[0013]

[0030] The present invention will now be described in detail with reference to the accompanying drawings, in which:

[0031] A preferred embodiment of the present invention will be described in detail so that those skilled in the art can easily implement the present invention; however, the present invention may be embodied in various different forms and should not be construed as being limited to the following embodiments.

[0014] In order to clearly explain the present invention, detailed descriptions of parts that are not relevant to the explanation or related known technologies that may obscure the gist of the present invention are omitted, and when referring to components in each drawing in this specification, the same or similar reference symbols are used throughout the specification to refer to the same or similar components.

[0015] Furthermore, the terms and words used in this specification and claims should not be interpreted in a limited way to their ordinary or dictionary meanings, but should be interpreted in a way that is consistent with the technical idea of the present invention, in accordance with the principle that inventors can appropriately define the concepts of terms in order to best explain their inventions.

[0016] [Theme 1] FIG. 1 is an oblique view showing a battery module 1 according to one embodiment of the present invention, FIG. 2 is a plan view showing the battery module 1 according to one embodiment of the present invention as viewed from above, FIG. 3 is an oblique view showing the battery module 1 according to one embodiment of the present invention with the upper case 2 omitted, and FIG. 4 is a partially enlarged view showing the connector module 100 attached to the control unit 10 in the battery module 1 according to one embodiment of the present invention.

[0017] <Battery module 1 structure> Referring to FIG. 1, the battery module 1 may include a plurality of batteries (e.g., a plurality of batteries 2 in FIG. 3). For example, the plurality of batteries 2 may be secondary batteries that can be repeatedly charged and discharged. The plurality of batteries 2 may be regularly arranged in a predetermined pattern, but is not limited thereto. The plurality of batteries 2 may be electrically connected to the outside of the battery module 1.

[0018] The battery module 1 may include a battery case 3. For example, the battery case 3 may be provided to encase a plurality of batteries 2. The battery case 2 may form a part of the outer edge of the battery module 1.

[0019] The battery case 3 may include an upper case 3-1, a side case 3-2, and a lower case 3-3. For example, the upper case 3-1 may form the upper part of the battery module 1 by covering the upper side of the plurality of batteries 2. The side case 3-2 may form the side part of the battery module 1 by covering the lateral side of the plurality of batteries 2. The lower case 3-3 may form the lower part of the battery module 1 by covering the lower side of the plurality of batteries 2.

[0020] At least two of the upper case 3-1, the side case 3-2 and the lower case 3-3 may be integrally formed.

[0021] For example, when the upper case 3-1 and the lower case 3-3 are integrally formed, a plurality of batteries 2 can be placed inside the battery case 3 from which the side case 3-2 has been removed, and then the side case 3-2 can be assembled.

[0022] For example, when the upper case 3-1 and the side case 3-2 are integrally formed, the lower case 3-3 can be assembled after a plurality of batteries 2 are placed inside the battery case 3 from which the lower case 3-3 has been removed.

[0023] The battery module 1 may include a control unit 10. For example, the control unit 10 may be attached to the battery case 3. Specifically, for example, the control unit 10 may be attached to the upper case 3-1. The control unit 10 may be provided to be capable of wireless communication with an external control device.

[0024] The battery module 1 may include a connector module 100 (see FIG. 3). For example, the connector module 100 may electrically connect the control unit 10 and a plurality of batteries 2. The connector module 100 may be attached to and detached from the control unit 10.

[0025] The control unit 10 may include a control PCB 11. For example, the control PCB 11 may be electrically connected to the plurality of batteries 2 via a connector module 100. The control PCB 11 may be provided to be capable of wireless communication with an external control device. The control PCB 11 may be attached to the battery case 3 (or the upper case 3-1). Mounting the control PCB 11 on the upper side may be advantageous for wireless communication.

[0026] The control PCB 11 may be mounted on the PCB frame 13. For example, the PCB frame 13 may be a frame for mounting the control PCB 11. The control PCB 11 may be mounted to the upper case 3-1 via the PCB frame 13. More specifically, the control PCB 11 may be mounted on the PCB frame 13, and the PCB frame 13 may be mounted to the upper case 3-1. Alternatively, the PCB frame 13 may be disposed in a PCB mounting area formed as a recess or dent in the upper case 3-1. In this case, the PCB frame 13 may be visible from the outside when the control unit cover 12 is not attached. However, the present invention is not limited to this.

[0027] The control unit 10 may include a control unit cover 12. For example, the control unit cover 12 may cover the control PCB 11. The control unit cover 12 may be attached to the battery case 3 (or the upper case 3-1). By covering the upper side of the control PCB 11, the control unit cover 12 may protect the control PCB 11 from external impacts.

[0028] Referring to FIG. 2, the control unit 10 may be provided in the upper case 3-1 of the battery case 3. The area of the region where the control unit 10 is mounted may be 20% or less of the area of the upper case 3-1. For example, if the area of the upper case 3-1 is 125,288 mm^2, the area of the region where the control unit 10 is mounted may be 22,752 mm^2. In this case, the area of the region where the control unit 10 is mounted may be approximately 18% of the area of the upper case 3-1. However, the above values are merely examples and may not be limited thereto. By forming the area of the region where the control unit 10 is mounted to be 20% or less of the area of the upper case 3-1, it is possible to effectively utilize the limited space.

[0029] 3 and 4, the connector module 100 may be mounted on the control PCB 11. For example, the connector module 100 may be mounted on the control PCB 11. The connector module 100 may be mounted on the control PCB 11 so as to be located in the space between the control PCB 11 and the control unit cover 12. However, the present invention is not limited to this.

[0030] The connector module 100 may include a plurality of connector modules (e.g., 101, 102). For example, the connector module 100 may include a first connector module 101. The first connector module 101 extends toward one side of the battery case 3 and may be connected to first electrodes of the plurality of batteries 2. The connector module 100 may include a second connector module 102. The second connector module 102 extends toward the other side of the battery case 3 and may be connected to second electrodes of the plurality of batteries 2, the second electrodes having a polarity different from the first electrodes. By including a plurality of connector modules 101, 102, the connector module 100 may be effectively connected to electrodes of the plurality of batteries 2 having different polarities. However, the connector module 100 is not limited to the above, and may also be formed as a single module. For example, one connector module 100 may extend toward the other side of the battery case 3 and may be connected to electrodes of the plurality of batteries 2 having different polarities.

[0031] The first connector module 101 and the second connector module 102 may be spaced apart. For example, the first connector module 101 and the second connector module 102 may be mounted on the control PCB 11 and spaced apart by a predetermined distance. The predetermined distance by which the first connector module 101 and the second connector module 102 are spaced apart may not be particularly limited. In other words, the allowable range of separation in which the first connector module 101 and the second connector module 102 can be mounted on the control PCB 11 may be a range in which the first connector module 101 and the second connector module 102 do not overlap each other to prevent incorrect assembly. However, the above-mentioned numerical ranges are merely examples and may not be limited thereto.

[0032] The first connector module 101 and the second connector module 102 may extend in opposite directions. For example, the first connector module 101 and the second connector module 102 may include conductive portions, and the conductive portions may be coupled to electrodes having different polarities. The conductive portions may correspond to the second conductive portion 310 described below. By arranging the first connector module 101 and the second connector module 102 at a distance from each other, the length of the conductive portion (e.g., the second conductive portion 310) extending for electrical connection can be effectively reduced in proportion to the distance between them. Although the conductive portion is described above as being included in the connector module, the conductive portion may be an FFC coupled to the connector module and may be described and understood as a separate configuration.

[0033] The connector module 100 may include a first connector 200 and a second connector 300. For example, the first connector 200 may be attached (or coupled) to the control unit 10 (or the control PCB 11) so as to be electrically connected thereto. The second connector 300 may be attached to and detached from the first connector 200. Specifically, for example, the second connector 300 may be hook-coupled (or engaged) with the first connector 200. When the connector module 100 includes a plurality of connector modules 101, 102, each of the plurality of connector modules 101, 102 may include the first connector 200 and the second connector 300.

[0034] 5 is an exploded perspective view showing a connector module 100 according to an embodiment of the present invention. The description of the above embodiment can be applied equally or similarly to this embodiment.

[0035] <Structure of Connector Module 100> The connector module 100 may be formed by mounting the second connector 300 to the first connector 200. By mounting the second connector 300 to the first connector 200, the control PCB 11 and the plurality of batteries 2 may be electrically connected.

[0036] 5, the first connector 200 may include a first conductive part 210. For example, the first conductive part 210 may be electrically connected to the control unit 10. Specifically, the first conductive part 210 may be electrically connected to the control PCB 11.

[0037] The first connector 200 may include a first connector housing 220. For example, the first connector housing 220 may form an outer edge of the first connector 200. An insertion space V into which the second connector 300 may be inserted may be formed inside the first connector housing 220 (see FIG. 18, etc.).

[0038] A hole 230 may be formed in the first connector 200. For example, the first connector housing 220 may be formed with a hole 230 that is provided to allow a part of the second connector 300 (or a binding portion 322, which will be described later) to be hook-coupled. A plurality of holes 230 may be formed.

[0039] The second connector 300 may include a second conductive part 310. For example, the second conductive part 310 may extend to a predetermined length so as to be electrically connected to a plurality of batteries 2. The second conductive part 310 may include a folded portion during extension. As another example, the second conductive part 310 may be a flat flexible cable (FFC).

[0040] Although the above description has been given with the second conducting portion 310 being included in the second connector 300, the second conducting portion 310 is an FFCC connected to the second connector 300 and may be described and understood as a separate configuration.

[0041] The second connector 300 may include a conductive film 311. For example, the conductive film 311 may be disposed on the second conductive part 310. Specifically, the conductive film 311 may be disposed between the second conductive part 310 and the second connector housing 320.

[0042] Although the conductive film 311 is described above as being included in the second connector 300, the conductive film 311 may be described and understood as being of a different configuration.

[0043] The second connector 300 may include a second connector housing 320. For example, the second connector housing 320 may form an outer edge of the second connector 300. The second connector housing 320 may be inserted into the insertion space V inside the first connector housing 220.

[0044] The second connector 300 may include a binding portion 322. The binding portion 322 may be rotatable within the second connector housing 320 to a predetermined extent. For example, the binding portion 322 may be rotatable toward or away from the second connector housing 320 during insertion into the first connector 200. In other words, the binding portion 322 may be rotated to include a section where a difference in height occurs at the end of the binding portion 322 during insertion into the first connector 200. The binding portion 322 (or the end of the binding portion 322) may pass through the hole 230 of the first connector 200 and be bound to the first connector housing 220, thereby binding the first connector 200 and the second connector 300 together.

[0045] The connector module 100 may include a fastening housing 400. The fastening housing 400 may limit movement of the second conducting part 310 relative to the second connector housing 320. By limiting the movement of the second conducting part 310, the fastening housing 400 may maintain stable electrical contact between the first conducting part 210 and the second conducting part 310.

[0046] Fig. 6 is a vertical cross-sectional view showing a state in which a connector module 100 is attached to a control unit 10 according to an embodiment of the present invention, and Fig. 7 is a vertical cross-sectional view showing a cross-section of a control unit cover 12 according to an embodiment of the present invention. The description of the above embodiment can be applied equally or similarly to this embodiment. The following description will be made with reference to Figs. 6 and 7.

[0047] <Structure of control unit 10> The control PCB 11 may be disposed on a PCB frame 13 disposed in a PCB mounting area formed as a recess or dent in the upper case 3-1. The control PCB 11 may include an area where the connector module 100 is disposed and an area where the connector module 100 is not disposed. The area where the connector module 100 is not disposed may be an area of the control PCB 11 other than the area where the connector module 100 is disposed.

[0048] The control unit cover 12 can define an accommodation space for accommodating the connector module 100. For example, the control unit cover 12 can be disposed on the battery case 3 (or the upper case 3-1) to cover the control PCB 11, thereby defining an accommodation space for accommodating the connector module 100. As another example, the control unit cover 12 can be attached to the battery case 3 (or the upper case 3-1) to cover the top of the connector module 100.

[0049] In the area where the connector module 100 is not disposed, the height H1 from the control PCB 11 to the control unit cover 12 can be less than 4 mm (for example, 3.92 mm).

[0050] The control unit cover 12 may include a cover recess 12-1. The cover recess 12-1 may be formed by recessing a predetermined amount in an area of the control unit cover 12 facing the connector module 100. Specifically, for example, in the area where the connector module 100 is disposed, the height from the control PCB 11 to the control unit cover 12 (or the height H2 of the cover recess 12-1) may be 5 mm or less.

[0051] The area of the cover recess 12-1 facing the connector module 100 may include a curved area. For example, the area facing the connector module 100 may be formed with a gently sloping area, thereby minimizing damage to the connector module 100 and the control unit cover 12 even in the event of a collision or contact with the connector module 100.

[0052] The predetermined recessed extent (or height) H4 of the cover recess 12-1 can be equal to or greater than two-thirds the thickness of the remaining unrecessed portion. For example, the thickness of the cover recess 12-1 of the control unit cover 12 can be 0.5 mm, and the thickness of the remaining portion can be 1.5 mm.

[0053] The thickness of the cover recess 12-1 may be 40% or less of the thickness of the remaining portion. For example, the thickness of the cover recess 12-1 of the control unit cover 12 may be 0.5 mm, and the thickness of the remaining portion may be 1.5 mm.

[0054] In this case, the predetermined recessed degree (H4) can be 1 mm.

[0055] The height H3 of the connector module 100 may be smaller than the height H2 of the cover recess 12-1. For example, when the height H2 of the cover recess 12-1 is 5 mm or less, the height of the connector module 100 may be 4 mm or less. Specifically, the height H2 of the cover recess 12-1 may be 4.92 mm, and the height H3 of the connector module 100 may be 3.9 mm. However, the above numerical ranges are merely examples and may not be limited thereto.

[0056] The distance from the control PCB 11 to the control unit cover 12 may be within a range of 3.9 mm to 5 mm. For example, the distance from any region of the control PCB 11 to the control unit cover 12 may be within a range of 3.9 mm to 5 mm. Specifically, for example, in the region of the control PCB 11 where the connector module 100 is disposed, the distance from the control PCB 11 to the control unit cover 12 may be 4.92 mm. Furthermore, in the remaining region of the control PCB 11, the distance from the control PCB 11 to the control unit cover 12 may be 3.92 mm. However, the above-mentioned numerical ranges are examples with an error range of 0.05 mm and may not be limited to these.

[0057] As described above, providing the control unit cover 12 with the cover recess 12-1 prevents the height of the control unit cover 12 itself from being increased by the connector module 100, thereby effectively reducing the size of the control unit cover 12. Furthermore, by making the thickness of the remaining area of the control unit cover 12 where the cover recess 12-1 is not formed thicker than the thickness of the cover recess 12-1, the overall rigidity of the control unit cover 12 can be effectively reinforced.

[0058] 8 is a perspective view showing the arrangement of the conductive portion 310 according to an embodiment of the present invention. The description of the above embodiment can be applied equally or similarly to this embodiment.

[0059] <Structure of Conductive Part 310> The second connector 300 may include a second conductive portion 310. Although the second conductive portion 310 is described as being included in the second connector 300, the second conductive portion 310 may be an FFC coupled to the second connector 300 and may be described and understood as a separate configuration.

[0060] The second conducting part 310 may be electrically connected to the plurality of batteries 2. For example, the second conducting part 310 may extend a predetermined length so as to be electrically connected to the plurality of batteries 2. The predetermined length may be a length that extends from the second connector housing 320 to one side (or another side) of the battery case 3 and allows electrical connection with the plurality of batteries 2.

[0061] The second conductive part 310 may include folded portions 312 and 313 during extension. For example, the second conductive part 310 may include a first folding part 312 and a second folding part 313 during extension. Specifically, the second conductive part 310 may be an FFC, and electrical connection may be maintained even when folded. As a result, folding the second conductive part 310 during extension may maximize spatial efficiency and allow effective connection to multiple batteries 2. In addition, the folding of the second conductive part 310 may be structurally adaptively designed and realized in various paths, thereby effectively realizing electrical connection paths.

[0062] An FFC (flexible flat cable) is a cable (e.g., a ribbon-shaped cable) that is connected via a connector housing, while an FPC (flexible printed circuit) is a printed circuit, and an FFC can be taller than an FPC. However, according to the above-described embodiment, the connector module 100 is formed with a height of 4 mm or less, thereby maximizing spatial efficiency.

[0063] [Theme 2] Fig. 9 is a perspective view showing a first connector 200 according to an embodiment of the present invention as viewed from one direction, and Fig. 10 is a perspective view showing a first connector 200 according to an embodiment of the present invention as viewed from another direction. The description of the above embodiment can be applied equally or similarly to this embodiment. The following description will be made with reference to Figs. 9 and 10.

[0064] <Reinforcement structure of first connector 200> The first connector 200 may include a protruding portion 221. For example, the protruding portion 221 may be formed to protrude from the inner bottom surface of the first connector housing 220. In addition, the first conducting part 210 may be attached to the protruding portion 221.

[0065] The protruding portion 221 may include a body portion 222. For example, the body portion 222 may protrude at a first height h1 from the inner bottom surface of the first connector housing 220. Specifically, for example, when the height H3 of the first connector 200 is 3.5 mm to 4 mm, the first height h1 may be in the range of 0.4 mm to 0.6 mm.

[0066] The raised portion 221 may include a partition 223. For example, the partition 223 may be formed to protrude from the body portion 222. The partition 223 may protrude from the inner bottom surface to a second height h2 that is higher than the first height h1. The partition 223 may protrude from the body portion 222 in the form of a plurality of partitions. When viewed from above, the body portion 222 may be formed to include an area where the partition 223 is to be disposed, and may extend toward the opening 220-1.

[0067] A plurality of first conducting parts 210 may be arranged in a direction crossing the insertion direction DI of the second connector 300. For example, the first conducting parts 210 may be formed in the form of a plurality of connecting terminals and arranged in the crossing direction. As another example, the first conducting parts 210 may have a form in which a plurality of connecting terminals are alternately arranged with the partition walls 223. The alternate arrangement may be to prevent short-circuiting of the connecting terminals.

[0068] The body portion 222 may extend parallel to the direction in which the first conductive portion 210 is disposed. For example, the length w1 of the body portion 222 in a direction transverse to the insertion direction DI of the second connector 300 may be in the range of 10 mm to 13 mm. The width w2 of each partition wall 223 may be in the range of 0.5 mm to 0.7 mm. The partition walls 223 may include a plastic material (e.g., engineering plastic). For example, the partition walls 223 may be PA9T, but are not limited thereto. When the partition walls 223 are formed from the above-mentioned plastic material, they may have long-term heat resistance at high temperatures, strong resistance to various chemicals, and the general mechanical properties obtained by engineering plastics.

[0069] The first connector 200 is provided with a reinforcing structure, the body 222, and the raised portion 221 including the partition 223, which effectively prevents the partition 223 from being damaged or broken due to direct collision or interference with the second connector housing 320 when the second connector 300 is inserted. The body 222 is structured to fill the space below the partition 223, which complements the strength of the partition, allowing the partition to be less easily damaged and to firmly maintain its shape.

[0070] 11 is a perspective view showing a depression line 224 according to one embodiment of the present invention. The explanations regarding the above embodiment can be applied equally or similarly to this embodiment.

[0071] <Depression line 224> The body portion 222 may include a recessed line 224. For example, the recessed line 224 may be recessed into the body portion 222.

[0072] The recessed lines 224 may be formed alternately with the partition walls 223. As a specific example, when viewed from the opening 220-1 side, the recessed lines 224 may be formed alternately between the partition walls 223.

[0073] The recess line 224 may extend toward the opening side 220-1, away from the partition wall 223. For example, the recess line 224 may extend toward the opening side 220-1, away from the partition wall 223, in a direction parallel to the direction in which the second connector 300 is inserted.

[0074] The recessed line 224 may be provided to guide the comb structure 350, which will be described later. For example, the recessed line 224 may have a shape corresponding to the comb structure 350. The recessed line 224 may be recessed into the body portion 222 so that the comb structure 350 can be guided during insertion.

[0075] By providing the recess line 224 on the body portion 222, when the second connector 300 is inserted into the first connector 200, the comb-shaped structure 350 does not deviate from the insertion path, and damage or breakage of the partition 223 due to direct collision or interference with the second connector housing 320 can be effectively prevented.

[0076] The recessed line 224 may be provided so that a portion of the comb structure 350 is seated when the comb structure 350 is inserted into the partition 223. For example, when an end of the comb structure 350 is inserted and seated between the partitions 223, a portion of the comb structure 350 on the comb base 360 side may be seated in the recessed line 224. By seating a portion of the comb structure 350 in the recessed line 224, vibrations due to vibrations or impacts can be further prevented when the first connector 200 and the second connector 300 are coupled, thereby maintaining a stable electrical connection.

[0077] FIG. 12 is a perspective view showing the comb structure 350 of the second connector 300 according to one embodiment of the present invention, FIG. 13a is a bottom view showing the comb structure 350 of the second connector 300 according to one embodiment of the present invention from the bottom, and FIG. 13b is a perspective view of the second connector according to one embodiment of the present invention from the bottom.

[0078] The description of the above embodiment can be applied to this embodiment in the same or similar manner. The following description will be made with reference to Figures 12, 13a and 13b.

[0079] <Open Section 340> The second connector 300 may have an opening 340. For example, the opening 340 may be a space in which the partition 223 is positioned when the first connector 200 and the second connector 300 are coupled together. Specifically, the opening 340 may refer to a space between a protruding portion 321-2 and the comb-shaped structure 350, which will be described later. Alternatively, the opening 340 may refer to a space between the comb-shaped structures 350. When the first connector 200 and the second connector 300 are coupled together, the partition 223 may be inserted into the space between the protruding portion 321-2 and the comb-shaped structure 350 or the space between the comb-shaped structures 350.

[0080] <Comb structure 350> The second connector 300 may include a comb-shaped base portion 360. For example, the comb-shaped base portion 360 may be a portion that faces the body portion 222 when the second connector 300 is inserted into the first connector 200.

[0081] The second connector 300 may include a comb structure 350. For example, the comb structure 350 may protrude from a comb base portion 360 toward the first connector 200. As another example, the comb structure 350 may have a shape corresponding to the protrusion 221 of the first connector 200.

[0082] The second conductive part 310 may be inserted into a recessed portion surrounded by a frame (e.g., frame 321 in FIGS. 25 and 28) and the binding part 322. A plurality of holes 350-1 are formed through the spaces between the comb-shaped structures 350, and the first conductive part 210 may contact a lower surface of the second conductive part 310 through the through-formed holes 350-1. In this case, the first conductive part 210 may contact one surface of the second conductive part 310 and be electrically connected to it.

[0083] Based on the direction in which the second connector 300 is inserted, the ratio of the length of the portion of the second connector 300 inserted into the first connector 200 to the length of the comb structure 350 may be in the range of 1 to 3. For example, based on the direction in which the second connector 300 is inserted, the length of the comb structure 350 may be in the range of 2 mm to 4 mm, and the length of the portion of the second connector 300 inserted into the first connector 200 may be in the range of 4 mm to 6 mm. More specifically, if the length of the comb structure 350 is 2 mm and the length of the inserted portion is 6 mm, the ratio of the length of the comb structure 350 to the length of the portion of the second connector 300 inserted into the first connector 200 may be 3. Also, if the length of the comb structure 350 is 4 mm and the length of the inserted portion is 4 mm, the ratio of the length of the comb structure 350 to the length of the portion of the second connector 300 inserted into the first connector 200 may be 1. However, the above-mentioned ratios are not limitative.

[0084] The second connector 300 may include protruding portions 321-2. For example, the protruding portions 321-2 may protrude from both ends of the second connector housing 320 to surround both sides of the protruding portion 221 when the second connector 300 is inserted into the first connector 200. Furthermore, the protruding portions 321-2 may extend from both ends of the second connector housing 320 in the direction in which the second connector 300 is inserted. Alternatively, the protruding portions 321-2 may protrude from the second connector housing 320 toward the inner bottom surface when the second connector 300 is inserted into the first connector 200. The protruding portions 321-2 may be configured to surround the protruding portions 221 of the first connector 200, thereby guiding the insertion of the second connector 200. Furthermore, guiding the second connector 200 may prevent damage or breakage of the bulkhead 223 and prevent short-circuiting of the connecting terminals of the first conductive part 210.

[0085] Fig. 14 is a plan view showing a state in which the first connector 200 and the second connector 300 according to one embodiment of the present invention are coupled, Fig. 15 is a vertical cross-sectional view showing a cross section taken along the BB line when the first connector 200 and the second connector 300 according to one embodiment of the present invention are coupled, and Fig. 16 is a vertical cross-sectional view showing a cross section taken along the CC line when the first connector 200 and the second connector 300 according to one embodiment of the present invention are coupled. The explanations regarding the above-mentioned embodiments can be applied equally or similarly to this embodiment. The following description will be made with reference to Figs. 14 to 16.

[0086] <Relationship between the raised portion 221, the comb-shaped structure 350, and the comb-shaped base portion 360> The second connector 300 may be inserted and attached inside the first connector 200. In this case, the binding portion 322 of the second connector 300 may be hook-coupled to the hole 230 of the first connector 200.

[0087] The fastening housing 400 may limit the movement of the second conducting part 310. For example, the fastening housing 400 may be attached to the second connector housing 320 so as to limit the movement of the second conducting part 310.

[0088] Referring to the cross section taken along line BB, the comb structure 350 may be inserted between the partition walls 223. For example, the comb structure 350 may be provided to fit into the space between the partition walls 223 when the second connector 300 is inserted and attached to the first connector 200. In other words, the comb structure 350 and the partition walls 223 may have corresponding structures to enable insertion coupling.

[0089] Referring to the cross section taken along line CC, the comb base portion 360 can be aligned with the body portion 222. For example, the comb base portion 360 can be provided to face and align with the body portion 222 when the second connector 300 is inserted and attached to the first connector 200. In other words, the comb base portion 360 and the body portion 222 can have corresponding structures to align with each other when they face each other.

[0090] [Theme 3] Fig. 17 is a plan view showing a first connector 200 according to one embodiment of the present invention as seen from above, and Fig. 18 is a longitudinal cross-sectional view showing a cross section of first connector 200 according to one embodiment of the present invention. The explanations regarding the above-mentioned embodiments can be applied equally or similarly to this embodiment. The following explanation will be made with reference to Figs. 17 and 18.

[0091] <Structure of the first connector housing 220> The first connector 200 may include a first connector housing 220. The first connector housing 220 may have an opening 220-1 formed therein so that the second connector 300 may be inserted therein.

[0092] The first connector housing 220 may define an insertion space V. For example, the insertion space V may be defined by an upper portion 220-2, a side portion 220-3, and a lower portion 220-4 of the first connector housing 220. Specifically, the insertion space V may be defined by being surrounded by an inner surface of the upper portion 220-2, an inner surface of the side portion 220-3, and an inner surface of the lower portion 220-4.

[0093] The lower portion 220-4 may be provided with a first conductive part 21 to be electrically connected to the second connector 300.

[0094] The first connector housing 220 may have a hole 230 formed through the upper portion 220-2 so that the second connector 300 can be hooked.

[0095] The first connector housing 220 may include a protruding rib 225. For example, the protruding rib 225 may be formed on an edge of the upper portion 220-2. Specifically, the protruding rib 225 may be formed to protrude from an edge of the upper portion 220-2 on a side where the second connector 300 is inserted. The protruding rib 225 may reinforce the structural rigidity of the upper portion 220-2 in which the hole 230 is formed.

[0096] 19 is a plan view showing the protruding rib 225 of the first connector 200 according to one embodiment of the present invention. The description of the above embodiment can be applied equally or similarly to this embodiment.

[0097] <Structure of the protruding rib 225> The edge of the upper portion 220-2 on the opening 220-1 side may include a protruding rib 225. For example, the upper portion 220-2 may include a protruding rib 225 that protrudes in a direction from the hole 230 toward the opening 220-1 side.

[0098] The distance A from the edge of the hole 230 on the opening 220-1 side to the end of the protruding rib 225 can be in the range of three to four times the thickness T of the upper part 220-2. For example, the thickness T of the upper part 220-2 can be in the range of 0.4 mm to 0.5 mm. In this case, the distance A can be in the range of 1.2 mm to 2.0 mm.

[0099] The protruding degree A' of the protruding rib 225 may be determined depending on the thickness T of the upper portion 220-2. For example, the thicker the thickness T of the upper portion 220-2, the greater the protruding degree A'.

[0100] The protruding rib 225 formed on the first connector housing 220 can reinforce the rigidity of the upper portion 220-2 in which the hole 230 is formed. For example, even if an external force is applied, the pressure is dispersed in proportion to the extent to which the protruding rib 225 protrudes, thereby preventing cracks or damage to the upper portion 220-2.

[0101] Cracks in the upper part 220-2 can occur in a diagonal direction relative to the edge where the protruding rib 225 is formed, and as the protruding rib 225 is formed to protrude, the diagonal length g is also extended, thereby reinforcing the strength in the diagonal direction.

[0102] 20 is a plan view showing the hole 230 of the first connector 200 according to an embodiment of the present invention. The description of the above embodiment can be applied equally or similarly to this embodiment.

[0103] <Hall 230 Structure> A hole 230 may be formed in the first connector housing 220. For example, the hole 230 may include a rounded edge on the opening 220-1 side. The rounded edge of the hole 230 may have a fillet radius R of 0.3 mm to 1 mm.

[0104] The hole 230 may include a plurality of holes. For example, the plurality of holes may be formed along a direction parallel to the edge of the upper portion 220-2 on the opening 220-1 side. The protruding rib 225 may extend parallel to the direction in which the plurality of holes are formed.

[0105] When the protruding rib 225 is formed to extend along the plurality of holes, it can effectively prevent cracks or damage to the upper part 220-1 where the plurality of holes are formed. Even if an external force is applied, the pressure is dispersed in proportion to the extent to which the protruding rib 225 extends, so it can prevent cracks or damage to the upper part 220-2.

[0106] Fig. 21 is a perspective view showing an internal rib 226 according to one embodiment of the present invention, and Fig. 22 is a front view showing an internal rib 226 according to one embodiment of the present invention. The description of the above embodiment can be applied equally or similarly to this embodiment. The following description will be made with reference to Figs. 21 and 22.

[0107] <Structure of the internal rib 226> The upper portion 220-2 may include an internal rib 226. For example, the internal rib 226 may protrude toward the insertion space V. The internal rib 226 may also protrude in a direction parallel to the direction DI in which the second connector 300 is inserted.

[0108] The internal ribs 226 may not interfere with the insertion of the second connector 300 into the insertion space V. For example, the internal ribs 226 may be formed in an area other than the insertion path of the second connector 300 toward the insertion space V. As another example, the surface of the second connector housing 320 facing the surface of the upper part 220-2 of the first connector housing 220 on which the internal ribs 226 are formed may be formed in a corresponding structure.

[0109] The internal rib 226 may protrude by 1 to 2 times the thickness T of the upper portion 220-2. For example, if the thickness T of the upper portion 220-2 is in the range of 0.4 mm to 0.5 mm, the internal rib 226 may protrude by 0.8 mm to 1.0 mm. When the protrusion degree of the internal rib 226 is designed to be in the range of 1 to 2 times the thickness T of the upper portion 220-2, rigidity can be effectively ensured, regardless of further protrusion. However, the above numerical ranges are merely examples and may not be limiting.

[0110] The upper portion 220-2 may include a plurality of internal ribs 226. For example, the internal ribs 226 may protrude toward the insertion space V. Also, the internal ribs 226 may be formed symmetrically around the protruding rib 225.

[0111] The plurality of internal ribs 226 may be formed alternately with the holes 230. For example, the plurality of internal ribs 226 may be formed alternately with the holes 230 based on the inner surface of the upper portion 220-2. As a specific example, the holes 230 may be two holes, and the internal ribs 226 may include three internal ribs formed alternately and spaced apart on either side of the two holes 230.

[0112] The internal ribs 226 can reinforce the rigidity of the upper portion 220-2 having a small thickness T. The internal ribs 226 can also reinforce the rigidity of the upper portion 220-2 in which the holes 230 are formed.

[0113] 23 is a front view showing the arrangement of the protruding ribs 225 and the internal ribs 226 according to one embodiment of the present invention. The explanations regarding the above-mentioned embodiment can be applied equally or similarly to this embodiment.

[0114] <Arrangement of the protruding ribs 225 and the internal ribs 226> The first connector housing 220 may include a protruding rib 225 and an internal rib 226. For example, the first connector housing 220 may include a protruding rib 225 that protrudes from an edge of the upper portion 220-2 on the opening 220-1 side in a direction from the hole 230 toward the opening 220-1 side. The first connector housing 220 may also include an internal rib 226 that protrudes from the upper portion 220-2 toward the insertion space V.

[0115] The protruding rib 225 and the internal rib 226 may include overlapping regions. For example, the protruding rib 225 and the internal rib 226 may include overlapping regions along their edges when viewed from the opening 220-1 side in the direction DI in which the second connector 300 is inserted.

[0116] 23, the internal rib 226 may protrude toward the insertion space V by a predetermined protruding length B1. The internal rib 226 may also extend in a direction along the edge of the upper portion 220-2 on the opening 220-1 side by a predetermined extension length B2. In this case, the protruding rib 225 and the internal rib 226 may have a predetermined overlap length B3. The length of the overlapping region may be the overlap length B3. For example, the overlap length B3 may be in the range of 25% to 50% of the length B2 along the edge of the internal rib 226. The greater the overlap length B3, the greater the reinforcement strength.

[0117] A plurality of internal ribs 226 may be formed, and the plurality of internal ribs 226 may have different widths. Specifically, the internal ribs 226 may include three internal ribs. The three internal ribs may include a central rib formed between two holes and having a first width, and outer ribs formed outside the two holes and having a second width greater than the first width.

[0118] Of the three internal ribs, the central rib may protrude toward the insertion space to a greater extent than the outer ribs. The central rib may be more likely to come into contact with the second connector 300 when viewed from the insertion path when the second connector 300 is inserted into the insertion space. By protruding the central rib more than the outer ribs, strength can be reinforced and damage due to contact can be prevented. Furthermore, the central rib may also perform a guiding function when the second connector 300 is inserted. The central rib may extend to the protruding region of the protruding rib 225. Alternatively, the central rib may extend further toward the opening 220-1 than the outer ribs. Various embodiments are possible for the width and protrusion of the internal rib, depending on the number, position, and size of the holes 230.

[0119] The protruding degrees A' and B1 of the protruding rib 225 and the internal rib 226 may be determined according to the thickness T of the upper portion 220-2. When the protruding degrees A' and B1 are determined according to the thickness T of the upper portion 220-2, the rigidity of the thin thickness T of the upper portion 220-2 in which the holes 230 are formed can be adaptively reinforced according to the structure.

[0120] [Theme 4] <Structure for preventing separation of fastening housing 400> FIG. 24 is a perspective view of a second connector according to an embodiment of the present invention.

[0121] Referring to FIG. 24, the connector module 100 may include a first connector 200 and a second connector 300 (see FIG. 5).

[0122] The first connector 200 may be electrically connected to the control unit 10. The first connector 200 may include a first connector housing 220 and a first conductive portion 210.

[0123] The first connector housing 220 may form the exterior of the first connector 200. For example, the first connector housing 220 may have a housing shape having a structure formed with an inward recess. Specifically, the first connector housing 220 may include an opening 220-1 that is open on one side and a first recessed portion 220a formed by recessing inward from the opening 220-1. The second connector 300 may be inserted and coupled into the first recessed portion 220a.

[0124] The first conductive part 210 may be connected to the first connector housing 220 and electrically connected to the control unit.

[0125] The second connector 300 may be electrically connected to the first connector 200. For example, the second connector 300 may be inserted into and coupled to the first connector 200. Specifically, the second connector 300 may be inserted into a first recess 220a formed inside the first connector housing 220 and coupled to the first connector 200. For example, one side of the second connector 300 may be electrically connected to the first connector 200, i.e., the first conductive part 210, and the other side of the second connector 300 may be electrically connected to the plurality of battery cells 2.

[0126] The second connector 300 may include a second connector housing 320 , a second conductive part 310 and a fastening housing 400 .

[0127] The second connector housing 320 forms the exterior of the second connector 300 and can be configured to be inserted into and coupled to the first connector 200. In other words, the second connector housing 320 can be inserted into the first recessed portion 220a of the first connector 200 and coupled integrally with the first connector 200.

[0128] The second connector housing 320 may include a frame 321 and a binding portion 322 (see FIG. 24).

[0129] The frame 321 can be inserted into and coupled to the first connector 200. That is, the frame 321 can be inserted into the first recessed portion 220a of the first connector housing 220 and structurally coupled to the first connector 200.

[0130] The binding part 322 may be connected to one surface of the frame 321 and coupled to the first connector 200. For example, the binding part 322 may be connected to the upper surface of the frame 321. The binding part 322 may be coupled to the inner upper surface of the first connector housing 220 while connected to the upper surface of the frame 321, thereby being coupled to the first connector 200.

[0131] In this case, the fastening portion 322 may be coupled to the first connector 200 by a hook coupling. For example, the fastening portion 322 may have a lever shape. Specifically, a through-hole 230 may be formed in the top surface of the first connector housing 220 so that the top surface of the first connector housing 220 and the first recessed portion 220a are in communication with each other, and the fastening portion 322 may be coupled to the through-hole in the top surface of the first connector housing 220.

[0132] More specifically, with the front of the binding portion 322 connected to the frame 321, the rear of the binding portion 322 can move upward or downward based on the direction in which the second connector 300 is inserted into the first connector 200.

[0133] With the binding portion 322 spaced apart from the second conducting portion 310 by a predetermined distance, the second connector 300 is inserted into and coupled to the first connector 200, and the binding portion 322 moves downward and then upward to engage with the perforated portion on the upper surface of the first connector housing 220, thereby binding the first connector 200 and the second connector 300 to each other by the binding portion 322. In this case, the binding portion 322 may also be spaced apart from the second conducting portion 310 by a predetermined distance.

[0134] Conversely, when binding portion 322 moves downward due to an external force from a user or the like, binding is released and second connector 300 can be detached from first connector 200.

[0135] 25 is an enlarged view of the second connector according to one embodiment of the present invention, and referring to FIG. 25, binding portion 322 may include protruding portion 322-1 formed on the upper surface thereof. When first connector 200 and second connector 300 are coupled, a user can press protruding portion 322-1 of binding portion 322 to decouple second connector 300 from first connector 200.

[0136] The second conducting unit 310 may be electrically connected to the first conducting unit 210 by being at least partially inserted into the frame 321. That is, the second conducting unit 310 is configured to be electrically connected to a plurality of battery cells and may receive electrical signals from the plurality of battery cells and transmit the signals to the first conducting unit 210. For example, the second conducting unit 310 may include a flexible flat cable (FFC).

[0137] An area surrounded by the frame 321 and the binding part 322 and open on one side is formed inside the frame 321, and the second conductive part 310 can be inserted and coupled to the frame 321 so as to be surrounded by the frame 321 and the binding part 322.

[0138] The fastening housing 400 may fasten the second connector housing 320 and the second conducting part 310 to each other. For example, the fastening housing 400 may enclose the second connector housing 320 with the second conducting part 310 inserted and coupled to the second connector housing 320. Specifically, the fastening housing 400 may function to crimp and grip the second connector housing 320 and the second conducting part 310 to prevent the second conducting part 310 from coming off the second connector housing 320.

[0139] At the same time, the fastening housing 400 has a stepped structure 410-1 that contacts one surface of the binding part 322, thereby restricting the binding part 322 from coming off the frame 321. In other words, the structure in which a portion of the binding part 322 is locked to the fastening housing 400 can prevent the binding part 322 from being distorted or moved excessively upward.

[0140] FIG. 26 is a front view of a fastener housing according to one embodiment of the present invention.

[0141] Referring to FIG. 26, the fastener housing 400 can include a fastener body 410 and a fastener portion 420 .

[0142] The fastening body 410 can contact the second connector housing 320 and the second conducting part 310 to fasten the second connector housing 320 and the second conducting part 310. For example, while positioned behind the binding part 322, the fastening body 410 can wrap around a part of the rear of the binding part 322 and crimp the second conducting part 310, thereby fastening the second connector housing 320 and the second conducting part 310 to each other.

[0143] The fastening body 410 may include a first fastening body 411 and a second fastening body 412 .

[0144] The first fastening body 411 may be located behind the binding portion 322 based on the direction in which the second connector 300 is inserted into the first connector 200. For example, the first fastening body 411 may be located behind the binding portion 322 and formed and arranged to extend on both sides when viewed in the direction in which the second connector 300 is inserted into the second connector 300. That is, the first fastening body 411 may be formed along the rear of the binding portion 322.

[0145] The second fastening body 412 may be formed on both sides of the first fastening body 411 and may enclose a portion of both sides of the binding portion 322. In this case, the portion of the second fastening body 412 enclosing a portion of both sides of the binding portion 322 may include a stepped portion 410-1. That is, the fastening body 410 may include the stepped portion 410-1 that contacts one surface of the binding portion 322 and is formed in a stepped shape. However, the stepped portion 410-1 does not necessarily have to be formed on both sides of the binding portion 322, and may be formed corresponding to at least one of the two sides of the binding portion 322.

[0146] When viewed in the direction in which the second connector 300 is inserted, the binding portion 322 can be restricted from moving upward by being locked by the stepped portion 410-1 of the fastening body 410. For example, when the rear of the binding portion 322 moves upward, the stepped portion 410-1 can come into contact with the rear of the binding portion 322.

[0147] 25, when viewed from the front of binding portion 322, step portion 410-1 may have a first surface 410a formed on the upper side of binding portion 322, a second surface 410b having one side connected to the lower side of first surface 410a and in contact with the upper surface of binding portion 322, and a third surface 410c connected to the other side of second surface 410b and formed along the side of binding portion 322. In this case, the upper surface of binding portion 322 is engaged with second surface 410b, and therefore may be located below an extension line of second surface 410b. In other words, the movement radius of binding portion 322 may be limited so that the upper surface of binding portion 322 does not move above second surface 410b.

[0148] The binding portion 322 is engaged with the second surface 410b, so that the movement of the binding portion 322 above the second surface 410b can be restricted. With this structure, the binding portion 322 is restricted to a predetermined radius, so that excessive distortion or separation of the binding portion 322 above the frame 321 can be prevented.

[0149] As a result, the problem of the binding portion 322 floating upward and being deformed or damaged by firing is prevented in advance, thereby increasing the structural stability of the second connector 300 and improving the connection stability of the first connector 200 and the second connector 300.

[0150] FIG. 27 is a close-up view of a tie and fastener housing according to one embodiment of the present invention.

[0151] 27, the upper surface of the first fastening body 411 may be located lower than the upper surface of the protruding portion 322-1 of the binding portion 322. That is, the protruding portion 322-1 of the binding portion 322 may be formed higher than the extension of the upper surface of the first fastening body 410. Because the protruding portion 322-1 of the binding portion 322 is located higher than the upper surface of the first fastening body 411, a user can more easily press and handle the protruding portion, thereby increasing the convenience of use of the connector module 100.

[0152] In this case, the distance S between the upper surface of the first fastening body 411 and the upper surface of the protruding portion 322-1 of the binding portion 322 may be 0.5 mm to 0.7 mm. If the distance S between the upper surface of the first fastening body 411 and the upper surface of the protruding portion 322-1 of the binding portion 322 is less than 0.5 mm, it may be difficult to distinguish between the upper surface of the first fastening body 411 and the upper surface of the protruding portion 322-1 of the binding portion 322, reducing the convenience of use of the connector module 100. Conversely, if the distance S between the upper surface of the first fastening body 411 and the upper surface of the protruding portion 322-1 of the binding portion 322 exceeds 0.7 mm, the height of the protruding portion 322-1 of the binding portion 322 becomes too high, increasing the overall height of the connector module 100 and potentially occupying the internal space of the battery module 1 inefficiently.

[0153] Furthermore, when the height of the first fastening body 411 is L1 and the height of the second fastening body 412 is L2, the relationship 0.3≦L1 / L2≦0.5 can be satisfied. If L1 / L2 is less than 0.3, the difference in height between the first fastening body 411 and the second fastening body 412 is small, making it difficult to determine the position of the protruding portion 322-1 of the binding portion 322 and reducing the convenience of use of the connector module 100. Conversely, if L1 / L2 is more than 0.5, the height of the first fastening body 411 becomes too small, which may cause the first fastening body 411 to be easily damaged, and the height of the second fastening body 412 becomes too large, which may increase the overall height of the connector module 100.

[0154] The height L1 of the first fastening body 411 (or, in other words, the thickness of the first fastening body 411) may be 0.8 to 1.2 mm. Due to the thickness of the first fastening body 411, when pressing the binding part 322, the hand can be supported to prevent excessive downward pressure. This allows the binding part 322 to move only within an allowed range, reducing the risk of breakage and providing convenience in use.

[0155] The fastening portion 420 may be connected to one side of the fastening body 410 and coupled to a side surface of the second connector housing 320. For example, the fastening portion 420 may be formed extending from both sides of the fastening body 410 and may include a structure that surrounds both sides of the second connector housing 320. That is, the fastening portion 420 may be formed along both sides of the frame 321 and coupled to both sides of the frame 321.

[0156] The fastening part 420 may be coupled to a side of the frame 321 through a ring structure. Specifically, one side of the fastening part 420 may be connected to the fastening body 410, and the ring structure 421 may be formed at the other end of the fastening part 420. The ring structure 421 of the fastening part 420 may be formed along the side of the frame 321 and fastened to the bottom of the frame 321.

[0157] More specifically, the fastening part 420 may include an inclined surface inclined toward a side surface of the frame 321, and the side surface of the frame 321 may include an inclined surface formed to correspond to the inclined surface of the fastening part 420. The ring structure 421 of the fastening part 420 may be engaged with the side surface of the frame 321 in a sliding manner in which the inclined surface of the fastening part 420 moves along the inclined surface of the side surface of the frame 321. That is, when the second conducting part 310 is inserted into the frame 321, the fastening housing 400 is fastened in a direction perpendicular to the insertion direction of the second conducting part 310, and as the fastening housing 400 is fastened, the inclined surface of the fastening part 420 moves along the inclined surface of the side surface of the frame 321, so that the ring structure 421 of the fastening part 420 may be coupled to the lower side of the side surface of the frame 321.

[0158] [Theme 5] <Penetration structure of fastening housing 400> Figure 28 is an oblique view of a second conductive part according to one embodiment of the present invention being inserted into a second connector housing, Figure 29 is an oblique view of a fastening housing according to one embodiment of the present invention being fastened to the second connector housing and the second conductive part, and Figure 30 is a cross-sectional view of a connector module according to one embodiment of the present invention.

[0159] 28 to 30, the fastening housing 400 may penetrate the second connector housing 320 and the second conducting part 310 to fasten the second connector housing 320 and the second conducting part 310. For example, the fastening housing 400 may further include a fastening pin 430 that protrudes from the fastening body 410 and penetrates the second connector housing 320 and the second conducting part 310. That is, the fastening pin 430 may protrude from the lower surface of the fastening body 410 toward the second conducting part 310. The fastening pins 430 may be formed in pairs on both sides of the lower surface of the fastening body 410.

[0160] Specifically, the fastening body 410 may protrude toward the second conducting part 310 to form a portion that contacts the second conducting part 310. In addition, the fastening body 410 may protrude toward the second conducting part 310 to form a portion that contacts the conductive film 311. The fastening pin 430 may protrude from a portion that protrudes downward from the fastening body 410. That is, the lower surfaces of the first fastening body 411 and the second fastening body 412 may form the same surface. Due to the ring structure of the fastening part 420, the lower surfaces of the first fastening body 411 and the second fastening body 412 protrude further toward the second conducting part 310 than the lower surface of the fastening part 420, and the fastening pin 430 may protrude from the lower surfaces of the first fastening body 411 and the second fastening body 412.

[0161] The end of the fastening pin 430 may have at least one of a curved shape and a horn shape. Such a structure of the end of the fastening pin 430 may increase ease of manufacture in the process of coupling the fastening pin 430 to the second connector housing 320.

[0162] The second connector housing 320 may include a first fastening hole 321a formed therethrough. For example, the first fastening hole 321a may be formed on an inner lower surface of the frame 321. Specifically, the second conducting part 310 is inserted into and coupled to a recessed portion 320-1 surrounded by the frame 321 and the binding part 322. The inner lower surface of the frame 321 is located on the opposite side of the binding part 322 with respect to the recessed portion 320-1, and the first fastening hole 321a may be formed through the inner lower surface of the frame 321. That is, the first fastening hole 321a may be formed to penetrate from the inner lower surface of the frame 321 to the lower surface of the frame 321.

[0163] The second conducting part 310 may include a second fastening hole 310a formed therethrough. That is, the second fastening hole 310a may be formed penetrating from the top surface to the bottom surface of the second conducting part 310. In this case, when the second conducting part 310 is inserted and coupled to the second connector housing 320, the first fastening hole 321a and the second fastening hole 310a may be formed on the same line. In addition, when the second conducting part 310 is inserted and coupled to the second connector housing 320, the fastening pin 430 may be disposed to integrally penetrate the first fastening hole 321a and the second fastening hole 310a.

[0164] The direction in which the second conducting part 310 is inserted into the second connector housing 320 and the direction in which the fastening pin 430 penetrates may be perpendicular to each other.

[0165] With this structure, the fastening pin 430 can restrict the second conducting part 310 from being detached from the second connector housing 320. Specifically, the fastening pin 430 can fix the second conducting part 310 to the second connector housing 320 so as to restrict movement of the second conducting part 310 in a direction parallel to the direction in which the second conducting part 310 is inserted into the second connector housing 320.

[0166] The fastening pin 430 is arranged to pass through the first fastening port 321a and the second fastening port 310a, and the fastening portion 420 is connected to both sides of the frame 321 by a ring structure, thereby further increasing the connecting force between the second connector housing 320 and the second conducting portion 310.

[0167] As a result, the fastening force between the second connector housing 320 and the second conducting part 310 via the fastening pin 430 is increased, and the structural stability of the connector module 100 can be improved.

[0168] Furthermore, this structure of the fastening pin 430 allows the contact area between the first conductive part 210 and the second conductive part 310 to be maintained constant. That is, by fixing the second conductive part 310 at a predetermined position inside the second connector housing 320, the first conductive part 210 and the second conductive part 310 always form a contact area in a constant area, allowing the pre-planned contact method and circuit layout to be maintained, thereby improving the quality of transmission and reception of electrical signals. As a result, this structure allows electrical signals to be transmitted and received more precisely via the connector module 100, and the control quality of the control unit 10 can be further improved.

[0169] [Theme 6] <Tilt prevention structure> The frame 321 may include a structure for preventing tilt of the second connector 300. The tilt refers to a phenomenon in which the appearance and angle of the second connector 300 changes when the second connector 300 is coupled to the first connector 200. This tilt occurs due to a weakening of the coupling force between the first connector 200 and the second connector 300, causing problems that impair the structural stability of the connector module 100, such as the second connector 300 floating or detaching from the first connector 200.

[0170] The tilt phenomenon of the second connector 300 may occur due to the rotational motion of the second connector 300, such as rolling, yawing, and pitching about each axis. Specifically, referring to FIG. 24, there may be a rolling motion that rotates about the x-axis, a pitching motion that rotates about the y-axis, and a yawing motion that rotates about the z-axis. In this case, the x-axis may be formed in a direction parallel to the insertion direction of the second connector 300. The y-axis may be formed in a direction perpendicular to the x-axis and parallel to the ground. The z-axis may be formed in a direction perpendicular to the x-axis and y-axis and perpendicular to the ground.

[0171] A structure for preventing such rotational movement and increasing the coupling stability of the second connector 300 may be necessary.

[0172] FIG. 31 is an internal close-up view of a connector module according to one embodiment of the present invention.

[0173] 25 and 31, the frame 321 includes a frame 321 body and may include at least one of a first protruding portion 321-1 and a second protruding portion 321-2 protruding from one side of the frame 321 body.

[0174] The first protruding portion 321-1 may be formed to protrude forward from the main body of the frame 321 based on the direction in which the second connector 300 is inserted. That is, the first protruding portion 321-1 may extend from the main body of the frame 321 in the x-axis direction (see FIG. 24) and be inserted into the first connector 200. For example, the first connector 200 may further include a second recessed portion 220b recessed forward of the first recessed portion 220a, and the first protruding portion 321-1 may be inserted into the second recessed portion 220b.

[0175] The second recessed portion 220b may be a portion recessed from the first recessed portion 220a toward the x-axis direction inside the first connector housing 220. In this case, when the second connector 300 is viewed from the side with respect to the direction in which the second connector 300 is inserted, the height of the first recessed portion 220a may be greater than the height of the second recessed portion 220b. That is, when the height of the first recessed portion 220a is E1 and the height of the second recessed portion 220b is E2, the condition E1 > E2 may be satisfied. Correspondingly, the height of the first protruding portion 321-1 may be formed to protrude from the main body of the frame 321 so as to be smaller than the height of the main body of the frame 321 when viewed from the side.

[0176] Furthermore, when the second connector 300 is viewed from the side with reference to the direction in which the second connector 300 is inserted, the second recessed portion 220b can form a first surface 220b-1 extending from the inner upper surface of the first recessed portion 220a, a second surface 220b-2 connected to the first surface 220b-1 on one side and forming the front surface, and a third surface 220b-3 connected to the other side of the second surface 220b-2 and forming the bottom surface.

[0177] The first surface 220b-1 may be the upper surface of the second recessed portion 220b. The second surface 220b-2 may be the innermost surface, i.e., the front surface, of the second recessed portion 220b. The second surface 220b-2 may be perpendicular to the first surface 220b-1. The third surface 220b-3 may constitute the lower surface of the second recessed portion 220b and may be perpendicular to the second surface 220b-2. That is, the first surface 220b-1, the second surface 220b-2, and the third surface 220b-3 may be formed along the outer surface of the first protruding portion 321-1.

[0178] The first recessed portion 220a may include a support surface 220a-1 connected to the third surface 220b-3 and extending downward from the third surface 220b-3. That is, the support surface 220a-1 may be formed on the underside of the first protruding portion 321-1.

[0179] The first surface 220b-1 can support the upper surface of the first protruding portion 321-1. The second surface 220b-2 can support the front surface of the first protruding portion 321-1. The third surface 220b-3 can support the lower surface of the first protruding portion 321-1. The support surface 220a-1 can support the front surface of the frame 321, i.e., the front surface of the frame 321 main body.

[0180] According to this structure, the first protrusion 321-1 is engaged with the second recess 220b, thereby restricting the rotational movement of the second connector 300. Specifically, the pitching movement of the second connector 300 about the y-axis may be restricted.

[0181] To maximize pitching prevention, each surface of the first recessed portion 220a and the second recessed portion 220b may satisfy certain conditional expressions. For example, the length F1 of the support surface 220a-1 of the first recessed portion 220a may be 0.4 mm to 0.6 mm. If the length F1 of the support surface 220a-1 of the first recessed portion 220a is less than 0.4 mm, the contact area between the support surface 220a-1 and the front surface of the frame 321 becomes significantly smaller, reducing the support area required for pitching prevention and preventing pitching of the second connector 300. Conversely, if the length F1 of the support surface 220a-1 of the first recessed portion 220a exceeds 0.6 mm, the unnecessary current-carrying area may increase, potentially creating a current-carrying region not intended in the design.

[0182] Furthermore, the length F2 of the second surface 220b-2 of the second recessed portion may satisfy a specific conditional expression. For example, the length F2 of the second surface 220b-2 may be 0.9 mm to 1.1 mm. If the length F2 of the second surface 220b-2 is less than 0.9 mm, the recess depth of the second recessed portion 220b may be small, which may reduce the tilt prevention effect. Conversely, if the length F2 of the second surface 220b-2 exceeds 1.1 mm, the length becomes longer than the thickness of the first protruding portion 321-1, which may cause a problem of damage to the first protruding portion 321-1 due to the tilt phenomenon.

[0183] Furthermore, the first protrusions 321-1 may be formed in directions extending on both sides of the insertion direction of the second connector 300. That is, the first protrusions 321-1 may be formed in a direction parallel to the y-axis direction. With this structure, the shape of the first protrusions 321-1 may prevent the second connector 300 from rolling when the second connector 300 is inserted and coupled to the first connector 200.

[0184] The second protruding portion 321-2 may be formed to protrude upward or downward from the main body of the frame 321 based on the insertion direction of the second connector 300. For example, the second protruding portion 321-2 may be formed to protrude from the lower surface of the main body of the frame 321 in a direction toward the second conducting part 310. Specifically, the second protruding portion 321-2 may be formed to protrude downward in parallel with the z-axis direction.

[0185] 9, when viewed in the direction in which the second connector 300 is inserted, the first connector 200 further includes a third recessed portion 220c recessed above or below the first recessed portion 220a, and the second protruding portion 321-2 may be inserted into the third recessed portion 220c. That is, the third recessed portion 220c may be formed to extend from the first recessed portion 220a along the z-axis direction.

[0186] When viewed from the direction in which the second connector 300 is inserted, i.e., the x-axis direction, the third recessed portion 220c may be formed on both sides of the first recessed portion 220a. Similarly, the second protruding portions 321-2 may be formed on both sides of the frame 321 to correspond to the third recessed portion 220c.

[0187] Furthermore, the third recessed portions 220c formed on both sides of the lower side of the first recessed portion 220a may have a sloping, stepped structure, i.e., the outermost inner surface of the third recessed portion may have a step with respect to the inner surface of the first recessed portion 220a when viewed in the x-axis direction, and may have a sloping structure.

[0188] According to this structure, the second protruding portion 321-2 is inserted into and engaged with the third recessed portion 220c, thereby restricting rotation of the second connector 300. Specifically, the engagement of the second protruding portion 321-2 can prevent yawing of the second connector 300. To maximize this effect, the second protruding portion 321-2 can extend in a longitudinal direction parallel to the direction in which the second connector 300 is inserted.

[0189] [Theme 7] <Structure for Improving Fixing Force of First Conductive Part 210 and Second Conductive Part 310> FIG. 32 is an internal cross-sectional view of a connector module according to one embodiment of the present invention.

[0190] 32, the first conductive part 210 may be electrically connected to only a single surface of the second conductive part 310. That is, the first conductive part 210 does not have a structure that envelops the second conductive part 310, but may only contact one surface of the second conductive part 310. For example, the first conductive part 210 may be electrically connected to the second conductive part 310 by contacting the lower surface of the second conductive part 310 while being disposed through the first connector housing 220.

[0191] 25 and 28, the second connector 300 is inserted into a recessed portion surrounded by the frame 321 and the binding portion 322, and the inner lower surface of the frame 321 is located on the opposite side of the binding portion 322 based on the recessed portion, and the inner lower surface of the frame 321 may support the lower surface of the second conducting portion 310. Here, referring to FIG. 13a, a plurality of holes 350-1 may be formed through the inner lower surface. That is, the plurality of holes 350-1 are formed through the spaces between the comb-shaped structures 350, and the first conducting portion 210 may contact the lower surface of the second conducting portion 310 through the through-formed holes 350-1.

[0192] According to this structure, the first conductive part 210 contacts and is electrically connected to only one side of the second conductive part 310, rather than both sides of the second conductive part 310, thereby reducing the height of the combined structure of the first conductive part 210 and the second conductive part 310, and thereby reducing the overall height of the connector module 100. However, a problem of weakened contact force between the first conductive part 210 and the second conductive part 310 may occur, and the connector module 100 may include a structure to prevent this problem.

[0193] The binding part 322 contacts the upper surface of the second conducting part 310 and applies pressure to the upper surface of the second conducting part 310, thereby strengthening the contact force between the first conducting part 210 and the second conducting part 310. For example, the front of the binding part 322 is fixedly connected to the upper surface of the frame 321, while the rear of the binding part 322 is movable upward or downward. Here, the front of the binding part 322 connected to the upper surface of the frame 321 may include a ring structure that forms an empty space inside. That is, the binding part 322 includes an elastic material, and the ring structure allows the rear of the binding part 322 to undergo elastic deformation, moving upward or downward.

[0194] Specifically, the binding portion 322 may include a contact portion 322-2 that contacts an upper surface of the second conducting portion 310. The binding portion 322 may also include a binding portion 322-3 that binds to the first connector 200. The front of the binding portion is connected to the front of the contact portion 322-2, and the binding portion 322-3 extends rearward based on the insertion direction of the second connector 300, and a portion of the binding portion 322-3 may be spaced apart from the contact portion 322-2 by a predetermined distance. The binding portion 322-3 may be coupled to or disengaged from a hole 230 formed through the upper surface of the first connector housing 220, thereby allowing the second connector 300 to be coupled to or uncoupled from the first connector 200.

[0195] More specifically, with contact portion 322-2 in contact with the upper surface of second conducting portion 310 and the front of binding portion 322 fixed, an external force is applied to the rear upper surface of binding portion 322-3 using the principle of leverage, causing the rear of binding portion 322-3 to move downward and become closer to contact portion 322-2. During this process, after second connector 300 is inserted into first connector 200, binding portion 322-3 also moves upward, and a portion of the upper surface of binding portion 322-3 protrudes and fits into hole 230 formed through the upper surface of first connector housing 220, thereby binding second connector 300 to first connector 200. The process of releasing the binding between first connector 200 and second connector 300 can be performed by performing the reverse operation. As a result, with such a structure of the binding part 322, the second conductive part 310 can be more firmly fixed by fitting between the contact portion 322-2 and the first conductive part 210.

[0196] Furthermore, in order to further enhance the fixing effect, each part of the binding part 322 can satisfy a specific conditional expression.

[0197] For example, when viewed from the side with respect to the direction in which the second connector 300 is inserted and coupled, the height G1 of the contact portion 322-2 may be 0.6 mm to 1.5 mm. If the height G1 of the contact portion 322-2 is less than 0.6 mm, the thickness of the contact portion 322-2 becomes too small, reducing the pressure with which the contact portion 322-2 supports the second conducting part 310. This may result in a loss of the function of the contact portion 322-2 to support the second conducting part 310 and strengthen the fixing force between the first conducting part 210 and the second conducting part 310. Conversely, if the height G1 of the contact portion 322-2 exceeds 1.5 mm, the thickness of the binding part 322 itself may become too large, increasing the overall height of the connector module 100. Also, the separation distance between the contact portion 322-2 and the binding part 322-3 may become too small, preventing the binding part 322 from functioning smoothly.

[0198] Furthermore, the length G2 of the contact portion 322-2, which is formed along the direction in which the second connector 300 is inserted and coupled and which contacts the second conducting part 310, may be 1.8 mm to 2.1 mm. If the length G2 of the contact portion 322-2 which contacts the second conducting part 310 is less than 1.8 mm, the contact force between the contact portion 322-2 and the second conducting part 310 may be weakened, and the function of the contact portion 322-2 to strengthen the fixing force between the first conducting part 210 and the second conducting part 310 may be lost. Conversely, if the length G2 of the contact portion 322-2 which contacts the second conducting part 310 exceeds 2.1 mm, the separation space between the binding part 322 and the second conducting part 310 may be excessively damaged, and the function of the binding part 322 may be reduced.

[0199] Furthermore, the separation distance G3 between the contact portion 322-2 and the binding portion 322-3 may be 0.23 mm to 0.27 mm. If the separation distance G3 between the contact portion 322-2 and the binding portion 322-3 is 0.23 mm or less, the functionality of the binding portion 322 may be reduced. Conversely, if the separation distance G3 between the contact portion 322-2 and the binding portion 322-3 is more than 0.27 mm, the thickness of the contact portion 322-2 and the binding portion 322-3 may be too thin, which may result in the contact portion 322-2 and the binding portion 322-3 being easily damaged by external factors.

[0200] When viewed from the side with respect to the direction in which the second connector 300 is inserted and coupled, the binding portion 322 satisfies the condition 2.5≦G2 / G1≦3.5. If G2 / G1<2.5, the contact force between the contact portion 322-2 and the second conducting portion 310 is weakened, and the function of the contact portion 322-2 to strengthen the fixing force between the first conducting portion 210 and the second conducting portion 310 may be lost. Conversely, if G2 / G1>3.5, the length increases relative to the thickness, and the strength of the contact portion 322-2 may be weakened, resulting in a problem of easy breakage.

[0201] 31 , when the length from the frontmost surface of the binding portion 322 to the rearmost surface is G5 and the length from the frontmost surface of the binding portion 322 to the rearmost surface of the contact portion 322-2 is G4, the conditional expression 2≦G5 / G4≦2.5 can be satisfied. If G5 / G4 is less than 2, the area over which the underside of the contact portion 322-2 supports the second conducting portion 310 becomes small, preventing this principle from being fully applied to the binding portion 322-3, which may result in reduced functionality of the binding portion 322. Conversely, if G5 / G4 exceeds 2.5, the binding portion 322 may occupy excessive space within the connector module 300, or the binding portion 322-3 may be engaged with the contact portion 322-2, preventing an appropriate separation distance between the binding portion 322-3 and the second conducting portion 310, resulting in reduced binding functionality.

[0202] 31 , the rear lower surface of the binding portion 322-3 may include an inclined surface 322-3a so that the binding portion 322-3 can be effectively moved downward to bind or release from the first connector housing 220. Specifically, the inclined surface 322-3a may be formed on the rear lower surface of the binding portion 322-3 so that the distance between the binding portion 322-3 and the second conductive part 310 increases as the binding portion 322-3 approaches the rearmost part of the binding portion 322-3. For example, the inclination angle θ of the inclined surface 322-3a with respect to an extension line of the front lower surface of the binding portion 322-3 may be 5 to 8 degrees. If the inclination angle θ of the inclined surface 322-3a is less than 5 degrees, the distance between the rearmost lower surface of the binding portion 322-3 and the second conductive part 310 may not be adequately secured, which may reduce the binding function of the binding portion 322. Conversely, if the inclination angle θ of the inclined surface 322-3a exceeds 8 degrees, the thickness of the binding portion 322-3 becomes too thin, which may cause a problem of easy breakage and deformation due to external impact.

[0203] In this case, the distance G6 between the rearmost end of the binding portion 322 and the second conducting portion may be 0.7 to 0.8 mm so that the binding portion 322 is spaced apart from the second conducting portion to more effectively perform the binding function. In order to increase the fixing force and contact force between the first conducting portion 210 and the second conducting portion 310, the fastening housing 400 may further fasten the second conducting portion 310 to the second connector housing 320 by a fastening structure. The fastening housing 400 may include a fastening body 410 and a fastening portion 420.

[0204] The fastening portion 420 may be connected to one side of the fastening body 410 and coupled to a side surface of the second connector housing 320. For example, the fastening portion 420 may be formed extending from both sides of the fastening body 410 and may include a structure that surrounds both sides of the second connector housing 320. That is, the fastening portion 420 may be formed along both sides of the frame 321 and coupled to both sides of the frame 321.

[0205] The fastening part 420 may be coupled to a side of the frame 321 through a ring structure 421. Specifically, one side of the fastening part 420 may be connected to the fastening body 410, and the ring structure 421 may be formed at the other end of the fastening part 420. The ring structure 421 of the fastening part 420 may be formed along the side of the frame 321 and may be fastened to the bottom of the frame 321.

[0206] More specifically, the fastening part 420 may include an inclined surface inclined toward a side surface of the frame 321, and the side surface of the frame 321 may include an inclined surface formed to correspond to the inclined surface of the fastening part 420. The ring structure of the fastening part 420 may be engaged with the side surface of the frame 321 in a sliding manner in which the inclined surface of the fastening part 420 moves along the inclined surface of the side surface of the frame 321. That is, when the second conducting part 310 is inserted into the frame 321, the fastening housing 400 is fastened in a direction perpendicular to the insertion direction of the second conducting part 310, and as the fastening housing 400 is fastened, the inclined surface of the fastening part 420 moves along the inclined surface of the side surface of the frame 321, so that the ring structure 421 of the fastening part 420 may be coupled to the lower side of the side surface of the frame 321.

[0207] As a result, the first conducting part 210 contacts only a single surface of the second conducting part 310, and the fixing force between the first conducting part 210 and the second conducting part 310 is strengthened by the binding part 322 and the fastening housing 400, thereby reducing the overall height of the connector module 100 and allowing the connector module 100 to occupy space more effectively within the battery module. Specifically, the height H3 of the connector module 100 may be 3.5 mm to 4 mm. That is, the height of the first connector 200 may be 3.5 mm to 4 mm.

[0225] According to S400, the connector inspection method can include an assembly distance determination step.

[0226] The assembly distance determination step may be a step of determining whether an assembly distance D from the first reference line to the second reference line is within a critical distance range. Critical distance range data, which is used as a criterion for determining whether the assembly distance D is within the critical distance range, may be predefined.

[0227] The assembly distance determination step may include comparing the identified assembly distance D with pre-stored critical distance range data.

[0228] According to S500, the connector inspection method may include a step of determining whether the connector is properly attached.

[0229] The normal mounting possibility determining step may be a step of determining that the assembly has been performed normally when it is determined that the assembly distance D is within a predetermined distance range.

[0230] The connector inspection method may further include a notification providing step.

[0231] The notification providing step may be a step of providing a notification of information regarding normal or abnormal mounting to the user via a user interface after the normal mounting determination step.

[0232] According to the above-described connector inspection method, it is possible to determine whether a connector is properly installed. As a result, it is possible to quickly and error-freely determine whether a connector or connector module is properly installed during an automated assembly (or installation) process through vision inspection.
