Embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer, the utility model is described in detail below in conjunction with accompanying drawing and specific embodiment.

See also Fig. 1 to shown in Figure 3, the electric connector 100 of the utility model comprises insulating body 10 and is contained in the some power supply terminals in the said insulating body 10, and said some power supply terminals are provided with in pairs, and said electric connector 100 also comprises some signal terminals 30.

See also Fig. 4 to shown in Figure 6, said insulating body 10 comprises the docking section 12 that main part 11 and autonomous body 11 extend forward, and said docking section 12 is provided with interface 121 in order to cooperate with butt connector (not shown).Said insulating body 10 is provided with some spaced walls 13; Be formed with between said some spaced walls 13 the plurality of terminals host cavity in order to accommodate respectively said some power supply terminals to 20 with some signal terminals 30; In this execution mode; Because said some power supply terminals are not quite similar with the shape of said some signal terminals 30 to 20, thereby 20 the first terminal host cavity 141 and shape in order to the second terminal accommodating chamber 142 of accommodating said some signal terminals 30 also are not quite similar in order to accommodate said some power supply terminals.

Said the first terminal host cavity 141 comprises along what electric connector 100 short transverses were extended and supports wall 143; The said wall 143 that supports is provided with arrival slot 1431; Said supporting between wall 143 and the said spaced walls 13 left gap 144; Said gap 144 is connected with said the first terminal host cavity 141, thus can be used to accommodate and fixing said power supply terminal to 20, limited said power supply terminal to 20 displacements along electric connector 100 length, width and short transverse.Also be provided with some accepting grooves 145 on the madial wall of said the first terminal host cavity 141.

The dual-side of said some spaced walls 13 all offers thermovent 131, and in this execution mode, said thermovent 131 is a U type recess, and said thermovent 131 is opened on said interface 121.Also be provided with some slug holes 15 on the said insulating body 10; Said some slug holes 15 are between two adjacent the first terminal host cavities 141; And be connected with said thermovent 131; By cooperating of said thermovent 131 and said slug hole 15, can make said power supply terminal that 20 heats that in said the first terminal host cavity 141, produce are distributed.
