Description
Technical field
The present invention relates to a kind of explosion-proof type capacitor, be related specifically to a kind of safety type capacitor with excess pressure explosion-protection equipment.
Background technology
The terminal of traditional capacitor is a round copper rod, and circle copper rod is connected by soldering with the lead-in wire of capacitor body, on the one hand, when fuse damages, causes internal pressure to increase, there will be the potential safety hazard that capacitor ensures because capacitor internal heats up; In addition on the one hand, because the welding difficulty of copper rod is very large, easy rosin joint, when capacitor work, that solder joint place often produces is overheated, the phenomenon of solder joint disconnection, makes capacitor earlier period damage, greatly reduces the reliability of capacitor, therefore technically have much room for improvement.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of highly reliable connection, explosion-proof fail safe capacitor are provided.
Technical scheme of the present invention is as follows:
A kind of explosion-proof type capacitor, comprises capacitor case, fuse, mandrel, and is positioned at the terminal of capacitor top connection power supply, it is characterized in that: described explosion-proof type capacitor also comprises explosion-proof block, and is arranged on the upper capacitor cover on explosion-proof block top; One end of described terminal be arranged on can with capacitor internal pressure move up and down on cover, one end is fixed through explosion-proof block by welding and lead-in wire and is electrically connected in addition; Described terminal lower portion is provided with screw thread.
When the damage of above-mentioned capacitor internal fuse and explosion-proof operating state, the upper cover that capacitor internal pressure increase promotes explosion-proof block top outwards moves, and drives terminal outwards to move, and makes terminal pull out explosion-proof block and disconnects with lead-in wire, forming explosion-proof fracture.
The above-mentioned depth of thread is 0.1 ~ 0.22mm.
The bottom of above-mentioned fuse is arranged and is fixed by lower positioning sleeve, and the top of core 3 is arranged and fixed by upper positioning sleeve.
Above-mentioned capacitor case inside is provided with insulating paper, is filled with insulation filling agent between insulating paper inside and fuse.
Beneficial effect of the present invention: one is have simple, reliable explosion prevention function, and capacitor adopts upper cover pressure explosion-proof structure, when capacitor internal fuse damages, upper cover motion is promoted by internal pressure, drive terminal to be separated with the lead-in wire of fuse, thus disconnect with power supply, play a protective role; Two be solder joint connect reliably do not affect again explosion-proof, one end of capacitor terminal and copper rod is processed screw thread, significantly reduce the difficulty of itself and wire bonds, improve the reliability of solder joint, stop rosin joint phenomenon, significantly improve conveyance capacity and the reliability of capacitor, the depth of thread is 0.1 ~ 0.22mm simultaneously, effectively prevents weld strength from causing too greatly explosion-proof performance to decline.

Embodiment
For being illustrated more clearly in content of the present utility model, be further described below in conjunction with the drawings and specific embodiments.
As depicted in figs. 1 and 2, a kind of explosion-proof type capacitor, comprises capacitor case 6, fuse 3, mandrel 2, and is positioned at the terminal 11 of capacitor top connection power supply, described explosion-proof type capacitor also comprises explosion-proof block 9, and is arranged on the upper capacitor cover 12 on explosion-proof block 9 top; One end of described terminal 11 is arranged on the upper cover 12 that can move up and down with capacitor internal pressure, and one end is fixed through explosion-proof block 9 by welding and lead-in wire 8 and is electrically connected in addition; Described terminal 11 bottom is provided with screw thread 13.
When the damage of capacitor internal fuse and explosion-proof operating state, capacitor internal pressure increase, by upper capacitor cover 12 jack-up, namely the upper cover 12 promoting explosion-proof block 9 top outwards moves, drive terminal 11 outwards to move, make terminal 11 pull out explosion-proof block 9 and disconnect with lead-in wire 8, forming explosion-proof fracture 10.Connection between capacitor terminal 11 and fuse 3 can be disconnected by the terminal 11 of explosion-proof block 9, special construction, thus capacitor body 3 and power supply are disconnected, play a protective role.
By machining, capacitor terminal 11 i.e. copper rod is processed screw thread 13, significantly reduce the difficulty of welding, improve the reliability of solder joint 14, stop rosin joint phenomenon, significantly improve conveyance capacity and the reliability of capacitor.
Screw thread 13 degree of depth is 0.1 ~ 0.22mm.Because capacitor is upper cover pressure explosion-proof structure, the degree of depth of screw thread 13 can not be too dark, otherwise weld strength between the lead-in wire 8 of terminal 11 and fuse 3 is too large, affects product explosion-proof.The depth of thread is set to 0.1 ~ 0.22mm scope, has both met the requirement that Product jointing reliably connects, and does not affect the explosion-proof performance of product simultaneously.
The bottom of fuse 3 arranges and passes through lower positioning sleeve 1 and fixes, and the top of fuse 3 arranges and passes through upper positioning sleeve 7 and fixes.
Capacitor case 6 inside is provided with insulating paper 4, is filled with insulation filling agent 5 between insulating paper 4 inside and fuse 3.
Above-described embodiment can not think the restriction to the utility model protection range, the improvement that those skilled in the art make based on technical solutions of the utility model or means, all should fall into the protection range of the utility model claim.
