- the conventional crimp terminal 1 for an aluminum electric wire when connecting a thick (large diameter) aluminum electric wire 5 in which the number of aluminum wires 6a is increased, the aluminum located at the center (center) of the core wire 6 is used. Since it is difficult to destroy even the oxide film on the surface of the element wire 6a, current flows only through the aluminum element wire 6a located outside the core wire 6, and concentrated resistance is easily generated. Due to this resistance, problems such as a temperature rise of the core wire 6 and poor conduction occurred.
- the present invention has been made to solve the above-described problems, and an object of the present invention is to reliably destroy the oxide film on the surface of the core wire located in the center to obtain a good electrical connection.
- the object is to provide a crimp terminal for an aluminum electric wire.
- a first aspect of the present invention is a crimp terminal for an aluminum electric wire, comprising the following: a crimp part connected by crimping to a core wire of the aluminum electric wire; and the crimp part Serrations formed on the inner surface of the adhesive; in the above configuration, serrations are further formed on the outer surface of the crimping portion.
- the first aspect of the present invention by further forming serrations on the outer surface of the crimping part, it is possible to reliably destroy the oxide film on the surface of the core wire located in the center part and obtain a good electrical connection. it can.
- the crimp portion is formed in a substantially U shape by a base and a pair of crimp pieces formed on both sides of the base; A plurality of serrations are formed on the inner surface of the base and the inner surfaces of the pair of crimping pieces so as to extend in a direction perpendicular to the length direction of the core wire; and the outer surfaces of the pair of crimping pieces; A plurality of serrations extended in a direction perpendicular to the length direction of the core wire is formed at least on the tip side.
- the crimping portion is formed in a substantially U shape by the base and the pair of crimping pieces formed on both sides of the base, and the inner surface of the base and each inner surface of the pair of crimping pieces. Forming a plurality of serrations extending in a direction orthogonal to the length direction of the core wire, and a plurality of serrations extending in a direction orthogonal to the length direction of the core wire at least on the distal end side of each outer surface of the pair of crimping pieces.
- the oxide film on the surface of the core wire located outside is destroyed by the unevenness of the plurality of serrations formed on the inner surface of the base of the crimping portion and the inner surfaces of the pair of crimping pieces, and the pair of crimping pieces A good electrical connection can be obtained by destroying the oxide film on the surface of the core wire located at the center by the unevenness of the plurality of serrations formed on the outer surfaces of each.
- FIG. 1 is a perspective view showing a state before crimping an aluminum wire of a conventional crimp terminal for an aluminum wire.
- FIG. 2 is a cross-sectional view showing a state in which the aluminum wire of the conventional crimp terminal for aluminum wire is crimped.
- FIG. 3 is a perspective view showing a state before crimping the aluminum electric wire of the aluminum electric wire crimp terminal according to the embodiment of the present invention.
- FIG. 4 is a cross-sectional view of a state in which the aluminum electric wire of the aluminum electric wire crimp terminal is crimped.
- FIG. 5 is a cross-sectional view taken along line VV in FIG.
- FIG. 6 is an enlarged cross-sectional view of a VI portion in FIG. It is.
- a crimp terminal 10 for an aluminum wire is integrally formed with a copper fastening portion 11 having a through-hole 11a through which fastening means such as a bolt (not shown) can pass, and the fastening portion 11. It has a crimping part 12 which is crimped and connected to a core wire 21 formed by twisting a plurality of 20 aluminum strands 21a.
- the crimping portion 12 is formed in a substantially U shape by a base 13 and a pair of crimping pieces 14, 14 integrally formed on the left and right sides of the base 13.
- the inner surface 13 a of the base 13 and the inner surfaces 14 a of the pair of crimping pieces 14, 14 have a plurality of long lengths extending in a direction orthogonal to the length direction of the core wire 21.
- Serrations 15 are formed continuously.
- a plurality of short serrations 16 extending in a direction orthogonal to the length direction of the core wire 21 are formed on the distal end 14 c side of each outer surface 14 b of the pair of crimping pieces 14, 14.
- the aluminum electric wire 20 includes a core wire 21 in which a plurality of aluminum wires 21 a made of aluminum or an aluminum alloy are twisted, and an insulating coating 22 that covers the core wire 21. Yes.
- the pair of crimping pieces 14, 14 of the crimping portion 12 of the aluminum wire crimping terminal 10 is replaced with the pair of crimping pieces 14.
- the inner surface 13a of the base 13 of the crimp portion 12 and each of the pair of crimp pieces 14 and 14 are connected.
- the oxide film on the surface of the aluminum wire 21a located outside the core wire 21 is broken by the unevenness formed by the grooves of the plurality of long serrations 15 formed continuously on the inner surface 14a and the inner surfaces 13a, 14a.
