Abstract

PURPOSE:To aim at providing a completely united composite conductor by inserting the head section of a molding material which is bi-split into first and second channels, into a space in both side engaging edge sections of a crown-like band member. CONSTITUTION:A crown-like band member SUS made of a wear-resistant metal plate is curved into a C-like cross-sectional shape so as to have arcuated engaging edge sections 1, 1. A highly conductive metal molding material Al is composed of first and second channel sections 4, 5 which are united together so as to form an engaging head section 6 in the lower section thereof. A half piece head part 9 of the channel section 4 has an outward facing part which is a bell-like shape bulged locking shoulder part 10, and the opposite side surface has a concave side surface which is bent so as to provide a guide surface 13. Further, a half-piece head part 15 has a shape which conforms along with the guide surface 13. The head part 9 of the first channel section 4 is inserted into an engaging space in the band member SUS, and thereafter the channel section 5 is inserted along the guide surface 13 so that the channel sections 4, 5 are united together in the locking condition by the engaging edge sections 4, 5, and are fastened together by bolts.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for use in sliding current collectors by synthesizing a highly conductive metal shape material such as aluminum and a wear-resistant metal strip material such as stainless steel. This invention relates to improvements in composite conductors constructed as described above.

[Conventional technology and its problems]

Conventionally, conductors for sliding current collectors composed of a highly conductive metal shape material such as aluminum and a wear-resistant metal strip material such as stainless steel have been described, for example, in Japanese Patent Publication No. 57-33177. As shown in the figure, bend the wear-resistant metal strip into a roughly U-shape, fit it into the six high-conductivity metal shapes, and swage it so that the caulking ribs on the shapes hold both edges of the strip. For example, as described in Japanese Utility Model Publication No. 59-19627, a wear-resistant metal strip is curved into a substantially C-shape to form a channel, and then a highly conductive shaped material is formed. It has been proposed that a grooved protrusion is inserted and a pattern is cut into the groove (thereby expanding the protrusion to integrate pressure welding to the wear-resistant metal strip). However, it cannot be said that satisfactory results have been obtained with any of these methods.

In other words, in the case of the former caulking rib, the wear-resistant metal strip that is covered in a substantially U-shape is hard, as typified by stainless steel, so when pressed inward by the caulking rib, As a result, an elastic repulsion force is generated corresponding to the amount of pressure applied to the ribs, and this repulsion force pushes the caulking ribs outward and causes them to peel off.As a result, the wear-resistant metal strip material becomes a highly conductive metal shape material. Karanuki could have fallen.

In addition, in the case of the latter case, it is necessary to
It is necessary to widen and deform a wear-resistant metal strip with a narrow frontage like a letter shape by driving a wedge into a convex part of a highly conductive metal profile that is press-fitted from the width of the width into an internal space wider than that width. However, the deformation resistance of the convex part is quite large, and if the convex part is not easily deformed, the pressing force to the wear-resistant metal strip tends to be insufficient, and it is difficult to obtain a firm electrically conductive contact. There was a drawback that the bonding was difficult.

In any of these cases, plastic deformation of the highly electrically sensitive metal profile is required in order to achieve bonding to the wear-resistant metal strip, and special tools are required to achieve the composite integration. ? 3 [The reality is that a crude method is used, and it has not been possible to provide a highly reliable yet economical composite conductor.

In view of these problems of the prior art, it is an object of the present invention to provide a composite conductor of this type that can be easily and reliably integrated into a composite conductor.

[Means for solving problems]

In order to achieve the above object, the composite conductor of the present invention has a cross section of approximately C
By combining a crown-like band material which is curved into a letter shape and has locking edges on both sides, and a section having a head that fits into the internal space between the both locking edges of this crown-shaped band material. The shape member is divided into a first channel part and a second channel part so as to partially define the head part,
These first and second channel portions have locking shoulders on opposite sides of the head that are engageable with the locking edges of the crown band, the locking shoulders being engageable with the locking edges of the crown band. They are assembled and bolted together with the head fitting properly in such a way that it engages with both locking edges.

〔Example〕

Figure 1 shows a cross section of the completed composite conductor, and Figure 2 shows the state of the composite conductor before it is synthesized.
is a shape material made of an extruded material of a highly conductive metal material such as aluminum, and SUS is a crown material made of a wear-resistant metal plate such as stainless steel.

Therefore, the crown band SUS is curved to have a substantially C-shaped cross section, and arch-shaped locking edges 1° are formed on both side edges, and these locking edges 1, 1 In between, a limited opening 2 and an enlarged internal space 3 are set inside the opening 2, and this internal space 3 is formed by a shape material M to be described later.
This will be the incorporation-appropriation department.

One of the mold members M is made up of a first channel part 4 and a second channel part 5 which are in a relationship of joining together, and an engaging head 6 is formed at the lower part of the joining.

The first channel part 4 has a flange 7 formed in an upper part thereof so as to protrude so that the supporting insulator can easily engage with the first channel part 4.
A columnar part 8 hanging from the center of the lower surface of this flange 7
A half-piece head 9 is formed at the lower end of the columnar portion 7. The half-piece head 9 has a locking shoulder 10 that bulges out like a bell in the outward facing part, and a flat and concave side surface 1) on the opposite side.
A guide surface 13 is provided which extends from the tip toward the lower surface 12 in a sliding manner.

On the other hand, the second channel part 5 mainly includes a half-piece columnar part 14 and a half-piece columnar head 15 is formed at the lower end thereof.

The half-piece head 15 has a locking shoulder 16 that bulges out like a bell in its outwardly facing part, and fits into the recessed side 1) of the first channel part 4 on the opposite side. It has a flat side surface 17, and an intersecting corner 19 between the linear surface 17 and the end surface, that is, the lower surface 18, is finished in an arc shape.

Now, if each part is shaped in this way, first, as shown in FIG. It is taken into the internal space 3 through the restricted opening 2, and the front end surface 12 of the band SUS is inserted into the inner space 3 through the restricted opening 2, and the locking shoulder 10 is fitted inside the locking edge 1 on one side of the band SO3. Place it on the inside to prepare for later work.

Next, the second channel part 5 is positioned in the limited opening 2 of the crown band SUS in order to introduce the half-piece head part 15 into the internal space 3 of the crown band SUS, and the intersecting corner part ]9 is the first channel part. The flat side surface 14 is rotated as shown by the arrow toward the concave side surface 1) of the part 4 so as to come into contact with the concave side surface 14.

Through this series of operations, the second channel part 5 slides from the concave side surface 1) of the first channel part 4 to the guide surface 13 of the turning part, and in the final stage, the intersecting corner part 19 slides onto the locking shoulder. The portion 16 is in a position to fit inside the locking edge 1 on one side of the crown band SUS, and the distal end surface 18 is seated on the inner surface of the crown band SUS, thereby connecting to the first channel portion 4 of the second channel portion 5. The merging is done.

In this combined state, the half-piece head 9 of the first channel part 4 and the second half-piece head 15 of the channel part 5 form an enlarged head 6.

This enlarged head 6 is arranged such that the opposing side surfaces 7 and 1) come into pressure contact with each other in a position in which the locking shoulders 10.16 engage with both locking edges 1.1 of the SUS crown band material. , both locking shoulders 10.
16 width between the locking edges 1. By forming the head 6 to be slightly larger than the inner width of the SUS crown, in such a combined state, the head 6 fits into the internal space of the SUS crown band, and internal pressure is applied to the inner surface of the SUS band, resulting in a predetermined contact pressure. The shape material M combined with the crown member SuS is fitted and integrated.

The combined first channel part 4 and second channel part 5 are fastened by passing a port 20 through the columnar part 8 and half-piece columnar part 14 and tightening with a nut 21. It completes the work.

Incidentally, a conductive compound may be applied to the joint surface between the first channel 4 and the second channel 5 and the joint surface between the head 6 and the crown band SUS to help electrical continuity.

〔Effect of the invention〕

As described above, in the composite conductor according to the present invention, the fitting engagement of the profile material to the crown band material is performed at the same time as the assembly and combination of the first channel part and the second channel part of the profile material. Unlike conventional composite conductors, which are secured to the strip by plastic deformation, special tools and complicated methods are not required, and complete joining and integration can be achieved with extremely simple operations. , therefore,
This type of composite conductor will have a tremendous impact on industry as it will be made more reliable and more economical.
