Abstract
Description
enclosure
[0001] The present invention relates to an enclosure, and more particularly, to an enclosure that accommodates a fuse box having a plurality of electrical components installed therein.
[0002] A fuse box is installed inside a vehicle to ensure stable power distribution and supply to numerous components performing various functions. To this end, numerous electrical components are installed inside and outside the fuse box to supply and cut off power.
[0003] At this time, since many electrical components are installed on the outside of the fuse box, an enclosure that includes an external housing that accommodates the fuse box is generally used to protect them and ensure that the fuse box can be stably installed in an optimal location inside the vehicle.
[0004] Additionally, a blocker is installed in the outer housing to provide a locking structure while the fuse box is seated in the housing so that it is stably fixed inside, and the blocker slides from an unfastened position to a fully fastened position to provide a fixing force.
[0005] Therefore, the worker had to check whether the blocker was completely fastened, which increased worker fatigue and caused a problem of reduced vibration resistance due to incomplete fastening.
[0006] Additionally, a problem arose in which the waterproofness of the grommet formed to connect the wires connected to the fuse box to external components and the connection part of the external housing was reduced, ultimately resulting in a decrease in electrical connection stability.
[0007] One embodiment of the present invention has been devised to solve the above problems, and aims to provide an enclosure that optimizes the assembly process and provides improved waterproofing and dustproofing properties.
[0008] An enclosure according to one embodiment of the present invention comprises: a housing formed by a body and a cover that are coupled to each other to form a closed receiving space; a fuse box installed in the receiving space; and a relay holder that is simultaneously coupled to the fuse box and the housing to fix the fuse box; wherein the relay holder is formed by a first fastening portion that is coupled to the fuse box in a first direction, and a second fastening portion that is coupled to the housing in a second direction, thereby fixing the fuse box to the receiving space in the second direction.
[0009] The fuse box may be formed with an installation surface arranged in a second direction while the electrical components are installed in a first direction, and an assembly surface arranged in the first direction along the periphery of the installation surface and having a coupling portion formed in the first direction, and the housing may have a second coupling portion formed that extends in a second direction from an inner surface of one of the body and the cover, and the relay holder may have a first fastening portion formed that extends inward in the first direction and is coupled to the first fastening portion, and a second fastening portion formed that extends outward in the second direction and is coupled to the second fastening portion, and may be coupled to the housing in the second direction while being coupled to the fuse box in the first direction.
[0010] The above relay holder is formed of a first relay part arranged in a first direction and having the first fastening part formed on the inside, and a second relay part extending in a third direction from the first relay part and having the second fastening part formed on the outside, so that the fuse box and the housing can be fastened at different positions and in different directions.
[0011] The first coupling portion and the first fastening portion may be formed as a first guide fixing portion that is complementarily coupled to each other to guide the first direction coupling while providing a fixing force in a third direction, and a first elastic fixing portion that is elastically deformed in the third direction while providing a fixing force in the first direction, and the second coupling portion and the second fastening portion may be formed as a second elastic fixing portion that is complementarily coupled to each other to provide a fixing force in a second direction while being elastically deformed in the first direction, and a second guide portion that accommodates both sides of the second elastic fixing portion.
[0012] The above relay holder may be formed in a plurality of pieces that are connected to the fuse box and the housing on both sides in the third direction.
[0013] It may further include a grommet installed through one side of the body; and a prevention seal disposed between the body and the cover and the grommet and the cover to prevent moisture from entering the receiving space.
[0014] The above-mentioned prevention seal may be formed by a seal body accommodated in an installation groove formed along the periphery of the cover, and a seal protrusion protruding from the seal body in a second direction to be in close contact with the body and the grommet while increasing the moisture inflow path.
[0015] The above-mentioned seal may further have a sealing portion formed by additionally protruding from the seal projection at the position of the boundary between the body and the grommet.
[0016] As discussed above, the problem-solving means of the present invention can be expected to produce various effects, including the following. However, the present invention is not established unless it exhibits all of the following effects.
[0017] The enclosure of the present invention is provided with a relay holder that is connected to the housing while installed in the fuse box and provides fixing force, so that the worker does not need to separately check whether the fuse box is fixed, thereby significantly reducing fatigue.
[0018] In addition, the relay holder is connected to the fuse box in a first direction and to the housing in a second direction, so that the repulsive force generated when connected to the housing does not affect the fixing force of the fuse box and the relay holder, thereby further optimizing the assembly process.
[0019] In addition, the fuse box, in which the electrical components are installed in the first direction by the relay holder, is installed in the second direction in the housing, thereby improving the utilization of the vehicle's internal space and design freedom.
[0020] In addition, the waterproof seal extends to the area where the cover and grommet meet, and a sealing projection is formed at the boundary area to improve the waterproofness of the space where the fuse box is accommodated, thereby ensuring electrical stability.

[0037] Referring to FIGS. 1 to 9, the enclosure (10) includes a housing (100) formed by a body (110) and a cover (120) that are coupled to each other to form a closed receiving space (130), a fuse box (200) installed in the receiving space (130), and a relay holder (300) that is simultaneously coupled to the fuse box (200) and the housing (100) to fix the fuse box (200), and the relay holder (300) is characterized in that it is formed by a first fastening portion (311) that is coupled to the fuse box (200) in a first direction, and a second fastening portion (321) that is coupled to the housing (100) in a second direction, thereby fixing the fuse box (200) to the receiving space (130) in the second direction.
[0038] At this time, a grommet (400) installed through one side of the body (110) and a prevention seal (500) disposed between the body (110) and the cover (120) and the grommet (400) and the cover (120) to prevent moisture from entering the receiving space (130) may be further included.
[0039] The enclosure (10) includes a housing (100) that accommodates a fuse box (200) inside, and protects an electrical component (230) installed outside the fuse box (200) from the outside, while allowing the fuse box (200) to be easily installed in an optimized location inside the vehicle.
[0040] The housing (100) is formed by a body (110) and a cover (120) that are connected to each other, and a receiving space (130) that is closed from the outside is formed on the inside by the connection of the body (110) and the cover (120), and a second connecting portion (140) to which a relay holder (300) is connected is formed on one of the body (110) and the cover (120).
[0041] Specifically, the body (110) and the cover (120) are coupled in a second direction, and a first internal space (111) constituting the lower side of the second direction of the receiving space (130) is formed in the body (110), a mounting portion (112) on which a grommet (400) is mounted is formed on one side, and a first locking portion (113) coupled with the cover (120) is formed on the outside.
[0042] At this time, the mounting portion (112) is opened upward in the second direction so as to be assembled in the second direction of the grommet (400), a mounting space (1121) in which the mounting body (411) is accommodated is formed, and a hook rib (1122) is formed along the inner circumference of the mounting space (1121).
[0043] The hooking rib (1122) is seated in the receiving groove (4111) formed in the grommet (400) seating body (411) and provides a hooking fixing force in the third direction when the grommet (400) is seated in the seating portion (112).
[0044] In addition, the first locking part (113) is formed on the outside of the body (110) to receive the second locking part (124) formed on the outside of the cover (120) inwardly, and is formed so that the second locking part (124) is caught and fixed in the second direction.
[0045] The cover (120) is formed with a second internal space (121) forming the upper side of the second direction of the receiving space (130) on the inside, and a mounting cover (122) is formed to cover the entire upper side of the mounting body (411) on one side, and an installation groove (123) is formed along the surface in contact with the body (110) to install a prevention seal (500).
[0046] At this time, the installation groove (123) is connected along the perimeter of the cover (120) and the mounting cover (122) to form an integral body, and accordingly, the anti-seal (500) comes into contact with all components formed between the receiving space (130) and the outside, that is, the body (110), the cover (120), and the grommet (400), thereby improving the waterproofness of the receiving space (130).
[0047] In addition, as the body (110) and the cover (120) are combined on the outside, a second locking part (124) is formed that is received in the first locking part (113) and elastically deforms while being fixed in the second direction to the first locking part (113) by a restoring force.
[0048] At this time, the first and second locking parts (113, 124) are described as an example embodiment, and may have various structures that provide fixing force in the second direction, and the structures described above may be formed by changing or crossing the body (110) and cover (120).
[0049] Preferably, the first and second locking parts (113, 124) are formed in multiple numbers along the perimeter of the housing (100) to provide a stable second-direction fixing force along the perimeter.
[0050] The second connecting portion (140) is formed by either the body (110) or the cover (120), and the relay holder (300) installed in the fuse box (200) is connected in the second direction to stably fix the fuse box (200) to the receiving space (130).
[0051] However, for the convenience of explanation, the following description will be based on an example in which the second connecting portion (140) is formed on the inner surface of the body (110).
[0052] In addition, the second elastic deformation receiving portion (141) and the second elastic deformation rib (142) forming the second connecting portion (140) are configured to be complementarily connected to the second catch (3211) and the guide rib (322) forming the second fastening portion (321), so that the second elastic deformation rib (142) forms a second elastic fixing portion together with the second catch (3211), and the second elastic deformation receiving portion (141) forms a second guide portion together with the guide rib (322).
[0053] Therefore, the structure of the second connecting portion (140) will be described in detail here, and the method of connecting will be described later together with the second connecting portion (321).
[0054] The second elastic deformation receiving portion (141) protrudes from the inner surface of the body (110) into the first internal space (111) and arranges the second elastic deformation rib (142) and the second fastening portion (321) inward to provide a deformation space for the second elastic deformation rib (142), while being formed parallel to the guide rib (322) to guide the second direction coupling of the relay holder (300).
[0055] In addition, the second elastic deformation rib (142) extends in the second direction from the inside of the second elastic deformation receiving portion (141) and is elastically deformed in the first direction as the relay holder (300) is coupled, and is caught and fixed to the second catch (3211) by the restoring force, thereby providing a second direction fixing force.
[0056] To this end, a second support protrusion (1421) is formed on one side of the second elastic deformation rib (142) to protrude and come into contact with the second catch (3211) and guide deformation in the first direction while being caught and fixed to the upper side of the second catch (3211) in the second direction.
[0057] Accordingly, the enclosure (10) of the present invention comprises a second connecting portion (140) to which a relay holder (300) connected to a fuse box (200) is additionally connected inside the housing (100), thereby providing a fixing force that stably fixes the fuse box (200) simultaneously with the assembly of the fuse box (200).
[0058] Accordingly, the assembly process is optimized by eliminating the need for a separate worker to confirm complete fastening. In addition, by securing fixing strength through elastic restoring force, the fuse box (200) can be relatively easily removed from the housing (100) as needed, thereby improving ease of maintenance.
[0059] The fuse box (200) is formed by a box body (210) in which a plurality of electrical components (230) are installed, and a first connecting portion (220) formed on the outside of the box body (210) and to which a relay holder (300) is connected. At this time, the box body (210) is formed by an installation surface (211) in which the electrical components (230) are installed in a first direction from the outside, an assembly surface (212) formed along the periphery of the installation surface (211), and a support surface (213) formed opposite the installation surface (211).
[0060] Specifically, the installation surface (211) and the support surface (213) are arranged parallel to the second direction while fixed to the housing (100), and the assembly surface (212) is arranged parallel to the first direction along the outer surface between the installation surface (211) and the support surface (213).
[0061] Accordingly, the box body (210) accommodates a plurality of electrical components (230) in the space between the installation surface (211) and the support surface (213), and a plurality of electrical components (230) are also installed on the outside of the installation surface (211). At this time, the electrical components (230) are installed in the first direction on the installation surface (211).
[0062] The assembly surface (212) is arranged parallel to the first direction, and a first connecting portion (220) is formed on the outside in the first direction so that the relay holder (300) is inserted and connected in the first direction.
[0063] In addition, the first-first guide fixing projection (221), the first-second guide fixing groove (222), the first-first elastic deformation rib (232) and the first-second catch projection (224) forming the first connecting portion (220) are configured to be complementarily connected to the first-first guide fixing groove (3111), the first-second guide fixing projection (3112), the first-first catch projection (3113) and the first-second elastic deformation rib (3114) forming the first connecting portion (311).
[0064] Accordingly, the first-first guide fixing projection (221) and the first-first guide fixing groove (3111) form a first guide fixing part together with the first-second guide fixing groove (222) and the first-second guide fixing projection (3112), and the first-first elastic deformation rib (232) and the first-second catch projection (224) form a first elastic fixing part together with the first-first catch projection (3113) and the first-second elastic deformation rib (3114).
[0065] Therefore, the structure of the first connecting portion (220) will be described in detail here, and the method of connecting will be described later together with the first connecting portion (311).
[0066] The first-first guide fixing projection (221) extends in the first direction and is inserted into the first-first guide fixing groove (3111) formed in the first fastening portion (311) to guide the coupling direction of the relay holder (300), and is formed with a cross-sectional area that extends from the inside to the outside to provide fixing force in the third direction when seated in the first-first guide fixing groove (3111).
[0067] In addition, the 1-1 guide fixing groove (3111) extends in the first direction, and the 1-1 guide fixing projection (221) formed in the first fastening portion (311) is seated therein to guide the coupling direction of the relay holder (300), and is formed with a cross-sectional area that extends from the outside to the inside to provide fixing force in the third direction when the 1-1 guide fixing projection (221) is accommodated.
[0068] In summary, the 1-1 guide fixing projection (221) and the 1-2 guide fixing projection (3112) have the same shape but differ only in their formation positions, and the 1-1 guide fixing groove (3111) and the 1-2 guide fixing groove (222) also have the same shape but differ only in their formation positions.
[0069] The 1-1 elastic deformation rib (232) extends in the first direction and elastically deforms in the third direction as the relay holder (300) is coupled, and at the same time, the 1-1 hooking projection (3113) is hooked and fixed by the restoring force, thereby providing a first direction fixing force.
[0070] To this end, a first-first support protrusion (2231) is formed on the first-first elastic deformation rib (232) to protrude from one side and contact the first-first hooking projection (3113) to guide elastic deformation while being hooked and fixed, thereby providing a first-direction fixing force.
[0071] In addition, the 1-2 hooking projection (224) protrudes in the third direction and comes into contact with the 1-2 elastic deformation rib (3114) as the relay holder (300) is coupled, guiding the third direction deformation and at the same time being hooked and fixed with the 1-2 support projection formed in the 1-2 elastic deformation rib (3114) to provide the first direction fixing force.
[0072] Therefore, the enclosure (10) of the present invention directly forms a first connecting portion (220) to which the relay holder (300) is connected in the first direction on the outside of the fuse box (200), so that the housing (100) can be assembled in a state in which the relay holder (300) is primarily connected when connected, thereby improving the worker's assembly workability.
[0073] In addition, when the first fastening portion (311) is formed in response to the first connecting portion (220) formed for connection between conventional fuse boxes or connection to a conventional external housing, the direction in which the fuse box (200) is assembled to the housing (100) can be changed through the relay holder (300) without a separate design change.
[0074] Accordingly, the invention can be used as is in various fuse boxes (200) through the relay holder (300), so the usability of the invention is very high, and the product development cost of the enclosure (10) to which the fuse box (200) is coupled in the second direction can also be reduced.
[0075] The relay holder (300) is formed by a first relay part (310) that is connected to the fuse box (200) in a first direction, and a second relay part (320) that is connected to the body (110) in a second direction, so that the fuse box (200) is installed in the housing (100) in a state where the installation surface (211) on which the electric component (230) is installed is arranged parallel to the second direction.
[0076] At this time, the first relay part (310) is arranged in the first direction, and the second relay part (320) is preferably arranged to extend from the first relay part (310) in the third direction and to the outside of the support surface (213) to limit movement in the first direction when the first fastening part (311) and the first coupling part (220) are coupled.
[0077] In addition, when the second direction connection of the second fastening portion (321) and the second connecting portion (140) is performed, the second direction load is prevented from being directly applied to the interface where the first fastening portion (311) and the first connecting portion (220) are connected, thereby ensuring the durability of the fuse box (200) and the relay holder (300).
[0078] Specifically, the first fastening portion (311) is formed with a first-first guide fixing groove (3111) extending in the first direction on the inner surface of the first relay portion (310) and a first-second guide fixing projection (3112), so that when the fuse box (200) and the relay holder (300) are combined, the first-first guide fixing projection (221) is inserted into the first-first guide fixing groove (3111) and is fixed, and the first-second guide fixing projection (3112) is inserted into the first-second guide fixing groove (222) and is fixed.
[0079] Accordingly, the fuse box (200) and the relay holder (300) provide fixing force in the third direction by the gradually expanding shape of the first-second guide fixing protrusion (3112) and the first-first guide fixing protrusion (221) at the same time as the guide is inserted in the first direction.
[0080] In addition, a first-first hooking projection (3113) protruding in a third direction and a first-second elastic deformation rib (3114) elastically deformed in a third direction are formed, so that when the fuse box (200) and the relay holder (300) are combined, the first-first hooking projection (3113) comes into contact with the first-first elastic deformation rib (232) and guides elastic deformation in the third direction, and the first-second elastic deformation rib (3114) is elastically deformed in the third direction by the first-second hooking projection (224).
[0081] At this time, the first-second support protrusion (31141) and the first-second hooking protrusion (224) are hooked and fixed in the first direction by the restoring force according to the elastic deformation of the first-second elastic deformation rib (3114) and the first-first elastic deformation rib (232), and the first-first hooking protrusion (3113) and the first-first support protrusion (2231) are hooked and fixed in the first direction.
[0082] In summary, the first fastening portion (311) and the first coupling portion (220) form a first guide fixing portion and a first elastic fixing portion that are connected to each other to provide fixing force in the first direction and the third direction, thereby being more firmly fixed to the fuse box (200).
[0083] The second fastening portion (321) has a second catch (3211) formed on the outer surface of the second relay portion (320) protruding in the first direction, so that the second elastic deformation rib (142) is elastically deformed in the first direction as the housing (100) and the relay holder (300) are combined.
[0084] In addition, a guide rib (322) extending in the second direction is further formed and arranged on both sides of the second elastic deformation rib (142) to guide the first and third direction combinations. At this time, the second catch (3211) is formed to be connected on both sides to the guide rib (322) arranged oppositely to more stably fix the second support protrusion (1421).
[0085] More specifically, the guide rib (322) is formed between the second direction rib forming the second elastic deformation receiving portion (141) and the second elastic deformation rib (142) on both sides where the second direction is arranged, thereby doubly preventing the third direction movement of the relay holder (300) while the second fastening portion (321) and the second joining portion (140) are fastened.
[0086] Therefore, the enclosure (10) of the present invention has a relay holder (300) that is simultaneously connected to the fuse box (200) and the housing (100), so that the fuse box (200) has fixing force in all of the first, second, and third directions within the receiving space (130), thereby improving the dustproofness of the product.
[0087] At this time, the direction in which the fuse box (200) and the housing (100) are combined is formed differently, so that the second direction fixing is possible within the housing (100) without changing the design of the fuse box (200).
[0088] In addition, the bonding force of the relay holder (300) and the fuse box (200) minimizes the influence of the repulsive force according to the bonding force of the housing (100) and the relay holder (300), thereby reducing worker fatigue and ensuring durability.
[0089] The grommet (400) is formed by a grommet body (410) formed by a mounting body (411) that is mounted on a mounting portion (112), a close-fitting body (412) that is placed in an open portion of the mounting portion (112), an extension grommet (420) that extends from the grommet body (410) so that wiring or the like can be connected to external components, and a communication space (430) formed inside the grommet body (410) and the extension grommet (420).
[0090] At this time, it is preferable that a receiving groove (4111) is further formed on the outside of the settling body (411) to receive a catch rib (1122) formed on the settling portion (112) so as to provide fixing force in the first or third direction when the grommet (400) is settling on the settling portion (112).
[0091] In addition, it is preferable that the sealing body (412) placed in the opening and in contact with the seal (500) be formed in a flat surface and be in uniform contact with the second protrusion (522) extended from the second body (512) over the entire area to effectively prevent moisture from entering the contact area between the cover (120) and the grommet (400).
[0092] The prevention seal (500) is formed by a seal body (510) formed along the perimeter of the cover (120) and a seal protrusion (520) protruding from the seal body (510) in a second direction and in close contact with the body (110) and the grommet (400), thereby preventing moisture from entering the receiving space (130).
[0093] Specifically, the seal body (510) is formed by a first body (511) formed at a portion where the cover (120) and the body (110) come into contact, and a second body (512) formed at a portion where the cover (120) and the grommet (400) come into contact. At this time, both sides of the second body (512) are connected to the first body (511) and formed as one piece.
[0094] However, the second body (512) is formed to have a larger area than the first body (511), thereby more effectively preventing moisture from flowing in along the surface where the cover (120) and the sealing body (412) come into contact.
[0095] To this end, the seal protrusion (520) is formed by a first protrusion (521) that protrudes from both sides of the first body (511) in the second direction, and a second protrusion (522) that protrudes from the second body (512) in the second direction, but in which the shape of the protrusion is formed continuously.
[0096] In addition, it is preferable that the seal body (510) further has a contact protrusion (530) formed from the second protrusion (522) at the boundary where the body (110) and the grommet (400) come into contact.
[0097] Accordingly, when the cover (120) is combined with the grommet (400) secured to the body (110), the adhesion projection (530) is deformed and adhered to the gap portion due to the tolerance that may occur during the production process of the body (110) and the grommet (400) and the round portion that inevitably occurs during the production process.
[0098] Accordingly, the seal (500) of the enclosure (10) of the present invention is formed at the contact portion of all components connecting the receiving space (130) and the outside, and applies a second protrusion (522) and a sealing protrusion (530) structure that seals the gap that is inevitably generated or due to production tolerance at the boundary portion of the grommet (400) and the body (110) formed of a different material from the body (110).
[0099] Accordingly, the waterproofness of the accommodation space (130) in which the fuse box (200) involved in power supply and cutoff with multiple components is accommodated is improved, thereby improving the reliability of the product and further securing electrical connection stability, thereby providing improved vehicle safety.
[0100] In summary, the enclosure (10) of the present invention is provided with a relay holder (300) that is connected to a second connecting portion (140) formed in a receiving space (130) while installed in a fuse box (200), thereby securing full fastening force of the fuse box (200) and reducing worker fatigue.
[0101] At this time, the relay holder (300) is fastened to the fuse box (200) in the first direction, but is fastened to the housing (100) in the second direction, so that the assembly force of the fuse box (200) and the relay holder (300) is not affected at all by the assembly repulsive force generated when assembling the housing (100), thereby providing a more stable fixing force.
[0102] In addition, by providing fixing force through elasticity, the fuse box (200) can be more easily separated when necessary, facilitating maintenance, and by arranging the assembly surface (212), which is generally formed wide for installing electrical components (230), in the second direction, the utilization of space inside the vehicle is improved, thereby realizing optimization of the assembly process.
[0103] Although the preferred embodiments of the present invention have been described above as examples, the scope of the present invention is not limited to these specific embodiments, and any modifications that may be appropriately made within the scope described in the claims fall within the scope of protection of the present invention.
