Further, the shield member 50 is brought into contact with the holding member 101 (the fixed portion 101 a ) of the connector installation target 100 via the fixing portion 52 . That is, the heat is transferred also between the shield member 50 and the connector installation target 100 in this connector 1 . Thus, the heat dissipating portion 23 is also brought into contact with the shield member 50 .

Description
- The present application claims priority to and incorporates by reference the entire contents of Japanese Patent Application No. 2017-147010 filed in Japan on Jul. 28, 2017.
- The present invention relates to a connector.
- Conventionally, a female connector and a male connector which electrically connect male and female terminals, separately provided, to each other have been known as connectors. For example, the female connector includes a female terminal having a tubular terminal connection portion, and a housing accommodating the female terminal. On the other hand, the male connector includes a male terminal having a shaft-shaped terminal connection portion, and a housing accommodating the male terminal. As the housings of the female connector and the male connector are inserted and fitted to each other, the terminal connection portion of the male terminal is inserted and fitted to a space inside the terminal connection portion of the female terminal. A connector of this type is disclosed, for example, in Japanese Patent Application Laid-open No. 2016-72009 below. Here, in the connectors which have been fitted to each other, the female terminal and the male terminal generate heat as a current flows thereto, and temperatures of components including the female terminal and the male terminal rise. In particular, each amount of heat generation of the female terminal and the male terminal increases when a large current flows, and thus, there is a possibility that cost for the temperature rise of the components becomes great. For example, in the connector of Japanese Patent Application Laid-open No. 2016-72009, a male terminal is screwed to a nut, fixed to a fixing portion of a housing, and heat of the male terminal is released to the fixing portion via the nut as a heat transfer component.
- Meanwhile, the conventional connector is provided with the heat transfer component in order to release the heat of the male terminal as described above. That is, the number of components is increased in order to release the heat of the male terminal in the conventional connector. The conventional connector has room for improvement in this point of view.
- Therefore, an object of the present invention is to provide a connector capable of suppressing a temperature rise while suppressing an increase in the number of components.
- A connector according to one aspect of the present invention includes a male terminal which has an outer peripheral wall side of a tubular terminal connection portion as a contact point with a mating terminal; an insulating insulation member that achieves electrical insulation of a distal end of the terminal connection portion on a side of a mating connector; and an insulating housing which accommodates the male terminal and the insulation member, wherein the insulation member includes: a distal end insulation portion provided at the distal end of the terminal connection portion; a shaft portion extending from the distal end insulation portion along a space inside the terminal connection portion, and at least one heat dissipating portion which is a portion protruding from the shaft portion toward an outside of the terminal connection portion in a direction intersecting a cylinder axis of the terminal connection portion, and is capable of dissipating heat at the outside of the terminal connection portion.
- According to another aspect of the present invention, in the connector, it is preferable that the housing has a fixing portion which is attached to a connector installation target, and the heat dissipating portion is brought into contact with the connector installation target when the housing is attached to the connector installation target.
- According to still another aspect of the present invention, in the connector, it is preferable that the heat dissipating portion is sandwiched between the housing and the connector installation target when the housing is attached to the connector installation target.
- According to still another aspect of the present invention, in the connector, it is preferable that the heat dissipating portion is brought into contact with a portion of the connector installation target having a higher thermal conductivity than that of the insulation member.
- According to still another aspect of the present invention, it is preferable that the connector further includes a shield member which has both an electrical conductivity and a high thermal conductivity, electrically shields an inside of the housing, and is brought into contact with the connector installation target, wherein the heat dissipating portion is brought into contact with the shield member.
- The above and other objects, features, advantages and technical and industrial significance of this invention will be better understood by reading the following detailed description of presently preferred embodiments of the invention, when considered in connection with the accompanying drawings.

- One of embodiments of the connector according to the present invention will be described with reference to
FIGS. 1 to 10 . -
Reference numeral 1 inFIGS. 1 to 4 represents a connector according to the present embodiment. Theconnector 1 is attached to an object to be installed (hereinafter referred to as a “connector installation target”) 100 (FIGS. 1, 2 and 4 ). Incidentally, ahousing 30 is integrated with amale terminal 10 by insert-molding in theconnector 1 as will be described later. Therefore,FIG. 3 illustrates thehousing 30 which has been taken out from themale terminal 10 after the insert-molding for convenience of description. - The
connector installation target 100 is an object to be electrically connected to a mating connector 200 (FIGS. 1, 5 and 6 ) and examples thereof includes drive devices of a vehicle (an electric motor, an inverter, and the like of an electric car or a hybrid vehicle), electrical equipment (such as an actuator) serving as a load, and the like. Theconnector installation target 100 includes a main body (not illustrated) to be electrically connected and a holding member 101 (FIGS. 1, 2, and 4 ) that holds the main body. Theholding member 101 indicates, for example, a casing such as an accommodating member that accommodates the main body, a frame that holds and supports the main body, and the like. Themating connector 200 indicates a connector that is physically and electrically connected to theconnector 1 of the present embodiment. Themating connector 200 is electrically connected to the main body of theconnector installation target 100 via theconnector 1 of the present embodiment. - The
connector 1 is a so-called male connector and includes a male-type terminal (hereinafter referred to as a “male terminal”) 10 (FIGS. 1, 3, 4 and 7 to 9 ). As theconnector 1 is inserted and fitted to themating connector 200 which is a female connector, themale terminal 10 is physically and electrically connected to a female terminal 201 (FIGS. 5 and 6 ) which is a mating terminal. - The
male terminal 10 is molded into the mail type using a conductive material such as metal. Here, a male terminal fitting molded using a metal material such as copper, a copper alloy, aluminum, and an aluminum alloy is illustrated as an example of themale terminal 10. Themale terminal 10 includes aterminal connection portion 11, anelectrical connection portion 12, and a coupling portion 13 (FIGS. 3, 4, and 7 to 9 ). - The
terminal connection portion 11 is a portion to be physically and electrically connected to thefemale terminal 201. Theterminal connection portion 11 is formed in a tubular shape, and an outer peripheral wall side thereof is used as a contact point with aterminal connection portion 201 a (FIGS. 5 and 6 ) of thefemale terminal 201. Theterminal connection portion 201 a of thefemale terminal 201 is formed into a tubular shape so that theterminal connection portion 11 of themale terminal 10 can be inserted into an internal space thereof. Here, each of theterminal connection portions terminal connection portion 11 of themale terminal 10 is fitted to theterminal connection portion 201 a and is physically and electrically connected to theterminal connection portion 201 a by being inserted into the space at the inner side of theterminal connection portion 201 a of thefemale terminal 201. In theterminal connection portion 11 of themale terminal 10, an end on a side of the mating connector 200 (that is, an inserting direction side toward theterminal connection portion 201 a of the female terminal 201) is set as adistal end 11 a, and an end on the opposite side of the end (distal end 11 a) is set as arear end 11 b (FIGS. 3, 4 , and 7 to 9). - The
electrical connection portion 12 is a portion to be electrically connected to the main body of theconnector installation target 100. When theconnector 1 is attached to theconnector installation target 100, theelectrical connection portion 12 is arranged in an internal space of theholding member 101 as the casing, and is electrically connected to the main body in the internal space. Theelectrical connection portion 12 in this example is formed into a shape such as a so-called rectangular terminal that is physically and electrically connected to a counterpart by screwing. - The
coupling portion 13 is a portion connecting theterminal connection portion 11 and theelectrical connection portion 12. Thecoupling portion 13 is formed in a shaft shape. Thecoupling portion 13 has one end coupled with theterminal connection portion 11 and the other end coupled with theelectrical connection portion 12. Thecoupling portion 13 in this example is formed in a straight columnar shape and is arranged coaxially with a cylinder axis of theterminal connection portion 11. Therear end 11 b of theterminal connection portion 11 is connected to thecoupling portion 13. - The two
male terminals 10 are arranged side by side in the connector 1 (FIG. 3 ). - The
connector 1 further includes an insulatinginsulation member 20 configured to achieve electrical insulation of thedistal end 11 a of the terminal connection portion 11 (FIGS. 2 to 4, 7, and 10 ). Theinsulation member 20 is molded using an insulating material such as synthetic resin. Thisinsulation member 20 is provided for each of themale terminals 10. Incidentally, theinsulation member 20 is integrated with themale terminal 10 by insert-molding as will be described later. Therefore,FIG. 10 illustrates theinsulation member 20 which has been taken out from themale terminal 10 after the insert-molding for convenience of description. - The
insulation member 20 is used not only for the electrical insulation of thedistal end 11 a of theterminal connection portion 11 but also for heat dissipation of themale terminal 10 as will be described later. Accordingly, it is desirable to use a material having a high thermal conductivity among the insulating materials for theinsulation member 20. In addition, it is desirable to mold theinsulation member 20 using a material having a higher thermal conductivity than that of thehousing 30 to be described later. For example, here, PPS (Poly Phenylene Sulfide) is used for theinsulation member 20 and PBT (Polybutylene Terephthalate) is used for thehousing 30. - The
insulation member 20 has a distalend insulation portion 21 provided at thedistal end 11 a of the terminal connection portion 11 (FIGS. 2 to 4, 7, and 10 ). The distalend insulation portion 21 is a portion configured to achieve the electrical insulation of thedistal end 11 a of theterminal connection portion 11. The distalend insulation portion 21 is formed in a columnar shape and is arranged in the state of protruding from thedistal end 11 a on an end surface of thedistal end 11 a of theterminal connection portion 11. Here, the distalend insulation portion 21 is formed so as to have a columnar shape having a circular cross section orthogonal to the axial direction in accordance with the cylindricalterminal connection portion 11. - This
insulation member 20 achieves electrical insulation of thedistal end 11 a of theterminal connection portion 11 at the distalend insulation portion 21, and has not only such a function for electrical insulation but also a function for releasing heat generated by energization between themale terminal 10 and thefemale terminal 201. - When the
terminal connection portion 11 generates heat accompanying energization, themale terminal 10 transmits the heat to thecoupling portion 13 and further transmits the heat from thecoupling portion 13 to theelectrical connection portion 12. As will be described later, a side of thecoupling portion 13 facing theelectrical connection portion 12 and theelectrical connection portion 12 are arranged outside thehousing 30 in themale terminal 10. Accordingly, the heat generated in theterminal connection portion 11 is dissipated to the atmosphere of the internal space of the holdingmember 101 serving as the casing, for example, via thecoupling portion 13 and theelectrical connection portion 12. However, the amount of heat generation at theterminal connection portion 11 increases when a large current flows, and thus, it is necessary to dissipate more heat. - Therefore, the
connector 1 is configured such that the heat generated in theterminal connection portion 11 is dissipated via theinsulation member 20. Themale terminal 10 has ashaft portion 22 which serves as a heat receiving portion of the heat generated in theterminal connection portion 11 and aheat dissipating portion 23 which dissipates the heat (FIGS. 4, 7, and 10 ). - The
shaft portion 22 is a portion which extends from the distalend insulation portion 21 along aspace 11 c inside the terminal connection portion 11 (FIGS. 4, 7, and 8 ). Theshaft portion 22 is formed so as to be in close contact with an inner peripheral wall of thespace 11 c, and receives the heat of theterminal connection portion 11 from the inner peripheral wall. Here, theshaft portion 22 is formed in a columnar shape in accordance with the cylindricalterminal connection portion 11. Theshaft portion 22 extends from thedistal end 11 a to therear end 11 b of theterminal connection portion 11. - The
heat dissipating portion 23 is a portion which protrudes from theshaft portion 22 toward the outside of theterminal connection portion 11 in a direction intersecting a cylinder axis of theterminal connection portion 11. That is, theheat dissipating portion 23 can receive the heat that has transmitted through theshaft portion 22 and dissipate the heat outside theterminal connection portion 11. Theterminal connection portion 11 has a throughhole 11 d for communicating theinner space 11 c with the outside (FIGS. 8 and 9 ). Theheat dissipating portion 23 is connected between thespace 11 c inside theterminal connection portion 11 and the outside through the throughhole 11 d. - At least one
heat dissipating portion 23 is provided. For example, theheat dissipating portion 23 is formed to protrude from theshaft portion 22 in a shaft shape. Here, the two shaft-shapedheat dissipating portions 23, which protrude in a direction orthogonal to the cylinder axis of theterminal connection portion 11, are provided (FIGS. 3, 4, 7, and 10 ). The respectiveheat dissipating portions 23 protrude in directions opposite to each other at therear end 11 b of theterminal connection portion 11. - The
connector 1 further includes the insulatinghousing 30 which accommodates themale terminal 10 and the insulation member 20 (FIGS. 1 to 4 ). Thehousing 30 is molded using an insulating material such as synthetic resin. As described above, thehousing 30 is molded using PBT in this example. - The
housing 30 has a fitting portion 31 (FIGS. 1 to 4 ). Thefitting portion 31 is inserted and fitted to afitting portion 202 a (FIGS. 1, 5, and 6 ) of amating housing 202. Thefitting portion 31 is formed in a tubular shape having an elliptical cross section. Thefitting portion 202 a is formed in a tubular shape so as to serve as an inner space of the elliptical cross section into which thefitting portion 31 can be inserted. Aseal member 41, configured to improve liquid tightness, is provided between the respectivefitting portions FIG. 5 ). - Two sets of a combination of the
male terminal 10 and theinsulation member 20 are accommodated in a space inside thefitting portion 31. Thefitting portion 31 has two columnar spaces along a cylinder axis direction at an inside thereof, and the respective spaces are used as male terminal accommodating chambers 32 (FIGS. 1 to 4 ). Each one set of the combination of themale terminal 10 and theinsulation member 20 is accommodated in each of the maleterminal accommodating chambers 32. Theterminal connection portion 11 of themale terminal 10 and the distalend insulation portion 21 and theshaft portion 22 of theinsulation member 20 are accommodated in the maleterminal accommodating chamber 32 in this example. - The male
terminal accommodating chamber 32 becomes a cylindrical space in the state where themale terminal 10 and theinsulation member 20 are accommodated. When theconnector 1 and themating connector 200 are inserted and fitted to each other, a femaleterminal accommodating portion 202 b (FIGS. 5 and 6 ) of themating housing 202 is inserted into this cylindrical maleterminal accommodating chamber 32 through anopening 31 a 1 (FIGS. 1 to 4 ) at oneend 31 a of thefitting portion 31. The femaleterminal accommodating portion 202 b is formed in a cylindrical shape and accommodates thefemale terminal 201 in a space inside thereof. Accordingly, theterminal connection portion 11 of themale terminal 10 is inserted and fitted to theterminal connection portion 201 a of thefemale terminal 201 as the femaleterminal accommodating portion 202 b is inserted into the cylindrical maleterminal accommodating chamber 32. - In this manner, the
male terminal 10 is accommodated inside thefitting portion 31 in thehousing 30. Therefore, theconnector 1 has ashield member 50 which electrically shields the inside of thefitting portion 31 of the housing 30 (FIGS. 1 to 4 ). Theshield member 50 is molded into a tubular shape having an elliptical cross section using a conductive material, and is provided on thefitting portion 31 while aligning cylinder axes thereof. Here, theshield member 50 is molded using a member (a metal material or the like) having both an electrical conductivity and a high thermal conductivity. Theshield member 50 in this example has a tubular shieldmain body 51 that covers an outer peripheral wall of thefitting portion 31 from the outside (FIGS. 1 to 4 ). In addition, theshield member 50 in this example is fastened to a fixedportion 101 a (FIG. 1 ) of the holdingmember 101 together with a fixing portion 34 (FIGS. 1 to 4 ) of thehousing 30 by a screw member (not illustrated) as will be described later. Accordingly, here, theshield member 50 has a fixingportion 52 which is fixed to the fixedportion 101 a at the time of fastening together (FIG. 4 ). The fixingportion 52 is fixed in the state of being in contact with the fixedportion 101 a. That is, at least a part of theshield member 50 in this example including the fixingportion 52 is brought into contact with the holdingmember 101. - The
housing 30 has a cylindrical holdingportion 33 at an end (theother end 31 b) of thefitting portion 31 on a side opposite to theopening 31 a 1 (FIGS. 1, 3, and 4 ). The holdingportion 33 is arranged coaxially with the maleterminal accommodating chamber 32, and holds thecoupling portion 13 of themale terminal 10 in a space inside thereof. The holdingportion 33 is provided for each of themale terminals 10. A cylindricalrear holder 60 is fitted to the holding portion 33 (FIGS. 1, 3, and 4 ). Thecoupling portion 13 protrudes from therear holder 60. - The
housing 30 has the fixingportion 34 which is attached to the connector installation target 100 (FIGS. 1 to 4 ). The fixingportion 34 is a portion formed in a flange shape at theother end 31 b of thefitting portion 31. The fixingportion 34 is fixed to the fixedportion 101 a (FIG. 1 ) of theconnector installation target 100 by screwing using a screw member (not illustrated). The fixedportion 101 a is a part of the holdingmember 101. The holdingmember 101 has a throughhole 101 b (FIGS. 1 and 4 ) through which theother end 31 b of thefitting portion 31 is inserted, and a predetermined region including a peripheral edge of the throughhole 101 b is used as the fixedportion 101 a. An annular seal member 42 (FIGS. 1, 3 and 4 ) configured to improve liquid tightness is provided between theother end 31 b and the throughhole 101 b. In the state where theother end 31 b is inserted through the throughhole 101 b,flat surfaces portion 34 and the fixedportion 101 a are brought into close contact with each other (FIG. 4 ). In thisconnector 1, the fixingportion 52 of theshield member 50 is fastened in the state of being in contact with the fixedportion 101 a when screwing the fixingportion 34 and the fixedportion 101 a. - The
heat dissipating portion 23 described above is brought into contact with theconnector installation target 100 when thehousing 30 is attached to theconnector installation target 100. Theheat dissipating portion 23 is desirably sandwiched between thehousing 30 and theconnector installation target 100 in order to maintain the contact state with theconnector installation target 100. Theheat dissipating portion 23 transmits the heat received from theshaft portion 22 to theconnector installation target 100 by being brought into contact with theconnector installation target 100. Therefore, theheat dissipating portion 23 is desirably brought into contact with a portion having a higher thermal conductivity than theinsulation member 20 in theconnector installation target 100. In this example, the holdingmember 101 of theconnector installation target 100 is molded using aluminum having a higher thermal conductivity than theinsulation member 20. - Thus, the
heat dissipating portion 23 is brought into contact with the holdingmember 101. - The
heat dissipating portion 23 in this example is brought into contact with the fixedportion 101 a of the holdingmember 101. In this example, theheat dissipating portion 23 is formed so as to be flush with theflat surface 34 a of the fixingportion 34, and theheat dissipating portion 23 is brought into close contact with the fixedportion 101 a when the fixingportion 34 and the fixedportion 101 a are fixed. That is, here, theheat dissipating portion 23 is sandwiched between the fixingportion 34 and the fixedportion 101 a. - In the
connector 1 configured in this manner, themale terminal 10 and theshield member 50 is separately molded. Further, in theconnector 1, theinsulation member 20 is insert-molded in a die in which themale terminal 10 is arranged. Thereafter, in theconnector 1, thehousing 30 is insert-molded in a die in which the integrated body of themale terminal 10 and theinsulation member 20 and theshield member 50 are arranged. - Since the
connector 1 is formed by such insert-molding, themale terminal 10 and theinsulation member 20 can be brought into close contact with each other, and theinsulation member 20 can receive the heat of themale terminal 10. For example, since theshaft portion 22 can be arranged in close contact with thespace 11 c inside theterminal connection portion 11, theinsulation member 20 can receive the heat of theterminal connection portion 11 which is a heat source from the inner peripheral wall of thespace 11 c. - In addition, since the
housing 30 is also insert-molded with respect to theinsulation member 20 in theconnector 1, theheat dissipating portion 23 of theinsulation member 20 and the fixingportion 34 of thehousing 30 can be brought into close contact with each other. Accordingly, the heat can be transferred from a high-temperature side to a low-temperature side between theinsulation member 20 and thehousing 30 in thisconnector 1. For example, when the temperature of theinsulation member 20 is higher than that of thehousing 30, theheat dissipating portion 23 can dissipate the heat received from theshaft portion 22 to theconnector installation target 100, and further, dissipate the heat even to the fixingportion 34 of thehousing 30. In addition, when the temperature of theinsulation member 20 is lower than that of thehousing 30, theheat dissipating portion 23 not only receives heat from theshaft portion 22 but also receives heat from the fixingportion 34 of thehousing 30. Theheat dissipating portion 23 in this case dissipates the heat received from theshaft portion 22 and the fixingportion 34 to theconnector installation target 100. - As described above, the
connector 1 of the present embodiment can receive the heat of themale terminal 10 generated accompanying the energization and the heat of thehousing 30 generated accompanying the heat generation of themale terminal 10 using theinsulation member 20, and dissipate the received heat to the surroundings of theconnector installation target 100 and the like. Therefore, theconnector 1 can suppress the temperature rise of themale terminal 10, and accordingly, can suppress the temperature rise of thehousing 30 and inside thehousing 30. In addition, theconnector 1 of the present embodiment imparts the functions of receiving and dissipating the heat to theinsulation member 20 configured to achieve the electrical insulation of thedistal end 11 a of theterminal connection portion 11. That is, thisconnector 1 is not newly provided with a dedicated component configured to suppress the temperature rise accompanying the energization. In this manner, theconnector 1 of the present embodiment can suppress the temperature rise while suppressing the increase in the number of components. - Here, the
shield member 50 has both the electrical conductivity and the high thermal conductivity in theconnector 1 as described above. Further, theshield member 50 is brought into contact with the holding member 101 (the fixedportion 101 a) of theconnector installation target 100 via the fixingportion 52. That is, the heat is transferred also between theshield member 50 and theconnector installation target 100 in thisconnector 1. Thus, theheat dissipating portion 23 is also brought into contact with theshield member 50. For example, theheat dissipating portion 23 is brought into contact with a part of the shieldmain body 51. As a result, theheat dissipating portion 23 can transmit the heat received by itself to theshield member 50. That is, theheat dissipating portion 23 in this example can dissipate the heat received by itself to theconnector installation target 100 via theshield member 50. Therefore, theconnector 1 of the present embodiment further improves the heat dissipation property. - A connector according to the present embodiments can receive heat of a male terminal generated accompanying energization using an insulation member, and dissipate the received heat from a heat dissipating portion to the surroundings of a connector installation target or the like. Therefore, this connector can suppress the temperature rise of the male terminal, and accordingly, can also suppress a temperature rise of the housing and inside the housing. In addition, the connector according to the present embodiments imparts functions of receiving and dissipating the heat to the insulation member configured to achieve electrical insulation of a distal end of the terminal connection portion. That is, this connector is not newly provided with a dedicated component configured to suppress the temperature rise accompanying the energization. In this manner, the connector according to the present embodiments can suppress the temperature rise while suppressing an increase in the number of components.
- Although the invention has been described with respect to specific embodiments for a complete and clear disclosure, the appended claims are not to be thus limited but are to be construed as embodying all modifications and alternative constructions that may occur to one skilled in the art that fairly fall within the basic teaching herein set forth.
