Description

Technical Field

[0001] This utility model belongs to the technical field of reclosing protectors, and specifically relates to a reclosing protector. Background Technology

[0002] A reclosing device is a device used in power systems. When a transient fault in a line or equipment causes a protective trip, the reclosing device closes the circuit again within a predetermined time interval, restoring power supply. Reclosing is an automated mechanism used to handle potential transient faults, aiming to reduce unnecessary power outages and improve power supply reliability.

[0003] Existing reclosing protectors typically consist of a housing and components housed within it. During actual installation, some reclosing protectors are fixed to the guide rail via grooves on the housing and inserts that pass through it. These inserts are either manually pushed or automatically ejected. Manually pushed inserts may not be fully pushed in, affecting the fixing effect. Automatically ejected inserts provide better fixing, but a single reclosing protector usually has multiple inserts, requiring simultaneous operation to easily remove the reclosing protector from the guide rail, which is rather cumbersome. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a reclosing protector that is more convenient to fix to the guide rail and easier to remove than the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a reclosing protector, comprising a housing and a plug-in, wherein the housing comprises a front and a back side disposed opposite to each other, the back side is provided with a groove, and the two opposite groove walls of the groove are respectively provided with a protrusion and a socket for inserting the plug-in, the plug-in is square ring-shaped, the end of the plug-in facing the protrusion is provided with a limiting end, the opening of the socket facing the protrusion is provided with a notch, the limiting end is provided with a limiting part that forms a limiting with the notch, the plug-in is provided with a wave-shaped elastic part, the end of the elastic part near the protrusion is fixed to the limiting part, the socket is provided with a stepped surface for the end of the elastic part away from the limiting part to abut, a limiting member is provided between the socket and the plug-in to prevent the plug-in from coming out of the opening of the socket facing the protrusion, a fixing groove is provided at the opening of the socket away from the protrusion, and a fixing block is provided on the plug-in that can form a limiting with the fixing groove.

[0006] Using the above scheme, when no external force is applied, the fixing block is located inside the insertion hole. "No external force" means that the operator does not apply force to the plug-in. During assembly, the plug-in is inserted into the insertion hole near the protrusion. In actual use, force is applied to the limiting end via the guide rail, causing the plug-in to move away from the protrusion, facilitating the movement of the guide rail away from the insertion hole until it forms a limiting position with the protrusion. After the guide rail and protrusion form a limiting position, the plug-in moves towards the protrusion under the action of the elastic part, at which point the fixing block is located inside the insertion hole. In this embodiment, the plug-in remains fixed to the guide rail under the action of the protrusion and the limiting end.

[0007] When it is necessary to remove this utility model, apply force to the plug-in with a tool to move the plug-in away from the protrusion. After the fixed block is disengaged from the insertion hole, push the plug-in towards the fixed groove until the fixed block is embedded in the fixed groove. Then release the plug-in. The fixed block remains embedded in the fixed groove under the action of the elastic part, which can prevent the plug-in from moving towards the protrusion. After all the plug-in operations are completed, this utility model can be easily removed from the guide rail.

[0008] Compared to existing technologies, the plug-in of this invention automatically pops out under the action of the elastic part, ensuring a secure hold. When removal is needed, it is not necessary to operate all plug-ins simultaneously, making the operation more convenient.

[0009] As a further feature of this utility model, the limiting member includes a sliding groove and a movable arm. The sliding groove is disposed on the wall of the insertion hole. The end of the movable arm near the protrusion is connected to the plug, and the end away from the protrusion is provided with a locking part that limits the sliding groove. There is a gap between the movable arm and the plug.

[0010] Using the above solution, the movable arm deforms under force when the plug is inserted into the socket, facilitating insertion. After insertion, the locking part is engaged in the groove by the movable arm, preventing the plug from automatically detaching from the socket towards the protrusion. To remove the plug, apply force to the movable arm with a tool to disengage the locking part from the groove, then push the end of the plug away from the protrusion to detach it from the socket towards the protrusion.

[0011] As a further feature of this invention, the snap-fit ​​portion is formed by bending the end of the movable arm away from the protrusion toward the protrusion.

[0012] The above solution facilitates processing and ensures the proper fit between the snap-fit ​​part and the slide groove.

[0013] As a further feature of this invention, the plug-in is provided with a second step surface that can be positioned to limit the movement of the first step surface.

[0014] By adopting the above solution, the shape of the plug-in is better adapted to the socket, allowing the plug-in to move more stably within the socket.

[0015] As a further feature of this invention, the end of the fixing block away from the plug extends toward the protrusion, and the bottom of the fixing groove extends toward the protrusion.

[0016] The above solution ensures the proper fit between the fixing block and the fixing groove.

[0017] As a further feature of this invention, the fixing groove is located on the side of the insertion hole closer to the front.

[0018] The above solution makes it easy for operators to embed the fixing block into the fixing groove.

[0019] The present invention will now be further described with reference to the accompanying drawings. Attached Figure Description

[0029] Specific embodiments of this utility model are shown in the accompanying drawings.

[0030] A reclosing protector includes a housing 1 and a plug 2. The housing 1 includes a front side 11 and a back side 12 arranged opposite to each other. The back side 12 is provided with a groove 13. The two opposite groove walls of the groove 13 are respectively provided with a protrusion 14 and a socket 15 for the plug 2 to be inserted. The plug 2 is square and annular. The end of the plug 2 facing the protrusion 14 is provided with a limiting end 21. The opening of the socket 15 facing the protrusion 14 is provided with a notch 16. The limiting end 21 is provided with a limiting part 211 that forms a limiting with the notch 16. The plug 2 is provided with a wave-shaped elastic part 22. The end of the elastic part 22 near the protrusion 14 is fixed to the limiting part 211. The socket 15 is provided with a stepped surface 151 for the end of the elastic part 22 away from the limiting part 211 to abut. The opening of the socket 15 away from the protrusion 14 is provided with a fixing groove 17. The plug 2 is provided with a fixing block 23 that can form a limiting with the fixing groove 17. The wall of the socket 15 is provided with a groove 152, and the plug-in 2 is provided with a movable arm 24 extending away from the protrusion 14. The end of the movable arm 24 away from the protrusion 14 is provided with a locking part 25 that limits the movement of the groove 152. There is a gap between the movable arm 24 and the plug-in 2. When no external force is applied, the fixing block 23 is located inside the socket 15. No external force is applied means that the operator does not apply force to the plug-in 2.

[0031] During assembly, insert the plug 2 into the hole 15 near the opening of the protrusion 14. When the plug 2 is inserted, the movable arm 24 deforms under force, facilitating insertion. After insertion, the locking part 25, under the action of the movable arm 24, embeds into the sliding groove 152, preventing the plug 2 from automatically detaching from the hole 15 towards the opening of the protrusion 14. In actual use, force is applied to the limiting end 21 via the guide rail, causing the plug 2 to move away from the protrusion 14, facilitating the movement of the guide rail away from the hole 15 until it forms a limiting position with the protrusion 14. After the guide rail forms a limiting position with the protrusion 14, the plug 2 moves towards the protrusion 14 under the action of the elastic part 22, at which point the fixing block 23 is located inside the hole 15. In this embodiment, the protrusion 14 and the limiting end 21 keep the plug 2 fixed to the guide rail.

[0032] When it is necessary to disassemble this embodiment, apply force to the plug 2 with a tool to move the plug 2 away from the protrusion 14. After the fixing block 23 is disengaged from the insertion hole 15, push the plug 2 towards the fixing groove 17 until the fixing block 23 is embedded in the fixing groove 17. Then release the plug 2. The fixing block 23 remains embedded in the fixing groove 17 under the action of the elastic part 22, which can prevent the plug 2 from moving towards the protrusion 14. After all the plug 2 operations are completed, this embodiment can be easily removed from the guide rail.

[0033] When it is necessary to remove the plug 2, apply force to the movable arm 24 with a tool to make the snap-fit ​​part 25 leave the slide groove 152, and then push the plug 2 away from the end of the protrusion 14 to detach the plug 2 from the hole 15 toward the hole of the protrusion 14.

[0034] Compared to existing technologies, in this embodiment, the plug 2 automatically pops out under the action of the elastic part 22, ensuring a secure fixation effect. When removal is required, it is not necessary to operate all plugs 2 simultaneously, making the operation more convenient.

[0035] The snap-fit ​​part 25 is formed by bending the end of the movable arm 24 away from the protrusion 14 towards the protrusion 14. This facilitates processing and ensures the proper fit between the snap-fit ​​part 25 and the slide groove 152.

[0036] The plug-in 2 is provided with a step surface 26 that can be limited by the step surface 151. This makes the shape of the plug-in 2 more compatible with the socket 15, and allows the plug-in 2 to move more stably within the socket 15.

[0037] The end of the fixing block 23 furthest from the plug-in 2 extends towards the protrusion, and the bottom of the fixing groove 17 extends towards the protrusion 14. This ensures the proper fit between the fixing block 23 and the fixing groove 17.

[0038] The fixing groove 17 is located on the side of the insertion hole 15 near the front 11. This allows the operator to easily insert the fixing block 23 into the fixing groove 17.

[0039] This utility model is not limited to the specific embodiments described above. Those skilled in the art can implement this utility model using other specific embodiments based on the content disclosed in this utility model. Any simple changes or modifications made to the design structure and concept of this utility model will fall within the protection scope of this utility model.
