Description

Technical Field

[0001] This utility model relates to the field of relay technology, and more specifically, to a high-power relay with auxiliary contact monitoring function. Background Technology

[0002] With the development of new energy technologies such as photovoltaic energy storage, solar energy, and wind energy, the safety conditions for the use of power relays are becoming increasingly stringent, and the service life of the relays themselves is also being required to be higher. At this time, a high-power relay with auxiliary contact monitoring function is needed.

[0003] Existing technologies lack the ability to monitor auxiliary contacts, resulting in low safety and reliability of relay products during use. This fails to better meet the needs of customers and the market, lacks core competitiveness, and cannot satisfy customer requirements.

[0004] Therefore, those skilled in the art have provided a high-power relay with auxiliary contact monitoring function to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a high-power relay with auxiliary contact monitoring function, including a base, and further comprising:

[0006] The outer casing is disposed outside the base;

[0007] A coil assembly is disposed on the upper surface of the base;

[0008] The main load stationary terminals are symmetrically arranged inside the base;

[0009] An armature spring contact mold assembly is disposed outside the coil assembly;

[0010] The auxiliary contact assembly is disposed inside the base;

[0011] The actuating component is located outside the armature spring contact mold assembly.

[0012] As a further improvement to this technical solution, the coil assembly includes a frame fixedly installed on the upper surface of the base, an enameled wire is sleeved on the outside of the frame, an iron core is provided inside the frame, coil legs are symmetrically arranged inside the frame, and a yoke is provided on the outside of the frame.

[0013] As a further improvement to this technical solution, the armature spring contact mold base assembly includes an armature installed outside the yoke, a plastic mold base fixedly connected to the outside of the armature, and a main load moving terminal fixedly connected to the bottom of the plastic mold base.

[0014] As a further improvement to this technical solution, the auxiliary contact assembly includes an auxiliary moving terminal and an auxiliary stationary terminal, which are respectively fixedly installed inside the base.

[0015] As a further improvement to this technical solution, the pushing component includes a plastic insulating pushing block fixedly mounted on the upper surface of the armature.

[0016] As a further improvement to this technical solution, the base is externally fixedly connected with multiple protrusions, and the interior of the outer shell is provided with multiple snap-fit ​​grooves for snapping the protrusions.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In this high-power relay with auxiliary contact monitoring function, the coil assembly, armature spring contact mold base assembly, auxiliary contact assembly, and push assembly are configured. When assembling the relay as a whole, simply install the main load stationary terminal and the coil assembly into the base and fix them. Then, fix the armature spring contact mold base assembly to the outside of the coil assembly. This completes the assembly of the load system and the transmission system. Next, fix the auxiliary contact assembly to the inside of the base, and then install the push assembly to the outside of the armature spring contact mold base assembly. This completes the assembly of the auxiliary structure transmission system. Finally, seal the housing and the base with adhesive to fix them, thus completing the assembly of the relay. When the normally open main contact in the main load circuit drives the contact between the moving terminal and the stationary terminal of the main load to switch from the normally open state to the closed state through the armature spring contact module assembly, the pushing component on the armature spring contact module assembly will move together with the armature spring contact module assembly, thereby driving the auxiliary contact assembly to move. The contacts between the auxiliary contact assemblies will switch from the normally open state to the closed state. Thus, the main load circuit is monitored according to the closed or open state of the contact circuit between the auxiliary contact assemblies to determine whether it is completely open or closed, thereby playing a short-circuit protection role for the circuit, effectively improving the overall safety factor of the relay and extending the overall service life of the relay.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 5 As shown, this embodiment provides a high-power relay with auxiliary contact monitoring function, including a base 1, and further including:

[0028] The outer casing 2 is disposed outside the base 1;

[0029] The coil assembly is disposed on the upper surface of the base 1;

[0030] The main load stationary terminals 11 are symmetrically arranged inside the base 1;

[0031] An armature spring contact mold base assembly is installed outside the in-line package assembly;

[0032] The auxiliary contact assembly is located inside the base 1;

[0033] The push assembly is located outside the armature spring contact mold assembly.

[0034] The working principle described above is as follows: When assembling the relay as a whole, firstly, the main load stationary terminal 11 and the coil assembly are installed and fixed inside the base 1. Then, the armature spring contact mold assembly is fixedly installed outside the coil assembly. At this point, the assembly of the load system and the transmission system is completed. Next, the auxiliary contact assembly is fixedly installed inside the base 1. Then, the push assembly is installed outside the armature spring contact mold assembly. At this point, the assembly of the auxiliary structure transmission system is completed. Finally, the housing 2 and the base 1 are sealed and fixed together, thus completing the assembly of the relay as a whole. When the normally open main contact in the main load circuit passes through the armature... When the reed contact module assembly drives the contact movement between the main load moving terminal 10 and the main load stationary terminal 11 from the normally open state to the closed state, the pushing component on the armature reed contact module assembly will move together with the armature reed contact module assembly, thereby driving the auxiliary contact assembly to move. The contacts between the auxiliary contact assemblies will then switch from the normally open state to the closed state. Thus, the main load circuit is monitored based on the closed or open state of the contact circuit between the auxiliary contact assemblies to determine whether it is completely open or closed, thereby providing short-circuit protection for the circuit, effectively improving the overall safety factor of the relay, and extending the overall service life of the relay.

[0035] To ensure the relay functions properly, the coil assembly includes a frame 4 fixedly mounted on the upper surface of the base 1. Enamelled wire 12 is sleeved on the outside of the frame 4, an iron core 13 is located inside the frame 4, coil feet 7 are symmetrically arranged inside the frame 4, and a yoke 14 is located outside the frame 4. When assembling the load system inside the relay, simply fix the main load stationary terminal 11 and the frame 4 on the base 1. Then, the enamelled wire 12, iron core 13, coil feet 7, and yoke 14 can be fixedly installed, effectively assembling the load system and enabling the relay to function normally.

[0036] Considering that the transmission system needs to be assembled when using the relay, the armature spring contact mold assembly includes an armature 8 installed outside the yoke 14. A plastic mold 15 is fixedly connected to the outside of the armature 8, and the main load moving terminal 10 is fixedly connected to the bottom of the plastic mold 15. When the transmission system needs to be assembled, the armature 8 only needs to be fixedly installed outside the yoke 14. At this time, the armature 8, the plastic mold 15 and the main load moving terminal 10 can all be fixedly installed, thereby effectively assembling the transmission system inside the relay.

[0037] In order to effectively monitor the main load circuit of the relay, the auxiliary contact assembly includes an auxiliary moving terminal 5 and an auxiliary stationary terminal 6, which are respectively fixedly installed inside the base 1. When the normally open main contact in the main load circuit drives the contact between the main load moving terminal 10 and the main load stationary terminal 11 to switch from the normally open state to the closed state through the armature spring contact module assembly, the pushing component on the armature spring contact module assembly will move together with the armature 8, thereby driving the auxiliary moving terminal 5 to move synchronously. At this time, the contact between the auxiliary moving terminal 5 and the auxiliary stationary terminal 6 will switch from the normally open state to the closed state. Thus, the main load circuit is monitored according to the closed or open state of the contact circuit between the auxiliary moving terminal 5 and the auxiliary stationary terminal 6, and it is determined whether it is completely open or closed, thereby providing short-circuit protection for the circuit.

[0038] In order to effectively close the contacts inside the auxiliary moving terminal 5 and the auxiliary stationary terminal 6, the pushing assembly includes a plastic insulating pushing block 9 fixedly mounted on the upper surface of the armature 8. When the normally open main contact in the main load circuit drives the contact between the main load moving terminal 10 and the main load stationary terminal 11 from the normally open state to the closed state through the armature spring contact mold assembly, the plastic insulating pushing block 9 on the armature spring contact mold assembly will move together with the armature 8. Thus, the auxiliary moving terminal 5 can be driven to move synchronously through the plastic insulating pushing block 9. At this time, the contact between the auxiliary moving terminal 5 and the auxiliary stationary terminal 6 will also switch from the normally open state to the closed state. Therefore, the main load circuit is monitored according to the closed or open state of the contact circuit between the auxiliary moving terminal 5 and the auxiliary stationary terminal 6 to determine whether it is completely open or closed, thereby providing short-circuit protection for the circuit and effectively improving the overall practicality of the device.

[0039] In addition, to facilitate the docking and assembly of the base 1 and the housing 2, the base 1 is fixedly connected with multiple protrusions 3 on the outside, and the housing 2 is provided with multiple snap-fit ​​grooves for snapping the protrusions 3 inside. Through the setting of the protrusions 3 and the snap-fit ​​grooves inside the housing 2, it is easy for the workers to dock and assemble the housing 2 and the base 1, thereby facilitating the workers to assemble the relay as a whole and effectively improving the assembly efficiency of the relay.
