Description

Technical Field

[0001] The utility model relates to the technical field of power plugs, in particular to a power plug with a temperature control function. Background Art

[0002] A power plug is an electronic component used for circuit connection, also called a terminal block, an electrical connector, etc. An electrical connector consists of a fixed-end electrical connector (socket) and a free-end electrical connector (plug). The socket is fixed on the electrical component through its square (round) plate (in some cases, welding is also used). The plug is generally connected to a cable, and the connection between the plug and the socket is achieved through a connecting nut. A power plug not only includes terminals for external plugging, but also includes a power cord for external power connection and a signal line for signal transmission.

[0003] Power plugs are mostly used in some power tools. Generally, they include signal terminals for transmitting signals and power terminals for connecting to an external power supply. When some power tools with larger power are working, a relatively large current is required, so the temperature of the power terminals in the power plug gradually increases with the change of working time. The existing power plugs can only connect the current and cannot monitor the temperature of the power terminals in the power plug in real time, so that users cannot observe the working state of the power plug at any time, which is not convenient for the user's use process, and it is easy to continue using when the power terminals are overheated, avoiding damage to the power plug due to overheating of the power terminals. Therefore, it is necessary to further improve the structure of the existing power plug. Content of the Utility Model

[0004] In view of this, in view of the deficiencies of the existing technology, the main purpose of the utility model is to provide a power plug with a temperature control function, which can effectively solve the problems that the existing power plug cannot detect the working temperature of the terminals, is not convenient for the user's use process, and is easy to damage the power plug.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A power plug with a temperature control function includes an insulating body, signal terminals, power terminals, and a temperature sensor. There are two signal terminals, both of which are embedded in the insulating body. Each signal terminal includes an integrally formed first main body portion, a first plugging portion, and a first connecting portion. The first main body portion and the first connecting portion are embedded in the insulating body. The first connecting portion is connected to an external first wire, and the first plugging portion extends out of the insulating body. There are two power terminals, both of which are embedded in the insulating body. Each power terminal includes an integrally formed second main body portion, a second plugging portion, a second connecting portion, and a contact portion. The second main body portion, the second connecting portion, and the contact portion are all embedded in the insulating body. The second connecting portion is connected to an external second wire. The second plugging portion extends out of the insulating body. The temperature sensor is arranged on the insulating body and contacts the contact portion.

[0007] As a preferred solution, an installation member is arranged on the insulating body. Positioning grooves are horizontally and spacedly arranged on the installation member. A first positioning portion that cooperates with the positioning groove is arranged on each signal terminal, and a second positioning portion that cooperates with the positioning groove is arranged on each power terminal.

[0008] As a preferred solution, a first guiding portion is arranged on the outer side wall of the first plugging portion, and a second guiding portion is arranged on the outer side wall of the second plugging portion.

[0009] As a preferred solution, first anti-slip surfaces are respectively arranged on both side walls of the first plugging portion, and second anti-slip surfaces are respectively arranged on both side walls of the second plugging portion.

[0010] As a preferred solution, an installation portion integrally extends upward from the upper surface of the contact portion. An installation groove with an open upper end is provided in the installation portion. The lower end of the temperature sensor extends inward into the installation groove.

[0011] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions:

[0012] Each power terminal includes an integrally formed second main body portion, a second plugging portion, a second connecting portion, and a contact portion, and is combined with the temperature sensor arranged on the insulating body and contacting the contact portion, so that during the working process, the temperature of the power terminal can be monitored in real time through the contact between the temperature sensor and the contact portion, and the temperature situation can be transmitted in time through the temperature sensor, thus facilitating the user to observe the working state of the power plug and facilitating the user's use process. When the temperature is too high, the user can be notified in time to avoid continuing to use when the temperature is too high and damaging the power plug.

[0030] Please refer to Figures 1 to 2 as shown, which shows the specific structure of a preferred embodiment of the present utility model, including an insulating body 10, signal terminals 20, power supply terminals 30, and a temperature sensor 40.

[0031] Two signal terminals 20 are provided. Both signal terminals 20 are embedded in the insulating body 10. Each signal terminal 20 includes an integrally formed first main body portion 21, a first insertion portion 22, and a first connecting portion 23; the first main body portion 21 and the first connecting portion 23 are embedded in the insulating body 10, the first connecting portion 23 is connected to an external first wire 50, and the first insertion portion 22 extends out of the insulating body 10.

[0032] In this embodiment, a mounting member 11 is provided on the insulating body 10. Positioning grooves 101 are horizontally and spacedly arranged on the mounting member 11; a first positioning portion 24 cooperating with the positioning groove 101 is provided on each signal terminal 20. Through the cooperation of the first positioning portion 24 and the positioning groove 101, when assembling, the signal terminal 20 can be first positioned and mounted on the mounting member 11, and then subsequent injection molding processing can be carried out, which is more convenient for the injection molding process; a first guiding portion 221 is provided on the outer side wall of the first plugging portion 22, thus facilitating the plugging process between the signal terminal 20 and the outside. First anti-slip surfaces 222 are respectively provided on both side walls of the first plugging portion 22. The first anti-slip surfaces 222 can not only prevent falling off from the outside after plugging, but also scrape off the rust generated on the external contact portion, ensuring the stability of the signal transmission process.

[0033] Two power terminals 30 are provided. Both power terminals 30 are embedded in the insulating body 10. Each power terminal 30 includes an integrally formed second main body portion 31, a second plugging portion 32, a second connecting portion 33, and a contact portion 34; the second main body portion 31, the second connecting portion 33, and the contact portion 34 are all embedded in the insulating body 10, and the second connecting portion 33 is connected to an external second wire 60; the second plugging portion 32 extends out of the insulating body 10; in this embodiment, a second positioning portion 35 cooperating with the positioning groove 101 is provided on each power terminal 30, so that during the installation process, the power terminal 30 can be first positioned and mounted on the mounting member 11 through the cooperation of the positioning groove 101 and the second positioning portion 35, thus facilitating subsequent injection molding processing. A second guiding portion 321 is provided on the outer side wall of the second plugging portion 32, and the second guiding portion 321 facilitates the plugging process between the power terminal 30 and the outside. Second anti-slip surfaces 322 are respectively provided on both side walls of the second plugging portion 32.
