Abstract
The invention relates to an electromagnetic relay which comprises an outer shell, an electromagnetic system, a contact system and a pushing clamp, wherein the pushing clamp is arranged between the electromagnetic system and the contact system, one end of the pushing clamp is connected with the armature iron of the electromagnetic system, the other end of the pushing clamp is connected with a moving reed of the contact system, the upper end of the armature iron is clamped in the pushing clamp, the lower end of the armature iron is movably clamped on a coil frame of the electromagnetic system, the upper part of the moving reed is in an F shape, and the cross edge of the pushing clamp is clamped between the two edges of the F-shaped moving reed. The invention has the advantages that: firstly, the F-shaped moving reed is adopted, the invention avoids the complicated technology that the moving reed needs to be provided with hole flanging, and the like, therefore, the whole electromagnetic relay has simple assembly and high production efficiency, is convenient for automation mass production, and also avoids the defect of unstable contact resistance; secondly, the armature iron structure is improved, a pressure spring piece is canceled, the invention eliminates hidden troubles that the shape of the pressure spring piece is complicated, the pressure of the pressure spring is unstable and is easy to clamp, and the like, and the assembly process of the armature iron is simplified.
Description
Technical field
The present invention relates to electromagnetic relay.
Background technology
The development that modern electronic technology is integrated requires the miniaturization of electronic devices and components more, and relay product miniaturization thus, low cost are important trend of its development, needs the structure of existing relay is carried out rationally, designed cleverly for this reason.
The existing relay product generally comprises the push card between pedestal, electromagnetic system, contact system and electromagnetic system and contact system, push card adopts perforate on the movable contact spring with being connected of electromagnetic system, contact system, push card is inserted in the hole of movable contact spring, methods such as movable contact spring hole use flange solve the installation and the mechanism action problem of push card, also there are hidden danger such as relay contact resistance instability in this constitutional detail processed complex, production cost height.The stage clips that adopt are connected more between the armature of electromagnetic system and iron core in addition, stage clip part shape complexity, cost height, and this method production technology is also complicated, has stage clip pressure transient, hidden danger such as easy stuck.
Summary of the invention
Technical problem to be solved by this invention is to overcome the above-mentioned deficiency of prior art and electromagnetic relay is provided, it simplifies the movable contact spring structure, make its produce simple, cost is low, improve the syndeton between push card and movable contact spring again, make push card move back and forth middle difficult drop-off, eliminate hidden danger such as relay contact resistance instability.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
Electromagnetic relay, comprise the push card between shell, electromagnetic system, contact system and electromagnetic system and contact system, push card one end connects the armature of electromagnetic system, the other end connects the movable contact spring of contact system, it is characterized in that: described armature upper end is stuck in the push card, the lower end active card is connected on the bobbin of electromagnetic system, and described movable contact spring top is " F " shape, and the horizontal edge of push card is stuck between two limits of movable contact spring " F " shape.
The one-sided Kai “ of described armature downside Xi " breach, open " Jiong " shape hole on the bobbin accordingly and cooperate ， “ Xi " two horizontal edges of breach are stuck in the horizontal edge in " Jiong " shape hole of bobbin and carry out spacing to the rotation of armature.
The medial surface iron core corresponding position of described shell is provided with one and limits the boss that iron core moves up and down.
Compared with prior art, the invention has the advantages that:
1, adopt " F " shape movable contact spring, avoided movable contact spring need establish complicated technologies such as hole flanging, therefore the assembling of whole electromagnetic relay is simple and easy, production efficiency is high, is convenient to the automation production in enormous quantities, but also has avoided the defective of contact resistance shakiness.
2, improve armature structure, cancelled stage clip spare, eliminated stage clip part shape complexity, stage clip pressure transient, easy hidden danger such as stuck, also simplified the armature assembly process.

Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, the left side of electromagnetic relay is an electromagnetic system, electromagnetic system comprises bobbin 1, iron core 2, armature 3, armature 3 lower ends are limited on the bobbin 1, the upper end then is stuck in push card 4 one ends, the electromagnetic relay right side is a contact system, form by movable spring assembly 5 and quiet spring assembly 6, the other end of the upper end engaging push card 4 of movable spring assembly 5, the electromagnetic system that forms of bobbin 1 and iron core 2 rotates the push card 4 that armature 3 upper ends engages by excitatory and demagnetization thus, moves back and forth that push card 4 drives the movable spring assembly 5 of contact systems and the contact that is switched on or switched off movable spring assembly 5 and quiet spring assembly 6.
5 one-tenth " F " shapes of above-mentioned movable contact spring, about the bottom of " F " shape has two 52,53, be triangle with F shape last slice 51 placed in the middle, like this can be well fixing push card 4 limits.
Above-mentioned movable contact spring " F " shape is spacing with 41 one-tenth semi-surroundings in limit of push card 4, and the ability of its slip-off preventing and vibration proof improves greatly in the reciprocating action process of whole electromagnetic relay mechanism like this.
Lower end one side Kai “ Xi as Fig. 2, Fig. 3, the above-mentioned armature 3 of Fig. 4 " breach 31; cooperates with corresponding " Jiong " v notch v 11 on the bobbin 1; and carry out spacing; iron core 2 cooperates with armature 3; after utilizing the spacing and coil electricity of bobbin 1 top 11 pairs of armature of " Jiong " v notch v iron core 2 formation magnetic force are adsorbed armature; guarantee the stability of its action the rotation of armature 3, this structure structure relatively in the past, saved the hidden danger of quality that complex-shaped stage clip part and assembly technology thereof bring, saved part manufacturing cost and simplified assembly technology.
Show that as Fig. 5 with the boss 71 of an aligning iron core 2,71 pairs of iron cores of boss 2 carry out spacing shell 7 in the inboard, guarantee the structure of whole electromagnetic relay and stablizing of action.
