Description

Technical Field

[0001] The utility model relates to the technical field of multi-core cable connector components, in particular to a multi-core cable connector component with a self-checking function. Background Art

[0002] Cable joints are also called cable heads. When the cable is laid, in order to make it a continuous line, each section of the line must be connected as a whole. These connection points are called cable joints. The cable joints in the middle of the cable line are called intermediate joints, and the cable joints at both ends of the line are called terminal heads. Cable joints are generally composed of a main body, clamping claws, tightening nuts and fixing nuts.

[0003] In this way, the cable is fixed by squeezing the clamping claws with the tightening nut. During the operation of the existing cable, heat is generated at the cable joint sheath. The continuous accumulation of heat will affect the cable and the cable joint, accelerate the aging speed, shorten their service life, and affect their use. When installing the cable joint, the fixing nut and the tightening nut need to be rotated and tightened, which makes the installation efficiency not high enough. For this reason, we propose a multi-core cable joint assembly with a self-test function. Utility Model Content

[0012] Beneficial Effects

[0013] The utility model provides a multi-core cable connector assembly with a self-checking function. It has the following beneficial effects:

[0014] (1) The multi-core cable connector assembly with a self-test function is matched by the internal components of the main body assembly and the connection assembly. The connection block is placed inside the circular groove of the electrical cabinet, and the matching block is pressed on the side of the connection block. The matching block squeezes the movable block to slide inside the movable groove. The movable block causes the support block to be squeezed and deformed until the matching block is pressed into place. The movable block is clamped and fixed on the side of the matching block under the deformation of the support block. In this way, the main body block is installed and fixed, and the cable is installed in the internal position of the main body block. The heat conduction block plays a heat conduction role for the cable. The airflow inside the electrical cabinet passes through the heat dissipation hole, and the airflow discharges the hot air through the heat conduction block. The detection block performs temperature detection on the cable connection. In this way, the cable and the cable connector have a certain heat dissipation and detection effect, which improves the use efficiency and facilitates the installation of the connector assembly on the side of the electrical cabinet.

[0015] (2) The multi-core cable connector assembly with a self-test function is fixed by the internal parts of the assembly. The movable cylinder is pressed on the side of the fixed block. The clamping block is squeezed and slides inside the installation groove to deform the elastic block. At the appropriate position, the clamping block is clamped inside the clamping groove under the deformation force of the elastic block to fix the movable cylinder. At the same time, the movable cylinder squeezes the fixed cylinder to deform and clamp it on the side of the cable. The pull rope pulls the elastic block to deform so that the clamping block is separated from the inside of the clamping groove, causing the movable cylinder to loosen and lose the squeezing of the fixed cylinder. This facilitates the fixation and removal of the cable. BRIEF DESCRIPTION OF THE DRAWINGS
