[0016] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that they can be easily implemented by a person with ordinary skill in the art to which the present invention pertains. However, the present invention can be realized in a variety of different forms and is not limited or restricted by the embodiments described below.

[0017] For the purpose of clearly describing the present invention, detailed descriptions of relevant prior art that are irrelevant to the description or that could obscure the gist of the invention have been omitted. In this specification, when assigning reference numerals to components in the drawings, the same or similar reference numerals are used for components that are the same or similar throughout the specification.

[0018] Furthermore, the terms and words used in this specification and in the claims should not be interpreted in a manner limited to their ordinary or dictionary meanings, but rather should be interpreted in a manner consistent with the technical idea of ​​the present invention, in accordance with the principle that inventors may define the concepts of terms as appropriate to best describe their invention.

[0019] [Theme 1] Figure 1 is a perspective view showing a battery module 1 according to one embodiment of the present invention; Figure 2 is a plan view showing the battery module 1 according to one embodiment of the present invention viewed from above; Figure 3 is a perspective view showing the battery module 1 according to one embodiment of the present invention with the upper case omitted; and Figure 4 is a magnified partial view showing the battery module 1 according to one embodiment of the present invention with the connector module 100 attached to the control unit 10.

[0020] <Structure of Battery Module 1> Referring to Figure 1, the battery module 1 may contain multiple batteries (e.g., multiple batteries 2 in Figure 3). For example, the multiple batteries 2 may be rechargeable batteries that can be repeatedly charged and discharged. The multiple batteries 2 may be arranged regularly in a predetermined pattern, but are not limited to this. The multiple batteries 2 may be electrically connected to the outside of the battery module 1.

[0021] The battery module 1 may include a battery case 3. For example, the battery case 3 may be provided to enclose multiple batteries 2. The battery case 2 may form part of the outer edge of the battery module 1.

[0022] 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 can form the upper part of the battery module 1 while covering the top of multiple batteries 2. The side case 3-2 can form the side of the battery module 1 while covering the sides of multiple batteries 2. The lower case 3-3 can form the lower part of the battery module 1 while covering the bottom of multiple batteries 2.

[0023] At least two of the upper case 3-1, side case 3-2, and lower case 3-3 can be formed as a single unit.

[0024] For example, if the upper case 3-1 and the lower case 3-3 are formed as a single unit, multiple 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.

[0025] For example, if the upper case 3-1 and the side case 3-2 are formed as a single unit, multiple batteries 2 can be placed inside the battery case 3 from which the lower case 3-3 has been removed, and then the lower case 3-3 can be assembled.

[0026] The battery module 1 may include a control unit 10. For example, the control unit 10 may be mounted in the battery case 3. Specifically, for example, the control unit 10 may be mounted in the upper case 3-1. The control unit 10 may be configured to communicate wirelessly with an external control device.

[0027] The battery module 1 may include a connector module 100 (see Figure 3). For example, the connector module 100 can electrically connect the control unit 10 to multiple batteries 2. Furthermore, the connector module 100 can be attached to and detached from the control unit 10.

[0028] The control unit 10 may include a control PCB 11. For example, the control PCB 11 can be electrically connected to multiple batteries 2 via a connector module 100. The control PCB 11 can be configured to communicate wirelessly with an external control device. The control PCB 11 can be mounted in the battery case 3 (or upper case 3-1). Mounting it on top may be advantageous for wireless communication.

[0029] The control PCB 11 may be mounted on a PCB frame 13. For example, the PCB frame 13 can be a frame for mounting the control PCB 11. The control PCB 11 can be mounted on the upper case 3-1 via the PCB frame 13. More specifically, the control PCB 11 can be mounted on the PCB frame 13, and the PCB frame 13 can be mounted on the upper case 3-1. Alternatively, the PCB frame 13 can be placed in a PCB mounting area formed in a recess or indentation in the upper case 3-1. In this case, the PCB frame 13 can be visible from the outside when the control unit cover 12 is not mounted. However, it is not limited to this.

[0030] The control unit 10 may include a control unit cover 12. For example, the control unit cover 12 can cover the control PCB 11. The control unit cover 12 can be attached to the battery case 3 (or upper case 3-1). By covering the top of the control PCB 11, the control unit cover 12 can protect the control PCB 11 from external impacts to the control unit 10.

[0031] Referring to Figure 2, the control unit 10 can be installed in the upper case 3-1 of the battery case 3. The area of ​​the region where the control unit 10 is installed can 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 mm², the area of ​​the region where the control unit 10 is installed can be 22,752 mm². In this case, the area of ​​the region where the control unit 10 is installed can be approximately 18% of the area of ​​the upper case 3-1. However, the above figures are examples and are not necessarily limiting. By forming the area of ​​the region where the control unit 10 is installed to be 20% or less of the area of ​​the upper case 3-1, the limited space can be effectively utilized.

[0032] Referring to Figures 3 and 4, the connector module 100 can be mounted on the control PCB 11. For example, the connector module 100 can be mounted on the control PCB 11. The connector module 100 can 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, it is not limited to this.

[0033] The connector module 100 may include multiple 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 can be connected to the first electrodes of multiple 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 can be connected to the second electrodes of multiple batteries 2 having a different polarity from the first electrodes. By including multiple connector modules 101, 102 in the connector module 100, electrodes of multiple batteries 2 having different polarities can be effectively connected. However, without limitation, the connector module 100 may also be formed as a single module. For example, a single connector module 100 may extend toward the other side of the battery case 3 and be connected to electrodes of multiple batteries 2 having different polarities.

[0034] The first connector module 101 and the second connector module 102 can be positioned at a distance from each other. For example, although each of the first connector module 101 and the second connector module 102 is mounted on the control PCB 11, they can be positioned at a predetermined distance apart. The predetermined distance at which the first connector module 101 and the second connector module 102 are positioned is not particularly limited. To further explain, the range in which the first connector module 101 and the second connector module 102 can be mounted on the control PCB 11 can be a range in which the first connector module 101 and the second connector module 102 do not overlap to prevent misassembly. However, the above numerical range is illustrative and not limited thereto.

[0035] The first connector module 101 and the second connector module 102 can each extend in opposite directions. For example, each of the first connector module 101 and the second connector module 102 may include a conduction section, each of which can be connected to electrodes having opposite polarities. Each of the said conduction sections may correspond to a second conduction section 310, which will be described later. By arranging the first connector module 101 and the second connector module 102 at a distance from each other, the length of the conduction section (e.g., the second conduction section 310) extending for electrical connection can be effectively reduced in proportion to the degree of separation. As described above, the conduction section is described as being included in the connector module, but the conduction section is an FFC connected to the connector module and may be described and understood as a different configuration.

[0036] The connector module 100 may include a first connector 200 and a second connector 300. For example, the first connector 200 may be mounted (or coupled) to a control unit 10 (or control PCB 11) so as to be electrically connected. The second connector 300 may be mounted 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. If the connector module 100 includes a plurality of connector modules 101, 102, each of the plurality of connector modules 101, 102 may include a first connector 200 and a second connector 300.

[0037] Figure 5 is an exploded perspective view showing a connector module 100 according to one embodiment of the present invention. The above-described embodiments can be applied identically or similarly to this embodiment.

[0038] <Structure of connector module 100> The connector module 100 can be formed by attaching a second connector 300 to a first connector 200. By attaching the second connector 300 to the first connector 200, the control PCB 11 and multiple batteries 2 can be electrically connected.

[0039] Referring to Figure 5, the first connector 200 may include a first conduction section 210. For example, the first conduction section 210 can be electrically connected to the control unit 10. More specifically, the first conduction section 210 can be electrically connected to the control PCB 11.

[0040] The first connector 200 may include a first connector housing 220. For example, the first connector housing 220 may form the outer edge of the first connector 200. An insertion space V into which the second connector 300 can be inserted may be formed inside the first connector housing 220 (see Figure 18, etc.).

[0041] A hole 230 can be formed in the first connector 200. For example, a part of the second connector 300 (or as described later) can be formed in the first connector housing 220. joint part A hole 230 can be formed so that 322) can be hooked into place. Multiple holes 230 can be formed.

[0042] The second connector 300 may include a second conduction section 310. For example, the second conduction section 310 may extend to a predetermined length to be electrically connected to a plurality of batteries 2. The second conduction section 310 may include folded portions during extension. In another example, the second conduction section 310 may be an FFC (flat flexible cable).

[0043] As stated above, the second conduction section 310 is described as being included in the second connector 300, but the second conduction section 310 is an FFCC connected to the second connector 300 and may be described and understood as a separate configuration.

[0044] The second connector 300 may include a conductive film 311. For example, the conductive film 311 can be placed on the second conductive portion 310. Specifically, the conductive film 311 can be placed between the second conductive portion 310 and the second connector housing 320.

[0045] As stated above, the conductive film 311 is described as being included in the second connector 300, but the conductive film 311 may also be described and understood as a separate component.

[0046] The second connector 300 may include a second connector housing 320. For example, the second connector housing 320 may form the 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.

[0047] The second connector 300 is joint partIt can contain 322. joint part 322 can be provided in the second connector housing 320 so as to be rotatable to a predetermined degree. For example, joint part During the process of being inserted into the first connector 200, 322 can rotate in a direction closer to or further away from the second connector housing 320 as a reference. Further explanation: joint part 322 is inserted into the first connector 200 during the process, joint part It can be rotated to include a section where a difference in height occurs at the end of 322. joint part 322 (or joint part The end of 322 passes through the hole 230 of the first connector 200 into the first connector housing 220. join By doing so, the first connector 200 and the second connector 300 join It can be made to happen.

[0048] The connector module 100 may include a fastening housing 400. The fastening housing 400 can restrict the movement of the second conduction part 310 relative to the second connector housing 320. By restricting the movement of the second conduction part 310, the fastening housing 400 can stably maintain electrical contact between the first conduction part 210 and the second conduction part 310.

[0049] Figure 6 is a longitudinal cross-sectional view showing a connector module 100 attached to a control unit 10 according to one embodiment of the present invention, and Figure 7 is a longitudinal cross-sectional view showing a control unit cover 12 according to one embodiment of the present invention. The above description of the embodiments can be applied to this embodiment in the same or similar manner. The following description will be made with reference to Figures 6 and 7.

[0050] <Structure of control unit 10> The control PCB 11 can be placed on a PCB frame 13 which is positioned in a PCB mounting area formed in a recess or indentation in the upper case 3-1. The control PCB 11 may include an area where the connector module 100 is placed and an area where the connector module 100 is not placed. The area where the connector module 100 is not placed may be the area of ​​the control PCB 11 other than the area where the connector module 100 is placed.

[0051] The control unit cover 12 can define a housing space in which the connector module 100 is housed. For example, the control unit cover 12 can define a housing space for the connector module 100 by being positioned to cover the control PCB 11 on the battery case 3 (or upper case 3-1). In another example, the control unit cover 12 can cover the top of the connector module 100 by being mounted on the battery case 3 (or upper case 3-1).

[0052] In areas where the connector module 100 is not located, the height H1 from the control PCB 11 to the control unit cover 12 can be less than 4 mm (e.g., 3.92 mm).

[0053] The control unit cover 12 may include a cover recess 12-1. The cover recess 12-1 can be formed by recessing the area of ​​the control unit cover 12 facing the connector module 100 to a predetermined degree. Specifically, for example, in the area where the connector module 100 is located, the height from the control PCB 11 to the control unit cover 12 (or the height H2 of the cover recess 12-1) can be 5 mm or less.

[0054] The area of ​​the cover recess 12-1 facing the connector module 100 may include a curved area. For example, by forming a gently sloping area in the area facing the connector module 100, damage to the connector module 100 and the control unit cover 12 can be minimized in the event of collision or contact with the connector module 100.

[0055] The predetermined degree (or height) H4 of the recessed portion 12-1 of the cover can be 2 / 3 or more of the thickness of the remaining non-recessed portion. For example, the thickness of the cover recessed portion 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.

[0056] The thickness of the cover recess 12-1 can 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 can be 0.5 mm, and the thickness of the remaining portion can be 1.5 mm.

[0057] In this case, the predetermined degree of recession (H4) can be 1 mm.

[0058] The height H3 of the connector module 100 can be less than the height H2 of the cover recess 12-1. For example, when the height H2 of the cover recess 12-1 is formed to be 5 mm or less, the height of the connector module 100 can be formed to be 4 mm or less. Specifically, for example, if the height H2 of the cover recess 12-1 is 4.92 mm, the height H3 of the connector module 100 can be 3.9 mm. However, the above numerical ranges are illustrative and not limiting.

[0059] The distance from the control PCB 11 to the control unit cover 12 can be within the range of 3.9 mm to 5 mm. For example, the distance from any area of ​​the control PCB 11 to the control unit cover 12 can be within the range of 3.9 mm to 5 mm. Specifically, for example, in the area of ​​the control PCB 11 where the connector module 100 is placed, the distance from the control PCB 11 to the control unit cover 12 can be 4.92 mm. Also, in the remaining area of ​​the control PCB 11, the distance from the control PCB 11 to the control unit cover 12 can be 3.92 mm. However, the above numerical range is an example with an error range of 0.05 mm and is not limited thereto.

[0060] As described above, by providing the cover recess 12-1 in the control unit cover 12, it is possible to prevent the connector module 100 from increasing the height of the control unit cover 12 itself, thereby effectively miniaturizing it. 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.

[0061] Figure 8 is a perspective view showing the arrangement of the second conduction unit 310 according to one embodiment of the present invention. The above description of the embodiment can be applied identically or similarly to this embodiment.

[0062] <Structure of the second conduction section 310> The second connector 300 may include a second conduction section 310. Although the second conduction section 310 is described as being included in the second connector 300, the second conduction section 310 is an FFC connected to the second connector 300 and may be described and understood as a separate configuration.

[0063] The second conduction section 310 can be electrically connected to multiple batteries 2. For example, the second conduction section 310 can extend to a predetermined length so as to be electrically connected to multiple batteries 2. The predetermined length can be such that it extends from the second connector housing 320 to one side (or another side) of the battery case 3 and is electrically connected to multiple batteries 2.

[0064] The second conduction section 310 may include folded portions 312 and 313 during extension. For example, the second conduction section 310 may include a first folding portion 312 and a second folding portion 313 during extension. Specifically, the second conduction section 310 can be an FFC, which can maintain electrical connectivity even when folded. This allows for maximizing spatial efficiency by folding the second conduction section 310 during extension, enabling effective connection to multiple batteries 2. Furthermore, by structurally adaptively designing and implementing the folding of the second conduction section 310 through various paths, electrical connectivity paths can be effectively realized.

[0065] An FFC (flexible flat cable) is connected as a cable (e.g., a strip-shaped cable) via a connector housing, while an FPC (flexible printed circuit) is a printed circuit. An FFC can be taller than an FPC. However, according to the above embodiment, the connector module 100 is formed with a height of 4 mm or less to maximize spatial efficiency.

[0066] [Theme 2] Figure 9 is a perspective view showing the first connector 200 according to one embodiment of the present invention from one direction, and Figure 10 is a perspective view showing the first connector 200 according to one embodiment of the present invention from another direction. The above description of the embodiments can be applied to this embodiment in the same or similar manner. The following description will be made with reference to Figures 9 and 10.

[0067] <Reinforcement structure of the first connector 200> The first connector 200 may include a raised portion 221. For example, the raised portion 221 may be formed protruding from the inner bottom surface of the first connector housing 220. The first conductive portion 210 may also be mounted on the raised portion 221.

[0068] The raised portion 221 may include a body portion 222. For example, the body portion 222 may protrude from the inner bottom surface of the first connector housing 220 by a first height h1. Specifically, for example, if 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.

[0069] The raised portion 221 may include a partition wall 223. For example, the partition wall 223 may be formed to protrude from the body portion 222. The partition wall 223 may protrude from the inner bottom surface to a second height h2 that is higher than the first height h1. The partition wall 223 may protrude from the body portion 222 in a plurality of partition wall-like manner. The body portion 222 may be formed to include a region where the partition wall 223 is located when viewed from above, and may extend toward the opening 220-1.

[0070] Multiple first conduction sections 210 can be arranged in a direction that crosses the direction DI into which the second connector 300 is inserted. For example, the first conduction sections 210 can be formed in the form of multiple connecting terminals and arranged in the aforementioned crossing direction. In another example, the first conduction sections 210 can be in a configuration in which multiple connecting terminals are arranged alternately with the partition wall 223. This alternate arrangement can be for preventing short circuits of the connecting terminals.

[0071] The body portion 222 can extend parallel to the direction in which the first conduction portion 210 is positioned. For example, the length w1 of the body portion 222 in the direction across the direction DI into which the second connector 300 is inserted can be in the range of 10 mm to 13 mm. The width w2 of each partition wall 223 can be in the range of 0.5 mm to 0.7 mm. The partition walls 223 can include plastic material (e.g., engineering plastic). For example, the partition wall 223 can be PA9T, but is not limited to this. When the partition wall 223 is formed of the above-mentioned plastic material, it can have high temperature and long-term heat resistance, strong resistance to various chemicals, and can have the general effects of mechanical properties obtained from engineering plastics.

[0072] By forming a raised portion 221 on the first connector 200, which includes a reinforcing body portion 222 and a partition wall 223, it is possible to effectively prevent damage or breakage of the partition wall 223 due to direct collision or interference with the second connector housing 320 when the second connector 300 is inserted. Since the body portion 222 has a structure that fills the lower space of the partition wall 223, the strength of the partition wall can be supplemented, thereby preventing the partition wall from being easily damaged and allowing it to maintain its shape firmly.

[0073] Figure 11 is a perspective view showing a recessed line 224 according to one embodiment of the present invention. The description of the above-described embodiment can be applied identically or similarly to this embodiment.

[0074] <Indented line 224> The body portion 222 may include a recessed line 224. For example, the recessed line 224 can be formed by being recessed in the body portion 222.

[0075] The recessed lines 224 can be formed alternately with the partition walls 223. Specifically, when viewed from the opening 220-1 side, the recessed lines 224 can be formed alternately between the partition walls 223.

[0076] The recessed line 224 can extend away from the partition wall 223 to the opening side 220-1. For example, the recessed line 224 can extend away from the partition wall 223 in a direction parallel to the direction in which the second connector 300 is inserted, and can extend to the opening side 220-1 in a direction parallel to the direction in which the second connector 300 is inserted.

[0077] The recessed line 224 can be provided to guide the comb-shaped structure 350, which will be described later. For example, the recessed line 224 can be in a form corresponding to the comb-shaped structure 350. The recessed line 224 can be formed as a recess in the body portion 222 so that the comb-shaped structure 350 can be guided when inserted.

[0078] The inclusion of a recessed line 224 in the body portion 222 effectively prevents the comb-shaped structure 350 from deviating from the insertion path when the second connector 300 is inserted into the first connector 200, thereby preventing damage or breakage of the partition wall 223 due to direct collision or interference with the second connector housing 320.

[0079] The recessed line 224 can be provided so that a portion of the comb-shaped structure 350 is fitted into it when the comb-shaped structure 350 is inserted into the partition wall 223. For example, when the end of the comb-shaped structure 350 is inserted and fitted between the partition walls 223, the portion of the comb-shaped structure 350 on the comb-shaped base portion 360 side can be fitted into the recessed line 224. By fitting a portion of the comb-shaped structure 350 into the recessed line 224, vibrations caused by vibrations and shocks can be further prevented when the first connector 200 and the second connector 300 are coupled, thereby ensuring that the electrical connection is maintained stably.

[0080] Figure 12 is a perspective view showing the comb-shaped structure 350 of the second connector 300 according to one embodiment of the present invention, Figure 13a is a bottom view showing the comb-shaped structure 350 of the second connector 300 according to one embodiment of the present invention from the bottom, and Figure 13b is a perspective view of the second connector according to one embodiment of the present invention viewed from below.

[0081] The above-described embodiments can be applied identically or similarly to these embodiments. The following description will be made with reference to Figures 12, 13a, and 13b.

[0082] <Open section 340> An open portion 340 may be formed in the second connector 300. For example, the open portion 340 may be a space provided such that the partition wall 223 is located when the first connector 200 and the second connector 300 are connected. Specifically, for example, the open portion 340 may represent the space between the protruding portion 321-2 (described later) and the comb-shaped structure 350. Alternatively, the open portion 340 may represent the space between the comb-shaped structures 350. When the first connector 200 and the second connector 300 are connected, the partition wall 223 may be inserted into the space between the protruding portion 321-2 and the comb-shaped structure 350 or into the space between the comb-shaped structures 350.

[0083] <Comb-shaped structure 350> The second connector 300 may include a comb-shaped base portion 360. For example, the comb-shaped base portion 360 may be the portion that faces the body portion 222 when the second connector 300 is inserted into the first connector 200.

[0084] The second connector 300 may include a comb-shaped structure 350. For example, the comb-shaped structure 350 may protrude from the comb-shaped base portion 360 toward the first connector 200. In another example, the comb-shaped structure 350 may be in a form corresponding to the raised portion 221 of the first connector 200.

[0085] Frames (e.g., frame 321 in Figures 25 and 28) and joint part The second conduction part 310 can be inserted and placed in the recessed portion surrounded by 322. Multiple holes 350-1 are formed through the space between the comb-shaped structures 350, and the first conduction part 210 can come into contact with the lower surface of the second conduction part 310 through the holes 350-1. In this case, the first conduction part 210 can come into contact with one surface of the second conduction part 310 and be electrically connected.

[0086] With respect to 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-shaped structure 350 can be in the range of 1 to 3. For example, with respect to the direction in which the second connector 300 is inserted, the length of the comb-shaped structure 350 can 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 can be in the range of 4 mm to 6 mm. Specifically, if the length of the comb-shaped structure 350 is 2 mm and the length of the inserted portion is 6 mm, the ratio of the length of the comb-shaped structure 350 to the length of the portion of the second connector 300 inserted into the first connector 200 can be 3. Also, if the length of the comb-shaped structure 350 is 4 mm and the length of the inserted portion is 4 mm, the ratio of the length of the comb-shaped structure 350 to the length of the portion of the second connector 300 inserted into the first connector 200 can be 1. However, it is not limited to the above.

[0087] 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 so as to wrap around both sides of the raised portion 221 when the second connector 300 is inserted into the first connector 200. Alternatively, the protruding portions 321-2 may extend from both ends of the second connector housing 320 with respect to the direction in which the second connector 300 is inserted. In another example, the protruding portions 321-2 may protrude from the second connector housing 320 so as to face the inner bottom surface when the second connector 300 is inserted into the first connector 200. By providing the protruding portions 321-2 so as to wrap around the raised portion 221 of the first connector 200, the insertion of the second connector 300 can be guided. Furthermore, by guiding the second connector 300, damage to the partition wall 223 can be prevented, and short circuits at the connecting terminals of the first conduction section 210 can be prevented.

[0088] Figure 14 is a plan view showing the connection of the first connector 200 and the second connector 300 according to one embodiment of the present invention, Figure 15 is a longitudinal cross-sectional view showing the cross-section along the BB line in the connected state of the first connector 200 and the second connector 300 according to one embodiment of the present invention, and Figure 16 is a longitudinal cross-sectional view showing the cross-section along the CC line in the connected state of the first connector 200 and the second connector 300 according to one embodiment of the present invention. The above description of the embodiments can be applied to this embodiment in the same or similar manner. The following description will be made with reference to Figures 14 to 16.

[0089] <Relationship between the raised portion 221, the comb-shaped structure 350, and the comb-shaped base portion 360> The second connector 300 can be inserted and fitted inside the first connector 200. In this case, the second connector 300 joint part 322 can be hooked into the hole 230 of the first connector 200.

[0090] The fastening housing 400 can restrict the movement of the second conduction portion 310. For example, the fastening housing 400 can be mounted on the second connector housing 320 in such a way as to restrict the movement of the second conduction portion 310.

[0091] Referring to the cross section by the BB line, the comb-shaped structure 350 can be inserted between the partition walls 223. For example, the comb-shaped structure 350 can be provided to fit into the space between the partition walls 223 when the second connector 300 is inserted into and mounted on the first connector 200. Alternatively, the comb-shaped structure 350 and the partition walls 223 may have corresponding structures that are insertable and connectable to each other.

[0092] Referring to the cross-section shown by the CC line, the comb-shaped base portion 360 can be aligned with the body portion 222. For example, the comb-shaped base portion 360 can be positioned to face and align with the body portion 222 when the second connector 300 is inserted into and mounted on the first connector 200. Alternatively, the comb-shaped base portion 360 and the body portion 222 can have corresponding structures to align when facing each other.

[0093] [Theme 3] Figure 17 is a plan view showing the first connector 200 according to one embodiment of the present invention as seen from above, and Figure 18 is a longitudinal cross-sectional view showing a cross-section of the first connector 200 according to one embodiment of the present invention. The above description of the embodiments can be applied to this embodiment in the same or similar manner. The following description will be made with reference to Figures 17 and 18.

[0094] <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 a second connector 300 can be inserted.

[0095] The first connector housing 220 can define an insertion space V. For example, the insertion space V can be defined by the upper part 220-2, the side part 220-3, and the lower part 220-4 of the first connector housing 220. More specifically, the insertion space V can be defined by being enclosed by the inner surface of the upper part 220-2, the inner surface of the side part 220-3, and the inner surface of the lower part 220-4.

[0096] A first conduction section 21 can be provided in the lower part 220-4 so as to be electrically connected to the second connector 300.

[0097] The first connector housing 220 can be provided with a hole 230 formed through the upper part 220-2, so that the second connector 300 can be hooked into it.

[0098] The first connector housing 220 may include a protruding rib 225. For example, the protruding rib 225 can be formed on the edge of the upper part 220-2. Specifically, the protruding rib 225 can be formed protruding from the edge of the upper part 220-2 on the side into which the second connector 300 is inserted. The protruding rib 225 can reinforce the structural rigidity of the upper part 220-2 in which the hole 230 is formed.

[0099] Figure 19 is a plan view showing a protruding rib 225 of a first connector 200 according to one embodiment of the present invention. The above description of the embodiment can be applied identically or similarly to this embodiment.

[0100] <Structure of the protruding rib 225> The edge of the upper part 220-2 on the opening 220-1 side may include a protruding rib 225. For example, the upper part 220-2 may include a protruding rib 225 that projects in the direction toward the opening 220-1 from the hole 230.

[0101] 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 3 to 4 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.

[0102] The degree of protrusion A' of the protruding rib 225 can be determined according to the thickness T of the upper part 220-2. For example, the greater the thickness T of the upper part 220-2, the greater the degree of protrusion A' can be.

[0103] By forming a protruding rib 225 on the first connector housing 220, the rigidity of the upper part 220-2 in which the hole 230 is formed can be reinforced. For example, even when an external force is applied, the pressure is distributed in proportion to the degree to which the protruding rib 225 protrudes, thereby preventing the occurrence of cracks or damage to the upper part 220-2.

[0104] 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, the length g in the diagonal direction is also extended, thereby reinforcing the strength in the diagonal direction.

[0105] Figure 20 is a plan view showing a hole 230 of a first connector 200 according to one embodiment of the present invention. The above description of the embodiment can be applied identically or similarly to this embodiment.

[0106] <Structure of Hall 230> A hole 230 can be formed in the first connector housing 220. For example, the hole 230 may include a rounded shape on the edge facing the opening 220-1. The rounded shape formed in the hole 230 can be formed such that the fillet radius value R is 0.3 mm to 1 mm.

[0107] The hole 230 may include multiple holes. For example, the multiple holes may be formed along a direction parallel to the edge of the upper part 220-2 on the opening 220-1 side. The protruding rib 225 may extend parallel to the direction in which the multiple holes are formed.

[0108] When the protruding rib 225 is formed to extend along multiple holes, it is possible to effectively prevent cracks or damage in the upper part (220-1) where the multiple holes are formed. Even when an external force is applied, the pressure is distributed in proportion to the degree to which the protruding rib 225 is extended, thus preventing cracks or damage in the upper part 220-2.

[0109] Figure 21 is a perspective view showing an internal rib 226 according to one embodiment of the present invention, and Figure 22 is a front view showing an internal rib 226 according to one embodiment of the present invention. The above description of the embodiments can be applied to this embodiment in the same or similar manner. The following description will be made with reference to Figures 21 and 22.

[0110] <Structure of internal rib 226> The upper part 220-2 may include an internal rib 226. For example, the internal rib 226 may protrude toward the insertion space V. Alternatively, the internal rib 226 may protrude in a direction parallel to the direction DI toward the insertion of the second connector 300.

[0111] The internal ribs 226 can be formed in a region other than the insertion path leading to the insertion space V of the second connector 300. In 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 can be formed with a corresponding structure.

[0112] The internal rib 226 can protrude by a range of 1 to 2 times the thickness T of the upper part 220-2. For example, if the thickness T of the upper part 220-2 is in the range of 0.4 mm to 0.5 mm, the internal rib 226 can protrude by a range of 0.8 mm to 1.0 mm. Designing the degree of protrusion of the internal rib 226 to be in the range of 1 to 2 times the thickness T of the upper part 220-2 effectively ensures rigidity, apart from further protrusion. However, the above numerical ranges are illustrative and not limiting.

[0113] The upper section 220-2 may include a plurality of internal ribs 226. For example, the internal ribs 226 may project toward the insertion space V. Alternatively, the internal ribs 226 may be formed symmetrically around a projecting rib 225.

[0114] Multiple internal ribs 226 can be formed alternately with holes 230. For example, multiple internal ribs 226 can be formed alternately with holes 230 based on the inner surface of the upper part 220-2. Specifically, the holes 230 may consist of two holes, and the internal ribs 226 may include three internal ribs that are formed alternately spaced apart, flanking each of the two holes 230.

[0115] The internal ribs 226 can reinforce the rigidity of the thin thickness T of the upper part 220-2. Furthermore, the internal ribs 226 can reinforce the rigidity of the upper part 220-2 where the holes 230 are formed.

[0116] Figure 23 is a front view showing the arrangement of the protruding rib 225 and internal rib 226 according to one embodiment of the present invention. The above description of the embodiment can be applied identically or similarly to this embodiment.

[0117] <Arrangement of protruding ribs 225 and 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 the edge of the upper part 220-2 on the opening 220-1 side toward the opening 220-1 side from the hole 230. The first connector housing 220 may also include an internal rib 226 that protrudes from the upper part 220-2 toward the insertion space V.

[0118] The protruding rib 225 and the internal rib 226 may include overlapping areas. For example, the protruding rib 225 and the internal rib 226 may include overlapping areas along their edges when viewed from the opening 220-1 side in the direction DI into which the second connector 300 is inserted.

[0119] Referring to Figure 23, the internal rib 226 can project toward the insertion space V with a predetermined projection length B1. The internal rib 226 can also extend along the edge of the upper part 220-2 on the opening 220-1 side with a predetermined extension length B2. In this case, the projection rib 225 and the internal rib 226 can form a predetermined overlap length B3. The length of the overlapping region can be the overlap length B3. Specifically, the overlap length B3 can 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.

[0120] Multiple internal ribs 226 can be formed, and these multiple internal ribs 226 may have different widths. Specifically, the internal rib 226 can include three internal ribs. The three internal ribs can include a central rib formed between two holes and having a first width, and an outer rib formed outside the two holes and having a second width greater than the first width.

[0121] The central rib of the three internal ribs can protrude more toward the insertion space than the outer ribs. The central rib can be more likely to make contact when the second connector 300 is inserted into the insertion space, as viewed from the insertion path. The central rib's protrusion can reinforce its strength and prevent damage due to contact. It can also act as a guide when the second connector 300 is inserted. The central rib may extend to the area where the protruding rib 225 protrudes. Alternatively, the central rib can extend further toward the opening 220-1 than the outer ribs. The width and degree of protrusion of the internal ribs described above can be in various embodiments depending on the number, position, and size of the holes 230.

[0122] The protruding ribs 225 and internal ribs 226 can have their protrusion degrees A' and B1 determined according to the thickness T of the upper part 220-2, respectively. When the protrusion degrees A' and B1 are determined according to the thickness T of the upper part 220-2, the rigidity of the thin thickness T of the upper part 220-2 in which the hole 230 is formed can be adaptively reinforced according to the structure.

[0123] [Theme 4] <Anti-detachment structure for fastening housing 400> Figure 24 is a perspective view showing a second connector according to one embodiment of the present invention.

[0124] Referring to Figure 24, the connector module 100 can include a first connector 200 and a second connector 300 (see Figure 5).

[0125] The first connector 200 can be electrically connected to the control unit 10. The first connector 200 may include a first connector housing 220 and a first conduction part 210.

[0126] The first connector housing 220 can form the external appearance of the first connector 200. For example, the first connector housing 220 may include a housing shape having a structure formed with a recess on the inside. Specifically, the first connector housing 220 may include an opening 220-1 that is open on one side, and may include a first recessed portion 220a that is formed recessed inward from the opening 220-1. The second connector 300 can be inserted and coupled into the first recessed portion 220a.

[0127] The first conduction unit 210 is connected to the first connector housing 220 and can be electrically connected to the control unit.

[0128] The second connector 300 can be electrically connected to the first connector 200. For example, the second connector 300 can be inserted and coupled to the first connector 200. Specifically, the second connector 300 can 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 can be electrically connected to the first connector 200, i.e., the first conduction part 210, while the other side of the second connector 300 can be electrically connected to a plurality of battery cells 2.

[0129] The second connector 300 may include a second connector housing 320, a second conduction section 310, and a fastening housing 400.

[0130] The second connector housing 320 can form the external appearance of the second connector 300 and be configured to be inserted 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.

[0131] The second connector housing 320 is connected to the frame 321 and joint part It can include 322 (see Figure 24).

[0132] The frame 321 can be inserted 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.

[0133] joint part 322 can be connected to one side of frame 321 and coupled to the first connector 200. For example, joint part 322 can be connected to the top surface of frame 321. joint part 322 can be connected to the first connector 200 by coupling with the inner upper surface of the first connector housing 220 while connected to the upper surface of the frame 321.

[0134] in this case, joint part 322 can be connected to the first connector 200 by a hook coupling. For example, joint part 322 may include a lever form. Specifically, there is a portion formed through the upper surface of the first connector housing 220, i.e., a hole 230, such that the upper surface of the first connector housing 220 and the first recessed portion 220a communicate with each other. joint part 322 can be coupled to the through portion on the upper surface of the first connector housing 220.

[0135] More specifically, based on the direction in which the second connector 300 is inserted into the first connector 200, joint part With the front of 322 connected to frame 321, joint part The rear of 322 is movable in an upward or downward direction.

[0136] joint part With 322 separated from the second conduction part 310 by a predetermined distance, the second connector 300 is inserted and coupled to the first connector 200. joint partAfter moving downwards, 322 moves upwards and connects with the through portion of the upper surface of the first connector housing 220, joint part 322 connects the first connector 200 and the second connector 300 to each other. join It is possible. In this case, joint part 322 can also be separated from the second conduction section 310 by a predetermined distance.

[0137] Conversely, when subjected to external forces from users, etc. joint part When 322 moves to the bottom, join The restriction is released, and the second connector 300 can be detached from the first connector 200.

[0138] Figure 25 is, for example, an enlarged view of a second connector according to one embodiment of the present invention. Referring to Figure 25, joint part 322 may include a protruding portion 322-1 that is formed to protrude upward on the upper surface. With the first connector 200 and the second connector 300 connected, the user can joint part The second connector 300 can be disconnected from the first connector 200 by pressing the protruding portion 322-1 of 322.

[0139] The second conduction section 310 can be electrically connected to the first conduction section 210 by at least a portion of it being inserted and coupled to the frame 321. In other words, the second conduction section 310 is configured to be electrically connected to multiple battery cells, and can receive electrical signals from multiple battery cells and transmit them to the first conduction section 210. For example, the second conduction section 310 may include an FFC (Flexible Flat Cable).

[0140] Inside frame 321, frame 321 and joint part A region is formed surrounded by 322, with one side open, and the second conduction part 310 is frame 321 and joint part It can be inserted and coupled to frame 321 so as to be enclosed by 322.

[0141] The fastening housing 400 can fasten the second connector housing 320 and the second conduction part 310 together. For example, the fastening housing 400 can enclose the second connector housing 320 with the second conduction part 310 inserted and coupled into the second connector housing 320. Specifically, the fastening housing 400 can crimp and grip the second connector housing 320 and the second conduction part 310 to prevent the second conduction part 310 from detaching from the second connector housing 320.

[0142] At the same time, the fastening housing 400, joint part The stepped structure 410-1 that contacts one surface of 322, joint part This can restrict frame 322 from leaving frame 321. joint part Due to the structure in which a portion of 322 is locked to the fastening housing 400, joint part This prevents the phenomenon of 322 being excessively distorted or shifted upwards.

[0143] Figure 26 is a front view of a fastening housing according to one embodiment of the present invention.

[0144] Referring to Figure 26, the fastening housing 400 may include a fastening body 410 and a fastening portion 420.

[0145] The fastening body 410 can contact the second connector housing 320 and the second conduction part 310 to fasten the second connector housing 320 and the second conduction part 310. For example, the fastening body 410 can joint part While positioned behind 322, joint part By enclosing a portion of the rear of 322 and crimping the second conduction part 310, the second connector housing 320 and the second conduction part 310 can be fastened together.

[0146] The fastening body 410 may include a first fastening body 411 and a second fastening body 412.

[0147] The first fastening body 411 is positioned with reference to the direction in which the second connector 300 is inserted into the first connector 200. joint part It can be located behind 322. For example, the first fastening body 411 is joint part It can be positioned behind 322 and formed and arranged to extend to both sides when viewed in the direction of insertion into the second connector 300. That is, the first fastening body 411 is joint part It can be formed along the rear of 322.

[0148] The second fastening body 412 is formed on both sides of the first fastening body 411. joint part It can enclose parts of both sides of 322. In this case, joint part A portion of the second fastening body 412, which encloses parts of both sides of 322, may include a stepped portion 410-1. In other words, the fastening body 410 is joint part It may include a stepped portion 410-1 that is in contact with one surface of 322 and is formed in a stepped shape. However, the stepped portion 410-1 is not necessarily joint part It is not formed on both sides of 322, joint part They may be formed corresponding to at least one of the two sides of 322.

[0149] When viewing the direction in which the second connector 300 is inserted, joint part 322 is locked to the stepped portion 410-1 of the fastening body 410, thereby moving upward joint part Movement of 322 can be restricted. For example, joint part With the rear of 322 moved upward, the stepped portion 410-1 is joint part It can make contact with the rear of 322.

[0150] Specifically, referring to Figure 25, joint part When viewed from the front of 322, the stepped portion 410-1 is, joint part A first surface 410a is formed on the upper side of 322, and one side is connected to the lower side of the first surface 410a. joint part The second surface 410b is in contact with the upper surface of 322 and is connected to the other side of the second surface 410b. joint partA third surface 410c can be formed along the side surface of 322. In this case, joint part The upper surface of 322 is locked to the second surface 410b, joint part The upper surface of 322 can be located below the extension of the second surface 410b. That is, joint part To prevent the upper surface of 322 from moving to the upper side of the second surface 410b, joint part The movement radius can be limited to 322.

[0151] joint part As 322 is locked to the second surface 410b, on the upper side of the second surface 410b joint part The movement of 322 can be restricted. According to such a structure, joint part The movement of 322 to a predetermined radius is restricted, preventing problems such as excessive deformation or detachment from the upper side of frame 321.

[0152] result, joint part By preventing the problem of 322 floating upward and undergoing deformation or breakage during firing, the structural stability of the second connector 300 is increased, and the coupling stability of the first connector 200 and the second connector 300 can be improved.

[0153] Figure 27 shows an embodiment of the present invention. joint part And a close-up view of the fastening housing.

[0154] Referring to Figure 27, the upper surface of the first fastening body 411 is joint part It can be positioned below the upper surface of the protruding portion 322-1 of 322. In other words, with respect to the extended surface of the upper surface of the first fastening body 410, joint part The protruding portion 322-1 of 322 can be formed to be higher. joint part Since the protruding portion 322-1 of 322 is located above the upper surface of the first fastening body 411, the user can more easily pressurize and handle the protruding portion, thereby increasing the ease of use of the connector module 100.

[0155] In this case, the upper surface of the first fastening body 411 and joint partThe distance S between the upper surface of the protruding portion 322-1 of 322 can be 0.5 mm to 0.7 mm. joint part If the distance S between the protruding portion 322-1 of 322 and the upper surface is less than 0.5 mm, then the upper surface of the first fastening body 411 and joint part It is difficult to distinguish between the upper surface of the protruding portion 322-1 of 322 in terms of use, which may reduce the usability of the connector module 100. Conversely, the upper surface of the first fastening body 411 and joint part If the distance S between the upper surface of the protruding portion 322-1 of 322 exceeds 0.7 mm, joint part The height of the protruding portion 322-1 of 322 becomes too high, which increases the overall height of the connector module 100 and may inefficiently occupy space inside the battery module 1.

[0156] Furthermore, when the height of the first fastening body 411 is L1 and the height of the second fastening body 412 is L2, the equation 0.3 ≤ L1 / L2 ≤ 0.5 can be satisfied. When L1 / L2 is less than 0.3, the difference in height between the first fastening body 411 and the second fastening body 412 becomes small. joint part The position of the protruding portion 322-1 of 322 becomes difficult to determine, which may reduce the ease of use of the connector module 100. Conversely, if L1 / L2 exceeds 0.5, the height of the first fastening body 411 becomes considerably smaller, which may make the first fastening body 411 more susceptible to damage, and the height of the second fastening body 412 becomes considerably larger, which may cause an increase in the overall height of the connector module 100.

[0157] The height L1 of the first fastening body 411 (or, in other words, the thickness of the first fastening body 411) can have a value of 0.8 to 1.2 mm. Due to the thickness of the first fastening body 411, joint part When pressing on 322, the hand can be supported to prevent excessive downward pressure. This is because, joint part By allowing the 322 to move only within its permissible range, the risk of damage can be reduced, and convenience of use can be enhanced.

[0158] The fastening portion 420 is connected to one side of the fastening body 410 and can be coupled to the side of the second connector housing 320. For example, the fastening portion 420 may be formed to extend from both sides of the fastening body 410 and enclose 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 can be coupled to both sides of the frame 321.

[0159] The fastening portion 420 can be connected to the side surface of the frame 321 by a ring structure. Specifically, one side of the fastening portion 420 is connected to the fastening body 410, and a ring structure 421 can be formed at the other end of the fastening portion 420. The ring structure 421 of the fastening portion 420 is formed along the side surface of the frame 321 and can be fastened to the underside of the frame 321.

[0160] More specifically, the fastening portion 420 includes an inclined surface that slopes toward the 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 portion 420. The ring structure 421 of the fastening portion 420 can be locked to the side surface of the frame 321 by a sliding mechanism in which the inclined surface of the fastening portion 420 moves along the inclined surface of the side surface of the frame 321. In other words, with the second conduction portion 310 inserted into the frame 321, the fastening housing 400 is fastened in a direction perpendicular to the direction in which the second conduction portion 310 was inserted, and as the fastening housing 400 fastens, the inclined surface of the fastening portion 420 moves along the inclined surface of the side surface of the frame 321, thereby allowing the ring structure 421 of the fastening portion 420 to be coupled to the lower side of the frame 321.

[0161] [Theme 5] <Through-hole structure of fastening housing 400> Figure 28 is a perspective view showing how the second conduction part according to one embodiment of the present invention is inserted into the second connector housing; Figure 29 is a perspective view showing how the fastening housing according to one embodiment of the present invention is fastened to the second connector housing and the second conduction part; and Figure 30 is a cross-sectional view of a connector module according to one embodiment of the present invention.

[0162] Referring to Figures 28 to 30, the fastening housing 400 can fasten the second connector housing 320 and the second conduction part 310 by passing through them. For example, the fastening housing 400 may further include fastening pins 430 that protrude from the fastening body 410 and pass through the second connector housing 320 and the second conduction part 310. That is, the fastening pins 430 can be formed to protrude from the lower surface of the fastening body 410 toward the second conduction part 310. The fastening pins 430 can be formed in pairs on both sides of the lower surface of the fastening body 410.

[0163] Specifically, the fastening body 410 is formed to protrude toward the second conduction part 310, and can form a portion that contacts the second conduction part 310. In addition, the fastening body 410 is formed to protrude toward the second conduction part 310, and can form a portion that contacts the conduction film 311. The fastening pin 430 can be formed to protrude from a portion that protrudes toward the underside of the fastening body 410. In other words, the lower surfaces of the first fastening body 411 and the second fastening body 412 can 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 have a structure that protrudes further toward the second conduction part 310 compared to the lower surface of the fastening part 420, and the fastening pin 430 can be formed to protrude from such lower surfaces of the first fastening body 411 and the second fastening body 412.

[0164] The end portion of the fastening pin 430 may include at least one of the following shapes: a curved shape or a horn shape. Such a structure for the end portion of the fastening pin 430 can increase manufacturability during the process of coupling the fastening pin 430 with the second connector housing 320.

[0165] The second connector housing 320 may include a through-formed first fastening opening 321a. For example, the first fastening opening 321a can be formed on the inner lower surface of the frame 321. Specifically, the frame 321 and joint partThe second conductive part 310 is inserted and coupled into the recessed portion 320-1 surrounded by 322, and the recessed portion 320-1 is used as a reference. joint part The inner lower surface of frame 321 is located on the opposite side of 322, and a first fastening opening 321a can be formed through the inner lower surface of frame 321. That is, the first fastening opening 321a can be formed to penetrate from the inner lower surface of frame 321 to the lower surface of frame 321.

[0166] The second conduction portion 310 may include a through-formed second fastening opening 310a. That is, the second fastening opening 310a can be formed to penetrate from the upper surface to the lower surface of the second conduction portion 310. In this case, with the second conduction portion 310 inserted and coupled to the second connector housing 320, the first fastening opening 321a and the second fastening opening 310a can be formed on the same line. Also, with the second conduction portion 310 inserted and coupled to the second connector housing 320, the fastening pin 430 can be positioned to integrally penetrate the first fastening opening 321a and the second fastening opening 310a.

[0167] The direction in which the second conduction portion 310 is inserted into the second connector housing 320 and the direction in which the fastening pin 430 passes through can be perpendicular to each other.

[0168] With this structure, the fastening pin 430 can restrict the second conduction part 310 from detaching from the second connector housing 320. Specifically, the fastening pin 430 can fix the second conduction part 310 to the second connector housing 320 in such a way that it restricts the movement of the second conduction part 310 in a direction parallel to the direction in which it is inserted into the second connector housing 320.

[0169] The fastening pin 430 is positioned to penetrate the first fastening opening 321a and the second fastening opening 310a, and the fastening portion 420 is connected to both sides of the frame 321 by a ring structure, thereby further increasing the bonding force between the second connector housing 320 and the second conduction portion 310.

[0170] As a result, the fastening force between the second connector housing 320 and the second conduction part 310 is increased via the fastening pin 430, thereby improving the structural stability of the connector module 100.

[0171] Furthermore, with this fastening pin 430 structure, the contact area of ​​the first conduction part 210 and the second conduction part 310 can be maintained at a constant level. In other words, by fixing the second conduction part 310 in a predetermined position inside the second connector housing 320, the first conduction part 210 and the second conduction part 310 always form a contact area in a constant region, maintaining a pre-planned contact method and circuit arrangement, and improving the quality of electrical signal transmission and reception. As a result, with this structure, electrical signals can be transmitted and received more precisely through the connector module 100, and the control quality of the control unit 10 can be further improved.

[0172] [Theme 6] <Tilt-fixing structure> The frame 321 may include a structure to prevent tilting of the second connector 300. Tilting refers to a phenomenon in which the appearance and angle of the second connector 300 change while it is coupled to the first connector 200. Such tilting occurs due to a weakening of the coupling force between the first connector 200 and the second connector 300, causing problems that impede the structural stability of the connector module 100, such as the second connector 300 floating or detaching from the first connector 200.

[0173] The tilt phenomenon of the second connector 300 can occur due to rotational motion of the second connector 300, such as rolling, yawing, and pitching around each axis. Specifically, referring to Figure 24, there can be rolling motion around the x-axis, pitching motion around the y-axis, and yawing motion around the z-axis. In this case, the x-axis can be formed in a direction parallel to the direction in which the second connector 300 is inserted. The y-axis can be formed perpendicular to the x-axis and parallel to the ground. The z-axis can be formed perpendicular to the x-axis and y-axis and perpendicular to the ground.

[0174] A structure may be needed to prevent such rotational movement and improve the coupling stability of the second connector 300.

[0175] Figure 31 is an enlarged internal view of a connector module according to one embodiment of the present invention.

[0176] Referring to Figures 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 that project outward from one side of the frame 321 body.

[0177] The first protruding portion 321-1 can be formed to protrude forward from the main body of the frame 321 with respect to the direction in which the second connector 300 is inserted. That is, the first protruding portion 321-1 can be a portion that extends from the main body of the frame 321 in the x-axis direction (see Figure 24) and is inserted into the first connector 200. For example, the first connector 200 further includes a second recessed portion 220b formed recessed in front of the first recessed portion 220a, and the first protruding portion 321-1 can be inserted into the second recessed portion 220b.

[0178] The second recessed portion 220b can be a portion formed by recessing from the first recessed portion 220a in the x-axis direction on the inside of 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 can be greater than the height of the second recessed portion 220b. That is, if 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 can be satisfied. Correspondingly, when viewed from the side, the height of the first protruding portion 321-1 can be formed to protrude from the frame 321 body such that it is less than the height of the frame 321 body.

[0179] 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 on one side to the first surface 220b-1 and forming the front surface, and a third surface 220b-3 connected on the other side of the second surface 220b-2 and forming the bottom surface.

[0180] The first surface 220b-1 can be the upper surface of the second recessed portion 220b. The second surface 220b-2 can be the innermost surface, i.e., the front surface, of the second recessed portion 220b. The second surface 220b-2 can be perpendicular to the first surface 220b-1. The third surface 220b-3 constitutes the lower surface of the second recessed portion 220b and can 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 can be formed along the outer surface of the first protruding portion 321-1.

[0181] The first recessed portion 220a is connected to the third surface 220b-3 and may include a support surface 220a-1 extending downward from the third surface 220b-3. That is, the support surface 220a-1 can be formed on the lower side of the first protruding portion 321-1.

[0182] 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, that is, the front surface of the frame 321 body.

[0183] With this structure, the rotational movement of the second connector 300 can be restricted by locking the first protruding portion 321-1 into the second recessed portion 220b. Specifically, pitching motion, which rotates with respect to the y-axis, can be restricted.

[0184] To maximize the prevention of pitching motion, each surface of the first recessed portion 220a and the second recessed portion 220b can satisfy a specific condition. For example, the length F1 of the support surface 220a-1 of the first recessed portion 220a can 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 considerably smaller, reducing the support area for preventing pitching, and making it impossible to effectively prevent pitching motion 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, it may increase the unnecessary conductive area, potentially creating a conductive area that was not intended in the design.

[0185] Furthermore, the length F2 of the second surface 220b-2 of the second recess can satisfy a specific condition. For example, the length F2 of the second surface 220b-2 can be between 0.9 mm and 1.1 mm. If the length F2 of the second surface 220b-2 is less than 0.9 mm, the depth of the recess in the second recess 220b will be smaller, which may reduce the tilt prevention effect. Conversely, if the length F2 of the second surface 220b-2 exceeds 1.1 mm, the length will be longer than the thickness of the first protruding portion 321-1, which may cause damage to the first protruding portion 321-1 due to the tilt phenomenon.

[0186] Furthermore, the first protruding portion 321-1 can be formed along a direction extending to both sides with respect to the direction in which the second connector 300 is inserted. In other words, the first protruding portion 321-1 can be formed in a direction parallel to the y-axis direction. With such a structure, the form of the first protruding portion 321-1 can prevent the second connector 300 from rolling when it is inserted and coupled to the first connector 200.

[0187] The second protruding portion 321-2 can be formed to protrude above or below the frame 321 body with reference to the direction in which the second connector 300 is inserted. For example, the second protruding portion 321-2 can be formed to protrude from the lower surface of the frame 321 body toward the second conduction portion 310. Specifically, the second protruding portion 321-2 can be formed to protrude downward parallel to the z-axis direction.

[0188] Referring to Figure 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 formed recessed above or below the first recessed portion 220a, and the second protruding portion 321-2 can be inserted into the third recessed portion 220c. That is, the third recessed portion 220c can be formed as an extension along the z-axis from the first recessed portion 220a.

[0189] When viewed from the direction in which the second connector 300 is inserted, i.e., from the x-axis direction, the third recessed portion 220c can be formed on both sides of the first recessed portion 220a. Similarly, the second protruding portions 321-2 can be formed on both sides of the frame 321 so as to correspond to the third recessed portion 220c.

[0190] Furthermore, the third recessed portions 220c formed on both sides below the first recessed portion 220a can form a stepped structure. In other words, when viewed in the x-axis direction, the outermost inner surface of the third recessed portion can have a stepped and inclined structure relative to the inner surface of the first recessed portion 220a.

[0191] With this structure, the second protruding portion 321-2 can be inserted into and coupled with the third recessed portion 220c and locked to the third recessed portion 220c, thereby restricting the rotation of the second connector 300. Specifically, the mating of the second protruding portion 321-2 can prevent the yawing motion of the second connector 300. To maximize the above 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.

[0192] [Theme 7] <Structure for improving the fixing force of the first conduction section 210 and the second conduction section 310> Figure 32 is an internal cross-sectional view of a connector module according to one embodiment of the present invention.

[0193] Referring to Figure 32, the first conduction part 210 can be electrically connected to only one surface of the second conduction part 310. In other words, the first conduction part 210 is not a structure that encloses the second conduction part 310, but can only contact one surface of the second conduction part 310. For example, the first conduction part 210 can be electrically connected to the second conduction part 310 by contacting the lower surface of the second conduction part 310 while positioned through the first connector housing 220.

[0194] Specifically, referring to Figures 25 and 28, frame 321 and joint part The second connector 300 is inserted and coupled into the recessed portion surrounded by 322, and the recessed portion is used as a reference. joint part The inner lower surface of frame 321 is located on the opposite side of 322, and the inner lower surface of frame 321 can support the lower surface of the second conduction section 310. Referring to Figure 13a, a plurality of holes 350-1 can be formed through the inner lower surface. That is, a plurality of holes 350-1 are formed through the space between the comb-shaped structures 350, and the first conduction section 210 can contact the lower surface of the second conduction section 310 through the through-formed holes 350-1.

[0195] With this structure, the first conduction part 210 contacts and electrically connects to only one surface of the second conduction part 310, rather than both surfaces of the second conduction part 310. This reduces the height of the coupling structure between the first conduction part 210 and the second conduction part 310, thereby reducing the overall height of the connector module 100. However, a problem may arise in which the contact force between the first conduction part 210 and the second conduction part 310 becomes weaker, and the connector module 100 may include a structure to prevent this contact force weakening problem.

[0196] joint part By contacting the upper surface of the second conduction part 310 and applying pressure to the upper surface of the second conduction part 310, the contact force between the first conduction part 210 and the second conduction part 310 can be strengthened. For example, joint part The front of 322 is fixedly connected to the upper surface of frame 321. joint part The rear of 322 is movable in the upward or downward direction. Here it is connected to the upper surface of frame 321. joint part The front of 322 may include a ring structure that forms an empty space inside. That is, joint part 322, containing an elastic material and having a ring structure, can undergo elastic deformation, with its rear end moving upward or downward.

[0197] in particular, joint part 322 may include a contact portion 322-2 that contacts the upper surface of the second conduction portion 310. joint part 322 is the first connector 200 and join do joining part It may contain 322-3. joining part The front of it is connected to the front of the contact portion 322-2, joining part 322-3 is formed to extend rearward with respect to the insertion direction of the second connector 300, joining part A portion of 322-3 can be separated from the contact portion 322-2 by a predetermined distance. joining part 322-3 connects to or disconnects from the first connector housing 220 by a hole 230 formed through the upper surface of the first connector housing 220, thereby connecting the second connector 300 to the first connector 200. join or joinIt can be deactivated.

[0198] More specifically, the contact portion 322-2 contacts the upper surface of the second conduction portion 310, joint part With the front of 322 fixed, using the principle of leverage, joining part An external force is applied to the rear upper surface of 322-3 joining part The rear of 322-3 can move downward and become closer to the contact portion 322-2. In this process, after the second connector 300 is inserted into the first connector 200, joining part 322-3 moves upwards again. joining part A portion of the upper surface of 322-3 is formed to protrude and fits into a hole 230 formed through the upper surface of the first connector housing 220, thereby connecting the second connector 300 to the first connector 200. join It is possible. The first connector 200 and the second connector 300 join The process of releasing it can be done by the reverse action. As a result, joint part According to the structure of 322, the second conduction part 310 can be more firmly fixed by fitting between the contact part 322-2 and the first conduction part 210.

[0199] Furthermore, in order to further enhance the fixing effect, joint part Each part of 322 can satisfy a specific condition.

[0200] 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 can 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, and the pressure that the contact portion 322-2 exerts on the second conduction part 310 becomes low, which may cause the function of the contact portion 322-2 in supporting the second conduction part 310 and strengthening the fixing force of the first conduction part 210 and the second conduction part 310 to be lost. Conversely, if the height G1 of the contact portion 322-2 exceeds 1.5 mm, joint part The problem is that the thickness of 322 itself increases, which increases the overall height of the connector module 100, and the contact portion 322-2 joining part The separation distance from 322-3 has become too small. joint part Problems may arise where the 322 function does not operate smoothly.

[0201] Furthermore, the length G2 of the contact portion 322-2 formed along the direction of insertion and coupling of the second connector 300 and in contact with the second conduction portion 310 can be 1.8 mm to 2.1 mm. If the length G2 of the contact portion 322-2 in contact with the second conduction portion 310 is less than 1.8 mm, the contact force between the contact portion 322-2 and the second conduction portion 310 will be weakened, and the function of the contact portion 322-2 in strengthening the fixing force of the first conduction portion 210 and the second conduction portion 310 may be lost. Conversely, if the length G2 of the contact portion 322-2 in contact with the second conduction portion 310 exceeds 2.1 mm, joint part The separation space between 322 and the second conduction part 310 is excessively infringed. joint part The functionality of 322 may be reduced.

[0202] Furthermore, contact portion 322-2 and joining part The separation distance G3 from 322-3 can be 0.23 mm to 0.27 mm. Contact portion 322-2 and joining part If the separation distance G3 from 322-3 is 0.23 mm or less, joint part A problem may occur where the function of 322 deteriorates. Conversely, contact portion 322-2 and joining part If the separation distance G3 from 322-3 exceeds 0.27 mm, the contact portion 322-2 and joining part The thickness of 322-3 may become too thin, potentially leading to problems where it is easily damaged by external factors.

[0203] When viewed from the side with reference to the direction in which the second connector 300 is inserted and coupled, joint part322 can satisfy 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 conduction portion 310 weakens, and the function of the contact portion 322-2 in strengthening the fixing force between the first conduction portion 210 and the second conduction 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 weakens, potentially leading to problems such as easy breakage.

[0204] Also, referring to Figure 31, joint part The length from the frontmost to the rearmost part of 322 is G5. joint part When the length from the foremost surface of 322 to the rearmost surface of contact portion 322-2 is G4, the condition 2 ≤ G5 / G4 ≤ 2.5 can be satisfied. If G5 / G4 is less than 2, the area on the lower surface of contact portion 322-2 that supports the second conduction portion 310 becomes smaller. joining part In 322-3, this principle could not be fully applied. joint part The functionality of 322 may be reduced. Conversely, if G5 / G4 exceeds 2.5, joint part Does 322 occupy excess space inside the connector module 100? joining part 322-3 is locked to contact portion 322-2 joining part The separation distance between 322-3 and the second conduction part 310 is not adequately ensured. join Problems such as reduced functionality may occur.

[0205] Finally, referring to Figure 31, joining part 322-3 effectively moves downward, and the first connector housing 220 join or join In order to be deactivated, joining part The rear lower surface of 322-3 may include an inclined surface 322-3a. Specifically, joining part The further back you go in the 322-3 joining part The distance between 322-3 and the second conduction part 310 will increase. joining part An inclined surface 322-3a can be formed on the rear lower surface of 322-3. For example, joining partThe angle θ at which the inclined surface 322-3a is inclined with respect to the extension of the front lower surface of 322-3 can be between 5 and 8 degrees. If the angle θ at which the inclined surface 322-3a is inclined is less than 5 degrees, joining part The separation distance between the rearmost lower surface of 322-3 and the second conduction section 310 is not adequately ensured. joint part 322 join The function may be impaired. Conversely, if the inclination angle θ of the inclined surface 322-3a exceeds 8 degrees, joining part The thickness of 322-3 may become too thin, potentially leading to problems such as easy damage and deformation from external impacts.

[0206] in this case, joint part 322 is separated from the second conduction part and is more effective join In order to perform the function, joint part The distance G6 between the rearmost part of 322 and the second conduction part can be 0.7 to 0.8 mm. To increase the fixing force and contact force between the first conduction part 210 and the second conduction part 310, the fastening housing 400 can further fix the second conduction part 310 to the second connector housing 320 by fastening structure. The fastening housing 400 may include a fastening body 410 and a fastening part 420.

[0207] The fastening portion 420 is connected to one side of the fastening body 410 and can be coupled to the side of the second connector housing 320. For example, the fastening portion 420 may be formed to extend from both sides of the fastening body 410 and enclose 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 can be coupled to both sides of the frame 321.

[0208] The fastening portion 420 can be connected to the side surface of the frame 321 by the ring structure 421. Specifically, one side of the fastening portion 420 is connected to the fastening body 410, and the ring structure 421 can be formed at the other end of the fastening portion 420. The ring structure 421 of the fastening portion 420 is formed along the side surface of the frame 321 and can be fastened to the underside of the frame 321.

[0209] More specifically, the fastening portion 420 includes an inclined surface that slopes toward the side surface of the frame 321, and the side surface of the frame 321 can include an inclined surface formed to correspond to the inclined surface of the fastening portion 420. By means of a sliding method in which the inclined surface of the fastening portion 420 moves along the inclined surface of the side surface of the frame 321, the ring structure of the fastening portion 420 can be locked to the side surface of the frame 321. That is, in a state where the second conductive portion 310 is inserted into the frame 321, the fastening housing 400 is fastened in a direction perpendicular to the direction in which the second conductive portion 310 is inserted, and the inclined surface of the fastening portion 420 moves along the inclined surface of the side surface of the frame 321 when the fastening housing 400 is fastened, so that the ring structure 421 of the fastening portion 420 can be coupled to the lower side of the side surface of the frame 321.

[0210] As a result, the first conductive portion 210 contacts only the single surface of the second conductive portion 310, joint part By strengthening the fixing force of the first conductive portion 210 and the second conductive portion 310 by the frame 322 and the fastening housing 400, the overall height of the connector module 100 is reduced, and the connector module 100 can more effectively occupy space within the battery module. Specifically, the height H3 of the connector module 100 can be 3.5 mm to 4 mm. That is, the height of the first connector 200 can be 3.5 mm to 4 mm.
