Description

Technical Field

[0001] The present invention relates to a fuse box cover unit and a terminal connection device for a vehicle including the same, and more specifically, to a fuse box cover unit in which an electrical connector can be easily mounted in a fuse box of a vehicle and a terminal connection device for a vehicle including the same.

[0002] This application claims priority based on Korean Patent Application No. 10-2022-0110381 filed on August 31, 2022, and all of the contents disclosed in the specification and drawings of the application are incorporated into this application.

Background Art

[0003] Recently, various electrical and electronic devices used in vehicles have emerged. Examples of such electrical and electronic devices include an event data recorder (accident information measurement / recording device), navigation, a parking lot number plate, monitoring equipment, diagnostic equipment, and the like. Basically, various electrical and electronic devices used in a vehicle are configured to operate by receiving power supply from a main battery mounted on the vehicle.

[0004] Such electrical and electronic devices are generally provided in a fuse box, which is a box-shaped space where a plurality of electrical components such as fuses and relays in a vehicle are aggregated in one place. In the fuse box, electrical terminals such as an OBD slot for connection to an electrical system such as an on-vehicle diagnostic device (OBD: On Board Diagnosis) are provided together.

[0005] The recent progress in the popularization of electric vehicles is remarkable. Along with this, the connection of vehicle OBD connectors that are connected to the OBD slots in such fuse boxes is frequently carried out. Conventionally, when vehicle diagnosis is required, the vehicle OBD connector connected to the OBD slot is connected to the OBD slot in the fuse box, and through this, detailed data of the vehicle battery is acquired, saved, and wirelessly transmitted to the server for utilization of these data.

[0006] However, for the connection between an electrical connector such as a conventional OBD connector and an electrical slot such as an OBD slot, the fuse box cover covering the fuse box must necessarily be removed from the fuse box. As a result, the wiring has to be exposed in the vehicle interior, and the removed fuse box cover has to be separately placed in the vehicle interior, etc. This causes trouble and annoyance to the user during installation and also causes visual inconvenience.

[0007] Therefore, when connecting an electrical connector such as an OBD connector, it is desired to explore a solution that can guide the easy installation of the electrical connector.

[0026] The terms and words used in this specification and the claims are not to be construed as being limited to their ordinary or dictionary meanings. Instead, in accordance with the principle that the inventor can appropriately define the concept of the terms in order to explain the invention in the best way, they are construed in meanings and concepts corresponding to the technical idea of the present invention.

[0027] Therefore, it should be understood that the embodiments described in this specification and the configurations shown in the drawings are merely preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention. Thus, there may be various equivalents and modifications that can replace them at the time of this application.

[0028] FIG. 1 is a diagram for explaining a terminal connection device for a vehicle according to an embodiment of the present invention, and FIG. 2 is a schematic cross-sectional view of the terminal connection device for a vehicle in FIG. 1.

[0029] Referring to FIGS. 1 and 2, a terminal connection device 1 for a vehicle provided in the vehicle may include a fuse box 10 mounted in the interior of the vehicle and a fuse box cover unit 50 for sealing the fuse box 10.

[0030] The vehicle may be an automobile and may be provided as an electric vehicle using a battery as an energy source. The battery may be a secondary battery and may be provided as a cylindrical secondary battery, a square secondary battery, or a pouch-type secondary battery.

[0031] The fuse box 10 may be a box-shaped space that aggregates a plurality of electrical components 17 such as fuses and relays in one place in the vehicle. An electrical slot 15 such as an OBD slot for connection to an electrical system such as OBD (On Board Diagnosis) may be provided together in the fuse box 10.

[0032] The fuse box cover unit 50 may be provided to be openable and closable with respect to the fuse box 10 according to a user operation, and an electrical connector 400 connectable to the electrical slot 15 provided in the fuse box 10 may be integrally formed.

[0033] In the present embodiment, with the electrical connector 400 being integrally provided in the fuse box cover unit 50, it is possible to guide an even easier connection of the electrical connector 400 to the electrical slot 15 side.

[0034] Here, the electrical connector 400 can be provided on the back side of the fuse box cover unit 50, which is the opposite side of the front face that is exposed in the vehicle interior when the fuse box cover unit 50 is mounted.

[0035] In this embodiment, since the electrical connector 400 provided in the fuse box cover unit 50 is provided on the back side of the fuse box cover unit 50, it is possible to prevent the exposure of the electrical connector 400 in the vehicle interior, prevent the exposure of unnecessary wiring, prevent the visual inconvenience to the user, and ensure good appearance.

[0036] Also, in this embodiment, when connecting the electrical connector 400 and the electrical slot 15, since the fuse box cover unit 50 is arranged while covering the fuse box 10, it becomes unnecessary to remove the fuse box cover unit 50 even after the connection.

[0037] As a result, in this embodiment, after the connection between the electrical connector 400 and the electrical slot 15, it becomes unnecessary to secure space by the removed fuse box cover unit 50, and inconveniences such as the deterioration of appearance caused by the removed fuse box cover unit 50 can be eliminated.

[0038] Hereinafter, such a fuse box cover unit 50 will be described more specifically.

[0039] FIG. 3 is a diagram for explaining the fuse box cover unit of the terminal connection device for a vehicle in FIG. 2, FIG. 4 is a schematic rear perspective view of the fuse box cover unit in FIG. 3, and FIG. 5 is a view of the fuse box cover unit in FIG. 4 with the PCB case removed.

[0040] Referring to FIGS. 3 to 5, and FIGS. 1 and 2 above, the fuse box cover unit 50 may include a cover body 100, an electrical PCB 200, a connection wire 300, and the electrical connector 400.

[0041] The cover body 100 forms the appearance of the fuse box cover unit 50 and can be detachably coupled to the fuse box 10. When coupled to the fuse box 10, the fuse box 10 can be sealed.

[0042] A receiving space capable of receiving the electrical PCB 200 described later may be provided on the back surface of the cover body 100. Such a receiving space may be formed to be larger than the thickness of the electrical PCB 200 so that the electrical PCB 200 does not protrude outside the cover body 100 when the electrical PCB 200 is mounted as described later.

[0043] Hereinafter, such a cover body 100 will be described in more detail.

[0044] FIG. 6 is a diagram for explaining the cover body of the fuse box cover unit of FIG. 4.

[0045] Referring to FIG. 6 and FIGS. 1 to 5 above, the cover body 100 may include a cover hook 103, a cover handle 105, and a PCB fixing portion 107.

[0046] The cover hook 103 is formed at the peripheral edge of the cover body 100 and may be provided as at least one or a plurality thereof. Hereinafter, in this embodiment, the description will be limited to the case where a plurality of the cover hooks 103 are formed.

[0047] The plurality of cover hooks 103 are hooked on the peripheral edge of the fuse box 10, and when the fuse box cover unit 50 is coupled to the fuse box 10, the cover body 100 can be guided so as to be more stably fixed to the fuse box 10.

[0048] The cover handle 105 is for guiding user operations, is formed on the cover body 100, and can be provided in the shape of a slot with a predetermined size. Specifically, the cover handle 105 can be formed at the lower end of the central portion of the cover body 100 and provided in the shape of an open slot large enough for a user's hand or the like to pass through.

[0049] The PCB fixing portion 107 is for fixing the electrical PCB 200 described later, is provided on the back surface of the cover body 100, and can be provided with at least one or a plurality thereof. Hereinafter, in this embodiment, the description will be limited to the case where a plurality of the PCB fixing portions 107 are provided.

[0050] The plurality of PCB fixing portions 107 can be provided in the shape of bosses having grooves with a predetermined depth inside. The electrical PCB 200 described later can be fitted into such a plurality of PCB fixing portions 107. Through the plurality of PCB fixing portions 107, the electrical PCB 200 described later can be fixed to the cover body 100 more stably.

[0051] The electrical PCB 200 can be provided on the back surface of the cover body 100. In this embodiment, such an electrical PCB 200 can be mounted on the cover body 100 and the electrical PCB 200 can be integrally provided in the fuse box cover unit 50.

[0052] Such an electrical PCB 200 is an OBD circuit board for vehicle diagnosis and management and can be provided as an OBD electrical system. Such an electrical PCB 200 can include an OBD data collection unit.

[0053] A wireless communication module capable of supporting wireless communication can be mounted on the electrical PCB 200. Such a wireless communication module can guide wireless connection with vehicle electronic devices, a user's smartphone, a tablet PC, or the like.

[0054] The connection wire 300 is connected to the electrical PCB 200 and can be provided with a predetermined length. Specifically, one end of the connection wire 300 is connected to the electrical PCB 200, and an electrical connector 400 described later can be provided at the other end of the connection wire 300.

[0055] The electrical connector 400 can be attached to the end of the connection wire 300 and connected to the electrical PCB 200 via the connection wire 300. Specifically, the electrical connector 400 can be attached to the other end of the connection wire 300. Such an electrical connector 400 can be provided as an OBD connector.

[0056] The fuse box cover unit 50 may include a PCB case 500.

[0057] FIG. 7 is a diagram for explaining the PCB case of the fuse box cover unit of FIG. 3, and FIG. 8 is a schematic rear perspective view of the PCB case of FIG. 7.

[0058] Referring to FIGS. 7, 8 and the previous FIGS. 1 to 6, the PCB case 500 can be provided so as to cover the electrical PCB 200. Such a PCB case 500 can cover the electrical PCB 200 together with the cover body 100 so as not to expose the electrical PCB 200 to the outside of the fuse box cover unit 50.

[0059] Such a PCB case 500 may be provided with a cover connection portion 502 and a wire groove 505.

[0060] The cover connection portion 502 is for more stably fixing the PCB case 500 when connecting the cover body 100 of the PCB case 500, and can be provided on the upper side of the PCB case 500.

[0061] Such a cover connection part 502 projects from the upper end part of the PCB case 500 by a predetermined length and can be provided in at least one or a plurality thereof. Hereinafter, in the present embodiment, the description will be limited to the case where the cover connection parts 502 are provided in a pair.

[0062] The pair of cover connection parts 502 project from the upper end part of the PCB case 500 and can be arranged at a predetermined distance from each other. Such a pair of cover connection parts 502 can be fitted into the upper end part of the cover main body 100 to more firmly fix the PCB case 500 to the back surface of the cover main body 100.

[0063] The wire groove 505 is for passing the connection wire 300, is formed on one side of the side surface of the PCB case 500, and can be provided in a shape of a predetermined curved groove so that the connection wire 300 can pass through.

[0064] On the other hand, the PCB case 500 may include an electromagnetic wave shielding material 550.

[0065] The electromagnetic wave shielding material 550 is for reducing the influence of noise from the electrical components of the vehicle and improving the directivity of the antenna during wireless communication, and can be provided as an electromagnetic wave shielding sheet 550 and adhered to the inner surface of the PCB case 500.

[0066] Thereby, in the present embodiment, when performing wireless communication via the electrical PCB 200 using the electromagnetic wave shielding material 550, the influence of noise from the vehicle side is suppressed as much as possible, and during wireless communication, the directivity of the antenna can be significantly improved so as to be directed only to the front side of the fuse box cover unit 50, which is the outside, that is, the inside of the vehicle compartment side, rather than the inside of the vehicle.

[0067] On the other hand, it goes without saying that it is also possible to manufacture the PCB case 500 itself from a material having an electromagnetic wave shielding function without separately adhering an electromagnetic wave shielding material 550 to such a PCB case 500.

[0068] Next, the connection and interference prevention mechanism of the OBD electrical system through the fuse box cover unit 50 will be described in more detail.

[0069] FIG. 9 is a diagram for explaining the interference prevention mechanism through the fuse box cover unit of FIG. 2.

[0070] Referring to FIG. 9, in the case of a conventional fuse box cover, it is disposed on the line indicated by the dashed line P when mounted on the fuse box 10. As a result, the conventional fuse box cover causes interference with the electrical connector 400 and cannot cover the fuse box 10 when mounting the electrical connector 400.

[0071] In the case of the fuse box cover unit 50 according to the present embodiment, the cover body 100 protrudes forward from the peripheral edge of the fuse box 10 by a predetermined depth, and a predetermined space S can be formed on the back surface of the cover body 100 when the fuse box cover unit 50 is mounted on the fuse box 10. Such a predetermined space S can form an interference prevention space capable of preventing interference with the electrical connector 400.

[0072] Thereby, the fuse box cover unit 50 according to the present embodiment can eliminate interference with the electrical connector 400 when connecting the electrical connector 400 and the electrical slot 15, and can cover the fuse box 10 with the fuse box cover unit 50 even when mounting the electrical connector 400.

[0073] Therefore, in this embodiment, after connecting the electrical connector 400 to the electrical slot 15 of the fuse box 10, the fuse box cover unit 50 can be covered, and the electrical connection of the OBD electrical system can be maintained even in a state where the fuse box cover unit 50 is coupled to the fuse box 10 without exposing wiring or the like to the outside.

[0074] Further, since the electrical PCB 200 and the electrical connector 400, which are OBD electrical systems, are integrally provided in the fuse box cover unit 50, an electronic device such as an OBD electrical system can be modularized in the fuse box cover unit 50.

[0075] In addition, since the electrical PCB 200 is disposed above the cover handle 105 on the back surface of the fuse box cover unit 50, interference by the electrical PCB 200 can be prevented when the cover handle 105 is operated by a user.

[0076] Hereinafter, the connection of the electrical connector 400 of the fuse box cover unit 50 will be described more specifically.

[0077] When connecting the electrical connector 400 and the electrical slot 15, a user or the like connects the electrical connector 400 provided on the back surface of the fuse box cover unit 50 to the electrical slot 15 in the fuse box 10. After that, a user or the like fixes the cover body 100 of the fuse box cover unit 50 to the fuse box 10 so as to seal the fuse box 10.

[0078] Thus, in this embodiment, it is possible to realize the connection of the OBD electrical system while the fuse box cover unit 50 covers the fuse box 10, eliminating the need to remove the fuse box cover unit 50 after OBD connection, preventing the exposure of the interior space of the vehicle such as wiring, and resolving visual inconvenience.

[0079] Also, during the connection, the fuse box cover unit 50 can be arranged while covering the fuse box 10, fundamentally preventing the generation of dead space in the interior space of the vehicle due to the removed fuse box cover unit 50.

[0080] On the other hand, the user or the like can insert a hand into the cover handle 105 of the cover body 100 to more easily perform operations such as fixing the cover body 100 to the fuse box 10 and removing it from the fuse box 10.

[0081] At this time, since the electrical PCB 200 is arranged above the cover handle 105 on the back surface of the cover body 100, it is possible to prevent problems of interference with the electrical PCB 200 when the user operates the cover handle 105.

[0082] In addition, as the cover handle 105 is provided in the shape of an opened slot, a predetermined interference prevention space S can also be formed behind the cover handle 105 together with the opened space, effectively ensuring a space for smooth user operation.

[0083] As described above, the present invention has been described with reference to limited embodiments and drawings. However, the present invention is not limited thereto, and it goes without saying that various modifications and variations are possible within the equivalent scope of the technical idea and claims of the present invention by those having ordinary knowledge in the technical field to which the present invention pertains.

[0084] On the one hand, in this specification, directional terms such as up, down, left, right, front, and back are used, but these terms are merely used for ease of explanation, and it is obvious to those skilled in the art of the present invention that they may vary depending on the position of the object of interest, the position of the observer, etc.
