Description

Technical Field

[0001] The present disclosure relates to an electrical connector and a cable assembly.

Background Art

[0002] Generally, when combining a cable with an electrical connector, the user needs to fold back the braided mesh layer of the cable, which makes it easier to insert the inner sleeve of the electrical connector between the insulating layer and the braided mesh layer of the cable, and ensures electrical contact between the inner sleeve and the braided mesh layer. However, such a combination method results in low combination efficiency. Therefore, researchers in this field are working on the above problems.

Summary of the Invention

[0003] The present disclosure provides an electrical connector and a cable assembly capable of improving the combination efficiency of the cable assembly.

Means for Solving the Problems

[0004] One embodiment of the present disclosure provides an electrical connector. The electrical connector is configured to be combined with a cable. The electrical connector includes a casing and an inner pressing sleeve. The casing includes a housing portion and a pressing portion. The housing portion has an installation space, and the pressing portion is at least partially located within the installation space. The inner pressing sleeve includes an annular fastening portion and at least one elastic clamping portion connected to each other, and is located within the installation space. The annular fastening portion is slidable relative to the housing portion, whereby at least one elastic clamping portion can form an installation through-hole when at least one elastic clamping portion is not pressed by the pressing portion, and can form a clamping hole when at least one elastic clamping portion is pressed by the pressing portion. The inner diameter of the installation through-hole is larger than the inner diameter of the clamping hole.

[0005] Other embodiments of the present disclosure provide a cable assembly. The cable assembly includes an electrical connector and a cable. The electrical connector includes a casing and an inner pressing sleeve. The casing includes a housing portion and a pressing portion. The housing portion has a mounting space, and the pressing portion is at least partially located within the mounting space. The inner pressing sleeve includes an annular fastening portion and at least one elastic clamping portion connected to each other, and is slidably disposed within the mounting space. The cable is mounted within the inner pressing sleeve through the mounting space of the housing portion, and at least one elastic clamping portion is pressed by the pressing portion to form a clamping hole and clamp the cable.

[0006] According to the electrical connector and the cable assembly as described in the above embodiments, the annular fastening portion of the inner pressing sleeve is slidable relative to the housing portion of the casing. Thus, the elastic clamping portion can form a mounting through-hole when not pressed by the pressing portion of the casing, and can form a clamping hole when pressed by the pressing portion of the casing. The inner diameter of the mounting through-hole is larger than the inner diameter of the clamping hole. With this configuration, during the process of inserting the cable through the mounting space of the housing portion into the inner pressing sleeve, the elastic clamping portion of the inner pressing sleeve is pressed by the pressing portion of the casing, and the braided mesh layer of the cable can be firmly clamped. As a result, it is not necessary to fold back the braided mesh layer of the cable, and the elastic clamping portion of the inner pressing sleeve is pressed by the pressing portion of the casing to firmly clamp the braided mesh layer of the cable, ensuring electrical contact between the inner pressing sleeve and the braided mesh layer of the cable. Therefore, the step of folding back the braided mesh layer of the cable when combining the cable with the electrical connector is omitted, and the combination efficiency is improved.

[0008] In the following detailed description, in order to fully understand the disclosed embodiments, a number of specific details are shown and described. However, it is obvious that one or more embodiments can be implemented without these specific details. In other examples, well-known structures and devices are schematically shown in order to simplify the drawings.

[0009] Also, the terms used in the present disclosure, such as technical terms and scientific terms, have their respective specific meanings and are understood by those skilled in the art, unless otherwise specifically defined in the present disclosure. That is, the terms used in the following paragraphs should be interpreted in the generally used meaning in the relevant field, except when they have a specific meaning in the present disclosure, and should not be overly explained.

[0010] Refer to FIGS. 1 to 3. FIG. 1 is a perspective view of the electrical connector according to the first embodiment of the present disclosure, FIG. 2 is an exploded view of the electrical connector of FIG. 1, and FIG. 3 is a perspective view of the inner pressing sleeve of FIG. 2.

[0011] In the present embodiment, the electrical connector 10a includes a casing 100a and an inner pressing sleeve 200a.

[0012] Next, refer to FIGS. 2 and 4. FIG. 4 is a cross-sectional view of the electrical connector of FIG. 1. The casing 100a includes a housing portion 110a and a pressing portion 120a. The housing portion 110a has an attachment space 111a, and the pressing portion 120a is at least partially located within the attachment space 111a. For example, the pressing portion 120a is integrally formed with the housing portion 110a and extends from the attachment space 111a of the housing portion 110a to the outside of the housing portion 110a. The casing 100a may further include a coupling portion 130a, and the electrical connector 10a may further include a positioning component 300a. The coupling portion 130a is rotatably disposed on a part of the pressing portion 120a located outside the housing portion 110a via the positioning component 300a. The coupling portion 130a has an internal thread structure and is combined with, for example, a connector (not shown) of an electronic device.

[0013] Note that the positioning component 300a is an optional component and may be omitted in other embodiments.

[0014] As shown in FIGS. 2 to 4, the inner pressing sleeve 200a is slidably disposed within the attachment space 111a and includes an annular fastening portion 210a and a plurality of elastic clamping portions 220a connected to the annular fastening portion 210a. The elastic clamping portions 220a extend from the annular fastening portion 210a in the same direction and are spaced apart from each other in the circumferential direction of the annular fastening portion 210a. The thickness of the elastic clamping portion 220a gradually increases in a direction away from the annular fastening portion 210a. In other embodiments, the thickness of the elastic clamping portion 220a may gradually decrease in a direction away from the annular fastening portion 210a or remain uniform.

[0015] In this embodiment, the electrical connector 10a may further include a guide component 500a. The guide component 500a is made of an electrical insulating material such as plastic, for example. The annular fastening portion 210a of the inner pressing sleeve 200a may have a mounting hole 211a, and the guide component 500a is movably and removably disposed within the mounting hole 211a. The guide component 500a is configured to guide the combination of the cable 20 (see FIG. 5).

[0016] Further, the electrical connector 10a may further include an annular elastic component 700a, and the casing 100a may further include a fastening cover portion 140a. The annular elastic component 700a is attached to one end of the housing portion 110a via the fastening cover portion 140a, and the annular elastic component 700a is rotatable with respect to the housing portion 110a and the fastening cover portion 140a. The annular elastic component 700a has a plurality of elastic arms 710a for stably fixing the cable 20. Note that the annular elastic component 700a and the fastening cover portion 140a are optional components and may be omitted in other embodiments.

[0017] Next, refer to FIGS. 4 and 5. FIG. 5 is a cross-sectional view of the electrical connector of FIG. 4 combined with a cable. The electrical connector 10a is combined with the cable 20, thereby being configured to form a cable assembly 1a together with the cable 20. The cable 20 includes, from the inside to the outside, a conductive core 21, an insulating layer 22, a braided mesh layer 23 (functioning as a shielding layer), and an outer layer 24. At one end of the cable 20, the conductive core 21, the insulating layer 22, and the braided mesh layer 23 may be exposed from the outer layer 24.

[0018] Hereinafter, the procedure for combining the cable 20 with the electrical connector 10a will be described. First, as shown in FIG. 4, when the cable 20 has not yet been inserted into the electrical connector 10a, the inner pressing sleeve 200a is positioned at the non-pressing position, and as a result, the elastic clamping portion 220a of the inner pressing sleeve 200a is not pressed by the pressing portion 120a of the casing 100a. Thereby, an attachment through-hole H1a is formed on the side of the elastic clamping portion 220a that is farther from the annular fastening portion 210a. The inner diameter D1a of the attachment through-hole H1a is equal to or larger than the outer diameter D of the braided mesh layer 23 of the cable 20.

[0019] Next, as shown in FIG. 5, after the cable 20 is inserted into the mounting space 111a of the housing portion 110a through the through hole of the fastening cover portion 140a of the casing 100a, the conductive core 21 exposed from the outer layer 24 of the cable 20 is inserted into the guide component 500a. Then, the cable 20, the guide component 500a, and the inner pressing sleeve 200a move together. Next, the elastic clamping portion 220a of the moving inner pressing sleeve 200a contacts the pressing portion 120a of the casing 100a and temporarily stops. At this point, if the cable 20 is continuously pushed in, the cable 20 and the guide component 500a move relative to the inner pressing sleeve 200a until the cable 20 passes through the mounting through hole H1a and contacts the annular fastening portion 210a of the inner pressing sleeve 200a. Then, by further pushing in the cable 20, the inner pressing sleeve 200a moves, and the elastic clamping portion 220a of the inner pressing sleeve 200a is pressed by the pressing portion 120a of the casing 100a, and the clamping hole H2a is formed. In this case, the inner diameter D1a of the mounting through hole H1a is larger than the inner diameter D2a of the clamping hole H2a. As a result, the elastic clamping portion 220a of the inner pressing sleeve 200a firmly clamps the braided mesh layer 23 of the cable 20.

[0020] In this embodiment, the annular fastening portion 210a of the inner pressing sleeve 200a is slidable relative to the housing portion 110a of the casing 100a. As a result, the elastic clamping portion 220a forms the mounting through-hole H1a when not pressed by the pressing portion 120a of the casing 100a, and can form the clamping hole H2a when pressed by the pressing portion 120a. The inner diameter D1a of the mounting through-hole H1a is larger than the inner diameter D2a of the clamping hole H2a. With this configuration, in the process of inserting the cable 20 into the inner pressing sleeve 200a through the mounting space 111a of the housing portion 110a, the elastic clamping portion 220a of the inner pressing sleeve 200a is pressed by the pressing portion 120a of the casing 100a, and the braided mesh layer 23 of the cable 20 can be firmly clamped. As a result, it is not necessary to fold back the braided mesh layer 23 of the cable 20, and the elastic clamping portion 220a of the inner pressing sleeve 200a is pressed by the pressing portion 120a of the casing 100a to firmly clamp the braided mesh layer 23 of the cable 20, ensuring electrical contact between the inner pressing sleeve 200a and the braided mesh layer 23 of the cable 20. Therefore, when combining the cable 20 with the electrical connector 10a, the step of folding back the braided mesh layer 23 of the cable 20 is omitted, and the combination efficiency is improved.

[0021] In this embodiment, when it is necessary to combine the cable assembly 1a with the connector of an electronic device, in order to enable the conductive core 21 of the cable 20 to be in electrical contact with the terminal of the connector of the electronic device, it is necessary to remove the guide component 500a of the electrical connector 10a from the inner pressing sleeve 200a. Note that the guide component 500a is an optional component and may be omitted in other actual application examples.

[0022] Next, refer to FIGS. 6 and 7. FIG. 6 is an exploded view of an electrical connector according to a second embodiment of the present disclosure, and FIG. 7 is a perspective view of the inner pressing sleeve of FIG. 6.

[0023] In this embodiment, the electrical connector 10b includes a casing 100b and an inner pressing sleeve 200b.

[0024] Next, refer to FIGS. 6 and 8. FIG. 8 is a cross-sectional view of the electrical connector of FIG. 6. The casing 100b includes a housing portion 110b and a pressing portion 120b. The housing portion 110b has a mounting space 111b, and the pressing portion 120b is at least partially located within the mounting space 111b. For example, the pressing portion 120b is integrally formed with the housing portion 110b and extends from the mounting space 111b of the housing portion 110b to the outside of the housing portion 110b. The casing 100b may further include a coupling portion 130b, and the electrical connector 10b may further include a positioning component 300b. The coupling portion 130b is rotatably disposed on a part of the pressing portion 120b located outside the housing portion 110b via the positioning component 300b. The coupling portion 130b has an internal thread structure and is, for example, combined with a connector of an electronic device (not shown).

[0025] Note that the positioning component 300b is an optional component and may be omitted in other embodiments.

[0026] As shown in FIGS. 6 to 8, the inner pressing sleeve 200b is slidably disposed within the mounting space 111b and includes an annular fastening portion 210b and a plurality of elastic clamping portions 220b connected to the annular fastening portion 210b. The elastic clamping portions 220b extend from the annular fastening portion 210b in the same direction and are spaced apart from each other in the circumferential direction of the annular fastening portion 210b. Each of the elastic clamping portions 220b includes a peripheral portion 221b and an inner arm portion 222b. In one elastic clamping portion 220b, two ends of the peripheral portion 221b are connected to the annular fastening portion 210b, the peripheral portion 221b and the annular fastening portion 210b together form an opening O, and the inner arm portion 222b is connected to the peripheral portion 221b and is located within the opening O. In other embodiments, the inner arm portion 222b may be directly connected to the annular fastening portion 210b.

[0027] In this embodiment, the electrical connector 10b may further include a guide component 500b. The guide component 500b is made of an electrical insulating material such as plastic. The annular fastening portion 210b of the inner pressing sleeve 200b may have a mounting hole 211b, and the guide component 500b is movably and removably disposed within the mounting hole 211b. The guide component 500b is configured to guide the combination of the cable 20 (see FIG. 10).

[0028] In addition, the electrical connector 10b may further include an annular elastic component 700b, and the casing 100b may further include a fastening cover portion 140b. The annular elastic component 700b is mounted on one end of the housing portion 110b via the fastening cover portion 140b, and the annular elastic component 700b is rotatable with respect to the housing portion 110b and the fastening cover portion 140b. The annular elastic component 700b has a plurality of elastic arms 710b for stably fixing the cable 20. Note that the annular elastic component 700b and the fastening cover portion 140b are optional components and may be omitted in other embodiments.

[0029] Next, refer to FIGS. 8 to 11. FIG. 9 is a cross-sectional view of the electrical connector along line 9-9 of FIG. 8, FIG. 10 is a cross-sectional view of the electrical connector of FIG. 8 combined with a cable, and FIG. 11 is a cross-sectional view of the electrical connector along line 11-11 of FIG. 10.

[0030] The electrical connector 10b is combined with the cable 20, thereby being configured to form a cable assembly 1b together with the cable 20. The cable 20 includes a conductive core 21, an insulating layer 22, a braided mesh layer 23 (functioning as a shielding layer), and an outer layer 24 from the inside to the outside. At one end of the cable 20, the conductive core 21, the insulating layer 22, and the braided mesh layer 23 may be exposed from the outer layer 24.

[0031] The following describes the procedure for combining the cable 20 with the electrical connector 10b. First, as shown in FIGS. 8 and 9, when the cable 20 has not yet been inserted into the electrical connector 10b, the inner pressing sleeve 200b is in the non-pressed position. As a result, the elastic clamping portion 220b of the inner pressing sleeve 200b is not pressed by the pressing portion 120b of the casing 100b. Thereby, an attachment through-hole H1b is formed on the side of the elastic clamping portion 220b that is farther from the annular fastening portion 210b. The inner diameter D1b (referring to the maximum inner diameter) of the attachment through-hole H1b is equal to or greater than the outer diameter D of the braided mesh layer 23 of the cable 20.

[0032] Next, as shown in FIGS. 10 and 11, after the cable 20 is inserted into the attachment space 111b of the housing portion 110b through the through-hole of the fastening cover portion 140b of the casing 100b, the conductive core 21 exposed from the outer layer 24 of the cable 20 is inserted into the guide component 500b. Thereafter, the cable 20, the guide component 500b, and the inner pressing sleeve 200b move together. As the inner pressing sleeve 200b moves, the elastic clamping portion 220b comes into contact with the pressing portion 120b of the casing 100b and temporarily stops. At this point, if the cable 20 is continuously pushed in, the cable 20 and the guide component 500b move relative to the inner pressing sleeve 200b until the cable 20 passes through the attachment through-hole H1b and contacts the annular fastening portion 210b of the inner pressing sleeve 200b. In this process, the inner arm portion 222b of the elastic clamping portion 220b of the inner pressing sleeve 200b is expanded outward by the braided mesh layer 23 of the cable 20. Thereafter, if the cable 20 is continuously pushed in, the inner pressing sleeve 200b moves, and the peripheral portion 221b of the elastic clamping portion 220b is pressed inward by the pressing portion 120b of the casing 100b, whereby a clamping hole H2b is formed in the inner arm portion 222b of the elastic clamping portion 220b. The inner diameter D1b of the attachment through-hole H1b is larger than the inner diameter D2b of the clamping hole H2b. In this way, the elastic clamping portion 220b of the inner pressing sleeve 200b firmly clamps the braided mesh layer 23 of the cable 20.

[0033] In this embodiment, the annular fastening portion 210b of the inner pressing sleeve 200b is slidable relative to the housing portion 110b of the casing 100b. As a result, the elastic clamping portion 220b forms the mounting through hole H1b when not pressed by the pressing portion 120b of the casing 100b, and can form the clamping hole H2b when pressed by the pressing portion 120b. The inner diameter D1b of the mounting through hole H1b is larger than the inner diameter D2b of the clamping hole H2b. With this configuration, during the process of inserting the cable 20 through the mounting space 111b of the housing portion 110b into the inner pressing sleeve 200b, the elastic clamping portion 220b of the inner pressing sleeve 200b is pressed by the pressing portion 120b of the casing 100b, and the braided mesh layer 23 of the cable 20 can be firmly clamped. As a result, it is not necessary to fold back the braided mesh layer 23 of the cable 20. The elastic clamping portion 220b of the inner pressing sleeve 200b is pressed by the pressing portion 120b of the casing 100b to firmly clamp the braided mesh layer 23 of the cable 20, ensuring electrical contact between the inner pressing sleeve 200b and the braided mesh layer 23 of the cable 20. Therefore, the step of folding back the braided mesh layer 23 of the cable 20 during the process of combining the cable 20 with the electrical connector 10b is omitted, and the combination efficiency is improved.

[0034] In this embodiment, when it is necessary to combine the cable assembly 1b with the connector of the electronic device, in order for the conductive core 21 of the cable 20 to be electrically contacted with the terminal of the connector of the electronic device, it is necessary to remove the guide component 500b of the electrical connector 10b from the inner pressing sleeve 200b. Note that the guide component 500b is an optional component and may be omitted in other actual application examples.

[0035] Next, refer to FIGS. 12 and 13. FIG. 12 is an exploded view of an electrical connector according to the third embodiment of the present disclosure, and FIG. 13 is a perspective view of the inner pressing sleeve of FIG. 12.

[0036] In this embodiment, the electrical connector 10c includes a casing 100c and an inner pressing sleeve 200c.

[0037] Next, refer to FIGS. 12 and 14. FIG. 14 is a cross-sectional view of the electrical connector of FIG. 12.

[0038] The casing 100c includes a housing portion 110c and a pressing portion 120c. The housing portion 110c has a mounting space 111c, and the pressing portion 120c is at least partially located within the mounting space 111c. For example, the pressing portion 120c is integrally formed with the housing portion 110c and extends from the mounting space 111c of the housing portion 110c to the outside of the housing portion 110c. The casing 100c may further include a coupling portion 130c, and the electrical connector 10c may further include a positioning component 300c. The coupling portion 130c is rotatably arranged on a part of the pressing portion 120c located outside the housing portion 110c via the positioning component 300c. The coupling portion 130c has an internal thread structure and is combined with, for example, a connector of an electronic device (not shown).

[0039] Note that the positioning component 300c is an optional component and may be omitted in other embodiments.

[0040] As shown in FIGS. 12 to 14, the inner pressing sleeve 200c is slidably arranged within the mounting space 111c and includes an annular fastening portion 210c and a plurality of elastic clamping portions 220c connected to the annular fastening portion 210c. The elastic clamping portions 220c extend from the annular fastening portion 210c in the same direction and are spaced apart from each other in the circumferential direction of the annular fastening portion 210c. The elastic clamping portions 220c are in a wavy shape.

[0041] In this embodiment, the electrical connector 10c may further include a guide component 500c. The guide component 500c is made of an electrical insulating material such as plastic, for example. The annular fastening portion 210c of the inner pressing sleeve 200c may have a mounting hole 211c, and the guide component 500c is disposed movably and removably within the mounting hole 211c. The guide component 500c is configured to guide the combination of the cable 20 (see FIG. 15).

[0042] Also, the electrical connector 10c may further include an annular elastic component 700c, and the casing 100c may further include a fastening cover portion 140c. The annular elastic component 700c is attached to one end of the housing portion 110c via the fastening cover portion 140c, and the annular elastic component 700c is rotatable with respect to the housing portion 110c and the fastening cover portion 140c. The annular elastic component 700c has a plurality of elastic arms 710c for stably fixing the cable 20. Note that the annular elastic component 700c and the fastening cover portion 140c are optional components and may be omitted in other embodiments.

[0043] Next, refer to FIGS. 14 and 15. FIG. 15 is a cross-sectional view of the electrical connector of FIG. 12 combined with a cable. The electrical connector 10c is combined with the cable 20, and thereby configured to form a cable assembly 1c together with the cable 20. The cable 20 includes a conductive core 21, an insulating layer 22, a braided mesh layer 23 (functioning as a shielding layer), and an outer layer 24 from the inside to the outside. At one end of the cable 20, the conductive core 21, the insulating layer 22, and the braided mesh layer 23 may be exposed from the outer layer 24.

[0044] The following describes the procedure for combining the cable 20 with the electrical connector 10c. First, as shown in FIG. 14, when the cable 20 has not yet been inserted into the electrical connector 10c, the inner pressing sleeve 200c is positioned at the non-pressing position. As a result, the elastic clamping portion 220c of the inner pressing sleeve 200c is not pressed by the pressing portion 120c of the casing 100c. Thereby, the mounting through hole H1c is formed on the side farther from the annular fastening portion 210c of the elastic clamping portion 220c. The inner diameter D1c of the mounting through hole H1c is equal to or greater than the outer diameter D of the braided mesh layer 23 of the cable 20.

[0045] Next, as shown in FIG. 15, after the cable 20 is inserted into the mounting space 111c of the housing portion 110c through the through hole of the fastening cover portion 140c of the casing 100c, the conductive core 21 exposed from the outer layer 24 of the cable 20 is inserted into the guide component 500c. Thereafter, the cable 20, the guide component 500c, and the inner pressing sleeve 200c move together. Next, the elastic clamping portion 220c of the moving inner pressing sleeve 200c contacts the pressing portion 120c of the casing 100c and temporarily stops. At this point, if the cable 20 is continuously pushed in, the cable 20 and the guide component 500c move relative to the inner pressing sleeve 200c until the cable 20 passes through the mounting through hole H1c and contacts the annular fastening portion 210c of the inner pressing sleeve 200c. Thereafter, by further pushing in the cable 20, the inner pressing sleeve 200c moves, and the elastic clamping portion 220c of the inner pressing sleeve 200c is pressed by the pressing portion 120c of the casing 100c, and the clamping hole H2c is formed. In this case, the inner diameter D1c of the mounting through hole H1c is larger than the inner diameter D2c of the clamping hole H2c. As a result, the elastic clamping portion 220c of the inner pressing sleeve 200c firmly clamps the braided mesh layer 23 of the cable 20.

[0046] In this embodiment, the annular fastening portion 210c of the inner pressing sleeve 200c is slidable relative to the housing portion 110c of the casing 100c. As a result, the elastic clamping portion 220c forms the mounting through-hole H1c when not pressed by the pressing portion 120c of the casing 100c, and can form the clamping hole H2c when pressed by the pressing portion 120c. The inner diameter D1c of the mounting through-hole H1c is larger than the inner diameter D2c of the clamping hole H2c. With this configuration, in the process of inserting the cable 20 through the mounting space 111c of the housing portion 110c into the inner pressing sleeve 200c, the elastic clamping portion 220c of the inner pressing sleeve 200c is pressed by the pressing portion 120c of the casing 100c, and the braided mesh layer 23 of the cable 20 can be firmly clamped. As a result, it is not necessary to fold back the braided mesh layer 23 of the cable 20. The elastic clamping portion 220c of the inner pressing sleeve 200c is pressed by the pressing portion 120c of the casing 100c to firmly clamp the braided mesh layer 23 of the cable 20, ensuring electrical contact between the inner pressing sleeve 200c and the braided mesh layer 23 of the cable 20. Therefore, when combining the cable 20 with the electrical connector 10c, the step of folding back the braided mesh layer 23 of the cable 20 is omitted, and the combination efficiency is improved.

[0047] In this embodiment, when it is necessary to combine the cable assembly 1c with the connector of an electronic device, in order for the conductive core 21 of the cable 20 to be electrically contacted with the terminal of the connector of the electronic device, it is necessary to remove the guide component 500c of the electrical connector 10c from the inner pressing sleeve 200c. Note that the guide component 500c is an optional component and may be omitted in other actual application examples.

[0048] Next, refer to FIGS. 16 and 17. FIG. 16 is an exploded view of an electrical connector according to a fourth embodiment of the present disclosure, and FIG. 17 is a perspective view of the inner pressing sleeve of FIG. 16.

[0049] In this embodiment, the electrical connector 10d includes a casing 100d and an inner pressing sleeve 200d.

[0050] Next, refer to FIGS. 16 and 18. FIG. 18 is a cross-sectional view of the electrical connector of FIG. 16. The casing 100d includes a housing portion 110d and a pressing portion 120d. The housing portion 110d has an attachment space 111d, and the pressing portion 120d is at least partially located within the attachment space 111d. For example, the pressing portion 120d is integrally formed with the housing portion 110d and extends from the attachment space 111d of the housing portion 110d to the outside of the housing portion 110d. The casing 100d may further include a coupling portion 130d, and the electrical connector 10d may further include a positioning component 300d. The coupling portion 130d is rotatably disposed on a part of the pressing portion 120d located outside the housing portion 110d via the positioning component 300d. The coupling portion 130d has an internal thread structure and is combined with, for example, a connector of an electronic device (not shown).

[0051] Note that the positioning component 300d is an optional component and may be omitted in other embodiments.

[0052] As shown in FIGS. 16 to 18, the inner pressing sleeve 200d is slidably disposed within the attachment space 111d and includes an annular fastening portion 210d and a plurality of elastic clamping portions 220d connected to the annular fastening portion 210d. The annular fastening portion 210d includes a base 211d and an annular wall 212d. The annular wall 212d is connected to the periphery of the base 211d. The annular wall 212d has a plurality of openings 2121d, and the openings 2121d are spaced apart from each other in the circumferential direction of the annular wall 212d. The elastic clamping portions 220d are connected to the annular wall 212d and are respectively located within the openings 2121d. Depending on the actual design, each of the elastic clamping portions 220d may be connected to either side of the opening 2121d of the annular wall 212d.

[0053] In this embodiment, the electrical connector 10d may further include a guide component 500d. The guide component 500d is made of an electrically insulating material such as plastic. The base 211d of the annular fastening part 210d of the inner pressing sleeve 200d may have a mounting hole 2111d, and the guide component 500d is movably and removably arranged in the mounting hole 2111d. The guide component 500d is configured to guide the combination of the cable 20 (see FIG. 20).

[0054] In addition, the electrical connector 10d may further include an annular elastic component 700d, and the casing 100d may further include a fastening cover part 140d. The annular elastic component 700d is mounted on one end of the housing part 110d via the fastening cover part 140d, and the annular elastic component 700d is rotatable with respect to the housing part 110d and the fastening cover part 140d. The annular elastic component 700d has a plurality of elastic arms 710d for stably fixing the cable 20. Note that the annular elastic component 700d and the fastening cover part 140d are optional components and may be omitted in other embodiments.

[0055] Next, refer to FIGS. 18 to 21. FIG. 19 is a cross-sectional view of the electrical connector along line 19-19 of FIG. 18, FIG. 20 is a cross-sectional view of the electrical connector of FIG. 18 combined with a cable, and FIG. 21 is a cross-sectional view of the electrical connector along line 21-21 of FIG. 20.

[0056] The electrical connector 10d is combined with the cable 20, thereby being configured to form a cable assembly 1d together with the cable 20. The cable 20 includes a conductive core 21, an insulating layer 22, a braided mesh layer 23 (functioning as a shielding layer), and an outer layer 24 from the inside to the outside. At one end of the cable 20, the conductive core 21, the insulating layer 22, and the braided mesh layer 23 may be exposed from the outer layer 24.

[0057] The following describes the procedure for combining the cable 20 with the electrical connector 10d. First, as shown in FIGS. 18 and 19, when the cable 20 has not yet been inserted into the electrical connector 10d, the inner pressing sleeve 200d is positioned at the non-pressing position. As a result, the elastic clamping portion 220d of the inner pressing sleeve 200d is not pressed by the pressing portion 120d of the casing 100d. Thereby, a mounting through-hole H1d is formed on the side farther from the base 211d of the elastic clamping portion 220d. The inner diameter D1d of the mounting through-hole H1d is equal to or greater than the outer diameter D of the braided mesh layer 23 of the cable 20.

[0058] Next, as shown in FIGS. 20 and 21, after the cable 20 is inserted into the mounting space 111d of the housing portion 110d through the through-hole of the fastening cover portion 140d of the casing 100d, the conductive core 21 exposed from the outer layer 24 of the cable 20 is inserted into the guide component 500d. Thereafter, the cable 20, the guide component 500d, and the inner pressing sleeve 200d move together. Next, the elastic clamping portion 220d of the moving inner pressing sleeve 200d contacts the pressing portion 120d of the casing 100d and temporarily stops. At this point, if the cable 20 is continuously pushed in, the cable 20 and the guide component 500d move relative to the inner pressing sleeve 200d until the cable 20 passes through the mounting through-hole H1d and contacts the base 211d of the annular fastening portion 210d of the inner pressing sleeve 200d. Thereafter, by further pushing in the cable 20, the inner pressing sleeve 200d moves, and the elastic clamping portion 220d of the inner pressing sleeve 200d is pressed by the pressing portion 120d of the casing 100d, and a clamping hole H2d is formed on the side farther from the base 211d of the elastic clamping portion 220d. In this case, the inner diameter D1d of the mounting through-hole H1d is larger than the inner diameter D2d of the clamping hole H2d. As a result, the elastic clamping portion 220d of the inner pressing sleeve 200d firmly clamps the braided mesh layer 23 of the cable 20.

[0059] In this embodiment, the annular fastening portion 210d of the inner pressing sleeve 200d is slidable relative to the housing portion 110d of the casing 100d. As a result, the elastic clamping portion 220d forms the mounting through-hole H1d when not pressed by the pressing portion 120d of the casing 100d, and can form the clamping hole H2d when pressed by the pressing portion 120d. The inner diameter D1d of the mounting through-hole H1d is larger than the inner diameter D2d of the clamping hole H2d. With this configuration, during the process of inserting the cable 20 through the mounting space 111d of the housing portion 110d into the inner pressing sleeve 200d, the elastic clamping portion 220d of the inner pressing sleeve 200d is pressed by the pressing portion 120d of the casing 100d, and the braided mesh layer 23 of the cable 20 can be firmly clamped. As a result, it is no longer necessary to fold back the braided mesh layer 23 of the cable 20, and the elastic clamping portion 220d of the inner pressing sleeve 200d is pressed by the pressing portion 120d of the casing 100d to firmly clamp the braided mesh layer 23 of the cable 20, ensuring electrical contact between the inner pressing sleeve 200d and the braided mesh layer 23 of the cable 20. Therefore, when combining the cable 20 with the electrical connector 10d, the step of folding back the braided mesh layer 23 of the cable 20 is omitted, and the combination efficiency is improved.

[0060] In this embodiment, when it is necessary to combine the cable assembly 1d with the connector of an electronic device, in order to enable the conductive core 21 of the cable 20 to be in electrical contact with the terminal of the connector of the electronic device, it is necessary to remove the guide component 500d of the electrical connector 10d from the inner pressing sleeve 200d. Note that the guide component 500d is an optional component and may be omitted in other actual application examples.

[0061] Next, refer to FIGS. 22 and 23. FIG. 22 is an exploded view of an electrical connector according to a fifth embodiment of the present disclosure, and FIG. 23 is a cross-sectional view of the electrical connector of FIG. 22.

[0062] In this embodiment, the electrical connector 10e includes a casing 100e and an inner pressing sleeve 200e.

[0063] The casing 100e includes a housing portion 110e and a pressing portion 120e. The housing portion 110e has an attachment space 111e, and the pressing portion 120e is at least partially located within the attachment space 111e. For example, the pressing portion 120e and the housing portion 110e are made of two parts, and the pressing portion 120e extends from the attachment space 111e of the housing portion 110e to the outside of the housing portion 110e. The pressing portion 120e has an edge portion 121e bent outward at one end located within the attachment space 111e, and a flange 122e at one end located outside the attachment space 111e. The casing 100e may further include a coupling portion 130e. The coupling portion 130e is rotatably arranged on a part of the pressing portion 120e located outside the housing portion 110e, and a part of the coupling portion 130e and a part of the housing portion 110e are clamped by the edge portion 121e bent outward and the flange 122e of the pressing portion 120e. The coupling portion 130e has an internal thread structure and is combined with, for example, a connector of an electronic device (not shown).

[0064] In this embodiment, the electrical connector 10e may further include an elastic sheet 400e. The elastic sheet 400e is arranged between the coupling portion 130e and the pressing portion 120e, and stably fixes the coupling portion 130e to the pressing portion 120e.

[0065] Note that the elastic sheet 400e is an optional component and may be omitted in other embodiments.

[0066] The inner pressing sleeve 200e is slidably disposed within the mounting space 111e and includes an annular fastening portion 210e and a plurality of elastic clamping portions 220e connected to the annular fastening portion 210e. The elastic clamping portions 220e extend from the annular fastening portion 210e in the same direction and are spaced apart from each other in the circumferential direction of the annular fastening portion 210e. The thickness of the elastic clamping portion 220e gradually increases in a direction away from the annular fastening portion 210e. In other embodiments, the thickness of the elastic clamping portion 220e may gradually decrease or remain uniform in a direction away from the annular fastening portion 210e.

[0067] In this embodiment, the electrical connector 10e may further include a guide component 500e. The guide component 500e is made of an electrical insulating material such as plastic, for example. The annular fastening portion 210e of the inner pressing sleeve 200e may have a mounting hole 211e, and the guide component 500e is movably and removably disposed within the mounting hole 211e. The guide component 500e is configured to guide the combination of the cable 20 (see FIG. 24).

[0068] Also, the electrical connector 10e may further include an annular elastic component 700e, and the casing 100e may further include a fastening cover portion 140e. The annular elastic component 700e is mounted to one end of the housing portion 110e via the fastening cover portion 140e, and the annular elastic component 700e is rotatable relative to the housing portion 110e and the fastening cover portion 140e. The annular elastic component 700e has a plurality of elastic arms 710e for stably fixing the cable 20. Note that the annular elastic component 700e and the fastening cover portion 140e are optional components and may be omitted in other embodiments.

[0069] Also, the electrical connector 10e may further include a fastening ring 600e. The fastening ring 600e is disposed within the mounting space 111e to stably fix the cable 20. Note that the fastening ring 600e is an optional component and may be omitted in other embodiments.

[0070] Next, refer to FIGS. 23 and 24. FIG. 24 is a cross-sectional view of the electrical connector of FIG. 23 combined with a cable. The electrical connector 10e is configured to be combined with the cable 20, thereby forming a cable assembly 1e together with the cable 20. The cable 20 includes, from the inside to the outside, a conductive core 21, an insulating layer 22, a braided mesh layer 23 (functioning as a shielding layer), and an outer layer 24. At one end of the cable 20, the conductive core 21, the insulating layer 22, and the braided mesh layer 23 may be exposed from the outer layer 24.

[0071] Hereinafter, the procedure for combining the cable 20 with the electrical connector 10e will be described. First, as shown in FIG. 23, when the cable 20 has not yet been inserted into the electrical connector 10e, the inner pressing sleeve 200e is positioned at the non-pressing position. As a result, the elastic clamping portion 220e of the inner pressing sleeve 200e is not pressed by the pressing portion 120e of the casing 100e. Thereby, a mounting through-hole H1e is formed on the side farther from the annular fastening portion 210e of the elastic clamping portion 220e. The inner diameter D1e of the mounting through-hole H1e is equal to or larger than the outer diameter D of the braided mesh layer 23 of the cable 20.

[0072] Next, as shown in FIG. 24, after the cable 20 is inserted into the mounting space 111e of the housing portion 110e through the through hole of the fastening cover portion 140e of the casing 100e, the conductive core 21 exposed from the outer layer 24 of the cable 20 is inserted into the guide component 500e. Then, the cable 20, the guide component 500e, and the inner pressing sleeve 200e move together. Next, the elastic clamping portion 220e of the moving inner pressing sleeve 200e contacts the pressing portion 120e of the casing 100e and temporarily stops. At this point, when the cable 20 is continuously pushed in, the cable 20 and the guide component 500e move relatively with respect to the inner pressing sleeve 200e until the cable 20 passes through the mounting through hole H1e and contacts the annular fastening portion 210e of the inner pressing sleeve 200e. Then, by further pushing in the cable 20, the inner pressing sleeve 200e moves, and the elastic clamping portion 220e of the inner pressing sleeve 200e is pressed by the pressing portion 120e of the casing 100e, and the clamping hole H2e is formed. In this case, the inner diameter D1e of the mounting through hole H1e is larger than the inner diameter D2e of the clamping hole H2e. As a result, the elastic clamping portion 220e of the inner pressing sleeve 200e firmly clamps the braided mesh layer 23 of the cable 20.

[0073] In this embodiment, the annular fastening portion 210e of the inner pressing sleeve 200e is slidable relative to the housing portion 110e of the casing 100e. As a result, the elastic clamping portion 220e forms the mounting through hole H1e when not pressed by the pressing portion 120e of the casing 100e, and can form the clamping hole H2e when pressed by the pressing portion 120e. The inner diameter D1e of the mounting through hole H1e is larger than the inner diameter D2e of the clamping hole H2e. With this configuration, in the process of inserting the cable 20 through the mounting space 111e of the housing portion 110e into the inner pressing sleeve 200e, the elastic clamping portion 220e of the inner pressing sleeve 200e is pressed by the pressing portion 120e of the casing 100e, and the braided mesh layer 23 of the cable 20 can be firmly clamped. As a result, it is not necessary to fold back the braided mesh layer 23 of the cable 20, and the elastic clamping portion 220e of the inner pressing sleeve 200e is pressed by the pressing portion 120e of the casing 100e to firmly clamp the braided mesh layer 23 of the cable 20, ensuring electrical contact between the inner pressing sleeve 200e and the braided mesh layer 23 of the cable 20. Therefore, when combining the cable 20 with the electrical connector 10e, the step of folding back the braided mesh layer 23 of the cable 20 is omitted, and the combination efficiency is improved.

[0074] In this embodiment, when it is necessary to combine the cable assembly 1e with the connector of an electronic device, in order for the conductive core 21 of the cable 20 to be electrically contacted with the terminal of the connector of the electronic device, it is necessary to remove the guide component 500e of the electrical connector 10e from the inner pressing sleeve 200e. Note that the guide component 500e is an optional component and may be omitted in other actual application examples.

[0075] Next, refer to FIGS. 25 and 26. FIG. 25 is an exploded view of an electrical connector according to the sixth embodiment of the present disclosure, and FIG. 26 is a cross-sectional view of the electrical connector of FIG. 25.

[0076] In this embodiment, the electrical connector 10f includes a casing 100f and an inner pressing sleeve 200f.

[0077] The casing 100f includes a housing portion 110f and a pressing portion 120f. The housing portion 110f has an attachment space 111f, and the pressing portion 120f is at least partially located within the attachment space 111f. For example, the pressing portion 120f and the housing portion 110f are made of two parts, and the pressing portion 120f extends from the attachment space 111f of the housing portion 110f to the outside of the housing portion 110f. The pressing portion 120f has an edge portion 121f bent outward at one end located within the attachment space 111f, and the pressing portion 120f has a flange 122f at one end located outside the attachment space 111f. The casing 100f may further include a coupling portion 130f. The coupling portion 130f is rotatably disposed on a part of the pressing portion 120f located outside the housing portion 110f, and a part of the coupling portion 130f and a part of the housing portion 110f are clamped by the edge portion 121f bent outward of the pressing portion 120f and the flange 122f. The coupling portion 130f has an internal thread structure and is combined with, for example, a connector of an electronic device (not shown).

[0078] In this embodiment, the electrical connector 10f may further include an elastic sheet 400f. The elastic sheet 400f is disposed between the coupling portion 130f and the pressing portion 120f and stably fixes the coupling portion 130f to the pressing portion 120f.

[0079] Note that the elastic sheet 400f is an optional component and may be omitted in other embodiments.

[0080] The inner pressing sleeve 200f is slidably disposed within the mounting space 111f and includes an annular fastening portion 210f and a plurality of elastic clamping portions 220f connected to the annular fastening portion 210f. The elastic clamping portions 220f extend from the annular fastening portion 210f in the same direction and are spaced apart from each other in the circumferential direction of the annular fastening portion 210f. The thickness of the elastic clamping portion 220f gradually increases in a direction away from the annular fastening portion 210f. In other embodiments, the thickness of the elastic clamping portion 220f may gradually decrease in a direction away from the annular fastening portion 210f or may remain uniform.

[0081] In the present embodiment, the electrical connector 10f may further include a guide component 500f. The guide component 500f is made of an electrical insulating material such as plastic, for example. The annular fastening portion 210f of the inner pressing sleeve 200f may have a mounting hole 211f, and the guide component 500f is movably and removably disposed within the mounting hole 211f. The guide component 500f is configured to guide the combination of the cable 20 (see FIG. 27).

[0082] Also, the electrical connector 10f may further include an annular elastic component 700f, and the casing 100f may further include a fastening cover portion 140f. The annular elastic component 700f is mounted to one end of the housing portion 110f via the fastening cover portion 140f, and the annular elastic component 700f is rotatable with respect to the housing portion 110f and the fastening cover portion 140f. The annular elastic component 700f has a plurality of elastic arms 710f for stably fixing the cable 20. Note that the annular elastic component 700f and the fastening cover portion 140f are optional components and may be omitted in other embodiments.

[0083] Further, the electrical connector 10f may further include a fastening ring 600f. The fastening ring 600f is disposed within the mounting space 111f. The inner diameter of the fastening ring 600f gradually increases along the direction away from the coupling portion 130f. The fastening ring 600f is configured to stably fix the cable 20. Note that the fastening ring 600f is an optional component and may be omitted in other embodiments.

[0084] Next, refer to FIGS. 26 and 27. FIG. 27 is a cross-sectional view of the electrical connector of FIG. 25 combined with a cable. The electrical connector 10f is combined with the cable 20, thereby being configured to form a cable assembly 1f together with the cable 20. The cable 20 includes, from the inside to the outside, a conductive core 21, an insulating layer 22, a braided mesh layer 23 (functioning as a shielding layer), and an outer layer 24. At one end of the cable 20, the conductive core 21, the insulating layer 22, and the braided mesh layer 23 may be exposed from the outer layer 24.

[0085] Hereinafter, the procedure for combining the cable 20 with the electrical connector 10f will be described. First, as shown in FIG. 26, when the cable 20 has not yet been inserted into the electrical connector 10f, the inner pressing sleeve 200f is positioned at the non-pressing position. As a result, the elastic clamping portion 220f of the inner pressing sleeve 200f is not pressed by the pressing portion 120f of the casing 100f. Thereby, an attachment through-hole H1f is formed on the side farther from the annular fastening portion 210f of the elastic clamping portion 220f. The inner diameter D1f of the attachment through-hole H1f is equal to or greater than the outer diameter D of the braided mesh layer 23 of the cable 20.

[0086] Next, as shown in FIG. 27, after the cable 20 is inserted into the mounting space 111f of the housing portion 110f through the through-hole of the fastening cover portion 140f of the casing 100f, the conductive core 21 exposed from the outer layer 24 of the cable 20 is inserted into the guide component 500f. Then, the cable 20, the guide component 500f, and the inner pressing sleeve 200f move together. Next, the elastic clamping portion 220f of the moving inner pressing sleeve 200f comes into contact with the pressing portion 120f of the casing 100f and temporarily stops. At this point, if the cable 20 is continuously pushed in, the cable 20 and the guide component 500f move relative to the inner pressing sleeve 200f until the cable 20 passes through the mounting through-hole H1f and contacts the annular fastening portion 210f of the inner pressing sleeve 200f. Then, by further pushing in the cable 20, the inner pressing sleeve 200f moves, and the elastic clamping portion 220f of the inner pressing sleeve 200f is pressed by the pressing portion 120f of the casing 100f, and the clamping hole H2f is formed. In this case, the inner diameter D1f of the mounting through-hole H1f is larger than the inner diameter D2f of the clamping hole H2f. As a result, the elastic clamping portion 220f of the inner pressing sleeve 200f firmly clamps the braided mesh layer 23 of the cable 20.

[0087] In this embodiment, the annular fastening portion 210f of the inner pressing sleeve 200f is slidable with respect to the housing portion 110f of the casing 100f. As a result, the elastic clamping portion 220f forms the mounting through hole H1f when not pressed by the pressing portion 120f of the casing 100f, and can form the clamping hole H2f when pressed by the pressing portion 120f. The inner diameter D1f of the mounting through hole H1f is larger than the inner diameter D2f of the clamping hole H2f. With this configuration, in the process of inserting the cable 20 through the mounting space 111f of the housing portion 110f into the inner pressing sleeve 200f, the elastic clamping portion 220f of the inner pressing sleeve 200f is pressed by the pressing portion 120f of the casing 100f, and the braided mesh layer 23 of the cable 20 can be firmly clamped. As a result, it is not necessary to fold back the braided mesh layer 23 of the cable 20, and the elastic clamping portion 220f of the inner pressing sleeve 200f is pressed by the pressing portion 120f of the casing 100f to firmly clamp the braided mesh layer 23 of the cable 20, ensuring electrical contact between the inner pressing sleeve 200f and the braided mesh layer 23 of the cable 20. Therefore, when combining the cable 20 with the electrical connector 10f, the step of folding back the braided mesh layer 23 of the cable 20 is omitted, and the combination efficiency is improved.

[0088] In this embodiment, when it is necessary to combine the cable assembly 1f with the connector of an electronic device, in order for the conductive core 21 of the cable 20 to be electrically contacted with the terminal of the connector of the electronic device, it is necessary to remove the guide component 500f of the electrical connector 10f from the inner pressing sleeve 200f. Note that the guide component 500f is an optional component and may be omitted in other actual application examples.

[0089] Next, refer to FIGS. 28 and 29. FIG. 28 is an exploded view of an electrical connector according to a seventh embodiment of the present disclosure, and FIG. 29 is a cross-sectional view of the electrical connector of FIG. 28.

[0090] In this embodiment, the electrical connector 10g includes a casing 100g and an inner pressing sleeve 200g.

[0091] The casing 100g includes a housing part 110g and a pressing part 120g. The housing part 110g has a mounting space 111g, and the pressing part 120g is at least partially located within the mounting space 111g. For example, the pressing part 120g is integrally formed with the housing part 110g and extends from the mounting space 111g of the housing part 110g to the outside of the housing part 110g. The casing 100g may further include a coupling part 130g, and the coupling part 130g has a positioning bending part 131g. The pressing part 120g has a positioning recess 121g at a portion located outside the housing part 110g. The coupling part 130g is rotatably arranged at a portion of the pressing part 120g located outside the housing part 110g via the positioning bending part 131g and the positioning recess 121g. The coupling part 130g has an internal thread structure and is combined with, for example, a connector of an electronic device (not shown).

[0092] The inner pressing sleeve 200g is slidably arranged within the mounting space 111g and includes an annular fastening part 210g and a plurality of elastic clamping parts 220g connected to the annular fastening part 210g. The elastic clamping parts 220g extend from the annular fastening part 210g in the same direction and are spaced apart from each other in the circumferential direction of the annular fastening part 210g. The thickness of the elastic clamping parts 220g gradually increases in a direction away from the annular fastening part 210g. In other embodiments, the thickness of the elastic clamping parts 220g may gradually decrease or remain uniform in a direction away from the annular fastening part 210g.

[0093] In this embodiment, the electrical connector 10g may further include a guide component 500g. The guide component 500g is made of, for example, an electrical insulating material such as plastic. The annular fastening part 210g of the inner pressing sleeve 200g may have a mounting hole 211g, and the guide component 500g is movably and removably arranged within the mounting hole 211g. The guide component 500g is configured to guide the combination of the cable 20 (see FIG. 30).

[0094] Further, the electrical connector 10g may further include an annular elastic component 700g, and the casing 100g may further include a fastening cover portion 140g. The annular elastic component 700g is mounted on one end of the housing portion 110g via the fastening cover portion 140g, and the annular elastic component 700g is rotatable with respect to the housing portion 110g and the fastening cover portion 140g. The annular elastic component 700g has a plurality of elastic arms 710g for stably fixing the cable 20. Note that the annular elastic component 700g and the fastening cover portion 140g are optional components and may be omitted in other embodiments.

[0095] Further, the electrical connector 10g may further include a fastening ring 600g. The fastening ring 600g is disposed in the mounting space 111g to stably fix the cable 20. Note that the fastening ring 600g is an optional component and may be omitted in other embodiments.

[0096] Next, refer to FIGS. 29 and 30. FIG. 30 is a cross-sectional view of the electrical connector of FIG. 28 combined with a cable. The electrical connector 10g is combined with the cable 20, thereby being configured to form a cable assembly 1g together with the cable 20. The cable 20 includes, from the inside to the outside, a conductive core 21, an insulating layer 22, a braided mesh layer 23 (functioning as a shielding layer), and an outer layer 24. At one end of the cable 20, the conductive core 21, the insulating layer 22, and the braided mesh layer 23 may be exposed from the outer layer 24.

[0097] The following describes the procedure for combining the cable 20 with the electrical connector 10g. First, as shown in FIG. 29, when the cable 20 has not yet been inserted into the electrical connector 10g, the inner pressing sleeve 200g is positioned at the non-pressing position. As a result, the elastic clamping portion 220g of the inner pressing sleeve 200g is not pressed by the pressing portion 120g of the casing 100g. Thereby, a mounting through-hole H1g is formed on the side farther from the annular fastening portion 210g of the elastic clamping portion 220g. The inner diameter D1g of the mounting through-hole H1g is equal to or greater than the outer diameter D of the braided mesh layer 23 of the cable 20.

[0098] Next, as shown in FIG. 30, after the cable 20 is inserted into the mounting space 111g of the housing portion 110g through the through-hole of the fastening cover portion 140g of the casing 100g, the conductive core 21 exposed from the outer layer 24 of the cable 20 is inserted into the guide component 500g. Thereafter, the cable 20, the guide component 500g, and the inner pressing sleeve 200g move together. Next, the elastic clamping portion 220g of the moving inner pressing sleeve 200g contacts the pressing portion 120g of the casing 100g and temporarily stops. At this point, if the cable 20 is continuously pushed in, the cable 20 and the guide component 500g move relative to the inner pressing sleeve 200g until the cable 20 passes through the mounting through-hole H1g and contacts the annular fastening portion 210g of the inner pressing sleeve 200g. Thereafter, by further pushing in the cable 20, the inner pressing sleeve 200g moves, and the elastic clamping portion 220g of the inner pressing sleeve 200g is pressed by the pressing portion 120g of the casing 100g, and a clamping hole H2g is formed. In this case, the inner diameter D1g of the mounting through-hole H1g is larger than the inner diameter D2g of the clamping hole H2g. As a result, the elastic clamping portion 220g of the inner pressing sleeve 200g firmly clamps the braided mesh layer 23 of the cable 20.

[0099] In this embodiment, the annular fastening portion 210g of the inner pressing sleeve 200g is slidable with respect to the housing portion 110g of the casing 100g. As a result, when the elastic clamping portion 220g of the inner pressing sleeve 200g is not pressed by the pressing portion 120g of the casing 100g, the mounting through-hole H1g is formed, and when it is pressed by the pressing portion 120g, the clamping hole H2g can be formed. The inner diameter D1g of the mounting through-hole H1g is larger than the inner diameter D2g of the clamping hole H2g. With this configuration, in the process of inserting the cable 20 through the mounting space 111g of the housing portion 110g into the inner pressing sleeve 200g, the elastic clamping portion 220g of the inner pressing sleeve 200g is pressed by the pressing portion 120g of the casing 100g, and the braided mesh layer 23 of the cable 20 can be firmly clamped. As a result, it is not necessary to fold back the braided mesh layer 23 of the cable 20, and the elastic clamping portion 220g of the inner pressing sleeve 200g is pressed by the pressing portion 120g of the casing 100g to firmly clamp the braided mesh layer 23 of the cable 20, ensuring electrical contact between the inner pressing sleeve 200g and the braided mesh layer 23 of the cable 20. Therefore, when combining the cable 20 with the electrical connector 10g, the step of folding back the braided mesh layer 23 of the cable 20 is omitted, and the combination efficiency is improved.

[0100] In this embodiment, when it is necessary to combine the cable assembly 1g with the connector of the electronic device, in order for the conductive core 21 of the cable 20 to be electrically contacted with the terminal of the connector of the electronic device, it is necessary to remove the guide component 500g of the electrical connector 10g from the inner pressing sleeve 200g. Note that the guide component 500g is an optional component and may be omitted in other actual application examples.

[0101] Next, refer to FIGS. 31 to 33. FIG. 31 is a perspective view of an electrical connector according to the eighth embodiment of the present disclosure, FIG. 32 is an exploded view of the electrical connector of FIG. 31, and FIG. 33 is a perspective view of the inner pressing sleeve of FIG. 32.

[0102] In this embodiment, the electrical connector 10h includes a casing 100h and an inner pressing sleeve 200h.

[0103] Next, refer to FIGS. 32 and 34. FIG. 34 is a cross-sectional view of the electrical connector of FIG. 31.

[0104] The casing 100h includes a housing portion 110h and a pressing portion 120h. The housing portion 110h has a mounting space 111h, and the pressing portion 120h is at least partially located within the mounting space 111h. For example, the housing portion 110h includes a plurality of ring portions 112h and a plurality of folding portions 113h. The ring portions 112h are axially connected via the folding portions 113h, and the ring portions 112h and the folding portions 113h together form the mounting space 111h. The pressing portion 120h and the housing portion 110h are made of two parts, and the pressing portion 120h extends from the mounting space 111h of the housing portion 110h to the outside of the housing portion 110h. The pressing portion 120h has an edge portion 121h bent outward at one end located within the mounting space 111h. The casing 100h may further include a coupling portion 130h, and the electrical connector 10h may further include an O-ring 300h. The coupling portion 130h is rotatably disposed on a part of the pressing portion 120h located outside the housing portion 110h, and a part of the coupling portion 130h and a part of the housing portion 110h are clamped by the edge portion 121h bent outward of the pressing portion 120h and the O-ring 300h. The coupling portion 130h has an internal thread structure and is combined with, for example, a connector of an electronic device (not shown).

[0105] Note that the O-ring 300h is an optional component and may be omitted in other embodiments.

[0106] As shown in FIGS. 32 to 34, the inner pressing sleeve 200h is slidably disposed within the mounting space 111h and includes an annular fastening portion 210h and a plurality of elastic clamping portions 220h connected to the annular fastening portion 210h. The elastic clamping portions 220h extend from the annular fastening portion 210h in the same direction and are spaced apart from each other in the circumferential direction of the annular fastening portion 210h. Each of the elastic clamping portions 220h includes a peripheral portion 221h and an inner arm portion 222h. In one elastic clamping portion 220h, two ends of the peripheral portion 221h are connected to the annular fastening portion 210h, the peripheral portion 221h and the annular fastening portion 210h together form an opening O, and the inner arm portion 222h is connected to the peripheral portion 221h and is located within the opening O. Further, the inner pressing sleeve 200h may also include a plurality of elastic contact portions 230h. The elastic contact portions 230h are connected to the annular fastening portion 210h. Each of the elastic contact portions 230h is located within the opening O and is positioned opposite to the inner arm portion 222h.

[0107] In the present embodiment, the electrical connector 10h may further include a guide component 500h. The guide component 500h is made of an electrical insulating material such as plastic. The annular fastening portion 210h of the inner pressing sleeve 200h may have a mounting hole 211h, and the guide component 500h is movably and removably disposed within the mounting hole 211h. The guide component 500h is configured to guide the combination of the cable 20 (see FIG. 35).

[0108] Next, refer to FIGS. 34 to 36. FIGS. 35 and 36 are cross-sectional views of the electrical connector of FIG. 34 combined with a cable.

[0109] The electrical connector 10h is combined with the cable 20 so as to form a cable assembly 1h together with the cable 20. The cable 20 includes a conductive core 21, an insulating layer 22, a braided mesh layer 23 (functioning as a shielding layer), and an outer layer 24 from the inside to the outside. At one end of the cable 20, the conductive core 21, the insulating layer 22, and the braided mesh layer 23 may be exposed from the outer layer 24.

[0110] The following describes the procedure for combining the cable 20 with the electrical connector 10h. First, as shown in FIG. 34, when the cable 20 has not yet been inserted into the electrical connector 10h, the inner pressing sleeve 200h is positioned at the non-pressing position. As a result, the elastic clamping portion 220h of the inner pressing sleeve 200h is not pressed by the pressing portion 120h of the casing 100h. Thereby, the mounting through-hole H1h is formed on the side farther from the annular fastening portion 210h of the elastic clamping portion 220h. The inner diameter D1h of the mounting through-hole H1h is equal to or greater than the outer diameter D of the braided mesh layer 23 of the cable 20.

[0111] Next, as shown in FIG. 35, after the cable 20 is inserted into the mounting space 111h of the housing portion 110h, the conductive core 21 exposed from the outer layer 24 of the cable 20 is inserted into the guide component 500h. Thereafter, the cable 20, the guide component 500h, and the inner pressing sleeve 200h move together. Next, the elastic clamping portion 220h of the moving inner pressing sleeve 200h contacts the pressing portion 120h of the casing 100h and temporarily stops. At this point, if the cable 20 is continuously pushed in, the cable 20 and the guide component 500h move relative to the inner pressing sleeve 200h until the cable 20 passes through the mounting through-hole H1h and contacts the annular fastening portion 210h of the inner pressing sleeve 200h, and the elastic contact portion 230h contacts the braided mesh layer 23 of the cable 20. Thereafter, by further pushing in the cable 20, the inner pressing sleeve 200h moves, and the elastic clamping portion 220h of the inner pressing sleeve 200h is pressed by the pressing portion 120h of the casing 100h, and the clamping hole H2h is formed. In this case, the inner diameter D1h of the mounting through-hole H1h is larger than the inner diameter of the clamping hole H2h (see FIG. 11). As a result, the elastic clamping portion 220h of the inner pressing sleeve 200h firmly clamps the braided mesh layer 23 of the cable 20.

[0112] Next, as shown in FIG. 36, when the casing 100h is clamped along the axial direction of the electrical connector 10h using a tool, the folding portion 113h of the housing portion 110h of the casing 100h is folded in the axial and radial directions toward the central axis, and the outer layer 24 of the cable 20 is pressed. In this way, the combination of the cable 20 and the electrical connector 10h is completed.

[0113] In this embodiment, the annular fastening portion 210h of the inner pressing sleeve 200h is slidable with respect to the housing portion 110h of the casing 100h. As a result, the elastic clamping portion 220h forms the mounting through hole H1h when not pressed by the pressing portion 120h of the casing 100h, and can form the clamping hole H2h when pressed by the pressing portion 120h. The inner diameter D1h of the mounting through hole H1h is larger than the inner diameter of the clamping hole H2h. With this configuration, during the process of inserting the cable 20 through the mounting space 111h of the housing portion 110h into the inner pressing sleeve 200h, the elastic clamping portion 220h of the inner pressing sleeve 200h is pressed by the pressing portion 120h of the casing 100h, and the braided mesh layer 23 of the cable 20 can be firmly clamped. As a result, it is not necessary to fold back the braided mesh layer 23 of the cable 20. The elastic clamping portion 220h of the inner pressing sleeve 200h is pressed by the pressing portion 120h of the casing 100h to firmly clamp the braided mesh layer 23 of the cable 20, ensuring electrical contact between the inner pressing sleeve 200h and the braided mesh layer 23 of the cable 20. Therefore, the step of folding back the braided mesh layer 23 of the cable 20 when combining the cable 20 with the electrical connector 10h is omitted, and the combination efficiency is improved.

[0114] In this embodiment, when it is necessary to combine the cable assembly 1h with the connector of an electronic device, in order to enable the conductive core 21 of the cable 20 to be in electrical contact with the terminal of the connector of the electronic device, it is necessary to remove the guide component 500h of the electrical connector 10h from the inner pressing sleeve 200h. Note that the guide component 500h is an optional component and may be omitted in other actual application examples.

[0115] Refer to FIGS. 37 and 38. FIG. 37 is a perspective view of an electrical connector according to a ninth embodiment of the present disclosure, and FIG. 38 is a cross-sectional view of the electrical connector of FIG. 37.

[0116] In this embodiment, the electrical connector 10i includes a casing 100i and an inner pressing sleeve 200i.

[0117] The casing 100i includes a housing portion 110i and a pressing portion 120i. The housing portion 110i has an installation space 111i, and the pressing portion 120i is at least partially located within the installation space 111i. For example, the housing portion 110i includes a ring portion 112i and a folding portion 113i that are axially connected to each other. The folding portion 113i has a plurality of annular grooves 1131i that are axially arranged and spaced apart from each other. The ring portion 112i and the folding portion 113i together form the installation space 111i. The pressing portion 120i and the housing portion 110i are made of two parts, and the pressing portion 120i extends from the installation space 111i of the housing portion 110i to the outside of the housing portion 110i. The pressing portion 120i has an edge portion 121i that is bent outward at one end located within the installation space 111i, and the pressing portion 120i has a flange 122i at one end located outside the installation space 111i. The casing 100i may further include a coupling portion 130i. The coupling portion 130i is rotatably arranged on a part of the pressing portion 120i located outside the housing portion 110i, and a part of the coupling portion 130i and a part of the housing portion 110i are clamped by the edge portion 121i and the flange 122i that are bent outward of the pressing portion 120i. The coupling portion 130i has an internal thread structure and is combined with, for example, a connector of an electronic device (not shown).

[0118] Since the inner pressing sleeve 200i has the same structure as the inner pressing sleeve 200h of the foregoing embodiment, a detailed introduction thereof is omitted.

[0119] In this embodiment, the electrical connector 10i may further include a guide component 500i. The combination relationship between the guide component 500i and the inner pressing sleeve 200i is the same as the relationship between the inner pressing sleeve 200h and the guide component 500h in the foregoing embodiment. Therefore, the corresponding paragraphs of the foregoing embodiment can be referred to, and the detailed description will not be repeated.

[0120] Next, refer to FIGS. 38 to 41. FIGS. 39 and 40 are cross-sectional views of the electrical connector of FIG. 38 combined with a cable, and FIG. 41 is a perspective view of the electrical connector and the cable of FIG. 40.

[0121] The electrical connector 10i is configured to be combined with a cable 20, thereby forming a cable assembly 1i together with the cable 20. The cable 20 includes, from the inside to the outside, a conductive core 21, an insulating layer 22, a braided mesh layer 23 (functioning as a shielding layer), and an outer layer 24. At one end of the cable 20, the conductive core 21, the insulating layer 22, and the braided mesh layer 23 may be exposed from the outer layer 24.

[0122] Hereinafter, the procedure for combining the cable 20 with the electrical connector 10i will be described. First, as shown in FIG. 38, when the cable 20 has not yet been inserted into the electrical connector 10i, the inner pressing sleeve 200i is positioned at a non-pressing position. As a result, the elastic clamping portion 220i of the inner pressing sleeve 200i is not pressed by the pressing portion 120i of the casing 100i. Thereby, a mounting through-hole H1i is formed on the side farther from the annular fastening portion 210i of the elastic clamping portion 220i. The inner diameter D1i of the mounting through-hole H1i is equal to or greater than the outer diameter D of the braided mesh layer 23 of the cable 20.

[0123] Next, as shown in FIG. 39, after the cable 20 is inserted into the mounting space 111i of the housing portion 110i, the conductive core 21 exposed from the outer layer 24 of the cable 20 is inserted into the guide component 500i. Thereafter, the cable 20, the guide component 500i, and the inner pressing sleeve 200i move together. Next, the elastic clamping portion 220i of the moving inner pressing sleeve 200i contacts the pressing portion 120i of the casing 100i and temporarily stops. At this point, if the cable 20 is continuously pushed in, the cable 20 and the guide component 500 move relative to the inner pressing sleeve 200i until the cable 20 passes through the mounting through-hole H1i and contacts the annular fastening portion 210i of the inner pressing sleeve 200i, and the elastic contact portion 230i contacts the braided mesh layer 23 of the cable 20. Thereafter, by further pushing in the cable 20, the inner pressing sleeve 200i moves, and the elastic clamping portion 220i of the inner pressing sleeve 200i is pressed by the pressing portion 120i of the casing 100i, and the clamping hole H2i is formed. In this case, the inner diameter D1i of the mounting through-hole H1i is larger than the inner diameter of the clamping hole H2i (see FIG. 11). As a result, the elastic clamping portion 220i of the inner pressing sleeve 200i firmly clamps the braided mesh layer 23 of the cable 20.

[0124] As shown in FIGS. 40 and 41, using a tool, the folding portion 113i of the housing portion 110i of the electrical connector 10i is clamped in the radial direction, and the folding portion 113i is folded in the radial direction into, for example, a hexagonal shape and pressed against the outer layer 24 of the cable 20. In this way, the combination of the cable 20 and the electrical connector 10i is completed. In other embodiments, the folding portion may have any geometric shape (for example, circular, triangular, etc.) for pressing against the outer layer of the cable for the combination.

[0125] In this embodiment, the annular fastening portion 210i of the inner pressing sleeve 200i is slidable relative to the housing portion 110i of the casing 100i. As a result, the elastic clamping portion 220i forms the mounting through-hole H1i when not pressed by the pressing portion 120i of the casing 100i, and can form the clamping hole H2i when pressed by the pressing portion 120i. The inner diameter D1i of the mounting through-hole H1i is larger than the inner diameter of the clamping hole H2i. With this configuration, during the process of inserting the cable 20 through the mounting space 111i of the housing portion 110i into the inner pressing sleeve 200i, the elastic clamping portion 220i of the inner pressing sleeve 200i is pressed by the pressing portion 120i of the casing 100i, and the braided mesh layer 23 of the cable 20 can be firmly clamped. As a result, it is no longer necessary to fold back the braided mesh layer 23 of the cable 20. The elastic clamping portion 220i of the inner pressing sleeve 200i is pressed by the pressing portion 120i of the casing 100i to firmly clamp the braided mesh layer 23 of the cable 20, ensuring electrical contact between the inner pressing sleeve 200i and the braided mesh layer 23 of the cable 20. Therefore, when combining the cable 20 with the electrical connector 10i, the step of folding back the braided mesh layer 23 of the cable 20 is omitted, improving the combination efficiency.

[0126] In this embodiment, when it is necessary to combine the cable assembly 1i with the connector of an electronic device, in order to enable the conductive core 21 of the cable 20 to be in electrical contact with the terminal of the connector of the electronic device, it is necessary to remove the guide component 500i of the electrical connector 10i from the inner pressing sleeve 200i. Note that the guide component 500i is an optional component and may be omitted in other actual application examples.

[0127] Next, refer to FIGS. 42 and 43. FIG. 42 is a cross-sectional view of an electrical connector according to the tenth embodiment of the present disclosure, and FIG. 43 is a cross-sectional view of the electrical connector of FIG. 42 combined with a cable.

[0128] The electrical connector 10j of this embodiment is similar to the electrical connector 10i of the previous embodiment, and the main difference between the two lies in the structure of the casing. Therefore, hereinafter, the casing 100j of the electrical connector 10j will be mainly described, and for other parts, reference will be made to the description of the previous embodiment, and it will not be repeated here.

[0129] In this embodiment, the casing 100j further includes an outer sleeve portion 150j. The outer sleeve portion 150j sleeves and presses one end of the housing portion 110j, thereby deforming the end of the housing portion 110j in the radial direction and pressing it against the outer layer 24 of the cable 20. The end of the housing portion 110j has an annular inner groove R radially connected to the mounting space 111j. The annular inner groove R is configured to accommodate a part of the cable 20.

[0130] Refer to FIG. 44. FIG. 44 is a perspective view of an inner pressing sleeve according to the 11th embodiment of the present disclosure.

[0131] The inner pressing sleeve 200k of this embodiment is similar to the inner pressing sleeve 200a shown in FIG. 2. The main difference between the two lies in the appearance. In this embodiment, the inner pressing sleeve 200k is characterized by a curved elastic clamping portion and is more suitable for clamping thinner cables. The detailed structure of the inner pressing sleeve 200k will not be further described here. It should be noted that the inner pressing sleeve 200k of this embodiment can be used as an alternative to the inner pressing sleeve of the previous embodiment.

[0132] According to the electrical connector and cable assembly described in the above embodiment, the annular fastening portion of the inner pressing sleeve is slidable with respect to the housing portion of the casing. Thereby, when the elastic clamping portion is not pressed by the pressing portion of the casing, the mounting through-hole is formed, and when it is pressed by the pressing portion, the clamping hole can be formed, and the inner diameter of the mounting through-hole is larger than the inner diameter of the clamping hole. With this configuration, in the process of inserting the cable through the mounting space of the housing portion into the inner pressing sleeve, the elastic clamping portion of the inner pressing sleeve is pressed by the pressing portion of the casing, and the braided mesh layer of the cable can be firmly clamped. As a result, it is not necessary to fold back the braided mesh layer of the cable, and the elastic clamping portion of the inner pressing sleeve is pressed by the pressing portion of the casing to firmly clamp the braided mesh layer of the cable, ensuring electrical contact between the inner pressing sleeve and the braided mesh layer of the cable. Therefore, when combining the cable with the electrical connector, the step of folding back the braided mesh layer of the cable is omitted, and the combination efficiency is improved.

[0133] In addition, the guide component of the electrical connector can guide the combination of the cables. When it is necessary to combine the cable assembly with the connector of the electronic device, it is necessary to remove the guide component of the electrical connector from the inner pressing sleeve so that the conductive core of the cable can be electrically contacted with the terminal of the connector of the electronic device.

[0134] It is obvious to those skilled in the art that various modifications and changes can be made to the present disclosure. The present specification and examples are intended to be regarded as exemplary embodiments only, and the scope of the present disclosure is shown by the following utility model registration claims and their equivalents.
