The contact plate (2) comprises a driving end (21) and moving contact segments (22), the driving end (21) is provided with driving points (211), and the moving contact segments (22) are uniformly distributed in a circular array by taking the driving points (211) as the circular center; the moving contact segments (22) are respectively provided with moving contacts (221), and the static contact terminals (4) are respectively provided with static contacts (41); contact pressure springs (3) are respectively arranged between the moving contacts (221) and the static contacts (41), and driving pressure springs (6) are respectively arranged between electromagnetic iron cores of the solenoid assemblies (5) and the driving points (211); and all the moving contacts (221) are connected in series. The electromagnetic relay is provided with the contact pressure springs and the driving pressure springs to prevent moving contact terminals from making contact with the static contact terminals in an inoperative state, and arrangement of the multiple static contact terminals enables normal use of the relay when individual static contact is damaged.
Description
Technical field
The utility model relates to electromechanical engineering technical field, relates in particular to a kind of electromagnetic relay.
Background technology
Relay is a kind of electric control device, is conventionally applied in the control circuit of automation.It is actually the one " automatic switch " of going to control large electric current running with little electric current, can in circuit, play the effects such as automatic adjusting, safeguard protection, change-over circuit.Electromagnetic relay is the one in some relays.Conventional electromagnetic relay is all to adopt one group of dynamic/static contact, and in the time that this dynamic/static contact damages, this electromagnetic relay also just cannot use, thereby causes whole electromechanical structure normally to work, and need to change could be from new work after electromagnetic relay.And, can under non operating state, contact because some reason causes dynamic/static contact, cause the effect out of hand of this electromagnetic relay.
Utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is to provide a kind of stage clip that utilizes and separates dynamic/static contact under non operating state, reaches and neither affect relay use and extend again the relay electromagnetic relay in useful life to increase multiple removable fixed contacts and solenoid.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of electromagnetic relay, it comprises jacket (1), touch panel (2), fixed contact (4) and solenoid assembly (5), described touch panel (2) comprises drive end (21) and moving contact section (22), drive end (21) is provided with drive point (211), taking drive point (211), as the center of circle, rounded array is uniformly distributed multiple moving contact sections (22), this moving contact section (22) is provided with moving contact (221), and fixed contact (4) is provided with fixed contact (41); Between moving contact (221) and fixed contact (41), be provided with contact stage clip (3), between the electromagnetic core of solenoid assembly (5) and drive point (211), be provided with and drive stage clip (6); All moving contacts (221) series connection.
Wherein, fixed contact (41) is all connected.
Wherein, fixed contact (41) is all in parallel.
Wherein, the space in jacket (1) and all structures copy portion taking the table plane of described touch panel (2) as the plane of symmetry.
Wherein, fixed contact (4) and solenoid assembly (5) can be dismantled and change.
(3) beneficial effect
Compared with prior art, the utility model is established contact stage clip and is driven stage clip, can prevent that the dynamic/static contact under non operating state from contacting; Be provided with multiple fixed contacts, still can normally use after causing indivedual fixed contacts to damage; Wherein, fixed contact is all connected, and can allow electromechanical equipment also can normally work only having in an effective situation of fixed contact; Wherein, fixed contact is all in parallel, can allow this electromagnetic relay control multiple electromechanical equipments simultaneously; Be provided with two solenoids, still can normally use after causing one of them solenoid to damage; Fixed contact and solenoid can be dismantled separately, not only convenient but also can extend useful life of relay.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
The structure of the utility model electromagnetic relay as shown in Figure 1, Figure 2 and Figure 3, this electromagnetic relay comprises jacket 1, touch panel 2, fixed contact 4 and solenoid assembly 5, described touch panel 2 comprises drive end 21 and moving contact section 22, drive end 21 is provided with drive point 211, taking drive point 211, as the center of circle, rounded array is uniformly distributed multiple moving contact sections 22, this moving contact section 22 is provided with moving contact 221, and fixed contact 4 is provided with fixed contact 41; Between moving contact 221 and fixed contact 41, be provided with contact stage clip 3, between the electromagnetic core of solenoid assembly 5 and drive point 211, be provided with and drive stage clip 6; All moving contacts 221 are connected.The utility model is established contact stage clip and is driven stage clip, can prevent that the dynamic/static contact under non operating state from contacting; Be provided with multiple fixed contacts, still can normally use after causing indivedual fixed contacts to damage.In addition, baffle plate is set around touch panel, makes touch panel only to move both vertically, can prevent that sound contact from departing from and causing contacting.
In the present embodiment, fixed contact 41 is all connected, and can allow electromechanical equipment also can normally work only having in an effective situation of fixed contact.
In the present embodiment, fixed contact 41 is all in parallel, can allow this electromagnetic relay control multiple electromechanical equipments simultaneously.
As shown in Figure 4, in the present embodiment, the space in jacket 1 and all structures, taking the table plane of described touch panel 2 as the plane of symmetry copies portion, cause this electromagnetic relay to have two solenoid assemblies.The utility model is provided with two solenoid assemblies, still can normally use after causing one of them solenoid to damage.
In the present embodiment, fixed contact 4 and solenoid assembly 5 can be dismantled and change.Fixed contact of the present utility model and solenoid can be dismantled separately, not only convenient but also can extend useful life of relay.
These are only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
