DETAILED DESCRIPTION

[0026] See also Figure 1 and Figure 2, which shows an embodiment of the present invention's insulation structure-outer-type upright electrical connector, configured with a circuit board. This embodiment of the insulation structure-outer-type upright electrical connector 1 includes an insulation structure 10, a plurality of terminals 20, a metal housing 30, and a metal separator 40. The plurality of terminals 20 are coupled to the insulation structure 10 and arranged in two parallel terminal rows. The metal separator 40 is disposed between the two terminal rows and coupled to the insulation structure 10. The metal housing 30 is positioned on the insulation structure 10. The insulation structure 10 and the metal housing 30 are positioned on the circuit board P, and the terminals 20 are soldered to the circuit board P. Each terminal 20 includes a mating portion 20a, a fixing portion 20b, and a soldering portion 20c.

[0027] See also Figure 3 and Figure 4 The insulating structure 10 includes a base 11, a tongue 12, two limiting walls 13, and an extension 14. The two limiting walls 13 and the extension 14 are disposed on the base 11, with the extension 14 located between the two limiting walls 13. The base 11 is a rectangular body. One end of the extension 14 is connected to the middle portion of the base 11 and extends in a predetermined direction. The tongue 12 is disposed at the front end of the extension 14. The tongue 12 has an upper surface 121 and a lower surface 122. The mating portion 20a of the terminal 20 is disposed on the upper surface 121 and the lower surface 122 to facilitate contact with the terminal of the opposing electrical connector.

[0028] Two limiting walls 13 are disposed on opposite sides of the base 11. Each limiting wall 13 includes a first limiting portion 131 and two second limiting portions 132. The two second limiting portions 132 are connected to opposite sides of the first limiting portion 131 and at least partially perpendicular to the first limiting portion 131. The surfaces of the first limiting portion 131 and the second limiting portion 132 on the side closest to the metal housing 30 connect to form an arcuate surface 1311. The surfaces of the first limiting portion 131 and the second limiting portion 132 on the side away from the metal housing 30 form two perpendicular flat surfaces 1312. The arcuate surface 1311 matches the shape of the metal housing 30.

[0029] The fixing portion 20b of the terminal 20 is coupled to the base 11 of the insulating structure 10, the mating portion 20a of the terminal 20 is disposed on the tongue 12, and the soldering portion 20c of the terminal 20 protrudes from the base 11 and is soldered to the circuit board P. A metal spacer 40 is disposed between the two terminal rows to provide electromagnetic shielding.

[0030] The metal housing 30 is mounted on the base 11 of the insulating structure 10 and surrounds the tongue plate 12 to form a docking space S. One end of the metal housing 30 forms a pair of ports 31 for receiving a pair of handheld electrical connectors. In this embodiment, the metal housing 30 is formed into a cylindrical structure and includes a top wall 32, a bottom wall 33 disposed opposite the top wall 32, and two opposing side walls 34 and 35. The top wall 32 corresponds to the upper surface 121 of the tongue plate 12, and the bottom wall 33 corresponds to the lower surface 122 of the tongue plate 12.

[0031] The first limiting portion 131 of the limiting wall 13 of the insulating structure 10 abuts against the outer surfaces of the first side wall 34 and the second side wall 35 of the metal shell 30, and the arc surface 1311 at the connection between the second limiting portion 132 of the limiting wall 13 and the first limiting portion 131 abuts against the connection between the top wall 32 and the first side wall 34 or the second side wall 35, and the arc surface 1311 at the connection between the other second limiting portion 132 and the first limiting portion 131 abuts against the connection between the bottom wall 33 and the first side wall 34 or the second side wall 35.

[0032] The first limiting portions 131 of the two limiting walls 13 clamp the metal housing 30 left and right, thereby limiting the metal housing 30 in a first direction L1. The second limiting portions 132 of the two limiting walls 13 clamp the metal housing 30 up and down, thereby limiting the metal housing 30 in a second direction L2. The first direction L1 and the second direction L2 are perpendicular to each other, and both the first direction L1 and the second direction L2 are perpendicular to the extension direction of the tongue plate 12.

[0033] like Figure 7 As shown, each limiting wall 13 has a locking protrusion 133, which protrudes from the inner surface of the limiting wall 13 toward the tongue plate 12 and is disposed on the first limiting portion 131. Figure 2 、 Figure 5 、 Figure 6 and Figure 7 The metal housing 30 has a pair of engaging holes 36. Engaging protrusions 133 engage with the engaging holes 36 and abut against the edges of the engaging holes 36, causing the limiting wall 13 to limit the metal housing 30 in a third direction L3. The third direction L3 is parallel to the extension direction of the tongue plate 12. That is, the third direction L3 is perpendicular to the first direction L1 and the second direction L2. Thus, the limiting wall 13 limits the metal housing 30 in three mutually perpendicular directions, forming a three-dimensional limit for the metal housing 30, ensuring that the metal housing 30 is completely positioned within the insulating structure 10.

[0034] See also Figure 5 、 Figure 9 and Figure 10The metal housing 30 further includes four retaining members 37. Two retaining members 37 protrude from the top wall 32 into the interior of the metal housing 30, and the other two retaining members 37 protrude from the bottom wall 33 into the interior of the metal housing 30. Each retaining member 37 has a retaining surface 371 on a side proximal to the docking port 31. In this embodiment, the retaining surface 371 is inclined relative to the top wall 32 or bottom wall 33. When a pair of handheld electrical connectors C are inserted into the docking space S within the metal housing 30, the front ends of the handheld electrical connectors C abut against the retaining surfaces 371 of the retaining members 37, forming a docking stop.

[0035] See also Figure 10 The insulating structure 10 further includes a plurality of positioning posts 15 . The plurality of positioning posts 15 are disposed on a side of the base 11 away from the tongue plate 12 . The plurality of positioning posts 15 are inserted into the positioning holes P1 of the circuit board P. The insulating structure 10 of this embodiment has three positioning posts 15 .

[0036] The metal housing 30 further includes a plurality of positioning pins 38 . The plurality of positioning pins 38 are disposed on the edge of the rear end of the metal housing 30 and extend rearward and pass through the positioning slots P2 of the circuit board P for positioning.

[0037] The insulating structure outsourcing upright electrical connector of the present invention uses the limiting walls of the insulating structure to abut against the outer surfaces of the first side and the second side of the metal shell, so that the metal shell is limited in the first direction and the second direction. In addition, the pair of limiting walls act as a stop for the metal shell, which can strengthen the positioning structure and make the metal shell less likely to shift or fall off due to improper force applied by the user when plugging and unplugging.
