[0031] FIG. 1 is an exploded perspective view illustrating a connector assembly according to one embodiment, FIG. 2 is a cross-sectional view illustrating a housing according to one embodiment, and FIG. 3 is a cross-sectional view illustrating a housing and a protective part according to one embodiment.

[0032] Referring to FIGS. 1 to 3, the connector assembly may include a first connector and a second connector that can be joined or separated from each other. It may include a first connector (1) and a second connector (2). Either one of the first connector (1) and the second connector (2) may be inserted toward the other connector by an external force. Either one of the first connector (1) and the second connector (2) may be referred to as a female connector, and the other connector may be referred to as a male connector.

[0033] The first connector (1) may include a housing (11) and a protective part (12). The protective part (12) may be provided on the inside of the housing (11), as shown in FIG. 3. FIG. 1 illustrates the protective part (12) separated from the inside of the housing (11) for convenience of explanation. Although not illustrated, a stopper may be provided on the upper part of the housing (11) to prevent the protective part (12) from unintentionally detaching. For example, the stopper may be formed to protrude inward from the inner surface of the housing (11) and may be caught on the upper part of the protective part (12).

[0034] The central portions of the housing (11) and the protection part (12) may be spaced apart from each other in the z-axis direction. Through such a structure, the protection part (12) can improve the alignment of a plurality of terminals (not shown) mounted on the first connector (1). A first portion of each of the plurality of terminals (not shown) is supported by the housing (11), and a second portion spaced apart from the first portion in the z-axis direction may be supported by the protection part (12).

[0035] At the edge portions of each of the housing (11) and the protection part (12), configurations that interfere with each other may be provided. The housing (11) may include a first housing projection (113) and a second housing projection (114) that interfere with the protection part (12). The protection part (12) may include a first protection arm (123) that interferes with the first housing projection (113) and a second protection arm (124) that interferes with the second housing projection (114). The first housing projection (113) and the second housing projection (114) may be maintained in a fixed state while the interference state with the first protection arm (123) and the second protection arm (124) is switched. Meanwhile, the first protective arm (123) and the second protective arm (124) may be deformed while the interference state with the first housing projection (113) and the second housing projection (114) is switched. The connector assembly may have improved durability by applying a configuration that is deformed while the interference state is switched to a relatively easy-to-maintain protective part (12).

[0036] The first housing (11) can accommodate a protective part (12). The first housing (11) may include a housing base (111), a housing body (112) formed protruding from the housing base (111), a first housing projection (113) formed protruding from the housing base (111) and provided on the inside of the housing body (112), and a second housing projection (114) formed protruding from the housing base (111) and provided on the inside of the housing body (112).

[0037] The housing base (111) may have a plate shape. The housing base (111) may be provided with a plurality of housing holes (111a) for supporting a plurality of terminals (not shown). The plurality of housing holes (111a) may be formed through in the z-axis direction. The plurality of housing holes (111a) may assist in aligning and arranging a plurality of terminals.

[0038] The housing body (112) may be formed to protrude in the z-axis direction from the housing base (111). The housing body (112) may have a shape having a hollow on the inside. The housing body (112) may surround a plurality of terminals (not shown). The housing body (112) may include a first housing body side wall (112a) in which the normal of the inner surface faces the y-axis direction, and a second housing body side wall (112b) in which the normal of the inner surface faces the x-axis direction. The first housing body side wall (112a) and the second housing body side wall (112b) may meet perpendicularly to each other.

[0039] The first housing projection (113) can support the protection part (12). When no external force is applied to the protection part (12), the first housing projection (113) supports the protection part (12) and assists the protection part (12) to be positioned spaced apart from the housing base (111) in the z-axis direction. When an external force is applied to the protection part (12) and the part of the protection part (12) that is engaged with the first housing projection (113) is deformed, the engagement state of the protection part (12) with respect to the first housing projection (113) can be released. In this case, the protection part (12) can pass through the first housing projection (113). The operation of the first housing projection (113) and the first protection arm (123) will be described in detail with reference to FIGS. 6 to 9.

[0040] The first housing projection (113) may be formed to protrude in the z-axis direction from the housing base (111). The first housing projection (113) may be provided on the inner side of the housing body (112). For example, the first housing projection (113) may be provided in a state of close contact with the inner surface of the housing body (112). For example, the first housing projection (113) may be formed integrally with the housing base (111) and the housing body (112). According to such a structure, since no space is provided between the first housing projection (113) and the housing body (112), the size of the first housing (11) can be configured compactly.

[0041] The first housing protrusions (113) may be provided symmetrically on opposite sides with respect to the center of the first housing (11). For example, the first housing protrusions (113) may be provided on the +y side and the -y side, respectively, with respect to the center of the first housing (11).

[0042] The first housing protrusions (113a, 113b) may be provided as a pair facing each other. Each of the pair of first housing protrusions (113a, 113b) may include a first housing protrusion body (1131a, 1131b) formed protruding from the housing base (111), and a first housing protrusion head (1132a, 1132b) formed protruding from the first housing protrusion body (1131a, 1131b).

[0043] For example, any one of the first housing protrusions (113a, 113b) may include a first housing protrusion body (1131a) formed protruding in the z-axis direction from the housing base (111), and a first housing protrusion head (1132a) formed protruding in the x-axis direction from the first housing protrusion body (1131a). Any one of the first housing protrusions (113b) may include a first housing protrusion body (1131b) formed protruding in the z-axis direction from the housing base (111), and a first housing protrusion head (1132b) formed protruding in the x-axis direction from the first housing protrusion body (1131b). The first housing protrusion head (1132a) and the first housing protrusion head (1132b) may be formed to protrude in a direction close to each other.

[0044] The second housing projection (114) can assist in preventing the second protective arm (124) of the protective part (12) from deforming when the protective part (12) is in a lowered position. The second housing projection (114) can be formed lower than the height of the housing body (112). While the protective part (12) is supported by the first housing projection (113), the second housing projection (114) can be spaced apart from the second protective arm (124). When the protective part (14) is no longer supported by the first housing projection (113) and descends along the housing body (112), the second housing projection (114) can cover the second protective arm (124) so ​​that the second protective arm (124) does not deform outwardly. The second protective arm (124) is supported by the second housing projection (114) and prevented from being deformed while the protective part (12) rises a certain distance from the housing base (111), and when the protective part (12) rises beyond a certain distance, it is not supported by the second housing projection (114) and is deformed, thereby allowing the insertion part (2, second connector) to be easily separated from the protective part (12). The operation of the second housing projection (114) and the second protective arm (124) will be explained in detail with reference to FIGS. 10 to 13.

[0045] The second housing projection (114) may be formed to protrude in the z-axis direction from the housing base (111). The second housing projection (114) may be provided on the inner side of the housing body (112). For example, the second housing projection (114) may be provided in a state of close contact with the inner surface of the housing body (112). For example, the second housing projection (114) may be formed integrally with the housing base (111) and the housing body (112).

[0046] The protective part (12) may include a protective base (121) facing a housing base (111), a protective body (122) formed protruding from the protective base (121), a first protective arm (123) extending from the protective body (122) and capable of being caught on a first housing projection (113), and a second protective arm (124) extending from the protective body (122) and capable of being caught on a second housing projection (114).

[0047] The protective base (121) may have a plate shape. The protective base (121) may be provided in a state approximately parallel to the housing base (111). The protective base (121) may have a plurality of protective holes (121a) for supporting a plurality of terminals (not shown). The plurality of protective holes (121a) may be formed through in the z-axis direction. The plurality of protective holes (121a) may assist in aligning and providing a plurality of terminals. A terminal (not shown) may have one side supported by the housing hole (111a) and the other side supported by the protective hole (121a).

[0048] The protective body (122) may be formed to protrude in the z-axis direction from the protective base (121). The protective body (122) may have a shape having a hollow on the inside. The protective body (122) may surround a plurality of terminals (not shown). The protective body (122) may include a first protective body sidewall (122a) in which the normal of the inner surface faces the y-axis direction, and a second protective body sidewall (122b) in which the normal of the inner surface faces the x-axis direction. The first protective body sidewall (122a) and the second protective body sidewall (122b) may meet perpendicularly to each other.

[0049] The first protective arm (123) may be formed protruding from the protective body (122). The first protective arm (123) may be formed protruding in the -z direction from the upper part of the protective body (122). The first protective arm (123) may move around the part connected to the protective body (122). The first protective arm (123) may be deformed by an external force. The first protective arm (123) may be provided in a state of being engaged with the first housing projection (113). When an external force is applied to the first protective arm (123) and it is deformed, the engaged state of the first protective arm (123) with respect to the first housing projection (113) may be released.

[0050] The first protective arm (123) may protrude in the z-axis direction from, for example, the upper part of the first protective body side wall (122a). The first protective arm (123) may be movable around the y-axis by an external force. In other words, the lower part of the first protective arm (123) may be movable in the x-axis direction. The first protective arm (123) may be in a state of being caught on the first housing projection (113) and may be moved in the x-axis direction to be separated from the first housing projection (113).

[0051] The first protective arms (123a, 123b) may be provided as a pair. When the pair of first protective arms (123a, 123b) are deformed by interfering with the insert part (2), they may deform in opposite directions. For example, while the lower end of one of the first protective arms (123a) of the pair of first protective arms (123a, 123b) is deformed in the +x direction, the lower end of the other first protective arm (123b) may deform in the -x direction. One of the first protective arms (123a) of the pair of first protective arms (123a, 123b) may be caught on the first housing projection (113a), and the other first protective arm (123b) may be caught on the first housing projection (113b).

[0052] The second protective arm (124) may be formed protruding from the protective body (122). The second protective arm (124) may be formed protruding in the -z direction from the upper part of the protective body (122). The second protective arm (124) may move around the part connected to the protective body (122). The second protective arm (124) may include a pair of second protective arm bodies (1241) formed in the z-axis direction and a second protective arm head (1242) connecting the pair of second protective arm bodies (1241). The second protective arm head (1242) may be provided in the y-axis direction.

[0053] It should be noted that the second connector (2) is also referred to as the insertion part (2) in this specification. The insertion part (2) may include an insertion body (21) that can be inserted into the inner side of the protection part (12), a first insertion projection (22) that is formed protruding from the insertion body (21) and interferes with the first protection arm (123), a second insertion projection (23) that is formed protruding from the insertion body (21) and interferes with the second protection arm (123), an insertion rib (24) that is formed protruding from the upper edge portion of the insertion body (21) and can press the upper end of the protection body (122), and an insertion guide (25) that is formed on the upper part of the insertion body (21) and can slide in a state of surface contact with the protection body (122).

[0054] The insertion body (21) may include a first surface (21a) facing the first protective arm (123) with a normal line in the y-axis direction, and a second surface (21b) facing the second protective arm (124) with a normal line in the x-axis direction.

[0055] The first insertion projection (22) can deform the first protective arm (123) while the insertion body (21) is inserted into the inner side of the protective part (12), thereby releasing the locking state of the first protective arm (123).

[0056] The first insertion projection (22) is formed protruding from the first surface (21a), and the first protective arm (123) is movable in a direction intersecting the normal direction of the first surface (21a). For example, the first protective arm (123) is movable in the x-axis direction intersecting the y-axis direction, which is the normal direction of the first surface (21a). The first protective arm (123) is movable around the y-axis. For example, the first protective arm (123) is movable in a direction parallel to the first surface (21a). According to such movement, there is no need to provide a separate space for the first protective arm (123) to move, so the housing body (112) and the protective body (122) can be brought into close contact, and the first connector (1) can have a compact structure.

[0057] The first insertion projection (22) and the first protective arm (123) may each be provided as a pair. The pair of first insertion projections (22) may be spaced apart from each other in the x-axis direction. The pair of first insertion projections (22) may deform in a direction that brings the pair of first protective arms (123) closer together. For example, the pair of first protective arms (123) may come into contact with each other when they are as close as possible. According to such a structure, excessive deformation of the first protective arm (123) can be prevented.

[0058] FIG. 4 is a partial enlarged view illustrating a connector assembly according to one embodiment, and FIG. 5 is a perspective view illustrating a first protective arm according to one embodiment.

[0059] It should be noted that FIGS. 3 and 4 illustrate the first protective arm (123) as viewed from the inside of the protective part (12), whereas FIG. 5 illustrates the first protective arm (123) as viewed from the outside of the protective part (12).

[0060] Referring to FIGS. 4 and 5, the first protective arm (123) may include a first protective arm body (1231) extending from the protective body (122) in a first direction, for example, in the z-axis direction, and a first protective arm head (1232) protruding from the first protective arm body (1231) in a second direction, for example, in the x-axis direction, intersecting the first direction.

[0061] The protective base (121) may be provided with a cutting part (121a) for exposing the first protective arm (123) to the first housing projection (113) with respect to the +z direction. The first protective arm (123) may be located relatively inward relative to the outermost edge portion of the protective body (122). Due to the cutting part (121a), the protective base (121) may not interfere with the first housing projection (113) while the protective body (122) is descending. For example, the cutting part (121a) may be a portion formed by being recessed from the edge portion of the protective base (121) toward the center. The width of the cutting part (121a) in the x-axis direction may be wider than the spacing of a pair of first housing projections (113). The cutting part (121a) may be sufficient to accommodate a pair of first housing projections (113). According to this shape, the protective body (122) is in close contact with the housing body (112), and the protective base (121) can accommodate a pair of first housing protrusions (113), so the connector assembly can be configured compactly. The width of the cutting part (121a) in the x-axis direction may be wider than the gap between the pair of first protective arms (123). The pair of first protective arms (123) can move within the area exposed by the cutting part (121a).

[0062] The first protective arm body (1231) is movable around the y-axis. The first protective arm body (1231) is movable in the x-axis direction. The first protective arm body (1231) is movable in a direction parallel to the outer surface of the insertion body (21), where the normal direction is the y-axis direction. The first protective arm body (1231) is movable in a direction parallel to the inner surface of the housing body (112), where the normal direction is the y-axis direction.

[0063] The first protective arm head (1232) may be provided in a state of being engaged with the first housing projection (113) when no external force is applied. The first protective arm head (1232) may interfere with the first insertion projection (see FIG. 1). The portion of the first protective arm head (1232) supported by the first housing projection (113) may not overlap with the portion of the first protective arm head that interferes with the first insertion projection (see FIG. 1) in the z-axis direction. According to such a structure, the first insertion projection (see FIG. 1) may not be engaged with the first housing projection (113) while the insertion body (21) is descending.

[0064] The first protective arm head (1232) may include a first inclined part (1232a) having a height that protrudes from the first protective arm body (1231) as it moves toward the insertion direction of the insertion body, for example, the z-axis direction, a head body part (1232b) having a support surface (1232d) that contacts the first housing projection (113), and a second inclined part (1232c) having a height that protrudes from the first protective arm body (1231) as it moves toward the insertion direction of the insertion body, for example, the z-axis direction, and may not overlap the first housing projection (113).

[0065] The first inclined part (1232a) may have an interference surface (A) that contacts the first insertion projection (122). The interference surface (A) may overlap the second inclined part (1232c) in the z-axis direction. The first inclined part (1232a) may have a first width (d1) that is approximately equal to the width of the first protective arm body (1231). The second inclined part (1232c) may have a second width (d2) that is smaller than the width of the first inclined part (1232a).

[0066] The second inclined part (1232c) can interfere with the first insertion projection (see FIG. 1) while the first insertion projection (see FIG. 1) is rising.

[0067] FIGS. 6 to 9 are cross-sectional views illustrating the interaction between a first housing projection and a first protective arm of a connector assembly according to one embodiment.

[0068] Referring to FIGS. 6 through 9, the protective part (12) may be provided within the housing (11). The protective base (121) may be provided facing the housing base (111) but spaced apart in the z-axis direction. The first protective arm (123) may be supported by the first housing projection (113). The protective body (122) is slidable along the housing body (112).

[0069] While the insertion part (2) is being inserted into the protective part (12), the first insertion projection (22) can release the locking state of the first protective arm (123). The support state of the first protective arm (123) with respect to the first housing projection (113) can be released by the first insertion projection (22). The insertion guide (25) can slide along the first protective arm (123). The insertion rib (24) can press the upper edge portion of the protective body (122) to lower the protective part (12).

[0070] After the support state of the first protective arm (123) for the first housing projection (113) is released, the insertion rib (24) can lower the protective part (12) until the protective base (121) of the protective part (12) contacts the housing base (111).

[0071] FIGS. 10 to 13 are cross-sectional views illustrating the interaction between a second housing projection and a second protective arm of a connector assembly according to one embodiment.

[0072] Referring to FIGS. 10 to 13, the protective part (12) may be provided within the housing (11). The protective base (121) may face the housing base (111). When the insertion part (2) is fully inserted, the second insertion projection (23) may be located below the second protective arm (124).

[0073] While the insert part (2) is rising, that is, while the insert part (2) is separated from the protection part (12), the second insert projection (23) can press the second protection arm head (1242) of the second protection arm (124) in the +z direction to raise the protection part (12). While the second protection arm head (1242) is in a position where it overlaps with the second housing projection (114) in the x-axis direction, the movement of the second protection arm body (1241) in the x-axis direction may be restricted by the second housing projection (114). The protection body (122) can rise along the housing body (112) in the +z direction.

[0074] Meanwhile, when the insertion part (2) rises beyond a certain distance, for example, when the second protective arm head (1242) rises to a position where it does not overlap the second housing projection (114) in the x-axis direction, the second protective arm body (1241) can be deformed outwardly by receiving an outward force from the second insertion projection (23). In this case, the second insertion projection (23) can pass through the second protective arm head (1242), and as a result, the insertion part (2) can be separated from the protective part.

[0075] Although the embodiments have been described above with reference to the limited drawings, those skilled in the art can apply various technical modifications and variations based thereon. For example, suitable results may be achieved even if the described techniques are performed in a different order than described, and / or if the components of the described system, structure, device, circuit, etc. are combined or assembled in a form different from described, or replaced or substituted by other components or equivalents.

[0076] Therefore, other implementations, other embodiments, and equivalents to the claims also fall within the scope of the claims set forth below.
