Description

  The present invention relates to a feeding connector and a feeding connector with a cable in which the feeding connector is provided at a power cable terminal.

For example, when charging a battery of an electric car, a cable-equipped power supply connector having a configuration in which a terminal of a cable (hereinafter, power supply cable) can be fitted with a connector (hereinafter, power supply connector) that can be fitted to the car inlet is used. A method of connecting from the outside and charging the battery is widely adopted.
The feed connector has a power terminal (hereinafter also referred to as a connector terminal) to which the conductor of the feed cable is electrically connected (for example, Patent Document 1). The inlet of the automobile incorporates a power terminal (hereinafter also referred to as an inlet terminal) connected to the battery through electrical wiring in the automobile body. When the feed connector is fitted to the inlet of the car, the connector terminal is fitted to the inlet terminal, and the conductor of the feed cable is electrically connected to the battery.

A quick charging power supply connector (hereinafter also referred to as a quick charging connector) usually supplies power through two power terminals.
The power terminal of the quick charge connector is connected to the conductor of the feed cable by compression, crimping, screwing or the like. The dimensions and shape of the power terminal of the quick charge connector are determined by the standard. The power terminal of the quick charge connector is required to have a low insertion force in order to repeat insertion and removal smoothly to the inlet terminal. In addition, the power terminal of the quick charging connector is required to have low electrical resistance in order to conduct a large current.

In recent years, the battery capacity of electric vehicles has been increasing, and accordingly, charging with a larger current has been considered. When the connector terminal is used for charging with a large current without changing its shape, Joule heat countermeasures by large current conduction become a problem. Excessive temperature rise due to heat generation of the connector terminal leads to oxidation of the connector terminal and an increase in resistance value, leading to shortening of the life of the connector terminal. For example, according to the standard (IEC 62196-124.), The temperature rise during energization of the quick charging connector used in an electric vehicle (EV) is determined to have a rise value of 50 K or less.
It is possible to cope with the heat generation of the conductor of the feeding cable by energization by thickening the conductor or cooling the conductor by flowing a coolant through a tube built in the cable. On the other hand, it is difficult for the connector terminal to suppress heat generation due to energization without changing the terminal shape. In addition, it is conceivable to cool the connector terminal by flowing cooling water near the connector terminal, but there is a large space constraint to make it compatible with the conventional shape, which is very difficult to design, and a practical solution It is the fact that it does not become a measure.

  Patent Document 1 discloses a configuration in which a plurality of terminals are collectively supported on a shell member 1000 forming a part of a flow path of a cooling fluid to prevent a temperature rise of the terminals. However, in this configuration, the metal shell member 1000 having excellent thermal conductivity such as copper can not be used in order to ensure the electrical insulation of the shell member 1000 in terms of preventing the electrical short between the terminals. For this reason, the terminal cooling efficiency is low and application to a connector used for charging with a large current is not practical.

The second fixed end portion 13c is located at a position farther from the central axis of the contact portion 12c of the connector terminal 12 (the separation distance from the central axis of the contact portion 12c is larger) than that of the first fixed end 13b. The second fixed end 13 c is fixed to an end on one side in the axial direction of the cylindrical heat collecting member 141 (specifically, an end on the connector terminal 12 side. A front end). The heat conducting member 13 connects and connects between the connector terminal 12 and the heat collecting member 141. The heat collecting member 141 is fixed to the connector terminal 12 via the heat conducting member 13.

The heat conducting member 13 and the heat collecting member 141 are members made of metal such as copper and aluminum which are excellent in thermal conductivity. The heat collecting member 141 is connected to the connector terminal 12 via the heat conducting member 13 so as to be able to transfer heat (heat transfer). The heat conducting member 13 serves to guide the heat generated at the time of energization of the connector terminal 12 to the heat collecting member 141.
The heat conducting member 13 is fixed to the connector terminal 12 and the heat collecting member 141 by welding, screwing or the like.

In addition, it is common in the other embodiment which concerns on this invention to use the metal-made members which are excellent in heat conductivity, such as copper and aluminum, for the heat-conduction member 13 and the heat-collection member 141. FIG.
Further, fixing the heat conductive member 13 to the connector terminal 12 and the heat collecting member 14 by welding, screwing or the like is common to the other embodiments according to the present invention.

As shown in FIG. 2, a heat insulating interposed member 18 is provided between the inner peripheral surface (inner peripheral surface) of the heat collecting member 141 and the feeding cable 21. In the heat collection member 141, the separation distance between the inner circumferential surface thereof and the feed cable 21 is secured by the interposition member 18, and does not contact the feed cable 21.
For the interposing member 18, a member having a good heat insulating property such as a foamed resin body (foamed polystyrene or the like) is preferably employed. Specifically, the interposing member 18 of FIG. 2 is expanded polystyrene. However, as the foamed resin body forming the interposition member 18, for example, foamed polyurethane, foamed polyethylene and the like can be adopted in addition to the foamed polystyrene.

The fluid conduit 15 of the cable-equipped power supply connector 20A shown in FIG. 1 is, for example, a tube made of synthetic resin such as nylon, fluorine resin, urethane resin, or silicone resin.
At the central portion in the longitudinal direction of the fluid conduit 15, a conduit heat receiving portion 15a spirally disposed in contact with the outer peripheral surface of the cylindrical heat collecting member 141 is secured.

The fluid conduit 15 is a tube (cooling tube) for circulating a fluid such as water and removing the heat conducted to the heat collecting member 141.
The fluid line 15 is not limited to one entirely made of synthetic resin. The fluid conduit 15 adopts, for example, a conduit heat receiving portion 15a which is a metal tube made of a metal excellent in thermal conductivity such as copper, aluminum or the like, and made of synthetic resin at both ends of the conduit heat receiving portion 15a. A configuration in which a tube is connected can also be adopted.

Grease (hereinafter also referred to as heat transfer grease) in which a metal filler excellent in thermal conductivity such as copper or aluminum is mixed around the contact portion between the heat collection member 141 and the fluid conduit 15 shown in FIG. It is provided. The heat transfer grease fills a minute gap between the heat collecting member 141 and the fluid conduit 15 and increases the amount of heat transferred from the heat collecting member 141 to the fluid conduit 15.
In addition, the structure which is not provided with heat-transfer grease can also be employ | adopted for the electric power feeding connector 20A with a cable.

  As indicated by a phantom line (two-dot chain line) in FIG. 2, the cable-equipped power supply connector 20A is concentric with the heat collecting member 141 so as to cover the pipe heat receiving portion 15a of the fluid conduit 15 outside the heat collecting member 141. A configuration in which the disposed cover member 16 is provided and the region between the heat collection member 141 and the cover member 16 is embedded by the heat transfer grease 14 a can also be suitably adopted. In this configuration, the conduit heat receiving portion 15a of the fluid conduit 15 is provided in the heat transfer grease 14a in which the region between the heat collecting member 141 and the cover member 16 (hereinafter also referred to as the conduit accommodating region 17) is embedded. To position.

Hereinafter, the heat collecting member 141 provided with the cover member 16 and the heat transfer grease 14a for embedding the conduit housing area 17 is also referred to as a heat collecting member 141A with a cover.
The heat transfer grease 14a in the conduit housing area 17 of the heat collection member 141A with cover is a conduit of the fluid conduit 15 for heat radiated from a portion of the outer peripheral surface of the heat collection member 141 not in contact with the fluid conduit 15. It transmits to the heat receiving part 15a. The heat collection member 141A with a cover uses the heat transfer grease 14a for the heat of the portion of the heat collecting member 141 not in contact with the pipe heat receiving portion 15a, in addition to the heat of the portion of the heat collecting member 141 in contact with the pipe heat receiving portion 15a. Thus, the heat can be transmitted to the pipe heat receiving portion 15 a of the fluid pipe 15.

  For this reason, the heat collection member 141A with a cover is compared with the heat collection member 141 in which the heat transfer grease 14a for embedding the cover member 16 and the conduit accommodation area 17 is not provided. It is possible to increase the amount of heat transferred. The heat collection member 141A with a cover is the connector terminal 12 and the heat collection member 141 that generate heat by energization as compared with the heat collection member 141 in which the heat transfer grease 14a for embedding the pipe housing area 17 is not provided. Temperature rise suppression can be realized more reliably.

  Both ends of the fluid line 15 are connected to the fluid circulation heat exchange device 31 and are communicated with each other via a flow path in the fluid circulation heat exchange device 31 (hereinafter, a device internal flow path). The fluid circulation heat exchange device 31 feeds the fluid into the fluid line 15 from one end thereof and receives the fluid from the other end of the fluid line 15.

The fluid circulation heat exchange device 31 has a heat exchange portion for preventing the temperature of the fluid flowing in the device internal flow passage from becoming a considerably high temperature from normal temperature, and the fluid of the device internal flow passage in the fluid conduit 15 at one end side thereof And a pump unit for feeding from the
The heat exchange unit plays a role of maintaining the temperature of the fluid sent from the apparatus internal flow path to the fluid conduit 15 at normal temperature (5 to 35 ° C.) or below normal temperature by water cooling or air cooling etc. of members formed with the apparatus internal flow path. Play.

The cable-equipped power supply connector 20A has a circulation path (a fluid flow path; hereinafter also referred to as a fluid circulation path) configured by the device internal flow path of the fluid circulation heat exchange device 31 and the fluid line 15, and circulating a fluid. The inner space of the fluid line 15 constitutes a part of the fluid circulation path (fluid flow path).
The fluid circulation heat exchange device 31 circulates the fluid in the fluid circulation path.

  As described above, the cable-equipped power supply connector 20 </ b> A can guide the heat of the connector terminal 12, which is generated due to the electric conduction, to the heat collection member 141 via the heat conductive member 13. The heat of the heat collection member 141 is transferred (heat transfer) from the heat receiving portion 15a of the fluid passage 15 to the fluid flowing inside thereof. The cable-equipped power supply connector 20A transports the heat of the heat collecting member 141 from the pipe heat receiving portion 15a of the fluid pipe 15 by the fluid circulated in the fluid circulation path to suppress the temperature rise of the heat collecting member 141 (collector Cool the heat member 141).

  The fluid circulation heat exchange device 31 is located outside the power supply connector 10A. The cable-equipped power supply connector 20A allows the fluid flowing inside the fluid conduit 15 to discharge the heat of the heat collection member 14 out of the housing 11. The fluid line 15 is an example of a heat removal means for discharging the heat of the heat collection member 14 out of the housing 11.

  The cable-equipped power supply connector 20A indirectly cools the connector terminal 12 that generates heat due to the electric conduction through the heat conducting member 13 and the heat collecting member 141 instead of directly cooling, and suppresses the temperature rise of the connector terminal 12.

  As described above, the heat collecting member 141 has the separation distance between the power feeding cable 21 and the interposing member 18 provided between the inner peripheral surface thereof and the power feeding cable 21, and does not contact the power feeding cable 21. . Therefore, heat transfer from the heat collecting member 141 to the feeding cable 21 does not occur in the cable feeding connector 20A.

In a configuration in which the heat collecting member 141 is in contact with the feeding cable 21, the temperature of the cable conductor 21a may increase due to heat transfer from the heat collecting member 141 to the feeding cable 21, which may increase the resistance of the conductor 21a. .
On the other hand, in the cable-equipped power supply connector 20A of FIG. 1, since the separation distance between the heat collection member 141 and the power supply cable 21 is secured and the heat collection member 141 does not contact the power supply cable 21, There is no direct heat transfer to the feed cable 21. For this reason, the cable-equipped power supply connector 20A of FIG. 1 is advantageous for preventing the temperature rise and the resistance increase of the cable conductor 21a due to the heat transfer from the heat collecting member 141 to the power supply cable 21.

The feed connector and the feed connector with a cable may have a configuration in which the duct heat receiving portion 15a is arranged along and in contact with the inner peripheral surface of the cylindrical heat collecting member 141.
When the conduit heat receiving portion 15 a is disposed along the inner peripheral surface of the cylindrical heat collecting member 141, the conduit heat receiving portion 15 a is disposed apart from the feeding cable 21.
The duct heat receiving portion 15 a disposed along the inner peripheral surface of the cylindrical heat collecting member 141 is located in the region between the heat collecting member 141 and the feeding cable 21. In terms of securing the maintainability of the duct heat receiving portion 15 a, the duct heat receiving portion 15 a is disposed along the outer peripheral surface of the heat collecting member 141 rather than the configuration in which the duct heat receiving portion 15 a is disposed along the inner circumferential surface of the heat collecting member 141. A configuration in which all of them are arranged is advantageous.

The heat collecting member of the power supply connector is not limited to the cylindrical one illustrated in FIG.
The heat collecting member of the feed connector may be, for example, a flat member as shown in FIG.
FIG. 3 shows a feeding connector 10B and a feeding connector 20B (with a feeding connector and a cable with a configuration in which a flat heat collecting member 14 is employed instead of the heat collecting member 141 of the cable feeding connector 20A of the first embodiment). 2 shows a second embodiment of the feed connector.

The heat collecting member 142 is fixed to the connector terminal 12 via the heat conducting member 13 by fixing a part of the outer peripheral portion in the surface direction to the second fixed end 13 c of the heat conducting member 13. The heat collecting member 142 is supported by the connector terminal 12 via the heat conducting member 13. The heat collecting member 142 is separated from the feeding cable 21 and supported.

Specifically, the heat collecting member 142 of FIG. 3 is formed in a rectangular plate shape. One end in the longitudinal direction of the heat collecting member 142 in FIG. 3 is fixed to the second fixed end 13 c of the heat conducting member 13, and the longitudinal direction is aligned with the central axis of the connector terminal 12.
In FIG. 3, a portion of the feeding cable 21 located on the rear side of the connector terminal 12 is disposed in the housing 11 so as to extend along the central axis of the connector terminal 12. However, in the feed connector 10B and the feed connector with cable 20B of this embodiment, the portion of the feed cable 21 located on the rear side of the connector terminal 12 is a heat collecting member in the housing 11 as it goes from the connector terminal 12 to the rear side. It is also possible to bend and accommodate away from 142.

The power supply connector 10B and the cable-equipped power supply connector 20B of FIG. 3 also include a fluid conduit 15 disposed along a portion of the heat collection member 142 in the longitudinal direction.
As shown in FIG. 3, the fluid conduit 15 has a conduit heat receiving portion 15 a disposed extending on one side of the heat collecting member 142. The duct heat receiving portion 15 a is provided in contact with the heat collecting member 142.
In FIG. 3, the conduit heat receiving portion 15 a is disposed so as to meander on a surface (hereinafter, also referred to as an outer main surface) of the heat collecting member 142 opposite to the feeding cable 21.

The present invention is also applicable to a configuration in which the portion 15a is extended.

  The feed connector and the feed connector with cable are not limited to the configuration in which the pipe heat receiving portion 15a of the fluid pipe 15 is disposed along the outer surface of the heat collecting member. As shown in FIGS. 5 and 6, the feed connector and the feed connector with cable may employ a configuration in which a space 14b directly formed in the heat collecting member 14 is a fluid flow path for flowing a fluid.

  The feed connector 10C and the feed connector with cable 20C (third embodiment of the feed connector and the feed connector with cable) shown in FIG. 5 have a heat collecting member 14 (in FIG. 5, reference numerals in FIG. 5) having a space 14b functioning as a fluid flow channel. 143). The feeding connector 10C and the feeding connector with cable 20C shown in FIG. 5 are the same as the feeding connector 10A of the first embodiment and the feeding connector with cable 20A in the heat collecting member 143 in which a space 14b is formed which functions as a fluid flow path. It is a change. Further, the power supply connector 10C and the cable-equipped power supply connector 20C shown in FIG. 5 do not have the fluid pipe line 15 securing the pipe line heat receiving portion 15a along the outer surface of the heat collection member.

  The heat collecting member 143 of the power supply connector 10C and the cable-equipped power supply connector 20C shown in FIG. 5 is formed in an outer cylindrical shape (see FIG. 6). The inner diameter of the heat collecting member 143 is slightly larger than the covering portion of the feed cable 21. The heat collecting member 143 is fixed to the heat conducting member 13. The heat collecting member 143 is externally inserted in the covering portion of the power feeding cable 21 and is supported and disposed so as to be separated from the power feeding cable 21 covering portion at the connector terminal 12 via the heat conducting member 13.

  The heat collecting member 143 can adopt a configuration in which the interposing member 18 is provided between the inner peripheral surface and the outer peripheral surface (side peripheral surface) of the power feeding cable 21 in that the contact of the heat collecting member 143 is more reliably avoided.

  As shown in FIG. 5, the space 14 b of the heat collecting member 143 is annularly formed inside the heat collecting member 143 in the circumferential direction of the heat collecting member 143 (direction around the central axis of the cylindrical heat collecting member 143). ing. Also, the space 14 b is in communication with the tube 32 (specifically, the fluid flow path inside the heat collecting member 143) connected to the both sides via the central axis of the heat collecting member 143. In FIGS. 5 and 6, the two tubes 32 connected to the heat collecting member 143 are indicated by reference numerals 32a and 32b for distinction. Hereinafter, the tube of code 32a is also referred to as a first tube, and the tube of code 32b is also referred to as a second tube.

The end of the tube 32 opposite to the end connected to the heat collecting member 143 is connected to the fluid circulation heat exchange device 31.
A fluid (for example, water or the like) is introduced into the space 14b of the heat collection member 143 from the fluid circulation heat exchange device 31 via the first tube 32a. The fluid in the space 14b is pushed out of the space 14b to the second tube 32b by the inflow of fluid from the first tube 32a to the space 14b. The space 14 b of the heat collecting member 143 functions as a fluid flow path for leading the fluid flowing in from the first tube 32 a connected to the heat collecting member 143 to the second tube 32 b.
Hereinafter, the space 14 b of the heat collecting member 143 is also referred to as a heat collecting member internal flow passage.

The cable-equipped power supply connector 20C shown in FIG. 5 is a circulation path (fluid flow path configured by the device internal flow path of the fluid circulation heat exchange device 31, the tubes 32a and 32b, and the heat collection member internal flow path 14b to circulate the fluid (Hereinafter also referred to as fluid circulation path). The heat collection member internal flow passage 14 b constitutes a part of a fluid circulation passage (fluid flow passage).
The fluid circulation heat exchange device 31 plays the role of circulating the fluid in the fluid circulation path and keeping the temperature of the fluid delivered from the device internal flow path to the first tube 32a at normal temperature (5 to 35 ° C.) or below normal temperature.

  The cable-equipped power supply connector 20C shown in FIG. 5 causes the fluid circulation heat exchange device 31 to circulate the fluid in the fluid circulation path, thereby suppressing the temperature rise of the heat collection member 143. As a result of suppressing the temperature rise of the heat collecting member 143, the cable-equipped power feeding connector 20 </ b> C suppresses the temperature rise of the connector terminal 12 and the heat conducting member 13 which are heated by the energization.

Hereinafter, the heat collecting member 143 in which the heat collecting member internal flow passage 14b is formed is also referred to as a flow passage forming heat collecting member.
The heat of the flow passage forming heat collecting member 143 is conveyed by the fluid flowing in the heat collecting member inner flow passage 14 b in direct contact with the inner surface thereof. Therefore, as in the first and second embodiments, the flow path forming and heat collecting member 143 is configured to carry the heat of the heat collecting member 14 by the fluid flowing inside the fluid conduit 15 along the outer surface thereof. In comparison, the heat of the heat collecting member 14 can be efficiently transported.
The feeding connector 10C and the feeding connector with cable 20C shown in FIG. 5 are advantageous for suppressing the temperature rise of the heat collecting member 14 as compared to the feeding connectors of the first and second embodiments and the feeding connector with cable.

The power supply connector is not limited to the structure which ensured the fluid flow path for preventing the temperature rise of the heat collection member 14 as illustrated in FIGS. 1-6.
For example, as shown in FIG. 7, the power supply connector may have a finned heat collecting member 144 having a flat heat collecting member 142 and a fin 14F for heat radiation protruding therefrom.
The finned heat collecting member 144 of FIG. 7 has a structure in which a plurality of fins 14F are provided on one surface of a flat heat collecting member 142. The plurality of fins 14F are provided in parallel to one another.
The fins 14F are formed in a metal plate shape integral with the metal heat collecting member 142.

  The feed connector of the cable-attached feed connector can adopt a configuration in which the finned heat collecting member 144 is accommodated in the housing 11 together with the connector terminal 12 and the heat conducting member 13 connected to the tip of the conductor 21 a of the feed cable 21. As the housing 11 of this power supply connector, in order to secure the heat dissipation from the fins 14F, one or more ventilating window holes communicating with the inside and the outside of the housing 11 are employed.

The power supply connector in which the finned heat collecting member 144 is accommodated in the housing 11 is, for example, used in an environment exposed to the wind generated by a blower such as a fan, the heat is dissipated from the fins 14F, and the heat collecting member 142 thereby. The effect of heat removal from can be easily obtained.
The discharge of heat from the heat collection member 142 by the wind is realized by the heat transferred from the heat collection member 142 to the fins 14F being transported from the fins 14F by the wind that has entered the housing 11 from the ventilation window hole. Ru.

In order to suppress an excessive temperature rise of the connector terminals 12 in the housing 11, it is necessary to smoothly discharge the air (air flow) which has received the heat from the fins 14F from the housing 11 to the outside thereof.
In this respect, the housing 11 adopts a configuration in which ventilation window holes are formed in each of the wall portions on both sides via the fins 14F to form an air flow (wind) passing through the inside. The air flow passing through the inside of the housing 11 may pass straight through the inside of the housing 11 or may meander through the inside of the housing 11. However, the air flow meandering through the housing 11 is formed so as to avoid contact with the connector terminal 12 and the heat conducting member 13 after receiving heat from the fins 14F.

The fins 14F are heat removal means for discharging the heat of the heat collection member 14 out of the housing 11 by the air flow in contact with the fins 14F.
The power supply connector in which the finned heat collecting member 144 is housed in the housing 11 can remove heat from the heat collecting member 142 only by using it in an environment exposed to the wind without using the fluid circulation heat exchange device 31 Therefore, excessive temperature rise suppression of the connector terminal 12 can also be realized.

In this fixing structure, the heat of the connector terminal 12J is not only transmitted directly from the tongue 12d to the heat collecting member 14, but also transmitted from the tongue 12d to the heat collecting member 14 via the pressing plate 14c. Further, in the configuration of FIG. 9, the heat transmitted from the connector terminal 12J to the holding plate 14c by screwing the holding plate 14c to the heat collecting member 14 using a metal set screw excellent in thermal conductivity such as stainless steel.
