Anti-interference 5G sockets, connectors and electronic devices

Abstract

This invention provides an anti-interference 5G socket, connector, and electronic device, solving the problem in existing technologies where the soldered pins on the plug easily cause wear on the socket surface when the plug is connected to the socket. Along the width direction of the socket, the distance between the two fixing portions is greater than the distance between the two oppositely arranged receiving portions, and the distance between the two oppositely arranged receiving portions is greater than the distance between the two oppositely arranged first guide portions. The fixing portions, receiving portions, and first guide portions of the anti-interference 5G socket, connector, and electronic device provided by this invention form a stepped structure. When the socket is connected to the plug, the soldered pins of the plug are located within this stepped structure and do not contact the socket, effectively preventing the soldered pins from wearing down the socket and making the signal transmission of the conductive terminals more stable.

Description

Technical Field

[0001] This invention belongs to the field of board-to-board connector technology, specifically relating to an anti-interference 5G socket, connector, and electronic device. Background Technology

[0002] Board-to-board connectors (BTBs) facilitate electrical connections and signal transmission between devices, components, and systems, and are essential components for forming a complete system. Currently, BTBs are widely used in various electronic products. A BTB connector is used to electrically connect two parallel circuit boards and typically consists of mating plug and socket connectors. Both the plug and socket connectors include an insulating body and conductive terminals. The insulating body primarily serves to insulate and position the conductive terminals, while the conductive terminals primarily provide conductivity.

[0003] The prior art discloses a board-to-board connector (CN201910535154.3). The connector's end wall reinforcement includes an end wall outer wall shielding portion covering the outer wall surface of the end wall, an extension portion extending laterally from both ends of the end wall outer wall shielding portion into an insulating body, and a soldering pin extending from the end of the extension portion out of the insulating body. The extension portion is embedded in the side wall of the insulating body. The side wall reinforcement includes a side wall outer wall shielding portion covering the outer wall surface of the side wall. There is a gap between the lower side of the side wall outer wall shielding portion and the soldering pin, and it is filled with plastic from the insulating body. For the aforementioned plug connector, its soldering pin extends out of the insulating body. Accordingly, when the plug connector is mated with the socket connector, the soldering pin is in close contact with the surface of the socket connector or has only a small gap. Therefore, during use, the soldering pin on the plug connector is prone to wear on the surface of the socket connector. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an anti-interference 5G socket, connector and electronic device to solve the problem in the prior art that the solder pins on the plug are prone to wear on the surface of the socket when the plug and socket are connected.

[0005] The technical solution adopted in this invention is as follows:

[0006] In a first aspect, the present invention provides an anti-interference 5G socket, which connects with a docking body, comprising:

[0007] Socket insulator;

[0008] Multiple socket conductive terminals are arranged along the length of the socket insulator;

[0009] Two island reinforcement fasteners are provided on the socket insulator on both sides of the socket conductive terminal along the length direction of the socket, and are used to limit the docking body. Each of the two island reinforcement fasteners has at least two elastic arms that are arranged opposite to each other along the width direction of the socket.

[0010] A signal shielding frame is sleeved on the socket insulator, the signal shielding frame is arranged around the plurality of socket conductive terminals, and has a receiving portion corresponding to each of the elastic arms, a fixing portion disposed between the two elastic arms on this side along the length direction of the socket, and a first inlet portion disposed outside the two elastic arms on this side along the length direction of the socket.

[0011] Wherein, along the width direction of the socket, the distance between the two fixing parts is greater than the distance between the two oppositely arranged receiving parts, and the distance between the two oppositely arranged receiving parts is greater than the distance between the two oppositely arranged first inlet parts.

[0012] As a preferred embodiment of the aforementioned anti-interference 5G socket, the socket insulator is provided with a receiving fitting portion, a fixing fitting portion, and a first guiding fitting portion, which are respectively corresponding to the receiving portion, the fixing portion, and the first guiding portion. The receiving fitting portion, the fixing fitting portion, and the first guiding fitting portion are recessed structures, and the receiving portion, the fixing portion, and the first guiding portion are respectively embedded in the receiving fitting portion, the fixing fitting portion, and the first guiding fitting portion.

[0013] As a preferred embodiment of the aforementioned anti-interference 5G socket, the socket conductive terminals are in two sets, each set including multiple socket conductive terminals arranged along the length of the socket. The two sets of socket conductive terminals are arranged opposite each other along the width of the socket. The socket insulator has a hollow socket conductive terminal mounting part, and the two sets of socket conductive terminals are embedded in the socket conductive terminal mounting part. Each socket conductive terminal includes a fixed arm fixed to the socket insulator. One side of the fixed arm has a welding arm extending outward from the socket, and the opposite side of the fixed arm has a U-shaped receiving arm located inside the socket. The opposite side of the receiving arm has an elastic arm that can elastically displace along the width of the socket.

[0014] As a preferred embodiment of the above-mentioned anti-interference 5G socket, the width of each group of the socket conductive terminals arranged in the length direction of the socket is less than the distance between the two receiving portions on that side; along the width direction of the socket, the width between the two fixed arms of the two conductive terminals correspondingly arranged in the two groups of socket conductive terminals is less than the distance between the two fixed portions.

[0015] As a preferred embodiment of the above-mentioned anti-interference 5G socket, each of the socket conductive terminals has a fixed arm including a first arm, a second arm and a third arm located on opposite sides of the first arm along the width direction of the socket, the second arm being connected to the welding arm, the third arm being connected to the receiving arm, and the first arm, the second arm and the third arm forming an inverted U-shaped structure, which is embedded in the socket conductive terminal mounting part correspondingly provided on the socket insulator;

[0016] Along the length of the socket, for the fixed arm portion, the width of the second arm is greater than the width of the first arm, and the width of the third arm is greater than the width of the second arm; for the socket conductive terminal mounting portion, the width of the corresponding portion of the second arm is greater than the width of the corresponding portion of the first arm, and the width of the corresponding portion of the third arm is greater than the width of the corresponding portion of the second arm.

[0017] As a preferred embodiment of the above-mentioned anti-interference 5G socket, the second arm abuts against the corresponding portion of the second arm on the conductive terminal mounting part of the socket, the width of the first arm is smaller than the width of the corresponding portion of the first arm on the conductive terminal mounting part of the socket, and the width of the third arm is smaller than the width of the corresponding portion of the third arm on the conductive terminal mounting part of the socket.

[0018] As a preferred embodiment of the aforementioned anti-interference 5G socket, a blocking portion is further provided on the socket insulator between the adjacent receiving and fitting portions and the first guiding and fitting portions. The blocking portion at least partially covers the cross-section of the first guiding portion exposed relative to the receiving portion in the socket width direction.

[0019] As a preferred embodiment of the aforementioned anti-interference 5G socket, a barrier plate is provided between the two central island reinforcing fasteners to connect the two. The barrier plate is located between the two sets of socket conductive terminals. In the length direction of the socket, the width of the barrier plate is greater than the width of any set of socket conductive terminals, and in the thickness direction of the socket, the width of the barrier plate is greater than the width of any one of the socket conductive terminals.

[0020] In a second aspect, the present invention provides a connector, comprising:

[0021] The socket is any of the above-described anti-interference 5G sockets;

[0022] The plug is connected to the socket.

[0023] Thirdly, the present invention provides an electronic device, including any of the anti-interference 5G sockets described above or the aforementioned electronic devices.

[0024] In summary, the beneficial effects of the present invention are as follows:

[0025] The anti-interference 5G socket, connector, and electronic device provided by this invention have a socket insulator for supporting and separating the various components of the connector, preventing electrical signal interference between the components; the socket conductive terminals are used to connect with the conductive terminals of the mating body to transmit electrical signals; the island reinforcement fastener is used to limit the mating body, preventing the mating body from being inserted too deeply and damaging the socket and the mating body; in addition, the two elastic arms on the island reinforcement fastener can generate elastic displacement, and during the process of the socket and the mating body, when the mating body acts on the elastic arms, the elastic arms have a buffering effect on the mating body, which can effectively protect the mating body; a signal shielding frame is arranged around multiple socket conductive terminals, and the signal shielding frame can be grounded as a whole to shield external signals, preventing external signals from interfering with the transmission of electrical signals by the conductive terminals; the signal shielding frame has receiving portions corresponding to the elastic arms, and two receiving portions are arranged along the length of the socket. The device includes a fixing part and a first guide part outside the two elastic arms. The fixing part strengthens the signal shielding frame, and the first guide part is used to align the docking body of the connector. Along the width direction of the connector, the distance between the two fixing parts is greater than the distance between the two oppositely arranged receiving parts, and the distance between the two oppositely arranged receiving parts is greater than the distance between the two oppositely arranged first guide parts. Accordingly, a stepped structure is formed between the fixing part, the receiving part, and the first guide part. The stepped structure at the fixing part helps to install the conductive terminals of the connector, and the stepped structure at the receiving part helps to accommodate the solder feet on the docking body. When the connector is connected to the docking body, the solder feet of the docking body are located within the stepped structure and do not contact the connector. Furthermore, when soldering the solder feet, the solder is less likely to contact the connector, which can effectively prevent the solder feet from wearing down the connector and make the signal transmission of the conductive terminals more stable.

[0047] Example 1

[0048] Please see Figure 1 (a), (b) and (c) of this embodiment disclose a connector 10, which is a combined high-strength precision connector 10, mainly used in the field of communication technology, especially in the field of 5G signal transmission. It has strong anti-interference ability and can reduce electrical noise.

[0049] Specifically, the connector 10 includes a plug 200 and a socket 100. The socket 100 has a mating recess 110, and the plug 200 has a mating protrusion 210. The mating recess 110 and the mating protrusion 210 engage with each other to form the connector 10. The socket 100 has a socket conductive terminal 130, and the plug 200 has a plug conductive terminal 220. The plug conductive terminal 220 is used to connect to the circuit board of one electronic component, and the socket conductive terminal 130 is used to connect to the circuit boards of other electronic components. A portion of the socket conductive terminal 130 is located within the mating recess 110, and a portion of the plug conductive terminal 220 is located on the mating protrusion 210. When the plug 200 and socket 100 are engaged, the socket conductive terminal 130 and the plug conductive terminal 220 contact each other, achieving an electrical connection between the two electronic component circuit boards.

[0050] Please see Figure 1 and Figure 2 The insertion direction of the plug 200 relative to the socket 100 is the thickness direction Z of the socket, the arrangement direction of the conductive terminals 130 of the socket is the length direction of the socket 100, and the width direction Y, length direction X, and thickness direction Z of the socket are perpendicular to each other.

[0051] Example 2

[0052] Please see Figure 2 In (a) and (b), this embodiment discloses a combined structure socket that mates with a mating body, which is the plug of Embodiment 1. The socket 100 includes:

[0053] The socket insulator 120, made of insulating material, is used to support and separate the components of the socket 100 and prevent electrical signal interference between the components.

[0054] Multiple socket conductive terminals 130 are arranged along the length X of the socket on the socket insulator 120 for connecting with the conductive terminals of the plug to transmit electrical signals.

[0055] Two island reinforcing fasteners 140 are provided on the socket insulators 120 on both sides of the socket conductive terminals 130 along the length X of the socket. They are used to limit the plug and prevent the plug from being inserted too deeply, which would damage the socket 100 and the plug. They can also strengthen the structure of the connector. Each of the two island reinforcing fasteners 140 has at least two elastic arms 141 that are arranged opposite each other along the width Y of the socket. The elastic arms 141 have contact portions 1411 that contact the plug. The two elastic arms 141 can generate elastic displacement. During the process of the socket 100 and the plug being engaged, when the plug acts on the contact portion 1411 of the elastic arm 141, the elastic arm 141 has a buffering effect on the plug, which can effectively protect the plug and the socket 100.

[0056] A signal shielding frame 150 is fitted onto the socket insulator 120. The signal shielding frame 150 is arranged around multiple socket conductive terminals 130. The signal shielding frame 150 is grounded as a whole to shield external signals and prevent external signals from interfering with the transmission of electrical signals by the conductive terminals. It has a receiving portion 151 corresponding to each elastic arm 141, a fixing portion 152 arranged between the two elastic arms 141 on this side along the length X of the socket, and a first guide portion 153 arranged outside the two elastic arms 141 on this side along the length X of the socket. The fixing portion 152 can strengthen the signal shielding frame 150, and the first guide portion 153 is used to align the plug of the socket 100.

[0057] The central island reinforcing fastener 140 is independently installed relative to other components of the socket 100. The elastic plate 141 extends along the socket width direction Y, and the two opposing elastic arms 141 extend in directions that move away from each other. (See [link to relevant documentation]). Figure 2 In (b), the two arrows of the island reinforcement fastener 140 point in directions that are far apart from each other. Therefore, when machining the elastic arm 141 on the sheet metal, the space for the extension direction of the elastic arm 141 is unlimited and will not be obstructed by other structures. Sufficient material is available for machining the elastic arm 141, allowing for the machining of elastic arms 141 of any shape and size. This elastic arm 141 structure can adapt to the development of communication technology, especially in the 5G field, enabling the machining of connectors 10 with higher precision. Furthermore, the maximum width between the two opposing elastic arms 141 is less than the distance between the two opposing fixing parts 152, ensuring that the elastic arm 141 machined in this manner is located between the two fixing parts 152. The two fixing parts 152 can effectively protect the elastic arm 141. Additionally, the minimum width between the contact parts 1411 of the two opposing elastic arms 141 is less than the distance between the two opposing first guide parts 153. During the insertion of the plug into the socket 100, the plug is first aligned, and then the impact force of the plug is reduced, effectively protecting the socket 100 and the plug.

[0058] To facilitate understanding of the structure of socket 100, the components of socket 100 are described in further detail below:

[0059] Please see Figure 3In (a) and (b), the socket insulator 120 is provided with a receiving fitting portion 121, a fixing fitting portion 122, and a first guiding fitting portion 123, which correspond to the receiving portion 151, the fixing portion 152, and the first guiding portion 153, respectively. The receiving fitting portion 121, the fixing fitting portion 122, and the first guiding fitting portion 123 are recessed structures. The receiving portion 151, the fixing portion 152, and the first guiding portion 153 are respectively embedded in the receiving fitting portion 121, the fixing fitting portion 122, and the first guiding fitting portion 123. The signal shielding frame 150 can be better fixed on the socket insulator 120, and the connection is more stable.

[0060] Please see Figure 4 In (a) and (b), the socket insulator 120 also includes a side arm 124. The receiving fitting portion 121 and the side arm 124 are respectively located on both sides of the first guide fitting portion 123, and the side arm 124 connects the two oppositely arranged first guide fitting portions 123. The side arm 124 is arranged along the width direction Y of the socket, and the receiving fitting portion 121, the fixing fitting portion 122 and the first guide fitting portion 123 are arranged along the length direction X of the socket. The fixing fitting portion 122, the receiving fitting portion 121, the first guide fitting portion 123 and the side arm 124 are connected together to form the frame of the socket insulator 120.

[0061] The socket insulator 120 also includes a bottom wall 125, which is located on the side of the side arm 124 facing the socket conductive terminal and at the location of the fitting recess 110 of the socket 100. The bottom wall 125 has a recessed structure, and the island reinforcement fastener 140 is embedded in the recessed structure of the bottom wall 125 along the thickness direction Z of the socket, and is embedded in the side arm 124 along the length direction X of the socket from the bottom wall embedding portion. Specifically, the island reinforcement fastener 140 includes a plate-like structure plate 142. Part of the plate 142 is embedded in the bottom wall 125, and part of the structure is exposed outside the socket insulator 120. After the plug and socket are fully engaged, the plug contacts the exposed part of the plate 142. The plate 142 can limit the displacement of the plug in the plug-socket engagement direction, preventing the plug from being inserted too deeply and thus damaging the plug and socket. In addition, besides the bottom wall embedded part, the plate 142 also has a side arm embedded part. In the side arm embedded part, the plate 142 is fully embedded in the side arm 124, and the plate 142 is wrapped by the side arm 124. Here, the connection between the plate 142 and the side arm 124 is more stable, thereby making the connection between the island reinforcement fastener 140 and the socket insulator 120 more stable.

[0062] Preferably, in the side arm embedding portion of the side arm 124 embedded in the plate body 142, the plate body 142 has a central island grounding solder foot 143 that passes through the side arm 124 along the socket width direction Y and / or along the socket length direction X and extends to the outside of the socket insulator 120. The central island grounding solder foot 143 is grounded, and the central island reinforcing fastener 140 has a signal shielding function. Specifically, along the width direction Y of the socket, both ends of the plate 142 are connected to island grounding feet 143. The two island grounding feet 143 extend from the plate 142 through the inside of the socket insulator 120 to the outside of the socket insulator 120. They not only have the function of grounding, but also enhance the stability of the connection between the island reinforcing fastener 140 and the socket insulator 120 (limiting the displacement of the island reinforcing fastener 140 in the length, width and thickness directions of the socket). More preferably, along the width direction Y of the socket, the plate 142 is also connected to island grounding feet 143, which also extend to the outside of the socket insulator 120.

[0063] In another implementation, please refer to Figure 4 and Figure 5 (c) A reinforcing part 144 is also provided on the central island grounding weld foot 143. The reinforcing part 144 is embedded in the side arm 124 of the socket insulator 120. By restricting the movement of the central island reinforcing fastener 140 relative to the socket insulator 120 in the socket thickness direction Z, the connection between the central island reinforcing fastener 140 and the socket insulator 120 is strengthened. Preferably, the reinforcing part 144 includes a reinforcing plate 1441, which is connected to the central island grounding weld foot 143. The reinforcing plate 1441 is inclined relative to the central island grounding weld foot 143 at a large angle. The free end of the reinforcing plate 1441 is a hook-shaped structure processed by bending process, which is embedded in the socket insulator 120.

[0064] Please see Figure 4 and Figure 5 The socket insulator 120 has a raised central island 126 in the middle. The socket fitting recess 110 is arranged around the central island 126. The two central island reinforcing fasteners 140 arranged opposite each other have a socket part 145 at their close ends. The two socket parts 145 are fitted onto the central island 126. The side of the two socket parts 145 facing away from the central island 126 has an anti-collision part 146. The anti-collision part 146 has an arc-shaped structure, which can smoothly guide the plug 200 into the socket 100.

[0065] Specifically, please see Figure 4 as well as Figure 5In (a) and (b), the sleeve portion 145 includes a first fixing plate 1451 and a second fixing plate 1452. The first fixing plate 1451 is formed by bending the plate body 142 in the direction opposite to its gravity direction. The second fixing plate 1452 is integrally formed with the first fixing plate 1451. The second fixing plate 1452 includes a first end 14521 and a second end 14522 located at opposite ends. Notches are provided between the first end 14521 and the first fixing plate 1451, and between the second end 14522 and the first fixing plate 1451. The first end 14521 and the second end 14522 of the second fixing plate 1452 are bent in the gravity direction, so that a fixed space is formed between the first fixing plate 1451 and the second fixing plate 1452, which facilitates the fixing of the island reinforcement fastener 140 and the island 126.

[0066] Preferably, the sleeve portion 145 further includes a third fixing plate 1453, which is integrally formed with the second fixing plate 1452. The third fixing plate 1453 is inclined relative to the surface of the central island 126 and is embedded in the central island 126, making the connection between the central island 126 and the central island reinforcing fastener 140 more stable.

[0067] In another implementation, please refer to Figure 5 (c) The second fixing plate 1452 of the sleeve portion 145 has no gap between it and the first fixing plate 1451. The two are integrally formed. The first end 14521 and the second end 14522 of the second fixing plate 1452 are integrally formed with the plate body 142. The sleeve portion 145 has higher strength. Specifically, the sleeve portion 145 formed by the integral forming of the first fixing plate 1451, the second fixing plate 1452 and the plate body 142 is made by an ultra-precision micro-stretching and stretching process.

[0068] Preferably, Figure 5 As shown in (a) and (b), the island reinforcement fastener 140 can also be equipped with something like... Figure 5 The reinforcing part 144 shown in (c) has the shape and advantages as described above.

[0069] Please see Figure 2 In (a) and (b), the two elastic arms 141, which are arranged opposite each other, elastically displace in directions away from each other under the action of external force. Along the thickness direction Z of the socket, during the movement of the upper elastic arm 141, the height of the highest position of the elastic arm 141 is lower than the height of the lowest point of the receiving part 151. Accordingly, the elastic arm 141 will never come into contact with the signal shielding frame 150, and there will be no collision or wear between the two, so both can be well protected.

[0070] Further preferred, please refer to Figure 4In (a) and (b), along the width direction Y of the socket, the maximum width between the two corresponding elastic arms 141 during elastic displacement is less than the distance between the two corresponding receiving and fitting portions 121. Furthermore, along the length direction X of the socket, the maximum width of each elastic arm 141 is less than the width of its corresponding receiving and fitting portion 121. Therefore, the elastic arms 141 move within the space facing the interior of the socket 100 from the receiving and fitting portions 121, preventing collisions and wear, and providing good protection for both.

[0071] Preferably, please refer to Figure 5 (a) The elastic arm 141 includes an elastic plate 1412 and a contact portion 1411. The elastic plate 1412 is connected to the plate body 142 of the central island reinforcing fastener 140. The contact portion 1411 is located at the free end of the elastic plate 1412. The elastic plate 1412 is formed by bending the plate body 142 from bottom to top along the thickness direction Z of the socket. The contact portion 1411 of the elastic arm 141 has an arc-shaped structure. This arc-shaped structure is formed by bending the elastic plates 1412 of the two oppositely arranged elastic arms 141 in directions that are far apart from each other. The arc-shaped structure makes the connection between the elastic arm 141 and the plug more stable and reduces wear on both.

[0072] More preferably, the width of the elastic arm 141 gradually decreases in the length direction X of the socket from the part connected to the island reinforcement fastener 140 to its extended end portion, which ensures both strong elastic performance and high structural strength.

[0073] In another implementation, please refer to Figure 5 In (b) and (c), the contact portion 1411 of the elastic arm 141 is formed by bending the elastic plates 1412 of the two oppositely arranged elastic arms 141 along the direction in which they approach each other. This structure makes the maximum width of the two oppositely arranged elastic arms 141 smaller and the structure of the socket 100 more compact.

[0074] Preferably, please refer to Figure 3 In (a) and (b), two first inlet portions 153 of the signal shielding frame 150 are arranged opposite each other along the length direction X of the socket. A second inlet portion 154 is also provided between them. The second inlet portion 154 is arranged along the width direction Y of the socket. Furthermore, a third inlet portion 155 is provided at the angle between the second inlet portion 154 and the first inlet portion 153. The first inlet portion 153, the second inlet portion 154, and the third inlet portion 155 are integrally formed and are all curved surfaces, which are obtained by ultra-precision micro-stretching and extending process. Compared with the case of only having a first inlet portion 153, this embodiment provides a better blind-click insertion effect for the plug.

[0075] Example 3

[0076] This embodiment discloses an anti-interference 5G socket. Compared with the socket 100 in Embodiment 2, this embodiment has made improvements to the signal shielding frame 150 and the socket conductive terminals 130. Please refer to the following for details:

[0077] For plugs with soldering pins, the soldering pins extend beyond their insulating body. As a result, when the plug is mated with the socket, the soldering pins are either in close contact with the surface of the socket or have only a tiny gap. Therefore, during use, the soldering pins can easily wear down the surface of the socket connector.

[0078] In this embodiment, please refer to Figure 1 (a), (b), (c) and Figure 2 In (a) and (b), along the width direction Y of the socket, the distance between the two fixing parts 152 is greater than the distance between the two oppositely arranged receiving parts 151, and the distance between the two oppositely arranged receiving parts 151 is greater than the distance between the two oppositely arranged first inlet parts 153. Accordingly, a stepped structure is formed between the fixing parts 152, the receiving parts 151 and the first inlet parts 153. The stepped structure at the fixing part 152 helps to install the socket conductive terminal 130, and the stepped structure at the receiving part 151 helps to accommodate the solder feet on the plug 200. When the socket 100 is connected to the plug 200, the solder feet of the plug 200 are located in the stepped structure and do not contact the socket 100. Furthermore, when soldering the solder feet, the solder is not easy to contact the socket 100, which can effectively prevent the plug solder feet 230 from wearing down the socket 100, making the signal transmission of the conductive terminal more stable.

[0079] Preferably, please refer to Figure 3 In (a) and (b), a blocking portion 127 is also provided on the socket insulator 120 between the adjacent receiving fitting portion 121 and the first guide fitting portion 123. The blocking portion 127 at least partially covers the cross section of the first guide portion 153 exposed relative to the receiving portion 151 in the socket width direction Y. Specifically, since there are four first guide fitting portions 123, there are also four blocking portions 127, distributed at the four corners of the socket 100. The four blocking portions 127 are disposed inside the four first guide portions 153, forming a clamp on the four first guide portions 153. Accordingly, this structure can better fix the signal shielding frame 150, and the connection between the signal shielding frame 150 and the socket insulator 120 is more stable.

[0080] For the socket conductive terminal 130 on socket 100:

[0081] Please see Figure 7(a), (b), and (c) indicate that the socket conductive terminals 130 are in two sets, each set including multiple socket conductive terminals 130 arranged along the length X of the socket. The two sets of socket conductive terminals 130 are arranged opposite each other along the width Y of the socket. The socket insulator 120 has a hollow socket conductive terminal mounting portion 128, and the two sets of socket conductive terminals 130 are embedded in the socket conductive terminal mounting portion 128. Each socket conductive terminal 130 includes a fixing arm portion 131 fixed to the socket insulator 120. One side of the fixing arm portion 131 has a direction towards the socket. The externally extending welding arm 132 of the socket 100 is welded to the circuit board of the electronic component for transmitting electrical signals. On the opposite side of the fixed arm 131, there is a U-shaped receiving arm 133 located inside the socket 100. The plug conductive terminal 220 is embedded in the receiving arm 133, and the connection between the two conductive terminals is relatively stable. On the opposite side of the receiving arm 133 from the fixed arm 131, there is an elastic arm 134 that can elastically displace along the width direction Y of the socket. Under the elastic force of the elastic arm 134, the connection between the two conductive terminals is more stable.

[0082] Preferably, the width of each set of socket conductive terminals 130 arranged in the length direction X of the socket is smaller than the distance between the two receiving portions 151 on that side. That is, the width of each set of socket conductive terminals 130 is smaller than the length of the fixing portion 152. Along the width direction Y of the socket, the width between the two fixing arms 131 of the two conductive terminals correspondingly arranged in the two sets of socket conductive terminals 130 is smaller than the distance between the two fixing portions 152. This will enable the grounded fixing portion 152 to better shield the interference signals near the socket conductive terminals 130.

[0083] Preferably, each socket conductive terminal 130 has a fixing arm 131 including a first arm 1311, a second arm 1312 and a third arm 1313 located on opposite sides of the first arm 1311 along the socket width direction Y. The second arm 1312 is connected to the welding arm 132, and the third arm 1313 is connected to the receiving arm 133. The first arm 1311, the second arm 1312 and the third arm 1313 form an inverted U-shaped structure and are embedded in the corresponding socket conductive terminal mounting part 128 on the socket insulator 120.

[0084] Specifically, along the length X of the socket, for the fixed arm 131, the width of the second arm 1312 is greater than the width of the first arm 1311; for the socket conductive terminal mounting portion 128, the width of the corresponding portion of the second arm 1312 is greater than the width of the corresponding portion of the first arm 1311. Similarly, for the fixed arm 131, the width of the third arm 1313 is greater than the width of the second arm 1312; for the socket conductive terminal mounting portion 128, the width of the corresponding portion of the third arm 1313 is greater than the width of the corresponding portion of the second arm 1312. Therefore, the connection between the socket conductive terminal 130 and the socket insulator 120 is more stable.

[0085] More preferably, the second arm 1312 abuts against the corresponding portion of the second arm 1312 on the socket conductive terminal mounting part 128, which plays a role in fixing the signal terminal. The width of the first arm 1311 is smaller than the width of the corresponding portion of the first arm 1311 on the socket conductive terminal mounting part 128, and the width of the third arm 1313 is smaller than the width of the corresponding portion of the third arm 1313 on the socket conductive terminal mounting part 128. Specifically, there is a certain gap between the second arm 1312 and the third arm 1313 and the insulator, which makes the elasticity of the socket conductive terminal 130 better, the terminal can be reset, and it is easy to disassemble and assemble. If there is no gap, the socket conductive terminal 130 will scratch the plastic when it bounces, causing the socket conductive terminal 130 to fail to reset. In addition, due to the existence of the gap, the fitting accuracy between the plug conductive terminal 220 and the socket conductive terminal 130 is better, which can better correct the assembly error between the two. At the same time, the gap also has the function of heat dissipation.

[0086] Example 4

[0087] This embodiment discloses a miniature connector socket with grounding function. Compared with embodiment 3, this embodiment improves the grounding function of the signal shielding frame 150 and the island reinforcement fixing member 140, as detailed below:

[0088] Please see Figure 6 The signal shielding frame 150 is provided with a shielding frame grounding solder foot 156, which is located on one side of the central island grounding solder foot 143, and there is a welding gap 157 between the shielding frame grounding solder foot 156 and the central island grounding solder foot 143 for welding the two together.

[0089] Since the island reinforcement fixing component 140 is independently set relative to the signal shielding frame 150, the structural stability between the two is not very high. By setting the welding gap 157, the island reinforcement fixing component 140 and the signal shielding frame 150 are designed separately during connector assembly, which has the advantages of any of the sockets 100 in the aforementioned embodiments 1-3. After the connector is assembled, the island reinforcement fixing component 140 and the signal shielding frame 150 are welded together through the welding gap 157. The two can be regarded as an integral structure with high connection strength and better connector stability.

[0090] Example 5

[0091] This embodiment discloses a miniature connector socket with signal shielding function. Compared with embodiment 4, this embodiment has improved the shielding of interference signals, as detailed below:

[0092] Please see Figure 2 (b) Figure 4 (b) A barrier plate 160 is provided between the two island reinforcement fasteners 140 to connect them. The barrier plate 160 is located between the two sets of socket conductive terminals 130 and is set inside the island 126. In the socket length direction X, the width of the barrier plate 160 is greater than the width of any set of socket conductive terminals 130, and in the socket thickness direction Z, the height of the barrier plate 160 is greater than the height of any one of the socket conductive terminals 130. Accordingly, the barrier plate 160 can prevent mutual interference between the two sets of socket conductive terminals 130.

[0093] Preferably, such as Figure 4 As shown in (b), along the width Y direction of the socket, the barrier plate 160 has multiple reinforcing holes 161 penetrating the barrier plate 160. These reinforcing holes 161 are evenly distributed along the length X direction of the socket on the barrier plate 160. Correspondingly, as... Figure 7 As shown in (a), a plurality of reinforcing posts 1261 are provided on the central island 126, and the plurality of reinforcing posts 1261 pass through a plurality of reinforcing holes 161. Accordingly, the connection between the barrier plate 160 and the central island 126 is more stable.

[0094] Preferably, such as Figure 2 As shown in (b), the barrier plate 160 is provided with protrusions and recesses, which are arranged alternately along the length of the socket. The protrusions extend from the inside of the socket insulator through the insulator to the outside of the socket insulator, which can ensure the stability of the barrier plate in the thickness direction of the socket.

[0095] The protrusion is located directly below the reinforcing hole 161 and has the same number as the reinforcing hole 161. Due to the presence of the reinforcing hole 161, the overall width of the barrier plate 160 is reduced. Therefore, placing the protrusion directly below the reinforcing hole 161 ensures that the overall width of the barrier plate 160 will not be reduced. If the recess is placed directly below the reinforcing hole, the width of the barrier plate 160 will be too low, and the strength of the barrier plate 160 will be affected.

[0096] In this embodiment, the central island reinforcing fastener 140 does not have a sleeve portion 145.

[0097] In another implementation, please refer to Figure 8 To prevent the plug from damaging the socket when it is engaged, an anti-collision arm 147 is machined on the plate 142 of the central island reinforcing fastener 140. The anti-collision arm 147 has an arc-shaped structure, which can smoothly guide the plug into the socket.

[0098] The manufacturing process of anti-collision arm 147 is as follows:

[0099] First, cut a distance along the length X of the socket on the board, then cut a distance along the width Y of the socket, and finally cut another distance along the length X of the socket. Thus, the board for processing the anti-collision arm 147 is formed on the board 142.

[0100] 2. Bend the plate along the thickness direction Z of the socket at the connection of the plate 142 from bottom to top, and then bend its free end into an arc shape. At this point, the anti-collision arm 147 is completed.

[0101] More preferably, a reinforcing part 144 may also be provided on the island reinforcement fastener 140, and the shape and advantages of the reinforcing part 144 are the same as in embodiment 2.
