Description

Technical Field

[0001] This invention relates to the field of relay technology, specifically to an auxiliary switch and a nanocrystal relay. Background Technology

[0002] A relay is an electrical control device that causes a predetermined step change in the controlled quantity in the electrical output circuit when the input quantity changes to a specified degree. It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). It is usually used in automated control circuits. In fact, it is an "automatic switch" that uses a small current to control a large current. Therefore, it plays a role in automatic adjustment, safety protection, and circuit switching in the circuit. Existing relays also use auxiliary switches to control the opening and closing of the internal circuit of the relay.

[0003] In practice, auxiliary switches are usually installed on the relay panel, which is then mounted on the relay using bolts or rigid clamps. When a conductor on the auxiliary switch needs to be replaced, additional tools are required, making replacement and maintenance quite troublesome.

[0004] Therefore, this invention proposes an auxiliary switch and a nanocrystal relay to improve this problem. Summary of the Invention

[0005] The purpose of this invention is to provide an auxiliary switch and a nanocrystal relay in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0007] An auxiliary switch, comprising:

[0008] A pre-installed plate with a receiving cavity is provided. A connecting rod is inserted into the pre-installed plate, and an expansion plate is installed on the connecting rod. The diameter of the expansion plate is larger than the diameter of the connecting rod so that a height difference is formed between the connecting rod and the expansion plate.

[0009] A switch box is inserted into a receiving cavity. The switch box is hinged with a plate for insertion into a drop. A connecting spring is installed on the switch box. An insertion rod is installed on the free end of the connecting spring. The plate has a hole for receiving the insertion rod. A limiting plate for resisting the insertion rod is slidably installed on the switch box.

[0010] Furthermore, the switch box has a cavity, and a rotating rod is rotatably installed in the cavity. Two symmetrical clamping plates are slidably installed on the switch box. One end of each clamping plate passes through the switch box and is located inside the cavity. A return spring is installed between the clamping plates. A hinge rod is hinged to the free end of each clamping plate. One end of the rotating rod passes through the inner wall of the switch box and is located on the outside. A drive rod is installed on the other end. Both ends of the drive rod are hinged to the two hinge rods respectively. A protrusion is installed on the outer end of the rotating rod. A fixing plate is installed on the switch box. A pull spring is installed on the fixing plate. A limiting rotating plate is slidably installed on the free end of the pull spring. The limiting rotating plate has a groove for accommodating the protrusion.

[0011] Furthermore, a connecting plate is installed in the cavity, and the clamp is connected to the connecting plate by a wire. A reset spring is installed in the cavity, and a conductor plate is installed on the free end of the reset spring. A switch button is rotatably installed on the switch box, and a contact plate for abutting the conductor plate is installed on the switch button. When the contact plate abuts the conductor plate, a passage is formed between the conductor plate and the connecting plate.

[0012] Furthermore, a water droplet plate is installed on the switch knob shaft, a push spring is installed on the switch box, and a separation plate is installed on the free end of the push spring. The separation plate is used to abut against the rotation limiting plate. When the separation plate abuts against the rotation limiting plate, the protrusion separates from the groove.

[0013] Furthermore, the connecting spring is installed in the cavity, the switch box has a through slot, the insertion rod slides in the through slot, the insertion rod is equipped with a shielding plate for blocking the through slot, and the through slot has a shielding groove for accommodating the shielding plate.

[0014] Furthermore, an inclined surface is provided on the side of the limiting plate that abuts against the separating plate.

[0015] Furthermore, a knob is installed on the outer end of the rotating rod.

[0016] Furthermore, a guide rod is installed on the fixed plate, and a guide hole for accommodating the guide rod is provided on the rotation limiting plate.

[0017] The present invention also provides a nanocrystalline relay, comprising the auxiliary switch described in any of the above claims, and further comprising:

[0018] The relay housing has a receiving groove for accommodating the switch box. The relay housing has a threaded hole, and the connecting rod has an external thread so that the connecting rod is threadedly connected to the threaded hole.

[0019] Furthermore, a conductor rod is installed in the receiving groove, and the clamp is used to clamp the conductor rod.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. In use, the pre-installed plate is pre-connected to the relay. During use, the switch box is inserted into the receiving cavity, and the insert plate is located in the height difference between the connecting rod and the expansion plate. The expansion plate blocks the insert plate, thus limiting the tendency of the switch box to separate from the pre-installed plate. The insertion rod is inserted into the socket, which restricts the rotation of the insert plate. The limiting plate abuts against the insertion rod, thus restricting the sliding of the insertion rod. When disassembly is required, the limiting plate is slid to release the sliding restriction on the insertion rod, and then the insert plate is rotated to separate from the height difference, so that the switch box can be taken out. This increases the convenience of disassembly of the device. Attached Figure Description

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] like Figures 1-10 As shown, an auxiliary switch according to one embodiment of the present invention includes:

[0037] A pre-installed plate 1 has a receiving cavity 101. A connecting rod 102 is inserted into the pre-installed plate 1, and an expansion plate 103 is installed on the connecting rod 102. The diameter of the expansion plate 103 is larger than the diameter of the connecting rod 102 so that a height difference is formed between the connecting rod 102 and the expansion plate 103. In use, the pre-installed plate 1 is connected to the relay in advance. The height difference between the expansion plate 103 and the connecting rod 102 and the outer surface of the pre-installed plate 1 form a cavity.

[0038] The switch box 2 is inserted into the receiving cavity 101. The switch box 2 is hinged with a plug plate 201 for insertion into the drop. During installation, the switch box 2 is inserted into the receiving cavity 101. The inner wall of the receiving cavity 101 blocks and restricts the side wall of the switch box 2. At this time, the plug plate 201 is rotated to insert it into the drop. The expansion plate 103 blocks and restricts the plug plate 201, thereby restricting the tendency of the switch box 2 to separate from the pre-installed plate 1.

[0039] A connecting spring 202 is installed on the switch box 2. An insertion rod 203 is installed on the free end of the connecting spring 202. An insertion hole 204 for accommodating the insertion rod 203 is provided on the insertion plate 201. A limiting plate 205 for resisting the insertion rod 203 is slidably installed on the switch box 2. There are multiple insertion rods 203; in this embodiment, there are four, arranged in pairs and symmetrically distributed on both sides of the switch box 2. Insertion rods 203 on the same side of the connecting spring 202 are close to each other, so that when the insertion plate 201 is rotated and inserted into the drop, the insertion rod 203 will not obstruct the insertion plate 201. After the insertion plate 201 is inserted into the drop, the insertion hole 204 is aligned with the insertion rod 203, allowing passage. The sliding limiting plate 205 moves the insertion rod 203 between the insertion rods 203, causing them to move away from each other and be inserted into the socket 204. At this time, the connecting spring 202 is stretched, applying a force in the opposite direction to the insertion rod 203, causing the insertion rod 203 to contact the limiting plate 205, thereby limiting the sliding of the limiting plate 205 and increasing the stability of the device during use. In addition, the relay and the auxiliary switch are both located in the protective shell during use and are less affected by external forces. Therefore, by forcing the insertion rod 203 to contact and limit the limiting plate 205 through the connecting spring 202, the limiting plate 205 can also be made more stable during use.

[0040] When disassembly is required, the sliding limiting plate 205 releases its resistance to the insertion rod 203. At this time, the connecting spring 202 pulls the insertion rod 203 to separate from the insertion hole 204. Then, the insertion plate 201 is rotated to separate it from the drop, so that the switch box 2 can be separated from the pre-installed plate 1, which increases the convenience of disassembly of the device.

[0041] Compared with the prior art, in use, the pre-installed plate 1 is connected to the relay in advance. In use, the switch box 2 is inserted into the receiving cavity 101. The insertion plate 201 is located in the height difference between the connecting rod 102 and the expansion plate 103. The expansion plate 103 blocks the insertion plate 201, thereby limiting the tendency of the switch box 2 to separate from the pre-installed plate 1. The insertion rod 203 is inserted into the socket 204, which restricts the rotation of the insertion plate 201. The limiting plate 205 abuts against the insertion rod 203, which restricts the sliding of the insertion rod 203. When disassembly is required, the limiting plate 205 is slid to release the sliding restriction on the insertion rod 203. After the insertion plate 201 is rotated to separate from the height difference, the switch box 2 can be taken out, which increases the convenience of disassembly of the device.

[0042] like Figure 4 , Figure 8 and Figure 10As shown, a portion of the structure of the switch box 2 is disclosed. A cavity 3 is provided inside the switch box 2, and a rotating rod 301 is rotatably installed inside the cavity 3. The rotating rod 301 is rotatably installed on the switch box 2 via an axis. Two symmetrical clamping plates 302 are slidably installed on the switch box 2. One end of the clamping plate 302 passes through the switch box 2 and is located inside the cavity 3. A return spring 303 is installed between the clamping plates 302. The return spring 303 forces the clamping plates 302 to move away from each other. When the auxiliary switch and the relay are installed, the conductor on the relay is clamped and connected by sliding the clamping plates 302. The clamping plates 302 are made of copper or other conductive materials. The clamping by the clamping plates 302 increases the connection strength between the device and the relay.

[0043] A hinge rod 304 is hinged to the free end of the clamping plate 302. One end of the rotating rod 301 passes through the inner wall of the switch box 2 and is located on the outside. A drive rod 305 is installed on the other end. The two ends of the drive rod 305 are respectively hinged to the two hinge rods 304. Since there are two clamping plates 302, there are two hinge rods 304, which are designated as rod one and rod two. Rod one and rod two are not on the same plane, so that when rod one and rod two rotate towards each other, their free ends can overlap, which improves the feasibility of the device.

[0044] When the rotating rod 301 rotates, it causes the positions of both ends of the drive rod 305 to change, which in turn causes the position of the hinge rod 304, which is hinged to the drive rod 305, to change, which in turn causes the two clamping plates 302 to move closer to each other.

[0045] A protrusion 306 is installed on the outer end of the rotating rod 301. A fixing plate 307 is installed on the switch box 2. A pull spring 308 is installed on the fixing plate 307. A limiting plate 309 is slidably installed on the free end of the pull spring 308. A groove 3010 for accommodating the protrusion 306 is opened on the limiting plate 309. The pull spring 308 forces the limiting plate 309 to approach the fixing plate 307. When the rotating rod 301 is rotated so that the clamping plates 302 approach each other, the protrusion 306 is aligned with the groove 3010. When the protrusion 306 is inserted into the groove 3010, the inner wall of the groove 3010 blocks and restricts the side wall of the protrusion 306, thereby restricting the rotation of the rotating rod 301.

[0046] When the device is in use, first pull the limiting plate 309 away from the fixed plate 307, then rotate the rotating rod 301. The pulling of the drive rod 305 and the hinge rod 304 forces the two clamping plates 302 to move closer to each other. Then release the limiting plate 309, so that the groove 3010 accommodates the protrusion 306, limiting the rotation of the rotating rod 301. The clamping plates 302 clamp the conductors on the relay, increasing the connection strength of the device. When disassembly is required, pull the limiting plate 309, so that the groove 3010 releases the restriction on the protrusion 306. At this time, the rotation of the rotating rod 301 is restored. When the clamping plates 302 are clamping, the return spring 303 is in a compressed state. When the restriction on the rotating rod 301 is released, the force of the return spring 303 pushes the clamping plates 302 away from each other. Therefore, when disassembling, only the limiting plate 309 needs to be slid, which increases the convenience of the device.

[0047] like Figure 5 and Figure 7 As shown, a portion of the structure within cavity 3 is disclosed. A connecting plate 4 is installed within cavity 3. A clamping plate 302 is connected to the connecting plate 4 via wires. Multiple contacts are installed on the connecting plate 4. Multiple conductors are also installed within the switch box 2. A return spring 5 is installed within cavity 3, and a conductor plate 6 is installed on the free end of the return spring 5. A switch button 7 is rotatably mounted on the switch box 2, and an abutment plate 8 is installed on the switch button 7 for abutting the conductor plate 6. When the abutment plate 8 abuts the conductor plate 6, a passage is formed between the conductor plate 6 and the connecting plate 4. In use, the connecting plate 4, clamping plate 302, and conductor plate... The conductors 6 and 2 in the switch box form a complete circuit, while the return spring 5 forces the conductor plate 6 away from the connecting plate 4, thereby breaking the circuit. The switch button 7 has multiple protrusions on its rotating shaft. The protrusions are made of rubber and can deform. The switch box 2 has a plate with a channel that rotates with the switch button 7. The channel has a groove for accommodating the protrusions. The stability between the switch button 7 and the plate is increased by the switch button 7 being locked in the groove through the protrusions. The switch box 2 has a channel that penetrates its side wall. The free end of the contact plate 8 is located in the cavity 3 through this channel.

[0048] When the device is in use, rotating the switch button 7 causes the contact plate 8 to rotate as well. The contact plate 8 then contacts the conductor plate 6, forcing the conductor plate 6 to approach and contact the connecting plate 4, thus forming a circuit. At this time, the switch button 7 is in the activated state. When the switch button 7 is rotated in the opposite direction, the contact plate 8 is released from contact with the conductor plate 6. The return spring 5 pushes the conductor plate 6 to separate it from the connecting plate 4, thereby breaking the circuit and enabling the switch to function as a switch. At this time, the switch button 7 is in the open circuit state.

[0049] The cavity 3 can also be equipped with structures such as an electromagnetic coil, an iron core, an armature, and a reaction spring, which is consistent with the tripping structure in existing relays. This allows the switch button 7 to be forced to rotate and complete the tripping when the device is short-circuited, thus increasing the safety of the device.

[0050] like Figure 4 and Figure 7 As shown, a portion of the structure of the switch button 7 is disclosed. A water droplet plate 9 is mounted on the rotating shaft of the switch button 7. When the switch button 7 rotates, the free end of the water droplet plate 9 moves in a circular motion around the axis of the rotating shaft of the switch button 7. A push spring 10 is mounted on the switch box 2. A separation plate 11 is mounted on the free end of the push spring 10. The separation plate 11 is used to abut against the rotation limiting plate 309. When the separation plate 11 abuts against the rotation limiting plate 309, the protrusion 306 separates from the groove 3010. When the switch button 7 is in the open circuit state, the free end of the water droplet plate 9 abuts against the separation plate 11, causing the separation plate 11 to abut against the rotation limiting plate 309, forcing the rotation limiting plate 309 away from the fixed plate 307, so that the rotation of the rotating rod 301 is restored. When the switch button 7 is in the start state, the free end of the water droplet plate 9 moves away from the separation plate 11, and the push spring 10 forces the separation plate 11 away from the rotation limiting plate 309, which will not affect the restriction of the rotation of the rotating rod 301, thus increasing the practicality of the device.

[0051] like Figure 6 As shown, a portion of the structure within the cavity 3 is disclosed. A connecting spring 202 is installed within the cavity 3. A through slot 12 is provided on the switch box 2. The insertion rod 203 slides within the through slot 12. A baffle plate 13 is installed on the insertion rod 203 to block the through slot 12. A baffle groove 14 is provided within the through slot 12 to accommodate the baffle plate 13. The connecting spring 202 is located within the cavity 3 and is protected. A plate is installed at the end of the insertion rod 203, and the plate slides within the through slot 12. The baffle plate 13 is connected to the plate body and restricts the side wall of the plate body on the insertion rod 203 through the inner wall of the through groove 12, so that it can only slide in a straight line, which increases the stability of the insertion rod 203 when sliding. When the plate body slides in the through groove 12, the baffle plate 13 also slides in the baffle groove 14, so that the baffle plate 13 will continuously block the through groove 12, reducing the possibility of the cavity 3 communicating with the outside world, reducing the possibility of dust entering the cavity 3 and damaging the electrical components, and increasing the practicality of the device.

[0052] like Figure 4 As shown, the specific structure of the limiting plate 309 is disclosed. The side of the limiting plate 309 that abuts against the separating plate 11 is provided with an inclined surface. When the separating plate 11 abuts against the limiting plate 309, the inclined surface guides the separating plate 11, so that the separating plate 11 can better abut against the limiting plate 309, thereby increasing the feasibility of the device.

[0053] like Figure 4 As shown, the specific structure of the rotating rod 301 is disclosed. A knob 15 is installed on the outer end of the rotating rod 301. The knob 15 is hexagonal prism-shaped, providing a gripping point for the operator, reducing the possibility of slippage when rotating the rotating rod 301, and thus making it easier for the operator to rotate the rotating rod 301.

[0054] like Figure 4 As shown, the specific structure of the fixed plate 307 is disclosed. A guide rod 16 is installed on the fixed plate 307. A guide hole 17 for accommodating the guide rod 16 is provided on the rotation limiting plate 309. The inner wall of the guide hole 17 restricts the side wall of the guide rod 16, forcing the rotation limiting plate 309 and the guide rod 16 to only approach or move away from the fixed plate 307 in a straight line, thereby increasing the stability of the rotation limiting plate 309 when sliding.

[0055] like Figure 11 and Figure 12 As shown, the present invention also provides a nanocrystalline relay, including any of the auxiliary switches described above, and in some embodiments, further including:

[0056] The relay housing 18 has a receiving groove 19 for accommodating the switch box 2. The relay housing 18 also has a threaded hole 20, and the connecting rod 102 has an external thread to connect it to the threaded hole 20. The magnetic material inside the relay is a nanocrystalline material, which improves the contact force between the contacts. Therefore, when a larger instantaneous surge current flows through the contact group, the resulting electrodynamic force cannot cause the closed contact group to open. This improves the relay's ability to withstand overload surge currents. Through project-based testing, the relay can withstand a current of 2700A for 10 seconds at a rated current of 200A, i.e., 13.5Ie / 10s and Ie>200A.

[0057] When the auxiliary switch is installed, the pre-mounted plate 1 is connected to the threaded hole 20 through the connecting rod 102. The receiving cavity 101 is connected to the receiving groove 19 to accommodate the switch box 2. When disassembling, since it is not necessary to disassemble the pre-mounted plate 1, the threaded connection between the pre-mounted plate 1 and the relay housing 18 will not affect the convenience of disassembling the device.

[0058] like Figure 11 As shown, a portion of the structure within the receiving groove 19 is disclosed. A conductor rod 21 is installed within the receiving groove 19, and a clamping plate 302 is used to clamp the conductor rod 21. During use, when the rotating rod 301 rotates, forcing the clamping plates 302 to move closer together, the clamping plates 302 clamp the conductor rod 21, thereby enabling the switch box 2 to complete an electrical connection with the conductor rod 21 through the clamping plates 302. This allows the passage within the switch box 2 to connect with the passage within the relay housing 18, increasing the feasibility of the device.

[0059] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
