Optionally, referring to fig. 2 and 3, the housing 10 includes a first portion 12 and a second portion 13, where the first portion 12 is provided with a first cavity (not labeled in the drawing) and the second portion 13 is provided with a second cavity (not labeled in the drawing). Various electronic components such as the switch 20 and the circuit board can be arranged in the first pit cavity or the second pit cavity in advance, and then the first part 12 is connected with the second part 13, wherein the first pit cavity is arranged facing the second pit cavity, and the two pit cavities are mutually communicated to form the accommodating cavity 11, and the assembling method is easier to enable the circuit board to be arranged in the accommodating cavity 11. In addition, the connection mode of the first portion 12 and the second portion 13 may adopt ultrasonic welding, so as to ensure tightness of the housing 10 and improve waterproof effect of the housing 10.

For the plug 30, referring to fig. 1 and 2, the plug 30 is disposed outside the housing 10 and can be plugged into the external socket 2000. The plug 30 extends partially into the accommodating cavity 11 and is electrically connected with the current loop, when the plug 30 is plugged into the external socket 2000 and the switch 20 is closed, the current loop is conducted with the socket 2000, so that the connector 1000 is conducted with the socket 2000.

For the key 40, referring to fig. 2 and 4, the key 40 is disposed in the accommodating cavity 11 of the housing 10, and a portion of the key 40 is exposed out of the housing 10.

The other end of the pushing portion 60 is connected to the end of the key 40 away from the buckle 50, and the movement of the key 40 can drive the pushing portion 60 to move, wherein the pressing of the key 40 can drive the pushing portion 60 to disengage from the switch 20, i.e. the switch 20 is turned off (refer to fig. 1).

Referring to fig. 1 and 4, optionally, since the pushing portion 60 does not include various electronic components, the pushing portion 60 may also be disposed in the second cavity 112, for example, the second sub-cavity 1122 is disposed.

In order to ensure that the pushing portion 60 can press against the switch 20 in the first cavity 111 in the second cavity 112, in some embodiments, referring to fig. 2 and 4, a sealing plate 90 is disposed between the first cavity 111 and the second cavity 112, and the sealing plate 90 is disposed to isolate the first cavity 111 and the second cavity 112. Wherein, the pushing portion 60 is disposed in the second cavity 112 near the sealing plate 90, the switch 20 is disposed in the first cavity 111 near the sealing plate 90, the sealing plate 90 may be made of a flexible material, and when the pushing portion 60 abuts against the sealing plate 90, the sealing plate 90 may abut against the switch 20, so that the switch 20 is closed and turned on; when the key 40 is pressed, the pushing portion 60 is driven to disengage from the sealing plate 90, and the switch 20 is turned off.

With continued reference to fig. 2 and 4, in some embodiments, a guide rail 1123 is disposed in the second cavity 112, and the guide rail 1123 is disposed in the second sub-cavity 1122. The guide rail 1123 is disposed along the direction from the key 40 to the sealing plate 90, and the pushing portion 60 is movably disposed on the guide rail 1123, that is, the key 40 can drive the pushing portion 60 to move along the guide rail 1123, so as to ensure that the pushing portion 60 can precisely press against or separate from the sealing plate 90. Optionally, the second cavity 112 is provided with a limit groove extending from the key 40 towards the sealing plate 90, in which limit groove the pushing part 60 can move, i.e. the limit groove forms the guide rail 1123.

Optionally, referring to fig. 7, the pushing portion 60 has a first surface 61 and a second surface 62 that are disposed opposite to each other, the first surface 61 and the second surface 62 are disposed parallel to the guide rail 1123, and the pushing portion 60 has a through hole 63 penetrating the first surface 61 and the second surface 62. In the direction (first direction X) from the pushing portion 60 to the sealing sheet 90, the through hole 63 has a first inclination angle α with respect to the first surface 61, satisfying 40 ° - α -50 °.

Referring to fig. 8, a push-in member 44 is disposed at an end of the key 40 near the pushing portion 60, and the inclination angle between the push-in member 44 and the first surface 61 may be set to be the same as α, where the push-in member 44 is bent toward the pushing portion 60 and partially inserted into the through hole 63. When the key 40 is pressed, the push-in member 44 is pressed down, and the push-in member 44 extends continuously below the through hole 63, and the pushing portion 60 moves continuously to the left, i.e. continuously toward the direction approaching to the key 40, so that the pushing portion 60 is separated from the switch 20. Thus, the switch 20 can be controlled by the key 40 under the condition that the first cavity 111 and the second cavity 112 are isolated from each other.

In other embodiments, a mounting groove (not shown) is provided at the connection between the first cavity 111 and the second cavity 112, and the sealing piece 90 is partially disposed in the mounting groove.

Referring to fig. 2 and 4, the connector 1000 further includes a first sealing ring 100, where the first sealing ring 100 is sleeved on the plug 30 and seals a connection portion between the plug 30 and the housing 10. Since the plug 30 needs to be partially disposed in the first cavity 111 and partially extend out of the housing 10, in order to ensure the tightness between the plug 30 and the housing 10, in the embodiment of the application, the first sealing ring 100 is used, which fills the gap between the plug 30 and the housing 10, so as to ensure the tightness of the first cavity 111, so as to reduce the external moisture entering the first cavity 111.

In other embodiments, the connector 1000 further includes a cable 110 and a second seal ring 120. Similar to the plug 30, the cable 110 is connected to the housing 10 and partially disposed outside the housing 10, and the cable 110 is electrically connected to the current loop. The second sealing ring 120 is sleeved on the cable 110 and sealed at the connection position between the cable 110 and the housing 10, for example, the first portion 12 and the second portion 13 are welded by ultrasonic, the cable 110 is disposed between the first portion 12 and the second portion 13, and the second sealing ring 120 can fill a gap between the cable 110 and the housing 10 to ensure the tightness of the first cavity 111. In addition, since the outer skin of the cable 110 has a certain elasticity, after the first portion 12 and the second portion 13 are ultrasonically welded, the outer skin of the cable itself can also have a certain buffer sealing effect, so that the sealing performance of the first cavity 111 is further ensured.

In some embodiments, the current circuit includes a low-voltage system circuit (not shown) connected to the switch 20 and a high-voltage system circuit (not shown) connected to the plug 30, wherein the low-voltage system circuit is configured to control on/off of the high-voltage system circuit (i.e., weak current controls strong current). When the switch 20 is closed and turned on, the low voltage system loop is activated and the low voltage system loop controls the high voltage system loop to be turned on, i.e. the high voltage path between the plug 30 and the socket 2000 is turned on. When the switch 20 is turned off, i.e. the low voltage system loop is turned off, a reaction time of at least 25ms is required to turn off the high voltage system loop to perform the breaking buffer function, and at this time, the plug 30 is pulled out of the socket 2000, so that the arcing and wire burning phenomenon will not occur, and the safety of the separation of the plug 30 from the socket 2000 is improved.

The connector 1000 in the present application works as follows:

referring to fig. 1, when the plug 30 is required to be plugged into the socket 2000, the key 40 is pressed, the buckle 50 is lifted up under the action of the pivot 80, and the push-in member 44 is pushed down by the lowering of the key 40, so that the pushing portion 60 moves away from the sealing plate 90 to turn off the switch 20. Thus, the plug 30 can be conveniently plugged into the socket 2000 at a preset position.

Referring to fig. 9, when the plug 30 and the socket 2000 are plugged, the key 40 is released, and the key 40 is lifted up and exposed out of the housing 10 by the elastic member 70. At this time, the buckle 50 is pressed down and is clamped with the socket 2000, so that the plug 30 and the socket 2000 are ensured to be inserted and connected stably. In addition, during the process that the elastic member 70 pushes the key 40 to rise, the push-in member 44 rises to drive the pushing portion 60 to move towards the sealing sheet 90, so as to press the sealing sheet 90 to close the switch 20, and at this time, the low-voltage system is started. After the low-voltage system loop is started, the high-voltage system loop between the plug 30 and the socket 2000 is controlled to be started, and the high-voltage power between the socket 2000 and the plug 30 can be normally conducted for operation.

Referring to fig. 1, when the plug 30 is required to be separated from the socket 2000, the push button 40 is pressed, the push member 44 is pressed down to drive the push portion 60 to move away from the sealing plate 90, so as to disengage from the switch 20, and at this time, the switch 20 is opened, and the low voltage system circuit is closed. After the low-voltage system is closed, the reaction time of at least 25ms is needed to disconnect the high-voltage system loop, the time is prolonged by operating the key 40, the sectional reaction time of the high-voltage system loop can be fully satisfied in the operation time, the sectional buffer function is exerted, and the phenomenon of arc discharge and line burning can not occur when the plug 30 is pulled out of the socket 2000, so that the safety of the plug 30 and the socket 2000 during separation is improved.

To sum up, in the embodiment of the present application, the pushing of the key 40 can simultaneously control the pushing portion 60 and the buckle 50, and pressing the key 40 can drive the buckle 50 to rotate around the rotation pivot 80, so as to be convenient for being clamped with the external socket 2000, thereby ensuring the stability of the plug 30 and the socket 2000 in insertion; and pressing the key 40 can also drive the pushing part 60 to be separated from the switch 20, namely, the current loop connected with the plug 30 is disconnected. When the external socket 2000 is required to be plugged in, the key 40 is pressed, the buckle 50 is lifted, the pushing part 60 is separated from the switch 20, and the current loop is disconnected; when the plug 30 and the socket 2000 are plugged, the key 40 is released, the key 40 is lifted, the buckle 50 is pressed down and clamped with the socket 2000, and the pushing part 60 moves towards the switch 20, so that the switch 20 is closed and conducted, and the current loop is conducted, namely, the normal conduction operation between the socket 2000 and the plug 30 is performed. The linkage of the key 40, the buckle 50 and the pushing part 60 can realize the control of the buckle 50 and the pushing part 60 at the same time, namely, the stable plug-in connection of the plug 30 and the socket 2000 and the current conduction between the plug 30 and the socket 2000 can be realized by one-step operation of the key 40. Convenient operation and simple structure do benefit to the maintenance of later stage.
