Embodiment
The embodiment of a kind of flexible-packed battery group of the utility model, as Figure 1-3: comprise six mounted on top battery 1 together, each battery 1 is in parallel by connector 4.Connector 4 is interval with the slot that the lug for battery inserts, in a described slot, is fitted with a corresponding lug.Each battery 1 all has the square lug in two, left and right, and one is anode ear 3, and another is negative electrode lug 2.Anode ear 3, the negative electrode lug 2 of each battery are connected in parallel respectively by corresponding connector, and anode ear in parallel is identical with the structure of the connector of negative electrode lug in parallel.Below the structure of the connector of positive pole ear in parallel is described.
The cross section of connector 4 is waveform, and connector 4 is provided with the slot identical with anode ear quantity, and slot is U-type groove 44.Each U-type groove 44 along the vertical direction interval is arranged in the side of the close anode ear 3 of connector, and U-type groove 44 extends in left-right direction.The spacing of the above-below direction of each slot on connector 4 equals the spacing of the above-below direction of the anode ear of each battery.For the ease of the insertion of anode ear 3, prevent the distortion causing anode ear in assembling process, the notch place of U-type groove 44 is provided with guide frame, and the notch place of U-type groove 44 forms chamfering structure 45, and its cross section is splayed.Bottom land and the anode ear 3 of U-type groove 44 are welded and fixed by the mode of laser welding.
In order to alleviate the quality of connector 4, formed between two adjacent U-type groove 44 opening and U-type groove 44 notch towards the opposite, the inner fovea part 43 that caves in anode ear side.The side relative with slot on connector 4 is provided with the observation panel 41 of the distance for observing anode ear and slot bottom land, and observation panel 41 is communicated with the bottom land of corresponding U-type groove 44.The observation panel of the dorsal part of each U-type groove 44 has two and lays respectively at two ends, left and right place.At anode ear 3 with the process of connector 4 plug-in mounting, the distance of the bottom land of anode ear and U-type groove can be observed by observation panel 41, judge whether anode ear inserts and put in place.If the distance of the bottom land of anode ear and U-type groove exceeds the fusion penetration of laser welding, the distance between connector 4 and anode ear 3 is adjusted, to ensure the reliability of welding.After welding, by observation panel 41 also to check connector 4 and the depth of weld of anode ear 3, can the soldering reliability after welding be assessed.Further, be provided with laser welding identifying hole 42 in the bottom of the inner fovea part of connector, by the size in seam recognition hole 42, the bonding power of laser adjusted.Different suitable bonding powers is adopted to the connector of different-thickness, material, avoids the heat that the excessive generation of laser power is larger, cause waste, the too small welding caused of laser power also can be avoided unreliable simultaneously.Select suitable laser bonding power, reduce welding cost, improve welding efficiency.
The side relative with slot on connector 4 is provided with gathering line terminals 5, the voltage of battery pack, electric current, temperature parameter can be passed to corresponding data acquisition unit by gathering line terminals 5, for checking, analyzing.
In the present embodiment, in order to be beneficial to laser welding, positive and negative lug, the gathering line terminals of connector, battery all adopt identical metal material.
In other embodiments, the guide frame at U-type groove mouth place, also can adopt and form fillet at U-type groove mouth place.
In the present embodiment, U-type groove is through in left-right direction, and in other embodiments, U-type groove also can not be through.In other embodiments, slot also can adopt V-type groove, arc-shaped slot.
In other embodiments, when slot is U-type groove, applies active force by outside and make U-type groove clamp corresponding lug, also can realize conduction and connect.
A kind of flexible-packed battery group of the utility model syndeton, this syndeton comprises lug and the connector of battery, and wherein the structure of connector is identical with the structure of the connector in above-mentioned flexible-packed battery group embodiment, and embodiment repeats no more.
