Description

Technical Field

[0001] This utility model relates to the field of electronic component technology, specifically to a micro switch that can be quickly installed. Background Technology

[0002] A micro switch is a switch that uses very little force. It is a switch in which external mechanical force acts on an actuating spring through a transmission element, causing the stationary contact at its end to quickly connect or disconnect with the moving contact. A micro switch has a small contact interval and a quick-acting mechanism. The contact mechanism, which performs the switching action with a specified stroke and force, is covered by a housing, has an external actuator, and is relatively small in size.

[0003] Patent CN211654649U discloses a micro switch that is easy to install. This patent uses a quick-installation structure to connect the external metal plate of the micro switch body to the corresponding external connecting wire. The structure mainly includes: a mounting slot, two fixed support plates, a return spring, a clamp, and a clamp shaft. When the operator presses the clamp's push handle, the clamp compresses the return spring around the clamp shaft. Then, the corresponding external connecting wire is placed inside the mounting slot, ensuring it is in close contact with the external contact plate. The operator then releases the clamp's push handle. This simple pressing completes the connection between the external contact plate and the corresponding external wire, eliminating the need for welding and resulting in extremely high installation efficiency. However, this patent still has the following problems in practical use:

[0004] The microswitch body uses a quick-installation structure to connect the external metal plate to the corresponding external wire. The connection between the external contact plate and the corresponding external wire is completed with a simple press. Not only is welding not used, but the installation efficiency is also extremely high. However, in actual use, the connection wire is mainly fixed by the pressure of the clamp. After fixing, the clamp can still move. Once the clamp moves, the connection wire may fall off, making the connection wire not secure and posing a risk of falling off.

[0005] A micro switch that can be quickly installed is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a micro switch that can be quickly installed, in order to solve the problem mentioned in the background art where the current quick-installation structure connects the external metal plate and the corresponding external wire in the micro switch body. The connection between the external contact plate and the corresponding external wire is completed by simple pressing, which not only eliminates the need for welding but also has extremely high installation efficiency. However, in actual use, the connection wire is mainly fixed by the pressure of the clamp, and the clamp can still move after fixing. Once the clamp moves, the connection wire may fall off, making the connection wire not securely fixed and posing a risk of falling off.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a micro switch that can be quickly installed, comprising a micro switch body;

[0008] The micro switch body has a neutral wire contact and a live wire contact symmetrically arranged on one side, and a ground wire contact is arranged on one side of the bottom of the micro switch body.

[0009] Also includes:

[0010] The neutral wire connector, live wire connector, and ground wire connector are each provided with a fixing component on one side, and the micro switch body is provided with a mounting component on the other side of the bottom.

[0011] The fixing assembly includes several fixing brackets that are fixedly connected to the neutral wire connector, the live wire connector and the ground wire connector respectively. A sliding rod is slidably connected to the center of the fixing bracket. A positioning plate is fixedly installed at the bottom of the sliding rod and a pull ring is fixedly installed at the top of the sliding rod.

[0012] A return spring is fitted around the lower outer side of the sliding rod. One end of the return spring is fixedly connected to the fixing frame, and the other end of the return spring is fixedly connected to the positioning plate. Guide rods are symmetrically installed on both sides of the top of the positioning plate on both sides of the sliding rod. A positioning block is fixedly installed on the top of the guide rod, and the guide rod is slidably connected to the fixing frame.

[0013] Preferably, the top of the fixing frame is symmetrically rotatably connected with a rotating rod, and a fixing block is fixedly installed on the top of the rotating rod. A telescopic spring is sleeved on the outside of the rotating rod, and a connecting block is fixedly installed on one end of the telescopic spring, and the connecting block is fixedly connected to the rotating rod.

[0014] Preferably, a sliding sleeve is fitted on the upper outer side of the rotating rod, and the sliding sleeve is slidably connected to the rotating rod. The sliding sleeve is also fixedly connected to the telescopic spring, and handles are symmetrically installed on the top of the sliding sleeve.

[0015] Preferably, a positioning rod is fixedly installed on one side of the sliding sleeve, and a positioning groove is provided on the top of the positioning block, and the positioning rod is engaged with the positioning groove.

[0016] Preferably, the mounting assembly includes a mounting bracket fixedly mounted on the other side of the bottom of the micro switch body, and a threaded sleeve is fixedly connected through one side of the mounting bracket, and a threaded rod is threadedly connected inside the threaded sleeve, with a knob fixedly mounted at one end of the threaded rod and a clamping plate movably connected at the other end of the threaded rod.

[0017] Preferably, a limiting sleeve is fixedly connected through one side of the mounting bracket, and a limiting rod is slidably connected inside the limiting sleeve, and the limiting rod is fixedly connected to the clamping plate.

[0018] Preferably, a number of rubber protrusions are fixedly installed on the side of the clamp plate near the micro switch body.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This micro switch, which can be quickly installed, has a fixing component on one side of the neutral wire contact, live wire contact, and ground wire contact, which facilitates the user in fixing the connecting wires. Furthermore, the fixing of the connecting wires ensures reliable fixation, preventing them from easily coming loose, thus improving convenience and practicality. The specific details are as follows:

[0020] 1. A fixing component is installed on one side of the neutral wire connector, live wire connector, and ground wire connector. When fixing the connecting wire, pulling the pull ring causes the sliding rod to slide on the fixing frame. As the sliding rod moves, it compresses the return spring and lifts the positioning plate. As the positioning plate moves, it causes the guide rod to slide on the fixing frame, thus limiting the movement of the positioning plate. Place the connecting wire at the bottom of the positioning plate, release the pull ring, and the return spring will return to its original deformation, thus fixing the connecting wire on the positioning plate. Then, pull the handle to cause the sliding sleeve to slide on the rotating rod. As the sliding sleeve moves, it can stretch the connecting block. The telescopic spring on the top of the positioning rod positions it above the positioning block. Then, rotating the rotating rod aligns the positioning rod with the positioning groove on the positioning block. Under the action of the telescopic spring, the positioning rod engages with the positioning groove, limiting the guide rod's position. The telescopic spring is in a stretched state, preventing the guide rod from moving easily and thus preventing the positioning plate from moving easily. This makes it easier for the connecting wire to loosen after it is fixed. The fixing component facilitates the user's fixation of the connecting wire, and the reliability of the fixation ensures that the connecting wire will not easily fall off, improving convenience and practicality.

[0021] 2. An installation component is provided on one side of the bottom of the micro switch body. When installing the micro switch body, align one side of the clamping plate with one side of the plane to be installed. Then, rotate the knob to drive the threaded rod to rotate. The threaded rod can move through the threaded connection with the threaded sleeve on the mounting bracket, so that the threaded rod can drive the clamping plate to move. At the same time, the clamping plate can drive the limit rod to slide on the limit sleeve, thereby limiting the movement of the clamping plate. This allows the clamping plate and the micro switch body to fit against the plane to be installed, so that the micro switch body can be installed and fixed. The installation component makes it easy for users to install and fix the micro switch body, improving convenience and practicality. Attached Figure Description

The fixing component 2 facilitates the user to fix the connecting wire, and the fixing of the connecting wire can ensure the reliability of the fixation, so that the connecting wire will not easily fall off, thus improving convenience and practicality.

[0030] A rotating rod 207 is symmetrically rotatably connected to the top of the fixed frame 201, and a fixing block 208 is fixedly installed on the top of the rotating rod 207. A telescopic spring 209 is sleeved on the outside of the rotating rod 207, and a connecting block 210 is fixedly installed on one end of the telescopic spring 209. The connecting block 210 is fixedly connected to the rotating rod 207, allowing the rotating rod 207 to rotate on the top of the fixed frame 201.

A positioning rod 213 is fixedly installed on one side of the sliding sleeve 211, and a positioning groove 214 is formed on the top of the positioning block 2061. The positioning rod 213 engages with the positioning groove 214, allowing the guide rod 206 to be limited. The mounting assembly 3 includes a mounting bracket 301 fixedly mounted on the other side of the bottom of the micro switch body 1. A threaded sleeve 302 is fixedly connected through one side of the mounting bracket 301, and a threaded rod 303 is threadedly connected inside the threaded sleeve 302. A knob 304 is fixedly mounted on one end of the threaded rod 303, and a clamping plate 305 is movably connected to the other end of the threaded rod 303.

[0031] Working principle: Before using this quick-installation micro switch, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 5As shown, a fixing component 2 is provided on one side of the neutral wire connector 101, the live wire connector 102, and the ground wire connector 103. When fixing the connecting wire, pulling the pull ring 205 causes the sliding rod 202 to slide on the fixing frame 201. While the sliding rod 202 moves, it can compress the return spring 204 and lift the positioning plate 203. While the positioning plate 203 moves, it causes the guide rod 206 to slide on the fixing frame 201, thereby limiting the movement of the positioning plate 203. The connecting wire is placed at the bottom of the positioning plate 203. The pull ring 205 is released, and the return spring 204 returns to its deformation, so that the positioning plate 203 fixes the connecting wire. Then, pulling the handle 212 causes the sliding sleeve 211 to slide on the rotating rod 207. The sliding sleeve 211 moves... Simultaneously, the telescopic spring 209 on the connecting block 210 can be stretched, so that the positioning rod 213 is positioned above the positioning block 2061. Then, the rotating rod 207 is rotated so that the positioning rod 213 aligns with the positioning groove 214 on the positioning block 2061. Under the action of the telescopic spring 209, the positioning rod 213 engages with the positioning groove 214, so that the guide rod 206 is limited and the telescopic spring 209 is in a stretched state, so the guide rod 206 will not move easily, so that the positioning plate 203 will not move easily, so that the connecting wire is not easy to loosen after it is fixed. The fixing component 2 makes it easy for users to fix the connecting wire, and the reliability of the fixing can be guaranteed after the connecting wire is fixed, so that the connecting wire will not easily fall off, improving convenience and practicality.

[0032] An installation component 3 is provided on one side of the bottom of the micro switch body 1. When installing the micro switch body 1, one side of the clamping plate 305 is aligned with one side of the plane to be installed. Then, the knob 304 is rotated to drive the threaded rod 303 to rotate. The threaded rod 303 can move through the threaded connection with the threaded sleeve 302 on the mounting bracket 301, so that the threaded rod 303 can drive the clamping plate 305 to move. While the clamping plate 305 is moving, it can drive the limiting rod 306 to slide on the limiting sleeve 307, so as to limit the movement of the clamping plate 305. This allows the clamping plate 305 and the micro switch body 1 to fit against the plane to be installed, so that the micro switch body 1 can be installed and fixed. The installation component 3 makes it easier for users to install and fix the micro switch body 1, improving convenience and practicality.
