Description

Charging Terminal

The present invention relates to a charging terminal, and more specifically, to a charging terminal installed inside an inlet of an electric vehicle to relay battery charging.

Recently, as environmental issues have become an issue, eco-friendly vehicles have been highlighted to save energy and prevent environmental pollution. Accordingly, hydrogen fuel cell vehicles, biodiesel vehicles, and electric vehicles are attracting attention as replacements for vehicles that receive power from existing internal combustion engines.

Among these, the most active technology development is taking place in electric vehicles, which are vehicles that use electricity as a driving force. Electric vehicles are classified into EVs, PHEVs, and HEVs depending on the method of utilizing electric energy and the proportion of electricity used as a driving force, and EVs and PHEVs are equipped with rapid chargers and slow chargers to receive power from an external source.

At this time, a female terminal and a male terminal are installed to electrically connect the rapid charger and the slow charger, and the sizes of the female terminal and the male terminal are set to international standards to ensure charging compatibility of electric vehicles, and an insulating cap is assembled at the front end of the male terminal for the safety of the user.

For this purpose, a groove is formed at the front end of the male terminal into which an insulating cap is assembled, but a problem occurs in which the insulating cap comes off as the fixing force decreases due to repeated detachment and reattachment from the female terminal and an increase in the temperature of the male terminal caused by poor charging.

One embodiment of the present invention has been devised to solve the above problems, and aims to provide a charging terminal having an insulating cap that guides the direction of elastic deformation of a hook portion and increases the amount of deformation, thereby having improved fixing strength.

In one embodiment of the present invention, a charging terminal installed inside an inlet of an electric vehicle includes: a terminal body that is electrically connected by contact with a supply terminal installed inside a charging outlet; and an insulating cap that is assembled to one end of the terminal body to block the electrical connection; wherein the insulating cap is characterized in that it is formed by an insulating head that is arranged outside one end of the terminal body to provide insulation, and a fixed body that extends from the insulating head and is inserted into the first direction inside the terminal body so as to be elastically deformed in a second direction to generate a first fixing force and at the same time moves in the first direction to generate an additional fixing force in the second direction.

The terminal body may have an accommodation groove formed on the inner side of one end that is in direct contact with the supply terminal, in which the fixed body is accommodated, and the fixed body may have a deformation portion that expands and deforms in the second direction when accommodated in the accommodation groove at the end to generate the first fixing force, and a hook portion formed by a reinforcing portion that moves inwardly of the deformation portion in the first direction when in contact with the first-direction facing surface of the accommodation groove to generate the additional fixing force in the deformation direction of the deformation portion.

The above hook portion may further have a guide space formed inwardly to guide the second direction deformation of the hook portion, and the reinforcing portion may move in the first direction and adhere closely to the guide space to generate the additional fixing force while preventing the restoration of the deformation portion.

The above reinforcing part may further have a pressing projection formed on a contact surface facing the opposing surface, and when in contact, the deformation of the deformation part in the second direction and the movement of the reinforcing part in the first direction are increased.

The above guide space can be formed by a cover space in which a reinforcing member is received, and a close space in which the reinforcing member is in close contact, and the reinforcing member is placed in the cover space with only one end connected to the deformation member, and the hook part is moved in the first direction while being received in the receiving groove to close contact with the close space and generate the additional fixing force.

The above guide space may be formed with an inner surface tapered so that the open area gradually decreases as it goes inward, and the reinforcing portion is formed with a reinforcing body connected to the deformation portion and tapered in the same direction as the guide space, and a reinforcing protrusion protruding in a second direction at the end of the reinforcing body, so that the hook portion can move in the first direction while being received in the receiving groove so that the reinforcing protrusion comes into close contact with the guide space and generates the additional fixing force.

The above reinforcing projection is fixed to a first position of the guide space which is opened larger than the second direction cross-sectional area, but can be broken and adhered to the guide space according to movement in the first direction.

The above-mentioned receiving groove may be formed by a narrow portion that extends from the end of the terminal body, and an extended portion that extends from the narrow portion and forms an extended end that protrudes at the boundary, and the above-mentioned fixed body may be formed by an extended portion that extends from the insulating head and is received in the narrow portion, and a hook portion that protrudes from the extended portion and is fixed by being hooked to the extended end and is in close contact with the extended portion by the second-directional expansion deformation.

The above extension portion may further form a buffer groove that is inserted in a second direction at the boundary with the hook portion to relieve the pressure applied to the extension end when the hook portion is deformed.

It is preferable that the above hook portion be formed to be tapered so that the cross-sectional area gradually increases from the distal portion to the extension portion.

As examined above, the problem-solving means of the present invention can be expected to have various effects, including the following. However, the present invention is not established only when it exhibits all of the following effects.

The charging terminal of the present invention provides improved fixing force by expanding and deforming in a second direction as the insulating cap is assembled to the terminal body, thereby preventing the insulating cap from detaching even when repeatedly attached and detached from the charging outlet and when the temperature of the charging terminal rises, thereby improving product durability and reliability.

In addition, a pressing projection is further formed on the fixed body to increase the second direction deformation of the insulating cap when assembling the terminal body and the insulating cap, and a guide space is formed on the inside to guide the second direction deformation, thereby increasing the effect of improving the fixing force.

A buffer groove is formed on one side of the extension portion to relieve the pressure generated by the second direction expansion, thereby maximizing the durability enhancement effect, and the hook portion is tapered so that the cross-sectional area gradually increases from the distal end to the extension portion, thereby reducing the insertion/extraction force generated when inserting into a narrow portion.

Referring to FIGS. 1 to 10, a charging terminal (10) installed inside an inlet of an electric vehicle according to an embodiment of the present invention includes a terminal body (100) that is electrically connected by making contact with a supply terminal installed inside a charging outlet, and an insulating cap (200) that is assembled to one end of the terminal body (100) to block the electrical connection, wherein the insulating cap (200) is formed by an insulating head (210) that is arranged on the outside of one end of the terminal body (100) to provide insulation, and a fixing body (220) that extends from the insulating head (210) and is inserted into the first direction inside the terminal body (100) so as to be elastically deformed in a second direction to generate a first fixing force and at the same time moves in the first direction to generate an additional fixing force in the second direction.

The charging terminal (10) is installed inside the inlet of the electric vehicle and is electrically connected to the supply terminal installed inside the charging outlet to electrically connect an external charging device and the battery of the electric vehicle to relay charging.

To this end, the terminal body (100) is formed integrally with a contact portion (110) electrically connected to the supply terminal inside the charging outlet and a connection portion (120) electrically connected to the charging wire connected to the battery, which extend in the first direction.

The contact portion (110) extends in the direction in which the charging outlet and the charging inlet are coupled, i.e., in the first direction, and is inserted into the inside of the supply terminal to make direct contact and electrical connection, and a receiving groove (111) into which an insulating cap (200) is assembled is formed on the inside of the front end.

Here, the receiving groove (111) is formed at the front end of the first direction of the contact portion (110) so that the front end of the terminal body (100) can be electrically blocked by the insulating cap (200), and this provides insulation to the end of the charging terminal (10) formed to be exposed to the inlet, thereby providing improved stability.

Specifically, the receiving home (111) is formed by a narrow portion (1111) extending from the front end of the terminal body (100) so that an insulating cap (200) can be assembled without a separate fixing member, an extended portion (1112) extending rearward in the first direction from the narrow portion (1111) and having an expanded open area, and an extended end (1113) formed to protrude at the boundary between the narrow portion (1111) and the extended portion (1112).

Accordingly, the hook portion (222) of the insulating cap (200) is inserted in the first direction while being pressed in the second direction in the narrow portion (1111), and is received while being restored in the expanded portion (1112) and is fixed by being caught in contact with the expanded end (1113).

In addition, the connecting portion (120) is formed toward the rear in the first direction, and a groove is formed on the inside to accommodate a charging wire connected to the battery so that the charging wire can be electrically connected, and the charging wire is compressed while accommodated in the groove.

Therefore, the charging terminal (10) of the present invention can be easily assembled to the terminal body (100) by a worker pressing the insulating cap (200), and can be electrically connected through pressing with the charging wire, thereby reducing worker fatigue and improving workability.

The insulating cap (200) is formed by an insulating head (210) that is positioned on the front outer side of the terminal body (100) to provide insulation, and a fixed body (220) that extends from one side of the insulating head (210) and is fixed by being hooked into a receiving groove (111), and is assembled to one side of the terminal body (100) to block the electrical connection of one end of the charging terminal (10).

At this time, it is preferable that the insulating head (210) be formed in a cone shape so that the cross-sectional area becomes narrower as it goes forward in the first direction, thereby reducing the rate of increase in insertion/withdrawal force that occurs when inserted into the inside of the supply terminal, and it is preferable that a void home (211) formed by removing a portion of the insulating head (210) to the outside is formed to increase the effect of reducing the insertion/withdrawal force.

However, the void home (211) is optionally formed in the insulating head (210) according to the design, and its size and number can also be changed in various ways.

The fixed body (220) is formed by an extension (221) accommodated in a narrow portion (1111) and a hook portion (222) accommodated in an extension portion (1112). One side of the hook portion (222) is hooked and fixed to an extension end (1113) to secure the insulating cap (200) to the terminal body (100).

To this end, the extension part (221) is formed as an extension body (2211) that extends in a first direction from the insulating head (210) and is received in a narrow part (1111) while the insulating cap (200) is coupled to the terminal body (100), and a buffer groove (2212) that is inserted in a second direction at the boundary with the hook part (222) and relieves a pressure force that may be generated on the extension body (2211) by the extension end (1113).

Here, the buffer groove (2212) removes the pressure applied to the extension body (2211) by the extension end (1113) protruding inwardly from the receiving groove (111) while the insulating cap (200) is fixedly caught in the receiving groove (111), thereby preventing fatigue from accumulating on the insulating cap (200), thereby providing an effect of improving the durability of the product.

Specifically, the hook portion (222) is formed by a deformation portion (2221) that provides a first-directional fixing force by being hooked and fixed to an expansion end (1113) while allowing the insulation cap (200) to be assembled into the receiving groove (111) through elastic deformation, a reinforcing portion (2222) that moves inwardly of the deformation portion (2221) in the first direction and generates additional fixing force, a guide space (2223) that guides the second-directional deformation of the deformation portion (2221), and a pressure projection (2224) that protrudes from one side of the deformation portion (2221) and increases the second-directional deformation of the deformation portion (2221), thereby improving the fixing force with the terminal body (100) while not damaging the assembling property of the insulation cap (200), thereby improving the durability and reliability of the product.

The deformation portion (2221) extends to the rear end of the extension body (2211) in the first direction, protrudes in the second direction, and is received in the extension end (1113) and is fixed by contacting the extension end (1113), thereby providing a fixing force in the forward direction in the first direction.

The reinforcing member (2222) is formed by a reinforcing body (22221) that extends inwardly while connected to the first-direction rear end of the hook member (222) and a reinforcing projection (22222) that protrudes forward in the first direction of the reinforcing body (22221), thereby interfering with the restoration of the deformed member (2221) in the second direction in which the cross-sectional area decreases when the insulating cap (200) is moved forward in the first direction a predetermined distance from the initial position in the state in which the terminal body (100) is assembled, thereby providing additional fixing force.

At this time, the shape of the reinforcing part (2222) can have various shapes that can be moved in the first direction and be closely attached to the guide space, and in one embodiment, the insulating cap (200) has a reinforcing body (22221) that has a shape whose cross-sectional area becomes narrower from the rear to the front in the first direction, thereby securing a certain area or more of the area of the part connected to the hook part (222) while preventing interference with the movement in the first direction within the guide space (2223), and the reinforcing protrusion (22222) has the same cross-sectional area and extends in the first direction to secure a close space with the guide space (2223), thereby stably preventing the deformation part (2221) from being deformed in the direction in which the cross-sectional area decreases.

In addition, the insulating cap (200) of another embodiment is the same as the insulating cap (200) of one embodiment in that the reinforcing body (22221) has a shape in which the cross-sectional area becomes narrower from the rear to the front in the first direction, thereby securing a certain area of the portion connected to the hook portion (222) while preventing interference with movement in the first direction within the guide space (2223).

However, initially, the reinforcing projection (22222) is connected to the inside of the guide space (2223), but is formed so that the connection portion is broken when the insulating cap (200) is completely fastened to the terminal body (100), so that if the worker does not completely fasten the insulating cap (200), the connection portion is not broken, preventing the insulating head (210) from being seated on the terminal body (100).

Accordingly, the worker can visually check whether the insulation cap (200) is completely fastened, thereby ensuring both workability and product durability.

In addition, in order to ensure ease of breakage, it is preferable that the insulating cap (200) of another embodiment has a shape in which the cross-sectional area becomes narrower as it goes forward in the first direction, like the reinforcing body (22221).

At this time, the additional fixing force of the reinforcing projection (22222) is generated when the guide space (2223) also has a shape that narrows forward in the first direction and the reinforcing projection (22222) is moved a predetermined distance and comes into contact with the guide space (2223).

As described above, depending on the shape of the reinforcing portion (2222) formed on the inside of the deformation portion (2221), the guide space (2223) that accommodates it can also be deformed and formed into various shapes.

The guide space (2223) of one embodiment refers to an empty space formed inwardly by penetrating the deformation portion (2221), and more specifically, it is formed by a cover space (22231) in which the reinforcement portion (22222) is received at the initial position, and a close space (222232) in which the reinforcement protrusion (22222) is closely contacted, thereby securing the deformation space of the deformation portion (2221) while allowing the reinforcement portion (22222) to move smoothly and be stably fixed.

At this time, the guide space (2223) is formed as a single space, but for convenience of explanation, it is divided into a cover space (22231) and a close space (22232), and is physically partitioned by a reinforcing protrusion (22222).

To explain this more specifically, the cover space (22231) is formed in the first direction by the reinforcing projection (22222) so as to facilitate second-direction deformation while the deformation portion (2221) penetrates the narrow portion (1111) and at the same time extends in the first direction so as to enable movement of the reinforcing body (22221) in the first direction, and the close contact space (22312) is preferably formed in a direction crossing the first direction so as to facilitate second-direction expansion deformation of the deformation portion (2221) by the pressing force generated by the contact between the opposing surfaces of the pressing projection (2224) and the receiving groove (111) and at the same time prevent restoration of the deformation portion (2221) in the second direction by the reinforcing projection (22222).

The cover space (22231) is formed parallel to the first direction to secure a second direction deformation space of the narrow section (1111) so that the cross-sectional area becomes smaller while the hook section (222) moves along the narrow section (1111), thereby facilitating a reduction in the cross-sectional area and reducing the elastic deformation rate, thereby also reducing fatigue during workability.

The close contact space (22232) is formed in a direction perpendicular to the first direction, so that when a pressing force is generated by the close contact between the pressing projection (2224) and the receiving groove (111) while the hook portion (222) is accommodated in the expansion portion (1112), the first direction deformation space of the hook portion (222) is secured so that the second direction elastic deformation occurs more efficiently by the pressing force, and the reinforcing projection (22222) is ensured to be in close contact with the inside, thereby preventing the second direction deformation of the hook portion (222) from being restored in situations such as a temperature rise.

In summary, the close contact space (22232) secures a first direction space of the hook portion (222) to reduce the first direction strain of the hook portion (222) by the pressing force, induces second direction elastic deformation of the narrow portion (1111) so that the cross-sectional area increases, thereby increasing the contact area between the hook portion (222) and the receiving groove (111) and providing additional fixing force in the second direction.

In another embodiment, the guide space (22223) has a shape in which the open area gradually decreases as it goes forward in the first direction, and initially, the reinforcing part (2222) is arranged at a position where the open area of the reinforcing projection (22222) and the cover space (22231) are the same so that no additional fixing force in the second direction is generated, but when the reinforcing part (22222) is moved a predetermined distance in the first direction by the pressure projection (2224), the open area of the guide space (22223) decreases so that the reinforcing projection (22222) is brought into close contact.

The pressurizing projection (2224) is formed by protruding from the rear of the hook portion (222) in the first direction, and when the hook portion (222) is completely accommodated in the extension portion (1112), i.e., when the insulating cap (200) and the terminal body (100) are completely connected, it is pressed against a surface forming the accommodation groove (111) that faces the hook portion (222) in the first direction, thereby increasing the elastic deformation of the hook portion (222) in the second direction.

At this time, the pressurizing projection (2224) is formed integrally with the insulating cap (200) and is formed of an elastically deformable material so that when in close contact with the opposing surface, a pressurizing force is generated in the first direction forward, while at the same time, it does not prevent the entire rear surface area of the first direction of the hook portion (222) from contacting the opposing surface.

In addition, the pressurizing projection (2224) is formed to protrude at the end of the reinforcing portion (2222) so that when the insulating cap (220) is assembled to the terminal body (100), the reinforcing portion (2222) naturally moves forward in the first direction to secure additional fixing force.

Therefore, the insulating cap (200) of the charging terminal (10) of the present invention is formed with a guide space (2223) to facilitate assembly with the terminal body (100), and at the same time, a pressing projection (2224) is formed to provide additional fixing force in addition to the fixing force generated by direct contact with the extension end (1113).

Accordingly, even when an overheating phenomenon such as an overload of the charging terminal (10) occurs, the insulating cap (200) is prevented from being arbitrarily detached from the terminal body (100), and at the same time, a certain level of durability is maintained even when repeatedly attached and detached from the charging outlet, thereby significantly improving the reliability of the product and the safety of the user.

In addition, the reinforcing portion (2222) and the guide space (2223) of the insulating cap (200) may have various corresponding shapes that do not generate a second direction fixing force in the initial position according to the design, but generate additional fixing force by movement in the first direction.

To explain more specifically the process of assembling the insulating cap (200) of the present invention to the terminal body (100), the hook portion (222) is inserted into the receiving groove (111) formed in the first direction forward of the terminal body (100), and at this time, the cross-sectional area of the hook portion (222) is formed to be larger than the open area of the narrow portion (1111), so that it is inserted while elastically deforming in the second direction, and an insertion force is generated according to contact with the narrow portion (1111).

Therefore, in order to improve the workability of the worker, the hook part (222) is formed to be inclined so that the cross-sectional area gradually increases to reduce the contact area, and a cover space (22231) is formed inside the hook part (222) to secure a deformation space of the hook part (222) so that the hook part (222) can be deformed more easily.

When the hook part (222) penetrates the narrow part (1111) and is positioned at the expanded part (1112), the hook part (222) is restored in the second direction by the restoring force generated by the elastic deformation, and a first direction forward hooking fixing force is generated at the expanded part (1113), and at the same time, when the pressure projection (2224) comes into contact with the opposite surface formed in the first direction of the receiving groove (111), the reinforcing part (2222) moves in the first direction and comes into contact with the close space (22232), thereby generating additional fixing force.

Here, the pressurizing projection (2224) is brought into contact with the opposing surface before the insulating gap is completely assembled into the receiving groove (111), and when the insulating cap (200) is completely assembled into the receiving groove (111), it is elastically deformed in the first direction so that the surface formed toward the rear of the first direction of the hook portion (222) is in close contact with the opposing surface.

Accordingly, the pressurizing projection (2224) generates a pressing force in the first direction forward, and induces a second direction additional deformation of the hook portion (222) through the close space (22232) that offsets the first direction deformation inwardly, thereby increasing the contact area between the insulating cap (200) and the terminal body (100), and at the same time, by close contacting the reinforcing projection (22222) with the close space (22232), fundamentally prevents the second direction additional deformation from being restored, thereby securing a second direction additional fixing force.

Accordingly, the charging terminal (10) of the present invention is prevented from being arbitrarily detached from the terminal body (100) of the insulating cap (200) even due to temperature rise, repeated detachment, etc., thereby significantly improving the durability and stability of the product.

Although the preferred embodiments of the present invention have been exemplified above, the scope of the present invention is not limited to these specific embodiments, and appropriate modifications within the scope described in the claims fall within the scope of protection of the present invention.
