Abstract

<P>PROBLEM TO BE SOLVED: To provide a slider coupling device capable preventing fatigue fracture of a trolley wire without directly transmitting shocks caused by collision to an outlet side trolley wire even when a pantograph collides with a part in a vicinity of a distal end part of an outlet side slider. <P>SOLUTION: The slider coupling device 1 comprises a body 2, a pair of slider supporting members 3, and a shock-absorbing coupling mechanism 4. The body 2 has an ear 5 to hold a trolley wire T2 on a lower part thereof. The pair of slider supporting members 3 adjacent to both sides of the body 2 have an ear 6 to hold a slider 33 on the lower part thereof. The shock-absorbing coupling mechanism 4 couples the slider supporting members 3 with the body 2. The shock-absorbing coupling mechanism 4 prevents the generation of bending distortion of the trolley wire T2 by relatively displacing a holding part by the ears 6 and 16 with respect to the body 2 when the slider 33 is subjected to shocks of a pantograph. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a train line in an AC electrification section, in which two power supply phases are the same but two sections electrically insulated from each other are connected to each other. The present invention relates to a coupling device for connecting an outlet trolley wire located between sliders.
[0002]
[Prior art]
One example of a conventional in-phase section insulator is shown in FIGS. A section insulator 31 for insulating and connecting both sections is installed at the boundary between the section A where the power is to be partially cut off and the other section B as necessary on the train line of the AC electrification section. This section insulator 31 is called an in-phase section insulator because the power supply phases of both sections A and B to be insulated are in phase. The illustrated in-phase section insulator 31 has directionality, and the train travels from right to left in FIGS. 6 and 7 (the right side is referred to as an entrance side, and the left side is referred to as an exit side). Sliders 32 and 33 are attached to the section insulator 31 on both the entrance side and the exit side in order to slide the pantograph smoothly. As shown in FIG. 7, the entrance-side slider 32 has a shape in which a pair extends right and left, which is a direction orthogonal to the extension of the train line, and is separated from the entrance-side trolley line T1 at the center between the two by a separator. Are combined. On the other hand, the exit-side slider 33 is disposed at a small interval on both the left and right sides of the exit-side trolley wire T2 so that the sliding surface thereof is slightly lower than the sliding surface of the trolley wire T2 (FIG. 8). Is connected to the trolley wire T2 by a connecting device 35 referred to as a trolley wire.
The entrance-side slider 32 is slightly pushed up when passing through the pantograph, so that the entrance-side slider 32 is arranged slightly lower (a height difference of 20 mm to 40 mm) with respect to the exit-side slider 33 so that the pantograph does not collide with the tip of the exit-side slider 33. Adjusted. However, if the elevation of the inlet-side slider 32 is larger than this height difference, or if the height difference is not properly adjusted, the pantograph collides near the distal end portion C of the outlet-side slider 33, and the arrow D direction Bending strain is applied. This strain is transmitted to the outlet-side trolley wire T2 via the connection ear 35, and the trolley wire T2 is likely to be fatigue-ruptured at the connection portion of the connection ear 35.

[Problems to be solved by the invention]
SUMMARY OF THE INVENTION An object of the present invention is to provide a slider coupling capable of preventing fatigue breakage of a trolley wire even if the pantograph collides with the vicinity of the tip of the exit-side slider, without mitigating the impact and directly transmitting the impact to the exit-side trolley wire. It is to provide a device.
