DETAILED DESCRIPTION
[0009] [Description of Embodiments of the Invention] First, embodiments of the present invention will be described by way of examples. The connector of the present invention, The locking device is configured to lock the locking cam of the locking cam and the locking cam of the locking cam, wherein the locking cam is configured to lock the locking cam of the locking cam and the locking cam of the locking cam.
[0010] According to the configuration of (1) above, the top end of the terminal locking portion of the stopper is covered and protected by the protective wall from both the left and right sides. In addition, when a force to rotate the main body of the stopper acts on the stopper, the concave portion receives the convex portion, which can limit the displacement of the protective wall in the vertical direction, and can also limit the displacement of the terminal locking portion located on the left and right inner sides of the protective wall in the vertical direction. As a result, the stability of the locking of the terminal locking portion relative to the terminal part can be ensured.
[0011] (2) In the connector described in (1) above, the convex portion may be configured to contact the inner surface of the concave portion in a state where the position of the convex portion is restricted in at least one direction of the vertical direction at the temporary locking position.
[0012] According to the above-mentioned structure (2), when the stopper is located at the temporary locking position, the protective wall and thus the terminal locking portion can be restricted from shifting in at least one direction of the upward and downward directions, which can further improve the locking stability of the terminal locking portion relative to the terminal part.
[0013] (3) In the connector described in (1) or (2) above, the convex portion may be configured to contact the inner surface of the concave portion in a state where the convex portion is restricted from being displaced obliquely forward at the final locking position.
[0014] According to the configuration of (3) above, when the stopper is located at the final locking position, the protective wall and thus the terminal locking portion are restricted from being displaced obliquely forward.
[0015] (4) In the connector described in any one of (1) to (3) above, the convex portion may be fitted with the entire concave portion at the permanent locking position.
[0016] According to the configuration of (4) above, when the stopper is located at the formal locking position, the protective wall and thus the terminal locking portion can be more reliably restricted from vertical displacement, and a structure can be formed that is less likely to cause rattling between the housing and the stopper.
[0017] [Details of Embodiments of the Invention] Specific examples of the present invention are described below with reference to the drawings. The present invention is not limited to the examples, but is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.
[0018] <Implementation Method 1> like Figure 1 As shown, the connector 10 of the first embodiment includes a terminal part 50, a housing 20 for accommodating the terminal part 50, and a stopper 60 disposed on the housing 20 so as to be movable between a temporary locking position and a formal locking position. Figure 4 As shown in FIG. 1 , the housing 20 can be mated with the counterpart housing 100. In addition, in the following description, regarding the front-back direction, the direction in which the housing 20 and the counterpart housing 100 are mated is referred to as the front. Figure 1 and Figure 4 The up and down directions are taken as the reference. Figure 1 In the figure, the front is indicated by X, the right is indicated by Y, and the top is indicated by Z. These direction references are for convenience and are not necessarily consistent with the direction references when the connector 10 is mounted on a vehicle, etc. Therefore, the bottom is not limited to the gravity direction.
[0019] (Housing 20 and terminal parts 50) The housing 20 is made of synthetic resin, such as Figure 1 As shown, the housing body 21 is block-shaped and includes a cylindrical cover portion 22 that protrudes forward from the housing body 21 .
[0020] like Figure 4 As shown, the counterpart housing 100 is fitted into the cover 22. A locking portion 24 is protrudingly formed on the upper surface of the inner wall of the cover 22. The counterpart housing 100 is locked by the locking portion 24, so that the housing 20 and the counterpart housing 100 are kept in a fitted state.
[0021] A plurality of cavities 25 extending in the front-rear direction are formed in the housing body 21. Figure 3 As shown, the cavities 25 are arranged in a left-right direction inside the housing body 21. Figure 1 and Figure 4 As shown, an elastically deformable lance 26 is protrudingly formed on the lower surface of the inner wall of each cavity 25 .
[0022] The terminal part 50 is inserted into the cavity 25 from the rear. The terminal part 50 is made of conductive metal and has a box part 51, a protruding piece 52 protruding forward from the box part 51, and a cylindrical part 53 located behind the box part 51. The box part 51 is locked with the lance 26. The terminal part 50 is initially prevented from being separated from the cavity 25 by the lance 26. The protruding piece 52 is arranged to protrude into the cover part 22. Figure 4 As shown, the terminal part 50 is electrically connected to the mating terminal part 150 by inserting the tab 52 into the female mating terminal part 150 mounted on the mating housing 100. The cylindrical part 53 is electrically and mechanically connected to the terminal end of the electric wire W.
[0023] A stopper mounting hole 27 is formed in an opening at the rear portion of the lower surface of the housing body 21. The stopper mounting hole 27 communicates with each cavity 25. In the stopper mounting hole 27, a stopper main body 62 of the stopper 60 described later can be inserted.
[0024] like Figure 2 As shown in FIG. 1 , guide portions 28 are recessed on the side surfaces of the left and right sides of the housing body 21. The guide portions 28 are formed at the rear portion of the housing body 21 in the same manner as the stopper mounting hole 27. A side wall 61 of the stopper 60 described later is fitted into the guide portions 28. The upper and lower end edges of the guide portions 28 are respectively formed as an upper guide surface 29 and a lower guide surface 31 for guiding the movement of the stopper 60. The upper guide surface 29 and the lower guide surface 31 are inclined upward toward the front. The lower guide surface 31 forms the upper surface of a guide rib 32 extending obliquely forward.
[0025] The rear edge of the guide portion 28 is configured as a rear stop surface 33 that restricts the side wall 61 of the stop body 60 in the temporary stop position from falling off to the rear. The rear stop surface 33 is formed along the up-down direction. The rear end of the upper guide surface 29 and the upper end of the rear stop surface 33 are connected to each other. The front edge of the guide portion 28 is configured as a front stop surface 34 (see FIG. 1 ) that restricts the side wall 61 of the stop body 60 from moving forward (obliquely forward). Figure 5 ). The front stop surface 34 is formed along the up-down direction. Figure 2 As shown, the front end of the guide rib 32 and the lower end of the front stop surface 34 are connected to each other.
[0026] A retaining portion 35 is protrudingly formed on the inner bottom surface of the guide portion 28 in the side surface of the housing body 21. The rear surface of the retaining portion 35 is inclined toward the left and right sides and obliquely downward. Figure 2 As shown, the side wall 61 of the stopper body 60 is in contact with the rear surface of the holding portion 35 .
[0027] Concave portions 36 are formed on the side surfaces of both left and right sides of the housing body 21. The concave portions 36 receive convex portions 69 of the stopper body 60, which will be described later, and thus restrict the position of the protection wall 64 including the convex portions 69 in the vertical direction.
[0028] The recess 36 is recessed in the side of the housing body 21. The rear portion of the recess 36 is connected to the stopper mounting hole 27, and an introduction port 37 is opened on the lower surface of the housing body 21. The front portion of the recess 36 is separated from the cavity 25 adjacent to the front portion of the recess 36 by a thin-walled side portion 38.
[0029] The concave portion 36 is formed into a shape that extends obliquely forward as a whole from the introduction port 37 upward. The end edge located on the rear side of the concave portion 36 is formed as an upper inclined surface 39 that tilts forward upward. The upper inclined surface 39 can contact the convex portion 69 from above. The end edge located on the front side of the concave portion 36 is also formed as a lower inclined surface 41 that tilts forward upward. The lower inclined surface 41 can contact the convex portion 69 from below. The upper inclined surface 39 and the lower inclined surface 41 are arranged opposite to each other in parallel. The end edge located on the upper side of the concave portion 36 is formed as an inner end surface 42 that extends linearly in the front-to-back direction. The inner end surface 42 can contact the upper end surface of the convex portion 69 from above. The rear end of the inner end surface 42 and the upper end of the upper inclined surface 39 intersect each other at an obtuse angle. The front end of the inner end surface 42 and the upper end of the lower inclined surface 41 intersect each other at an acute angle. The intersection of the front end of the inner end surface 42 and the upper end of the lower inclined surface 41 forms a curved shape (R shape).
[0030] (Stop body 60) The stopper 60 is made of synthetic resin, such as Figure 7 and Figure 8 As shown, it has a pair of side walls 61 opposite to each other in the left-right direction, a stop body main body 62 arranged between the side walls 61, a pair of terminal locking parts 63 protruding from the stop body main body 62, and a pair of protective walls 64 connected to the stop body main body 62 and covering each terminal locking part 63 from the left and right sides.
[0031] like Fig. 9 As shown, each side wall 61 is shaped so that the wall surface stands in the left-right direction and is movably embedded in the guide portion 28 of the housing body 21 (see Figure 2 and Figure 5 A held portion 65 is formed through each side wall 61. Figure 5As shown, in the formal locking position, the retaining portion 35 is engaged with the inner portion of the retained portion 65. The rear end surface of each side wall 61 is arranged along the vertical direction, and in the temporary locking position, it is opposite to the rear stop surface 33 of the housing body 21 so as to be contactable (see Figure 2 The upper portion of the front end surface of each side wall 61 is tilted upward toward the rear, and is in contact with the rear surface of the temporary locking position holding portion 35. The upper and lower middle portions of the front end surface of each side wall 61 are arranged along the vertical direction, and are in contact with the front stop surface 34 of the housing body 21 in the formal locking position (refer to Figure 5 ).
[0032] The rear portion of the upper end surface of each side wall 61 is inclined upward toward the front and is slidably opposed to the upper guide surface 29 (see Figure 2 and Figure 5 In addition, a guide groove 66 (see FIG. 1 ) that can be engaged with the guide rib 32 is provided on the inner surface of each side wall 61 (the mutually opposing surface of each side wall 61). Figure 7 ). A guided portion 67 that can slide on the guide rib 32 is also protrudingly formed at the lower portion of the front end surface of each side wall 61. Figure 2 and Figure 5 As shown, the upper end surface of the guided portion 67 is continuous with the lower groove surface of the guide groove 66 .
[0033] like Figure 7 and Figure 8 As shown, the stopper body 62 extends in the left-right direction between the lower ends of the side walls 61 and constitutes the bottom wall portion of the stopper body 60. Figure 8 As shown, the stopper body main body 62 has a base portion 68 that protrudes forward from between the lower end portions of the side walls 61 . like Figure 8 As shown in FIG. 1 , each terminal stopper 63 is arranged in a left-right direction and protrudes from the upper surface of the base 68. Each terminal stopper 63 can be inserted into the stopper mounting hole 27 together with the stopper body 62. The top end (front end) of each terminal stopper 63 protrudes forward from the base 68. Figure 4 As shown, the front end surface of the terminal locking portion 63 is arranged along the up-down direction, and is opposed to the rear end surface of the box portion 51 of the terminal fitting 50 in a contactable manner at the full locking position.
[0034] like Figure 8As shown, each protective wall 64 is protrudingly provided on the side surfaces of the left and right sides of the base 68, and is arranged in pairs on the left and right sides of each terminal stopper 63. A pair of convex portions 69 are protrudingly formed at the left and right ends of each protective wall 64. Each convex portion 69 is formed in a plate shape with the plate surface facing the left and right directions, and is arranged at a distance from the top end of each terminal stopper 63 and on the left and right outer sides than each terminal stopper 63. Each convex portion 69 has an entirety that covers the top end (the portion protruding forward from the base 68) of each terminal stopper 63 located on the left and right inner sides, and a portion that protrudes forward than the front end surface of each terminal stopper 63.
[0035] like Fig. 9 As shown, the convex portion 69 is shaped to extend obliquely forward from the lower end of the protective wall 64 upward. The rear end surface of the convex portion 69 is inclined forward upward and slidably faces the upper inclined surface 39 of the concave portion 36 (see Figure 5 ). The front end face of the convex portion 69 is inclined forward and upward in parallel with the rear end face of the convex portion 69, and is slidably opposed to the lower inclined surface 41 of the recess 36. The upper end face of the convex portion 69 extends in a straight line along the front-to-back direction, and is in abutting contact with the inner end face 42 of the recess 36. The rear end of the upper end face of the convex portion 69 and the upper end of the rear end face intersect each other at an obtuse angle. The front end of the upper end face of the convex portion 69 and the upper end of the front end face intersect each other at an acute angle. The intersection of the front end of the upper end face of the convex portion 69 and the upper end of the front end face forms a curved shape (R shape). In short, the convex portion 69 forms a shape corresponding to the recess 36, and is integrally fitted with the recess 36 in the formal locking position.
[0036] (Function of connector 10) Before the terminal part 50 is inserted into the cavity 25, the stopper 60 is arranged at a temporary stop position relative to the housing 20. At the temporary stop position, the guide rib 32 of the housing 20 is embedded in the guide groove 66 of the stopper 60. Figure 2 As shown, the upper portion of the front end surface of the side wall 61 contacts the rear surface of the retaining portion 35, thereby limiting the movement of the stopper 60 from the temporary stop position to the formal stop position. The rear end surface of the side wall 61 contacts the rear stop surface 33 of the guide portion 28, thereby limiting the stopper 60 from falling off backward from the temporary stop position. The upper end surface of the guided portion 67 contacts the lower guide surface 31, thereby limiting the stopper 60 from falling off downward from the temporary stop position. As a result, the stopper 60 is maintained at the temporary stop position relative to the housing 20. As shown in FIG. Figure 1 As shown, at the temporary locking position, the terminal locking portion 63 is arranged to be retracted from the insertion path of the terminal fitting 50 into the cavity 25. Therefore, when the stopper 60 is at the temporary locking position, the terminal fitting 50 is allowed to be inserted into the cavity 25.
[0037] The terminal part 50 is connected to the terminal end of the wire W, and the tip of the protrusion 52 is directed forward while being inserted into the cavity 25 of the housing 20 from the rear. When the terminal part 50 is inserted into the cavity 25 at a proper depth, the lance 26 is locked with the box part 51, and the terminal part 50 is initially restricted from falling out of the cavity 25.
[0038] like Figure 2 As shown, at the temporary stop position, the top end of the convex portion 69 enters the concave portion 36, and the top end side of the front end surface of the convex portion 69 is arranged in a manner of contacting along the lower inclined surface 41 of the concave portion 36. Assuming that a force is applied to the stopper 60 at the temporary stop position to rotate the side wall 61 obliquely forward and downward, the terminal stopper 63 becomes a state capable of shifting downward within the movable range of the side wall 61 in the guide portion 28. However, in the case of the first embodiment, the top end side of the front end surface of the convex portion 69 contacts the lower inclined surface 41 of the concave portion 36, thereby suppressing the displacement of the convex portion 69 and thus each terminal stopper 63 downward.
[0039] After each terminal part 50 is inserted into each cavity 25, the stopper 60 is pressed toward the formal locking position. When the pressing force is applied to the stopper 60, each side wall 61 elastically deforms while straddling the holding portion 35, the groove surface of the guide groove 66 and the upper end surface of the guided portion 67 slide along the guide rib 32, and the rear portion of the upper end surface of each side wall 61 slides with the upper guide surface 29, thereby guiding each side wall 61 to move obliquely forward relative to the housing 20.
[0040] In addition, the convex portion 69 slides with the upper inclined surface 39 and the lower inclined surface 41 of the concave portion 36, thereby guiding the protective wall 64 to move obliquely forward relative to the housing 20. Even if a force that attempts to rotate the side wall 61 acts on the stopper 60 moving toward the formal locking position, the convex portion 69 is sandwiched between the upper inclined surface 39 and the lower inclined surface 41 of the concave portion 36 in the vertical direction, so that the rotation of the convex portion 69 and the side wall 61 can be suppressed.
[0041] When the stopper 60 reaches the formal stop position, Figure 5 As shown, the lower portion of the front end surface of the side wall 61 contacts the front stop surface 34 of the guide portion 28, thereby limiting further movement (movement diagonally forward) of the stopper 60. In addition, the retaining portion 35 is embedded in the retained portion 65 of each side wall 61, also limiting the movement of the stopper 60 diagonally backward. As a result, the stopper 60 is retained at the formal locking position relative to the housing 20.
[0042] like Figure 4 As shown, in the formal locking position, the terminal locking portion 63 is configured to be locked with the box portion 51 of the terminal part 50 from the rear, and the terminal part 50 is restricted from falling off from the cavity 25. Figure 6 As shown, the opening of the stopper body mounting hole 27 is closed by the base 68 .
[0043] In addition, if Figure 5 As shown, in the formal locking position, the top end of the protrusion 69 is embedded in the acute-angled V-shaped space 43 where the inner end surface 42 and the lower inclined surface 41 of the recess 36 intersect, and the upper end surface of the protrusion 69 is in contact with the inner end surface 42 of the recess 36. In addition, continuing from the movement process of the stopper 60, the rear end surface of the protrusion 69 is in contact with the upper inclined surface 39 of the recess 36, and the front end surface of the protrusion 69 is in contact with the lower inclined surface 41 of the recess 36.
[0044] Assuming that a force is applied to the stopper 60 in the formal locking position to rotate the side wall 61, the terminal locking portion 63 becomes displaceable within the movable range of the side wall 61 in the guide portion 28. However, in the case of the first embodiment, the front end face of the convex portion 69 contacts the lower inclined surface 41 of the concave portion 36, thereby limiting the downward displacement (rotational displacement) of each terminal locking portion 63. In addition, the rear end face of the convex portion 69 contacts the upper inclined surface 39 of the concave portion 36, and the front end face of the convex portion 69 contacts the lower inclined surface 41 of the concave portion 36, thereby also limiting the upward displacement (rotational displacement) of each terminal locking portion 63. As a result, the state in which each terminal locking portion 63 can be locked with the box portion 51 of each terminal part 50 can be maintained.
[0045] However, the terminal part 50 sometimes does not insert into the cavity 25 at the regular depth and stays at the half-insertion position. In this case, during the process of the stopper 60 moving obliquely forward from the temporary locking position to the formal locking position, the terminal locking portion 63 abuts against the box portion 51 of the terminal part 50 at the half-insertion position from the rear. When the stopper 60 moves further toward the formal locking position, the terminal part 50 is pressed by the stopper 60 and the cavity 25 moves forward. When the stopper 60 reaches the formal locking position, the terminal part 50 is pressed by the terminal locking portion 63 and inserted into the cavity 25 at the regular depth. Therefore, it is possible to prevent the terminal part 50 from staying at the half-insertion position.
[0046] The stopper 60 presses each terminal part 50 at the half-inserted position during the movement, thereby applying the above-mentioned force in the rotational direction to the stopper 60. In the case of the first embodiment, as described above, since the convex portion 69 is engaged with the concave portion 36 in a state where the position is restricted in the vertical direction, the terminal locking portion 63 can press the terminal part 50 without shifting in the vertical direction. As a result, the terminal part 50 is stably accommodated in the cavity 25 at a regular depth.
[0047] As described above, the connector 10 of the first embodiment includes: a housing 20 formed with a cavity 25 extending in the front-rear direction; a terminal part 50 housed in the cavity 25 with the tip facing forward; and a stopper 60 arranged on the housing 20 so as to be movable between a temporary locking position and a formal locking position. The stopper 60 includes a stopper body 62 and a terminal locking portion 63 protruding forward from the stopper body 62. The stopper 60 is configured such that the tip of the terminal locking portion 63 faces the terminal part 50 from the rear when the stopper 60 moves obliquely forward from the temporary locking position to the formal locking position relative to the housing 20. Furthermore, the stopper 60 includes a protective wall 64 covering the tip of the terminal locking portion 63 from the left and right sides across the terminal locking portion 63. The protective wall 64 includes a convex portion 69 protruding obliquely forward. Furthermore, the housing 20 has a recessed portion 36 that extends obliquely forward and receives the protruding portion 69 in a state where the position of the protruding portion 69 is restricted in the up-down direction at the formal locking position.
[0048] Thus, the top end of the terminal locking portion 63 of the stopper 60 is covered and protected from both left and right sides by the protective wall 64. In addition, when the electric wire W is pulled and a force for rotating the stopper main body 62 acts on the stopper 60, the concave portion 36 receives the convex portion 69, and the displacement of the protective wall 64 in the vertical direction can be restricted, and the displacement of the terminal locking portion 63 located on the left and right inner sides of the protective wall 64 in the vertical direction can also be restricted. As a result, the stability of the locking of the terminal locking portion 63 with respect to the terminal part 50 can be ensured.
[0049] In addition, the convex portion 69 is received by the concave portion 36, so that the movement of the stopper 60 relative to the housing 20 can be guided. Here, the convex portion 69 is configured to contact the lower inclined surface 41 as the inner surface of the concave portion 36 at the temporary locking position. Therefore, when the stopper 60 is located at the temporary locking position, the protective wall 64 and then the terminal locking portion 63 can be restricted from shifting downward, and the stability of the locking of the terminal locking portion 63 relative to the terminal part 50 can be further improved.
[0050] In the case of the first embodiment, the convex portion 69 is configured to contact the inner surface (the inner end surface 42 and the front inclined surface) of the V-shaped space 43 of the concave portion 36 in a state where the convex portion 69 is restricted from being displaced obliquely forward in the formal locking position. Therefore, when the stopper 60 is in the formal locking position, the protective wall 64 and thus the terminal locking portion 63 are also restricted from being displaced obliquely forward.
[0051] Furthermore, in the case of the first embodiment, the protrusion 69 is integrally engaged with the recess 36 at the formal locking position. Therefore, when the stopper 60 is at the formal locking position, the displacement of the protection wall 64 and thus the terminal locking portion 63 in the vertical direction can be further reliably restricted, and the connector 10 can be formed into a structure that is not easy to shake between the housing 20 and the stopper 60.
[0052] [Other embodiments of the present invention] It should be considered that the above-mentioned Embodiment 1 disclosed this time is an illustration and not restrictive in all aspects. like Fig.10 As shown, a convex stopper 45 may be formed on the side surface 38 of the housing 20 facing the recessed portion 36, and a concave stopped portion 72 that can be engaged with the stopper 45 from the outside at the formal locking position may be formed on the top end side of the left and right inner sides of the convex portion 69 of the stopper body 60. The stopped portion 72 is elastically engaged and locked with the stopper 45 at the formal locking position, so that the convex portion 69 can be more reliably restricted from being displaced relative to the recessed portion 36.
[0053] In the case of the first embodiment, the terminal component 50 is a male terminal having the protruding piece 52 protruding forward. On the other hand, the terminal component may be a female terminal without a protruding piece. When the terminal component is a female terminal, the cover portion can be omitted from the housing. According to the first embodiment, the recessed portion 36 receives the convex portion 69 in the entire range in which the stopper 60 moves between the temporary stop position and the formal stop position. In contrast, according to other embodiments, the recessed portion may not enter the convex portion when the stopper is at the temporary stop position. Any configuration is sufficient as long as the recessed portion receives the convex portion and restricts the position in the vertical direction when the stopper is at least at the formal stop position. According to the first embodiment, the convex portion 69 is configured to contact the lower inclined surface 41 of the concave portion 36 at the temporary stop position. In contrast, according to other embodiments, the convex portion may also be configured to contact the upper inclined surface of the concave portion at the temporary stop position. Alternatively, the convex portion may also be configured to contact both the upper inclined surface and the lower inclined surface of the concave portion at the temporary stop position.
