Plug-in apparatus for a vehicle

A plug-in apparatus, comprising a wire inlet connection portion and a wire outlet connection portion, wherein:

• a fuse is connected between a first end of the wire inlet connection portion and a first end of the wire outlet connection portion, a second end of the wire inlet connection portion is connected to a power supply wire, and a second end of the wire outlet connection portion is connected to a load wire;
• the second end of the wire outlet connection portion has at least one connection branch which serves as a load interface;
• the plug-in apparatus further comprises at least one connection terminal, to which the second end of the wire inlet connection portion and/or the at least one connection branch is connected, and the connection terminal is connected to the power supply wire or the load wire;
• the plug-in apparatus further comprises a positioning plate, on which the at least one connection terminal is disposed to penetrate therethrough;
• the plug-in apparatus further comprises a plug-in portion provided with at least one plug-in through-hole penetrating from a first end to a second end thereof;
• one end of the connection terminal is connected to the second end of the wire inlet connection portion or the connection branch, the other end of the connection terminal extends into the plug-in through-hole from one end of the plug-in through-hole, and the other end of the plug-in through-hole is connected to the power supply wire or the load wire, wherein the plurality of connection terminals are plugged into the plurality of plug-in through-holes in a one-to-one correspondence, the load wire or the power supply wire extends into the plug-in through-hole, and the connection terminal crimps the load wire or the power supply wire in the plug-in through-hole to realize the connection between the connection terminal and the load wire or the power supply wire;
• and
• the plug-in apparatus further comprises a housing, in which the positioning plate, the wire inlet connection portion and the wire outlet connection portion are disposed, and the plug-in portion is detachably connected to the housing from one side of the housing, and a first end of the plug-in portion is located in the housing.
