[0054] Example 1
[0055] Please refer to Figures 1-9 This embodiment provides a socket, including: an insulating colloid 1 and metal terminals 2; the metal terminals 2 are disposed on the insulating colloid 1 and are used for electrical connection of a plug (terminal). Specifically, the metal terminals 2 include: a fixed end and a contact end; wherein, the fixed end of the metal terminals 2 is snapped onto the flange 11 on the front side of the insulating colloid 1. The contact end is provided with a spring arm for electrical contact, the spring arm being a metal arm with a certain elasticity; the metal arm can be a single spring arm or a double spring arm. The metal terminals 2 are arranged in pairs and multiple pairs are provided; among the multiple pairs of metal terminals 2, at least one pair of metal terminals 2 has an anti-collision inner guide connecting arm 212 and / or an anti-collision outer guide connecting arm 213 on its contact end. The paired metal terminals 2 are designed to be centrally symmetrical, with the center of rotation being the center of the insulating colloid 1. That is, in the paired metal terminals 2, one metal terminal 2 and the other metal terminal 2 are centrally symmetrical about the center of the insulating colloid 1 (which is the center of rotation). Central symmetry means that when a pattern is rotated 180 degrees, the resulting new pattern has a special relationship with the original pattern; that is, the new pattern and the original pattern are centrally symmetrical about a certain point (usually the center of rotation). Furthermore, the contact ends of the paired metal terminals 2 extend towards each other and are positioned opposite each other, with the connecting line between the two metal terminals 2 passing through the center of rotation. To achieve electrical isolation between the metal terminals 2, a gap is provided between adjacent metal terminals 2. Similarly, it can be understood that the presence of a portion of the insulating colloid 1 between the paired metal terminals 2 naturally provides isolation, especially for the contact ends / spring arms.
[0056] in, Figures 3-9 Seven different implementations of metal terminals 2 with different structural features are shown, with multiple pairs of metal terminals 2 arranged diagonally. These are described in detail below.
[0057] like Figure 2 , Figures 3-9In one embodiment shown, the flange 11 preferably forms a ring on the front side of the insulating colloid 1 for mounting and fixing multiple pairs of metal terminals 2. Further, the metal terminals 2 include: two paired first metal terminals 21 and two paired third metal terminals 23; similarly, two second metal terminals 22 are provided in pairs; the second metal terminals 22 are located between the first metal terminals 21 and the third metal terminals 23. The first metal terminals 21 and the third metal terminals 23 serve as guides and fixers, i.e., they function to guide the insertion and fixation of the plug terminals. Furthermore, the guiding and fixing functions of the first metal terminals 21 and the third metal terminals 23 are also reflected in the fact that the first metal terminals 21 and the third metal terminals 23 cooperate with the flange 11 and are fixed to the flange under the guidance of the snap-fit grooves formed by the first metal terminals 21 and the third metal terminals 23 themselves. Preferably, at least one pair of metal terminals 2 is symmetrical about the central axis of the insulating colloid 1. Specifically... Figures 3-9 In the middle, the two second metal terminals 22 are arranged symmetrically.
[0058] like Figures 3-9 In one embodiment shown, the first metal terminal 21 is provided with a first single spring arm 211; the second metal terminal 22 is provided with a second single spring arm 221; and the third metal terminal 23 is provided with a third single spring arm 232 (e.g., ...). Figure 4 , Figure 7 , Figure 8 ) or double spring arm 231 (such as Figure 3 , Figure 5 , Figure 6 , Figure 9 The double elastic arm 231 is used to increase electrical contact performance. A single elastic arm can be understood as a single elastic contact arm, while the double elastic arm 231 consists of two single elastic arms connected side-by-side. For example... Figures 3-9 The embodiments shown illustrate various combinations of dual spring arms 231 and single spring arms, as detailed in the accompanying drawings; other combinations are also possible.
[0059] Similarly, such as Figure 3 , Figure 5 , Figure 9 In one embodiment shown, the width of the first single spring arm 211 is greater than the width of the second single spring arm 221 and / or the third single spring arm 232, especially at the contact portion. The widened first single spring arm 211 is used to improve electrical contact performance, and the contact performance of the first single spring arm 211 is better than that of the second single spring arm 221 and / or the third single spring arm 232.
[0060] like Figure 1In one embodiment shown, the insulating colloid 1 has notches 3 corresponding to the first single elastic arm 211, the second single elastic arm 221, the third single elastic arm 232, and the double elastic arm 231. The first single elastic arm 211, the second single elastic arm 221, the third single elastic arm 232, and the double elastic arm 231 may undergo elastic deformation when in electrical contact, and the notches 3 are used to provide the space required for elastic change.
[0061] like Figures 3-9 In one embodiment shown, the contact end of the first metal terminal 21 is provided with an inner anti-collision guide connecting arm 212 and / or an outer anti-collision guide connecting arm 213. Here, "inner" and "outer" are directional terms; the inner anti-collision guide connecting arm 212 faces inward and is closer to the rotation center; the outer anti-collision guide connecting arm 213 faces outward and is farther from the rotation center. The inner anti-collision guide connecting arm 212 and the outer anti-collision guide connecting arm 213 can be configured as a separate structure (e.g., ...). Figure 6 , Figure 7 , Figure 9 It can also be set as a whole (e.g.) Figure 3 , Figure 4 , Figure 5 , Figure 8 The contact end of the third metal terminal 23 is provided with an anti-collision outer guide connecting arm 213. Further, such as... Figures 5-9 As shown, when the first metal terminal 21 is provided with an anti-collision outer guide connecting arm 213, and the third metal terminal 23 is also provided with an anti-collision outer guide connecting arm 213, the two anti-collision outer guide connecting arms 213 are in a parallel state, separated in the middle, and are of a split structure; while Figure 3 , Figure 4 The outer anti-collision guide connecting arm 213 of the first metal terminal 21 shown is a single integral structure without any separation in the middle. The insulating colloid 1 has a boss 12 for supporting the inner anti-collision guide connecting arm 212; the inner anti-collision guide connecting arm 212 and its tip can be embedded in the boss 12. Bottom connecting arms 24 are provided on both the inner and outer anti-collision guide connecting arms 212 and 213, and are fixed to the bottom of the insulating colloid 1. Preferably, the bottom connecting arm 24 is embedded in the bottom of the insulating colloid 1, and its tip can be embedded in the bottom.
[0062] like Figure 3 , Figure 5 , Figure 6 , Figure 9 In one embodiment shown, the inner anti-collision guide connecting arm 212 is integrally formed on the fixed end of the first metal terminal 21 by bending; the outer anti-collision guide connecting arm 213 is integrally formed on the fixed end of the third metal terminal 23 by bending.
[0063] like Figure 4 , Figure 7 , Figure 8In one embodiment shown, the inner anti-collision guide connecting arm 212 is integrally formed on the fixed end of the first metal terminal 21 by a stretching method. The inner anti-collision guide connecting arm 212, formed by a stretching method, has a stable structure, high strength, and high rigidity, resulting in better anti-collision performance when the terminals contact during plug-socket connection, and also better guiding and fixing of the plug terminals. The outer anti-collision guide connecting arm 213 is integrally formed on the fixed end of the third metal terminal 23 by a bending method. Furthermore, as... Figure 10 As shown, the inner corner, outer corner and flange transition of metal terminal 2 also adopt the stretching process. A in the figure is the stretching process part. By adopting the stretching process, metal terminal 2 has higher strength and can achieve a more wear-resistant effect.
[0064] In this invention, the multi-conductive contact design formed by multiple pairs of metal terminals ensures uniform current distribution and reduces socket temperature rise. Specifically, by introducing multiple pairs of metal terminals 2, multiple single and double spring arms 231, the current conduction path in the socket is more dispersed, which helps to evenly distribute the current and reduce heat generation in the wires and socket. This is especially important for connecting high-power devices, such as electric heaters or power tools. When current passes through the socket, a certain resistance may be generated, causing the socket to heat up. The multi-conductive contact design can reduce the current density at each contact, reduce contact heating, and improve the safety and reliability of the socket.

[0066] This embodiment provides a connector, including a plug and a socket as described in any of the above embodiments; the plug and socket mate, and an electrical connection is formed after the plug and socket are inserted.
[0067] The connector of this invention features high electrical transmission efficiency and reliable connection. Specifically, the plug-socket connection establishes an electrical connection, which helps improve electrical transmission efficiency and reduce resistance and energy loss; the plug-socket connection also establishes a stable and reliable electrical connection, reducing the risk of disconnection and interference during connection.
[0068] Example 3

[0070] In one embodiment, the electronic device further includes a communication interface (such as a Type-C interface) electrically connected to a connector.
