[0044] Embodiment one

[0045] The remote signaling device can increase the downward pressing stroke of the trigger, avoid the state of the remote signaling device from switching and misissuing the alarm signal in the non-alarm situation, and further ensure the working reliability of the remote signaling device.

[0046] Specifically, as shown in the figure, Figures 1 to 3 The remote signaling device is installed into the base 4, and the remote signaling device includes a micro switch 1 and a trigger 2. The micro switch 1 has a switch button 11. The trigger 2 is made of elastic material, that is, the trigger 2 can be elastically deformed. The trigger 2 is located above the switch button 11 and includes a first plate 21 and a second plate 22 connected with each other. The second plate 22 is inclined relative to the first plate 21. The first plate 21 is used to contact and press the switch button 11 downward along the Z-axis. The included angle α between the first plate 21 and the second plate 22 is obtuse. When the second plate 22 is pressed downward along the Z-axis, the included angle α between the second plate 22 and the first plate 21 gradually increases, that is, the bending connection between the first plate 21 and the second plate 22 is elastically deformed, so that the first plate 21 has a first stroke downward along the Z-axis, and the second plate 22 has a second stroke downward along the Z-axis. When the second plate 22 is loose in the non-alarm situation, the second plate 22 moves upward along the Z-axis to release the second stroke, and the first plate 21 can continue to press the switch button 11.

[0047] Compared with the prior art, the remote signaling device in this embodiment changes the structure of the trigger member 2, and bends the first plate 21 and the second plate 22 to form a bent structure that can increase the trigger stroke; by making the material of the trigger member 2 an elastic material, the trigger member 2 is located above the switch button 11 of the micro switch 1, and the trigger member 2 includes a first plate 21 and a second plate 22 connected to each other, and the second plate 22 is tilted relative to the first plate 21, and the angle α between the second plate 22 and the first plate 21 is an obtuse angle; when the second plate 22 is pressed downward along the Z axis, the first plate 21 can contact and press the switch button 11 downward along the Z axis to compress the switch button 11, so that the micro switch 1 does not issue an alarm signal. In this process, the trigger stroke of the first plate 21 pressing the switch button 11 downward along the Z axis is the first stroke; thereafter, in the process of continuing to press the second plate 22 downward along the Z axis, due to the contact between the second plate 22 and the first plate 21, the trigger member 2 is located above the switch button 11. The bent connection between the plates 21 can undergo elastic deformation, so that the angle α between the second plate 22 and the first plate 21 gradually increases until the first plate 21 and the second plate 22 approach the same horizontal plane. Correspondingly, the first plate 21 can continue to press the switch button 11 downward along the Z axis to further compress the switch button 11. In this process, the downward movement stroke of the second plate 22 along the Z axis is the second stroke; the first plate 21 and the second plate 22 connected by a bending connection can increase the trigger stroke for pressing the switch button 11 downward. When the second plate 22 becomes loose under non-alarm conditions, the second plate 22 moves upward along the Z axis to release the second stroke. Since the first stroke still exists at this time, the first plate 21 can continue to press the switch button 11 downward along the Z axis under the action of the first stroke, so that the micro switch 1 will not mistakenly send an alarm signal, thereby better ensuring the working reliability of the remote signaling device.

[0048] Furthermore, if Figure 1 and Figure 2 As shown, the trigger member 2 further includes a positioning plate 24 , which is connected to an end of the second plate 22 that is not connected to the first plate 21 , so as to press the second plate 22 downward along the Z-axis through the positioning plate 24 .

[0049] Specifically, if Figure 1 and Figure 2 As shown, the base 4 includes a limiting plate 44 , a positioning opening 441 is formed on the limiting plate 44 , and the positioning plate 24 is limited to pass through the positioning opening 441 so that the limiting plate 44 can abut against the second plate 22 .

[0050] By setting up the positioning plate 24 and the positioning opening 441 that cooperate with each other, on the one hand, the trigger member 2 can be accurately positioned in the base 4; on the other hand, after the positioning plate 24 is limited to pass through the positioning opening 441, it is beneficial for the limiting plate 44 to directly abut the second plate 22, so that the limiting plate 44 can subsequently press the second plate 22 downward along the Z axis.

[0051] Further, as shown in Figure 2 and Figure 5 , the thickness of the limiting plate 44 gradually decreases along the extension direction of the first plate 21 to the second plate 22, on the one hand, so that the limiting plate 44 can better avoid the bending structure between the first plate 21 and the second plate 22, so as to avoid interference with the elastic deformation of the bending connection between the second plate 22 and the first plate 21; on the other hand, it is beneficial to the direct abutment between the limiting plate 44 and the second plate 22, and beneficial to the direct pressing of the second plate 22 by the limiting plate 44 along the Z-axis to move downward.

[0052] Specifically, the trigger 2 further comprises a rotating shaft connected to one end of the first plate 21 not connected to the second plate 22.

[0053] Further, as shown in Figures 4 to 7 , the inner part of the base 4 is respectively provided with an arc-shaped groove 42, a first plug-in hole 43 and a second plug-in hole 41 in communication, the rotating shaft is rotationally arranged in the arc-shaped groove 42, and the opposite ends of the rotating shaft are respectively rotationally arranged in the first plug-in hole 43 and the second plug-in hole 41.

[0054] By rotationally arranging the rotating shaft in the arc-shaped groove 42, the first plug-in hole 43 and the second plug-in hole 41, on the one hand, the rotating shaft can provide support for the entire trigger 2, and the trigger 2 is supported and arranged in the inner part of the base 4, so that the trigger 2 can work stably; on the other hand, the elastic deformation of the first plate 21 and the second plate 22 can be matched by the rotation of the rotating shaft, so as to avoid interference with the elastic deformation of the first plate 21 and the second plate 22, and further to ensure the smoothness of the elastic deformation of the bending connection between the second plate 22 and the first plate 21.

[0055] Specifically, as shown in Figure 3 and Figure 7 , the rotating shaft comprises a hollow semicircular cylinder 231, one end of the first plate 21 away from the second plate 22 is connected to an outer edge 2311 of the hollow semicircular cylinder 231, and the opening 2312 of the hollow semicircular cylinder 231 faces the first plate 21, so that the hollow semicircular cylinder 231 can be in contact with the arc-shaped groove 42, and the support effect of the rotating shaft is ensured.

[0056] By arranging the hollow semicircular cylinder 231, on the one hand, the processing of the hollow semicircular cylinder 231 is relatively simple, and on the other hand, the processing between the hollow semicircular cylinder 231 and the first plate 21 with relatively thin thickness is relatively easy, so that the processing of the entire trigger 2 is relatively simple and convenient, and the processing cost is relatively low.

[0057] In other embodiments, as shown in Figure 8As shown, the rotating shaft can further include an elongated plate 232 and a bent plate 233; the elongated plate 232 and the bent plate 233 are integrally formed, the elongated plate 232 is connected to one end of the first plate 21 away from the second plate 22, the elongated plate 232 is located in the same plane as the first plate 21, and the elongated plate 232 is rotatably arranged in the arc-shaped groove 42; the bent plate 233 is bently connected to each of the opposite ends of the elongated plate 232, and the two bent plates 233 are rotatably arranged in the first insertion hole 43 and the second insertion hole 41, respectively. Here, the specific structure of the rotating shaft is not limited, as long as it can facilitate processing and at the same time realize the functions of support and rotation.

[0058] By arranging the connected elongated plate 232 and bent plate 233, on the one hand, the processing of the elongated plate 232 and the bent plate 233 is relatively simple, and on the other hand, the processing between the elongated plate 232 and the first plate 21 with relatively thin thickness is relatively easy, so that the processing of the entire trigger 2 is relatively simple and convenient, and the processing cost is relatively low.

[0059] Specifically, as shown in Figure 2 and Figure 3 the first plate 21 and / or the second plate 22 are flat plates, on the one hand, the structure of the flat plate can facilitate the installation of the trigger 2 in a narrow space, making the installation of the trigger 2 relatively simple and smooth; on the other hand, the structure of the flat plate can reduce the occupied space to provide available space for the trigger stroke to ensure the smooth generation of the first stroke and the second stroke. In the embodiment, the first plate 21 and the second plate 22 are both flat plates.

[0060] Further, the thickness of the flat plate is 0.25mm-0.3mm, so that the thickness of the first plate 21 and the second plate 22 is relatively thin, which can be more conducive to the installation of the trigger 2 in a narrow space, and can provide more available space for the formation of the trigger stroke; the hardness of the flat plate is 310HV-370HV, that is, the material of the first plate 21 and the second plate 22 is a material with a certain hardness, so that the structural hardness of the entire trigger 2 is good, so as to ensure the structural hardness between the first plate 21 and the second plate 22, thereby avoiding the risk of breakage of the second plate 22 and the first plate 21 during pressing. The material of the trigger 2 in the embodiment can be stainless steel material, so that the entire trigger 2 can have certain elastic deformation and hardness at the same time, and the entire trigger 2 is an integrally formed structure.

[0061] Specifically, as shown in Figure 3As shown, the included angle a between the second plate 22 and the first plate 21 is 160-170°, so that the included angle a between the first plate 21 and the second plate 22 is more appropriate, thereby facilitating the elastic deformation of the bending connection between the first plate 21 and the second plate 22, and further ensuring the smoothness of the second stroke. In this embodiment, the included angle a between the second plate 22 and the first plate 21 is 165°.

[0062] Further, as shown in the figure, Figure 2 The remote signaling device further includes an electronic circuit board 3, and the micro switch 1 is arranged on the electronic circuit board 3 and electrically connected with the electronic circuit board 3, so as to obtain the signal of the micro switch 1 through the electronic circuit board 3 and transmit the signal of the micro switch 1 out through the electronic circuit board 3. The electronic circuit board 3 can adopt the common electronic circuit board structure in the prior art.

[0063] The remote signaling device in this embodiment, as shown in the figure, Figure 3 The first plate 21 and the second plate 22 are connected in an inclined manner, so that when the second plate 22 is pressed downward along the Z axis, the elastic deformation occurs at the bending connection between the first plate 21 and the second plate 22, thereby enabling the first plate 21 to have a first stroke and the second plate 22 to have a second stroke, and further enabling the second stroke to be released first in the case of non-alarm loosening, so that the micro switch 1 will not mistakenly send an alarm signal under the action of the first stroke.

Specifically, the pluggable module contacts and presses the positioning plate 24 downward along the Z axis, so as to press the second plate 22 downward along the Z axis through the positioning plate 24. The base 4 and the pluggable module are specifically the common structure in the prior art surge protector, and the working principle thereof will not be described in detail here.
