The utility model provides an electric connector which realizes the isolation between different groups of pin assemblies. A group of pins may be one pin, 2 pins, or a greater number of pins. As shown in fig. 1 and 2, the electrical connector of the present embodiment includes a shielding shell, a pin assembly, an insulator, and a shielding plate, where the pin assembly has at least two groups. The insulator is sleeved outside the contact pin, the specific structure and the mutual connection of the insulator are in the prior art, and the scheme is not specifically repeated. The contact pin assembly, the insulator and the shielding plate are arranged in the shielding shell, the shielding plate realizes the division of the inner cavity of the shielding shell, the shielding plate and the shielding shell together form a separation cavity with the same contact pin group number, and the mutual isolation of the contact pins of different groups is realized through the separation cavity.

The number of the shielding plates and the arrangement structure of the shielding plates and the shielding shell can be realized by adopting various structures according to different electric connector types, pin structures and pin group numbers. The shielding plate and the shielding shell are used for realizing shielding of adjacent groups of pins, enhancing the full shielding, improving the impedance performance of the electric connector and greatly improving the transmission performance of the electric connector.

The shielding shell can be of an integral structure or can be formed by two parts as shown in fig. 1. As shown in fig. 1, the shield case includes a first case structure 11 having a shielding function and a second case structure 12 connected to the first case structure 11;

The first housing structure 11 is provided with a jack for leading out pins. The side wall of one end of the jack is provided with a first slot structure 111 for fixing the shielding plate.

Wherein, according to the structure setting of contact pin, jack and contact pin match. If the contact pin is in a strip shape, the jack can be arranged as a straight through hole structure. If the pin is L-shaped, the jack may be an open structure in which one end of the L-shaped pin is led out on the basis of the through hole, as shown in fig. 3.

The second housing structure 12 forms a base, and the first housing structure 11 is a shielding structure, and both can be realized by adopting various structures. Illustratively, as shown in fig. 3, a second boss 113 is provided on the first housing structure 11; the second housing structure 12 is provided with a second groove 121, and the second boss 113 is clamped in the second groove 121, so that the first housing structure 11 and the second housing structure 12 are fixedly connected. In order to enhance the connection stability of the two, the second boss 113 and the second groove 121 may be provided in plurality and uniformly distributed around.

The connection between the shielding plate and the housing can also be made in a variety of ways, in order to enhance the connection stability and facilitate the assembly of the electrical connector, the two being connected by means of a plug-in connection. Illustratively, a first groove is disposed on the first socket structure; as shown in fig. 7 and 8, the shielding plate is provided with a barb structure 21 for being placed in the first groove and a first boss 22 placed in a place of the first slot structure other than the first groove. The barb structure 21 is a barb piece structure.

In order to improve the stability of the fixation of the insulator, the side wall of the jack is provided with a second slot structure 112, and the insulator 3 is provided with a convex rib 31 for being inserted into the second slot structure.

Specifically, as shown in fig. 1 and 2, in this embodiment, the pin assembly has 4 groups of pins, each group of pins has 2 pins, and the pins take an L-shape as an example to describe a specific structure of the electrical connector. Correspondingly, in order to facilitate the installation of the pin assembly, the jack can be as shown in fig. 3, one end side wall is arranged to be in an open structure on the basis of the through hole,

The 4 sets of pins 4 then require 4 compartments. The shielding plates are arranged in 2, and comprise a first shielding plate and a second shielding plate. One end of the first housing structure 11, i.e. the open structure thereof, is provided with an isolating protrusion structure 13 arranged in the middle of the first and second shield plates simultaneously. The 4 faces of the first housing structure 11, the protruding structure 13 and the first and second shielding plates constitute 4 compartments.
