Description

Technical Field

[0001] The utility model relates to the technical field of traffic signal control, in particular to a traffic signal magnetic driving mechanism. Background Art

[0002] As the congestion of urban roads becomes increasingly serious, intelligent signal systems have been widely promoted. However, for high-power traffic signal systems, traditional magnetic drive mechanisms are still required for driving. The magnetic drive mechanism requires the electromagnetic coil to generate electromagnetic force to attract the action mechanism to realize the conversion of the signal system. The coil skeleton of the existing electromagnetic coil is provided with an annular winding groove along the circumference of the outer circle of one end of the skeleton. After the enameled wire is wound and connected with the wire by soldering, it is placed in the winding groove, and the enameled wire and the wire are tied and fixed with a thin rope. However, during the bundling and fixing process, because the winding groove is annular, the enameled wire and the wire are straight cylindrical after soldering, and they do not fit the inner ring of the winding groove. When they are tied and fixed on the inner ring of the winding groove, the welding position of the enameled wire and the wire is deformed and stressed by the bundling force, which increases the risk of fracture at the welding point. In addition, since the traffic signal system is generally installed outdoors, it is affected by the dual influence of bad weather and road vibration, which causes axial and radial displacement at the welding point, further reducing the reliability of the magnetic drive mechanism.

[0037] refer to Figure 1 , 3 The fixing mechanism of this embodiment includes a bolt 5, a nut 17, an insulating cover sheet 16 and a gasket 18; one end of the bolt 5 is screwed to the first end of the magnetic core 19, and the insulating cover sheet 16 and the gasket 18 are sequentially inserted into the bolt 5. When the traffic signal magnetic drive mechanism is in use, the insulating cover sheet 16 is in contact with the outer side surface of the first boss 3; the nut 17 is used to be screwed to the bolt 5 when the traffic signal magnetic drive mechanism is installed, and to fix the insulating cover sheet 16 and the gasket 18.

[0038] Preferably, the diameter of the insulating cover sheet 16 is equal to the diameter of the first boss 3, the diameter of the gasket 18 is smaller than the diameter of the insulating cover sheet 16, and the diameters of the stationary contact 6 and the gasket 18 are larger than the diameter of the through hole.

[0039] In practical applications, since the enameled wire 4 has two joints, in specific implementation, the lead-out wire hole includes a first lead-out wire hole 7 and a second lead-out wire hole 8, and the first lead-out wire hole 7 and the second lead-out wire hole 8 are respectively provided to penetrate the two ends of the enameled wire 4.
