[Description of the embodiments of the present disclosure]
First, the embodiments of the present disclosure will be listed and described.
The connector of the present disclosure comprises:
[1] A sensor comprising a housing, a terminal accommodated in the housing, an electric wire electrically connected to the terminal, a temperature sensor having a sensor body attached to a surface of the electric wire and lead wires extending from the sensor body, and a holder having an enclosing portion that collectively covers the electric wire and the sensor body, wherein the housing has an insertion hole through which the electric wire is inserted, the enclosing portion is inserted into the insertion hole, and the enclosing portion is interposed between an inner surface of the insertion hole and the electric wire, and between the inner surface of the insertion hole and the sensor body.

With this configuration, if there is a design change in the wire diameter, it can be accommodated by changing the shape of the holder, such as changing the radial thickness of the enclosing part, while leaving the shape of the insertion hole of the housing unchanged. Therefore, even if there is a design change in the wire diameter, it becomes unnecessary to change the shape of the housing. Furthermore, since the holder can be configured to be smaller in size than the housing, it is possible to suppress cost increases by changing the mold for the holder compared to changing the mold for the housing.

[2] The surrounding portion is provided inside the insertion hole so as to press the sensor body against the surface of the electric wire.
According to this configuration, the sensor body is pressed against the surface of the electric wire by the surrounding portion, so that a gap is unlikely to occur between the sensor body and the surface of the electric wire, thereby improving the accuracy of the temperature detection of the electric wire by the sensor body.

[3] The enclosure has a first divided body and a second divided body, and the first divided body and the second divided body sandwich the electric wire and the sensor body in the direction in which the electric wire and the sensor body overlap. With this configuration, the electric wire and the sensor body are sandwiched between the first divided body and the second divided body, so that the sensor body can be pressed against the surface of the electric wire.

[4] The first division has a first locking portion, and the second division has a second locking portion, and the first locking portion locks into the second locking portion, thereby assembling the first division and the second division together.

With this configuration, the first and second divisions can be assembled together using the first and second locking parts while covering the electric wire and the sensor body together.

[5] The surrounding portion is configured to be able to change the distance between the first division and the second division when not inserted into the insertion hole.
According to this configuration, before the surrounding portion is assembled into the insertion hole, the distance between the first and second divisions can be set to have a margin with respect to the sum of the electric wire diameter and the thickness of the sensor body. This makes it possible to easily move the first and second divisions and the temperature sensor assembled to the electric wire in the length direction of the electric wire. Furthermore, when the surrounding portion is assembled into the insertion hole, the first and second divisions can be brought close to each other to sandwich the electric wire and the sensor body between the first and second divisions, and the sensor body can be pressed against the surface of the electric wire.

[6] The enclosure has a holding portion that holds the sensor body, and the holding portion holds the sensor body so that it does not come out of the enclosure when the enclosure is not inserted into the insertion hole.

With this configuration, it is possible to assemble the holder to the electric wire while the sensor body is held in the holding portion of the enclosure. This makes it possible to improve the ease of assembly of the temperature sensor and the holder.

[7] The surrounding portion has a first divided body and a second divided body, and the first divided body and the second divided body sandwich the electric wire and the sensor body in the direction in which the electric wire and the sensor body overlap, and the first divided body has the holding portion, and the holding portion holds the sensor body assembled to the first divided body when the first divided body is not assembled to the second divided body.

With this configuration, it is possible to assemble the first and second divisions to the electric wires while the sensor body is held by the holding portion of the first division. This makes it possible to improve the ease of assembly of the temperature sensor, the first and second divisions.

[8] A plurality of the electric wires are provided, a plurality of the temperature sensors are provided corresponding to the plurality of electric wires, a plurality of the insertion holes are provided corresponding to the plurality of electric wires, a plurality of the surrounding parts are provided corresponding to the plurality of electric wires and the plurality of temperature sensors, and the holder has a connecting part that connects the plurality of surrounding parts to each other.

With this configuration, since the multiple enclosing parts are connected to each other by the connecting parts, it is possible to reduce the number of parts compared to when the multiple enclosing parts are each individual parts.

[9] The surrounding portion has a third locking portion, the insertion hole has a fourth locking portion, and the third locking portion can be locked to the fourth locking portion in the direction in which the surrounding portion is removed from the insertion hole.

With this configuration, the third and fourth locking parts are engaged to prevent the surrounding part from slipping out of the insertion hole. In addition, because the surrounding part has a third locking part that can prevent the surrounding part from slipping out, it is not necessary to prevent the surrounding part from slipping out using a locking member separate from the holder, making it possible to prevent an increase in the number of parts.

[10] The connector includes a first seal member interposed between the electric wire and the insertion hole, the terminal has a first connection portion to which the electric wire is connected, the first seal member is provided between the first connection portion and the holder, the terminal has a fixing portion that fixes the first seal member to the outer peripheral surface of the electric wire, and the first seal member is provided away from the holder.

With this configuration, the first seal member is fixed to the outer circumferential surface of the electric wire by the fixing portion of the terminal, so there is no need for a separate member to press and fix the first seal member from the rear side. As a result, it is possible to suppress an increase in the number of parts. In addition, the holder is provided away from the first seal member, and the holder is not a member for fixing the first seal member.

[11] The connector includes a second seal member that covers a portion of the electric wire that is connected to the first connection portion.
According to this configuration, the second seal member covering the first connection portion can prevent the first connection portion from being exposed to water. Also, according to this configuration, it is not necessary to provide a rubber plug or the like on the front side of the first connection portion of the terminal, so it is possible to prevent an increase in the number of parts.

[12] The housing has a housing body and a holding member attached to the housing body, and the holding member has a terminal holding portion that holds the terminal and the insertion hole. With this configuration, it is possible to hold the terminal on the holding member attached to the housing body.

[13] The terminal has a first connection portion to which the electric wire is connected, a second connection portion to which a mating terminal is connected, and a fifth locking portion provided between the first connection portion and the second connection portion, and the terminal holding portion has a sixth locking portion that locks onto the fifth locking portion. With this configuration, the sixth locking portion of the holding member allows the terminal to be stably held by the holding member.

[14] The terminal can be assembled into the insertion hole from the rear side toward the front side of the holding member.
According to this configuration, after the terminal is attached to the electric wire, the terminal with the electric wire can be attached to the holding member from the rear side. Therefore, it is not necessary to perform the assembling work of the electric wire and the terminal in a state where the electric wire is passed through the holding member, and it is possible to improve the ease of assembly.

[15] The sixth locking portion includes a rear locking portion that restricts movement of the terminal toward the rear side of the holding member, and a front locking portion that restricts movement of the terminal toward the front side of the holding member.

With this configuration, the rear and front locking portions can restrict movement of the terminal to the rear and front of the holding member. This allows the terminal to be held more stably by the holding member.

[16] The fifth locking portion is formed in a flange shape protruding from the terminal, the rear locking portion can contact the rear side surface of the fifth locking portion, and the front locking portion can contact the front side surface of the fifth locking portion. With this configuration, the rear locking portion and the front locking portion are engaged with the flange-shaped fifth locking portion, making it possible to restrict movement of the terminal to the rear and front sides of the holding member.

The second retainer side locking portion 62 is a convex portion that protrudes 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.

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 from the insertion hole 53 into the second terminal holding portion 52.

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.

The housing body 26 has a fitting portion 26e into which the second terminal holding portion 52 fits. 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 of the elastic piece 61 opposite the side facing the second terminal 22B. The fitting portion 26e restricts the movement of the elastic piece 61 in the direction away from the second terminal 22B. In other words, the fitting portion 26e maintains the state in which the second retainer side locking portion 62 is locked to the second terminal side locking portion 45.

The first seal member 64b prevents water from entering the insertion hole 53 and the second terminal holding portion 52 from the rear side of the retainer 27. The fixing portion 46 of the second terminal 22B fixes the first seal member 64b to the surface of the electric wire 23. The fixing portion 46, for example, sandwiches a part of the first seal member 64b between the fixing portion 46 and the surface of the electric wire 23.

(Configuration of second seal members 65a, 65b)
The connector 20 includes, for example, second seal members 65a and 65b. As shown in Fig. 7, the second seal member 65a covers a portion of the electric wire 23 connected to the first connection portion 33 of the first terminal 22A. As shown in Fig. 10, the second seal member 65b covers a portion of the electric wire 23 connected to the first connection portion 43 of the second terminal 22B.

In the electric wire 23, the end of the core wire 23a is exposed from the insulating coating 23b. The end of the core wire 23a is connected to the first connection part 33. The second seal members 65a, 65b cover the end of the core wire 23a. The second seal members 65a, 65b are, for example, silicone resin, and are provided on the end of the core wire 23a by dripping or painting. The second seal members 65a, 65b waterproof the end of the core wire 23a between the wires. In other words, the second seal members 65a, 65b penetrate between the multiple strands at the end of the core wire 23a.

(Configuration of temperature sensor 24)
7, the temperature sensor 24 has a sensor body 24a and a lead wire 24b extending from the sensor body 24a. The sensor body 24a is attached to the surface of the electric wire 23 connected to the first terminal 22A. For example, a plurality of temperature sensors 24 are provided corresponding to the plurality of first terminals 22A, respectively. That is, there are two temperature sensors 24 in this embodiment.

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 corresponding to a temperature change via the lead wire 24b. The lead wire 24b is electrically connected to a control unit (not shown) that controls the charging of the battery 13 based on the signal from the sensor element.

(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.

The holder 25 has an enclosure 71 that holds the sensor main body 24a. For example, a plurality of enclosures 71 are provided corresponding to the plurality of first terminals 22A, respectively. That is, in this embodiment, there are two enclosures 71. The holder 25 also has, for example, a connecting portion 72 that connects the plurality of enclosures 71 to each other. The holder 25 is, for example, an injection-molded product made of synthetic resin.

As shown in FIG. 7, the surrounding portion 71 collectively covers the electric wire 23 and the sensor body 24a that is in contact with the surface of the electric wire 23. The surrounding portion 71 is inserted into the insertion hole 53 that is 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 body 24a. 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. The surrounding portion 71 is provided away from the first seal member 64a in the length direction of the electric wire 23.

As shown in Figures 13 and 14, the enclosure 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 body 24a in the direction in which the electric wire 23 and the sensor body 24a overlap.

The first division 73 has a first locking portion 75. Each of the multiple first divisions 73 has, for example, a pair of first locking portions 75. The second division 74 has a second locking portion 76. Each of the multiple second divisions 74 has, for example, a pair of second locking portions 76. The first locking portion 75 locks into the second locking portions 76, so that the first division 73 and the second division 74 are assembled together. In addition, when the first division 73 and the second division 74 are assembled together, the first division 73 and the second division 74 collectively cover the electric wire 23 and the sensor main body 24a.

As shown in Figures 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 first locking portion 75 and the second 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.

The surrounding portion 71 has, for example, a sensor holding portion 81 that holds the sensor 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 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 body 24a. When the first divided body 73 is not assembled to the second divided body 74, each claw portion 82 prevents the sensor 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.

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 together. Each of the first split bodies 73 and the first split connecting portion 83 is, for example, composed of a single part. The second split connecting portion 84 connects a pair of second split bodies 74 together. Each of the second split bodies 74 and the second split connecting portion 84 is, for example, composed of a single part.

The first split connecting part 83 has a positioning protrusion 83a. The positioning protrusion 83a fits into a positioning recess 84a of the second split connecting part 84. The second split connecting part 84 also has a positioning protrusion 84b. The positioning protrusion 84b fits into a positioning recess 83b of the first split connecting part 83.

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. In this way, 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.

7, the surrounding portion 71 is inserted into the insertion hole 53. The surrounding portion 71 has a third locking portion 85. The third locking portion 85 is, for example, a convex portion protruding from the outer circumferential surface of the surrounding portion 71. The third locking portion 85 is, for example, provided on each of the first division 73 and the second division 74. Meanwhile, the insertion hole 53 has a fourth locking portion 53a. A plurality of fourth locking portions 53a are provided corresponding to the third locking portion 85 of the first division 73 and the third locking portion 85 of the second division 74. The fourth locking portion 53a is, for example, a concave portion into which the third locking portion 85, which is a convex portion, is inserted. Each third locking portion 85 can be locked to each fourth locking portion 53a in the direction in which the surrounding portion 71 is removed from the insertion hole 53.

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 fixing portion 46 is crimped to fix the first seal member 64b to the electric wire 23.

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.

Next, the holder 25 and the temperature sensor 24 are attached to the electric wire 23. Here, the sensor body 24a is first 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 can be changed.

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 third locking portion 85 of the surrounding portion 71 is locked to the fourth locking 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. The electric wire 23 and the sensor body 24a are sandwiched between the first divided body 73 and the second divided body 74. This causes the sensor body 24a to be pressed against the surface of the electric wire 23.

Next, the retainer 27 is attached 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.

The effects of this embodiment will be described.
(1) The surrounding portion 71 of the holder 25 is interposed between the inner peripheral surface of the insertion hole 53 and the electric wire 23, and between the inner peripheral surface of the insertion hole 53 and the sensor main body 24a. With this configuration, if there is a design change in the diameter of the electric wire 23, it can be accommodated by changing the shape of the holder 25 side, such as 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. Note that 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 mold for the holder 25 compared to changing the mold for the housing 21 side.

(2) 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. With 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.

(3) The enclosing 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 body 24a in the direction in which the electric wire 23 and the sensor body 24a overlap. With this configuration, by sandwiching the electric wire 23 and the sensor body 24a between the first divided body 73 and the second divided body 74, the sensor body 24a can be pressed against the surface of the electric wire 23.

(4) The first division 73 has a first locking portion 75. The second division 74 has a second locking portion 76. The first locking portion 75 locks into the second locking portion 76, so that the first division 73 and the second division 74 are assembled to each other. With this configuration, the first division 73 and the second division 74 can be assembled to each other by the first locking portion 75 and the second locking portion 76, with the first division 73 and the second division 74 covering the electric wire 23 and the sensor main body 24a collectively.

(5) The surrounding portion 71 is configured to be able to change the distance between the first divided body 73 and the second divided 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 divided body 73 and the second divided body 74 can be made to have a margin with respect to the dimension obtained by adding the diameter of the electric wire 23 and the thickness of the sensor body 24a. This makes it possible for the first divided body 73, the second divided 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 divided body 73 and the second divided body 74 can be brought close to each other, so that the electric wire 23 and the sensor body 24a are sandwiched between the first divided body 73 and the second divided body 74, and the sensor body 24a can be pressed against the surface of the electric wire 23.

(6) 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 assembly of the temperature sensor 24 and the holder 25.

(7) The sensor holding portion 81 is formed on the first divided body 73. The sensor holding portion 81 holds the sensor body 24a attached to the first divided body 73 when the first divided body 73 is not attached to the second divided body 74. With this configuration, the first divided body 73 and the second divided body 74 can be assembled to the electric wire 23 with the sensor body 24a held by the sensor holding portion 81 of the first divided body 73. This makes it possible to improve the ease of assembly of the temperature sensor 24, the first divided body 73, and the second divided body 74.

(8) 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. With 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.

(9) The surrounding portion 71 has a third locking portion 85. The insertion hole 53 has a fourth locking portion 53a. The third locking portion 85 can be locked to the fourth locking portion 53a in the direction in which the surrounding portion 71 is removed from the insertion hole 53. With this configuration, the locking between the third locking portion 85 and the fourth locking portion 53a can prevent the surrounding portion 71 from slipping out of the insertion hole 53. In addition, since the surrounding portion 71 can be prevented from slipping out by the third locking portion 85 of the surrounding portion 71, it is not necessary to prevent the surrounding portion 71 from slipping out using a locking member separate from the holder 25, and it is possible to prevent an increase in the number of parts.

(10) The connector 20 includes a first seal member 64a interposed between the electric wire 23 and the insertion hole 53. The first seal member 64a is provided between the first connection portion 33 and the holder 25. The first terminal 22A has a fixing portion 36 that fixes the first seal member 64a to the outer peripheral surface of the electric wire 23. The first seal member 64a is provided away from the holder 25. According to this configuration, the first seal member 64a is fixed to the outer peripheral surface of the electric wire 23 by the fixing portion 36 of the first terminal 22A, so that 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. The holder 25 is provided away from the first seal member 64a, and the holder 25 is not a member for fixing the first seal member 64a. In addition, by fixing the first seal member 64a to the first terminal 22A, it is possible to position the first seal member 64a in the longitudinal direction of the electric wire 23.

(11) 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. In addition, with this configuration, it is not necessary to provide a rubber plug or the like on the front side of the first connection portions 33, 43, making it possible to prevent an increase in the number of parts.

(12) The housing 21 has a housing body 26 and a retainer 27 attached to the housing body 26. The retainer 27 has a first terminal holding portion 51 that holds the first terminal 22A, a second terminal holding portion 52 that holds the second terminal 22B, and an insertion hole 53. With this configuration, it is possible for the retainer 27 attached to the housing body 26 to hold the first terminal 22A and the second terminal 22B.

(13) The first terminal 22A has a first connection portion 33 to which the electric wire 23 is connected, a second connection portion 34 to which the mating terminal T1 is connected, and a first terminal side locking portion 35 provided between the first connection portion 33 and the second connection portion 34. The first terminal holding portion 51 has a first retainer side locking portion 55 that locks into the first terminal side locking portion 35. With this configuration, even before the retainer 27 is assembled to the housing body 26, the first retainer side locking portion 55 can stably hold the first terminal 22A to the retainer 27.

The second terminal 22B has a first connection portion 43 to which the electric wire 23 is connected, a second connection portion 44 to which the mating terminal T2 is connected, and a second terminal side locking portion 45 provided between the first connection portion 43 and the second connection portion 44. The second terminal holding portion 52 has a second retainer side locking portion 62 that locks with the second terminal side locking portion 45. With this configuration, even before the retainer 27 is assembled to the housing body 26, the second retainer side locking portion 62 can stably hold the second terminal 22B to the retainer 27.

(14) The terminal group 22 can be assembled into the insertion hole 53 from the rear side of the retainer 27 toward the front side. With this configuration, after the electric wire 23 is assembled to the terminal group 22, the terminal group 22 with the electric wire 23 can be assembled to the retainer 27 from the rear side. Therefore, it is not necessary to perform the assembly work of the electric wire 23 and the terminal group 22 while the electric wire 23 is passing through the retainer 27, and the ease of assembly can be improved.

(15) The first retainer side locking portion 55 includes a rear side locking portion 56 that restricts movement of the first terminal 22A toward the rear side of the retainer 27, and a front side locking portion 57 that restricts movement of the first terminal 22A toward the front side of the retainer 27. With this configuration, the rear side locking portion 56 and the front side 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 more stably in the retainer 27.

(16) The first terminal side locking portion 35 is formed in a flange shape that protrudes from the first terminal 22A. The rear side locking portion 56 can contact the rear side surface of the first terminal side locking portion 35. And the front side locking portion 57 can contact the 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, so that it is possible to restrict movement of the first terminal 22A to the rear side and the front side of the retainer 27.

(17) The first retainer side locking portion 55 restricts the movement of the first terminal 22A to the front and rear sides of the retainer 27 by locking 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.

The second retainer side locking portion 62, by locking with the second terminal side locking portion 45, restricts the movement of the second terminal 22B to the front and rear sides of the retainer 27. 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.

(18) 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.

(19) The second terminal side locking portion 45 is provided on the metal portion 41 of the second terminal 22B. With this configuration, the second terminal side locking portion 45 can be formed on the metal portion 41 of the second terminal 22B.

(20) 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. With this configuration, the second terminal side locking portion 45 provided on the metal portion 41 of the second terminal 22B is locked with the second retainer side locking portion 62, which is a protrusion of the retainer 27, thereby making it possible to appropriately restrict the movement of the second terminal 22B.

(21) The second terminal 22B has a protruding wall 47 that protrudes in a direction intersecting the length direction of the second connection portion 44. The second terminal side locking portion 45 is a hole that penetrates the protruding wall 47. With this configuration, the second terminal side locking portion 45, which is a hole provided in the protruding wall 47, is locked with the second retainer side locking portion 62, which is a protrusion of the retainer 27, thereby making it possible to appropriately restrict the movement of the second terminal 22B.

(22) The first terminal 22A has a resin portion 32 that is integral with the metal portion 31. The first terminal side locking portion 35 is provided on the resin portion 32. With this configuration, the first terminal side locking portion 35 can be formed on the resin portion 32 of the first terminal 22A.

(23) When the second connection portion 44 side relative to the first connection portion 43 of the second terminal 22B is considered to be 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 peripheral surface of the electric wire 23. With this configuration, the first seal member 64b is fixed to the second terminal 22B, making it possible to position the first seal member 64b in the length direction of the electric wire 23.

(24) The retainer 27 has a guide portion 58 that guides the first terminal side locking portion 35 to the rear side locking portion 56 when the first terminal 22A is inserted into the insertion hole 53.
