[0033] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific embodiments of the present invention are now described with reference to the accompanying drawings. In the description of the present invention, unless otherwise specified, the meaning of "multiple" is two or more.

[0034] Option 1

[0035] The present invention provides an electrical connector, as shown in Figures 1 to 24, which includes: a sheath 10, a shielding shell 20, an inner insulator 30 and at least one inner conductor terminal 40, the shielding shell 20 includes a shielding tube 21 and a first convex rib 221, the first convex rib 221 is formed separately from the shielding tube 21 and the first convex rib 221 is fixedly connected to the outside of the shielding tube 21; the inner insulator 30 is arranged in the shielding tube 21, and the inner conductor terminal 40 is arranged in the inner insulator 30; the inner wall of the sheath 10 is provided with a first stop step 13, the shielding shell 20 is installed in the sheath 10, and the first convex rib 221 abuts against the first stop step 13.

[0036] The shielding tube 21 in the shielding shell 20 is made of metal, while the first ribs 221 can be made of non-metallic materials, thereby reducing the weight of the shielding shell 20 and lowering both material and manufacturing costs. The shielding tube 21 provides shielding. Furthermore, the first ribs 221 provide positioning between the sheath 10 and the shielding shell 20, ensuring accurate assembly and structural stability. This significantly reduces the overall weight of the electrical connector, facilitating widespread adoption.

[0037] In one embodiment, the shielding shell 20 includes a second rib 222, which is formed separately from the shielding tube 21 and affixed to the exterior of the shielding tube 21. The second rib 222 is located forward of the first rib 221, and a positioning slot 23 is defined between the second rib 222 and the first rib 221. The electrical connector also includes a latch 50, which is inserted into the positioning slot 23 and the latch 11 provided on the sidewall of the housing 10. The shielding shell 20 can be inserted into the housing 10 from the rear end. The first rib 221 prevents the shielding shell 20 from moving forward relative to the housing 10, ensuring that the shielding shell 20 is properly assembled within the housing 10. The latch 50 prevents the shielding shell 20 from moving backward relative to the housing 10, thereby locating the shielding shell 20 longitudinally within the housing 10, facilitating assembly and improving assembly accuracy.

[0038] Furthermore, as shown in Figures 14 to 16, the locking body 50 includes two symmetrically arranged locking cantilevers 51; the inner wall of the locking groove 11 is provided with a locking protrusion block, and the outer side of the locking cantilever 51 is provided with a locking groove 52. The locking body 50 is inserted into the locking groove 11 from top to bottom in Figure 15, and the locking protrusion is snapped into the locking groove 52 to achieve the snap-fit ​​fixation between the locking body 50 and the sheath 10. The front side of the locking cantilever 51 abuts against the second convex rib 222 to perform longitudinal retreat limiting.

[0039] There are many ways to fix the first rib 221 on the shielding tube 21, such as snap-on or screw-on. The second rib 222 can also be fixed to the shielding tube 21 in any feasible way. In one embodiment, the first rib 221 and the second rib 222 are both injection molded outside the shielding tube 21. Furthermore, as shown in Figures 11 to 13, the outer wall of the shielding tube 21 is provided with a plurality of stamped first protrusions 241, and the first protrusions 241 are respectively embedded in the first rib 221 and the second rib 222, which is beneficial to improve the firmness between the first rib 221 and the shielding tube 21, and the firmness between the second rib 222 and the shielding tube 21.

[0040] The shielding tube 21 can be formed using a stamping process. During stamping, a first protruding portion 241 protruding outward is machined on the circumferential area of ​​the shielding tube 21. Then, the first rib 221 and the second rib 222 are injection molded using an integrated injection molding process. During injection molding, the first protruding portion 241 can penetrate into the first and second ribs 221, 222, thereby providing a retaining force between the first and second ribs 221, 222 and the shielding tube 21. The first and second ribs 221, 222 can be made of a resin material, which reduces the overall weight and production cost of the shielding shell 20. The shielding tube 21 is a metal part with relatively good plasticity. The first protruding portion 241 can be formed by stamping and can be a convex bulge or a pre-punctured structure.

[0041] In one embodiment, the inner insulator 30 is provided with a terminal hole 31, and the inner conductor terminal 40 is inserted into the terminal hole 31. The electrical connector also includes a baffle 60, which is mounted on the inner insulator 30, and the front side of the baffle 60 abuts the inner conductor terminal 40. As shown in Figure 8, the inner conductor terminal 40 can be inserted into the terminal hole 31 from the back to the front. After being installed, the inner conductor terminal 40 abuts the stepped portion of the terminal hole 31 and is restricted from further forward movement. Then, the baffle 60 is mounted on the inner insulator 30. The baffle 60 restricts the inner conductor terminal 40 from moving backward relative to the inner insulator 30, thereby achieving longitudinal positioning between the inner conductor terminal 40 and the inner insulator 30 and facilitating assembly of the two. The inner insulator and the inner conductor terminal are limited by the baffle, which facilitates assembly, better ensures assembly quality, and reduces production costs. Specifically, the inner conductor terminal 40 has a variable diameter feature and forms a front stop by abutting against the step portion; the inner conductor terminal 40 forms a rear stop by cooperating with the baffle 60 .

[0042] Furthermore, as shown in Figures 18 and 19, the sidewall of the inner insulator 30 is provided with a mounting groove 32, and the baffle 60 is installed in the mounting groove 32. The baffle 60 and the inner insulator 30 cover the inner conductor terminal 40. The baffle 60 is provided with a clamping block 61, and the inner insulator 30 is provided with a matching clamping groove. The baffle 60 and the inner insulator 30 form a snap fit, and the clamping block 61 is snapped into the clamping groove, so that the inner conductor terminal 40 and the baffle 60 form a rear stop.

[0043] After the inner insulator 30, the inner conductor terminal 40 and the baffle 60 are assembled, they are installed together as a whole in the shielding shell 20. In one embodiment, the outer wall of the shielding tube 21 is provided with a second protrusion 242 formed by stamping, and the front side of the second protrusion 242 abuts against the baffle 60 to form a rear stop structure. Furthermore, the outer wall of the shielding tube 21 is provided with a third protrusion 243 formed by stamping, and the rear side of the third protrusion 243 abuts against the inner insulator 30 to form a front stop structure. The second protrusion 242 and the third protrusion 243 can be formed by stamping, and can be a convex bulge or a pre-punctured structure. Preferably, as shown in Figure 9, the second protrusion 242 and the third protrusion 243 are both pre-punctured structures.

[0044] As shown in FIG4 and FIG7 , a guide plate 301 is provided at the end of the inner insulator 30 , which serves as a guide to facilitate the docking of the inner insulator 30 and the inner conductor terminal 40 when the electrical connector is plugged into a mating connection device.

[0045] In one embodiment, the electrical connector includes a rear cover 70 having a rear cover through-hole 71 for retaining a wire harness 81. The rear cover 70 is mounted on the rear end of the housing 10. By securing the rear cover 70 to the housing 10 and retaining the wire harness 81, radial forces acting on the wire harness 81 are transferred to the housing 10 through the rear cover 70, thereby protecting the wire harness 81 and preventing it from falling out.

[0046] As shown in Figures 1, 2, and 7-9, the back cover 70 is provided with an elastic arm and a skirt structure 732. The skirt structure 732 serves as an assembly stop, and a protrusion 731 is provided on the elastic arm. The housing 10 is provided with a back cover locking hole 12. The wiring harness 81 is pre-inserted through the back cover 70. After the shielding shell 20 and the retained wiring harness 81 are assembled, the back cover 70 is snapped onto the housing 10, so that the skirt structure 732 of the back cover 70 aligns with the end surface of the housing 10, reaching the assembly position. The protrusion 731 then snaps into the back cover locking hole 12, providing secure and reliable radial retention protection. Preferably, the protrusion 731 and skirt structure 732 are circumferentially symmetrical, thus eliminating radial directionality during assembly and facilitating assembly. Furthermore, the back cover 70 structure used by both the male and female electrical connectors is identical, reducing the number of parts, facilitating production, and ultimately lowering production costs.

[0047] As shown in Figures 9 to 12, the shielding shell 20 includes a wire harness crimping portion 211 arranged at the rear end of the shielding tube 21. After the wire harness 81 is inserted into place, the wire harness crimping portion 211 is shrunk and curled by the crimping tool to form a ring, thereby being fixed together with the wire harness 81.

[0048] Furthermore, the rear cover 70 includes a protective tube 72, within which the wire harness crimping portion 211 is at least partially disposed. The protective tube 72 provides safe and reliable radial retention and protection for the wire harness crimping portion 211. The rear cover 70 can be made of an insulating plastic material. The protective tube 72 not only provides radial retention but also wraps around the wire harness crimping portion 211, preventing metal exposure of the shielding shell 20. This protects the connection between the wire harness 81 and the shielding shell 20, preventing the risk of electric shock and improving safety.

[0049] In one embodiment, the electrical connector further includes a wiring harness 81 .

[0050] This electrical connector can be a plug or a socket, meaning it can function as both a male and female terminal. It can also be used as other electrical connection devices. It can be an HSD connector, offering the advantages of safety, reliability, and lightweight. The locking body 50, baffle 60, and rear cover 70 enable universal use of both male and female terminals.
