The following will further explain the concept, specific structure and technical effects of this creation in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this creation.

It should be noted that in the description of this creation, the terms "up", "down", "left", "right", "vertical", "horizontal", "inner", "outer" and other directions or The term of positional relationship is based on the direction or positional relationship shown in the drawings, which is only for ease of description, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as Restrictions on this creation. In addition, the terms "first", "second", "third", and "fourth" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance.

Referring to FIGS. 1 to 5, which are schematic diagrams of a preferred embodiment of this creation, this creation relates to a socket electrical connector, which has an insulating body 1, a plurality of terminals 2, an ear buckle 3, and an elastic piece 4.

The insulating body 1 is an elongated plastic body. Through injection molding, the insulating body 1 is provided with an elongated slot 11 and an assembling portion 12, and the assembling portion 12 is arranged at one end of the elongated slot 11; A number of terminals 2 are provided in the strip-shaped slot 11 so that the interface card is inserted into the strip-shaped slot to be electrically conductively connected with the terminals. The ear buckle 3 is assembled on the assembling part 12 of the insulating body and can rotate relative to the insulating body around a set axis, so that the ear buckle 3 can fix or loosen the interface card inserted into the elongated slot. The ear buckle 3 is provided with a receiving groove 33, and the elastic piece 4 is assembled corresponding to the receiving groove 33 on the ear buckle. The elastic piece 4 has a first support arm 41 and a second support arm 42 connected to each other. The first support arm 41 Housed in the receiving groove 33 and connected with the ear buckle 3 by injection molding, the second support arm 42 extends out of the ear buckle and supports the assembling part 12 of the insulating body, thereby realizing the assembly of the ear buckle 3 in the assembling part of the insulating body The pre-tightening force that can rotate around the set axis relative to the insulating main body on the 12, at the same time gives the ear buckle reset power, and achieves the work of the ear buckle 3 to fix or loosen the interface card inserted into the elongated slot.

Referring to Figures 1 to 5, in this embodiment, the ear buckle 3 is provided with a positioning post 31, and the positioning post 31 is assembled and connected with a preset positioning hole 123 on the assembly part of the insulating body to achieve the ear buckle relative to the insulating body. Rotate the connection. In this embodiment, the assembling part 12 of the insulating body is further provided with a retaining slot 122 and an embedding slot 121 for fitting the ear buckle assembly. The retaining slot 122 is opened in the same direction as the elongated slot 11 to meet the requirements of the interface card. When the elongated slot 11 is inserted, the corresponding stable part of the interface card is inserted into the card slot 122, and the card slot 122 satisfies the intersection of the ear buckle 3 and the interface card. The embedding groove 121 and the locking groove 122 are perpendicular to each other, and the inner bottom of the embedding groove 121 is communicated with the locking groove 122, the ear buckle 3 is provided with a claw 32 protruding into the locking groove 122, and the claw 32 is in the With the help of the elastic piece 4, the interface card can be stably connected to the interface card, so that the interface card inserted into the elongated slot 11 can be fixed. However, when the interface card needs to be loosened, it is only necessary to press the ear buckle 3 to overcome the force of the elastic piece 4 to make the claw 32 withdraw from the clamping connection.

In this embodiment, positioning holes 123 are arranged on the left and right inner side walls opposite to the embedding groove 121, and positioning posts 31 protrude correspondingly on both sides of the ear buckle. Further, the left and right inner side walls opposite to the embedding groove 121 are respectively An introduction groove 124 is provided, and the inner bottom of the introduction groove 124 communicates with the positioning hole 123; thus, after the elastic piece 4 and the ear buckle 3 are injection molded together, the ear buckle 3 and the elastic piece 4 are assembled into the embedding groove 121 together. The pressing form forces the ear buckle 3 into the embedding groove 121, and the introduction groove 124 provides guidance and limitation. Using the expansion and contraction of the side wall of the embedding groove 121 and the introduction design of the positioning post 31, it is convenient to force the ear buckle 3 into the embedding. The positioning column 31 slides into the positioning hole 123 along the guide groove 124 to form a hinge connection, which achieves the connection of anti-backlash and relative rotation. The assembly structure is simple, easy to manufacture and assemble, low investment cost, and high production efficiency.
