Like this, the storage assembly that connects a plurality of storage batterys is applicable to for example battery of portable electronic equipment.Portable electric appts for example has notebook computer, mobile phone, PDA (personal digital assistant), portable music media player etc.

In storage assembly of the present invention, above-mentioned storage battery has surrounding wall portion, this surrounding wall portion two storage batterys in the relative mode of mutual above-mentioned terminal near the time, surround above-mentioned terminal the side, mark off the connection space that comprises above-mentioned terminal, when utilizing above-mentioned connector to carry out the electrical connection fixed to one another of above-mentioned terminal, above-mentioned connector is preferably in the connection space of sealing.By such structure, connected terminal is subjected to the protection of surrounding wall portion each other.For example, can utilize surrounding wall portion liquid thickly to divide connection space, can protect terminal effectively.Its result can prevent foreign matter attached on the terminal, and the action of electrical storage device is stable, can improve reliability.

In addition, surrounding wall portion can be arranged on interconnective two sides' the storage battery, also can only be arranged on either party storage battery.

And, in storage assembly of the present invention, also can use the closure assembly of connecting portion between above-mentioned terminal.In this case, the convex cover parts of closure assembly and recessed cap assembly are installed on the terminal under respectively by the state of either party clamping of the male connector parts of a side of the terminal of above-mentioned storage battery and above-mentioned connector or female connector parts.

Electrical storage device of the present invention has a plurality of above-mentioned storage assemblies.According to such structure, can form the large-scale electrical storage device (ultra-capacitor) that for example has hundreds of storage batterys, the power supply that can be used as electric automobile for example etc. uses.In this case, hundreds of storage batterys must be connected, but, therefore packaging efficiency can be improved significantly owing to can connect by the quick-snap of connector.

In addition, electrical storage device for example utilizes bus or bus bar plate to be electrically connected a plurality of storage assemblies and constitutes.

On such storage assembly and bus or bus bar plate, can suitably use the syndeton of storage battery of the present invention.Especially, in following syndeton, promptly, contacting by the mutual end face that makes male connector parts and female connector parts towards the axis direction of inner ring portion, simultaneously, the inner peripheral surface of the outer peripheral face of the outer ring portion of mutual crimping male connector parts and the outer ring portion of female connector parts, carry out in the connection structure connecting of male connector parts and female connector parts with this, owing between the end face that the inner ring portion of male connector parts and female connector parts is in contact with one another, form current path, and between the inner peripheral surface of the outer ring portion of the outer peripheral face of the outer ring of male connector parts portion and female connector parts, form current path, therefore, on male connector parts and female connector parts, form outer ring portion and two current paths of inner ring portion.Therefore, area can be increased, big electric current can be passed through by electric current.

At this, the outer ring portion of male connector parts and female connector parts can be made of plastic deformation parts or elastomeric element.Under the situation of using the plastic deformation parts, the inner peripheral surface of the outer peripheral face of outer ring portion that can mutual fastening male connector parts and the outer ring portion of female connector parts.On the other hand, under the situation of using elastomeric element, the inner peripheral surface of the outer peripheral face of the outer ring portion of male connector parts and the outer ring portion of female connector parts elasticity is mutually pushed.Elastomeric element is because the specific plastic deformation component has more durability, and is therefore more suitable.

In above-mentioned mode,, can use various structures in order to reduce the connection resistance between male connector parts and the female connector parts.For example, the outer peripheral face of the outer ring portion of male connector parts can have along with leaving the female connector component side at the wide diameter portion of radial direction hole enlargement.In this case, under male connector parts and state that the female connector parts are connected, the inner peripheral surface of the wide diameter portion of the outer ring portion of male connector parts and the outer ring portion of female connector parts can flexibly be pushed mutually.And the inner peripheral surface of the outer ring portion of female connector parts can have along with leaving the male connector component side in the tube reducing portion of radial direction tube reducing.In this case, under male connector parts and state that the female connector parts are connected, the reducing diameter part of the outer peripheral face of the outer ring portion of male connector parts and the outer ring portion of female connector parts can flexibly be pushed mutually.

For above-mentioned male connector parts and female connector parts are fixed on the body of storage battery, can utilize various structures.For example, can on the inner peripheral surface of the inner ring portion of male connector parts and female connector parts, form the threaded portion, in the outer peripheral edges portion of the outer ring portion of male connector parts and female connector parts, form a plurality of towards the outstanding calvus in the radial direction outside.In this case, calvus can be used as the snap portions of the regulation instrument that uses when being threaded the threaded portion.In such mode,, therefore, when the terminal with male connector parts or female connector parts and storage battery screws togather fixedly, can easily carry out it and fix because calvus is used as the snap portions of regulation instrument.

Calvus can form in every way.For example, in order to discern male connector parts and female connector parts easily, can make the quantity of calvus different mutually.And, the calvus that adjoins each other with terminal of at least one side in the calvus of male connector parts and female connector parts can be linked by linking part.In such a way, can improve the intensity of calvus by linking part.And, under the situation that the calvus that adjoins each other of connector component with either party links by linking part, because the male connector parts are different with the shape of the calvus of female connector parts, therefore, can discern male connector parts and female connector parts easily.

The calvus of male connector parts and female connector parts equally spaced can be formed along circumferencial direction, the quantity that can make the calvus of male connector parts and female connector parts is the positive several times of the number of teeth of regulation instrument.In such mode,, can use general instrument male connector parts and female connector parts being screwed togather when being fixed on the terminal.

For above-mentioned instrument is engaged with calvus easily, for example the calvus of male connector parts and/or female connector parts can have along with towards the outside of radial direction with shape near the mode bending of the other side's side-connector parts.In such a way, can increase line or the area that instrument engages with the calvus of male connector parts and/or female connector parts.

In order easily a plurality of storage batterys that connected male connector parts and female connector parts to be carried out the voltage inspection, can utilize various structures.For example, can have packing ring, this packing ring has the surrounding wall portion that forms discoideus base portion, forms along its outer peripheral edges portion and has from this surrounding wall portion upper end to the outstanding edge portion in the radial direction outside.In this case, packing ring can be fixed between the terminal of at least one side of male connector parts and female connector parts and storage battery.In in such a way can a plurality of storage batterys after connection,, conductor carries out voltage detecting by being present between the edge portion of surrounding wall portion upper end of relative mutually packing ring.

As above-mentioned connector also applicable to the bus that uses in order to connect a plurality of storage batterys.Bus of the present invention has bus bar plate and above-mentioned connector, and the male connector parts of above-mentioned connector are fixed on an end of above-mentioned bus bar plate, the female connector parts is fixed on the other end of above-mentioned bus bar plate.In this case, preferably male connector parts and female connector parts are fixed on the bus bar plate by welding.And above-mentioned calvus can be suitable as welding surplus (welding generation) and use.

Utilize bus of the present invention the female connector parts of one side's storage battery can be connected on the male connector parts of bus bar plate one end, the female connector parts of the opposing party's storage battery can be connected on the male connector parts of bus bar plate the other end.

As mentioned above, as the mother metal of connector the high aluminium terminal of low copper of ionization trend and ionization trend is contacted under the situation about using, aluminium terminal is because the galvano-cautery effect has the problem of thickness reduction.

Therefore, preferably will be than the ionization tendency of mother metal (copper) electrodeposited coating of big metal Ni be formed on the surface of mother metal.Because Ni is than the ionization tendency height of mother metal (copper), therefore under the situation of difference in Electrode Potential relatively, Ni-aluminum ratio copper-aluminium is little, therefore can prevent the galvano-cautery of the aluminium terminal that contacts.

But the Ni electrodeposited coating is hard, conduction is poor.Therefore, the rough surface (concavo-convex) of filling and leading up connector component is very difficult, and the male connector parts during quick-snap and the adaptation of female connector parts are poor, and conduction is poor, and be corresponding, with the contact resistance increase of terminal.

Such problem can solve in the following manner,, forms the good Cu-Sn electrodeposited coating of conduction on the Ni electrodeposited coating that is, remedies the deficiency of the conduction of Ni electrodeposited coating.And, because the Cu-Sn electrodeposited coating is softer, therefore, male connector parts and female connector parts are when carrying out quick-snap, can fill and lead up the rough surface (concavo-convex) of connector component, strengthen the fitting tightly property of male connector parts and female connector parts, and the sliding during quick-snap might as well.

And, as mentioned above,, therefore need to form thin electrodeposited coating because Ni electrodeposited coating conduction is poor.On the other hand, the Cu-Sn electrodeposited coating is difficult to form thick electrodeposited coating, and thickness is restricted in common electroplating processes.

Therefore, increase the whole thickness of electrodeposited coating, further improve under the situation of electrocorrosion-resisting, be preferably in the top Sn electrodeposited coating that forms again of above-mentioned Cu-Sn electrodeposited coating.The deficiency that Sn electrodeposited coating conduction is good, can remedy the conduction of Ni electrodeposited coating simultaneously, can form thick electrodeposited coating.And, the corrosion resistance of Sn electrodeposited coating is very strong, be suitable as very much superficial layer, and, because electrodeposited coating is soft, therefore, male connector parts and female connector parts are when carrying out quick-snap, can fill and lead up the rough surface (concavo-convex) of connector component, strengthen the fitting tightly property of male connector parts and female connector parts.But because its softness, the trend of the sliding when therefore easy destruction quick-snap is arranged.In addition, though it is very difficult to form the Cu-Sn electrodeposited coating on the Sn electrodeposited coating, can form the Sn electrodeposited coating at the Cu-Sn electrodeposited coating.And, omitting the Cu-Sn electrodeposited coating, forming under the situation of two-layer Sn electrodeposited coating, concavo-convex increase, male connector parts and the female connector parts on surface are difficult to quick-snap.

Can learn in desired characteristic of each electrodeposited coating from the above description and the feature that the Ni thickness of plating layer is about 0.1～15 μ m, the Cu-Sn thickness of plating layer is about 0.1～10 μ m, the Sn thickness of plating layer is to be appropriate about 0～25 μ m.

And the formation of each electrodeposited coating uses well-known method to get final product, and is generally undertaken by a series of processing such as ungrease treatment, washing processing, acid activity processing, electroplating processes, (preventing the variable color processing), washing (hot water wash) processing, dried.

Form the Ni electrodeposited coating and use as the sulfate of the ionogenic nickelous sulfate of Ni etc. and the Ni electroplate liquid that contains the chloride, boric acid etc. of nickel chloride, ammonium chloride etc., the concentration of the sulfate of nickelous sulfate etc. is generally enough about 150～500g/L.

And form Cu-Sn electrodeposited coating and Sn electrodeposited coating can use cyanogen-stannic acid liquid of always using, cyanogen-pyrophosphoric acid liquid, pyrophosphoric acid liquid (with reference to the spy open the 2004-35980 communique, the spy opens 10-102278 communique, No. 3455712 communique of patent) etc.As copper ion source, the water-soluble mantoquita that copper sulphate, copper nitrate, copper carbonate, Loprazolam copper, sulfamic acid copper, 2-hydroxyethanesulfonic acid copper, 2-hydroxypropanesulfonic acid copper, copper chloride, cupric pyrophosphate etc. are for example arranged, and, as stannous ion source, water-soluble pink salts such as stannous pyrophosphate, stannous chloride, stannous sulfate, stannous acetate, the inferior tin of sulfamic acid, the inferior tin of gluconic acid, the inferior tin of winestone, stannous oxide, sodium stannate, potassium stannate, the inferior tin of Loprazolam, the inferior tin of 2-ethylenehydrinsulfonic acid, the inferior tin of 2-hydroxypropanesulfonic acid, boron stannous fluoride are for example arranged.The mediation amount of water-soluble mantoquita is that copper is the scope about 0.05～40g/L, and the mediation amount of water-soluble pink salt is that tin is the scope about 1～60g/L.

And, above-mentioned electroplate liquid is with existing identical, and the additive that also can suitably select glazing agent, interfacial agent, the stress of ammonia derivative or aldehyde derivatives etc. to reduce agent, conductivity assistant, antioxidant, defoamer, pH buffer etc. as required adds.

In addition, connector of the present invention except plastic cap assembly or packing ring, preferably carries out of the present invention electroplating processes to metal cap assembly or packing ring by under cap assembly or packing ring and the situation that terminal is connected.
