DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-3 As shown, a power terminal suitable for a copper busbar in a power distribution cabinet comprises a copper busbar 1 and a terminal body 2. The copper busbar 1 is provided with a plurality of assembly holes 101. The terminal body 2 is fixedly installed in the assembly holes 101. The terminal body 2 comprises a sleeve 21, a screw 22, a fixing plate 23, an electrical connection head 24 and a spring 26. The fixing plate 23 is fixedly installed at the front end of the screw 22. The electrical connection head 24 is penetrated in the sleeve 21. The rear end of the screw 22 passes through the assembly hole 101 and is threadedly connected with the sleeve 21. The electrical connection head 24 abuts against the rear end of the screw 22. The terminal is installed on the copper busbar 1 by the cooperation between the screw 22 and the sleeve 21.

[0023] A thumb suction cup 25 is fixedly installed at the front end of the fixing plate 23, and a thumb groove is provided in the middle of the front end of the thumb suction cup 25. A plurality of anti-skid tooth patterns are provided inside the thumb groove to play an anti-skid role. When in use, the finger is placed in the thumb groove, and the thumb suction cup 25 is pressed to drive the fixing plate 23 to squeeze the copper bar 1, thereby limiting the movement of the fixing plate 23 and preventing the screw 22 from rotating when the sleeve 21 is rotated.

[0024] The power connection head 24 includes a power connection plate 243, a rotating tube 244 and a wire 245. A sleeve 241 is fixedly installed at the rear end of the power connection plate 243. A butt tube 242 is fixedly installed at the rear end of the sleeve 241. The butt tube 242 is elastic. A plurality of shrinkage grooves are provided at the rear portion of the outer wall of the butt tube 242. The power connection end of the wire 245 passes through the butt tube 242 and is arranged in the sleeve 241 and butts against the power connection plate 243. The front portion of the rotating tube 244 is a threaded through hole with a constant inner diameter, and the rear portion of the rotating tube 244 is an extrusion through hole with a gradually reduced inner diameter. The front portion of the rotating tube 244 is threadedly connected with the sleeve 241, and the rear portion of the rotating tube 244 is sleeved on the outside of the butt tube 242. The rotating tube 244 is rotated to drive the rotating tube 244 to move forward. The extrusion through hole squeezes the butt tube 242, causing the rear portion of the butt tube 242 to shrink inward, thereby clamping the wire 245.

[0025] A through hole 211 for the wire 245 to pass through is formed in the middle of the rear end of the sleeve 21 .

[0026] The spring 26 is sleeved on the outside of the rotating tube 244 and is arranged between the power connection plate 243 and the rear wall of the sleeve 21. When the sleeve 21 is rotated, the power connection head 24 is driven to approach the screw 22. The spring 26 presses the power connection plate 243, so that the power connection plate 243 abuts against the screw 22, thereby achieving conduction.

[0027] A baffle 212 is fixedly installed on the front of the outer surface of the sleeve 21 . The baffle 212 and the fixing plate 23 clamp the copper bar 1 . The copper bar 1 conducts electricity to the sleeve 21 and the fixing plate 23 , and then transmits it to the electrical connector 24 through the screw 22 .

[0028] The outer surface of the sleeve 21 is provided with anti-skid teeth to facilitate the power personnel to rotate the sleeve 21.

[0029] The sleeve 21 , the screw 22 and the fixing plate 23 are all made of conductive metal, and the electricity of the copper bus 1 is conducted to the electrical connector 24 through the sleeve 21 , the screw 22 and the fixing plate 23 .

[0030] The working principle of the utility model is as follows: when in use, the screw 22 is inserted from the front of the assembly hole 101, and then the sleeve 21 is rotated to be threadedly connected with the screw 22, so as to clamp the copper bar 1. When the sleeve 21 is rotated, the fingers of the other hand tightly press the thumb suction cup 25 to prevent the screw 22 from rotating when the sleeve 21 is rotated, so that the sleeve 21 and the screw 22 are connected more firmly.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
