[0056] Reference Figure 3 , Figure 3To draw an exploded schematic diagram of a socket electrical connector, the socket electrical connector 200 includes a socket fixed housing 21, a socket movable housing 22, and a plurality of socket terminals 23; the socket fixed housing 21 has an active space 210 and a plurality of third end positioning grooves 211 located on both sides of the active space 210; the socket movable housing 22 is located in the active space 210, and the socket movable housing 22 has a socket docking portion 221 exposed in the active space 210 and a plurality of fourth end positioning grooves 222 located on both sides of the socket docking portion 221; each socket terminal 23 has a third fixing portion 231, a fourth fixing portion 232, and a socket contact section 233 (such as Figure 4 As shown), each third fixing portion 231 is respectively positioned at each third end positioning groove, each fourth fixing portion is respectively positioned at each fourth end positioning groove, and the socket contact section is adjacent to the third fixing portion.

[0057] Reference Figure 3 The plug fixed housing 11 and the plug movable housing 12 are not in contact with each other, and the socket fixed housing 21 and the socket movable housing 22 are not in contact with each other. When the plug electrical connector 100 and the socket electrical connector 200 are assembled and matched, the plug fixed housing 11 and the plug movable housing 12 are connected by a plurality of plug terminals 13, and the plug movable housing 12 is located in the center of the plug fixed housing 11 and is in a floating state (such as Figure 5 、 Figure 6 As shown), the socket fixed housing 21 and the socket movable housing 22 are connected by a plurality of socket terminals 23, and the socket movable housing 22 is located in the center of the socket fixed housing 21 and is in a floating state (as shown Figure 5 、 Figure 6 shown).

[0058] When the plug electrical connector 100 and the receptacle electrical connector 200 are mated and matched (eg Figure 6 、 Figure 7 As shown in FIG, the movable housing 12 of the plug and the movable housing 22 of the receptacle are offset to a certain extent in the three directions of the X-axis, Y-axis, and Z-axis. Even if the movable housing 12 of the plug and the movable housing 22 of the receptacle are not aligned during assembly, they can be offset to the correct docking orientation for docking, thereby improving the overall fit between the plug electrical connector 100 and the receptacle electrical connector 200 and the freedom of adjustable docking.

[0059] The movable plug housing 12 is connected to the fixed plug housing 11 via a plurality of plug terminals 13 and has a floating property (eg Figure 5 、 Figure 6(as shown), and the plug terminals 13 have a high elastic force. The movable receptacle housing 22 is connected to the fixed receptacle housing 21 via multiple receptacle terminals 23, allowing for floating properties. The receptacle terminals 23 also have a high elastic force. When the plug electrical connector 100 and the receptacle electrical connector 200 are mated, the plug terminals 13 and receptacle terminals 23 absorb some of the stress during mating, thereby reducing stress at the soldering points (where the plug terminals 13 and receptacle terminals 23 meet the circuit board) and preventing cracks between the soldering points and the circuit board.

[0060] Reference Figure 2 The plug fixing housing 11 is a narrow and long plastic body. The plug fixing housing 11 includes a pair of first side walls and a pair of first end walls.

[0062] Reference Figure 6 Multiple plug terminals 13 are mounted on the fixed plug housing 11 and arranged in two opposing rows. Each plug terminal 13 includes an integrated plug contact segment 133 (a flat plate-shaped contact portion) and a plug soldering portion. The plug contact segment 133 is mounted on the movable plug housing 12, while the plug soldering portion extends outside the fixed plug housing 11 and is soldered to the circuit board. These multiple plug terminals 13 are used for signal transmission, with a current of 0.3 to 0.5A.

[0063] Reference Figure 6 Multiple socket terminals 23 are mounted on the fixed socket housing 21 and arranged in two opposing rows. Each socket terminal 23 includes an integrated socket contact section 233 (a protruding, resilient contact portion) and a socket soldering portion. The socket contact section 233 is mounted on the movable socket housing 22, while the socket soldering portion extends outside the fixed socket housing 21 and is soldered to a circuit board. The socket terminals 23 are used to transmit signals, with a current of 0.3 to 0.5A.

[0064] Reference Figure 4Each plug terminal 13 has a continuous bend 135 located between the first fixing portion 131 and the second fixing portion 132, which are located on different horizontal axes. The continuous bend 135 is S-shaped, with a first transition 136 adjacent to the first fixing portion 131 and a second transition 137 adjacent to the second fixing portion 132. The plug contact section 133 is secured to the movable plug housing 12 by the securing area of ​​the first fixing portion 131 at its upper end; the securing area of ​​the second fixing portion 132 is secured to the fixed plug housing 11, allowing the continuous bend 135 of the terminal to float between the fixed plug housing 11 and the movable plug housing 12.
