While characterized as some particular aspects, but a variety of variants in terms of these and displacement each fall within the disclosure
In range.Although referring to some benefits and advantage of preferred aspect, the scope of the present disclosure has no intention specific by these
Benefit, purposes or purpose are limited.On the contrary, all aspects of this disclosure are intended to be widely used in automotive system and/or different
Wired and wireless technology, system configuration, network (including optical-fiber network), hard disk and transport protocol, it is some of in the accompanying drawings and
It is shown by way of illustration in being described below of preferred aspect.Specific description and attached drawing are only saying to the disclosure
Bright rather than limitation, the scope of the present disclosure are defined by the appended claims and the equivalents thereof.
Fig. 1 shows the charging station for rechargeable battery.For example, battery can be in electric vehicle.Charging station
Including power supply 12, power supply 12 is usually coupled to the utility network locating for house or business field.One or more output cables 14
From power supply 12s and connector 16 is terminated at, connector 16 is connected to for example that electric vehicle is not (during the charging process
Show) on charging input end mouth (not shown).
The a large amount of electricity of conductor carrying in order to be that large-sized battery charges within the relatively short time, in cable 14 and connector 16
Stream, which is usually hundreds of amperes.This will lead on conductor, and conductor and electric vehicle in connector 16
On charging input end mouth in conductor between link node on generate a large amount of resistance heat.As connector itself is manufactured
The smaller and smaller problem is increasingly prominent, this is because the material volume and surface area of the heat for region generation of dissipating compared with
It is small.It is therefore desirable for the amount by reducing charging current can not needed while reducing the size of connector 16 to limit heat.
Fig. 2 illustrates a solution of the problem.In the embodiment of fig. 2, charging station includes liquid coolant storage
Storage 18 is in fluid communication with the coolant channel 24 in connector.Pump 22 can make coolant fluid body circulation during the charging process
By channel 24, thus cooling connector 16.Coolant liquid may be, but not limited to, water, ethylene glycol or various oil-based fluids.
Fig. 3 A and 3B are shown with various sizes of EXEMPLARY CONNECTOR 16.Connector has main body 30, the main body 30
With joint face 28, which limits the plane of the longitudinal axis 26 perpendicular to main body.Longitudinal axis 26 exists along main body
The connecting pin of connector or the side of socket upwardly extend, and the charging port of the vehicles is inserted into generally along connector 16
Direction.Advantageously, joint face 28 has low clearance profile (low profile).Rectangle or ellipse be it is suitable,
In, perpendicularly to the longitudinal axis 26 size is longer than the other sizes at joint face 28.If having been found that joint face 28
Height be less than 20mm, or even less than 15mm, it is advantageous.Width is then smaller than 100mm or is less than 50mm.Therefore,
The surface area of joint face can be advantageously below 2000 square millimeters.Using these designs, connect along the width distribution of connector
Outbound is advantageous, because this allows for low-down profile elevations h.If round, then it is actually connected
The diameter of pin/socket 34 can be such as 12mm or 10mm, wherein biggish size is related to higher current-carrying capability.
Fig. 4 is shown can be positioned at a kind of embodiment of the component inside the connector 16 of Fig. 1-3.Output cable 40 couples
(such as welding) arrives busbar 42, which is coupled to the rear portion of pin/socket 34 again, which extends to or prolong
Stretch out the joint face 28 of connector 16.Can the heat pipe 44 made of the metal of such as copper be thermally coupled to busbar 42.Heat pipe 44
Also it is thermally coupled to cooling duct 48.Because cable 40 can be at high voltage relative to ground connection, advantageously by cable 40 with
Fluid in cooling duct 48 is electrically isolated.This can by include silicone mat between busbar 42 and heat pipe 44 or other
Relatively thermally conductive but electrical isolation material is completed.Cooling duct can also with or optionally formed by polymer film, the polymer film
Fluid in channel is electrically isolated with heat pipe 44.Cooling fluid can pass through the entrance and exit connector with connector sheet
(such as female Luer or the like) enters and leaves cooling duct or channel can up and down reciprocatingly roll over all along cable 14
It returns the reservoir 18 for reaching charging station and is returned from the reservoir 18 of charging station, wherein for example, reservoir is desirably integrated into figure
In 1 power supply 12.Thermocouple 46 or other temperature sensors can be attached to the busbar or other positions of connector 16, with
The temperature of connector during monitoring charging cycle.This can be electrically charged station for controlling pump 22, so that only when temperature height is to enough
When being approved using liquid coolant, coolant liquid just cycles through cooling duct.
Fig. 5 shows the exemplary configuration of cooling duct 50.Surface area can be increased by anterior-posterior approach, the front and back road
Diameter can be engaged with the mating structure on heat pipe 44, such as maximize the contact surface between cooling duct 50 and heat pipe 44
