AI Technical Summary
Technical Problem
Connectors made of different metals are prone to galvanic corrosion when water adheres to the contact point between terminals.
Method used
A connector design featuring a relay terminal with an intermediate ionization tendency between the first and second terminals, equipped with a press-fit fixing portion that scrapes off the oxide coating on the mounting hole, reducing contact resistance and simplifying the mounting process.
Benefits of technology
Suppresses galvanic corrosion and simplifies the mounting process by using a relay terminal with a press-fit fixing portion that removes oxide film, ensuring reliable electrical connection.

Abstract
To provide a connector which can suppress galvanic corrosion between terminals.SOLUTION: A connector comprises: a first tabular terminal 21 having a fitting hole 27; a second terminal 51; a relay terminal 30 provided between the first terminal 21 and the second terminal 51; and a bolt member 40 which fastens and fixes the first terminal 21, second terminal 51, and the relay terminal 30 to one another. The first terminal 21 and the second terminal 51 are made of different types of metal. The relay terminal 30 is made of metal whose ionization tendency is in the middle of those of the first terminal 21 and the second terminal 51. The first terminal 21 has an oxide film on the surface, of the first terminal 21, including an inner circumferential surface of the fitting hole 27. The relay terminal 30 has a press-in fixing part 32 which is pressed in and fixed to the fitting hole 27. The press-in fixing part 32 has: an insertion part 34 which is inserted into the fitting hole 27; and a protruding part 35 which protrudes from an outer circumferential surface of the insertion part 34 so as to scrape the oxide film on the inner circumferential surface of the fitting hole 27.SELECTED DRAWING: Figure 2
