Description
Technical field
The utility model relates to the relay field, particularly a kind of subminiature relay.
Background technology
Relay is a kind of switching device with Current Control; usually be applied in the automatic control circuit; it is actually a kind of " automatic switch " that removes to control big electric current with less current, so play automatic adjusting, safeguard protection, effects such as change-over circuit in circuit.It is requisite performer in the various automatic control circuits.Continuous development along with electronics industry, (size that generally is meant longest edge is greater than 10mm for subminiature relay, and the relay less than 25mm) because of its have that volume is little, load is big, reliability is high, etc. characteristics, and be widely used on the control apparatus supporting such as automated system, electronic equipment, instrument and meter, communication device and remote control with it.Wherein common a kind of subminiature relay, support, the base plate, the yoke that are arranged on the bobbin bottom that it comprises shell, be solidified as a whole by pedestal and bobbin, place the bobbin endoporus and with fixing iron core, the armature that places iron core top, the movable contact spring in one side of yoke be fixed in static contact group on the pedestal, the movable contact spring of this subminiature relay and with the movable contact spring lead-out tablet be split-type structural, the movable contact spring lead-out tablet is connected with the movable contact spring terminal pin.Since its movable contact spring be connected with riveted way with the movable contact spring lead-out tablet, the conductivity of this subminiature relay movable contact spring and radiating effect all are not very desirable.
The utility model content
Technical problem to be solved in the utility model is: conductivity and the better subminiature relay of radiating effect that a kind of movable contact spring is provided.
The technical scheme in the invention for solving the above technical problem is: a kind of subminiature relay, places the bobbin endoporus and with fixing iron core, the armature that places iron core top, the movable contact spring in one side of yoke be fixed in static contact group on the pedestal at support, the base plate, the yoke that are arranged on the bobbin bottom that it comprises shell, be solidified as a whole by pedestal and bobbin; Described movable contact spring is the bending member of syllogic, and movable contact spring leading portion and movable contact spring stage casing inwardly roughly bend 90 °, and the front end of described movable contact spring leading portion is provided with and described first fixed contact or second fixed contact moving contact movingly; Described movable contact spring stage casing and movable contact spring back segment outwards roughly bend 180 °, and the another side of described movable contact spring stage casing and yoke is fixed, and the free end of described movable contact spring back segment is connected with the movable contact spring terminal pin.
Compared with prior art, advantage of the present utility model is: the movable contact spring of this subminiature relay is the bending member of syllogic, the front end of movable contact spring leading portion is provided with moving contact, one side the fixing of movable contact spring stage casing and yoke, the free end of movable contact spring back segment is connected with the movable contact spring terminal pin.Like this, movable contact spring and movable contact spring lead-out tablet are the bending member of integral type, have better conductivity and thermal diffusivity, and the bending member of integral type is more stable than the structure of the connected mode of riveted joint, and shockproof effect is also better.
As improvement, described movable contact spring leading portion partly is provided with oblique from the inside to the outside perk section away from moving contact.Like this, this perk section makes the adhesive of the moving contact that the movable contact spring leading portion is provided with and bounce-back answer be more prone to, and when no power, can keep movable contact spring to contact with first fixed contact (normally closed fixed contact) all the time.
As further improvement, the free end of described movable contact spring back segment is provided with a bending segment that roughly becomes " L " shape, and the inboard of described bending segment end is connected with the movable contact spring terminal pin.Like this, the location arrangements of the movable contact spring pin of this subminiature relay more reasonable makes that the volume of this relay is little, and structure is compact more.
