First spherical surface flange 53 is set to charging terminal 30 by the location swap of the first spherical surface flange 53 and the first spherical groove 32
On, the first spherical groove 32 is set on installing frame 50, but this mode, the requirement to 50 wall thickness of installing frame can be improved.
It should be noted that can also be installed on shell 20 with only one charging terminal 30 by installing frame 50 in other embodiments.
Please continue to refer to Fig. 4, the first through slot 33, the first through slot 33 are also provided on two opposite outer walls of charging terminal 30
Thickness direction along charging terminal 30 is arranged, and the end face of charging terminal 30, the other end and first are run through in one end of the first through slot 33
The notch of spherical groove 32 is connected to.When charging terminal 30 is placed on installing frame 50, it is logical that the first spherical surface flange 53 passes through first
Slot 33 enters in the first spherical groove 32.First through slot 33 preferably but is not limited to cylinder through slot, the axis of the first through slot 33 with
The axis of first spherical groove 32 is preferred but is not limited to conllinear, the radius of the radius of the first through slot 33 and the first spherical groove 32
It is preferred that but be not limited to it is identical, in order to process.It should be noted that the shape and size of the first through slot 33 are not limited to
Situation is stated, the first spherical surface flange 53 can allow for be penetrated in the first through slot 33 into the first spherical groove 32, such as the
One through slot 33 also may include multiple vertical wall surfaces in angle setting.First through slot, 33 one side can prevent the first spherical surface convex
Edge 53 and the first spherical groove 32 are detached from, and are improved the stability installed between charging terminal 30 and installing frame 50, are on the other hand improved
Charging terminal 30 stretches to the size in installing frame 50, stretches out installing frame 50 and charging conducive to the charging face 31 of charging terminal 30
Plate contact, another further aspect can be improved the amplitude of up and down motion of the charging terminal 30 relative to installing frame 50.
In order to avoid in 30 swing process of charging terminal or when elastic component 40 is worn, two charging terminals 30 contact with each other
It causes the situation of short circuit to occur, the positioned at 53 two sides of the first spherical surface flange is also provided in two opposed inner walls of installing frame 50
One limiting section is provided with the second limiting section positioned at 32 two sides of the first spherical groove on two opposite outer walls of charging terminal 30,
First limiting section and the second limiting section are matched to limit amplitude of fluctuation of the charging terminal 30 to 53 two sides of the first spherical surface flange.For
Make more compact structure, the first limiting section is defining flange 54, the second limiting section be can accommodate defining flange 54 and with limit
The limiting groove 34 that position flange 54 abuts.In order to avoid the scratch between defining flange 54 and limiting groove 34, optionally, limit convex
Edge 54 is limit spherical surface flange, and limiting groove 34 is limit spherical groove.Limit spherical groove is preferred but is not limited in four points
One of it is spherical.It is convex to set limit spherical groove and limit spherical surface to can according to need the amplitude of fluctuation of the charging terminal 30 of restriction
The radius of edge.For example, limit spherical groove can be enabled identical as the radius of the first spherical groove 32, the radius of spherical surface flange is limited
Less than the radius of the first spherical surface flange 53.
Please continue to refer to Fig. 4, also it is provided on two opposite outer walls of charging terminal 30 positioned at 32 liang of the first spherical groove
Second through slot 35 of side, the second through slot 35 are arranged along the thickness direction of charging terminal 30, and one end of the second through slot 35 is through charging
The end face of terminal 30, the other end are connected to the notch of limiting groove 34.When charging terminal 30 is placed on installing frame 50, limit
Flange 54 passes through the second through slot 35 and enters in limiting groove 34.Second through slot 35 is preferred but is not limited to cylinder through slot, and second is logical
The axis of the axis of slot 35 and limiting groove 34 preferably but be not limited to it is conllinear, the radius of the second through slot 35 and limiting groove 34
Radius preferably but be not limited to it is identical, and in order to processing.It should be noted that the shape and size of the second through slot 35 not office
It is limited to above situation, can allow for defining flange 54 to penetrate in the second through slot 35 into limiting groove 34, such as second
Through slot 35 also may include multiple vertical wall surfaces in angle setting.
It is to be understood that it is dynamic due to needing that charging terminal 30 is allowed to swing sideward, so the slot bottom position of limiting groove 34
Setting should be different from the slot bottom position of the first spherical groove 32, for example, for the charging terminal 30 being located on upper casing 21, limit
The slot bottom position of position groove 34 is higher than the slot bottom position of the first spherical groove 32, for the charging terminal 30 on lower casing 22
Speech, the slot bottom position of limiting groove 34 are lower than the slot bottom position of the first spherical groove 32.It can be by enabling the height of the second through slot 35
Degree is greater than the height of the first through slot 33 to adjust between the slot bottom position of limiting groove 34 and the slot bottom position of the first spherical groove 32
Positional relationship.
It should be noted that in other embodiments can also by the location swap of limiting groove 34 and defining flange 54,
Defining flange 54 is set on the outer wall of charging terminal 30, limiting groove 34 is set on the inner wall of installing frame 50.
It should be noted that the first spherical groove 32 mainly risen with the first spherical surface flange 53 is flexibly connected charging terminal 30 and
The effect of installing frame 50, and the defining flange 54 of two sides and limiting groove 34 are mainly the scope of activities for limiting charging terminal 30,
Two 30 contact short circuits of charging terminal up and down are prevented, can also be changed the first limiting section and the second limiting section in other embodiments
Be set as other structures, such as limited block etc., limited block can with but be not limited to cylindrical.
Below in conjunction with Fig. 3 to Fig. 8, assembling mode and the use of the charging unit of present embodiment offer are briefly introduced
Method:
As shown in Figures 3 to 5, charging terminal 30 is put into installing frame 50, the first spherical surface flange on installing frame 50
53, which pass through the first through slot 33, reaches in the first spherical groove 32, and defining flange 54 passes through the second through slot 35 and reaches limiting groove 34
In, then installing frame 50 is installed to shell 20, while elastic component 40 is connected between charging terminal 30 and shell 20.
As shown in fig. 6, charging terminal 30 is substantially in level when not having charging panel to be inserted between two charging terminals 30
State；As shown in Figure 7 and Figure 8, when there is charging panel to be inserted between two charging terminals 30, charging terminal 30 can pass through
The cooperation of one spherical surface flange 53 and the first spherical groove 32 moves up and down relative to installing frame 50 and/or all around swings, with
The automatic insertion angle etc. for adapting to charging panel, guarantees the good contact of charging terminal 30 and charging panel.
During charging terminal 30 is swung and after charging panel extraction, due to defining flange 54 and limiting groove
34 limit the amplitude of fluctuation of charging panel, and two be oppositely arranged charging terminal 30 will not touch short circuit, highly-safe.
