Description

Technical Field

[0001] The present invention relates to the field of electronic technology, and in particular to a stably locked vehicle-mounted Ethernet connector. Background Art

[0002] Connectors are electronic components used to connect circuits, transmitting electrical signals or currents through conductive contact. Automotive Ethernet connectors are electrical connection components designed specifically for internal automotive networks. They are primarily used to connect to vehicle communication networks, such as advanced driver assistance systems, in-car entertainment systems, and onboard diagnostic systems. Through automotive Ethernet connectors, high-speed data and signals can be efficiently and reliably transmitted to various devices, ensuring the proper functioning of various vehicle functions.

[0003] Reference Figure 1 The connector includes terminals, cables, shielding covers, terminal fixing blocks, bottom shells, outer shells, and terminal connection blocks. During assembly, the ends of the two core wires in the cable are first crimped to the two terminals in a one-to-one correspondence to form a reliable electrical connection; then the shielding cover and the assembled cable are assembled to the terminals. The shielding cover is used to reduce electromagnetic interference and provide mechanical protection. The ends of the shielding cover are fixed to the cable by crimping; then the terminals are assembled to the terminal fixing block. The terminal fixing block has two channels inside, and the two terminals extend into the two channels in a one-to-one correspondence. The terminals need to be accurately inserted into the slots on the terminal fixing block to ensure the stability of the connection; then the bottom shell and outer shell are assembled, and the terminal connection block is located between the outer shell and the terminal fixing block.

[0004] Regarding the above-mentioned related technologies, during the assembly process of the terminal and the terminal fixing block, if the force applied is uneven, the terminal may be deformed, thereby affecting the matching of the terminal and the slot; if the terminal is not accurately positioned in the terminal fixing block, the terminal and the slot may be misaligned; and the deformation of the core wire may also hinder the matching of the terminal and the slot. These will cause errors between the terminal and the slot, affecting the stability of the connector. Summary of the Invention

[0005] In view of this, the present invention provides a stably lockable in-vehicle Ethernet connector, which aims to solve the technical problem in the prior art of errors between terminals and slots when assembling terminals and terminal fixing blocks.

[0006] In order to solve the above technical problems, the present invention provides a stably lockable in-vehicle Ethernet connector, which adopts the following technical solution: a stably lockable in-vehicle Ethernet connector, including a terminal, a cable, a shielding cover, a terminal fixing block, a bottom shell and an outer shell; a wiring harness block, which has two channels one extending along the axial direction of the cable, and the two core wires inside the cable pass through the two channels one in sequence in a one-to-one correspondence. The bottom surface of the wiring harness block is provided with an oblique groove extending in the left and right directions, and the oblique groove is located between the two channels one. The top surface of the oblique groove extends upward from left to right, and the right side wall of the oblique groove is provided with a through groove that penetrates the wiring harness block in the vertical direction. A push rod is provided on the bottom shell, and the push rod passes through the shielding cover and abuts against the top surface of the oblique groove.

[0007] By adopting the above technical solution and installing a cable tie block, the core wire layout can be optimized and protected. Each core wire is independently inserted into channel one of the cable tie block, effectively reducing core wire deformation and maintaining good parallelism between the two core wires. The cable tie block facilitates smooth assembly of the core wires and the shielding cover after the core wires are crimped to the terminals. This allows the core wires to smoothly pass through the narrow section of channel three inside the shielding cover, thereby reducing contact and friction between the core wires and the inner wall of the shielding cover during assembly, improving assembly efficiency and effectiveness.

[0008] A push rod is installed, abutting the top surface of the inclined slot. After the terminals and terminal block are assembled, the bottom shell is assembled. During assembly, the push rod extends into the shielding case. The push rod pushes the wire harness block to the left, helping to ensure a precise fit between the terminals and the slots in the terminal block, thereby reducing assembly errors between the terminals and the terminal block. Once the bottom shell is assembled, the push rod is inserted into the through slot, locking the wire harness block and terminals and further improving the stability of the device.

[0009] Optionally, after the terminal is crimped with the core wire, the crimping gap of the terminal faces downward, and the bottom wall of the second internal channel of the terminal fixing block is connected to two ridges, which are slidably inserted into the crimping gaps of the two terminals in a one-to-one corresponding manner.

[0010] By adopting the above technical solution, after the terminal is crimped, a crimping gap exists at the crimping position of the terminal. The crimping gap faces downward, which helps to protect the contact part of the terminal and the core wire. The ridges inside the terminal fixing block provide mechanical constraints for the terminal, so that the two terminals maintain good parallelism, which is beneficial to ensure the stability of the electrical connection and the consistency of the contact resistance, and helps to ensure that the terminal maintains a certain position in the terminal fixing block, reduces the rotation of the terminal, improves the assembly accuracy, and enhances the stability of the device.

[0011] Optionally, a tail fixing block is slidably inserted between the shell and the cable, and the tail fixing block is sleeved on the cable.

[0012] By adopting the above technical solution, a tail fixing block is provided to close the right end of the connector, reducing direct contact between the shielding cover and the outside, thereby reducing electromagnetic interference and helping to maintain signal integrity. The tail fixing block has a limiting effect on the cable, which can reduce the shaking of the cable, help the cable maintain a fixed direction and shape, reduce cable wear, and improve the stability of the device.

[0013] Optionally, a fixing piece is provided between the tail fixing block and the shielding cover, and the fixing piece is used to fix the tail fixing block and the cable.

[0014] Optionally, the fixing part includes a fixing ring that is sleeved on the cable, the fixing ring is made of elastic material, and a mounting groove extending along the circumference of the cable is opened on the left part of the inner wall of the tail fixing block, and the fixing ring is connected to the right side wall of the mounting groove; the outer edge of the right end of the shielding cover is connected to a convex ring, the bottom of the convex ring is set as a slope 1 extending upward from left to right, and the outer edge of the left side of the fixing ring is set as a slope 2 extending upward from left to right, and the slope 2 is in contact with the slope 1.

[0015] By adopting the above technical solution, the tail fixing block is slidably inserted between the shell and the cable. As the tail fixing block approaches the shielding cover, the second bevel on the fixing ring abuts against the first bevel on the shielding cover. Under the pushing action of the first bevel, the fixing ring is deformed, and the fixing ring approaches the cable and presses the cable.

[0016] The deformed retaining ring applies pressure to the cable, effectively securing it. This reduces cable displacement and improves connection stability. The tight connection between the retaining ring and the cable also contributes to enhanced electromagnetic shielding effectiveness. This simplifies the assembly process. During assembly of the tail fixing block, the retaining ring secures the cable, eliminating the need for additional fasteners and facilitating assembly. When the tail fixing block moves to the right, the retaining ring returns to its original shape, releasing the cable lock and facilitating maintenance and replacement of the device. Compared to previous shielding covers that were crimped to the cable, the retaining ring allows for reuse, improving the assembly process's fault tolerance.

[0017] Optionally, the junction between the second inclined surface and the fixing ring is set as a rounded corner.

[0018] By adopting the above technical solution, the hard contact between the fixing ring and the convex ring is reduced, which is beneficial to reducing the wear of the components and extending the service life of the device. The rounded corner design helps the second bevel to abut against the first bevel, so that the second bevel can slide smoothly, thereby improving the accuracy and efficiency of assembly.

[0019] Optionally, the bottom of the fixing ring is configured as a protrusion with the tip facing the cable, and the tip of the bottom of the fixing ring abuts against the outer surface of the cable.

[0020] By adopting the above technical solution, the tip of the bottom of the fixing ring abuts against the outer surface of the cable, so that the contact mode between the fixing ring and the cable is line contact. The pressure generated by line contact is greater, thereby improving the grip of the fixing ring on the cable.

[0021] Optionally, the right side of the tail fixing block is placed on the right side of the shell and protrudes from the shell.

[0022] By adopting the above technical solution, it is convenient to apply force to the tail fixing block, and it is convenient to use.

[0023] In summary, the present invention has the following beneficial technical effects:

[0024] 1. Setting up the cable bundle block can optimize the layout of the core wires and protect the core wires. It can not only effectively improve the deformation of the core wires, but also maintain good parallelism between the two core wires. The setting of the cable bundle block helps to smoothly assemble the core wires and the shielding cover after the core wires and terminals are crimped. The core wires can pass smoothly through the inside of the shielding cover, thereby reducing the contact and friction between the core wires and the inner wall of the shielding cover during the assembly process, and improving the efficiency and effect of the assembly.

[0025] A push rod is provided, and the push rod abuts against the top surface of the inclined slot; after the terminal and the terminal fixing block are assembled, the bottom shell is assembled. During the assembly of the bottom shell, the push rod extends into the interior of the shielding cover. Under the pushing action of the push rod, the wiring block moves to the left, which helps to ensure that the terminal and the slot of the terminal fixing block are accurately matched, thereby reducing the assembly error between the terminal and the terminal fixing block; after the bottom shell is assembled, the push rod is inserted into the through slot, which locks the wiring block and the terminal, further improving the stability of the device.

[0026] 2. After the terminals are crimped, there is a crimping gap at the crimping position of the terminals. The crimping gap facing downward helps to protect the contact part of the terminal and the core wire. The ridges inside the terminal fixing block provide mechanical constraints for the terminals, so that the two terminals maintain good parallelism, which is beneficial to ensure the stability of the electrical connection and the consistency of the contact resistance. It helps to ensure that the terminals maintain a certain position in the terminal fixing block, reduce the rotation of the terminals, improve the assembly accuracy, and enhance the stability of the device.

[0027] 3. A tail fixing block is set to close the right end of the connector, reducing direct contact between the shielding cover and the outside, thereby reducing electromagnetic interference and helping to maintain signal integrity. The tail fixing block has a limiting effect on the cable, which can reduce the shaking of the cable, help the cable maintain a fixed direction and shape, reduce cable wear, and improve the stability of the device.

[0028] 4. The deformed fixing ring applies pressure to the cable, thereby effectively fixing the cable, reducing cable displacement and improving connection stability. The close connection between the fixing ring and the cable also helps to improve the electromagnetic shielding effect. It can simplify the assembly process. During the assembly of the tail fixing block, the fixing ring can grasp the cable without the need for additional fasteners, making assembly easy.

[0029] 5. The tail fixing block moves to the right, the fixing ring recovers its deformation, and the cable is unlocked, making it easier to maintain and replace the device. Compared with the previous method of connecting the shield cover to the cable by crimping, the setting of the fixing ring allows the components to be reused, improving the fault tolerance of the assembly process.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0042] The following is combined with Figure 2 -Attached Figure 10 The present invention is described in further detail.

[0043] The embodiment of the present invention discloses a vehicle-mounted Ethernet connector that can be stably locked. Figures 2 to 10 A stably lockable automotive Ethernet connector includes a connector 1, a cable harness block 2, a push rod 3, a ridge 4, a tail fixing block 5, and a fixing member 6. The cable harness block 2 assists in assembling the multiple components of the connector 1 and improves assembly efficiency and effectiveness. The tail fixing block 5 closes the right end of the connector 1 and locks the cable 12 in place, improving the stability of the device.

[0044] Reference Figure 2 and Figure 3 The connector 1 includes a terminal 11 , a cable 12 , a shielding cover 13 , a terminal fixing block 14 , a bottom shell 15 , a shell 16 and a terminal connecting block 17 .

[0045] Reference Figure 2 and Figure 3, there are two terminals 11, and two core wires 121 are provided inside the cable 12. The two terminals 11 are crimped with the two core wires 121 in a one-to-one correspondence. A channel three is provided inside the shielding cover 13, and the channel three first contracts and then expands from left to right. The assembled terminals 11 and core wires 121 are inserted into the channel three inside the shielding cover 13. The function of the shielding cover 13 is to reduce electromagnetic interference and provide mechanical protection. The terminal fixing block 14 can be slidably inserted into the interior of the shielding cover 13, and the terminal 11 matches the slot inside the terminal fixing block 14. The function of the slot is to limit the position of the terminal 11 relative to the terminal fixing block 14. Finally, the bottom shell 15 and the outer shell 16 are assembled in place, and the terminal connecting block 17 is assembled between the outer shell 16 and the terminal fixing block 14 to complete the overall assembly of the connector 1.

[0046] Reference Figure 3 and Figure 4 Two channels 1 extending axially along the cable 12 are provided inside the wiring block 2. The two channels 1 are arranged parallel in the front-to-back direction, and the two core wires 121 pass through the two channels 1 in sequence in a one-to-one correspondence.

[0047] Reference Figure 3 and Figure 4 During assembly, first assemble the harness block 2 and the two core wires 121, and then assemble the terminals 11 and the core wires 121. The harness block 2 can protect the core wires 121. Each core wire 121 is independently inserted into channel 1 of the harness block 2, which can not only effectively improve the deformation of the core wire 121, but also maintain good parallelism between the two core wires 121. The setting of the harness block 2 is conducive to the smooth passage of the crimped terminals 11 and the core wires 121 through the narrow section of channel 3, weakening the impact of the deformation of the core wire 121, reducing the contact and friction between the core wire 121 and the inner wall of the shielding cover 13 during assembly, and improving the efficiency and effect of assembly.

[0048] Reference Figure 4 、 Figure 5 and Figure 6 Furthermore, the bottom surface of the wiring harness block 2 is provided with an oblique groove 21 extending in the left-right direction. The oblique groove 21 is located between the two channels 1, and the top surface of the oblique groove 21 extends upward from left to right. The top rod 3 is provided on the top surface of the bottom shell 15. The top rod 3 passes through the through hole 22 at the bottom of the shield cover 13 and abuts the top surface of the oblique groove 21.

[0049] Reference Figure 4 、 Figure 5 and Figure 6During the assembly of the bottom shell 15, the push rod 3 passes through the through hole 22 on the shielding cover 13 and extends into the interior of the shielding cover 13. Under the pushing action of the push rod 3, the wire harness block 2 moves to the left, causing the core wire 121 and the terminal 11 to move to the left, which helps to ensure that the terminal 11 is accurately matched with the slot of the terminal fixing block 14, thereby reducing the assembly error between the terminal 11 and the terminal fixing block 14, helping to improve the assembly accuracy of the device and improve the stability of the device.

[0050] Reference Figure 4 、 Figure 6 and Figure 9 Furthermore, a through slot 23 is formed on the right side wall of the inclined slot 21 and passes through the harness block 2 in the vertical direction.

[0051] After the bottom shell 15 is assembled, the top rod 3 is inserted into the through groove 23, which locks the wiring harness block 2 and the terminal 11, reduces the displacement of the wiring harness block 2 and the terminal 11, and further improves the stability of the device.

[0052] Reference Figure 7 There are two ribs 4, which are arranged in parallel. Two parallel channels 2 are opened in the terminal fixing block 14. The two terminals 11 are inserted into the channel 2 in a one-to-one correspondence. The two ribs 4 are fixedly connected to the bottom wall of the channel 2 in a one-to-one correspondence.

[0053] Before crimping the terminal 11 with the core wire 121, the terminal 11 is placed above the core wire 121, with the crimping gap of the terminal 11 facing downward, and the ridge 4 is slidably inserted into the crimping gap. The ridge 4 provides mechanical constraints for the terminal 11, maintaining good parallelism between the two terminals 11, thereby facilitating the stability of the electrical connection and the consistency of the contact resistance. The ridge 4 can provide guidance for the movement of the terminal 11, helping to ensure smooth movement of the terminal 11 and maintaining a certain position within the terminal fixing block 14, thereby reducing the possibility of rotation of the terminal 11, improving assembly accuracy, and enhancing the stability of the device.

[0054] Reference Figure 3 and Figure 8 The tail fixing block 5 is slidably sleeved on the cable 12 , and the tail fixing block 5 is slidably inserted between the shell 16 and the cable 12 .

[0055] The tail fixing block 5 is used to close the right end of the connector 1, which can reduce the direct contact between the shielding cover 13 and the outside, thereby reducing electromagnetic interference and helping to maintain the integrity of the signal. The tail fixing block 5 has a limiting effect on the cable 12, which can reduce the shaking of the cable 12, help the cable 12 maintain a fixed direction and shape, reduce the wear of the cable 12, and improve the stability of the device.

[0056] Reference Figure 8 Furthermore, the right end of the tail fixing block 5 is located on the right side of the shell 16 and protrudes from the shell 16. It is convenient to apply force to the tail fixing block 5 and to control the left and right movement of the tail fixing block 5.

[0057] Reference Figure 8 and Figure 10 The fixing member 6 is provided between the tail fixing block 5 and the shielding cover 13 . The function of the fixing member 6 is to fix the position of the cable 12 relative to the tail fixing block 5 .

[0058] The fixing member 6 includes a fixing ring 61 , a mounting groove 62 and a protruding ring 63 .

[0059] A fixing ring 61 is sleeved over the cable 12 and is made of an elastic material. Specifically, the material of the fixing ring 61 can be polyester, spring steel, phosphor bronze, or nickel-titanium alloy. A mounting groove 62 is defined in the left portion of the inner wall of the tail fixing block 5. The mounting groove 62 extends along the circumference of the cable 12, and the right side wall of the fixing ring 61 is fixedly connected to the right side wall of the mounting groove 62. A raised ring 63 is fixedly connected to the outer edge of the right end of the shielding cover 13. The raised ring 63 extends along the circumference of the cable 12, and the bottom of the raised ring 63 matches the left side of the fixing ring 61. Specifically, the bottom of the raised ring 63 is formed as a slope 1 64 extending upward from left to right, and the outer edge of the left side of the fixing ring 61 is formed as a slope 2 65 extending upward from left to right, which abuts against the slope 1 64.

[0060] During the assembly of the tail fixing block 5, the tail fixing block 5 moves to the left, and the second bevel 65 abuts against the first bevel 64. As the tail fixing block 5 continues to move, under the pushing action of the first bevel 64, the second bevel 65 moves downward, and the fixing ring 61 is deformed. The fixing ring 61 approaches the cable 12 and presses the cable 12. The deformed fixing ring 61 applies pressure to the cable 12, thereby effectively fixing the cable 12, reducing the displacement of the cable 12, and improving the stability of the connection. The close contact between the fixing ring 61 and the cable 12 also helps to improve the electromagnetic shielding effect.

[0061] The assembly process is simplified. During assembly of the tail fixing block 5, the fixing ring 61 secures the cable 12, eliminating the need for additional fasteners and facilitating assembly. When the tail fixing block 5 moves rightward, the fixing ring 61 returns to its original shape, releasing the lock on the cable 12 and facilitating maintenance and replacement of the device. Compared to conventional methods where the shielding cover 13 is crimped to the cable 12, the fixing ring 61 allows for component reuse, improving the tolerance of the assembly process.

[0062] Furthermore, the junction between the second inclined surface 65 and the fixing ring 61 is configured as a rounded corner.

[0063] Reducing the hard contact between the fixing ring 61 and the convex ring 63 is beneficial to reducing the wear of the components and extending the service life of the device. The rounded corner design helps the second bevel 65 to abut against the first bevel 64, so that the second bevel 65 can slide smoothly, improving the accuracy and efficiency of assembly.

[0064] Reference Figure 10 Furthermore, the bottom of the fixing ring 61 is configured as a protrusion with the tip facing the cable 12 , and the tip of the bottom of the fixing ring 61 abuts against the outer surface of the cable 12 .

[0065] The tip of the bottom of the fixing ring 61 abuts against the outer surface of the cable 12 , so that the contact mode between the fixing ring 61 and the cable 12 is line contact. The pressure generated by line contact is greater, thereby improving the gripping force of the fixing ring 61 on the cable 12.

[0066] The implementation principle of a stably lockable in-vehicle Ethernet connector according to an embodiment of the present invention is as follows:

[0067] Before assembly, first slide the tail fixing block 5 onto the cable 12, and then make the two core wires 121 in the cable 12 pass through the two channels 1 of the harness block 2 in a one-to-one correspondence. The harness block 2 protects and supports the core wires 121. The two terminals 11 are crimped with the two core wires 121 in a one-to-one correspondence. Before crimping, place the terminal 11 above the core wire 121 so that the crimping gap of the terminal 11 crimping position faces downward, and the ridge 4 is slidably inserted into the crimping gap. The assembled terminal 11 and the core wire 121 are inserted into the channel 3 inside the shielding cover 13. The terminal fixing block 14 can be slidably inserted into the interior of the shielding cover 13, and the terminal 11 matches the slot inside the terminal fixing block 14. The function of the slot is to limit the position of the terminal 11 relative to the terminal fixing block 14.

[0068] The bottom shell 15 is then assembled, and the push rod 3 on the bottom shell 15 extends into the interior of the shielding cover 13. Under the pushing action of the push rod 3, the wiring harness block 2 moves leftward, causing the core wire 121 and the terminal 11 to move leftward, helping to ensure that the terminal 11 accurately matches the slot of the terminal fixing block 14. When the bottom shell 15 is assembled, the push rod 3 is inserted into the through slot 23, and the push rod 3 has a locking effect on the wiring harness block 2 and the terminal 11, preventing displacement of the wiring harness block 2 and the terminal 11.

[0069] Finally, the housing 16 and the terminal connection block 17 are assembled, and the tail fixing block 5 is slid to move left between the housing 16 and the cable 12. During the left movement of the tail fixing block 5, the second inclined surface 65 abuts against the first inclined surface 64. Under the pushing action of the first inclined surface 64, the second inclined surface 65 moves downward, and the fixing ring 61 is deformed. The fixing ring 61 approaches the cable 12 and presses the cable 12, and the terminal connection block 17 is assembled between the housing 16 and the terminal fixing block 14.

[0070] The overall assembly of connector 1 is completed.

[0071] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0072] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
