Abstract
The utility model discloses a connection device of a high voltage nickel-metal hydride battery which includes a battery housing; a post head is inserted on the battery housing; the lower section of the post head is provided with a conical curved surface and the upper section of the post head is provided with a screw thread; a seal ring and an insulating cushion are sleeved and arranged on the post head; the inner side of the seal ring is contacted with the conical curved surface and the outer side is matched with the battery housing. The insulating cushion is arranged at the upper end of the battery housing and a locking nut is spirally connected with the post head; a ventilating hole is arranged in the post head. The utility model processes the part in the battery housing into the conical curved surface and then adopts an inner ring to be matched with the conical curved surface of the post head; the outer side is provided with the seal ring matched with the inner wall of the battery housing. When the battery housing is added with high voltage hydrogen, the post head drives the seal ring to move upwards under the pressure to lead the inner side and the outer side of the seal ring to be tightly stuck on the conical curved surface of the post head and the inner side of the battery housing; thereby playing the role of sealing.
Description
Technical field
The utility model relates to a kind of high-voltage nickel-hydrogen battery, particularly a kind of termination of high-voltage nickel-hydrogen battery.
Background technology
High-voltage nickel-hydrogen battery is by the nickel electrode of ickel-cadmium cell and electric grade of chemical power source system that combines and form of catalysis hydrogen of fuel cell, and its distinguishing feature is that the life-span is long, shows on the aircraft such as extensively being applied to aviation.The durability of high-voltage nickel-hydrogen battery is subjected to the influence of battery sealing-performance; Wherein the hydrogen in the pressure vessel is as negative electrode active material, if hydrogen leak, the electrical property of battery then can obviously reduce.For preventing the gas leakage of binding post position, the connection of joint pin all is to adopt riveted way to be tightly connected at present, and this mode of being tightly connected has the following disadvantages, and the airtight success rate of the first riveted joint mode is low, and sealing effectiveness is bad; Not quick detachable after second riveted joint, the joint pin waste is more serious; The 3rd binding post purposes is single, can only use as battery plus-negative plate.
Summary of the invention:
The technical problems to be solved in the utility model is: a kind of good airproof performance, simple in structure is provided, and binding post also can be used as the termination of the high-voltage nickel-hydrogen battery of gas filler, battery plus-negative plate simultaneously, to overcome the deficiencies in the prior art.
The technical scheme that the utility model is taked is: it comprises battery container 1, on battery container 1, be inserted with binding post 2, hypomere at binding post 2 is provided with conical surface 3, is provided with screw thread 4 at the epimere of binding post 2, and is socketed with a sealing ring 5 and insulation cushion 6 on binding post 2; The inboard of sealing ring 5 contacts with conical surface 3, matches with battery container 1 in the outside, and insulation cushion 6 is positioned at battery container 1 upper end, and also is connected with locking nut 7 on binding post 2, is provided with air vent hole 8 in binding post 2.
The face that battery container 1 matches with sealing ring 5 is a taper seat.
And between locking nut 7 and insulation cushion 6, also be provided with packing ring 9.
The quantity that is connected the locking nut 7 on the binding post 2 is two.
On air vent hole 8, be provided with unidirectional valve.
Binding post 2 is a stainless steel line post.
Compared with prior art, the utility model is processed into conical curved surface with the part of binding post in battery container, adopts an inner ring to cooperate the sealing ring that the outside cooperates with the battery container inwall with the conical curved surface of binding post again; Like this before not charging into hydrogen in the battery container, binding post is tight not enough with engaging of battery container, there is the slit, when from the air vent hole of binding post after the sealed cell housing adds high pressure hydrogen, the internal pressure of battery container will be much larger than external pressure, and under the effect of pressure, binding post drives sealing ring and moves upward, make the inside and outside both sides of sealing ring all tightly be attached on the conical curved surface of binding post and the battery case inboard, thereby reach sealing function.Be socketed in the insulation cushion on the joint pin and binding post directly do not contacted with battery container and have insulating effect at joint pin and sealing ring between the battery case; Be screwed in two locking nuts on the binding post, have relaxation effect.Simultaneously through evidence, the utility model not only has advantages such as good conductivity, good airproof performance, resistance to pressure are good, and can also be as the usefulness of gas filler.Therefore the utlity model has the excellent popularization value and use value.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structure schematic diagram of binding post 2;
Fig. 3 is the structure schematic diagram of sealing ring 5.
Embodiment
Embodiment of the present utility model: structure of the present utility model as depicted in figs. 1 and 2, binding post 2 adopts stainless steel to be processed into, the hypomere of binding post 2 is processed with conical surface 3, the epimere of binding post 2 is processed with screw thread 4, and on binding post 2, also be drilled with air vent hole 8, in air vent hole 8, be provided with unidirectional valve.
When making high-voltage nickel-hydrogen battery, before battery container 1 does not weld, planform sealing ring 5 as shown in Figure 3 is socketed on the binding post 2, sealing ring 5 adopts the plastic monoblock compacting to form, can match with the conical surface 3 of binding post 2 in the inboard that is socketed in the sealing ring 5 on the binding post 2, the outside can cooperate with the open section in the battery container 1; The thread segment of binding post 2 upper end from battery container 1 is passed, successively insulation cushion 6, packing ring 9 are socketed on the screw thread 4 of binding post 2 then, screw in locking nut 7 then, for preventing that binding post 2 from use getting loose, the quantity of locking nut 7 is preferably two, after locking nut 7 screwed, seal welding battery container 1 got final product.
When the air vent hole 8 from binding post 2 adds high pressure hydrogen in the battery container 1 of sealing after, the air pressure inside of battery container 1 will be much larger than outside atmospheric pressure, under the effect of pressure, binding post 2 drives sealing ring 5 and moves upward, make the inside and outside both sides of sealing ring 5 all tightly be attached on the conical curved surface 3 of binding post 2 and the inboard of battery case 1, thereby reach sealing function.Be socketed in the insulation cushion 6 on the joint pin 2 and binding post 2 directly do not contacted with battery container 1 and have good insulating effect at joint pin 2 and sealing ring 5 between the battery case 1.
