Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector used for connecting a charging pile to a reactive power compensation device. Background Art

[0002] The power electronic converter in the charging pile will generate harmonics when converting electric energy. These harmonic currents will be injected into the power grid, causing the grid voltage waveform to be distorted. Some types of reactive power compensation devices, such as static VAR generators (SVGs), can not only compensate for reactive power, but also suppress harmonics to a certain extent.

[0003] In the parallel connection between the charging pile and the reactive compensation device, the output end of the reactive compensation device is connected to the grid busbar where the AC input side of the charging pile is located, rather than being inserted into each other; specifically, the AC power line drawn from the grid will first be connected to a wiring point (such as the busbar in the distribution cabinet), which simultaneously connects the AC input of the charging pile and the input of the reactive compensation device. The line at the output end of the reactive compensation device (usually a capacitor bank or the output terminal of the reactive compensation device) is also connected to this common wiring point; in this way, the reactive compensation device and the charging pile form a parallel relationship on the grid side.

[0004] During the connection process between the charging pile and the reactive compensation device, the three-phase lines of the charging pile and the three-phase lines of the reactive compensation device need to be connected to the busbar board respectively. Before the connection, the worker needs to open the protective cover of the busbar board socket, and then the busbar board can be connected to the two or three-phase lines. The operation is relatively cumbersome for the worker. Utility Model Content

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] See also Figure 1-5 The utility model provides a plug-in device for connecting a charging pile to a reactive compensation device, comprising a busbar plate 1 and two line bars 2. The busbar plate 1 is connected to the busbar and has a plurality of interfaces 11 on opposite sides thereof, wherein one line bar 2 clamps and fixes the input line of the charging pile, and the other line bar 2 clamps and fixes the input line of the reactive compensation device; a protective mechanism is respectively arranged between the two line bars 2 and the busbar plate 1, each protective mechanism comprising a protective cover 12 and a propulsion assembly, the protective cover 12 is slidably connected to the busbar plate 1, and the protective cover 12 has a covering position covering the corresponding interface 11 in the sliding stroke relative to the busbar plate 1; the propulsion assembly is assembled to The process of the corresponding line row 2 docking close to the busbar connecting plate 1 drives the corresponding protective cover 12 to leave the covering position. Specifically, the propulsion assembly includes a first guide rod 13, a second guide rod 14, a hinged rod 31 and an arc plate 21. The first guide rod 13 is fixedly connected to the busbar connecting plate 1, and a sliding sleeve 3 is slidably connected to the first guide rod 13; the second guide rod 14 is fixedly connected to the busbar connecting plate 1, and the second guide rod 14 is slidably connected to the corresponding protective cover 12; one end of the hinged rod 3 is hinged to the sliding sleeve 3, and the other end is hinged to the protective cover 12; the arc plate 21 is fixedly connected to the line row 2, and a through hole 211 that slidably cooperates with the first guide rod 13 is opened on the arc plate 21.

[0023] The worker first connects the through hole 211 of the arc plate 21 to the first guide rod 13, so that the line bus 2 can slide relative to the first guide rod 13. During the sliding of the line bus 2 relative to the first guide rod 13, the arc plate 21 on the line bus 2 can abut the sliding sleeve 3 of the first guide rod 13, so that the sliding sleeve 3 slides relative to the first guide rod 13. The sliding of the sliding sleeve 3 pushes the protective cover 12 to slide relative to the second guide rod 14 through the hinge rod 31. The protective cover 12 gradually separates from the covering position during the movement. Although the protective cover 12 will continue to move for a distance, the input line on the line bus 2 can be inserted into the interface 11 on the busbar board 1. The two line buses 2 perform the above-mentioned operation process respectively, so that the charging pile can be connected to the reactive power compensation device.

[0024] Compared with the prior art, the utility model provides a plug connector for connecting a charging pile to a reactive compensation device. When a worker connects the input line of the charging pile with the input line of the reactive compensation device through a busbar connecting plate 1, the worker first needs to slowly move the wire row 2 with the input line of the charging pile close to the busbar connecting plate 1. During this process, the wire row 2 drives the protective cover 12 to open automatically through the pushing component, so that the interface 11 on the busbar connecting plate 1 is exposed. In this way, the worker does not need to open the protective cover 12 separately, which facilitates the worker's work.

[0025] Among them, there are two first guide rods 13 and two second guide rods 14. The two first guide rods 13 can make the line row 2 move more smoothly when approaching the busbar connection plate 1, and the two second guide rods 14 can make the protective cover 12 move more smoothly when sliding away from the covering position.

[0026] Among them, the protection mechanism also includes a locking mechanism, which includes a wedge block 4, an abutment portion 22 and an elastic member 5. The wedge block 4 is slidably connected to the busbar plate 1, and the wedge block 4 has an avoidance position and a relative blocking position in the sliding stroke relative to the busbar plate 1; the abutment portion 22 is fixedly connected to the line row 2, and a rectangular groove 221 is provided on the abutment portion 22; the process of the elastic member 5 restoring the deformation drives the wedge block 4 to slide to the blocking position. Specifically, the elastic member 5 includes a spring, one end of the spring is connected to the busbar plate 1, and the other end of the spring is connected to the wedge block 4. A connecting rod 41 is fixedly connected to the wedge block, and the other end of the connecting rod 41 extends to the outside of the busbar plate 1, and the other end of the connecting rod 41 is fixedly connected to a pull button 411.

[0027] After the worker opens the protective cover 12 by pushing the assembly, the worker continues to manipulate the line row 2 to make the line row 2 approach the busbar plate 1, and the abutment portion 22 on the line row 2 will enter the insertion hole opened on the busbar plate 1. During the movement of the abutment portion 22 entering the insertion hole of the busbar plate 1, the abutment portion 22 will first contact and abut the wedge block 4. After the wedge block 4 is abutted, it will switch from the blocking position to the avoidance position. When the abutment portion 22 goes deeper into the busbar plate 1, the rectangular groove 221 of the abutment portion 22 is completely The method continues to abut the wedge block 4, and the wedge block 4 is subjected to the elastic force of the spring, thereby switching the wedge block 4 from the avoidance position to the blocking position, thereby locking and fixing the line bar 2 on the busbar connecting plate 1; when the worker moves the line bar 2 to connect with the busbar connecting plate 1, the protective cover 12 is automatically opened by the pushing assembly, and then continues to move so that the locking assembly automatically locks the line bar 2, which facilitates the worker's work and improves the practicability of the device; the cooperation between the pull rod and the pull button 411 facilitates the worker to unlock the line bar 2.

[0028] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
