Description

Technical Field

[0001] The invention relates to the technical field of electrical connection equipment, in particular to a small-sized, high-speed and stable transmission automotive Ethernet connector. Background Art

[0002] The automotive differential high-speed transmission Ethernet connector is a connector designed for high-speed data transmission inside the car. It supports differential signal transmission, which can effectively resist external interference and improve the stability and reliability of signal transmission. This connector usually uses Ethernet technology to achieve high-speed and efficient data transmission, meeting the data exchange needs between various systems inside the car and with external devices.

[0003] When connecting components in a car to Ethernet, they are basically connected through a simple snap-on structure on the connectors of the two docking plugs. As the car is subject to bumps during long-term driving, the connector is prone to shaking in the bumpy environment during long-term driving, which can easily cause axial displacement or loosening of the connector during shaking, affecting the connection stability of the connector during use.

[0004] A plug-in connector is disclosed in a patent document with Chinese patent application number 202410762708.4, application date June 13, 2024, publication date August 20, 2024, and IPC classification number H01R24 / 00, which relates to the field of connector technology and includes a male end component, a female end component and a plug-in module. The male end component includes a male end body, a male end contact and a movable short-circuit component. The male end body is provided with a plug-in cavity and a first accommodating cavity. The male end contact is arranged in the plug-in cavity, and the movable short-circuit component is arranged in the first accommodating cavity. The female end component includes a female end body and a female end contact component. A first insertion hole connected to the first accommodating cavity is provided on the female end body. A limiting portion is convexly provided on the hole wall of the first insertion hole. The plug-in module is movably provided with a locking member, and the locking member has a locking portion engaged with the limiting portion; wherein the plug-in connector has a plug-in state in which the limiting portion and the locking portion are engaged, and a disengaged state in which the limiting portion and the locking portion are disengaged. The technical solution provided by the present invention solves the problem that when the existing plug-in module is directly pulled out from the male end assembly, the short-circuit spring may not be in stable contact when pulled out, increasing the risk of electric shock. Although the technical solution can effectively prevent the plug-in connector from being disengaged through the limit part and the buckle part, the limit part and the buckle part make it difficult for the plug-in connector to be disengaged when it needs to be separated. Summary of the invention

[0005] The purpose of the present invention is to provide a small-sized, high-speed and stable transmission automotive Ethernet connector. By utilizing the structure of the present invention, not only can the automotive Ethernet connector achieve stable transmission, but it can also be easier to separate the automotive Ethernet connector when necessary.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The present invention is a small-sized, high-speed and stable transmission automotive Ethernet connector, comprising a main body and a connecting mechanism, wherein a female positioning sleeve is fixedly connected to the interior of the main body, a gap one is provided between the main body and the female positioning sleeve, a sliding groove two is provided on the inner wall of the female positioning sleeve, the connecting mechanism comprises a main body and a male positioning sleeve arranged in the main body, a gap two is provided between the male positioning sleeve and the main body, and further comprises;

[0008] The elastic mechanism comprises an elastic plate with a middle portion protruding inward, an intermediate plate hinged to the elastic plate, a tilting block 1 hinged to the intermediate plate, and a rotating mechanism for transmitting a rotational force, wherein the elastic plate is slidably connected to the inside of the second slide slot, and the tilting block 1 is slidably connected to the inside of the second slide slot; the rotating mechanism comprises a tilting block 2, a reset elastic member for resetting the tilting block 2, a flexible drag chain connected to a plurality of tilting blocks 2, and a plurality of connecting members connected to the flexible drag chain;

[0009] The supporting mechanism includes a limit frame fixedly connected to the end of the connecting piece away from the flexible drag chain and a support plate slidably connected to the limit frame, and an elastic member is provided between the end of the supporting plate close to the flexible drag chain and the connecting piece; a plurality of auxiliary grooves are opened on the inner wall of the main body, and the outer end of the support plate can be accommodated in the auxiliary groove, the thickness of the outer end of the support plate is smaller than the width of the auxiliary groove, and the main body protrudes from the male positioning sleeve.

[0010] When the above automotive Ethernet connector structure is in use, the connecting mechanism is inserted into the main body to realize signal connection and transmission. When the connecting mechanism is inserted into the main body, first, the main body is inserted into the main body, and the male positioning sleeve has not entered the female positioning sleeve at this time. As the connecting mechanism continues to be inserted, before the male positioning sleeve contacts the elastic plate, the outer end of the support plate enters the auxiliary groove. Then, as the connecting mechanism continues to be inserted, the male positioning sleeve contacts and squeezes the elastic plate. The elastic plate slides in the second slide groove under the squeezing action of the male positioning sleeve, and drives the middle plate and the inclined block one to slide. The flexible drag chain is rotated through the action of the inclined block one and the inclined block two. When the flexible drag chain is in the process of rotating, the side of the auxiliary groove first resists the outer end of the support plate. Therefore, the flexible drag chain drives the connecting member and the limit frame to move, which will cause the support plate to swing. As the flexible drag chain continues to rotate, the outer end of the support plate disengages from the auxiliary groove and continues to swing under the action of the inner wall of the main body, and the outer end of the support plate contacts the inner wall of the main body to increase the friction force, and the support plate is pulled under the action of the elastic member, and the support plate is used to establish a support point between the main body and the female positioning sleeve. Therefore, the elastic plate can increase the elastic friction between the female positioning sleeve and the male positioning sleeve, and at the same time, the support plate is used to establish axial friction on the one hand, and to provide radial support points on the other hand. Therefore, when the connecting mechanism is inserted into the main body, the axial separation and radial runout between the connecting mechanism and the main body are reduced, so that the male terminal on the main body and the female terminal on the connecting mechanism can achieve reliable and stable connection, thereby achieving stable and high-speed transmission of the automotive Ethernet connector signal. When the connecting mechanism needs to be pulled out from the main body, during the pulling out process, the elastic plate will gradually reset, and the middle plate and the tilting block will gradually reset, and the flexible drag chain will reset under the action of the reset elastic member, and the support plate will reset under the action of the elastic member, gradually reducing the force of the support plate on the main body, so that the connecting mechanism is easier to pull out from the main body.

[0011] Furthermore, the inner wall of the female positioning sleeve is provided with more than one set of slide groove groups, each set of slide groove groups includes two slide groove units arranged opposite to each other, and each slide groove unit includes more than one slide groove 2. In this way, the elastic plate can form a symmetrical layout, so that the force exerted by the elastic plate on the female positioning sleeve is uniform.

[0012] Furthermore, an annular groove is provided inside the female positioning sleeve, a strip-shaped through groove connecting the slide groove and the annular groove is provided on the female positioning sleeve, a sliding ring is provided to slide in the annular groove, a short plate is connected to the end of the elastic plate away from the middle plate, and the short plate passes through the strip-shaped through groove and is connected to the sliding ring. This structure can realize the integrated linkage of one end of the elastic plate by connecting multiple short plates into one body through the sliding ring.

[0013] Furthermore, the elastic plate includes a pushing portion, a flat portion and a connecting portion, wherein the pushing portion extends obliquely from one end to the other end, the flat portion extends horizontally, the connecting portion extends obliquely from one end to the other end, and the flat portion is connected between the other end of the pushing portion and the other end of the connecting portion.

[0014] Furthermore, a plurality of slide grooves 1 are provided in the female positioning sleeve, and the plurality of slide grooves 1 are arranged in parallel. A sliding groove is provided on the side of the slide groove 2 close to the slide groove 1, and the side of the sliding groove close to the slide groove 1 penetrates the side wall of the female positioning sleeve, and the tilting block 2 passes through the sliding groove, and the flexible drag chain slides outside the female positioning sleeve, and the tilting block 2 is connected to the flexible drag chain. By providing the sliding groove, the movement of the tilting block 2 can be limited, and the flexible drag chain can be arranged outside the female positioning sleeve, saving space for the flexible drag chain arrangement in the female positioning sleeve.

[0015] Furthermore, a plurality of push blocks are fixedly connected to one side of the flexible drag chain near the sliding ring, a sliding mechanism is provided in the slide groove, the push block can act on the sliding mechanism, and a rubber ring that can act on the body is provided on the sliding mechanism. In this structure, when the flexible drag chain rotates, the push block follows the movement, and the moving push block acts on the sliding mechanism, and the sliding mechanism drives the rubber ring to move outward, so that the rubber ring contacts the inner wall of the body, and the friction between the rubber ring and the inner wall of the body is used to prevent the connection mechanism from being easily separated from the body, and at the same time further reduce the radial runout between the connection mechanism and the body, further improve the reliable and stable connection between the male terminal on the body and the female terminal on the connection mechanism, thereby further improving the stability and high-speed transmission of the automotive Ethernet connector signal.

[0016] Furthermore, the sliding mechanism includes a stopper block, a sliding block, an arc-shaped elastic plate and an elastic tube. The stopper block is fixedly connected inside the first slideway. A sliding block is arranged on the side of the stopper block close to the pusher block. The slideer block is slidably connected inside the first slideway. An arc-shaped elastic plate is arranged between the stopper block and the slideer block. The arc-shaped elastic plate is slidably connected inside the first slideway. An elastic tube is arranged on the arc-shaped elastic plate, and a rubber ring is connected to the elastic tube. In this structure, when the flexible drag chain moves, the pusher block moves, and the pusher block pushes the slideer block to move in the direction of the stopper block. Then, the arc-shaped elastic plate undergoes elastic deformation, thereby driving the elastic tube to move outward. The elastic tube drives the rubber ring to move outward, thereby realizing the linkage effect between the rubber ring and the support plate.

[0017] Furthermore, rotating frames are hinged at both ends of the arc-shaped elastic plate, and the two rotating frames are in an eight-shaped shape. A support is fixed to one end of the rotating frame away from the arc-shaped elastic plate. Arc-shaped elastic sheets are arranged on both sides of the elastic tube on the arc-shaped elastic plate. The support is supported on the upper end of the arc-shaped elastic sheet, and the outer end of the arc-shaped elastic sheet supports the bottom of both sides of the rubber ring. In this structure, when the arc-shaped elastic plate undergoes elastic deformation, the lower ends of the two rotating frames follow the movement, which will push the support to move outward, and the arc-shaped elastic sheet is always supported. The arc-shaped elastic sheet always supports both sides of the rubber ring, so that the rubber ring is more closely in contact with the body, thereby improving the contact reliability between the rubber ring and the body.

[0018] Furthermore, a mounting hole is provided at the position of the rubber ring corresponding to the elastic tube, a flange is provided on the rubber ring at the edge of the mounting hole, an elastic block is provided to slide on the flange, a support column connected to the elastic block is provided in the elastic tube, and an elastic support member is provided between the support column and the arc-shaped elastic plate. With this structure, when the rubber ring moves outward, the elastic block also moves outward under the action of the flange, and the elastic block is closely contacted with the inner wall of the body through the action of the elastic support member, and the elastic support points between the female positioning sleeve and the body are increased, thereby improving the connection reliability between the connection mechanism and the body.

[0019] Furthermore, the elastic block has an annular limiting groove, the flange is located in the annular limiting groove, and the thickness of the flange is less than the height of the annular limiting groove. This structure can not only allow the elastic block to have room for movement, but also limit the movement stroke of the elastic block. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The elastic plate 301 is slidably connected inside the second slide groove 103, and one end of the pushing part 3011 is connected to the limiting rod 3014. The end of the limiting rod 3014 is slidably located in the limiting groove 103a.

[0044] like Figures 9 to 11As shown, it also includes a supporting mechanism 5, which includes a limiting frame 501 fixedly connected to the end of the connecting member 403 away from the flexible drag chain 402 and a supporting plate 502 slidably connected to the limiting frame 501, and an elastic member 503 is provided between the end of the supporting plate 502 close to the flexible drag chain 402 and the connecting member 403, and the elastic member 503 is a spring; the outer end of the supporting plate 502 can be accommodated in the auxiliary groove 201, the thickness of the outer end of the supporting plate 502 is less than the width of the auxiliary groove 201, and the main body 21 protrudes from the male positioning sleeve 202.

[0045] In this embodiment, when the male positioning sleeve 202 is inserted into the interior of the female positioning sleeve 101, the outer wall of the male positioning sleeve 202 will squeeze the pushing parts of the multiple elastic plates 301 inside the second slide groove 103. When the pushing parts of the elastic plates 301 are squeezed, they will push the tilting block 1 303 to slide inside the second slide groove 103 through the middle plate 302.

[0046] The second tilting block 401 is slidably connected to the inside of the second slide groove 103, and the reset elastic member is fixedly connected to the side wall of the second tilting block 401. The end of the reset elastic member away from the second tilting block 401 is fixedly connected to the inner wall of the second slide groove 103.

When the multiple tilting blocks 2 401 on the flexible drag chain 402 are squeezed by the tilting block 1 303, the flexible drag chain 402 will be driven to rotate on the surface of the female positioning sleeve 101.

[0047] like Figures 9 to 13 As shown, a sliding mechanism 6 is arranged inside the slide groove 102, and the sliding mechanism 6 includes a stopper 601 fixedly connected to one end of the slide groove 102, a sliding block 602, an arc-shaped elastic plate 603 and an elastic tube 703. The stopper 601 is provided with a sliding block 602 on one side close to the limit frame 501. The sliding block 602 is slidably connected to the inside of the slide groove 102. An arc-shaped elastic plate 603 is arranged between the stopper 601 and the sliding block 602. The arc-shaped elastic plate 603 is slidably connected to the inside of the slide groove 102. The arc-shaped elastic plate 603 is slidably connected to the inside of the slide groove 102. The two ends of the elastic plate 603 are rotatably connected with rotating frames 604 respectively, and the two rotating frames 604 are in an eight-shaped shape. When the sliding block 602 slides, the resisting block 601 and the sliding block 602 will squeeze and rotate the rotating frames 604 on the arc-shaped elastic plate 603, and make the arc-shaped elastic plate 603 elastically deformed with the middle part bulging outward. The elastic tube 703 is arranged on the arc-shaped elastic plate 603, and a rubber ring 704 is arranged at the outer end of the elastic tube 703, and the elastic tube 703 protrudes on both sides of the rubber ring 704.

[0048] A support member 701 is fixed to one end of the rotating frame 604 away from the arc-shaped elastic plate 603. Arc-shaped elastic sheets 702 are arranged on both sides of the elastic tube 703 on the arc-shaped elastic plate 603. The support member 701 is supported on the upper end of the arc-shaped elastic sheet 702. The outer ends of the arc-shaped elastic sheet 702 support the bottoms of both sides of the rubber ring 704. In this structure, when the arc-shaped elastic plate undergoes elastic deformation, the lower ends of the two rotating frames follow the movement, which will push the support member to move outward, and the arc-shaped elastic sheet is always supported. The arc-shaped elastic sheet always supports both sides of the rubber ring, so that the rubber ring is more closely in contact with the body, thereby improving the contact reliability between the rubber ring and the body.

[0049] A mounting hole is provided at the position of the rubber ring 704 corresponding to the elastic tube 703, a flange 7041 is provided on the rubber ring 704 at the edge of the mounting hole, an elastic block 804 is provided slidingly on the flange 7041, the elastic block 804 has an annular limiting groove 8041, the flange 7041 is located in the annular limiting groove 8041, and the thickness of the flange 7041 is less than the height of the annular limiting groove 8041. This structure can provide the elastic block with space for movement, and at the same time limit the movement stroke of the elastic block. A support column 802 connected to the elastic block 804 is provided in the elastic tube 703, and an elastic support member 801 is provided between the support column 802 and the arc elastic plate, and the elastic support member 801 is a spring. In this structure, when the rubber ring moves outward, the elastic block also moves outward under the action of the flange, and the elastic block is closely contacted with the inner wall of the body through the action of the elastic support member, and the elastic support points between the female positioning sleeve and the body are increased, thereby improving the connection reliability between the connecting mechanism and the body.

[0050] When the above automotive Ethernet connector structure is used, the connection mechanism is inserted into the main body to realize signal connection and transmission. When the connection mechanism is inserted into the main body, first, the main body sleeve of the main body is inserted into gap one, and the male positioning sleeve has not entered the female positioning sleeve at this time. As the connection mechanism continues to be inserted, during this process, the female positioning sleeve will be inserted into gap two. Before the male positioning sleeve contacts the elastic plate, the outer end of the support plate enters the auxiliary groove. Then, as the connection mechanism continues to be inserted, the male positioning sleeve contacts the elastic plate and squeezes the push part of the elastic plate. The push part of the elastic plate slides in the second slide groove under the squeezing action of the male positioning sleeve, and drives the middle plate and the tilting block one to slide. , through the action of the first tilting block and the second tilting block, the flexible drag chain is rotated. When the flexible drag chain is rotating, the side of the auxiliary groove first resists the outer end of the support plate. Therefore, the flexible drag chain drives the connecting piece and the limit frame to move, which will cause the support plate to swing. As the flexible drag chain continues to rotate, the outer end of the support plate is separated from the auxiliary groove and continues to swing under the action of the inner wall of the main body. The outer end of the support plate is used to contact the inner wall of the main body to increase the friction force, and the support plate is pulled under the action of the elastic member to establish a support point between the main body and the female positioning sleeve. Therefore, the elastic friction between the female positioning sleeve and the male positioning sleeve can be increased by the elastic plate, and the axial friction is established by the support plate on the one hand, and the radial support point is provided by the support plate on the other hand. Therefore, when the connecting mechanism is inserted into the main body, the axial separation and radial runout between the connecting mechanism and the main body are reduced, so that the male terminal on the main body and the female terminal on the connecting mechanism can be reliably and stably connected, thereby realizing the stable and high-speed transmission of the automotive Ethernet connector signal. When the connection mechanism needs to be pulled out from the main body, the elastic plate will gradually reset during the pulling process, and the middle plate and the tilting block will gradually reset, and the flexible drag chain will reset under the action of the reset elastic member, and the support plate will reset under the action of the elastic member, gradually reducing the force of the support plate on the main body, so that the connection mechanism is easier to pull out from the main body. When the connection mechanism is inserted into place, the female positioning sleeve squeezes the flat plate part.

[0051] In addition, when the flexible drag chain rotates, the push block follows the movement, and the push block acts on the sliding mechanism after the movement, and the sliding mechanism is used to drive the rubber ring to move outward, so that the rubber ring contacts the inner wall of the body, and the friction between the rubber ring and the inner wall of the body is used to prevent the connection mechanism from being easily separated from the body, and at the same time further reduce the radial runout between the connection mechanism and the body, further improve the reliable and stable connection between the male terminal on the body and the female terminal on the connection mechanism, thereby further improving the stability and high-speed transmission of the automotive Ethernet connector signal. When the arc-shaped elastic plate undergoes elastic deformation, the lower ends of the two rotating frames follow the movement, which will push the support member to move outward, and the arc-shaped elastic sheet is always supported. The arc-shaped elastic sheet always supports both sides of the rubber ring, so that the rubber ring is in closer contact with the body, and the contact reliability of the rubber ring and the body is improved.
