Description

Technical Field

[0001] This application relates to the field of connector technology, and more particularly to a positioning post for a connector and a connector having the same. Background Technology

[0002] The connector is mounted on the circuit board and is used to connect to test instruments used to test the chip.

[0003] When mounting the connector on the circuit board, it is positioned by inserting positioning pins into the positioning holes on the circuit board, ensuring that all solder pads on the connector are within the soldering holes on the circuit board. After the connector is correctly positioned, the solder pads of the connector are soldered into the soldering holes on the circuit board.

[0004] Currently, positioning holes on circuit boards are typically circular, while positioning posts on connectors are cylindrical. Positioning is achieved by inserting the cylindrical positioning posts into the circular positioning holes. However, this mating method requires a clearance between the two components; otherwise, assembly is impossible. This clearance leads to positioning deviations during the positioning process, causing the connector's solder pads to not be precisely positioned within the solder holes on the circuit board, thus failing to meet precise positioning requirements. Utility Model Content

[0005] The purpose of this application is to provide a positioning post for a connector and a connector having the same, wherein the positioning post of the connector will not interfere with the positioning hole when mated, thus solving the problem that the existing positioning post cannot be accurately positioned.

[0006] Therefore, in a first aspect, embodiments of this application provide a positioning post for a connector, the positioning post having a semi-cylindrical structure, the opposite sides of the positioning post being a top surface and a bottom surface, an outer wall surface being provided between the top surface and the bottom surface, the bottom surface being used to connect with the housing of the connector, and the outer wall surface being used to mate with the positioning hole of the circuit board.

[0007] In one possible implementation, the outer wall surface includes a connected curved surface and a rectangular surface, and the end of the rectangular surface connected to the bottom surface is provided with an arc surface.

[0008] In one possible implementation, the outer wall surface includes a connected curved surface and a rectangular surface, with ribs provided on the rectangular surface.

[0009] In one possible implementation, the positioning post includes a connected semi-circular frustum and a cylindrical portion, with the side of the cylindrical portion away from the semi-circular frustum connected to the housing.

[0010] In one possible implementation, the outer wall surface includes a connected curved surface and a rectangular surface, and a connecting plane is provided at the connection between the curved surface and the rectangular surface.

[0011] Secondly, embodiments of this application provide a connector, which includes a housing and positioning posts of the connector described in the first aspect. The connector is used to mate with a circuit board, on which two positioning holes are spaced apart. Two positioning posts are provided, and the two positioning posts are respectively embedded in the two positioning holes.

[0012] In one possible implementation, the inner wall surface of the positioning hole is a positioning wall surface, the position of the two positioning walls that are far apart from each other is the positioning distal end of the positioning wall surface, and at least part of the outer wall surface mates with the positioning distal end of the corresponding positioning hole.

[0013] In one possible implementation, the two positioning posts are arranged in an axisymmetric structure.

[0014] In one possible implementation, the housing contains an insulating block and a connecting terminal, the connecting terminal being integrally formed with the insulating block.

[0015] In one possible implementation, the connection terminal includes:

[0016] The first part is U-shaped and includes a vertically positioned first end and a second end, connected by a horizontally positioned connecting portion. The height of the first end is greater than the height of the second end.

[0017] The second part is a long strip structure and is parallel to the connecting part. The second part is connected to the second end.

[0018] According to the embodiments of this application, a connector positioning post and a connector having the same are provided. When the connector is inserted into a circuit board, the outer wall of the positioning post tightly fits the inner wall of the positioning hole, ensuring accurate positioning and stable fixation of the connector. While traditional circular positioning post designs can achieve positioning, the required gap for assembly can lead to insufficient positioning accuracy or even interference in some cases. The semi-circular positioning post design used in this application allows the positioning post to tightly fit with the positioning hole of the circuit board, achieving precise positioning. Furthermore, its semi-circular shape avoids interference problems caused by excessive gaps, and also meets the requirements of high-precision board manufacturing. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] First Embodiment

[0046] like Figures 1-4 As shown, this application embodiment provides a positioning post for a connector. The positioning post 1 is arranged in a semi-cylindrical structure. The opposite sides of the positioning post 1 are a top surface 11 and a bottom surface 12, respectively. An outer wall surface 13 is connected between the top surface 11 and the bottom surface 12. The bottom surface 12 is used to connect with the housing 2 of the connector, and the outer wall surface 13 is used to cooperate with the positioning hole 31 of the circuit board 3.

[0047] Specifically, the cross-sectional shape of the positioning post 1 can be semi-circular or semi-elliptical to accommodate positioning holes 31 of different shapes.

[0048] The positioning post 1 has a top surface 11 and a bottom surface 12 on opposite sides. The top surface 11 and the bottom surface 12 are parallel and perpendicular to the axis of the positioning post 1. The connecting part between the top surface 11 and the bottom surface 12 is the outer wall surface 13, which is the side of a semi-cylinder and is used to mate with the positioning hole 31 of the circuit board 3.

[0049] The bottom surface 12 is used to connect with the connector housing 2. Specifically, the bottom surface 12 can be fixed to the housing 2 by welding, screw fixing, or bonding. This connection method ensures the stability and reliability of the positioning post 1. Of course, the positioning post 1 can also be integrally formed with the connector housing 2, in which case the bottom surface 12 is integrally formed with the housing 2.

[0050] The outer wall surface 13 is used to mate with the positioning hole 31 of the circuit board 3. The positioning hole 31 is a pre-set hole on the circuit board 3 used to fix and position the connector. When the connector is inserted into the circuit board 3, the outer wall surface 13 of the positioning post 1 fits tightly with the inner wall of the positioning hole 31 to ensure accurate positioning and stable fixation of the connector.

[0051] In practical applications, the material of the positioning post 1 can be metal or plastic, depending on the connector's operating environment and cost requirements. If the connector needs to withstand significant mechanical stress, a metal positioning post 1 can be selected; if cost is the primary consideration, a plastic positioning post 1 can be chosen.

[0052] In summary, by using the semi-cylindrical positioning post 1 in conjunction with the positioning hole 31 on the circuit board 3, accurate positioning and stable fixation of the connector are achieved, improving the connector's reliability and service life. While traditional circular positioning post 1 designs can achieve positioning, the required clearance for assembly can lead to insufficient positioning accuracy or even interference in some cases. The semi-circular positioning post 1 design used in this application allows for a tight fit between the positioning post 1 and the positioning hole 31 on the circuit board 3, achieving precise positioning. Furthermore, its semi-circular shape avoids interference problems caused by excessive clearance, and also meets the requirements of high-precision board manufacturing.

[0053] Reference Figures 1 to 5In some embodiments, the outer wall surface 13 includes a curved surface 131 and a rectangular surface 132 connected together, with an arc surface 133 at the end where the rectangular surface 132 connects to the bottom surface 12. The outer wall surface 13 of the positioning post 1 is designed as a semi-cylindrical structure, containing a curved surface 131 and a rectangular surface 132. The curved surface 131 allows the positioning post 1 to fit tightly with the positioning hole 31 of the circuit board 3, while the rectangular surface 132 provides additional stability and support. This design enables the positioning post 1 to achieve precise positioning without interfering with other components of the circuit board 3. The end where the rectangular surface 132 connects to the bottom surface 12 is specially designed with an arc surface 133. This arc surface 133 not only increases the contact area between the positioning post 1 and the circuit board 3, but also provides a smooth transition, further ensuring the smoothness and stability of the positioning post 1 during insertion and removal.

[0054] The outer wall surface 13 includes a curved surface 131 and a rectangular surface 132 connected to each other. Ribs 15 are provided on the rectangular surface 132, and the two ends of the ribs 15 are respectively connected to the rectangular surface 132 and the shell 2. By providing ribs 15 on the rectangular surface 132, the structural strength of the positioning post 1 is enhanced, ensuring accurate positioning. It also has high strength and mass production capability.

[0055] With increasingly high labor costs, automated manufacturing is now used for product board mounting. This places increasingly stringent quality requirements on our products, demanding precise dimensions, controllable structure, and accurate positioning. The positioning post 1 of the connector provided in this application, while meeting customer needs, is designed as a semi-cylindrical structure with ribs 15 attached, satisfying both the requirements for precise positioning and manufacturability.

[0056] Reference Figures 1 to 5 In some embodiments, the positioning post 1 includes a connected frustum 16 and a columnar portion, with the side of the columnar portion away from the frustum 16 connected to the housing 2. The columnar portion is used to connect to the housing 2, and the frustum 16 is located on the side of the columnar portion away from the housing 2. The structure of the frustum 16 facilitates the insertion and connection between the positioning post 1 and the positioning hole 31, ensuring smooth and stable insertion and removal processes.

[0057] Of course, a connecting plane 14 can also be provided at the connection between the curved surface 131 and the rectangular surface 132. By providing the connecting plane 14, when the positioning post 1 is inserted into the positioning hole 31, there is a connection gap between the connection between the curved surface 131 and the rectangular surface 132 and the positioning hole 31. That is, the side of the connecting plane 14 connected to the curved surface 131 is in contact with the positioning hole 31, and the side of the connecting plane 14 connected to the rectangular surface 132 is spaced apart from the positioning hole 31. This facilitates the insertion and removal of the positioning post 1 from the positioning hole 31, avoids interference between the connection between the curved surface 131 and the rectangular surface 132 and the positioning hole 31, and also ensures the structural strength of the positioning post 1.

[0058] In summary, the positioning post 1 provided in this embodiment adopts a semi-cylindrical structure, ensuring precise positioning of the connector during installation and improving installation accuracy and reliability. It effectively avoids interference when the connector mates with the circuit board 3, as its shape perfectly matches the shape of the positioning hole 31, requiring no additional gap and thus reducing obstacles during installation. The ribs 15 and other structures provide additional strength and stability to the positioning post 1, ensuring it is not easily deformed or damaged under external forces, enhancing the overall stability of the connector. Furthermore, the smooth transition between the positioning post 1 and the connector housing 2 helps reduce stress concentration and improves the durability of the positioning post 1.

[0059] Reference Figures 1 to 5 This application also provides a connector, which includes a housing 2 and a positioning post 1 as described in the foregoing embodiments, the positioning post 1 being disposed on the housing 2. The connector with the positioning post 1 described in the foregoing embodiments ensures precise positioning of the connector during installation, improving installation accuracy and reliability. It also meets customer requirements for high-precision circuit board fabrication, improving production and maintenance efficiency through rapid assembly and high stability. Because the stability and reliability of the connector are improved, the end-user experience is also enhanced, reducing equipment failures and maintenance needs caused by connector problems.

[0060] It should be noted that the connector described in this application does not limit the type of connector. This design of the positioning post 1 can be widely used in various RJ45 connectors, especially in applications requiring frequent mating and high stability, such as data centers, network equipment and high-speed communication equipment.

[0061] Specifically, the connector is used to mate with the circuit board 3, which has two positioning holes 31 spaced apart. Two positioning posts 1 are provided, each embedded within one of the two positioning holes 31. This connection method achieves precise mating between the connector and the circuit board 3, while ensuring the stability and reliability of the connector.

[0062] The connector mates with circuit board 3, which has two spaced-apart positioning holes 31. These holes 31 are designed to precisely match the positioning posts 1 on the connector, thus achieving stable fixation and accurate positioning of the connector. Each positioning hole 31 is designed to receive a corresponding positioning post 1, ensuring accurate alignment of the connector when inserted into circuit board 3.

[0063] Two positioning posts 1 are provided, each corresponding to one of the two positioning holes 31 on the circuit board 3. Each positioning post 1 is designed to fit into the corresponding positioning hole 31. This fitting design not only provides mechanical stability but also helps prevent the connector from rotating or shifting during use. The shape and size of the positioning post 1 are precisely matched with the positioning hole 31, ensuring a tight fit between the connector and the circuit board 3.

[0064] During the mating process between the connector and the circuit board 3, the two positioning pins 1 are respectively embedded in the two positioning holes 31. This mating method provides stability for the connector in the X and Y axis directions, while also limiting the movement of the connector in the Z axis direction, thereby ensuring precise mating between the connector and the circuit board 3. The mating of the positioning pins 1 and the positioning holes 31 also helps to disperse the force generated when the connector is inserted or removed, reducing damage to the circuit board 3 or the connector.

[0065] By adopting this design, the connector can not only be assembled quickly, but also ensure stability and reliability during long-term use, thereby meeting customers' requirements for high-precision circuit board fabrication.

[0066] Reference Figures 1 to 6 In some embodiments, the inner wall surface of the positioning hole 31 is a positioning wall surface 311, and the positions where the two positioning walls 311 are far apart from each other are the positioning distal ends of the positioning wall surfaces 311. At least a portion of the outer wall surface 13 mates with the corresponding positioning distal end of the positioning hole 31. By ensuring that at least a portion of the outer wall surface 13 mates with the positioning distal end of the positioning hole 31, the maximum distance between the two positioning posts 1 is guaranteed, further ensuring the positioning effect after the two positioning posts 1 mate with the positioning hole 31. Optionally, the two positioning posts 1 are arranged in an axisymmetric structure.

[0067] Combination Figure 7In some embodiments, the housing 2 contains an insulating block 4 and a connecting terminal 5, with the connecting terminal 5 integrally formed with the insulating block 4. The insulating block 4 in the housing 2 ensures the safety of the electrical connection and prevents short circuits between different signal or power lines. The connecting terminal 5 in the housing 2 is used to achieve the electrical connection. The integral forming of the connecting terminal 5 with the insulating block 4 improves the overall structural stability of the connector because there is no separate connection interface between the connecting terminal 5 and the insulating block 4, reducing the risk of failure due to poor connection. Furthermore, the integral forming manufacturing process simplifies the production process, reduces assembly steps, thereby improving production efficiency and reducing costs. It also ensures a tight fit between the insulating block 4 and the connecting terminal 5, reducing displacement caused by vibration or thermal expansion and improving the reliability of the connector.

[0068] Specifically, the connecting terminal 5 is embedded in the insulating block 4, and the two ends of the connecting terminal 5 protrude from the insulating block 4 to achieve electrical connection.

[0069] Reference Figures 7 to 11 The connecting terminal 5 includes a first part 51 and a second part 52. The first part 51 has a U-shaped structure and includes a vertically arranged first end 511 and a second end 512. A horizontally arranged connecting portion 513 connects the first end 511 and the second end 512. The height of the first end 511 is higher than the height of the second end 512. The second part 52 has an elongated structure and is parallel to the connecting portion 513. The second part 52 is connected to the second end 512. The side of the second part 52 away from the second end 512 and the first end 511 of the first part 51 are the two ends of the connecting terminal 5 for electrical connection. By setting the connecting terminal 5 in the above form, the customer's need for pin positions is met, and the connecting terminal 5 can be stably embedded in the insulating block 4, ensuring the sealing effect of the product and guaranteeing the pin retention force.

[0070] In some embodiments, the connector may also include connection terminals 5 with other structures, such as connection terminals 5 with an overall L-shaped structure. For ease of distinction, the connection terminal 5 of the above form can be a first connection terminal 53, and the connection terminal 5 with the L-shaped structure can be a second connection terminal 54. Specifically, the first connection terminal 53 and the second connection terminal 54 are spaced apart on the insulating block 4, and both the first connection terminal 53 and the second connection terminal 54 are embedded in the insulating block 4. Both ends of the first connection terminal 53 and both ends of the second connection terminal 54 protrude from the insulating block 4 to achieve electrical connection.

[0071] Of course, the terminal shape of the connector in this embodiment can be adapted to actual needs. The number of terminals in the connector can also be adapted to actual needs. That is, multiple first connecting terminals 53 can be provided, and multiple second connecting terminals 54 can also be provided.

[0072] For example, taking an RJ45 connector as an example, multiple first connecting terminals 53 and multiple second connecting terminals 54 are provided. The first connecting terminals 53 and the second connecting terminals 54 are arranged alternately, and each first connecting terminal 53 and each second connecting terminal 54 is embedded in an insulating block 4 and integrally formed with the insulating block 4. The insulating block 4 includes a first insulating surface 41 and a second insulating surface 42 connected at an angle. Optionally, the angle between the first insulating surface 41 and the second insulating surface 42 is a right angle. Of course, under different requirements, the angle between the first insulating surface 41 and the second insulating surface 42 can also be an acute angle or an obtuse angle.

[0073] Specifically, the first end of each first connecting terminal 53 and the first end of each second connecting terminal 54 protrudes from the first insulating surface 41, and the second end of each first connecting terminal 53 and the second end of each second connecting terminal 54 protrudes from the second insulating surface 42. Multiple first ends are arranged parallel to each other on the first insulating surface 41 and are located on the same extension line. Multiple second ends are arranged vertically and alternately within the second insulating surface 42. Specifically, the second end of the first connecting terminal 53 is located above, and the second end of the second connecting terminal 54 is located below. It should be noted that "above" here refers to the side of the second insulating surface 42 closest to the first insulating surface 41, and "below" refers to the side of the second insulating surface 42 furthest from the first insulating surface 41.

[0074] In this embodiment, the first connecting terminal 53 is set by the U-shaped structure of the first part 51, which can ensure the depth of the first connecting terminal 53 embedded in the insulating block 4, and the product can be sealed with glue to ensure the pin retention force of the product.

[0075] In summary, the connector provided in this application embodiment, with its connection terminal 5, can ensure the pin retention force requirement while meeting product form requirements.
