    Cross reference to the related request
    This application claims the benefits of Chinese Patent Application No. CN201620513929.9 filed on May 31, 2016 at the State Intellectual Property Office of China, the full description of which is incorporated herein by reference.
    Field of the Invention
    The embodiments of the present description generally relate to an electrical connector, particularly an electrical connector for electrically connecting two cables.
    Description of the related technique
    During the assembly of an electrical equipment, for example, appliances, it is often required to connect two wires to each other. In the prior art, the worker normally removes the insulating layer of the two wires to be connected to the pliers, and then twists the 15 exposed conductors of the two wires together, and finally wraps with the insulating tape on the connection of the two wires . Said method for manually connecting two cables is very inefficient, the operation is more complex, and the connection is not reliable, often causing poor contact of the conductors of the two cables.
    In addition, an electrical connector according to the prior art includes an upper housing and a lower housing. The lower housing is formed with a cavity adapted to be inserted with at least two cables, and the upper housing is provided with a piercing terminal. When the upper housing is assembled to the lower housing, the drilling terminal punches and inserts into the insulating layers of the two cables, and comes into electrical contact with the conductors of the two cables, thereby electrically connecting the two cables each. This solution partially solves the problems of complex operation and unreliable connection. However, the upper case and the
    Bottom housing are two separate components, which need to be assembled separately, so that there is still a problem of low assembly efficiency.
