Abstract

PURPOSE:To provide a current collector in which suppression of abrasion powder and stability in sliding can be realized through a simple structure by taking advantage of a wire composed of conductive spring material. CONSTITUTION:Linear wires having circular cross-section composed of conductive spring material, e.g. one of beryllium copper (C1700P-HM, BeCuP10-HT) or phosphor bronze for spring (C5210P-EH) of a combination thereof, are arranged in parallel and rings 2, 3 are fitted at the opposite ends and welded integrally. Intermediate wire part is then arched to form a sliding part 4 under same conditions for all wires.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a current collector that can be used as a current collector for an insulated trolley wire.

[0002]

2. Description of the Related Art For current collectors that slide on insulated trolley wires,
Brushes of copper-based sintered alloys have been mainly used. According to the brush, it is necessary to use a holder for carrying the brush, a clevis for receiving the holder, and an arm mounted with a spring for pressing the brush against the trolley wire.

[0003]

According to the above-mentioned brush, a complicated auxiliary structure is required with a large number of components,
It was difficult to simplify the structure.

Further, the brush generates abrasion powder as it slides, which adheres to the sliding surface of the trolley wire and induces disconnection, which causes a transmission error when used in a signal transmission system. There was a problem.

On the other hand, when a wire is manufactured from a material which becomes a sliding contact and has a spring characteristic and is formed into a sliding element, the structure can be simplified and a current collector in which abrasion powder is not easily generated can be obtained. However, it was not possible to put it into practical use immediately because there was a concern about stable current collection because the sliding part became a point.

The present invention provides a current collector of this kind which can achieve the simplification of the structure, the suppression of abrasion powder and the stability of sliding by utilizing the advantages of the wire made of the last conductive spring material. Has a purpose.

[0007]

In the current collector provided by the present invention, wires made of a conductive spring material are arranged in parallel and integrated in at least one terminal, and a wire portion between the terminal and the other terminal. The sliding part is formed by.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a preferred embodiment of the current collector of the present invention, in which reference numeral 1 is a wire made of a conductive spring material and is made of beryllium copper (C1700P-HM, BeC).
uP10-HT) and spring phosphor bronze (C5210P-E)
It is formed in a linear shape with a circular cross section by one or more combinations of materials such as H).

However, the wire 1 is assembled as a whole by attaching the rings 2 and 3 at both ends in a state where a large number of wires are arranged in parallel and welding them. Then, the middle of the restraint portions at both ends is formed into an arc shape, and the sliding portion 4 under the same conditions for all the wires at the bow portion.
Is formed.

The current collector of this embodiment has a so-called cantilever type in which one end of the current collector is fixedly supported by a member to be pulled by a mobile device and the other end is a free end. Can be used. It is suitable for one-way sliding travel.

FIG. 2 shows another embodiment of the current collector according to the present invention, in which the ring 2 at one end of the wire 1 is fixed to the inner wall of the hollow restraining jig 5 with screws 6. ,
With the ring 3 at the other end pressed into contact with the inner wall of the restraint jig 5, the wire 1 is projected in an arc shape outside the restraint jig 5, and at that portion, a sliding portion 4 with respect to the conductor 7 is formed.
Is formed.

In the current collector of this embodiment, since both ends of the wire are constrained in the constraining jig, the followability with respect to the conductor during sliding traveling becomes more stable, and reciprocal sliding traveling is possible. Is.

Although any of the above-described embodiments is shown as a current collector for a trolley wire, the current collector is not limited to this and can be used as a current collector for a slip ring.

[0014]

With the current collector of the present invention as described above, the wire itself made of a conductive spring material is used for predetermined sliding travel with the function of an arm and a brush, so that the structure is simple. It can be made compact and can be made compact.

Further, since all of the plurality of wires can slide under the same condition, the sliding portions are in multi-point contact, so that smooth and stable current collection can be performed in combination with the spring characteristics of the wires.
