As shown in Figure 1 to Figure 3, aforementioned guiding, which catches line mechanism 3, can include the guide pad being arranged on insulator foot 1,
To capture external first grid line 10 and external second grid line 20 by guide pad, and to respective external grid line with accordingly leading
Docking between electric part is oriented to.Wherein, trolley pole drives trolley head 100 to move, and moves closer to the guide pad on trolley head 100
External electrical cable after guide pad is contacted with external electrical cable, that is, realizes the capture to external grid line；Then trolley pole continues
Trolley head 100 is driven to move, guide pad is made to continue to keep contacting with external electrical cable, and the importing of external electrical cable is led accordingly
Electric part makes grid line be docked with corresponding conduct piece.
Further, as shown in Figure 1 to Figure 3, above-mentioned guide pad can include being arranged on the first conduct piece 41 and second
The first guide pad 31 between conduct piece 42.First guide pad 31 can also be referred to as interior guide pad.First guide pad 31 wraps
Include the first guide surface and the second guide surface being disposed opposite to each other.Both first guide surface and the second guide surface are along far from insulator foot 1
Direction it is relatively close, the two can be in inverted V-shaped.First guide surface is led for capturing external first grid line 10 to first
Electric part 41 docks guiding with external first grid line 10.Second guide surface is for capturing external second grid line 20, and to the
Two conduct pieces 42 dock guiding with external second grid line 20.
Specifically in operation, trolley pole drives trolley head 100 to move, and makes the first guide pad 31 from external first grid line 10
Intermediate with the second grid line 20 is inserted into, until the first guide surface of the first guide pad 31 contacts and the with the first grid line 10
Two guide surfaces are contacted with the second grid line 20, realize the capture to the first grid line 10 and the second grid line 20.Then trolley pole
Continue that the first guide pad 31 is driven to be inserted upwardly between the first grid line 10 and the second grid line 20, if the first conduct piece 41 at this time
It is inconsistent with the angle of corresponding grid line with both the second conduct pieces 42, at this time grid line can to 31 applied force of the first guide pad,
The first guide pad 31 is made to drive insulator foot 1 around 2 rotary oscillation of connector, until the angle of grid line and corresponding conduct piece 4 is protected
It holds consistent；Then trolley pole is adjusted, the first guide pad 31 is oriented to grid line, and grid line is made to be docked with corresponding conduct piece.
Further, as shown in Figure 1 to Figure 3, the first above-mentioned guide pad 31 can be led including spaced first son
To 311 and second sub- guide pad 312 of block.First sub- guide pad 311 has the first aforementioned guide surface.Second sub- guide pad 312
With the second aforementioned guide surface.In this example, due to having between the first sub- 311 and second sub- guide pad 312 of guide pad
Interval so as to increase the distance between the first conduct piece 41 and the second conduct piece 42, can prevent the first conduct piece 41 and the
Electricity is climbed between two conduct pieces 42.Wherein, " electricity is climbed " to refer to be hit by voltage between the first conduct piece 41 and the second conduct piece 42
It wears and short circuit occurs.
Further, as shown in Figure 1 to Figure 3, the first aforementioned guide pad 31 can pass through the first supporting walls 5 and insulation bottom
Seat 1 connects.One end that first guide pad 31 is connected with the first supporting walls 5 can have the first convex eaves structure 310.The first convex eaves
Structure 310 is similar to the eaves in house, has the technique effect of rain cover.So in the rainy day, at the first convex eaves structure 310
Drying can be kept, prevents that short circuit occurs by electric conduction of rainwater between the first conduct piece 41 and the second conduct piece 42.
Further, as shown in Figure 1 to Figure 3, aforementioned guide pad can also include spaced second guide pad 32
With third guide pad 33.Second guide pad 32 is arranged on the side far from the second conduct piece 42 of the first conduct piece 41.Third is led
The side far from the first conduct piece 41 of the second conduct piece 42 is arranged on to block 33.Wherein, the guide surface 321 of the second guide pad 32
It is opened out against with 331 the two of guide surface of third guide pad 33.The guide surface 321 of second guide pad 32 is used to capture outside
First grid line 10, and guiding is docked to the first conduct piece 41 and external first grid line 10.The guiding of third guide pad 33
Guiding is docked to the second conduct piece 42 and the second grid line 20 of outside for capturing external second grid line 20 in face 331.
Specifically in operation, trolley pole drives trolley head 100 to move, and makes the second guide pad 32 from the side of external electrical cable
It is inserted into and third guide pad 33 is inserted into from the opposite side of external electrical cable, at this time external first grid line 10 and the second grid line
20 between the second guide pad 32 and third guide pad 33, until 321 and first grid line of guide surface of the second guide pad 32
10 contacts, the guide surface 331 of third guide pad 33 are contacted with the second grid line 20, are realized to the first grid line 10 and the second power grid
The capture of line 20.Then trolley pole continues that the second guide pad 32 and third guide pad 33 is driven to be inserted into from the both sides of grid line, this
If when both the first conduct piece 41 and the second conduct piece 42 it is inconsistent with the angle of corresponding grid line, grid line can be to leading accordingly
To block applied force, the second guide pad 32 and third guide pad 33 is made to drive insulator foot 1 around 2 rotary oscillation of connector, until electricity
The angle of cable and corresponding conduct piece is consistent；Then trolley pole is adjusted, the second guide pad 32 and third guide pad 33 are distinguished
Corresponding grid line is oriented to, grid line is made to be docked with corresponding conduct piece.
As shown in Figure 1 to Figure 3, the second above-mentioned guide pad 32 can be connect by the second supporting walls 6 with insulator foot 1.
One end that second guide pad 32 is connected with the second supporting walls 6 can have the second convex eaves structure 320.The second convex eaves structure 320
Similar to the eaves in house, there is the technique effect of rain cover.So in the rainy day, it can be protected at the second convex eaves structure 320
Drying is held, is prevented conductive and generation from the back side of insulator foot 1 by rainwater between the first conduct piece 41 and the second conduct piece 42
Short circuit.
Likewise, as shown in Figure 1 to Figure 3, above-mentioned third guide pad 33 can pass through third supporting walls 7 and insulator foot
1 connection.One end that third guide pad 33 is connected with third supporting walls 7 can have the convex eaves structure 330 of third.The convex eaves knot of the third
Structure 330 is similar to the eaves in house, has the technique effect of rain cover.So in the rainy day, energy at the convex eaves structure 330 of third
Enough keep drying, prevent between the first conduct piece 41 and the second conduct piece 42 by rainwater from the back side of insulator foot 1 it is conductive and
Short circuit occurs.
The inverted V-shaped design or outer guide pad i.e. the second guide pad of i.e. the first guide pad 31 of above-mentioned either interior guide pad
The open type design of both 32 and third guide pad 33 cooperation, allows trolley head 100 conveniently and efficiently to capture external electrical
Cable.And when vehicle is more, which can charge in multiple spot simultaneously, without being lined up, when saving charging
Between.Since without being lined up, so as to which the requirement to place is relatively low, the cost of charging station construction can be saved.
What needs to be explained here is that：As shown in figure 3, one end, that is, insulator foot away from conduct piece 4 of above-mentioned insulator foot 1
1 back side can be equipped with reinforcing rib 21, on the one hand can strengthen the intensity of insulator foot 1, on the other hand can also increase electric current
The distance of electricity is climbed from 1 back side of insulator foot, reduces and climbs the risk that short circuit occurs for electricity.
