The invention relates to the technical field of railway turnout switch machines, and discloses a parallel circuit contact group for a railway switch machine, which comprises a first binding post and a second binding post arranged on a static contact block, and a double-ring movable contact group arranged on a movable contact block, and is characterized in that the double-ring movable contact group is provided with an upper movable point ring and a lower movable point ring; the first binding post and the second binding post are respectively provided with a contact piece, the contact pieces extend towards one side of the double-ring movable contact set, the middle of the side, close to the double-ring movable contact set, of each contact piece is slotted to form an upper contact and a lower contact, and the upper contact and the lower contact are in contact with the upper movable point ring and the lower movable point ring respectively. According to the invention, the contact group is designed into a double-circuit form of a parallel circuit, so that the situation of simultaneous fault of the double circuits can occur with extremely low probability, the defects of single-point contact and insufficient reliability of a single circuit are overcome, and the electrical fault probability of the existing product is reduced.

    本发明涉及铁路道岔转辙机技术领域,公开了一种铁路转辙机用并联电路接点组,包括置于静接点块上的第一接线柱与第二接线柱、置于动接点块上的双环动接点组,所述双环动接点组上安装有上动点环、下动点环,所述第一接线柱和第二接线柱上均安装一个接点片,所述接点片向双环动接点组一侧延伸,所述接点片靠近双环动接点组的一侧中间开缝形成上接点、下接点,所述上接点、下接点分别与上动点环、下动点环接触。本发明将接点组设计成并联电路的双电路形式,极小概率会出现双电路同时故障的情形,解决了单点接触和单电路可靠性不足的缺点,降低了现有产品的电气故障概率。
