Description

Technical Field

[0001] This utility model relates to the field of signal connection technology, and in particular to a board-to-board connector male socket. Background Technology

[0002] In electronic products, electrical connectors are typically used to enable quick connection and disconnection between different devices. Currently, the pins and body of connector sockets are injection molded. During manufacturing or repeated use, when one or more pins become damaged, the entire socket needs to be replaced, increasing costs. Furthermore, because the body is injection molded, connector sockets with many pins are usually quite long and wide. However, due to space constraints in devices using these sockets, there are often strict requirements on the connector's volume. Consequently, the plastic material portion is often thin and long, making it prone to shrinkage and deformation during molding. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a male connector for board-to-board connectors. This male connector can reduce shrinkage and deformation during molding, and the pins can be replaced independently, thereby reducing costs.

[0004] To solve the above-mentioned technical problems, this utility model provides a board-to-board connector male socket. The board-to-board connector male socket includes a main body with a fixed end and a plug-in end and a first conductive body. The plug-in end of the main body has a cavity. The first conductive body includes a first fixing part and plug-in parts and a first welding part located at both ends of the first fixing part. The cavity has a first through hole that is consistent with the plug-in direction. The first conductive body is disposed in the first through hole. The first through hole includes a first fixing hole and a second fixing hole that communicates with the first fixing hole along its length direction. The cross-sectional area of ​​the first fixing hole is larger than that of the second fixing hole. When the first conductive body is fixed to the main body, the surface of the first fixing part is partially press-fitted with the wall of the first fixing hole. The surface of the plug-in part is press-fitted through the second fixing hole and suspended in the cavity. Because the cross-sectional area of ​​the first fixing hole is larger than that of the first fixing part, the surface of the first fixing part partially has an interference fit with the first fixing hole, while the surface of the insertion part has an interference fit with the surface of the second fixing hole. This creates a gap between the first fixing part and the first fixing hole, thereby reducing shrinkage deformation during the molding of the main body. Simultaneously, the interference fit between the insertion part and the wall of the second fixing hole enhances the stability of the fixation with the main body. Furthermore, the interference fit between the first fixing part and the first fixing hole increases the tangential force strength along the length of the first conductor, effectively stabilizing the fixation stability and mitigating shrinkage during the injection molding of the main body.

[0005] In one specific embodiment, the first fixing part includes two outwardly extending shoulders, each shoulder forming an extension portion away from the insertion part. A clearance groove is provided between each extension portion and the shoulder. The two extension portions form a notch at the end away from the first fixing part. One side of the first fixing part has a groove, and the opposite side has a corresponding fixing protrusion that abuts against the wall of the first fixing hole during fixing. By having the fixing protrusion cooperate with the wall of the first fixing hole, the insertion part and the first fixing part are not on the same straight line, enhancing the stability of the fixing of the first conductor to the main body, while also providing space to reduce the size of the main body during molding. The notch facilitates easier position adjustment when welding the first welding part, and provides some movement space for the two extension portions when the first conductor needs to be disassembled, reducing the force between the sides and the first fixing hole, thus making disassembly easier.

[0006] In one specific embodiment, the main body further includes a second conductor and a second through hole for fixing the second conductor. The second conductor includes a second fixing part, conductive spring pieces disposed at both ends of the second fixing part, and a second welding part. The second fixing part has at least two second fixing protrusions. The second through hole includes a mounting hole and a clearance hole that communicates vertically with the mounting hole. The mounting hole is wider than the clearance hole. The clearance hole communicates with a mounting groove on a fixing strip in the cavity. During installation, the conductive spring piece is located in the mounting groove, and the two second fixing protrusions abut against the wall of the mounting hole for fixation. Through the abutment and engagement of the second fixing protrusions with the wall of the mounting hole, the second fixing part and the mounting hole can be reliably fixed. At the same time, when fixing the conductive spring piece, its end can be tucked into the mounting groove, avoiding warping during insertion and causing deformation and damage to the conductive spring piece. In addition, the mounting hole and clearance hole can further reduce deformation caused by shrinkage during molding.

[0007] In one specific embodiment, the conductive spring includes a contact portion and a connecting portion, as well as a bent portion disposed in front of the contact portion. The contact portion and the second fixing portion are not disposed on the same plane, which can enable the contact portion to maintain a certain elastic deformation space and better conductivity when under pressure.

[0008] In one specific embodiment, a telescopic gap is provided between the bent portion and the end of the mounting groove. This telescopic gap allows the conductive spring to have sufficient deformation space when forming an electrical connection with the outside, preventing deformation of the conductive spring during the insertion process, which could lead to damage or reduced electrical performance.

[0009] In one specific embodiment, a gap is provided between the contact portion and the mounting groove, which can maintain a certain clamping force for the contact portion to form an electrical connection and improve the stability of the electrical connection.

[0010] In one specific embodiment, the second fixing part is provided with protrusions on both sides, which abut against the mounting hole when fixed. The number of these protrusions can be one, two or more, and they can contact the wall of the mounting hole to improve the stability of the installation.

[0011] In one specific embodiment, the conductive spring sheet is provided with first openings on both sides of the connection between the conductive spring sheet and the second fixing part. The first openings can ensure that the conductive spring sheet has a certain degree of lateral mobility and overall elasticity.

[0012] In one specific embodiment, a second opening is provided on both sides of the connection between the second welding part and the second fixing part, and the second opening can ensure that the second welding part has a certain degree of lateral mobility.

[0013] In one specific embodiment, the first through hole includes upper and lower sets, and a first anti-shrinkage groove is provided between the two sets of first through holes at the bottom of the cavity. The first anti-shrinkage groove can prevent the large main body from shrinking and deforming when the main body is injection molded.

[0014] In one specific embodiment, the two sets of first fixing holes at the fixing end are provided with a second anti-shrinkage groove, which can further prevent the large main body from shrinking and deforming when the main body is injection molded.

[0015] In one specific embodiment, the first conductor includes two sets of conductive needles, each set having multiple conductive needles, and each conductive needle is independently disposed in the first fixing hole.

[0016] In one specific embodiment, the insertion portion of the conductive pin is arranged perpendicularly to the first welding portion.

[0017] In one specific embodiment, the cavity has a guide opening on one side.

[0018] In one specific embodiment, the clearance groove is provided with a first inclined surface and a second inclined surface, the angle between the first inclined surface and the clamping arm is smaller than the angle between the second inclined surface and the clamping arm.

[0019] This utility model discloses a board-to-board connector male socket, comprising a main body with a fixed end and a plug-in end, and a first conductive body. The plug-in end of the main body has a cavity. The first conductive body includes a first fixing part and plug-in parts and a first welding part located at both ends of the first fixing part. The cavity has a first through hole aligned with the plug-in direction. The first conductive body is disposed within the first through hole. The first through hole includes a first fixing hole and a second fixing hole communicating along the length of the first fixing hole. The cross-sectional area of ​​the first fixing hole is larger than that of the second fixing hole. When the first conductive body is fixed to the main body, the surface of the first fixing part partially interferes with the wall of the first fixing hole, and the surface of the plug-in part is interference-fitted through the second fixing hole and suspended in the cavity. Because the cross-sectional area of ​​the first fixing hole is larger than that of the first fixing part, and the surface of the first fixing part partially interferes with the first fixing hole, while the surface of the plug-in part is interference-fitted with the surface of the second fixing hole, a gap exists between the first fixing part and the first fixing hole. This reduces shrinkage deformation during the molding of the main body. At the same time, the interference fit between the plug-in part and the wall of the second fixing hole enhances the stability of the connection with the main body. In addition, the interference fit between the first fixing part and the first fixing hole can increase the tangential force strength along the length of the first conductor, which greatly stabilizes the fixing stability and reduces the shrinkage of the main body during injection molding.

[0035] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0036] like Figure 1-7 As shown, this utility model provides an embodiment of a board-to-board connector male socket.

[0037] The board-to-board connector male socket includes a main body 1 with a fixed end and a plug end. The plug end of the main body has a cavity 11. The cavity 11 has a first conductor 2 that passes through the fixed end and the plug end. The first conductor 2 includes a first fixing part 20 and plug parts 22 and a first welding part 21 located at both ends of the first fixing part 20. The bottom of the cavity 11 has a first through hole 15 that is consistent with the plugging direction. The first conductor 2 is located in the first through hole 15. The first through hole 15 includes a first fixing hole 151 and a second fixing hole 152 that communicates with the first fixing hole 151. The cross-sectional area of ​​the first fixing hole 151 is larger than that of the second fixing hole 152. When the first conductor 2 is fixed to the main body 1, the first fixing part 20 is fixed in the first fixing hole 151. The plug part 22 passes through the second fixing hole 152 and is suspended in the cavity 11. The surface of the first fixing part 20 is partially press-fitted with the wall of the first fixing hole 151. The surface of the second fixing hole 152 is press-fitted with the surface of the plug part 22.

[0038] Specifically, the main body 1 is injection molded from a thermoforming material such as plastic, and the first conductor 2 is made of a material with good conductivity, typically copper or steel. The first conductor 2 is arranged in two rows, with 13 conductors in each row, as an example.

[0039] The connector male socket includes a main body 1 and a first conductor 2. The insertion end of the main body 1 has a cavity 11, and one side of the cavity 11 has a guide opening 13. The first conductor 2 includes a first fixing part 20 and a insertion part 22 and a first welding part 21 located at both ends of the first fixing part. The first insertion part 22 and the first welding part 21 can be arranged perpendicularly, or in other forms as needed. The cavity 11 has a first through hole 15 aligned with the insertion direction. The first conductor 1 is disposed in the first through hole 15. The first through hole 15 includes a first fixing hole 151 and a second fixing hole 152 communicating along the length direction of the first fixing hole 151. The cross-sectional area of ​​the first fixing hole 151 is larger than that of the second fixing hole 152. When the first conductor 2 is fixed to the main body 1, the surface of the first fixing part 20 is partially press-fitted with the wall of the first fixing hole 151, and the surface of the insertion part 22 is press-fitted through the second fixing hole 152 and suspended in the cavity 11. The first conductor 2 includes two sets of conductive pins, each independently disposed within the first fixing hole 15. Since the cross-sectional area of ​​the first fixing hole is larger than that of the first fixing part, a partial interference fit is made between the surface of the first fixing part and the first fixing hole, while the insertion part and the surface of the second fixing hole are both interference-fitted. This creates a gap between the first fixing part and the first fixing hole, thereby reducing shrinkage deformation during the molding of the main body. Simultaneously, the interference fit between the insertion part and the wall of the second fixing hole enhances the stability of the fixation with the main body. Furthermore, the interference fit between the first fixing part and the first fixing hole increases the tangential force strength along the length of the first conductor, effectively stabilizing the fixation stability and mitigating shrinkage during the injection molding of the main body.

[0040] In one specific embodiment, the first fixing part 20 includes two outwardly extending shoulders 201. Each shoulder 201 forms an extension 23 in a direction away from the insertion part 22. A clearance groove 24 is provided between each extension 23 and the shoulder 201. The two extensions 23 form a notch 27 at the end away from the first fixing part 20. One side of the first fixing part 20 is provided with a groove 25, and the other side opposite to the groove 25 is provided with a first fixing protrusion 26 that abuts against the wall of the first fixing hole 151 when fixed. By having the first fixing protrusion 26 abut against the wall of the first fixing hole 151, the contact with the first fixing hole 151 can be increased, and the other side of the first fixing part 20 can also abut against the wall of the first fixing hole 151, thereby improving the stability of the fixing. Meanwhile, the cross-section of the first fixing hole 151 is larger than that of the first fixing part 20. When the first fixing protrusion 26 mates with the first fixing hole 151, the first fixing part 20 is not coplanar, meaning the insertion part and the first fixing part are not on the same straight line. This enhances the stability of the first conductor 2 and the main body 1 and provides space to reduce the deformation of the main body 1 during injection molding. The notch 27 facilitates easier position adjustment when welding the first welding part 21 and provides a certain amount of movement space for the two extensions 23 when the first conductor 2 needs to be disassembled, reducing the force between the side and the first fixing hole, making disassembly easier. The clearance groove 24 is designed to reduce the friction between the first fixing hole 151 and the first fixing hole during disassembly, facilitating disassembly.

[0041] As needed, the clearance groove 24 is provided with a first inclined surface 241 and a second inclined surface 242. The angle between the first inclined surface 241 and the clamping arm 201 is smaller than the angle between the second inclined surface 242 and the clamping arm. That is, the first inclined surface 241 is longer, so it is easier to deform under external force during disassembly, thus facilitating disassembly.

[0042] In one specific embodiment, the main body 1 further includes a second conductor 3 and a second through hole 16 for fixing the second conductor. The second conductor 3 is disposed on both sides of each row of first conductors 2. The second conductor 3 includes a second fixing part 30 and conductive spring pieces 32 and second welding parts 31 disposed at both ends of the second fixing part 30. The conductive spring pieces 32 and the second welding parts 31 are described as two each. As needed, the conductive spring pieces 32 and the second welding parts 31 can also be one or more. When there are two or more, each conductive spring piece 32 is arranged in parallel with each other, and each second welding part 31 is arranged in parallel with each other. The second fixing part 30 has at least two second fixing protrusions 302 on the same surface. The second through hole 16 includes a mounting hole 161 and a clearance hole 162 that communicates vertically with the mounting hole 161. The mounting hole 161 is wider than the clearance hole 162. The clearance hole 162 communicates with the mounting groove 121 on the fixing strip 12 of the cavity 11. During installation, the conductive spring piece 32 is located in the mounting groove 121, and the two second fixing protrusions 302 abut against the wall of the mounting hole 161. The mounting groove 121 communicates with the cavity 11. During installation, the conductive spring piece 32 passes through the clearance hole 162 into the cavity 11 and is located in the mounting groove 12. The second fixing part 30 is located in the mounting hole 161 and is reliably fixed to the mounting hole 161 by the second fixing protrusions 302 abutting against the wall of the mounting hole 161. Meanwhile, when fixing the conductive spring 32, its end can be tucked into the mounting groove 121, preventing it from warping during insertion and causing deformation or damage to the conductive spring 32. Furthermore, the mounting hole 162 and the clearance hole 162 further reduce deformation caused by shrinkage during molding.

[0043] In one specific embodiment, the conductive spring 32 includes a contact portion 321 and a connecting portion 323, as well as a bent portion 322 disposed at the front of the contact portion 321. The contact portion 321 is not on the same plane as the second fixing portion 30. The bent portion 322 is in the opposite direction to the connecting portion 323. A gap is provided between the contact portion 321 and the mounting groove 121. The gap between the contact portion 321 and the mounting groove 121 can maintain a certain clamping force for the contact portion to form an electrical connection, improve the stability of the electrical connection, maintain a certain elastic deformation space when the contact portion is compressed, and improve conductivity. As needed, a first opening 307 is provided on both sides of the connection between the conductive spring 32 and the second fixing portion 30. The first opening 307 can ensure that the conductive spring 32 has a certain degree of lateral mobility and the overall elasticity of the conductive spring. A second opening 303 is provided on both sides of the connection between the second welding portion 31 and the second fixing portion 30. The second opening 303 can ensure that the second welding portion 31 has a certain degree of lateral mobility.

[0044] In one specific embodiment, a telescopic gap (not shown in the figures) is provided between the bent portion 322 and the end of the mounting groove 121, and the bent portion 322 and the connecting portion 323 are in opposite directions. This telescopic gap provides good deformation space for the conductive spring when forming an electrical connection with the outside, avoiding deformation of the conductive spring during the insertion process, which could lead to damage or reduced electrical performance.

[0045] In one specific embodiment, a first anti-shrinkage groove 18 is provided between the two sets of first through holes 15 at the bottom of the cavity 11. The first anti-shrinkage groove 18 can prevent the larger body from shrinking and deforming when the main body is injection molded. The two sets of first fixing holes 15 at the fixing end are provided with a second anti-shrinkage groove 17. The second anti-shrinkage groove 17 can further prevent the larger body from shrinking and deforming when the main body is injection molded.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
