[0026] See also Figure 1-8 As shown, the present invention relates to a grounding plate. The grounding plate 1 includes a plate body 11, which is punched out with a plurality of assembly springs 12. In a connector, the grounding plate 1 is formed with a plurality of assembly springs 12 protruding toward a plastic body 2. The plastic body 2 is formed with a plurality of latching holes, into which the flaps can be snapped into the corresponding latching holes of the plastic body 2. At least one contact arm structure 13 is provided on one side of the plate body 11. The contact arm structure 13 is used to electrically contact the ground terminal of the connector. In this embodiment, a plurality of the contact arm structures 13 are arranged in a row along the side of the plate body 11 according to the number of ground terminals. The contact arm structures 13 include a connecting plate 131, a first contact arm 132, and a second contact arm 133. The connecting plate 131 extends forward from the plate body 11. The first and second contact arms 132, 133 extending forward from the connecting plate 131 form a clamping arm structure that respectively abuts on either side of the ground terminal. That is, the first and second contact arms 132, 133 are respectively connected to the connecting plate 131.

[0027] Furthermore, in this embodiment, the plate body 11 is a rectangular flat plate structure, wherein the contact arm structure 13 and the plate body 11 are located on the same plane.

[0028] In this embodiment, the first contact arm 132 and the second contact arm 133 are symmetrically structured. The middle portions of the first and second contact arms 132, 133 are convexly formed to form a first contact point 1321 and a second contact point 1331. The first contact point 1321 and the second contact point 1331 are aligned and face each other, and the first contact point 1321 and the second contact point 1331 respectively abut against either side of the ground terminal.

[0029] The present invention also relates to an electrical connector, comprising a ground plate 1, a plastic body 2, a first terminal group 3, and a second terminal group 4. The plastic body 2 includes a front face 21, a rear face 22, and a receiving space 23 for unidirectional insertion and installation of the ground plate 1 from the front face. The ground plate 1 is assembled in a fixed direction for unidirectional insertion from the front face, thereby uniformly assembling the same direction and avoiding structural differences among products in the same batch, which can cause trouble for customers, increase the probability of product rework, and waste manpower. The receiving space 23 extends through the front face 21 and the rear face 22. The cross-section of the receiving space 23 matches that of the ground plate 1. The front face 21 is provided with a plurality of first terminal slots 211 for inserting the first terminal group 3, and the rear face 22 is provided with a plurality of second terminal slots 221 for inserting the second terminal group 4. The ground plate 1 is disposed within the receiving space 23, the first terminal group 3 is inserted into the first terminal slots 211, and the second terminal group 4 is inserted into the second terminal slots 221. The contact arm structure 13 of the ground plate 1 is electrically connected to the ground terminals of the second terminal group 4.

[0030] In the present invention, after the grounding plate 1 is installed in the receiving space 23, the connection between the grounding plate 1 and the grounding terminal not only plays a grounding role, but also the grounding plate 1 crosses the plastic body 2, thereby increasing the contact area between the grounding plate 1 and the electrical connector and enhancing the connection strength and stability with the electrical connector.

[0031] In this embodiment, the second terminal group 4 is composed of a plurality of second terminals 41 arranged side by side. The second terminals 41 are divided into signal terminals and ground terminals. The appearance of the signal terminals and the ground terminals are basically the same. The signal terminals and the ground terminals can be distributed according to functional requirements.

[0032] The second terminal 41 includes an elastic portion 411, a connecting portion 412, and a pin portion 413. Furthermore, the elastic portion 411, connecting portion 412, and pin portion 413 are connected in sequence, with the elastic portion 411 connected to the connecting portion 412 at a right angle. The elastic portion 411 is perpendicular to the connecting portion 412, and the pin portion 413 is disposed at the other end of the connecting portion 412. The pin portion 413 is used to contact and electrically connect with other circuits. In the present invention, the first contact point 1321 and the second contact point 1331 are respectively against the two sides of the connecting portion 412 of the ground terminal.

[0033] In this embodiment, a number of assembly springs 12 are punched out on the plate body 11. The assembly springs 12 are arranged side by side along the length of the plate body 11. The assembly springs 12 protrude from the surface of the plate body 11. When the grounding plate 1 is installed in the receiving space 23, the assembly springs 12 are snapped into the receiving space 23. The assembly springs 12 are used to be snapped and fixed with the receiving space 23 to further prevent the plate body 11 from falling off. The plate body 11 is fixedly installed in the plastic body 2 by the assembly springs 12, thereby strengthening the assembly structure of the plate body 11 and the plastic body 2.

[0034] The above embodiments are merely descriptions of the preferred embodiments of the present invention and do not limit the scope of the present invention.
