[0037] The connection part 22 can be arranged in a generally straight line shape, and the connection part 22 is recessed inwards at both sides near the other end thereof, so that the width of the connection part 22 at this location is smaller than the width at both ends of the location, that is, the width of the connection part 22 at this location is partially reduced, thereby forming a narrowing portion 221. It can be understood that the wire of the core unit can be wound around the narrowing portion 221, so that the wire is fixed and is not easy to slide on the connection part 22.

[0038] The positioning portion 23 includes a positioning section 231, and the extension direction of the positioning section 231 is opposite to the extension direction of the pin portion 21. It can be understood that when the pin structure 2 is installed in the housing 1, the positioning section 231 can cooperate with the housing 1 to achieve the positioning installation of the pin structure 2, and the pin portion 21 extends toward the side facing away from the housing 1 to facilitate connection with the RJ45 connector. Among them, the wiring portion 22 and the plane where the positioning portion 23 are located are set at an angle, including the wiring portion 22 and the plane where the positioning section 231 is located are set at an angle.

[0039] The positioning section 231 may be parallel to the pin portion 21, that is, the positioning section 231 and the pin portion 21 extend in opposite and parallel directions. Of course, in other embodiments, the positioning section 231 may not be parallel to the pin portion 21, for example, the angle between the two is close to 0° or 180°.

The second convex portion 222 may include at least one protrusion, and the at least one protrusion may be arranged at intervals along the extension direction of the wiring portion 22.

[0048] Of course, in other embodiments, the second protrusion 222 may be disposed only on the outer surface of the wiring portion 22 close to the positioning section 231 , or only on the outer surface of the wiring portion 22 away from the positioning section 231 .

[0049] The second protrusion 222 may be disposed between one end of the wiring portion 22 connected to the pin portion 21 and the narrowing portion 221 , thereby achieving the matching of the wiring portion 22 with the housing 1 without affecting the winding of the wire.

[0050] The pin structure 2 is an integrally formed structure. Optionally, the pin structure 2 can be formed by a copper sheet through a stamping process. The stamping die 20 can be formed by a stamping die 20 such as Figure 6 The stamping die 20 shown is used to realize the above. Of course, the pin structure 2 can also be made of other materials with good electrical conductivity.

[0051] Combination Figure 2 and Figure 5 As shown, the housing 1 of the network transformer 10 is provided with a receiving groove 11 for receiving the core unit on the inner side, and a plurality of mounting grooves 13 are provided on the side 12 of the housing 1. It can be understood that the housing 1 includes at least two side portions 12 arranged along the circumference, and the at least two side portions 12 jointly define and enclose the receiving groove 11.

The pin portion 21 extends toward the side away from the receiving groove 11, and the other end of the wiring portion 22 extends out of the housing 1 from the top of the mounting groove 13 and communicates with the receiving groove 11.

[0053] Specifically, combined Figure 2 and Figure 4 As shown, the mounting groove 13 has a first opening 131 on a side away from the accommodating groove 11, and the shape of the mounting groove 13 is adapted to the shape of the pin structure 2, so that the pin structure 2 can be moved from the side of the side 12 away from the accommodating groove 11 to the side close to the accommodating groove 11 and inserted into the mounting groove 13.

[0054] It can be understood that the positioning portion 23 of the pin structure 2 is inserted toward one side of the mounting groove 13.

[0056] It can be understood that after the core unit is installed in the accommodating groove 11, the core unit can be wound around the narrowed portion 221 of the wiring portion 22 through a wire, so that the connection effect and stability of the core unit and the pin structure 2 are good.

[0057] like Figure 4 and Figure 5 As shown, in order to adapt to the pin structure 2, each installation slot 13 may be correspondingly provided with a first slot portion 133, a second slot portion 134 and a third slot portion 135, the first slot portion 133 extending along the thickness direction of the side portion 12, for the positioning section 231 to be inserted; the second slot portion 134 is for the wiring section 22 to be installed, and the third slot portion 135 is for the connection section 232 and the head end 2311 of the pin portion 21 to be installed.

[0061] A plurality of pin structures 2 are respectively installed on both sides of the two receiving grooves 11. It can be understood that the installation groove 13 is arranged corresponding to the receiving groove 11, and the installation groove 13 is correspondingly arranged on two opposite sides of the receiving groove 11. It can be understood that the network transformer 10 has two receiving grooves 11, and two core units can be respectively arranged, so that the network transformer 10 can be connected to a dual-interface RJ45 connector, or connected to two single-interface RJ45 connectors.

[0062] like Figure 2 As shown, the housing 1 may be provided with a plurality of limit grooves 14, which are arranged on the side of the housing 1 away from the mounting groove 13, that is, the limit grooves 14 are arranged on the side of the receiving groove 11, and the limit grooves 14 may be arranged one by one with the mounting grooves 13. Among them, the limit grooves 14 may be gradually inclined from the side close to the mounting groove 13 to the side close to the receiving groove 11 toward the bottom direction of the receiving groove 11, that is, the bottom surface of the limit groove 14 is inclined toward the bottom direction of the receiving groove 11, so that when the wire of the core unit is wound on the wiring part 22, the limit groove 14 plays a role in guiding and limiting the wire. Among them, the limit grooves 14 may be arranged in a staggered manner corresponding to the mounting grooves 13.

[0063] The pin structure 2 of the utility model can be firmly positioned and installed on the housing 1, and is convenient for connecting with the wire of the core unit, which brings convenience to production. The network transformer 10 can be provided with a double core unit, with a simple structure and strong versatility.
