  • Patent number: 9954305
    Abstract: An electric connector, comprising: a housing, an insulation body received in the housing, and a plurality of terminals held in a plurality of slots of the insulation body. The insulation body comprises a first half body and a second half body separate from the first half body The first half body and the second half body are configured to be detachably assembled together. Therefore, when connecting cables in field, the insulation body may be separated into the first half body and the second half body first. Then the cables may be connected to the terminals held in the first half body and the second half body. The first half body and the second half body may be assembled together after the cables are connected. Using such a detachable insulation body provides larger operation space, thus easing connecting the cables to the terminals in the field.
