Embodiment 1

[0031] Depend on figure 1 As shown, the present invention discloses a relay with a switch-type auxiliary contact assembly, including a casing 10, a movable assembly and an auxiliary contact assembly are arranged in the casing, and the movable assembly includes a movable iron core 11, a push rod 12 and a movable spring Sheet 13, the movable iron core 11 is located on the lower side of the yoke iron plate 14, the movable reed 13 is located on the upper side of the yoke iron plate 14, the push rod 12 passes through the yoke iron plate 14, and a U-shaped yoke 15 is provided on the lower side of the yoke iron plate, The U-shaped yoke 15 is provided with a magnetic conducting cylinder 16, a coil bobbin 17 and a coil 18. The yoke plate 14 cooperates with the insulating cover 19 to form a chamber for accommodating the moving and static contacts. The movable contacts on both ends of the upper end face of the reed and the static contacts fixed on the lower end of the lead-out end, the l...

Embodiment 2

[0037] Depend on Figure 5 to Figure 7 As shown, the present invention discloses an auxiliary contact assembly of a relay, including an auxiliary contact switch 2 arranged between the moving reed 13 and the yoke plate 14 for sending the working state of the relay and a switch for triggering the auxiliary contact 2, the movable reed 13 is fixed on the upper end of the push rod 12. After the coil of the relay is energized, the push rod 12 drives the movable reed 13 to rise, so as to keep the trigger 3 away from the auxiliary contact switch 2. The auxiliary contact switch 2 is fixed on the upper side of the yoke iron plate 14 , and the trigger member 3 is fixed with the movable spring plate 13 . Among them, the auxiliary contact switch 2 is a tact switch.

[0038] The trigger 3 is composed of a fixed part 31 , a deformed part 32 and a trigger part 33 , the fixed part 31 is riveted and fixed with the movable spring 13 , the trigger part 33 is used for contacting the button 21 of ...

Abstract

The invention relates to a high-voltage direct-current relay, in particular to a relay with a switch type auxiliary contact assembly. A relay with a switch type auxiliary contact assembly is characterized in that the relay comprises a shell, a movable assembly and the auxiliary contact assembly are arranged in the shell, and the movable assembly comprises a movable iron core, a push rod and a movable reed. The auxiliary contact assembly comprises an auxiliary contact switch used for sending the working state of the relay and a trigger piece used for triggering the auxiliary contact switch, and when the movable assembly moves in the axis direction of the push rod, the trigger piece and the auxiliary contact switch are close to each other or separated from each other. The invention has the advantages of higher use reliability, more convenience in assembly and lower cost.

Description

technical field [0001] The invention relates to a high-voltage direct current relay, in particular to a relay with a switch-type auxiliary contact assembly. Background technique [0002] In order to monitor the working state of the DC relay, auxiliary contacts will be set in the relay, and an external auxiliary contact detection circuit will be installed. The working state of the relay includes: ① the relay is in the normal working state where the dynamic and static contacts are conducting; ② is in the normal working state where the dynamic and static contacts are disconnected; to a fault state where the signal is disconnected but the moving and static contacts are bonded. [0003] The Chinese patent application number 201910258948.X discloses an auxiliary contact structure and a high-voltage DC relay with auxiliary contacts. The auxiliary contact structure includes a U-shaped bracket for installing the main reed, an auxiliary contact lead-out end, an auxiliary contact A r...
