The following describes the implementation of the present invention in detail with reference to specific embodiments.

Referring to fig. 1, 2 and 3, a preferred embodiment of the present invention is provided.

The utility model provides a liquid cooling terminal fixes on the direct current rifle that charges for the conductor cable of fixed direct current rifle that charges cools off the conductor cable, include:

the terminal comprises a terminal body 1, an adapter 2, a crimping pipe 3, a liquid cooling pipe 4 and a fixing structure 5.

Specifically, the fixing structure 5 includes a first nut 51 and a second nut 52.

More specifically, the terminal body 1 has a first threaded pipe 11 and a second threaded pipe 12.

More specifically, one end of the adapter 2 is fixedly connected to the liquid cooling pipe 4, the other end of the adapter 2 is embedded into the first threaded pipe 11, and the first nut 51 is embedded into the outer side of the first threaded pipe 11, so that the adapter 2 and the first threaded pipe 11 are fixed.

More specifically, the crimp tube 3 is disposed inside the second threaded tube 12, and the second nut 52 is fitted to the outside of the second threaded tube 12.

It should be noted that the crimping tube 3 is used to fix the conductor cable by a crimping process.

More specifically, the crimp tube 3 has a through hole 31 formed therein.

The through hole 31 communicates the inside of the crimp tube 3 with the inside of the second threaded tube 12, and the conductor cable in the crimp tube 3 is cooled by feeding a cooling liquid into the crimp tube 3.

It is understood that the coolant inside the crimp tube 3 will overflow the crimp tube 3 through the through hole 31 and enter the inside of the second threaded tube 12, and the second nut 52 closes the second threaded tube 12 due to the second nut 52 being fitted to the outside of the second threaded tube 12, so that the coolant overflowing from the through hole 31 will not overflow the second threaded tube 12 but enter the inside of the terminal body 1.

More specifically, the second threaded pipe 12 has the tooling holes 121 formed therein, and the tooling holes 121 and the via holes 31 are at the same level.

It should be noted that, the height of via hole 31 in the conventional design is higher than that of second threaded pipe 12, so can directly process crimping pipe 3 to generate via hole 31, and in the design provided by the utility model, the height of via hole 31 moves down to the height that can be sheltered from by second threaded pipe 12, at this moment because sheltering from of second threaded pipe 12, can't directly process via hole 31 on crimping pipe 3, therefore need process hole 121 that the level of via hole 31 unanimous on second threaded pipe 12 earlier, so as to conveniently process via hole 31 on crimping pipe 3.

Note that the via hole 31 functions to overflow the coolant, and the second nut 52 functions to prevent the coolant overflowing from the via hole 31 from overflowing the second threaded pipe 12, so the height of the second nut 52 needs to cover the via hole 31.

It can be understood that the lower the level of the via hole 31, the lower the height required for the second nut 52, and the smaller the space occupied by the terminal body 1.

1. the utility model provides a be provided with conducting hole 31 on the crimping pipe 3 of liquid cooling terminal, and the highly downwardly moving of conducting hole 31 to the height that can be sheltered from by second screwed pipe 12, because the highly lapse of conducting hole 31, the required height of second nut 52 also moves down, and the space that the terminal protection body occupied just also is littleer, has solved the more problem in liquid cooling terminal occupation space among the prior art.

2. When the via hole 31 is blocked by the second threaded pipe 12, the via hole 31 cannot be directly formed in the crimp pipe 3, and therefore, the via hole 31 is formed by forming the pilot hole 121 having the same level as the via hole 31 in the second threaded pipe 12.

In some embodiments, the terminal body 1 has a first fluid channel 13 therein, and the adapter 2 has a second fluid channel 14 therein.

Specifically, when the terminal body 1 and the adapter 2 are fixedly connected, the first liquid guide groove 13 and the second liquid guide groove 14 communicate with each other, and a cooling liquid flows through the inside.

In some embodiments, a fixation portion 6 is also included.

Specifically, the fixing portion 6 is connected to the terminal body 1 and is configured to be fixedly mounted in the dc charging gun, so that the liquid cooling terminal is fixed to the dc charging gun.

In some embodiments, the adapter 2 includes a first straight tube 21, an arc tube 22 and a second straight tube 23 connected in sequence.

Specifically, first straight tube 21 and terminal body 1 fixed connection, second straight tube 23 and liquid cooling pipe 4 fixed connection, the inside intercommunication of first straight tube 21, curved tube 22 and second straight tube 23 for supply the coolant liquid inside circulation.

More specifically, the outer side of the second straight pipe 23 and the inner side of the liquid cooling pipe 4 are respectively provided with a protruding structure and a recessed structure which can be mutually embedded, and the protruding structure and the recessed structure can be mutually embedded through rotation, so that the second straight pipe 23 and the liquid cooling pipe 4 can be fixedly connected.

In some embodiments, the first straight tube 21 has a flange 211 thereon.

Specifically, the flange 211 has a convex disk shape, so that the flange 211 can abut against the first nut 51 and be fixed in the first threaded pipe 11 by the first nut 51, thereby fixing the adapter 2.

In some embodiments, a seal 7 is also included.

In particular, the seal 7 comprises a seal ring arranged between the first threaded pipe 11 and the first nut 51, more particularly, the seal 7 comprises several seal rings.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
