Description

Technical Field

[0001] This application relates to the technical field of junction boxes, and more particularly to an anti-electric shock structure for a junction box. Background Technology

[0002] In numerous electrical equipment applications, junction boxes play an indispensable role as crucial electrical connection components. However, many junction boxes currently on the market have significant design deficiencies, particularly the lack of necessary anti-electric shock structures for their positive and negative terminals. This defect poses a significant safety hazard during actual operation. If an operator makes a mistake due to negligence or other unforeseen circumstances, both positive and negative terminals could potentially come into contact simultaneously. In such a situation, a short circuit would instantly occur, and the powerful current surge would severely damage internal components, rendering the equipment inoperable. Utility Model Content

[0003] The purpose of this application is to provide an anti-electric shock structure for a junction box to solve the problems of the prior art.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] On one hand, an anti-electric shock structure for a junction box is provided, applied to a junction box, wherein the junction box is provided with a positive connection terminal and a negative connection terminal at intervals. The anti-electric shock structure includes: a bracket and a protective plate slidably disposed on the bracket. The protective plate is capable of reciprocating between a first position and a second position. When the protective plate is in the first position, the protective plate blocks the positive connection terminal. When the protective plate is in the second position, the protective plate blocks the negative connection terminal. The bracket is provided with a boss, and the protective plate is provided with a protrusion on one side opposite to the boss. During the movement of the protective plate, the protrusion can strike the boss and produce a popping sound.

[0006] Furthermore, the bracket includes two spaced-apart support rods and a connecting plate connecting the two support rods, the protective plate is slidably connected between the two support rods, and the boss is disposed in the middle of the connecting plate.

[0007] Furthermore, the support rod is provided with insertion holes, and the protective plate includes a plate body and insertion shafts integrally formed on both sides of the plate body. The insertion shafts are inserted into the insertion holes, and the protrusions protrude from the plate body.

[0008] Furthermore, the diameter of the insertion shaft is greater than the thickness of the plate, and a through groove is provided on the opposite side of the insertion hole on the two support rods. The ratio of the thickness of the plate to the width of the through groove is less than 1 and greater than 0.9.

[0009] Furthermore, the connecting plate has protruding ribs at both ends along the moving direction of the protective plate, and the protruding ribs have limiting grooves for the protrusions to pass through.

[0010] Furthermore, a handle rib is provided on the side of the protective plate opposite to the convex bulge.

[0011] Furthermore, the bracket is provided with a positioning post, which is used for positioning and connecting the junction box body.

[0012] Furthermore, the positioning post is provided with a threaded hole.

[0013] Furthermore, the convex bulge includes a first convex bulge and a second convex bulge spaced apart along the moving direction of the protective plate. When the protective plate moves from the first position to the second position, the first convex bulge strikes the boss, making a popping sound and passing over the boss. When the protective plate moves from the second position to the first position, the second convex bulge strikes the boss, making a popping sound and passing over the boss.

[0014] Furthermore, the support rod has multiple reinforcing ribs on the side opposite to the connecting plate.

[0015] The beneficial effects of this application are as follows: The anti-electric shock structure is simple and practical in design. The sliding protective plate alternately shields the positive and negative terminals, effectively preventing simultaneous short circuits caused by operational errors and greatly improving the safety of the junction box. The engagement of the boss and the bulge produces a clicking sound, providing clear feedback to the operator, further reducing the probability of misoperation, effectively protecting the normal operation of the equipment, and avoiding equipment damage and fire hazards caused by short circuits.

[0022] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0025] like Figures 1 to 4As shown, this embodiment provides an anti-electric shock structure for a junction box, applied to a junction box. The junction box is provided with a positive connection terminal and a negative connection terminal at intervals. The anti-electric shock structure includes: a bracket 1 and a protective plate 2 slidably disposed on the bracket 1. The protective plate 2 can reciprocate between a first position and a second position. When the protective plate 2 is in the first position, the protective plate 2 blocks the positive connection terminal. When the protective plate 2 is in the second position, the protective plate 2 blocks the negative connection terminal. The bracket 1 is provided with a boss 103, and the protective plate 2 is provided with a protrusion 201 on one side opposite to the boss 103. During the movement of the protective plate 2, the protrusion 201 can hit the boss 103 and make a popping sound.

[0026] Based on the above scheme, a bracket 1 is installed on the junction box, and a protective plate 2 is slidably mounted on the bracket 1. When it is necessary to connect the positive or negative terminal, the protective plate 2 is slid to the corresponding position. In the first position, the protective plate 2 blocks the positive connection terminal, while the negative connection terminal is in a connectable state. The positive terminal is blocked, preventing it from contacting other conductive objects. When the protective plate 2 is in the second position, it blocks the negative connection terminal, while the positive connection terminal is still in a connectable state. The negative terminal is also blocked, preventing it from contacting other conductive objects. In this way, it is ensured that the positive and negative connection terminals are not exposed at the same time during operation, thus effectively preventing short circuits caused by simultaneous contact of the positive and negative terminals. At the same time, the boss 103 on the bracket 1 cooperates with the protrusion 201 on the protective plate 2. When the protective plate 2 moves, the protrusion 201 hits the boss 103, making a popping sound to remind the operator of the position status of the protective plate 2, further reducing the risk of simultaneous contact of the positive and negative terminals due to misoperation, and providing more reliable safety protection for the equipment.

[0027] In summary, this anti-electric shock structure is ingeniously designed and highly practical. The sliding protective plate 2 alternately shields the positive and negative terminals, fundamentally solving the problem of simultaneous exposure and easy contact of the positive and negative terminals in existing junction boxes, greatly improving the safety of junction box use. The spring-loaded feedback mechanism generated by the cooperation of the boss 103 and the boss 201 effectively alerts the operator, further preventing short-circuit faults caused by misoperation. This design effectively protects the normal operation of the equipment, avoiding equipment damage and potential fires caused by short circuits between the positive and negative terminals. It has significant safety benefits and practical value and can be widely applied to various junction box devices.

[0028] Furthermore, the bracket 1 includes two spaced-apart support rods 101 and a connecting plate 102 connecting the two support rods 101. The protective plate 2 is slidably connected between the two support rods 101, and the boss 103 is located in the middle of the connecting plate 102. When the protective plate 2 slides on the support rods 101, its movement trajectory is limited by the support rods 101, ensuring that the protective plate 2 moves stably and smoothly between the first and second positions, achieving alternating shielding of the positive and negative connection terminals. When the protective plate 2 slides to the position corresponding to the boss 103, the boss 201 strikes the boss 103, making a popping sound, clearly indicating that the protective plate 2 is in a critical position, reminding the operator that the positive or negative connection terminal has been shielded, effectively preventing the risk of simultaneous contact between the positive and negative terminals. This structural design ensures the reliable implementation of the anti-electric shock function by limiting the movement path of the protective plate 2 and setting position indicators.

[0029] Furthermore, the support rod 101 is provided with a socket 1011, and the protective plate 2 includes a plate body 202 and a shaft 203 integrally formed on both sides of the plate body 202. The shaft 203 is inserted into the socket 1011, and the protrusion 201 protrudes from the plate body 202. The cooperation between the shaft 203 and the socket 1011 ensures the smoothness and accuracy of the sliding of the protective plate 2, enabling the protective plate 2 to accurately switch the shielding position between the positive and negative connection ends. In addition, the protrusion 201 is provided on the plate body 202 and cooperates with the boss 103 on the bracket 1, providing clear operational feedback and effectively avoiding the problem of simultaneous contact of positive and negative terminals due to uncertain position. This design not only improves operational safety but also extends the service life of the anti-electric shock structure, reduces the equipment failure rate, and further enhances the safety and stability of the junction box.

[0030] The diameter of the insert shaft 203 is greater than the thickness of the plate 202. A through groove 1012 is provided on one side of the insertion holes 1011 on the two support rods 101. The ratio of the thickness of the plate 202 to the width of the through groove 1012 is less than 1 and greater than 0.9. Since the protective plate 2 is positioned between the two support rods 101, and the insert shaft 203 is inserted into the insertion hole 1011 with a clearance fit to ensure smooth sliding, and since part of the plate 202 is located within the through groove 1012, the thickness of the plate 202 needs to be slightly less than the width of the through groove 1012. This ensures that the thickness of the plate 202 does not impede movement during movement.

[0031] In some embodiments, the connecting plate 102 has protruding ribs 1021 at both ends along the moving direction of the protective plate 2, and the protruding ribs 1021 have limiting grooves 1022 for the protrusions 201 to pass through. When the protective plate 2 slides, the protrusions 201 on the plate 202 pass through the limiting grooves 1022 in sequence. The protruding ribs 1021 guide and limit the movement of the protective plate 2, ensuring that it slides smoothly along a predetermined trajectory. When the protrusions 201 pass through the limiting grooves 1022, the cooperation between the protruding ribs 1021 and the protrusions 201 further restricts the offset of the protective plate 2 and improves the stability of the sliding.

[0032] Preferably, a handle rib 204 is provided on the side of the protective plate 2 opposite to the protrusion 201. When the operator needs to move the protective plate 2, he / she can directly grasp the handle rib 204 to apply force, causing the protective plate 2 to slide on the bracket 1, which is convenient for the operator to apply force. Moreover, the position of the handle rib 204 ensures that the operator's fingers will not come into contact with the positive and negative terminals when moving the protective plate 2, further improving the safety of operation.

[0033] Generally, the bracket 1 is equipped with a positioning post 104, which is used for positioning and connecting the junction box. During actual installation, the positioning post 104 of the bracket 1 is inserted into the corresponding hole in the junction box body, allowing the bracket 1 to be stably fixed to the junction box. This design ensures a firm and reliable connection between the bracket 1 and the junction box, providing a stable support foundation for the subsequent sliding operation of the protection plate 2.

[0034] Meanwhile, the positioning post 104 is provided with a threaded hole. During installation, the positioning post 104 of the bracket 1 is aligned with the hole on the junction box body and inserted. Then, the bracket 1 is firmly fixed to the junction box by the cooperation of the bolt and the threaded hole, ensuring that the connection between the bracket 1 and the junction box is not only accurate but also firm and reliable.

[0035] Optionally, the protrusion 201 includes a first protrusion 201 and a second protrusion 201 spaced apart along the moving direction of the protective plate 2. When the protective plate 2 moves from the first position to the second position, the first protrusion 201 strikes the boss 103, making a popping sound, and then passes over the boss 103. When the protective plate 2 moves from the second position to the first position, the second protrusion 201 strikes the boss 103, making a popping sound, and then passes over the boss 103. When the protective plate 2 moves from the first position to the second position, the first protrusion 201 first approaches and strikes the boss 103, making a popping sound, and then passes over the boss 103. At this time, the protective plate 2 continues to slide to the second position, completing the blocking of the negative terminal. Conversely, when the protective plate 2 moves from the second position to the first position, the second protrusion 201 first strikes the boss 103 and makes a popping sound, and after passing over the boss 103, the protective plate 2 continues to move to the first position, completing the blocking of the positive terminal. This design ensures that during a single complete movement of the protection plate 2, whether in the forward or reverse direction, a popping sound is emitted by the impact of the protrusion 201 and the protrusion 103, reminding the operator that the protection plate 2 has reached a critical position, effectively preventing the risk of simultaneous contact between the positive and negative electrodes.

[0036] In some embodiments, the support rod 101 has a plurality of reinforcing ribs 1013 on the side opposite to the connecting plate 102. When the protective plate 2 slides on the support rod 101, the reinforcing ribs 1013 enhance the structural strength of the support rod 101, preventing deformation of the support rod 101 due to external forces, thereby ensuring the smoothness and accuracy of the sliding of the protective plate 2. The arrangement of the reinforcing ribs 1013 ensures that the support rod 101 remains stable under the sliding friction of the protective plate 2 and the external forces applied by the operator, without bending or twisting. This design ensures that the protective plate 2 can reliably switch between the first and second positions during long-term use, effectively preventing the risk of simultaneous contact between the positive and negative electrodes.
