Description

Technical Field

[0001] The present application relates to the technical field of power distribution equipment, and in particular to a latch device for quick assembly and disassembly of a pole-mounted switch and an electronic module. Background Art

[0002] Pole switch is a kind of power equipment, usually used in medium and high voltage power system, which is a mechanical switch that can close and open a certain load current. Pole switch is an important part of the power system, and its stability and reliability are crucial to the safe operation of the entire power system.

[0003] The feeder terminal (FTU) is a distribution automation terminal (i.e., electronic module) with telesignaling, telemetering, remote control, and feeder automation functions. It and the pole switch are the two core devices in the field of distribution automation. Due to the mismatch in service life between the pole switch, which is mainly a mechanical device, and the feeder terminal (FTU), which is mainly electronic components, these two devices are relatively independent. Usually, the pole switch is called the primary device, and the feeder terminal is called the secondary device.

[0004] The pole switches in related technologies, including the primary and secondary fusion pole switches launched in recent years, simply "fuse" some sensors and electronic components with long service life such as inductors, resistors, ceramic capacitors, etc. into the pole switches. If the feeder terminal is directly installed on the pole switch, it will be very inconvenient to disassemble and install it during maintenance.

[0005] Therefore, the pole-mounted switches in related technologies lack a reliable and fast loading and unloading structure, which will affect the application of feeder terminals (i.e., electronic modules) in pole-mounted switches, affect the deep integration of primary and secondary equipment, and further restrict the intelligence of pole-mounted switches. Utility Model Content

[0006] In order to improve the problem of the existing pole-mounted switch lacking a reliable and fast assembly and disassembly structure, the present application provides a latch device for fast assembly and disassembly of a pole-mounted switch and an electronic module.

[0007] The present application provides a latch device for quick assembly and disassembly of a column switch and an electronic module, which adopts the following technical solution:

[0008] A latch device for quick assembly and disassembly of a pole-mounted switch and an electronic module, comprising an outer box arranged on the pole-mounted switch, a fixed bracket arranged inside the outer box, a quick assembly and disassembly box for mounting a feeder terminal arranged on the fixed bracket, a connecting block arranged on the outer box, a latch hole arranged on the connecting block, a supporting block arranged inside the fixed bracket, a fixed sleeve passed through the supporting block, a latch slidably arranged inside the fixed sleeve, the latch slidably fits in the fixed sleeve in a direction approaching or moving away from the connecting block, the latch is plugged and fitted in the latch hole, an end of the latch away from the latch hole is sleeved with a rotating swing arm for driving the latch to move in a direction approaching or moving away from the connecting block, an elastic member is arranged on the latch, one end of the elastic member is connected to the latch, and the other end of the elastic member is connected to the fixed sleeve.

[0009] By adopting the above technical solution, during disassembly, the connection between the feeder terminal and the pole switch is disconnected, and the bolt is moved in the direction close to or away from the connection block and extended out of the bolt hole by driving the rotating swing arm to compress the elastic member, so that the quick loading and unloading box can be disassembled and the quick loading and unloading box can be taken out of the outer box to achieve quick disassembly. During installation, the quick loading and unloading box is placed in the outer box, and the rotating swing arm is driven to reset, so that the bolt is reset. At this time, the elastic member is released, and the bolt is reset by the elastic force of the elastic member, so that the bolt is extended into the bolt hole, and then the feeder terminal is connected to the pole switch, and the quick loading and unloading box can be installed on the box body, thereby preventing the application of the feeder terminal on the pole switch from being affected, that is, preventing the deep integration of primary and secondary equipment from being affected, and thus facilitating the intelligentization of the pole switch.

[0010] Preferably, the rotating swing arm is rotatably disposed on a fixed sleeve, and a movable inclined surface is disposed at one end of the fixed sleeve close to the rotating swing arm, wherein the movable inclined surface includes an inclined bottom end and an inclined top end, and one end of the rotating swing arm abuts against the inclined bottom end of the movable inclined surface.

[0011] By adopting the above technical solution, when the rotating swing arm is driven to rotate along the inclined bottom end of the movable inclined surface toward the inclined top end, the pin is moved in the direction close to or away from the connecting block, and the pin is extended into or out of the pin hole, and the quick-loading and unloading box is disassembled to facilitate the replacement of the feeder terminal in the quick-loading and unloading box.

[0012] Preferably, the rotating swing arm includes a rotating sleeve sleeved on the pin and an operating swing arm connected to the rotating sleeve at one end. The rotating sleeve is rotatably arranged in the fixed sleeve and slidingly cooperates with the fixed sleeve. One side of the operating swing arm abuts against the movable inclined surface.

[0013] By adopting the above technical solution, during disassembly, by driving the operating swing arm to rotate along the movable inclined plane, the latch can be conveniently driven to move along the length direction of the fixed sleeve, thereby making it more convenient and quick to load and unload the box.

[0014] Preferably, a driving component for driving the loading and unloading component for installation or disassembly is arranged between the fixed bracket and the outer box, and the driving component includes a nut passing through the outer box and an operating rod movably arranged on the outer box, and a screw is arranged at one end of the operating rod, and the screw thread is engaged with the nut, and one end of the screw extends into the fixed bracket and is aligned with the operating swing arm.

[0015] By adopting the above technical solution, when the operating rod is driven to rotate, the screw moves along the length direction of the operating rod, and the screw abuts and drives the operating swing arm to rotate, which is conducive to driving the quick loading and unloading box from the outside of the outer box through the operating rod for installation and disassembly, and prevents accidental contact with the operating swing arm to rotate, causing the pin to disengage from the pin hole.

[0016] Preferably, the elastic member comprises a spring, and the spring is sleeved on the latch.

[0017] By adopting the above technical solution, the bolt is connected to the fixed sleeve through the spring to prevent the bolt from falling off the fixed sleeve, and when the bolt is inserted into the bolt hole, the elastic force of the spring makes the bolt more stably inserted into the bolt hole.

[0018] Preferably, a reinforcement sleeve is further provided at one end of the support block close to the fixing sleeve, and the fixing sleeve is also passed through the reinforcement sleeve.

[0019] By adopting the above technical solution, the supporting area is increased, so that the fixing sleeve can be more stably arranged on the supporting block.

[0020] Preferably, the outer box comprises a box body and a box cover, one end of the box body is open, the fixing bracket and the quick-loading and disassembly box are located in the box body, and the box cover is covered on the box body.

[0021] By adopting the above technical solution, the quick-loading and unloading box in the box body can be conveniently placed or taken out by opening or closing the box cover.

[0022] Preferably, a docking port is provided at one end of the quick-loading and disassembly box, the docking port is communicated with the quick-loading and disassembly box, and the docking port is used to connect the feeder terminal inside the quick-loading and disassembly box with the pole switch.

[0023] By adopting the above technical solution, the feeder terminal inside the quick-mounting and disassembly box can be conveniently electrically connected or disassembled with the pole switch through the docking interface.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. When disassembling, open the box cover, disconnect the feeder terminal from the pole switch through the docking interface, drive the operating lever to rotate, and through the cooperation of the screw and the nut, make the screw abut and drive the operating swing arm to rotate, so that the operating swing arm moves along the inclined bottom end of the active inclined surface to the inclined top end, so that the latch moves along the length direction of the fixed sleeve and extends out of the latch hole, the spring is compressed, and the quick loading and unloading box can be disassembled, and the quick loading and unloading box is taken out from the opening end of the box body to achieve quick disassembly;

[0026] 2. During installation, by placing the quick-loading and disassembly box in the box body, driving the operating lever to reset, the screw is reset, and the spring is released at this time. The elastic force of the spring resets the latch, so that the latch extends into the latch hole, and the feeder terminal is connected to the pole switch through the docking interface. The quick-loading and disassembly box can be installed in the box body, thereby preventing the application of the feeder terminal on the pole switch from being affected, that is, preventing the deep integration of primary and secondary equipment from being affected, which is beneficial to the intelligence of the pole switch.

The latch 43 is also sleeved with a spring 51, which is distributed along the length direction of the long slot 431. One end of the spring 51 is connected to the slot wall of the long slot 431 away from the rotating swing arm 48, and the other end of the spring 51 is connected to the cavity wall of the sliding cavity 47 close to the rotating swing arm 48, so that the latch 43 is connected to the fixed sleeve 42 through the spring 51 to prevent the latch 43 from falling off the fixed sleeve 42, and when the latch 43 is inserted into the latch hole 46, the elastic force of the spring 51 makes the latch 43 more stably inserted into the latch hole 46. When the driving operating rod 50 rotates, that is, the latch 43 moves, the spring 51 is compressed, and when the driving operating rod 50 is reset, the spring 51 is released, and the latch 43 is reset by the elastic force of the spring 51, so that the latch 43 is inserted into the latch hole 46.

[0043] During disassembly, the operating rod 50 is driven to rotate, and the screw rod 501 cooperates with the nut 49 to make the screw rod 501 contact and drive the operating swing arm 481 to rotate, so that the operating swing arm 481 moves along the inclined bottom end 4211 of the movable inclined surface 421 to the inclined top end 4212, so that the latch 43 moves along the length direction of the fixed sleeve 42 and extends out of the latch hole 46, and the spring 51 is compressed, and the quick-loading and disassembly box 3 is disassembled. During installation, the operating rod 50 is driven to reset, so that the screw rod 501 is reset, and the spring 51 is released at this time, and the latch 43 is reset by the elastic force of the spring 51, so that the latch 43 is plugged into the latch hole 46, and the quick-loading and disassembly box 3 can be installed in the box body 11.

[0044] In addition, refer to Figure 1A docking port 5 is provided at one end of the quick-loading and disassembly box 3 away from the fixed bracket 2. The docking port 5 is circular and connected to the quick-loading and disassembly box 3. The docking port 5 is used to connect the feeder terminal (i.e., the electronic module) inside the quick-loading and disassembly box 3 with the pole switch. The docking port 5 is distributed along the length direction of the quick-loading and disassembly box 3, so that the feeder terminal (i.e., the electronic module) inside the quick-loading and disassembly box 3 and the pole switch can be conveniently electrically connected through the docking port 5.

[0045] The implementation principle of the present application is as follows: when disassembling, the box cover 12 is opened, the connection between the feeder terminal and the pole switch is disconnected through the docking interface 5, the operating rod 50 is driven to rotate, and the screw 501 is matched with the nut 49 to make the screw 501 abut and drive the operating swing arm 481 to rotate, so that the operating swing arm 481 moves along the inclined bottom end 4211 of the active inclined surface 421 to the inclined top end 4212, so that the latch 43 moves along the length direction of the fixed sleeve 42 and extends out of the latch hole 46, and the spring 51 is compressed, so that the quick-loading and unloading box 3 is disassembled, and the quick-loading and unloading box 3 is removed from the box When installing, by placing the quick-loading and disassembly box 3 on the box body 11, the operating lever 50 is driven to reset, so that the screw 501 is reset, and the spring 51 is released at this time, and the latch 43 is reset by the elastic force of the spring 51, so that the latch 43 extends into the latch hole 46, and the feeder terminal is connected to the pole switch through the docking interface 5, the quick-loading and disassembly box 3 can be installed on the box body 11, so as to prevent affecting the application of the feeder terminal on the pole switch, that is, to prevent affecting the deep integration of primary and secondary equipment, which is beneficial to the intelligence of the pole switch.
