Used as further improvement of the utility model, the upper fin includes a horizontal plate, and the shell fragment is from level Piece is protruded out and formed.

Used as further improvement of the utility model, the horizontal plate has because forming some through holes that shell fragment leaves.

Used as further improvement of the utility model, the roof has a upper recess, the level towards spliced eye indent Piece is fixed in upper recess.

Used as further improvement of the utility model, the upper fin laser welding is on roof.

Used as further improvement of the utility model, the shell fragment lines up some rows along the longitudinal direction.

Used as further improvement of the utility model, the electric connector is additionally provided with the radiating once being fixed on bottom wall Piece, the lower fin is also to be made up of metal material, and the lower fin has downwardly projecting some shell fragments in bottom wall.

Used as further improvement of the utility model, the bottom wall has a lower concave part towards spliced eye indent, described lower scattered Backing has the horizontal plate being fixed in lower concave part, and the shell fragment of the lower fin is protruded out from horizontal plate and formed.

As further improvement of the utility model, the lower fin also laser welding on bottom wall.

The upper fin of the utility model electric connector is fixed on the roof of metal shell, the upper fin have to Convex some shell fragments for metal shell, shell fragment can form reliable contact with rack or radiator Elastic Contact, eliminate The air gap between them, improves heat conduction efficiency, improves radiating effect, in addition, upper fin has easily production, Yi Yun With the characteristics of, compact conformation itself has space to ventilate, it may have good radiating effect.

Specific embodiment

Refer to shown in Fig. 1 to Fig. 4, the utility model electric connector 100, be used to be installed on circuit board 200, inserted for one Head connector（It is not shown）Plug, electric connector 100 include a metal shell 10, metal material be made one on fin 21, Fin once 22 and the pedestal in metal shell 10 that metal material is made（It is not shown）, conducting end is provided with pedestal Son, for being docked with plug connector.Upper fin 21 is fixed on metal shell 10, and lower fin 22 is fixed on metal shell Under 10.

Metal shell 10 includes the two side of the bottom wall 12 relative with roof 11 of roof 11 and connection roof 11 and bottom wall 12 13, roof 11, bottom wall 12 surround a spliced eye 14 with two side 13, are plugged with for plug connector.Roof 11 is towards grafting The indent of hole 14 has a upper recess 111, and bottom wall 12 has a lower concave part 121 towards the indent of spliced eye 14.

Upper fin 21 and lower fin 22 each include being contained in correspondence upper recess 111, a horizontal plate of lower concave part 121 211st, 221 and some shell fragments 212,222 of metal shell 10 are protruded out from horizontal plate 211,221, horizontal plate 211,221 has shape Into some through holes 213,223 that shell fragment 212,222 leaves, horizontal plate 211,221 is also fixed on roof 11, bottom by laser welding On wall 12, some shell fragments 212,222 line up some rows along the longitudinal direction, wherein, some shell fragments 212 of upper fin 21 are certainly Horizontal plate 211 upwards, tilt backwards extension and form, to outside cabinet or radiator Elastic Contact, realize heat transfer, it is lower to dissipate Some shell fragments 222 of backing 22 be from horizontal plate 221 downwards, the extension that turns forward form, to the elastic connecting of circuit board 200 Touch, realize heat transfer.

When electric connector 100 is arranged on circuit board 200, the shell fragment 222 of lower fin 22 presses on the upper table of circuit board 200 Face.When plug connector inserts 10 spliced eye 14 of metal shell, the upper recess of plug connector and roof 11 and bottom wall 12 111st, contacted at the position of lower concave part 121, by conducting heat to upper fin 21, lower fin 22, upper fin 21 leads to again Cross shell fragment 212 and conduct heat to outside cabinet or radiator well, lower fin 22 is again by shell fragment 222 well by warm Amount is transmitted to circuit board 200, and good thermolysis is played inside electric connector 100.

The upper fin 21 of the utility model electric connector 100 and lower fin 22 are by shell fragment 212,222 elastic connectings Outside cabinet or radiator and circuit board 200 are touched, contact is reliable, eliminates the air gap between them, improve heat transfer effect Rate, improves radiating effect.Upper fin 21 and lower fin 22 have easily production, easily with the characteristics of, compact conformation, itself has Space can ventilate, it may have good radiating effect.

Although being example purpose, preferred embodiment of the present utility model, the common skill of this area are had been disclosed for Art personnel by, it is realized that disclosed in not departing from by appending claims scope and spirit of the present utility model situation Under, various improvement, increase and substitution are possible.
