Description

Technical Field

[0001] This invention relates to the field of electrical protection technology, and in particular to a remote signaling switch structure and a 1U surge protector. Background Technology

[0002] Currently, surge protectors require the addition of a remote signaling trigger structure. This structure is triggered when the electrical connection between the module and the base fails, and a remote signaling signal is provided to an external terminal device via a wireless transmission module. This allows the terminal device to monitor the surge protector and perform fault diagnosis and maintenance.

[0003] Please refer to Figure 1 and Figure 2 The surge protector in the prior art uses a remote signaling triggering method. The module is equipped with a conductive spring, a remote signaling spring, a tension spring, and a sliding plate. The contact end of the conductive spring is positioned opposite one of the electrodes of the resistor. The remote signaling spring has a first remote signaling pin and a second remote signaling pin. The first remote signaling pin is always in contact with the tension spring. Under normal conditions, the sliding plate moves below the conductive spring, and the contact end of the conductive spring is welded to one of the electrodes of the resistor, restricting the movement of the sliding plate. At this time, one end of the tension spring is fixed to the sliding plate and stretched to contact and electrically connect with the second remote signaling pin, forming a remote signaling path. When the solder joint between the conductive spring and the resistor electrode fails due to surge melting, the sliding plate is no longer restricted by the contact end of the conductive spring and returns to its initial position under the action of the tension spring. The tension spring returns to its unstretched state and disconnects from the second remote signaling pin, thus breaking the remote signaling path. This allows the signal to be transmitted to the wireless transmission module through the remote signaling spring, emitting a remote signal.

[0004] It is evident that the existing remote signaling triggering methods are relatively complex and require the use of multiple springs and tension springs, resulting in high costs. Summary of the Invention

[0014] Furthermore, the other end of the swing arm is provided with a protrusion, and the sliding assembly includes a slider and a spring;

[0015] The slider is provided with a second abutting arm and a receiving cavity located on the back of the second abutting arm. The second abutting arm abuts against the other end of the solder layer and the electrode spring.

[0016] The outer end face of the receiving cavity abuts against the side wall of the bracket. A column parallel to the second abutting arm is provided inside the receiving cavity. The spring is sleeved on the column. One end of the spring abuts against the inner end face of the receiving cavity, and the other end of the spring abuts against the side wall of the bracket.

[0019] Furthermore, the first housing is provided with a warning window, the slider includes a main body, a panel and a support column, the panel is spaced apart from the main body and the panel is positioned directly opposite the warning window, the support column is respectively connected to the main body and the panel, and the second abutment arm, the receiving cavity and the groove are all provided on the main body.

[0020] Furthermore, the bracket is provided with a first guide wall and a second guide wall that are parallel to each other in its width direction. The first guide wall is disposed between the main body of the slider and the surge protection element, and the second guide wall is disposed between the panel on the slider and the main body.

[0021] Furthermore, the protrusion is U-shaped, and the bottom surface of the groove is also U-shaped. The projected area of ​​the protrusion on the plane containing the bottom surface of the groove is smaller than the bottom surface area of ​​the groove.

When the solder layer between the electrode spring and the surge protection device melts due to a surge, the sliding assembly, no longer obstructed by the solder layer, begins to slide, causing the swing rod to swing. This causes the first abutting arm on the swing rod to disengage from the push-button switch, thereby changing the state of the push-button switch and sending a remote signal. The remote signaling switch structure of this application uses a push-button switch, which offers high reliability, a small product size, a compact structure, fewer required parts, and lower cost.

Detailed Implementation

[0046] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0047] Please refer to Figures 3 to 15 This embodiment provides a remote signaling switch structure, including a bracket 100, a push-button switch 200, a surge protection element 300, a swing rod 600, a sliding assembly, and an electrode spring 400.

[0048] Please refer to Figures 3 to 5The bracket 100 has a window 110 connecting its interior and exterior, and a pivot 120 located at the window 110. A push-button switch 200 is located outside the bracket 100 and directly opposite the window 110; the push-button switch 200 is used to trigger a remote signaling signal. A surge protection element 300 is mounted on the bracket 100 and has a first pin 310 and a second pin 320 diagonally distributed, with the first pin 310 located on the side of the bracket 100 away from the window 110. One end of the electrode spring 400 is disposed on the side of the bracket 100 near the window 110, and the other end of the electrode spring 400 is disposed on the side of the bracket 100 away from the window 110. The other end of the electrode spring 400 is stacked with the first pin 310 and welded to form a solder layer 500. Here, the stacking arrangement means that both the electrode spring 400 and the first pin 310 are provided with a soldering plane for welding, and the two soldering planes are overlapped in the vertical direction. For example, the two soldering planes can abut against each other or have a gap, which is not limited here. One end of the swing rod 600 is rotatably connected to the rotating shaft 120, and one end of the swing rod 600 is provided with a first abutting arm 610. The first abutting arm 610 passes through the window 110 and abuts against the push-button switch 200. The sliding component is disposed on the side of the bracket 100 away from the window 110. The sliding component is connected to the other end of the swing rod 600. The sliding component abuts against the other end of the solder layer 500 and the electrode spring 400 respectively. The sliding component is used to drive the swing rod 600 to swing when the solder layer 500 melts, so that the first abutting arm 610 disengages from the button switch 200.

[0049] The principle of the remote signaling switch structure in this embodiment is as follows: A surge protection element 300 is mounted on a bracket 100. The first pin 310 and the second pin 320 of the surge protection element 300 are arranged diagonally. One end of the electrode spring 400 is located on the same side of the bracket 100 as the second pin 320 of the surge protection element. The other end of the electrode spring 400 is welded to the first pin 310 of the surge protection element 300, so that the first pin 310 of the surge protection element is led out to the side where the second pin 320 is located. A sliding assembly is mounted on the bracket 100, and a solder layer 500 is provided in the sliding direction. A first abutting arm 610 is provided at the end of the swing rod 600 to abut against the push-button switch 200 outside the bracket 100. The other end of the swing rod 600 is provided on the sliding assembly, and swings around the pivot 120 as a fulcrum under the drive of the sliding assembly.

[0050] Please refer to Figures 5 to 8When no power surge occurs, and the other end of the electrode spring 400 remains normally connected to the first pin 310 of the surge protection element 300, the sliding assembly cannot move due to the abutment of the solder layer 500. At this time, the swing rod 600 cannot swing, and the first abutting arm 610 presses against the push-button switch 200, causing the button of the push-button switch 200 to be pressed. Please refer to... Figures 9 to 12 When a power surge occurs, the solder layer 500 between the electrode spring 400 and the pin of the surge protection element 300 melts, and the sliding component slides without being restricted by the solder layer 500. At the same time, it drives one end of the swing rod 600 to move. At this time, the swing rod 600 rotates with the pivot 120 on the bracket 100 as the fulcrum. The first abutting arm 610 gradually disengages from the button switch 200. The button of the button switch 200 is no longer pressed and then pops up, thereby sending a remote signal.

[0051] Understandably, compared to the remote signaling triggering structure in the prior art, the remote signaling switch structure in this embodiment has high reliability, requires fewer parts, has lower cost, and is compact in structure and size.

[0052] Please refer to Figure 9 , Figure 10 , Figure 13 as well as Figure 14 Specifically, the other end of the swing rod 600 is provided with a protrusion 620, and the sliding assembly includes a slider 710 and a spring 720. The slider 710 is provided with a second abutting arm 711 and a receiving cavity 712 located on the back of the second abutting arm 711. The second abutting arm 711 abuts against the other end of the solder layer 500 and the electrode spring 400, respectively. The outer end face of the receiving cavity 712 abuts against the side wall of the bracket 100. A column 713 parallel to the second abutting arm 711 is provided inside the receiving cavity 712. The spring 720 is sleeved on the column 713. One end of the spring 720 abuts against the inner end face of the receiving cavity 712, and the other end of the spring 720 abuts against the side wall of the bracket 100. A groove 714 is provided on the side of the slider 710, and the protrusion 620 is received in the groove 714.

[0053] Please refer to Figure 6 and Figure 10 Understandably, in the sliding assembly, the slider 710 can move along the sliding direction under the elastic force of the spring 720. The second abutting arm 711 of the slider 710 abuts against the other end of the solder layer 500 and the electrode spring 400, so as to slide when the solder layer 500 is melted due to power surge, and separate the electrode spring 400 from the first pin 310 of the power surge protection element 300, thereby ensuring electrical safety.

[0054] For example, in this embodiment, the sliding direction of the slider 710 is set to the width direction of the bracket 100, and the slider 710 is disposed close to the surge protection element 300, so that the structure of the bracket 100 is compact.

[0055] Please refer to Figure 3 , Figure 4 , Figure 7 as well as Figure 11 In this embodiment, the bracket 100, surge protection element 300, electrode spring 400, and swing rod 600 are all disposed on the surge protection module of the surge protector, while the push-button switch 200 is disposed on the base of the surge protector. Specifically, the remote signaling switch structure of this embodiment also includes a detachably connected first housing 800 and a second housing 900, wherein the first housing 800 is the outer housing of the surge protection module, and the second housing 900 is the outer housing of the base. The bracket 100 is housed within the first housing 800, and the push-button switch 200 is installed within the second housing 900. The second housing 900 is provided with a clearance hole 930 facing the window 110 to avoid the first abutment arm 610.

[0056] Understandably, when the surge protection module is connected to the base, the first abutting arm 610 on the swing rod 600 passes through the clearance hole 930 and enters the interior of the second housing 900, abutting the push button switch 200. The pins of the surge protection element 300 on the surge protection module are electrically connected to the electrodes of the base. For example, the first pin 310 is led out sequentially through the electrode spring 400 and a pin spring and electrically connected to one of the electrodes of the base; the second pin 320 is led out through another pin spring and electrically connected to the other electrode of the base. When the solder layer 500 melts due to a surge, the slider 710 slides and drives the swing rod 600 to swing. The first abutting arm 610 deflects within the second housing 900, disengaging from the button of the push button switch 200, causing the push button switch 200 to pop up and send a remote signal. The first housing 800 is a rectangular housing with one open side. During actual installation, the surge protection element 300, electrode spring 400, swing rod 600, and slider assembly are first installed on the bracket 100, and then the bracket 100 is installed inside the first housing 800. The second housing 900 is a hollow structure with a side cover. During actual installation, the side cover is opened, the push-button switch 200 and other necessary parts are first installed inside the hollow structure, and then the side cover is installed.

[0057] Please refer to Figure 4 , Figure 5 , Figure 6 as well as Figure 14Optionally, the first housing 800 is provided with a warning window 810, and the slider 710 includes a main body 715, a panel 716 and a support column 717. The panel 716 is positioned opposite the warning window 810, and the support column 717 is connected to the main body 715 and the panel 716 respectively. The second abutment arm 711, the receiving cavity 712 and the groove 714 are all provided on the main body 715.

[0058] Understandably, the above configuration allows staff to observe the status of the surge protector through the warning window 810. For example, in normal operation, the solder layer 500 between the electrode spring 400 and the pin of the surge protection element 300 prevents the slider 710 from moving. Therefore, the panel 716 on the slider 710 can be observed through the warning window 810. When a surge occurs, the solder layer 500 melts, and the slider 710 moves. At this time, the panel 716 on the slider 710 moves away from the position directly opposite the warning window 810. That is, when the panel 716 can be observed through the warning window 810, the surge protector is in normal operation; otherwise, the surge protector is in abnormal operation.

[0059] Please refer to Figure 6 and Figure 10 In some embodiments, the bracket 100 is provided with a first guide wall 130 and a second guide wall 140 that are parallel to each other in its width direction. The first guide wall 130 is disposed between the body 715 of the slider 710 and the surge protection element 300, and the second guide wall 140 is disposed between the panel 716 on the slider 710 and the body 715.

[0060] Understandably, in this embodiment, a first guide wall 130 is provided to separate the slider 710 and the surge protection element 300. At the same time, a second guide wall 140 is provided to separate the body 715 of the slider 710 from the panel 716, so that the slider 710 is disposed between the first guide wall 130 and the second guide wall 140. When the slider 710 slides, the first guide wall 130 and the second guide wall 140 can guide and limit the slider 710.

[0061] Please refer to Figure 6 , Figure 10 , Figure 13 , Figure 14 as well as Figure 15 In some embodiments, the protrusion 620 is U-shaped, and the bottom surface of the groove 714 is also U-shaped. The projected area of ​​the protrusion 620 on the plane containing the bottom surface of the groove 714 is smaller than the bottom surface area of ​​the groove 714.

[0062] Understandably, this embodiment uses a U-shaped groove 714 and a U-shaped protrusion 620, which allows the protrusion 620 and the U-shaped groove 714 to slide better at the contact point during the sliding of the slider 710. In addition, the groove 714 provides enough space for the protrusion 620 to move, avoiding the protrusion 620 from getting stuck or jammed, thereby improving the reliability of the entire structure.

[0063] Please refer to Figure 4 , Figure 5 as well as Figure 15 In some embodiments, the swing arm 600 is flat and positioned above the surge protection element 300. It is understood that positioning the swing arm 600 above the surge protection element 300 makes the internal structure more compact, which is beneficial for miniaturizing the surge protection module design.

[0064] Please refer to Figure 11 Specifically, the remote signaling switch structure also includes a mounting plate 210, on which the push-button switch 200 is mounted. The second housing 900 is further provided with an upper fixing groove 910 and a lower fixing groove 920 for fixing the mounting plate 210. One edge of the mounting plate 210 is engaged in the upper fixing groove 910, and the other opposite edge of the mounting plate 210 is engaged in the lower fixing groove 920. The side of the second housing 900 is provided with mounting holes for placing and removing the push-button switch 200 and the mounting plate 210.

[0065] Understandably, during the actual installation process, the push-button switch 200 is first fixed to the mounting plate 210, and then the mounting plate 210 with the push-button switch 200 is installed onto the second housing 900. For example, one edge of the mounting plate 210 is engaged in the upper fixing groove 910, and the other opposite edge of the mounting plate 210 is engaged in the lower fixing groove 920. The mounting holes facilitate the replacement of the push-button switch 200.

[0066] Please refer to Figure 8 and Figure 12 Preferably, the electrode spring 400 has an outwardly flanged end at the contact point with the second abutment arm 711. The outwardly flanged end of the electrode spring 400 that contacts the second abutment arm 711 facilitates better contact between the second abutment arm 711 and the solder layer 500 during installation, and also helps to better separate the electrode spring 400 from the first pin 310 of the surge protection element 300 when the solder layer 500 melts.

[0067] Please refer to Figure 3 This embodiment also provides a 1U surge protector, including the remote signaling switch structure as described in any of the above claims, wherein the 1U surge protector can be installed in a 1U cabinet.

[0068] In summary, the remote signaling switch structure and 1U surge protector provided by this invention utilize a sliding assembly that abuts the solder layer at the weld between the electrode spring and the surge protection device. A swing rod connects the sliding assembly and a push-button switch. The push-button switch is triggered by the first abutting arm of the swing rod. When the solder layer between the electrode spring and the surge protection device melts due to a surge, the sliding assembly, no longer obstructed by the solder layer, begins to slide, causing the swing rod to swing. This disengages the first abutting arm from the push-button switch, changing the state of the push-button switch and sending a remote signal. The remote signaling switch structure of this application uses a push-button switch, offering high reliability, a small product size, a compact structure, fewer required parts, and lower cost.

[0069] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
