[0006] Patent Document 2: Japanese Patent Application Laid-Open No. 2001-351721

[0007] Patent Document 3: Japanese Patent Application Laid-Open No. 2005-322487 Summary of the Invention

[0008] Problems to be solved by the invention

[0009] In the case of Patent Document 1, the snap-fit ​​receiving portion is in a form in which the front and rear middle portions of the top plate are cut off, so there is a possibility that the strength of the first connector is reduced. In addition, there is also a possibility that foreign matter can invade the terminal storage chamber of the first connector through the snap-fit ​​receiving portion. In contrast, if the snap-fit ​​receiving portion is provided on the top plate of the first connector, the cut-off form of the top plate can be eliminated. However, when the snap-fit ​​receiving portion protrudes above the top plate and the engaging portion protrudes below the bottom plate, when the first connector and the second connector are in a combined state, a gap is formed between the top plate and the bottom plate, and in front and behind the engaging portion of the snap-fit ​​receiving portion and the engaging portion. Therefore, the problem of the amount of gap formed when the first connector and the second connector are in a combined state deteriorates the space efficiency.

[0010] Therefore, an object of the present disclosure is to provide a connector with good space efficiency.

[0011] Solutions to Problems

[0012] The connector disclosed herein comprises: a first shell having a first opposing surface and a first locking portion; and a second shell having a second opposing surface and a second locking portion, the first opposing surface and the second opposing surface being arranged to oppose each other, the first locking portion and the second locking portion being arranged at the rear portion of the first opposing surface and the rear portion of the second opposing surface, respectively, and being locked with each other to maintain the first shell and the second shell in a combined state, the first shell and the second shell having a recessed portion for receiving a protrusion provided on a mating shell serving as a mating partner in the combined state, the recessed portion being arranged between the front portion of the first opposing surface and the front portion of the second opposing surface, and being closer to the front side than the locking portions of the first locking portion and the second locking portion.

[0024] [Description of Embodiments of the Present Disclosure]

[0025] First, embodiments of the present disclosure will be described below.

[0026] The connector of the present disclosure,

[0027] (1) It comprises: a first shell having a first opposing surface and a first locking portion; and a second shell having a second opposing surface and a second locking portion, the first opposing surface and the second opposing surface are arranged to face each other, the first locking portion and the second locking portion are respectively arranged at the rear portion of the first opposing surface and the rear portion of the second opposing surface, and are locked with each other to maintain the first shell and the second shell in a combined state, the first shell and the second shell having a recessed portion for receiving a protrusion provided on a mating side shell as a mating partner in the combined state, the recessed portion being arranged between the front portion of the first opposing surface and the front portion of the second opposing surface, and being closer to the front side than the locking portion of the first locking portion and the second locking portion.

[0028] When the first and second housings are in the combined state, a gap is formed between the front portions of the first and second opposing surfaces, further forward than the engaging portions of the first and second locking portions. However, this gap serves as a recessed portion for receiving a protrusion provided on the mating housing. Therefore, the above-described configuration allows for effective utilization of the space between the first and second opposing surfaces.

[0029] (2) Preferably, the recessed portion receives the protrusion of the mating housing for preventing jamming. The protrusion for preventing jamming is easily enlarged, and the recessed portion also tends to be enlarged. In this respect, according to the above configuration, since the recessed portion is arranged between the front portion of the first opposing surface and the front portion of the second opposing surface, a large space can be ensured along the surface direction of the first opposing surface and the second opposing surface. Therefore, the protrusion for preventing jamming can be enlarged in the surface direction of the first opposing surface and the second opposing surface.

[0030] (3) Preferably, the first locking portion and the second locking portion are sliding locks that lock movement along the surface direction of the first opposing surface and the second opposing surface. Since the first locking portion and the second locking portion are sliding locks, the first housing and the second housing can be prevented from being displaced in the surface direction. Therefore, according to this embodiment, the shape of the recess can be stably maintained.

[0031] (4) Preferably, at least one of the first shell and the second shell has a protrusion protruding rearward from the rear surface, the protrusion is arranged in a positioning hole of the sealing member, and at least one of the first locking portion and the second locking portion is arranged at a position connected to the root of the protrusion. By arranging the protrusion in the positioning hole of the sealing member, the sealing member can be arranged in a positioning manner on the rear surface side of at least one of the first shell and the second shell. Here, because the root of the protrusion is arranged in a position connected to at least one of the first locking portion and the second locking portion, space efficiency is further improved.

[0032] [Details of the embodiments of the present disclosure]

[0033] Specific examples of the connector disclosed herein will be described below with reference to the accompanying drawings. The present invention is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0034] <Overall structure of the connector>

[0035] like Figure 1 As shown, the connector of this embodiment includes an inner housing 10, a front member 11, a sealing member 12, a sealing ring 13, a rear retaining body 14, an outer housing 15, an outer shell 16, a wire cover 17, a rod 18, and a female terminal fitting 19. The inner housing 10, front member 11, rear retaining body 14, outer housing 15, outer shell 16, wire cover 17, and rod 18 are made of synthetic resin. The sealing member 12 and sealing ring 13 are made of rubber. The terminal fitting 19 is made of conductive metal.

[0036] The front member 11 is positioned to cover the front surface of the inner housing 10. The front member 11 has a retaining portion 21 to prevent the terminal fittings 19 from detaching from the inner housing 10. The sealing member 12 is a rubber plug sandwiched between the inner housing 10 and the rear retaining body 14. The sealing member 12 fluid-tightly seals the wires 20 connected to the terminal fittings 19 and also fluid-tightly seals the interior of the inner housing 10. The wires 20 are placed from the rear retaining body 14 into the wire cover 17 and then guided out of the cover 17 to the outside.

[0037] The outer shell 15 is arranged so as to surround the inner shell 10. The outer shell portion 16 constitutes the outer portion of the outer shell 15 and supports the rod 18. The rod 18 rotates around the position supported by the outer shell portion 16 when engaged with the counterpart housing 90. In this way, the connector and the counterpart housing 90 are fitted together. The sealing ring 13 is arranged in close contact with the outer peripheral surface of the outer shell 15. The counterpart housing 90 is fitted from the front between the outer shell portion 16 and the inner portion of the outer shell 15. The connector and the counterpart housing 90 are sealed liquid-tightly via the sealing ring 13. In addition, the inner shell 10 is configured to include a first shell 22 and a second shell 23.

[0038] The following describes in detail the structures of the mating side housing 90, the first housing 22, and the second housing 23. Furthermore, in this specification, the directions in which the first opposing surface 27 (described later) of the first housing 22 and the second opposing surface 43 (described later) of the second housing 23 face each other are defined as the "up-down direction" and the "height direction." That is, the height is synonymous with the up-down dimension. Furthermore, the direction intersecting, more specifically, orthogonal to, the "front-back direction" and the "up-down direction" is defined as the "width direction." Furthermore, the direction orthogonal to the "up-down direction" is defined as the "surface direction." Furthermore, in the accompanying drawings, the right side in the width direction when viewing the connector from the front is referred to as the "X direction," the top as the "Y direction," and the front as the "Z direction." Furthermore, in this embodiment, the right side when viewing the connector from the front corresponds to the "one side in the width direction," and the left side corresponds to the "other side in the width direction."

[0039] <Mate Side Housing>

[0040] The other side housing 90 is made of synthetic resin, such as Figure 1 As shown, the housing 91 has a square cylindrical shape. A plurality of male terminal parts 95 are protrudingly arranged within the housing 91. A protrusion 92 for preventing jamming is protrudingly arranged within the housing 91 in parallel with the male terminal parts 95. The protrusion 92 is formed in a plate-like shape along the width direction and protrudes from the inner bottom wall of the housing 91. The protrusion 92 is arranged within the housing 91, offset to one side from the center in the width direction. The top of the protrusion 92 is arranged forward of the top of each male terminal part 95. When the inner housing 10 is about to be fitted with the mating housing 90 in a tilted position in the front-to-back direction, the inner housing 10 contacts the top of the protrusion 92, thereby preventing the inner housing 10 from contacting the top of the male terminal parts 95. This prevents the top of the male terminal part 95 from being damaged or broken due to interference with the inner housing 10.

[0041] <First Shell>

[0042] like Figure 6 As shown in FIG. 1 , the first housing 22 is flat in the width direction as a whole. The first housing 22 is arranged below the second housing 23 in the inner housing 10 .

[0043] The first shell 22 has a plurality of first cavities 24 therein. Each first cavity 24 is provided through the first shell 22 in the front-to-back direction. Figure 1 As shown, the first housing 22 has a first lance 25 that protrudes forward from the inner wall of the first cavity 24. The terminal fitting 19 is inserted from the rear into the first cavity 24 of the first housing 22. The terminal fitting 19 is locked by the first lance 25 and prevented from being removed from the first cavity 24.

[0044] like Figure 6 and Figure 7As shown, the front portion of the upper wall of the first shell 22 is cut away. Each first lance 25 is exposed at the front portion of the upper wall of the first shell 22. The first shell 22 has a first slit groove 26 extending in the width direction between the front and rear portions. The first slit groove 26 is connected to each first cavity 24. Figure 1 As shown, the retaining portion 21 of the front member 11 is inserted into the first slit groove 26 from the side.

[0045] like Figure 6 As shown, the upper surface of the first housing 22 is formed as a first facing surface 27 that is flat along the width direction. The first lances 25 are exposed at the front of the first facing surface 27. A first slit groove 26 is opened between the front and rear portions of the first facing surface 27.

[0046] The first housing 22 has a low portion 28 located on one side in the width direction, and a high portion 29 located on the other side in the width direction and having a height greater than that of the low portion 28. A first step 31 in the height direction is formed between the high portion 29 and the low portion 28. The low portion 28 and the high portion 29 have different width dimensions. More specifically, the width dimension of the low portion 28 is greater than the width dimension of the high portion 29.

[0047] like Figure 6 As shown, the first cavities 24 are arranged in multiple rows in the width direction of the high-height portion 29 and the low-height portion 28, respectively, and are arranged in two upper and lower layers. The first cavities 24 formed in the high-height portion 29 have a larger diameter than the first cavities 24 formed in the low-height portion 28. Among the first cavities 24, the first cavities 24 formed in the upper layer of the high-height portion 29 have a portion that overlaps with the first step 31 in the upper direction.

[0048] A first locking portion 32 is provided protruding from the first opposing surface 27 at the rear of the low-height portion 28. The first locking portion 32 comprises: front and rear guide ribs 33 extending parallel to each other in the width direction; a pair of pressing portions 34 spaced apart at two positions midway in the width direction of the guide ribs 33, each projecting inwardly and facing each other; and a locking protrusion 35 protruding in a claw-like manner from the first opposing surface 27 at a position in the width direction center between the guide ribs 33 and near the first step 31.

[0049] like Figure 7As shown, the front guide rib 33 of the two guide ribs 33 is positioned adjacent to the first slit 26. The rear guide rib 33 is positioned along the rear end of the rear portion of the low-height portion 28, that is, the rear end of the first housing 22. The other widthwise ends of the two guide ribs 33 are connected to the first step 31. One widthwise end of the two guide ribs 33 is connected to the closing portion 36. The closing portion 36 is formed in a rectangular frame shape and protrudes from the first opposing surface 27 at the rear of the low-height portion 28. The upper surfaces of the two guide ribs 33 and the upper surfaces of the closing portion 36 are continuous without a step. The protrusion of each of the two guide ribs 33 and the closing portion 36 is greater than the protrusion of the locking protrusion 35 and less than the height of the first step 31. In other words, the height of the first step 31 is the protrusion from the first opposing surface 27.

[0050] The first housing 22 has a plurality of protrusions 37 protruding rearward from the rear surface. Each protrusion 37 is formed in a plate shape along the width direction. Each protrusion 37 includes a plurality of locking portion connecting protrusions 37A connected to the rear guide rib 33 on the upper rear surface of the low height portion 28. Figure 2 As shown, the locking portion connecting tabs 37A have their bases, i.e., their protruding ends, connected to the rear guide rib 33. Multiple locking portion connecting tabs 37A are spaced apart in the width direction. The locking portion connecting tabs 37A and the pressing portions 34 are alternately positioned in the width direction. Each tab 37 is inserted into a positioning hole 38 provided in the sealing member 12 in a positioned state. The sealing member 12 is positioned on the rear surface side of the first housing 22 using each tab 37.

[0051] like Figure 6 As shown, the first facing surface 27 of the high portion 29 is arranged one level higher than the first facing surface 27 of the low portion 28 via a first step 31. The first facing surface 27 of the rear portion of the high portion 29 is formed flat as a whole without any concavo-convex shapes.

[0052] <Second Shell>

[0053] like Figure 8 and Figure 9 As shown in FIG. 2 , the second housing 23 is formed into a flat shape in the width direction as a whole. The second housing 23 is arranged above the first housing 22 in the inner housing 10 .

[0054] The second housing 23 has a plurality of second cavities 39 therein. Each second cavity 39 is provided through the second housing 23 in the front-back direction. Figure 1 As shown, the second housing 23 has a second lance 41 that protrudes forward from the inner wall of the second cavity 39. The terminal fitting 19 is inserted from the rear into the second cavity 39 of the second housing 23. The terminal fitting 19 is locked by the second lance 41 and prevented from being removed from the second cavity 39.

[0055] like Figure 9 As shown, the front portion of the lower wall of the second housing 23 is cut away. Each second lance 41 is exposed in the front portion of the lower wall of the second housing 23. The second housing 23 has a second slit 42 extending in the width direction between the front and rear portions. The second slit 42 communicates with each second cavity 39. The retaining portion 21 of the front member 11 is inserted into the second slit 42 from the side.

[0056] The lower surface of the second housing 23 is formed as a second facing surface 43 that is flat along the width direction. The second lances 41 are exposed at the front of the second facing surface 43. A second slit 42 is formed between the front and rear portions of the second facing surface 43.

[0057] like Figure 8 As shown, the second housing 23 has a side facing portion 44 located on one side in the width direction, and a side facing portion 45 located on the other side in the width direction and having a vertical dimension smaller than that of the side facing portion 44. A second step 46 in the height direction is formed between the side facing portion 44 and the side facing portion 45. Figure 4 As shown, the one-side opposing portion 44 is disposed in the inner housing 10 so as to oppose the low-height portion 28 from above. The other-side opposing portion 45 is disposed in the inner housing 10 so as to oppose the high-height portion 29 from above. The one-side opposing portion 44 has a width dimension corresponding to the low-height portion 28, and the other-side opposing portion 45 has a width dimension corresponding to the high-height portion 29. The second step 46 has a smaller height dimension than the first step 31.

[0058] like Figure 8 As shown, the second cavities 39 are arranged in multiple rows along the width direction in two layers, one above the other, on the one-side opposing portion 44. In the other-side opposing portion 45, multiple second cavities 39 are arranged in a row along the width direction. The second cavities 39 formed in the other-side opposing portion 45 have a larger diameter than the second cavities 39 formed in the one-side opposing portion 44.

[0059] like Figure 8 and Figure 9 As shown, a second locking portion 51 is protruding from the second opposing surface 43 at the rear of the one-side opposing portion 44. The second locking portion 51 includes a base portion 52 protruding from the second opposing surface 43 at three locations spaced apart in the width direction; a pair of pressed portions 53 spanning between adjacent base portions 52 in the width direction; and a locking plate 54 protruding in a cantilevered manner from the base portion 52 located on the other side in the width direction. The two pressed portions 53 and the locking plate 54 are arranged opposite to the second opposing surface 43 at the rear of the one-side opposing portion 44, spaced apart from each other. The locking plate 54 has a locking hole 55 with a rectangular opening in the center. The locking plate 54 can bend and deform up and down with the connection point with the base portion 52 located on the other side in the width direction as a fulcrum. The base portion 52 located on the center side in the width direction is formed into a rectangular frame shape.

[0060] Like the first housing 22, the second housing 23 has a plurality of protrusions 37 that protrude rearward from the rear surface and are positioned in the positioning holes 38 of the sealing member 12. The protrusions 37 are arranged side by side in the width direction on the upper portion of the rear surface of the second housing 23.

[0061] like Figure 8 As shown in FIG. 4 , the second facing surface 43 of the other side facing portion 45 is arranged at a position one level higher than the second facing surface 43 of the one side facing portion 44 via the second step 46 . Figure 9 As shown, the second facing surface 43 of the other-side facing portion 45 is formed flat as a whole and does not include any concavo-convex shapes.

[0062] <Structure and function of the inner shell>

[0063] During assembly, the second housing 23 is lowered from above onto the first housing 22. This positions the second facing surface 43 of the rear portion of the one-side facing portion 44 against the upper surfaces of the two guide ribs 33 and the upper surface of the closing portion 36, the lower surface of the second locking portion 51 against the first facing surface 27 of the rear portion of the low-height portion 28, and the second facing surface 43 of the other-side facing portion 45 against the first facing surface 27 of the high-height portion 29. At this point, the locking tab 54 abuts one side in the width direction relative to the locking protrusion 35, and the second housing 23 is displaced from its normal assembly position toward one side in the width direction relative to the first housing 22.

[0064] Then, the second shell 23 slides relative to the first shell 22 to the other side in the width direction. During the movement of the second shell 23, the second opposing surface 43 of the rear portion of the opposing portion 44 on one side slides on the upper surfaces of the two guide ribs 33, the lower surface of the second locking portion 51 slides on the first opposing surface 27 of the rear portion of the low-height portion 28, and the second opposing surface 43 of the opposing portion 45 on the other side slides on the first opposing surface 27 of the high-height portion 29. In addition, during the movement of the second shell 23, the front and rear ends of each pressed portion 53 drill into the bottom of each pressing portion 34, and further, the locking plate 54 interferes with the locking protrusion 35 and is bent and deformed upward. Then, the locking plate 54 elastically recovers, as shown in FIG. Figure 2 As shown, the locking protrusion 35 engages with the locking hole 55 of the locking plate 54. Furthermore, the second step 46 of the second housing 23 comes into contact with the first step 31 of the first housing 22, stopping the movement of the second housing 23. The locking plate 54 locks the locking protrusion 35, thereby preventing the second housing 23 from shifting in the width direction relative to the first housing 22. Furthermore, the front and rear ends of each pressed portion 53 contact the lower surface of each pressing portion 34, thereby preventing the second housing 23 from shifting away from the first housing 22.

[0065] Through the above, the second shell 23 is properly assembled to the first shell 22, as shown in FIG. Figure 3 As shown in FIG, the inner housing 10 is formed by maintaining the first housing 22 and the second housing 23 in a combined state. Figure 5 As shown, when viewing the inner housing 10 from the rear, on the other side in the width direction, the second opposing surface 43 of the other-side opposing portion 45 contacts the first opposing surface 27 of the high portion 29, the first step 31 and the second step 46 contact each other in the width direction, and on one side in the width direction, the second opposing surface 43 of the rear portion of the one-side opposing portion 44 contacts the upper surface of the rear guide rib 33. Therefore, on the rear surface of the inner housing 10, the boundary between the first shell 22 and the second shell 23 is in contact without a gap.

[0066] On the other hand, Figure 4 As shown, when the inner housing 10 is viewed from the front, the second opposing surface 43 of the other-side opposing portion 45 contacts the first opposing surface 27 of the high-height portion 29 on the other side in the width direction. However, on one side in the width direction, a gap is formed in the vertical direction between the first opposing surface 27 of the front portion of the low-height portion 28 and the second opposing surface 43 of the front portion of the one-side opposing portion 44. The first opposing surface 27 of the front portion of the low-height portion 28 and the second opposing surface 43 of the front portion of the one-side opposing portion 44 are arranged to face each other in parallel with the gap.

[0067] Here, a recess 56 is formed on one side in the width direction of the front surface of the inner housing 10, opening between the first opposing surface 27 and the second opposing surface 43. The inner bottom surface of the recess 56 is defined by the guide rib 33 on the front side of the first locking portion 32. One end of the recess 56 in the width direction is open to one side surface of the inner housing 10. The other end of the recess 56 in the width direction is defined by the first step 31. The upper surface of the recess 56 is defined by the second opposing surface 43 in the front portion of the one-side opposing portion 44. The lower surface of the recess 56 is defined by the first opposing surface 27 in the front portion of the low-height portion 28. Obviously, the recess 56 is formed in the shape of a slit groove that is long in the width direction.

[0068] When the connector is mated with the mating housing 90, the jam-prevention projection 92 is positioned so as to enter the recess 56 through the hole in the front member 11. Thus, the upper surface of the projection 92 faces and contacts the second facing surface 43 of the front portion of the one-side facing portion 44. The lower surface of the projection 92 faces and contacts the first facing surface 27 of the front portion of the low-profile portion 28. The recess 56 is thus filled with the projection 92.

[0069] Thus, according to this embodiment, the first locking portion 32 and the second locking portion 51 are located behind the first opposing surface 27 and the second opposing surface 43, respectively. The first and second housings 22 and 23 have recesses 56 that receive the protrusions 92 of the mating housing 90 in the inner housing 10 when the housing 10 is in the combined state. The recesses 56 are located between the front portions of the first opposing surface 27 and the front portions of the second opposing surface 43, and forward of the engaging portions of the first and second locking portions 32 and 51. Therefore, the recesses 56 formed forward of the engaging portions of the first and second locking portions 32 and 51 can serve as a portion for receiving the protrusions 92. Consequently, the space between the first opposing surface 27 of the first housing 22 and the second opposing surface 43 of the second housing 23 is effectively utilized.

[0070] In the present embodiment, the protrusion 92 for preventing jamming is arranged along the surface direction, more specifically, the width direction, of the first facing surface 27 and the second facing surface 43 , and can accommodate an increase in the width direction of the protrusion 92 .

[0071] Furthermore, the first shell 22 and the second shell 23 have a plurality of protrusions 37, each protrusion 37 is arranged in each positioning hole 38 of the sealing member 12, and the root of the locking portion connecting the protrusion 37A in each protrusion 37 is arranged at a position connected to the first locking portion 32. Therefore, in addition to improving the space efficiency, the strength of the first locking portion 32 and the protrusion 37 can also be improved.

[0072] [Other embodiments of the present disclosure]

[0073] The embodiments disclosed this time should be considered in all respects as illustrative and non-restrictive.

[0074] In the above embodiment, the first and second locking portions are slide locks. However, as another embodiment, the first and second locking portions may be elastic locks having a locking mechanism that is elastic in the direction of separation of the first and second housings.

[0075] In the above-mentioned embodiment, the first locking portion is arranged at a position connected to the root of the locking portion connecting tab, but as another embodiment, the second locking portion may also be arranged at a position connected to the root of the locking portion connecting tab, or the first locking portion and the second locking portion may also be arranged at a position connected to the root of the locking portion connecting tab.

[0076] When the connector is in use, the front-to-back direction can be inclined relative to the horizontal direction or parallel to the vertical direction. In addition, the up-down direction can be inclined relative to the vertical direction or parallel to the horizontal direction.
