Description

Technical Field

[0001] The utility model relates to the technical field of electric energy meters, in particular to a button-type flipping locking module for an electric energy meter connector. Background Art

[0002] At present, most of the electric energy meter connectors adopt a flipping structure. The flipping form mostly fixes the base to the meter box and drives the flipping backplane or the electric meter to drive the flipping backplane to perform opening and closing operations. To realize the opening and closing functions, the connectors mostly adopt the form of embedding metal wire springs or elastic pieces on the base or the flipping backplane to complete. This increases the assembly process of metal parts and plastic parts, and at the same time reduces the production efficiency of the electric energy meter connector.

[0003] For example, the publication number "CN117054711A" discloses "an electric energy meter plug-in connector", which includes a base, a rotating bracket is connected to the base, a conductive part is arranged on the rotating bracket, the conductive part is detachably connected to an electric energy meter, and when the rotating bracket rotates, it synchronously drives the conductive part and the electric energy meter to rotate. An opening and closing switch is arranged on the base. When the rotating bracket drives the conductive part to abut against the opening and closing switch, the conductive part is energized with the electric energy meter. However, in actual application, the functions of the base backplane and the meter box backplane overlap, which increases the materials required for production, raises the production cost, increases the weight, and is not convenient for subsequent transportation and assembly. Summary of the Invention

[0004] Aiming at the problems of high consumable costs and inconvenient subsequent assembly and transportation existing in the prior art mentioned in the background art, the utility model provides a button-type flipping locking module for an electric energy meter connector, which can reduce the materials required for production, and at the same time reduce the weight and facilitate subsequent transportation and assembly.

[0005] To achieve the above object, the utility model adopts the following technical solutions.

[0006] A button-type flipping locking module for an electricity meter connector, comprising a locking seat arranged on a flipping plate of the connector. A button locking unit is detachably connected to the locking seat. A fitting groove is arranged on the locking seat. The button locking unit is connected to the locking seat and fitted in the fitting groove. The button locking unit is connected to the back panel of the meter box, and the locking seat flips synchronously with the flipping plate. A fitting groove is arranged on the locking seat and is connected to the button locking unit. The opening area of the fitting groove is larger than the area of the button locking unit. During use, since the fitting groove can accommodate the button locking unit, the button locking unit can be fitted inside the fitting groove during installation, ensuring the stability of the connection. At the same time, it can leave space for thickening the dimensions of the rest of the locking seat. Since the locking seat is connected to the flipping plate, the thickness of the flipping plate can be made thicker, improving the structural strength. At the same time, since the button locking unit is a unit module and is only connected to the back panel of the meter box, while ensuring the stability of the flipping plate through the back panel of the meter box, no connection relationship is generated with other components, simplifying the structure of the original base back panel, facilitating production and assembly, and being able to attach the button locking unit to the locking seat, that is, synchronously connect it to the flipping plate for factory shipment. Since the button locking unit is only connected to the back panel of the meter box and is detachably connected to the locking seat by clamping, the connection parts with the fixed base are reduced, saving production consumables. And it is convenient for subsequent maintenance and replacement. Only the damaged button locking unit needs to be replaced, avoiding replacing large-sized components such as the flipping plate and the fixed bottom plate with complex connection relationships, and having better flexibility.

[0007] Preferably, the button locking unit includes a back panel, and a hook is arranged on one side of the back panel facing the locking seat. A groove for clamping and connecting the hook is arranged on the locking seat. A groove is arranged on the locking seat, and a hook is arranged on the button locking unit. Through this setting, the connection position of the hook and the groove can be arranged inside the fitting groove, thus making full use of the internal space of the fitting groove. Therefore, it is avoided to set the connection position close to the back panel of the meter box, reducing interference. During the connection process, the hook on the button locking unit needs to be deformed frequently. Relatively, the groove on the locking seat has a relatively small amount of deformation, and the probability of deformation and damage of the hook is relatively large. Therefore, the hook needs to be replaced and repaired frequently. Setting the hook on the button locking unit can reduce the subsequent maintenance cost. The button locking unit can also be made of a high-strength material, including but not limited to metal, so as to improve the service life of the hook, ensure that the production cost is controllable, and be able to control the overall weight and production cost.

[0008] Preferably, the button locking unit includes a back panel, and the back panel is connected to the fitting groove with a gap. The gap left between the back panel and the fitting groove can ensure the smoothness of the butt joint.

[0009] Preferably, a deformation hollow area is provided on the back plate, and the deformation hollow area is arranged near the root of the hook. A deformation hollow area is also provided on the back plate. The deformation hollow area is arranged at the root of the hook, so that on the one hand, the deformation of the hook depends on its own deformation, and on the other hand, due to the existence of the deformation hollow area, the back plate can also deform at the position where the hook is connected, avoiding the problem that the deformation of the back plate is insufficient due to the integral structure of the back plate, improving the deformation amount of the hook itself, resulting in too large a deformation difference between the back plate and the hook, and increasing the probability of hook fracture.

[0010] Preferably, a limiting part is provided on the button locking unit, and a docking part for connecting the limiting part is provided on the fitting groove. A limiting part is provided on the back plate, and a docking part is provided on the locking seat. Since the size of the back plate is smaller than that of the fitting groove, the locking seat and the button locking unit are accurately positioned by the snap connection between the docking part and the limiting part.

[0011] Preferably, the setting direction of the limiting part on the button locking unit is perpendicular to the flipping axis of the flipping plate. The setting directions of the limiting part and the docking part are perpendicular to the flipping axis of the flipping plate, ensuring the smoothness of the connection. During the connection process, only the vertical midlines of the locking seat and the button locking unit need to be aligned. Even if there is a certain deviation in the horizontal midline, the alignment of the limiting part and the docking part can be ensured, and the self-adaptive alignment adjustment can be guaranteed during the subsequent flipping process.

[0012] Preferably, the limiting part is a limiting protrusion, the docking part is a docking opening, and the docking opening is snap-connected to the limiting protrusion. The limiting part is a limiting protrusion. Compared with the docking opening, the strength of the limiting protrusion is lower. During the subsequent internal snap-limiting process, after the limiting protrusion is damaged, it is more flexible and less costly to replace the button locking unit.

[0013] Preferably, a fixing opening is provided on the button locking unit, an avoidance opening is provided on the locking seat, the setting position of the avoidance opening is aligned with the setting position of the fixing opening, and the size of the avoidance opening is larger than that of the fixing opening. A fixing opening is provided on the back plate, and a corresponding avoidance opening is also provided at the same position on the locking seat. The opening size of the avoidance opening is larger than that of the fixing opening, so that the connecting bolt can pass through the avoidance opening to abut against the fixing opening and lock the button locking unit on the back plate of the meter box. Therefore, it is not necessary to disassemble the button locking unit from the locking seat during the installation process of the button locking unit, so that the button locking unit and the locking seat can be connected together for factory assembly in advance, facilitating subsequent transportation and installation.

[0014] Preferably, an opening side plate is provided on one side of the button locking unit close to the locking seat. When the button locking unit is connected to the locking seat, the inner circle of the opening side plate is flush with the avoidance opening. A circumferential opening of the fixed opening is provided with an opening side plate. After the button locking unit and the locking seat are connected, the opening side plate is aligned with and abuts against the avoidance opening, playing a role in limiting and strengthening the connection strength of the fixed opening.

[0015] Preferably, the button locking unit includes a connecting back surface, and the locking seat includes an installation surface. When the button locking unit is connected to the locking seat, there is a gap between the installation surface and the connecting back surface. After the button locking unit is connected to the locking seat, there is still a certain gap between the installation surface and the connecting back surface, which can prevent the locking seat from hitting the watch box back plate first and ensure that the connection stroke between the locking seat and the button locking unit is sufficient.

[0016] The beneficial effects of the present utility model are as follows:

[0017] (1) It can reduce the materials required for production, while reducing the weight and facilitating subsequent transportation and assembly;

[0018] (2) Make full use of the space inside the fitting groove for snap connection, avoid interference with the watch box back plate, and ensure the connection strength;

[0019] (3) Integrate the easily worn parts on the button locking unit, improve the flexibility and cost of subsequent maintenance and replacement, and can also change the material of the button locking unit. On the basis of improving the connection strength, the production cost can be controlled to the greatest extent;

[0020] (4) Ensure the smooth deformation of the hook, reduce the degree of deformation of the hook itself, and thus reduce the risk of hook fracture;

[0021] (5) The opening size of the avoidance opening is larger than that of the fixed opening, so that the button locking unit and the locking seat can be connected together for factory assembly in the early stage, and then the bolt can be directly inserted through the avoidance opening to connect the fixed opening, improving the installation efficiency.

[0030] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] Embodiment 1:

[0032] As shown in Figure 1 , 2 , ,

[0033] , Figure 1 2 A button-type flip locking module for an electric energy meter connector includes a locking seat 1 provided on a flip plate of a connector. A button locking unit 2 is detachably connected to the locking seat 1. An engaging groove 11 is provided on the locking seat 1. The button locking unit 2 is connected to the locking seat 1 and is engaged in the engaging groove 11. The button locking unit 2 is connected to the back plate of the meter box, and the locking seat 1 flips synchronously with the flip plate. An engaging groove 11 is provided on the locking seat 1, and the engaging groove 11 is connected to the button locking unit 2. The opening area of the engaging groove 11 is larger than the area of the button locking unit 2. During use, since the engaging groove 11 can accommodate the button locking unit 2, the button locking unit 2 can be engaged inside the engaging groove 11 during installation, ensuring the stability of the connection. At the same time, it can leave space for thickening the dimensions of the other parts of the locking seat 1. Since the locking seat 1 is connected to the flip plate, the thickness of the flip plate can be made thicker, improving the structural strength. At the same time, since the button locking unit 2 is a unit module and is only connected to the back plate of the meter box, while ensuring the stability of the flip plate through the back plate of the meter box, there is no connection relationship with other components. The structure of the original base back plate 21 is simplified, facilitating production and assembly. The button locking unit 2 can be attached to the locking seat 1, that is, synchronously connected to the flip plate for factory shipment. Since the button locking unit 2 is only connected to the back plate of the meter box and is detachably connected to the locking seat 1 by clamping, the connection parts with the fixed base are reduced, saving production consumables. And it is convenient for subsequent maintenance and replacement. Only the damaged button locking unit 2 needs to be replaced, avoiding replacing large-size and complex-connection-relationship components such as the flip plate and the fixed bottom plate, with better flexibility.​​, as shown in FIGS. 3, the button locking unit 2 includes a back plate 21. On the side of the back plate 21 facing the locking seat 1, there is a hook 22, and on the locking seat, there is a groove 12 for snap-connecting the hook 22. The button locking unit 2 includes a back plate 21, and the back plate 21 is connected to the fitting groove 11 with a gap.

[0034] On the locking seat 1, there is a groove 12, and on the button locking unit 2, there is a hook 22. Through this setting, the connection position between the hook 22 and the groove 12 can be set inside the fitting groove 11, thus making full use of the internal space of the fitting groove 11. Therefore, it is avoided to set the connection position close to the back plate of the meter box, reducing the interference situation. During the connection process, the hook 22 on the button locking unit 2 needs to deform frequently. Relatively, the groove 12 on the locking seat 1 has a relatively small amount of deformation. The probability of deformation and breakage of the hook 22 is relatively large. Therefore, the hook 22 needs to be replaced and repaired frequently. Setting the hook 22 on the button locking unit 2 can reduce the subsequent maintenance cost. The button locking unit 2 can also be made of a high-strength material, including but not limited to metal, so as to improve the service life of the hook 22, ensure that the production cost is controllable, and be able to control the overall weight and production cost. The gap left between the back plate 21 and the fitting groove 11 can ensure the smoothness of the butt joint.

[0035] As Figure 1 , 2 shown, a deformation hollow area 23 is provided on the back plate 21, and the deformation hollow area 23 is arranged close to the root of the hook 22. There is also a deformation hollow area 23 on the back plate 21. The deformation hollow area 23 is arranged at the root of the hook 22, so that on the one hand, the deformation of the hook 22 depends on its own deformation, and on the other hand, due to the existence of the deformation hollow area 23, the back plate 21 can also deform at the position where the hook 22 is connected, avoiding the problem that the deformation of the back plate 21 is insufficient due to the whole back plate 21, increasing the amount of deformation of the hook 22 itself, and resulting in too large a deformation difference between the back plate 21 and the hook 22, leading to a large probability of breakage of the hook 22.

[0036] As Figure 1 , 2 shown in FIGS. 3, a limiting part 24 is provided on the button locking unit 2, and a docking part 13 for connecting the limiting part 24 is provided on the fitting groove 11. The setting direction of the limiting part 24 on the button locking unit 2 is perpendicular to the flipping axis of the flipping plate. The limiting part 24 is a limiting protrusion, and the docking part 13 is a docking opening, and the docking opening snap-connects the limiting protrusion.

[0037] A limiting portion 24 is provided on the back plate 21, and a docking portion 13 is provided on the locking seat 1. Since the size of the back plate 21 is smaller than the size of the fitting groove 11, the locking seat 1 and the button locking unit 2 are accurately positioned through the engagement connection between the docking portion 13 and the limiting portion 24. The setting directions of the limiting portion 24 and the docking portion 13 are perpendicular to the flipping axis of the flipping plate, ensuring the smoothness of the connection. During the connection process, only the vertical midlines of the locking seat 1 and the button locking unit 2 need to be aligned. Even if there is a certain deviation in the horizontal midline, it can ensure the alignment of the limiting portion 24 and the docking portion 13, and can ensure adaptive alignment adjustment during the subsequent flipping process. The limiting portion 24 is a limiting protrusion, which has a lower strength compared to the docking opening. During the subsequent internal engagement and limiting process, after the limiting protrusion is damaged, it is more flexible and less costly to replace the button locking unit 2.

[0038] As Figure 2 , 3 , as shown in Figure 4, a fixing opening 25 is provided on the button locking unit 2, and an avoidance opening 14 is provided on the locking seat 1. The setting position of the avoidance opening 14 is aligned with the setting position of the fixing opening 25, and the size of the avoidance opening 14 is larger than the size of the fixing opening. On the side of the button locking unit 2 close to the locking seat 1, there is an opening side plate 26. When the button locking unit 2 is connected to the locking seat 1, the inner circle of the opening side plate 26 is flush with the avoidance opening 14.

[0039] A fixing opening 25 is provided on the back plate 21, and a corresponding avoidance opening 14 is also provided at the same position on the locking seat 1. The opening size of the avoidance opening 14 is larger than the opening size of the fixing opening 25, so that the connecting bolt can pass through the avoidance opening 14 to abut against the fixing opening 25 and lock the button locking unit 2 on the back plate of the meter box. Therefore, it is not necessary to disassemble the button locking unit 2 from the locking seat 1 during the installation process of the button locking unit 2, enabling the button locking unit 2 and the locking seat 1 to be connected together for factory assembly in advance, which is convenient for subsequent transportation and installation. A circumferential opening side plate 26 is provided around the fixing opening 25. After the button locking unit 2 and the locking seat 1 are connected, the opening side plate 26 is aligned with and abuts against the avoidance opening 14, playing a role in limiting and strengthening the connection strength of the fixing opening 25.

[0040] As Figure 5 shown, the button locking unit 2 includes a connecting back surface 27, and the locking seat 1 includes an installation surface 15. When the button locking unit 2 is connected to the locking seat 1, there is a gap between the installation surface 15 and the connecting back surface 27. After the button locking unit 2 is connected to the locking seat 1, there is still a certain gap between the installation surface 15 and the connecting back surface 27, which can prevent the locking seat 1 from touching the back plate of the meter box first and ensure that the connection stroke between the locking seat 1 and the button locking unit 2 is sufficient.

[0041] In this embodiment, the assembly and working process of the button-type flipping locking module of the electricity meter connector are as follows: In this embodiment, it includes a locking seat 1 and a button locking unit 2. The locking seat 1 is connected to the flipping plate of the connector or integrally formed with the flipping plate. During the rotation process, the locking seat 1 rotates synchronously with the flipping plate, while the button locking unit 2 is fixed on the back panel of the meter box. The absolute position of the back panel of the meter box is fixed and unchanged. Therefore, during the flipping process of the connector, the flipping plate will drive the locking seat 1 to move relative to the button locking unit 2. The locking seat 1 is arranged on the upper part of the flipping plate, and the lower part of the flipping plate is connected to the fixed base. The fixed base is rotatably connected to the flipping plate, and the flipping plate rotates around the rotating shaft on the fixed base. At the same time, the fixed base is also connected to the back panel of the meter box. After the flipping plate is connected to the button locking unit 2 through the locking seat 1, both the upper and lower parts of the flipping plate are fixedly constrained relative to the back panel of the meter box, thereby ensuring the stability of the electricity meter connected to the connector.

[0042] In this embodiment, specifically, a fitting groove 11 is provided on the locking seat 1. The fitting groove 11 is a grooved structure, and the fitting groove 11 is connected to the back panel 21 on the button locking unit 2. The grooved area of the fitting groove 11 is larger than the area of the back panel 21 of the button locking unit 2. When the button locking unit 2 is connected to the locking seat 1, the fitting groove 11 completely covers and accommodates the back panel 21. During use, since the fitting groove 11 can accommodate the back panel 21 of the button locking unit 2, the button locking unit 2 can be fitted inside the fitting groove 11 during installation, ensuring the stability of the connection. At the same time, it can leave space for thickening the dimensions of the other parts of the locking seat 1. Since the locking seat 1 is connected to the flipping plate, the thickness of the flipping plate can be made thicker, improving the structural strength. At the same time, since the size of the back panel 21 is smaller than the size of the fitting groove 11, there is a relatively large gap between the back panel 21 and the fitting groove 11 during the connection process. Since the locking seat 1 is connected to the flipping plate and moves synchronously with the flipping plate, during the movement of the locking seat 1 towards the button locking unit 2, it is a rotational movement with a gradually decreasing included angle, rather than vertically buckling the locking seat 1 and the button locking unit 2. Therefore, the gap between the back panel 21 and the fitting groove 11 can ensure the smoothness of the butt joint.

[0043] Further, in this embodiment, a groove 12 is provided on the locking seat 1, where the groove 12 is of a snap-fit groove structure. A hook 22 is provided on the button locking unit 2, where the hook 22 is of a claw-shaped structure extending toward one side of the groove 12. Through this setting, the connection position between the hook 22 and the groove 12 can be set inside the fitting groove 11, thus making full use of the internal space of the fitting groove 11. Since the button locking unit 2 is connected to the meter box back plate, the connection position is avoided being set close to the meter box back plate, reducing interference. At the same time, during the connection process, the hook 22 (i.e., the claw-shaped structure) needs to deform to engage with the groove 12. Therefore, the hook 22 on the button locking unit 2 needs to deform frequently. In contrast, the groove 12 on the locking seat 1 has a relatively small amount of deformation. Relatively, the probability of deformation and breakage of the hook 22 is relatively high. Therefore, the hook 22 needs to be frequently replaced and repaired to ensure that the deformation elasticity of the hook 22 is sufficient and to avoid the insufficient clamping force of the hook 22 engaging with the groove 12 affecting the stability of the electricity meter. Therefore, setting the hook 22 on the button locking unit 2 can reduce the subsequent maintenance cost. Further, since the hook 22 requires strong structural strength, the button locking unit 2 can be made of a high-strength material such as metal, thereby increasing the service life of the hook 22. Since the overall size of the button locking unit 2 is smaller than that of the fitting groove 11, the production cost can be controlled. Compared with setting the locking seat 1 or the entire flip plate to a high-strength material, the overall weight and production cost can be controlled.

[0044] Further, in this embodiment, the hooks 22 are provided on both sides of the back plate 21, and at the upper and lower edges of both sides of the back plate 21. At the same time, a deformation hollowed-out area 23 is also provided on the back plate 21, where the deformation hollowed-out area 23 is provided at the root of the hook 22. Since the hook 22 is provided at the edge position of the back plate 21 and is connected to the deformation hollowed-out area 23, the deformation of the hook 22 depends on its own deformation on the one hand, and on the other hand, due to the existence of the deformation hollowed-out area 23, the back plate 21 can also deform at the position where the hook 22 is connected, avoiding the problem that the back plate 21 has insufficient deformation due to the whole back plate 21, increasing the amount of deformation of the hook 22 itself, and resulting in too large a deformation difference between the back plate 21 and the hook 22, leading to a high probability of breakage of the hook 22. In this embodiment, the deformation hollowed-out area 23 is of a waist-shaped groove structure, and the deformation hollowed-out area 23 is vertically arranged and perpendicular to the deformation direction of the hook 22.

[0045] Further, in this embodiment, a limiting portion 24 is provided on the back plate 21, and a docking portion 13 is provided on the locking seat 1. The limiting portion 24 is a limiting protrusion in this embodiment, and the docking portion 13 is a docking opening. Since the size of the back plate 21 is smaller than the size of the fitting groove 11, in this embodiment, the locking seat 1 and the button locking unit 2 are accurately positioned through the engagement connection between the docking portion 13 and the limiting portion 24. The setting directions of the limiting portion 24 and the docking portion 13 in this embodiment are vertically arranged, that is, perpendicular to the flipping axis of the flipping plate, and are provided on both the upper and lower sides. Thus, during the flipping process of the flipping plate, the lower docking portion 13 and the limiting portion 24 will come into contact first, and the upper docking portion 13 and the limiting portion 24 will come into contact last, ensuring the smoothness of the connection. At the same time, during the connection process, only the vertical midlines of the locking seat 1 and the button locking unit 2 need to be aligned. Even if there is a certain deviation in the horizontal midline, the alignment of the limiting portion 24 and the docking portion 13 can be ensured, and self-adaptive alignment adjustment can be ensured during the subsequent flipping process.

[0046] Further, in this embodiment, a fixing opening 25 is provided at the center position of the back plate 21. The fixing opening 25 is a waist-shaped hole structure, and the extending direction of the fixing opening 25 is vertically extended. A relief opening 14 is also provided at the same position on the locking seat 1. The opening size of the relief opening 14 is larger than the opening size of the fixing opening 25. At the same time, the horizontal size of the relief opening 14 is larger than the nut of the connecting bolt, and the horizontal size of the fixing opening 25 is larger than the screw rod of the connecting bolt and smaller than the nut of the connecting bolt, so that the connecting bolt can pass through the relief opening 14 to abut against the fixing opening 25 and lock the button locking unit 2 on the back plate of the meter box. Due to the existence of the relief opening 14, the connecting bolt can directly pass through the flipping plate to lock the button locking unit 2 on the back plate of the meter box. Therefore, it is not necessary to disassemble the button locking unit 2 from the locking seat 1 during the installation process of the button locking unit 2. Furthermore, the button locking unit 2 and the locking seat 1 can be connected together for factory assembly in the early stage, facilitating subsequent transportation and installation. Further, an opening side plate 26 is provided in a circumferential circle of the fixing opening 25. After the button locking unit 2 and the locking seat 1 are connected, the opening side plate 26 is aligned with and abuts against the relief opening 14, playing a role in limiting and strengthening the connection strength of the fixing opening 25. At the same time, during the process of connecting the locking seat 1 with the button locking unit 2, the impact force of the locking seat 1 on the hook 22 is reduced by the opening side plate 26 abutting against the edge position of the relief opening 14, and the connection depth between the locking seat 1 and the button locking unit 2 is limited, improving the connection stability.

[0047] Further, in this embodiment, after the button locking unit 2 is connected to the locking seat 1, there is still a certain gap between the mounting surface 15 and the connection back surface 27, and the two are not coplanar, so as to avoid the locking seat 1 hitting the back panel of the watch box first, resulting in ineffective engagement between the hook 22 and the groove 12, and ensuring that the connection stroke between the locking seat 1 and the button locking unit 2 is sufficient.
