Abstract
Description
Technical Field
[0001] This utility model relates to the field of low-voltage electrical appliances, specifically to an indicator structure for a surge protector. Background Technology
[0002] After a surge protector trips, although the protected lines and equipment can still operate normally, they lose their surge protection function. If the indicator does not provide an accurate status indication, maintenance personnel may not realize that the surge protector has failed. When a surge occurs again, it may affect the normal operation of the equipment or even cause damage, resulting in losses. Therefore, the indicator function of the surge protector is crucial.
[0003] Existing technologies have complex indicator structures, are difficult to assemble, and are unreliable. For example, in one existing technical solution, the indicator's movement mode is achieved by smoothly moving under the combined action of a push rod and a spring to switch the indicator state. The springs involved are small in size, making assembly difficult, time-consuming, and uneconomical. Utility Model Content
[0004] The purpose of this invention is to overcome at least one defect of the prior art and provide an indicator structure for a surge protector.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] The surge protector's indicator structure includes a housing, a protective element and a support installed inside the housing, an indicator rotatably mounted on the support, a push rod slidably mounted on the support, a conductive plate fixedly mounted on the push rod, and a drive member for driving the push rod. The conductive plate is fixed to the first electrode of the protective element by welding. The indicator includes an indicator part, a driven part, and a mating part. The push rod includes a pushing part. When the indicator is in a first position, the mating part is limited between the pushing part and the limiting surface of the support. After the conductive plate is released from the first electrode, the drive member drives the push rod to slide, causing the pushing part to separate from the mating part and push against the driven part to drive the indicator to a second position.
[0007] Optionally, the mating part and the driven part of the indicator are arranged at an angle. When the indicator is in the first position, the mating part is parallel to the movement direction of the push rod, the driven part is arranged at an angle to the movement direction of the push rod, and is located on the movement path of the pushing part.
[0008] Optionally, the limiting surface is parallel to the movement direction of the push rod. When the indicator is in the first position, the pushing part pushes the mating part to fit against the limiting surface, while the driven part is set at an angle to the limiting surface. When the indicator is in the second position, the pushing part pushes the driven part to fit against the limiting surface, while the mating part is set at an angle to the limiting surface.
[0009] Optionally, the driven part and the mating part are bent and connected, and two indicator shafts are provided on both sides at the connection between the driven part and the mating part. The limiting surface of the support member is provided with two limiting bosses that are spaced apart and opposite to each other along the axial direction of the indicator shafts. A limiting groove is formed between the two limiting bosses. The limiting bosses are provided with a rotating groove that mates with the indicator shafts.
[0010] Optionally, the indicator is slidably disposed between the sliding surface of the support member and a wall of the housing. The indicator and the driven part are arranged at an angle and are movably connected, so that when the pushing part pushes against the driven part, the driven part can drive the indicator to slide along the sliding surface.
[0011] Optionally, the direction of motion of the push rod is perpendicular to the direction of motion of the driven part.
[0012] Optionally, the driven part and the indicating part are integrally connected, and at least one end of the driven part connected to the indicating part is an elastic structure, so that the end of the driven part connected to the indicating part can deform.
[0013] Optionally, the end of the driven part connected to the indicating part is provided with a thin-walled feature, the thickness of which is less than the thickness of the rest of the driven part.
[0014] Optionally, the driven part and the indicating part are separately disposed, and the driven part is hinged to the indicating part via a hinge shaft.
[0015] Optionally, the driven part is integrally connected to the hinge shaft, and the two ends of the hinge shaft protrude from both sides of the driven part. The indicator part is integrally provided with two hinge arms spaced apart from each other, and the hinge arms have hinge grooves that cooperate with the hinge shaft.
[0016] Optionally, the mating part and the driven part are arranged at an angle, the indicating part and the driven part are arranged at an angle, the indicating part, the driven part and the mating part are integrally formed, and the indicating part and the mating part are respectively located on both sides of the plane where the driven part is located.
[0017] Optionally, the support member is a U-shaped shell structure that partially encloses the protective element. The bottom outer side of the support member is provided with diagonally distributed sliding grooves and the limiting surface. The push rod includes a push rod body slidably disposed in the sliding groove and an extension portion extending out of the sliding groove and arranged parallel to the indicator. The extension portion extends toward the indicator and is provided with the pushing portion. The first electrode of the protective element passes through the bottom edge of the support member and protrudes from the limiting surface. One end of the conductive sheet is arranged parallel to the push rod body in the sliding groove, and the other end of the conductive sheet extends out of the sliding groove and is welded to the first electrode. The outer side of one side of the support member is a sliding surface that is spaced apart from a wall of the outer shell and slidably engaged with the indicator portion of the indicator. The wall of the outer shell is provided with an indicator window corresponding to the indicator portion.
[0018] Optionally, the driving component is a tension spring, and its two ends are connected to a support component and a push rod, respectively.
[0019] The surge protector of this utility model has an indicator structure in which a sliding push rod pushes the indicator element to switch between the driven part and the mating part, causing the indicator element to rotate and switch positions to complete the switching of the indicator state. This eliminates the need for a separate spring to drive the indicator element to switch positions, reducing the number of parts, saving costs, simplifying the structure, facilitating assembly, and ensuring reliable indicator function.
[0020] Furthermore, the two parts of the indicator that mate with the pusher of the push rod are set at an included angle, resulting in a simple structure and smooth driving process. By having the pusher push different parts of the indicator to fit against the limiting surface, the indicator can stably and reliably stay in different positions, improving the reliability of the indicator function.
[0021] In addition, the indicator has a simple structure, is easy to form, and can rotate stably without deviation in the direction of the rotation axis. The indicator position switching is accurate, thereby improving the accuracy of the indication. Attached Figure Description

Detailed Implementation
[0038] The following embodiments, in conjunction with the accompanying drawings, further illustrate specific implementations of the indicating structure of the surge protector of this utility model. The indicating structure of the surge protector of this utility model is not limited to the descriptions in the following embodiments.
[0039] like Figure 1 and Figure 2 As shown, the surge protector's indicator structure in this embodiment includes a housing 1, a protective element 2 and a support 3 installed within the housing 1, an indicator 4 rotatably mounted on the support 3, a push rod 5 slidably mounted on the support 3, a conductive sheet 7 fixedly mounted on the push rod 5, and a drive member 6 for driving the push rod 5. The conductive sheet 7 is fixed to the first electrode 21 of the protective element 2 by welding. The indicator 4 includes an indicator portion 41, a driven portion 42, and a mating portion 43. The push rod 5 includes a pushing portion 51. The indicator 4 can move between a first position and a second position to indicate the state of the surge protector, such as... Figure 1 and Figure 2As shown, when the surge protector is in its normal state and the indicator 4 is in the first position, the mating part 43 is limited between the pushing part 51 and the limiting surface 31 of the support 3; as Figure 4 and Figure 5 As shown, after the conductive sheet 7 is released from the first electrode 21, the surge protector enters the tripped state. The driving member 6 drives the push rod 5 to slide, causing the pushing part 51 to separate from the cooperating part 43, and pushes against the driven part 42 to drive the indicator 4 to move to the second position.
[0040] It should be noted that the protection element 2 is a varistor, gas discharge tube, or transient suppression diode. The protection element 2 has a first electrode 21 and a second electrode (not shown in the figure). The first electrode 21 is soldered to the conductive sheet 7 using low-temperature alloy solder paste. The conductive sheet 7 is electrically connected to the first contact piece 8 via a flexible connector 81. The two ends of the flexible connector 81 are soldered to the conductive sheet 7 and the first contact piece 8, respectively. The second electrode is electrically connected to the second contact piece 9 via soldering or other methods. The first contact piece 8 and the second contact piece 9 are used for external connection, serving as the output and input terminals of the surge protector, respectively. Figure 4 and Figure 5 As shown, when the temperature of the protection element 2 rises after deterioration or overload, reaching the temperature at which the low-temperature alloy solder melts, the low-temperature alloy solder between the first electrode 21 and the conductive sheet 7 melts. At this time, the push rod 5 moves rapidly upward under the action of the driving component 6, causing the conductive sheet 7 and the first electrode 21 to separate, thereby cutting off the circuit current, preventing the surge protector from catching fire, and protecting the safety of the line and equipment. This part is the prior art in this field.
[0041] In this embodiment of the surge protector's indicator structure, the sliding push rod 5 pushes the indicator 4 through the pushing part 51 to switch between the driven part 42 and the mating part 43, causing the indicator 4 to rotate and switch positions to complete the indicator state switching. There is no need to set up a separate spring for driving the indicator 4 to switch positions, which reduces the number of parts, saves costs, simplifies the structure, facilitates assembly, and ensures reliable indicator function.
[0042] like Figure 1 and Figure 2 As shown, the mating part 43 and the driven part 42 of the indicator 4 are arranged at an angle. When the indicator 4 is in the first position, the mating part 43 is parallel to the movement direction of the push rod 5, and the driven part 42 is arranged at an angle to the movement direction of the push rod 5 and is located on the movement path of the pushing part 51. The two parts of the indicator 4 that mate with the pushing part 51 of the push rod 5 are arranged at an angle, resulting in a simple structure and smooth driving process. Furthermore, the limiting surface 31 is parallel to the movement direction of the push rod 5, as shown in the figure. Figure 1 and Figure 2 As shown, when the indicator 4 is in the first position, the pushing part 51 pushes against the mating part 43 and fits against the limiting surface 31, while the driven part 42 is set at an angle to the limiting surface 31; Figure 4 and Figure 5 As shown, when the indicator 4 is in the second position, the pushing part 51 pushes the driven part 42 to fit against the limiting surface 31, while the mating part 43 is set at an angle to the limiting surface 31. By pushing different parts of the indicator 4 against the limiting surface 31 by the pushing part 51, the indicator 4 can be stably and reliably stopped in different positions, improving the reliability of the indicator function.
[0043] For example, the driven part 42 of the indicator 4 is bent and connected to the mating part 43. Two indicator shafts 44 extend to both sides from the connection point of the driven part 42 and the mating part 43. Two limiting bosses 32 are provided on the limiting surface 31 of the support member 3, spaced apart axially from each other along the indicator shafts 44. A limiting groove is formed between the two limiting bosses 32. Each limiting boss 32 has a rotating groove 33 that mates with the indicator shafts 44. The connection point of the driven part 42 and the mating part 43 is engaged within the limiting groove, meaning the indicator 4 can rotate around the indicator shafts 44 but will not deviate axially along the indicator shafts 44. The two indicator shafts 44 are rotatably installed within the rotating grooves 33 of the two limiting bosses 32. The indicator 4 has a simple structure, is easy to form, and can rotate stably without deviation in the direction of the rotation axis. The position switching of the indicator 4 is accurate, thereby improving the accuracy of the indication.
[0044] Of course, as other embodiments, the indicator 4 may be provided with only one indicator shaft 44; or the indicator shaft 44 may be a separate round shaft, and the connection between the driven part 42 and the mating part 43 may be provided with a round hole that mates with the indicator shaft 44.
[0045] like Figures 1-7 The indicator 4 shown is an embodiment one or as shown below. Figures 8-15 In the second embodiment of the indicator 4 shown, the indicator part 41 of the indicator 4 is slidably disposed between the sliding surface 34 of the support 3 and a wall of the outer casing 1. The indicator part 41 and the driven part 42 are arranged at an angle, and the indicator part 41 and the driven part 42 are movably connected, so that when the pushing part 51 pushes against the driven part 42, the driven part 42 can drive the indicator part 41 to slide along the sliding surface 34. By making the connection between the driven part 42 and the indicator part 41 of the indicator 4 movable, the swinging driven part 42 drives the indicator part 41 to translate, making the position of the indicator part 41 more controllable and the indication more accurate and stable.
[0046] The indicator part 41 and the driven part 42 of the indicator 4 are movably connected in various embodiments, such as... Figure 7 In the first embodiment of the indicator 4 shown, the driven part 42 of the indicator 4 is integrally connected with the indicator part 41. At least one end of the driven part 42 connected to the indicator part 41 is an elastic structure, so that the end of the driven part 42 connected to the indicator part 41 can be deformed.
[0047] For example, one end of the driven part 42 connected to the indicating part 41 is provided with a thin-walled feature 421, the thickness of which is less than the thickness of the rest of the driven part 42. The indicating element 4 is preferably made of a soft and tough material (e.g., POM or similar materials). The bending connection between the driven part 42 and the indicating part 41 uses a thin-walled structure to achieve a deformation function. The structure is simple and easy to construct and form, allowing the swinging driven part 42 to drive the indicating part 41 to translate.
[0048] like Figure 14 and Figure 15 In the second embodiment of the indicator 4 shown, the driven part 42 and the indicator part 41 of the indicator 4 are separately provided, and the driven part 42 is hinged to the indicator part 41 through the hinge shaft 45.
[0049] For example, the driven part 42 is integrally connected to the hinge shaft 45, with both ends of the hinge shaft 45 protruding from both sides of the driven part 42. The indicating part 41 is integrally provided with two spaced-apart opposing hinge arms 46. The hinge arms 46 are similar to the head structure of an open-end wrench and have hinge grooves 47 that mate with the hinge shaft 45. Both ends of the hinge shaft 45 are rotatably installed in the hinge grooves 47 of the two hinge arms 46. The driven part 42 and the indicating part 41 are movably connected by hinges of the hinge shaft 45 and the hinge arms 46, resulting in uniform structural strength and a more stable and reliable movable connection. Of course, as another embodiment, only one hinge arm 46 can be provided, hinged to the hinge shaft 45 to achieve the hinge connection between the driven part 42 and the indicating part 41; alternatively, the hinge shaft 45 can be a single round shaft, with both the driven part 42 and the indicating part 41 having round holes that mate with the hinge shaft 45. Furthermore, the indicating part 41 and the mating part 43 are located on opposite sides of the plane where the driven part 42 is located. Both the driven part 42 and the mating part 43 of the indicating element 4 are preferably straight-plate structures, and the indicating part 41 is preferably a straight-plate structure or an L-shaped straight-plate structure. The end of the indicating part 41 furthest from the driven part 42 serves as the indicating point. For example, the entire indicating element 4 or the end of the indicating part 41 furthest from the driven part 42 can be painted green as an indicator of the normal state of the surge protector, and the sliding surface 34 of the support member 3 can be painted red as an indicator of the tripped state of the surge protector. Of course, the indicating mark can also be other colors, text, symbols, patterns, or combinations of colors, text, symbols, and patterns.
[0050] Furthermore, the movement direction of the push rod 5 is perpendicular to the movement direction of the driven part 42, that is, the sliding surface 34 is perpendicular to the movement direction of the driven part 42, and the sliding surface 34 is also perpendicularly connected to the limiting surface 31. When the indicator 4 is in the first position, the indicator part 41 and the driven part 42 of the indicator 4 form a "7" shape, that is, the included angle between the indicator part 41 and the driven part 42 is an acute angle; when the indicator 4 is in the second position, the indicator part 41 and the driven part 42 of the indicator 4 form an L-shaped structure, that is, the included angle between the indicator part 41 and the driven part 42 is a right angle. It is easy to construct and form, and the overall layout is compact, which is conducive to the miniaturization design of surge protectors.
[0051] Of course, as a third embodiment (not shown in the figure), the indicator 41 and the driven part 42 are arranged at an angle, the driven part 42 and the indicator 41 are fixedly connected and not easily deformed, the driven part 42 drives the indicator 41 to rotate to indicate the status of the surge protector, so space needs to be reserved for the rotation of the indicator 41. For example, the mating part 43 and the driven part 42 are arranged at an angle, the indicator 41 and the driven part 42 are arranged at an angle, the indicator 41, the driven part 42 and the mating part 43 are integrally formed, and the indicator 41 and the mating part 43 are respectively located on both sides of the plane where the driven part 42 is located.
[0052] like Figures 1-3 As shown, in a preferred embodiment of the overall structure of the surge protector, the support member 3 is a U-shaped shell structure that partially encloses the protective element 2, and the bottom edge of the support member 3 (i.e., Figure 1 The left side of the support member 3 is provided with diagonally distributed sliding grooves 35 and limiting surfaces 31. The push rod 5 includes a push rod body 52 slidably disposed in the sliding groove 35 and an extension part 53 extending out of the sliding groove 35 and arranged parallel to the indicator 4. The extension part 53 extends toward the indicator 4 and is provided with the pushing part 51. The first electrode 21 of the protective element 2 penetrates the bottom edge of the support member 3 and protrudes from the limiting surface 31, and is located below the indicator 4. One end of the conductive sheet 7 is arranged parallel to the push rod body 52 in the sliding groove 35, and the other end of the conductive sheet 7 extends out of the sliding groove 35 and is welded to the first electrode 21. One side of the support member 3 (i.e. Figure 1 The outer side of the upper side of the middle support member 3 is a wall of the outer shell 1 (i.e. Figure 2 The upper wall of the outer casing 1 has a sliding surface 34 that is spaced apart from each other and slides in cooperation with the indicator part 41 of the indicator 4. An indicator window 11 corresponding to the indicator part 41 is provided on one wall of the outer casing 1.
[0053] The driving component 6 can be configured in various ways. One possible configuration is that the driving component 6 is a tension spring, and its two ends are connected to the support component 3 and the push rod 5, respectively.
[0054] In this embodiment, a hook 36 is provided at the connection point between the bottom outer side of the support member 3 and one side of the support member 3. A hanging hole 531 is provided on the protruding part 53 of the push rod 5. The cooperating part 43 and the driven part 42 of the driving member 6 and the indicator member 4 are arranged side by side and located above the push rod body 52. One end of the driving member 6 is hung on the hook 36 of the support member 3, and the other end is hung in the hanging hole 531 of the push rod 5. One end of the first contact piece 8 connected to the flexible connection 81 is installed on the bottom outer side of the support member 3 and is diagonally distributed with the driving member 6. The other end of the first contact piece 8 protrudes from the support member 3 for external connection.
[0055] The specific operation process of the surge protector in this embodiment is as follows: Figure 1 and Figure 2 As shown, when the surge protector is in its normal state, i.e., when the indicator 4 is in the first position, the drive member 6 is in a stretched and energy-storing state. The pushing part 51 of the push rod 5 pushes the mating part 43 of the indicator 4 against the limiting surface 31, so that the driven part 42 is set at an angle to the limiting surface 31. At this time, the indicator window 11 of the housing 1 is opposite to the end of the indicator 41 away from the driven part 42, so that the indicator window 11 displays green, indicating that the surge protector is in its normal state; Figure 4 and Figure 5 As shown, when the surge protector trips, after the conductive sheet 7 is released from the first electrode 21, the driving member 6 releases energy to drive the push rod 5 to slide upward, causing the pushing part 51 of the push rod 5 to slide from the mating part 43 of the indicator 4 to the driven part 42. Thus, the pushing part 51 pushes against the driven part 42, causing the indicator 4 to move to the second position, that is, the pushing part 51 pushes the driven part 42 of the indicator 4 to fit against the limiting surface 31. The mating part 43 is set at an angle to the limiting surface 31. The indicator part 41 slides to the right, so that the end of the indicator part 41 away from the driven part 42 is offset from the indicator window 11, so that the indicator window 11 displays red, indicating that the surge protector is in a fault state.
[0056] Of course, as in other embodiments, the drive element 6 can also be a compression spring, torsion spring, or leaf spring. When the surge protector is in normal condition, the pushing part 51 of the push rod 5 pushes against the driven part 42 of the indicator 4; when the surge protector trips, as the push rod 5 moves down or away from the position of the indicator 4, the indicator 4 shifts, causing the structure and scheme of the change in the indication state caused by this scheme are also within the scope of protection of this scheme.
