[0002] The automotive Ethernet connector is a cable connector used in automotive Ethernet systems. It is mainly used to connect automotive electronic control units (ECUs) and sensors to achieve high-speed data transmission and communication between various devices inside the car. Compared with the traditional CAN bus, the automotive Ethernet connector has a higher data transmission rate and lower latency, and can support more automotive application scenarios and more complex automotive electronic systems.
[0003] A high-speed data board-end connector with application number 202311026709 includes an insulator and an inner conductor. The inner conductor is inserted into the square pin hole of the insulator. The inner conductor is a strip-shaped rectangular body.

Since the inner conductor is relatively thin, a large insertion force is required when the inner conductor is inserted into the insulator, which is not easy to assemble.

The vehicle-mounted Ethernet connector is provided with a limit block on the insulator 1, the limit block is connected to the front end of the insulator 1 through an elastic strip, and the limit block is located on the insertion path of the inner conductor to prevent the inner conductor from retreating.

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0041] See also Figure 1-11 In this embodiment, a vehicle-mounted Ethernet connector includes a housing 1, an outer conductor 2, an insulator 3 and an inner conductor 4 from the outside to the inside. The insulator 3 is clamped inside the outer conductor 2, and the inner conductor 4 is accommodated in the insulator 3.
[0042] like Figure 1 and Figure 2 As shown, in the present application, the outer conductor 2 is installed in the housing 1 and the structure is as follows: Figure 1 As shown, the housing 1 is provided with an inner cavity 11, which axially penetrates the housing 1. The outer conductor 2 is inserted into the inner cavity 11 of the housing 1 from the rear end, and the inner cavity 11 is used to restrict the outer conductor 2 from circumferential swing.
[0043] like Figure 3 As shown, the outer conductor 2 is an elliptical tubular structure. When the outer conductor 2 is inserted into the inner cavity 11 that matches it, the outer conductor 2 is restricted from rotating in the circumferential direction.
[0044] The outer circumference of the outer conductor 2 is provided with a shoulder 21, and the inner wall of the inner cavity 11 is provided with a raised stopper 1. At the end of the insertion stroke of the outer conductor 2 into the outer shell 1, the shoulder 21 abuts against one side of the stopper 1 to limit the insertion depth of the outer conductor 2.
[0045] like Figure 4 As shown, a buckle cavity 13 is provided on the outer side of the housing 1, and the buckle cavity 13 is connected with the inner cavity 11, and a buckle cover 12 is clamped in the buckle cavity 13. An elastic card 121 is provided on the buckle cover 12, and a hook 1211 is provided at the lower end of the elastic card 121. A corresponding buckle slot 131 is provided on the inner wall of the buckle cavity 13. When the buckle cover 12 is inserted downward into the buckle cavity 13, the hook 1211 slides into the buckle slot 131, limiting the buckle cover 12 from being disengaged in the reverse direction. The buckle cover 12 is adapted to the buckle cavity 13 around, and the buckle cavity 13 can limit the buckle cover 12 from swinging in a circle.
[0046] There are a plurality of limit posts 122 below the buckle cover 12, and the limit posts 122 extend downward. The waist 22 of the outer conductor 2 shrinks inward relative to the front and rear ends to form a concave position. When the buckle cover 12 is clamped in the buckle cavity 13, the limit posts 122 are inserted downward on the left and right sides of the waist 22 of the outer conductor 2, limiting the outer conductor 2 from slipping out in the reverse direction.
[0047] like Figure 5 As shown, the structure of the insulator 3 is as follows:
[0048] The insulator 3 is divided into two sections separated by front and back, namely the first insulator 31 and the second insulator 32 . The insulator 3 is an integral structure of integral injection molding, so that a connecting piece 33 is formed between the first insulator 31 and the second insulator 32 .
[0049] In the embodiment of the present application, the first insulator 31 is provided with a first channel 301 , and the second insulator 32 is provided with a second channel 302 .
[0050] like Figure 8 As shown, a circle of stopper 41 is provided in the middle of the inner conductor 4. When the inner conductor 4 is inserted into the second insulator 32, the stopper 41 is blocked at the rear end of the second insulator 32 to limit the insertion depth of the inner conductor 4 into the second channel 302.
[0051] like Fig. 9 and Fig.10 As shown, the insulator 1 31 is provided with a limit block 34 , which is connected to the front end of the insulator 1 31 through an elastic strip 35 , and the limit block 34 is located on the insertion path of the inner conductor 4 .
[0052] There are multiple limit blocks 34 , and the limit blocks 34 are symmetrically distributed up and down around the inner conductor 4 .
[0053] During the insertion of the inner conductor 4 from the channel 1 301 to the channel 2 302, the stopper 2 41 of the inner conductor 4 pushes up the limit block 34, and the elastic strip 35 is deformed outwards. Fig.10 As shown, the front end of the second stopper 41 conflicts with the rear end of the second insulator 32. After the inner conductor stopper 41 passes through the limit block 34, the elastic strip 35 recovers its deformation, and the limit block 34 conflicts with the rear end of the second stopper 41, completing the first locking of the inner conductor 4.
[0054] In the embodiment of the present application, the inner diameter of channel one 301 is larger than the outer diameter of gear position two 41, and the inner diameter of channel two 302 is larger than the outer diameter of the head of the inner conductor 4 and smaller than the outer diameter of gear position two 41. Its function is to avoid resistance from the inner wall of channel 30 during the process of inserting the inner conductor 4 into the insulator 3 before inserting into the designated position. The insulator 3 only acts as a bracket to facilitate the assembly between the inner conductor 4 and the insulator 3.
[0055] like Figures 5 to 7 As shown, the insulator 3 is provided with a locking sleeve 5, the locking sleeve 5 is in the shape of a tube sleeve, and the second insulator 32 is inserted into the locking sleeve 5 from the rear end of the locking sleeve 5.
[0056] The left and right sides of the locking sleeve 5 are connected with the insulator 31 by snap-fitting, and the specific structure is: a guide groove 51 is provided at the rear end of the locking sleeve 5, and a guide rib 37 cooperating with the guide groove 51 is provided at the front end of the insulator 31. The guide rib 37 extends forward, and the guide groove 51 extends backward to form an insertion port for the guide rib 37, which facilitates the axial plug-in of the locking sleeve 5 and the insulator 3.
[0057] The front end opening of the locking sleeve 5 is a receiving hole 54. The second insulator 32 is inserted into the locking sleeve 5 from the rear end until the front end of the second insulator 32 is sleeved in the receiving hole 54. The receiving hole 54 is adapted to the front end of the second insulator 32 to limit the circumferential swing of the front end of the second insulator 32.
[0058] The locking sleeve 5 is plugged into the insulator 3 . When the locking sleeve 5 and the insulator 1 31 are completely engaged, the front end of the insulator 2 32 passes through the receiving hole 54 at the front end of the locking sleeve 5 .
[0059] The locking sleeve 5 has a card slot on both sides, and the insulator 3 has a card post on both sides. The card post and the card slot are connected concavely and convexly. The specific implementation structure is as follows: the upper and lower sides of the front end of the card post are respectively provided with a card block 36, which can be inserted into the card position of the inner wall of the card slot.
[0060] In the embodiment of the present application, in order to reduce the possibility of the locking sleeve 5 being lost, there are two concave-convex clamping structures between the clamping column and the clamping position, and the two concave-convex clamping structures are arranged front and back. One concave-convex clamping structure is used for concave-convex clamping at the end of the plugging stroke of the locking sleeve 5 and the insulator 3, and the other concave-convex clamping structure is used for concave-convex clamping after the locking sleeve 5 is separated from the limit block 34.
[0061] The specific implementation structure is as follows: Figure 6As shown, the outer end of the guide groove 51 is provided with a first clamping position 53, and the inner end is provided with a second clamping position 52. The clamping block 36 is first clamped into the first clamping position 53 to achieve the first clamping of the locking sleeve 5 and the insulator 1 31, forming a pre-locking state. At this time, the insulator 2 32 is floated in the locking sleeve 5, which is convenient for assembling the inner conductor 4. Subsequently, the inner conductor 4 and the insulator 3 are assembled, and then the locking sleeve 5 is sleeved. Figure 7 As shown, the clamping block 36 is disengaged from the first clamping position 53, and then the clamping block 36 continues to move forward and is clamped into the second clamping position 52, completing the second clamping connection between the locking sleeve 5 and the insulator 1 31, and forming a locked state.
[0062] When the card block 36 is inserted into the second card position 52, Fig.11 As shown, the limit block 34 slides along the inner wall of the locking sleeve 5, the limit block 34 is squeezed inward by the locking sleeve 5, and abuts against the inner conductor 4, limiting the inner conductor 4 from floating up and down. The inner conductor 4 is tightly held between the limit block 34 and the insulator 31 after being pressed by the limit block 34, and a locking state is formed at this time, completing the secondary locking of the inner conductor 4.
[0063] The function of the first locking position 53 is to facilitate the placement of the locking sleeve 5 and the insulator 3 as a set, and the rear end of the locking sleeve 5 does not contact the limiting block 34 to cause deformation.
[0064] The working principle of the utility model is: the insulator 3 is provided with a channel, the rear end of the channel is an insertion end, the inner diameter of the insertion end is larger than the outer diameter of the second gear 41, and the inner diameter of the front end of the channel is smaller than the outer diameter of the second gear 41. When the second gear 41 is inserted forward into the second channel 302, the limit block 34 slides over the second gear 41 and abuts against the rear side of the second gear 41, so that the second gear 41 is clamped between the front end of the channel and the limit block 34 to limit the axial movement of the inner conductor 4.
[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
