Description
Technical field
The present invention relates to capacitor manufacture field, specifically capacitor liquid injection device.
Background technology
Capacitor is electrical equipment conventional in circuit, after capacitor internal installation, the inside of capacitor will be carried out fluid injection, because if electrolyte runs into air and can discharge, first the air in capacitor is extracted out before fluid injection, note electrolyte again, theoretically capacitor perfect vacuum fluid injection again is best, but existing technology is unable to reach, electrolyte to inject until capacitor is full, owing to capacitor internal also has certain air before injection, cause capacitor internal pressure bigger, priming device leaves liquid injection port when, electrolyte can overflow, the method primarily now quickly liquid injection port covered by workman, electrolyte has certain corrosivity, the manual capping of workman has certain risk, and its service behaviour also can be affected with air contact.
Summary of the invention
The present invention is directed to prior art not enough, devise capacitor liquid injection device, this capacitor liquid injection device is prevented from electrolyte and overflows, and automatic sealing reduces workman's work risk.
In order to solve above-mentioned technical problem, the present invention is addressed by following technical proposals: capacitor liquid injection device, including the liquid injection hole on filling head and capacitor, described filling head top is provided with polygon cylinder, described filling head is circumferentially provided with the first external screw thread, described filling head is internal is liquid injecting pipeline, described liquid injecting pipeline is provided with the passage connected from both sides with described filling head outer wall, it is provided with female thread in described liquid injection hole, it is provided with plug in described liquid injection hole, the second external screw thread it is provided with outside described plug, described plug top is provided with polygonal hole, described polygonal hole coordinates with described polygon cylinder, described first external screw thread and described second external screw thread all with described screw-internal thread fit, liquid injection hole inside described capacitor is provided around convex edge, described convex edge sidewall is provided with the through hole coordinated with described passage.When this capacitor needs fluid injection, the polygonal hole inward turning that polygon cylinder on filling head is inserted on plug is turned to down, until described passage coordinates with described through hole and then carries out fluid injection, again filling head and plug are rotated together with upwards after fluid injection completes, fluid injection is i.e. completed until being extracted in polygonal hole by cylinder after the first external screw thread described female thread of disengaging, the electrolyte adopted in capacitor in this way is closed all the time, and it is automatically performed closure, worker safety improves, and fluid injection better quality.
In technique scheme, described polygon cylinder is hexagon, and described polygonal hole is hexagonal hole.
The present invention is compared with prior art, have the advantages that when this capacitor of the present invention needs fluid injection, the polygonal hole inward turning that polygon cylinder on filling head is inserted on plug is turned to down, until described passage coordinates with described through hole and then carries out fluid injection, again filling head and plug are rotated together with upwards after fluid injection completes, fluid injection is i.e. completed until being extracted in polygonal hole by cylinder after the first external screw thread described female thread of disengaging, the electrolyte adopted in capacitor in this way is closed all the time, and it is automatically performed closure, worker safety improves, and fluid injection better quality.

Detailed description of the invention
nullWith detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings: see Fig. 1 to Fig. 2，Capacitor liquid injection device，Including the liquid injection hole 2 on filling head 1 and capacitor，Described filling head 1 top is provided with polygon cylinder 11，Described filling head 1 is circumferentially provided with the first external screw thread 12，Described filling head 1 is internal is liquid injecting pipeline 13，Described liquid injecting pipeline 13 is provided with the passage 14 connected from both sides with described filling head 1 outer wall，It is provided with female thread 21 in described liquid injection hole 2，It is provided with plug 3 in described liquid injection hole 2，Described plug 3 is outside is provided with the second external screw thread 31，Described plug 3 top is provided with polygonal hole 32，Described polygonal hole 32 coordinates with described polygon cylinder 11，Described first external screw thread 12 and described second external screw thread 31 all coordinate with described female thread 21，Liquid injection hole 2 inside described capacitor is provided around convex edge 22，Described convex edge 22 sidewall is provided with the through hole 23 coordinated with described passage 14.In the present embodiment, described polygon cylinder 11 is hexagon, and described polygonal hole 32 is hexagonal hole.
When this capacitor needs fluid injection, polygonal hole 32 inward turning being inserted on plug 3 by polygon cylinder 11 on filling head turns to down, until described passage 14 coordinates with described through hole 23 and then carries out fluid injection, again filling head 1 and plug 3 are rotated together with upwards after fluid injection completes, after departing from described female thread 21 until the first external screw thread 12, polygon cylinder 11 is extracted in polygonal hole 32 and i.e. complete fluid injection, the electrolyte adopted in capacitor in this way is closed all the time, and it is automatically performed closure, worker safety improves, and fluid injection better quality.Being provided with stop part 15 on described filling head 1, in the present embodiment, stop part 15 realizes more than liquid injection hole 2 diameter with filling head 1 top external diameter, and the distance of described stop part 15 to described passage 14 is equal to the distance of described liquid injection hole 2 outer surface to described through hole 23.When this set makes filling head 1 turn to stop part 15 with the laminating of liquid injection hole 2 outer surface, described passage 14 just communicates with described through hole 23.
