Thus, the elasticity and the sealing performance of the silica gel are good.
Further, referring to fig. 1 to 10, as a specific embodiment of the charging device provided by the present invention, the insulating and heat conducting sleeve 3 is a ceramic integral piece. Thus, the ceramic has good heat conduction and good ceramic insulation.
Further, referring to fig. 1 to 10, as a specific embodiment of the charging device provided by the present invention, the heat conducting and dissipating member 4 is fixed to the first base 61 and the second base 62 by screws. Thus, the fixing is convenient.
Further, referring to fig. 1 to 10, as a specific embodiment of the charging device provided by the present invention, the elastic deformation distance of the first elastic ring 511 and the second elastic ring 521 in the extending direction of the power supply terminal 2 is greater than the clearance distance of the power supply terminal 2 swinging relative to the first base 61/the second base 62. In this way, the power supply terminal 2 drives the heat conducting insulating sleeve to shake, and the heat conducting insulating sleeve can be released by the elastic deformation of the first elastic ring 511 and the second elastic ring 521.
Specifically, in one embodiment, the heat dissipation device further includes a gun head 11, and the gun head 11 and the first base 61 are sequentially fixed on the heat conduction heat dissipation element 4 by screws.
Specifically, in one embodiment, the edges of the cross section of the first annular rib 513 are arcuate; the edge of the cross section of the second annular rib 523 is circular arc-shaped. As such, when the first annular rib 513 contacts the first seat 61/external structure, the first annular rib 513 is more easily deformed by being pressed to obtain a reverse elastic force, further increasing the elastic force of the first annular flange 512; the surface of the circular arc-shaped first annular rib 513 can facilitate sliding of the first annular rib 513 along the first seat 61/outer structural surface; when the second annular rib 523 contacts the second seat 62/external structure, the second annular rib 523 is more easily deformed by being pressed to obtain a reverse elastic force, further increasing the elastic force of the second annular flange 522; the surface of the circular-arc-shaped second annular rib 523 can facilitate sliding of the second annular rib 523 along the second seat 62/external structural surface.
Specifically, in one embodiment, the first elastic ring 511, the first annular flange 512, and the first annular rib 513 are integral pieces of silicone, and the second elastic ring 521, the second annular flange 522, and the second annular rib 523 are integral pieces of silicone. Thus, the first elastic ring 511 has good elasticity and sealing property; the second elastic ring 521 has good elasticity and sealing property.
In particular, in one embodiment, the insulating and thermally conductive sleeve 3 is a ceramic-made integral piece. Thus, the ceramic has good heat conduction and good ceramic insulation.
Specifically, in one embodiment, the elastic deformation distance of the first elastic ring 511 and the second elastic ring 521 in the extending direction of the power supply terminal 2 is greater than the distance that the power supply terminal 2 moves relative to the first housing 61/the second housing 62. In this way, the power supply terminal 2 can be released by the elastic deformation of the first elastic ring 511 and the second elastic ring 521 in the shaking process of the insulating heat conducting sleeve 3.
Specifically, in one embodiment, the gun head 11 is further included, and the gun head 11 and the first base 61 are fixed on the heat conducting and dissipating member 4 in sequence by using screws, so as to avoid the power supply terminal 2 from being deviated due to the change of the relative positions of the gun head 11, the first base 61 and the heat conducting and dissipating member 4. Since the falling manner of the charging device is uncertain, the insulating and heat conducting sleeve 3 may be subjected to only axial or only radial impact force, and then the charging device may be buffered by the first elastic ring 511 and the second elastic ring 521, or the first annular flange 512 and the second annular flange 522, and the buffering effect is enhanced by setting the first circular arc-shaped annular rib 513 and the second circular rib 523.
More likely, the charging device is subjected to a huge bending force, and the insulating heat conducting sleeve 3 is subjected to axial and radial impact forces at the same time, so that the first elastic ring 511, the first annular flange 512, the second elastic ring 521 and the second annular flange 522 are required to jointly generate reverse elastic force, and breakage caused by deflection of the insulating heat conducting sleeve 3 is avoided.
The charging equipment receives the exogenic action, leads to power supply terminal 2 in the clearance internal activity of the through-hole of first cavity, has taken place the skew to driven insulating heat conduction sleeve 3 and taken place the skew, through setting up insulating heat conduction sleeve 3 and being greater than the movable clearance of power supply terminal 2 in the through-hole of first cavity between power supply terminal 2 and heat conduction radiating member 4, how power supply terminal 2 drives insulating heat conduction sleeve 3 promptly and takes place the skew, insulating heat conduction sleeve 3 can not take place hard collision with heat conduction radiating member 4 and break. Since the insulating heat conducting sleeve 3 and the power supply terminal 2 are in clearance fit, the clearance is as small as possible, but the clearance cannot be avoided, in order to avoid cracking caused by mutual shaking between the power supply terminal 2 and the insulating heat conducting sleeve 3, the insulating heat conducting sleeve 3 is clamped and fixed by arranging the first elastic ring 511 and the second elastic ring 521, when the insulating heat conducting sleeve 3 deflects, the vertical horse is buffered by reverse elastic force to avoid cracking, and the clearance is smaller than the clearance between the insulating heat conducting sleeve 3 and the heat conducting and radiating member 4 after the first elastic ring 511 and the second elastic ring 521 are assembled with the insulating heat conducting sleeve 3, namely, when the insulating heat conducting sleeve 3 deflects towards the direction of the heat radiating member, the first elastic ring 511 or the second elastic ring 521 firstly contacts, and the first elastic ring 511 or the second elastic ring 521 still can elastically deform when the insulating heat conducting sleeve 3 deflects to the maximum, so that the insulating heat conducting sleeve 3 is prevented from being in hard contact with the first elastic ring 511 or the second elastic ring 521 and always kept in an elastic range.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
