The part 72 is buckled with the wire shell buckling part 62, and the lower buckling part 73 of the wire shell is buckled with the wire terminal connector buckling part 63; the wire terminal connector 6 is inserted into the connector through-hole 41, and the lower buckling part 73 of the wire shell is buckled with the first wire terminal shell buckling part 43; the bridging clip 5 abuts the side of the rear end of the riveted wire shell 7; the wire terminal shell 4 is inserted into the board terminal connector 1, the right connecting part 45 of the wire terminal shell passes through the notch 21 of the shielding shell, the second wire terminal shell buckling part 44 is buckled with the board terminal buckle interface 13, and the pin 3 is connected to the terminal 8.

Specifically, the in-vehicle Ethernet connector of the present application consists of two components: a board-side connector assembly and a line-side connector assembly, wherein the board-side connector assembly is assembled by inserting the shielding shell 2 from top to bottom into the shielding shell plug-in hole 12 of the board-side connector 1, and inserting the pin 3 into the pin hole 11; the line-side connector assembly is assembled by inserting the bridging clamp 5 into the clamping groove 42 of the line-end shell 4, the core wire is exposed at the end of the wire 9 after peeling, the core wire is riveted to the terminal 8, and then the terminal 8 is passed from the terminal hole 61 at the rear end of the line-end connector 6 to the front end, and then the front side of the riveted wire shell 7 is riveted to the outer sheath of the wire 9, the upper buckle part 72 and the lower buckle part 73 of the wire shell on the rear side of the riveted wire shell 7 are buckled with the line-end connector 6, and finally the line-end connector 6 is inserted into the line-end shell 4 to be assembled.

It should be noted that, as shown in FIG13 , the bridging clip 5 connects the shielding shell 2 and the rivet shell 7, and these three components can be grounded through the grounding portion under the shielding shell 2. In addition, compared with the shielding shell without a shielding shell or a simple shielding baffle in the prior art, the shielding shell 2 with a U-shaped semi-enclosed structure has greatly enhanced electromagnetic compatibility and anti-electromagnetic interference capabilities, and the shielding shell 2 is cleverly designed - the right shell is provided with a shielding shell notch 21, so that the assembly process is almost the same as before, and the wire end shell 4 is inserted after the shielding shell/board is inserted, and the wire end shell right connection part 45 on the right side of the wire end shell 4 will pass through the shielding shell notch 21, avoiding the problem of complicated assembly process caused by structural improvement.

According to the vehicle-mounted Ethernet connector of the present application, the shielding shell 2 with a U-shaped semi-enclosed structure can greatly enhance the electromagnetic compatibility and anti-electromagnetic interference capabilities while ensuring that the assembly process remains almost unchanged.

According to one embodiment of the present application, the line end connector 6 also includes a plurality of card pin holes 64 arranged on the front end surface, and the upper surface of the cavity where the card pin holes 64 are located has no holes.

According to one embodiment of the present application, observation windows 65 are provided on both sides of the cavity where the card pin hole 64 is located.

Specifically, as shown in Figure 6: the pin hole 64 is used to clamp the terminal 8 and is a window for withdrawing the terminal 8. In the prior art, the pin hole 64 is set on the upper surface, and the spring in the terminal 8 may slide out to the outside and damage the spring when the core wire is pulled. In the present application, the pin hole is set on the front end surface, and the upper surface of the cavity is filled with no holes, so that the terminal can be easily clamped and withdrawn, while avoiding the problem of the spring slipping out.

According to one embodiment of the present application, the snap-on portion 63 of the wire end connector is a pair of square bosses; the snap-on portion 73 under the wire shell is a pair of square holes.

According to one embodiment of the present application, a downward-pointing snap-on hook 74 is provided below the lower snap-on portion 73 of the wire shell, and the first wire end shell snap-on portion 43 is snap-oned with the snap-on hook 74.

Specifically, as shown in Figures 6-7: in the prior art, the line end connector snap-on portion 63 is a single boss; the wire shell lower snap-on portion 73 is a single hole, and the hole position is relatively large, and the larger portion is used to snap-on the first line end shell snap-on portion 43. However, when the applicant was in use and when performing press and stretch tests on the product, he found that the structure in the prior art was not stable, and the snap-on was unstable when the product was shaken. For example, the line end connector 6 would shake and fall out, which would cause the line end connector snap-on portion 63 and the wire shell lower snap-on portion 73 to become loose, making the first line end shell snap-on portion 43 unstable. In the present application, a snap-on hook 74 is provided below the wire shell lower snap-on portion 73, and the snap-on hook 74 can prevent the line end connector snap-on portion 63 from falling out, thereby ensuring that the line end connector 6 and the rivet wire shell 7 are firmly connected.

According to one embodiment of the present application, the buckling portion 72 on the wire shell is an inner buckled and outer convex structure, so that it is tightly held when buckled, and at the same time, the outward protrusion is buckled with the buckling portion 62 of the wire shell.

Specifically, as shown in Figures 2 and 7: the buckling portion 72 on the wire shell in the prior art is only an outward convex structure, which is only used to buckle with the wire shell buckling portion 62, and the buckling portion 72 on the wire shell itself does not have a locking function, resulting in a loose buckle. As shown in Figure 7, in one embodiment of the present application, the buckling portion 72 on the wire shell is designed as an inward buckling and outward convex structure, which can make the buckling portion 72 on the wire shell itself firmly buckled.

According to one embodiment of the present application, the rear end of the terminal 8 is a semi-closed cylindrical structure formed by bending a plane; an upper spring piece 81 is provided at the upper end of the rear end of the terminal 8 extending toward the front end, and a lower spring piece 82 convexly extending downward in a semicircular shape is provided below the upper spring piece 81.

According to one embodiment of the present application, an upper spring sheet groove 83 is provided in the middle of the left side plate of the upper spring sheet 81, and a planar bending structure is provided above the upper spring sheet groove 83 and is integrated with the upper spring sheet 81; a protective plate 84 is provided on the right side of the upper spring sheet 81; and a riveted portion 85 connected to the lower spring sheet 82 is provided at the rear of the protective plate 84.

Specifically, as shown in Figures 8-10: the rear end of the terminal 8 is a semi-closed cylindrical structure, which is convenient for the molding and assembly of the upper spring piece 81 and the lower spring piece 82. In another embodiment, due to the cylindrical structure, the following improvements can be made: 1. The upper spring piece 81 originally had only a single upper end surface that was upturned, but it was changed to a flat bending structure, so that the upper spring piece 81 becomes a flat bending structure with the upper end surface and the left end surface integrated, which can greatly enhance the strength of the upper spring piece 81 and improve its service life; 2. A protective plate 84 is added to the right end surface of the cylinder to protect the upper spring piece 81; 3. The lower spring piece 82 is changed from a two-arm overlap to a riveted reinforcement by a riveted part 85, which improves the strength of the lower spring piece 82.

According to one embodiment of the present application, the front end of the wire end housing 4 is a flat end face, a housing end face boss 46 is provided below the end face, and a clamping groove boss 47 is extended forward from the clamping groove 42. The lengths of the housing end face boss 46 and the clamping groove boss 47 extending forward from the end face are equal.

Specifically, as shown in Figure 5: the wire end shell 4 in the prior art is protruding and the clamping groove 42 and other parts are flat. The end face of this structure is prone to shrinkage and deformation, and it is difficult to make the connecting end face flat when connected to other parts. The present application changes it to a flat end face of the shell, and a boss is provided on the periphery, and the clamping groove is also provided with a boss, which can improve the deformation problem and optimize the product molding quality.

In addition, the elastic secondary lock above the wire end housing 4 can increase the elasticity of the secondary locking force arm, making it easier for the secondary lock to be buckled in.

According to one embodiment of the present application, a serration 22 is provided at the front end or rear end of the left shell or the right shell of the shielding shell 2.

Specifically, as shown in Figure 3: adding serrations 22 can play an anti-slip role and make the structure more stable.

The above-mentioned embodiments are the best implementation schemes for the present application. In addition, the present application can also be implemented in other ways. Any obvious replacements that do not deviate from the concept of the present application are within the protection scope of the present application.

Industrial Applicability

The present invention improves the anti-interference ability and structural strength of the present invention by arranging a board-end connector, a shielding shell of a U-shaped semi-enclosed structure, a pin, a wire-end shell and other structures, can be mass-produced, and has a good market prospect.
