Description

Small high-power relay
Technical field
The utility model relates to a kind of relays, and in particular to a kind of small high-power relay.
Background technique
Currently, electromagnetic relay is a kind of using extensive electronic component, it is applied to household electrical appliance, automobile, industry control The fields such as system, electric system, communication device.With the development of low-voltage electrical apparatus, electromagnetic relay using more and more extensive, to electricity The requirement of magnetic relay is also higher and higher.Traditional design pattern is costly, the period is long, and when electromagnetic relay steady operation Temperature rise is an important parameter in electromagnetic relay design production, directly affects stability and the service life of electromagnetic relay. The unreasonable structural design of existing electromagnetic relay, which increases in the presence of temperature, performance is unreliable, structure is not compact Defect.
Summary of the invention
The purpose of the utility model is to overcome the defect of the prior art, provide that a kind of structure is simple, compact-sized, performance Small high-power relay reliable and stable, temperature rise is low.
To achieve the above object, the utility model uses a kind of small high-power relay, including bottom plate, setting in bottom plate On housing, iron core, coil, bobbin, yoke, armature, the tension spring being arranged between yoke and armature, be linked with armature Movable contact spring, static contact, correspond on the movable contact spring and be provided with conductive sheet at static contact, be provided on one end of the conductive sheet The movable contact matched with the stationary contact on static contact, the upward bending of the other end of conductive sheet and is formed with interconnecting piece, interconnecting piece It is connected with copper litz wire between yoke, several grooves, the copper litz wire are distributed on the upper surface of the interconnecting piece One end spot welding be connected on groove, the other end spot welding of copper litz wire is connected on yoke.
The beneficial effect of above structure is: copper litz wire is connected between conductive sheet and yoke, copper litz wire can play Shunting function, strengthening electric current ducting capacity guarantee that the temperature rise of product is low, and are provided on the interconnecting piece of conductive sheet and copper litz wire The groove of spot welding connection, it is more reliable to ensure that copper litz wire is connect with conductive sheet, enhances its electric conductivity.To which this is small-sized big Power relay has the advantages that structure is simple, compact-sized, stable and reliable for performance, temperature rise is low.
Particularly, it is corresponded on the bobbin and is provided with L-shaped insulating barrier between coil and yoke, it is described It is corresponded on bobbin and is respectively arranged with card slot at the both ends of insulating barrier, the both ends of the insulating barrier are fastened on card slot respectively Clamping engagement that is interior and constituting insulating barrier and bobbin.Be provided on bobbin the insulation that separates coil and yoke every Plate improves the insulation performance of the relay, and insulating barrier is connect by the way of being engaged by clamping with bobbin, convenient for insulation The assembly of partition and bobbin improves the assembly efficiency of product.
Detailed description of the invention
Fig. 1 is the utility model embodiment exploded view.
Fig. 2 is the utility model embodiment cross-sectional view.
Specific embodiment
As shown in Figure 1, 2, the utility model embodiment is a kind of small high-power relay, including bottom plate 10, setting exist Housing 11, iron core 12, coil 13, bobbin 14, yoke 15, armature 16 on bottom plate 10, setting yoke 15 and armature 16 it Between tension spring 17, the movable contact spring 18, the static contact 19 that are linked with armature 16, correspond at static contact 19 on the movable contact spring 18 It is provided with conductive sheet 20, the movable contact matched with the stationary contact 191 on static contact 19 is provided on one end of the conductive sheet 20 201, the upward bending of the other end of conductive sheet 20 and it is formed with interconnecting piece 202, copper volume is connected between interconnecting piece 202 and yoke 16 Line 21 is knitted, several grooves 203, one end spot welding of the copper litz wire 21 are distributed on the upper surface of the interconnecting piece 202 It is connected on groove 203, the other end spot welding of copper litz wire 21 is connected on yoke 16.As shown in Fig. 2, the bobbin 14 L-shaped insulating barrier 22 is provided between upper corresponding coil 13 and yoke 15, on the bobbin 14 corresponding insulation every Card slot 141 is respectively arranged at the both ends of plate 22, the both ends of the insulating barrier 22 are fastened in card slot 141 respectively and constitute The clamping engagement of insulating barrier 22 and bobbin 14.The insulating barrier for separating coil and yoke is provided on bobbin, Improve the insulation performance of the relay, and insulating barrier is connect by the way of being engaged by clamping with bobbin, convenient for insulation every The assembly of plate and bobbin improves the assembly efficiency of product.
Copper litz wire is connected between conductive sheet and yoke, copper litz wire can play shunting function, strengthening electric current conducting Ability guarantees that the temperature rise of product is low, and is provided with the groove connecting with copper litz wire spot welding on the interconnecting piece of conductive sheet, ensure that Copper litz wire connect more reliable with conductive sheet, enhances its electric conductivity.To which the small high-power relay has structure letter Advantage single, compact-sized, stable and reliable for performance, temperature rise is low.
