According to this configuration, the fixed portion of the metal connecting member is fixed to the terminal by the metal fixing member. Therefore, heat can be efficiently transmitted from the terminal to the temperature sensor member by the metal connecting member and the metal fixing member. As a result, in the terminal assembly mounted on the charging connector, the accuracy of detecting the temperature of the terminal can be improved.
[2] The terminal has: a 1 st electrical connection portion connectable to a counterpart terminal; a 2 nd electrical connection portion connectable to the conductive member; and an intermediate portion provided between the 1 st electrical connection portion and the 2 nd electrical connection portion, the connection member having a sensor fixing portion at which the temperature sensor member is fixed, the sensor fixing portion being in contact with the intermediate portion.
According to this structure, the sensor fixing portion of the connecting member is in contact with the intermediate portion of the terminal. Therefore, heat can be more efficiently transferred from the terminal to the temperature sensor member. As a result, the accuracy of the temperature detection of the terminal can be further improved.
[3] The intermediate portion has a 1 st surface facing the connection member and a 2 nd surface opposite to the 1 st surface, the connection member has an extension portion extending from the sensor fixing portion, the sensor fixing portion is in contact with the 1 st surface, and the extension portion is in contact with the 2 nd surface.
According to this structure, the connecting member sandwiches the intermediate portion of the terminal from the 1 st surface side and the 2 nd surface side by the sensor fixing portion and the extending portion. Therefore, the connecting member is firmly fixed to the intermediate portion of the terminal, and as a result, the assembled state of the connecting member can be stabilized. Further, the extending portion is in contact with the 2 nd surface of the intermediate portion, whereby the sensor fixing portion can be prevented from being separated from the 1 st surface of the intermediate portion. That is, the sensor fixing portion can be maintained in contact with the 1 st surface by the extending portion.

According to this configuration, when the fixed portion of the connecting member is fixed to the terminal by screwing the screw, the 1 st extending portion of the connecting member can be brought into contact with the terminal. Therefore, the 1 st extension part can be used for preventing the connecting component and the screw from being carried back and forth and dislocated.
[5] The connecting member has a 2 nd extending portion extending from the 1 st extending portion, and the 2 nd extending portion is opposed to the 2 nd surface and contactable with the 2 nd surface.
According to this configuration, the 2 nd extending portion comes into contact with the 2 nd surface of the intermediate portion, whereby the sensor fixing portion can be prevented from separating from the 1 st surface of the intermediate portion.

[7] The connecting member has a 4 th extension portion extending from the 3 rd extension portion, and the 4 th extension portion is opposed to the 2 nd surface and contactable with the 2 nd surface.
According to this configuration, the 4 th extending portion is in contact with the 2 nd surface of the intermediate portion, and the sensor fixing portion can be prevented from being separated from the 1 st surface of the intermediate portion. That is, the state in which the sensor fixing portion is in contact with the 1 st surface can be maintained by the 4 th extending portion. As a result, the accuracy of the temperature detection of the terminal can be further improved.
[8] The terminal assembly includes an adhesive for adhering the temperature sensor member to the connecting member, and the adhesive is a thermosetting resin.

According to this configuration, the fixed portion of the metal connecting member is fixed to the terminal by the metal fixing member. Therefore, heat can be efficiently transmitted from the terminal to the temperature sensor member by the metal connecting member and the metal fixing member. As a result, in the terminal assembly mounted on the charging connector, the accuracy of detecting the temperature of the terminal can be improved.

The intermediate portion 23 has a pair of side surfaces 23c shown in fig. 3. Each side surface 23c is a surface connecting the 1 st surface 23a and the 2 nd surface 23 b. The side surfaces 23c are provided on both widthwise edges of the intermediate portion 23.
(Structure of connecting member 30)
The connecting member 30 is made of metal. The connecting member 30 is formed by, for example, press working a metal plate. The connecting member 30 has a fixed portion 31, a sensor fixing portion 32, a 1 st extending portion 33, and a 2 nd extending portion 34.
As shown in fig. 5, the fixed portion 31 is fixed to the intermediate portion 23 by a fixing member 50. The fixed portion 31 has, for example, a through hole 31a through which the fixed portion 31 passes.
The fixing member 50 is made of metal. The fixing member 50 is, for example, a screw. That is, the fixing member 50 has a threaded portion 51 having a thread on an outer peripheral surface. On the other hand, a screw groove, not shown, for example, is formed on the inner peripheral surface of the fixing hole 24 of the intermediate portion 23. The screw portion 51 is inserted through the through hole 31a of the fixed portion 31 and screwed into the fixing hole 24. Thereby, the fixed portion 31 is fixed to the 1 st surface 23a of the intermediate portion 23 in a state of contact therewith.
The sensor fixing portion 32 is connected to the fixed portion 31. The sensor fixing portion 32 is fixed with the sensor main body portion 41 of the temperature sensor member 40. The sensor fixing portion 32 has a 3 rd surface 32a and a 4 th surface 32b on the opposite side of the 3 rd surface 32 a. The sensor body 41 is fixed to the 3 rd surface 32 a. The 4 th surface 32b is in direct contact with the 1 st surface 23a of the intermediate portion 23.
As shown in fig. 3, in a state where the connecting member 30 is fixed to the terminal 20, the fixed portion 31 and the sensor fixing portion 32 are aligned in, for example, the longitudinal direction of the terminal 20. The fixed portion 31 is located on the 1 st electrical connection portion 21 side, and the sensor fixing portion 32 is located on the 2 nd electrical connection portion 22 side.
As shown in fig. 4, the sensor fixing portion 32 has, for example, a wall portion 35 protruding from the 3 rd surface 32 a. The wall portion 35 is provided with a pair, for example. The pair of wall portions 35 face each other in the width direction orthogonal to the longitudinal direction of the terminal 20. The sensor body 41 is accommodated between the pair of wall portions 35.
The terminal assembly 17 includes an adhesive 60 that adheres the sensor body 41 to the connecting member 30. The sensor main body portion 41 is bonded to the sensor fixing portion 32 with an adhesive 60. The adhesive 60 is, for example, a thermosetting resin. As the adhesive 60, for example, an epoxy resin or the like can be used.
The adhesive 60 is applied to, for example, the 3 rd surface 32a of the sensor fixing portion 32 or the surface of the sensor main body portion 41 facing the 3 rd surface 32 a. Each wall portion 35 functions to block the adhesive 60 pushed out from between the sensor main body portion 41 and the 3 rd surface 32 a. Each wall portion 35 serves to position the sensor body portion 41 on the sensor fixing portion 32.
The wall portion 35 has, for example, a positioning portion 36 shown in fig. 5. The positioning portion 36 extends from the end portion of the wall portion 35 on the fixed portion 31 side, for example. The positioning portion 36 is in contact with the sensor main body portion 41 in the longitudinal direction of the terminal 20. Thereby, the sensor main body portion 41 is positioned in the longitudinal direction of the terminal 20. The positioning portion 36 is provided on each wall portion 35, for example.
As shown in fig. 4 and 5, the 1 st extension portion 33 extends from the sensor fixing portion 32, for example. The 1 st extending portion 33 extends from, for example, a side surface of the sensor fixing portion 32 that connects the 3 rd surface 32a and the 4 th surface 32 b. The 1 st extending portion 33 is provided at an end portion of the sensor fixing portion 32 on the opposite side to the fixed portion 31.
The 1 st extending portion 33 extends from the 1 st surface 23a side toward the 2 nd surface 23b side in the intermediate portion 23. The 1 st extending portion 33 faces one side surface 23c of the intermediate portion 23 in the rotational direction toward the fixing side of the fixing member 50 as a screw. The rotation direction toward the fixing side of the fixing member 50 is, for example, a clockwise direction D1 centered on the axis of the fixing member 50 as viewed from the head side of the screw. The 1 st extending portion 33 can contact one side surface 23c of the intermediate portion 23.
The 2 nd extension 34 extends from the 1 st extension 33. The 2 nd extending portion 34 is, for example, a bent portion. The 2 nd extending portion 34 extends from the tip end portion of the 1 st extending portion 33 along the 2 nd surface 23b of the intermediate portion 23, for example. The 2 nd extending portion 34 is opposed to the 2 nd surface 23b and can contact the 2 nd surface 23 b. In a state where the 4 th surface 32b of the sensor fixing portion 32 is in contact with the 1 st surface 23a of the intermediate portion 23, for example, a gap may be generated between the 2 nd surface 23b of the intermediate portion 23 and the 2 nd extending portion 34. In addition, in a state where the connecting member 30 is detached from the terminal 20, the 2 nd extending portion 34 faces the 4 th surface 32b of the sensor fixing portion 32.
The operation of the present embodiment will be described.
For example, when the routing path of the signal wire 42 of the temperature sensor member 40 is set in a direction away from the 1 st surface 23a of the intermediate portion 23, the sensor body 41 and the connecting member 30 are pulled by the signal wire 42, and the connecting member 30 is urged in a direction away from the 1 st surface 23 a. In this case, in the present embodiment, the 2 nd extending portion 34 of the connecting member 30 is in contact with the 2 nd surface 23b of the intermediate portion 23, so that the sensor fixing portion 32 can be prevented from separating from the 1 st surface 23 a. This can maintain the sensor fixing portion 32 in contact with the 1 st surface 23 a.
When the connecting member 30 is fixed to the terminal 20, the fixing member 50 as a screw is attached in the clockwise direction D1. At this time, it is possible that the connecting member 30 is brought back and forth with the fixing member 50 in the clockwise direction D1, but in the present embodiment, the 1 st extending portion 33 contactable with the side surface 23c of the intermediate portion 23 functions as a stopper. This can suppress the connecting member 30 from being moved back and forth when the fixing member 50 is fixed.
The effects of the present embodiment will be described.
(1) The connecting member 30 holding the temperature sensor member 40 is made of metal. The fixed portion 31 of the connecting member 30 is fixed to the terminal 20 by a metal fixing member 50. That is, the metal connecting member 30 and the metal fixing member 50 can effectively transmit heat from the terminal 20 to the temperature sensor member 40. As a result, the accuracy of detecting the temperature of the terminal 20 can be improved in the terminal assembly 17 mounted on the charging connector 15.
(2) The terminal 20 has a 1 st electrical connection portion 21 connectable to a counterpart terminal T, a 2 nd electrical connection portion 22 connectable to the conductive member C, and an intermediate portion 23 provided between the 1 st electrical connection portion 21 and the 2 nd electrical connection portion 22. The connecting member 30 has a sensor fixing portion 32, and the temperature sensor member 40 is fixed to the sensor fixing portion 32. The sensor fixing portion 32 is in contact with the intermediate portion 23. According to this structure, the sensor fixing portion 32 of the connecting member 30 is in contact with the intermediate portion 23 of the terminal 20. Therefore, heat can be more efficiently transferred from the terminal 20 to the temperature sensor member 40. As a result, the accuracy of the temperature detection of the terminal 20 can be further improved.
(3) The intermediate portion 23 has a 1 st surface 23a opposed to the connecting member 30, a 2 nd surface 23b on the opposite side of the 1 st surface 23a, and a fixing hole 24 recessed from the 1 st surface 23 a. The fixing member 50 is a screw fixed to the fixing hole 24. The fixed portion 31 is fixed to the intermediate portion 23 by a fixing member 50 as a screw. The connecting member 30 has a 1 st extending portion 33 extending from the 1 st surface 23a side toward the 2 nd surface 23b side. The 1 st extending portion 33 faces the terminal 20 in the rotational direction toward the fixing member 50. According to this configuration, when the fixed portion 31 of the connecting member 30 is fixed to the terminal 20 by screwing a screw, the 1 st extending portion 33 of the connecting member 30 can be brought into contact with the terminal 20. Therefore, the 1 st extending portion 33 can prevent the connecting member 30 from being displaced from the screw due to the back and forth movement.
The 1 st extending portion 33 is provided at an end portion of the sensor fixing portion 32 on the opposite side to the fixed portion 31. This allows the 1 st extending portion 33 to be set at a position further apart from the fixed portion 31. Therefore, the following structure is obtained: when the connecting member 30 is to be brought back and forth with the fixing member 50 at the time of fixing of the fixing member 50, the 1 st extending portion 33 appropriately prevents the force of the bringing back and forth.
(4) The connecting member 30 has a 2 nd extension 34 extending from the 1 st extension 33. The 2 nd extending portion 34 faces the 2 nd surface 23b and can contact the 2 nd surface 23 b. According to this configuration, the 2 nd extending portion 34 is in contact with the 2 nd surface 23b of the intermediate portion 23, and thus the sensor fixing portion 32 can be prevented from separating from the 1 st surface 23a of the intermediate portion 23. That is, the state in which the sensor fixing portion 32 is in contact with the 1 st surface 23a can be maintained by the 2 nd extending portion 34. As a result, the accuracy of temperature detection of the terminal 20 can be further improved.
(5) The terminal assembly 17 includes an adhesive 60 that adheres the temperature sensor member 40 to the connecting member 30. The adhesive 60 is a thermosetting resin. According to this configuration, the temperature sensor member 40 is integrated with the connecting member 30 by using a thermosetting resin as the adhesive 60. Therefore, the terminal assembly 17 is more suitable as the charging connector 15 that can be heated to a high temperature.
This embodiment can be modified as follows. The present embodiment and the following modifications can be combined and implemented within a range not technically contradictory to each other.
■ may have the following structure: in a state where the 4 th surface 32b of the sensor fixing portion 32 is in contact with the 1 st surface 23a of the intermediate portion 23, the 2 nd extending portion 34 is in contact with the 2 nd surface 23b of the intermediate portion 23. According to this structure, the intermediate portion 23 of the terminal 20 is sandwiched from the 1 st surface 23a side and the 2 nd surface 23b side by the sensor fixing portion 32 and the 2 nd extending portion 34. Thereby, the connecting member 30 is firmly fixed to the intermediate portion 23. As a result, the assembled state of the connecting member 30 and the temperature sensor member 40 can be stabilized.
■ the 1 st extending portion 33 of the above embodiment is configured to be able to contact the side surface 23c of the intermediate portion 23, but is not particularly limited thereto. For example, the 1 st extension portion may be inserted into a through hole penetrating the intermediate portion 23. In this configuration, the 1 st extension portion is in contact with the through hole, so that the connecting member 30 can be prevented from being moved back and forth when the fixing member 50 is fixed.
■ in the connecting member 30 of the above embodiment, the 2 nd extending portion 34 may be omitted. In the connecting member 30 of the above embodiment, the 1 st extending portion 33 may be omitted. When the 2 nd extending portion 34 is omitted, the sensor fixing portion 32 may be easily separated from the terminal 20. However, since the connecting member 30 and the fixing member 50 are made of metal, and the fixed portion 31 fixed to the terminal 20 by the fixing member 50 is in contact with the terminal 20, heat can be efficiently transmitted from the terminal 20 to the temperature sensor member 40 through the fixed portion 31.
■ in the connecting member 30 of the above embodiment, for example, a 3 rd extending portion 71 and a 4 th extending portion 72 shown in fig. 6 may be additionally provided.
As shown in fig. 6, the 3 rd extending portion 71 extends from the sensor fixing portion 32, for example. The 3 rd extending portion 71 extends from, for example, a side surface of the sensor fixing portion 32 that connects the 3 rd surface 32a and the 4 th surface 32 b. The 3 rd extending portion 71 extends from a side surface of the sensor fixing portion 32 on the opposite side to the side surface on which the 1 st extending portion 33 is provided. The 3 rd extending portion 71 is provided at an end portion of the sensor fixing portion 32 on the opposite side to the fixed portion 31.
The 3 rd extending portion 71 extends from the 1 st surface 23a side toward the 2 nd surface 23b side in the intermediate portion 23. The 3 rd extending portion 71 faces one side surface 23c of the intermediate portion 23 in the rotational direction toward the slack side of the fixing member 50. The rotation direction toward the loosening side of the fixing member 50 is, for example, a counterclockwise direction D2 centered on the axis of the fixing member 50 as viewed from the head side of the screw. The 3 rd extending portion 71 can contact one side surface 23c of the intermediate portion 23. The side surface 23c with which the 3 rd extending portion 71 can contact is the side surface 23c on the opposite side to the side surface 23c with which the 1 st extending portion 33 can contact.
The 4 th extension 72 extends from the 3 rd extension 71. The 4 th extending portion 72 is, for example, a bent portion. The 4 th extending portion 72 extends from the tip end portion of the 3 rd extending portion 71 along the 2 nd surface 23b of the intermediate portion 23, for example. The 4 th extending portion 72 is opposed to the 2 nd surface 23b and can contact the 2 nd surface 23 b.
According to the structure shown in fig. 6, the 3 rd extending portion 71 of the connecting member 30 can be brought into contact with the terminal 20 in the rotational direction of the slack side of the fixing member 50. Therefore, the 3 rd extending portion 71 can suppress loosening of the screw. Further, the 4 th extending portion 72 is in contact with the 2 nd surface 23b of the intermediate portion 23, so that the sensor fixing portion 32 can be prevented from being separated from the 1 st surface 23a of the intermediate portion 23. As a result, the accuracy of temperature detection of the terminal 20 can be further improved. In the structure shown in fig. 6, the 2 nd extension 34 or the 4 th extension 72 can be omitted.
■ the fixing method of the sensor main body 41 to the sensor fixing portion 32 is not limited to the adhesion using the adhesive 60, and may be a fixing method other than the adhesion.
■ in the above embodiment, the fixed portion 31 of the connecting member 30 is fixed to the intermediate portion 23 of the terminal 20 by screwing the threaded portion 51 of the fixing member 50 into the fixing hole 24 of the terminal 20. However, in addition to this, for example, the fixing hole 24 may not have a screw groove, and the fixed portion 31 may be fixed to the intermediate portion 23 by screwing a nut from the 2 nd surface 23b side of the intermediate portion 23 with respect to the screw portion 51 inserted through the through hole 31a and the fixing hole 24. In addition, when the fixing member 50 is made of metal, for example, a rivet or the like other than a screw or a bolt can be used.
■, although the sensor fixing portion 32 is configured to contact the intermediate portion 23 of the terminal 20 in the above embodiment, the present invention is not limited to this, and for example, the sensor fixing portion 32 may be configured to contact the 1 st electrical connection portion 21.
■ in the above embodiment, the fixed portion 31 of the connecting member 30 is fixed to the intermediate portion 23 of the terminal 20, but other than this, for example, the fixed portion 31 may be fixed to the 1 st electrical connection portion 21 of the terminal 20.
■ the terminal assembly 17 according to the above embodiment is used for the charging connector 15 of the vehicle 10, but is not limited to this and may be used for connectors other than the charging connector 15 in the vehicle 10.
■ the embodiment and the modification disclosed herein are not intended to be limiting but are merely illustrative in all respects. The scope of the present invention is defined not by the above description but by the appended claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.
