表面相对设置，第二表面指的是所述转动臂501远离所述连接头20的一侧的表面。
在另一些实施例中，第一固定组件50和第二固定组件70不局限于如图1-10所示的结构，还可以采用其他的方式，如图11所示，所述第一固定组件50包括设置在连接头上的螺纹结构或卡接结构，所述螺纹结构与外部设备配合以使所述连接器与所述外部设备处于螺接或卡接的一次固定状态。第二固定组件70包括连接臂701和固定头702，所述固定头702设置于所述连接臂701的一端，所述连接臂701的另一端连接于所述开关40。
在连接器的连接头与外部设备完成卡接或螺接后，当所述开关40控制所述第一信号连接点和所述第二信号连接点导通时，所述开关40带动连接臂701往靠近所述连接头20的方向运动且所述固定头702与外部设备固定连接，以对处于一次固定状态(螺接或卡接状态)的外部设备进行二次固定，使得外部设备与所述连接器不可拆卸。当所述开关40控制所述第一信号连接点和所述第二信号连接点关闭时，所述开关40带动连接臂701往远离所述连接头20的方向运动且所述固定头702与外部设备分离，以解除所述外部设备的二次固定状态，此时，所述外部设备与所述连接头20之间可拆卸。可以理解的是，所述连接臂701与所述开关40之间的固定方式可以焊接、螺接等等。
对于上述防护组件60，如图2所示，所述防护组件60包括防护盖601和弹性连接件602，所述弹性连接件602的一端连接于所述壳体10，所述弹性连接件602的另一端连接于所述防护盖601，所述防护盖601盖设于所述连接头20。所述连接器在处于未使用状态时，利用所述防护盖601盖设于所述连接头20，减少所述连接头20内的通讯信号引脚201以及电信号引脚202暴露于空气中并与空气中的水分接触。
在本申请实施例中，通过设置有壳体10、电路板30、连接头20和开关40，其中，所述壳体10设置有收容腔10a以及连通所述收容腔10a的第一开口101，所述电路板30设置于所述收容腔10a内，所述电路板30设置有第一信号连接点，所述连接头20设置于所述壳体10，所述连 接头20设置有用于与外部设备连接的第二信号连接点；此外，所述开关40设置于所述第一开口101，所述开关40分别与所述电路板30的第一信号连接点和所述连接头20的第二信号连接点连接，所述开关40用于控制所述电路板30的第一信号连接点和所述连接头20的第二信号连接点之间的导通和关闭。在连接器连接大负载的情况下，用户在拔出连接器之前，只需利用开关40断开所述电路板30与所述连接头20之间的信号连接，即实现断开连接器和大负载之间的连接，避免连接器拔出时出现瞬间打火以及造成短路的危险，减少安全事故发生。
通过连接器上设置用于与外部设备连接稳固的第一固定组件50，以及所述开关40上设置第二固定组件70，当所述开关40控制所述第一信号连接点和所述第二信号连接点导通时，所述第二固定组件70与处于一次固定状态中的所述第一固定组件50配合，从而使得外部设备与连接器的连接处于二次稳固状态，保证在连接器与外部设备通电状态下，连接器与外部设备之间处于稳固连接及不可拆卸状态。在所述开关40控制所述第一信号连接点和所述第二信号连接点关闭时，所述第二固定组件70与处于一次固定状态中的所述第一固定组件50分离，解除对第一固定组件状态的固定，进一步保证连接器与外部设备在拆卸前两者之间的信号(尤其是电信号)处于关闭状态，避免打火或短路的危险。
当需要将该连接器与外部设备(大负载设备或电源)连接时，先将连接器的连接头20与外部设备连接，再通过第一固定组件50对外部设备进行一次稳固固定，然后将开关40开启，实现大负载和连接器间的信号连通(电连接等)，同时第一固定组件50的状态被第二固定组件70所固定，连接器与外部设备稳固连接且不可拆卸。当需要将连接器与外部设备拆卸断开时，必须先将开关40关闭，断开大负载和连接器间的信号连接，同时解除对第一固定组件50状态的固定，如此才允许后续连接器与外部设备之间的拆卸。
本申请还提供了一种电子设备的实施例，电子设备包括如上所述的连接器01，连接器01的功能和结构可参阅上述实施例，此处不再一一赘述。
以上所述仅为本申请的实施例，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
