[4] The first locking portion is a hole or a recess, and the second locking portion is a protrusion inserted into the first locking portion.
[0013] According to this configuration, the movement of the terminal can be appropriately restricted by the engagement between the first locking portion provided on the metal portion of the terminal and the second locking portion which is the protrusion of the holding member. [5] The second connection portion is rod-shaped, the terminal has a protruding wall protruding in a direction intersecting the longitudinal direction of the second connection portion, and the first engagement portion is a hole penetrating the protruding wall.
[0014] According to this configuration, the movement of the terminal can be appropriately restricted by the engagement between the first locking portion, which is a hole provided in the protruding wall of the terminal, and the second locking portion, which is a convex portion of the holding member.
[0015] [6] The terminal has a resin portion that is integral with the metal portion, and the first locking portion is provided on the resin portion. According to this configuration, the first locking portion can be formed in the resin portion of the terminal.

Each first retainer side locking portion 55 includes a rear side locking portion 56 that locks with the first terminal side locking portion 35, and a front side locking portion 57 that locks with the first terminal side locking portion 35.
[0045] The rear side locking portion 56 can come into contact with a side surface on the rear side of the first terminal side locking portion 35. This allows the rear side locking portion 56 to restrict movement of the first terminal 22A toward the rear side of the retainer 27. The rear side locking portion 56 can bend in the radial direction of the first terminal holding portion 51. The front side locking portion 57 can come into contact with a side surface on the front side of the first terminal side locking portion 35. This allows the front side locking portion 57 to restrict movement of the first terminal 22A toward the front side of the retainer 27. The first terminal side locking portion 35 is sandwiched between the rear side locking portion 56 and the front side locking portion 57 in the length direction of the second connecting portion 34.
[0046] The first terminal holding portion 51 has a guide portion 58 on the rear side of the rear locking portion 56. The guide portion 58 is, for example, an inclined surface that is displaced toward the inner diameter side of the first terminal holding portion 51 toward the front side of the retainer 27. The guide portion 58 guides the first terminal side locking portion 35 to the rear side locking portion 56 when the first terminal 22A is inserted into the first terminal holding portion 51 from the insertion hole 53.
[0047] Before the retainer 27 is attached to the housing body 26, the first terminal 22A is assembled to the insertion hole 53 and the first terminal holding portion 51 from the rear side to the front side of the retainer 27. When the first terminal 22A is inserted into the first terminal holding portion 51, the first terminal side locking portion 35 comes into contact with the guide portion 58, so that the rear side locking portion 56 is bent radially outward.
[0048] As shown in Figs. 8 and 11, for example, a plurality of rear side locking portions 56 are provided. In this embodiment, three rear side locking portions 56 are provided.

In addition, the two elastic pieces 61 have, for example, the same shape as each other. The elastic piece 61 faces the protruding wall 47. In addition, the elastic piece 61 can bend in a direction approaching and moving away from the protruding wall 47.
[0051] 10, the second retainer side locking portion 62 is provided on the elastic piece 61. The second retainer side locking portion 62 is a convex portion protruding from the elastic piece 61. The second retainer side locking portion 62 is inserted into the second terminal side locking portion 45 which is a hole formed in the protruding wall 47. In other words, the second retainer side locking portion 62 is locked to the second terminal side locking portion 45. This allows the second retainer side locking portion 62 to restrict movement of the second terminal 22B to the front and rear sides of the retainer 27.
[0052] The elastic piece 61 has a guide portion 63 on the rear side of the second retainer side locking portion 62. The guide portion 63 is, for example, an inclined surface that is displaced toward the inner diameter side of the second terminal holding portion 52 toward the front side of the retainer 27. The guide portion 63 guides the second terminal side locking portion 45 to the second retainer side locking portion 62 when the second terminal 22B is inserted into the second terminal holding portion 52 from the insertion hole 53.
[0053] Before the retainer 27 is attached to the housing body 26, the second terminal 22B is assembled to the insertion hole 53 and the second terminal holding portion 52 from the rear side to the front side of the retainer 27. When the second terminal 22B is inserted into the second terminal holding portion 52, the second terminal side locking portion 45 comes into contact with the guide portion 63, so that the elastic piece 61 is deflected in a direction away from the protruding wall 47.
[0054] The housing body 26 has a fitting portion 26e into which the second terminal holding portion 52 is fitted. The fitting portion 26e is in contact with the back surface of each elastic piece 61. The back surface of the elastic piece 61 is the side surface opposite to the side of the elastic piece 61 facing the second terminal 22B. The fitting portion 26e restricts the movement of the elastic piece 61 in a direction away from the second terminal 22B. In other words, the fitting portion 26e maintains a state in which the second retainer side locking portion 62 is locked to the second terminal side locking portion 45.

[0061] The temperature sensor 24 may be, for example, an NTC thermistor, a PTC thermistor, or a PT sensor. The sensor body 24a is configured by housing, for example, a resin housing and a sensor element (not shown) connected to a lead wire 24b. The sensor body 24a is, for example, substantially rectangular. The sensor element outputs a signal according to a temperature change via the lead wire 24b. The lead wire 24b is electrically connected to a control unit (not shown) that controls charging of the battery 13 based on the signal from the sensor element.
[0062] (Configuration of holder 25) The holder 25 is attached to a retainer 27. The holder 25 holds the sensor body 24a in a state in which the sensor body 24a is in contact with the electric wire 23.
[0063] The holder 25 has an enclosing portion 71 that holds the sensor main body 24a. For example, a plurality of enclosing portions 71 are provided corresponding to the plurality of first terminals 22A, respectively. That is, there are two enclosing portions 71 in this embodiment. The holder 25 also has, for example, a connecting portion 72 that connects the plurality of enclosing portions 71 to each other. The holder 25 is, for example, an injection-molded product made of synthetic resin.
[0064] 7, the surrounding portion 71 collectively covers the electric wire 23 and the sensor main body 24a in contact with the surface of the electric wire 23. The surrounding portion 71 is inserted into the insertion hole 53 connected to the first terminal holding portion 51. A circumferential portion of the surrounding portion 71 is interposed between the inner circumferential surface of the insertion hole 53 and the sensor main body 24a. In addition, a circumferential portion of the surrounding portion 71 is interposed between the inner circumferential surface of the insertion hole 53 and the electric wire 23. In addition, the surrounding portion 71 is provided away from the first seal member 64a in the length direction of the electric wire 23.
[0065] 13 and 14, the surrounding portion 71 has a first divided body 73 and a second divided body 74. The first divided body 73 and the second divided body 74 sandwich the electric wire 23 and the sensor main body 24a in the direction in which the electric wire 23 and the sensor main body 24a overlap each other.
[0066] The first divided body 73 has a locking portion 75. Each of the multiple first divided bodies 73 has, for example, a pair of locking portions 75. The second divided body 74 has a locking portion 76. Each of the multiple second divided bodies 74 has, for example, a pair of locking portions 76. The first divided body 73 and the second divided body 74 are assembled to each other by the locking portion 75 engaging with the locking portion 76. In addition, when the first divided body 73 and the second divided body 74 are assembled to each other, the first divided body 73 and the second divided body 74 collectively cover the electric wire 23 and the sensor main body 24a.
[0067] 14 and 15, the surrounding portion 71 is configured to be able to change the distance between the first division 73 and the second division 74 when not inserted into the insertion hole 53. Specifically, when the first division 73 and the second division 74 are in contact with each other, a gap S is set between the locking portion 75 and the locking portion 76. The distance between the first division 73 and the second division 74 can be changed by the dimension of the gap S.
[0068] The surrounding portion 71 has, for example, a sensor holding portion 81 that holds the sensor main body 24a. The sensor holding portion 81 is formed, for example, on the first divided body 73. The sensor holding portion 81 holds the sensor main body 24a assembled to the first divided body 73 when the first divided body 73 is not assembled to the second divided body 74. The sensor holding portion 81 has, for example, a pair of claw portions 82 that can support the lower surface of the sensor main body 24a. When the first divided body 73 is not assembled to the second divided body 74, each claw portion 82 prevents the sensor main body 24a from falling off from the first divided body 73. As shown in FIG. 15 and FIG. 16, the second divided body 74 has, for example, a pressure-contact protrusion 74a. The pressure-contact protrusion 74a is provided at a position facing the sensor holding portion 81 of the first divided body 73. The pressure-contact protrusion 74a is pressure-contacted to the insulating coating 23b of the electric wire 23.
[0069] As shown in Fig. 16, the connecting portion 72 has a first split connecting portion 83 and a second split connecting portion 84. The first split connecting portion 83 connects a pair of first split bodies 73 to each other. Each of the first split bodies 73 and the first split connecting portion 83 are formed, for example, from a single part. The second split connecting portion 84 connects a pair of second split bodies 74 to each other. Each of the second split bodies 74 and the second split connecting portion 84 are formed, for example, from a single part.
[0070] The first split connecting portion 83 has a positioning protrusion 83a. The positioning protrusion 83a fits into a positioning recess 84a of the second split connecting portion 84. The second split connecting portion 84 has a positioning protrusion 84b. The positioning protrusion 84b fits into a positioning recess 83b of the first split connecting portion 83.
[0071] As shown in Fig. 13, the first split connecting portion 83 has a first electric wire holding portion 83c. The second split connecting portion 84 has a second electric wire holding portion 84c. The first electric wire holding portion 83c and the second electric wire holding portion 84c face each other. As shown in Fig. 6, the first electric wire holding portion 83c and the second electric wire holding portion 84c surround the outer periphery of the electric wire 23 connected to the third terminal 22C. As a result, the first electric wire holding portion 83c and the second electric wire holding portion 84c hold the electric wire 23 connected to the third terminal 22C.
[0072] As shown in FIG. 7, the surrounding portion 71 is inserted into the insertion hole 53. The surrounding portion 71 has a holder side locking portion 85. The holder side locking portion 85 is, for example, a convex portion protruding from the outer circumferential surface of the surrounding portion 71. The holder side locking portion 85 is, for example, provided on each of the first division body 73 and the second division body 74. Meanwhile, the insertion hole 53 has a locked portion 53a. A plurality of the locked portions 53a are provided corresponding to the holder side locking portions 85 of the first division body 73 and the holder side locking portions 85 of the second division body 74. The locked portion 53a is, for example, a recess into which the holder side locking portion 85, which is a convex portion, is inserted. Each holder side locking portion 85 can be locked to each locked portion 53a in the direction in which the surrounding portion 71 is removed from the insertion hole 53.
[0073] The manner in which the connector 20 of this embodiment is assembled and its function will now be described. First, the electric wire 23 is connected to the terminal group 22 including the first terminal 22A, the second terminal 22B, and the third terminal 22C. At this time, the first seal members 64a and 64b are attached to the electric wire 23. In the first terminal 22A, the end of the core wire 23a of the electric wire 23 is crimped to the first connection portion 33, for example. In addition, the first connection portion 33 is subjected to, for example, watertightness between the electric wire 23 by the second seal member 65a. In addition, the first seal member 64a is fixed to the electric wire 23 by crimping the fixing portion 36. In the second terminal 22B, the end of the core wire 23a of the electric wire 23 is crimped to the first connection portion 43, for example. In addition, the first connection portion 43 is subjected to, for example, watertightness between the electric wire 23 by the second seal member 65b. In addition, the first seal member 64b is fixed to the electric wire 23 by crimping the fixing portion 46.
[0074] Next, the first terminal 22A, the second terminal 22B, and the third terminal 22C are assembled to the retainer 27. At this time, the first terminal 22A and the second terminal 22B are each inserted into the insertion hole 53 from the rear side to the front side of the retainer 27. As a result, the first terminal 22A is attached to the first terminal holding portion 51, and the second terminal 22B is attached to the second terminal holding portion 52.
[0075] Next, the holder 25 and the temperature sensor 24 are attached to the electric wire 23. Here, first, the sensor body 24a is attached to the sensor holding portion 81 of the first divided body 73. Next, the first divided body 73 and the second divided body 74 are attached to each other while sandwiching the electric wire 23 connected to the first terminal 22A. In this state, the distance between the first divided body 73 and the second divided body 74 is changeable.
[0076] Next, the holder 25 and the temperature sensor 24 attached to the electric wire 23 are assembled to the retainer 27. At this time, the surrounding portion 71 and the sensor body 24a held inside the surrounding portion 71 are moved toward the insertion hole 53 along the electric wire 23. Here, by leaving a margin in the distance between the first divided body 73 and the second divided body 74, the surrounding portion 71 and the sensor body 24a can be easily moved. In addition, at this time, since the holder 25 and the temperature sensor 24 are moved together, it is possible to prevent the lead wire 24b from being caught between the holder 25 and the electric wire 23. Then, the surrounding portion 71 is inserted into the insertion hole 53, and the holder side locking portion 85 of the surrounding portion 71 is locked to the locked portion 53a of the insertion hole 53. When the surrounding portion 71 is inserted into the insertion hole 53, the outer peripheral surface of the surrounding portion 71 and the inner peripheral surface of the insertion hole 53 are in contact with each other, so that the first divided body 73 and the second divided body 74 are in contact with each other. Then, the electric wire 23 and the sensor main body 24a are sandwiched between the first divided body 73 and the second divided body 74. As a result, the sensor main body 24a is pressed against the surface of the electric wire 23.
[0077] Next, the retainer 27 is assembled to the housing body 26. At this time, the first terminal holding portion 51 is fitted into the fitting portion 26d of the housing body 26, and the second terminal holding portion 52 is fitted into the fitting portion 26e of the housing body 26.
[0078] The effects of this embodiment will be described. (1) The terminal group 22 can be assembled into the insertion hole 53 from the rear side to the front side of the retainer 27. According to this configuration, after assembling each electric wire 23 to the terminal group 22, it is possible to assemble the terminal group 22 with the electric wires 23 to the retainer 27 from the rear side. Therefore, it is not necessary to perform the assembly work of the electric wires 23 and the terminal group 22 in a state where the electric wires 23 are passed through the retainer 27, and it is possible to improve the ease of assembly.
[0079] Further, the second retainer side locking portion 62 restricts movement of the second terminal 22B to the front and rear sides of the retainer 27 by engaging with the second terminal side locking portion 45. This allows the second terminal 22B to be stably held by the retainer 27 even before the retainer 27 is assembled to the housing body 26. Further, the first retainer side locking portion 55 restricts movement of the first terminal 22A to the front and rear sides of the retainer 27 by engaging with the first terminal side locking portion 35. This allows the first terminal 22A to be stably held by the retainer 27 even before the retainer 27 is assembled to the housing body 26.
[0080] (2) The second terminal 22B has a metal portion 41 formed by bending a metal plate. The first connection portion 43 and the second connection portion 44 are provided on the metal portion 41. The first terminal 22A has a metal portion 31 formed by bending a metal plate. The first connection portion 33 and the second connection portion 34 are provided on the metal portion 31. With this configuration, the first terminal 22A and the second terminal 22B can be formed by bending a metal plate.
[0081] (3) Second terminal side locking portion 45 is provided on metal portion 41 of second terminal 22B. According to this configuration, second terminal side locking portion 45 can be formed on metal portion 41 of second terminal 22B.
[0082] (4) Second terminal side locking portion 45 is a hole, and second retainer side locking portion 62 is a protrusion inserted into second terminal side locking portion 45. With this configuration, the second terminal side locking portion 45 provided on metal portion 41 of second terminal 22B engages with second retainer side locking portion 62 which is a protrusion of retainer 27, thereby making it possible to suitably restrict movement of second terminal 22B.
[0083] (5) Second terminal 22B has a protruding wall 47 that protrudes in a direction intersecting the longitudinal direction of second connection portion 44. Second terminal side locking portion 45 is a hole that penetrates protruding wall 47. With this configuration, second terminal side locking portion 45, which is a hole provided in protruding wall 47, engages with second retainer side locking portion 62, which is a convex portion of retainer 27, making it possible to appropriately restrict movement of second terminal 22B.
[0084] (6) First terminal 22A has resin portion 32 that is integral with metal portion 31. First terminal side locking portion 35 is provided on resin portion 32. According to this configuration, first terminal side locking portion 35 can be formed on resin portion 32 of first terminal 22A.
[0085] (7) When the second connection portion 34 side relative to the first connection portion 33 of the first terminal 22A is regarded as the tip side, the first seal member 64a is provided on the base end side of the first connection portion 33. The first terminal 22A has a fixing portion 36 that fixes the first seal member 64a to the outer circumferential surface of the electric wire 23. According to this configuration, the first seal member 64a is fixed to the first terminal 22A, so that the first seal member 64a can be positioned in the length direction of the electric wire 23. In addition, since the first seal member 64a is fixed to the outer circumferential surface of the electric wire 23 by the fixing portion 36 of the first terminal 22A, a separate member for pressing and fixing the first seal member 64a from the rear side is not required. As a result, it is possible to suppress an increase in the number of parts.
[0086] In addition, when the second connection portion 44 side relative to the first connection portion 43 in the second terminal 22B is defined as the tip side, the first seal member 64b is provided on the base end side relative to the first connection portion 43. The second terminal 22B has a fixing portion 46 that fixes the first seal member 64b to the outer circumferential surface of the electric wire 23. According to this configuration, the first seal member 64b is fixed to the second terminal 22B, so that the first seal member 64b can be positioned in the length direction of the electric wire 23. In addition, since the first seal member 64b is fixed to the outer circumferential surface of the electric wire 23 by the fixing portion 46 of the second terminal 22B, a separate member for pressing and fixing the first seal member 64b from the rear side is not required. As a result, it is possible to suppress an increase in the number of parts.
[0087] (8) The connector 20 includes a second seal member 65a that covers the portion of the electric wire 23 that is connected to the first connection portion 33 of the first terminal 22A. The connector 20 also includes a second seal member 65b that covers the portion of the electric wire 23 that is connected to the first connection portion 43 of the second terminal 22B. With this configuration, the second seal members 65a, 65b can prevent the first connection portions 33, 43 from being exposed to water. With this configuration, it is also not necessary to provide a rubber plug or the like on the front side of the first connection portions 33, 43, so that an increase in the number of parts can be prevented.
[0088] (9) Retainer 27 has guide portion 58 that guides first terminal side locking portion 35 to rear side locking portion 56 when first terminal 22A is inserted into insertion hole 53. Retainer 27 also has guide portion 63 that guides second terminal side locking portion 45 to second retainer side locking portion 62 when second terminal 22B is inserted into insertion hole 53. With this configuration, guide portions 58, 63 can improve the ease of assembly of first terminal 22A and second terminal 22B.
[0089] (10) The guide portions 58, 63 are inclined surfaces that are displaced toward the inner diameter side of the insertion hole 53 toward the front side of the retainer 27. According to this configuration, the guide portions 58, 63 are inclined surfaces, which makes it possible to more suitably improve the ease of assembly of the first terminal 22A and the second terminal 22B.
[0090] (11) The connector 20 includes a temperature sensor 24 and a holder 25. The temperature sensor 24 has a sensor body 24a attached to a surface of the electric wire 23, and a lead wire 24b extending from the sensor body 24a. The holder 25 has an enclosure 71 that collectively covers the electric wire 23 and the sensor body 24a. The housing 21 has an insertion hole 53 through which the electric wire 23 is inserted. The enclosure 71 is inserted into the insertion hole 53. The enclosure 71 is interposed between the inner circumferential surface of the insertion hole 53 and the electric wire 23, and between the inner circumferential surface of the insertion hole 53 and the sensor body 24a.
[0091] According to this configuration, if there is a design change in the diameter of the electric wire 23, this can be accommodated by changing the shape of the holder 25 side, such as by changing the radial thickness of the surrounding portion 71, while leaving the shape of the insertion hole 53 of the housing 21 unchanged. Therefore, even if there is a design change in the diameter of the electric wire 23, it becomes possible to eliminate the need to change the shape of the housing 21 side. Since the holder 25 can be configured to be smaller in size than the housing 21, it is possible to suppress an increase in cost by changing the molding die of the holder 25 compared to changing the molding die of the housing 21 side.
[0092] (12) The surrounding portion 71 is provided inside the insertion hole 53 so as to press the sensor body 24a against the surface of the electric wire 23. According to this configuration, the sensor body 24a is pressed against the surface of the electric wire 23 by the surrounding portion 71, so that a gap is unlikely to occur between the sensor body 24a and the surface of the electric wire 23. This makes it possible to improve the accuracy of the temperature detection of the electric wire 23 by the sensor body 24a.
[0093] (13) The surrounding portion 71 has a first divided body 73 and a second divided body 74. The first divided body 73 and the second divided body 74 sandwich the electric wire 23 and the sensor main body 24a in the direction in which the electric wire 23 and the sensor main body 24a overlap. According to this configuration, by sandwiching the electric wire 23 and the sensor main body 24a between the first divided body 73 and the second divided body 74, it is possible to press the sensor main body 24a against the surface of the electric wire 23.
[0094] (14) First division 73 has a locking portion 75. Second division 74 has a locking portion 76. Then, first division 73 and second division 74 are assembled to each other by locking portion 75 engaging with locking portion 76. According to this configuration, first division 73 and second division 74 can be assembled to each other by locking portion 75 and locking portion 76 with first division 73 and second division 74 collectively covering electric wire 23 and sensor main body 24a.
[0095] (15) The surrounding portion 71 is configured to be able to change the distance between the first divisional body 73 and the second divisional body 74 when not inserted into the insertion hole 53. With this configuration, before the surrounding portion 71 is assembled into the insertion hole 53, the distance between the first divisional body 73 and the second divisional body 74 can be made to have a margin with respect to the dimension obtained by adding up the diameter of the electric wire 23 and the thickness of the sensor main body 24a. This allows the first divisional body 73, the second divisional body 74, and the temperature sensor 24 assembled to the electric wire 23 to be easily moved in the length direction of the electric wire 23. In addition, when the surrounding portion 71 is assembled into the insertion hole 53, the first divisional body 73 and the second divisional body 74 can be brought close to each other to sandwich the electric wire 23 and the sensor main body 24a between them, and the sensor main body 24a can be pressed against the surface of the electric wire 23.
[0096] (16) The surrounding portion 71 has a sensor holding portion 81 that holds the sensor body 24a. The sensor holding portion 81 holds the sensor body 24a so that it does not come out of the surrounding portion 71 when the surrounding portion 71 is not inserted into the insertion hole 53. With this configuration, it is possible to assemble the holder 25 to the electric wire 23 with the sensor body 24a held by the sensor holding portion 81 of the surrounding portion 71. This makes it possible to improve the ease of assembling the temperature sensor 24 and the holder 25.
[0097] (17) The sensor holding portion 81 is formed on the first division 73. The sensor holding portion 81 holds the sensor main body 24a assembled to the first division 73 when the first division 73 is not assembled to the second division 74. According to this configuration, the first division 73 and the second division 74 can be assembled to the electric wire 23 with the sensor main body 24a held by the sensor holding portion 81 of the first division 73. This makes it possible to improve the ease of assembly of the temperature sensor 24, the first division 73, and the second division 74.
[0098] (18) A plurality of electric wires 23 are provided. A plurality of temperature sensors 24 are provided corresponding to the plurality of electric wires 23, respectively. A plurality of insertion holes 53 are provided corresponding to the plurality of electric wires 23, respectively. A plurality of surrounding portions 71 are provided corresponding to the plurality of electric wires 23 and the plurality of temperature sensors 24. The holder 25 has connecting portions 72 that connect the plurality of surrounding portions 71 to each other. According to this configuration, since the plurality of surrounding portions 71 are connected to each other by the connecting portions 72, it is possible to reduce the number of parts compared to the case where the plurality of surrounding portions 71 are each individual parts.
[0099] (19) The surrounding portion 71 has a holder-side locking portion 85. The insertion hole 53 has a locked portion 53a. The holder-side locking portion 85 can be locked to the locked portion 53a in the direction in which the surrounding portion 71 comes out of the insertion hole 53. With this configuration, the surrounding portion 71 can be prevented from coming out of the insertion hole 53 by locking the holder-side locking portion 85 with the locked portion 53a. In addition, since the surrounding portion 71 can be prevented from coming out by the holder-side locking portion 85 of the surrounding portion 71, it is not necessary to prevent the surrounding portion 71 from coming out by a locking member separate from the holder 25, and it is possible to prevent an increase in the number of parts.
[0100] (20) The first retainer locking portion 55 includes a rear locking portion 56 that restricts movement of the first terminal 22A toward the rear side of the retainer 27, and a front locking portion 57 that restricts movement of the first terminal 22A toward the front side of the retainer 27. According to this configuration, the rear locking portion 56 and the front locking portion 57 can restrict movement of the first terminal 22A toward the rear side and the front side of the retainer 27. This makes it possible to hold the first terminal 22A in the retainer 27 more stably.
[0101] (21) The first terminal side locking portion 35 is formed in a flange shape protruding from the first terminal 22A. The rear side locking portion 56 is capable of contacting a rear side surface of the first terminal side locking portion 35. The front side locking portion 57 is capable of contacting a front side surface of the first terminal side locking portion 35. With this configuration, the rear side locking portion 56 and the front side locking portion 57 are locked with the flange-shaped first terminal side locking portion 35, thereby making it possible to restrict movement of the first terminal 22A to the rear side and the front side of the retainer 27.
[0102] This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction. The number of the first terminals 22A and the number of the second terminals 22B are not limited to those in the above embodiment, and can be changed as appropriate depending on the configuration of the connector 20.
[0103] In the first terminal 22A and the second terminal 22B, the metal portions 31, 41 are formed by bending a metal plate, but the present invention is not limited to this. The metal portions 31, 41 may be formed by cutting.

The configuration of the first terminal side locking portion 35, such as its shape, is not limited to the above embodiment and can be modified as appropriate. For example, the first terminal side locking portion 35 is provided on the resin part 32, but is not limited thereto, and the first terminal side locking portion 35 may be provided on the metal part 31.
[0105] The configuration of the second terminal side locking portion 45, such as its shape, is not limited to the above embodiment and can be changed as appropriate. For example, in the above embodiment, the second terminal side locking portion 45 is a hole, and the second retainer side locking portion 62 is a protrusion inserted into the second terminal side locking portion 45, but the present invention is not limited to this, and the relationship of the protrusions and recesses between the second terminal side locking portion 45 and the second retainer side locking portion 62 may be reversed. In addition, the second terminal side locking portion 45 is not limited to a through hole, and may be a recess that does not penetrate. In addition, the protruding direction of the protruding wall 47 is not limited to a direction perpendicular to the length direction of the second connecting portion 44, and the protruding direction of the protruding wall 47 may be any direction that intersects with the length direction of the second connecting portion 44.
[0106] In the surrounding portion 71 of the above embodiment, the first division 73 and the second division 74 may be configured to be connected together, for example, via a hinge portion, and the first division 73 may be configured to be rotatable around the hinge portion.
[0107] In the above embodiment, the surrounding portion 71 is configured from two parts, the first divided body 73 and the second divided body 74. However, this is not limiting, and the surrounding portion 71 may be configured from a single part. The holder 25 in the above embodiment is configured to be able to hold the electric wire 23 connected to the third terminal 22C, but is not limited to this, and may be configured not to hold the electric wire 23.
