[0030] It can be understood that, compared with the signal pins 13 of the existing electrical connector 1000 arranged in a staggered manner, the signal pins 13 symmetrically arranged along the second direction Y make the overall length of the electrical connector 1000 along the first direction X reduced by the length of one signal pin 13, further reducing the manufacturing cost of the electrical connector 1000.
[0031] It should be noted that the material of the isolation component 15 is a conductive material, including but not limited to copper, aluminum, or other materials that meet the conductive characteristics. In this embodiment, preferably, the material of the isolation component 15 is copper.

[0034] It should be noted that the manner in which the first isolation member 151 and the second isolation member 152 are embedded in the central seat body 11 includes but is not limited to being embedded through a groove, or when the central seat body 11 and the island seat body 12 are injection-molded, the isolation member is directly injection-molded as a part of the mold. In this embodiment, preferably, during injection molding, the isolation component 15 is placed in the mold together and acts as a part of the mold, so that the injection-molded part and the isolation member become an integral whole.
[0035] In some embodiments, please refer to Figure 4 , the island seat body 12 is provided with a first receiving groove 121 and a second receiving groove 122, and the first receiving groove 121 and the second receiving groove 122 are provided on the surface away from the direction in which the plug component 2 is inserted into the socket component 1.

Thus, the first receiving groove 121 positions the first grounding part 1512 in the plane formed by the second direction Y and the first direction X, and the second receiving groove 122 positions the second grounding part 1522 in the plane formed by the second direction Y and the first direction X, preventing the first grounding part 1512 and the second grounding part 1522 from shaking and shifting.
[0037] For the above plug socket body 21, please refer back to Figure 1 , the plug assembly 2 includes a plug socket body 21, a plurality of signal connection pins 22, and a plurality of grounding connection pins 23. The plurality of signal connection pins 22 are arranged on the plug socket body 21, and the plurality of grounding connection pins 23 are arranged on the plug socket body 21; the plug socket body 21 can be inserted into the slot, and the shape of the plug socket body 21 inserted into the slot is adapted to the shape of the slot to ensure the connection feasibility between the plug assembly 2 and the socket assembly 1, and there is a gap between the plug socket body 21 and the inner wall of the slot to facilitate the cooperation between the signal pins 13 and the signal connection pins 22, and between the grounding pins 14 and the grounding connection pins 23. When the plug assembly 2 is connected to the socket assembly 1, a signal connection pin 22 is inserted into a signal pin 13, and a grounding connection pin 23 is inserted into a grounding connection pin 23.
[0038] In some embodiments, please refer to Figure 5 , the plug socket body 21 is provided with a plugging groove 211, the central socket body 11 can be received in the plugging groove 211, and the signal connection pins 22 are attached to and / or embedded in the inner wall of the plugging groove 211, and the grounding connection pins 23 are attached to and / or embedded in the inner wall of the plugging groove 211.
[0039] In some embodiments, please refer back to Figure 1 , the socket assembly 1 includes a first docking shell 24, and the first docking shell 24 at least partially wraps the island socket body 12; the plug assembly 2 includes a second docking shell 16, and the second docking shell 16 at least partially wraps the plug socket body 21; when the plug assembly 2 is connected to the socket assembly 1, the first docking shell 24 is connected to the second docking shell 16. The first docking shell 24 and the second docking shell 16 are used to transmit current when the plug assembly 2 is connected to the socket assembly 1.
[0040] It can be understood that the number of the second docking shells 16 is two, and the two second docking shells 16 are symmetrically arranged at both ends of the plug socket body 21 along the first direction X. The ways for the second docking shell 16 to wrap the plug socket body 21 include but are not limited to groove embedding, attaching, etc. In this embodiment, preferably, the second docking shell 16 is fixed to the plug socket body 21 by groove embedding.
[0041] In some embodiments, please also refer to Figure 6 and Figure 7 , the first docking shell 24 is provided with a contact convex portion 241, and the contact convex portion 241 is located on the surface of the first docking shell 24 close to the central seat body 11. The second docking shell 16 is correspondingly provided with a contact groove 161. When the plug assembly 2 is connected to the socket assembly 1, the contact convex portion 241 is received in the contact groove 161. Through the cooperation of the contact convex portion 241 and the contact groove 161, the insertion and extraction force when the plug assembly 2 and the socket assembly 1 are connected is improved, thereby ensuring the stability of the connection between the plug assembly 2 and the socket assembly 1, and reducing the risk that the connection between the plug assembly 2 and the socket assembly 1 falls off due to shaking or other external force factors.
[0042] It can be understood that, in order to ensure the stability of the connection between the plug assembly 2 and the socket assembly 1, the number of the contact convex portions 241 is at least four. Two of the contact convex portions 241 are arranged on the surface of the first docking shell 24 close to the first side surface 111, and the two contact convex portions 241 are symmetrically distributed at both ends of the surface. The remaining two contact convex portions 241 are arranged on the surface of the first docking shell 24 close to the second side surface 112, and the two contact convex portions 241 are symmetrically distributed at both ends of the surface. Among them, the two contact convex portions 241 arranged on the surface of the first docking shell 24 close to the first side surface 111 correspond to the two contact convex portions 241 arranged on the surface of the first docking shell 24 close to the second side surface 112 to ensure the balanced force when the plug assembly 2 and the socket assembly 1 are connected.
[0043] It should be noted that, in order to ensure that the contact convex portion 241 can work normally when the plug assembly 2 and the socket assembly 1 are connected, a certain gap needs to be left between the part of the first docking shell 24 provided with the contact convex portion 241 and the island seat body 12, so that the part of the first docking shell 24 provided with the contact convex portion 241 can generate elastic deformation. In some embodiments, the above function is realized by adding an extended elastic arm and arranging the contact convex portion 241 on the elastic arm.
[0044] In some embodiments, please refer to Figure 8, along the third direction Z, the first docking shell 24 is bent and extended with a first abutting elastic arm 242. The first abutting elastic arm 242 is used to abut against the second docking shell 16 when the plug assembly 2 is connected to the socket assembly 1, so as to increase the insertion and extraction force required when the plug assembly 2 is connected to the socket assembly 1. There is a first gap 2421 between the first abutting elastic arm 242 and the island seat body 12, providing a certain space for the deformation of the first abutting elastic arm 242 when the plug assembly 2 is inserted into the socket assembly 1; in order to further increase the insertion and extraction force required when the plug assembly 2 is connected to the socket assembly 1, a abutting convex part 2422 is arranged on the surface of the first abutting elastic arm 242 close to the central seat body 11; when the plug assembly 2 is connected to the socket assembly 1, the abutting convex part 2422 abuts against the second docking shell 16, and the second docking shell 16 pushes the first abutting elastic arm 242 to move towards the direction close to the island seat body 12, and the distance of the first gap 2421 is reduced. By increasing the abutting convex part 2422, without the need to additionally increase the thickness of the first abutting elastic arm 242, the elastic deformation degree of the first abutting elastic arm 242 is increased, so as to increase the insertion and extraction force required when the plug assembly 2 is connected to the socket assembly 1 at low cost; the third direction Z, the first direction X and the second direction Y are perpendicular to each other in pairs.
[0045] It can be understood that both the plug assembly 2 and the socket assembly 1 are symmetric structures. Therefore, in order to ensure the balanced connection force between the plug assembly 2 and the socket assembly 1, the number of the first abutting elastic arms 242 is at least two, and the two first abutting elastic arms 242 are symmetrically arranged.
[0046] In some embodiments, please refer to Figure 9 , along the reverse direction of the third direction Z, the first grounding part 1512 is bent and extended with a second abutting elastic arm 1512a. There is a second gap 1512b between the second abutting elastic arm 1512a and the island seat body 12, so that the second abutting elastic arm 1512a can undergo elastic deformation; when the plug assembly 2 is connected to the socket assembly 1, the second abutting elastic arm 1512a abuts against the second docking shell 16, and the second docking shell 16 pushes the second abutting elastic arm 1512a to move towards the direction close to the island seat body 12, and the distance of the second gap 1512b is reduced; and / or, along the reverse direction of the third direction Z, the second grounding part 1522 is bent and extended with a third abutting elastic arm 1522a. There is a third gap 1522b between the third abutting elastic arm 1522a and the island seat body 12, so that the third abutting elastic arm 1522a can perform elastic deformation; specifically, when the plug assembly 2 is connected to the socket assembly 1, the third abutting elastic arm 1522a abuts against the second docking shell 16, and the second docking shell 16 pushes the third abutting elastic arm 1522a to move towards the direction close to the island seat body 12, and the distance of the third gap 1522b is reduced.
[0047] It should be noted that the number of the second abutting spring arms 1512a is two, and the two second abutting spring arms 1512a are symmetrically and spaced apart on the first grounding portion 1512. When the plug assembly 2 is connected to the socket assembly 1, one first abutting spring arm 242 is received at the spaced position between the two symmetrically arranged second abutting spring arms 1512a; the number of the third abutting spring arms 1522a is two, and the two third abutting spring arms 1522a are symmetrically and spaced apart on the second grounding portion 1522. When the plug assembly 2 is connected to the socket assembly 1, the other first abutting spring arm 242 is received at the spaced position between the two symmetrically arranged third abutting spring arms 1522a; moreover, the second abutting spring arms 1512a and the third abutting spring arms 1522a are symmetrically arranged to ensure the balanced force when the plug assembly 2 is connected to the socket assembly 1.
[0048] Furthermore, in order to enhance the connection stability between the plug assembly 2 and the socket assembly 1, in some embodiments, please refer to Figure 9 , the second abutting spring arm 1512a is provided with a first bending portion 1512c, and the second docking shell 16 is provided with a first bump 162. When the plug assembly 2 and the socket assembly 1 are connected, the first bending portion 1512c abuts against the first bump 162 in a staggered manner; the third abutting spring arm 1522a is provided with a second bending portion 1522c, and the second docking shell 16 is provided with a second bump 163. When the plug assembly 2 and the socket assembly 1 are connected, the second bending portion 1522c abuts against the second bump 163 in a staggered manner. When the plug assembly 2 needs to be detached from the socket assembly 1, the first bump 162 needs to push the first bending portion 1512c to elastically deform, and its deformation degree is greater than that of the second abutting spring arm 1512a without the first bending portion 1512c. The second bump 163 needs to push the second bending portion 1522c to elastically deform, and its deformation degree is greater than that of the third abutting spring arm 1522a without the second bending portion 1522c.
