Description

The enclosed cell box

The utility model relates to a kind of enclosed cell box.

The development of dry cell, existing phase of history, this with electric power storing in cylindrical body so that use in case of necessity to be provided, really make the use of people to some electric equipment products, broken through the restriction of conventional power source, also bring greatest facility for people's life.

Therefore, the device of set battery just arises at the historic moment, and the placement of battery and harvesting, sometimes be to become one with this electrical appliance, as toy, palm shape broadcast receiver, flashlight or the like also have minimum part then to adopt separation, in addition, a kind of situation is still arranged, and promptly is the battery case of charging usefulness, that is to say usually in order to after putting nickel-cadmium cell, insert AC power again and, make the battery case of nickel-cadmium cell charging through the rectification step-down.

These battery accommodating apparatus, maximum characteristic promptly be its circuit of the overwhelming majority for series connection, trace it to its cause, be because of due to the voltage requirements, with the battery case of people known to usually, it be with two one group side by side, still, its circuit is series connection.

As shown in Figure 1, it is the battery case of using always, be that tool is born utmost point shell fragment 101 and anodal guide card 102 in a cassette holder 10, and drawing of each tool wiring, so battery can be placed in the aforesaid box chamber 103, simultaneously on the two side of box chamber 103 then each corresponding one extend some arc wings 104, wherein the curvature of this arc wing 104 is the arc footpaths corresponding to battery, to avoid deviating from of battery, but when it was applied to some electrical appliances, it had some defectives, for example, can't prevent effectively that liquid from contacting with battery, so cause battery drain or short circuit easily; Moreover the aforesaid arc wing can't prevent deviating from of battery really, because it has elasticity, so if coating oversize then battery is difficult for settling, too weak point can't prevent that then battery from coming off; Wiring easily causes short circuit, before dispatching from the factory in the battery case if with the attached battery of giving of box, when banking up, its wiring easily causes contact, and then forms short circuit in transportation for it, the electrical source consumption that makes battery totally.

The purpose of this utility model is to propose a kind of enclosed cell box of mainly being made up of cassette holder, lid and pole piece group, and it has, and overall package is firm, liquid is difficult for infiltrating characteristics such as battery case, thereby has solved the existing in prior technology problem.

The technical scheme that the utility model adopted is that it mainly is made of cassette holder, lid and pole piece group.Wherein cassette holder one side is established the box tenon of two subtends, intercalation for positive/negative plate, the box tenon of side and correspondence thereof is the intercalation that supplies pole piece every tenon in addition, the prominent box rib of establishing in box wall and antetheca top, and also prominent the establishing in lid and its corresponding position covered rib, make cassette holder and lid can be the sliding state that docks, and offer a cinclides on the antetheca, stretching out of supply lines: the setting of tool partition on the cassette holder, the one end extends upward one every rib, to prevent the contact of the two poles of the earth sheet: and the prominent hook tenon of establishing an inverted L shape on the antetheca, also open a button hole on the rear wall of its opposite end, then dashing forward and establish one section fin in the lid rib inboard of lid, supplies and lid rib double team box rib; Simultaneously corresponding to the then prominent clasp of establishing in button hole place, for engaging each other; Then establish the lid groove of an indent corresponding to hook tenon place, supply chimeric forming each other.Be provided with one in the cassette holder every post, lid then correspondence is established a lid hole, can borrow a screw to pass through again to cover Kong Bingyu every post locking person: wherein can also open an opening on the cassette holder, setting and expose for a switch feather key, and feather key is the then prominent sliding tenon of establishing of face in addition: and metal clips is chimeric with location lug, and the one end reverses, and can oppress shell fragment when moving to slide tenon, its sheet end is contacted, to form the conducting of circuit with pole piece; The prominent in addition prominent tenon of establishing prevents from excessively to pull electric wire in the cassette holder, make its and pole piece not reason excessively pull and cause coming off.

Lid can be opened a microscler slotted eye outside corresponding to pole piece, for the intercalation of an insulating trip, and make it to connect between the utmost point and pole piece between battery, to avoid the abnormal discharge of battery.Wherein, insulating trip is with bent made the becoming of macromolecule material thin slice, so that it can fit in lid.

Characteristics of the present utility model are:

(1) since the utility model be adopt closed, so liquid be difficult for to infiltrate battery case.

(2) firm and certain after the overall package, because tool box rib on the cassette holder, for the clamping of covering rib and fin, have button hole simultaneously for the engaging of clasp, and the hook tenon being chimeric with the lid groove, all signs an undertaking to attach together and puts in its four limit, so after the assembling, lid forms the firm aspect that combines with cassette holder.

(3) electric wire is difficult for coming off with pole piece, because electric wire is to walk around prominent tenon, so during with the electrical appliance assembling, when excessively pullling electric wire, it can be limited by aforesaid prominent tenon, makes the pad difficult drop-off of electric wire and pole piece, with the rate of reducing the number of rejects and seconds.

(4) have the setting of switch, borrow the pull switch feather key, can make the sheet end of its sliding tenon compressing shell fragment, it is contacted, the conducting of formation circuit with pole piece.Open circuit otherwise the shell fragment resilience is, so be installed on the electrical appliance, this electrical appliance need not to add separately puts switch.

(5) multiple insulation setting, as partition institute projection every rib, can prevent the contact of two pole pieces; And the setting of slotted eye can and be separated by between battery and pole piece the insulating trip intercalation, to prevent the abnormal discharge of battery.
