Description

Technical Field

[0001] The present invention belongs to the field of connectors, and in particular relates to a line end connector, an assembly method and a connector component thereof. Background Art

[0002] In the field of autonomous driving, ECU-ECU uses board-side connectors and line-side connectors for line connection.

[0003] The wire-end connectors currently in use do not have a dedicated ground wire contact structure. When connecting, the ground wire needs to be manually connected to the connector housing, which not only reduces construction efficiency but also makes it difficult to ensure construction quality. Existing wire-end connectors usually do not have a waterproof function. If waterproofing is required, an elastic sealing sleeve must be installed on the cable. However, in the prior art, the elastic sealing sleeve is not fixed on the cable. When the cable is inserted into the connector jack, the elastic sealing sleeve is easy to move along the axial direction of the cable. This results in the elastic sealing sleeve needing to be pushed to the appropriate position in the jack after the cable is inserted, which makes the installation complicated and difficult. In addition, the vehicle-mounted connector is required to meet certain vibration resistance performance, and it has higher requirements for connection reliability. The connection reliability of the existing connector needs to be improved. Summary of the Invention

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0055] like Figures 1 to 16As shown, a wire end connector provided in this embodiment includes a metal shell 1, a grounding spring 4, a metal sheet 3, a metal ring 5, an electrical connector 6, an insulating shell 7, and a cable 8. The grounding spring 4 is disposed on the exterior of the metal shell 1 and contacts the metal shell 1. The right side of the metal shell 1 has a first slot 2. The metal sheet 3 is inserted into the first slot 2 and partially extends into the interior of the metal shell 1. The metal sheet 3 contacts the metal shell 1. The metal ring 5 is clamped within the metal shell 1 by the metal sheet 3. The electrical connector 6 is disposed on the left side of the metal shell 1, and the insulating shell 7 is disposed on the exterior of the metal shell 1. The left end of the cable 8 is connected to the electrical connector 6, and the right end extends through the metal ring 5, the metal shell 1, and the insulating shell 7 to the exterior of the insulating shell 7. The provision of the insulating shell 7 leaves the metal shell 1 exposed only at the connection portion 171 with the board-side connector 200. The metal braid 9 of the cable 8 is folded back to contact or connect with the inner wall of the metal ring 5. The grounding effect is achieved through the electrical connection between the metal braided layer 9-metal ring 5-metal sheet 3-metal shell 1-grounding spring 4. After assembly, there is no need to manually connect the ground wire during use. When in use, after the line end connector is inserted into the board end connector 200, the grounding spring 4 contacts the metal shell of the board end connector 200.

[0056] The metal ring 5 has a gap 51 to facilitate being pressed by the metal sheet 3 .

[0057] There are two sets of metal sheets 3, each consisting of two metal sheets 3 positioned opposite each other. Specifically, the middle portion of each metal sheet 3 has a second retaining groove 31. Each set of metal sheets 3 forms an annular retaining hole 32 for securing the metal ring 5. The front and rear ends of each metal sheet 3 have protrusions 33 that engage the first retaining groove 2. The two sets of metal sheets 3 provide enhanced shielding. During installation, align the metal sheet 3 with the first retaining groove 2, insert it, and secure the metal ring 5. Once installed, the outer wall of the metal sheet 3 is flush with the outer wall of the metal shell 1.

[0058] The grounding spring 4 is a bent metal spring structure that is snapped together end to end and is sleeved onto the outer wall of the metal shell 1. Specifically, the grounding spring 4 defines four first openings 41 and ten second openings 42. The walls of the first openings 41 are connected to first spring portions 43. One end of the first spring portion 43 is free and bends inward to abut against the metal shell 1, ensuring close contact with the metal shell 1. The walls of the second openings 42 are connected to second spring portions 44. One end of the second spring portion 44 is free and bends outward to abut against the metal shell of the board-side connector 200, ensuring close contact with the metal shell of the board-side connector 200 and improving electrical stability.

[0059] The metal shell 1 also includes an insulating fixture 10 for securing the metal ring 5. The insulating fixture 10 is disposed within the metal shell 1. The insulating fixture 10 has a first through-hole 101 through which the metal ring 5 passes. The provision of the insulating fixture 10 improves the installation stability of the metal ring 5. In this embodiment, the insulating fixture 10 is made of nylon or LCP. Specifically, the insulating fixture 10 is located between the left metal sheet 3 and the first outer film 23.

[0060] It also includes a waterproof pad 11, a clamping seat 12, and a waterproof ring 13. The waterproof pad 11 is arranged on the outer side wall of the insulating shell 7, and the clamping seat 12 is connected to the insulating shell 7. In this embodiment, the waterproof pad 11 is clamped to the right outer side wall of the insulating shell 7, and the cable 8 passes through the waterproof pad 11 and the clamping seat 12 and extends to the outside of the clamping seat 12. The waterproof ring 13 is arranged on the outside of the insulating shell 7 and is located on the left side of the insulating shell 7. The waterproof ring 13 and the waterproof pad 11 of this embodiment are both made of rubber, which is elastic and has a good waterproof sealing effect. By setting the waterproof ring 13 on the insulating shell 7, when connected to the board-end connector 200, a sealing and waterproof effect is achieved at the connection point. The waterproof pad 11 is clamped and fixed to the right end of the insulating shell 7 by the clamping seat 12, and the position where the cable 8 extends out of the insulating shell 7 is sealed and waterproof. In this way, sealing and waterproofing are achieved at two places, and the waterproof effect is good and comprehensive. Furthermore, by placing the waterproof ring 13 and waterproof gasket 11 on the insulating housing 7 rather than on the cable 8, the waterproof ring 13 and waterproof gasket 11 are fixed in place and prevent displacement, ensuring a good seal and facilitating installation. After assembly, no additional steps are required to connect the board-side connector 200. In this embodiment, the electrical connector 6 is a circuit board.

[0061] The left side of the exterior of the insulating shell 7 has a retaining bar 14 for mounting the waterproof ring 13, and the right side of the exterior of the insulating shell 7 has a first clamping block 15 for engaging with the clamping base 12. In this embodiment, there are two retaining bars 14, one on each side of the waterproof ring 13, to prevent displacement when connected to the board-end connector 200 and improve sealing.

[0062] The clamping base 12 includes a clamping plate 121 and an extension 122. The central portion of the clamping plate 121 has a through-hole 123 for passing the cable 8. The extensions 122 are arranged around the clamping plate 121, each with a first latching hole 124. The clamping plate 121 engages with the first latching block 15 through the first latching hole 124, pressing the waterproof gasket 11 against the outer wall of the insulating shell 7. The clamping plate 121 presses the waterproof gasket 11 against the right end wall of the insulating shell 7, securing it while ensuring a tight seal. The first latching hole 124 and the first latching block 15 facilitate installation of the clamping base 12.

The left end of the connecting portion 171 is provided with a flange 173 that cooperates with the first locking hook 162. The front and rear side walls of the insulating shell 7 are provided with a hinge shaft 18. The middle part of the locking arm 172 is installed on the hinge shaft 18. The left end of the locking arm 172 is provided with a second locking hook 174. The locking arm 172 rotates along the hinge shaft 18 to make the flange 173 cooperate with the first locking hook 162. At the same time, the second locking hook 174 is locked to the board end connector 200 connected to it. Stepped slides 163 are provided at the front and rear ends of the locking plate 16. A sliding block 19 is fixed above the insulating shell 7, and a sliding groove 20 is provided below the sliding block 19. The stepped slide 163 is inserted into the sliding groove 20.

The first locking hook 162 is locked to the locking plate 16 by rotating the locking member 17. The second locking hook is connected to the board-end connector 200 connected to it, providing the necessary force to connect the wire-end connector and the board-end connector 200, making the electrical connection point between the two more reliable and not easy to loosen in a vibrating environment, and having good stability.

[0064] The first inner film 21, the second inner film 22, the first outer film 23, the wire clamp (not shown) and the second outer film 24 are included. The first inner film 21 covers at least the connection between the electrical connector 6 and the cable 8. The first outer film 23 covers the first inner film 21 to ensure the effective electrical connection between the electrical connector 6 and the cable 8 and to provide insulation.
