本発明は、剛性を持った導電部本体に、集電体接触部材
を結合一体化して構成する複合剛体トロリーに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composite rigid trolley configured by integrally bonding a current collector contact member to a rigid conductive body.
この種剛体トロリーは、導電部本体がその構成素子の剛

体から電流を伝達せ［７めて接触する集電体への電流の
授受を行なわしめるようにしたものである。This type of rigid trolley is constructed such that the conductive body serves as a main body that overcomes the rigidity of its constituent elements and also serves as a matrix that transmits current, and the current collector contact member transmits current from the conductive body. [7] Current is transferred to and from the current collector that comes into contact with it for the first time.
従って導電部本体と集電体接触部材との電気的接続を充
分に行ない、そして電流を伝達させるときの電気的抵抗
を増加させないことが望ましい。Therefore, it is desirable to have a sufficient electrical connection between the conductive part main body and the current collector contact member, and to avoid increasing the electrical resistance when transmitting current.

業は非常にＪｔｂ介なものとなっている。FIG. 1 shows a conventional rigid trolley, which consists of a conductive body 1 such as a T-shaped aluminum pedestal, and a current collector contact member 2 such as a copper trolley.
It is integrated into the conductive part main body 1 by being clamped by claws 5a, 5a of aluminum ears 5, 5 attached with a bolt 3 and a nut 4. In this case, the current transmission method from the conductive part body 1 to the current collector contact member 2 is as follows:
This is done via an aluminum ear 5 that is in sandwich contact with both the main body 1 and the member 20, but since both the ear 5 and the main body 1 are made of aluminum, the oxide film (alumina) generated on the surface is sufficiently removed. It is necessary to make electrical contact after polishing and removing the wires, and since a large number of ear wires are attached at predetermined intervals in the longitudinal direction of the main body 1, the work is very tedious.
また上記とは別の手段として、リード線材の銅製イーヤ
を用いて本体１に取付け、そして銅製トロリー２に挾持
させ、リード線をアルミニウム製架台１に接続するもの
がある。In addition, as another method, there is a method in which the lead wire is attached to the main body 1 using a copper ear, which is then held by a copper trolley 2, and the lead wire is connected to the aluminum frame 1.
このものによれば、研曜作業を大幅に軽減できるのであ
るが、リード線材の銅製イーヤはアルミニウム製イーヤ
に対し特別に作られる為、部品数を多くする欠点があっ
た。According to this method, the grinding work can be greatly reduced, but since the copper ears of the lead wire material are made specially for the aluminum ears, it has the disadvantage of increasing the number of parts.

困難なことであった。In any of the above methods, the bolts and nuts may not be tightened properly, and the contact between the ear and the main body and the current collector contact member may be incomplete, or the bolt may be loosened, making it uneconomical. It was extremely difficult to maintain a stable connection.
また接触部分で生じやすい腐食等でもその電気的接続状
態は変化するので信頼性に乏しい欠点があった。In addition, the electrical connection state changes due to corrosion that is likely to occur at the contact portion, resulting in poor reliability.
本発明は、前記した従来技術の欠点を解消する為に、導

を提供するものである。In order to eliminate the drawbacks of the prior art described above, the present invention provides a conductive part main body and a current collector contact member fixed longitudinally in the longitudinal direction of the current collector contact member. The present invention provides a method for configuring a rigid trolley in which the electrical connection to the main body can be carried out extremely efficiently without using special parts, and the electrical performance can be achieved with stable electrical performance.
すなわち、本発明の要点は、導電部本体同士で設定され

部本体と集電体接触部材との電気的導通部を形成するこ
とにある。That is, the gist of the present invention is that when connecting the abutting ends in the vertical direction of the conductive part bodies with the conductive connecting member, the conductive connecting member and the current collector contacting member are electrically conductive. The purpose is to weld and integrate the conductive part body with the part body, thereby forming an electrically conductive part between the conductive part body and the current collector contact member.
導電部本体はその構成素子上剛性がある為数メートルな

本体は電流を伝送する都合上、突き合せられた端部間を
導電性接続部材で接続する必要がある。Because the conductive part body is rigid due to its constituent elements, it is a standard length body of several meters to several tens of meters. Therefore, in an actual laying line, a plurality of conductive parts are connected end to end in the vertical direction to form a long element. configured. For the purpose of transmitting current, it is necessary to connect the abutted ends of the plurality of conductive body bodies with a conductive connecting member.
本発明は特にその導電部本体同士の接続部に着目し、当
該導電部本体同士の接続と併せて導電部本体と集電体接
触部材の電気的接続をも行なおうとするものである。The present invention particularly focuses on the connecting portion between the conductive part bodies, and attempts to connect the conductive part bodies with each other, as well as electrically connect the conductive part bodies with the current collector contact member.
以下実施例図面に基いて説明する。An explanation will be given below based on the drawings of the embodiment.

ミニウム製の押出形材によって得られたもので、横断面
Ｔ字形の縦長定尺体よりなる。FIG. 2 shows a main body of a composite rigid trolley constructed according to the present invention. In the figure, reference numeral 10 denotes a conductive part main body, which is obtained from an extruded aluminum member and is a vertically elongated regular body with a T-shaped cross section.

圧接成型用ロールを通して冶金学的に結合しあって作り
出されている。20 is a current collector contacting member and consists of a stainless steel strip 21 which receives direct contact with the current collector, and an aluminum portion 22 integrally joined to one side of the stainless steel strip 21, which is formed by a pair of pressure welding moldings. They are produced by metallurgically bonding each other through rolls.

てあシ、これはいわゆるくさび効果をねらって付加され
ているものである。The current collector contacting member 20 is constructed by fitting a protrusion 11 that extends continuously in the longitudinal direction in the central part of the conductive part main body 10 into a recess 22a continuously formed in the longitudinal direction in the aluminum portion 22. By caulking the portion 22 from both sides with pressure rolls, it is continuously fixed to the conductive portion main body 10 along the longitudinal direction. In particular, as a method of increasing the bonding strength between the two through fixation, acute triangular protrusions 12.12 are formed at both corners of the tip edge of the protrusion 11, and these protrusions 12.12 are made to bite into the interior of the aluminum portion 22. The reeds are added to create a so-called wedge effect.

る。In this way, the integrated conductive part main body 10 and current collector contact member 20 are compressed together, so some electrical continuity occurs, but they are not integrated simply by mechanical contact while being pressed together. Due to the fact that the oxide film that forms on the surface of the aluminum material is likely to be interposed between the press-contact surfaces, a very high electrical resistance exists between the two, and stable electrical conduction is not possible. It's not enough to make it work.
