[80]
Hereinafter, it will be described with respect to the lead cartridge 200, according to one embodiment of the present invention.
[81]
Figure 7 is the lead cartridge front according to one embodiment of the invention, Fig. 8 is a back view of a lead cartridge according to an embodiment of the present invention, Figure 9 is a lead cartridge according to an embodiment of the present invention and a view schematically illustrating a state sensing bus bar is attached, Figure 10 is' a cross-sectional view of the line, 11 is a D-D of Figure 3, C-C of Figure 3 a cross-section of the line.
[82]
Referring further to FIG. 7 to 11, the lead cartridge 200 can receive a portion of the electrode leads 110 and 130 on the inner side such that only the electrode leads 110 and 130 to contact each other electrically connected. In addition, the lead cartridge 200 can be separated from the inter-electrode lead (110, 130), the electrode leads 110 and 130 protrude to the outside and the remaining portion of the protrusion.
[83]
To this end, the lead cartridge 200 may be separately provided to each electrode lead (110, 130) to contact each other, it can be stacked in a stacked vertical direction (± Y direction) of the battery cells 100.
[84]
On the other hand, the lead cartridge 200 is a second electrode lead (130 of the first lead cartridge 210 and the electrode leads 110 and 130 for receiving and supporting a first electrode lead (110) of the electrode leads 110 and 130 ) a may be configured to receive and support the second lead cartridge 230.
[85]
First with 1 lead cartridge 210 and the second lead cartridge 230, so the configuration and the role similar to describe first the first lead cartridge 210, and the second lead cartridge 230 includes a first lead cartridges 210 It will be described with the focus on the differences.
[86]
First lead cartridge 210 may have a two post portions (211, 212), the partition wall 213, a first spacing 214, second spacing 215 and the support 216.
[87]
Two post portions 211 and 212 will serve to support the structure of the first lead cartridge 210 described above in each position on one outer side and the other end outside of the first electrode lead 210 is formed from a rectangular solid form, can.
[88]
More specifically, the two post parts (211, 212) between a first electrode lead 210 is located, the first electrode partition wall 213 formed of a plate shape along the length of the lead 210, the first of spaced portion 214, it is possible to support two spaced-apart portions 215 and the support portion 216 at one end and the other end outside the outside, respectively.
[89]
In other words, the first lead main configuration of the partition wall 213, a first spacing 214, second spacing 215 and the support 216 is located at each end outside and the other end outside of the cartridge (210) It is supported by two post portions (211, 212) which can house and support a first electrode lead (210).
[90]
On the other hand, two post portions 211 and 212 can be bonded to the first lead cartridge 210, located adjacent to the top and bottom, and first lead cartridge 210 and the second lead cartridge as located adjacent to the left and right (230 ) may be combined. This will be so described below in detail for the role of binding the lead cartridge between the two post parts (211, 212).
[91]
The partition wall 213 has two post portions 211 and 212 in the vertical direction is formed of a plate type built into (± Y-axis direction), the first electrode lead-to-face contact in the first electrode lead (110) (110a between It may form an accommodation space (S) for receiving a portion of a, 110b).
[92]
More specifically, the partition wall portion 213 includes two post part is the outside and the other end of the supporting end from the 211 and 212 up and down directions (± Y-axis direction) as sewojim as received in the interior toward the battery cell 110 space It may form a (S).
[93]
Here, the accommodation space (S) has a first electrode lead (110a, 110b) on the other side of that is, the partition wall portion 213 toward the battery cell 110 may be provided with an open surface opened to be inserted, the upper surface is above the second can be closed by a second spaced portion 215.
[94]
In addition, one surface and the other surface is a receiving space (S) can be closed by the inner surface of the two post portions 211 and 212, respectively.
[95]
That is, the front surface and the upper surface of the receiving space (S) is closed by a respective partition wall portion 213 and a second spaced portion 215, the other surface and one surface, in other words both side faces are in each of the two post portions (211, 212) is closed by the inner side surface facing the battery cell 110 can be an open space opening.
[96]
The accommodation space (S) is partially accommodated in the first electrode lead (110a, 110b) is inserted in the opening face the first electrode lead (110a, 110b) in the process of manufacturing, face-to-face contact of the battery module 10 It can be.
[97]
Accordingly, the accommodation space (S) a first electrode lead (110a, 110b), some of the second other first electrode lead (110c, 110d) and a spaced which is located on the upper side by the spacing portion 215 of the insert to thereby, it is possible to prevent short circuit between the developing which may occur during the manufacturing process of the battery module 10, a first electrode lead (110a, 110b, 110c, 110d).
[98]
A first spaced portion 214 may be formed in a shape protruding in the lateral direction (+ Z-axis direction) from the upper portion of the partition wall 213.
[99]
More specifically, the first spaced portion 214 is formed in a shape protruded toward the opposite direction of the battery cell 100 from the top of the partition wall portion 213, one outside and the other end outside of the first spaced portion 214 are each coupled to two post portions 211 and 212 may be supported from the two post portions (211, 212).
[100]
In other words, it is a first spaced portion 214 and the partition wall portion 213 forms a combined achieve the right angle and may be one or cross section "b" shape as viewed from the other end.
[101]
On the other hand, the first electrode projecting to the outer side of the first spaced portion 214 may be located on top of the first electrode lead (110a, 110b) protruding to the outside of the accommodation space (S), the accommodation space (S) more than lead (110a, 110b) a horizontal direction (+ X-axis direction) may be formed to protrude further.
[102]
This, by using the separation of the first spaced portion 214 containing space (S) a first electrode lead (110a, 110b) and the other first electrode lead located in the upper portion (110c, 110d) protruding toward the outside of the, battery a short phenomenon that may occur between the manufacturing process of the module 10, a first electrode lead (110a, 110b, 110c, 110d) can be prevented.
[103]
A second spaced portion 215 may be formed of a plate-shaped binary lying in the horizontal direction (± X-axis direction) to the upper portion between the two posts 211 and 212 as described above.
[104]
That is, the top of the second spaced portion 215, one outer and the other end each of the two post portions (211, 212) over the partition wall 213 is supported between the top and towards the opposite direction of the battery cell 100 of the outer It may be coupled with the inner side.
[105]
Through this, the second spaced portion 215 is receiving space (S) a first electrode lead (110a, 110b), another first electrode lead (110c which is located a part on top of the accommodated in the accommodation space (S) from the inside of, 110d) and it can be spaced apart.
[106]
As a result, the second spaced portion 215 can prevent the short circuit phenomenon between the first electrode lead (110a, 110b, 110c, 110d) that may occur during the manufacturing process of the battery module 10.
[107]
Support portion 216 can be formed in a shape protruding toward the front from the respective central portion and the lower portion of the partition wall 213, and sensing the bus bar 300 and the face-to-face contact to be supported and mounted for sensing bus bars 300 have.
[108]
This, the support 216 may be composed of a second support (216b) protruding from a lower portion of the first support (216a) and the partition wall portion 213 projects from the central portion of the partition wall 213.
