[0007] 1. Technical issues to be resolved

[0008] Regarding the above-mentioned terminal, an inlet and an outlet for the refrigerant flow path are opened on the side of the terminal body. A cooling pipe is connected to the inlet and the outlet. However, the cooling pipe will vibrate, twist, and stretch due to the plugging and unplugging of the terminal. This may cause a load to act on the connection between the terminal and the cooling pipe, causing refrigerant leakage.

[0009] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a power supply connector with a cable that can reduce the load acting on the connection portion between the terminal and the cooling pipe.

[0010] (II) Technical solution

[0011] A power supply connector with a cable according to one embodiment of the present invention comprises: a terminal; a cooling pipe connected to the terminal, supplying a refrigerant to the terminal and having flexibility; and a retainer having a terminal holding portion for holding the terminal and a pipe holding portion for holding the cooling pipe.

[0012] According to this structure, the retainer holds both the terminal and the cooling tube, so that the cooling tube follows the movement of the terminal and the positional relationship between the terminal and the cooling tube is kept constant, thereby reducing the load acting on the connection portion between the terminal and the cooling tube. Thus, leakage of refrigerant from the connection portion between the terminal and the cooling tube can be prevented.

[0013] Regarding the above-mentioned power supply connector with a cable, the retainer may be an assembly consisting of a first split body having a split surface and a second split body opposite to the first split body via the split surface, and the position of the split surface overlaps with the terminal holding portion and the tube holding portion when viewed from the direction in which the terminal holding portion and the tube holding portion are arranged.

[0014] According to this structure, the retainer can be easily assembled with respect to the terminal and the cooling pipe.

[0015] In the above-mentioned power supply connector with cable, the tube gripping portion may include a linear portion extending parallel to a central axis of the terminal.

[0016] According to this structure, the cooling pipe can be arranged so that the rail of the cooling pipe does not expand relative to the terminal, and it is also easy to fit into a narrow space such as the inside of the housing of the power supply connector.

[0017] In the above-mentioned power supply connector with a cable, the tube gripping portion may include a bent portion bent along the cooling tube.

[0018] According to this configuration, the cooling pipe can be gripped at a position close to the connection portion between the cooling pipe and the terminal without strongly bending the cooling pipe, thereby reducing the load acting on the cooling pipe.

[0019] Regarding the power supply connector with a cable, the cooling pipe may be bent at a position rearward of the pipe gripping portion, and a curvature of the bent portion may be smaller than a curvature of the cooling pipe at a position rearward of the pipe gripping portion.

[0020] According to this configuration, a load is unlikely to be generated at a connection portion between the terminal and the cooling pipe, and refrigerant leakage can be prevented.

[0021] The power supply connector with a cable may include an anti-slip member interposed between the tube gripping portion and the cooling tube.

[0022] According to this structure, the cooling pipe can be firmly grasped by the pipe grasping portion via the anti-slip member. In addition, the cooling pipe is not easily twisted, etc.

[0023] In the above-mentioned power supply connector with a cable, the terminal may have a narrowed portion in the middle, and the retainer may have a fitting portion that fits with the narrowed portion in the middle.

[0024] According to this structure, the retainer cannot be pulled out in the axial direction relative to the terminal, and the fitting between the terminal and the retainer can be strengthened.

[0025] (III) Beneficial effects

[0026] According to one aspect of the present invention described above, it is possible to reduce the load acting on the connection portion between the terminal and the cooling pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 2 It is a perspective view showing a terminal to which a retainer according to one embodiment is assembled.

[0031] An embodiment of the present invention will be described below with reference to the drawings.

[0032] Figure 1 1 is a schematic diagram showing a power supply connector 100 with a cable according to an embodiment.

[0033] like Figure 1 As shown, the power supply connector 100 with a cable is composed of a terminal 1, a cable 105, and a housing 200. The terminal 1 and the cable 105 are connected to each other and introduced into the interior of the housing 200, and the housing 200 can be inserted into the charging port (insertion part) of the electric vehicle. The cable 105 has built-in: a conductor wire 102 for supplying power to the power supply object, and a cooling pipe 101 for cooling the conductor wire 102. The cooling pipe 101 is a pipe connected to the terminal 1, which is flexible and can be bent freely.

[0034] For the cable 105, for example, a cable having the same structure as the power supply cable described in Japanese Patent Gazette No. 6078198 can be used. Specifically, the cable 105 has a plurality of (an even number of) power lines 103 built in, and a cooling tube 101 and a conductor wire 102 are built in the power line 103. Inside the power line 103, a plurality of conductor wires 102 are collectively twisted around the cooling tube 101. Thus, the refrigerant liquid flowing in the cooling tube 101 can be used to suppress the heating of the conductor wire 102 caused by the energization. A signal line for communication between the power supply device and the electric vehicle can also be built in the cable 105.

[0035] The cooling pipe 101 and the conductor wire 102 are branched at the rear of the terminal 1 and are respectively connected to the terminal 1. The branched cooling pipe 101 is connected to the terminal expansion portion 40 described later of the terminal 1. In addition, the branched conductor wire 102 is inserted into the conductor wire connection portion 30 described later and is compressed and connected. In addition, although not shown in the figure, two terminals 1 for the + terminal and the - terminal and two cables 105 are provided on the housing 200.

[0036] Figure 1 The power supply connector 100 with a cable shown is used, for example, to charge a battery of an electric vehicle. The housing 200 of the power supply connector 100 with a cable includes: an insertion portion 201, in which a portion of the terminal 1 (the terminal contact portion 20) is configured to be exposed to the outside of the housing; a grip portion 202, which is configured behind the insertion portion 201; and a cable introduction portion 203, which is configured below the grip portion 202 (obliquely behind the insertion portion 201). The cable 105 is introduced from the outside of the housing 200 through the cable introduction portion 203 and into the housing 200 to be connected to the terminal 1.

[0037] The power supply connector with cable 100 according to the present embodiment includes a holder 60 .

[0038] For the power supply connector 100 with a cable having the above structure, the battery of the electric vehicle can be charged by inserting the insertion portion 201 into the charging port of the electric vehicle while holding the holding portion 202. When charging is completed, the insertion portion 201 of the housing 200 is pulled out from the charging port. At this time, since the power supply connector 100 with a cable has a retainer 60, the cooling pipe 101 inside the housing 200 will not vibrate, twist, or stretch due to the plugging and unplugging action of the power supply connector and the bending and stretching of the cable caused by the charging operation.

[0039] Next, the retainer 60 will be described in detail.

[0040] Figure 2 1 is a perspective view showing a terminal 1 assembled with a retainer 60 according to an embodiment. Figure 3 It is an exploded perspective view showing the retainer 60 according to one embodiment. Figure 4 It is a cross-sectional structural diagram of the retainer 60 according to one embodiment.

[0041] like Figure 2 and Figure 3 As shown, the holder 60 can be divided into divided pieces 60a, 60b (a first divided body 60a, a second divided body 60b).

[0042] The split piece 60a has a split surface 61. The split piece 60b is opposite to the split piece 60a via the split surface 61. The retainer 60 is formed by combining the split pieces 60a and 60b via the split piece 60a. In other words, the retainer 60 is an assembly obtained by combining the split pieces 60a and 60b. From the direction in which the terminal holding portion 62 and the tube holding portion 63 are arranged, the position of the split surface 61 overlaps with the terminal holding portion 62 and the tube holding portion 63.

[0043] The split pieces 60a and 60b are Figure 2 In the assembled state shown, the retainer 60 is fixed by being tied with a tie bar or a belt (not shown). In addition, the split pieces 60a and 60b may be provided with engaging claws such as fasteners to fix the split pieces 60a and 60b to each other. In the present embodiment, the retainer 60 can be divided into two split pieces 60a and 60b, but it can also be divided into more split pieces.

[0044] like Figure 3 As shown, the retainer 60 has: a terminal holding portion 62 and a tube holding portion 63. Specifically, the split piece 60a (first split body) has: a first terminal holding portion and a first tube holding portion. The split piece 60b (second split body) has: a second terminal holding portion and a second tube holding portion. That is, when the two split pieces 60a and 60b are combined, the terminal holding portion 62 is formed by the first terminal holding portion and the second terminal holding portion, and the tube holding portion 63 is formed by the first tube holding portion and the second tube holding portion.

[0045] like Figure 4 As shown in FIG. 1 , the terminal holding portion 62 holds the terminal 1. Figure 3 As shown, the tube holding part 63 holds the cooling tube 101. The tube holding part 63 sandwiches the terminal holding part 62 and is provided in a pair on both sides.

[0046] First, the structure of the terminal 1 and the cooling tube 101 held by the retainer 60 will be described. Figure 4 As shown, a refrigerant flow path 2 is formed in the terminal 1. The terminal 1 is suitable for rapid charging of a battery of an electric vehicle, and can cool Joule heat generated by a large current flowing through the refrigerant flow path 2.

[0047] The terminal 1 is a metal terminal, for example, formed of copper, copper alloy, etc. The surface of the terminal 1 is covered with a silver plating layer or the like to prevent corrosion. The terminal 1 includes: a terminal body 10, a terminal contact portion 20, and a conductor wire connection portion 30. The terminal body 10, the terminal contact portion 20, and the conductor wire connection portion 30 are integrally formed. Such a terminal 1 can be formed by casting or cutting an ingot (block).

[0048] The refrigerant flowing in the refrigerant flow path 2 is preferably an insulating refrigerant. By using an insulating refrigerant, it is possible to prevent leakage of electricity from the terminal 1 through the refrigerant flow path 2 to the cooler (not shown). Examples of insulating refrigerants include insulating oils such as silicone oil and mineral oil, fluorine-based refrigerants, and alcohol-based refrigerants. However, if an insulating layer, an insulating film, or the like is formed on the inner wall surface of the refrigerant flow path 2, a non-insulating refrigerant can also flow.

[0049] The terminal body 10, the terminal contact portion 20, and the conductor wire connection portion 30 are arranged on the same axis with the central axis O of the terminal 1 as a common axis. Hereinafter, the direction along the central axis O is referred to as the axial direction, the direction intersecting the central axis O from the axial direction is referred to as the radial direction, and the direction circumferentially around the central axis O is referred to as the circumferential direction. In addition, the position of the terminal contact portion 20 relative to the terminal body 10 in the axial direction, or the direction from the terminal body 10 toward the terminal contact portion 20 is referred to as the "front". On the other hand, the position of the conductor wire connection portion 3 relative to the terminal body 100, or the direction from the terminal body 10 toward the conductor wire connection portion 30 is referred to as the "rear".

[0050] A refrigerant flow path 2 is formed inside the terminal body 10. The refrigerant flow path 2 is formed by a hole portion 11 extending in the radial direction, a first inclined hole portion 41 connected to one end side (first end side) of the hole portion 11, and a second inclined hole portion 42 connected to the other end side (second end side) of the hole portion 11. One end of the hole portion 11 is opened through the terminal body 10, and the other end of the hole portion 11 is closed without penetrating the terminal body 10. In addition, the opening 11a at one end of the hole portion 11 is closed by the plug 50.

[0051] The first inclined hole portion 41 and the second inclined hole portion 42 penetrate and open through a pair of terminal expansion portions 40 protruding to the side of the terminal main body portion 10. The first inclined hole portion 41 is formed on one terminal expansion portion 40A (first terminal expansion portion) of the terminal expansion portion 40. The inlet 2a of the refrigerant flow path 2 is opened to the outside through the first inclined hole portion 41. In addition, the outlet 2b of the refrigerant flow path 2 is formed on the other terminal expansion portion 40B (second terminal expansion portion) of the terminal expansion portion 40.

[0052] The outer surface of the terminal expansion portion 40 is formed with: a first inclined portion 44, which is separated from the central axis O as it moves backward from the plane portion 43 parallel to the central axis O of the terminal 1; and a second inclined portion 45, which approaches the central axis O as it moves backward from the first inclined portion 44. The angle (elevation angle) of the first inclined portion 44 relative to the plane portion 43 is an acute angle of less than 45 degrees, for example, 30 degrees. In addition, the angle (relief angle) of the second inclined portion 45 relative to the first inclined portion 44 is a right angle of, for example, 90 degrees. That is, the terminal expansion portion 40 is roughly a right triangle shape in a side view.

[0053] The inlet 2a and the outlet 2b of the refrigerant flow path 2 are formed on the second inclined portion 45. That is, the inlet 2a and the outlet 2b of the refrigerant flow path 2 are opened obliquely to the rear. The cooling pipe 101 is connected to the inlet 2a and the outlet 2b via the pipe connector 101a. The cooling pipe 101 is formed of a resin pipe such as nylon, and has flexibility. In addition, the cooling pipe 101 has a certain degree of elasticity relative to bending, that is, the so-called rebound force and restoring force.

[0054] The terminal contact portion 20 protrudes forward of the terminal body 10. The terminal contact portion 20 of this embodiment is a solid pin-shaped (male terminal contact portion) extending in the axial direction. Since the refrigerant flow path 2 is not formed in the terminal contact portion 20, the cross-sectional area of ​​the conductor can be ensured to be large, which is suitable for the flow of large currents. A flange 21 is formed at the root of the terminal contact portion 20. The flange 21 is connected to the housing 200 (see Figure 1 ) engages, determining the limit of the terminal contact portion 20 protruding from the housing 200. In addition, the terminal contact portion 20 of the present embodiment is pin-shaped, and the component or device on the object side into which the terminal contact portion 20 is inserted can have a socket-shaped (female terminal contact portion) shape like the terminal contact portion 22.

[0055] The conductor wire connection portion 30 protrudes to the rear of the terminal body portion 10. The conductor wire connection portion 30 is a cylindrical portion extending in the axial direction. The conductor wire connection portion 30 includes: a first hole portion 31 extending in the axial direction and opening to the rear; and a second hole portion 32 extending from the inner wall surface of the first hole portion 31 to the radial outside and opening on the outer peripheral surface of the conductor wire connection portion 30. The first hole portion 31 is an insertion hole for the conductor wire 102. The second hole portion 32 is an exhaust hole for exhausting air when the plating liquid fills the first hole portion 31 when the terminal 1 is electroplated.

[0056] A taper 33 is formed in the conductor wire connection portion 30. The taper 33 is located in front of the terminal body 10, that is, closer to the terminal body 10 than the rear side of the conductor wire connection portion 30. The taper 33 is a conical portion whose radial dimension gradually increases from the terminal body 10 toward the rear. A cylindrical intermediate narrowing portion 12 is formed between the terminal body 10 and the taper 33. The radial dimension of the intermediate narrowing portion 12 is the same as the minimum diameter of the taper 33, and is smaller than the radial outer dimensions of the terminal body 10 and the conductor wire connection portion 30.

[0057] The terminal holding portion 62 of the holder 60 holds the conductor wire connection portion 30 and the intermediate narrowing portion 12. The terminal holding portion 62 includes a first receiving portion 62a that receives the conductor wire connection portion 30, a second receiving portion 62b that receives the tapered portion 33, and a third receiving portion 62c that receives the intermediate narrowing portion 12. The first receiving portion 62a, the second receiving portion 62b, and the third receiving portion 62c are connected in the axial direction with the central axis O as a common axis.

[0058] The first housing portion 62a is a cylindrical hole portion formed with a size equal to or slightly larger than the cylindrical portion of the conductor wire connecting portion 30. The second housing portion 62b is a conical hole portion arranged in front of the first housing portion 62a and formed with a size equal to or slightly larger than the tapered portion 33. The third housing portion 62c is a cylindrical hole portion arranged in front of the second housing portion 62b and formed with a size equal to or slightly larger than the intermediate narrowing portion 12.

[0059] The tube holding portion 63 of the retainer 60 holds the tube connector 101a and the cooling tube 101. The tube holding portion 63 includes a connector receiving portion 63a that receives the tube connector 101a and a tube receiving portion 63b that receives the cooling tube 101. The connector receiving portion 63a is a cylindrical hole portion formed with the same size as or slightly larger than the tube connector 101a. The connector receiving portion 63a extends obliquely rearward at the same angle as the inlet 2a and outlet 2b of the refrigerant flow path 2.

[0060] The tube receiving portion 63b is a hole portion formed with the same or slightly larger size as the cooling tube 101, with a smaller diameter than the connector receiving portion 63a and gently curved. Specifically, the tube receiving portion 63b has: a first straight portion 63b1, a curved portion 63b2, and a second straight portion 63b3. The first straight portion 63b1 is arranged on the same axis as the connector receiving portion 63a, and extends obliquely backward like the connector receiving portion 63a.

[0061] The first straight portion 63b1 extends in a direction intersecting the central axis O. In contrast, the second straight portion 63b3 extends parallel to the central axis O. The curved portion 63b2 is a portion that smoothly connects the first straight portion 63b1 and the second straight portion 63b3, and is curved along the cooling pipe 101. The curved portion 63b2 only needs to be curved at a curvature that does not buckle the cooling pipe 101.

[0062] The cooling pipe 101 is bent at a position rearward of the pipe gripping portion 63. The curvature of the curved portion 63b2 is smaller than the curvature of the cooling pipe 101 at a position rearward of the pipe gripping portion 63.

[0063] Specifically, if Figure 1As shown, the cooling pipe 101 protrudes from the holder 60 at a position behind the holder 60 and extends toward the inside of the power line 103 in a manner of being greatly bent.

[0064] In other words, at the rear of the retainer 60, the cooling pipe 101 is Figure 4 The central axis O shown extends in an inclined direction. In addition, the cooling pipe 101 built in the power line 103 extends in a direction parallel to the gripping portion 202 .

[0065] In the power supply connector 100 with a cable having such a structure, in order to insert the cooling pipe 101 exposed from the power line 103 into the holder 60 , the cooling pipe 101 is bent at a position behind the holder 60 .

[0066] On the other hand, since the curvature of the curved portion 63b2 is set smaller than the curvature of the cooling pipe 101 at the rear position of the holder 60, the curvature amount (degree of curvature) of the cooling pipe 101 arranged at the curved portion 63b2 becomes smaller.

[0067] Therefore, the load on the cooling pipe 101 due to bending is unlikely to occur at the connection portion between the terminal 1 and the cooling pipe 101, and the refrigerant leakage can be prevented.

[0068] An anti-slip member 70 is disposed near the exit of the second straight portion 63b3. The anti-slip member 70 is formed of rubber, sponge, etc., and is interposed between the tube gripping portion 63 and the cooling tube 101 to suppress the sliding of the cooling tube 101. The anti-slip member 70 may be disposed on the inner wall surface of the tube gripping portion 63, or may be wound around the outer circumference of the cooling tube 101.

[0069] The retainer 60 has a fitting portion 64 fitted into the intermediate narrowed portion 12 of the terminal 1. The fitting portion 64 is formed by a partition wall portion separating the terminal holding portion 62 and the tube holding portion 63. In the present embodiment, the partition wall portion between the tube receiving portion 63b and the second receiving portion 62b, and the partition wall portion between the second receiving portion 62b and the third receiving portion 62c serve as the fitting portion 64.

[0070] The power supply connector 100 with a cable having the above structure includes: a terminal 1; a cooling tube 101 that supplies a refrigerant to the terminal 1; and a retainer 60 that includes a terminal holding portion 62 that holds the terminal 1, and a tube holding portion 63 that holds the cooling tube 101. Therefore, the retainer 60 holds both the terminal 1 and the cooling tube 101, so that the cooling tube 101 follows the plugging and unplugging action of the terminal 1, and the positional relationship between the terminal 1 and the cooling tube 101 is kept constant. Therefore, the load acting on the connection portion between the terminal 1 and the cooling tube 101 can be reduced.

[0071] This prevents leakage of refrigerant from the connection portion between the terminal 1 and the cooling pipe 101 (for example, the connection portion between the terminal 1 and the pipe connector 101a or the connection (joint) portion between the pipe connector 101a and the cooling pipe 101).

[0072] In addition, the cooling pipe 101 has a certain degree of elasticity with respect to bending, that is, the so-called rebound force and restoring force, as described above, and Figure 1 Therefore, although a load (bending reaction force of the cooling tube 101) is always applied to the connection portion between the terminal 1 and the cooling tube 101, the cooling tube 101 is held by the retainer 60, so that the bending degree of the cooling tube 101 will not be greater (serious bending). Therefore, it is possible to prevent the load acting on the connection portion from increasing. In addition, it is possible to prevent the cooling tube 101 from being buckled.

[0073] In addition, in this embodiment, if Figure 2 and Figure 3 As shown, the retainer 60 is an assembly obtained by combining the divided pieces 60 a and 60 b , and therefore the retainer 60 can be easily assembled to the terminal 1 and the cooling tube 101 .

[0074] In addition, in this embodiment, if Figure 4 As shown, the tube holding portion 63 has a second straight portion 63b3 extending parallel to the central axis O of the terminal 1. Therefore, the cooling tube 101 can be arranged in a manner that the track of the cooling tube 101 does not expand relative to the terminal 1, and it is also easy to insert. Figure 1 The narrow space inside the housing 200 is shown.

[0075] In addition, in this embodiment, if Figure 4 As shown, the tube gripping portion 63 has a bent portion 63b2 that is bent along the cooling tube 101, so that the cooling tube 101 can be gripped without strongly bending the cooling tube 101. That is, the load acting on the cooling tube 101 can be reduced.

[0076] In addition, in this embodiment, since the anti-slip member 70 is provided between the tube gripping portion 63 and the cooling tube 101, the cooling tube 101 can be firmly gripped by the tube gripping portion 63 via the anti-slip member 70. In addition, the cooling tube 101 is less likely to be twisted.

[0077] In this embodiment, the terminal 1 has the narrowed portion 12 and the retainer 60 has the fitting portion 64 fitted in the narrowed portion. Therefore, the retainer 60 cannot be pulled out relative to the terminal 1 in the axial direction, and the fitting between the terminal 1 and the retainer 60 is strengthened.

[0078] The preferred embodiments of the present invention are described above, but are only illustrative and non-limiting. Additions, omissions, substitutions, and other changes can be made without departing from the scope of the present invention. Therefore, the present invention is not limited by the above content, but by the claims.

[0079] For example, in the above embodiment, a method of connecting the cooling pipe 101 to the terminal 1 having the refrigerant flow path 2 inside is illustrated, and for example, a method of providing a groove or a hole in the terminal 1 and inserting a metal pipe, and connecting the cooling pipe 101 to the metal pipe may also be used. According to this structure, the refrigerant can be supplied to the terminal 1 via the cooling pipe 101, and the terminal 1 can be cooled.

[0080] In addition, in the above embodiment, the cooling pipe 101 connected to the terminal 1 is described, but the present invention is not limited to this structure. A structure in which a connecting component is arranged between the terminal 1 and the cooling pipe 101, and the terminal 1 and the cooling pipe 101 are connected via the connecting component may also be adopted. In this case, the connecting component may be flexible or not. If the cooling pipe 101 is flexible, the above-mentioned effect can be obtained.
