Description

Technical Field

[0001] The utility model relates to the technical field of thermal protectors, in particular to a snap-on thermal protector. Background Art

[0002] In many electrical equipment such as air conditioners and motors, thermal protectors are usually connected to their circuits. The thermal protectors can disconnect the circuit when it is overloaded, preventing the circuit from overheating and causing damage to electrical components or fire hazards.

[0003] Thermal protectors are usually installed inside the housing of an electrical appliance, and the installation space is very limited. The convex setting of the socket and the fixing socket will hinder the installation of the thermal protector, which is not conducive to the installation and use of the thermal protector. Moreover, the socket of the original device is an elastic clamping structure. Due to its easy deformation characteristics, the sealing and stability of the protector shell cannot be guaranteed after clamping, and the protection effect of the thermal protector is poor.

[0004] For this reason, a snap-on thermal protector is proposed, which is upgraded and modified on the basis of the device to solve these shortcomings. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the original device has an elastic snap-in structure, which is easy to deform and cannot ensure the sealing and stability of the protector shell after snap-in, resulting in poor protection effect on the thermal protector. The utility model provides a snap-in thermal protector.

[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0007] A snap-on thermal protector comprises a shell 1, wherein the outer end of the shell 1 abuts against a shell 2, the outer end of the shell 1 is fixedly connected to a connecting block 1, the outer end of the connecting block 1 is fixedly connected to a clamping block, the outer end of the shell 2 is provided with a connecting groove, the inner wall of the shell 2 is provided with a clamping groove for clamping the outer end of the clamping block, the lower side of the clamping groove is connected to the upper side of the inner wall of the connecting groove, the outer end of the shell 2 is provided with a disassembly mechanism, the inner walls of the shell 1 and the shell 2 are fixedly installed with conductors, and the outer ends of the conductors are fixedly installed with bimetallic strips.

[0008] Furthermore, a moving contact is fixedly installed on the outer end of the bimetallic strip, a static contact is fixedly installed on the outer end of the conductor, the outer end of the static contact abuts against the outer end of the moving contact, one end of the conductor abuts against an insulating block, one end of the insulating block is fixedly installed on the inner wall of the shell, and an installation cavity is opened inside the conductor.

[0009] Furthermore, a second connection block is fixedly mounted on one end of the conductor, and a wire clamping groove is fixedly connected to one end of the second connection block.

[0010] Furthermore, the outer ends of the shell one and the shell two are fixedly connected with sealing blocks, the outer ends of the shell one and the shell two are provided with sealing grooves for matching the outer ends of the sealing blocks, and a sealing ring is installed at the connection between the shell one and the shell two.

[0011] Furthermore, the disassembly mechanism includes a button, the inner wall of the shell 2 is slidably connected with the button, one end of the button is fixedly connected with a stopper, the outer end of the stopper is fixedly installed with a push block, and the push block is directly above the card slot.

[0012] Furthermore, a spring is fixedly mounted on the outer end of the stopper, and one end of the spring is fixedly mounted on the inner wall of the second housing.

[0013] The beneficial effects of the utility model are as follows:

[0014] The utility model has a structure in which a mounting cavity is arranged on the conductor and the bimetallic strip is hidden in the mounting cavity, so that the bimetallic strip will not be disturbed by external objects during operation, thereby ensuring the working stability of the thermal protector.

[0015] The utility model disassembles the connection block into the interior of the connection groove so that the clamping block and the clamping groove are clamped, which facilitates the mutual connection of the shell one and the shell two. The connection block and the connection groove are embedded in the interior of the shell and will not affect the installation of the thermal protector, which can be beneficial to the installation and use of the thermal protector. After being fixed, the shells will not loosen, which can ensure the sealing effect of the shells. The sealing block, the sealing groove and the sealing ring can be used to provide good sealing protection for the thermal protector.

[0016] The utility model presses a button to make the push block enter the interior of the card slot, and pushes the card block into the connecting slot, so as to separate the first shell from the second shell. The button returns to its original position through the action of a spring, so as to reconnect the first shell with the second shell. BRIEF DESCRIPTION OF THE DRAWINGS
