The length of the terminal body 1 is greater than the length of the wire pressing buckle 2, and the insulation layer 31 is arranged on the terminal body 1.

[0028] As shown in Figure 1 , Figure 2 , the terminal body 1 is substantially rectangular in shape, the length of the terminal body 1 is 9.5-10.5 mm, the thickness of the terminal body 1 is 0.75-0.85 mm, and the width of the terminal body 1 is 3.5-4.5 mm. A front end surface 20 is formed on the side of the wire pressing buckle 2 away from the insulation layer 31, a rear end wall 11 is formed on the side of the terminal body 1 away from the front end surface 20, and a front end wall 12 is formed on the side of the terminal body 1 away from the insulation layer 31. The distance between the front end surface 20 and the rear end wall 11 is 7-9 mm.

[0029] By arranging the insulation layer 31 on the terminal body 1, the stress structure of the connection between the electric wire 3 and the wire pressing buckle 2 is optimized, which can effectively avoid the situation that the connection between the wire pressing buckle 2 and the terminal body 1 is crushed and broken due to the lever effect when the insulation layer 31 is crushed, significantly improves the connection strength, meets the application requirements of high-reliability electrical connection, and makes the overall structure more reasonable and the connection more firm.
