However, this is for the convenience of explaining the invention, and the direction may be different in actual use.

[0024] Referring to FIGS. 1 to 6, a vehicle charging outlet (10) connected to a charging unit (20) of an electric vehicle according to one embodiment of the present invention comprises a main housing (100) having an internal receiving space (130) and a charging connection unit (200) installed in the receiving space (130) and exposed to one side of the main housing (100). The charging connection unit (200) comprises a charging housing (220) formed by an outlet terminal (211) that relays an electrical connection, a terminal unit (210) formed by a cable (212) connected to the outlet terminal (211), an assembly body (221) that accommodates the connection portion between the outlet terminal (211) and the cable (212), and a coupling body (222) coupled to one side of the assembly body (221) that accommodates the electrical connection relay portion of the outlet terminal (211). It is characterized by being formed as a fire extinguishing pad (230) installed on the inside or outside of the charging housing (220) and generating fire extinguishing gas when the terminal part (210) overheats.

[0025] The charging outlet (10) is connected to an external power source and coupled to the charging part (20) of the electric vehicle, thereby transferring electrical energy from the external power source to the electric vehicle to charge the battery.

[0026] To this end, the charging section (20) of the electric vehicle is formed with a charging inlet bracket (21) that is exposed on one side of the vehicle body and provides a structure to which a charging outlet (10) is connected, a communication space (22) that passes through the charging inlet bracket (21) and communicates with a relay space (22241) when connected to a charging outlet (10), and an inlet terminal (23) that is electrically connected to a battery on one side and placed in the communication space (22).

[0027] In summary, when a charging outlet (10) is connected to a charging unit (20) of an electric vehicle, a second connecting extension part (2223) is complementarily connected to a charging inlet bracket (21), thereby connecting the relay space (22241) and the communication space (22). Accordingly, the relay part (2112) of the outlet terminal (211) and the inlet terminal (23) come into contact and are electrically connected to form a closed circuit.

[0028] To this end, the charging outlet (10) is formed with an inner receiving space (130), a main housing (100) that forms the outer shape, and a charging connection part (200) installed in the receiving space (130) that relays an electrical connection.

[0029] Specifically, the main housing (100) is formed by first and second housings joined in an intersecting direction, and is formed with a receiving space (130) that accommodates a part of the charging connection part (200) inwardly according to the joining of the first and second housings, and an opening hole (140) formed by opening one side of the receiving space (130) so that a part of the charging connection part (200) is exposed outwardly.

[0030] Accordingly, the main housing (100) accommodates an outlet terminal (211) that relays an electrical connection to the inside and protects it from the outside, while simultaneously guiding and aligning the cable (212) in one direction.

[0031] In addition, a connecting body (222) that is connected to the charging part (20) of an electric vehicle through an open hole (140) is positioned outside the receiving space (130).

[0032] The charging connection part (200) is formed with a terminal part (210) that relays an electrical connection, a charging housing (220) that accommodates a part of the terminal part (210) inside the receiving space (130) and accommodates a part of the terminal outside the receiving space (130), and a fire extinguishing pad (230) that generates fire extinguishing gas when the terminal part (210) overheats.

[0033] Specifically, the terminal section (210) is formed by an outlet terminal (211) that relays an electrical connection and a cable (212) connected to the outlet terminal (211) and connected to an external power source, and supplies power through contact with an inlet terminal (23) installed in the charging section (20) of the electric vehicle.

[0034] At this time, it is preferable to further form a terminal sealing (213) on the outer side of the outlet terminal (211) to prevent foreign substances such as moisture from entering the assembly space (22121) that accommodates the part where the terminal part (210) and the cable (212) are connected.

[0035] Additionally, the outlet terminal (211) is formed with a connecting part (2111) at one end that is electrically connected by being crimped with the internal wire of the cable (212), and a relay part (2112) connected to the other end of the connecting part (2111) and in contact with the inlet terminal (23).

[0036] At this time, the connecting part (2111) and the relay part (2112) are connected through a fastening member to form a single terminal, so that only the relay part (2112) can be replaced as needed. In addition, the replacement process can be performed by separating only the connecting body (222) without separating the assembly body (221) installed inside the receiving space (130), thereby significantly improving the workability of the replacement.

[0037] In addition, the charging outlet (10) of the present invention uses a plurality (2) of connection parts (2111) to more safely transmit high voltage, wherein only one of the plurality of connection parts (2111) is connected to a relay part (2112), and the plurality of connection parts (2111) are connected by a connection bus bar (2113) to form a single electrode.

[0038] To summarize, a pair of outlet terminals (211) are formed by two connection parts (2111), a connection bus bar (2113) that electrically integrates the two connection parts (2111), and a relay part (2112) connected to one of the connection parts (2111), thereby forming different electrodes.

[0039] Accordingly, when the charging outlet (10) is connected to the charging part (20) of the electric vehicle, different electrodes are connected to the inlet terminal (23) to form a closed circuit.

[0040] The charging housing (220) accommodates the terminal portion (210) to protect it from the outside, while simultaneously guiding the position of the outlet terminal (211) and sealing the electrical connection portion to enable safer charging.

[0041] To this end, the charging housing (220) is formed with an assembly body (221) that accommodates the connection portion of the outlet terminal (211) and the cable (212), and a coupling body (222) that is coupled to one side of the assembly body (221) and accommodates the electrical connection relay portion of the outlet terminal (211).

[0042] Specifically, the assembly body (221) is formed by an assembly plate (2211) that is positioned to be exposed on one side of the open hole (140) and closes the receiving space (130), an extension part (2212) that extends from the other side of the assembly plate (2211) into the receiving space (130) to form an open assembly space (22121), a receiving body (2213) that accommodates the connecting part (2111), and an assembly sealing (2214) that closes the assembly space (22121).

[0043] At this time, the assembly space (22121) formed by the extension part (2212) is formed by being partitioned in an intersecting direction so that the connecting parts (2111) forming different electrodes do not come into contact. Accordingly, the receiving body (2213) is also formed in pairs so that a plurality of connecting parts (2111) constituting a single electrode are separated and accommodated, and assembly holes (22131) are formed at regular intervals so that the plurality of connecting parts (2111) do not come into contact at any position.

[0044] Additionally, the assembly body (221) further has a first seating portion (22132) on which the first pad (231) is seated, corresponding to the position of the part where the connecting portion (2111) and the cable (212) are compressed and connected.

[0045] At this time, the first mounting portion (22132) is formed so that the first pad (231) does not come into contact with the connecting portion (2111) in order to prevent the generation of fire extinguishing gas due to instantaneous overheating of the terminal or an acceptable heating state.

[0046] Accordingly, the first mounting portion (22132) of one example is formed by being recessed outward from the receiving body (2213), but it is preferable that a first sensing hole (22133) is further formed through the first mounting portion (22132) to respond more accurately to the overheating state of the connecting portion (2111), that is, the temperature of the air around the connecting portion (2111).

[0047] However, depending on the design, the first seating portion (22132) may be formed by being recessed into the inner surface of the assembly hole (22131) of the receiving body (2213), in which case the first sensing hole (22133) is not required.

[0048] Additionally, a pair of assembly seals (2214) are formed and installed at the rear of the extension direction of each receiving body (2213), ultimately sealing the assembly space (22121) that is open to one side. Accordingly, the entry of foreign substances, such as moisture, from the outside into the part where the connecting part (2111) and the cable (212) are compressed and connected is blocked.

[0049] In summary, the first mounting portion (22132) of the present invention can be formed at any location where the first pad (231) can provide fire extinguishing gas to the assembly space (22121) in response to the air temperature around the connection portion (2111) and the cable (212), and depending on the location of the first mounting portion (22132), a configuration such as the first detection hole (22133) may be added.

[0050] At this time, even when the receiving body (2213) is configured to be received inside the assembly space (22121) and the first sensing hole (22133) is formed, the problem of reduced sealing force in the connection part (2111) and the cable (212) compression part does not occur.

[0051] Additionally, the assembly body (221) is further formed with an assembly holder (2215) installed at the rear of the extension direction of the extension part (2212) to press the assembly sealing (2214) and guide the position of the cable (212) connected to the plurality of connection parts (2111), and a close sealing (2216) installed to surround the outer surface of the relay part (2112) on one side of the assembly plate (2211).

[0052] Here, it is preferable that the assembly holder (2215) be formed by being separated into a holder positioned between cables (212) forming different poles to more easily guide the multiple cables (212) and facilitate assembly, and a holder positioned to wrap around the entire outer surface of the multiple cables (212).

[0053] Additionally, the sealing (2216) is formed to surround the relay part (2112) on one side of the assembly plate (2211) which is placed at the joint portion of the assembly body (221) and the joint body (222), thereby blocking moisture or the like entering through the joint portion from moving to the outlet terminal (211) where the electrical connection is made.

[0054] To this end, the sealing seal (2216) is formed to protrude a predetermined distance forward in the extension direction while installed on one side of the assembly plate (2211), and is pressed according to the connection of the coupling body (222) to secure a sealing force.

[0055] The coupling body (222) is formed by a coupling plate (2221) coupled to one side of the assembly plate (2211), and first and second coupling extension parts (2222, 2223) that extend forward in the direction of extension of the coupling plate (2221) and are inserted into the charging part (20) of the electric vehicle.

[0056] Here, the first coupling extension part (2222) is formed with a first coupling space (22221) so that a signal for determining whether there is contact with the inlet terminal (23) and a terminal for grounding can be accommodated on the inside.

[0057] Additionally, the second coupling extension part (2223) is formed with a second coupling space (22231) so that a relay part (2112) providing different electrodes for internal charging can be accommodated.

[0058] At this time, a pair of relay members (2112) forming different electrodes are prevented from coming into contact with each other within the second coupling space (22231). Additionally, a pair of relay bodies (2224) are formed that are coupled complementarily to the charging inlet bracket (21) to guide the coupling of the outlet terminal (211) and the inlet terminal (23).

[0059] Specifically, the relay body (2224) has a relay space (22241) that is open in the extension direction so that the relay unit (2112) is inserted and positioned in the rear of the extension direction, and the inlet terminal (23) is inserted in the front of the extension direction.

[0060] In addition, a second mounting portion (2225) is formed in communication with the relay space (22241) so that the second pad (232) is installed, and the first pad (231) is positioned in correspondence with the electrical connection relay portion of the outlet terminal (211), that is, the relay portion (2112) and the inlet terminal (23) come into contact.

[0061] To this end, the second mounting portion (2225) of one embodiment is formed with a mounting space (22251) formed parallel to the outer surface of the relay space (22241) and a support portion (22253) that protrudes from the mounting space (22251) and supports one side of the first pad (231) to prevent it from detaching from the mounting space (22251).

[0062] At this time, it is preferable to further form a second detection hole (22252) that penetrates the seating space (22251) and communicates with the relay space (22241) so that the first pad (231) can detect the rise of air caused by overheating of the terminal more quickly.

[0063] In addition, it is preferable that the second mounting portion (2225) of one embodiment be formed at the rear of the extension direction of the relay body (2224) so ​​that fire extinguishing gas is generated at the innermost part of the closed space formed when the charging outlet (10) is connected to the charging portion (20) of the electric vehicle.

[0064] Specifically, the second connecting extension part (2223) and the relay body (2224) have a structure that is complementarily connected to a charging inlet bracket in which an inlet terminal (23) is received, so that a closed space is formed in which the complementary connecting structure is stacked outwardly while the charging outlet (10) and the charging part (20) of the electric vehicle are connected.

[0065] At this time, the second mounting portion (2225) is formed at one end of a virtual air discharge path formed by a complementary coupling structure that forms a closed space. Accordingly, when the outlet terminal (211) overheats, it generates fire extinguishing gas to reduce the density of air inside the closed space and simultaneously discharges air to the outside sequentially, thereby increasing the fire extinguishing effect.

[0066] In addition, the second mounting portion (2225) of another embodiment may be formed in a recessed shape on the inner surface of the relay space (22241) so that the second pad (232) is attached to face the outer side of the relay portion (2112). In this case, the second pad (232) and the relay portion (2112) are formed to face each other directly, so a structure such as the second detection hole (22252) is not required.

[0067] Accordingly, the second mounting portion (2225) of the invention can be formed at any location where the second pad (232) can provide fire extinguishing gas to the closed space formed by the relay space (22241) and the communication space (22) in response to the air temperature around the relay portion (2112), and depending on the location where the mounting space (22251) is formed, a configuration such as the second detection hole (22252) may be added.

[0068] The fire extinguishing pad (230) is installed in the charging housing (220) and generates fire extinguishing gas when the terminal part (210) overheats, thereby preventing damage to surrounding parts due to heat and preventing secondary accidents such as explosions.

[0069] To this end, the fire extinguishing pad (230) is formed with a first pad (231) installed on the assembly body (221) corresponding to the position of one end of the connecting part (2111), and a second pad (232) installed on the coupling body (222) corresponding to the position of the relay part (2112).

[0070] Accordingly, the charging connection part (200) of the present invention is formed by separating the outlet terminal (211) into a connection part (2111) and a relay part (2112), and correspondingly, the charging housing (220) is also formed to be separated based on the open hole (140) formed in the main housing (100), so that only a part of the outlet terminal (211) can be replaced if damaged.

[0071] Accordingly, the maintenance costs of the charging outlet (10) are reduced, and the maintenance workability of the worker is significantly improved.

[0072] In addition, a fire extinguishing pad (230) is provided at the connection part (2111) and the cable (212) crimping part, where there is a high possibility of overheating during charging, and at the part where the relay part (2112) and the inlet terminal (23) come into contact, thereby minimizing damage caused by heat and preventing secondary accidents, thereby ensuring the safety of the user.

[0073] At this time, the fire extinguishing pad (230) is positioned so as not to come into direct contact with the terminal, thereby preventing the generation of fire extinguishing gas due to instantaneous overheating of the outlet terminal or heat generation within the allowable range, and increasing the lifespan of the fire extinguishing pad (230) itself.

[0074] Although preferred embodiments of the present invention have been described illustratively above, the scope of the present invention is not limited to such specific embodiments, and any modifications that are appropriately possible within the scope described in the claims fall within the scope of protection of the present invention.
