[0019] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0020] Please see Figures 1 to 3 As shown, this utility model discloses an electrical connector 100, including an insulator 10 and a plurality of sheet-shaped terminals 20. Each terminal 20 consists of a pair of terminal pieces 21, which are respectively inserted into terminal slots 11 from the upper and lower surfaces of the insulator 10. In this embodiment, the terminals 20 mounted on the electrical connector 100 are LGA / LGA terminals, commonly used for high-frequency signal transmission.

[0021] See Figure 1 and Figure 2As shown, the electrical connector 100 includes an insulator 10 and a plurality of terminals 20 disposed on the insulator 10. Specifically, the insulator 10 is provided with a plurality of terminal slots 11, each terminal slot 11 including a through slot 12 and limiting slots 13 located at the upper and lower ends of the through slot 12. Each terminal 20 is composed of a pair of terminal members 21, each terminal member 21 including a main body portion 212 located in the terminal slot 11, an elastic arm 211 inclined from the main body portion 212 to one side thereof, the elastic arm 211 having a contact portion 212 protruding from the insulator 10, the main body portion 212 including a base portion 2120 and a limiting portion 2121 located at the top of the base portion 2120, a fastening portion 214 being provided at the end of the main body portion 212, and wings 213 integrally extending from both sides of the limiting portion 2121, the wings 213, the fastening portion 214 and the main body portion 212 being located in the same vertical plane. A pair of terminal pieces 21 are inserted into terminal slots 11 from the upper and lower surfaces of the insulator 10, respectively. The limiting portions 2121 of the two terminal pieces 21 are located in the corresponding limiting slots 13, and the other parts of the main body 212 are located in the through slot 12. The two engaging portions 214 engage with each other. Compared with the installation method of inserting one-piece terminals in the vertical direction, especially LGA / LGA type terminals, the terminal slot needs to reserve a certain space so that the lower elastic arm can pass through when installed from top to bottom, or the upper elastic arm can pass through when installed from bottom to top. The two-piece terminals are inserted from the upper and lower surfaces of the insulator, requiring a smaller terminal slot volume. While keeping the volume of the insulator 10 unchanged, more terminals can be accommodated, improving the high-frequency signal transmission performance of the electrical connector 100.

[0022] See Figure 2 , 3 and Figure 5 As shown, in this embodiment, the two terminal pieces 21 have the same structure. The main body 212 has an opening 215 located between the limiting part 2121 and the fastening part 214. The opening 215 and the fastening part 214 are respectively located on opposite sides of the main body 212. The fastening part 214 is a hook structure formed by half-openings 216, and the hook has a guiding arc 217. Preferably, both the opening 215 and the half-openings 216 are open towards the side of the main body 212 away from the hook, and the half-openings 216 are simultaneously open towards the side of the main body 212 away from the hook. The body portion 212 of the other terminal piece is open, so that when a pair of terminal pieces 21 are inserted into the terminal slot 11 from the upper and lower surfaces of the insulator 10 respectively, the hook of the lower terminal piece 21 enters the half-opening 216 of the upper terminal piece 21 through the opening of the half-opening 216 of the upper terminal piece 21, and at the same time, the hook of the upper terminal piece 21 enters the half-opening 216 of the lower terminal piece 21 through the opening of the half-opening 216 of the lower terminal piece 21, and the two terminal pieces 21 are engaged with each other in the up and down direction.

[0023] In this invention, to facilitate the smooth engagement of the two hooks into the through groove 12 during installation of the two end pieces 21, the wing 213 has a chamfer 2131, and the limiting groove 13 has a chamfered surface 1121 that matches the chamfer 2131. When installing the terminal 20, a pair of terminal pieces 21 enter from outside the insulator 10, and their hooks interfere with each other. It should be noted that in this invention, after the two end pieces 21 are engaged, the hooks of the two end pieces 21 partially overlap along the width direction of the terminal 20, so that the hooks of the two end pieces 21 abut against each other in the vertical direction. To ensure smooth installation into the terminal slot even when the two hooks overlap in the width direction of the terminal 20, each hook has a notch 218 on its outer edge at the top, forming a relief groove 210 with the through groove 12. When the two hooks are at the same horizontal height, they deform within the relief groove 210. Thus, the guide arc 217 guides the hooks to the semi-openings 216 of both sides. As the top surface of the hooks applies further force to the other's main body 212, the opening 215 begins to contract until the hooks are fully engaged in the other's semi-opening 216. The opening 215 then recovers, and the top surface of the semi-opening 216 abuts against the top surface of the other hook, completing the engagement of the terminal 21. Preferably, the outer edge of the hook of the terminal 21 is flush with the outer edge of the opening 215 of the other terminal 21, that is, the outer edge of the hook and the outer edge of the opening 215 of the other terminal 21 are located in the same vertical plane along the thickness direction of the main body 212 of the terminal 21. When the terminal piece 21 is pushed along the inner wall of the through groove 12, the top surface of the hook can always be kept in the same straight line with the opening 215, which facilitates the opening 215 to open and close and improves the elastic deformation performance of the terminal piece 21.

[0024] See Figures 4 to 6 As shown, the through groove 12 includes a first inner wall surface 121 and a second inner wall surface 122 facing each other. Further, a rib 123 protrudes from the first inner wall surface 121 into the through groove 12, abutting against the terminal 20, so that the terminal 20 remains attached to and held in place by the second inner wall surface 122. Specifically, the insulator 10 has a guide surface 15 near its upper and lower surfaces. The guide surface 15 is connected to one of the first inner wall surfaces 121 and is connected to the chamfered surface 1121. The rib 123 has inclined surfaces 1231 at both ends, which protrude from the first inner wall surface 121 to the bottom of the guide surface 15. When the terminal 21 is inserted, it snaps... The mating part 214 first abuts against the guide surface 15 and the inclined surface 1231, and then along the inclined surface 123, the main body part 212 fits against the second inner wall surface 122. The chamfer 2131 of the wing part 213 interferes with the chamfer surface 1121. When viewed from the top and bottom, the projection of one of the first inner wall surfaces 121 and the contact part 211 overlaps with each other. In this way, the distance between adjacent terminals 20 is kept within the range of less than 0.5 mm. Preferably, there is a gap 14 between the chamfer 2131 and the chamfer surface 1121, so that the terminal 20 can float slightly, improving the adaptability of LGA / LGA terminals in different insertion and removal environments.

Any equivalent changes to the technical solution of the present utility model made by those skilled in the art after reading the present utility model specification shall be covered by the claims of the present utility model.
