More specifically, the elastic clamping piece 113 extends obliquely forward from the fixing portion 112 and extends inward to form a main body. The contact point 1132 is then folded back and then extended obliquely outward to be connected to the port portion 115. Viewed from a top view, the resilient clamping tab 113 has an obtuse angle of approximately 150 degrees.

Each of the contact arms 111 of the present embodiment includes a pair of extension portions 117, so that the socket terminals 11 have two pairs of extension portions 117 respectively located between the pair of elastic clamping pieces 113. In other words, as shown in FIG. 6, the pair of elastic holding pieces 113 are opposed to each other, wherein the pair of extending portions 117 are located on both sides of one elastic holding piece 113, and the other pair of extending portions 117 are located on the other elastic holding piece. On both sides of 113. Each of the extending portions 117 extends rearward from the one end of the port portion 115 in the longitudinal direction. A portion of the extension 117 is bent inwardly to form a pair of contact points 1172.

Referring to FIG. 4, the extension portion 117 of the present embodiment extends beyond the main contact point 1132, that is, the length of the extension portion 117 beyond the port portion 115 is greater than the distance from the main contact point 1132 to the port portion 115. Further, the distance from the sub contact point 1172 of the extension portion 117 to the port portion 115 is greater than the distance from the main contact point 1132 to the port portion 115. That is, the secondary contact 1172 is further from the port portion 115 than the primary contact 1132.

When the plug terminal 21 is inserted into the socket terminal 11, the tapered portion of the front end of the plug terminal 21 first contacts the secondary contact point 1172, and then the columnar portion of the rear portion of the plug terminal 21 contacts the main contact point 1132. When the plug terminal 21 is pulled outward to leave the receptacle terminal 11, the plug terminal 21 remains in contact with the main contact 1132 after it leaves the secondary contact 1172.

Please refer to FIG. 6 and FIG. 7. FIG. 6 is a front view of the socket terminal of the present invention, and FIG. 7 is a front view of the plug terminal after being inserted into the socket terminal. Each port portion 115 of this embodiment has an outer frame wall 1151 and a pair of inner folded walls 1152 which are bent inwardly from both sides of the outer frame wall 1151. The contact arm 111 has a pair of extensions 117 each connected to a pair of inner fold walls 1152. As shown in FIG. 7, the angle between the inner folded wall 1152 and the outer frame wall 1151 is substantially at a right angle. The two port portions 115 have a square shape.

The distance W2 between the pair of main contacts 1132 is smaller than the side length of the plug terminal 21, that is, when the plug terminal 21 is inserted into the socket terminal 11, it can be determined that the two main contacts 1132 are in contact. The gap W1 between the pair of sub contact points 1172 of each of the port portions 115 is smaller than the side length of the plug terminal 21. That is, when the plug terminal 21 is inserted into the socket terminal 11, it can be determined to contact the pair of sub contact points 1172.

The feature and function of the present invention is that each socket terminal 11 has a pair of contact arms 111, and the same contact arm 111 has a main contact point 1132 and two sub-contact points 1172. In other words, each receptacle terminal 11 has six contact points. When the plug terminal 21 is inserted or removed from the socket terminal 11, the stability of the electrical contact can be increased. In addition, even if there is an arc discharge to form a residue at one of the contact points, the other contact points can normally conduct power. With the above arrangement, the present invention can increase the stability of the conduction of the socket terminal 11 and avoid the problem of poor conduction due to the arc, thereby improving the service life of the socket terminal 11 and the socket connector.

It should be noted that the words "roughly" in this case are used to modify any slightly variable relationship, such as a slight inconsistency due to factors such as processing tolerances, but such minor changes do not change their nature.
