Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] Please refer to Figure 1 - Figure 6 As shown in the figure, the embodiment provides a relay with auxiliary contact monitoring function, which comprises a base 1 and further comprises:

[0028] Two main load static terminals 4 are arranged in the interior of the base 1, and the interior of the base 1 is provided with clamping grooves for clamping the main load static terminals 4;

[0029] A wire package assembly is installed in the interior of the base 1;

[0030] An armature spring contact die seat assembly is arranged outside the wire package assembly;

[0031] An auxiliary contact assembly is arranged outside the wire package assembly;

[0032] A shell 2 is sleeved outside the base 1.

[0033] The working principle is as follows: when the device as a whole needs to be assembled and used, the main load static terminal 4 and the coil assembly are first fixed in the interior of the base 1, and then the auxiliary contact assembly is fixed and installed outside the coil assembly. At this time, the assembly of the magnetic system can be completed. Then the armature spring contact mold base assembly is fixed and installed between the coil assembly, at which time the assembly of the load system and the transmission system can be completed. Finally, the shell 2 is assembled with the base 1 and fixed by glue sealing, so that the assembly of the protection system can be completed. When the normally open main contact in the main load circuit is moved by the armature spring contact mold base assembly to switch from the normally open state to the normally closed state, the auxiliary contact assembly will switch from the normally closed state to the normally open state, so that the main load circuit is monitored according to the closed or open state of the auxiliary contact assembly loop, and whether it is completely disconnected or closed in place is judged, so that the circuit plays a short circuit protection role. The device uses the monitoring ability of the auxiliary contact assembly, so that the relay has the function of short circuit protection of the main load circuit when working, greatly improving the safety and reliability of the relay in use, better meeting the needs of customers and the market, and enhancing the core competitiveness of the product.

[0034] In order to effectively assemble the magnetic system, the coil assembly includes a skeleton 10 fixedly installed in the interior of the base 1. The outer part of the skeleton 10 is fixedly connected with an enameled wire 14. The upper surface of the skeleton 10 is fixedly connected with an iron core 12. One side of the skeleton 10 is fixedly connected with a yoke 13. The outer part of the skeleton 10 is symmetrically provided with a coil leg 11. The interior of the base 1 is provided with a guide groove for the movement of the coil leg 11. When the magnetic system needs to be assembled, the skeleton 10 is first fixedly installed in the interior of the base 1. At this time, the enameled wire 14, the iron core 12, the yoke 13 and the coil leg 11 can be fixedly installed. Then the auxiliary contact assembly is installed on the upper surface of the skeleton 10, at which time the assembly of the magnetic system can be completed, so that the device as a whole can be normally used.

[0035] Considering that the assembly of the load system and the transmission system also needs to be completed when the whole device is used, the armature spring contact die assembly includes the armature 5 above the framework 10, the outer part of the armature 5 is provided with a guide groove for the movement of the yoke 13, the outer part of the yoke 13 is fixedly connected with the hook 17, the armature 5 and the yoke 13 are fixedly installed through the hook 17, the outer part of the armature 5 is provided with the insulating block 15, the bottom of the armature 5 is fixedly connected with the plastic die 16, and the bottom of the plastic die 16 is fixedly connected with the main load moving terminal 8. When the armature spring contact die assembly needs to be fixedly installed, the armature 5 is first inserted into the upper surface of the yoke 13, and then the armature 5 and the yoke 13 are fixedly installed through the hook 17. At this time, the armature spring contact die assembly and the coil assembly can be fixedly installed, so that the assembly of the load system and the transmission system can be completed, and the whole relay can be normally used.

[0036] In order to effectively monitor the main load circuit, the auxiliary contact assembly includes the auxiliary moving terminal 6 and the auxiliary static terminal 7 arranged on the upper surface of the framework 10, and the inner part of the base 1 is provided with guide grooves for the movement of the auxiliary moving terminal 6 and the auxiliary static terminal 7. When the main load circuit needs to be monitored, the auxiliary moving terminal 6 and the auxiliary static terminal 7 are sequentially installed on the upper surface of the framework 10. At this time, the main load circuit can be monitored through the cooperation between the auxiliary moving terminal 6 and the auxiliary static terminal 7. When the normally open main contact in the main load circuit is switched from the normally open state to the normally closed state by the movement of the main load moving terminal 8 driven by the armature spring contact die assembly, the auxiliary moving terminal 6 and the auxiliary static terminal 7 will be switched from the normally closed state to the normally open state, so that the main load circuit can be monitored according to the closed or open state of the auxiliary moving terminal 6 and the auxiliary static terminal 7 loop, and it can be judged whether it is completely disconnected or closed in place, so as to play a short-circuit protection role for the circuit.

[0037] In order to facilitate the positioning and assembly of the base 1 and the shell 2 by the staff, the outer wall of the base 1 is symmetrically provided with the clamping block 3 on both sides, and the outer wall of the shell 2 is provided with the clamping groove for clamping the clamping block 3 on both sides. When the shell 2 needs to be installed outside the base 1, the shell 2 is first sleeved outside the base 1. When the clamping block 3 is clamped into the clamping groove on both sides of the outer wall of the shell 2, the positioning and assembly of the shell 2 and the base 1 can be facilitated, so that the staff can carry out the gluing process.

[0038] In addition, in order to effectively prolong the service life of the relay, a plurality of clamping grooves for clamping the arc extinguishing grid 9 are formed in the inner part of the base 1. The arc extinguishing grid 9 can effectively help to eliminate the generated arc and protect other equipment from the damage of the arc, so as to effectively protect the whole relay and prolong the service life of the whole relay.
