Description

TECHNICAL FIELD

[0001] The utility model relates to an electric connector and a cable assembly. BACKGROUND

[0002] In the past, when assembling the cable in the electric connector, the user needs to fold the braided mesh layer of the cable backward first, so that the inner sleeve of the electric connector is easily inserted between the insulating layer and the braided mesh layer of the cable, to ensure the electrical contact relationship between the inner sleeve and the braided mesh layer of the cable. However, such assembly method will result in poor assembly efficiency, so the researchers in the field are working to solve the aforementioned problems. SUMMARY

[0003] The utility model provides a kind of electric connector and cable assembly, its structure can make cable assembly assembly efficiency improve.

[0004] One embodiment of the utility model discloses an electric connector for assembling a cable, comprising a shell and a pressing inner sleeve. The shell comprises a shell part and a pressing part, and the shell part has an assembly space, and the pressing part is at least partially located in the assembly space. The pressing inner sleeve is located in the assembly space and comprises a fixed ring part and at least one elastic clamping part connected thereto. The fixed ring part can slide relative to the shell part to form an assembly opening when the at least one elastic clamping part is not pressed by the pressing part, and to form a clamping opening when the at least one elastic clamping part is pressed by the pressing part. The inner diameter of the assembly opening is larger than that of the clamping opening.

[0005] Another embodiment of the utility model discloses an electric connector for assembling a cable. The electric connector comprises a shell and a pressing inner sleeve. The shell comprises a shell part and a pressing part. The shell part has an assembly space. The pressing part is at least partially located in the assembly space. The pressing inner sleeve is located in the assembly space and comprises a fixed ring part and at least one elastic clamping part connected thereto. The fixed ring part can slide relative to the shell part to form an assembly opening when the at least one elastic clamping part is not pressed by the pressing part, and to form a clamping opening when the at least one elastic clamping part is pressed by the pressing part. The inner diameter of the assembly opening is larger than that of the clamping opening.

[0006] According to the disclosed electrical connector and cable assembly of the above embodiments, the fixed ring portion of the pressing inner sleeve can slide relative to the shell portion of the shell member to form an assembly passage when the elastic clamping portion is not pressed by the pressing portion of the shell member, and to form a clamping passage when the elastic clamping portion is pressed by the pressing portion of the shell member. The inner diameter of the assembly passage is larger than the inner diameter of the clamping passage, which can drive the elastic clamping portion of the pressing inner sleeve to be pressed by the pressing portion of the shell member during the process of assembling the cable into the pressing inner sleeve through the assembly space of the shell portion, and the braided mesh layer of the cable. In this way, without folding the braided mesh layer of the cable backward, the braided mesh layer of the cable is pressed by the elastic clamping portion of the pressing inner sleeve to ensure the electrical contact relationship between the pressing inner sleeve and the braided mesh layer of the cable. Therefore, the step of folding the braided mesh layer of the cable backward during the process of assembling the cable into the electrical connector is reduced, so that the assembly efficiency can be improved.

[0098] Please see FIGS. 1-3 . FIG. 1 This is a perspective view of an electrical connector disclosed according to a first embodiment of the present invention. FIG. 2 for FIG. 1 Exploded view of the electrical connector. FIG. 3 for FIG. 2 A three-dimensional view of the tight inner lining.

[0099] In this embodiment, the electrical connector 10a includes a housing 100a and a tight inner bushing 200a.

[0100] Next, please refer to FIG. 2 and FIG. 4 . FIG. 4 for FIG. 1A cross-sectional view of the electrical connector 10a is shown. The housing 100a includes a housing portion 110a and a pressing portion 120a. The housing portion 110a has an assembly space 111a, and the pressing portion 120a is at least partially located in the assembly space 111a. For example, the pressing portion 120a is integrally formed with the housing portion 110a, and the pressing portion 120a extends from the assembly space 111a of the housing portion 110a to outside of the housing portion 110a. The housing 100a can further include a coupling portion 130a, and the electrical connector 10a can further include a positioning member 300a. The coupling portion 130a is rotatably disposed on the portion of the pressing portion 120a located outside of the housing portion 110a by the positioning member 300a. The coupling portion 130a has an internal thread structure to engage with a connector (not shown) of an electronic device, for example.

[0101] It should be noted that the positioning member 300a is an optional element, and can be omitted in other embodiments.

[0102] As shown in FIGS. 2-4 , the pressing inner sleeve 200a is slidably located in the assembly space 111a, and includes a fixed ring portion 210a and a plurality of elastic clamping portions 220a connected thereto. The elastic clamping portions 220a extend from the fixed ring portion 210a in the same direction, and the elastic clamping portions 220a are separated from each other in the circumferential direction of the fixed ring portion 210a. The thickness of the elastic clamping portions 220a gradually increases in the direction away from the fixed ring portion 210a. In other embodiments, the thickness of the elastic clamping portions 220a gradually decreases in the direction away from the fixed ring portion 210a or the thickness of the elastic clamping portions 220a remains constant.

[0103] In the present embodiment, the electrical connector 10a can further include a guide member 500a. The guide member 500a is made of, for example, an electrically insulating material such as plastic. The fixed ring portion 210a of the pressing inner sleeve 200a can have an assembly hole 211a, and the guide member 500a is movably and detachably disposed in the assembly hole 211a. The guide member 500a is used to guide the assembly of an electrical cable 20 (see FIG. 5 ).

[0104] In addition, the electrical connector 10a can further include an annular elastic member 700a, and the housing 100a can further include a cover portion 140a. The annular elastic member 700a is assembled to one end of the housing portion 110a by the cover portion 140a, and the annular elastic member 700a is rotatable relative to the housing portion 110a and the cover portion 140a. The annular elastic member 700a has a plurality of elastic arms 710a to secure the electrical cable 20. It should be noted that the annular elastic member 700a and the cover portion 140a are optional elements, and can be omitted in other embodiments.

[0105] Next, please refer to FIG. 4 and FIG. 5 . FIG. 5 isFIG. 4 A cross-sectional view of an electrical connector and cable assembly. The electrical connector 10a is used for assembling the cable 20, thereby forming a cable assembly 1a together with the cable 20. The cable 20, from the inside out, sequentially includes a conductive core 21, an insulating layer 22, a braided mesh layer 23 (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 are exposed outside the outer layer 24.

[0106] The following describes the process of assembling cable 20 into electrical connector 10a. First, as... FIG. 4 As shown, with the cable 20 not inserted into the electrical connector 10a, the tight inner sleeve 200a is initially placed in an unpressurized position, so that the elastic clamping portions 220a of the tight inner sleeve 200a are not pressed by the pressing portions 120a of the housing 100a, thereby forming an assembly opening H1a on the side of these elastic clamping portions 220a away from the retaining ring portion 210a. The inner diameter D1a of the assembly opening H1a is equal to or greater than the outer diameter D of the braided mesh layer 23 of the cable 20.

[0107] Next, as FIG. 5 As shown, after the cable 20 enters the assembly space 111a of the housing 110a through the through hole of the cover portion 140a of the housing 100a, the conductive core 21 of the cable 20 exposed outside the outer layer 24 is inserted into the guide member 500a. Then, the cable 20, the guide member 500a, and the tight inner bushing 200a move together. Next, the elastic clamping portions 220a of the moving tight inner bushing 200a contact the pressing portions 120a of the housing 100a and are temporarily stopped. At this time, by continuing to push the cable 20, the cable 20 and the guide member 500a can move relative to the tight inner bushing 200a until the cable 20 contacts the retaining ring portion 210a of the tight inner bushing 200a through the assembly port H1a. Next, by continuing to push the cable 20, the tight inner sleeve 200a can be moved, causing the elastic clamping portions 220a of the tight inner sleeve 200a to be pressed by the pressing portions 120a of the housing 100a, forming a clamping opening H2a, wherein the inner diameter D1a of the assembly opening H1a is larger than the inner diameter D2a of the clamping opening H2a. In this way, the elastic clamping portions 220a of the tight inner sleeve 200a tightly clamp the braided mesh layer 23 of the cable 20.

[0108] In the present embodiment, the assembly passage H1a is formed when the elastic clamping portion 220a is not pressed by the pressing portion 120a of the shell member 100a, and the clamping passage H2a is formed when the elastic clamping portion 220a is pressed by the pressing portion 120a of the shell member 100a, by the slippage of the fixing ring portion 210a of the pressing inner sleeve 200a relative to the shell portion 110a of the shell member 100a. The inner diameter D1a of the assembly passage H1a is larger than the inner diameter D2a of the clamping passage H2a. During the assembly of the cable 20 into the pressing inner sleeve 200a through the assembly space 111a of the shell portion 110a, the elastic clamping portion 220a of the pressing inner sleeve 200a is pressed by the pressing portion 120a of the shell member 100a, and the braided mesh layer 23 of the cable 20 is pressed. In this way, the braided mesh layer 23 of the cable 20 is pressed by the elastic clamping portion 220a of the pressing inner sleeve 200a, and the electrical contact between the pressing inner sleeve 200a and the braided mesh layer 23 of the cable 20 is ensured without folding the braided mesh layer 23 of the cable 20 backward. Therefore, the folding step of the braided mesh layer 23 of the cable 20 during the assembly of the cable 20 into the electrical connector 10a is reduced, and the assembly efficiency is improved.

[0109] In the present embodiment, when the cable assembly 1a is assembled to the connector of an electronic device, the guide member 500a of the electrical connector 10a is removed from the pressing inner sleeve 200a, so that the conductive core 21 of the cable 20 can be in electrical contact with the terminal in the connector of the electronic device. It should be noted that the guide member 500a is an optional element, and can be omitted in other practical application examples.

[0110] Next, please refer to FIG. 6 and FIG. 7 , FIG. 6 is an exploded view of the electrical connector according to the second embodiment of the present application. FIG. 7 is FIG. 6 a perspective view of the pressing inner sleeve.

[0111] In the present embodiment, the electrical connector 10b comprises a shell member 100b and a pressing inner sleeve 200b.

[0112] Next, please refer to FIG. 6 and FIG. 8 . FIG. 8 is FIG. 6A cross-sectional view of an electrical connector. The housing 100b includes a housing portion 110b and a pressing portion 120b. The housing portion 110b has an assembly space 111b, and the pressing portion 120b is at least partially located within the assembly space 111b. For example, the pressing portion 120b is integrally formed and connected to the housing portion 110b, and extends from within the assembly space 111b of the housing portion 110b to the outside of the housing portion 110b. The housing portion 100b may also include a coupling portion 130b, and the electrical connector 10b may also include a positioning member 300b. The coupling portion 130b is rotatably disposed by the positioning member 300b at the portion of the pressing portion 120b located outside the housing portion 110b. The coupling portion 130b has an internal thread structure for engagement, for example, with a connector (not shown) of an electronic device.

[0113] It should be noted that the positioning element 300b is an optional element and may be omitted in other embodiments.

[0114] like FIGS. 6-8 As shown, the tight inner sleeve 200b is slidably located within the assembly space 111b and includes a connected retaining ring portion 210b and a plurality of elastic clamping portions 220b. These elastic clamping portions 220b extend from the retaining ring portion 210b in the same direction and are separated from each other in the circumferential direction of the retaining ring portion 210b. Each of these elastic clamping portions 220b includes a peripheral portion 221b and a clamping arm portion 222b. For one elastic clamping portion 220b, both ends of the peripheral portion 221b are connected to the retaining ring portion 210b, and the peripheral portion 221b and the retaining ring portion 210b together form a movable groove O. The clamping arm portion 222b is connected to the peripheral portion 221b and located within the movable groove O. In other embodiments, the clamping arm portion 222b may be directly connected to the retaining ring portion 210b.

[0115] In this embodiment, the electrical connector 10b may further include a guide 500b. The guide 500b is made of, for example, an electrically insulating material, such as plastic. The retaining ring 210b of the tight-fitting inner sleeve 200b may have an assembly hole 211b, in which the guide 500b is movably and detachably disposed. The guide 500b is used to guide a cable 20 (please refer to...). FIG. 10 Assembly of ).

[0116] Furthermore, the electrical connector 10b may also include an annular elastic member 700b, and the housing 100b may also include a cover 140b. The annular elastic member 700b is assembled to one end of the housing 110b via the cover 140b, and the annular elastic member 700b is rotatable relative to the housing 110b and the cover 140b. The annular elastic member 700b has a plurality of spring arms 710b to secure the cable 20. It should be noted that the annular elastic member 700b and the cover 140b are optional components and may be omitted in other embodiments.

[0118] The electrical connector 10b is used for assembling the electrical cable 20, so that the electrical connector 10b and the electrical cable 20 together form an electrical cable assembly 1b. The electrical cable 20 comprises, from inside to outside, a conductive core 21, an insulating layer 22, a braided layer 23 (shield layer) and an outer layer 24. At one end of the electrical cable 20, the conductive core 21, the insulating layer 22 and the braided layer 23 can be exposed outside the outer layer 24.

[0119] The process of assembling the electrical cable 20 to the electrical connector 10b will be described below. First, as shown in FIG. 8 , 9 , the pressing inner sleeve 200b is first placed in an uncompressed position, so that the elastic clamping portions 220b of the pressing inner sleeve 200b are not pressed by the pressing portions 120b of the shell 100b, to form an assembly opening H1b on the side of the elastic clamping portions 220b away from the fixed ring portion 210b, when the electrical cable 20 is not assembled into the electrical connector 10b.

[0120] Next, as shown in FIG. 10 , 11As shown, after the cable 20 is inserted into the assembly space 111b of the housing 110b from the through hole of the cover 140b of the housing 100b, the conductive core 21 of the cable 20 exposed outside the outer layer 24 is inserted into the guide 500b, and then the cable 20, the guide 500b and the pressing inner sleeve 200b are moved together. Then, the elastic clamping portions 220b of the moving pressing inner sleeve 200b contact the abutting portion 120b of the housing 100b and are temporarily stopped. At this time, the cable 20 is continuously pushed, so that the cable 20 and the guide 500b are moved relative to the pressing inner sleeve 200b until the cable 20 contacts the fixed ring portion 210b of the pressing inner sleeve 200b through the assembly opening H1b. In the process that the cable 20 contacts the fixed ring portion 210b of the pressing inner sleeve 200b through the assembly opening H1b, the clamping arm portions 222b of the elastic clamping portions 220b of the pressing inner sleeve 200b are spread by the braided mesh layer 23 of the cable 20. Then, the cable 20 is continuously pushed, so that the pressing inner sleeve 200b is moved, and the peripheral portions 221b of the elastic clamping portions 220b of the pressing inner sleeve 200b are inwardly retracted under the abutting of the abutting portion 120b of the housing 100b, so that the clamping arm portions 222b of the elastic clamping portions 220b form a clamping opening H2b, and the inner diameter D1b of the assembly opening H1b is greater than the inner diameter D2b of the clamping opening H2b. In this way, the elastic clamping portions 220b of the pressing inner sleeve 200b tightly clamp the braided mesh layer 23 of the cable 20.

[0121] In the embodiment, the fixed ring portion 210b of the pressing inner sleeve 200b can slide relative to the housing 100b, so that the elastic clamping portions 220b form the assembly opening H1b when not being abutted by the abutting portion 120b of the housing 100b, and form the clamping opening H2b when being abutted by the abutting portion 120b, and the inner diameter D1b of the assembly opening H1b is greater than the inner diameter D2b of the clamping opening H2b. In the process that the cable 20 is assembled into the pressing inner sleeve 200b through the assembly space 111b of the housing 110b, the elastic clamping portions 220b of the pressing inner sleeve 200b are abutted by the abutting portion 120b of the housing 100b, and the braided mesh layer 23 of the cable 20 is pressed. In this way, without folding the braided mesh layer 23 of the cable 20 backward, the braided mesh layer 23 of the cable 20 is pressed by the elastic clamping portions 220b of the pressing inner sleeve 200b under the abutting of the abutting portion 120b of the housing 100b, so as to ensure the electrical contact relationship between the pressing inner sleeve 200b and the braided mesh layer 23 of the cable 20. Therefore, the step of folding the braided mesh layer 23 of the cable 20 backward in the process of assembling the cable 20 into the electrical connector 10b is reduced, so that the assembly efficiency is improved.

[0122] In this embodiment, when the cable assembly 1b needs to be assembled to the connector of the electronic device, the guide 500b of the electrical connector 10b needs to be removed from the compression inner sleeve 200b first, so that the conductive core 21 of the cable 20 can be in electrical contact with the terminal in the connector of the electronic device. It should be noted that the guide 500b is an optional element, and can be omitted in other practical application examples.

[0123] Next, please refer to FIG. 12 and FIG. 13 . FIG. 12 is an exploded view of the electrical connector according to the third embodiment of the present application. FIG. 13 is FIG. 12 a perspective view of the compression inner sleeve.

[0124] In this embodiment, the electrical connector 10c comprises a housing 100c and a compression inner sleeve 200c.

[0125] Next, please refer to FIG. 12 and FIG. 14 . FIG. 14 is FIG. 12 a sectional view of the electrical connector.

[0126] The housing 100c comprises a housing portion 110c and a pressing portion 120c. The housing portion 110c has an assembly space 111c, and the pressing portion 120c is at least partially located in the assembly space 111c. For example, the pressing portion 120c is integrally connected to the housing portion 110c, and the pressing portion 120c extends from the assembly space 111c of the housing portion 110c to the outside of the housing portion 110c. The housing 100c can further comprise a coupling portion 130c, and the electrical connector 10c can further comprise a positioning member 300c. The coupling portion 130c is rotatably arranged on the portion of the pressing portion 120c located outside the housing portion 110c through the positioning member 300c. The coupling portion 130c has an internal threaded structure to engage with the connector (not shown) of the electronic device, for example.

[0127] It should be noted that the positioning member 300c is an optional element, and can be omitted in other embodiments.

[0128] As shown in FIGS. 12-14 , the compression inner sleeve 200c is slidably located in the assembly space 111c, and comprises a fixed ring portion 210c and a plurality of elastic clamping portions 220c connected thereto. The elastic clamping portions 220c extend from the fixed ring portion 210c in the same direction, and the elastic clamping portions 220c are separated from each other in the circumferential direction of the fixed ring portion 210c. The elastic clamping portions 220c are wavy.

[0129] In this embodiment, the electrical connector 10c may further include a guide 500c. The guide 500c is made of, for example, an electrically insulating material, such as plastic. The retaining ring 210c of the tight-fitting inner sleeve 200c may have an assembly hole 211c, in which the guide 500c is movably and detachably disposed. The guide 500c is used to guide a cable 20 (please refer to...). FIG. 15 Assembly of ).

[0130] Furthermore, the electrical connector 10c may also include an annular elastic member 700c, and the housing 100c may also include a cover 140c. The annular elastic member 700c is assembled to one end of the housing 110c via the cover 140c, and the annular elastic member 700c is rotatable relative to the housing 110c and the cover 140c. The annular elastic member 700c has a plurality of spring arms 710c to secure the cable 20. It should be noted that the annular elastic member 700c and the cover 140c are optional components and may be omitted in other embodiments.

[0131] Next, please refer to FIG. 14 and FIG. 15 . FIG. 15 for FIG. 12 A cross-sectional view of an electrical connector and cable assembly. The electrical connector 10c is used for assembling the cable 20, thereby forming a cable assembly 1c together with the cable 20. The cable 20, from the inside out, sequentially includes a conductive core 21, an insulating layer 22, a braided mesh layer 23 (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 are exposed outside the outer layer 24.

[0132] The following describes the process of assembling cable 20 into electrical connector 10c. First, as... FIG. 14 As shown, with the cable 20 not inserted into the electrical connector 10c, the tight inner sleeve 200c is initially placed in an unpressurized position, so that the elastic clamping portions 220c of the tight inner sleeve 200c are not pressed by the pressing portions 120c of the housing 100c, thereby forming an assembly opening H1c on the side of these elastic clamping portions 220c away from the retaining ring portion 210c. The inner diameter D1c of the assembly opening H1c is equal to or greater than the outer diameter D of the braided mesh layer 23 of the cable 20.

[0133] Next, as FIG. 15As shown, after the cable 20 is inserted into the assembly space 111c of the housing 110c from the through hole of the cover 140c of the housing 100c, the conductive core 21 of the cable 20 exposed outside the outer layer 24 is inserted into the guide 500c, and then the cable 20, the guide 500c and the pressing inner sleeve 200c are moved together. Then, the elastic clamping portions 220c of the moving pressing inner sleeve 200c contact the abutting portion 120c of the housing 100c and are temporarily stopped. At this time, the cable 20 is continuously pushed to move the cable 20 and the guide 500c relative to the pressing inner sleeve 200c until the cable 20 contacts the fixed ring portion 210c of the pressing inner sleeve 200c through the assembly opening H1c. Then, the cable 20 is continuously pushed to move the pressing inner sleeve 200c, so that the elastic clamping portions 220c of the pressing inner sleeve 200c are abutted by the abutting portion 120c of the housing 100c to form a clamping opening H2c, wherein the inner diameter D1c of the assembly opening H1c is larger than the inner diameter D2c of the clamping opening H2c. In this way, the elastic clamping portions 220c of the pressing inner sleeve 200c tightly clamp the braided layer 23 of the cable 20.

[0134] In the present embodiment, by the arrangement that the fixed ring portion 210c of the pressing inner sleeve 200c can slide relative to the housing 110c of the housing 100c to form the assembly opening H1c when the elastic clamping portions 220c are not abutted by the abutting portion 120c of the housing 100c, and to form the clamping opening H2c when the elastic clamping portions 220c are abutted by the abutting portion 120c, and the inner diameter D1c of the assembly opening H1c is larger than the inner diameter D2c of the clamping opening H2c, the elastic clamping portions 220c of the pressing inner sleeve 200c can be abutted by the abutting portion 120c of the housing 100c to press the braided layer 23 of the cable 20 during the process of inserting the cable 20 into the pressing inner sleeve 200c through the assembly space 111c of the housing 110c. In this way, the braided layer 23 of the cable 20 does not need to be folded back to be pressed by the elastic clamping portions 220c of the pressing inner sleeve 200c abutted by the abutting portion 120c of the housing 100c, so as to ensure the electrical contact relationship between the pressing inner sleeve 200c and the braided layer 23 of the cable 20. Therefore, the step of folding back the braided layer 23 of the cable 20 during the process of assembling the cable 20 into the electrical connector 10c is reduced, so as to improve the assembly efficiency.

[0135] In the present embodiment, when the cable assembly 1c needs to be assembled to the connector of an electronic device, the guide 500c of the electrical connector 10c needs to be removed from the pressing inner sleeve 200c, so that the conductive core 21 of the cable 20 can be electrically contacted with the terminal in the connector of the electronic device. It should be noted that the guide 500c is an optional element, and can be omitted in other practical application examples.

[0136] Next, refer to FIG. 16 and FIG. 17 , FIG. 16 is an exploded view of the electrical connector according to the fourth embodiment of the present application. FIG. 17 is FIG. 16 a perspective view of the pressing inner sleeve.

Depending on actual design, the elastic clamping portions 220d can be connected to any face of the annular wall 212d in the movable grooves 2121d.

[0141] In this embodiment, the electrical connector 10d can further include a guide member 500d. The guide member 500d is made of, for example, an electrically insulating material such as plastic.

[0142] In addition, the electrical connector 10d can further include an annular elastic member 700d, and the housing member 100d can further include a cover portion 140d. The annular elastic member 700d is assembled to one end of the housing portion 110d through the cover portion 140d, and the annular elastic member 700d is rotatable relative to the housing portion 110d and the cover portion 140d. The annular elastic member 700d has a plurality of elastic arms 710d to secure the cable 20. It should be noted that the annular elastic member 700d and the cover portion 140d are optional elements, and can be omitted in other embodiments.

[0143] Next, referring to FIG. 18 and FIG. 21 . FIG. 19 is a sectional view of the electrical connector shown along the cutting plane line 19-19 of FIG. 18 . FIG. 20 is a sectional view of the assembly of the electrical connector and the cable shown along the cutting plane line 20-20 of FIG. 18 . FIG. 21 is a sectional view of the electrical connector shown along the cutting plane line 21-21 of FIG. 20 .

[0144] The electrical connector 10d is used for the assembly of the cable 20, so that the electrical connector 10d and the cable 20 together form a cable assembly 1d. The cable 20 sequentially includes, from the inside to the outside, a conductive core 21, an insulating layer 22, a braided layer 23 (shield layer), and an outer layer 24. At one end of the cable 20, the conductive core 21, the insulating layer 22, and the braided layer 23 can be exposed outside the outer layer 24.

[0145] The process of assembling the cable 20 to the electrical connector 10d will be described below. First, as shown in FIG. 18 , 19 , in the state that the cable 20 is not assembled into the electrical connector 10d, the pressing inner sleeve 200d is first placed in an uncompressed position, so that the elastic clamping portions 220d of the pressing inner sleeve 200d are not pressed by the pressing portions 120d of the housing member 100d, to form an assembly opening H1d on the side of the elastic clamping portions 220d away from the base 211d. The inner diameter D1d of the assembly opening H1d is equal to or greater than the outer diameter D of the braided layer 23 of the cable 20.

[0146] Next, as shown in FIG. 20 , 21As shown, after the cable 20 is inserted into the assembly space 111d of the housing 110d from the through hole of the cover 140d of the housing 100d, the conductive core 21 of the cable 20 exposed outside the outer layer 24 is inserted into the guide 500d, and then the cable 20, the guide 500d and the pressing inner sleeve 200d are moved together. Then, the elastic clamping portions 220d of the moving pressing inner sleeve 200d contact the abutting portion 120d of the housing 100d and are temporarily stopped. At this time, the cable 20 is continuously pushed to move the cable 20 and the guide 500d relative to the pressing inner sleeve 200d until the cable 20 contacts the base 211d of the fixed ring portion 210d of the pressing inner sleeve 200d through the assembly opening H1d. Then, the cable 20 is continuously pushed to move the pressing inner sleeve 200d so that the elastic clamping portions 220d of the pressing inner sleeve 200d are abutted by the abutting portion 120d of the housing 100d to form a clamping opening H2d on the side of the elastic clamping portions 220d away from the base 211d, wherein the inner diameter D1d of the assembly opening H1d is larger than the inner diameter D2d of the clamping opening H2d. In this way, the elastic clamping portions 220d of the pressing inner sleeve 200d tightly clamp the braided layer 23 of the cable 20.

[0147] In the present embodiment, the fixed ring portion 210d of the pressing inner sleeve 200d can slide relative to the housing portion 110d of the housing 100d to form the assembly opening H1d when the elastic clamping portions 220d are not abutted by the abutting portion 120d of the housing 100d and to form the clamping opening H2d when the elastic clamping portions 220d are abutted by the abutting portion 120d, and the inner diameter D1d of the assembly opening H1d is larger than the inner diameter D2d of the clamping opening H2d, so that the elastic clamping portions 220d of the pressing inner sleeve 200d are abutted by the abutting portion 120d of the housing 100d to press the braided layer 23 of the cable 20 during the process of inserting the cable 20 into the pressing inner sleeve 200d through the assembly space 111d of the housing portion 110d. In this way, the braided layer 23 of the cable 20 does not need to be folded back to press the braided layer 23 of the cable 20 by the elastic clamping portions 220d of the pressing inner sleeve 200d abutted by the abutting portion 120d of the housing 100d to ensure the electrical contact between the pressing inner sleeve 200d and the braided layer 23 of the cable 20. Therefore, the step of folding back the braided layer 23 of the cable 20 during the process of assembling the cable 20 into the electrical connector 10d is reduced, and the assembly efficiency is improved.

[0148] In this embodiment, when the cable assembly Id is required to be assembled to the connector of the electronic device, the guide 500d of the electrical connector 10d is required to be removed from the compression inner sleeve 200d, so that the conductive core 21 of the cable 20 can be electrically contacted with the terminal in the connector of the electronic device. It should be noted that the guide 500d is an optional element, and can be omitted in other practical application examples.

[0149] Next, please refer to FIG. 22 and FIG. 23 . FIG. 22 is an exploded view of the electrical connector according to the fifth embodiment of the present application. FIG. 23 is FIG. 22 a sectional view of the electrical connector.

[0150] In this embodiment, the electrical connector 10e comprises a housing 100e and a compression inner sleeve 200e.

[0151] The housing 100e comprises a housing portion 110e and a pressing portion 120e. The housing portion 110e has an assembly space 111e, and the pressing portion 120e is at least partially located in the assembly space 111e. For example, the pressing portion 120e and the housing portion 110e are two-piece elements, and the pressing portion 120e extends from the assembly space 111e of the housing portion 110e to outside of the housing portion 110e.

[0152] In this embodiment, the electrical connector 10e can further comprise a spring sheet 400e arranged between the coupling portion 130e and the pressing portion 120e to stably fix the coupling portion 130e to the pressing portion 120e.

[0153] It should be noted that the spring sheet 400e is an optional element, and can be omitted in other embodiments.

[0154] The pressing inner sleeve 200e is slidably located in the assembly space 111e, and comprises a fixed ring portion 210e and a plurality of elastic clamping portions 220e connected to the fixed ring portion 210e. The elastic clamping portions 220e extend from the fixed ring portion 210e in the same direction, and are separated from each other in the circumferential direction of the fixed ring portion 210e. The thickness of the elastic clamping portions 220e gradually increases in the direction away from the fixed ring portion 210e. In other embodiments, the thickness of the elastic clamping portions 220e gradually decreases in the direction away from the fixed ring portion 210e or remains constant.

[0155] In the present embodiment, the electrical connector 10e further comprises a guide member 500e. The guide member 500e is made of, for example, an electrically insulating material such as plastic. The fixed ring portion 210e of the pressing inner sleeve 200e can have an assembly hole 211e, and the guide member 500e is movably and detachably arranged in the assembly hole 211e. The guide member 500e is used to guide the assembly of the electrical cable 20 (see FIG. 24 ).

[0156] In addition, the electrical connector 10e further comprises an annular elastic member 700e, and the housing member 100e further comprises a cover portion 140e. The annular elastic member 700e is assembled to one end of the housing portion 110e through the cover portion 140e, and the annular elastic member 700e is rotatable relative to the housing portion 110e and the cover portion 140e. The annular elastic member 700e has a plurality of elastic arms 710e to secure the electrical cable 20. It should be noted that the annular elastic member 700e and the cover portion 140e are optional elements, and can be omitted in other embodiments.

[0157] Further, the electrical connector 10e further comprises a fixed ring 600e arranged in the assembly space 111e to secure the electrical cable 20. It should be noted that the fixed ring 600e is an optional element, and can be omitted in other embodiments.

[0158] Next, please refer to FIG. 23 and FIG. 24 . FIG. 24 The cross-sectional view of the electrical connector and the electrical cable assembly is shown in FIG. 23 . The electrical connector 10e is used to assemble the electrical cable 20, so that the electrical connector 10e and the electrical cable 20 together form an electrical cable assembly 1e. The electrical cable 20 comprises, from the inside to the outside, a conductive core 21, an insulating layer 22, a braided mesh layer 23 (shielding layer), and an outer layer 24. At one end of the electrical cable 20, the conductive core 21, the insulating layer 22, and the braided mesh layer 23 can be exposed outside the outer layer 24.

[0159] The process of assembling the electrical cable 20 to the electrical connector 10e will be described below. First, as shown in FIG. 23As shown, in the state that the cable 20 is not assembled into the electrical connector 10e, the pressing inner sleeve 200e is first placed in an uncompressed position, and the elastic clamping portions 220e of the pressing inner sleeve 200e are not pressed by the pressing portions 120e of the shell member 100e, so that an assembly passage H1e is formed on the side of the fixed ring portion 210e of the pressing inner sleeve 200e. The inner diameter D1e of the assembly passage H1e is equal to or greater than the outer diameter D of the braided mesh layer 23 of the cable 20.

[0160] Next, as shown, FIG. 24 the cable 20 is inserted into the assembly space 111e of the shell member 100e from the through hole of the cover portion 140e of the shell member 100e, and the conductive core 21 of the cable 20 exposed outside the outer layer 24 is inserted into the guide member 500e, and then the cable 20, the guide member 500e and the pressing inner sleeve 200e are moved together. Next, the elastic clamping portions 220e of the moving pressing inner sleeve 200e contact the pressing portions 120e of the shell member 100e and are temporarily stopped. At this time, the cable 20 is continuously pushed to move the cable 20 and the guide member 500e relative to the pressing inner sleeve 200e until the cable 20 contacts the fixed ring portion 210e of the pressing inner sleeve 200e through the assembly passage H1e. Next, the cable 20 is continuously pushed to move the pressing inner sleeve 200e, so that the elastic clamping portions 220e of the pressing inner sleeve 200e are pressed by the pressing portions 120e of the shell member 100e to form a clamping passage H2e, wherein the inner diameter D1e of the assembly passage H1e is greater than the inner diameter D2e of the clamping passage H2e. In this way, the elastic clamping portions 220e of the pressing inner sleeve 200e tightly clamp the braided mesh layer 23 of the cable 20.

[0161] In this embodiment, the retaining ring 210e of the tight inner sleeve 200e can slide relative to the shell portion 110e of the shell 100e, so that the elastic clamping portion 220e is not pressed by the pressing portion 120e of the shell 100e to form an assembly opening H1e, and the elastic clamping portion 220e is pressed by the pressing portion 120e to form a clamping opening H2e. The inner diameter D1e of the assembly opening H1e is larger than the inner diameter D2e of the clamping opening H2e. During the process of the cable 20 being inserted into the tight inner sleeve 200e through the assembly space 111e of the shell 110e, the elastic clamping portion 220e of the tight inner sleeve 200e is driven to be pressed by the pressing portion 120e of the shell 100e, thereby tightening the braided mesh layer 23 of the cable 20. In this way, without folding the braided mesh layer 23 of the cable 20 backward, the braided mesh layer 23 of the cable 20 can be pressed by the elastic clamping part 220e of the tight inner sleeve 200e and the pressing part 120e of the shell 100e, thus ensuring the electrical contact between the tight inner sleeve 200e and the braided mesh layer 23 of the cable 20. Therefore, the step of folding the braided mesh layer 23 of the cable 20 backward during the assembly of the cable 20 to the electrical connector 10e is reduced, thereby improving assembly efficiency.

[0162] In this embodiment, when the cable assembly 1e needs to be connected to the connector of the electronic device, the guide 500e of the electrical connector 10e needs to be removed from the tight inner sleeve 200e so that the conductive core 21 of the cable 20 can make electrical contact with the terminals inside the connector of the electronic device. It should be noted that the guide 500e is an optional component and may be omitted in other practical applications.

[0163] Next, please refer to FIG. 25 and FIG. 26 . FIG. 25 This is an exploded view of the electrical connector disclosed according to the sixth embodiment of the present invention. FIG. 26 for FIG. 25 A cross-sectional view of the electrical connector.

[0164] In this embodiment, the electrical connector 10f includes a housing 100f and a tight inner bushing 200f.

[0165] The shell member 100f includes a shell portion 110f and a pressing portion 120f. The shell portion 110f has an assembling space 111f, and the pressing portion 120f is at least partially located in the assembling space 111f. For example, the pressing portion 120f and the shell portion 110f are two-piece components, and the pressing portion 120f extends out of the shell portion 110f from the assembling space 111f. The pressing portion 120f has an outwardly bent edge 121f at one end thereof in the assembling space 111f, and has a radial flange 122f at the other end thereof out of the assembling space 111f.

[0166] In the present embodiment, the electrical connector 10f can further include a spring sheet 400f disposed between the coupling portion 130f and the pressing portion 120f to stably secure the coupling portion 130f to the pressing portion 120f.

[0167] It should be noted that the spring sheet 400f is an optional component, and can be omitted in other embodiments.

[0168] The pressing inner sleeve 200f is slidably located in the assembling space 111f, and includes a fixing ring portion 210f and a plurality of elastic clamping portions 220f connected to each other. The elastic clamping portions 220f extend from the fixing ring portion 210f in the same direction, and the elastic clamping portions 220f are separated from each other in the circumferential direction of the fixing ring portion 210f. The thickness of the elastic clamping portions 220f gradually increases in the direction away from the fixing ring portion 210f. In other embodiments, the thickness of the elastic clamping portions 220f gradually decreases in the direction away from the fixing ring portion 210f, or the thickness of the elastic clamping portions 220f remains constant.

[0169] In the present embodiment, the electrical connector 10f can further include a guide member 500f. The guide member 500f is made of, for example, an electrically insulating material, such as plastic. The fixing ring portion 210f of the pressing inner sleeve 200f can have an assembling hole 211f, and the guide member 500f is movably and detachably disposed in the assembling hole 211f. The guide member 500f is used to guide the assembly of an electrical cable 20 (see FIG. 27 ).

[0170] Furthermore, the electrical connector 10f may also include an annular elastic member 700f, and the housing 100f may also include a cover 140f. The annular elastic member 700f is assembled to one end of the housing 110f via the cover 140f, and the annular elastic member 700f is rotatable relative to the housing 110f and the cover 140f. The annular elastic member 700f has multiple spring arms 710f to secure the cable 20. It should be noted that the annular elastic member 700f and the cover 140f are optional components and may be omitted in other embodiments.

[0171] Furthermore, the electrical connector 10f may also include a retaining ring 600f, which is disposed within the assembly space 111f, and the inner diameter of the retaining ring 600f gradually increases in the direction away from the coupling portion 130f. The retaining ring 600f is used to secure the cable 20. It should be noted that the retaining ring 600f is an optional component and may be omitted in other embodiments.

[0172] Next, please refer to FIG. 26 and FIG. 27 . FIG. 27 for FIG. 25 A cross-sectional view of an electrical connector and cable assembly. The electrical connector 10f is used for assembling the cable 20, thereby forming a cable assembly 1f together with the cable 20. The cable 20, from the inside out, sequentially includes a conductive core 21, an insulating layer 22, a braided mesh layer 23 (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 are exposed outside the outer layer 24.

[0173] The following describes the process of assembling cable 20 onto electrical connector 10f. First, as... FIG. 26 As shown, with the cable 20 not inserted into the electrical connector 10f, the tight inner sleeve 200f is initially placed in an unpressurized position, so that the elastic clamping portions 220f of the tight inner sleeve 200f are not pressed by the pressing portions 120f of the housing 100f, thus forming an assembly opening H1f on the side of these elastic clamping portions 220f away from the retaining ring portion 210f. The inner diameter D1f of the assembly opening H1f is equal to or greater than the outer diameter D of the braided mesh layer 23 of the cable 20.

[0174] Next, as FIG. 27As shown, after the cable 20 is inserted into the assembly space 111f of the housing 110f from the through hole of the cover 140f of the housing 100f, the conductive core 21 of the cable 20 exposed outside the outer layer 24 is inserted into the guide 500f, and then the cable 20, the guide 500f and the pressing inner sleeve 200f are moved together. Then, the elastic clamping portions 220f of the moving pressing inner sleeve 200f contact the abutting portion 120f of the housing 100f and are temporarily stopped. At this time, the cable 20 is continuously pushed to move the cable 20 and the guide 500f relative to the pressing inner sleeve 200f until the cable 20 contacts the fixed ring portion 210f of the pressing inner sleeve 200f through the assembly opening H1f. Then, the cable 20 is continuously pushed to move the pressing inner sleeve 200f, so that the elastic clamping portions 220f of the pressing inner sleeve 200f are abutted by the abutting portion 120f of the housing 100f to form a clamping opening H2f, wherein the inner diameter D1f of the assembly opening H1f is greater than the inner diameter D2f of the clamping opening H2f. In this way, the elastic clamping portions 220f of the pressing inner sleeve 200f tightly clamp the braided layer 23 of the cable 20.

[0175] In the present embodiment, by the arrangement that the fixed ring portion 210f of the pressing inner sleeve 200f can slide relative to the housing 110f of the housing 100f to form the assembly opening H1f when the elastic clamping portions 220f are not abutted by the abutting portion 120f of the housing 100f, and to form the clamping opening H2f when the elastic clamping portions 220f are abutted by the abutting portion 120f, and the inner diameter D1f of the assembly opening H1f is greater than the inner diameter D2f of the clamping opening H2f, the elastic clamping portions 220f of the pressing inner sleeve 200f can be abutted by the abutting portion 120f of the housing 100f to press the braided layer 23 of the cable 20 during the process of inserting the cable 20 into the pressing inner sleeve 200f through the assembly space 111f of the housing 110f. In this way, the braided layer 23 of the cable 20 does not need to be folded back to be pressed by the elastic clamping portions 220f of the pressing inner sleeve 200f abutted by the abutting portion 120f of the housing 100f to ensure the electrical contact between the pressing inner sleeve 200f and the braided layer 23 of the cable 20. Therefore, the step of folding back the braided layer 23 of the cable 20 during the process of assembling the cable 20 into the electrical connector 10f is reduced, and the assembly efficiency is improved.

[0176] In the present embodiment, when the cable assembly 1f needs to be assembled to the connector of an electronic device, the guide 500f of the electrical connector 10f needs to be removed from the pressing inner sleeve 200f so that the conductive core 21 of the cable 20 can be electrically contacted with the terminal in the connector of the electronic device. It should be noted that the guide 500f is an optional element, and can be omitted in other embodiments.

[0177] Next, refer to FIG. 28 and FIG. 29 . FIG. 28 is an exploded view of the electrical connector according to the seventh embodiment of the present application. FIG. 29 is FIG. 28 a sectional view of the electrical connector.

[0179] The housing 100g comprises a housing portion 110g and a pressing portion 120g. The housing portion 110g has an assembling space 111g, and the pressing portion 120g is at least partially located in the assembling space 111g. For example, the pressing portion 120g is integrally connected to the housing portion 110g, and the pressing portion 120g extends out of the housing portion 110g from the assembling space 111g of the housing portion 110g. The housing 100g can further comprise a coupling portion 130g.

The coupling portion 130g is rotatably arranged on the portion of the pressing portion 120g located out of the housing portion 110g through the positioning bend portion 131g and the positioning groove 121g. The coupling portion 130g has an internal thread structure to engage with a connector (not shown) of an electronic device, for example.

[0180] The pressing inner sleeve 200g is slidably located in the assembling space 111g, and comprises a fixing ring portion 210g and a plurality of elastic clamping portions 220g connected to each other. The elastic clamping portions 220g extend from the fixing ring portion 210g in the same direction, and the elastic clamping portions 220g are separated from each other in the circumferential direction of the fixing ring portion 210g. The thickness of the elastic clamping portions 220g gradually increases in the direction away from the fixing ring portion 210g. In other embodiments, the thickness of the elastic clamping portions 220g gradually decreases in the direction away from the fixing ring portion 210g or the thickness of the elastic clamping portions 220g remains constant.

[0181] In this embodiment, the electrical connector 10g can further comprise a guide member 500g. The guide member 500g is made of electrically insulating material, such as plastic, for example. The fixing ring portion 210g of the pressing inner sleeve 200g can have an assembling hole 211g, and the guide member 500g is movably and detachably arranged in the assembling hole 211g. The guide member 500g is used to guide the assembling of an electrical cable 20 (see FIG. 30 ).

[0182] Furthermore, the electrical connector 10g may also include an annular elastic member 700g, and the housing 100g may also include a cover 140g. The annular elastic member 700g is assembled to one end of the housing 110g via the cover 140g, and the annular elastic member 700g is rotatable relative to the housing 110g and the cover 140g. The annular elastic member 700g has a plurality of spring arms 710g to secure the cable 20. It should be noted that the annular elastic member 700g and the cover 140g are optional components and may be omitted in other embodiments.

[0183] Furthermore, the electrical connector 10g may also include a retaining ring 600g, which is disposed within the assembly space 111g to secure the cable 20. It should be noted that the retaining ring 600g is an optional component and may be omitted in other embodiments.

[0184] Next, please refer to FIG. 29 and FIG. 30 . FIG. 30 for FIG. 28 A cross-sectional view of an electrical connector and cable assembly. The electrical connector 10g is used for assembling the cable 20, so that the electrical connector 10g and the cable 20 together form a cable assembly 1g. The cable 20, from the inside out, sequentially includes a conductive core 21, an insulating layer 22, a braided mesh layer 23 (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 are exposed outside the outer layer 24.

[0185] The following will describe the process of assembling cable 20 onto electrical connector 10g. First, as... FIG. 29 As shown, with the cable 20 not inserted into the electrical connector 10g, the tight inner bushing 200g is initially placed in an uncompressed position, and the elastic clamping portions 220g of the tight inner bushing 200g are not pressed by the pressing portions 120g of the housing 100g, so that an assembly opening H1g is formed on the side of these elastic clamping portions 220g away from the retaining ring portion 210g. The inner diameter D1g of the assembly opening H1g is equal to or greater than the outer diameter D of the braided mesh layer 23 of the cable 20.

[0186] Next, as FIG. 30As shown, after the cable 20 is inserted into the assembly space 111g of the housing 110g from the through hole of the cover 140g of the housing 100g, the conductive core 21 of the cable 20 exposed outside the outer layer 24 is inserted into the guide 500g, and then the cable 20, the guide 500g and the pressing inner sleeve 200g are moved together. Then, the elastic clamping portions 220g of the moving pressing inner sleeve 200g contact the abutting portion 120g of the housing 100g and are temporarily stopped. At this time, the cable 20 is continuously pushed to move the cable 20 and the guide 500g relative to the pressing inner sleeve 200g until the cable 20 contacts the fixed ring portion 210g of the pressing inner sleeve 200g through the assembly opening H1g. Then, the cable 20 is continuously pushed to move the pressing inner sleeve 200g, so that the elastic clamping portions 220g of the pressing inner sleeve 200g are abutted by the abutting portion 120g of the housing 100g to form a clamping opening H2g, wherein the inner diameter D1g of the assembly opening H1g is larger than the inner diameter D2g of the clamping opening H2g. In this way, the elastic clamping portions 220g of the pressing inner sleeve 200g tightly clamp the braided layer 23 of the cable 20.

[0187] In the present embodiment, the fixed ring portion 210g of the pressing inner sleeve 200g can slide relative to the housing 100g, so that the elastic clamping portions 220g form the assembly opening H1g when not abutted by the abutting portion 120g of the housing 100g, and form the clamping opening H2g when abutted by the abutting portion 120g, and the inner diameter D1g of the assembly opening H1g is larger than the inner diameter D2g of the clamping opening H2g. In the process of inserting the cable 20 into the pressing inner sleeve 200g through the assembly space 111g of the housing 110g, the elastic clamping portions 220g of the pressing inner sleeve 200g are abutted by the abutting portion 120g of the housing 100g to press the braided layer 23 of the cable 20. In this way, without folding the braided layer 23 of the cable 20 backward, the braided layer 23 of the cable 20 is pressed by the elastic clamping portions 220g of the pressing inner sleeve 200g abutted by the abutting portion 120g of the housing 100g to ensure the electrical contact between the pressing inner sleeve 200g and the braided layer 23 of the cable 20. Therefore, the step of folding the braided layer 23 of the cable 20 backward in the process of assembling the cable 20 into the electrical connector 10g is reduced, so that the assembly efficiency is improved.

[0188] In the present embodiment, when the cable assembly 1g needs to be assembled to the connector of an electronic device, the guide 500g of the electrical connector 10g needs to be removed from the pressing inner sleeve 200g, so that the conductive core 21 of the cable 20 can be electrically contacted with the terminal in the connector of the electronic device. It should be noted that the guide 500g is an optional element, and can be omitted in other practical application examples.

[0193] It should be noted that the O-ring 300h is an optional element, and can be omitted in other embodiments.

[0194] As FIGS. 32-34As shown, the pressing inner sleeve 200h is slidably located in the assembling space 111h, and comprises a fixed ring portion 210h and a plurality of elastic clamping portions 220h connected to the fixed ring portion 210h. The elastic clamping portions 220h extend from the fixed ring portion 210h in the same direction, and are separated from each other in the circumferential direction of the fixed ring portion 210h. Each of the elastic clamping portions 220h comprises a peripheral portion 221h and a clamping arm portion 222h. For one of the elastic clamping portions 220h, two ends of the peripheral portion 221h are connected to the fixed ring portion 210h, the peripheral portion 221h and the fixed ring portion 210h jointly form a movable slot O, and the clamping arm portion 222h is connected to the peripheral portion 221h and located in the movable slot O.

Each of the elastic contact portions 230h is located in the movable slot O and opposite to the clamping arm portion 222h.

[0195] In this embodiment, the electrical connector 10h further comprises a guide member 500h. The guide member 500h is made of, for example, an electrically insulating material, such as plastic. The fixed ring portion 210h of the pressing inner sleeve 200h can have an assembling hole 211h, and the guide member 500h is movably and detachably arranged in the assembling hole 211h. The guide member 500h is used to guide the assembling of an electrical cable 20 (see FIG. 35 ) to the electrical connector 10h.

[0196] Next, please refer to FIGS. 34-36 . FIG. 35 and FIG. 36 are FIG. 34 cross-sectional views of the electrical connector and the electrical cable.

[0197] The electrical connector 10h is used for assembling the electrical cable 20, so that the electrical connector 10h and the electrical cable 20 jointly form an electrical cable assembly 1h. The electrical cable 20 comprises, from inside to outside, a conductive core 21, an insulating layer 22, a braided layer 23 (shield layer), and an outer layer 24. At one end of the electrical cable 20, the conductive core 21, the insulating layer 22, and the braided layer 23 can be exposed outside the outer layer 24.

[0198] The process of assembling the electrical cable 20 to the electrical connector 10h will be described below. First, as shown in FIG. 34 , in the state that the electrical cable 20 is not assembled into the electrical connector 10h, the pressing inner sleeve 200h is first placed in an uncompressed position, so that the elastic clamping portions 220h of the pressing inner sleeve 200h are not pressed by the pressing portions 120h of the shell 100h, and a assembling passage H1h is formed at the side of the elastic clamping portions 220h away from the fixed ring portion 210h. The inner diameter D1h of the assembling passage H1h is equal to or greater than the outer diameter D of the braided layer 23 of the electrical cable 20.

[0199] Next, as shown inFIG. 35 As shown, after the cable 20 is put into the assembling space 111h of the shell portion 110h, the conductive core 21 of the cable 20 exposed outside the outer layer 24 is inserted into the guide 500h, and then the cable 20, the guide 500h and the pressing inner sleeve 200h are moved together. Next, the elastic clamping portions 220h of the moving pressing inner sleeve 200h contact the abutting portions 120h of the shell member 100h and are temporarily stopped. At this time, the cable 20 is continuously pushed to move the cable 20 and the guide 500h relative to the pressing inner sleeve 200h until the cable 20 contacts the fixed ring portion 210h of the pressing inner sleeve 200h through the assembling opening Hlh, and the elastic contact portion 230h contacts the braided mesh layer 23 of the cable 20. Next, the cable 20 is continuously pushed to move the pressing inner sleeve 200h, so that the elastic clamping portions 220h of the pressing inner sleeve 200h are abutted by the abutting portions 120h of the shell member 100h to form a clamping opening H2h with the clamping arm portions 222h of the elastic clamping portions 220h, wherein the inner diameter Dlh of the assembling opening Hlh is greater than the inner diameter of the clamping opening H2h (as shown in FIG. 11 In this way, the elastic clamping portions 220h of the pressing inner sleeve 200h tightly clamp the braided mesh layer 23 of the cable 20.

[0200] Then, as shown in FIG. 36 , the tool is used to clamp the shell member 100h along the axial direction of the electrical connector 10h, so that the collapse portions 113h of the shell portion 110h of the shell member 100h collapse along the axial direction and towards the central axis, so that the collapse portions 113h abut the outer layer 24 of the cable 20. In this way, the assembly of the cable 20 and the electrical connector 10h is completed.

[0201] In the present embodiment, the assembly passage Hlh is formed when the elastic clamping portion 220h is not pressed by the pressing portion 120h of the shell member 100h by allowing the fixing ring portion 210h of the pressing inner sleeve 200h to slide relative to the shell portion 110h of the shell member 100h, and the clamping passage H2h is formed when the elastic clamping portion 220h is pressed by the pressing portion 120h of the shell member 100h. The inner diameter Dlh of the assembly passage Hlh is greater than the inner diameter of the clamping passage H2h, so that the braided mesh layer 23 of the cable 20 can be pressed by the elastic clamping portion 220h of the pressing inner sleeve 200h during assembly of the cable 20 into the assembly space 111h of the shell portion 110h of the shell member 100h. Thus, the braided mesh layer 23 of the cable 20 can be pressed by the elastic clamping portion 220h of the pressing inner sleeve 200h without being folded back, so that the electrical contact between the pressing inner sleeve 200h and the braided mesh layer 23 of the cable 20 can be ensured. Therefore, the step of folding back the braided mesh layer 23 of the cable 20 during assembly of the cable 20 into the electrical connector 10h can be reduced, so that the assembly efficiency can be improved.

[0202] In the present embodiment, when the cable assembly 1h is to be assembled to a terminal of an electronic device, the guide member 500h of the electrical connector 10h is removed from the pressing inner sleeve 200h, so that the conductive core 21 of the cable 20 can be in electrical contact with a terminal in the terminal of the electronic device. It should be noted that the guide member 500h is an optional element, and can be omitted in other practical examples.

The pressing portion 120i and the shell portion 110i are two-piece components, and the pressing portion 120i extends from the assembly space 111i of the shell portion 110i to the outside of the shell portion 110i. One end of the pressing portion 120i in the assembly space 111i has an outwardly bent edge 121i, and the other end of the pressing portion 120i outside the assembly space 111i has a radial flange 122i. The shell member 100i can further comprise a coupling portion 130i. The coupling portion 130i is rotatably arranged on the portion of the pressing portion 120i outside the shell portion 110i, and part of the coupling portion 130i and part of the shell portion 110i are clamped by the outwardly bent edge 121i and the radial flange 122i of the pressing portion 120i. The coupling portion 130i has an internal thread structure to engage with a connector (not shown) of an electronic device, for example.

[0206] The structure of the pressing inner sleeve 200i is the same as that of the pressing inner sleeve 200h of the previous embodiment, and therefore reference can be made to the relevant paragraphs of the previous embodiment without further elaboration.

[0207] In this embodiment, the electrical connector 10i can further comprise a guide member 500i. The assembly relationship between the guide member 500i and the pressing inner sleeve 200i is similar to that between the guide member 500h and the pressing inner sleeve 200h of the previous embodiment, and therefore reference can be made to the assembly relationship between the guide member 500i and the pressing inner sleeve 200i without further elaboration.

[0208] Next, please refer to FIGS. 38-41 . FIG. 39 and FIG. 40 are cross-sectional views of the electrical connector and the cable assembly of FIG. 38 . FIG. 41 are perspective views of the electrical connector and the cable of FIG. 40 .

[0209] The electrical connector 10i is used for assembling a cable 20, so that the electrical connector 10i and the cable 20 jointly form a cable assembly 1i. The cable 20 comprises, from the inside to the outside, a conductive core 21, an insulating layer 22, a braided mesh layer 23 (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 can be exposed outside the outer layer 24.

[0210] The process of assembling the cable 20 to the electrical connector 10i will be described below. First, as shown inFIG. 38 As shown, with the cable 20 not inserted into the electrical connector 10i, the tight inner bushing 200i is initially placed in an unpressurized position, so that the elastic clamping portions 220i of the tight inner bushing 200i are not pressed by the pressing portions 120i of the housing 100i, thereby forming an assembly opening H1i on the side of these elastic clamping portions 220i away from the retaining ring portion 210i. The inner diameter D1i of the assembly opening H1i is equal to or greater than the outer diameter D of the braided mesh layer 23 of the cable 20.

[0211] Next, as FIG. 39 As shown, after the cable 20 is placed into the assembly space 111i of the housing 110i, the conductive core 21 of the cable 20 exposed outside the outer layer 24 is inserted into the guide 500i, and then the cable 20, the guide 500i, and the tight inner bushing 200i move together. Next, the elastic clamping portions 220i of the moving tight inner bushing 200i contact the pressing portions 120i of the housing 100i and are temporarily stopped. At this time, by continuing to push the cable 20, the cable 20 and the guide 500i can move relative to the tight inner bushing 200i until the cable 20 contacts the retaining ring portion 210i of the tight inner bushing 200i through the assembly port H1i, and the elastic contact portion 230i contacts the braided mesh layer 23 of the cable 20. Next, by continuing to push the cable 20, the tight inner sleeve 200i can be moved, causing the elastic clamping portions 220i of the tight inner sleeve 200i to be pressed by the pressing portions 120i of the housing 100i, so that a clamping opening H2i is formed in the clamping arm portions 222i of these elastic clamping portions 220i, wherein the inner diameter D1i of the assembly opening H1i is larger than the inner diameter of the clamping opening H2i (e.g., FIG. 11 (As shown). In this way, the elastic clamping parts 220i of the tight inner liner 200i tightly clamp the braided mesh layer 23 of the cable 20.

[0212] Then, as FIG. 40 and FIG. 41 Using a tool, the recessed portion 113i of the housing 110i is radially clamped along the electrical connector 10i, causing the recessed portion 113i of the housing 110i to radially contract and form, for example, a hexagon, to press against the outer layer 24 of the cable 20. This completes the assembly of the cable 20 and the electrical connector 10i. In other embodiments, the recessed portion can be of any geometric shape (e.g., circular, triangular, etc.) to press against the outer layer of the cable for assembly.

[0213] In this embodiment, the inner sleeve 200i is forced to deform by the fixed ring portion 210i of the inner sleeve 200i being slidable relative to the shell portion 110i of the shell 100i, so that the assembly opening H1i is formed when the elastic clamping portion 220i is not pressed by the pressing portion 120i of the shell 100i, and the clamping opening H2i is formed when the elastic clamping portion 220i is pressed by the pressing portion 120i of the shell 100i. The inner diameter D1i of the assembly opening H1i is greater than the inner diameter of the clamping opening H2i, so that during assembly of the cable 20 into the assembly space 111i of the shell portion 110i, the elastic clamping portion 220i of the inner sleeve 200i is pressed by the pressing portion 120i of the shell 100i, and the braid layer 23 of the cable 20 is forced. In this way, without folding the braid layer 23 of the cable 20 back, the braid layer 23 of the cable 20 is forced by the elastic clamping portion 220i of the inner sleeve 200i being pressed by the pressing portion 120i of the shell 100i, to ensure the electrical contact between the inner sleeve 200i and the braid layer 23 of the cable 20. Therefore, the step of folding the braid layer 23 of the cable 20 back during assembly of the cable 20 into the electrical connector 10i is reduced, so that the assembly efficiency is improved.

[0214] In this embodiment, when the cable assembly 1i needs to be assembled to a connector of an electronic device, the guide 500i of the electrical connector 10i needs to be removed from the inner sleeve 200i, so that the conductive core 21 of the cable 20 can be in electrical contact with a terminal in the connector of the electronic device. It should be noted that the guide 500i is an optional element, and can be omitted in other practical application examples.

[0215] Next, referring to FIG. 42 and FIG. 43 . FIG. 42 a cross-sectional view of an electrical connector according to a tenth embodiment of the present application. FIG. 43 a cross-sectional view of an electrical connector and a cable assembly. FIG. 42

[0216] The electrical connector 10j of this embodiment is similar to the electrical connector 10i of the above-mentioned embodiment, and the difference between the two is mainly in the structure of the shell, so that the shell 100j of the electrical connector 10j of this embodiment is mainly described below, and other parts can refer to the description of the above-mentioned embodiment, and will not be described again.

[0217] In this embodiment, the shell 100j further includes an outer sleeve portion 150j, which is sleeved and pressed on one end of the shell portion 110j to force the end of the shell portion 110j to deform radially and press against the outer layer 24 of the cable 20. The end of the shell portion 110j has an annular inner groove R, which is radially communicated with the assembly space 111j, and the annular inner groove R is used to accommodate part of the cable 20. ​

[0218] Next, please refer to FIG. 44 , FIG. 44 The perspective view of the urgent inner sleeve according to the eleventh embodiment of the present application.

[0219] The urgent inner sleeve 200k of the present embodiment is similar to FIG. 2 the urgent inner sleeve 200a, and the difference between them is mainly the different shapes. The elastic clamping part of the urgent inner sleeve 200k of the present embodiment is designed in a curved shape, which is more suitable for clamping thinner cables. Therefore, the detailed structure of the urgent inner sleeve 200k of the present embodiment will not be described again. It should be noted that the urgent inner sleeve 200k of the present embodiment can replace the urgent inner sleeves of the previous embodiments.

[0220] According to the above-mentioned embodiments of the electric connector and the cable assembly, the fixing ring part of the urgent inner sleeve can slide relative to the shell part of the shell, so that the elastic clamping part forms an assembly opening when it is not pressed by the pressing part of the shell, and forms a clamping opening when it is pressed by the pressing part. The inner diameter of the assembly opening is larger than the inner diameter of the clamping opening, which can drive the elastic clamping part of the urgent inner sleeve to be pressed by the pressing part of the shell when the cable is assembled into the urgent inner sleeve through the assembly space of the shell part, and the braided mesh layer of the urgent cable. In this way, without folding the braided mesh layer of the cable backward, the braided mesh layer of the urgent cable can be pressed by the elastic clamping part of the urgent inner sleeve to ensure the electrical contact relationship between the urgent inner sleeve and the braided mesh layer of the cable. Therefore, the step of folding the braided mesh layer of the cable backward during the assembly of the cable in the electric connector is reduced, so that the assembly efficiency can be improved.

[0221] In addition, the guide of the electric connector can guide the assembly of the cable. When it is necessary to connect the cable assembly to the connector of the electronic device, it is necessary to remove the guide of the electric connector from the urgent inner sleeve, so that the conductive core of the cable can be in electrical contact with the terminal in the connector of the electronic device.
