Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. It should be apparent that the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1:

as shown in fig. 1 to 3, a trolley wire connection device includes a contact assembly disposed between the ends of two trolley bars 10 (the trolley bars 10 may be selected from any one of copper bars, aluminum bars, or other electric conductors, and a plurality of trolley bars 10 form a trolley wire), the lower side of the contact assembly simultaneously abuts against the upper surfaces of the ends of the two trolley bars 10, the contact assembly and the ends of the two trolley bars 10 are covered by a housing 20, the two ends of the housing 20 are open, the two trolley bars 10 extend to the outside of the two ends respectively through the openings, the lower side of the housing 20 is provided with a slot 21 for allowing an electric brush (not shown in the drawings) to slide along the lower surface of the two trolley bars 10 in the slot 21 to obtain electricity, and the upper side of the housing 20 is provided with a fastener.

Further, connect the pressure subassembly and include fishplate bar 30, play piece board 40, the clamp plate 50 that stack up from bottom to top, the lower surface of fishplate bar 30 and the tip upper surface of two wiping strips 10 touch, and the upper surface of clamp plate 50 is contradicted with the lower extreme of fastener 60.

Furthermore, the two sides of the middle portions of the spring plate 40 and the pressing plate 50 are respectively provided with a positioning notch 41, and the positioning notch 41 is matched with the protruding point 22 (for example, a protruding strip) arranged inside the housing 20. The spring plate 40 is a W-shaped bend and the fastener 60 is a plurality of (e.g., two) m-screws (preferably hexagonal socket head cap screws). The W-shaped bending of the elastic sheet plate 40 is matched with two meter screws, so that the stability is better, and the stress of the two sliding contact strips 10 is balanced.

Further, the lower side of the housing 20 is provided with a corner 23 to hook the lower side edges of the ends of the two wiping strips 10.
