Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-5 The present invention provides a cable elbow head wireless temperature measuring device, comprising an elbow-shaped cable joint housing 101, a cable body 102 is installed on the elbow-shaped cable joint housing 101, a copper terminal 103 is fixed to one end of the cable body 102 located inside the elbow-shaped cable joint housing 101, and further comprising:

[0026] The rear plug 2 is detachably mounted on the rear portion of the elbow-type cable connector housing 101 by means of threads, and the rear plug 2 is provided with a detection component for post-installation temperature detection and a transmission component for post-detection information transmission;

[0027] It should be noted here that:

[0028] The detection component includes a mounting plate 301 arranged at the front side of the rear plug 2, an elastic component for assisting the elastic connection of the mounting plate 301 is arranged between the mounting plate 301 and the rear plug 2, and a temperature sensor 302 for abutting against the copper terminal 103 for temperature detection is installed on the mounting plate 301;

[0029] It should be noted here that: during the temperature measuring device measuring the temperature of the elbow-type cable connector, it can not only push the temperature sensor 302 on the mounting plate 301 through transmission to always keep it against the copper terminal 103 during the temperature measurement process to ensure the accuracy of the temperature measurement process, but also supply power through a passive power sensor to realize wireless detection and transmission operations, thereby facilitating the safe collection and transmission of temperature measurement data.

[0030] The elastic component includes a mounting groove 401 provided at the front end of the rear plug 2, and a plurality of connecting springs 404 are connected between the interior of the mounting groove 401 and the mounting plate 301. The rear plug 2 is provided with an adjusting component for adjusting the elastic force of the elastic component and a guiding component for guiding during the adjustment process;

[0031] It should be noted here that: during the installation of the rear plug 2, the front end of the temperature sensor 302 on the mounting disk 301 is abutted against the copper terminal 103, and as the rear plug 2 continues to be screwed in for installation, each group of connecting springs 404 is deformed by force to generate elastic force. Through the elastic force of the connecting springs 404, the temperature sensor 302 on the mounting disk 301 is pushed to always remain against the copper terminal 103 during the temperature measurement process, thereby ensuring the accuracy of the temperature measurement process.

[0032] A plurality of sleeves 402 are arranged inside the installation groove 401, and each group of connecting springs 404 is respectively sleeved on the outside of each group of sleeves 402. A slide rod 403 is slidably connected to the sleeve 402, and one end of the slide rod 403 is fixed to the installation plate 301;

[0033] It should be noted here that the sleeve 402 and the slide rod 403 facilitate the stable extension and retraction of the auxiliary mounting plate 301 .

[0034] The adjusting assembly includes an annular plate 701 arranged inside the mounting groove 401, one end of each set of sleeves 402 is fixed to the annular plate 701, a support frame 702 is fixed inside the rear plug 2, a threaded rod 703 is rotatably connected to the support frame 702, a threaded tube 704 is threadedly engaged and connected to the threaded rod 703, one end of the threaded tube 704 is fixed to the annular plate 701, and a driving pin 705 is fixed to the other end of the threaded rod 703; the guiding assembly includes a plurality of sets of mounting cylinders 801 fixed to the annular plate 701, a round rod 802 is slidably connected to the mounting cylinder 801, and one end of the round rod 802 is fixed to the supporting frame 702;

During the movement of the annular plate 701, the elastic force of each group of connecting springs 404 is adjusted, so that the temperature sensor 302 can be offset against the copper terminal 103 with different elastic forces, so that the temperature measurement process can be more flexible to operate and use.

[0036] The transmission component includes a connection slot 501 provided at the rear end of the rear plug 2, and a wireless transmitter 502 is detachably mounted on the connection slot 501 by means of threads;

[0037] It should be noted here that the temperature sensor 302 transmits the information obtained after temperature measurement to the wireless transmitter 502 by wireless transmission, and the wireless transmitter 502 then transmits the obtained information to the remote processor by wireless transmission and displays it on the display, thereby realizing the transmission of information after temperature measurement.

[0038] A passive power sensor for passive wireless power supply is installed inside the wireless transmitter 502 and the temperature sensor 302;

[0039] It should be noted here that: after the wireless transmitter 502 and the temperature sensor 302 are installed, the electric energy is obtained and the power is supplied through the electromagnetic interaction between the internal passive power sensor and the cable body 102;

[0040] It is worth noting here that a passive power sensor is a sensor that does not require an external power supply and works by obtaining energy from the environment. It uses scattered energy such as light energy, temperature difference conversion, vibration energy, etc. in the environment, and converts these energies into electrical energy through specific energy conversion mechanisms such as electromagnetic induction and piezoelectric effect, etc., to power the sensor itself. This type of sensor has the advantages of energy saving and environmental protection, high reliability, and a wide range of applications. Passive power sensors are used as prior art in this application and will not be elaborated on here.

[0044] It should be noted here that: during the temperature measuring device measuring the temperature of the elbow type cable connector, the rear plug 2 is installed on the tail of the elbow type cable connector housing 101 by means of threads. During the installation process, the positioning ring 6 is abutted against the tail of the elbow type cable connector housing 101 to position the rear plug 2 during the installation process.

During the installation process, the positioning ring 6 is abutted against the tail of the elbow-type cable connector housing 101 to position the rear plug 2 during the installation process;

[0046] During the installation of the rear plug 2, the front end of the temperature sensor 302 on the mounting plate 301 is abutted against the copper terminal 103, and as the rear plug 2 continues to be screwed in for installation, each group of connecting springs 404 is deformed by force to generate elastic force, and the temperature sensor 302 on the mounting plate 301 is pushed to always be against the copper terminal 103 during the temperature measurement process through the elastic force of the connecting spring 404, so as to ensure the accuracy of the temperature measurement process, and during the process of the elastic force pushing, the annular plate 701 is moved by adjusting the assembly and the guide assembly, and during the movement of the annular plate 701, the elastic force of each group of connecting springs 404 is adjusted, so that the temperature sensor 302 can be abutted against the copper terminal 103 with different elastic forces, so that the temperature measurement process can be more flexibly operated and used;

[0047] During the temperature measurement and transmission process, the temperature sensor 302 transmits the information obtained after the temperature measurement to the wireless transmitter 502 by wireless transmission. The wireless transmitter 502 then transmits the obtained information to the remote processor by wireless transmission and displays it through the display, thereby realizing the transmission of information after temperature measurement. During the entire temperature measurement and transmission process, the temperature sensor 302 and the wireless transmitter 502 are both powered by passive power sensors, realizing detection and transmission operations in wireless conditions, and facilitating the safe collection and transmission of temperature measurement data.
