Technical Field
[0001] This application relates to the field of pole-mounted switches, and particularly to a self-locking structure for quick loading and unloading of electronic modules of pole-mounted switches. Background Art
[0002] A pole-mounted switch is a mechanical device commonly used outdoors and installed on the top of a utility pole, which is used to close and disconnect the load current and is called a primary device. Corresponding to the primary device, a feeder terminal unit (FTU) is called a secondary device, which is an electronic device used for measuring, protecting, and monitoring the operation of the primary device. In the existing related technologies, in order to promote the automation and intellectualization of distribution facilities, the electronic module of the secondary device is usually installed in the protection outer box of the pole-mounted switch through bolts and forms a new type of integrated primary and secondary pole-mounted switch with the pole-mounted switch, i.e., the primary device.
[0003] In view of the above related technologies, the disassembly and assembly of the electronic module of the secondary device are relatively inconvenient, which is not conducive to the maintenance of the pole-mounted switch and affects the popularization of the new type of pole-mounted switch. Summary of the Invention
[0004] In order to facilitate the disassembly and assembly of the electronic module of the feeder terminal unit and thus reduce the maintenance cost of the pole-mounted switch, this application provides a self-locking structure for quick loading and unloading of the electronic module of the pole-mounted switch.
[0005] The self-locking structure for quick loading and unloading of the electronic module of the pole-mounted switch provided by this application adopts the following technical solutions:
[0006] A self-locking structure for quick loading and unloading of the electronic module of the pole-mounted switch includes a protection outer box, a quick loading and unloading box, a self-locking component, and a driving component; the protection outer box is provided with a locking jack, and the quick loading and unloading box is used to accommodate the electronic module of the feeder terminal unit;
[0007] The self-locking component includes a self-locking seat body, a self-locking slider, and a driving ejector rod. The self-locking seat body is installed on the quick loading and unloading box. The self-locking slider is slidably matched with the self-locking seat body. The self-locking slider is provided with a slider inclined surface. The driving ejector rod is slidably matched with the self-locking seat body. The driving ejector rod is installed with a driving shaft pin, and the driving shaft pin is in abutting fit with the slider inclined surface;
[0008] When the driving shaft pin slides along the slider inclined surface, the self-locking slider moves in a direction close to or away from the locking jack, and the driving component is used to make the driving shaft pin move along the slider inclined surface.
[0009] By adopting the above technical solution, when it is necessary to remove the feeder terminal electronic module, the driving shaft pin slides along the inclined surface of the slider through the driving component, so that the self-locking slider is pulled out from the locking jack, and then the electronic module in the quick loading and unloading box can be quickly and conveniently removed from the protective outer box, effectively solving the problem of frequent maintenance due to the mismatch of the service lives of mechanical parts and electronic components between the pole-mounted switch mainly composed of mechanical parts and the electronic module mainly composed of electronic components, facilitating the maintenance personnel to carry out maintenance and reducing the maintenance cost of the pole-mounted switch.
[0010] Optionally, the driving component includes a first reset member, a second reset member and an operating rod. Both the first reset member and the second reset member have elasticity. Two ends of the first reset member are respectively installed on the self-locking slider and the self-locking seat body. Two ends of the second reset member are respectively installed on the driving ejector rod and the self-locking seat body. The operating rod is movably matched with the quick loading and unloading box along the sliding direction of the driving ejector rod.
[0011] By adopting the above technical solution, when the operating rod presses against the driving ejector rod along the sliding direction of the driving ejector rod, the driving shaft pin slides along the inclined surface of the slider, so that the self-locking slider disengages from the locking jack, thus conveniently unlocking the self-locking slider. When the operating rod moves away from the driving ejector rod along the sliding direction of the driving ejector rod, the first reset member makes the self-locking slider move towards the position where the locking jack is located, and the second reset member drives the driving shaft pin to slide reversely along the inclined surface of the slider through the driving ejector rod, and then inserts the self-locking slider into the locking jack, thus conveniently completing the disassembly and assembly of the quick loading and unloading box.
[0012] Optionally, the operating rod is movably matched with the protective outer box along the sliding direction of the driving ejector rod through a fixing nut. The fixing nut is installed on the quick loading and unloading box, and the operating rod is in threaded fit with the fixing nut.
[0013] By adopting the above technical solution, after the operating rod makes the driving shaft pin reach the position where the inclined surface of the slider is located, self-locking is carried out through the thread, omitting the locking structure with complex structure, having a simple, reliable and durable structure and strong adaptability to the complex outdoor environment.
[0014] Optionally, one end of the operating rod close to the driving ejector rod is located inside the protective outer box, and the other end of the operating rod away from the driving ejector rod is located outside the protective outer box.
[0015] By adopting the above technical solution, it is convenient for the maintenance personnel to operate the operating rod outside the protective outer box with a larger working surface, and the maintenance difficulty is lower.
[0016] Optionally, the self-locking seat body is provided with a seat body chute. The seat body chute is located inside the self-locking seat body. The self-locking slider is located in the seat body chute, and the self-locking slider is slidably matched with the self-locking seat body through the seat body chute.
[0017] By adopting the above technical solution, the self-locking slider slides through the seat chute inside the self-locking seat body, making the sliding movement of the self-locking slider relatively stable and not easily displaced due to shaking under the action of wind.
[0018] Optionally, a push rod chute is provided on the inner wall of the seat chute, the push rod chute penetrates through the self-locking seat body, and the driving push rod is slidably matched with the push rod chute.
[0019] By adopting the above technical solution, the driving push rod slides through the push rod chute on the inner wall of the seat chute, making the sliding movement of the driving push rod relatively stable and not easily displaced due to shaking under the action of wind.
[0020] Optionally, a slider chute is provided through the self-locking slider, and the slider inclined surface is located in the slider chute.
[0021] By adopting the above technical solution, the self-locking slider is locked with the driving push rod through the driving shaft pin, making it difficult for both the self-locking slider and the driving push rod to disengage from the self-locking seat body.
[0022] Optionally, one end of the self-locking slider close to the locking jack is provided with a plugging inclined surface.
[0023] By adopting the above technical solution, it is convenient for the self-locking slider to be inserted into the locking jack through the plugging inclined surface.
[0024] Optionally, the quick loading and unloading box accommodates the electronic module of the feeder terminal through the loading and unloading cavity opened inside itself, and the quick loading and unloading box is provided with an interface for electrically connecting the electronic module in the loading and unloading cavity to the pole-mounted switch.
[0025] By adopting the above technical solution, it is convenient for the maintenance personnel to pull out the cable from the interface, so that the maintenance of the electronic module of the feeder terminal can be carried out under the live state of the pole-mounted switch, improving the maintenance efficiency.
[0026] In summary, the present application includes at least one of the following beneficial technical effects:
[0027] 1. When it is necessary to remove the electronic module of the feeder terminal, the driving shaft pin is made to slide along the slider inclined surface through the driving component, so that the self-locking slider is pulled out from the locking jack, and then the electronic module in the quick loading and unloading box can be quickly and conveniently removed from the protection outer box, effectively solving the problem of frequent maintenance due to the mismatch of the service lives of mechanical parts and electronic components between the pole-mounted switch mainly composed of mechanical parts and the electronic module mainly composed of electronic components, facilitating the maintenance personnel to carry out inspection and maintenance, and reducing the maintenance cost of the pole-mounted switch;
[0028] 2. When the operating rod abuts tightly against the driving ejector rod along the sliding direction of the driving ejector rod, the driving shaft pin slides along the inclined surface of the slider, causing the self-locking slider to disengage from the locking jack, thus conveniently unlocking the self-locking slider. When the operating rod moves away from the driving ejector rod along the sliding direction of the driving ejector rod, the first resetting member causes the self-locking slider to move towards the position where the locking jack is located, and the second resetting member drives the driving shaft pin to slide reversely along the inclined surface of the slider through the driving ejector rod, thereby inserting the self-locking slider into the locking jack, thus conveniently completing the disassembly and assembly of the quick loading and unloading box;

[0034] The following will further describe the present application in detail with reference to the attached Figures 1-3 drawings.
[0035] The embodiment of the present application discloses a self-locking structure for quick loading and unloading of a pole-mounted switch electronic module. Referring to Figure 1 , the self-locking structure for quick loading and unloading of a pole-mounted switch electronic module includes a protective outer box 1, a quick loading and unloading box 2, a self-locking component 3, and a driving component 4.

The quick loading and unloading box 2 and the self-locking component 3 are both located inside the outer box cavity 101, and the protective outer box 1 is fastened with an outer box cover 11 for closing the outer box cavity 101.
[0037] Referring toFigure 1 , the quick loading and unloading box 2 accommodates the electronic module of the feeder terminal through the loading and unloading cavity 201 opened inside itself. A docking interface 21 is fixedly installed at the top of the quick loading and unloading box 2. The docking interface 21 is used to electrically connect the electronic module in the loading and unloading cavity 201 to the pole-mounted switch outside, so as to connect or disconnect the electrical connection between the electronic module and the pole-mounted switch during maintenance, thereby facilitating the maintenance of the electronic module when the pole-mounted switch is energized.
[0038] Refer to Figure 1 , a fixing frame 22 is fixedly installed at the bottom of the quick loading and unloading box 2, so that the quick loading and unloading box 2 can be placed in the outer box cavity 101 through the fixing frame 22. The self-locking assembly 3 is installed on the quick loading and unloading box 2 through the fixing frame 22. The self-locking assembly 3 includes a self-locking seat body 31, a self-locking slider 32 and a driving ejector rod 33;
[0039] Refer to Figure 2 , the self-locking seat body 31 is fixedly installed on the fixing frame 22. The self-locking seat body 31 is provided with a seat body chute 3101. The seat body chute 3101 is located inside the self-locking seat body 31, and the seat body chute 3101 extends horizontally through to one end of the self-locking seat body 31. A locking socket 102 is opened on the inner wall of the outer box cavity 101, and the locking socket 102 is arranged facing the seat body chute 3101. The self-locking slider 32 is located in the seat body chute 3101, and the self-locking slider 32 is slidably matched with the self-locking seat body 31 through the seat body chute 3101. One end of the self-locking slider 32 close to the locking socket 102 is provided with a plugging inclined surface 321. Specifically, in the embodiment of the present application, the plugging inclined surface 321 is inclined downward and toward the direction close to the locking socket 102, so as to facilitate the self-locking slider 32 to be inserted into the locking socket 102 through the guiding and sliding action of the plugging inclined surface 321.
[0040] Refer to Figure 2 and Figure 3 , the self-locking slider 32 is provided with a slider chute 3201 in a penetrating manner. The inner wall of the slider chute 3201 is provided with a slider inclined surface 322. Specifically, in the embodiment of the present application, the slider inclined surface 322 is inclined downward and toward the direction close to the bottom of the seat body chute 3101.
[0041] The inner wall of the seat chute 3101 is provided with ejector rod chutes 3102. There are two ejector rod chutes 3102 (not shown in the figure). The two ejector rod chutes 3102 are arranged opposite to each other, and both of the two ejector rod chutes 3102 penetrate through the self-locking seat body 31 in the vertical direction. The two ejector rod sliding parts 331 of the driving ejector rod 33 are respectively slidably matched with the two ejector rod chutes 3102 in the vertical direction to ensure the sliding stability of the driving ejector rod 33. The two ejector rod sliding parts 331 are rotatably matched with a driving shaft pin 5 through pin holes formed in themselves. The cross section of the driving shaft pin 5 is circular. The driving shaft pin 5 is located in the slider chute 3201, and the driving shaft pin 5 is tightly abutted and matched with the slider inclined surface 322, so as to facilitate the driving shaft pin 5 to slide along the slider inclined surface 322 through the driving ejector rod 33, and further enable the self-locking slider 32 to move towards or away from the locking jack 102, so that the self-locking slider 32 is inserted into the locking slot or disengaged from the locking slot.
[0042] Referring to Figure 2 , the driving assembly 4 includes a first reset member 41, a second reset member 42 and an operating rod 43. Both the first reset member 41 and the second reset member 42 are elastic. In the embodiment of the present application, both the first reset member 41 and the second reset member 42 are selected as springs. The first reset member 41 is located in the seat chute 3101, and both ends of the first reset member 41 are respectively installed on the self-locking slider 32 and the self-locking seat body 31, and the first reset member 41 is arranged in the horizontal direction. Both ends of the second reset member 42 are respectively installed on the driving ejector rod 33 and the self-locking seat body 31, and the second reset member 42 is arranged in the vertical direction.
[0043] Referring to Figure 1 and Figure 3 , the operating rod 43 is movably matched with the protection outer box 1 along the sliding direction of the driving ejector rod 33 through a fixing nut 431. Specifically, in the embodiment of the present application, the operating rod 43 is movably matched with the protection outer shell in the vertical direction. The fixing nut 431 is fixedly installed at the bottom of the quick loading and unloading box 2 and is located at the bottom of the driving ejector rod 33. The top of the operating rod 43, that is, the end close to the driving ejector rod 33, is threadedly matched with the fixing nut 431 and is located inside the protection outer box 1, and the bottom of the operating rod 43, that is, the end far from the driving ejector rod 33, is located outside the protection outer box 1, so as to facilitate the driving ejector rod 33 to move in the vertical direction by rotating the operating rod 43 outside the protection outer box 1.
[0044] The implementation principle of the self-locking structure for quick loading and unloading of the pole-mounted switch electronic module in the embodiment of the present application is as follows: when it is necessary to remove the feeder terminal electronic module, the cable used to electrically connect the electronic module to the pole-mounted switch is pulled out from the docking interface 21, and then the driving shaft pin 5 is made to slide along the slider inclined surface 322 by rotating the operating rod 43, so that the self-locking slider 32 is pulled out from the locking jack 102, and further the electronic module in the quick loading and unloading box 2 can be quickly and conveniently removed from the protection outer box 1.
[0045] When the feeder terminal electronic module needs to be installed, the quick loading and unloading box 2 is placed in the outer box cavity 101 through the fixing frame 22. Then, by rotating the operating rod 43, the driving shaft pin 5 slides reversely along the slider inclined surface 322, so that the self-locking slider 32 is inserted into the locking jack 102. Furthermore, the electronic module in the quick loading and unloading box 2 can be quickly and conveniently installed from the protection outer box 1, effectively solving the problem of frequent maintenance due to the mismatch of the service lives of mechanical parts and electronic components between the pole-mounted switch mainly composed of mechanical parts and the electronic module mainly composed of electronic components, facilitating the maintenance personnel to carry out inspection and maintenance, and reducing the maintenance cost of the pole-mounted switch.
[0046] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
