Embodiment 1

[0026] Embodiment 1: The contactor is composed of a static contact system and a dynamic contact system. The static contact system includes: static contact piece 4, support piece 5, solder 6, support seat 7, substrate 8, terminal pin 9, fixed piece 10 and fixed nut 11; the dynamic contact system includes: a mandrel 12, a push plate 13, an outer insulating sleeve 14, a moving contact piece, an insulating bushing 16, a mounting ring, an inner insulating sleeve 19 and a fixed sleeve 20, wherein the moving contact piece is provided with 2N pieces, 8 pieces in this embodiment, are distributed on an octagonal cylindrical surface with a mutual interval of 45°, and two parallel moving contacts are connected with the installation ring to form a moving contact assembly. Since the positions of the four installation rings are different , and there is also a difference in height between the connection points with the moving contact piece, which respectively constitute 4 moving contact piece ...

Embodiment 2

[0033] Embodiment 2: The difference between the structure of this embodiment and Embodiment 1 is that N is 3, that is, there are 6 moving contacts arranged in a hexagonal column shape, and the corresponding components matched with other moving contacts are also in a hexagonal shape. layout.

Embodiment 3

[0034] Embodiment 3: The difference between the structure of this embodiment and Embodiment 1 is that N is 6, that is, there are 12 movable contacts arranged in a dodecagonal column shape, and the corresponding components matched with other movable contacts are also in accordance with the twelve-sided polygon layout.

Abstract

The invention discloses a travel switch contactor with multipath signals. The travel switch contactor comprises static contacts (4) and moving contacts. The travel switch contactor is characterized inthat there are 2N moving contacts and all the moving contacts are arranged on the same outer circumference of the shaft core (12) and parallel to the axis. N installing rings sleeve on the shaft core(12). Each installing ring is connected with two parallel moving contacts. One end of each static contact (4) is fixed on a support base (7), and one end is in contact with the surface of one movingcontact, wherein N is a natural number. The arrangement form of the contact group of the contact system is changed and the backup of the contact group number is increased so as to improve the workingreliability of the control system.

Description

technical field [0001] The invention relates to a travel switch contactor. Background technique [0002] With the continuous upgrading and improvement of the reliability requirements of modern aerospace control systems, the output of the travel switch is required to have multiple signals so that the control system can accurately identify the flight status of the aircraft and provide a basis for judgment for the operation command system. As a travel switch for space system signals, the success or failure of its work directly determines the success or failure of the system to perform tasks. Such as figure 1 As shown in the figure, it is a schematic diagram of the contact principle of the traditional limit switch. The cylindrical movable contact 1 and 4 symmetrically distributed contact pieces 2 are simultaneously in sliding contact. The movable contact 1 and the push column 3 of this structure are rigidly fixed. Linkage. When the push column 3 is respectively subjected to t...
