Abstract
The utility model discloses a novel sealed alternating current contactor, comprising a base, a substrate, a rocker arm, an electromagnetic device, a vacuum arc extinguish chamber, a rectifying device and an auxiliary contact. The novel sealed alternating current contactor is characterized in that the rectifying device and the auxiliary contact are packaged in the base by a rear cover, the vacuum arc extinguish chamber is packaged in the substrate by a top cover, and a contact wiring terminal of the auxiliary contact is connected on a wiring seat. The alternating current contactor is changed to be of a package structure, and is small in volume, thereby being convenient to be selected by a drawer type switch cabinet; the rectifying device, the auxiliary contact and the vacuum arc extinguish chamber are packaged in the base and the substrate, so that the contactor is good in safety performance, and long in service life, and the phenomena that the vacuum arc extinguish chamber is damaged caused by accidental collision or the contact of the vacuum arc extinguish chamber is poor since impurities enter into a moving end of the vacuum arc extinguish chamber can be avoided; and the contact wiring terminal of the auxiliary contact is connected on the wiring seat by a lead wire, so that the novel sealed alternating current contactor is convenient for a user to wire.
Description
Technical field the utility model belongs to the A.C. contactor technical field, relates to a kind of novel closed-type A.C. contactor.
The A.C. contactor of background technology prior art is product at the beginning of the eighties mostly; Like CKJ5 low-voltage alternating-current contactor; It comprises base, pedestal, rocking arm, calutron, vacuum interrupter, rectifying device, auxiliary contact and junction block; Vacuum interrupter is that dynamic and static main contact is encapsulated in the ceramic case internal fixation, and the state that is evacuated, and electric arc is extinguished fast.The A.C. contactor of this structure; The conductive pieces that exposes on it is too many; Vacuum tube, capacitor, rectifier diode and auxiliary contact etc. like rectifying device are installed in surface of shell, damaged in collision very easily, and extraneous greasy dirt, dust and other impurities is also as easy as rolling off a log to pollute or corrodes vacuum tube, rectifier diode, electric capacity etc.; Influence its useful life, and overall dimension is bigger.
The purpose of summary of the invention the utility model is to solve prior art to have the technical problem that useful life is short, volume is bigger.A kind of novel closed-type A.C. contactor is provided.
For realizing above-mentioned purpose; The closed A.C. contactor of the utility model; It comprises base, pedestal, rocking arm, calutron, vacuum interrupter, rectifying device and auxiliary contact; Its main points are that said rectifying device and auxiliary contact are encapsulated in the base through bonnet, and said vacuum interrupter is encapsulated in the pedestal through top cover, and the contact binding post of auxiliary contact is connected on the junction block.
Said vacuum interrupter is the small size vacuum pipe.
The utility model A.C. contactor changes encapsulating structure into, and volume is little, is convenient to drawer-type switch cabinet and selects for use; Because rectifying device, auxiliary contact and vacuum interrupter are encapsulated in base and the pedestal; Security performance is good; Long service life; Avoided accident collision to cause vacuum interrupter damage or foreign material to get into the phenomenon that its loose contact is caused in the vacuum interrupter moved end: in addition, the contact binding post of auxiliary contact is connected on the junction block through lead-in wire, makes things convenient for terminal block.
Appended drawings is the utility model structural representation.
Among the figure 1, base 2, coil 3, yoke 4, armature 5, junction block 6, rocking arm 7, reaction spring 8, auxiliary contact 9, bonnet 10, adjustment screw 11, pedestal 12, joint cover 13, flexible connection 14, vacuum interrupter 15, top cover
Embodiment is with reference to accompanying drawing; The utility model comprises that it comprises base 1, pedestal 11, rocking arm 6, calutron, vacuum interrupter 14, rectifying device and auxiliary contact 8; Rectifying device and auxiliary contact are encapsulated in the base 1 through bonnet 9; Vacuum interrupter 14 is encapsulated in the pedestal 11 through top cover 15, and the contact binding post of auxiliary contact 8 is connected on the junction block 5.
The utility model compact conformation; Cooperate said structure; Described vacuum interrupter 14 adopts the small size vacuum pipe, and is encapsulated in the pedestal 11 through top cover 15, has avoided accident collision to cause vacuum interrupter damage or foreign material to get into the phenomenon that loose contact is caused in the vacuum interrupter moved end; Described rectifying device and auxiliary contact 8 are encapsulated in the base 1 through bonnet 9, and the contact binding post of auxiliary contact 8 is connected on the junction block 5 through lead-in wire, can make things convenient for terminal block, prolongs its useful life; Base 1 is to be processed by the alloy aluminum with higher-strength, rocking arm 6, pedestal 11, top cover 15 be by have higher-strength, the insulation fire proofing is processed, bonnet 9 and auxiliary contact 8 shells are to process by having higher-strength, high are-tight property, insulation fire proofing.Through having increased contact pressure, reduce contact resistance, increase clearance between open contacts, improved make-break capacity, reduced the heating phenomenon of contact in closed base, make the work of contact more reliable.
