Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, to the technical side in the utility model embodimentCase is clearly and completely described, and obviously, described embodiment is only that the utility model part is realExecute example, instead of whole embodiment. Based on the embodiment in the utility model, ordinary skill peopleMember, not making the every other embodiment obtaining under creative work prerequisite, belongs to the utility modelThe scope of protection.
As shown in Fig. 1～4, the battery pack of the present embodiment comprises: housing 1 and be positioned at some strings of housing 1The battery 2 of connection, connects by fuse link 4 between at least adjacent two batteries 2. Fuse link 4 middle parts are formed withAt least one projection 41, on housing 1, the position of corresponding fuse link 4 is provided with opening 11, and establish opening 11 topsHave the lid 3 removably connecting with housing 1, lid 3, for covering opening 11, is protected fuse link 4 and shellStructure in body 1. The first brace 6, the second is installed on the electrode of the first battery of adjacent two batteries 2The second brace 7 is installed on the electrode of battery, and the first end of fuse link 4 and the first brace 6 detachably connectConnect, the second end and the second brace 8 removably connect.
On the housing 1 of the battery pack of the present embodiment, the position of corresponding fuse link 4 is provided with opening 11, and fuse link4 two ends respectively with the detachable connection in the two poles of the earth of adjacent two batteries, in the time that fuse link 4 is blown, openLid 3, pulls down the fuse link blowing 4 by opening 11 from the two poles of the earth of adjacent two batteries, what renew is moltenPart, has reached the beneficial effect of being convenient to maintenance.
In the present embodiment, fuse link 4 and the first brace 6 and the second brace 7 be detachable be connected passableFor: on the first brace 6 and the second brace 7, be respectively equipped with slot, the first end of fuse link 4 and secondEnd inserts respectively the slot of the first brace 6 and the slot of the second brace 7.
As shown in Figure 1, in the present embodiment, fuse link 4 and the first brace 6 and the second brace 7 are removableThe formula of unloading connects: the first brace 6 is provided with slot 61, the second braces tops and is provided with button and opensClose 5, key switch 5 is fixed on lid 3, and the first end of fuse link 4 inserts described slot 61, the secondEnd is between key switch 5 and the second brace 7. After UNICOM's electrical appliance, the switch 5 that pushes button, buttonSwitch 5 is pressed on the second end of fuse link 4 on the second brace 7, whole circuit turn-on, then press byKey switch 5, key switch 5 is upspring, and the second end of fuse link 4 does not contact the second brace 7, whole circuitDisconnect, this structure is convenient to the control to battery pack break-make. Because key switch 5 is fixed on lid 3,In the time that fuse link 4 blows, key switch 5 takes off with lid 3, is also convenient for changing fuse link 4.
In the present embodiment, the middle part of the projection 41 of fuse link 4 has been symmetrically formed two gap 42. Because according toPoint discharge effect, when being conducive to battery pack in short circuit or transshipping with the projection 41 of two symmetrical gap 42Fuse link 4 is concentrated thermal stress compared with narrow part and is fused. And two gap 42 form technique and also compareSimply.
The two sides of the projection 41 of fuse link 4 at least one side on be formed with heat-resistant insulation material layer. This is heat-resisting absolutelyThe Main Function of edge material layer is, can ensure can not have influence on during by fusing at fuse link 4 battery pack withAnd other annex, thereby can more effectively protect battery pack, can be subject to significantly its service lifeImpact. Meanwhile, the heat producing when this heat-resistant insulation material layer can also avoid this battery pack normally to work damagesHinder battery or other article. Generally, this heat-resistant insulation material layer can be selected common exotic material,For example: iron lotus or high-temperature insulation adhesive plaster etc. And the heat-resistant insulation material layer of upper and lower surface can be both sameThe heat-resistant insulation material layer that the material of sample is made can be respectively also the high temperature insulation material that different materials is madeThe bed of material.
Lid 3 is made for heat-resistant insulation material, in case fuse link 4 burns out lid while fusing. Fuse link 4 canTo become by nickel or copper, or this fuse link 4 is nickel plating steel disc. Concrete, fuse link 4 is generally by thinNickel sheet or copper sheet directly cutting form, and manufacture craft is simple, and therefore the battery pack in the present embodiment is not only manufacturedConvenient, with low cost, and its use is also very convenient.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model,All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., allWithin should being included in protection domain of the present utility model.
