AI Technical Summary
The rod is prone to bending due to manufacturing tolerances, which may cause the rod connector to accidentally fall off during transportation or use.
By setting an extended wall on the housing to abut against the legs, the deformation of the legs is limited, and an anti-disengagement protrusion is set between the rotating shaft and the shaft hole. Combined with guiding and fitting detection components, the rod is ensured to rotate stably during the fitting process.
This effectively prevents the rod from falling off unexpectedly, ensuring stable engagement and use of the connector and simplifying the assembly process.

[0036] [Summary of Implementation Methods]
[0037] (1) The rod connector disclosed in this specification includes a housing, a rod, and a cover. The housing includes: a terminal holding portion having a wire guide surface and a cavity opening in the wire guide surface; rod holding walls disposed on both sides of the terminal holding portion; and a rotating shaft protruding from the rod holding walls toward the terminal holding portion. The rod has legs disposed between each of the rod holding walls and the terminal holding portion, the legs having shaft holes for receiving the rotating shaft. The rod is rotatable from an initial engagement position to a completed engagement position. The cover is assembled to the housing and covers the wire guide surface. The cover has an extension wall portion extending along the terminal holding portion from a position adjacent to the wire guide surface. The extension wall portion has an outer surface that abuts against the legs and restricts the deformation of the legs.
[0038] According to the above structure, by extending the outer surface of the wall to abut against the leg, the deformation of the leg is limited, thereby preventing the rod from falling off in case of accidents such as during the transport or use of the rod connector or during engagement with the other connector.
[0039] (2) In the rod connector of (1) above, the extension wall may also have an inner surface arranged along the terminal holding portion.
[0040] With this structure, when the cover is assembled into the housing, the inner surface of the extended wall portion is extended along the terminal retaining portion, thereby guiding the assembly of the cover relative to the housing, so that the cover can be smoothly assembled into the housing.
[0041] (3) In the rod connector of (1) or (2) above, the housing may also have an anti-detachment protrusion, which is disposed adjacent to the protruding end of the rotating shaft. By protruding from the outer peripheral surface of the rotating shaft and locking with the periphery of the shaft hole in the leg, the rotating shaft is restricted from detaching from the shaft hole. The rod has a recess at the periphery of the shaft hole, which communicates with the shaft hole. The anti-detachment protrusion is allowed to pass only when the rod is in the assembly position between the initial engagement position and the completed engagement position.
[0042] In the above structure, the rod is allowed to be attached or detached when it is in the assembly position between the initial engagement position and the completed engagement position. In this case, it is possible for the rod to detach midway through rotation between the initial engagement position and the completed engagement position. In such a structure, when a structure utilizing an extended wall to limit the deformation of the legs is applied, accidental detachment of the rod during engagement with the other connector can be avoided, and therefore this is preferable.
[0043] (4) In the rod connector of (1), (2) or (3) above, the rod may have a guide portion and the cover may have a guide receiving portion. The guide receiving portion extends along the rotation trajectory of the guide portion when the rod rotates from the initial engagement position to the completed engagement position and abuts against the guide portion.
[0044] With this structure, the rod is guided by the guide portion and then smoothly rotates from the initial engagement position to the completed engagement position.
[0045] (5) In the rod connector described in (4) above, the rod may also have a rod body and a mating detection member. The mating detection member is assembled to the rod body in a manner that allows it to move between a standby position and a detection position. The guide portion is disposed on the mating detection member. When the rod is in a position other than the mating completion position, the guide receiving portion abuts against the guide portion to restrict the movement of the mating detection member from the standby position to the detection position. When the rod is in the mating completion position, it is disposed in a position that does not contact the guide portion.
[0046] With this structure, the structure can be simplified because the guide receiving part serves to both guide the rotation of the rod and restrict the movement of the fitting detection member from the standby position to the detection position when the rod is in a position other than the fitting completion position.
[0047] [Details of the implementation method]
[0048] The following is a reference to the appendix. Figure 1 Specific examples of the technology disclosed in this specification are illustrated below. Furthermore, the invention is not limited to these examples, but is intended to include all variations within the meaning and scope of the claims, as shown by the claims.
[0049] <Implementation Method>
[0050] While referring to Figures 1 to 24 The implementation method will be described below. In this embodiment, the rod-type connector 1 is a female-type connector that mates with the male-type female connector 100. For example... Figure 1 and Figure 2 As shown, the rod connector 1 includes: a housing 10 for holding a wire W with a terminal part connected to its end; a rod 50 assembled to the housing 10; and a cover 80, also assembled to the housing 10.
[0051] [Shell 10]
[0052] The casing 10 is made of synthetic resin, such as Figure 3 and Figure 4 As shown, it has an inner housing 20 for holding the wire W and an outer housing 30 for holding the inner housing 20.
[0053] like Figure 3 and Figure 4 As shown, the inner housing 20 has a first wire guide surface 20A and a plurality of cavities 21 having wire guide openings 21A on the first wire guide surface 20A. Each cavity 21 can accommodate terminal parts and the ends of wires W connected to the terminal parts. Figure 1 and Figure 4 As shown, the wire W extends from the wire outlet 21A to the outside of the inner housing 20. Furthermore, in Figure 1 and Figure 4 In the diagram, only a portion of the wire W extending from a portion of the wire outlet 21A is shown; the other wires are omitted.
[0054] like Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, the outer casing 30 includes an inner retaining portion 31, a first cover retaining wall 33, a second cover retaining wall 34, two rod retaining walls 37, and two rotating shafts 38. The inner retaining portion 31 is generally oriented in one direction ( Figure 5 A rectangular prism shape that is longer in the left-right direction, such as Figure 3 and Figure 4As shown, the device has a second wire guide surface 31A and an inner receiving portion 32 with an opening in the second wire guide surface 31A. An inner housing 20 is housed in the inner receiving portion 32. The first wire guide surface 20A of the inner housing 20 is flush with the second wire guide surface 31A. The inner holding portion 31 and the inner housing 20 constitute a terminal holding portion 11.
[0055] like Figure 4 As shown, the two cover retaining walls 33 and 34 are U-shaped and arranged facing each other. The first cover retaining wall 33 is connected to one end of the inner retaining part 31 at a position adjacent to the second wire guide surface 31A. The second cover retaining wall 34 is connected to the other end of the inner retaining part 31 at a position adjacent to the second wire guide surface 31A. Figure 4 As shown, the first cover retaining wall 33 has a portion that protrudes beyond the second wire guide surface 31A, such as... Figure 7 As shown, this part is equipped with two locking holes 35 for engaging with the cover 80. (As...) Figure 4 As shown, the second cover retaining wall 34 has a portion that protrudes beyond the second wire guide surface 31A, such as... Figure 4 and Figure 18 As shown, this part is provided with two locking recesses 36 for engaging with the cover 80.
[0056] like Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, the two rod retaining walls 37 are arranged facing each other on both sides of the terminal retaining portion 11 in a position perpendicular to the wire guide surfaces 20A and 31A. Each rod retaining wall 37 is connected at one end to the first cover retaining wall 33 and at the other end to the second cover retaining wall 34, and is arranged with space left relative to the terminal retaining portion 11.
[0057] like Figure 3 and Figure 6 As shown, the space defined by the terminal holding part 11, the two cover holding walls 33 and 34, and the two rod holding walls 37 forms a fitting space 41. The fitting space 41 has a fitting opening 41A on the side opposite to the wire guide surfaces 20A and 31A, into which the other connector 100 can enter. Additionally, as... Figure 3 , Figure 5 as well as Figure 6 As shown, a portion of the space defined by the two rod retaining walls 37 and the terminal retaining portion 11 becomes the rod storage portion 42. The rod storage portion 42 has openings on both the wire guide surfaces 20A and 31A and the opposite side, allowing a portion of the leg 52 of the rod 50 to enter.
[0058] like Figure 3 , Figure 5 as well as Figure 16As shown, each of the two rotating shafts 38 is a cylindrical shaft that supports the rod 50 in a rotatable manner, protruding from the rod retaining wall 37 toward the terminal retaining portion 11. Anti-detachment protrusions 39 for preventing the rod 50 from detaching protrude from each of the two rotating shafts 38. The anti-detachment protrusions 39 are disposed adjacent to the protruding ends of the rotating shafts 38.
[0059]
[50]
[0060] Rod 50 is a component used to assist in the engagement and disengagement of housing 10 and connector 100. Rod 50 is made of synthetic resin, such as... Figure 8 As shown, the device includes a rod body 51 and a mating detection component 71. The rod body 51 is rotatably assembled relative to the housing 10. The mating detection component 71 is assembled to the rod body 51 and is used to confirm that the mating between the housing 10 and the other connector 100 is complete.
[0061] like Figure 8 As shown, the rod body 51 has two legs 52 and a rotation operation part 61 that connects the ends of the two legs 52 to each other.
[0062] like Figure 8 As shown, each of the two legs 52 is a slender plate-like shape, as... Figure 3 As shown, the terminal holding portions 11 are arranged facing each other on both sides. Figure 3 As shown, the top ends of each of the two legs 52 are housed in the two rod housings 42, and are respectively positioned along the two rod retaining walls 37. Figure 8 , Figure 9 as well as Figure 11 As shown, each leg 52 has a shaft hole 53 for receiving the rotating shaft 38, a gear portion 55 disposed around the shaft hole 53, and a retaining hole 56 and a sliding groove 57 for retaining the fitting detection member 71.
[0063] like Figure 8 , Figure 9 as well as Figure 11 As shown, the shaft hole 53 is a circular hole located at the top end of the leg 52 on the side opposite to the rotating operating part 61. A through recess 54 (an example of a recess) is provided around the periphery of the shaft hole 53, communicating with the shaft hole 53 and allowing the anti-slip protrusion 39 to pass through. Figure 8 , Figure 10 as well as Figure 11 As shown, the gear portion 55 is disposed in the leg portion 52 on the inner surface opposite to the terminal holding portion 11, and has a first gear tooth 55A and a second gear tooth 55B extending radially from the shaft hole 53. The first gear tooth 55A and the second gear tooth 55B are arranged with a gap between them. Figure 8 and Figure 9As shown, the retaining hole 56 is an elongated through hole disposed in the leg 52 at a position closer to the rotating operating part 61 than the shaft hole 53. Figure 8 and Figure 11 As shown, the sliding groove 57 is a groove disposed in the inner surface of the leg 52 at a position adjacent to the rotation operation part 61 and extending to a position slightly closer to the top end than the retaining hole 56.
[0064] like Figure 10 and Figure 11 As shown, the rotation operation unit 61 includes a first bridging portion 62 and a second bridging portion 63 that connect the ends of the two legs 52 to each other, and a third bridging portion 64 that connects the first bridging portion 62 and the second bridging portion 63 at a midpoint between the two legs 52. The space defined by the three bridging portions 62, 63, and 64 becomes a detection component storage portion 65 for storing the fitting detection component 71. Figure 11 As shown, the second bridging portion 63 has two detection protrusions 66, which protrude into the detection member receiving portion 65 and engage with the two detection pieces 76 of the fitting detection member 71 described later.
[0065] like Figure 12 As shown, the fitting detection member 71 includes: two arms 72 arranged facing each other; a pressing operation part 73 connecting the ends of the two arms 72 to each other; a guide part 74 and a retaining protrusion 75 protruding from each of the two arms 72; and two detection pieces 76 protruding from the pressing operation part 73 and disposed between the two arms 72.
[0066] like Figure 8 , Figure 10 , Figure 11 as well as Figure 12 As shown, the guide portion 74 is located at the top end of the arm 72 near the side opposite to the pressing operation portion 73, and includes a guide body 74A and a contact portion 74B. The guide body 74A is an L-shaped protrusion protruding from the inner surface of each arm 72 opposite to the opposite arm 72. The contact portion 74B is a small protrusion protruding from the guide body 74A toward the top end of the arm 72. Figure 8 and Figure 12 As shown, the protrusion 75, positioned adjacent to the tip of the arm 72, is a protrusion that extends from the outer surface of the arm 72 on the side opposite to the inner surface. Figure 11 and Figure 12 As shown, the detection piece 76 has a plate-shaped detection piece body 76A extending from the pressing operation part 73, and a detection claw 76B protruding from the top of the detection piece body 76A and engaging with the detection protrusion 66.
[0067] like Figure 8 and Figure 11As shown, the pressing operation part 73 and a portion of the arm 72 are housed in the detection component housing part 65, and each of the two arms 72 is slidably housed in one of the two sliding grooves 57. Figure 8 and Figure 10 As shown, the guide portion 74 is disposed protruding from the inner surface of the leg portion 52. As... Figure 9 As shown, each of the two retaining protrusions 75 is housed within one of the two retaining holes 56, and by engaging with the hole walls of the retaining holes 56, the engaging detection member 71 is held in place on the rod body 51. The engaging detection member 71 can be in the standby position ( Figure 11 The position shown) and the detection position ( Figure 23 The position is shifted between the positions shown. In the standby position, a part of the pressing operation part 73 protrudes from the rotating operation part 61. In the detection position, the pressing operation part 73 is completely housed inside the detection component housing part 65 and does not protrude from the rotating operation part 61.
[0068] Rod 50 can rotate around the rotation axis 38 as the center of rotation in the initial engagement position. Figure 2 , Figure 20 The position shown) and the position where the fitting is completed ( Figure 22 The lever 50 rotates between the positions shown. When in the initial engagement position, the lever 50 is positioned near the first cover retaining wall 33 with an inclined posture relative to the housing 10. When in the completed engagement position, the lever 50 is positioned near the second cover retaining wall 34 with an inclined posture relative to the housing 10.
[0069] [Cover 80]
[0070] The cover 80 is assembled relative to the housing 10 to cover the first wire guide surface 20A and the second wire guide surface 31A, and is a component for protecting the wire W that exits from the wire guide port 21A. The cover 80 is made of synthetic resin, such as... Figure 13 and Figure 14 As shown, it has a main wall 81 and two side walls 82 extending from the main wall 81.
[0071] like Figure 13 and Figure 14 As shown, the main wall 81 is generally in the shape of a shallow U-shaped groove, starting from one end that is adjacent to the first cover retaining wall 33. Figure 13 (The left front end) extends while curving gently.
[0072] Two sidewalls 82 extend from the two side edges of the main wall 81 and are arranged opposite each other. Each sidewall 82 has a first sidewall 83, a second sidewall 84, and a step portion 85 connecting the first sidewall 83 and the second sidewall 84. The second sidewall 84 is arranged further outward than the first sidewall 83, that is, away from the sidewall 82 on the opposite side. The step portion 85 has a guide receiving portion 85A and a terminal portion 85B. The guide receiving portion 85A extends in the sidewall 82 from the end adjacent to the first cover retaining wall 33 toward the opposite end in a gently curving manner. The terminal portion 85B extends from the end of the guide receiving portion 85A closer to the other end in a manner away from the main wall 81.
[0073] A portion of the second sidewall 84 becomes the extended wall portion 84A. For example... Figure 3 As shown, the extended wall portion 84A extends from the position adjacent to the second wire guide surface 31A to the top end portion in the second side wall 84. Figure 3 The portion extending along the terminal holding portion 11 from the lower end of the second side wall 84. In other words, the extended wall portion 84A is the portion of the second side wall 84 that extends further along the terminal holding portion 11 from a length sufficient to cover the wire guide surfaces 20A and 31A. Figure 3 and Figure 14 As shown, the extended wall portion 84A has an inner surface 84B disposed along the terminal holding portion 11 and an outer surface 84C on the opposite side thereof.
[0074] The cover 80 has two locking protrusions 87 and two locking tabs 86. For example... Figure 13 and Figure 17 As shown, each locking protrusion 87 is a plate-like protrusion that protrudes from one end of the main wall 81 and is received by the locking holes 35 of the first cover retaining wall 33. Figure 13 and Figure 18 As shown, each locking piece 86 has a locking piece body 86A connected to each side wall 82, and a locking claw 86B protruding from the locking piece body 86A. The locking claw 86B is received by each locking recess 36 of the second cover retaining wall 34.
[0075] [Partner Connector 100]
[0076] like Figure 15 As shown, the counterpart connector 100 includes: a base plate portion 101; a cylindrical cover portion 102 extending from the base plate portion 101; and two gear receiving portions 103 disposed on the outer surface of the cover portion 102, corresponding to two gear portions 55 respectively provided on the two legs 52 of the rod 50. A counterpart terminal part is held in the counterpart connector 100, and the counterpart terminal part is connected to a terminal part held in the rod connector 1. Each gear receiving portion 103 has a gear protrusion 104 that protrudes from the outer surface of the cover portion 102 and meshes with the gear teeth 55A, 55B of the gear portion 55.
[0077] [Assembly of rod connector 1]
[0078] The following describes an example of the assembly steps for the rod-type connector 1 with the above-described structure. First, the terminal part connected to the end of the wire W is assembled to the inner housing 20. Next, the inner housing 20 is assembled to the inner retaining part 31. The wire W is led out from the wire outlet 21A of each cavity 21 to the outside (see reference). Figure 4 ).
[0079] Next, assemble rod 50 into housing 10. (As shown) Figure 16 As shown, with the rod 50 in an assembled position upright relative to the housing 10, the two legs 52 bend inward, and the tip of each leg 52 inserts into the interior of the rod storage portion 42. When the rod 50 is in the assembled position, as... Figure 16 As shown, the position of the through recess 54 arranged on the periphery of the shaft hole 53 matches the anti-detachment protrusion 39, thus allowing the anti-detachment protrusion 39 to pass through the through recess 54 and allowing the rotating shaft 38 to enter relative to the shaft hole 53. When the rotating shaft 38 is inserted into the shaft hole 53, each leg 52 elastically returns to its original position and is arranged along the retaining wall 37 of each rod.
[0080] Then, rod 50 rotates from the assembled position to the initial engagement position. A gap exists between the anti-disengagement protrusion 39 and the rod retaining wall 37, and the periphery of the shaft hole 53 in leg 52 enters the gap (see reference). Figure 3 When the rod 50 rotates to a position deviating from its assembled posture, the position of the recess 54 becomes mismatched with the anti-detachment protrusion 39. Therefore, the anti-detachment protrusion 39 engages with the periphery of the shaft hole 53, preventing the rod 50 from disengaging from the housing 10. In this way, the assembly of the rod 50 into the housing 10 is completed. The rod 50 is supported and can rotate from the initial engagement position to the completed engagement position.
[0081] Next, assemble the cover 80 onto the housing 10. First, as... Figure 17 As shown, the cover 80 is formed in an inclined position with one end of the locking protrusion 87 closer to the housing 10 than the other end, and one end is inserted into the inner side of the first cover retaining wall 33. The locking protrusion 87 is inserted into the locking hole 35, thereby locking the locking protrusion 87 with the first cover retaining wall 33.
[0082] Next, the cover 80 rotates around the locking protrusion 87 as the center of rotation, so that the other end approaches the housing 10. At this time, the inner surfaces 84B of the two extended wall portions 84A are arranged along the terminal retaining portion 11, thereby guiding the assembly of the cover 80 into the housing 10 (see reference). Figure 3 When the other end of the cover 80 reaches the second cover retaining wall 34, the two locking tabs 86 are each pressed inward by the second cover retaining wall 34. When the cover 80 is assembled in the correct position relative to the housing 10, as... Figure 18As shown, each of the two locking claws 86B is housed in one of the two locking recesses 36, and the two locking tabs 86 elastically return to their original position and engage with the retaining wall 34 of the second cover. Thus, the assembly of the rod connector 1 is complete.
[0083] [Mating of rod connector 1 and counterpart connector 100]
[0084] Next, an example of the steps for engaging the rod-type connector 1 with the opposite connector 100 described above will be given below. First, as... Figure 19 and Figure 20 As shown, with the lever 50 held in the initial engagement position, the housing 10 and the counterpart connector 100 are shallowly engaged, and the top end of the cover 102 enters the interior of the engagement space 41. With the lever 50 positioned in the initial engagement position, as... Figure 20 As shown, the side of the two gear teeth 55A and 55B of each gear part 55 that is closer to the mating opening 41A ( Figure 20 The second gear tooth 55B (below) is positioned in a posture extending toward the fitting opening 41A, and the gear protrusion 104 can enter between the two gear teeth 55A and 55B. In addition, the two contact portions 74B of the fitting detection member 71 are each disposed at one end of the step portion 85 on the side of the first cover retaining wall 33, and abut against the guide receiving portion 85A.
[0085] Next, the rod 50 rotates from the engagement start position toward the engagement completion position. At this time, the two contact portions 74B of the engagement detection member 71 slide against the two guide receiving portions 85A on one side, allowing the rod 50 to rotate smoothly. As the rod 50 rotates, the gear portion 55 rotates, and the second gear tooth 55B moves toward the inside of the housing 10. The gear receiving portion 103, which engages with the second gear tooth 55B, is pulled into the inside of the housing 10. Simultaneously, the housing 10 is pulled closer to the opposite connector 100 for engagement.
[0086] During its rotation from the initial engagement position to the completed engagement position, lever 50 passes through the assembly position where it assumes an assembly posture. Just as lever 50 reaches the assembly position, as... Figure 21 As shown, the position of the recess 54 matches the anti-detachment protrusion 39, thus allowing the anti-detachment protrusion 39 to pass through the recess 54. Simultaneously, the rotating shaft 38 is allowed to pass through the shaft hole 53. Therefore, if, due to reasons such as manufacturing tolerances, the leg 52 of the rod 50 is prone to bend inwards, i.e., towards the terminal holding portion 11, it is possible that when the rod 50 just reaches the assembly position, the rotating shaft 38 and the anti-detachment protrusion 39 pass through the shaft hole 53 and the recess 54, causing the rod 50 to detach from the housing 10.
[0087] In this embodiment, a portion of each of the two second sidewalls 84 of the cover 80 becomes an extended wall portion 84A disposed along the terminal retaining portion 11. For example... Figure 21 As shown, the outer surface 84C of each extended wall portion 84A is arranged along each leg portion 52, and abuts against the leg portion 52 when the leg portion 52 is about to bend inward, thereby inhibiting further bending of the leg portion 52. Thus, the rod 50 can be prevented from accidentally falling off.
[0088] When rod 5 reaches the engagement completion position, as Figure 22 As shown, the housing 10 reaches the proper engagement position relative to the counterpart connector 100. With the lever 50 in the engagement completed position, the two contact portions 74B of the engagement detection member 71 disengage from the guide receiving portion 85A. This allows the engagement detection member 71 to be pressed from the standby position into the detection position. Conversely, if the lever 50 has not reached the engagement completed position, the contact portions 74B abut against the guide receiving portion 85A, and therefore the engagement detection member 71 cannot be pressed into the detection position. Thus, based on whether the engagement detection member 71 can be pressed in, it can be determined whether the lever 50 has rotated to the engagement completed position and whether the lever connector 1 and the counterpart connector 100 have reached the proper engagement position.
[0089] After rod 50 is retracted into the fully engaged position, as Figure 23 and Figure 24 As shown, the fitting detection component 71 is pressed from the standby position into the detection position. Figure 23 As shown, the detection claw 76B crosses the detection protrusion 66, causing the detection piece 76 to flex. When the detection claw 76B crosses the detection protrusion 66, the detection piece 76 elastically returns to its original position, and the detection claw 76B engages with the detection protrusion 66. Thus, the engaging detection member 71 is locked in the detection position. In the state where the engaging detection member 71 is locked in the detection position, as... Figure 24 As shown, the guide portion 74 abuts against the terminal portion 85B, thereby restricting the rotation of the rod 50 towards the initial engagement position, and locking the rod 50 in the completed engagement position. In this way, the engagement of the rod connector 1 and the counterpart connector 100 is completed.
[0090] [Effects]
[0091] As described above, according to this embodiment, the rod connector 1 includes a housing 10, a rod 50, and a cover 80. The housing 10 includes: a terminal holding portion 11 having wire guide surfaces 20A and 31A and a cavity 21 opening in the wire guide surfaces 20A and 31A; rod holding walls 37 disposed on both sides of the terminal holding portion 11; and a rotation shaft 38 protruding from the rod holding walls 37 toward the terminal holding portion 11. The rod 50 has legs 52 disposed between each of the rod holding walls 37 and the terminal holding portion 11, and has shaft holes 53 for receiving the rotation shaft 38. The rod 50 can rotate from an initial engagement position to a completed engagement position. The cover 80 is assembled to the housing 10 and covers the wire guide surfaces 20A and 31A. The cover 80 has an extension wall portion 84A extending along the terminal holding portion 11 from a position adjacent to the wire guide surfaces 20A and 31A. The extension wall portion 84A has an outer surface 84C that abuts against the legs 52 and restricts the deformation of the legs 52.
[0092] According to the above structure, by extending the outer surface 84C of the wall portion 84A to abut against the leg portion 52, the deformation of the leg 52 is limited, thereby preventing the rod 50 from falling off in case of accidents such as during the transport or use of the rod connector 1 or during engagement with the other connector 100.
[0093] In addition, the extension wall portion 84A has an inner surface 84B disposed along the terminal holding portion 11. With this structure, when the cover 80 is assembled to the housing 10, the inner surface 84B of the extension wall portion 84A along the terminal holding portion 11 can guide the assembly of the cover 80 relative to the housing 10, so that the cover 80 can be smoothly assembled to the housing 10.
[0094] Additionally, the housing 10 has an anti-detachment protrusion 39, which is disposed adjacent to the protruding end of the rotating shaft 38. By protruding from the outer peripheral surface of the rotating shaft 38 and locking with the periphery of the shaft hole 53 in the leg 52, the rotating shaft 38 is restricted from detaching from the shaft hole 53. The rod 50 has a through recess 54 at the periphery of the shaft hole 53, which communicates with the shaft hole 53. The anti-detachment protrusion 39 is allowed to pass through only when the rod 50 is in the assembly position between the initial engagement position and the completed engagement position.
[0095] In the above structure, the rod 50 is allowed to be attached and detached when it is in the assembly position between the initial engagement position and the completed engagement position. In this case, it is possible for the rod 50 to fall off during rotation between the initial engagement position and the completed engagement position. In such a structure, when a structure that uses the extended wall portion 84A to limit the deformation of the leg portion 52 is applied, accidental detachment of the rod 50 during engagement with the other connector 100 can be prevented.
[0096] In addition, the rod 50 has a guide receiving portion 85A, and the cover 80 has a guide portion 74. The guide portion 74 extends along the rotation trajectory of the guide receiving portion 85A when the rod 50 rotates from the initial engagement position to the completed engagement position, and abuts against the guide receiving portion 85A.
[0097] With this structure, the rod 50 can be smoothly rotated from the initial engagement position to the completed engagement position by being guided by the guide portion 74 and the guide receiving portion 85A.
[0098] In addition, the rod 50 includes a rod body 51 and a fitting detection member 71. The fitting detection member 71 is assembled to the rod body 51 in a manner that allows it to move between a standby position and a detection position. A guide portion 74 is provided on the fitting detection member 71. When the rod 50 is in a position other than the fitting completed position, the guide receiving portion 85A abuts against the guide portion 74 to restrict the movement of the fitting detection member 71 from the standby position to the detection position. When the rod 50 is in the fitting completed position, it is positioned in a position that does not contact the guide portion 74.
[0099] With this structure, the guide receiving part 85A serves to guide the rotation of the rod 50 and restrict the movement of the fitting detection member 71 from the standby position to the detection position when the rod 50 is in a position other than the fitting completion position, thus simplifying the structure.
