JPS5838721Y2 - Conductive structure of rubber slider for current collection - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to an improvement in the conductive structure of a rubber slider for current collection.

The present applicant previously filed Japanese Patent Application No. 52-37056 (Japanese Unexamined Patent Publication No. 52-37056)
No. 3-124814) etc., the current collecting part is made up of a plurality of current collecting elements supported by rubber springs, and the current collecting part is independent of the current collecting part. A load supporting section, which is made of a sliding plate made of a highly abrasion resistant and slippery material such as, supported by a rubber spring having a spring constant larger than that of the rubber spring of the current collecting section, is mounted on the same substrate. We proposed a rubber slider for current collection.

The above-mentioned rubber slider for current collection is such that when the device is pressed against the power supply line, most of the load is borne by the load supporting part, so that the current collection part keeps the current collecting element in constant contact with the power supply line and collects the current from the power supply line. Since it is sufficient to have an extremely low spring constant sufficient to carry electricity, the wear and sliding noise caused by the contact sliding of the current collecting element with the power supply line are significantly reduced, and
It is capable of efficiently collecting current by following the power supply line well and maintaining constant contact with it. However, since the current collecting element is supported on the substrate by an electrically insulating rubber spring, the current collecting element is able to collect current efficiently. The applied current also needs to be efficiently transferred to the substrate (and from the substrate to the vehicle drive).

In the above-mentioned invention and others, in order to improve the efficiency of conduction from the current collecting elements, the current collecting elements are connected to each other by a common wire, and each current collecting element is connected to the substrate by a lead wire.

The common wire and the lead wire were also made of flexible metal braided wire so as not to hinder the reduction in the spring constant of the current collecting section.

As the number of components of the common wire and lead wire increases, the probability that electrical conduction efficiency will decrease due to the occurrence of poor electrical connections, partially burnt out parts, etc. increases accordingly.

The present invention solves the drawbacks of cutting, has a large current capacity, efficiently conducts electricity from the current collecting element to the substrate, and has a lead wire for a rubber slider for current collection that does not hinder the reduction of the spring constant of the current collecting part. It proposes a structure.

Hereinafter, the present invention will be explained with reference to an illustrated example. In FIG. The sliding plate 5, which is independent of the current collecting part 1 and made of the above-mentioned highly abrasive and slippery material, is equipped with a rubber spring 6 having a spring constant larger than that of the rubber spring 4 of the current collecting part 1. The load support section 2 is supported by a substrate 7 made of a conductive metal.
It is configured by being attached to the top.

In the current collecting rubber slider, the plurality of current collecting elements 3 are electrically connected to the substrate 7 made of conductive metal by the conductive material 8. As shown in FIGS. 2 and 3, one edge of the metal knitted fabric 8 is used as the material 8, and one edge of the metal knitted fabric 8 is connected to a plurality of the current collecting elements 3... are commonly connected to their lower surfaces by a pole 1-9, preferably extending downwardly along the inner surface of the rubber spring 4, and connect the other end edge of the metal knitted fabric 8 to the rubber spring 4. A mounting plate 10 made of a conductive metal vulcanized and bonded to the lower end of the board 7 is interposed therebetween, and the board 7 is connected to the board 7 by bolts 11.

In addition, in the figure, 12 is a vibration damping rubber plate attached to the lower surface of the current collecting element.

As explained in detail above, the present invention includes a current collecting section formed by supporting a plurality of current collecting elements with rubber springs, and an independent current collecting section,
and a load supporting section in which a sliding plate made of a highly abrasion resistant and slippery material is supported by a rubber spring having a spring constant larger than that of the rubber spring of the current collecting section, are mounted on the same substrate. In this way, the current efficiently collected by the current collecting element can be transferred to a single sheet which is commonly connected to each current collecting element at one end thereof and whose other end is connected to the substrate. The high current capacity conductive material made of metal knitted fabric material can efficiently transmit electricity to the substrate made of conductive metal.
The conductive material does not at all hinder the reduction of the spring constant of the current collector.
