The invention discloses a wiring harness terminal which comprises a terminal body. The wiring harness terminal is characterized in that the terminal body is composed of a terminal self-locking area, a wire core pressing connection area, a buffer transition area and an insulation pressing connection area, wherein the terminal self-locking area, the wire core pressing connection area, the buffer transition area and the insulation pressing connection area are sequentially arranged, a self-locking opening is formed in the back end of the terminal self-locking area, an opening is formed between the terminal self-locking area and the wire core pressing connection area, a wire core in the wire core pressing connection area can be conveniently extended out from the opening, the two sides of the end face of the wire core pressing connection area are respectively provided with a front protection opening and a back protection opening, the wire core pressing connection area is connected with the insulation pressing connection area through the buffer transition area, and a material belt cutting point is arranged at the back end of the insulation pressing connection area. According to the wiring harness terminal, the problems that a wiring harness terminal in the prior art cannot be locked in a protective sleeve, inconvenience is brought to follow-up machining, a wire core of a wiring harness is easily damaged, and a protruding opening is reserved due to deformation after pressing connection are solved, the wiring harness terminal is simple in structure, convenient to use and capable of guaranteeing better pressing connection between the wiring harness and the terminal, and the good quality is achieved.
