Problems solved by technology
Another reason for the above problems is that if copper electrical connection terminals are used to connect aluminum or aluminum alloy cable conductors, the copper will be in direct contact with the aluminum or aluminum alloy, so that copper and aluminum will undergo electrochemical reactions in the air, making the copper electrical terminals The connection terminal and the aluminum or aluminum alloy cable conductor are corroded, thus making the electrical connection between the aluminum or aluminum alloy cable conductor and the copper electrical connection terminal unreliable, and its environmental adaptability and durability are poor

Embodiment Construction
[0015] The present invention provides an electrical connection terminal, comprising: a metal connection part and another metal connection part, and one end of the one metal connection part is joined with one end of the other metal connection part so that One metal connection part is electrically connected to another metal connection part, and a seal is provided at the joint to isolate the joint from the outside world. The other end of one metal connection part is connected to another metal connection part. The other ends are used for electrical connection with the outer conductors of the same metal as the respective metals. It should be noted that a metal connection part refers to a connection part made of one metal, and another metal connection part refers to a connection part made of another metal. In addition, it should be noted that a metal mentioned in the present invention does not mean that only one metal element is contained, but that it may contain one metal element a...

The invention provides an electric connection terminal, which is used for building electric connection between two conductors which are made of different metals to ensure that the electric connection is reliable and enhance the environmental suitability and the durability of the electric connection terminal. The electric connection terminal comprises an interconnecting piece made of one metal andan interconnecting piece made of another metal, wherein one end of the interconnecting piece made of one metal is jointed with one end of the interconnecting piece made of another metal so as to realize the electric connection between the interconnecting piece made of one metal and the interconnecting piece made of another metal, a seal is arranged at the joint to ensure that the joint is isolated from the outside world, and the other end of the interconnecting piece made of one metal and the other end of the interconnecting piece made of another metal are respectively used for the electric connection with external conductors, the metals of which are the same.
Description
technical field [0001] The invention relates to an electrical connection terminal, in particular to an electrical connection terminal for establishing electrical connection between conductors respectively made of two different metals. Background technique [0002] In electrical engineering, when connecting two conductors, it is usually done using electrical connection terminals. For example, it is stipulated in the Construction Atlas of Construction Installation Engineering (Third Edition) that when connecting the cable conductor to the miniature circuit breaker, if the cross-sectional area of the cable conductor exceeds 2.5 square millimeters, it is necessary to use an electrical connection terminal to connect the cable conductor to the miniature circuit breaker. The conductor insertion end of a circuit breaker. [0003] Further, in electrical engineering, it is often necessary to use electrical connection terminals to connect conductors respectively made of two differen...
