[0060] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0061] like Figures 1 to 6 As shown, the electric connector of the utility model includes a connector body 1, and the connector body 1 includes a connector shell 101, a first sealing member 102 and a supporting member. The first sealing member 102 is arranged between the connector shell 101 and the supporting member, and the supporting member is connected to the connector shell 101 to limit the first sealing member 102 through the supporting member and the connector shell 101, so that the connector body 1 constitutes an integral structure that can be assembled separately, so that the assembly of the electric connector is relatively simple and convenient, which is conducive to improving the assembly efficiency. The connector shell 101, the first sealing member 102 and the supporting member jointly form a channel suitable for the cable 201 to pass through. After the connector body 1 is assembled, the cable 201 and other parts can be further installed. The first sealing member 102 can seal the surrounding of the cable 201 to play a waterproof and dustproof role.

[0062] As a preferred embodiment, Figure 5 and Figure 8 As shown, the support member of this embodiment includes a shielding shell 103, and the shielding shell 103 is provided with a first through hole 401 for forming a channel. The shielding shell 103 is connected to the connector housing 101 so that the first sealing member 102 can be installed on the connector housing 101 through the shielding shell 103, so that the connector body 1 constitutes an integral structure. The shielding shell 103 is used to realize the grounding of the cable 201 to enhance the anti-interference ability of the cable 201 and realize the shielding function of the electrical connector. The shielding shell 103 in this embodiment is used to connect the metal shell and the cable 201. In some specific embodiments, the metal shell can be the metal shell of the object connected to the electrical connector, or it can be an additional metal shell of the electrical connector, as long as the cable assembly 2 can be grounded to achieve shielding.

[0063] As a preferred embodiment, Figure 5 As shown, the electrical connector of this embodiment also includes a support sleeve 104, which is arranged between the first seal 102 and the shielding shell 103 to axially support the first seal 102 and the shielding shell 103. The support sleeve 104 is provided with a second through hole 402 for forming a channel. In the subsequent installation process of the cable 201, when the cable 201 passes through the channel, the support sleeve 104 can limit the first seal 102 to avoid the first seal 102 moving forward and backward to cause the sealing function to fail, thereby improving the yield rate.

[0064] As a preferred embodiment, Fig.10 and Fig.11As shown, the connector housing 101 is formed with an annular protrusion 11, and the first sealing member 102 and the shielding shell 103 are arranged in the annular protrusion 11, so that during installation, the first sealing member 102 and the supporting sleeve 104 can be first arranged in the annular protrusion 11, and the inner side wall of the annular protrusion 11 cooperates with the side surface of the first sealing member 102 and the side surface of the supporting sleeve 103 to avoid the first sealing member 102 and the supporting sleeve 104 from moving radially thereof when the shielding shell 103 is subsequently installed, thereby further increasing the convenience of assembly.

[0065] As a specific implementation method, Figure 4 As shown, the electrical connector of this embodiment also includes a cable assembly 2 and a connector. The connector is used to install the cable assembly 2 on the connector body 1. The cable assembly 2 can pass through the channel. Since the connector body 1 adopts an integral design, the first sealing member 102 and the shielding shell 103 can be assembled with the connector housing 101 to form the connector body first, and then the cable assembly 2 passes through the channel. Finally, the cable assembly 2 is installed on the connector body through the connector. The cable assembly 2 of this embodiment is installed later, so that the connector body 1 and the cable assembly 2 can be assembled independently. Compared with the prior art, the cable assembly 2 will be affected by other components of the connector during the assembly process. The cable assembly 2 of the utility model is assembled independently to avoid interfering with the crimping work of the cable assembly 2, which greatly facilitates the assembly of the cable assembly 2. In addition, the independent assembly of the connector body 1 and the cable assembly 2 makes the production process more flexible. Parallel workstations can be set to process the connector body 1 and the cable assembly 2 at the same time, and finally complete the final assembly of the electrical connector, thereby reducing the total process time of the assembly and improving production efficiency.

[0066] As a preferred embodiment, Figures 5 to 7 As shown, the cable assembly 2 of this embodiment includes a cable 201, a shielding ring 202 and a terminal 203. The shielding ring 202 is sleeved on the cable 201 and crimped with the cable 201. The terminal 203 is crimped on one end of the cable 201. The connecting piece is a tail cover 3. The tail cover 3 is provided with a third through hole 403 for forming a channel. After the cable 201 passes through the third through hole 403, the tail cover 3 presses the shielding ring 202 onto the shielding shell 103, thereby realizing the electrical connection between the cable 201 and the shielding shell 103. In some further preferred embodiments, the tail cover 3 is snapped with the connector housing 1. Compared with the bolts and blocks used in the prior art to limit the shielding ring, the number of parts is reduced, the assembly process is simplified, and the production efficiency is improved.

[0067] As a preferred embodiment, Figure 8 and Fig.10As shown, the first through hole 401 is formed with a circumferential conductive spring sheet 5 suitable for contacting with the shielding ring 202, the shielding ring 202 is formed with an overlapping edge 14, and the tail cover 3 is suitable for pressing the overlapping edge 14 onto the circumferential conductive spring sheet 5. The overlapping edge 14 and the circumferential conductive spring sheet 5 cooperate to ensure the stable connection between the shielding ring 202 and the shielding shell 103.

[0068] As a preferred embodiment, Figure 8 As shown, the shielding shell 103 is formed with an end face conductive spring piece 6 for contacting with the end face of the metal shell and a radial conductive spring piece 7 for contacting with the inner wall of the metal shell. In this embodiment, the upper and lower sides of the shielding shell 103 are formed with end face conductive spring pieces 6, and the left and right sides of the shielding shell 103 are formed with radial conductive spring pieces 7. The end face conductive spring piece 6 is arranged between the end face of the metal shell and the end face of the connector shell 101, and the radial conductive spring piece 7 contacts with the inner wall of the metal shell, thereby realizing the full-circle contact between the shielding shell 103 and the metal shell, the shielding effect is better, and the reliability of the shielding function is higher.

[0069] As a preferred implementation mode, Figure 8 and Fig.11 As shown, the electrical connector of this embodiment includes multiple cable assemblies 2, the number of channels corresponds to the number of cable assemblies 2, and the electrical connector of this embodiment has multiple cables 201. Compared with the prior art, each cable 201 needs to be matched with a separate sealing ring and other components. The first sealing member 102, the support sleeve 104, the shielding shell 103 and the tail cover 3 of the present application are all provided with multiple through holes, so that the first sealing member 102, the support sleeve 104, the shielding shell 103 and the tail cover 3 of the present application can correspond to multiple cables 201, reducing the number of parts and simplifying the assembly process.

[0070] In some specific embodiments, in order to adapt to a specific working environment, the wire diameters of the cables 201 of the multiple cable assemblies 2 are different, so that the apertures of the multiple channels correspond to the wire diameters of the multiple cables 201. When the cables 201 are installed in channels with mismatched apertures, the sealing function of the first seal 102 may fail. As a preferred embodiment, Fig.11 and Fig.12As shown, one of the opposite sides of the connector housing 101 and the first sealing member 102 is formed with a first anti-error rib 901, and the other is formed with a first anti-error groove 902, and the first anti-error rib 901 and the first anti-error groove 902 are arranged correspondingly to each other, and one of the opposite sides of the first sealing member 102 and the support sleeve 104 is formed with a second anti-error groove 1002, and the other is formed with a second anti-error rib 1001, and the second anti-error rib 1001 and the second anti-error groove 1002 are arranged correspondingly to each other. In this embodiment, the first anti-error rib 901 and the first anti-error groove 902 are both arranged in an arc shape to ensure the installation of the connector housing 101 and the first sealing member 102 The second anti-error rib 1001 and the second anti-error groove 1002 are respectively arranged at the center left position of the opposite side of the first seal 102 and the support sleeve 104 to ensure the consistency of the installation direction of the first seal 102 and the support sleeve 104, thereby ensuring the assembly consistency of the connector housing 101, the first seal 102 and the support sleeve 104 through the anti-error installation structure, eliminating process errors, and when the wire diameters of the cable assembly 2 of the electrical connector are different, it is beneficial to improve the assembly accuracy and reduce the risk of mismatch between the aperture of the fifth through hole 405 of the first seal 102 and the wire diameter of the cable 201, thereby improving the yield rate of the electrical connector. Figure 1 and Figure 3 As shown, in some further preferred embodiments, it also includes a mark for indicating the aperture of the cable through hole. In this embodiment, letter marks (A, B, C, D) are set at each cable through hole on the side of the connector away from the connector housing 101 and each harness through hole on the side of the connector housing 101 away from the connector to ensure that the cable assembly 2 is correctly assembled during the installation of the electrical connector, thereby improving the reliability of the sealing function of the electrical connector. It can be understood that the error-proofing structure composed of the first error-proofing rib 901, the first error-proofing groove 902, the second error-proofing rib 1001 and the second error-proofing groove 1002 is only a specific implementation of the error-proofing structure. The error-proofing structure can be set in various shapes and can also be set in various positions, such as between the first sealing member 102 and the support sleeve 104 and between the support sleeve 104 and the shielding shell 103, which will not be repeated here.

[0071] As a preferred embodiment, Fig.11 and Fig.12As shown, a card point 1201 is formed at one corner of the support sleeve 104, and a card groove 1202 corresponding to the card point 1201 is formed at one corner of the annular protrusion 11. Since the material of the first sealing member 102 of this embodiment is relatively soft, when the support sleeve 104 is incorrectly installed, the second anti-error convex rib 1001 presses the second anti-error groove 1002, causing the first sealing member 102 to deform, resulting in the support sleeve 104 being forcibly installed on the first sealing member 102, affecting the sealing reliability of the electrical connector. The card point 1201 is formed on the support sleeve 104 of this embodiment, and the card point 1201 and the card groove 1202 cooperate to further ensure that the first sealing member 102 and the support sleeve 104 are assembled consistently. When installing the support sleeve 104, the installation direction of the support sleeve 104 can be determined based on the card point 1201, so as to facilitate the correct installation of the support sleeve 104.

[0072] As a preferred implementation mode, Figure 5 and Fig.11 As shown, the electrical connector of this embodiment also includes a second seal 105 for sealing the gap between the end face of the connector housing 101 and the end face of the metal shell. The end face of the connector housing 101 and / or the end face of the metal shell is formed with a groove 8 for installing the second seal 105, so that in some specific usage scenarios, the electrical connector of this embodiment can be installed together with a box-shaped metal shell without a cover, and the electrical connector can cooperate with the box-shaped metal shell without a cover to form a accommodating cavity. The first seal 102 seals the periphery of the cable 201, and the second seal 105 seals the gap between the end face of the connector housing 101 and the end face of the metal shell. In some further preferred embodiments, the first seal 102, the support sleeve 104, the shielding shell 103, the terminal 203 and the second seal 105 are all arranged on one side of the connector housing 101, so that the first seal 102, the support sleeve 104, the shielding shell 103 and the terminal 203 can all be arranged in the accommodating cavity, the first seal 102 is used to seal around the cable 102, and the second seal 105 is used to seal the gap between the end face of the connector housing 101 and the end face of the metal shell, so that the accommodating cavity is sealed. The connector housing 101 of this embodiment is arranged on the outside, but because the connector housing 101 is an integrated structure, the structural strength is less affected by aging, and the first seal 102, the support sleeve 104, the shielding shell 103 and the terminal 203 are arranged in the sealed accommodating cavity, which is less affected by the external environment and is not easy to age, thereby improving the overall structural strength and reliability of the electrical connector and extending the service life of the electrical connector.

[0073] The present application provides a preferred electrical connector, such as Figure 5 As shown, the present application provides a preferred electrical connector, such as Figure 5As shown, the electrical connector of this embodiment includes a connector housing 101, a first seal 102, a support sleeve 104, a shielding shell 103, a second seal 105, a cable assembly 2 and a tail cover 3. The connector housing 101, the first seal 102, the support sleeve 104, the shielding shell 103 and the tail cover 3 are sequentially formed with a fourth through hole 404, a fifth through hole 405, a second through hole 402, a first through hole 401 and a third through hole 403 corresponding to each other, and the fourth through hole 404, the fifth through hole 405, the second through hole 402, the first through hole 401 and the third through hole 403 together form a passage suitable for the cable 201 to pass through. The connector housing 101 is formed with an annular protrusion 11, in which the first sealing member 102 and the supporting sleeve 104 are sequentially installed. Compared with the prior art in which each cable assembly 2 needs to be separately assembled with corresponding sealing rings, shielding rings and other components, the first sealing member 102, the supporting sleeve 104 and the shielding shell 103 in this embodiment adopt an integral design, which reduces the number of parts, facilitates assembly and improves assembly efficiency. The opposing surfaces of the connector housing 101 and the first sealing member 102 of this embodiment respectively form a first anti-error rib 901 and a first anti-error groove 902, and the opposing surfaces of the first sealing member 102 and the support sleeve 104 respectively form a second anti-error rib 1001 and a second anti-error groove 1002, a corner of the support sleeve 104 is formed with a card point 1201, and the annular protrusion 11 is formed with a card groove 1202 corresponding to the card point 1201, thereby effectively ensuring the assembly consistency of the first sealing member 102 and the support sleeve 104 and eliminating process errors. When the wire diameters of the cable 201 are different, it is beneficial to ensure the correct assembly of the cable 201 and ensure the reliability of the sealing function, and during the installation process, the direction of the first sealing member 102 and the support sleeve 104 can be judged according to the direction of the second anti-error groove 1002 and the card point 1201, which is convenient for installation and improves installation efficiency. The shielding shell 103 of this embodiment is formed with an inverted spring sheet, which can cooperate with the corresponding position of the connector housing 101 to connect the shielding shell 103 and the connector housing 101, thereby completing the assembly of the connector body 1. The connector body 1 is an integral structure, and the connector body 1 can be assembled separately through the annular protrusion 11 and the anti-error structure on the connector housing 101, the first seal 102 and the support sleeve 104, and the consistency of the assembly is ensured. After the shielding shell 103 and the connector housing 101 are connected, the shielding shell 103 can abut the support sleeve 104, and the support sleeve 104 abuts the first seal 102, ensuring that the first seal 102 fits the connector housing 101, and preventing the first seal 102 from moving forward and backward when the wiring harness 201 passes through the fifth through hole 405, thereby limiting the movement of the first seal 102 through the support sleeve 104 and the annular protrusion 11, thereby improving the reliability of the sealing function. In this embodiment, four cable assemblies 2 are provided, and the number of the fourth through hole 4014 , the fifth through hole 405 , the second through hole 402 , the first through hole 401 , and the third through hole 403 is the same as that of the cable assemblies 2 .The cable assembly 2 includes a cable 201, a shielding ring 202 and a terminal 203. The shielding ring 202 is sleeved on the cable 201 and crimped with the cable 201. An overlapping edge 14 is formed at one end of the shielding ring 202, and a terminal 203 is crimped at one end of the cable 201 near the overlapping edge 14. Since the connector body 1 and the cable assembly 2 of this embodiment can be assembled independently, parallel workstations can be set to process the connector body 1 and the cable assembly 2 at the same time, and finally assembled, which reduces the total process time, and the independent assembly of the cable assembly 2 facilitates the crimping of the shielding ring 202 and the terminal 203.

The shielding shell 103 is formed with end face conductive spring pieces 6 on the upper and lower sides, and with radial conductive spring pieces 7 on the left and right sides. The tail cover 3 is formed with a notch on the upper, lower, left and right sides, and the notch is used to extend the end face conductive spring piece 6 or the radial conductive spring piece 7. The connector shell 101 is formed with a groove 8 for arranging the second sealing member 105 on one side close to the tail cover. The groove 8 is provided with fixing ribs for fixing the second sealing member 105.

The second sealing member 105 seals the gap between the end face of the connector shell 101 and the end face of the metal shell. The first sealing member 102 seals around the cable 201 to achieve the sealing of the hollow cavity. The shielding shell 103, the support sleeve 104 and other components are arranged in the sealed hollow cavity, so as to avoid the shielding shell 103, the support sleeve 104 and other components from being affected by the external environment and aging, thereby improving the service life of the electrical connector. The end face conductive spring piece 6 is arranged between the end face of the connector housing 101 and the end face of the box-shaped metal shell, and the inner wall surface of the box-shaped metal shell abuts against the radial conductive spring piece 7, so that the cable 201 is grounded to realize the shielding function of the electrical connector, and the shielding shell 103 and the box-shaped metal shell are in contact throughout the entire circumference, so that the electrical connector has a better shielding effect.
