Description

Technical Field

[0001] The utility model relates to the technical field of relays, in particular to a novel thermal overload relay. Background Art

[0002] A thermal overload relay, also known as a thermal relay, is an overload relay that applies the principle of current thermal effect and uses an electrical thermosensitive bimetallic sheet as a sensitive element. The heating element of the thermal overload relay is directly or connected to the motor circuit through a current transformer. When the motor is overloaded, the main bimetallic sheet is heated to the operating temperature, causing the relay to operate and disconnect the power circuit of the motor, so that the motor is protected from damage due to overload.

[0003] When installing a thermal overload relay, the thermal overload relay is fixed to the installation location through connection bolts. However, in the prior art, the thermal overload relay does not have a guiding and fixing function, so that during the process of tightening the connection bolts during the installation of the thermal overload relay, the thermal overload relay is likely to be driven to shift in position or the installation direction is incorrect. Summary of the Invention

[0004] The purpose of the utility model is to provide a novel thermal overload relay to solve the problem that when installing a thermal overload relay, the thermal overload relay is fixed to the installation location through connection bolts. However, in the prior art, the thermal overload relay does not have a guiding and fixing function, so that during the process of tightening the connection bolts during the installation of the thermal overload relay, the thermal overload relay is likely to be driven to shift in position or the installation direction is incorrect.

An installation platform is provided on the front end face of the relay body. Guide blocks are fixedly installed on both sides of the surface of the installation platform. A connection block is fixedly installed between the two guide blocks on the surface of the installation platform. A plug block is fixedly connected to the lower position of the rear end face of the relay body. A plurality of limiting grooves are respectively provided at the front and rear positions on the bottom surface of the relay body.

[0006] Preferably, one end of the guide block is an installation end connected to the installation platform. The installation end extends horizontally outward to form a bending part. The bending part continues to extend downward to form a plug end.

[0007] Preferably, the installation end and the plug end are designed in a Z-shaped structure.

[0008] Preferably, a connection hole is provided on the surface of the connection block.

[0009] Preferably, an avoidance opening is provided on the surface of the plug block.

[0010] Preferably, a guiding opening is formed at the bottom of the plug end, and the guiding opening is designed in an arc shape.

[0018] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", "vertical", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0020] Such as Figures 1-3It is a schematic structural diagram of a new type of thermal overload relay according to a preferred embodiment of the present invention. In this embodiment, a new type of thermal overload relay includes a relay body 1. An installation platform 2 is provided on the front end face of the relay body 1. Guide blocks 3 are fixedly installed on both sides of the surface of the installation platform 2, which play a role in guiding the installation of the relay body 1 during the installation process. A connection block 4 is fixedly installed on the surface of the installation platform 2 between the two guide blocks 3. A connection hole 5 is provided on the surface of the connection block 4, which is used to fix the relay body 1 after installation. The lower position of the rear end face of the relay body 1 is fixedly connected with a plug block 7. Through the cooperation between the plug block 7 and the guide block 3, the relay body 1 will not be displaced or installed in the wrong direction during installation and fixation. A plurality of limit grooves 6 are respectively provided at the front end and the rear end of the bottom surface of the relay body 1. The design of the limit grooves 6 assists the plug block 7 and the guide block 3 to further ensure the stability of the relay body 1 during installation and fixation.

[0021] In this embodiment, one end of the guide block 3 is an installation end 31 connected to the installation platform 2. The installation end 31 extends horizontally outward to form a bending part 32, and the bending part 32 continues to extend downward to form a plug end 33. The installation end 31 and the plug end 33 are designed in a Z-shaped structure. This structural design plays a role in avoiding other installation components during the installation process and also prevents the bending part 32 from being bent relative to the plug end 33.

[0022] In this embodiment, an avoidance opening 8 is provided on the surface of the plug block 7 to facilitate the plug block 7 to be plugged and connected to the installation location better.

[0023] In this embodiment, a guide opening 34 is provided at the bottom of the plug end 33, and the guide opening 34 is designed in an arc shape. This structural design facilitates the better guiding connection of the guide block 3 and effectively prevents the resistance that occurs during the insertion of the guide block 3.
