Aluminum wire connection terminal unit and coil device

Abstract

PROBLEM TO BE SOLVED: To facilitate wire arrangement for arranging an aluminum electric wire etc. and connecting the aluminum electric wire with an electric wire connection part, simplify the connection work between the aluminum electric wire and another electric wire, and reduce the work hours.SOLUTION: An aluminum electric wire connection terminal unit includes: an aluminum electric wire connection terminal including an aluminum core wire connection part in which an aluminum core wire end part of an aluminum electric wire is crimped, held, and is joined by soldering and thereby making a connection therebetween, and another electric wire connection part to which another electric wire is connected; and a terminal board. Guide parts for facilitating wire arrangement of the aluminum core wire end part are integrally formed at both of the aluminum electric wire connection terminal and the terminal board.

Description

technical field [0001] The present invention relates to an aluminum electric wire connection terminal installed at the end of an aluminum core wire of an aluminum electric wire and used for connection with other electric wires and a connection terminal unit including its terminal base, and particularly relates to a device for use in a coil composed of an aluminum electric wire The lead wires of the coils in the coil device are connected to the aluminum electric wires that are lead wires of other electric wires, etc., to the terminal unit. Background technique [0002] Reactors used for countermeasures against high-order harmonics of consumer electronic equipment are constructed such that a coil is wound on a bobbin, an iron core is mounted on the bobbin, and the lead wires of the coil are connected to the connection terminals assembled on the terminal board. On the other hand, lead wires etc. which are other electric wires are connected to this connection terminal. In such ...

Problems solved by technology

[0008] However, in the existing aluminum wire connection terminal unit, it is difficult to assemble the coil device and take out the aluminum wire and the end of the aluminum core wire to connect to the wire connection part, and the assembly work is also cumbersome. The above-mentioned riveting sheet for aluminum wire holding is also unstable in the wiring process, resulting in variation in the holding state, which also causes unevenness in soldering accuracy.

Therefore, in order to correct it, it is necessary to perform multiple times of soldering, etc., resulting in an increase in man-hours. In addition, for example, special tools are required for coating work to prevent electrolytic corrosion, which inevitably leads to complicated work.

[0009] In addition, if the exhaust of the flux gas generated by the evaporation of the above-mentioned flux is insufficient during soldering, tiny pores may be included inside after soldering, which may cause electrical reliability problems.
