Description

Technical Field

[0001] The present invention belongs to the technical field of board-to-board connectors, and particularly relates to a combined structure socket, a connector, and an electronic device. Background Art

[0002] Board-to-board connectors are used for electrical connection and signal transmission between devices, components, and systems, and are essential basic components for forming a complete system. Currently, board-to-board connectors are widely used in various electronic products. A board-to-board connector (abbreviated as BTB) is used to electrically connect two parallel circuit boards, and generally includes a mating plug connector and a socket connector. The plug connector and the socket connector respectively include an insulating body and conductive terminals. The insulating body mainly functions to insulate and position the conductive terminals, and the conductive terminals mainly function to conduct electricity.

[0003] The prior art discloses a board-to-board connector (CN215579139U). At the top of the end of the third protection arm of the connector away from the extension arm, an elastic cantilever is connected. The end of the elastic cantilever away from the third protection arm extends into the accommodation cavity. A clearance groove for avoiding the elastic cantilever is provided at the top of the side wall, and the top surface of the elastic cantilever is arranged lower than the top surface of the second protection arm. From its specification and the accompanying drawings of the specification, it can be known that the elastic cantilever is formed on the second protection arm on the side of the female terminal fitting and extends into the female terminal fitting. The manufacturing process of the elastic cantilever is usually: cutting out a strip part on a metal plate - then bending the strip part - finally forming the elastic cantilever. In the above connector, the processing material of the elastic cantilever comes from the metal plate raw material between the two second protection arms. When the shapes, sizes, and positions of the two second protection arms are determined, the amount of material available for processing the elastic cantilever is also determined. Therefore, the shape and size of the processed elastic cantilever have great limitations. With the progress of communication technology, this kind of structure will not be able to meet the development needs of precision. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a combined structure socket, a connector, and an electronic device using the aforementioned socket or connector, so as to solve the problem in the prior art that the amount of material available for processing the elastic arm is less, resulting in great limitations in the shape and size of the processed elastic arm.

[0013] As a preferred solution of the socket with the above combined structure, the two oppositely arranged elastic arms are elastically displaced in the directions away from each other under an external force. Along the thickness direction of the socket, during the movement process of the above elastic arms, the height of the highest position of the movement of the elastic arms is lower than the height of the lowest point of the accommodation portion.

[0014] As a preferred solution of the socket with the above combined structure, accommodation fitting portions, fixing fitting portions and first introduction fitting portions corresponding to the accommodation portion, the fixing portion and the first introduction portion respectively are arranged on the socket insulator. The accommodation fitting portions, the fixing fitting portions and the first introduction fitting portions are concave structures, and the accommodation portion, the fixing portion and the first introduction portion are respectively embedded in the accommodation fitting portion, the fixing fitting portion and the first introduction fitting portion;

[0015] Along the width direction of the socket, the maximum width between the two corresponding elastic arms during the elastic displacement process is less than the distance between the two accommodation fitting portions corresponding to them, and along the length direction of the socket, the maximum width of each elastic arm is less than the width of the accommodation fitting portion corresponding to it.

[0016] As a preferred embodiment of the above combined structure socket, the socket insulator further includes side arms, the accommodation fitting portion and the side arms are respectively located on opposite sides of the first introduction fitting portion, and the side arms connect two relatively arranged first introduction fitting portions;

[0019] As a preferred embodiment of the above combined structure socket, the signal shielding frame is provided with shielding frame grounding welding feet, the shielding frame grounding welding feet are located on one side of the middle island grounding welding feet, and there is a welding gap between the shielding frame grounding welding feet and the middle island grounding welding feet for welding the two together.

[0020] As a preferred embodiment of the above combined structure socket, the socket conductive terminals are in two groups, each group of socket conductive terminals includes a plurality of socket conductive terminals arranged along the socket length direction, and the two groups of socket conductive terminals are arranged opposite to each other along the socket width direction;

[0021] A partition plate connecting the two is provided between the two middle island reinforcement fixing members, and the partition plate is located between the two groups of socket conductive terminals.

[0022] In a second aspect, the present invention provides a connector, including:

[0026] In summary, the beneficial effects of the present invention are as follows:

In addition, the two elastic arms on the middle island reinforcement fixing piece can produce elastic displacement. During the docking process of the socket and the docking body, when the docking body acts on the contact part of the elastic arm, the elastic arm has a buffering effect on the docking body, which can effectively protect the docking body; the signal shielding frame is arranged around multiple socket conductive terminals. The signal shielding frame is grounded as a whole to shield external signals, preventing external signals of the socket from interfering with the transmission of electrical signals by the conductive terminals; the signal shielding frame has a receiving part corresponding to the elastic arm. Along the length direction of the socket, a fixing part is arranged between the two receiving parts, and a first guiding part outside the two elastic arms. The fixing part can strengthen the strength of the signal shielding frame, and the first guiding part is used to align the docking body inserted into the socket; the middle island reinforcement fixing piece is independently arranged relative to other components of the socket. Along the width direction of the socket, the two relatively arranged elastic arms extend in the direction away from each other. Accordingly, when processing the elastic arms on the plate, the space in the extending direction of the elastic arms is infinite and will not be blocked by other structures. The material for processing the elastic arms is sufficient, and elastic arms of any shape and size can be processed. Adopting this kind of elastic arm structure can adapt to the development of communication technology, especially in the 5G field, and connectors with higher precision can be processed; in addition, the maximum width between the two relatively arranged elastic arms is less than the distance between the two relatively arranged fixing parts, so that the elastic arms processed in the above way are located between the two fixing parts, and the two fixing parts can better protect the elastic arms. And the minimum width between the contact parts of the two relatively arranged elastic arms is less than the distance between the two relatively arranged first guiding parts. During the process of the docking body inserting into the socket, the docking body is aligned first, and then the impact force of the docking body is reduced, which can effectively protect the socket and the docking body.

[0049] Embodiment 1

[0050] Please refer to Figure 1 (a), (b), and (c) of [reference], this embodiment discloses 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.

[0051] Specifically, the connector 10 includes a plug 200 and a socket 100. A fitting recess 110 is formed in the socket 100, and a fitting protrusion 210 is formed on the plug 200. The fitting recess 110 and the fitting protrusion 210 are fitted to each other, and the two are combined into the connector 10. Among them, socket conductive terminals 130 are provided in the socket 100, and plug conductive terminals 220 are provided in the plug 200. The plug conductive terminals 220 are used to connect to the circuit board of one of the electronic components, and the socket conductive terminals 130 are used to connect to the circuit boards of other electronic components. Part of the socket conductive terminals 130 is located in the fitting recess 110, and part of the plug conductive terminals 220 is located on the fitting protrusion 210. When the plug 200 is fitted with the socket 100, the socket conductive terminals 130 are in contact with the plug conductive terminals 220, realizing the electrical connection between the circuit boards of the two electronic components.

[0052] Please refer to Figure 1 and Figure 2 , the embedding direction of the plug 200 relative to the socket 100 is the socket thickness direction Z, the arrangement direction of the socket conductive terminals 130 is the length direction of the socket 100, and the socket width direction Y, the socket length direction X, and the socket thickness direction Z are perpendicular to each other in pairs.

[0053] Embodiment 2

[0054] Please refer to Figure 2 (a) and (b) of, this embodiment discloses a combined structure socket for docking with a docking body, which is the plug of Embodiment 1. The socket 100 includes:

[0055] A socket insulator 120, made of an insulating material, is used to support and separate the various components of the socket 100 to prevent electrical signal interference between the components.

[0056] A plurality of socket conductive terminals 130 arranged along the length direction X of the socket on the socket insulator 120 are used to connect to the conductive terminals of the plug to transmit electrical signals.

[0057] Two middle island reinforcement and fixing members 140 are arranged on the socket insulator 120 on both sides of the socket conductive terminals 130 along the length direction X of the socket. They are used to limit the plug to prevent the plug from being inserted too deeply by mistake, which may damage the socket 100 and the plug, and can reinforce the structure of the connector. Each of the two middle island reinforcement and fixing members 140 has at least two elastic arms 141 arranged opposite to each other along the width direction 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 being fitted with the plug, when the plug acts on the contact portions 1411 of the elastic arms 141, the elastic arms 141 have a buffering effect on the plug, which can effectively protect the plug and the socket 100.

[0058] A signal shielding frame 150 sleeved on a socket insulator 120. The signal shielding frame 150 is disposed around a plurality of socket conductive terminals 130. The overall grounding of the signal shielding frame 150 can shield external signals and prevent the signals outside the socket 100 from interfering with the conductive terminals to transmit electrical signals. It has accommodation parts 151 corresponding to each elastic arm 141, a fixing part 152 disposed between the two elastic arms 141 on this side along the socket length direction X, and a first guiding part 153 disposed outside the two elastic arms 141 on this side along the socket length direction X. The fixing part 152 can strengthen the strength of the signal shielding frame 150, and the first guiding part 153 is used for aligning the plug inserted into the socket 100.

[0059] The middle island reinforcement fixing part 140 is independently disposed relative to other components of the socket 100. The elastic plates 141 are arranged along the socket width direction Y, and the two relatively arranged elastic arms 141 extend in the directions away from each other respectively. Please refer to Figure 2 (b) of. The directions pointed by the two arrows of the middle island reinforcement fixing part 140 are the directions in which the two elastic arms are away from each other. Accordingly, when processing the elastic arms 141 on the plate, the space in the extending direction of the elastic arms 141 is infinite and will not be blocked by other structures. The material for processing the elastic arms 141 is sufficient, and elastic arms 141 of any shape and size can be processed. Adopting this kind of elastic arm 141 structure can adapt to the development of communication technology, especially in the 5G field, and connectors 10 with higher precision can be processed. In addition, the maximum width between the two relatively arranged elastic arms 141 is smaller than the distance between the two relatively arranged fixing parts 152, so that the elastic arms 141 processed in the above way are located between the two fixing parts 152, and the two fixing parts 152 can better protect the elastic arms 141. Moreover, the minimum width between the contact parts 1411 of the two relatively arranged elastic arms 141 is smaller than the distance between the two relatively arranged first guiding parts 153. During the process of the plug being inserted into the socket 100, the plug is first aligned and then the impact force of the plug is reduced, which can effectively protect the socket 100 and the plug.

[0060] To facilitate the understanding of the structure of the socket 100, the components of the socket 100 will be further described as follows:

[0061] Please refer to Figure 3In (a) and (b) thereof, on the socket insulator 120, there are provided a receiving fitting portion 121, a fixing fitting portion 122, and a first introduction fitting portion 123 corresponding to the receiving portion 151, the fixing portion 152, and the first introduction portion 153 respectively. The receiving fitting portion 121, the fixing fitting portion 122, and the first introduction fitting portion 123 are recessed structures. The receiving portion 151, the fixing portion 152, and the first introduction portion 153 are respectively embedded in the receiving fitting portion 121, the fixing fitting portion 122, and the first introduction fitting portion 123, and the signal shielding frame 150 can be better fixed on the socket insulator 120, and the connection is more stable.

[0062] Please refer to Figure 4 In (a) and (b) thereof, the socket insulator 120 further includes a side arm 124. The receiving fitting portion 121 and the side arm 124 are respectively located on both sides of the first introduction fitting portion 123, and the side arm 124 connects two relatively arranged first introduction fitting portions 123, presenting that the side arm 124 is arranged along the width direction Y of the socket. The receiving fitting portion 121, the fixing fitting portion 122, and the first introduction 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 introduction fitting portion 123, and the side arm 124 are connected together to form the framework of the socket insulator 120.

[0063] The socket insulator 120 further includes a bottom wall 125. The bottom wall 125 is located on the side of the side arm 124 facing the socket conductive terminal and at the position where the fitting recess 110 of the socket 100 is located. The bottom wall 125 has a recessed structure. The middle island reinforcing and fixing member 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 from the embedded portion of the bottom wall along the length direction X of the socket. Specifically, the middle island reinforcing and fixing member 140 includes a plate body 142 with a plate-like structure. A part of the structure of the plate body 142 is embedded in the bottom wall 125, and a part of the structure is exposed outside the socket insulator 120. After the plug and the socket are fully fitted, the plug contacts the exposed part of the plate body 142. The plate body 142 can limit the displacement of the plug in the plug and socket insertion direction, prevent the plug from being inserted too deeply by mistake, and thus damage the plug and the socket. In addition, in addition to the bottom wall embedded portion, the plate body 142 also has a side arm embedded portion. In the side arm embedded portion, the plate body 142 is completely embedded in the side arm 124, and the plate body 142 is wrapped by the side arm 124. Here, the connection between the plate body 142 and the side arm 124 is more stable, so that the connection between the middle island reinforcing and fixing member 140 and the socket insulator 120 is more stable.

[0064] Preferably, at the side arm embedding portion where the plate body 142 is embedded in the side arm 124, the plate body 142 has a middle island ground pin 143 that penetrates 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 middle island ground pin 143 is grounded, and the middle island reinforcement fixing member 140 has a signal shielding effect. Specifically, along the socket width direction Y, middle island ground pins 143 are connected to both ends of the plate body 142. The two middle island ground pins 143 extend from the plate body 142 through the inside of the socket insulator 120 to the outside of the socket insulator 120, which not only has the function of grounding but also can enhance the connection stability between the middle island reinforcement fixing member 140 and the socket insulator 120 (restricting the displacement of the middle island reinforcement fixing member 140 in the socket length, width, and thickness directions). Further preferably, along the socket width direction Y, the plate body 142 is also connected with a middle island ground pin 143, and this middle island ground pin 143 also extends to the outside of the socket insulator 120.

[0065] In another embodiment, please refer to Figure 4 and Figure 5 as shown in (c) of, a reinforcing portion 144 is further provided on the middle island ground pin 143. The reinforcing portion 144 is embedded in the side arm 124 of the socket insulator 120 to strengthen the connection between the middle island reinforcement fixing member 140 and the socket insulator 120 by restricting the movement of the middle island reinforcement fixing member 140 relative to the socket insulator 120 in the socket thickness direction Z. Preferably, the reinforcing portion 144 includes a reinforcing plate 1441. The reinforcing plate 1441 is connected to the middle island ground pin 143. The reinforcing plate 1441 is inclined relative to the middle island ground pin 143 with a relatively large slope. The free end of the reinforcing plate 1441 is a hook-shaped structure processed by a bending process, and this hook-shaped structure is embedded in the socket insulator 120.

[0066] Please refer to Figure 4 and Figure 5 as shown in, a protruding middle island 126 is provided in the middle of the socket insulator 120. The fitting recess 110 of the socket is arranged around the middle island 126. Socket portions 145 are provided at the ends where the two relatively arranged middle island reinforcement fixing members 140 approach each other. The two socket portions 145 are sleeved on the middle island 126. An anti-collision portion 146 is provided on the side of the two socket portions 145 facing away from the middle island 126. The anti-collision portion 146 is a circular arc structure, which can smoothly guide the plug 200 into the socket 100.

[0067] Specifically, please refer to Figure 4 as well as Figure 5(a) and (b) thereof, the socket part 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 a 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 its opposite ends respectively. 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 along their gravity direction, so that a fixing space is formed between the first fixing plate 1451 and the second fixing plate 1452, which is convenient for fixing the middle island reinforcing fixing member 140 and the middle island 126.

[0068] Preferably, the socket part 145 further includes a third fixing plate 1453. The third fixing plate 1453 is integrally formed with the second fixing plate 1452. The third fixing plate 1453 is inclined with respect to the surface of the middle island 126. The third fixing plate 1453 is embedded in the middle island 126, and the connection between the middle island 126 and the middle island reinforcing fixing member 140 is more stable.

[0069] In another embodiment, please refer to Figure 5 (c) thereof. There is no notch between the second fixing plate 1452 and the first fixing plate 1451 of the socket part 145, and 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 socket part 145 has higher strength. Specifically, the socket part 145 formed by integrally forming the first fixing plate 1451, the second fixing plate 1452 and the plate body 142 is made by an ultra-precision micro-stretching and extending process.

[0070] Preferably, Figure 5 as shown in (a) and (b) thereof, a reinforcing part 144 as shown in Figure 5 (c) can also be provided on the middle island reinforcing fixing member 140. The shape and advantages of the reinforcing part 144 are as described above.

[0071] Please refer to Figure 2 (a) and (b) thereof. Under the action of an external force, the two relatively arranged elastic arms 141 are elastically displaced in the direction away from each other respectively. Along the socket thickness direction Z, during the movement of the upper elastic arm 141, the height of the highest position of the elastic arm 141 during movement is lower than the height of the lowest point of the accommodating part 151. Accordingly, the elastic arm 141 will never come into contact with the signal shielding frame 150, and no collision and wear will occur between the two, and both can be well protected.

[0072] Further preferably, please refer to Figure 4In (a) and (b) thereof, along the socket width direction Y, the maximum width between the two elastic arms 141 arranged correspondingly is less than the distance between the two accommodating and fitting portions 121 arranged correspondingly to them during the elastic displacement process. Moreover, along the socket length direction X, the maximum width of each elastic arm 141 is less than the width of the accommodating and fitting portion 121 arranged correspondingly to it. Accordingly, the elastic arms 141 move within the space of the accommodating and fitting portions 121 facing the inside of the socket 100, and no collision or abrasion will occur between them, and both can be well protected.

[0073] Preferably, referring to Figure 5 In (a) of, 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 middle island reinforcement fixing member 140. The contact portion 1411 is arranged at the free end of the elastic plate 1412. The elastic plate 1412 is formed by bending the plate body 142 upward along the socket thickness direction Z from bottom to top. The contact portion 1411 of the elastic arm 141 is an arc-shaped structure, and this arc-shaped structure is formed by bending the elastic plates 1412 of the two relatively arranged elastic arms 141 in the direction away from each other respectively. The arc-shaped structure makes the connection between the elastic arm 141 and the plug more stable and the abrasion between them is smaller.

[0074] Further preferably, from the connection part of the elastic arm 141 with the middle island reinforcement fixing member 140 to its extending end part, its width in the socket length direction X gradually decreases, which can ensure both its strong elastic performance and its high structural strength.

[0075] In another embodiment, referring to Figure 5 In (b) and (c) of, the contact portion 1411 of the elastic arm 141 is formed by bending the elastic plates 1412 of the two relatively arranged elastic arms 141 in the direction approaching each other respectively. This kind of structure will make the maximum width of the two relatively arranged elastic arms 141 smaller and the structure of the socket 100 more compact.

[0076] Preferably, referring to Figure 3 In (a) and (b) of, the two first guiding portions 153 arranged oppositely of the signal shielding frame 150 are arranged along the socket length direction X, and a second guiding portion 154 is also arranged between them. The second guiding portion 154 is arranged along the socket width direction Y. Moreover, a third guiding portion 155 is also arranged at the included angle between the second guiding portion 154 and the first guiding portion 153. The first guiding portion 153, the second guiding portion 154 and the third guiding portion 155 are integrally formed and are all arc surfaces, and these arc surfaces are made by an ultra-precision micro-stretching and extending process. Compared with the situation where there is only the first guiding portion 153, the plug blind buckle guiding effect provided by this embodiment is better.

[0077] Embodiment 3

[0078] This embodiment discloses an anti-interference 5G socket. Compared with the socket 100 in Embodiment 2, improvements are made to the signal shielding frame 150 and the socket conductive terminal 130 in this embodiment. For specific improvements, please refer to the following:

[0079] For a plug with plug welding feet, the plug welding feet protrude from its insulating body. Accordingly, when the plug is docked with the socket, the plug welding feet are in close contact with or have only a tiny gap with the surface of the socket. Therefore, during use, the plug welding feet are likely to wear the surface of the socket connector.

[0080] In this embodiment, please refer to Figure 1 (a), (b), (c) of Figure 2 (a), (b) of

[0081] Preferably, please refer to Figure 3 (a) and (b) of

[0082] Regarding the socket conductive terminal 130 on the socket 100:

[0083] Please refer to Figure 7(a), (b), and (c) thereof. There are two groups of socket conductive terminals 130. Each group of socket conductive terminals 130 includes a plurality of socket conductive terminals 130 arranged along the socket length direction X. The two groups of socket conductive terminals 130 are arranged opposite to each other along the socket width direction Y. The socket insulator 120 has a hollow socket conductive terminal mounting portion 128. The two groups of socket conductive terminals 130 are embedded in the socket conductive terminal mounting portion 128. Each socket conductive terminal 130 includes a fixed arm portion 131 fixed to the socket insulator 120. One side of the fixed arm portion 131 has a welding arm portion 132 extending outward from the socket 100. The welding arm portion 132 is welded to the circuit board of the electronic component and is used to transmit electrical signals. The other side opposite to the fixed arm portion 131 has a U-shaped receiving arm portion 133 located inside the socket 100. The plug conductive terminal 220 is embedded in the receiving arm portion 133. The connection between the two conductive terminals is relatively stable. The other side of the receiving arm portion 133 opposite to the side of the fixed arm portion 131 has an elastic arm portion 134 that elastically displaces along the socket width direction Y. Under the elastic force of the elastic arm portion 134, the connection between the two conductive terminals is more stable.

[0084] Preferably, the width of each group of socket conductive terminals 130 arranged in the socket length direction X is less than the distance between the two accommodating portions 151 on this side, that is, the width of each group of socket conductive terminals 130 is less than the length of the fixing portion 152. Along the socket width direction Y, the width between the two fixed arm portions 131 of the two corresponding conductive terminals in the two groups of socket conductive terminals 130 is less than the distance between the two fixing portions 152. This will enable the grounding fixing portion 152 to better shield the interference signals near the socket conductive terminals 130.

[0085] Preferably, the fixed arm portion 131 of each socket conductive terminal 130 includes a first arm 1311, a second arm 1312 and a third arm 1313 respectively 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 portion 132, and the third arm 1313 is connected to the receiving arm portion 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 portion 128 on the socket insulator 120.

[0086] Among them, along the length direction X of the socket, for the fixed arm 131, the width of the second arm 1312 is greater than that of the first arm 1311, and for the socket conductive terminal mounting portion 128, the width of the corresponding portion of the second arm 1312 is greater than that of the corresponding portion of the first arm 1311; for the fixed arm 131, the width of the third arm 1313 is greater than that of the second arm 1312, and for the socket conductive terminal mounting portion 128, the width of the corresponding portion of the third arm 1313 is greater than that of the corresponding portion of the second arm 1312. Accordingly, the connection between the socket conductive terminal 130 and the socket insulator 120 is more stable.

[0087] Further preferably, the second arm 1312 abuts against the corresponding portion of the second arm 1312 on the socket conductive terminal mounting portion 128 to fix 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 portion 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 portion 128. Specifically, there is a certain gap between the second arm 1312 and the third arm 1313 and the insulator, making the elasticity of the socket conductive terminal 130 better, the terminal can be reset, which is convenient for disassembly and assembly. If there is no gap, when the socket conductive terminal 130 bounces, it will scratch the plastic, resulting in the socket conductive terminal 130 not being able to reset. Moreover, due to the existence of the gap, the matching accuracy between the plug conductive terminal 220 and the socket conductive terminal 130 is better, and it can better correct the assembly error between the two. At the same time, this gap also has the function of heat dissipation.

[0088] Embodiment 4

[0089] This embodiment discloses a micro-miniature connector socket with a grounding function. Compared with Embodiment 3, the grounding function of the signal shielding frame 150 and the middle island reinforcement fixing member 140 is improved in this embodiment. Please refer to the following:

[0090] Please refer to Figure 6 , a shielding frame grounding welding leg 156 is provided on the signal shielding frame 150. The shielding frame grounding welding leg 156 is located on one side of the middle island grounding welding leg 143, and there is a welding gap 157 between the shielding frame grounding welding leg 156 and the middle island grounding welding leg 143 for welding the two together.

[0091] Since the middle island reinforcement fixing member 140 is independently arranged relative to the signal shielding frame 150, the structural stability between the two is not very high. Through the setting of the welding gap 157, during the assembly of the connector, the middle island reinforcement fixing member 140 and the signal shielding frame 150 are designed in a separated manner, having the advantages of any one of the socket 100 in the foregoing Embodiment 1 - Embodiment 3; after the connector assembly is completed, the middle island reinforcement fixing member 140 and the signal shielding frame 150 are welded together through the welding gap 157, and the two can be regarded as an integrally formed structure, with relatively high connection strength and better stability of the connector.

[0092] Embodiment 5

[0093] This embodiment discloses a micro - miniature connector socket with a signal shielding function. Compared with Embodiment 4, this embodiment has improvements in shielding interference signals. Please refer to the following:

[0094] Please refer to Figure 2 of (b), Figure 4 of (b), a partition board 160 connecting the two middle island reinforcement fixing members 140 is arranged between the two middle island reinforcement fixing members 140. The partition board 160 is located between two groups of socket conductive terminals 130 and is arranged inside the middle island 126. In the length direction X of the socket, the width of the partition board 160 is greater than the width of any group of socket conductive terminals 130, and in the thickness direction Z of the socket, the height of the partition board 160 is greater than the height of any socket conductive terminal 130. Accordingly, the partition board 160 can prevent interference between the two groups of socket conductive terminals 130.

[0095] Preferably, as Figure 4 (b) shows, along the width direction Y of the socket, a reinforcing hole 161 penetrating through the partition board 160 is formed on the partition board 160. There are multiple reinforcing holes 161, and the multiple reinforcing holes 161 are uniformly arranged along the length direction X of the socket on the partition board 160. Correspondingly, as Figure 7 (a) shows, multiple reinforcing columns 1261 are arranged on the middle island 126, and the multiple reinforcing columns 1261 penetrate through the multiple reinforcing holes 161. Accordingly, the connection between the partition board 160 and the middle island 126 is more stable.

[0096] Preferably, as Figure 2 (b) shows, the partition board 160 is provided with protrusions and depressions, and the protrusions and depressions are arranged alternately along the length direction of the socket. The protrusions penetrate through the insulator from the inside of the socket insulator to the outside of the socket insulator, which can ensure the stability of the partition board in the thickness direction of the socket.

[0097] The protruding part is located directly below the reinforcing hole 161 and is the same in number as the reinforcing hole 161. Due to the existence of the reinforcing hole 161, the overall width of the partition plate 160 is reduced. Therefore, setting the protruding part directly below the reinforcing hole 161 ensures that the overall width of the partition plate 160 does not decrease. If the recessed part is set directly below the reinforcing hole, the width of the partition plate 160 will be too low, and the strength of the partition plate 160 will be affected.

[0098] In this embodiment, the middle island reinforcing and fixing member 140 does not have a socket part 145.

[0099] In another embodiment, please refer to Figure 8 , to prevent the plug from damaging the socket when the plug is engaged with the socket, a collision-preventing arm 147 is machined on the plate body 142 of the middle island reinforcing and fixing member 140. The collision-preventing arm 147 has an arc-shaped structure and can smoothly guide the plug into the socket.

[0100] The processing flow of the collision-preventing arm 147 is as follows:

[0101] 1. First, cut a section along the length direction X of the socket on the plate, then cut a section along the width direction Y of the socket, and finally cut a section along the length direction X of the socket again. Thus, a plate for machining the collision-preventing arm 147 is formed on the plate body 142.

[0102] 2. Bend the plate upward along the thickness direction Z of the socket at the connection of the plate body 142, and then fold its free end into an arc-shaped structure. Thus, the collision-preventing arm 147 is machined.

[0103] Further preferably, a reinforcing part 144 can also be provided on the middle island reinforcing and fixing member 140. The shape and advantages of the reinforcing part 144 are the same as those in Embodiment 2.
