Description

Technical Field

[0001] This application claims the benefit of priority based on Korean Patent Application No. 10-2023-0085228 filed on June 30, 2023, and all the contents disclosed in the literature of the Korean Patent Application are incorporated herein by reference in their entirety. The present invention relates to an inspection device for inspecting the performance of a connector provided in a battery module.

Background Art

[0002] In order to solve environmental pollution caused by the use of petroleum resources and the problem of energy source shortage due to the depletion of petroleum resources, research and development on power generation based on environmentally friendly energy sources are being carried out. In particular, research on secondary batteries that can be repeatedly charged and discharged and have a high utilization rate is actively conducted, and research is being carried out from various viewpoints such as the materials, structure, process, and stability of secondary batteries.

[0003] Generally, types of secondary batteries include nickel-cadmium batteries, nickel-metal hydride batteries, lithium-ion batteries, and lithium-ion polymer batteries. Such secondary batteries are used not only in small products such as digital cameras, P-DVDs, MP3Ps, mobile phones, PDAs, portable game devices, power tools, and e-bikes, but also in large products that require high power such as electric vehicles and hybrid vehicles, power storage devices for storing surplus generated power and renewable energy, and backup power storage devices.

[0004] To manufacture such secondary batteries, first, an electrode active material slurry is applied to a positive electrode current collector and a negative electrode current collector to manufacture a positive electrode and a negative electrode, and by laminating them on both sides of a separator, an electrode assembly of a predetermined shape is formed. Then, the electrode assembly is housed in a battery case and sealed after injecting an electrolyte.

[0005] A battery module is manufactured by arranging and housing multiple secondary batteries produced in this manner. In this case, a control unit is designed to detect the state of the multiple secondary batteries and control their operation. For example, the control unit may include a PCB (Printed Circuit Board) or a BMS (Battery Management System) and receive or transmit electrical signals from the multiple secondary batteries. In other words, the control unit receives state information of the secondary batteries as electrical signals and controls the operation of the secondary batteries according to their operating status. Furthermore, the control unit can be designed inside a battery pack composed of multiple battery modules and can control the operation of multiple battery modules.

[0006] Furthermore, connectors are designed to electrically connect multiple battery modules and control units, or to electrically connect multiple battery modules to each other. For example, a connector may include terminals that are structurally connected to the outer surface of a battery module and electrically connected to the battery module. That is, the connector may include a insert-and-connect structure, and a portion of the connector may be designed to be detachable from or attached to the battery module.

[0007] Thus, during the process of using connectors, problems such as connector malfunction can occur. Connector testing equipment is sometimes used to check whether a connector is functioning correctly. By inserting and coupling the connector and electrically connecting it, the connector testing equipment can check whether the connector is properly sending and receiving electrical signals with the battery module.

[0008] However, during the process of inserting and coupling the connector inspection device into the connector, problems may occur where the device is not properly coupled, resulting in damage to the probe pin of the inspection device or failure to perform the inspection correctly.

[0009] Therefore, in the process of inspecting the performance of connectors, it is necessary to have an inspection device that can adjust the orientation and coupling angle of the inspection device so that the connector can be coupled to the correct position. [Overview of the Initiative] [Problems that the invention aims to solve]

[0010] One problem that the present invention aims to solve is to provide a connector inspection device that adjusts the coupling position and direction so that the connector is coupled to the correct position. One problem that the present invention aims to solve is to provide a connector inspection device that protects the detection member from external factors before coupling with the connector, and is designed so that the detection member protrudes only when coupling with the connector. [Means for solving the problem]

[0011] In an inspection device for testing the performance of a battery module connector, the connector inspection device according to an embodiment of the present invention includes: a first body portion; a second body portion whose one surface is connected to one surface of the first body portion; a third body portion whose one surface is connected to the other surface of the second body portion and includes a detection member that connects to the connector and receives an electrical signal from the connector; and a fourth body portion whose one surface faces the other surface of the third body portion, positions the detection member inward, and is movable toward the third body portion, wherein the second body portion, the third body portion, and the fourth body portion are movable along one surface of the first body portion.

[0012] The second body portion may include a second body body whose one surface is connected to one surface of the first body portion and whose other surface is connected to one surface of the third body portion, and a connecting portion which protrudes from the second body body and is inserted and coupled to the first body portion.

[0013] The first body portion includes an insertion hole formed through it so that the coupling portion can be inserted, and a clearance space can be formed between the coupling portion and the insertion hole. As the connecting portion moves inside the insertion hole due to the available space, the second body can move along one surface of the first body portion.

[0014] The second body is movable in a direction parallel to one surface of the first body. The connecting portion can move inside the insertion hole in a direction perpendicular to the direction in which it is inserted into the insertion hole.

[0015] The fourth body portion may include a fourth body body whose one surface is connected to the other surface of the third body portion and which is movable toward the third body portion, and a connecting portion which is formed to protrude from the other surface of the fourth body body, which positions the detection member inside and connects with the connector.

[0016] The third body portion may further include a third body body on which one surface is connected to the other surface of the second body portion and on which the detection member is formed, and a compression member provided on the third body body and elastically compressible by the fourth body body.

[0017] The compression member is located in the space between the third body and the fourth body, and as the fourth body moves toward the third body, the compression member can be elastically compressed by the fourth body.

[0018] The third body is formed through and includes a compression hole in which the compression member is located, and both ends of the compression member can contact the other surface of the second body and one surface of the fourth body.

[0019] The connecting portion may include a connecting hole formed through it so that the detection member can be inserted. As the fourth body moves toward the third body portion, the detection member can move along the connection hole and protrude from the outer surface of the connection portion.

[0020] The detection member can be connected to the connector while protruding from the outer surface of the connection portion. The second body portion, the third body portion, and the fourth body portion are integrally connected and can move together. The detection member can include a pin form.

[0021] The connector inspection apparatus according to an embodiment of the present invention can further include a circuit board positioned between the other surface of the second body portion and one surface of the third body portion and electrically connected to the detection member.

Effects of the Invention

[0022] According to a preferred embodiment of the present invention, by adjusting the coupling position and direction so as to be coupled to a fixed position of the connector, it is possible to prevent problems such as damage to the detection member or incorrect inspection.

[0023] According to a preferred embodiment of the present invention, by protecting the detection member from external factors before coupling with the connector and forming it so that the detection member protrudes only when coupling with the connector, it is possible to prevent in advance the problem of damage to the detection member during coupling. In addition, it can include effects that can be easily predicted by those skilled in the art from the configuration according to a preferred embodiment of the present invention.

However, the present invention may be realized in a variety of different forms and is not limited or restricted by the following embodiments.

[0026] In order to clearly explain the present invention, detailed descriptions of related prior art that are irrelevant to the description or that would unnecessarily obscure the essence of the invention have been omitted. In this specification, when assigning reference numerals to components in each drawing, the same or similar reference numerals shall be assigned to components that are the same or similar throughout the specification.

[0027] 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 appropriately define the concepts of terms in order to best describe their invention.

[0028] Figure 1 is a perspective view showing the connector inspection device 1 and connector C connected according to an embodiment of the present invention. Referring to Figure 1, the connector inspection device 1 according to an embodiment of the present invention can be coupled to and electrically connected to connector C. While inserted and coupled to connector C, the connector inspection device 1 can transmit and receive electrical signals to and from connector C to inspect the performance of connector C. In other words, the connector inspection device 1 can inspect whether connector C is functioning correctly.

[0029] Specifically, connector C can be structurally connected to the outer surface of battery module M and electrically connected to battery module M. In other words, connector C can be designed to include terminals and be detached from or attached to battery module M. That is, connector C may include a female connector C and a male connector C that is inserted into and coupled to the female connector C, and the male connector C may be separated from the female connector C or may be inserted into the female connector C.

[0030] In this case, the coupling portion of the connector inspection device 1, i.e., the connection portion, includes the same structure as the connection portion of the male connector C, and the performance of the female connector C can be inspected by coupling and electrically connecting it to the female connector C.

[0031] Figure 2 is a perspective view of a connector inspection device 1 according to an embodiment of the present invention, and Figure 3 is a cross-sectional view along the line A-A' in Figure 2. Referring to Figures 2 and 3, the connector inspection device 1 may include a first body section 10, a second body section 11, a third body section 12, and a fourth body section 13.

[0032] The first body portion 10 may be the part furthest from the connector C. That is, the second body portion 11, the third body portion 12, and the fourth body portion 13 can be formed sequentially toward the connector C from the first body portion 10. In other words, during the process of the user connecting the connector inspection device 1 to the connector C, the first body portion 10 may be the part that is grasped by the user.

[0033] The second body portion 11 can be connected to the first body portion 10. For example, one surface 11a of the second body portion 11 can be connected to one surface 10a of the first body portion 10, and the other surface 11b of the second body portion 11 can be connected to the third body portion 12, which will be described later. That is, the second body portion 11 can be connected to one surface 11a of the first body portion 10 facing the connector C.

[0034] The third body portion 12 can be connected to the second body portion 11. For example, one surface 12a of the third body portion 12 can be connected to the other surface 11b of the second body portion 11, and the other surface 12b of the third body portion 12 can be connected to the fourth body portion 13, which will be described later.

[0035] Furthermore, the third body portion 12 can be connected to connector C. In other words, the third body portion 12 is electrically connected to connector C and can receive electrical signals from connector C. Specifically, the connector inspection device 1 moves along the X-axis direction, which is the connection direction, and the third body portion 12 can move along the connection direction and connect to connector C.

[0036] The third body portion 12 may include the third body main body 120 and the detection member 121. One surface 12a of the third body 120 can be connected to the other surface 11b of the second body 11. In other words, the third body 120 can be connected to the other surface 11b of the second body 11 facing the connector C.

[0037] The detection member 121 is connected to the connector C and can receive electrical signals from the connector C. For example, the detection member 121 can be formed to protrude toward the connector C from the other surface 12b of the third body 120. In other words, the detection member 121 can be formed to protrude along the X-axis direction from the other surface 12b of the third body 120.

[0038] Specifically, the detection member 121 is formed on the lower side of the other side 12b of the third body 120, moves along the upper surface of the battery module M, and can then be inserted into and coupled to the connector C, thereby being electrically connected to the connector C.

[0039] The detection member 121 may take the form of a pin. In other words, the detection member 121 may include a plurality of probe pins. The probe pins have a structure that tapers towards the end and can contact and electrically connect to the current collection circuit inside the connector C.

[0040] The fourth body portion 13 can be connected to the third body portion 12. For example, one surface 13a of the fourth body portion 13 can face the other surface 12b of the third body portion 12. Also, the detection member 121 can be positioned inside the fourth body portion 13. That is, the fourth body portion 13 can include a structure that surrounds the outside of the detection member 121.

[0041] The second body portion 11, the third body portion 12, and the fourth body portion 13 are movable along one surface 10a of the first body portion 10. The second body portion 11, the third body portion 12, and the fourth body portion 13 are integrally connected and can move together. For example, the second body portion 11, the third body portion 12, and the fourth body portion 13 can be integrally connected by screw connections or the like and can move together in the same direction.

[0042] Specifically, the second body portion 11, the third body portion 12, and the fourth body portion 13 can move in a direction parallel to one surface 10a of the first body portion 10. Referring to Figure 2, the second body portion 11, the third body portion 12, and the fourth body portion 13 can move in the Y-axis or Z-axis direction.

[0043] More specifically, the second body portion 11 may include the second body main body 110 and the connecting portion 111. One surface 11a of the second body body 110 can be connected to one surface 10a of the first body portion 10, and the other surface 11b of the second body body 110 can be connected to one surface 12a of the third body portion 12. The connecting portion 111 is formed to protrude from the second body body 110 and can be inserted and coupled to the first body portion 10. For example, the connecting portion 111 can be formed to protrude toward the first body portion 10 so as to penetrate the first body portion 10 when it is fitted and coupled to the second body body 110.

[0044] The first body portion 10 may include an insertion hole 100 formed through which the connecting portion 111 is inserted. With the connecting portion 111 inserted into the insertion hole 100, the end of the connecting portion 111 can be connected to the inner surface of the first body portion 10 inside the insertion hole 100.

[0045] The connecting portion 111 can move a predetermined distance inside the insertion hole 100. For example, a clearance space can be formed between the connecting portion 111 and the insertion hole 100. In addition, the connecting portion 111 can move a predetermined distance along the inner surface of the first body portion 10 while connected to the inner surface of the first body portion 10 inside the insertion hole 100.

[0046] Specifically, the coupling portion 111 can move inside the insertion hole 100 in a direction perpendicular to the direction in which it is inserted into the insertion hole 100. For example, the coupling portion 111 can be inserted into the insertion hole 100 along the X-axis direction and move a predetermined distance along the Y-axis or Z-axis direction, which is perpendicular to the direction of insertion. Multiple such joint portions 111 and insertion holes 100 can be formed on one surface 10a of the first body portion 10.

[0047] As the connecting portion 111 moves inside the insertion hole 100 due to the available space, the second body body 110 can move along one surface 10a of the first body portion 10. That is, the second body body 110 can move in the Y-axis or Z-axis direction, which is parallel to one surface 10a of the first body portion 10. At the same time, the third body portion 12 and the fourth body portion 13, which are integrally connected to the second body portion 11, can also move in the same direction.

[0048] Figure 4 is a perspective view showing the fourth body portion 13 before movement according to an embodiment of the present invention, Figure 5 is a perspective view showing the fourth body portion 13 after movement according to an embodiment of the present invention, and Figure 6 is a cross-sectional view along the line B-B' in Figure 2.

[0049] Referring to Figures 4 to 6, the fourth body portion 13 is movable toward the third body portion 12. In other words, the fourth body portion 13 can move toward the third body portion 12 in a direction parallel to the X-axis direction. For example, the fourth body portion 13 can move in the opposite direction to the direction in which the connector inspection device 1 connects.

[0050] For the movement of the fourth body portion 13, the third body portion 12 may further include a compression member 122 provided on the third body body 120 and elastically compressible by the fourth body body 130. The compression member 122 includes an elastically deformable spring that compresses under external force and returns to its original shape when the external force is removed.

[0051] The compression member 122 can be located in the space between the third body 120 and the fourth body 130. Specifically, the third body 120 includes a through-hole 1200, and the compression member 122 can be located in the compression hole 1200. Both ends of the compression member 122 can be in contact with the other surface 11b of the second body 11 and one surface 13a of the fourth body 130.

[0052] As the fourth body portion 13 moves toward the third body portion 12, the compression member 122 can be elastically compressed by the fourth body main body 130. That is, with one end of the compression member 122 in close contact with the other surface 11b of the second body portion 11, the other end of the compression member 122 receives an external force from one surface 13a of the fourth body main body 130, allowing the compression member 122 to elastically deform in the opposite direction to the connection direction.

[0053] The third body portion 12 is located inside the compression member 122 and may further include a support member 123 that supports the compression member 122. For example, with the support member 123 inserted into the compression hole 1200, both ends of the support member 123 can be fixedly connected to the second body portion 11 and the fourth body portion 13, respectively.

[0054] With this structure of the support member 123, even if the compression member 122 elastically deforms into a spring shape, the compression member 122 is supported by the support member 123, preventing it from bending and deviating from its deformation path.

[0055] The fourth body section 13 may include the fourth body main body 130 and the connecting section 131. One surface 13a of the fourth body 130 is connected to the other surface 12b of the third body 12, and is movable toward the third body 12. That is, the fourth body 130 can move toward the third body 12 when the connector inspection device 1 is connected to the connector C, while being at a certain distance from the third body 12. At this time, one surface 13a of the fourth body 130 can apply an external force to the compression member 122, causing the compression member 122 to be compressed and deformed.

[0056] The connecting portion 131 can be connected to the connector C. For example, the connecting portion 131 can be formed to protrude from the other surface 13b of the fourth body 130, allowing the detection member 121 to be positioned inside. In other words, the connecting portion 131 can be formed to protrude from the other surface 13b of the fourth body 130 in the X-axis direction, i.e., along the connection direction.

[0057] The connecting portion 131 may include a connecting hole 1310 formed through which the detection member 121 is inserted. As the fourth body 130 moves toward the third body portion 12, the detection member 121 can move along the connecting hole 1310 and protrude from the outer surface of the connecting portion 131.

[0058] The detection member 121 can be connected to the connector C while it is formed to protrude from the outer surface of the connection portion 131. That is, the compression member 122 is compressed by the fourth body portion 13, and the fourth body portion 13 is in close contact with the third body portion 12, allowing the detection member 121 protruding from the outer surface of the connection portion 131 to be connected to the connector C.

[0059] The connector inspection device 1 may further include a circuit board 14 located between the other side of the second body portion 11 and one side of the third body portion 12, and electrically connected to the detection member 121. The circuit board 14 may be a PCB (Printed Circuit Board). The circuit board 14 can receive electrical signals from the detection member 121 related to the performance of the connector C.

[0060] The connector inspection device 1 may further include a tape 15 positioned between the first body portion 10 and the second body portion 11. The tape 15 comprises Teflon® material and can act to allow the second body portion 11 to move more easily along one surface of the first body portion 10.

[0061] Figure 7 is a perspective view showing the connector inspection device 1 according to an embodiment of the present invention before coupling, Figure 8 is a perspective view showing the connector inspection device 1 according to an embodiment of the present invention after coupling, and Figure 9 is a perspective view showing the connector inspection device 1 according to an embodiment of the present invention after coupling.

[0062] Referring to Figures 7 to 9, the series of steps involved in the coupling of the connector inspection device 1 to the connector C can be described as follows: Since each corner of the fourth body portion 13 is formed at an angle, the insertion path of the fourth body portion 13 can be adjusted more flexibly during the process of inserting the fourth body portion 13 into the connector C. In this case, the inclined surfaces of each corner of the connecting portion 131 can be formed such that the connecting portion 131 narrows along the connection direction.

[0063] The fourth body portion 13 can move a predetermined distance in the Y-axis or Z-axis direction, and the integrally connected second body portion 11 and third body portion 12 can also move a predetermined distance in the Y-axis or Z-axis direction.

[0064] Due to the corner structure of the fourth body section 13 and the movable structure of the second body section 11 to the fourth body section 13, the connector inspection device 1 can adjust the connection position and connect to the connector C along a pre-designed connection path. Therefore, the connector inspection device 1 can improve inspection quality and prevent problems with incorrect inspection by more precisely connecting to the connector C.

[0065] Next, as the connector inspection device 1 comes into contact with and is inserted into the connector C, the fourth body portion 13 is subjected to an external force by the connector C and pushed in the opposite direction to the connection direction. The fourth body portion 13, pushed by the connector C, compresses the compression member 122 and can then tightly adhere to the third body portion 12.

[0066] In this case, the detection member 121, which was located inside the fourth body portion 13, is formed to protrude outside the fourth body portion 13, thereby being exposed to the outside and able to come into contact with the circuit inside the connector C and be electrically connected.

[0067] With this protruding structure of the detection member 121, the detection member 121 is designed to protrude outward only when the fourth body portion 13 is properly connected to the connector C along the connection path, with the detection member 121 positioned inside the fourth body portion 13 before connection. This prevents the detection member 121 from being damaged during the connection process.

[0068] A connector inspection device according to another embodiment of the present invention may include only one of the following structures: a structure in which the second to fourth body portions are movable in the Y-axis or Z-axis direction, or a structure in which the fourth body portion is movable toward the third body portion. In other words, a connector inspection device according to another embodiment of the present invention can be designed utilizing only one of the two structures, depending on the structure and process conditions of the battery module, etc.

[0069] The above description is merely illustrative of the technical concept of the present invention, and any person with ordinary skill in the art to which the present invention belongs can make various modifications and alterations without departing from the essential characteristics of the present invention.

[0070] Therefore, the embodiments disclosed in this invention are for illustrative purposes only and not to limit the technical concept of the invention, and the scope of the technical concept of the invention is not limited by such embodiments.

[0071] The scope of protection of this invention must be interpreted in accordance with the claims described below, and all technical concepts within an equivalent scope should be interpreted as being included within the scope of rights of this invention. [Explanation of Symbols]
