Although such a relay can also generate a certain electromagnetic attraction, the electromagnetic attraction generated by only one coil is small. After the relay is used for a long time, it will cause damage to the relay, which will affect the service life of the relay, and then increase the user's maintenance costs, and its practicality is low.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] See also Figure 1 - Figure 7 As shown, this embodiment provides a double-coil relay, including a base 1, and also including:
[0029] A housing 2 is arranged outside the base 1;
[0030] A mounting seat 4, arranged on the upper surface of the base 1;
[0031] A reinforcing component is symmetrically arranged on the upper surface of the mounting seat 4 and is used to enhance the electromagnetic attraction of the relay, thereby extending the service life of the relay;
[0032] A fixing plate 5 is located above the base 1. The front and rear surfaces of the fixing plate 5 are provided with snap-in grooves for snap-in connection with the mounting seat 4. A connecting plate 6 is provided below the fixing plate 5. A guide groove for movement of the fixing plate 5 is provided on the upper surface of the connecting plate 6. An inner plate 10 is provided inside the connecting plate 6. A mounting plate 11 is fixedly connected to the bottom of the inner plate 10.
[0033] The matching plate 13 is symmetrically arranged inside the base 1 .
[0034] The above working principle: by strengthening the setting of the components, the relay can generate electromagnetic attraction not only through a single coil body 3, but also through two coil bodies 3. The electromagnetic attraction generated by the two coil bodies 3 is greater than the electromagnetic attraction generated by one coil, thereby effectively extending the overall service life of the relay, and then effectively reducing the user's maintenance cost, and at the same time effectively improving the practicality of the relay.
[0035] In order to conveniently fix the mounting base 4 on the base 1, the front and rear inner walls of the base 1 are provided with snap-in grooves for snapping the mounting base 4. When the mounting base 4 needs to be fixedly installed on the base 1, it is only necessary to insert the mounting base 4 into the snap-in grooves provided on the front and rear inner walls of the base 1. At this time, the mounting base 4 can be fixedly installed on the base 1 without using tools such as bolts, thereby effectively improving the installation efficiency of the mounting base 4.
[0036] Taking into account that when the relay is in use, the electromagnetic attraction generated by the two coil bodies 3 is greater than that generated by one coil body 3, thereby effectively extending the service life of the relay, the reinforcing component includes a skeleton 7 symmetrically arranged on the upper surface of the mounting seat 4, the outside of the two skeletons 7 are both sleeved with the coil bodies 3, the upper surfaces of the two skeletons 7 are penetrated by through holes 8 for the movement of the T-shaped plates 9, and the upper surface of the mounting seat 4 is provided with a clamping groove for clamping the T-shaped plates 9. Through the arrangement of the two coil bodies 3, the electromagnetic attraction of the relay as a whole can be effectively improved, thereby effectively extending the service life of the relay as a whole. When the two coil bodies 3 need to be installed, it is only necessary to place the two skeletons 7 on the upper surface of the mounting seat 4, and then pass multiple T-shaped plates 9 through the inside of the through holes 8, and then insert the multiple T-shaped plates 9 into the clamping grooves on the upper surface of the mounting seat 4. At this time, the skeletons 7 and the coil bodies 3 can be fixed and installed, saving time and effort.
[0037] In order to further improve the installation firmness between the mounting seat 4, the fixing plate 5 and the base 1, a fixing plate 15 is provided between the mounting seat 4 and the base 1, and spring plates 16 are symmetrically provided inside the fixing plate 15. The inner wall of the base 1 is provided with a guide groove for the spring plates 16 to move. Through the arrangement of the fixing plate 15 and the spring plates 16, the installation firmness between the mounting seat 4, the fixing plate 5 and the base 1 can be further improved, thereby further improving the overall stability of the relay.
[0038] In order to enable the relay to be used normally, the first contacts 12 are symmetrically arranged inside the mounting plate 11. Through the setting of the first contacts 12, the relay can perform normal circuit opening and closing processing, so that the relay can be used normally. If there is no contact inside the relay, the relay cannot be used normally.
[0039] In addition, the relay cannot be used normally only by setting the first contact 12, so the two matching plates 13 are fixedly connected to the inside with a second contact 14 that matches the first contact 12. Through the setting of the second contact 14, the first contact 12 and the second contact 14 can be in contact or away from each other, so that the relay can achieve the circuit opening and closing effect. When the coil body 3 is energized, the first contact 12 and the second contact 14 will be in contact. At this time, the circuit is connected and the equipment can operate normally. When the coil body 3 is powered off, the first contact 12 and the second contact 14 will be separated. At this time, the circuit is disconnected and the equipment will stop working. At this time, the relay can be used normally.
[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
