Description

Technical Field

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

[0002] A connector is an electronic component used to connect circuits, and it realizes the transmission of electrical signals or currents through conductive contacts. A vehicle-mounted Ethernet connector is an electrical connection component designed specifically for the in-vehicle network, and it is mainly used to connect the communication networks of vehicles, such as advanced driver assistance systems, in-vehicle entertainment systems, in-vehicle diagnostic systems, etc. Through the vehicle-mounted Ethernet connector, high-speed data and signals can be transmitted to each device efficiently and stably, ensuring the normal operation of various functions of the vehicle.

[0003] Refer to Figure 1 , the connector includes terminals, cables, shielding covers, terminal fixing blocks, bottom cases, outer cases, and terminal connection blocks. During assembly, first, the ends of two core wires in the cable are crimped to two terminals in a one-to-one correspondence to form a reliable electrical connection; then, the shielding cover and the assembled cable are assembled with the terminals. The function of the shielding cover is to reduce electromagnetic interference and provide mechanical protection, and the end of the shielding cover is fixed to the cable by crimping; then, the terminals are assembled with the terminal fixing blocks. Two channels are provided inside the terminal fixing blocks, and the two terminals are inserted into the two channels in a one-to-one correspondence in sequence. The terminals need to be accurately inserted into the slots on the terminal fixing blocks to ensure the stability of the connection; then, the bottom case and the outer case are assembled, and the terminal connection blocks are arranged between the outer case and the terminal fixing blocks.

[0004] In view of the above-related technologies, during the assembly process of the terminals and the terminal fixing blocks, if the applied force is uneven, it may cause the terminals to deform, thereby affecting the matching between the terminals and the slots; if the positioning of the terminals in the terminal fixing blocks is inaccurate, it may cause the terminals and the slots to be misaligned; and the deformation of the core wires will also hinder the matching between the terminals and the slots. All of these will cause errors between the terminals and the slots, affecting the stability of the connector. Summary of the Invention

[0005] In view of this, the present invention provides a vehicle-mounted Ethernet connector that can be stably locked, aiming to solve the technical problem of errors between the terminals and the slots during the assembly of the terminals and the terminal fixing blocks in the prior art.

[0006] To solve the above technical problems, a vehicle-mounted Ethernet connector capable of stable locking provided by the present invention adopts the following technical solutions: A vehicle-mounted Ethernet connector capable of stable locking includes terminals, cables, a shielding cover, terminal fixing blocks, a bottom shell and a housing; a wire bundling block, which is internally provided with two channels 1 extending along the axial direction of the cable, and two core wires inside the cable sequentially pass through the two channels 1 in a one-to-one correspondence manner. The bottom surface of the wire bundling block is provided with an inclined slot extending in the left-right direction. The inclined slot is located between the two channels 1, and the top surface of the inclined slot extends upward from left to right. A through slot penetrating the wire bundling block in the vertical direction is provided on the right side wall of the inclined slot. 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 inclined slot.

[0007] By adopting the above technical solutions, the wire bundling block is provided, which can optimize the layout of the core wires and protect the core wires. Each core wire is independently inserted into the channel 1 of the wire bundling block, which 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 wire bundling block helps to smoothly assemble the core wires and the shielding cover after the core wires and the terminals are crimped, so that the core wires can smoothly pass through the narrow section of the internal channel 3 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.

[0008] The push rod is provided, and the push rod abuts against the top surface of the inclined slot. After the terminals and the terminal fixing blocks are assembled, the bottom shell is assembled. During the assembly process of the bottom shell, the push rod extends into the inside of the shielding cover. Under the pushing action of the push rod, the wire bundling block moves to the left, which helps to ensure the precise matching of the slots between the terminals and the terminal fixing blocks, thereby reducing the assembly error between the terminals and the terminal fixing blocks. After the bottom shell is assembled, the push rod is inserted into the through slot, which plays a role in locking the wire bundling block and the terminals, and further improves the stability of the device.

[0009] Optionally, after the terminals are crimped with the core wires, the crimping gaps of the terminals face downward. Two convex ribs are connected to the bottom wall of the internal channel 2 of the terminal fixing block, and the two convex ribs are slidably inserted into the crimping gaps of the two terminals in a one-to-one correspondence manner.

[0010] By adopting the above technical solutions, after the terminals are crimped, there are crimping gaps at the crimping positions of the terminals. The downward-facing crimping gaps help to protect the contact parts between the terminals and the core wires. The convex ribs inside the terminal fixing block provide mechanical constraints for the terminals, keep good parallelism between the two terminals, and thus help to ensure the stability of the electrical connection and the consistency of the contact resistance, help to ensure that the terminals maintain a certain position in the terminal fixing blocks, reduce the rotation of the terminals, improve the assembly accuracy, and enhance the stability of the device.

[0011] Optionally, a tail fixing block is slidably inserted between the housing 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, reduce the direct contact between the shielding cover and the outside, thereby reducing electromagnetic interference, helping to maintain the integrity of the signal. The tail fixing block has a limiting effect on the cable, can reduce the situation of cable shaking, helps the cable to maintain a fixed direction and shape, reduces the wear degree of the cable, and improves the stability of the device.

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

[0014] Optionally, the fixing member includes a fixing ring sleeved on the cable. The fixing ring is made of an elastic material. An installation groove extending circumferentially along the cable is formed in 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 installation groove; an outer convex ring is connected to the outer edge of the right end of the shielding cover, and the bottom of the convex ring is provided with an inclined surface one extending upward from left to right, and the outer edge of the left side of the fixing ring is provided with an inclined surface two extending upward from left to right, and the inclined surface two abuts against the inclined surface one.

[0015] By adopting the above technical solution, the tail fixing block is slidably inserted between the housing and the cable. As the tail fixing block approaches the shielding cover, the inclined surface two on the fixing ring abuts against the inclined surface one on the shielding cover. Under the pushing action of the inclined surface one, the fixing ring deforms, and the fixing ring approaches the cable and compresses the cable.

[0016] The deformed fixing ring applies pressure to the cable, thereby effectively fixing the cable, can reduce the situation of cable displacement, improve the stability of the connection, and the close connection between the fixing ring and the cable also helps to improve the electromagnetic shielding effect. The assembly process can be simplified. During the assembly process of the tail fixing block, the fixing ring can grip the cable, and no additional fasteners are required, which is convenient for assembly. When the tail fixing block moves to the right, the fixing ring restores deformation and releases the locking of the cable, which is convenient for maintaining and replacing the device. Compared with the previous way of connecting the shielding cover to the cable by crimping, the setting of the fixing ring enables the components to be reused and improves the fault tolerance rate of the assembly process.

[0017] Optionally, the junction of the inclined surface two and the fixing ring is provided with a fillet.

[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 prolonging the service life of the device. The fillet design helps the inclined surface two to abut against the inclined surface one, enabling the inclined surface two to slide smoothly, and improving the accuracy and efficiency of the assembly.

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

[0020] By adopting the above technical solution, the tip at the bottom of the fixing ring abuts against the outer surface of the cable, making the contact mode between the fixing ring and the cable a line contact. The pressure generated by the line contact is greater, thereby enhancing the grasping force 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 housing and protrudes from the housing.

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

[0023] In summary, the present invention includes the following beneficial technical effects: 1. The wire bundling block is provided, which 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 wire bundling block helps to smoothly assemble the core wires and the shielding cover after the core wires and the terminals are crimped, enabling the core wires to smoothly pass 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; The ejector rod is provided, and the ejector 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 process of the bottom shell, the ejector rod extends into the inside of the shielding cover. Under the pushing action of the ejector rod, the wire bundling block moves to the left, which helps to ensure the precise matching of the slots between the terminal and the terminal fixing block, thereby reducing the assembly error between the terminal and the terminal fixing block; after the bottom shell is assembled, the ejector rod is inserted into the through slot, playing a locking role for the wire bundling block and the terminal, and further enhancing the stability of the device.

[0024] 2. After the terminal is crimped, there is a crimping gap at the crimping position of the terminal. The downward crimping gap helps to protect the contact part between the terminal and the core wire. The convex ribs inside the terminal fixing block provide mechanical constraints for the terminal, keeping good parallelism between the two terminals, which is beneficial to ensuring the stability of the electrical connection and the consistency of the contact resistance, helping to ensure that the terminal maintains a certain position in the terminal fixing block, reducing the rotation of the terminal, improving the assembly accuracy, and enhancing the stability of the device.

[0025] 3. The tail fixing block is provided to close the right end of the connector, reducing the direct contact between the shielding cover and the outside, thereby reducing electromagnetic interference, helping to maintain the integrity of the signal. 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 the wear degree of the cable, and improve the stability of the device.

[0026] 4. The deformed fixing ring applies pressure to the cable, thus effectively fixing the cable, reducing the displacement of the cable, enhancing the connection stability, and the close contact 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 grip the cable, eliminating the need for additional fasteners, and the assembly is convenient.

[0027] 5. The tail fixing block moves to the right, the fixing ring restores its deformation, and the locking of the cable is released, facilitating the maintenance and replacement of the device. Compared with the previous shielding cover connected to the cable by crimping, the setting of the fixing ring enables the components to be reused and improves the fault tolerance rate of the assembly process.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention fall within the scope of protection of the present invention.

[0031] The following will Figure 2 - further Figure 10 describe the present invention in further detail.

[0032] An embodiment of the present invention discloses a vehicle-mounted Ethernet connector that can be stably locked. Refer to Figures 2 to 10 , a vehicle-mounted Ethernet connector that can be stably locked, includes a connector 1, a wire harness block 2, a push rod 3, a convex rib 4, a tail fixing block 5, and a fixing member 6. The wire harness block 2 is used to assist in the assembly process of multiple components of the connector 1 and can improve the assembly efficiency and effect. The tail fixing block 5 is used to close the right end of the connector 1 and lock the position of the cable 12, which can improve the stability of the device.

[0033] Refer to Figure 2 and Figure 3 , the connector 1 includes terminals 11, a cable 12, a shielding cover 13, a terminal fixing block 14, a bottom shell 15, a housing 16, and a terminal connection block 17.

[0034] Refer to Figure 2 and Figure 3 , there are two terminals 11. There are two core wires 121 inside the cable 12. The two terminals 11 are crimped to the two core wires 121 in a one-to-one correspondence. A channel three is opened inside the shielding cover 13. The channel three first contracts and then expands from left to right. After assembly, the terminals 11 and the 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 inside of the shielding cover 13. 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 housing 16 are assembled in place, and the terminal connection block 17 is assembled between the housing 16 and the terminal fixing block 14 to complete the overall assembly of the connector 1.

[0035] Refer to Figure 3 and Figure 4 , two channels one extending axially along the cable 12 are opened inside the wire harness block 2. The two channels one are arranged in parallel in the front-rear direction. The two core wires 121 sequentially pass through the two channels one in a one-to-one correspondence.

[0036] Refer to Figure 3 and Figure 4, during assembly, first assemble the wire bundling block 2 and the two core wires 121, and then assemble the terminal 11 and the core wire 121. The wire bundling block 2 can protect the core wire 121. Each core wire 121 is independently inserted into the first channel of the wire bundling 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 wire bundling block 2 is beneficial to the smooth passing of the terminal 11 and the core wire 121 after crimping through the narrow section of the third channel, weakening the influence 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 the assembly process, and improving the efficiency and effect of the assembly.

[0037] Refer to Figure 4 , Figure 5 and Figure 6 , further, an inclined groove 21 extending in the left-right direction is formed on the bottom surface of the wire bundling block 2. The inclined groove 21 is located between the two first channels, and the top surface of the inclined groove 21 extends upward from left to right. The ejector rod 3 is arranged on the top surface of the bottom shell 15. The ejector rod 3 passes through the through hole 22 at the bottom of the shielding cover 13 and abuts against the top surface of the inclined groove 21.

[0038] Refer to Figure 4 , Figure 5 and Figure 6 , during the assembly process of the bottom shell 15, the ejector 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 ejector rod 3, the wire bundling block 2 moves to the left, causing the core wire 121 and the terminal 11 to move to the left, which helps to ensure the precise matching of the terminal 11 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 enhancing the stability of the device.

[0039] Refer to Figure 4 , Figure 6 and Figure 9 , further, a through groove 23 vertically penetrating the wire bundling block 2 is formed on the right side wall of the inclined groove 21.

[0040] After the bottom shell 15 is assembled, the ejector rod 3 is inserted into the through groove 23, which plays a role in locking the wire bundling block 2 and the terminal 11, reducing the displacement of the wire bundling block 2 and the terminal 11, and further enhancing the stability of the device.

[0041] Refer to Figure 7 , there are two convex ribs 4, and the two convex ribs 4 are arranged in parallel. Two parallel channels 2 are formed in the terminal fixing block 14. The two terminals 11 are inserted into the channels 2 in a one-to-one correspondence manner, and the two convex ribs 4 are fixedly connected to the bottom walls of the channels 2 in a one-to-one correspondence manner.

[0042] Before the terminal 11 is crimped to the core wire 121, the terminal 11 is placed above the core wire 121, with the crimping gap at the crimping position of the terminal 11 facing downward, and the convex rib 4 is slidably inserted into the crimping gap. The convex rib 4 provides mechanical restraint for the terminal 11, keeping a good parallelism between the two terminals 11, which is conducive to ensuring the stability of the electrical connection and the consistency of the contact resistance. The convex rib 4 can provide guidance for the movement of the terminal 11, helping to ensure the smooth movement of the terminal 11, helping to ensure that the terminal 11 maintains a certain position within the terminal fixing block 14, reducing the rotation of the terminal 11, improving the assembly accuracy, and enhancing the stability of the device.

[0043] Refer to 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 outer shell 16 and the cable 12.

[0044] 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, 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, helping to keep the cable 12 in a fixed direction and shape, reducing the wear degree of the cable 12, and improving the stability of the device.

[0045] Refer to Figure 8 , further, the right end of the tail fixing block 5 is located on the right side of the outer shell 16 and protrudes from the outer shell 16. It is convenient to apply force to the tail fixing block 5 and convenient to control the left and right movement of the tail fixing block 5.

[0046] Refer to Figure 8 and Figure 10 , the fixing member 6 is arranged between the tail fixing block 5 and the shielding cover 13, and the function of the fixing member 6 is to fix the position of the cable 12 relative to the tail fixing block 5.

[0047] The fixing member 6 includes a fixing ring 61, a mounting groove 62 and a convex ring 63.

[0048] The fixing ring 61 is sleeved on the cable 12, and the fixing ring 61 is made of an elastic material. Specifically, the manufacturing material of the fixing ring 61 can be selected from polyester, spring steel, phosphor bronze or nitinol alloy, etc. The mounting groove 62 is opened in the left part of the inner wall of the tail fixing block 5, and the mounting groove 62 extends along the circumference of the cable 12. The right side wall of the fixing ring 61 is fixedly connected to the right side wall of the mounting groove 62. The convex ring 63 is fixedly connected to the outer edge of the right end of the shielding cover 13, and the convex ring 63 extends along the circumference of the cable 12. The bottom of the convex ring 63 matches the left side of the fixing ring 61. Specifically, the bottom of the convex ring 63 is provided with an inclined surface 64 extending upward from left to right, and the outer edge of the left side of the fixing ring 61 is provided with an inclined surface 65 extending upward from left to right, and the inclined surface 65 abuts against the inclined surface 64.

[0049] During the process of assembling the tail fixing block 5, the tail fixing block 5 moves to the left, and the second inclined surface 65 abuts against the first inclined surface 64. As the tail fixing block 5 continues to move, under the pushing action of the first inclined surface 64, the second inclined surface 65 moves downward, and the fixing ring 61 deforms. The fixing ring 61 approaches the cable 12 and presses the cable 12 tightly. The deformed fixing ring 61 exerts pressure on the cable 12, thereby effectively fixing the cable 12, reducing the displacement of the cable 12, improving the connection stability, and the close contact between the fixing ring 61 and the cable 12 also helps to improve the electromagnetic shielding effect.

[0050] The assembly process can be simplified. During the assembly of the tail fixing block 5, the fixing ring 61 can grip the cable 12 without additional fasteners, which is convenient for assembly. When the tail fixing block 5 moves to the right, the fixing ring 61 restores its deformation and releases the locking of the cable 12, facilitating the maintenance and replacement of the device. Compared with the previous method of connecting the shielding cover 13 to the cable 12 by crimping, the setting of the fixing ring 61 enables the components to be reused and improves the fault tolerance rate of the assembly process.

[0051] Furthermore, the joint of the second inclined surface 65 and the fixing ring 61 is provided with a rounded corner.

[0052] 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 inclined surface 65 to abut against the first inclined surface 64, enabling the second inclined surface 65 to slide smoothly, improving the assembly accuracy and efficiency.

[0053] Refer to Figure 10 Furthermore, the bottom of the fixing ring 61 is provided with a protrusion with the tip facing the cable 12, and the tip at the bottom of the fixing ring 61 abuts against the outer surface of the cable 12.

[0054] The tip at the bottom of the fixing ring 61 abuts against the outer surface of the cable 12, making the contact mode between the fixing ring 61 and the cable 12 a line contact. The pressure generated by the line contact is greater, thereby enhancing the gripping force of the fixing ring 61 on the cable 12.

[0055] The implementation principle of an in-vehicle Ethernet connector that can be stably locked in an embodiment of the present invention is: Before assembly, first slide the tail fixing block 5 onto the cable 12. Then, make the two core wires 121 inside the cable 12 pass through the two first channels of the wire bundling block 2 in a one-to-one correspondence. The wire bundling block 2 plays a role in protecting and supporting the core wires 121. The two terminals 11 are crimped to the two core wires 121 in a one-to-one correspondence. Before crimping, place the terminal 11 above the core wire 121, make the crimping gap at the crimping position of the terminal 11 face downward, and the convex rib 4 slides and inserts into the crimping gap. The assembled terminal 11 and core wire 121 are inserted into the third channel inside the shielding cover 13. The terminal fixing block 14 can slide and insert into the inside of the shielding cover 13. The terminal 11 matches the slot inside the terminal fixing block 14, and the function of the slot is to limit the position of the terminal 11 relative to the terminal fixing block 14.

[0056] After that, assemble the bottom shell 15. The ejector rod 3 on the bottom shell 15 extends into the inside of the shielding cover 13. Under the pushing action of the ejector rod 3, the wire bundling block 2 moves to the left, causing the core wire 121 and the terminal 11 to move to the left, which helps to ensure the precise matching of the slot of the terminal 11 and the terminal fixing block 14. When the assembly of the bottom shell 15 is completed, the ejector rod 3 is inserted into the through slot 23, and the ejector rod 3 has a locking effect on the wire bundling block 2 and the terminal 11, reducing the displacement of the wire bundling block 2 and the terminal 11.

[0057] Finally, carry out the assembly work of the outer shell 16 and the terminal connection block 17. Slide the tail fixing block 5 to move the tail fixing block 5 to the left between the outer shell 16 and the cable 12. During the leftward 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 deforms. The fixing ring 61 approaches the cable 12 and presses the cable 12 tightly. The terminal connection block 17 is assembled between the outer shell 16 and the terminal fixing block 14.

[0058] Complete the overall assembly of the connector 1.

[0059] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0060] The above is the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
