DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 As shown, the utility model provides a thermistor mounting device, including a thermistor body 3, a connecting plate 2 is fixedly connected to the lower surface of the thermistor body 3, a mounting plate 1 is arranged at the bottom of the connecting plate 2, a rectangular array of mounting holes communicating with each other are opened on the upper surface of the mounting plate 1, a connecting assembly 4 is mirror-imaged at the middle of the front and rear sides of the connecting plate 2, and a wire is fixedly connected to the middle of the left and right sides of the thermistor body 3;

[0027] The connection assembly 4 is provided to facilitate the connection between the mounting plate 1, the connection plate 2 and the thermistor body 3, and the mounting holes in the mounting plate 1 are provided to facilitate the installation and connection of the screws.

[0028] like Figure 2 As shown, the connection assembly 4 includes a positioning plate 41 and a fixing plate 43. The lower surface of the positioning plate 41 is fixedly connected to the upper surface of the mounting plate 1, and the lower surface of the fixing plate 43 is fixedly connected to the upper surface of the connecting plate 2. A plurality of front-to-back connected sockets 42 are provided above the front of the positioning plate 41, and connecting blocks are formed between the plurality of sockets 42. An elastic plate 44 is fixedly connected to the front side of the fixing plate 43, and a plurality of upper-to-lower connected grooves 45 are provided on the front of the elastic plate 44, and plug blocks are formed between the plurality of grooves 45. The plurality of plug blocks are plugged into the interior of the plurality of sockets 42, and the height of the positioning plate 41 is greater than the height of the fixing plate 43.

[0029] When installation is required, the elastic plates 44 in the front and rear sides of the connecting plate 2 are squeezed and bent, thereby deforming. Then, the connecting plate 2 is driven by moving the thermistor body 3 downward to contact the mounting plate 1, so that the outer surface of the elastic plate 44 contacts the positioning plate 41. Then, the elastic plate 44 is loosened to insert the plug formed in the elastic plate 44 into the inside of the socket 42. At this time, the elastic plate 44 returns to a normal horizontal state, thereby facilitating connection and installation. When disassembly is required, the thermistor body 3 is directly pulled out with force to cause the elastic plate 44 to deform and shrink, thereby completing the separation effect.

[0030] like Figure 3 - Figure 4As shown, a placement opening 11 is provided on the upper surface of the mounting plate 1, and openings 12 communicating with each other are provided in the middle of the left and right sides of the placement opening 11, and four positioning columns 13 are fixedly connected in a rectangular array on the lower surface of the inner wall of the placement opening 11, and a protective component 14 is overlapped inside the placement opening 11, and the shape of the protective component 14 is smaller than the shape of the placement opening 11, and four circular holes 15 communicating with each other from top to bottom are provided in a rectangular array on the upper surface of the protective component 14, and the inside of the four circular holes 15 is plugged with the outer surfaces of the four positioning columns 13, and the material of the four positioning columns 13 is rubber, the outer surface of the connecting plate 2 is overlapped with the inside of the placement opening 11, and the shape of the connecting plate 2 is the same as that of the placement opening 11, and a placement groove 21 communicating with each other from top to bottom is provided on the lower surface of the connecting plate 2, and the inside of the placement groove 21 is overlapped with the outer surface of the protective component 14, and the lower surface of the thermistor body 3 is fixedly connected with the upper surface of the protective component 14;

[0031] The placement groove 21 is provided to facilitate fixing of the protective component 14. When the thermistor body 3 is installed, the connecting plate 2 is inserted into the placement opening 11. At this time, the circular hole 15 in the protective component 14 slides on the outer surface of the positioning column 13. When it moves downward to an appropriate position, the lower surface of the protective component 14 contacts the upper surface of the inner wall of the placement opening 11. Since the positioning column 13 contacts and deforms the circular hole 15 to make a tight fit, the limiting effect is enhanced. At this time, the thermistor body 3 can be quickly and accurately positioned when installed. The through hole 12 is provided to facilitate the flow of air inside the placement opening 11, which has a certain degree of heat dissipation effect.

[0032] like Figure 5 As shown, the protection component 14 includes two insulating plates 141, two heat-resistant rubbers 142 are arranged on opposite sides of the two insulating plates 141, and elastic rubbers 143 are arranged on opposite sides of the two heat-resistant rubbers 142. The insulating plates 141, the heat-resistant rubbers 142, and the elastic rubbers 143 are connected and fixed by glue;

[0033] The insulating plate 141 is provided to prevent other components from leaking electricity, thereby preventing the thermistor body 3 from being damaged. The heat-resistant rubber 142 and the elastic rubber 143 are provided to provide buffer protection for the thermistor body 3, thereby improving the service life of the thermistor body 3.

[0034] The following is a detailed description of the working principle of the thermistor mounted device.

[0035] By squeezing and bending the elastic plate 44 to deform it, and then moving the thermistor body 3 downward to drive the connecting plate 2 to contact the mounting plate 1, so that the outer surface of the elastic plate 44 contacts the positioning plate 41, and then the elastic plate 44 is loosened to allow the plug formed in the elastic plate 44 to be inserted into the inside of the socket 42. At this time, the elastic plate 44 returns to its normal horizontal state, which is convenient for connection and installation. When the thermistor body 3 is installed, the connecting plate 2 is inserted into the inside of the placement port 11. At this time, the circular hole 15 in the protective component 14 slides on the outer surface of the positioning column 13. When it moves downward to an appropriate position, the lower surface of the protective component 14 contacts the upper surface of the inner wall of the placement port 11. Since the positioning column 13 contacts the circular hole 15 and deforms, they fit tightly, thereby enhancing the limiting effect. At this time, the thermistor body 3 can be quickly and accurately positioned when installed.

[0036] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
