technical field

The utility model patent relates to a cable connector, in particular to a detachable cable connector with a temperature measuring function.

Background technique

The power lines transmitted by Dentsu in the power generation, transmission and distribution of power systems need to be realized through overhead lines or power cable lines. When connecting power cables to overhead lines or power equipment, they need to be connected through cable connectors. In the cable connection, the cable connector plays the role of insulation, sealing, and equalizing the uneven electric field at the joint.

In the power cable line, the position of the cable connector plays an important bridging role in the whole line. In the operation accident of the cable line, the operation accident is often caused by poor electrical contact or overload and overload current heating, which damages the cable connector, Cables, and even burnt connected electrical equipment, causing significant losses.

Therefore, temperature monitoring at the cable connection is particularly important. In this way, the problem can be found in the early stage of the fault, an early warning can be issued, and the fault can be eliminated in time.

Utility model content

The purpose of the utility model is to provide a detachable cable connector with temperature measuring function.

In order to achieve the above purpose, the utility model provides a detachable cable connector with a temperature measuring function, which includes an insulating body and a crimping terminal. The insulating body is in the shape of a "T"-shaped tube. The insulating body has two insertion holes and a mounting hole, wherein one insertion hole communicates horizontally with the installation hole, and the insertion hole and the installation hole communicate vertically with the other insertion hole. The crimp terminal has a connecting piece and a crimping tube connected to the connecting piece. The crimping tube is accommodated in the insertion hole perpendicular to the installation hole. A temperature sensor is arranged between the crimping tube and the inner wall of the insertion hole for accommodating the crimping tube.

Preferably, the temperature sensor is arranged on a PCB circuit board, and the PCB circuit board is accommodated between the crimping tube and the inner wall of the insertion hole for accommodating the crimping tube.

Preferably, the PCB circuit board is arranged on a collar, and the collar is placed on the crimping tube.

Preferably, a current sensor is arranged on the collar.

Preferably, the current sensor is an induction coil, and the induction coil is annularly arranged on the collar.

As mentioned above, the temperature sensor of a detachable cable connector with temperature measuring function in the present invention is arranged between the crimping tube and the inner wall of the insertion hole for accommodating the crimping tube. This structure enables the temperature sensor to directly press the Take over the tube to measure the temperature, and the crimping tube can directly reflect the temperature of the cable conductor. The temperature signal measured by the temperature sensor is transmitted to the outside world through a wired or wireless network. Therefore, the temperature measurement is more accurate, and the power line can be analyzed in real time according to the temperature of the cable conductor. Whether the system is running abnormally, and an alarm is issued according to the analysis results, so that the fault can be found and dealt with in time, so as to improve the reliability of power supply.
