The invention discloses an electromagnetic relay 1 capable of manually controlling electrical opening and closing externally, which comprises a shell 10, a push-pull rod 11 and a relay component 12, wherein the shell 10 is provided with a base 101 and an upper cover 102, the upper cover 102 is sunken to form a slide way 1021, one end of the slide way 1021 is communicated with the inner surface of the upper cover 102, the other end of the slide way 1021 is provided with a convex block 1022, and the section of the convex block 1022 is in a T shape, so that the structure is wide at the top and narrow at the bottom.
The push-pull rod 11 is disposed on the slideway 1021 and can move relative to the upper cover 102, one end of the push-pull rod 11 forms a force application portion 111, the other end forms a hook portion 112 and is disposed in the housing 10 in a penetrating manner, the body of the push-pull rod 11 is recessed to form a slot 113, and a fitting hole 1131 and a sliding hole 1132 which are connected with each other are formed at the bottom of the slot 113, the sliding hole 1132 is in a straight rectangular shape, the size of the fitting hole 1131 corresponds to the size of the protrusion 1022, and the width of the sliding hole 1132 is smaller than that of the fitting hole 1131, so as to facilitate the assembly of the protrusion 1022 and the movement of the push-pull rod 11.
The relay assembly 12 is disposed on the base 101, and has at least one contact spring assembly 121 and a shift lever 122 disposed toward the upper cover 102, the contact spring assembly 121 has at least one fixed contact piece and at least one movable contact piece, one end of the shift lever 122 can directly or indirectly push the movable contact piece to contact with or disconnect from the fixed contact piece, and the other end of the shift lever 122 is mutually fastened to the hook portion 112; after the engaging hole 1131 of the push-pull rod 11 penetrates through the protrusion 1022, the sliding hole 1132 can move relative to the protrusion 1022 and drive the hook portion 112 to move in the housing 10, and when the force-applying portion 111 is stressed, the sliding hole 1132 can move relative to the protrusion 1022, so that the hook portion 112 drives the shift lever 122 to push the contact spring set 121 to form an electrical connection or electrical disconnection state. Thus, by the structure of the push-pull rod 11 and the slide 1021, the push-pull rod 11 can be moved from the outside to make the hook portion 112 of the push-pull rod 11 drive the shift lever 122, and the shift lever 122 can further drive the movable contact piece to contact with or disconnect from the fixed contact piece, thereby achieving the effect of directly controlling the electrical state of the electromagnetic relay 1 from the outside. Thus, for example, when the replacement or maintenance is to be performed, the push-pull rod 11 can be used to control and ensure the electromagnetic relay 1 to be in the power-off state for the subsequent processing.
Further, the fitting hole 1131 can be one of a circle or a square to facilitate assembling with the protrusion 1022, and in the embodiment, the fitting hole 1131 is a square as an example.

In addition, in a preferred embodiment, the electromagnetic relay 1 may further include a rotating bridge 13, the rotating bridge 13 has a body 131 and a first rotating plate 1311 and a second rotating plate 1312 extending from two sides of the body 131, and preferably, the body 131 of the rotating bridge 13 may have magnetism to drive the rotating bridge 13 to operate through magnetic control. Wherein, when the number of the fixed contact pieces and the number of the movable contact pieces are two, the fixed contact pieces and the movable contact pieces are respectively defined as a first fixed contact piece 1211 and a first movable contact piece 1212, and a second fixed contact piece 1213 and a second movable contact piece 1214; a first engaging groove 1221 and a second engaging groove 1222 are disposed at one end of the driving lever 122, the first engaging groove 1221 is engaged with the first movable contact pad 1212, the second engaging groove 1222 is engaged with the first rotating pad 1311, and the second rotating pad 1312 is directly or indirectly engaged with the second movable contact pad 1214; when the driving lever 122 is forced, the contact or disconnection between the first movable contact 1212 and the first fixed contact 1211 can be synchronized with the contact or disconnection between the second movable contact 1214 and the second fixed contact 1213. In this embodiment, the relay assembly 12 may be provided with two corresponding fixed contact pieces and movable contact pieces, and the first rotating piece 1311 and the second rotating piece 1312 of the rotating bridge 13 are used to synchronously control the opening and closing of the first movable contact piece 1212 and the second movable contact piece 1214 relative to the first fixed contact piece 1211 and the second fixed contact piece 1213. In the embodiment, the second rotating plate 1312 of the rotating bridge 13 can be directly or indirectly fastened and connected with the second movable contact piece 1214, for example, the second rotating plate 1312 of the rotating bridge 13 is fastened and connected at one end of an extending arm 14, and the other end of the extending arm 14 is fastened and connected with the second movable contact piece 1214, so that the second rotating plate 1312 of the rotating bridge 13 is fastened and connected with the second movable contact piece 1214 through the extending arm 14, which is helpful for improving the stability of the second movable contact piece 1214 during operation.

In a preferred embodiment, when the electrical state of the electromagnetic relay 1 needs to be adjusted, the force application portion 111 of the push-pull rod 11 is pulled outward to move the sliding hole 1132 relative to the protrusion 1022, so that the hook portion 112 moves in the housing 10 to drive the shift lever 122 upward, and the second engaging groove 1222 of the shift lever 122 drives the first rotating plate 1311 to move upward, and the rotating bridge 13 rotates. At this time, the first movable contact piece 1212 is driven by the first slot 1221 connected thereto to disconnect with the first fixed contact piece 1211, and the second movable contact piece 1214 is synchronously disconnected with the second fixed contact piece 1213 in response to the second rotating piece 1312 of the rotating bridge 13, so that the electromagnetic relay 1 is in a non-conducting state, and the electrical state of the electromagnetic relay 1 can be switched from fig. 3 to fig. 4. On the contrary, to turn the electromagnetic relay 1 to the on state, the push-pull rod 11 is pushed to make the sliding hole 1132 move relative to the protrusion 1022, so that the hook portion 112 drives the shift lever 122 downward. At this time, the second card slot 1222 of the shift lever 122 drives the first rotating plate 1311 to move downward, and the rotating bridge 13 rotates, so that the first movable contact piece 1212 can contact the first fixed contact piece 1211 in response to the first card slot 1221 connected to the first movable contact piece 1212, and synchronously contact the second movable contact piece 1214 with the second fixed contact piece 1213 in response to the second rotating plate 1312 of the rotating bridge 13, so as to enable the electromagnetic relay 1 to be in a conducting state, and then the state is switched to the state shown in fig. 3 as shown in fig. 4.
