Description

Technical Field

[0001] The present application relates to the technical field of automobile component connection, and in particular to a multi-contact FAKRA connector. Background Art

[0002] In the field of automotive parts connection technology, FAKRA connectors have become an indispensable component in the automotive electronics field due to their significant advantages in high-frequency data security transmission and stable vehicle connection. With the continuous development of automotive intelligence and networking, the performance requirements for FAKRA connectors are becoming increasingly stringent.

[0003] At present, the mainstream FAKRA connectors on the market mostly use a stamped petal-shaped contact shielding shell design. This design did bring certain conveniences to the industry in the early stages. However, with the in-depth application of technology and practical testing, its potential problems have gradually been exposed. Specifically, this type of connector requires laser welding to achieve a stable combination of the shell during the manufacturing process. However, the precise positioning of laser welding points is difficult, and quality problems such as cracking or missing often occur, which seriously affects the structural integrity of the connector. In addition, the traditional stamped petal-shaped shell is prone to deformation after being subjected to force, resulting in poor contact or even open circuit when plugged into the male head. This not only reduces the electrical performance of the connector, but also poses a potential threat to the safe and stable operation of the vehicle. The structural stability of the FAKRA connector is low. Utility Model Content

[0004] In order to improve the structural stability of the FAKRA connector, the present application provides a multi-contact FAKRA connector.

[0005] The present application provides a multi-contact FAKRA connector, which adopts the following technical solution:

[0006] A multi-contact FAKRA connector, comprising:

[0007] main body;

[0008] A limiting member connected to the main body, wherein the limiting member is provided with an access groove;

[0009] The shielding cover comprises a contact spring and a connecting piece, and both are located in the access groove, one end of the contact spring is connected to one end of the main body, the contact spring is arc-shaped, and the protrusion direction is toward the groove center of the access groove, the contact spring is against the limit piece, and the contact spring is distributed along the circumference of the connecting piece;

[0010] An insulating member, the insulating member being located in a space enclosed by the contact spring;

[0011] The terminal is used to provide signal transmission, and the terminal is located in the middle of the insulating member.

[0012] By adopting the above technical solution, when the male connector needs to be inserted into the terminal, the male connector is pushed into the shielding cover, the male connector is abutted against the contact spring, and the limiter provides mechanical support for the shielding cover, thereby reducing the possibility of deformation of the traditional petal-type shielding cover shell after being subjected to force, and improving the structural integrity of the connector; the arc-shaped contact spring design, the protrusion toward the center of the access slot, and the contact with the limiter can improve the accuracy of precise alignment when the male connector is inserted, and even if a single terminal is visible, it does not affect the contact with the male end, thereby improving the stability of the electrical connection; the contact springs are distributed along the circumference of the connector, reducing the direct application of laser welding, reducing quality problems in the welding process, such as cracking and missing, and improving the structural stability of the FAKRA connector.

[0013] Optionally, the connecting piece and the contact spring are integrally formed.

[0014] By adopting the above technical solution, the connector and the contact spring are tightly combined, which reduces gaps and potential connection points during the assembly process. At the same time, reducing the number of joints between components reduces the risk of loosening or breakage due to long-term use or environmental factors, thereby enhancing the stability of the overall structure.

[0015] Optionally, the contact springs are arranged equidistantly along the circumference of the connecting member.

[0016] By adopting the above technical solution, the equidistant arrangement improves the uniform force on the contact springs in the circumferential direction, helps to form a continuous shielding ring, enhances the electromagnetic shielding effectiveness of the shielding cover, and reduces signal interference. When each contact spring contacts the connector, the pressure distribution is consistent, reducing local excessive pressure, optimizing the plugging and unplugging force effect, reducing the possibility of poor contact of the male head, and improving the electrical connection performance.

[0017] Optionally, the limiting member is provided with a limiting groove, and the connecting member is located in the limiting groove.

[0018] By adopting the above technical solution, the limit groove limits the position of the connector, so that the connector is stably positioned in the limit groove, thereby improving the contact stability between the contact spring and the male head. The stable contact reduces the possibility of resistance changes due to vibration or temperature changes, thereby improving the stability of signal transmission and maintaining high-quality electrical connections.

[0019] Optionally, a notch is formed through one side of the connecting piece.

[0020] By adopting the above technical solution, when the male plugs are plugged in, the notch allows the connector to bend or deform within a certain range to adapt to the fit of different shapes or angles, increase the adaptability of the connection, reduce the possibility of the connector cracking or breaking, and improve the structural stability of the connector.

[0021] Optionally, a sheath is provided at one end of the main body close to the contact spring sheet, the sheath is provided with a mounting groove, and the contact spring sheet and the terminal are located in the mounting groove.

[0022] By adopting the above technical solution, the sheath provides physical protection for the internal contact springs and terminals, reduces the intrusion of dust, moisture and other environmental factors, and improves the reliability of electrical connection.

[0023] Optionally, a guide groove is provided on one side of the sheath, and the guide groove is used to guide the insertion terminal when the male plug is plugged in.

[0024] By adopting the above technical solution, the guide groove can guide the male connector to be inserted into the terminal, allowing the operator to easily and correctly insert the male connector into the terminal without using special tools, thereby improving convenience. In complex connectors with multiple pins or contact points, the guide groove simplifies the alignment process.

[0025] Optionally, the sheath is connected to a pressing piece, the pressing piece is provided with a socket for fixing a male head, and an end of the pressing piece away from the socket is connected to an anti-slip piece.

[0026] By adopting the above technical solution, the socket on the pressing piece is designed to receive the male head. When the male head is inserted, the position of the male head can be fixed by pressing the pressing piece, thereby reducing the possibility of accidental loosening of the male head during insertion. The anti-slip piece is located at the end of the pressing piece away from the socket, thereby increasing the friction when the finger contacts it, reducing the possibility of hand slippage when operating the pressing piece, and improving the accuracy and safety of the operation.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. When the male connector needs to be inserted into the terminal, the male connector is pushed into the shielding cover, and the male connector is against the contact spring. The limiter provides mechanical support for the shielding cover, reducing the possibility of deformation of the traditional petal-shaped shielding cover shell after being stressed, and improving the structural integrity of the connector; the arc-shaped contact spring design, the protrusion facing the center of the access slot, and the contact with the limiter can improve the accuracy of precise alignment when the male connector is inserted, even if a single terminal is visible, it does not affect the contact with the male end, and improves the stability of the electrical connection; the contact springs are distributed along the circumference of the connector, reducing the direct application of laser welding, reducing quality problems in the welding process, such as cracking and missing, and improving the structural stability of the FAKRA connector;

[0029] 2. The tight combination of the connector and the contact spring reduces gaps and potential connection points during the assembly process. At the same time, reducing the number of joints between components reduces the risk of loosening or breakage due to long-term use or environmental factors, and enhances the stability of the overall structure;

[0030] 3. Equidistant arrangement improves the uniform force on the contact springs in the circumferential direction, helps to form a continuous shielding ring, enhances the electromagnetic shielding effectiveness of the shielding cover, and reduces signal interference.

[0036] The following is combined with Figure 1-3 This application is described in further detail.

[0037] The embodiment of the present application discloses a multi-contact FAKRA connector.

[0038] Reference Figure 1 and Figure 2A multi-contact FAKRA connector includes a main body 1, a stopper 2, a shielding cover 3, an insulating member 4 and a terminal 5. The main body 1 is used as the core supporting structure of the connector to carry the installation and fixation of other components. One end of the main body 1 is fixedly connected to one end of the stopper 2. The stopper 2 is provided with an access slot 21 on one side close to the main body 1 for guiding and limiting the insertion position of an external connection device. The access slot 21 is circular in shape. The extension direction of the stopper 2 is consistent with the penetration direction of the access slot 21. The shielding cover 3 includes a contact spring 31 and a connector 32, and both are ingenious. The connector 32 is annular in shape, and one end of the connector 32 is fixed to the end of the contact spring 31 away from the main body 1. The contact spring 31 is distributed circumferentially along the connector 32. The contact spring 31 is arc-shaped, and its protruding direction is toward the center of the access groove 21. The contact spring 31 is against the groove wall of the access groove 21. The insulating member 4 is located in the space surrounded by the contact spring 31. The terminal 5 is electrically connected to the external power supply through a cable. The terminal 5 is used to provide signal transmission and is located in the middle of the insulating member 4.

[0039] When the male connector is plugged in, the male connector enters the access slot 21, the contact end is inserted into the terminal 5, the male connector pushes open the contact spring piece 31, and the male connector squeezes the contact spring piece 31. The convex arc of the contact spring piece 31 tends to be flat, so that the contact end of the male connector penetrates into the terminal 5. A limiter 2 is provided on the outside of the contact spring piece 31, and the contact spring piece 31 abuts against the slot wall of the access slot 21. The limiter 2 limits the position of the contact spring piece 31. At the same time, the contact spring piece 31 is fixed circumferentially along the connecting piece 32, so as to strengthen the connection relationship between adjacent contact spring pieces 31, reduce the direct application of laser welding, reduce the possibility of the shielding cover 3 being cracked or deformed due to the displacement of the contact spring piece 31 when the male connector is plugged in, improve the structural stability of the FAKRA connector, and reduce the possibility of poor contact and open circuit due to deformation of the contact spring piece 31 when the male connector is plugged in.

[0040] In order to further reduce the possibility of disconnection between the connector 32 and the contact spring 31 when the male connector is plugged in, the connector 32 and the contact spring 31 are integrally processed and formed, thereby enhancing the integrity of the shielding cover 3 and improving the structural stability of the FAKRA connector.

[0041] The contact springs 31 are arranged equidistantly along the circumference of the connector 32, and the force is evenly applied when the male and female connectors are plugged in, thereby improving the plugging and unplugging force effect. At the same time, it also helps to form a continuous shielding ring to provide all-round shielding of external electromagnetic interference, thereby greatly improving the connector's anti-interference ability and providing a strong guarantee for stable data transmission.

[0042] When plugged into the male connector, the male connector squeezes the contact spring piece 31, and the contact spring piece 31 is convex and abuts against the male connector, and the contact spring piece 31 tends to be flat. When a single contact spring piece 31 is deformed, the male connector can still squeeze the contact spring piece 31, and the male connector and the contact spring piece 31 still abut against each other to achieve electrical connection.

[0043] Reference Figure 1 and Figure 3 In addition, a limiting groove 22 is provided at one end of the groove wall of the access groove 21 away from the main body 1, and the limiting groove 22 is annular. The connecting piece 32 is located in the limiting groove 22. When the male plug is inserted into the terminal 5 for electrical connection, the contact spring 31 is pressed and flattened by force, and the contact spring 31 abuts against the groove wall of the access groove 21, so that the connecting piece 32 moves toward the end away from the main body 1 until the connecting piece 32 abuts against the groove wall of the limiting groove 22, and the limiting groove 22 limits the connecting piece 32. At this time, the contact spring 31 maintains a convex arc shape, and the male plug and the contact spring 31 are pressed and contacted, reducing the possibility of excessive movement of the connecting piece 32, resulting in poor contact between the contact spring 31 and the male plug, so that the male plug continuously applies stable pressure to the contact spring 31, increasing the possibility of contact between the male plug and the contact spring 31, and improving the stability of the electrical connection.

[0044] A notch 321 is formed through the side of the connector 32 away from the contact spring 31, and the connector 32 is in an open ring shape. When the male connector is plugged in, the notch 321 allows the connector 32 to bend or deform within a certain range, thereby enhancing the adaptability of the connection, reducing the possibility of the connector 32 cracking or breaking, and improving the structural stability of the connector. At the same time, it also improves the heat dissipation effect of the connector and reduces the possibility of the connector being heated and degraded under high load.

[0045] A sheath 6 is provided at one end of the main body 1 close to the contact spring piece 31, and a mounting groove 61 is penetrated through one side of the sheath 6. The main body 1 is inserted into the mounting groove 61, and the insertion direction of the main body 1 is opposite to the penetration direction of the mounting groove 61. The side wall of the main body 1 is fixed to the groove wall of the mounting groove 61. The limit member 2, the contact spring piece 31, the insulating member 4 and the terminal 5 are all located in the mounting groove 61, and the side of the limit member 2 away from the main body 1 is also located in the mounting groove 61. The side of the sheath 6 with the mounting groove 61 is protruded with the side of the limit member 2 away from the main body 1 as the reference plane, so as to achieve proper accommodation and protection of the contact spring piece 31, reduce the direct erosion of the external environment to the contact spring piece 31 and the terminal 5, and extend the service life of the connector.

[0046] A guide groove 62 is provided on one side of the installation groove 61 of the sheath 6. There are two guide grooves 62, which are radially arranged along the installation groove 61. The guide groove 62 is connected to the installation groove 61. The guide groove 62 is located at one end of the sheath 6 close to the limit member 2. When the male plug is inserted, the male plug is directed to move along the extension direction of the guide groove 62, so that the male plug can be accurately and quickly connected with the terminal 5 along a predetermined path, thereby improving the user's convenience.

[0047] A plug-in slot 63 is also provided on one side of the sheath 6 where the mounting slot 61 is provided. The plug-in slot 63 is communicated with the mounting slot 61. A pressing piece 7 is connected to the outer wall of the sheath 6. The pressing piece 7 is provided with a socket 71 specifically used for fixing the male plug. The socket 71 is located at one end of the sheath 6 close to the limiter 2. The pressing piece 7 is pressed, and the male plug is inserted into the plug-in slot 63 and the mounting slot 61. The male plug is electrically connected to the terminal 5 and abuts against the contact spring 31. The pressing piece 7 is released, and the male plug is snapped into the plug for snap connection, so that the connection and fixation between the male plug and the connector are more firm and reliable, reducing the possibility of poor electrical connection.

[0048] An anti-slip part 72 is connected to one end of the pressing member 7 away from the socket 71. In the present embodiment, the anti-slip part 72 is a protrusion on the pressing member 7. The anti-slip part 72 and the pressing member 7 are integrally formed, so that the male connector is provided with additional safety during the plugging and unplugging process, thereby improving the stability of the connector when in use.

[0049] The implementation principle of a multi-contact FAKRA connector in an embodiment of the present application is as follows: the contact spring 31 and the connecting piece 32 are integrally formed, and the contact spring 31 is against the limit piece 2. When the male plug is plugged in, the contact spring 31 is not easily deformed or cracked by force, thereby improving the structural stability of the FAKRA connector. The contact spring 31 is arc-shaped, and its protruding direction is toward the groove center of the access groove 21, and the contact springs 31 are arranged equidistantly along the circumference of the connecting piece 32, thereby improving the plugging and unplugging force effect. When plugged in with the male plug, even if a single contact spring 31 is deformed, it will not cause poor contact to the connection between the male plug and the connector, thereby improving the electrical connection stability between the connector and the male plug.
