Connector pin unfolding device, connector pin unfolding method, and connector pin analysis method

[0001] [Cross-reference with related applications]

[0002] This application claims the benefit of priority to Korean Patent Application No. 10-2023-0174704, filed December 05, 2023, the entire disclosure of which is incorporated herein by reference.

[0003] [Technical Field]

[0004] The present invention relates to unfolding a female connector pin.

[0005] With the technological development and increasing demand for electric vehicles, mobile devices, and other devices, the demand for secondary batteries as an energy source is increasing. Unlike primary batteries, secondary batteries can be recharged and reused after a single use. A secondary battery consists of a cathode and anode. When a metal in the cathode oxidizes, electricity is generated through the movement of electrons released from the metal.

[0006] These secondary batteries can be provided in multiples to form a battery module. When multiple secondary batteries form a battery module, a higher voltage can be generated than the voltage that can be generated by an individual secondary battery. Furthermore, the voltage of each secondary battery can be controlled to have a constant value. To control the secondary battery, a battery management system (BMS) can be provided. The secondary battery is electrically connected to a substrate, and the substrate and the battery management system are electrically connected, so that the battery management system can receive information about the voltage of the secondary battery and control the secondary battery so that the voltage of the secondary battery remains within a constant range.

[0007] A battery management system may be provided on the outside of the battery module. The battery management system may be connected to the battery module by a connector. That is, the battery management system and the battery module may be connected by fastening a male connector pin having a protruding shape and a female connector pin that forms a space to accommodate the male connector pin. More specifically, the female connector pin may be provided with a contact portion protruding toward the space, and when the male connector pin contacts the contact portion, the female connector pin and the male connector pin may be electrically connected.

[0008] Since the contact portion is configured to make contact with the male connector pin, its durability may require analysis. Since the contact portion is provided on the inside of the female connector pin, in order to analyze the contact portion, the female connector pin must be unfolded to expose the contact portion. Alternatively, there are times when the female connector pin needs to be unfolded in addition to analyzing the contact portion. However, because there is no separate device for unfolding the female connector pin, it is difficult to unfold the female connector pin.

[0009] The present invention has been devised to solve the above problems, and the object of the present invention is to provide a device for easily unfolding a female connector pin.

[0010] The technical problems to be achieved in this document are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present disclosure belongs from the description below.

[0065] Example 1

[0066] Fig. 1 is a perspective view of a battery module (BM) according to a first embodiment of the present invention. Fig. 2 is a perspective view showing a female connector pin (FCP) and a male connector pin (MCP) of the connector (C) pins shown in Fig. 1.

[0067] Referring to FIGS. 1 and 2, a connector (C) pin according to a first embodiment of the present invention will be described.

[0068] A secondary battery (not shown) may be provided to generate electricity. Multiple secondary batteries may be provided to form a battery module (BM). The multiple secondary batteries included in the battery module (BM) may be connected in series to generate a voltage higher than that generated by a single secondary battery. Accordingly, the battery module (BM) can generate the voltage required for a device requiring electricity.

[0069] It may be desirable for each secondary battery to have a constant voltage while generating electricity. To this end, a battery management system (not shown) configured to control the secondary batteries to keep the voltage of each secondary battery within a certain range may be provided. However, since the battery management system may not be a component of the battery module (BM) but may be provided on the outside of the battery module (BM), it may be necessary to electrically connect the battery management system and the battery module (BM). For this purpose, a connector (C) pin may be provided. More specifically, each of a plurality of secondary batteries may be electrically connected to a substrate, and the substrate and the battery management system may be electrically connected by the connector (C) pin, so that the secondary batteries and the battery management system may be electrically connected. The battery management system may receive an electrical signal from the secondary battery through the connector (C) pin, and control the secondary battery so that the secondary battery has a voltage within a predetermined range based on the received electrical signal.

[0070] At this time, the connector (C) pin can be separated into a part including a female connector pin (FCP) and a part including a male connector pin (MCP), as illustrated in FIG. 2. When moving or assembling the battery module (BM), the connector (C) pin should be separated into two parts to facilitate movement and / or assembly of the battery module (BM). The male connector pin (MCP) includes a protrusion, and the female connector pin (FCP) can form an accommodation space (100S) that accommodates the protrusion of the male connector pin (MCP). The female connector pin (FCP) can include a contact portion (110) protruding toward the accommodation space (100S) on the inside, and the contact portion (110) can be configured to be electrically connected to the female connector pin (FCP) by making contact with the protrusion of the male connector pin (MCP).

[0071] Additionally, in FIGS. 1 and 2, the female connector pin (FCP) is fixed to the battery module (BM) and the male connector pin (MCP) is moved to be connected to the female connector pin (FCP) while being connected to the battery management system, but this is not limited to the configuration in which the male connector pin (MCP) is fixed to the battery module (BM) and is directly connected to the battery management system, and the female connector pin (FCP) may be configured.

[0072] For reference, the female connector pin (FCP) is formed to extend in one direction, and an accommodation space (100S) may be formed inside the female connector pin (FCP) along the extension direction of the female connector pin (FCP). The female connector pin (FCP) has a constant cross-section and may extend in the extension direction. For example, the cross-section of the female connector pin (FCP) may be square. In this case, the female connector pin (FCP) may be formed by folding. However, the present invention is not limited thereto, and the cross-section of the female connector pin (FCP) may be circular. In this case, the female connector pin (FCP) may be formed by bending. For reference, folding may be a concept including bending, and bending may be understood as an example of folding. Furthermore, as illustrated in FIG. 2, the ends of the female connector pin (FCP) may overlap in a direction perpendicular to the longitudinal direction. However, without limitation, the ends of the female connector pins (FCP) may be connected to each other.

[0073] The contact portion (110) of the female connector pin (FCP) is configured to come into contact with the male connector pin (MCP), and thus may need to have high durability in order to perform the function of the connector (C) pin for a long time. Therefore, research may be conducted to increase the durability of the contact portion (110). In order to increase the durability of the contact portion (110), it is necessary to analyze the durability of the contact portion (110). At this time, since the contact portion (110) may be located on the inside of the female connector pin (FCP), the female connector pin (FCP) needs to be unfolded.

[0074] Conventionally, female connector pins (FCPs) were unfolded using tweezers or other similar devices. However, unfolding female connector pins (FCPs) using this method was difficult and time-consuming. The present invention aims to address these issues. Below, a connector pin unfolding device (CUA) according to a first embodiment of the present invention will be further described.

[0075] FIG. 3 is a perspective view illustrating the female connector pin (FCP) illustrated in FIG. 2. FIG. 4 is a conceptual diagram illustrating a connector pin unfolding device (CUA) moving toward the female connector pin (FCP) illustrated in FIG. 3. FIG. 5 is an enlarged perspective view illustrating a first blade portion (211a) being inserted between the first folding portion (101) and the fifth folding portion (105) of the female connector pin (FCP) illustrated in FIG. 4. FIG. 6 is a cross-sectional view illustrating a first blade portion (211a) being inserted between the first folding portion (101) and the fifth folding portion (105) of the female connector pin (FCP) illustrated in FIG. 5, and a second unfolding pliers bar (200b) being moved toward the first unfolding pliers bar (200a). Fig. 7 is an enlarged view showing that the fixed clamp (FC) is fixed to the second folding portion (102) before the unfolding clamp (UC) shown in Fig. 6 unfolds the first folding portion (101). Fig. 8 is a cross-sectional view showing that the first folding portion (101) of the female connector pin (FCP) shown in Fig. 7 is supported by the second unfolding clamp bar (200b) and the second unfolding clamp bar (200b) before unfolding the first folding portion (101). Fig. 9 is an enlarged view showing that the first folding portion (101) of the female connector pin (FCP) shown in Fig. 8 is unfolded. Fig. 10 is a cross-sectional view showing that the fifth folding portion (105) of the female connector pin (FCP) shown in Fig. 9 is unfolded. Fig. 11 is a cross-sectional view illustrating an unfolding projection (230) provided to unfold the third folding portion (103) and the fourth folding portion (104) of the female connector pin (FCP) illustrated in Fig. 10. Fig. 12 is a perspective view illustrating the third folding portion (103) and the fourth folding portion (104) of the female connector pin (FCP) illustrated in Fig. 11 unfolded.

[0076] Referring to FIGS. 3 to 12, a method for deploying a female connector pin (FCP) according to a first embodiment of the present invention will be described. It can be understood that the female connector pin (FCP) is deployed in the order of FIGS. 3 to 12.

[0077] As illustrated in FIG. 3, a female connector pin (FCP) may be formed by folding. The female connector pin (FCP) may be configured to form a receiving space (100S) into which a male connector pin (MCP) can be inserted. More specifically, the female connector pin (FCP) may include a first folding portion (101) forming one end, a second folding portion (102) configured to face the first folding portion (101), a third folding portion (103) connecting the first folding portion (101) and the second folding portion (102), a fourth folding portion (104) configured to face the third folding portion (103), and / or a fifth folding portion (105) forming the other end and configured to overlap the first folding portion (101) in a direction intersecting the longitudinal direction of the first folding portion (101). In other words, the female connector pin (FCP) can be connected in the following order: first folding part (101) - third folding part (103) - second folding part (102) - fourth folding part (104) - fifth folding part (105). At this time, the first folding part (101) can be located outside the fifth folding part (105). The contact part (110) mentioned above can be located on the fifth folding part (105). However, this is merely an example, and the contact part (110) can also be located on the second folding part (102) to the fourth folding part (104). Furthermore, it can be located on an area that does not overlap with the fifth folding part (105) of the first folding part (101).

[0078] Additionally, the first folding portion (101) may be in contact with the fifth folding portion (105). The end of the first folding portion (101) may not extend beyond the fourth folding portion (104).

[0079] First, the structural features of a connector pin unfolding device (CUA) for unfolding a female connector pin (FCP) are described.

[0080] As illustrated in FIG. 4, a connector pin unfolding device (CUA) may be provided to unfold a female connector pin (FCP). The connector pin unfolding device (CUA) may include a unfolding clamp (UC) configured to be fixed to a first folding portion (101). It may include a fixing clamp (FC) configured to support a second folding portion (102).

[0081] As illustrated in FIG. 5, a portion of the unfolding gripper (UC) is accommodated between the first folding portion (101) and the fifth folding portion (105), and as illustrated in FIG. 9, the unfolding gripper (UC) can be configured to unfold the first folding portion (101) by moving away from the fixed gripper (FC), thereby moving at least a portion of the first folding portion (101) away from the second folding portion (102). For reference, since the first folding portion (101) and the fifth folding portion (105) each form an end of a female connector pin (FCP), either the first folding portion (101) or the fifth folding portion (105) needs to be unfolded first. At this time, since the first folding part (101) can be positioned outside the fifth folding part (105), the first folding part (101) can be unfolded before the fifth folding part (105).

[0082] As illustrated in FIG. 4, the deployment forceps (UC) may include a first deployment forceps bar (200a) including a first support portion (210a) configured to support an outer surface of the first folding portion (101), and the deployment forceps (UC) may include a second deployment forceps bar (200b) including a second support portion (210b) configured to support an inner surface opposite to the outer surface of the first folding portion (101). At this time, the first deployment forceps bar (200a) may be coupled to the second deployment forceps bar (200b) so as to be rotatable about a deployment forceps rotation axis (200L). The deployment forceps (UC) may have a structure similar to scissors. It can be understood that the unfolding forceps (UC) have various methods of supporting the first folding portion (101), and as one of the methods, a method in which the first unfolding forceps bar (200a) and the second unfolding forceps bar (200b) each support opposite sides of the first folding portion (101) is introduced as the first embodiment.

[0083] The first deployment forceps bar (200a) may further include a first handle portion (220a) positioned on the opposite side of the first support portion (210a) with respect to the deployment forceps rotation axis (200L). The second deployment forceps bar (200b) may further include a second handle portion (220b) positioned on the opposite side of the second support portion (210b) with respect to the deployment forceps rotation axis (200L). If the deployment forceps (UC) are likened to scissors as described above, the first handle portion (220a) and the second handle portion (220b) may have a configuration corresponding to a grippable handle of scissors, and the first support portion (210a) and the second support portion (210b) may have a configuration corresponding to a portion of scissors that cuts another component. By forming a first handle portion (220a), a second handle portion (220b) and a first support portion (210a), a second support portion (210b), the first support portion (210a) and the second support portion (210b) can be moved by the movement of the first handle portion (220a) and the second handle portion (220b). As illustrated in Fig. 6, the second support portion (210b) is located between the first folding portion (101) and the fifth folding portion (105), making it difficult to move directly. Therefore, the second support portion (210b) can be moved by manipulating the first handle portion (220a) and the second handle portion (220b) located on the outside of the female connector pin (FCP).

[0084] The first support member (210a) and the second support member (210b) may have a length corresponding to the length of the first folding member (101) in order to effectively support the first folding member (101).

[0085] In other words, the first support portion (210a) can extend from the deployment forceps rotation axis (200L). The first handle portion (220a) can extend in a direction different from the extension direction of the first support portion (210a) at a portion adjacent to the deployment forceps rotation axis (200L). The second support portion (210b) and the second handle portion (220b) can correspond to the first support portion (210a) and the second handle portion (220b). Accordingly, the first handle portion (220a) and the second handle portion (220b) can be positioned on opposite sides of the deployment forceps rotation axis (200L) from the first support portion (210a) and the second support portion (210b).

[0086] That is, the first support member (210a) can rotate about the deployment forceps rotation axis (200L) with respect to the second support member (210b) while the first handle member (220a) rotates about the deployment forceps rotation axis (200L) to get closer to the second handle member (220b).

[0087] Furthermore, the first support part (210a) can rotate to come closer to the second support part (210b) while the first handle part (220a) rotates to come closer to the second handle part (220b) around the deployment forceps rotation axis (200L).

[0088] The first support portion (210a) and the second support portion (210b) may further include a first blade portion (211a) and a second blade portion (211b) configured such that the cross-sectional area decreases toward the end. In particular, as illustrated in FIG. 5, the second support portion (210b) needs to be moved to widen the gap between the first folding portion (101) and the fifth folding portion (105), so the second blade portion (211b) may be formed at an end of the second support portion (210b) that faces the gap between the first folding portion (101) and the fifth folding portion (105). With reference to FIG. 5, the second blade portion (211b) may be positioned below the second deployment gripper bar (200b).

[0089] The first blade portion (211a) and the second blade portion (211b) may include a first inclined surface (211Aa) and a second inclined surface (211Ab) that are inclined so as to become closer to the first folding portion (101) as they go toward the end. The first inclined surface (211Aa) and the second inclined surface may be an example of a method for forming the first blade portion (211a) and the second blade portion (211b).

[0090] The fixed forceps (FC) may include a first fixed forceps bar (300a) and a second fixed forceps bar (300b) that is rotatably coupled to the first fixed forceps bar (300a) about a fixed forceps rotation axis (300L). At this time, the first fixed forceps bar (300a) may include a first fixed portion (310a) configured to support an outer surface of the second folding portion (102), and the first fixed forceps bar (300a) may include a first fixed forceps handle portion (320a) that is positioned on an opposite side of the first fixed portion (310a) about the fixed forceps rotation axis (300L). The second fixed gripper bar (300b) may include a second fixed portion (310b) configured to support an inner surface opposite to an outer surface of the second folding portion (102), and the second fixed gripper bar (300b) may include a second fixed gripper handle portion (320b) positioned on an opposite side of the second fixed portion (310b) with respect to the fixed gripper rotation axis (300L). The first fixed portion (310a) may be configured to rotate away from the second fixed portion (310b) while the first fixed gripper handle portion (320a) rotates about the fixed gripper rotation axis (300L) toward the second fixed gripper handle portion (320b). The fixed gripper (FC) may have an operating principle similar to that of a clothespin.

[0091] The fixed gripper (FC) may be shorter than the deployable gripper (UC). Since the deployable gripper (UC) must apply force across the entire first folding portion (101), it needs to have a length corresponding to the length of the first folding portion (101) in order to evenly press the entire first folding portion (101). However, since the fixed gripper (FC) only needs to be fixed to the second folding portion (102), it can function even if its length is short. Furthermore, when the fixed gripper (FC) is short, the distance that the fixed gripper (FC) moves for fixing is shortened, so the time for fixing the fixed gripper (FC) to the second folding portion (102) can be reduced.

[0092] A connector pin unfolding device (CUA) connects a deployable gripper (UC) and a fixed gripper (FC), and may further include a deformable connector (400). The length of the connector (400) may be deformable. As illustrated in FIG. 4, the distance between the fixed gripper (FC) and the deployable gripper (UC) may correspond to the width of the female connector pin (FCP). Since the width of the female connector pin (FCP) may vary depending on the device, the distance between the fixed gripper (FC) and the deployable gripper (UC) may be adjusted by changing the length of the connector (400). Furthermore, as illustrated in FIG. 9, while the deployable gripper (UC) moves away from the fixed gripper (FC), the connector (400) may be deformed to increase in length.

[0093] The connector (400) is divided into two components and its length can be increased or decreased in the same way as a rail moves.

[0094] As illustrated in FIG. 6, the deployment gripper (UC) may include an elastic body (240) positioned on the deployment gripper rotation axis (200L) so that the first support portion (210a) is elastically biased toward the second support portion (210b). Even if no force is applied to the deployment gripper (UC) by the elastic body (240), the deployment gripper (UC) can support the first folding portion (101), etc. Furthermore, as described below, when the deployment gripper (UC) needs to strongly grip the first folding portion (101), etc., the elastic body (240) may be helpful for this.

[0095] The connector pin unfolding device (CUA) may include a protruding unfolding protrusion (230). More preferably, the first deployable gripper bar (200a) may further include an unfolding protrusion (230) configured to protrude in an opposite direction from the first support portion (210a) toward the first folding portion (101). Since the first deployable gripper bar (200a) is configured to support the outer surface of the first folding portion (101), even if the unfolding protrusion (230) is formed, the function of the connector pin unfolding device (CUA) may not be hindered. The unfolding protrusion (230) may pressurize the female connector pin (FCP), as described below, as illustrated in FIG. 11, to unfold the female connector pin (FCP).

[0096] The unfolding protrusion (230) may have a cross-section that is a portion of a circle. Accordingly, the possibility of the female connector pin (FCP) being damaged while the unfolding protrusion (230) presses the female connector pin (FCP) may be reduced. Furthermore, if the unfolding protrusion (230) has a shape that is a portion of a sphere, the unfolding protrusion (230) can be moved to a position for unfolding the female connector pin (FCP) even when it is roughly aligned with the female connector pin (FCP).

[0097] As described below, the unfolding protrusion (230) may be configured to unfold the third folding portion (103) by moving toward the second folding portion (102) while in contact with the third folding portion (103) connecting the first folding portion (101) and the second folding portion (102) after the first folding portion (101) is unfolded. More specifically, the unfolding protrusion (230) may have a width greater than the width of the second folding portion (102) so as to unfold the third folding portion (103) and the fourth folding portion (104) extending from the opposite side of the third folding portion (103) with respect to the second folding portion (102) together. This will be further described in detail below.

[0098] Below, the process of unfolding a female connector pin (FCP) by a connector pin unfolding device (CUA) is described.

[0099] First, the first folding section (101) can be supported by the unfolding forceps (UC).

[0100] As illustrated in FIG. 4, the connector pin unfolding device (CUA) can be moved toward the female connector pin (FCP). At this time, by adjusting the length of the connector (400), the unfolding gripper (UC) can be positioned to correspond to the first folding section (101) and the fixing gripper (FC) can be positioned to correspond to the second folding section (102).

[0101] As illustrated in FIG. 5, the second blade portion (211b) can be moved between the first folding portion (101) and the fifth folding portion (105). At this time, since the tip of the blade portion is sharp, it can be easy to penetrate between the first folding portion (101) and the fifth folding portion (105). If the second blade portion (211b) comes into contact with the first blade portion (211a), the movement of the second blade portion (211b) between the first folding portion (101) and the fifth folding portion (105) may be impeded, so that the user can move the first handle portion (220a) and the second handle portion (220b) away from each other so that the first blade portion (211a) is spaced apart from the second blade portion (211b). At this time, the elastic body (240) can apply elastic force in the direction in which the first deployment force bar (200a) and the second deployment force bar (200b) come closer, so the user can apply force that overcomes the elastic force.

[0102] After the second support portion (210b) is moved between the first folding portion (101) and the fifth folding portion (105) by the second blade portion (211b), the first handle portion (220a) is rotated toward the second handle portion (220b), so that the first support portion (210a) can be moved toward the outer surface of the first folding portion (101). Accordingly, the first support portion (210a) can support the inner surface of the first folding portion (101), and the second support portion (210b) can support the outer surface of the first folding portion (101). In this process, the user may apply force to the first handle portion (220a) in the direction of the second handle portion (220b), but even if the user does not apply any force, the first handle portion (220a) may come closer to the second handle portion (220b) and the first support portion (210a) may come closer to the second support portion (210b) due to the elastic force of the elastic body (240).

[0103] Additionally, although the length of the second support member (210b) is shown in FIG. 6 as being shorter than the length of the first folding member (101), the length of the second support member (210b) may be provided to be longer than the length of the first folding member (101).

[0104] After supporting the first folding part (101) through the above process with the unfolding forceps (UC), the fixed forceps (FC) can be fixed to the second folding part (102). However, the fixed forceps (FC) are fixed to the second folding part (102) only because the second folding part (102) is located on the opposite side of the first folding part (101) and is positioned in a part that is easy to fix, and it may be fixed to a part of a female connector pin (FCP) other than the second folding part (102). In the following, for the convenience of explanation, it is assumed that the fixed forceps (FC) are fixed to the second folding part (102).

[0105] As illustrated in Fig. 7, when the second fixed forceps handle portion (320b) is pressed toward the first fixed forceps handle portion (320a), the first fixed forceps (310a) can be moved away from the second fixed forceps (310b). When the first fixed forceps (310a) and the second fixed forceps (310b) are moved away from each other, the fixed forceps (FC) can be moved so that the second folding portion (102) is accommodated in the space between the first fixed forceps (310a) and the second fixed forceps (310b). At this time, since the elastic body (240) is still provided in the fixed tongs (FC), and an elastic force is applied in the direction in which the first fixed part (310a) and the second fixed part (310b) come closer, while the first fixed part (310a) and the second fixed part (310b) are positioned in the second folding part (102), the user can press the first fixed tongs handle part (320a) so that the first fixed tongs handle part (320a) comes closer to the second fixed tongs handle part (320b).

[0106] When the second folding part (102) is positioned between the first fixing part (310a) and the second fixing part (310b), the user can release the force applied to the first fixing forceps handle part (320a) and the second fixing forceps handle part (320b), thereby bringing the first fixing part (310a) and the second fixing part (310b) closer. Due to the elastic force of the elastic body (240), the first fixing part (310a) and the second fixing part (310b) can tightly grip the second folding part (102), and accordingly, the fixing forceps (FC) can be fixed to the second folding part (102).

[0107] Thereafter, as illustrated in Fig. 8, the first handle portion (220a) and the second handle portion (220b) of the unfolding forceps (UC) can be pressed in a direction toward each other so that the first support portion (210a) and the second support portion (210b) can firmly grip the first folding portion (101). That is, the first folding portion (101) can be supported by the unfolding forceps (UC).

[0108] For reference, the structure in which the unfolding gripper (UC) is connected to the fixed gripper (FC) may be different. This may be because the unfolding gripper (UC) is configured to apply force to strongly support the first folding portion (101). It may be easier to apply force by bringing the first handle portion (220a) and the second handle portion (220b) closer together rather than farther apart. On the other hand, since the fixed gripper (FC) needs to apply force to move the first fixing portion (310a) and the second fixing portion (310b) apart while initially moving to be fixed to the second folding portion (102), it may be necessary to configure the first fixing portion (310a) and the second fixing portion (310b) to move apart in the direction in which the first fixing gripper handle portion (320a) and the second fixing gripper handle portion (320b), which are easy to apply force to, move closer together.

[0109] Thereafter, as illustrated in FIG. 9, by moving the unfolding gripper (UC) away from the fixed gripper (FC), at least a portion of the first folding portion (101) can be moved away from the second folding portion (102). The first folding portion (101) can be folded in a different direction from the third folding portion (103). The first folding portion (101) and the third folding portion (103) can have the same extension direction through a process described below, and at this stage, for the convenience of future processes, the extension direction of the first folding portion (101) with respect to the third folding portion (103) can be different.

[0110] After the unfolding of the first folding part (101) is completed, the unfolding of the fifth folding part (105) can be performed.

[0111] As illustrated in FIG. 10, the deploying gripper (UC) may be configured to deploy the fifth folding portion (105) by moving at least a portion of the fifth folding portion (105) away from the second folding portion (102) after deploying the first folding portion (101). The fixed gripper (FC) may still be fixed to the second folding portion (102) as in the previous step. Only the deploying gripper (UC) may be separated from the first folding portion (101) and moved to support the fifth folding portion (105). Moving the fifth folding portion (105) to the deploying gripper (UC) may be similar to the case of the first folding portion (101). The fifth folding part (105) can also be moved to the outside of the receiving space (100S) so as to have an extension direction different from the extension direction of the fourth folding part (104) with respect to the fourth folding part (104).

[0112] Thereafter, as illustrated in FIG. 11, the female connector pin (FCP) with the first folding portion (101) and the fifth folding portion (105) unfolded to a certain extent can be placed on the bottom surface with the second folding portion (102) in contact. The unfolding protrusion (230) can be positioned to contact the third folding portion (103) and the fourth folding portion (104). A plurality of unfolding protrusions (230) can be positioned to contact the third folding portion (103) and the fourth folding portion (104) with respect to the longitudinal direction of the third folding portion (103) and the fourth folding portion (104), respectively. In this case, the first unfolding gripper bar (200a) can be positioned to face the second folding portion (102).

[0113] When the unfolding protrusion (230) is aligned as above, the unfolding protrusion (230) can be moved toward the second folding portion (102). As the unfolding protrusion (230) is moved, the third folding portion (103) and the fourth folding portion (104) can be moved to the outside of the receiving space (100S). With reference to Fig. 11, the third folding portion (103) and the fourth folding portion (104) can be moved to the left and right, respectively.

[0114] Thereafter, the female connector pin (FCP) can be unfolded by applying an impact between the first folding part (101) and the second folding part (102) and / or between the second folding part (102) and the third folding part (103) and / or between the third folding part (103) and the fourth folding part (104) and / or between the fourth folding part (104) and the fifth folding part (105) using the unfolding protrusion (230).

[0115] As a result, the female connector pin (FCP) can be unfolded to expose the contact portion (110), as illustrated in FIG. 12.

[0116] After the female connector pin (FCP) is deployed, the degree to which the surface plating layer of the contact portion (110) has been peeled off can be analyzed. Methods for analyzing the contact portion (110) can include, for example, SEM, EDS, FIB, etc.

[0117] Below, embodiments different from the first embodiment are described. Commonalities with the first embodiment will be omitted as much as possible, and the other embodiments will be described focusing on differences. In other words, it should be clear that any details not described in the other embodiments can be supplemented by the first embodiment.

[0118] Second Example

[0119] FIG. 13 is a cross-sectional view illustrating a female connector pin (FCP) and a connector pin unfolding device (CUA) according to a second embodiment of the present invention.

[0120] Referring to FIG. 13, a deployment forceps (UC) according to a second embodiment of the present invention is described.

[0121] The second embodiment differs from the first embodiment in that the blade portion of the unfolding forceps (UC) is formed at a different location from the location where the blade portion of the first embodiment is formed.

[0122] The first deployable forceps bar (200a) may include a first sub-blade portion (211d-1) at an end in the extension direction. The first sub-blade portion (211d-1) may be configured to have a cross-sectional area that decreases toward the end. The second deployable forceps bar (200b) may include a second sub-blade portion (211c-1) at an end in the extension direction. The second sub-blade portion (211c-1) may be configured to have a cross-sectional area that decreases toward the end. The first deployable forceps bar (200a) may need to widen the gap formed between the first folding portion (101) and the fifth folding portion (105) as it descends, but may also need to widen the gap formed between the first folding portion (101) and the fifth folding portion (105) as it advances. A first blade portion (211a) may be provided for lowering the first deployment gripper bar (200a), and a first sub-blade portion (211d-1) may be provided for advancing the first deployment gripper bar (200a).

[0123] Third Example

[0124] FIG. 14 is a cross-sectional view illustrating a female connector pin (FCP) and a connector pin unfolding device (CUA) according to a third embodiment of the present invention.

[0125] Referring to FIG. 14, a connector pin unfolding device (CUA) according to a third embodiment of the present invention is described.

[0126] The third embodiment differs from the first embodiment in that the operation of the unfolding gripper (UC) and the fixed gripper (FC) are opposite to each other.

[0127] As the first handle portion (220a-2) approaches the second handle portion (220b-2), the first support portion (210a-2) can move away from the second support portion (210b-2). As the first fixed tong handle portion (320a-2) approaches the second fixed tong handle portion (320b-2), the first fixed portion (310a-2) can move closer to the second fixed portion (310b-2). With this structure, the user can strengthen the fixing force of the fixed tongs (FC).

[0128] Example 4

[0129] FIG. 15 is a cross-sectional view illustrating a female connector pin (FCP) and a connector pin unfolding device (CUA) according to a fourth embodiment of the present invention.

[0130] Referring to FIG. 15, an unfolding protrusion (230-3) according to a fourth embodiment of the present invention is described.

[0131] The fourth embodiment differs from the first embodiment in that the shape of the unfolding protrusion (230-3) is different.

[0132] The unfolding protrusion (230-3) in the fourth embodiment may have a triangular cross-section. The base of the triangle may be positioned on the first support member (210a), and the vertex facing the base may face the second folding member (102). The side edges of the unfolding protrusion (230-3) may contact the third folding member (103) and / or the fourth folding member (104), respectively, and by pressing the unfolding protrusion (230), the third folding member (103) and / or the fourth folding member (104) may be unfolded.

[0133] Example 5

[0134] FIG. 16 is a cross-sectional view illustrating a female connector pin (FCP) and a connector pin unfolding device (CUA) according to a fifth embodiment of the present invention.

[0135] Referring to FIG. 16, an unfolding protrusion (230-4) according to a fifth embodiment of the present invention is described.

[0136] The fifth embodiment differs from the first embodiment in that the unfolding protrusion (230-4) is configured to press only one of the third folding portion (103) or the fourth folding portion (104).

[0137] Therefore, the width of the unfolding protrusion (230-4) in the fifth embodiment need not be greater than the distance between the third folding portion (103) and the fourth folding portion (104).

[0138] Example 6

[0139] FIG. 17 is a cross-sectional view illustrating a female connector pin (FCP) and a connector pin unfolding device (CUA) according to a sixth embodiment of the present invention.

[0140] Referring to FIG. 17, a fixed gripper (FC) according to a sixth embodiment of the present invention is described.

[0141] The sixth embodiment differs from the first embodiment in that the length of the fixed forceps (FC) is different.

[0142] The length of the fixed clamp (FC) may correspond to the length of the unfolding clamp (UC). As a result, the fixed clamp (FC) may be stably fixed to the second folding member (102). In other words, the lengths of the first fixed member (310a-5) and the second fixed member (310b-5) may correspond to the lengths of the first support member (210a) and the second support member (210b).

[0143] Unless explicitly stated otherwise, the embodiments described above may be combined with other embodiments. Alternatively, combinations between embodiments may be considered possible, unless one embodiment is explicitly restricted from being combined with another embodiment. Combinations of one embodiment with another embodiment are deemed to be disclosed in this document.

[0144] Although the present invention has been described above with reference to limited embodiments and drawings, the present invention is not limited thereto, and various embodiments are possible within the scope equivalent to the technical idea of ​​the present invention and the patent claims to be described below by a person having ordinary skill in the art to which the present invention pertains.
