End is located at the dynamic iron core in lower magnetic conductive cylinder, yoke plate is equipped with above dynamic iron core, between yoke plate lower end surface and dynamic iron core upper surface
It is formed with stroke gap, the upper magnetic conductive cylinder being arranged in a ring is formed on the periphery in stroke gap, dynamic iron core can be in upper magnetic conductive cylinder
It inside pumps, upper magnetic conductive cylinder is mutually fixed with the yoke plate, and dynamic iron core is fixed with catch bar lower end, catch bar upper section
Positioned at yoke plate so that and fixed with movable contact spring, by moving up and down to drive moving up and down for movable contact spring for dynamic iron core so that
Movable contact and stationary contact point contact or disjunction on movable contact spring.
Due to the presence of dynamic iron core and lower magnetic conductive cylinder, bobbin certainly will be made greatly, while in order to guarantee on dynamic iron core energy
Lower movement, the coil turn wound on bobbin is more, so that relay volume is larger, energy consumption is higher, and relay parts
It is more, higher cost.
Summary of the invention
The object of the present invention is to provide a kind of lower, small volume that consumes energy, lower-cost bats to close the normally closed relay of Direct Action Type
Device.
To achieve the above object, the present invention adopts the following technical scheme: Direct Action Type normally closed relay, including shell are closed in a kind of bat
Body, the shell is interior to be equipped with magnetic circuit part, movable contact part and stationary contact part, and the magnetic circuit part includes bobbin and setting
Coil on bobbin, the bobbin are formed with the perforative through slot in left and right, are equipped with iron core in through-hole, and the one of L-shaped yoke
End is fixed with iron core, and the other end of L-shaped yoke is located on the upside of bobbin and matches with armature, and the armature both ends are respectively
It touches end and suction side, the suction side of the armature is located at iron core left or right side, the touch end of the armature is located on yoke
Side is simultaneously located on the downside of catch bar lower end, and the movable contact part includes the movable contact spring being fixed on catch bar and is arranged in movable contact spring
The movable contact of left and right ends, the stationary contact part include static contact spring piece and the stationary contact mutually fixed with static contact spring piece, the stationary contact
It corresponds and is located at below movable contact with movable contact, the movable contact spring is in contact with main spring end, and movable contact spring is in the master
It is moved down under the action of spring, the coil is powered so that the suction side of armature is moved to iron core far from a side end of yoke
It is dynamic, and move up the touch end of armature to drive catch bar and movable contact spring to move up.
The present invention substitutes the movement of dynamic iron core by the movement of armature, so that bobbin is laterally arranged without vertically setting
It sets, is only arranged to reduce the space in relay height, while in bobbin cored, there is no magnetic conduction sleeve, bobbin can be done
It is smaller, the number of turns and volume of coil are smaller, the power consumption smaller diminution to realize relay volume when use.Wherein, armature with
Yoke is connected and fixed mode using the fixed form of armature in conventional clapper type relay.The components of magnetic circuit part of the present invention
Less, manufacture production assembly cost is lower, and adapts to small size shell so that invention relay keeps miniaturization.The present invention
Relay only work as in the case of coil is powered and can just make armature movable so that relay has normally closed function when being not powered on
Energy.Wherein, compressed spring or extension spring can be used in main spring, to guarantee connecing for movable contact and stationary contact in the case of being not powered on
Touching.
Preferably, being connected with several power of returning springs between the movable contact spring and shell, the power of the returning spring one end drag hook is
Connecting pin is simultaneously connect with movable contact spring, and the power of the returning spring other end drag hook is fixing end and rhampotheca on slide bar, the slide bar with
Shell is fixed, and the fixing end of the power of the returning spring is located above movable contact spring.
Wherein, power spring is returned to move up for auxiliary push-rod after being powered, it is quick between quick sound contact to realize
Disjunction.The drag hook for returning power spring upper end is that simultaneously for rhampotheca on slide bar, several power of returning spring upper end drag hooks can be on slide bar for fixing end
Sliding is to carry out self position adjusting, to guarantee the stabilization of movable contact spring.
Preferably, be arranged with pallet on the catch bar, the pallet has up and down through passing through for catch bar
Upper through-hole, and the pallet is mutually fixed with shell, the main spring is set between pallet and movable contact spring, and the main spring is arranged
On catch bar.
The fixation of pallet and shell can be carried out using various ways as needed, for example is formed on shell to pallet
Card slot, or carry out the integrated molding of shell and pallet and manufacture, or pallet dispensing is immobilized in the shell etc..Pallet is for leading
The limit of spring upper end, main spring are set in catch bar and between pallet and movable contact springs.
