[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, [1] A housing and a retaining body mounted on the housing, the housing having a cylindrical peripheral wall, the peripheral wall having an installation opening for mounting the retaining body at an end portion in the axial direction of the peripheral wall, the retaining body being configured to be installed in or removed from the interior of the peripheral wall through the installation opening, the retaining body having a hooking portion, the hooking portion being capable of hooking a top end of a rod-shaped jig, the jig being used to remove the retaining body from the interior of the peripheral wall, the peripheral wall having a jig insertion hole penetrating the peripheral wall, and the connector being configured to hook the top end of the jig to the hooking portion through the jig insertion hole.

[0010] According to this structure, a rod-shaped jig can be inserted from the outer peripheral side of the peripheral wall into the inner part of the peripheral wall through the jig insertion hole, and the top end of the jig can be hooked on the hook portion of the retaining body. And, for example, by levering the jig with the peripheral edge of the jig insertion hole as a fulcrum, the retaining body can be pulled out from the inner part of the peripheral wall. According to the above structure, the position of the hook portion that can be set in the retaining body is not limited to the vicinity of the installation opening. As a result, the design freedom of the retaining body can be improved.

[0011] [2] Preferably, in the above [1], the peripheral wall has a reinforcing rib protruding from the peripheral edge of the jig insertion hole toward the outer peripheral side of the peripheral wall, and with respect to both ends of the jig insertion hole in the axial direction of the peripheral wall, when the side closer to the installation opening is taken as the first end and the side farther from the installation opening is taken as the second end, the reinforcing rib is provided on the peripheral edge of at least the second end of the jig insertion hole.

[0012] According to this structure, the rigidity of at least the second end portion of the jig insertion hole can be increased by the reinforcing rib, so that the lever operation of the jig using the second end portion of the jig insertion hole as a fulcrum can be stably performed.

[0013] [3] Preferably, in the above [1] or [2], with respect to the two ends of the jig insertion hole in the axial direction of the peripheral wall, when the side closer to the mounting opening is taken as the first end and the side farther from the mounting opening is taken as the second end, an inclined surface inclined toward the outer peripheral side of the peripheral wall is formed on the inner peripheral surface of the second end in the jig insertion hole.

[0014] According to this configuration, the operability when the jig is lever-operated using the second end portion in the jig insertion hole as a fulcrum can be improved, and as a result, the operability of removing the retainer can be improved.

[0015] [4] Preferably, in any one of the above [1] to [3], the shell has a terminal storage block on the inner side of the peripheral wall, the retaining body has an inner peripheral wall surrounding the terminal storage block on the inner side of the peripheral wall, the inner peripheral wall has the hook portion and the locking plate, the locking plate is locked to the terminal storage block in the axial direction of the peripheral wall, and the hook portion and the locking plate are arranged side by side in the axial direction of the peripheral wall.

[0016] According to this structure, a force for releasing the locking piece from the terminal receiving block can be generated by operating the lever of the jig when removing the retaining body. Therefore, the release property of the locking piece from the terminal receiving block can be improved. As a result, the workability of removing the retaining body can be improved.

[0017] [Details of Embodiments of the Invention] The following is a reference to the attached Figure 1 A specific example of the connector of the present invention is described. In each of the drawings, for the sake of convenience of explanation, a part of the structure is sometimes enlarged or simplified.

In addition, the "opposite" in this specification includes the situation where a component separated from the two parts is interposed between the two parts, and the situation where nothing is sandwiched between the two parts. In addition, the terms "first" and "second" in this specification are only used to distinguish objects, not to rank the objects. In addition, the present invention is not limited to these examples, but is shown by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0019] (Connector 10) Figure 1 The connector 10 shown is connected to an electrical device (not shown) mounted on a vehicle. The connector 10 includes a housing 11 and a retaining body 12 mounted on the housing 11. The housing 11 and the retaining body 12 are formed of, for example, a synthetic resin. The housing 11 is mated with a counterpart connector (not shown) provided on the electrical device in a first direction D1 along the X-axis. In the following description, the opposite direction to the first direction D1 along the X-axis is referred to as a second direction D2. The connector 10 includes, for example, a cover 13 and a rod 14, the cover 13 covers the end of the housing 11 in the second direction D2, and the rod 14 assists the housing 11 in mating with the counterpart connector. Figure 2 In the following drawings, illustration of the cover 13 and the rod 14 in the housing 11 is omitted.

[0020] (Housing 11) like Figure 2 and Figure 3 As shown, the housing 11 includes a cylindrical peripheral wall 21 and a terminal storage block 22 located inside the peripheral wall 21. The peripheral wall 21 is annular with the axis L1 of the peripheral wall 21 along the X axis as the center. When viewed from the second direction D2, the peripheral wall 21 is, for example, roughly square cylindrical. In addition, when viewed from the second direction D2, the terminal storage block 22 is, for example, roughly quadrilateral.

[0021] The peripheral wall 21 has an installation opening 23 at the end in the direction of the axis L1 of the peripheral wall 21. The installation opening 23 is provided at the end of the peripheral wall 21 in the first direction D1. In addition, in the following description, the first direction D1 is sometimes described as the front and the second direction D2 is sometimes described as the rear. That is, the installation opening 23 is provided at the front end of the peripheral wall 21. In addition, the installation opening 23 opens toward the front (the first direction D1). The other connector is fitted into the inner side of the peripheral wall 21 of the housing 11 through the installation opening 23.

[0022] like Figure 3 As shown, the terminal receiving block 22 has a plurality of terminal receiving holes 24 that penetrate the terminal receiving block 22 along the X-axis. The terminal T is received in each terminal receiving hole 24. The wire W connected to each terminal T is led out from the housing 11 in the second direction D2. A lance 25 that is engaged with the terminal T is provided inside each terminal receiving hole 24. When installing the terminal T, the terminal T is inserted into the terminal receiving hole 24 toward the first direction D1. At this time, the lance 25 elastically returns to its original position after being temporarily bent in the Z-axis direction due to contact with the terminal T, so that the lance 25 is engaged with the terminal T. Furthermore, since the terminal T is engaged with the lance 25, the terminal T does not slip out in the second direction D2.

[0023] (Jig insertion hole 32) like Figure 2 As shown, the peripheral wall 21 of the housing 11 includes a pair of side wall portions 31 that are opposed to each other in the Y-axis direction. Each side wall portion 31 forms a part of the peripheral wall 21. The terminal storage block 22 is located between the pair of side wall portions 31 in the Y-axis direction. The side wall portion 31 is provided with a jig insertion hole 32 that penetrates the side wall portion 31. The jig insertion hole 32 penetrates the side wall portion 31 in a direction orthogonal to the axis L1, for example. The jig insertion hole 32 penetrates the peripheral wall 21 in a manner that communicates with the space on the inner peripheral side and the space on the outer peripheral side of the peripheral wall 21.

[0024] like Figure 4 and Figure 5 As shown, the jig insertion hole 32 penetrates the side wall portion 31 in the Y-axis direction. The jig insertion holes 32 are, for example, respectively provided in a pair of side wall portions 31. In addition, the jig insertion holes 32 are, for example, respectively provided in two in each pair of side wall portions 31. Each jig insertion hole 32 has, for example, the same shape as each other.

[0025] When viewed from the Y-axis direction, the jig insertion hole 32 is, for example, roughly quadrilateral. More specifically, when viewed from the Y-axis direction, the jig insertion hole 32 is rectangular and extends along the X-axis. The jig insertion hole 32 has a first end 32a and a second end 32b as both ends in the axis L1 direction. At both ends of the jig insertion hole 32 in the axis L1 direction, the first end 32a is the end closer to the mounting opening 23, and the second end 32b is the end farther from the mounting opening 23.

[0026] like Figure 4 and Figure 5 As shown, the peripheral wall 21 of the housing 11 has a reinforcing rib 33 protruding from the peripheral edge of the jig insertion hole 32 to the outer peripheral side of the side wall portion 31. The reinforcing rib 33 is, for example, provided only on a portion of the peripheral edge of the jig insertion hole 32. Specifically, the reinforcing rib 33 is provided on the peripheral edge of the second end 32b of the jig insertion hole 32. The reinforcing rib 33 protrudes from the peripheral edge of the second end 32b of the jig insertion hole 32 in the Y-axis direction. The reinforcing rib 33 is, for example, formed over the entire area of ​​the second end 32b in the Z-axis direction. In addition, both ends of the reinforcing rib 33 in the Z-axis direction slightly extend in the first direction D1 along the peripheral edge of the jig insertion hole 32.

[0027] like Figure 5 As shown, an inclined surface 34 is formed on the inner peripheral surface of the second end 32b of the jig insertion hole 32, and the inclined surface 34 is inclined toward the rear side (the second direction D2 side) toward the outer peripheral side of the peripheral wall 21. The inclined surface 34 is formed, for example, from the middle part of the thickness of the side wall part 31 (the middle part in the Y-axis direction) to the top end of the reinforcing rib 33.

[0028] (Retaining body 12) like Figure 2 and Figure 3 As shown, the retaining body 12 is configured to be mounted and disassembled relative to the terminal receiving block 22 located inside the peripheral wall 21 through the installation opening 23. In addition, the retaining body 12 is assembled to the terminal receiving block 22 toward the second direction D2, and is disassembled from the terminal receiving block 22 toward the first direction D1. The retaining body 12 includes a front wall 41 and an inner peripheral wall 42 extending from the front wall 41. The front wall 41 is, for example, in the shape of a flat plate perpendicular to the X-axis. The front wall 41 covers the front of the terminal receiving block 22. The front wall 41 has through holes 43 at positions corresponding to the plurality of terminal receiving holes 24 in the terminal receiving block 22. Each through hole 43 penetrates the front wall 41 in the X-axis direction. The terminal of the other connector embedded in the inner side of the peripheral wall 21 of the housing 11 is inserted into the terminal receiving hole 24 through the through hole 43, and is connected to the terminal T in the terminal receiving hole 24.

[0029] like Figure 3As shown, the front wall 41 has a restriction portion 44 that restricts the bending of the lance 25. The restriction portion 44 is provided at a position corresponding to each of the plurality of lances 25. The restriction portion 44 restricts the bending of the lance 25 by being inserted into the back side of the lance 25. Thus, the terminal T can be prevented from coming out in the second direction D2.

[0030] The inner peripheral wall 42 of the holding body 12 is annular when viewed from the first direction D1 . The inner peripheral wall 42 is disposed inside the peripheral wall 21 of the housing 11 and surrounds the outer periphery of the terminal housing block 22 .

[0031] like Figure 2 and Figure 5 As shown, the inner peripheral wall 42 of the holding body 12 includes a pair of wall portions 45 that are opposed to each other in the Y-axis direction. Each wall portion 45 forms a part of the inner peripheral wall 42. The wall portion 45 is arranged between the terminal receiving block 22 and the side wall portion 31 in the Y-axis direction. That is, the wall portion 45 of the holding body 12 and the side wall portion 31 of the housing 11 are opposed to each other in the Y-axis direction.

[0032] (Hooking portion 51) like Figure 5 As shown, the wall portion 45 in the inner peripheral wall 42 of the retaining body 12 has a hook portion 51, and the hook portion 51 can hook the top end of a rod-shaped jig J, and the jig J is used to remove the retaining body 12 from the inside of the peripheral wall 21. The hook portion 51 is, for example, recessed on the outer side of the wall portion 45. The hook portion 51 is configured to hook the top end of the jig J from the rear side of the hook portion 51 toward the front side. As the jig J, it is not a special jig prepared according to the shape of the connector 10, and a general jig such as a flat-blade screwdriver can be used.

[0033] The number of hooking parts 51 provided on one wall part 45 corresponds to the number of jig insertion holes 32 provided on one side wall part 31. In addition, the hooking parts 51 are provided on a pair of wall parts 45, for example. The hooking parts 51 are provided on each of the pair of wall parts 45, for example. Each hooking part 51 has the same shape as each other (see Figure 2 ).

[0034] (Locking piece 52) like Figure 5 As shown, the wall portion 45 in the inner peripheral wall 42 of the retaining body 12 has a locking piece 52, and the locking piece 52 is locked to the terminal receiving block 22 in the axis L1 direction (X-axis direction) of the peripheral wall 21. The locking piece 52 is shaped to extend toward the first direction D1. The locking piece 52 is formed to be able to bend in the Y-axis direction. The locking piece 52 has a locking protrusion 53 protruding inward in the Y-axis direction. The locking protrusion 53 is locked to the locked portion 26 provided on the terminal receiving block 22 toward the first direction D1. As a result, the retaining body 12 is maintained in a formally fixed position relative to the housing 11. In addition, Figure 1 , Figure 3 , Figure 4 and Figure 5 The state where the holding body 12 is held in the final fixed position is shown.

[0035] The hook portion 51 and the locking piece 52 are arranged side by side in the direction of the axis L1 (X-axis direction) of the peripheral wall 21. The top end of the locking piece 52 faces the first direction D1, and the base end of the locking piece 52 is arranged in the X-axis direction with the hook portion 51. That is, the hook portion 51 is arranged behind the base end of the locking piece 52.

[0036] The number of the locking pieces 52 provided on one wall portion 45 corresponds to the number of the hooking portions 51 provided on one wall portion 45, and two are provided. In addition, the locking pieces 52 are provided on, for example, a pair of wall portions 45, respectively. The locking pieces 52 are provided on, for example, a pair of wall portions 45, respectively, two. That is, the retaining body 12 has a total of four locking pieces 52. Each locking piece 52 has, for example, the same shape as each other.

[0037] When the holding body 12 located in the formal fixed position is removed from the housing 11, the jig J is inserted into the interior of the peripheral wall 21 through the jig insertion hole 32 in the housing 11, and the tip of the jig J is hooked on the hook portion 51 in the holding body 12. The hook portion 51 of the holding body 12 and the jig insertion hole 32 of the housing 11 are arranged at the same position in the Z-axis direction. In addition, when the holding body 12 is located in the formal fixed position, the hook portion 51 is located on the rear side of the second end portion 32b of the jig insertion hole 32.

[0038] like Figure 2 As shown, the wall portion 45 in the inner peripheral wall 42 of the retaining body 12 has a temporary retaining stopper 54 that is locked to the terminal storage block 22 in the first direction D1. The temporary retaining stopper 54 is arranged, for example, in the Z-axis direction relative to the hook portion 51. For example, two temporary retaining stoppers 54 are provided on each of the pair of wall portions 45. That is, the retaining body 12 has a total of four temporary retaining stoppers 54. Each temporary retaining stopper 54 has, for example, the same shape as each other.

[0039] like Figure 6 As shown, the temporary holding stopper 54 is locked with the temporary holding stopper 27 provided on the terminal receiving block 22 in the first direction D1, thereby holding the holding body 12 at the temporary holding position relative to the housing 11. Figure 6In the figure, the retaining body 12 at the formal fixed position is indicated by a solid line, and the retaining body 12 at the temporary retaining position is indicated by a double-dashed line. When the retaining body 12 is retained at the temporary retaining position, the retaining body 12 is located in the front (first direction D1) side of the formal fixed position. When the retaining body 12 is retained at the temporary retaining position, the limiting portion 44 of the retaining body 12 is not inserted into the back side of the lance 25 in the terminal receiving block 22, thereby allowing the lance 25 to bend. Therefore, when the retaining body 12 is retained at the temporary retaining position, the terminal T can be mounted in the terminal receiving hole 24.

[0040] The operation of this embodiment will be described. When the retaining body 12 is mounted on the terminal receiving block 22 of the housing 11, the retaining body 12 is inserted toward the inner side of the peripheral wall 21 in the second direction D2. At this time, first, the retaining body 12 is retained at the temporary retaining position by causing the temporary retaining stopper 54 of the retaining body 12 to be locked to the terminal receiving block 22. Then, with the retaining body 12 located at the temporary retaining position, the terminal T is mounted to the terminal receiving hole 24 in the terminal receiving block 22. With the retaining body 12 located at the temporary retaining position, the lance 25 is allowed to be bent, so that the lance 25 can be locked to the terminal T by the bending of the lance 25.

[0041] After each terminal T is installed in each terminal receiving hole 24, the retaining body 12 located at the temporary holding position is pressed in the second direction D2. And, by making the locking piece 52 of the retaining body 12 locked to the locked portion 26 of the terminal receiving block 22, the retaining body 12 is retained in the formal fixed position. When the retaining body 12 is located in the formal fixed position, the limiting portion 44 of the retaining body 12 limits the bending of the lance 25. Thus, the terminal T can be limited from coming out in the second direction D2.

[0042] When removing the retaining body 12 from the housing 11, the retaining body 12 is pulled out in the first direction D1 using the jig J. At this time, the jig J is inserted from the outer peripheral side of the peripheral wall 21 into the inner part of the peripheral wall 21 through the jig insertion hole 32, and the top end of the jig J is hooked on the hook portion 51 of the retaining body 12. Figure 5 As shown by the solid arrow, the jig J is lever-operated with the second end portion 32 b of the jig insertion hole 32 as a fulcrum, so that a force toward the forward side is applied to the hook portion 51 .

[0043] Here, the force applied from the jig J to the hook portion 51 also includes a component toward the inner side in the Y-axis direction. When a force toward the inner side in the Y-axis direction is applied to the hook portion 51, a torsional force is generated that deforms the portion of the wall portion 45 that is closer to the front side than the hook portion 51 toward the outer side in the Y-axis direction. That is, a force F is generated that displaces the locking piece 52 toward the outer side in the Y-axis direction. This force F is a force in the direction of releasing the locking of the locking piece 52 from the locked portion 26. Therefore, while a force toward the forward side is applied to the hook portion 51 by the lever operation of the jig J, the locking of the locking piece 52 is easily released by the force F.

[0044] By operating the lever of the jig J, a force is applied to the retaining body 12 in the forward direction, thereby releasing the locking of the locking piece 52 relative to the locked portion 26, and the retaining body 12 moves to the position larger than the retaining body 12. Figure 5 The formal fixing position shown is towards the front. Figure 7 , for example, shows a state in which the retaining body 12 is moved from the formal fixed position to the temporary retaining position. In this state, the retaining body 12 is moved to the front side of the formal fixed position, so that the positional relationship between the hook portion 51 and the second end portion 32b of the jig insertion hole 32, which serves as the lever operation fulcrum of the jig J, changes, and the inclination of the jig J operated by the lever also changes. Here, since the inclined surface 34 formed on the inner peripheral surface of the second end portion 32b of the jig insertion hole 32 is inclined in the direction in which the jig J is inclined, the operability of removing the retaining body 12 by the lever operation of the jig J is improved. In addition, by releasing the locking of the temporary retaining locking portion 54 relative to the terminal storage block 22, the retaining body 12 can be removed in the first direction D1.

[0045] The effects of this embodiment will be described. (1) The peripheral wall 21 of the housing 11 has a jig insertion hole 32 that penetrates the peripheral wall 21. According to this structure, a rod-shaped jig J can be inserted from the outer peripheral side of the peripheral wall 21 into the inside of the peripheral wall 21 through the jig insertion hole 32, and the top end of the jig J can be hooked on the hook portion 51 of the retaining body 12. And, for example, by levering the jig J with the peripheral edge of the jig insertion hole 32 as a fulcrum, the retaining body 12 can be pulled out from the inside of the peripheral wall 21. According to the above structure, the position where the hook portion 51 can be set in the retaining body 12 is not limited to the vicinity of the mounting opening 23. As a result, the design freedom of the retaining body 12 can be improved.

[0046] (2) The peripheral wall 21 of the housing 11 has a reinforcing rib 33 protruding from the peripheral edge of the jig insertion hole 32 toward the outer peripheral side of the peripheral wall 21. With respect to both ends of the jig insertion hole 32 in the direction of the axis L1 of the peripheral wall 21, the side closer to the mounting opening 23 is referred to as the first end 32a, and the side farther from the mounting opening 23 is referred to as the second end 32b. Furthermore, the reinforcing rib 33 is provided on the peripheral edge of at least the second end 32b of the jig insertion hole 32. According to this structure, the rigidity of at least the second end 32b of the jig insertion hole 32 can be improved by using the reinforcing rib 33. Therefore, the lever operation of the jig J with the second end 32b of the jig insertion hole 32 as a fulcrum can be stably performed.

[0047] (3) An inclined surface 34 is formed on the inner peripheral surface of the second end 32b of the jig insertion hole 32, which is inclined toward the outer peripheral side of the peripheral wall 21. According to this structure, the operability of the jig J when the second end 32b of the jig insertion hole 32 is used as a fulcrum can be improved, and as a result, it can help improve the workability of removing the retaining body 12.

[0048] (4) The housing 11 includes a terminal receiving block 22 on the inner side of the peripheral wall 21. The retaining body 12 includes an inner peripheral wall 42 surrounding the terminal receiving block 22 on the inner side of the peripheral wall 21. The inner peripheral wall 42 includes a hook portion 51 and a locking piece 52, and the locking piece 52 is locked to the terminal receiving block 22 in the direction of the axis L1 of the peripheral wall 21. In addition, the hook portion 51 and the locking piece 52 are arranged side by side in the direction of the axis L1 of the peripheral wall 21. According to this structure, a force F for releasing the locking piece 52 from the terminal receiving block 22 can be generated by operating the lever of the jig J when removing the retaining body 12. Therefore, the release property of the locking piece 52 from the terminal receiving block 22 can be improved. As a result, it can further contribute to the improvement of the workability of removing the retaining body 12.

[0049] (Other embodiments) The above-mentioned embodiment can be implemented as the following modifications. The above-mentioned embodiment and the following modifications can be implemented in combination with each other within the range of no technical contradiction.

[0050] In the holding body 12 of the above embodiment, the hook portion 51 and the locking piece 52 may not be arranged side by side in the axis L1 direction (X-axis direction) of the peripheral wall 21 . In the housing 11 of the above embodiment, the inner peripheral surface of the jig insertion hole 32 may be configured such that the inclined surface 34 is omitted.
