Description

TECHNICAL FIELD

[0001] The utility model relates to connector technical field, especially a male connector and electronic equipment. BACKGROUND

[0002] The male connector on the market has three different structure interfaces of Type-A, Type-B and Type-C, wherein, compared with Type-A male and Type-B male, Type-C male has smaller volume, and is the latest USB interface appearance standard at present. Meanwhile, Type-C male is an interface type that can be applied to PC main equipment and external equipment (such as mobile phone).

[0003] The conductive shell of the existing Type-C male is generally sleeved on the outside of the insulating main body, therefore, in the process of the end of the conductive shell close to the plug interface being inserted into the matched Type-C female seat, the conductive shell may be locally warped to cause the female seat to be damaged when being inserted into the female seat, thereby affecting the use of the female seat. Type-C male users appear deformation and breakage on the connector in different scenes. SUMMARY

[0004] Therefore, it is necessary to provide a male connector, which can improve the anti-breaking capacity of the male connector and effectively enhance the protection of the male connector by setting a notch structure on the edge of the port of the male connector.

[0005] A male connector, comprising a shell, an insulating shell, a conductive sheet and a circuit board, the shell has opposite first and second ends, and the shell forms a first through hole between the first and second ends along an axial direction, the insulating shell forms a second through hole along the axial direction, the insulating shell is fixed in the first through hole, the conductive sheet is fixed in the second through hole and exposed at the first end, the circuit board is fixed at the second end of the shell, the conductive sheet is electrically connected with the circuit board, and the shell forms a notch at the edge of the second end.

[0006] In the male connector provided in this application, the outer shell has a first end and a second end, and a first through hole is formed axially between the first end and the second end to allow other components to be accommodated inside the shell. An insulating shell forms a second through hole axially, and a conductive piece is fixed to the second through hole. The insulating shell provides mechanical protection and support for the conductive piece, preventing damage to the internal contact points from external impacts. One end of the conductive piece is fixed in the first through hole of the outer shell, and the other end is electrically connected to the circuit board. A notch structure is provided at the port edge of the male connector, allowing the port edge to be divided into multiple independent parts with smaller circumferential widths, rather than a continuous structure with a single circumferential width. This increases the maximum bendable range of each independent part relative to the main body of the outer shell. When the port edge is subjected to bending force and deformed, these parts can bend to a greater extent, thus improving the male connector's resistance to breakage and effectively enhancing its protection. This solves the technical problem of male connectors being prone to bending and breakage in the prior art, and effectively addresses customer complaints about bent or broken male connectors in the data cable industry.

[0007] In one embodiment, the housing includes opposing upper and lower borders, and opposing left and right borders at the second end. The upper, lower, left, and right borders surround and form an opening structure for the first through hole at the second end, and at least one of the upper, lower, left, and right borders has the notch.

[0008] In one embodiment, the edges of the upper frame and the lower frame form notches of different shapes or sizes; and / or the edges of the left frame and the right frame form notches of different shapes or sizes.

[0009] In one embodiment, the left and right frames are arranged in the length direction of the second end, and the circuit board is snapped into the notch in the left and right frames.

[0010] In one embodiment, the notch is rectangular in shape.

[0011] In one embodiment, the notch extends through the housing in a direction perpendicular to the axial direction.

[0012] In one embodiment, the notch extends axially toward the first end.

[0013] In one embodiment, the number of the notches is multiple, and the multiple notches are arranged at circumferential intervals along the second end.

[0014] In one embodiment, the housing includes a front shell and a rear shell connected together, the outer diameter of the rear shell being larger than that of the front shell, the first end being located in the front shell, the second end being located in the rear shell, the insulating shell being fixed in the first through hole corresponding to the front shell, and the circuit board being located in the first through hole corresponding to the rear shell.

[0028] Currently, male connectors on the market come in three different interface structures: Type-A, Type-B, and Type-C. Among them, Type-C male connectors are smaller than Type-A and Type-B connectors and are the latest USB interface standard. Furthermore, Type-C male connectors can be used with both PC host devices and external devices (such as mobile phones). Existing Type-C male connectors typically have the conductive shell fitted onto the outside of the insulating body. Therefore, during the insertion process between the end of the conductive shell near the connector and the compatible Type-C female socket, the conductive shell may partially warp, causing damage to the female socket and affecting its usability. Type-C male connector users have also experienced connector deformation and breakage in different usage scenarios.

[0029] A Type-C male connector refers to the plug portion of a Type-C interface, commonly known as a Type-C plug. It's a type of USB Type-C connector primarily used for connecting to other devices or external hardware. Type-C male connectors are typically designed with a compact plug shape and a reversible insertion design, eliminating concerns about correct orientation and making them more convenient to use. Type-C male connectors support multiple functions such as data transfer, charging, and video output, meeting the needs of various devices. They are highly compatible with various Type-C female connectors and are widely used in digital devices such as mobile phones, tablets, and laptops. Type-C male connectors are often used for connecting cables or external devices, such as charging cables and data cables, and are suitable for the design requirements of various thin and light devices. The working principle of a male connector mainly includes three aspects: physical layer connection, signal transmission, and power consumption control. Regarding physical layer connection, the male connector uses a reverse insertion design; the internal guide pins of the connector automatically identify and adjust during connection, making it more convenient for users and improving connection stability. In terms of signal transmission, it adopts two symmetrical data channels, which can support bidirectional transmission simultaneously. It adopts an ultra-low power consumption mode, which can greatly reduce the energy consumption during the transmission process of the interface. In addition, it has some extra functions, such as being able to connect to devices with video output capabilities to realize multimedia transmission, and supporting audio signal transmission, so that users can better enjoy multimedia entertainment such as music and movies.

[0030] refer to Figures 1-6 To address the aforementioned issues, this application provides a male connector 10, comprising a housing 20, an insulating shell 30, a conductive sheet 40, and a circuit board 50. The housing 20 has a first end 21 and a second end 22, and the housing 20 forms a first through hole 23 axially between the first end 21 and the second end 22. The insulating shell 30 forms a second through hole 31 axially and is fixed in the first through hole 23. The conductive sheet 40 is fixed in the second through hole 31 and exposed at the first end 21. The circuit board 50 is fixed to the second end 22 of the housing 20 and is electrically connected to the conductive sheet 40. A notch 24 is formed at the edge of the second end 22 of the housing 20.

[0031] refer to Figures 1-6In this male connector 10, the male connector 10 includes a housing 20, an insulating shell 30, a conductive plate 40, and a circuit board 50. The housing 20 of the male connector 10 is typically made of various materials, including metal and plastic. Stainless steel housings 20 have high strength and corrosion resistance and are commonly used in the manufacture of connector housings 20. The housing 20 provides protection, shielding against electromagnetic interference while ensuring the male connector 10 interface can receive signal information normally, thus reducing electromagnetic interference to the connector. For example, some housings 20 are made of stainless steel with a bright nickel plating, which is both aesthetically pleasing and durable. Other housings 20 are made of copper and copper alloys. Copper and copper alloys have good electrical and thermal conductivity and are commonly used in the manufacture of connector contacts. For example, pure copper has excellent electrical and thermal conductivity, effectively reducing losses during signal and power transmission. Phosphor bronze is a phosphorus-containing copper-tin alloy with good elasticity and wear resistance, and is often used in connectors that are frequently plugged and unplugged. Beryllium bronze contains beryllium and has high strength and hardness, making it suitable for high-end connectors or connectors used in harsh environments. The plastic housing 20 can be made of ABS plastic (thermoplastic engineering plastic) or polycarbonate plastic. ABS plastic has good insulation properties and high mechanical strength, and is often used for the housing 20 and insulation parts of connectors. Polycarbonate has high transparency, high strength and good dimensional stability, and is suitable for connectors that require observation of the internal conditions.

[0032] See Figure 1 and Figure 2 The outer shell 20 has a first end 21 and a second end 22. A first through hole 23 is formed axially between the first end 21 and the second end 22 in the outer shell 20, allowing the interior of the outer shell 20 to accommodate other components, such as the insulating shell 30, which can be fixed to the first through hole 23. The outer shell 20 can be designed in a straight line. When the outer shell 20 of the male connector 10 is designed as a straight line, while the female connector uses a right-angled bend design, the male and female connectors can fit together more closely during mating. The contact conductor of the male connector 10 is needle-shaped and protrudes, while the contact conductor of the female connector is a hole and is recessed. The insulating shell 30 of the male connector 10 provides insulation protection and position fixation. The insulating shell 30 isolates metal components from other parts, ensuring the safe and stable operation of the circuit. The insulating shell 30 has good insulation performance, effectively isolating electromagnetic interference and current leakage between different circuits, protecting the circuit from damage. In some embodiments, the insulating shell 30 and the outer shell 20 are interference-fitted, which can meet more stable shielding and grounding requirements. The insulating shell 30 secures the connector's position, ensuring mating and dimensional stability of the male connector 10. By fixing the male connector 10 in the correct position, it ensures precise mating of the connector's plug and socket, improving connection reliability.

[0033] In some embodiments, the insulating shell 30 forms a second through hole 31 along the axial direction, and the conductive piece 40 is fixed to the second through hole 31. The insulating shell 30 provides mechanical protection and support for the conductive piece 40, preventing external impact forces from damaging the internal contact points. Especially in harsh working environments, such as high temperature, humid or corrosive environments, the insulating shell 30 can effectively prevent moisture, dust and other contaminants from entering the connector, extending its service life. The conductive piece 40 of the male connector 10 is usually made of copper, copper alloy or other conductive materials. The main function of the conductive piece 40 is to transmit current and signals, ensuring the efficient operation of the male connector 10. The conductive piece 40 is an important component of the connector, ensuring the stability and reliability of the circuit by conducting current and signals from one point to another. The conductive piece 40 in the connector is usually precisely machined and assembled to ensure a tight connection with the connector interface and plug. This design not only ensures the stability of the circuit, but also improves the reliability of the connector.

[0034] The conductive piece 40 is exposed at the first end 21, and the circuit board 50 is fixed to the second end 22 of the housing 20. The conductive piece 40 and the circuit board 50 are electrically connected. The conductive piece 40 of the male connector 10 is electrically connected to the circuit board 50 through the shielding housing 20 and the conductive components. Specifically, one end of the conductive piece 40 is fixed in the first through hole 23 of the housing 20, and the other end is electrically connected to the circuit board 50. In some embodiments, a first pad may be provided on the circuit board 50, and a notch 24 may be provided on the shielding housing 20. During assembly, the circuit board 50 is partially inserted into the notch 24, and the housing 20 is soldered to the first pad, thereby electrically connecting the housing 20 to the first pad. The housing may be designed in a metallic color such as gray or silver, depending on actual needs. The electrical connection between the conductive piece 40 and the circuit board 50 ensures good conductivity between them, and in some embodiments, soldering enhances the stability and reliability of the connection. The conductive pad 40 serves as an electrical connection. In the era of low-speed USB transmission, the conductive pad 40 transmits current and ordinary signals. In the era of high-speed transmission, the conductive pad 40 also plays a role in guiding electromagnetic waves. The contact pad is usually made of copper, copper alloy, or other conductive materials. Its function is to transmit current and signals, ensuring the efficient operation of the male connector 10. In some embodiments, the conductive pad 40 structure includes an insulating body and conductive terminals. The insulating body is used to fix and protect the conductive terminals. The conductive terminals include a contact portion and a solder portion. The contact portion is exposed at the second end 22 of the housing 20, and the solder portion extends beyond the second end 22 of the housing 20. In addition, the design of the housing 20 helps to reduce electromagnetic interference and improve the overall performance of the device. A notch 24 structure is provided at the port edge of the male connector 10, so that the port edge can be divided into multiple independent parts with smaller circumferential widths along the circumference, rather than a continuous structure with a single circumferential width. This can increase the maximum bendable range of each independent part relative to the main body of the shell. When the port edge is deformed by bending force, these parts can bend to a greater extent, which can improve the breakage resistance of the male connector 10 and effectively enhance the protection of the male connector 10. This solves the technical problem of male connector 10 being easy to bend and break in the prior art, and can effectively solve the customer complaints about bending or breaking of male connector 10 in the data cable industry.

[0035] See Figure 2 and Figure 5In some embodiments, the housing 20 includes opposing upper and lower borders 25 and 26, and opposing left and right borders 27 and 28 at the second end 22. Specifically, the upper border 25, lower border 26, left border 27, and right border 28 can surround the opening structure 221 forming the first through hole 23 at the second end 22. The opening structure 221 can be elliptical and can be set to a small size. The opening structure 221 has a relatively rounded shape, and the top and bottom ends of the port are completely the same, allowing for reversible insertion. Unlike traditional USB interfaces, there is no need to carefully distinguish between the forward and reverse directions during use, greatly improving the convenience of use. The circuit board 50 can be fixed inside the housing 20 through the opening structure 221.

[0036] In some embodiments, at least one of the top frame 25, bottom frame 26, left frame 27, and right frame 28 has a notch 24. For example, the left frame 27 has a notch 24, while the top frame 25, bottom frame 26, and right frame 28 do not. Alternatively, in another embodiment, the top frame 25 and bottom frame 26 have notches 24, while the left frame 27 and right frame 28 do not. In one embodiment, the top frame 25, bottom frame 26, and left frame 27 all have notches 24, while the right frame 28 does not. The more notches 24 there are along the circumferential direction on the edge of the second end 22, such as when the top frame 25, bottom frame 26, left frame 27, and right frame 28 each have at least one notch 24, the second end 22 can have a larger bending deformation range in all directions, thereby providing more comprehensive resistance to breakage in all directions. A notch 24 is provided at the edge of the second end 22 of the housing 20 of the male connector 10, so that the edge of the port can be divided into multiple independent parts with smaller circumferential widths along the circumference. Each independent part has a larger bending range than the original continuous structure along the circumference. Therefore, when the edge of the port is deformed by bending force, these parts can be bent to a greater extent, which can improve the fracture resistance of the male connector 10. After assembling the circuit board 50, the fracture resistance can be effectively enhanced.

[0037] See Figure 2 and Figure 5In some embodiments, the edges of the upper frame 25 and the lower frame 26 form notches 24 of different shapes or sizes. The shape and size of the notches 24 can be designed and manufactured according to the actual needs of the product or the user's requirements. By creating notches 24 of different shapes, the circuit board 50 is made more resistant to breakage, and the internal functions are protected by the core assembly, thus resisting crushing and bending damage. In some embodiments, the edges of the left frame 27 and the right frame 28 form notches 24 of different shapes or sizes. Similarly, the shape and size of the notches 24 can be designed and manufactured according to the actual needs of the product or the user's requirements to ensure its reliability and durability in various application scenarios. At the same time, the breakage resistance of the male connector 10 has a crucial impact on its performance and service life.

[0038] In some implementations, the male connector 10 also includes pins, and a capacitive effect exists between the pins and the conductive pad 40, which affects the characteristic impedance of the connector. For example, in a Type-C connector, the pins and conductive pad 40 at the contact points between the male and female connectors form a capacitor. Pins and conductive pad 40 that do not participate in signal transmission also form capacitance. These parasitic capacitances increase capacitive reactance, thus affecting the characteristic impedance of the male connector 10. Pins refer to the protruding pins on the male connector 10. These pins typically correspond to the sockets on the female connector for insertion into the female connector and electrical connection. Male connectors are usually designed as relatively small parts with several pins or conductors, and are often metallic colors such as gray or silver. Some connectors use different colors to identify male and female connectors; for example, red might indicate a male connector and blue a female connector, but this method is not used in all connectors. Male and female connectors typically differ in specifications and dimensions, including the number of pins, spacing, length, and overall connector size. These differences ensure that the male and female connectors can properly mate and achieve a stable electrical connection. Male connectors are typically used at the output end of a circuit or one end of a connecting wire to transmit signals or electrical energy to the female connector.

[0039] See Figure 1 and Figure 2 The left frame 27 and the right frame 28 are arranged in the same direction as the length of the second end 22. The notches 24 in the left frame 27 and the right frame 28 can be rectangular, wherein the notches 24 are parallel to the length of the second end 22. The circuit board 50 can be snapped into the notches 24 in the left frame 27 and the right frame 28 to ensure the stability of the circuit board 50. In some embodiments, the notches 24 are rectangular, or they can be square.

[0040] See Figure 5The notch 24 extends through the housing 20 along the vertical axial direction, allowing the circuit board 50 to be snapped into place. Thus, when the circuit board 50 is subjected to bending force, the opposing second end 22 can more easily deform with the circuit board 50, preventing the circuit board 50 from breaking relative to the second end 22. In some embodiments, the notch 24 extends axially towards the first end 21, housing the circuit board 50 and assembling it with the core to protect the internal functions and resist compressive and bending damage. In some embodiments, there are multiple notches 24, spaced circumferentially along the second end 22, to improve the breakage resistance of the male connector 10.

[0041] The outer casing 20 includes a front casing and a rear casing connected together. The outer diameter of the rear casing is larger than that of the front casing. A step is provided between the rear casing and the front casing. The rear casing and the front casing can be manufactured as a single unit. Specifically, the first end 21 is located in the front casing, the second end 22 is located in the rear casing, the insulating shell 30 is fixed in the first through hole 23 corresponding to the front casing, and the circuit board 50 is located in the first through hole 23 corresponding to the rear casing. The front casing is located at the insertion end of the male connector 10. The front casing is usually designed to be directly inserted into the female connector for convenient device connection. The rear casing is usually fixed to the circuit board 50 or the outer casing 20 of the device. The main function of the rear casing is to fix and protect the internal electronic components, ensuring the stability and reliability of the connection.

[0042] This application also provides an electronic device, which includes the male connector in any of the above embodiments. The electronic device is, for example, a charger, a data cable, a power bank, etc.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
