[0075] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0076] In the field of electrical connectors, connectors, as key nodes in the signal transmission chain, play an important role in the signal transmission process. High-frequency signals differ from low-frequency signals in that their rise time becomes very short. Under the strict rise time requirements, in order to ensure the integrity of signal transmission, very strict requirements are placed on the reflection, loss, and anti-interference performance of the signal transmission chain process. Therefore, it is necessary to ensure the impedance continuity of the connector itself and between the connector and the wiring harness. Impedance matching is a very important process in the design and development of connectors. Impedance continuity is an important performance indicator for evaluating connectors. There are many factors that affect the impedance of connectors, such as the material properties, geometry, and fitting clearance of the terminals, outer conductor 3, and insulation 4. Therefore, when developing different connectors, a lot of time and energy is spent on the impedance matching process.

[0077] The calculation formula of the connector characteristic impedance is:

[0078]

[0079] Where R represents resistance, G represents conductance, L represents inductance, C represents capacitance, and ω represents frequency, where R and G are constants. When a high-frequency signal passes through a conductor, ω is very large, and the characteristic impedance can be calculated approximately as follows:

[0080]

[0081] It is known that the factors that affect the characteristic impedance when transmitting high-frequency signals are mainly capacitance and inductance. The capacitance and inductance of the connector are mainly determined by the material and geometry of the inner and outer conductors 3, the dielectric between them, and the gap. Therefore, this application proposes a modular structural design for the outer conductor 3, inner conductor 5, and insulating member 4.

[0082] In the first aspect of the present application, a connector module is provided. Figure 1 , Figure 1 This is a schematic diagram of the structure of the connector module provided in this embodiment. Figure 1 (a) is a schematic structural diagram of the cylindrical portion of the connector provided in this embodiment. Figure 1(b) is a schematic structural diagram of the insulating part and inner conductor of the connector provided in the embodiment. The connector module of this embodiment includes the outer conductor 3, the insulating part 4 and the inner conductor 5. The outer conductor 3 has a cylindrical portion 30 and a covering portion 31. The cylindrical portion 30 has a first accommodating cavity 301 and an installation opening 303 connected to the first accommodating cavity 301. The covering portion 31 is connected to the cylindrical portion 30 and is configured to cover the installation opening 303. The cylindrical portion 30 is cylindrical or square cylindrical. The cylindrical portion 30 is a part of the outer conductor 3. The covering portion 31 is provided on the cylindrical portion 30 to cover the installation opening 303. The cylindrical or square cylindrical structure of the cylindrical portion 30 can be easily installed with other components. Usually, the cylindrical portion 30 is cylindrical and can be better installed with other components. The outer conductor 3 includes at least the cylindrical portion 30 and may also include other components. The covering portion 31 can be provided on the cylindrical portion 30 or on other components of the outer conductor 3, such as the extension portion 32 connected to the cylindrical portion 30. When the outer conductor 3 does not have the extension portion 32, the covering portion 31 is provided on the cylindrical portion 30. The insulating member 4 is at least partially mounted within the first accommodating cavity 301, and the inner conductor 5 is inserted through the insulating member 4. The outer conductor 3, the insulating member 4, and the inner conductor 5 form a modular structure. The outer conductor 3 also has openings for connecting the inner conductor 5 to other components. Typically, the openings are provided at both ends of the outer conductor 3, with one end connected to the PCB and the other end serving as a plug-in connector. The inner conductor 5 is fixedly mounted in the insulating member 4, maintaining a fixed position relative to the insulating member 4. The outer periphery of the insulating member 4 abuts the inner wall of the outer conductor 3, forming a fixed mounting structure. The inner conductor 5 is mounted at the center of the insulating member 4 and the outer conductor 3 to maximize the coaxial connector module.

[0083] In the above structure, the outer conductor 3, the insulating member 4, and the inner conductor 5 are modularly designed to form a standardized device, reducing the number of parts and ensuring a fixed impedance for each connector module, eliminating the need for impedance matching for each product. The first accommodating cavity 301 is used to accommodate the insulating member 4 and the inner conductor 5. The cylindrical portion 30 can have a variety of shapes, such as a cylindrical or square cylinder, and is typically cylindrical. In the above structure, each outer conductor 3 is provided with a covering portion 31 for covering the installation opening 303 for installing the insulating member 4 and the inner conductor 5. After the insulating member 4 and the inner conductor 5 are installed, the covering portion 31 covers the inner conductor 5 in the connector module to provide electromagnetic shielding. The connection between the covering portion 31 and the cylindrical portion 30 can be bent to form a closed connection, with the bending portion 33 being the location. This design ensures that each modular connector module has substantially consistent performance and electromagnetic shielding, reducing the design workload for engineers during later use. As can be appreciated, the covering portion 31 is made of a material that provides the same or similar electromagnetic shielding properties as the outer conductor 3. The covering portion 31 is typically integrally formed with the cylindrical portion 30 and made of the same material. The covering portion 31 is provided on the outer conductor 3. It should be understood that the covering portion 31 can be provided on the cylindrical portion 30 or on other components that comprise the outer conductor 3. In either case, the covering portion 31 is required to cover the mounting opening 303 to achieve electromagnetic shielding. Even after the covering portion 31 is closed, space should be left for the inner conductor 5 to be installed with other components. The insulating member 4 provides electrical isolation and mechanical support in the connector and can be made of PTFE / ceramic suitable for high frequencies. The insulating member 4 can be cylindrical, forming an interference fit with the outer conductor 3 and allowing it to be securely fastened therein. The inner conductor 5 is secured within the cylindrical structure of the insulating member 4. Depending on the material used, the insulating member 4 can be hollow.

[0084] In some embodiments, see Figure 2 、 Figure 3 as well as Figure 4 , a schematic structural diagram of the connector module provided in this embodiment, Figure 2 (a) is a schematic structural diagram of the cylindrical portion of the connector provided in this embodiment. Figure 2 (b) is a schematic structural diagram of the insulating member and inner conductor of the connector provided in the embodiment, Figure 3 This is a schematic diagram of the structure of the outer conductor covering portion provided in this embodiment. Figure 4Schematic diagram of the structure of the insulating member provided in this embodiment being installed in the outer conductor. The connector module provided in this embodiment includes an outer conductor 3, an insulating member 4, and an inner conductor 5. The outer conductor 3 has a cylindrical portion 30 and a covering portion 31. The cylindrical portion 30 has a first accommodating cavity 301 and an installation opening 303 connected to the first accommodating cavity 301. The covering portion 31 is provided on the outer conductor 3 and can cover the installation opening 303. The cylindrical portion 30 is cylindrical; the insulating member 4 is installed in the first accommodating cavity 301; and the inner conductor 5 is provided in the insulating member 4. The outer conductor 3 also includes an extension portion 32 for accommodating the insulating member 4 and the inner conductor 5. The extension portion 32 is installed at a set angle to the cylindrical portion 30. The material used for the extension portion 32 also has an electromagnetic shielding function. The extension portion 32 is configured as an integral structure with the cylindrical portion 30 and the covering portion 31. The extension portion 32 can completely accommodate the insulating member 4 and the inner conductor 5, that is, the insulating member 4 and the inner conductor 5 do not extend out of the space formed by the extension portion 32 and the cylindrical portion 30. However, this does not make it convenient to use or install the insulating member 4 and the inner conductor 5 in conjunction with other components. Therefore, the extension portion 32 usually accommodates the main part of the insulating member 4 and the inner conductor 5, or the extension portion 32 accommodates the entire insulating member 4 and partially accommodates the inner conductor 5, and the two ends of the inner conductor 5 extend out of the extension portion 32 and the cylindrical portion 30 to facilitate use or installation in conjunction with other components. The outer conductor 3, the insulating member 4, and the inner conductor 5 form a modular structure to reduce the number of parts and to stabilize the impedance of the connector module. The cylindrical portion 30 can be in a variety of shapes, such as cylindrical or square cylindrical, and is usually cylindrical. In order to facilitate installation, the extension portion 32 is provided with an installation opening 303 for inserting the insulating member 4 and the inner conductor 5. The installation opening 303 on the extension portion 32 is formed integrally with the installation opening 303 on the cylindrical portion 30. The covering portion 31 can cover the entire installation opening 303. The covering portion 31 is on the cylindrical portion 30 or the extension portion 32. A preferred installation method is that the covering portion 31 is provided on the extension portion 32, such as Figure 2 It should be noted that the inner conductor 5 is fixedly installed in the insulating member 4, so that the position of the inner conductor 5 is fixed relative to the insulating member 4, and the outer periphery of the insulating member 4 abuts against the inner wall of the outer conductor 3 to form a fixed installation structure.

[0085] It is understood that the covering portion 31 is provided on the outer conductor 3, specifically, on the extension portion 32, so that the covering portion 31 covers the mounting opening 303, while also reducing or eliminating any gap between the covering portion 31 and the extension portion 32. The angle between the extension portion 32 and the cylindrical portion 30 can be set at various angles, such as 60°, 70°, 80°, 90°, 100°, 110°, 120°, or 150°, to facilitate installation of the connector module with the housing 2 or PCB. The angle between the extension portion 32 and the cylindrical portion 30 is 90°. The shapes of the insulating member 4 and the inner conductor 5 match those of the outer conductor 3. Specifically, the angle is set to ensure that the outer conductor 3 is compatible with the insulating member 4 and the inner conductor 5, i.e., the shapes of the insulating member 4 and the inner conductor 5 are consistent with those of the outer conductor 3, and to ensure applicability. In a preferred embodiment, the angle between the extension portion 32 and the cylindrical portion 30 is set to 90° or substantially 90°, that is, the outer conductor 3, the inner conductor 5, and the insulating member 4 form an L-shape or a substantially L-shape. This shape design facilitates easy installation of one end of the inner conductor 5 on the PCB after the inner conductor 5 is installed on the connector housing 2, and the other end can be easily installed to form a plug-in connection structure.

[0086] In some embodiments, please refer to Figure 2-Figure 4 The extension portion 32 includes two plate-like structures provided on both sides of the insulating part 4 and the inner conductor 5. The two plate-like structures are arranged parallel to the axis of the cylindrical part 30. The space between the two plate-like structures can just install the insulating part 4 and the inner conductor 5. The two plate-like structures are arranged parallel to the axis, which can facilitate the installation of the insulating part 4 and the inner conductor 5 between the two plate-like structures in the axial direction. The plate-like structure is connected to the cylindrical part 30 as a whole through the arc-shaped part 34. Through the setting of the arc-shaped part 34, the arc-shaped part 34 and the cylindrical part 30 can be smoothly connected. The covering part 31 is provided on the extension portion 32 / the cylindrical part 30. Preferably, the covering part 31 is provided on the extension portion 32. The covering part 31 is connected to the extension portion 32 as a whole through the bending part 33. The covering part 31 is bent by the bending part 33 to cover the installation port 303. Please refer to Figure 2-Figure 4. Specifically, in order to facilitate the installation of the insulating part 4 and the inner conductor 5, the two plate-like structures are installed parallel to each other so that the insulating part 4 can be installed between the two plate-like structures. The cover part 31 is provided at one end of the protective cover 1 of the connector away from the plate-like structure, and the protective cover 1 is described in detail below. The cover part 31 is designed to cover the entire installation opening 303 for inserting the insulating part 4 and the inner conductor 5 for electromagnetic shielding. The cover part 31 can extend to the surroundings to ensure that the installation opening 303 can be covered. It should be noted that when setting the cover part 31 and the extension part 32, it is usually necessary to wrap / cover the part that needs to be electromagnetically shielded for the inner conductor 5, and the part that does not need to be shielded or the part where other components play an electromagnetic shielding role can be selectively not set. Among them, the outer conductor 3 is installed into the insulating part 4 and the inner conductor 5 by first opening the covering part 31, installing the insulating part 4 with the inner conductor 5 inside into the outer conductor 3, and then bending the bending part 33 by external force, so that the covering part 31 is easier to cover through the bending part 33.

[0087] In some embodiments, the covering portion 31 has an enlarged portion on the side facing the cylindrical portion 30, forming a T-shaped structure. The enlarged portion of the covering portion 31 allows the mounting opening 303 to be covered, thereby providing electromagnetic shielding. In particular, when the covering portion 31 is mounted on the extension portion 32, the portion facing the cylindrical portion 30 needs to be enlarged.

[0088] In some embodiments, the extension portion 32 is provided with at least one covering portion 31. The covering portion 31 may be two or more. Usually, the covering portion 31 is provided as one or two pieces. Specifically, the covering portion 31 is provided as two pieces, which are symmetrical or asymmetrical, so as to cover the installation opening 303. The fitting clearance may be a straight line, a broken line, or an arc. Please refer to the attached Figure 5 , detailed description is given below.

[0089] It is understood that when the covering portion 31 is composed of two pieces and arranged symmetrically, the fitting gap is a straight line, and the shape can be two symmetrical inverted L-shaped or wing-shaped, with the upper portion being slightly larger to achieve the desired shielding effect. Figure 3 The shape shown in .

[0090] The covering portion 31 is a piece, so Figure 5As shown in Figure (c), the clearance between the covering portion 31 and the extension portion 32 is primarily created between the cylindrical portion 30 and the extension portion 32. This clearance should be no greater than a predetermined value. After the insulating member 4 and the inner conductor 5 are inserted into the outer conductor 3, an external force is applied to bend the portion connecting the covering portion 31 and the extension portion 32 to form a covering.

[0091] The covering part 31 is composed of two pieces, and the fitting gap is a broken line, such as Figure 5 As shown in Figure (a), it shows the fold line fitting gap between the two covering parts 31.

[0092] The covering part 31 is composed of two pieces, and the fitting clearance is an arc. Figure 5 As shown in Figure (b), the arc fitting gap between the two covering parts 31 is shown.

[0093] When the above-mentioned covering part 31 is composed of two pieces, the fitting clearance is less than 0.2mm. It is understood that in order to ensure a good electromagnetic shielding effect, there should not be an excessively wide gap between the two covering parts 31. The width of the gap between the two covering parts 31 should be less than 0.2mm at all points along the path.

[0094] In some embodiments, the cover portion 31 is composed of two pieces. When closed, the two cover portions 31 have overlapping portions. Figure 5 As shown in Figure (d), it is understood that the covering portion 31 is composed of two overlapping pieces, and when the two covering portions 31 are covered, there is no gap between them, thereby achieving good electromagnetic shielding.

[0095] In some embodiments, see Figure 1-Figure 5 , a number of protrusions 302 are formed on the outer cylindrical surface of the cylindrical portion 30. It should be noted that the protrusions 302 are used to connect the shell 2 and the protective cover 1 of the connector as a whole to form a retaining structure to stabilize the positional relationship between the shell 2 and the protective cover 1 and form a firm installation structure. The protrusions 302 are mainly formed in the matching parts of the cylindrical portion 30 and the inner wall surfaces of the shell 2 and the protective cover 1, and the number should be sufficient. Among them, the installation of the protrusions 302 and the shell 2 and the protective cover 1 should be an interference fit. The protrusions 302 will squeeze the inner wall surfaces of the shell 2 and the protective cover 1, causing the inner wall surfaces of the shell 2 and the protective cover 1 to deform, thereby achieving a more secure connection relationship.

[0096] In addition, the shape and structure of the raised portion 302 can be various, such as conical, hemispherical, wedge-shaped, etc. In a preferred embodiment, the raised portion 302 is wedge-shaped. The wedge is a geometric structure with a triangular or trapezoidal cross-section, which is characterized by being thick at one end and thin at the other end, and generating mechanical locking force or contact pressure through the inclined surface. Its cross-section is usually triangular. It can be understood that in order to make it easier for the cylindrical portion 30 to be installed in the shell 2 and the protective cover 1, the thin end of the raised portion 302 formed on the cylindrical portion 30 is oriented in a direction that is substantially consistent with the direction in which the cylindrical portion 30 is moved by external force during installation, that is, the setting of the raised portion 302 is easy to install and difficult to withdraw. The wedge shape of the raised portion 302 is formed with relatively sharp corners to facilitate puncturing the inner wall surface of the shell 2 and the protective cover 1. After installation, the wedge-shaped protrusion 302 punctures the inner surface of the connector housing 2 and the protective cover 1 to achieve a one-way interference fit effect. When the outer conductor 3 tends to withdraw, the protrusion 302 will have a tendency to expand and a reverse force to prevent the outer conductor 3 from withdrawing.

[0097] In the second aspect of the present application, a connector is provided, which includes at least one connector module as mentioned above, and also includes a shell 2 and a protective cover 1. The shell 2 has a second accommodating cavity 20 for accommodating the connector module, and the protective cover 1 is installed on the shell 2. Thus, we can obtain a modular connector. Accordingly, the connector has all the beneficial effects of the above-mentioned connector module, and the present disclosure will not repeat them here.

[0098] In some embodiments, see Figure 6-Figure 9 The second accommodating cavity 20 has a shape that matches the shape of the connector module. Multiple connector modules, such as two or four or more, can be installed in the connector, and the number and shape of the second accommodating cavity 20 match them.

[0099] Among them, see Figure 8 , which shows a schematic diagram of the installation of the connector module, the housing 2 and the protective cover 1 when there are two ports;

[0100] Among them, see Figure 9 , which shows a schematic diagram of the installation of the connector module, the housing 2 and the protective cover 1 when there are four ports.

[0101] In some embodiments, see Figures 1-8, the outer conductor 3 is connected to the inner wall of the shell 2 and the protective cover 1 through the interference fit of the protrusion 302 to form a fixed connection. Specifically, the cylindrical portion 30 of the outer conductor 3 is cylindrical, and the protrusion 302 is set to a wedge shape, and its wedge shape has a relatively sharp corner. The several protrusions 302 formed on the outer circumference of the outer conductor 3 form an interference fit with the inner wall of the shell 2 and the protective cover 1, so that the protrusion 302 punctures the inner wall of the shell 2 and the protective cover 1. The wedge-shaped protrusion 302 punctures the inner surface of the connector shell 2 and the protective cover 1 to achieve a one-way interference fit effect. When the outer conductor 3 tends to withdraw, the protrusion 302 will have a tendency to expand and a reverse force to prevent the outer conductor 3 from withdrawing, forming a fixed connection.

[0102] In some embodiments, see Figure 6-Figure 7 The protective cover 1 is connected to the shell 2 via a buckle 10. The shell 2 has a matching piece connected to the buckle 10. The buckle 10 can further improve the stability of the connection between the protective cover 1 and the shell 2.

[0103] In some embodiments, see Figure 6 The housing 2 is provided with an extension portion 21 that can extend into the protective cover 1 and fit against the inner wall of the protective cover 1.

[0104] In some embodiments, see Figure 2 、 Figure 6 and Figure 7 , a positioning surface that cooperates with the wall surface of the extension portion 32 is provided in the second accommodating cavity 20. Specifically, an outer surface of the extension portion 32 is a first positioning surface 321, and the second positioning surface 22 that cooperates with the first positioning surface 321 in the second accommodating cavity 20 is provided to facilitate the precise installation of the connector module in the housing 2. In addition, in order to stabilize the covering state of the covering portion 31, the inner wall of the second accommodating cavity 20 is installed in abutment with the bending position of the covering portion 31. When set, the cavity wall of the second accommodating cavity 20 has a function of abutting and limiting the bending position of the covering portion 31 to prevent the gap formed by the covering portion 31 from gradually widening with years of use, and the gap is stable, thereby ensuring that the shielding environment of the entire terminal is basically stable.

[0105] In a third aspect, the present application provides a method for assembling a connector module. Specifically, the inner conductor 5 is installed through the insulating member 4. The insulating member 4 with the inner conductor 5 installed is at least partially installed within the first accommodating cavity 301 through the installation opening 303. The covering portion 31 is bent so that it covers the installation opening 303.

[0106] During assembly, the inner conductor 5 is passed through the insulating member 4, with both ends of the inner conductor 5 extending out of the insulating member 4. The inner conductor 5 is installed at the center of the insulating member 4 and the outer conductor 3. The insulating member 4 is then installed in the first accommodating cavity 301 of the cylindrical portion through the installation opening 303. The installation opening 303 is then completely covered by the covering portion 31 by bending the covering portion 31 to form an electromagnetic shielding effect. After the connector module is assembled, the connector module is then installed in conjunction with the housing 2. The inner conductor 5 is installed at the center of the insulating member 4 and the outer conductor 3 to form a coaxial connector structure, which is more convenient in subsequent use.

[0107] In order to better cover the covering portion 31 , the covering portion 31 is connected to the extending portion 32 as a whole via a bending portion 33 . By bending the bending portion 33 , the covering portion 31 covers the installation opening 303 .

[0108] In some embodiments, the outer conductor 3 includes an extension portion 32 for accommodating the insulating member 4 and the inner conductor 5. The extension portion 32 is installed at a set angle with the cylindrical portion 30. The insulating member 4 and the inner conductor 5 are at least partially placed within the cylindrical portion 30 and the extension portion 32 through the installation openings 303 of the cylindrical portion 30 and the extension portion 32. The cylindrical portion 30 and the extension portion 32 have space to accommodate the insulating member 4 and the inner conductor 5. The insulating member 4 and the inner conductor 5 are installed as close to the cylindrical portion 30 and the extension portion 32 as possible to achieve better electromagnetic shielding effect. Specifically, the extension portion 32 includes two plate-like structures arranged parallel to the axis of the cylindrical portion 30, and there is a space between the two plate-like structures to accommodate the insulating part 4 and the inner conductor 5; the insulating part 4 and the inner conductor 5 are at least partially placed in the space between the two plate-like structures and in the cylindrical portion 30 through the installation opening 303, thereby, the plate-like structure and the cylindrical portion 30 can play an electromagnetic shielding effect.

The positioning surfaces on the wall surface of the extension portion 32 and the inner wall of the housing 2 can better secure the connector module within the housing 2.

[0110] In some embodiments, the connector module assembly method further includes assembling the connector module to a connector including a housing 2; and installing the bent portion 33 against the inner wall of the housing 2. The bent portion 33 is installed against the inner wall of the housing 2 so that the gap between the covering portions 31 does not expand or only expands slightly. During installation, the entire bent portion 33 is placed within the housing 2, and a certain compressive force is applied to the bent portion 33 by the inner wall of the housing 2.

[0111] In some embodiments, the method for assembling a connector module further includes assembling the connector module to a connector, wherein the connector includes a housing 2, and a plurality of raised portions 302 are formed on the outer cylindrical surface of the outer conductor 3. At least one connector module is at least partially installed within the housing 2, so that at least a portion of the raised portions 302 has an interference fit with the inner wall surfaces of the housing 2 and the protective cover 1, forming a retaining connection. The raised portions 302 are used to squeeze and deform the inner wall of the housing 2 and the inner wall of the protective cover 1 to form a stable installation structure.

[0112] In addition, the connector includes a protective cover 1, and the installation method of the connector module, the protective cover 1, and the shell 2 is that at least one of the connector modules is at least partially installed in the shell 2 and the protective cover 1, so that at least part of the protrusion 302 is interference fit with the inner wall surface of the shell 2 and the protective cover 1 to form a fixed connection.

The at least partial installation of the connector module within the housing 2 and the protective cover 1 typically involves installing the portion requiring electromagnetic shielding within the housing 2 and the protective cover 1. The connector module having the raised portion 302 can improve the overall connector's installation stability.
