[0002] Terminal blocks are an accessory product used to achieve electrical connections. They are classified as connectors in the industry. With the increasing degree of industrial automation and the increasingly stringent and precise requirements for industrial control, the use of terminal blocks has gradually increased. With the development of the electronics industry, the use of terminal blocks has become more and more extensive, and there are more and more types. In addition to PCB board terminals, the most widely used ones are hardware terminals, nut terminals, spring terminals, etc. Terminal blocks can be divided into: European terminal block series, plug-in terminal block series, transformer terminal blocks, building wiring terminals, fence terminal block series, spring terminal block series, track terminal block series, through-the-wall terminal block series, photoelectric coupling terminal block series, Ring terminal flag series terminals and sheath series, various types of ring terminals, tubular terminals, wiring terminals, copper strips and iron strips, etc. Among the wiring terminal sheath series, heat shrinkable wiring terminals are often used because of their small space occupation and low cost. Heat shrinkable wiring terminals are a special polyolefin heat shrinkable sleeve. The outer layer is made of high-quality soft cross-linked polyolefin material, and the inner layer is made of hot melt adhesive. The outer layer material has the characteristics of insulation, corrosion resistance, wear resistance, etc., and the inner layer has the advantages of low melting point, waterproof sealing and high adhesion. However, the existing heat shrinkable wiring terminals have poor performance, and are mostly heated and installed manually by staff.

Rotary connectors (914) are arranged on both the front and rear sides of the bottom ends of the outer walls of the two front and rear U-shaped nozzle pipes (913). The rotary connectors (914) and the controller (7) are electrically connected. The lower rotating ends of the two left and right groups of rotary connectors (914) are both provided with bottom nozzle pipes (915); Step 2: Cut the wiring heat shrink component into blocks and open the top cover (6), place the wiring heat shrink component cut into blocks on the inner side of the semi-circular plate (17) in the left and right installation mechanisms, and pass the damaged ends of the cable through the left and right limit grooves (10) respectively and place them on the inner side of the clamps (12) in the left and right fixing mechanisms, then close the top cover (6), start the controller (7), and the pre-programmed controller (7) controls the electric push rod (13), the second electric telescopic rod (18), and the rotary connector (914) ), the micro motor (94) and the hot air blower (8) are started in sequence, the electric push rods (13) in the fixing mechanisms on the left and right sides are extended to push the clamp (12) to move inward under the limiting action of the limiting guide rail (11) to clamp and fix the cable, and the second electric telescopic rods (18) in the mounting mechanisms on the left and right sides are shortened to drive the upper semi-annular plate (17) at the corresponding position to rotate inward with the pin shaft connection with the lifting seat (16) as the vertex, so that the semi-annular plate (17) wraps the wiring block heat shrink component around the outside of the cable; Step 3: The first electric telescopic rod (15) is extended to push the lifting seat (16) upward, so that the lifting seat (16) lifts the bottom of the cable to a sufficient gap in cooperation with the semi-circular plate (17), and the rotary connector (914) drives the bottom nozzle tube (915) to rotate inward, so that the bottom nozzle tube (915) penetrates into the gap below the cable, and the micro motor (94) drives the universal transmission shaft (92) to rotate intermittently clockwise or counterclockwise, so that the universal transmission shaft (92) drives one end of the spur gear set (93) at the corresponding position on the front and rear sides to rotate, and under the transmission of the spur gear set (93) itself, the front and rear two rotating disks (95) are driven to intermittently move one end of the connecting rod (912) inward or outward in cooperation with the adjusting screw (97), so that the connecting rod (912) is moved inward or outward. The connection seat (911) cooperates with the lower driving limit plug rod (99) to move inward or outward, so that the limit plug rod (99) is limited by the slot seat (98) at the corresponding position, prompting the limit plug rods (99) on both sides to respectively drive the U-shaped nozzle tube (913) arranged on the outside of the cable to move inside and outside, and the U-shaped nozzle tube (913) drives the bottom nozzle tube (915) to move synchronously inside and outside under the cable in cooperation with the rotary connector (914). The hot air blower (8) discharges the internal hot air from the duct into the U-shaped nozzle tube (913) and the bottom nozzle tube (915) and sprays it to the outside of the cable, so that the wiring heat shrink component on the outside of the cable is heated to a semi-molten state and adheres to the outside of the cable, thereby protecting the outside of the damaged or broken end of the cable, and the cable is taken out after cooling.

2. The method for installing a high-performance terminal block according to claim 1, characterized in that: The two front and rear limit blocks (96) are symmetrically arranged.

3. The method for installing a high-performance terminal block according to claim 2, characterized in that: The inner cavities of the U-shaped nozzle tube (913) and the bottom nozzle tube (915) are in communication.
