[0026] Embodiment
[0027] Such as Figures 1 to 3As shown in the figure, a double-group conversion type U-shaped permanent magnet relay proposed by the present utility model includes: a base 1, and the interior of the base 1 is provided with a hollow structure. A set of sliding mounting seats are arranged on the inner bottom surface of the base 1; a magnetic circuit assembly located inside the base 1, the magnetic circuit assembly includes a bobbin 2, a clamping groove is arranged on the inner wall of one end of the bobbin 2, and the bobbin 2 is horizontally slidably inserted into the interior of the base 1 through the sliding mounting seat. A U-shaped permanent magnet 3 is sleeved inside the bobbin 2, and the U-shaped permanent magnet 3 is located inside the base 1. A coil 4 is wound around the outer wall of the bobbin 2, and an armature 5 is arranged at one end of the bobbin 2; a base 6 fixedly arranged at one end of the base 1, and the base 6 is integrally formed with the base 1. A plurality of clamping grooves are formed on the upper surface of the base 6. Two groups of normally closed static contacts 7 and normally open static contacts 8 are clamped on the base 6 through the clamping grooves, and the normally closed static contacts 7 and the normally open static contacts 8 are arranged at intervals relative to each other. A set of moving contacts 9 are arranged between the normally closed static contacts 7 and the normally open static contacts 8. The moving contact 9 is clamped with the base 6 to realize the control of the circuit; a push piece 10 is arranged above the base 1, and the push piece 10 is movably clamped with the upper surface of the base 1 to make the horizontal movement of the push piece 10 more stable. One end of the push piece 10 is clamped with the armature 5, and the other end of the push piece 10 is inserted into the moving contact 9 to provide a rightward thrust for the moving contact 9 to realize the conversion of the circuit.
[0028] As Figure 2 shown, a leaf spring 11 is clamped at one end of the bobbin 2 through the clamping groove, which can limit the leaf spring 11. The leaf spring 11 is clamped with the lower side of the armature 5 to provide a reset elastic force, which can limit the armature 5 and make the upper end of the armature 5 deflect stably and slightly.
[0029] Furthermore, two coil terminals 12 are penetrated through the base 1, and the coil terminals 12 are bent at 90 degrees, and the bent part is closely attached to the inner bottom surface of the base 1. The upper ends of the coil terminals 12 are respectively connected to both ends of the coil 4, which can connect the coil 4 to the circuit and generate a stable magnetic field.
[0030] Secondly, first contacts 13 are respectively arranged on the opposite surfaces of the normally closed static contacts 7 and the normally open static contacts 8, which can form a better butt joint when contacting, so as to reduce the contact resistance and improve the contact reliability of the circuit.
[0031] Furthermore, a second contact 14 is penetrated through the moving contact 9, and the second contact 14 is located between the first contacts 13, reducing the moving path of the second contact 14, thereby reducing the resistance and inductance and improving the efficiency of the circuit.
[0032] As Figure 1 and Figure 2 shown, first terminals 15 are fixedly connected to the lower ends of the normally closed static contacts 7 and the normally open static contacts 8. The first terminals 15 penetrate through the base 6 and extend to the outside, facilitating the connection of the circuit.
[0033] In addition, a second terminal 16 is fixedly arranged at the lower end of the moving spring 9. The second terminal 16 penetrates through the base 6 and extends to the outside, facilitating the connection of the circuit and realizing the control of the circuit.
[0034] Again, a clamping block 17 is fixedly arranged at the upper end of the armature 5, and the clamping block 17 is integrally formed with the armature 5.
[0035] As Figure 1 and Figure 2 shown, a clamping groove 18 is formed at one end of the push piece 10, and the clamping groove 18 is located above the clamping block 17 and is sleeved with the clamping block 17. Two insertion blocks 19 are fixedly arranged at the other end of the push piece 10 and are opposite to the moving spring 9 respectively.
[0036] Finally, insertion holes 20 are formed in the moving spring 9 respectively, and the insertion holes 20 are inserted into the insertion blocks 19, facilitating the movement of the moving spring 9.
[0037] The working principle of this embodiment is as follows: The coil terminal 12 is energized, and the coil terminal 12 applies a positive voltage to the coil 4. According to Ampere's circuital law, the current passing through the coil 4 generates a magnetic field, causing opposite magnetic poles to the current direction to be formed on both sides of the U-shaped permanent magnet 3, so that the U-shaped permanent magnet 3 attracts the coil 4, and the upper end of the coil 4 deflects through the limit of the elastic piece 11.
[0038] The coil 4 drives the push piece 10 to move rightward on the upper side of the base 1 through the cooperation of the clamping block 17 and the clamping groove 18. The push piece 10 drives the upper ends of a group of moving springs 9 to deflect rightward simultaneously through the cooperation of the insertion blocks 19 and the insertion holes 20. The moving spring 9 drives the second contact 14 to fit with the first contact 13 on the normally open static spring 8, which can meet different circuit requirements. When the circuit requirements change, the user does not need to replace the entire relay or add additional conversion devices. Just through the conversion mechanism inside the relay, different circuit connection methods can be easily realized, which not only improves the application range of the relay, but also greatly reduces the maintenance cost and the complexity of use.
[0039] The above specific embodiments are only several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
