Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings of the specification:
The utility model relates to a kind of electric fittings of new-energy automobile, are a kind of for new energy vapour specifically
The charging socket of the replaceable contact pair of vehicle comprising include charging socket ontology 1 and sleeve shell 2, the charging socket
Ontology 1 is provided with the first accommodating cavity, the second accommodating cavity is arranged in the sleeve shell, the first accommodating cavity and the second accommodating cavity are coaxial
It is arranged and the end of the two is in contact, so the first accommodating cavity is just connected to the second accommodating cavity becomes a complete accommodating
Space, in the accommodating space setting contact pair, specifically, it is described contact to include replaceable sleeve 3 and crimping sleeve 4,
The containing portion being recessed inwardly is arranged in the bottom end of replaceable sleeve 3, and outwardly projecting extending portion, peace is arranged in the top of crimping sleeve 4
When dress, extending portion can be protruded into containing portion and contact, and specifically, extending portion and containing portion are that topside area is less than bottom
