It is usually used in automatic control circuits. It is actually an "automatic switch" that uses a smaller current and a lower voltage to control a larger current and a higher voltage. Therefore, it plays the role of automatic adjustment, safety protection, and circuit conversion in the circuit.

[0003] After installation, existing electromagnetic relays are difficult to disassemble for maintenance or replacement, resulting in high labor intensity for workers. In addition, after being fixed, existing electromagnetic relays are difficult to adjust the angle and have poor flexibility. Therefore, the present invention proposes a low-temperature rise small electromagnetic relay to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0022] Please refer to Figure 1-4 The application provides a technical solution: a low-temperature-rise small electromagnetic relay, comprising an electromagnetic relay body 1, a placing frame 2 and a fixed plate 3 fixed on a device shell through a bolt 4, and a wiring pin is arranged at the top of the electromagnetic relay body 1, characterized in that: an angle adjusting assembly 5 is arranged between the bottom of the placing frame 2 and the top of the fixed plate 3, and clamping assemblies 6 are arranged on both sides of the placing frame 2.

[0023] The clamping assembly 6 comprises left and right two movable frames 61 which are slidably connected to the bottom of the inner wall of the placing frame 2 through slide rails, and support assemblies 62 are arranged at the bottom of the inner wall of each of the two movable frames 61, the top and the bottom of the side away from each other of the two movable frames 61 are fixedly connected with movable rods 63, one end of the movable rod 63 away from the movable frame 61 penetrates to the outside of the placing frame 2, the end of the movable rod 63 located outside the placing frame 2 is fixedly connected with a connecting plate 64, and the side of the connecting plate 64 away from the movable rod 63 is fixedly connected with a handle 65, a first spring 66 is fixedly connected to the outer side wall of the movable frame 61 and sheathed on the surface of the movable rod 63, and one end of the first spring 66 away from the movable frame 61 is fixedly connected to one side of the inner wall of the placing frame 2.

[0024] The support assembly 62 comprises a second spring 621 fixed to the inner wall bottom of the movable frame 61, and the top end of the second spring 621 is fixedly connected with a support plate 622, the electromagnetic relay body 1 is clamped between the two movable frames 61, and the bottom is in abutment with the top of the support plate 622.

[0025] The angle adjustment assembly 5 includes an annular plate 51 fixed to the top of the fixed plate 3 and a rotating plate 52 rotatably connected to the top of the fixed plate 3 through a turntable. The rotating plate 52 is located inside the annular plate 51. The top of the rotating plate 52 is fixedly connected to a third spring 53, and the top of the third spring 53 is fixedly connected to the bottom of the placement frame 2. Both sides of the bottom of the placement frame 2 are fixedly connected with a clamping block 54, and the top of the annular plate 51 is provided with a clamping groove 55 adapted to the clamping block 54.

[0026] When the electromagnetic relay body 1 needs to be disassembled for replacement or repair, the handles 65 on both sides are pulled away from the placement frame 2, and the movable rod 63 is driven to move through the connecting plate 64, and the two movable frames 61 are further driven to move away from each other. When the top of the electromagnetic relay body 1 is away from the top of the movable frame 61, it will automatically pop out of the movable frame 61 under the action of the rebound force of the second spring 621 at the bottom, and then the electromagnetic relay body 1 can be taken out. When installing, pull the two handles 65 again to move the two movable frames 61 away from each other, and then place the electromagnetic relay body 1 between the two movable frames 61 and press down so that the two support plates 622 compress the second spring 621. After the electromagnetic relay body 1 completely enters the movable frame 61, release the handles 65 on both sides so that the two movable frames 61 fix the electromagnetic relay body 1 in the placement frame 2.

[0027] When the angle of the electromagnetic relay body 1 needs to be adjusted for wiring convenience, the handle 65 is lifted upward, and then the placement frame 2 is lifted upward, further driving the clamping block 54 to disengage from the clamping slot 55, and the third spring 53 is stretched. Then the handle 65 is rotated to drive the placement frame 2 to rotate, and the angle of the electromagnetic relay body 1 can be adjusted. Then, the placement frame 2 is pressed down to re-engage the clamping block 54 in the corresponding clamping slot 55 to fix it.
