The uncapped state for the opening of opening for covering storage tank 111 closed lid state and be used to open storage tank 111.
Specifically in the illustrated embodiment, protection cap 130 and 110 movable connection of pedestal.Exist to reduce connector 100
Volume shared by uncapped state, protection cap 130 are contained under uncapped state in the storage tank 111 of pedestal 110.
Further, while leakproofness in order to improve protection cap 130, and the body of connector 100 is further decreased
Product, protection cap 130 are substantially concordant with the outer surface of pedestal 110 in the case where closing lid state.
Specifically in the illustrated embodiment, protection cap 130 includes top plate 132, the first side plate 133 and the second side plate 134, the
Side plate 133 and the setting of 134 relative spacing of the second side plate, and fixed company vertical with the opposite sides of the top plate 132 respectively
It connects.Wherein, the length of the first side plate 133 be more than the second side plate 134 length, the first side plate 133 in the case where closing lid state with pedestal
110 side is concordant, and either flush of the top plate 132 in the case where closing lid state with pedestal 110, the second side plate 134 is parallel to pedestal 110
Storage tank 111 side wall setting.
Further, protection cap 130 is equipped with through-hole 135, for example, in the illustrated embodiment, through-hole 135 is set to protection cap
On 130 top plate 132.The through-hole 135 misplaces in the case where protection cap 130 is in and closes lid state with electrical connection section 121, is specifically illustrating
Embodiment in, on second direction Y, through-hole 135 and electrical connection section 121 misplace, after being inserted into through-hole 135 to avoid external conductor
It is directly in electrical contact with electrical connection section 121, to improve the safety of electrical connection section 121.
Further, which is aligned in the case where protection cap 130 is in uncapped state with electrical connection section 121, outer to facilitate
It can be docked with electrical connection section 121 in the case where protection cap 130 is in uncapped state the plug division of part device.For example, a reality wherein
It applies in example, electrical connection section 121 is plug, and plug passes through through-hole 135 in the case where protection cap 130 is in uncapped state.In other implementations
In example, electrical connection section 121 is jack, and jack is corresponding with through-hole 135 in the case where protection cap 130 is in uncapped state.
The movable connection method of protection cap 130 and pedestal 110 can be the modes such as overturning, sliding.Specifically in the reality of diagram
It applies in example, protection cap 130 is slidably connected with pedestal 110, and protection cap 130 can slide into and close lid state and uncapped state.
The glide direction of protection cap 130 can be designed according to specific requirements, for example, in the illustrated embodiment, protection
Lid 130 is multiple relative to the glide direction of pedestal 110, and multiple glide directions intersect.
