Abstract

PURPOSE:To join both an aluminum solid material and an electric conductor into an integrated body by forming a longitudinal groove on the side surface, on which a current collector is abutted, of a long solid aluminum material and putting into this longitudinal groove the base part of a long stainless steel electric conductor, which is provided with a pull-off checking part, together with applying the compressive plastic work to the aluminum material from its both sides. CONSTITUTION:Trapezoid grooves 2 are formed in the longitudinal direction at the bottom surface of long solid aluminum material having a sectional form of a letter I. Long, stainless-steel, electric conductors 3 each having a trapezoid sectional form 3, and provided with pull-off checking part 4 at its both inclined side surfaces, are put into this groove 2. The solid aluminum material in to which the stainless-steel conductor 3 is put is compressed from its both sides as the plastic work, thereby completely sealing the entire the contact surface between both 1 and 3. Further, a part of the inner wall surface of the longitudinal groove of the solid aluminum material is put into the pull-off checking part 4 under pressure thereby joining both 1 and 3 into an integrated body to fabricate a solid trolley wire. With this contrivancae, both 1 and 3 are thoroughly joined for their entire length, and thus electric corrosion caused by rain- water can surely the prevented.

２が部分的に脱落する危険性がある等の欠点があった。(Prior Art) As shown in FIG. 3, a conventional rigid trolley wire of this type has two parallel longitudinal grooves 11, 11 formed on the collector contact side surface of a long aluminum rigid body 10 having a cross-sectional shape. A long stainless steel conductor 12 with a concave cross section is fitted into the groove 11.11, and the fitted portion is compressed from both sides of the aluminum rigid body 10 by rolling rollers, presses, etc. over the entire length to separate the aluminum rigid body 10 and the stainless steel conductor. 12 were integrally pressure-welded. In such a conventional rigid trolley wire, it is extremely difficult to pressure-weld the long aluminum rigid body 1o and the long stainless steel conductor 12 with a gate-shaped cross section so that a small gap does not occur at the joint interface. Through the small gap remaining at the bonding interface between the aluminum rigid body 10 and the stainless steel conductor 12, rainwater, etc. enters and accumulates in the concave groove of the stainless steel conductor 12, which is bent to have a concave cross section, due to capillary phenomenon, and the aluminum solid body 10 and the stainless steel conductor 10 are bonded together. Conductor 1
Electrolytic corrosion occurs between the dissimilar metals of the rigid trolley wire and the electrical properties and mechanical strength of the rigid trolley wire are significantly reduced.
There were drawbacks such as the risk that part 2 would fall off.

After fitting the base of a long stainless steel conductor with a pull-out stopper, the aluminum rigid body fitted with the base of the stainless steel conductor is compressed and plasticized from both sides to ensure that the mating interface is tightly closed. At the same time, a part of the aluminum rigid body is press-fitted into a pull-out stop formed at the base of the stainless steel conductor, and the aluminum rigid body and the stainless steel conductor are integrally pressure-welded.
