Description

Technical Field

[0001] The present application relates to the technical field of connection devices, and in particular to a connector. Background Art

[0002] Connectors are devices used to achieve electrical connections between different devices. They improve the efficiency of electrical connections between devices and are currently widely used in automotive, communications, consumer electronics, data processing, industrial machinery, and other fields.

[0003] Connectors can function as receptacles, securing them to devices, panels, or circuit boards. They can also function as plugs, connecting to one end of a cable. Two connectors typically engage with a locking mechanism, maintaining a fixed relative position and achieving a stable electrical connection.

[0004] The inside of the connector may contain exposed live metal conductors. When liquid penetrates into the connector through the docking port, discharge may occur between the two metal conductors with a large potential difference, which can easily cause electrical circuit failure. Because the insulating parts and shell covering the terminals are generally made of hard materials, gaps are likely to appear between the two. To prevent liquid from entering the interior of the connector, traditional technology generally pours liquid sealing material onto the outside of the connector after the connector is assembled. Due to its fluidity, the liquid sealing material enters the surface gap between the insulating part and the shell. After the sealing material cools and solidifies, it can limit the entry of liquid into the connector to a certain extent. However, performing additional sealing treatment after the connector is assembled will make the connector production process more complicated. At the same time, the filled sealing material may fall off after cooling and solidifying, making it difficult to ensure sealing. Utility Model Content

[0005] Based on this, the present invention provides a connector that can solve or at least alleviate the above technical problems.

[0006] The utility model provides a connector, comprising:

[0007] The shell has a front end and a rear end; the shell also has an inner cavity; the inner cavity is connected between the front end and the rear end;

[0008] a first insulator, positioned and accommodated in the inner cavity;

[0009] a second insulator positioned and accommodated in the inner cavity; the second insulator is disposed relative to the first insulator and closer to the rear end of the shell;

[0010] a plurality of contact terminals, wherein the contact terminals are inserted into the first insulator and the second insulator; and

[0011] The sealing member is held between the first insulator and the second insulator; the outer peripheral edge of the sealing member is circumferentially abutted against the inner peripheral surface of the inner cavity; the sealing member also forms an interference fit with the outer peripheral surface of the contact terminal.

[0012] In the connector, the contact terminals are conductive, and the connector transmits signals or currents through the contact terminals. Because the first and second insulators are positioned and accommodated within the inner cavity, when the contact terminals are fixedly inserted into the first and second insulators, the contact terminals maintain a stable position within the inner cavity. During connector assembly, a seal is assembled between the first and second insulators. Because the first and second insulators respectively press against the two side surfaces of the seal, the seal maintains a flat state. The outer edge of the seal exerts pressure on the inner circumference of the inner cavity, evenly fitting the seal and effectively eliminating any gaps between the seal and the inner circumference of the inner cavity. Furthermore, the seal forms an interference fit with the outer circumference of the contact terminals, allowing the seal to adhere closely to the outer circumference of each contact terminal, eliminating any gaps between the seal and the contact terminals. The seal acts as a sealant within the inner cavity, preventing liquid at the front end from flowing through the inner cavity into the connector interior. Since the seal is installed into the housing during connector assembly, the need for additional sealing processing after connector assembly is avoided, thus reducing the complexity of the connector production process. At the same time, due to the support of the first insulator and the second insulator, the sealing member in a flat state has a stable fitting effect on the inner circumference of the inner cavity and the outer circumference of the contact terminal, thereby providing a relatively stable sealing effect.

[0015] In one embodiment, one of the first insulator and the second insulator is provided with a positioning post, and the other is provided with a positioning groove; the positioning post passes through the sealing member, and the positioning post is inserted into the positioning groove.

[0016] In one embodiment, the sealing member is provided with a through hole; the contact terminal is inserted into the through hole; the sealing member is provided with a fifth annular flange portion; the fifth annular flange portion is provided to protrude toward the inner periphery of the through hole relative to the circumferential boundary surface of the through hole; the fifth annular flange portion is supported against the outer periphery of the contact terminal.

[0018] In one embodiment, a plurality of the sixth annular protruding edge portions are spaced apart along the thickness direction of the sealing member at the outer peripheral edge.

[0019] In one embodiment, the cross-sectional width of the sixth annular flange portion decreases from the outer peripheral edge of the sealing element to the inner peripheral surface of the inner cavity.

[0034] The technical solutions provided by the embodiments of the present application are described below with reference to the accompanying drawings.

[0035] Combine Figures 1 to 8 As shown, the present application provides a connector 100. In some embodiments, the connector 100 is used as a device for achieving electrical connection between different devices. In other embodiments, the connector 100 is used in the same device to achieve electrical connection between different electrical modules. In some embodiments, the connector 100 can be fixed to a device, panel, or circuit board. In other embodiments, the connector 100 is installed at one end of an electrical cable.

[0036] In some embodiments, combined Figure 1 and Figure 2 As shown, the connector 100 includes: a shell 20, a first insulator 30, a second insulator 40, a plurality of contact terminals 50 and a seal 60. The shell 20 is provided with a front end 21 and a rear end 22. The shell 20 is also provided with an inner cavity 23. The inner cavity 23 is connected between the front end 21 and the rear end 22. The first insulator 30 is positioned and accommodated in the inner cavity 23. The second insulator 40 is positioned and accommodated in the inner cavity 23. The second insulator 40 is arranged closer to the rear end 22 of the shell 20 relative to the first insulator 30. The contact terminal 50 is inserted into the first insulator 30 and the second insulator 40. The seal 60 is supported between the first insulator 30 and the second insulator 40. The outer peripheral edge of the seal 60 is circumferentially in contact with the inner peripheral surface of the inner cavity 23. The seal 60 also forms an interference fit with the outer peripheral surface of the contact terminal 50.

[0037] Specifically, the contact terminals 50 are conductive, and the connector 100 transmits signals or currents through the contact terminals 50. Because the first insulator 30 and the second insulator 40 are positioned and accommodated within the inner cavity 23, when the contact terminals 50 are fixedly inserted into the first insulator 30 and the second insulator 40, the contact terminals 50 maintain a stable position within the inner cavity 23. During assembly of the connector 100, the seal 60 is assembled between the first insulator 30 and the second insulator 40. Because the two side surfaces are respectively supported by the first insulator 30 and the second insulator 40, the seal 60 maintains a flat state. The outer edge of the seal 60 exerts pressure on the inner circumference of the inner cavity 23, evenly contacting the inner circumference, effectively eliminating any gaps between the seal 60 and the inner circumference of the inner cavity 23. Furthermore, the seal 60 forms an interference fit with the outer circumference of the contact terminals 50, allowing the seal 60 to closely adhere to the outer circumference of each contact terminal 50, eliminating any gaps between the seal 60 and the contact terminals 50. The seal 60 provides a seal and separation within the inner cavity 23, preventing liquid from the front end 21 from flowing through the inner cavity 23 into the interior of the connector 100. Because the seal 60 is installed in the housing 20 during the assembly of the connector 100, the need for additional sealing processing after the connector 100 is assembled is avoided, thus reducing the complexity of the production process of the connector 100. Furthermore, due to the support provided by the first insulator 30 and the second insulator 40, the seal 60, in its flattened state, maintains a stable contact with the inner circumference of the inner cavity 23 and the outer circumference of the contact terminal 50, thereby providing a relatively stable sealing effect.

[0038] In some embodiments, combined Figure 1 and Figure 2 As shown, the direction from the rear end 22 of the housing 20 to the front end 21 is the same as the insertion direction of the connector 100. In some embodiments, the Figure 7 and Figure 8 As shown, when the connector 100 is used as a plug, the connector 100 is inserted into the socket along the insertion direction. Figure 1 As shown, the connector 100 can also function as a socket.

[0039] In some embodiments, the seal 60 is flexible or elastic. In some embodiments, the seal 60 is a flexible sealing pad.

[0040] In some embodiments, combined Figure 3 and Figure 6As shown, the seal 60 has a first surface 601 facing the first insulator 30. The seal 60 has a first annular flange portion 61 that protrudes relative to the first surface 601. The first annular flange portion 61 is arranged around the outer circumference of the seal 60 and abuts against the first insulator 30. Specifically, in the radial cross-sectional direction, due to the small cross-sectional width of the first annular flange portion 61, the first annular flange portion 61 is relatively easily compressed and deformed when abutting against the surface of the first insulator 30. The first annular flange portion 61 can fully adhere to the surface of the first insulator 30, thereby preventing liquid from entering the opposing area between the seal 60 and the first insulator 30, thereby preventing liquid from penetrating into the interior of the connector 100 from this opposing area.

[0041] In some embodiments, combined Figure 3 and Figure 6 As shown, the seal 60 is provided with a second annular flange portion 62 that protrudes relative to the first surface 601. The second annular flange portion 62 is provided in a one-to-one correspondence with the contact terminal 50, surrounding the outer periphery of the corresponding contact terminal 50 and abutting the first insulator 30. In some embodiments, the seal 60 faces one side of the first insulator 30, and each contact terminal 50 is surrounded by a second annular flange portion 62. The second annular flange portion 62 abuts the first insulator 30. Due to the small cross-sectional width of the second annular flange portion 62, the second annular flange portion 62 relatively easily undergoes compression deformation and can fully adhere to the surface of the first insulator 30. The second annular flange portion 62 provides enhanced protection for the contact terminal 50, preventing liquid from passing through the opposing area between the seal 60 and the first insulator 30 and contacting the contact terminal 50, thereby preventing discharge from the contact terminal 50 due to contact with liquid.

[0042] In some embodiments, combined Figure 3 and Figure 6 As shown, within the range of the first surface 601 , all the second annular flange portions 62 are within the surrounding range of the first annular flange portion 61 .

[0043] In some embodiments, combined Figure 2 、 Figure 5 and Figure 6As shown, the seal 60 has a second surface 602 facing the second insulator 40. The seal 60 has a third annular flange portion 63 that protrudes relative to the second surface 602. The third annular flange portion 63 is disposed around the outer circumference of the seal 60 and abuts against the second insulator 40. Specifically, in the radial cross-sectional direction, due to the small cross-sectional width of the third annular flange portion 63, the third annular flange portion 63 is relatively easily compressed and deformed when abutting against the surface of the second insulator 40. The third annular flange portion 63 can fully adhere to the surface of the second insulator 40, thereby preventing liquid from entering the opposing area between the seal 60 and the second insulator 40, thereby preventing liquid from penetrating into the interior of the connector 100 from this opposing area.

[0044] In some embodiments, combined Figure 2 、 Figure 5 and Figure 6 As shown, the seal 60 is provided with a fourth annular flange portion 64 that protrudes relative to the second surface 602. The fourth annular flange portion 64 is provided in a one-to-one correspondence with the contact terminal 50, surrounding the outer periphery of the corresponding contact terminal 50 and abutting the second insulator 40. In some embodiments, the seal 60 faces one side of the second insulator 40, and each contact terminal 50 is surrounded by the fourth annular flange portion 64. The fourth annular flange portion 64 abuts the second insulator 40. Due to the small cross-sectional width of the fourth annular flange portion 64, the fourth annular flange portion 64 is relatively easy to compress and deform, and can fully adhere to the surface of the second insulator 40. The fourth annular flange portion 64 enhances protection for the contact terminal 50, preventing liquid from passing through the opposing area between the seal 60 and the second insulator 40 and contacting the contact terminal 50, thereby preventing discharge from the contact terminal 50 due to contact with liquid.

[0045] In some embodiments, combined Figure 5 As shown, within the range of the second surface 602 , all of the fourth annular flange portions 64 are within the surrounding range of the third annular flange portion 63 .

[0046] In some embodiments, combined Figure 5 and Figure 6 As shown, the sealing member 60 is provided with a through hole 65 , and the contact terminal 50 is passed through the through hole 65 .

[0047] In some embodiments, combined Figures 4 to 6As shown, the seal 60 is provided with a fifth annular flange portion 66. The fifth annular flange portion 66 is provided to protrude toward the inner periphery of the through-hole 65 relative to the circumferential boundary surface of the through-hole 65. The fifth annular flange portion 66 abuts against the outer periphery of the contact terminal 50. Specifically, in a cross section passing through the center of the through-hole 65, the cross-sectional width of the fifth annular flange portion 66 is less than the thickness of the seal 60. Due to the smaller cross-sectional width of the fifth annular flange portion 66, when the fifth annular flange portion 66 abuts against the outer periphery of the contact terminal 50, the fifth annular flange portion 66 is relatively easily compressed and deformed. The fifth annular flange portion 66 can fully adhere to the outer periphery of the contact terminal 50, thereby preventing liquid from entering the connector 100 through the gap between the contact terminal 50 and the seal 60.

[0048] In some embodiments, combined Figure 6 As shown, several fifth annular flange portions 66 are spaced apart in the through hole 65 along the thickness direction of the seal 60, so that the outer periphery of the same contact terminal 50 is simultaneously abutted against several fifth annular flange portions 66, thereby further eliminating the gap between the contact terminal 50 and the seal 60 and improving the sealing effect.

[0049] In some embodiments, combined Figure 2 and Figure 6 As shown, the seal 60 is formed with a sixth annular flange portion 67 on its outer peripheral edge. The sixth annular flange portion 67 is arranged around the outer periphery of the seal 60. The width of the sixth annular flange portion 67 is less than the thickness of the middle portion of the seal 60. The sixth annular flange portion 67 abuts the inner peripheral surface of the inner cavity 23. Specifically, in a direction perpendicular to the cross-section of the seal 60, because the cross-sectional width of the sixth annular flange portion 67 is less than the thickness of the middle portion of the seal 60, when the sixth annular flange portion 67 abuts the inner peripheral surface of the inner cavity 23, the sixth annular flange portion 67 relatively easily undergoes compression deformation, and the sixth annular flange portion 67 can fully adhere to the inner peripheral surface of the inner cavity 23. Therefore, the sixth annular flange portion 67 can prevent liquid from passing through the opposing area between the seal 60 and the inner peripheral surface of the inner cavity 23, thereby preventing liquid from penetrating into the interior of the connector 100 from this opposing area.

[0050] In some embodiments, combined Figure 6 As shown, several sixth annular flange portions 67 are spaced apart along the thickness direction of the seal 60 at the outer peripheral edge, so that several sixth annular flange portions 67 are in contact between the seal 60 and the inner peripheral surface of the inner cavity 23, thereby further eliminating the gap between the inner peripheral surface of the inner cavity 23 and the seal 60 and improving the sealing effect.

[0051] In some embodiments, combined Figure 6As shown, the cross-sectional width of the sixth annular flange portion 67 decreases gradually from the outer peripheral edge of the seal 60 toward the inner circumference of the inner cavity 23. Specifically, the cross-sectional width of the sixth annular flange portion 67 is parallel to the thickness of the seal 60. Along the relative direction between the outer peripheral edge of the seal 60 and the inner circumference of the inner cavity 23, the sixth annular flange portion 67 has different widths at different positions. Furthermore, at the outermost edge of the sixth annular flange portion 67, the smaller width allows it to better conform to the shape of the inner circumference of the inner cavity 23, ensuring a more consistent fit between the sixth annular flange portion 67 and the inner circumference of the inner cavity 23.

[0052] In some embodiments, the cross-sectional shape of the first annular flange portion 61, the second annular flange portion 62, the third annular flange portion 63, the fourth annular flange portion 64, the fifth annular flange portion 66, and the sixth annular flange portion 67 is selected from one or more of a triangle, a semicircle, and a semi-ellipse. The first annular flange portion 61, the second annular flange portion 62, the third annular flange portion 63, the fourth annular flange portion 64, the fifth annular flange portion 66, and the sixth annular flange portion 67 may also adopt other cross-sectional shapes.

[0053] In some embodiments, combined Figure 2 and Figure 3 As shown, one of the first insulator 30 and the second insulator 40 is provided with a positioning post 31, and the other is provided with a positioning groove 41. The positioning post 31 is passed through the seal 60, and the positioning post 31 is inserted into the positioning groove 41. Specifically, by passing the positioning post 31 through the seal 60 and being inserted into the positioning groove 41, the relative directions between the first insulator 30, the second insulator 40 and the seal 60 can be defined. In some embodiments, the positioning post 31 is provided on the side of the first insulator 30 facing the second insulator 40. The positioning groove 41 is provided on the side of the second insulator 40 facing the first insulator 30. Specifically, by passing the positioning post 31 through the seal 60, in addition to limiting the position of the seal 60, the flatness of the seal 60 can also be improved, ensuring the fit of the inner circumference of the inner cavity 23 of the seal 60.

[0054] In some embodiments, combined Figure 2 and Figure 3 As shown, the seal 60 is provided with a positioning hole 68, and the positioning post 31 is passed through the positioning hole 68. In some embodiments, there are multiple positioning posts 31 and positioning holes 68, and the positioning posts 31 and positioning holes 68 are distributed at different positions between the first insulator 30 and the second insulator 40, thereby ensuring the angular accuracy between the first insulator 30 and the second insulator 40.

[0055] In some embodiments, combined Figure 3 and Figure 6As shown, within the scope of the first surface 601, the opening of the positioning hole 68 is within the surrounding range of the first annular flange portion 61, and the opening is outside the surrounding range of the second annular flange portion 62. Therefore, the liquid outside the first annular flange portion 61 and the liquid in the second annular flange portion 62 cannot flow into the positioning hole 68, thereby preventing the liquid from penetrating into the connector 100 through the positioning hole 68. In some embodiments, within the scope of the second surface 602, the opening of the positioning hole 68 is within the surrounding range of the third annular flange portion 63 and the opening is outside the surrounding range of the fourth annular flange portion 64. Therefore, the liquid outside the third annular flange portion 63 and the liquid in the fourth annular flange portion 64 cannot flow into the positioning hole 68, thereby preventing the liquid from penetrating into the connector 100 through the positioning hole 68.

[0056] In some embodiments, combined Figure 2 and Figure 8 As shown, one of the first insulator 30 and the second insulator 40 is restrained by the housing 20, while the other is positioned and connected to the housing 20. Specifically, one of the first insulator 30 and the second insulator 40 is first installed into the housing 20 and restrained in its entry direction, and then the other is positioned and connected to the housing 20. The later-installed insulator retains the earlier-installed insulator within the housing 20 through abutment between the first and second insulators 30, 40, thereby simplifying installation of the connector 100.

[0057] In some embodiments, combined Figure 2 and Figure 8 As shown, the housing 20 is provided with a first limiting stepped surface 24 .

[0058] The first limiting step surface 24 is oriented in the same direction as the direction from the first insulator 30 to the second insulator 40 .

[0059] The first limiting step surface 24 abuts against the first insulator 30. The second insulator 40 is positioned and connected to the housing 20. In some embodiments, the second insulator 40 is snap-fitted to the housing 20. In some embodiments, the second insulator 40 is snap-fitted to the slot 25 on the inner circumferential surface of the inner cavity 23 by a snap-fit ​​block 43, thereby limiting the second insulator 40 from exiting the housing 20 and stably limiting the seal 60 between the first insulator 30 and the second insulator 40. In other embodiments, the second insulator 40 can also be positioned and connected to the housing 20 by threaded engagement and abutment. In other embodiments, the second insulator 40 can also be positioned and connected to the housing 20 by fasteners or with the support of other components.

[0060] In some other embodiments, the housing 20 is provided with a second limiting step surface. The second limiting step surface is oriented in the same direction as the direction from the second insulator 40 to the first insulator 30. The second limiting step surface abuts the second insulator 40. The first insulator 30 is positioned and connected to the housing 20.

[0061] In some embodiments, combined Figure 4 As shown, the first insulator 30 is provided with a third limiting step surface 32, the third limiting step surface 32 faces the second insulator 40, and the third limiting step surface 32 is arranged along the circumference of the contact terminal 50, and the third limiting step surface 32 abuts against the contact terminal 50. Figure 3 As shown, the second insulator 40 is provided with a fourth limiting stepped surface 42. The fourth limiting stepped surface 42 faces the second insulator 40 and is arranged along the circumference of the contact terminal 50. The fourth limiting stepped surface 42 abuts against the contact terminal 50. Specifically, after the connector 100 is assembled, the first insulator 30 and the second insulator 40 are in a stable relative position. When the first insulator 30 abuts the contact terminal 50 via the third limiting stepped surface 32, the second insulator 40 abuts the contact terminal 50 via the fourth limiting stepped surface 42, thereby stably confining the contact terminal 50 within the housing 20.

[0062] In some embodiments, combined Figure 2 As shown, the portion of the contact terminal 50 accommodated in the second insulator 40 is provided with a circumferential stepped surface 51, which abuts against the fourth limiting stepped surface 42. The end of the contact terminal 50 away from the rear end 22 of the housing 20 abuts against the third limiting stepped surface 32.

[0063] In some embodiments, the contact terminals 50 are made of metal so as to be able to transmit current or signals.

[0064] In some embodiments, combined Figure 7 and Figure 8 As shown, the connector 100 further includes a housing 70 . The shell 20 is accommodated in the housing 70 , so that the housing 20 can be protected by the housing 70 .

[0065] The above embodiments are merely descriptions of the preferred embodiments of the present application and do not limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements made to the technical solutions of the present application by ordinary engineering and technical personnel in this field should fall within the scope of protection determined by the claims of the present application.
