Problems solved by technology

[0003] The current electrical switches of electromagnetic relays mainly have the following problems in the control process: usually a plurality of electrical switches are installed inside the protective device, and the closing of the electrical switches usually needs to be controlled separately by the staff. Low, on the other hand, separate control will increase the risk of sparks when the electric sheet contacts, thereby increasing the probability of electric shock for the staff and affecting the safety of users

Embodiment Construction

[0026] Embodiments of the present invention will be described below with reference to the drawings. In the process, in order to ensure the clarity and convenience of illustration, we may exaggerate the width of the lines or the size of the constituent elements in the diagram.

[0027] In addition, the following terms are defined based on the functions in the present invention, and may be different according to the user's or operator's intention or practice. Therefore, these terms are defined based on the entire content of this specification.

[0028] Such as Figure 1 to Figure 8 As shown, an electromagnetic relay includes a protection device 1, an electrical switch 2 and a control device 3; the inside of the protection device 1 is evenly installed with an electrical switch 2 through a clamping method, and a control device is arranged inside the protection device 1 3. The control device 3 cooperates with the electric switch 2; the side wall of the electric switch 2 is symmet...

Abstract

The invention provides an electromagnetic relay. The electromagnetic relay comprises a protection device, an electrical switch and a control device; electrical switches are uniformly mounted in the protection device in a clamping manner, a control device is arranged in the protection device, and the control device is matched with the electrical switches; and sliding blocks are symmetrically arranged on the side wall of the electrical switch, and balls are arranged on the outer walls of the sliding blocks of the electrical switch in a movable connection mode. The problems that in the control process of electrical switches of an existing electromagnetic relay, a plurality of electrical switches are generally installed in a protection device, closing of the electrical switches generally needs to be independently controlled by workers, on one hand, the efficiency is low, and on the other hand, the risk of sparks generated during contact of the electric sheets can be increased through independent control, so that the probability of electric shock of workers is increased, and the safety of users is affected.

Description

technical field [0001] The invention relates to the technical field of electric power engineering, in particular to an electromagnetic relay. Background technique [0002] Electromagnetic relays are generally composed of iron core, coil, armature, contact reed and so on. As long as a certain voltage is applied to both ends of the coil, a certain current will flow through the coil, thereby generating an electromagnetic effect. The moving contact and the static contact (normally open contact) are sucked together. When the coil is de-energized, the electromagnetic suction will disappear, and the armature will return to its original position under the reaction force of the spring, so that the moving contact and the original static contact (normally closed contact) will be released. In this way, it is attracted and released, so as to achieve the purpose of conducting and cutting off in the circuit. [0003] The current electrical switches of electromagnetic relays mainly have ...
