Abstract
The utility model discloses an improvement structure of an alternating-current vacuum contactor wiring terminal. An alternating-current vacuum contactor is composed of an insulation frame, a vacuum arc extinguishing device, an electromagnetic system, a transmission mechanism, an auxiliary switch system, a plurality of wiring terminals and a base. The wiring terminals are connected with the vacuum arc extinguishing device, the electromagnetic system, the transmission mechanism and the auxiliary switch system; and the plurality of the wiring terminals are uniformly fixed onto the upper surface of one side of the base to prevent dust, particles and even other metal parts from normally falling in when the improvement structure is in use, and to avoid failures of electric short circuit, mechanical jamming and the like.
Description
Technical field
The utility model relates to a kind of vacuum contactor, particularly a kind of AC vacuum contactor terminals structure-improved.
Background technology
The same with common A.C. contactor, vacuum contactor also is a kind of mechanical switch, promptly realizes the connection and the disjunction of circuit by the mechanical movement of contact.Different is, the contact of vacuum contactor is sealed in the vacuum and (is called vacuum interrupter or vacuum switch tube), utilize the vacuum medium of excellent performance to make insulation isolation and arc extinguishing means, thereby have advantages such as operating voltage is higher, the arcing time short, the contact electrical wear is few, contact surface non-oxidation.Present widely used have CKJ5 series, CKJ8 series, CKG3 series, CKG4 series etc.; The operating mechanism of vacuum contactor adopts electromagnet mostly, and by contact motion in the motion drive switching tube of armature, electromagnet is controlled by the power supply of low-voltage, low capacity; Vacuum contactor has some auxiliary contact mostly, and auxiliary contact and main contact are driven by same mechanism, is used to control system that signal is provided; The present following problem of widely used each serial vacuum contactor ubiquity: control and boost line insert inconvenient; not protection of vacuum switch tube and electromagnetic system simultaneously; dust during use in the surrounding environment, particle even other metal parts regular meeting fall into, and cause faults such as electric short circuit, mechanical jam.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of AC vacuum contactor terminals structure-improved, and this improvement AC vacuum contactor structure can conveniently be controlled and boost line inserts, and closed interior system simultaneously, increases fail safe.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of AC vacuum contactor terminals structure-improved, its described AC vacuum contactor is made of Insulating frame, vacuum arc-extinguishing device, electromagnetic system, transmission mechanism, auxiliary switch system, some binding posts and base, described binding post connects vacuum arc-extinguishing device, electromagnetic system, transmission mechanism and auxiliary switch system, and described some binding post unifications are fixed at a side upper surface of base.
As further improvement of the utility model, described some binding post alignment are arranged and are formed terminal board, are convenient to terminal block.
As further improvement of the utility model, described Insulating frame is structure as a whole, described Insulating frame top is provided with the groove that at least one opening makes progress, for ccontaining vacuum arc-extinguishing device and transmission mechanism, the bottom is provided with first groove that Open Side Down, for ccontaining electromagnetic system, the auxiliary switch system, be provided with one in the middle of the described Insulating frame and laterally place the dividing plate that is used for the spacing convave trough and first groove, also be provided with a upper cover plate, described upper cover plate is removably fixed in the opening surface of the top groove of Insulating frame, and the opening surface of described Insulating frame bottom first groove is removably fixed on the base.
As further improvement of the utility model, described vacuum arc-extinguishing device and transmission mechanism are located at upper cover plate and Insulating frame and are connected in the closed pockets that the back forms; Described electromagnetic system and auxiliary switch system are located at Insulating frame and base and are connected in formed sealing first groove in back; whole system is in most of enclosed construction; prevent that dust, particle even other metal parts regular meeting in the surrounding environment from falling into, and causes faults such as electric short circuit, mechanical jam.
The beneficial effects of the utility model are: described some binding post unifications are fixed at a side upper surface of base, described some binding post alignment are arranged and are formed terminal board, made things convenient for the access of control and boost line, described vacuum arc-extinguishing device and part transmission mechanism are located at upper cover plate and Insulating frame and are connected in the closed pockets that the back forms; Described electromagnetic system and auxiliary switch system are located at Insulating frame and base and are connected in formed sealing first groove in back; make and prevent that dust, particle even other metal parts regular meeting in the surrounding environment from falling into, and avoids causing faults such as electric short circuit, mechanical jam when using.
