DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a trolley current collector used for powering various moving loads.

〔背景技術〕[Background technology]

As shown in FIG. 15, the current collector of the trolley system has a current collecting arm 30 attached to a movable load (not shown) via a mounting base 31 so as to be movable up and down, and a current collector at the tip of the current collecting arm 30. A current collector 33 attached to a holding frame 32 is pressed against a conductor 36 of a trolley wire 35 (FIG. 16) by a spring 34. The trolley wire 35 is suspended from a construction material 38 by a hanger 37. 39 is a lead wire.

The conventional current collector 33 is made of a current collector material that has excellent wear resistance and arc resistance. However, this caused the following problems.

■ In use, the allowable wear portion of the collector 33 that comes into sliding contact with the trolley wire 35 is a part of the upper surface of the collector exchange line l shown in FIG. Constructing the current collector material, which is an expensive special material, is uneconomical and increases the cost.

スポット溶接やねし締めで接続することが困難である。
(2) Since the current collector material generally uses a carbon-based molded product or a sintered alloy, it is difficult to connect the current collector 33 and the lead wire 39 by spot welding or screw tightening.

That is, since carbon and sintered alloy are materials that cannot be spot welded, lead +41A39 cannot be directly spot welded. Furthermore, since carbon and sintered alloys are brittle materials, caulking or tapping with a tap lacks reliability.

For these reasons, the connection of the lead wire 39 to the current collector 33 is as shown in FIG. 17 at -1'G.
A method is used in which a pressure terminal 40 is connected to one end of the pressure wire, the pressure terminal 40 is applied to the side surface of the current collector 33, and the pressure terminal 40 is tightened and fixed with a screw 41 and a nut 42.

However, when the lead vA39 is attached with the crimp terminal 40 and the screw 41, the space in this part becomes large.
In multi-conductor insulated trolley wires, the dimensions between the conductors are restricted.

(2) If the entire current collector 33 is made of carbon sintered alloy, the current collector 33 will be heavy. Therefore, the line separation characteristics during current collection running are poor. That is, when the collector 33 resists the spring 34 and separates from the wire due to frictional vibrations during running or a stepped portion of the trolley wire connection, the inertial force of the collector 33 is large.
The distance from the track increases.

According to this configuration, expensive materials with excellent wear resistance and arc resistance are required only for the sliding contact body, and expensive materials do not need to be used for supporting parts that do not require these properties. Economical. Metallic hemispheres are inexpensive because they can be easily pressed using sheet metal or the like. Furthermore, since the metal base and the sliding contact body are integrally molded, they can be easily fixed to each other.

As shown in FIG. 1, this current collector 1 has one embedded piece 2a embedded in metal, a sliding contact body 3 is integrally molded, and leads are attached to a lead wire attachment part 4 of a metal base 2. The wires 5 are spot welded, and then the remaining portion of the metal base 5 is covered with an insulator 6 such as synthetic resin by integral molding to form a block.

FIG. 13 and FIG. 14 show a current collector using this current collector. In the figure, reference numeral 10 denotes a mounting base, which is fixed to a moving load with a presser plate 11 and screws. Two current collector arms 12 are attached to the mounting base lO, and the current collector 1 is attached to the tips of the two current collector arms 12.

This configuration is economical because only the sliding contact body 3 needs to be made of an expensive material with excellent wear resistance and arc resistance. Since the metal base 2 and the sliding contact body 3 are integrally molded, they can be easily fixed to each other. Moreover, since a portion is made of metal base 2, weight reduction can be achieved. Therefore, the inertial force is small, and even if the collector 1 resists the spring and separates from the wire due to frictional vibration during running or a step difference in the contact portion of the trolley wire, there is little separation from the wire. Further, since the lead wire 5 can be connected to the metal plate 2, a connection method such as spot welding or screwing can be freely selected. When the lead wires 5 are connected by spot welding, the connecting portions of the lead wires 5 do not protrude beyond the width dimension of the collector 1. Therefore, even when the conductor spacing is narrow, such as in a multiwire trolley wire, the current collectors can be arranged closely. In addition, when the conductor spacing is wide, lead wire connection may be performed using a conventional crimp terminal 40 as shown in FIG. 17.

In addition, since only the sliding contact body 3 is molded with the current collector material, the molding press needs to be of a smaller capacity compared to conventional molding of the entire body, and the manufacturing equipment is simple. becomes.

Since the trolley current collector of this invention is equipped with a metal base and a sliding contact body integrally molded on the metal base, the sliding contact body is made of an expensive material with excellent wear resistance and arc resistance. It is economical as only the above part is required. Since the metal base and the sliding contact body are integrally molded, their mutual fixation is reliable. In addition, since it is partially constructed from a metal base, it is lightweight and has good line separation characteristics while running. Furthermore, since a metal base is used, there is an advantage that the method of connecting the lead wires can be freely selected.
