Description

Improved relay construction

Technical field

The present invention relates to a kind ofly at the designed action supplementary structure of electromagnetic type relay, in when action, wherein shell fragment can switch really, relates in particular to a kind of improved relay construction in order to electromagnetic type relay.

Background technology

Relay is a kind of Electronic Control Unit, it has control system (claim not only input circuit) and Be Controlled system (but also claiming output loop), relay is applied in the automatic control circuit usually, its characteristic utilizes the little curtage of input coil to remove a kind of " automatic switch " of electric current in the control circuit, therefore, all be to shoulder application such as automatic adjusting, safeguard protection, change-over circuit usually at circuit relay electrical equipment;

According to structure and operating characteristic, relay generally all is made up of input sensing mechanism and output executing mechanism two parts, input sensing mechanism is the variation that is used to react input variable, output executing mechanism is according to being in the contact deciliter mode as the actuating of relay for the relay that contact is arranged, according to being conducting with semiconductor subassembly for contactless relay, blocking-up is as the mode of the actuating of relay, relay has the input-output characteristic of jump, mean when relay receives an input signal, if this input signal is during less than relay preset action value, this relay then is failure to actuate, when input signal reaches the preset action value, relay then moves, the circuit junction that is connected in the relay output executing mechanism fades to from zero immediately and meets required signal current potential, and after the actuating of relay, if input signal continues decay downwards by height point, its operating characteristic of output executing mechanism can't be back to zero point with linear mode, but the moment when input signal decays to less than operating value, relay i.e. action at once makes the output executing mechanism vanishing;

Relay can be divided into electromagnetic type relay, temperature-sensitive dry-reed relay, solid-state relay etc. according to architectural feature, wherein electromagnetic type relay generally is made up of structures such as iron core, coil, magnetic poles, add certain voltage by the coil two ends, the electric current that makes in the coil to be flow through produces galvanomagnetic effect, magnetic pole can overcome the pulling force of return spring and inhale to iron core, promptly can be used as the execution action of circuit turn-on, switching.

See also shown in Figure 7, it is an existing electromagnetic type relay structure, its relay inside includes an input circuit 41, an output loop 42, a magnetic pole 43 and an inserted sheet 44, wherein this input circuit 41 is as linking the magnetic force that coil groups (not shown) that external power makes relay inside produces absorption magnetic pole 43, so makes magnetic pole 43 influenced by coil groups and switched by external power control;

Output loop 42 is positioned at relay inside and has one first output contact 421, one second output contact 422, an and shell fragment 423 that is arranged in 422 of first output contact 421 and second output contacts, should middle shell fragment 423 be to present the normality Elastic Contact wherein with first output contact 421, these inserted sheet 44 1 ends are to be provided with magnetic pole 43, and the other end is resisted against middle shell fragment 423;

Whereby, when the external power of input circuit 41 1 ends makes coil groups produce absorption to magnetic pole 43, this magnetic pole 43 is subjected to the change action that magnetic produces promptly to drive inserted sheet 44 synchronously, makes in inserted sheet 44 pushing and pressing shell fragment 423 break away from first output contact 421 and changes contact second output contact 422 into.

Though having, existing electromagnetic type relay is applied to the control effect that circuit switches, yet untrue shortcoming but may switch after long-term the use, when shell fragment is promoted by inserted sheet in the cause, be to utilize self elasticity to produce the bending of deflection slightly, and then do the switching that contacts of first output contact and second output contact, after relay carried out change action for a long time, wherein may to produce structure tired for shell fragment, and then uncertain when shell fragment desires to give up the throne back first output contact in causing.

In view of easily producing, the aging back of existing electromagnetic type relay structure switches untrue shortcoming, the inventor promptly releases a kind of improved relay construction, it is one at the designed action supplementary structure of electromagnetic type relay, when moving, wherein shell fragment can switch really in order to electromagnetic type relay.

Summary of the invention

Technical problem underlying to be solved by this invention is, overcome the above-mentioned defective that prior art exists, and a kind of improved relay construction is provided, it is at the designed action supplementary structure of electromagnetic type relay, when moving, wherein shell fragment can switch really in order to electromagnetic type relay.

For reaching aforementioned creation purpose, the present invention's " improved relay construction " includes a base, and be arranged at input circuit, coil groups, output loop, magnetic pole and the inserted sheet of base, wherein this input circuit is and the coil groups electrically connect, this coil groups is to be connected the magnetic force that produces the absorption magnetic pole with external power by input circuit, so this magnetic pole can be influenced by coil groups, switches by external power control;

Output loop is positioned at base inside and has one first output contact, one second output contact, an and shell fragment that is arranged between first output contact and second output contact, should middle shell fragment be to present the normality Elastic Contact wherein with first output contact, this inserted sheet one end is and the magnetic pole setting, the other end is resisted against middle shell fragment, and this inserted sheet have pass in shell fragment and present the inserted sheet additional ribs of left-hand thread kenel with middle shell fragment;

Whereby, when the external power of input circuit one end makes coil groups produce absorption to magnetic pole, the change action that this magnetic pole is produced by magnetic promptly drives inserted sheet synchronously, make in the inserted sheet pushing and pressing shell fragment break away from first output contact and change contact second output contact into, when the external power deficiency of input circuit one end made coil groups produce absorption to magnetic pole, shell fragment can be by the mode that self elastic force and inserted sheet left-hand thread drive first output contact of giving up the throne back in this.

Aforementioned " improved relay construction " includes an enclosing cover of putting with base cover, but the structure by this enclosing cover protection relay inside.

Aforementioned inserted sheet has an inserted sheet oral area, and this base has and stretches into the inserted sheet oral area with the base protuberance as restriction inserted sheet maximum moving distance.

Shell fragment has for what the inserted sheet additional ribs placed and wears mouth in aforementioned, the rank of supporting that have the single order stratiform between this inserted sheet and inserted sheet additional ribs, and should be to the rank entire area greater than wearing mouth.

Aforementioned base has one and supports sheet for what magnetic pole was replaced.

The invention has the beneficial effects as follows that it is at the designed action supplementary structure of electromagnetic type relay, when moving, wherein shell fragment can switch really in order to electromagnetic type relay.
