Description

Technical Field

[0001] The utility model belongs to the technical field of relays, and in particular relates to a relay which is easy to install. Background Art

[0002] A relay is an electrical control device. When the change of input quantity reaches the specified requirements, it causes the controlled quantity to undergo a predetermined step change in the electrical output circuit. It has an interactive relationship between the control system and the controlled system. It is usually used in automated control circuits. It is actually an "automatic switch" that uses a small current to control the operation of a large current; therefore, it plays the role of automatic adjustment, safety protection, and circuit conversion in the circuit. At present, the soft starter will trip from time to time, and a relay needs to be installed for use. However, the wires of the traditional relay installation are messy, resulting in the wires of other electrical components in the control cabinet being entangled together, which is not only inconvenient for maintenance, but also causes short circuits; at the same time, after the relay is installed in the control cabinet, the heat dissipation cannot be controlled, resulting in the relay not being able to reach the optimal operating state, increasing energy consumption.

[0003] The Chinese utility model patent with publication number CN220253134U discloses a relay installation structure. By setting a mounting plate and a wire tube, it is convenient to install the relay, and the wires inside the control cabinet are rationally arranged to facilitate maintenance and prevent short circuits. When used in conjunction with wire clamps, the internal wires can move with the mounting plate to avoid breaking. At the same time, by opening the blocking plate, the internal heat is discharged from the heat dissipation window to reduce the temperature in the control cabinet, which is convenient for the relay to continue to work normally. However, the device still has some other problems. For example, the relay of the device is fixed to the mounting plate by bolts, which makes disassembly and installation more troublesome.

[0039] The relay body 300 is fixed on one side of the fixing device 200;

[0040] A protective cover, hinged to the mounting base 100 via a rotating shaft;

[0041] Wherein, the fixing device 200 comprises:

[0042] Fixed frame 210;

[0043] Through holes 220 are provided on both sides of the fixing frame 210;

[0044] The slide groove 230 is disposed on the surface of the fixing frame 210 and communicates with the through hole 220;

[0046] A spring 250 is disposed at one end of the control rod 240;

[0047] A connecting rod 260 passes through the slide slot 230 and is laterally disposed on the control rod 240;

[0048] The fixing block 270 is disposed below the connecting rod 260 .

[0049] In the present technical solution, in order to facilitate the installation of the relay body 300, a mounting base 100 is provided for this purpose. The relay body 300 is installed on the mounting base 100 through the fixing device 200. At this time, through holes 220 are respectively opened on the left and right sides of the fixing frame 210 of the fixing device 200, and a slide groove 230 is opened on the upper surface of the through hole 220.

[0050] Embodiment 2:

[0051] This embodiment provides a relay that is easy to install. In addition to the technical solutions of the above embodiments, it also has the following technical features.

[0052] like Figure 4 As shown, in this embodiment, a stopper is disposed on the periphery of the control rod 240 , and a groove cooperating with the stopper is disposed inside the through hole 220 .

[0053] In the present technical solution, in order to prevent the control rod 240 from slipping out of the through hole 220, a stopper is provided on the outer wall of the control rod 240 near the through hole 220 when the spring 250 inside the channel is relaxed, and a groove is provided at a position corresponding to the stopper of the control rod 240. The length of the groove extends to the place where the stopper can reach when the spring 250 is fully compressed, so that the control rod 240 can always be inside the through hole 220.

[0054] Embodiment 3:

[0055] This embodiment provides a relay that is easy to install. In addition to the technical solutions of the above embodiments, it also has the following technical features.

[0056] like Figure 4 As shown, in this embodiment, two control rods 240 are placed inside the through hole 220 , and ends of the two control rods 240 close to each other are fixedly connected to two ends of the spring 250 .

[0057] In the present technical solution, in order to facilitate the control of the position of the control rod 240, two control rods 240 are arranged inside each through hole 220, and the ends of the two control rods 240 close to each other are connected to the two ends of the spring 250, so that pressing the control rod 240 inside the through hole 220 can change the position of the control rod 240 inside the through hole 220.

[0061] In the present technical solution, in order to facilitate the pressing of the control rod 240, the length of the two control rods 240 plus the spring 250 inside the through hole 220 is greater than the length of the through hole 220. When the spring 250 is fully compressed, the length of the two control rods 240 plus the spring 250 when compressed is also greater than the length of the through hole 220. This makes it convenient for the staff to control the control rod 240.

[0069] In the present technical solution, in order to be able to fix the fixing device 200 on the mounting base 100, a mounting groove 122 is opened on the upper surface of the mounting base 100. The mounting groove 122 facilitates the connecting rod 260 and the fixing block 270 to slide inside the mounting groove 122, and the positions of the connecting rod 260 and the fixing block 270 inside the mounting base 100 are never changed. At the same time, a fixing groove 123 is also provided inside the mounting groove 122. The fixing groove 123 matches the shape of the fixing block 270, so that when the fixing block 270 slides to the corresponding position along the mounting groove 122, the fixing block 270 can be fixed, thereby fixing the fixing device 200 and the mounting base 100 together.
