[0071] The first circuit penetration portion (142) may be formed to penetrate the upper and lower surfaces of the first circuit board (141). The first circuit penetration portion (142) is formed at a position corresponding to the rotational center axis of the recoil unit (130), and the rotational axis portion (115) formed in the case (100) may penetrate. Accordingly, the first circuit member (140) may rotate on the same center axis as the recoil unit (130).

[0072] The first circuit coil (145) may be formed on one or both sides of the first circuit board (141). The first circuit coil (145) may be formed spirally on one side of the first circuit board (141) with the first circuit through-hole (142) as the center, and connected to the other side through vias to form a continuous coil pattern. Accordingly, sufficient inductive power can be secured even within a limited area.

[0073] An unillustrated cable terminal portion may be electrically connected to the power line or signal line of the security cable (180). The first circuit member (140) may transmit power induced from the second circuit member (150) to the security unit (300) or device side through the security cable (180). Additionally, a status signal or a separation detection signal of the security unit (300) may be transmitted to the second circuit member (150) side through the cable terminal portion.

[0074] The second circuit member (150) is fixedly positioned inside the case (100) and is positioned opposite to the first circuit member (140) while spaced apart from it.

[0075] The second circuit member (150) is connected to the power of the first power cable (11) or the second power cable (12) and can transmit power to the first circuit member (140) in a non-contact manner. In addition, it can receive a signal generated from the security unit (300) and control the speaker (190) through the control assembly (400).

[0076] The second circuit member (150) may include a second circuit board (151), a second circuit through-hole (152) formed at the center of the second circuit board (151), and a second circuit coil (153) formed on the second circuit board (151).

[0077] The second circuit penetration portion (152) may be formed to penetrate the upper and lower surfaces of the second circuit board (151). The second circuit penetration portion (152) is positioned on the same central axis as the first circuit penetration portion (142) and may penetrate the rotation axis portion (115) of the case (100). Accordingly, even when the first circuit member (140) is rotated, the first circuit coil (145) and the second circuit coil (153) can maintain a state facing each other.

[0078] The second circuit coil (153) above can be connected to a circuit pattern or power terminal connected to an external power source.

[0079] When current is applied to the second circuit coil (153), an induced electromotive force may be generated in the first circuit coil (145) by the electromagnetic induction phenomenon, and power may be transmitted to the first circuit member (140) and the security cable (180).

[0080] The first circuit member (140) and the second circuit member (150) can transmit and receive power and signals even without physical contact.

[0081] The second circuit member (150) may be electrically connected to the control assembly (400). The control assembly (400) receives a separation detection signal or a cutting detection signal transmitted from the security unit (300), and

[0082] When an abnormal situation is detected, the speaker (190) can be activated to generate an alarm sound. Accordingly, there is a feature that allows independent security functions to be performed within the case (100) itself without a separate external controller.

[0083] One end of the security cable (180) is fixed to the recoil unit (130), and the other end is pulled out to the outside of the case (100) and can be connected to the security unit (300).

[0084] The above security cable (180) can be wound or withdrawn according to the rotation of the recoil unit (130), and can be automatically wound by the restoring force of the elastic member (133).

[0085] The above security cable (180) may be formed as a composite cable including a power line and a signal line, and may be electrically connected to a security unit (300), a control assembly (400), and a speaker (190).

[0086] The second circuit board (151) includes a coil board section (151a) on which the second circuit coil (153) is placed, a control board section (151c) connected to the control assembly (400), and a connection board section (151b) connecting the coil board section (151a) and the control board section (151c).

[0087] The above coil substrate part (151a) is formed in a disc shape.

[0088] The second circuit penetration part (152) is formed at the planar center of the coil substrate part (151a).

[0089] The above control board (151c) is positioned on the side of the power cable (10) and is electrically connected to the first power cable (11) and the second power cable (12).

[0090] In this embodiment, the first power cable (11) and the second power cable (12) are USB-C type.

[0091] The first power cable (11) includes a first-1 terminal (11a) and a first-2 terminal (11b), and a first power cable section (11c) connecting the first-1 terminal (11a) and the first-2 terminal (11b).

[0092] The second power cable (12) includes a second-1 terminal (12a) and a second-2 terminal (12b), and a second power cable section (12c) connecting the second-1 terminal (12a) and the second-2 terminal (12b).

[0093] The first-2 terminal (11b) and the second-2 terminal (12b) are inserted into and supported by the first power cable groove (122a) and the second power cable groove (122b), and the first-2 terminal (11b) and the second-2 terminal (12b) are electrically connected to the control board portion (151c).

[0094] Either the first power cable (11) or the second power cable (12) provides power to the security unit (300), and in this embodiment, the second power cable (12) provides power to the security unit (300).

[0095] Since the operation of the security unit (300) stops when the second power cable (12) is disconnected, in order to prevent this, the present embodiment has a feature of preventing the second power cable (12) from being unintentionally disconnected from the case (100).

[0096] The above case (100) further includes a cable fixing part (160) protruding forward from the front of the lower case (120), and a cable fixing member (170) that fixes the power cable (10) and the cable fixing part (160).

[0097] The above cable fixing part (160) protrudes below the second-2 terminal (12b).

[0098] The above cable fixing part (160) further includes a cable fixing hole (161) through which the above cable fixing member (170) passes.

[0099] A bolt is used for the cable fixing member (170). The cable fixing member (170) passes through the cable fixing hole (161) and is fastened to the second terminal (12b).

[0100] The power cable (10) can be prevented from being unintentionally disconnected through the above cable fixing member (170) and cable fixing part (160), and has the feature of ensuring operational reliability.

[0101] The control assembly (400) comprises: an operation button (410) that is partially exposed outside the case (100), connected to or in contact with the second circuit board (151), and generates an electrical signal by receiving a user's operation signal; a contact member (420) that is in contact with the second circuit board (151) and generates an electrical signal; a button guide (450) that is positioned inside the case (100) and through which the operation button (410) and the contact member (420) pass; a button terminal (430) that is positioned on the second circuit board (151) and generates an electrical signal by being in contact with the operation button (410); and a contact terminal (440) that is positioned on the second circuit board (151) and generates an electrical signal by being in contact with the contact member (420).

[0102] The above button terminal (430) and contact terminal (440) are fixed to the bottom surface of the control board part (151c).

[0103] When the button terminal (430) is physically in contact with the operation button (410), it generates an electrical signal (ON signal), and when the button terminal (430) is separated from the operation button (410), it generates an electrical OFF signal. A tact switch may be used for the button terminal (430).

[0104] When the contact terminal (440) is physically in contact with the contact member (420), it generates an electrical signal (ON signal), and when the contact terminal (440) is separated from the contact member (420), it generates an electrical OFF signal.

[0105] An electrical signal is generated through physical contact between the contact terminal (440) and the contact member (420), thereby activating the case security function of the control assembly (400).

[0106] When the above contact terminal (440) and contact member (420) are separated, it is determined that there is an intention to disassemble the recoiler (1), and an alarm is output through the speaker (190).

[0107] The lower end of the above-mentioned operation button (410) penetrates the above-mentioned operation button hole (125) and is exposed to the bottom surface of the above-mentioned case (100), and the lower end of the above-mentioned contact member (420) penetrates the above-mentioned contact member hole (126) and is exposed to the bottom surface of the above-mentioned case (100).

[0108] The lower end of the operating button (410) and the lower end of the contact member (420) are positioned within the height of the button groove (127) of the lower case (120), thereby preventing them from protruding downward from the bottom surface of the lower case (120).

[0109] When the above-mentioned operation button (410) is pressed, the lower end of the above-mentioned operation button (410) can form a plane continuous with the bottom surface of the above-mentioned button groove (127).

[0110] The above-mentioned operation button (410) includes an operation button part (411) that contacts the button terminal (430), and an operation head part (412) that is connected to the operation button part (411) and exposed to the outside through the operation button hole (125).

[0111] The above button guide (450) is formed on the upper part of the operation button hole (125) and further includes a button stopper groove (455) that restricts the up and down movement of the operation button (410).

[0112] The above button stopper groove (455) is formed concavely from the lower side to the upper side.

[0113] The above-mentioned operating button (410) is formed between the operating button part (411) and the operating head part (412) and includes an operating button flange (415) that forms a mutual locking with the button stopper groove (455) in the upward direction.

[0114] The above-mentioned operating button flange (415) is formed with an outer diameter larger than that of the above-mentioned operating head part (412).

[0115] The above contact member (420) includes a contact body (421) that protrudes upward from the button guide (450) and contacts the contact terminal (440) when the lower case (120) and upper case (110) are assembled, and a contact head (422) that protrudes downward through the button guide (450) of the contact body (421).

[0116] The above contact head (422) is inserted into the above contact member hole (126) and fixed in place.

[0117] A contact electrode (425) is disposed inside the contact body (421), and the contact electrode (425) is physically in contact with the contact terminal (440) to generate an electrical signal.

[0118] The button guide (450) overlaps with the first power cable (11) and the second power cable (12) when viewed from the bottom. Since the button guide (450) is positioned to overlap with the first power cable (11) and the second power cable (12), the installation space can be minimized, and thereby the volume of the case (100) can be minimized.

[0119] Since the button guide (450) overlaps with the inserted terminals of the first power cable (11) and the second power cable (12), interference with the first power cable (11) and the second power cable (12) must be avoided when assembling the button guide (450).

[0120] To this end, the button guide (450) is fixed to the lower base portion (121) of the lower case (120).

[0121] The above control assembly (400) further includes a guide fastening member (460) that fastens and secures the button guide (450) and the lower base part (121).

[0122] The above guide fastening member (460) includes a first guide fastening member (461) and a second guide fastening member (462).

[0123] Since the button guide (450) is positioned to overlap with the first power cable (11) and the second power cable (12), when viewed from the bottom view, the first guide fastening member (461) overlaps with the first power cable (11) and the second guide fastening member (462) overlaps with the second power cable (12).
