[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0033] like Figures 1 to 5 As shown, this utility model embodiment provides an in-vehicle Ethernet connector, including a housing body 1, power terminals 2, and a shielding sheet 3.

[0034] The outer shell body 1 has a insertion groove 11 of a certain depth along its length for connecting with the adapter plug. A connecting part 12 is provided on the outer shell body 1 at the middle of the bottom wall of the insertion groove 11. The connecting part 12 is integrally formed with the outer shell body 1. A connecting port 121 of a certain depth is provided on the connecting part 12 along its length. The bottom wall of the insertion groove 11 and the bottom wall of the connecting port 121 are on the same plane.

[0035] The outer shell 1 has a slot 13 on the corresponding installation position of the power terminal 2. The slot 13 is concave, with one side open and the other three sides closed, so that the power terminal 2 is limited on three sides after being installed, avoiding the deformation risk of traditional suspended design. The width of the slot is slightly larger than the width of the power terminal 2, and the depth of the slot is slightly larger than the thickness of the power terminal 2, so as to limit the displacement of the power terminal 2 in the slot 13.

[0036] The groove has protruding stop portions 131 at both ends to limit the lateral movement range of the electrical terminal 2 within the slot 13. The two stop portions 131 on the groove are triangular block structures facing each other, integrally formed with the outer shell body 1. The end of the stop portion 131 away from the opening of the slot 13 has a chamfer 132, specifically 30 degrees, which facilitates the quick insertion of the electrical terminal 2 into the slot 13 and assists in riveting and fixing, improving assembly efficiency and preventing scratches to the electrical terminal 2 during assembly.

[0037] A positioning portion 14 is integrally formed on the shell body 1 below the clamping groove 13. The positioning portion 14 is a block structure protruding away from the insertion groove 11. The positioning portion 14 has a vertical end face stably abutting against the end of the electrical terminal 2 to form a transverse support and prevent the position of the electrical terminal 2 from being deformed during subsequent processing or use.

[0038] The part of the electrical terminal 2 exposed outside the shell body 1 is supported and limited in two directions by the clamping groove 13 and the positioning portion 14, completely solving the problem of terminal suspension caused by the traditional design of digging material to avoid empty space. This structure not only assists in the riveting and fixing of the terminal, but also significantly enhances the impact resistance of the electrical terminal 2, which can still maintain position stability in a high-frequency vibration environment, effectively avoiding the difficulty of inserting the board caused by terminal deformation, adapting to the positional consistency requirements of automated production, and effectively resisting vibration and impact during vehicle travel to avoid signal transmission failure caused by terminal loosening.

[0039] The shell body 1 is also provided with a fixing groove 15 that penetrates from the outside to the insertion groove 11. The shielding sheet 3 is inserted into the fixing groove 15. The groove width of the fixing groove 15 is slightly smaller than the thickness of the shielding sheet 3, and the groove length is also slightly smaller than the length of the shielding sheet 3, thereby forming an interference fit between the shielding sheet 3 and the fixing groove 15 to tightly connect and prevent sliding. The outer surface of the shell body 1 is provided with inclined surfaces around the opening of the fixing groove 15 to provide installation guidance for the shielding sheet 3 and improve installation efficiency.

[0040] A rectangular receiving groove 16 for accommodating the shielding sheet 3 is provided on the side wall of the insertion groove 11. The receiving groove 16 is in communication with the fixing groove 15. The groove depth of the receiving groove 16 is consistent with the depth of the insertion groove 11. The groove width of the receiving groove 16 is greater than the thickness of the shielding sheet 3. When the shielding sheet 3 is inserted, it abuts against the lower end face of the receiving groove 16, thereby achieving installation and positioning.

[0041] The shell body 1 is provided with a separation portion 17 for separating the two groups of electrical terminals 2 to avoid signal interference between the two electrical terminals 2 and improve signal transmission quality. Specifically, the separation portion 17 is integrally formed with the shell body 1. The shell body 1 is provided with a fixing pin 18 for fixing the entire connector to the outside. The fixing pin 18 is a columnar bolt structure to ensure the firmness of the overall installation of the connector.

[0042] The electrical terminal 2 is bent at an angle of 90 degrees and has an overall L shape. One end is an insertion section 21 inserted into the connecting portion 12 and extending into the connecting port 121. The other end is a clamping section 22 clamped in the clamping groove 13 formed in the shell body 1 and abutting against the positioning portion 14 below the clamping groove 13. In this embodiment, the electrical terminal 2 is provided with two groups symmetrically arranged on both sides of the separation portion 17.

[0043] The shielding sheet 3 is inserted into the shell body 1 and extends into the insertion slot 11. Specifically, the shielding sheet 3 is made of stainless steel, has good shielding performance and structural strength. The shielding sheet 3 is provided with a rounded corner 31 at one end close to the opening of the insertion slot 11, which can avoid interference or scratching of the mating components during the insertion process.

[0044] The left and right ends of the shielding sheet 3 are respectively provided with first anti-skid portions 32. The first anti-skid portions 32 at the left and right ends are outwardly protruding structures, and are spaced apart in the length direction. After the shielding sheet 3 is installed in place, the top end surface of the first anti-skid portion 32 abuts against the top end surface of the accommodating groove 16, thereby limiting the shielding sheet 3 from sliding outwards.

[0045] The front and rear ends of the shielding sheet 3 are provided with second anti-skid portions 33, which are outwardly protruding barb-shaped structures. After the shielding sheet 3 is inserted into the fixing groove 15, the second anti-skid portions 33 are in close contact with the side surface of the fixing groove 15, thereby preventing the shielding sheet 3 from sliding.

[0046] The first anti-skid portions 32 and the second anti-skid portions 33 are both used to strengthen the connection between the shielding sheet 3 and the shell body 1, and prevent the shielding sheet 3 from sliding during use.

[0047] A plurality of pins 34 extend outwardly from the shielding sheet 3 to the shell body 1. The pins 34 are uniformly and spaced apart along the length direction of the shielding sheet 3. The other end of the shielding sheet 3 opposite to the pins 34 is provided with a square-shaped limiting portion 35. The thickness of the limiting portion 35 is consistent with the thickness of the shielding sheet 3. Further, the limiting portion 35 is integrally formed with the shielding sheet 3. The shell body 1 is correspondingly provided with a limiting groove 19, which is in communication with the fixing groove 15. The limiting portion 35 cooperates with the limiting groove 19 to prevent the shielding sheet 3 from sliding forward and backward after installation.

[0048] In the present embodiment, the shielding sheet 3 is provided with two groups, which are symmetrically arranged at the two ends of the connecting portion 12.

[0049] The shielding sheet 3 is positioned by the multiple positioning cooperation of the fixing groove 15, the accommodating groove 16, the limiting portion 35 and the limiting groove 19, and is limited by the first and second anti-skid portions 33, so as to ensure that the shielding sheet 3 does not shift or deviate after installation, and to ensure stable shielding performance. The shielding sheet 3 extends into the insertion slot 11 and is adapted to the accommodating groove 16, thereby forming a surrounding shielding for the insertion mating components. Meanwhile, the shielding sheet 3 realizes reliable grounding through the pins 34, can effectively absorb and shield external electromagnetic interference, reduce interference loss in the signal transmission process, and improve the quality of vehicle Ethernet communication.

[0050] The connector assembling process of the embodiment is as follows: firstly, the insertion sections 21 of the two groups of electrical connection terminals 2 are respectively inserted into the connection ports 121 of the connection sections 12, and the clamping sections 22 are clamped into the clamping grooves 13, the end faces of the clamping sections 22 are abutted with the vertical end face of the positioning section 14 and the inner end face of the clamping groove 13 by using the chamfer 132 of one end of the stopper 131 for guiding and positioning, the clamping sections 22 are clamped in the three-face closed structure of the clamping groove 13, and then riveting and reinforcing are performed by the closed structure of the clamping groove 13; then, the two groups of shielding sheets 3 are respectively inserted into the fixed grooves 15 of the shell main body 1, the limiting sections 35 of the shielding sheets 3 are clamped into the limiting grooves 19, the parts extending into the insertion grooves 11 are embedded into the accommodating grooves 16, and positioning is performed through the accommodating grooves 16; finally, the whole connector is fixed to an external mounting seat through the fixing pin 18, the assembling is completed, and the assembling process meets the precision requirement of the automatic production line.
