Abstract
A solenoid suction type magnetic circuit system for contactors belongs to solenoid (suction type ) magnetic circuit system and consists of a coil, a yoke, a piston sleeve, a connecting rod, a boot, a pressure spring, a guide tube, an armature, a piston ring, a magnetic conduction body and a retaining ring. The coil (1) and the yoke (2) are assembled and then sequentially arranged into the piston sleeve (3), the connecting rod (4), the boot (5), the pressure spring (6), the guide tube (7), the armature (8), the piston ring (9) and the magnetic conduction body (10), the magnetic conduction body (10) and the yoke (2) are fastened via a fastening screw, and an assembled body is locked via the retaining ring (11). The solenoid suction type magnetic circuit system is advanced and reasonable in structural design and obvious and effective in effect, guarantees work reliability, greatly increases work reliability of the contactors, and is applicable to contactors.
Description
Technical field: the utility model relates to helix tube type (suction-type) magnetic circuit system, particularly a kind of contactor screwed pipe suction-type magnetic circuit system.
Background technology: international and domestic contactor product adopts helix tube type (suction-type) magnetic circuit system mostly at present, the armature of helix tube type (suction-type) magnetic circuit system is the electromagnetic force that relies on coil to produce, suction is done rectilinear motion to coil inside, the characteristics of this magnetic circuit system are that stroke is big, suction is big, the requirement of can satisfy the big gap of main contacts preferably, switching large current load.
There is friction of motion in the functional reliability of helix tube type magnetic circuit system owing to be subjected to structural limitations between the metalworks such as armature and magnetic conductor, often the clamping stagnation because of motion causes product function to lose efficacy, and contactor product functional reliability is affected.
Summary of the invention: the purpose of this utility model is to provide a kind of contactor screwed pipe suction-type magnetic circuit system, through optimal design, and this structural design advanced person, the magnetic circuit functional reliability is greatly enhanced.
Formation of the present utility model: form by coil, yoke, piston bush, connecting rod, pole shoe, stage clip, guide pipe, armature, piston ring, magnetic conductor and collar, coil 1 and yoke 2 are assembled, pack into successively again piston bush 3, connecting rod 4, pole shoe 5, stage clip 6, guide pipe 7, armature 8, piston ring 9, magnetic conductor 10, with trip bolt that magnetic conductor 10 and yoke 2 is fastening, with collar 11 assembly is locked.
Compared with the prior art, the utility model structural design advanced person, it is obvious to obtain effect.Through optimal design, according to the sport dynamics principle, motion parts at magnetic circuit system increases piston ring and piston bush, material adopts the less polytetrafluoroethylene of coefficient of friction, the metal friction of motion is isolated fully, piston ring is designed to the automatic tension adjustment structure, reduce motion parts at the volley with the friction of guiding parts, thoroughly solve motion parts and lost efficacy because of the product functionality that clamping stagnation causes.Magnetic circuit system work is more reliable, and whole contactor product reliability is greatly enhanced.
The utility model structural design is rationally advanced, obtains effect obviously, effectively, and the functional reliability of magnetic circuit system is guaranteed, and contactor product functional reliability is greatly enhanced.
Description of drawings: Fig. 1 is the utility model structural representation, and Fig. 2 is the I place partial enlarged drawing of Fig. 1.
1. coils among the figure, 2. yoke, 3. piston bush, 4. connecting rod, 5. pole shoe, 6. stage clip, 7. guide pipe, 8. armature, 9. piston ring, 10. magnetic conductor, 11. collars.
Embodiment: as shown in Figure 1 and Figure 2, coil 1 and yoke 2 are assembled the piston bush 3 of packing into successively again, connecting rod 4, machine boots 5, stage clip 6, guide pipe 7, armature 8, piston ring 9, magnetic conductor 10, with trip bolt that magnetic conductor 10 and yoke 2 is fastening, with collar 11 assembly is locked.
Operation principle: when coil 1 two ends power up, armature 8 is under the effect of electromagnetic attraction, overcome the mechanical counter-force that stage clip 6 produces, move to yoke 2 pole-faces, in motion process, the motion of armature 8 can not rub with guide pipe 7 again, connecting rod 4 is undertaken by piston bush 3 with the guiding of yoke 2, armature 8 moves to yoke pole-face direction with the guiding movement of guide pipe 7 by piston ring 9, all metal frictions of motion are all isolated, product magnetic circuit system functional reliability is effectively improved, and contactor product functional reliability is greatly enhanced, and thoroughly solves the product functionality that causes because of the magnetic circuit clamping stagnation and loses efficacy.
