[0018] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0019] like Figures 1 to 4As shown, it is a schematic diagram of the structure of a glue-free three-phase relay provided by the utility model. The glue-free three-phase relay includes a housing 10, a coil assembly 20 arranged in the housing 10, a magnetic steel assembly 30 arranged on one side of the coil assembly 20, and three electrical connection assemblies 40 arranged in the housing 10 on both sides of the coil assembly 20. It can be imagined that the glue-free three-phase relay also includes some other functional structures, such as wiring terminals, slots, etc., which are well known to those skilled in the art and will not be repeated here.

[0020] The housing 10 includes a base 11 and a cover 12 buckled on the base 11 .

[0021] The base 11 includes a coil portion 111 for setting the coil assembly 20, a magnetic steel portion 112 arranged on one side of the coil portion 111 for setting the magnetic steel assembly 30, and electrical connection portions 113 arranged on both sides of the coil portion 111 for setting the electrical connection assembly 40.

[0022] The openings of the coil portion 111, the magnetic steel portion 112 and the electrical connection portion 113 are all provided with chamfers to play a guiding role, so as to facilitate the assembly of the coil assembly 20, the magnetic steel assembly 30 and the electrical connection assembly 40. The magnetic steel portion 112 penetrates the coil portion 111 and the electrical connection portion 113, so as to connect the coil assembly 20 and the electrical connection assembly 40 through the magnetic steel assembly 30. Each of the electrical connection portions 113 and the side end surface of the base 11 is provided with an opening 114, and inclined surfaces are provided on both sides of the opening 114 to facilitate the assembly of the electrical connection assembly 40.

[0023] A plurality of blocks 115 are arranged at intervals near the opening of the base 11. The surroundings of the blocks 115 are sunken. The blocks 115 are inclined toward the opening of the base 11 to play a guiding role, so that the base 11 and the cover 12 are buckled together.

[0024] The cover plate 12 includes a cover plate body 121 , a plurality of compatible sockets 122 arranged on the cover plate body 121 at the electrical connection portion 113 , and a plurality of buckles 123 arranged around the cover plate body 121 .

[0025] The position and number of the buckles 123 correspond to the block 115. The cover body 121 is buckled with the block 115 through the buckles 123, thereby completing the assembly of the housing 10. The compatible socket 122 can be connected to the electrical connection portion 113 through a cable.

[0026] A relief groove 124 is disposed at a position of the cover body 121 corresponding to the buckle 114 . Both sides of the opening of the relief groove 124 are provided with inclined surfaces. The relief groove 124 cooperates with the opening 114 to fix the electrical connection component 40 .

[0027] The coil assembly 20 includes a coil frame 21 and an electromagnetic coil 22 disposed on the coil frame 21. When the electromagnetic coil 22 is energized, a magnetic field is generated to drive the magnetic steel assembly 30. The coil assembly 20 is prior art and will not be described in detail herein.

[0028] The magnetic steel assembly 30 includes a permanent magnet 31 rotatably arranged on one side of the coil assembly 20, and a paddle 32 connected to the permanent magnet 31. The paddle 32 is slidably arranged in the magnetic steel portion 112. Both ends of the paddle 32 are connected to the electrical connection assembly 40. Thus, the paddle 32 is driven to slide by the rotation of the permanent magnet 31 to adjust the switch state of the electrical connection assembly 40. The permanent magnet 31 is a prior art and will not be described in detail here.

[0029] Each of the electrical connection components 40 includes two static springs 41, a dynamic spring 42 disposed on one side of the static spring 41, and two contacts 43 disposed on the static spring 41 and the dynamic spring 42. One end of the static spring 41 extends from the opening 114 to the outside. One end of the dynamic spring 42 abuts against the paddle 32.

[0030] When in use, the coil assembly 20 is energized to generate a magnetic field, driving the permanent magnet 31 to rotate, thereby driving the paddle 32 to slide. When the paddle 32 slides, the movable spring 42 abutting against the paddle 32 is deformed, causing the two contacts 43 to abut or separate.

[0031] Compared with the prior art, the utility model provides a three-phase relay without glue dispensing by setting the base 11 and the cover 12. The base 11 includes a coil part 111 for setting the coil assembly 20, a magnetic steel part 112 arranged on one side of the coil part 111 for setting the magnetic steel assembly 30, and an electrical connection part 113 arranged on both sides of the coil part 111 for setting the electrical connection assembly 40. The coil assembly 20, the magnetic steel assembly 30 and the electrical connection assembly 40 are exempted from the glue dispensing step when assembling, and the block 115 cooperates with the buckle 123, so that the combination effect is good, and the glue dispensing step when the base 11 and the cover 12 are combined is eliminated.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
