Description
Technical field
The present invention relates to a kind of multibreak contact making device for electromagnetic switchgear, comprise multiple moveable switch contact, described switch contacts can be guided and be fixed by a spring base under the action of the spring in a contact operating element.
Background technology
Electromagnetic switchgear comprise be fixedly arranged on that solenoid in switchgear and yoke and armature form by the magnetic circuit of this solenoid controlled, wherein, the same fixed and arranged of yoke is in shell, and in other words relative to solenoid fixed and arranged, armature is then movable.Armature is connected with the contact holder being provided with moving contact, and these moving contacts come in contact with the fixed contact of same fixed and arranged in shell when switchgear closes.This switchgear also comprises spring or spring base.The all component of electromagnetic switchgear must be clear and definite corresponding each other in geometrical arrangements, and within its time limit in useful life, adopt machinery and electrical arrangement mode reliably.
DT 1 765 920 OS discloses a kind of switchgear, the central authorities that its separate type touches bridge are separately provided with clear and definite contact position, these contact positions are positioned at one and are made up of the material that electric conductivity is good and by the pressing plate of common contact compression spring effect, realize the electrical connection of two tactile bridges whereby.One of them tactile bridge being provided with a tapered contact protuberance for forming clear and definite contact position, another tactile bridge being then provided with two contact protuberances.These tactile bridges relative to pressing plate free movement, thus can touch bridge when tactile bridge bracket motion, particularly can tilt along any direction in switching process.In addition, known contact device is not arranged special in guide the guide member of tactile bridge, therefore, tactile bridge is likely subjected to displacement in the bracket, and this situation especially can occur in installation process.
DE 22 53 918 C3 describes a kind of contact making device for switchgear, this contact making device realizes multiple disconnection by the contact position be arranged in parallel of two tactile bridges, these two tactile bridges are guided by the spring base of contact pressure spring in the operating element of contact, wherein, spring base has the groove transverse to elasticity direction, and tactile bridge can transversely snap in these grooves in the direction of tactile bridge longitudinal direction and engage with spring base.
DE 31 36 354 C2 describes a kind of contact making device for electric switching system, particularly electromagnetic switchgear, be made up of a bending bridge that touches, this tactile bridge is supported by spring base in tactile bridge bracket, can move along the direction of motion together with spring base after overcoming the active force of contact pressure spring, and be connected with state type contact by contact face, this spring base can not be subjected to displacement transverse to this direction of motion, wherein, this tactile bridge is divided into two parts in the vertical, and the width at bending area two ends is all less than Breadth Maximum.
That multibreak switch contact is embodied as bending for the shortcoming of the embodiment of the contact making device of electromagnetic switchgear in prior art, in order to avoid it is subjected to displacement in the operating element of contact.But when adopting bending switch contacts, need larger structure space that break contact just can be avoided to intersect with make contact.In addition, engaging with each other between switch contacts increases installation difficulty.
Summary of the invention
In view of this, the object of this invention is to provide a kind of multibreak contact making device for electromagnetic switchgear, its switch contacts is arranged comparatively compact, can save space, farthest can also simplify installation.
The present invention is in order to reach the solution of above-mentioned purpose for a kind of contact making device with feature described in claim 1.Dependent claims is that the present invention both can apply separately also can the Favourable implementations of connected applications and improvement project.
The present invention is used for the multibreak contact making device of electromagnetic switchgear, comprise multiple moveable switch contact, described switch contacts can be guided and be fixed by a spring base under the action of the spring in a contact operating element, it is characterized in that, described switch contacts has unbending finger-like projections.Electromechanical switchgear (such as contactor or motor starter) realizes the multibreak contact making device of moveable switch contact by arranging parallel moveable switch contact, these switch contacts are preferably fixed between two parties and guided in the operating element of contact under the action of the spring.Switch contacts is bearing in spring base in the mode that can tolerate HI high impact load.This point is realized by the finger-like projections on switch contacts, and this finger-like projections, preferably near the center arrangement of switch contacts, increases the contact-making surface on bearing position whereby.In addition, described finger-like projections snaps in spring base thus stops switch contacts to be subjected to displacement, and this just further enhancing above-mentioned effect.The size that this projection on moveable switch contact adopts makes each current path only need adopt a kind of switch contacts embodiment.For this reason, spring base is installed the bump material can carrying out reliable guiding on bearing position to switch contacts.
In sum, the advantage of contact making device of the present invention is, needs the space taking switch element less, because selected structure does not need switch contacts to bend, and will not engage with each other by switch contacts when installing, this significantly can simplify installation.In addition, the size that spring base adopts makes it both can be used as the spring base of fixing moveable switch contact, also can be used as supporting device of the spring.Described spring base also adopts the structural design of the moveable switch contact electric isolution that these two can be arranged in parallel.
According to the particularly advantageous execution mode of one, described spring base is provided with at least one notch that can snap in for the finger-like projections of described switch contacts, so just can be more effectively fixed on described bearing position by switch contacts.The structural design that described spring base adopts makes it both can in order to have supported described spring in the operating element of described contact, again can in order to support described two moveable switch contacts.
The multibreak contact making device that the present invention is used for electromagnetic switchgear can reduce installation difficulty, because described switch contacts is embodied as linear (namely not bending), thus need not mutually engage, contact making device of the present invention is compact, can save space.
