In the direction from bottom to top, the cross-sectional diameter of the wire management islands 111 can be gradually reduced, so that the distance between the top ends of two adjacent wire management islands 111 is larger, and the lead can be conveniently placed. In addition, the top end of the wire arranging island 111 and the edge of one side close to the accommodating cavity can be in smooth transition, and damage to the lead can be reduced.

The bottom surface of the casing 110 is provided with a plurality of supporting protrusions 112, the supporting protrusions 112 can be abutted against the circuit board, so that a certain gap exists between the bottom surface of the casing 110 and the circuit board, and the following advantages are mainly achieved: 1. the heat dissipation of the circuit board is facilitated, air cooling is needed during welding, and ventilation can be facilitated through gaps; in addition, as the circuit board is provided with a plurality of circuits, the circuits can generate heat in the working process and discharge the heat in time, thereby being beneficial to the normal work of the circuits and prolonging the service life of the circuit board; 2. when the network transformer 10 is removed, tweezers and the like can be inserted into the gap between the bottom surface of the shell 110 and the circuit board, so that the network transformer 10 can be tilted conveniently; 3. the network transformer 10 can still be accurately mounted when there is a slight deformation of the circuit board.

For example, in the embodiment, the supporting protrusions 112 are hemispherical, that is, the outer surface of the supporting protrusions 112 is spherical, so that the contact area between the supporting protrusions 112 and the circuit board can be further reduced, which is beneficial to heat dissipation of the circuit board; the number of the supporting protrusions 112 is four, and the four supporting protrusions 112 are distributed in a rectangular shape and close to two ends of the housing 110, so that the network transformer 10 can be more stable after being installed and is not easy to shake.

In other embodiments, the supporting protrusions 112 may also be cylindrical, rectangular parallelepiped, irregular, etc., and the number of the supporting protrusions 112 may also be three, five, etc., and generally, all the supporting protrusions 112 may not be located on the same straight line.
