a power mating portion disposed on the second surface, wherein the power mating portion includes a plurality of column bodies, each of the plurality of column bodies has a first end and a second end, and the first end is connected to the second surface, wherein the plurality of first channels respectively penetrate the plurality of column bodies, and wherein in each of the first channels, two first openings are formed on the first surface and the second end of a corresponding one of the column bodies, respectively;
a signal mating portion disposed on the third surface, wherein the signal mating portion has a fifth surface and a sixth surface disposed opposite to each other, wherein a plurality of second channels are formed inside the signal mating portion in the first direction, and in each of the second channels, two second openings are formed on the fifth surface and the sixth surface, respectively; and
a snap-fit member disposed on the fourth surface, wherein the snap-fit member includes a press portion and a snap-fit portion, wherein a projection area of the press portion projected onto the fourth surface at least partially overlaps with a projection area of the signal mating portion projected onto the fourth surface.

2. The insulating housing according to claim 1 , wherein the fifth surface is flush with the first surface.

3. The insulating housing according to claim 1 , wherein a fillet is formed at a junction between the first surface and the third surface, and the fillet has a radius of curvature between 0.5 mm and 0.8 mm.

4. The insulating housing according to claim 1 , wherein a plurality of recesses are formed at positions on the third surface corresponding to positions of the plurality of second openings on the fifth surface.

5. The insulating housing according to claim 1 , wherein the press portion includes a convex portion, the convex portion is a protruding portion formed on one side of the snap-fit member near one side of the first surface, and a projection area of the convex portion projected onto the fourth surface overlaps with the projection area of the signal mating portion projected onto the fourth surface.

6. The insulating housing according to claim 5 , wherein the first surface and the fifth surface are spaced apart by a first horizontal distance in the first direction, the convex portion has an inclined surface and a horizontal surface, a junction between the horizontal surface and the inclined surface is spaced apart from the first surface by a second horizontal distance, and the first horizontal distance is less than the second horizontal distance.

7. The insulating housing according to claim 1 , wherein the snap-fit member includes a fan-shaped portion, and the fan-shaped portion is connected between the snap-fit portion and the press portion.

8. The insulating housing according to claim 7 , wherein the press portion has a first width and the snap-fit portion has a second width, and the first width is at least 1.5 times the second width.

9. A wire-end connector, comprising:
a body portion having a plurality of first channels formed therein;
a power mating portion disposed on one side of the body portion, wherein the power mating portion includes a plurality of column bodies, wherein the plurality of first channels respectively penetrate the plurality of column bodies in a first direction;
a signal mating portion disposed on one surface of the body portion, wherein a plurality of second channels are formed inside the signal mating portion in the first direction;
a plurality of power wire-end terminals disposed in the plurality of first channels, respectively;
a plurality of signal wire-end terminals disposed in the plurality of second channels, respectively; and
a snap-fit member disposed on another surface of the body portion opposite to the one surface of the body portion, wherein the snap-fit member includes a press portion and a snap-fit portion, and a projection area of the press portion projected onto the another surface at least partially overlaps with a projection area of the signal mating portion projected onto the another surface.

10. The wire-end connector according to claim 9 , wherein a length of an overlapping projection area in the first direction of the press portion and the signal mating portion projected onto the surface is greater than or equal to half of a length of the projection area in the first direction of the press portion projected onto the surface.

11. The wire-end connector according to claim 9 , wherein the press portion further includes a convex portion, and a projection area of the convex portion projected onto the surface at least partially overlaps with a projection area of the signal mating portion projected onto the surface.

12. The wire-end connector according to claim 9 , wherein the press portion has a first width and the snap-fit portion has a second width, and the first width is at least 1.5 times the second width.

13. The wire-end connector according to claim 9 , wherein the first width is greater than or equal to 6 mm.

14. The wire-end connector according to claim 9 , wherein one side of the body portion is flush with one side of the signal mating portion.

15. The wire-end connector according to claim 9 , wherein a fillet is formed at an edge corner of the body portion near the signal mating portion, and the fillet has a radius of curvature between 0.5 mm and 0.8 mm.

16. The wire-end connector according to claim 9 , wherein a plurality of recesses are formed at the edge corner of the body portion near the signal mating portion and at positions corresponding to positions of the plurality of second channels.

17. A wire-end connector, comprising:
