Description

Technical Field

[0001] The present invention relates to the technical field of microgrids, and in particular to a connection device applied to a microgrid. Background Art

[0002] Microgrid, also translated as microgrid, refers to a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, loads, monitoring and protection devices, etc. The purpose of the microgrid is to achieve flexible and efficient application of distributed power sources and solve the problem of grid connection of a large number of distributed power sources in various forms. The development and extension of microgrids can fully promote the large-scale access of distributed power sources and renewable energy, realize highly reliable supply of various energy forms to loads, and is an effective way to realize active distribution networks, making the transition from traditional power grids to smart grids.

[0003] When a microgrid is connected to the grid, a connector is required to transmit high-frequency and high-speed signals. The existing patent document with the announcement number CN221009348U discloses a pressure-resistant electrical connector. The top plate is moved by hand and placed on the top of the socket and the plug. Then, the protective plate 2 and the protective plate 1 are rotated by hand, and then the rotating plate 2 and the rotating plate 1 are rotated, and then the protective plate 2 and the rotating plate 1 are made to be close to the surface of the socket and the plug. The movement of the protective plate 1 drives the fixed plate 2 to move, and then drives the cylinder to move, and then drives the connecting rod to move to the back side, and then drives the convex plate to move, and then After that, the convex plate is inserted into the interior of the shell, and at the same time, the card plate is moved outward. After reaching the specified position, the card plate is restored to its original position under the action of the spring, so as to fix the convex plate in the working state, thereby achieving the effect of fixing the protective plate 2 and the protective plate 1 on the surface of the socket and the plug, solving the problems that dust is very easy to enter the interface of the existing electrical connector during use, which easily affects the service life of the electrical connector, the protective plate is not easy to disassemble, which is not convenient for the operator to repair the electrical connector later, and the connecting line interface is very easy to break, thereby affecting the use of the electrical connector.

[0004] Although the above-mentioned pressure-resistant electrical connector can solve the corresponding technical problems, its protective mechanism structure is relatively simple and the model is single. When a smaller electrical connector body is placed in the protective mechanism, the electrical connector body will become loose under the action of external force, and a larger electrical connector body is difficult to place in the protective mechanism, resulting in different electrical connector bodies needing to be equipped with different models of protective mechanisms. The applicability of the protective mechanism is poor. For this reason, a connection device for microgrids is proposed. Summary of the invention

When in the open state, it is convenient to take and put the electrical connector body 100; when in the closed state, the protection operation of the electrical connector body 100 is realized; the clamping member 230 includes a pull rod 231, and the pull rod 231 is movably arranged in the corresponding first hollow column 211, and one end of the pull rod 231 is fixedly connected to a positioning column 232, and the positioning column 232 is away from the pull rod 231. One end of the pull rod 231 penetrates into the inner cavity of the corresponding second hollow column 221, and the other end of the pull rod 231 penetrates into the outer side of the first hollow column 211 and is fixedly connected with a pull block 233 to facilitate pulling the pull rod 231.

When the positioning column 232 is inserted into the inner cavity of the corresponding second hollow column 221, the first protective shell 210 and the second protective shell 220 can be locked, so that the first protective shell 210 and the second protective shell 220 are stably maintained in a closed state, so as to realize the protection operation of the electrical connector body 100;When the positioning column 232 is separated from the inner cavity of the corresponding second hollow column 221, the first protective shell 210 and the second protective shell 220 can be unlocked, so that the first protective shell 210 and the second protective shell 220 can be rotated open to facilitate the removal and placement of the electrical connector body 100; a limiting member is provided between the positioning column 232 and the inner wall surface of the corresponding first hollow column 211; the limiting member includes a limiting groove 235 opened in the inner cavity of the corresponding first hollow column 211, the inner cavity of the limiting groove 235 is slidably connected to the limiting block 236, and the limiting block 236 is fixedly connected to the positioning column 232. When the positioning column 232 moves, it can drive the limiting block 236 to slide in the inner cavity of the limiting groove 235, which plays a limiting role, so that the positioning column 232 can stably slide in the inner cavity of the corresponding first hollow column 211, and can prevent the positioning column 232 from slipping out of the inner cavity of the corresponding first hollow column 211; the surface of the positioning column 232 is provided with an inclined surface 2321 on the side close to the corresponding second hollow column 221, and the force direction can be changed by the inclined surface 2321, so that the corresponding second hollow column 221 rotates with the second protective shell 220 around the rotating shaft and close to the inclined surface 2321 When the first and second protective shells 210 and 220 are closed, the first and second protective shells 210 and 220 can be quickly closed without the need for operating the clamping member 230. The outer surfaces of the first and second protective shells 210 and 220 are integrally formed with a convex ring 240. The two adjacent convex rings 240 contact each other and form a cavity for the wire to pass through. The convex ring 240 can be used to close the socket 1 10 and the connection point between the wire and the plug 120 and the wire play a supporting role, effectively avoiding the phenomenon of the connection point being damaged due to bending during long-term use, which helps to ensure the normal transmission of data.

[0059] The distance adjustment component 300 includes a telescopic member, and the telescopic member is respectively provided between the two first protective shells 210 and the two second protective shells 220; the telescopic member includes a first baffle 310, one side of which is fixedly connected to the corresponding first protective shell 210, and one side of the other first baffle 310 is fixedly connected to the corresponding second protective shell 220. A group of second baffles 320 are provided inside the first baffle 310, one end of which is fixedly connected to the corresponding first protective shell 210, and one end of the other group of second baffles 320 is fixedly connected to the corresponding second protective shell 220.

The two ends of the second spring 432 are respectively fixedly connected to the two ends of the damper 431. When the electrical connector body 100 is placed between two adjacent clamping plates 410, the clamping plate 410 can apply a force to the second spring 432, so that the second spring 432 is deformed. Since the force is mutual, the second spring 432 also gives the clamping plate 410 an identical reaction force, so that the clamping plate 410 gives the electrical connector body 100 a clamping force. The electrical connector body 100 can be fixed thereby; the damper 431 can not only limit the second spring 432 to prevent the second spring 432 from being skewed, thereby helping to extend the service life of the second spring 432, but also cooperate with the second spring 432 to prevent the electrical connector body 100 from shaking. When the electrical connector body 100 or the wire of the electrical connector body 100 is collided or pulled by an external force, the damper 431 and the second spring 432 can be used to convert the impact force generated into elastic potential energy to offset the impact force, thereby preventing the electrical connector from being damaged. The device body 100 swings in the protective component 200; the end of the connecting plate 420 away from the splint 410 is rotatably connected to the guide wheel 440 through a bearing, and two guide wheels 440 are symmetrically arranged. Guide grooves 600 are opened on both sides of the inner cavity of the slide groove 500, and the inner wall surface of the guide groove 600 is slidably connected with the surface of the corresponding guide wheel 440. When the connecting plate 420 rotates with the rotating shaft between the splint 410 and the connecting plate 420 as the axis, it can drive the guide wheel 440 to roll in the inner cavity of the guide groove 600, which can not only improve the flexibility of the connecting plate 420, but also prevent the connecting plate 420 from slipping out of the inner cavity of the slide groove 500.

[0061] Working principle:

[0062] S1. Connecting the electrical connector body 100: plugging the socket 110 and the plug 120 together so that the rubber ring gasket 130 contacts the plug 120, thereby completing the connection operation of the electrical connector body 100;

[0063] S2. Assemble the protective assembly 200: place the wiring terminal of the socket 110 on the clamping plate 410 in one of the first protective shells 210, and place the wiring terminal of the plug 120 on the clamping plate 410 in the other second protective shell 220, so that the wires on the socket 110 and the plug 120 are respectively placed in the corresponding convex rings 240; then rotate the second protective shell 220 toward the direction of the first protective shell 210, and the second protective shell 220 drives the clamping assembly 400, the first baffle 310 and the second baffle 320 in its inner cavity to move synchronously, and the second protective shell 220 drives one of the second hollow columns 221 to gradually approach the corresponding first hollow column 211, and when the second hollow column 221 squeezes the positioning column 232 through the inclined surface 2321, the positioning column 232 is forced to move toward the inner cavity of the corresponding first hollow column 211. The first spring 234 is forced to contract until the first protective shell 210 and the second protective shell 220 are in a closed state, and the second hollow column 221 is clamped into the corresponding first groove 212, and the first hollow column 211 is clamped into the corresponding second groove 222, so that the positioning column 232 loses its constraint. The elastic restoring force of the first spring 234 restores the positioning column 232 to its original state and is clamped into the corresponding second hollow column 221, so that the first protective shell 210 and the second protective shell 220 are stably maintained in the closed state, and the assembly operation of the protective assembly 200 is completed, so as to improve the protective effect of the electrical connector body 100;

[0064] S3. Fixing the electrical connector body 100: After the protective component 200 is assembled to the electrical connector body 100, the connection terminals of the socket 110 and the plug 120 respectively squeeze the corresponding clamping plate 410, so that the clamping plate 410 drives one end of the connecting plate 420 to move, so that the bevel angle of the connecting plate 420 changes, and the other end of the connecting plate 420 slides in the inner cavity of the slide groove 500 and drives the guide wheel 440 to roll in the inner cavity of the guide groove 600, and the connecting plate 420 squeezes the second spring 432 and the damper 431, so that the second spring 432 is forced to contract.
