  More specifically, for example, when the locking portion is made of an elastic material, when the locking portion is inserted in the fitting direction with the locked portion, the locking portion is fitted to the locked portion. It is inserted by being deformed according to the shape in the direction crossing the matching direction. In this case, when the shape in the direction intersecting with the fitting direction of the locked portion is larger along the fitting direction than the shape of the insertion position, the locking portion is elastically deformed to cause the original shape.

  The heat transfer path 2 is not particularly limited in shape as long as heat can be transferred from the heat generating body 100 to the heat radiating body 200, but the heat transfer path 2 generates heat in the engine room with little surplus space. Since it is for connecting the body 100 and the heat radiating body 200, it is preferably a thin long body.

It is comprised with the contact part 60 made to contact 200 directly.

As shown in FIG. 1, the connection main body 31 is a thin plate-like body along the contact surface of the heating element 100 and is made of a material having high thermal conductivity.
As shown in FIG. 2, the connecting portion 32 is formed on a top surface of the connection main body portion 31, and is configured by a cylindrical main body 33 that is a hollow substantially cylindrical body having one end opened.

The cylinder main body 33 is a hollow cylindrical body having an opening 34 at the end in the + Y direction. The cylinder 33 has an opening cylinder 33 a having a diameter equal to the outer diameter of the opening 34, and is slightly more than the outer diameter of the opening 34. The closed cylindrical body 33b has a small diameter and the -Y-axis side end is closed, and the open cylindrical body 33a and the closed cylindrical body 33b are integrally formed side by side in the Y-axis direction ( (See FIG. 2).

Note that the heat conducting wire crimping portion 35, which is a portion for crimping the heat conducting wire of the heat transfer path 2 in which the opening 34 is inserted, is formed on the outer peripheral surface of the cylinder forming the cylinder body 33 with a reduced outer diameter in the + Y direction. ing.

The contact portion 60 is a contact portion that comes into contact with the heating element 100 formed on the lower surface of the connection main body portion 31, and is formed so that the surface shape is along the surface shape of the heating element 100. Further, in order to improve the thermal conductivity without improving the conductivity, the surface of the contact portion 60 is covered with an insulating portion 61 formed of an insulator in which a suitable amount of carbon nanotubes are filled in a synthetic resin.
In the present embodiment, the contact portion 60 is connected to the heating element 100, but it can also be connected to the radiator 200.

  Thus, the cooling structure 1 which comprised each element couple | bonds the both ends of the heat transfer path 2 with the connection body 3 via the connection part 32, respectively, and the contact part 60 with which one connection body 3 is provided is the heat generating body 100. It can be easily attached to the heat generating body 100 and the heat dissipating body 200 at desired positions by attaching the contact portion 6 provided on the other connecting body 3 to the heat dissipating body 200. And the cooling structure 1 attached so that the heat generating body 100 and the heat radiating body 200 may be straddled, the other connection body 3 via the heat transfer path 2 the heat absorbed from the heat generating body 100 via the one connection body 3. The heat can be radiated from the heat radiating body 200 via the other connecting body 3.

  In other words, in the cooling structure 1 in which the heat generating body 100 and the heat radiating body 200 are connected by the heat transfer path 2 to release and cool the heat generated in the heat generating body 100 from the heat radiating body 200, the heat generating body 100 or the heat radiating body 200. A connection body 3 that connects the heat transfer path 2 and a contact portion 60 that contacts the surface of the heat generating body 100 or the heat dissipating body 200, and a connection section 32 that connects to the heat transfer path 2. It is possible to cool the heating element 100 by easily connecting to the heating element 100 and the radiator 200 installed at the position.

  More specifically, when the connection body 3 is brought into contact with the heating element 100, the connection body 3 can absorb heat from the heating element 100 via the contact portion 60. Further, when the connection body 3 is brought into contact with the heat radiating body 200, the connection body 3 can radiate heat to the heat radiating body 200 through the contact portion 60 in contact with the heat radiating body 200.

  Therefore, the heat generating body 100 and the heat radiating body 200 can be connected to each other through the heat transfer path 2 connected to the connecting body 3 in contact with the heat generating body 100 and the heat radiating body 200 arranged at desired positions. . Therefore, heat can be absorbed from the connecting means that is in contact with the heating element 100 disposed at a desired position, and the heat can be transferred to the emitting body via the heat transfer path 2 to be radiated.

  Furthermore, the heat transfer path 2 connected to the connection body 3 connected to the heating element 100 can be routed in a desired path in the surplus space of the engine room and connected to the heat dissipation body 200. That is, the heat transfer path 2 can be routed according to the surplus space of the engine room, and the heating element 100 and the heat dissipation body 200 can be easily connected via the heat transfer path 2 even in a narrow space. The heat can be conducted from the heating element 100 to the radiator 200.

  Moreover, the connection body 3 conducts electricity from the heating element 100 by providing the insulating part 61 having an insulating property between the contact part 60 and the connecting part 32 where the heating element 100 or the heat dissipation element 200 comes into contact. The connection body 3 can dissipate heat to the heat radiating body 200 without conducting electricity.

  If a metal wire such as copper having high heat conductivity and high conductivity at the same time is used for the heat transfer path 2, heat can be efficiently transferred. Current will flow. For this reason, there is a possibility that an unintended current flows in the heat transfer path 2 and thus it becomes impossible to supply necessary power to the control device or the like, or a magnetic field generated by an unintended current flowing in the heat transfer path 2. Noise may be generated and the electronic device may be mixed.

On the other hand, in the present invention, since the insulating portion 61 is provided between the connecting portion 32 and the portion where the contact portion 60 contacts the heating element 100 or the heat radiating body 200, the insulating portion 61 is electrically connected. This prevents the flow of current to the heat transfer path 2 connected via at least the connecting portion 32, and also prevents the generation of a magnetic field.
Therefore, the connection body 3 can absorb heat without passing electricity from the heating element 100, and similarly, the connection body 3 can dissipate heat without flowing electricity to the heat dissipation body 200.

Note that, as described above, in the cooling structure 1 configured by the heat transfer path 2 and the connection body 3, for example, the contact portion 60 may be a cooling structure 1a configured as follows.

  The connection body 3 of the cooling structure 1a having such a configuration is fitted to the fitted portion 21 by assembling the connection body 3 from above the heating element side fitting body 20 (see FIG. 3B). The piece 63 is fitted and the connection body 3 and the heat generating body 100 can be reliably brought into contact with each other.

  Further, by making the lower surface of the connection main body 31 and the upper surface of the heating element side fitting body 20 uneven, the contact area between the connection element 3 and the heating element 100 is increased, and the heating element 100 efficiently heats the connection element 3. Can communicate.

  The cooling structure 1 a configured as described above has the same effect as the cooling structure 1 described above, and is fitted to the contact fitting 60 and the connected fitting portion 21 formed on the heating element 100 or the radiator 200.

More specifically, the connected portion 20 provided on the surface of the heating element 100 includes a groove portion 22 and an upward plate-like body 23, and the groove portion 22 has a recess provided inside the heating element-side fitting body 20. Opening to be formed. The upward plate-like body 23 is a plate-like protrusion that protrudes upward (+ Z direction) from the bottom surface of the groove portion 22 in the X-axis direction, and the end portion in the + Y direction is the inner peripheral surface of the groove portion 22. It touches. In addition, the height of the upward plate-like body 23 is slightly lower than the height of the groove portion 22 that forms the groove (see FIG. 5B).
Thus, the groove part formed by the groove part 22 and the upward plate-like body 23, and the groove part formed between each upward plate-like body 23 are connected fitting parts fitted to the fitting piece 63 described later. 21 is constituted.

The fitting piece 63 of the present embodiment is configured by a both-ends downward plate-like body 63a and a downward plate-like body 63b, which are plate-like bodies protruding downward from the lower surface of the connection main body 31.
The both end downward plate-like bodies 63 a are plate-like bodies formed on both ends of the fitting piece 63 projecting downward from the lower surface of the connection main body portion 31 in the X-axis direction, and have a height equal to the height of the groove portion 22. And a width equal to the distance from the inner wall of the groove portion 22 in the X-axis direction to the surface of the upward plate-like body 23 facing the inner wall.

  Further, the length in the longitudinal direction (Y-axis direction) of the both end downward plate-like bodies 63a is formed to be substantially the same as the length of the groove portion formed by the groove portion 22 in the Y-axis direction. Note that both end downward plate-like bodies 63a are configured to cover the surface with an insulating portion 61 which is an insulator (not shown).

  On the other hand, the downward plate-like body 63b is a plate-like body that is formed slightly lower than the both-ends downward plate-like body 63a and has a width shorter than the vertical distance between the surfaces of the opposing upward plate-like bodies 23. Yes (see FIG. 5B), the length of the upward plate-like body 23 is substantially the same.

  By assembling the connection body 3 configured in this way to the heating element side fitting body 20 from above, the upward plate-like body 23 and the groove portion 22 in which the both-end downward plate-like bodies 63a are formed at both ends in the −X-axis direction are formed. While fitting to the to-be-connected fitting part 21 to be formed, the downward plate-like body 63b enters the to-be-connected fitting part 21 which is a groove portion formed between the respective upward plate-like bodies 23 ( (See FIG. 5 (a)). At this time, the end portions of the both-end downward plate-like body 63 a and the downward plate-like body 63 b are in contact with the side surface on the −Y side of the upward plate-like body 23.

  Further, in the cooling structure 1b configured as described above, the connected fitting portion 21 formed by the groove portion 22 and the upward plate-like body 23 by assembling the connecting body 3 and the heating element side fitting body 20; Both end downward plate-like bodies 63a are fitted and securely fixed, and both end downward plate-like bodies 63a and the upper plate-like body 23 are in contact with each other, so that heat can be exchanged efficiently.

  Furthermore, in the present embodiment, the side surface of the downward plate-like body 63b and the side surface of the upward plate-like body 23 are not in contact with each other, but the groove portion formed by the groove portion 22 does not have electrical conductivity and heat By filling the thermal conductive grease 24 having excellent conductivity, the downward plate-like body 63b and the upward plate-like body 23 are indirectly contacted via the thermal conductive grease 24, and the thermal conductive grease 24 is more efficient. (See FIGS. 5A and 5B).

  In this embodiment, the heat conductive grease 24 is filled so as to fill the space between the upward plate-like body 23 and the downward plate-like body 63b. Alternatively, a sheet having a high heat exchange property such as a sheet or a belt such as a thermal sheet may be sandwiched between the upward plate 23 and the downward plate 63b.

  Moreover, when it is set as the gel form like the heat conductive grease 24, since the heat conductive grease 24 will be filled when the connection body 3 and the heat generating body side fitting body 20 are assembled | attached, upward plate shape The amount of contact area between the body 23 and the downward plate-like body 63b increases, and heat can be exchanged more efficiently.

The cooling structure 1b configured as described above has the same effects as the cooling structure 1 and the cooling structure 1a described above, and has heat transfer properties between the upward plate-like body 23 and the downward plate-like body 63b. Since the heat conductive grease 24 is provided, the adhesion between the upward plate-like body 23 and the downward plate-like body 63b can be improved, so that heat can be transmitted efficiently. Further, for example, by using the heat conductive grease 24 having a high heat conductivity between the downward plate-like body 63b and the upward plate-like body 23, it is possible to efficiently promote the movement of heat. Furthermore, since it is possible to use an insulating member as the heat conductive grease 24, only heat can be transmitted to the connection body 3 without conducting electricity.
In the present embodiment, the upward plate-like body 23 and the downward plate-like body 63b are configured not to be in direct contact with each other, but are not limited thereto, and may be configured to be in direct contact.

Next, based on FIG.6 and FIG.7, the cooling structure 1c which is other embodiment is demonstrated.
Similarly to the above, among the configurations of the cooling structure 1c described below, the same configurations as those of the above-described cooling structures 1 and 1a are denoted by the same reference numerals and description thereof is omitted.

  6 and 7, the vertical direction is the Z-axis direction, and the direction in which the boss projection 65 is inserted into the engagement hole 25 is the Y-axis direction. The direction orthogonal to the −Y axis and the Z axis is taken as the X axis direction. In addition, the insertion direction of the protrusion type | mold protrusion 65 is set to -Y direction (front), and a reverse direction is set to + Y direction (back).

  Like the cooling structures 1 and 1b, the cooling structure 1c is composed of the heat transfer path 2 and the connection body 3, and the connection body 3 faces the heating element side fitting body 20 as shown in FIGS. On the side surface of the connecting main body portion 31, there is provided a protruding projection 65 that protrudes in the −Y-axis direction. On the other hand, on the surface of the heating element side fitting body 20 facing the connecting body 3, an engagement hole 25 into which the gibbous protrusion 65 can be inserted is provided at a position facing the protrusion 65.

More specifically, the burrow type protrusion 65 is a burrow-shaped cylindrical body made of an elastic body, and includes a columnar body 65a having a rear portion embedded in the connection main body 31 and a front (−Y axis) of the columnar body 65a. An ellipse having a diameter larger than the diameter of the circle forming the bottom surface of the cylindrical body 65a with respect to the X-axis direction and the Z-axis direction, and smaller than the diameter of the circle with respect to the Y-axis direction. A sphere 65b is provided. The diameters in the X axis direction and the Z axis direction are equal. That is, the elliptical sphere 65b is an elliptical sphere that becomes a perfect circle when observed from the -Y direction.
In addition, the rear side of the cylindrical body 65a is connected to a heat induction portion 36 formed inside the connecting portion 32 provided on the surface formed in the + Y direction of the connecting body 3 (see FIG. 7).

On the other hand, the engagement hole 25 is configured by an insertion port 25a, an insertion port 25b, and a housing portion 25c.
The insertion port 25a is an insertion port formed on the surface of the heating element side fitting body 20 and having a diameter longer than the diameter corresponding to the X-axis direction of the elliptical sphere 65b. The insertion port 25b extends from the insertion port 25a. It is a circular insertion port formed inside the front side of the heating element side fitting body 20 and having a diameter slightly shorter than the diameter of the elliptic sphere 65b in the X-axis direction.

The accommodating part 25c is an accommodating part which forms the protrusion accommodating space S which has a magnitude | size substantially equal to the outer diameter of the elliptical sphere 65b inside the insertion port 25b, as shown in FIG.
The insertion port 25a and the insertion port 25b are formed in a tapered shape. In other words, the engagement hole 25 has an insertion port with a reduced diameter on the side surface in the −Y direction of the heating element-side fitting body 20, and is inserted into the heating element-side fitting body 20 by the insertion port 25 b and the accommodating portion 25 c. A protrusion accommodating space S is formed in which the part is open.

  The connection body 3 including the protrusion type protrusion 65 formed in this manner reliably generates heat by inserting the protrusion type protrusion 65 into the engagement hole 25 formed in the heating element side fitting body 20. The body 100 can be brought into contact.

  More specifically, the inner diameter of the insertion port 25a is larger than the corresponding outer diameter of the elliptical sphere 65b, and the insertion port 25a and the insertion port 25b are formed in a tapered shape. By moving in the −Y-axis direction, the elliptic sphere 65b can be guided to the insertion port 25b.

  Here, the inner diameter of the insertion port 25b is smaller than the outer diameter of the elliptical sphere 65b with respect to the X-axis and the Z-axis, but the elliptical sphere 65b is formed of an elastic material. , The elliptical sphere 65b is deformed, and the elliptical sphere 65b can be inserted into the protrusion accommodating space S (see FIG. 7B).

  Here, since the protrusion accommodating space S formed by the accommodating portion 25c is a space having substantially the same size as the elliptical sphere 65b, the rear portion of the elliptical sphere 65b (the front end of the cylindrical body 65a) is the insertion port. When passing through 25b, the elliptical sphere 65b is elastically deformed and returns to its original shape (see FIG. 7C).

  As a result, it is possible to insert the projection type protrusion 65 into the heating element-side fitting body 20, and the elliptical sphere 65 b is elastically deformed, whereby the elliptical sphere 65 b is engaged with the accommodating portion 25 c, and the connection body 3 and the heating element 100. Are fixed more securely. That is, the elliptical sphere 65b and the accommodating portion 25c are engaged in a direction intersecting with the fitting direction of the elliptical sphere 65b. Further, since the bulge-shaped protrusion 65 is formed of an elastic material, when the bulge-shaped protrusion 65 is inserted into the protrusion housing space S, the elliptical sphere 65b is elastically deformed to return to the original shape, and the elliptical sphere 65b. And the accommodating portion 25c are in close contact with each other.

  Therefore, since the contact area where the connection body 3 contacts the heating element 100 increases, the connection body 3 can efficiently absorb heat from the heating element 100. In addition, since the boss projection 65 is connected to the heat induction part 36 inside the connection main body part 31, the absorbed heat can be transmitted to the heat transfer path 2 connected to the connection part 32.

  The cooling structure 1 c configured as described above has the same effect as the cooling structure 1 described above, and the connection fitting portion 62 is fitted into the engagement hole 25 constituting the connected fitting portion 21. Since the contact portion 60 and the heating element 100 and the like can be locked in the direction intersecting the fitting direction by being configured by the convex protrusion 65 that is locked in the direction intersecting with the mating direction, the heating element 100 or the heat dissipation. The body 200 and the connection body 3 can be reliably connected.

  In addition, by forming the boss projection 65 with an elastic material, the heating element 100 or the radiator 200 including the engagement hole 25 and the connection body 3 including the boss projection 65 are more reliably and firmly connected. In addition, heat exchange between the heating element 100 or the radiator 200 and the connection body 3 can be performed more efficiently.

  More specifically, by using the bulge-shaped projection 65 as an elastic material, when the burrow-shaped projection 65 is inserted in the engagement direction with the engagement hole 25, the projection-type projection 65 is fitted into the engagement hole 25. It is inserted by being deformed according to the shape in the direction intersecting the direction. In this case, when the shape in the direction intersecting with the fitting direction of the engagement hole 25 is increased along the fitting direction as compared with the shape of the insertion position, the original projection 65 is elastically deformed to cause the original shape. Try to return to shape. As a result, the boss projection 65 is engaged with the engagement hole 25.

For this reason, the heat generating body 100 or the heat radiating body 200 including the engagement hole 25 and the connection body 3 including the bulge-shaped protrusion 65 can be more reliably and firmly connected.
Further, the elastic deformation of the convex projection 65 causes the convex projection 65 and the engaged portion to be in close contact with each other. Therefore, the contact area increases and the heat conduction becomes more efficient.

  Next, as another embodiment, as shown in FIGS. 8 and 9, from a housing 70 including a heat conduction terminal 80 in which the connection body 3 is formed in a terminal shape and a cavity 71 that can accommodate the heat conduction terminal 80. The configured connection body 3d will be described.

Hereinafter, the connection body 3d will be described with reference to FIGS.
Similarly to the above, among the configurations of the cooling structure 1d described below, the same configurations as those of the cooling structure 1 in the above-described embodiment are denoted by the same reference numerals and the description thereof is omitted.

  8 to 11, the vertical direction in the drawings is the Z-axis direction, and the direction in which the heat conduction terminal 80 is inserted into the housing opening 27 is the Y-axis direction. A direction perpendicular to both the −Y axis direction and the Z axis direction is taken as an X axis direction. Further, the upper side is the + Z direction, the lower side is the -Z direction, the direction in which the above-described heat conduction terminal 80 is inserted into the housing opening 27 is the -Y direction or the front direction, and the above-mentioned heat conduction terminal 80 is the housing opening 27. The direction opposite to the insertion direction is the + Y direction or the backward direction. In the drawing, the left side is the + X direction or the left direction, and the right side is the -X direction or the right direction.

  In the cooling structure 1d, the heating element-side fitting body 20 formed on the surface of the heating element 100 is inserted into the housing opening 27, the plurality of male terminals 28 provided in the housing opening 27, and the housing 70. And a fixing lever 29 for fixing the housing 70.

  The housing opening 27 is an opening provided on the back surface of the heating element-side fitting body 20 and has a housing accommodation space H having a size substantially equal to the outer shape of the heat conduction terminal 80 that can accommodate a heat conduction terminal 80 described later. Are openings formed in the heating element side fitting body 20.

  The male terminal 28 is a male crimp terminal that can be inserted into a heat transfer box portion 82 of a heat conduction terminal 80 formed in a terminal shape to be described later. The male terminal 28 includes a heat conduction male terminal 28a, which is a heat conduction terminal, and a conduction male terminal 28b, which is a conduction terminal. Etc. (not shown).

  The fixing lever 29 is a lever formed over the upper surface and the lower surface of the heating element-side fitting body 20. After the housing 70 is inserted into the housing housing space H, the fixing lever 29 formed in the −X direction is used. The connection of the housing 70 can be fixed by pushing the clamping portion 29a forward.

As described above, the connection body 3d includes the heat conduction terminal 80 formed in a terminal shape and the housing 70 including the cavity 71 that allows the insertion of the terminal.
The housing 70 is a housing that can be housed in a housing housing space H formed by the male terminal 28, and has six cavities 71 (two in the vertical direction and two in the horizontal direction) that are through holes penetrating in the −Y-axis direction. 3) formed. The cavity 71 includes a thermal terminal cavity 71a capable of accommodating a thermal conduction terminal 80, which will be described later, and a conductive terminal cavity 71b capable of accommodating a conductive crimp terminal 90. The thermal terminal cavity 71a is one of the six cavities 71. The conductive terminal cavities 71 b are two cavities 71 formed in the middle of the housing 70.

  As shown in FIG. 9, the heat conduction terminal 80 includes a heat transfer path connection portion 81 and a heat terminal box portion 82 arranged in this order from the rear, and is configured integrally with a connecting portion. The heat transfer path connection portion 81 and the heat transfer box portion 82 are molded on the inner surface side by an insulating portion 61 made of silicon or the like that is easily processed.

  The heat transfer path connection part 81 is a connection part for connecting the heat transfer path 2 opened in a U-shape, and is composed of a coated crimping part 81a and a heat conduction wire crimping part 81b. The covering crimping part 81a and the heat conducting wire crimping part 81b are arranged side by side from the rear, and the covering crimping part 81a located at the rear is a crimping part that crimps the outer peripheral surface of the heat transfer path 2. The heat conducting wire crimping portion 81b located in the front is a crimping portion that crimps and connects the heat conducting wire exposed by peeling off the insulating coating of the heat transfer path 2 and the insulating coating on the tip side.

  As shown in FIG. 9, the heat transfer box portion 82 is a hollow casing whose longitudinal direction is the −Y axis direction, and the heat transfer box portion 82 is disposed below the inner surface of the heat transfer box portion 82. An engaging piece for fixing the connection with the male terminal 28a for heat conduction when the male terminal 28a for heat conduction is inserted into 82 (not shown). Further, there is a through hole on the left side surface of the heat transfer box portion 82.

  The conductive crimping terminal 90 is composed of a wire crimping part 91 for inserting and crimping a coated electric wire 2b having conductivity, and a conductive box part 92 made of a housing into which the male male terminal 28b can be inserted. It is. The covered electric wire 2b is formed by covering a conductive wire with an insulating coating that is an insulator.

  In the present embodiment, the shape of the terminal to be inserted into the housing 70 is formed in the shape of a female crimp terminal. However, the shape is not limited to this, and for example, the shape of a male crimp terminal may be used. It is good also as a shape of a pin type crimp terminal. That is, when connecting the connection body 3d to the heating element 100, any shape may be used as long as the male terminal 28, the heat conductive terminal 80, and the conductive crimp terminal 90 can be connected to each other.

A method of connecting the connection body 3d having such a configuration to the heating element 100 will be described below.
First, the insulation coating covering the tip side of the heat transfer path 2 is peeled to expose the heat conducting wire, and the heat conductor wire and the insulation coating are respectively disposed on the heat conduction wire crimping portion 81b and the coating crimping portion 81a. And while crimping | bonding the crimping | compression-bonding parts 81a and 81b from the left-right direction, the heat transfer path 2 and the heat conductive terminal 80 are connected by crimping from the up-down direction (refer FIG. 9).

  Similarly, the insulated wire 2b is also stripped of the insulating coating on the tip side to expose the internal conductor, and the conductor is disposed on the wire crimping portion 91, and is crimped from the left and right directions and the up and down direction, and the coated wire 2b and the conductive crimp terminal 90 are connected. Connect (see FIG. 9).

  Next, the heat conduction terminal 80 is inserted into the heat terminal cavity 71a so that the heat transfer box portion 82 is in front, and the conductive terminal cavity 71b is in conductive contact pressure bonding so that the conductive box portion 92 is in front. Terminal 90 is inserted. At this time, the heat transfer path 2 and the covered electric wire 2b to which the heat conductive terminal 80 and the conductive crimp terminal 90 are connected are bundled with a binding band (not shown) (see FIG. 8A).

Then, the connection body 3 d constituted by the housing 70 and the heat conduction terminal 80 is connected to the heating element side fitting body 20.
Specifically, by inserting the housing 70 equipped with the heat conduction terminal 80 and the conductive crimp terminal 90 into the housing accommodating space H formed in the heating element side fitting body 20, the male terminal 28a for heat conduction provided in the housing 70 is provided. The conductive male terminal 28b can be inserted into the conductive box portion 92 of the conductive crimp terminal 90 connected to the heat transfer box portion 82 and inserted into the conductive terminal cavity 71b.

  The connection body 3d configured in this way has a structure in which the heat conduction terminal 80 and the conductive crimp terminal 90 are securely connected in advance to the housing 70, and a structure in which the male terminal 28 is connected to the heating element side fitting body 20. It has become. Therefore, the housing 70 is inserted into the housing housing space H, which is the internal space of the heating element side fitting body 20 formed on the surface of the heating element 100, and the fixing lever 29 is pushed in the + Y direction, whereby heat conduction with the male terminal 28 is achieved. The terminal 80 and the conductive crimp terminal 90 can be reliably and collectively connected.

  Further, since the inside of the heat conduction terminal 80 is molded by the insulating portion 61 that is an insulator, even if the front of the male terminal 28 is connected by a conductive metal wire or the like, The insulating portion 61 is sandwiched between the heat transfer box portion 82 and the male terminal 28, so that no current flows through the heat transfer path 2 and the like behind the heat transfer box portion 82, and noise is generated. Can eliminate the danger of doing.

  Further, the heat conduction terminal 80 for transferring heat to the housing 70 and the conductive crimp terminal 90 for flowing electricity can be accommodated, so that the heat transfer path 2 and the heat transfer path connection portion 81 are connected to the cavity 71. And the covered electric wire 2b connected to each other can be bundled with a binding band or the like and handled as a unit. Thereby, the heat transfer path 2 and the covered electric wire 2b can be handled collectively, and the wiring path of the covered electric wire 2b can be used as the wiring path of the heat transfer path 2. Therefore, it is possible to reduce the process of examining the routing path of the heat transfer path 2.

  Furthermore, since the conventional terminal and the heat conduction terminal 80 have the same shape, it is possible to use the conventional crimp terminal and housing, so it is necessary to newly produce dedicated parts and the like. Can be eliminated. Therefore, the process concerning production can be reduced, and the cost can be reduced.

The cooling structure 1d configured as described above has the same effect as the cooling structure 1 described above, and also includes a heat conduction terminal 80 in which the contact portion 60 and the connection portion 32 are formed in an integral terminal shape, By including the housing 70 having the thermal terminal cavity 71 a that houses the conductive terminal 80, the thermal conductive terminal 80 can be reliably inserted into the housing 70.
Further, by the cooling structure 1 using the housing 70, the heat conduction terminal 80 accommodated in the housing 70 can be reliably brought into contact with the heat generating body 100 or the heat radiating body 200.

More specifically, as described above, the housing 70 that forms the plurality of cavities 71 that accommodate the plurality of heat conducting terminals 80 is the female housing 70, and the female housing 70 is formed so as to be able to contact the contact portion 60 in advance. The heat generating body 100 is brought into contact with the plurality of contact portions 60 housed in the female housing 70 by being inserted into the heat generating body-side fitting body 20 serving as a male housing for housing a plurality of contacted parts provided in the heat generating body 100. The part can be reliably contacted.
As a result, as described above, it is possible to reliably contact the heating element side fitting body 20 constituting the housing provided in the heating element 100 corresponding to the housing 70 in which the heat conduction terminal 80 is previously stored.

  Further, the housing 70 is further provided with a plurality of conductive terminal cavities 71b into which the conductive crimp terminals 90 connected to the covered electric wires 2b are inserted, whereby the heat transfer path 2 connected to the heating element 100 and the covered electric wires 2b are bundled. Since it can be made into the shape extended from the housing 70 as integral, the wiring used for the heat transfer path 2 can use the wiring of the covered electric wire 2b. Therefore, the man-hour used for the wiring of the covered electric wire 2b can be reduced.

  More specifically, the heating element 100 that generates heat when executing processing necessary for a device such as a driving support device performs the transmission / reception of an electrical signal with a junction box or another electronic device. It is connected.

  Here, as described above, the housing 70 is a female having a cavity 71 for housing the heat conduction terminal 80 and a plurality of cavities 71 for inserting the conductive crimp terminals 90 connected to the covered electric wire 2b connected to the junction box. A mold housing 70 is used.

  Also, a covered electric wire 2b connected to an electronic component of the heating element 100, a conductive male terminal 28b that can be connected to the conductive crimp terminal 90, and a male terminal for heat conduction formed so as to be in contact with the contact portion 60. The heating element side fitting body 20 constituting a housing capable of accommodating 28a is provided in the heating element 100 as a male housing. In this case, by connecting the female housing 70 and the heating element side fitting body 20 which is a male housing, the electronic component and the junction box are securely connected, and the heating element 100 and the contact portion 60 are securely connected. Can be connected.

  Thus, in the cooling structure 1 that connects the heat generating body 100 and the heat radiating body 200 with the heat transfer path 2, the covered electric wire connected to the heat transfer path 2 and the conductive crimp terminal 90 from the connection body 3 connected to the heat generating body 100. Since it is set as the structure extended similarly to 2b, these can be wired together. For this reason, the routing path of the heat transfer path 2 is used as the routing path of the covered electric wire 2b, and there is no need to route a new path for the covered electric wire 2b. Therefore, the man-hour for routing the path | route for the new covered electric wire 2b can be reduced.

  Further, by using a conventionally used crimp terminal or housing as the housing 70, it is not necessary to make a new crimp terminal, and it is possible to provide a highly versatile connector 3.

In the correspondence between the configuration of the present invention and the above-described embodiment, the mated piece corresponds to the upward plate-like body 23, the heat conductive material corresponds to the heat conductive grease 24, and the locked portion engages. Corresponding to the hole 25, the contact means corresponds to the contact portion 60, the fitting portion corresponds to the connection fitting portion 62, the locking portion corresponds to the convex projection 65, and the heat transfer terminal is the heat conduction terminal 80. The terminal corresponds to the conductive crimp terminal 90, but the present invention is not limited to the configuration of the above-described embodiment, and many embodiments can be obtained.

  For example, the contact portion 60 or the like is made of an insulator that has improved thermal conductivity without improving conductivity, but is not limited to this form, for example, a metal having high conductivity. You may comprise, and you may comprise with the material with low heat conductivity. However, by using the cooling structure 1 using such a material, only heat can be transmitted to the heat transfer path 2 without current flowing from the heating element 100 to the heat transfer path 2.

  Further, in the embodiment, the insulator having improved thermal conductivity without improving conductivity is configured to be formed on the surface in contact with the heating element 100, but is not limited to this configuration. For example, The heat induction part 36 may be made of such a material, or inside the connection main body 31 such as an XY plane at a position where the height of the connection main body 31 is the middle, It is good also as a structure arrange | positioned in a transmission path | route when heat transfers from 100 to the connection part 32. FIG.

  Further, the connection body 3 connected to the heating element 100 and the heat dissipation body 200 is not necessarily the same connection body 3. For example, the connection body 3 d is connected to the heating element 100 and the connection body 3 a is connected to the heat dissipation body 200. For example, the shape of the heating element 100 and the radiator 200 can be changed as appropriate.

In addition, you may comprise the heat transfer path 2 in the above-mentioned description with the multilayer heat transfer path 40 shown in FIG. The multilayer heat transfer path 40 includes a first heat conductor 41, an inner insulator 42, a second heat conductor 43, and an outer insulating coating 44.
The first heat conductor 41 is a copper conductor having a high thermal conductivity, and has a substantially semicircular cross section that protrudes downward. The first heat conductor 41 extends along the heat transfer path 2 from the one end side (+ X direction in the drawing) to the other end side (−X direction in the drawing). The first heat conductor 41 does not penetrate the other end side of the heat transfer path 2.

  The inner insulator 42 is disposed so as to be sandwiched between the first heat conductor 41 described above and a second heat conductor 43 described later at the center in the height direction of the multilayer heat transfer path 40 having a circular cross section, and has a dielectric constant. The heat transfer path 2 is penetrated from one end side to the other end side.

  The second heat conductor 43 is a copper conductor having a high thermal conductivity, and has a substantially semicircular cross section that protrudes upward. The second heat conductor 43 is not exposed at one end of the heat transfer path 2 but is exposed at the other end of the heat transfer path 2.

  The first heat conductor 41 and the second heat conductor 43 are not limited to copper, and may be made of conductive metal, fiber reinforced plastic, pitch-based carbon fiber, or the like. The heat conductor 43 may be made of the same material, or may be made of a different material.

  The first heat conductor 41, the inner insulator 42, and the second heat conductor 43 configured in this manner are stacked in the vertical direction to form a circular cross section, and the outer insulating coating 44 made of polyethylene resin as an insulator. The multilayer heat transfer path 40 is configured by covering the entire outer periphery.

  When the multilayer heat transfer path 40 having the above configuration is used as the heat transfer path 2, the first heat conductor 41 exposed on one end side of the multilayer heat transfer path 40 is connected to the connection portion 32 of the connection body 3 attached to the heating element 100. The second heat conductor 43 exposed on the other end side of the multilayer heat transfer path 40 is connected to the connecting portion 32 of the connecting body 3 attached to the heat radiating body 200, thereby providing the same effect as that of the cooling structure 1 described above. be able to.

  More specifically, the first heat conductor 41 connected to the connection body 3 attached to the heating element 100 transfers the heat absorbed through the connection body 3 toward the other end side. In the multilayer heat transfer path 40, the entire length of the first heat conductor 41 is transferred to the second heat conductor 43 via the internal insulator 42. The second heat conductor 43 transferred from the first heat conductor 41 via the internal insulator 42 transfers heat to the heat sink 200 via the connection body 3 attached to the heat sink 200 and radiates heat from the heat sink 200. can do.

  Furthermore, the cooling structure 1 using the multilayer heat transfer path 40 as the heat transfer path 2 may be connected to an electric supply source on one end side of the heat transfer path 2 and connected to an electric circuit on the other end side, for example. Since the 1st heat conductor 41 which is the conducting wire which flows electricity does not extend to the other end side, it cannot connect with an electric circuit, and it does not supply with electricity to the 1st heat conductor 41. Similarly, since the second heat conductor 43 does not extend to one end side, the second heat conductor 43 cannot be connected to the electric power supply source, and the second heat conductor 43 is not energized. Moreover, since the internal insulator 42 which is an insulator is disposed between the first heat conductor 41 and the second heat conductor 43, the first heat conductor 41 and the second heat conductor 43 are electrically connected, Even when the heat transfer path 2 is directly connected to a circuit or the like incorporating a heating element, there is no fear of energization, and the first heat conductor 41 and the second heat conductor 43 in the multilayer heat transfer path 40 are energized. There is no adverse effect caused by noise.

  Furthermore, the structure of the multilayer heat transfer path 40 is not limited to the configuration shown in FIG. 10. For example, as shown in FIG. 11, the first heat conductor 41 in the multilayer heat transfer path 40 has a linear first shape. The first heat conducting wire 41a is arranged at the center, the first heat conducting wire 41a is covered with the inner insulator 42, the outer peripheral surface thereof is covered with the second heat conductor 43, and the outer side thereof is covered with the outer insulating coating 44. Multiple heat transfer paths 40a may be configured.

  By adopting such a configuration, heat transmitted radially from the first heat conducting wire 41a to the internal insulator 42 can be efficiently recovered by the second heat conductor 43 covering the outer peripheral surface of the internal insulator 42, More efficient heat transfer can be performed.

  In addition, when using the above-mentioned multilayer heat transfer path 40 or the multiple heat transfer path 40a as the heat transfer path 2, since the multilayer heat transfer path 40 or the multiple heat transfer path 40a itself has an insulating property, contact in the connection body 3 is possible. The connecting body 3 may be used in which the insulating portion 61 is not formed in the portion 60, that is, the insulating member 61 is not provided.
