The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0041] The present application provides a conductive cable, which is used to be pressed onto a substrate through a conductive seat. The conductive cable includes a cable unit, a signal terminal, a ground terminal and an insulating covering and shielding assembly. The conductive cable includes a signal line, a cable covering wrapped around the signal line, and a conductive copper foil wrapped around the cable covering, wherein a portion of the signal line is exposed outside the cable covering; the signal terminal abuts the signal line exposed outside the cable covering; the ground terminal abuts the conductive copper foil; the insulating covering and shielding assembly is at least respectively coated at the abutment between the ground terminal and the conductive copper foil and the abutment between the signal terminal and the signal line, and a portion of the signal terminal and a portion of the ground terminal are both exposed from the insulating covering and shielding assembly. The insulating covering and shielding assembly is used to be inserted into the pressing slot of the conductive seat, the portion of the signal terminal exposed from the insulating covering and shielding assembly is used to elastically abut against the signal contact piece of the substrate, and the portion of the ground terminal exposed from the insulating covering and shielding assembly is used to elastically abut against the ground contact piece of the substrate.
[0042] The above-mentioned conductive cable realizes signal transmission due to the abutment between the signal terminal and the signal line exposed on the periphery of the cable sheath; realizes reliable grounding return due to the abutment between the ground terminal and the conductive copper foil; and realizes reliable grounding return due to the plastic coating of the insulating sheathing shielding component at least respectively coated on the abutment between the ground terminal and the conductive copper foil and the abutment between the signal terminal and the signal line, so that the ground terminal and the conductive copper foil, the signal terminal and the signal line can all be reliably abutted and positioned. Moreover, since part of the signal terminal and part of the ground terminal are both exposed to the insulating sheathing shielding component, and the part of the signal terminal exposed to the insulating sheathing shielding component elastically abuts against the signal contact piece of the substrate, the ground terminal exposed to the insulating sheathing shielding component elastically abuts against the signal contact piece of the substrate. The part of the component elastically abuts against the grounding contact piece of the substrate, and the insulating sheathing shielding component is inserted into the compression slot of the conductive seat, so that the signal terminal and the signal contact piece of the substrate are reliably elastically abutted, and the grounding terminal and the grounding contact piece of the substrate are reliably elastically abutted. At the same time, the insulating sheathing shielding component elastically abuts against the conductive seat, so that the conductive cable can be reliably grounded and transmit signals; since the abutting points between the grounding terminal and the conductive copper foil and the abutting points between the signal terminal and the signal line are all fixed by plastic wrapping of the insulating sheathing shielding component, the overall structure of the conductive cable is relatively compact and can be independently disassembled and replaced. Compared with traditional cable assemblies, the cable assembly of the present application is smaller in size.
[0043] To better understand the technical solutions and beneficial effects of the present application, the present application is further described in detail below with reference to specific embodiments:
[0044] like Figures 1 to 4 As shown, the cable assembly 10 of one embodiment includes a substrate 100, a conductive seat 200 and a conductive cable 300. Figure 5 and Figure 5a , wherein the substrate 100 is provided with the signal contact piece 110 and the ground contact piece 120, the conductive seat 200 is connected to the substrate 100, and the conductive cable 300 is pressed onto the substrate 100 through the conductive seat 200, so that the conductive cable 300 is electrically connected to the signal contact piece 110 and the ground contact piece 120 respectively.
[0045] like Figure 4 、 Figure 6 and Figure 7 As shown, further, the conductive cable 300 includes a cable unit 310, a signal terminal 320, a ground terminal 330 and an insulating covering shielding assembly 340. Figure 8The cable unit 310 includes a signal line 312, a cable sheath 314 wrapped around the signal line 312, and a conductive copper foil 316 wrapped around the cable sheath 314. The signal line 312 is partially exposed outside the cable sheath 314. The signal terminal 320 abuts against the portion of the signal line 312 exposed outside the cable sheath 314, thereby reliably electrically connecting the signal terminal 320 and the signal line 312 and achieving reliable signal transmission. The grounding terminal 330 abuts against the conductive copper foil 316, ensuring reliable grounding of the conductive copper foil 316. The conductive base 200 defines a compression slot 202, into which the insulating sheath shielding assembly 340 is inserted. During assembly, the insulating cover shielding component 340 is inserted into the pressing slot 202 , so that the conductive base 200 presses the insulating cover shielding component 340 into the pressing slot 202 , thereby pressing the conductive cable 300 onto the substrate 100 through the conductive base 200 .
[0046] like Figure 7 、 Figure 9 and Figure 10 As shown, further, the insulating covering shielding assembly 340 is respectively overmolded at least at the abutment area between the ground terminal 330 and the conductive copper foil 316, and at the abutment area between the signal terminal 320 and the signal line 312, so that the abutment area between the ground terminal 330 and the conductive copper foil 316, and the abutment area between the signal terminal 320 and the signal line 312 are both fixed by the insulating covering shielding assembly 340. Portions of the signal terminal 320 and the ground terminal 330 are both exposed from the insulating covering shielding assembly 340. The portion of the signal terminal 320 exposed from the insulating covering shielding assembly 340 is used to elastically abut against the signal contact sheet 110, thereby reliably electrically connecting the signal terminal 320 and the signal contact sheet 110 and achieving reliable signal transmission. The portion of the grounding terminal 330 exposed from the insulating covering shielding assembly 340 is used to elastically abut against the grounding contact piece 120 , so that the grounding terminal 330 is electrically connected to the grounding contact piece 120 , thereby achieving reliable grounding return.
[0047] The above-mentioned cable assembly 10 and its conductive cable 300 realize signal transmission because the signal terminal 320 abuts against the signal line 312 exposed on the periphery of the cable sheath 314; and realizes reliable grounding return because the ground terminal 330 abuts against the conductive copper foil 316; because the insulating sheathing shielding component 340 is at least respectively coated on the abutting part between the ground terminal 330 and the conductive copper foil 316, and the abutting part between the signal terminal 320 and the signal line 312, the ground terminal 330 and the conductive copper foil 316, and the signal terminal 320 and the signal line 312 can all be reliably abutted and positioned. Moreover, since part of the signal terminal 320 and part of the ground terminal 330 are both exposed on the insulating sheathing shielding component 340, and the part of the signal terminal 320 exposed on the insulating sheathing shielding component 340 elastically abuts against the signal contact piece 110 of the substrate 100, the ground terminal 330 exposed on the insulating sheathing shielding component 340 The insulating sheathing shielding component 340 is elastically abutted against the grounding contact piece 120 of the substrate 100, and the insulating sheathing shielding component 340 is inserted into the compression slot 202 of the conductive seat 200, so that the conductive cable 300 and the conductive seat 200 can be quickly plugged and assembled, so that the signal terminal 320 and the signal contact piece 110 of the substrate 100 can be reliably elastically abutted, and the grounding terminal 330 and the grounding contact piece 120 of the substrate 100 can be reliably elastically abutted, and at the same time, the insulating sheathing shielding component 340 is elastically abutted against the conductive seat 200, so that the conductive cable 300 can be reliably grounded and transmit signals; because the abutting point between the grounding terminal 330 and the conductive copper foil 316, and the abutting point between the signal terminal 320 and the signal line 312 are all fixed by plastic wrapping with the insulating sheathing shielding component 340, the overall structure of the conductive cable 300 is relatively compact, and can be independently disassembled and replaced. Compared with the traditional cable assembly 10, the cable assembly 10 of the present application is smaller in size.
[0048] It is understood that the cable sheath 314 can be made of plastic, rubber, or other insulating materials. In this embodiment, the cable sheath 314 is made of plastic so that the cable sheath 314 can better wrap around the signal terminal 320 and provide better insulation.
[0049] It is understood that the conductive base 200 can be a metal base or a conductive base made of other materials. In this embodiment, the conductive base 200 is a metal base, so that the conductive base 200 has better conductive performance and structural strength.
[0050] like Figure 8 and Figure 9As shown, in one embodiment, there are two signal lines 312, and the two signal lines 312 form a differential signal transmission, thereby achieving differential signal transmission in the conductive cable 300. In this embodiment, there are two signal terminals 320 and two signal contact pads 110. The two signal terminals 320 respectively abut the two signal lines 312, and the two signal terminals 320 respectively abut the corresponding signal contact pads 110, achieving differential signal transmission. The two signal lines 312 are each wrapped with a cable sheath 314, and the conductive copper foil 316 is respectively wrapped around the two cable sheaths 314. That is, the cable sheaths 314 corresponding to the two signal lines 312 are wrapped with the same conductive copper foil 316. This ensures that the conductive cable 300 is reliably grounded and returned during differential signal transmission, while also reliably shielding the conductive cable 300 from external signal interference, thereby making the differential signal transmission more stable.
[0051] like Figure 6 、 Figure 8 and Figure 9 As shown, in one embodiment, the cable unit 310 further includes an insulating protective sleeve 318, which covers the conductive copper foil 316. The conductive copper foil 316 is partially exposed outside the insulating protective sleeve 318 and abuts the ground terminal 330, so that the insulating protective sleeve 318 provides insulation and protection for the conductive copper foil 316. In one embodiment, the insulating sheathing and shielding assembly 340 is also molded onto the end of the insulating protective sleeve 318 adjacent to the ground terminal 330, so that the insulating sheathing and shielding assembly 340 can better cover and secure the conductive cable 300, while also ensuring that the ground terminal 330 and the ground contact piece 120 are securely positioned and abutted.
[0052] like Figure 6 、 Figure 8 and Figure 9As shown, in one embodiment, the insulating covering shielding assembly 340 includes a grounding conductive covering member 340a and an insulating covering assembly 340b. The insulating covering assembly 340b is respectively coated with plastic at least at the abutting portion between the ground terminal 330 and the conductive copper foil 316, and at the abutting portion between the signal terminal 320 and the signal line 312. The abutting portion between the ground terminal 330 and the conductive copper foil 316, and the abutting portion between the signal terminal 320 and the signal line 312 are both fixed by the insulating covering assembly 340b, thereby reliably electrically connecting the ground terminal 330 and the conductive copper foil 316, and reliably electrically connecting the signal terminal 320 and the signal line 312. Portions of the signal terminal 320 and the ground terminal 330 are both exposed outside the insulating cover assembly 340b. Specifically, portions of the signal terminal 320 and the ground terminal 330 protrude from the outer periphery of the insulating cover assembly 340b, leaving portions of the signal terminal 320 and the ground terminal 330 exposed outside the insulating cover assembly 340b. The grounding conductive cover 340a wraps around the surface of the insulating cover assembly 340b and is electrically connected to the ground terminal 330. The grounding conductive cover 340a is inserted into the compression slot 202, abutting against the conductive base 200. Because the grounding conductive cover 340a wraps around the surface of the insulating cover assembly 340b and is electrically connected to the ground terminal 330, the grounding conductive cover 340a is reliably grounded and returned via the ground terminal 330.
[0053] like Figure 4 and Figure 5As shown, in one embodiment, there are at least two conductive cables 300 and at least two compression slots 202. The insulation covering and shielding assembly 340 of each conductive cable 300 is inserted into the corresponding compression slot 202, allowing the insulation covering and shielding assembly 340 of each conductive cable 300 to be inserted into the corresponding compression slot 202, allowing each conductive cable 300 to be individually disassembled, maintained, or replaced, thereby improving the ease of use of the cable assembly 10. The number of signal contacts 110 and the number of ground contacts 120 are both at least two. The portion of the signal terminal 320 of each conductive cable 300 exposed from the corresponding insulation covering and shielding assembly 340 elastically abuts against the corresponding signal contact 110, and the portion of the ground terminal 330 of each conductive cable 300 exposed from the corresponding insulation covering and shielding assembly 340 elastically abuts against the corresponding ground contact 120, allowing each conductive cable 300 to reliably transmit signals. In this embodiment, the grounding conductive covering 340a of each conductive cable 300 is wrapped around the surface of the corresponding insulating covering assembly 340b and electrically connected to the corresponding grounding terminal 330, and each grounding conductive covering 340a is inserted into the clamping slot 202, so that each grounding conductive covering 340a is in contact with the conductive base 200. In this way, each grounding conductive covering 340a can not only be conductively grounded through the corresponding grounding terminal 330, but also conductively grounded through the conductive base 200 and other adjacent grounding conductive coverings 340a and grounding terminals 330, thereby achieving reliable grounding and better avoiding the problem of poor grounding of any grounding conductive covering 340a affecting the signal transmission of the conductive cable 300.
[0054] like Figure 5 and Figure 7As shown, the grounding conductive covering 340a of each conductive cable 300 is further formed by bending onto the surface of the insulating covering assembly 340b, so that the grounding conductive covering 340a of each conductive cable 300 is wrapped around the surface of the corresponding insulating covering assembly 340b. To ensure that the grounding conductive covering 340a of each conductive cable 300 is securely fixed and positioned on the surface of the insulating covering assembly 340b, a bending positioning groove 341 is further formed on the surface of the insulating covering assembly 340b. A portion of the grounding conductive covering 340a of each conductive cable 300 is bent and received in the bending positioning groove 341, thereby securely fixing the grounding conductive covering 340a of each conductive cable 300 to the surface of the insulating covering assembly 340b. In this embodiment, the grounding conductive covering member 340a of each conductive cable 300 includes an integrally formed grounding conductive covering body 342 and a bent fixing portion 344. The grounding conductive covering body 342 covers the surface of the insulating covering assembly 340b. The bent fixing portion 344 is curved and located within a bent positioning groove 341, thereby securely securing the grounding conductive covering member 340a of each conductive cable 300 to the surface of the insulating covering assembly 340b. Specifically, the grounding conductive covering body 342 and the bent fixing portion 344 are integrally stamped and formed using a stamping process. This makes the grounding conductive covering member 340a of each conductive cable 300 relatively compact and easy to manufacture, while also ensuring a secure connection between the grounding conductive covering body 342 and the bent fixing portion 344. Furthermore, there are two bent fixing portions 344, both of which are connected to the grounding conductive covering body 342, and the two bent fixing portions 344 bend in opposite directions. In this embodiment, there are two bent positioning grooves 341, and the two bent fixing portions 344 are respectively located in the two bent positioning grooves 341, so that the grounding conductive covering 340a of each conductive cable 300 is more reliably fixed and positioned on the surface of the insulating covering assembly 340b.
[0055] like Figure 11 and Figure 12 As shown, further, the inner wall of the grounding conductive covering body 342 is provided with two first stop flanges 3422 arranged opposite to each other. The two first stop flanges 3422 are both in contact with the end face of the insulating covering component 340b adjacent to the ground contact piece 120, so that the inner wall of the grounding conductive covering body 342 blocks and limits the end face of the insulating covering component 340b, preventing the insulating covering component 340b from detaching in the direction close to the ground contact piece 120. At the same time, the grounding terminal 330 is reliably positioned to contact the ground contact piece 120, and the signal terminal 320 is reliably positioned to contact the signal contact piece 110, thereby improving the reliable assembly and limiting of the grounding conductive covering 340a and the insulating covering component 340b. See also Figure 13Furthermore, the inner wall of the grounding conductive covering body 342 is provided with two oppositely arranged second gear flanges 3424, and two positioning grooves 343 are respectively provided on the side walls of the insulating covering component 340b. The two second gear flanges 3424 are both inserted into the two positioning grooves 343. Under the joint blocking and limiting action of the first gear flange 3422 and the second gear flange 3424, the problem of separation between the insulating covering component 340b and the grounding conductive covering body 342 is better avoided. At the same time, the grounding terminal 330 is more reliably positioned to contact the grounding contact piece 120, and the signal terminal 320 is more reliably positioned to contact the signal contact piece 110, thereby improving the more reliable assembly and limiting of the grounding conductive covering component 340a and the insulating covering component 340b.
[0056] like Figure 11 and Figure 12 As shown, the grounding conductive cover body 342 further includes a connected insertion stopper 342a and an inclined portion 342b. Both the insertion stopper 342a and the inclined portion 342b are coated on the surface of the insulating cover assembly 340b. The bent fixing portion 344 is connected to the inclined portion 342b. The insertion stopper 342a is inserted into the compression slot 202, allowing the grounding conductive cover body 342 to be inserted into the compression slot 202 while reducing the space occupied by the cable assembly 10. The first stopper flange 3422 and the second stopper flange 3424 are both located within the inclined portion 342b. In this embodiment, the insertion stopper 342a extends parallel to the plane of the conductive base 200, while the inclined portion 342b extends at an angle to the insertion stopper 342a. This ensures that the insertion stopper 342a is securely inserted into the compression slot 202, providing a good retaining function. In this embodiment, the angle can be 20° to 60°. Specifically, the angle is 30°, so that the insertion limit portion 342a can be reliably inserted into the compression slot 202, playing a better limiting role and making the structure of the cable assembly more compact.
[0057] like Figure 12 and Figure 13As shown, in one embodiment, the number of signal terminals 320 and ground terminals 330 of each conductive cable is two. There are two signal contact pieces 110 corresponding to the two signal terminals 320 of each conductive cable. The two signal terminals 320 are respectively in one-to-one contact with the two signal lines 312, and the two signal terminals 320 are respectively in contact with the corresponding signal contact pieces 110, so as to realize differential signal transmission of each conductive cable. The ground terminal 330 of each conductive cable includes a ground terminal body 330a and two grounding contact portions 330b, and the two grounding contact portions 330b are both connected to the ground terminal body 330a. The ground terminal body 330a is in contact with the conductive copper foil 316, so that the ground terminal 330 is in contact with the conductive copper foil 316. See also Figure 5 There are two ground contact pieces 120, and the two grounding abutting portions 330b abut against the two ground contact pieces 120, respectively, to better ground the ground terminal 330 of each conductive cable. In this embodiment, the two signal contact pieces 110 are located between the two ground contact pieces 120, and the two signal contact pieces 110 and the two ground contact pieces 120 are arranged side by side.
[0058] like Figure 10 、 Figure 12 and Figure 13 As shown, in one embodiment, the grounding terminal 330 is partially exposed on the surface of the insulating cover assembly 340b, and the grounding conductive cover 340a abuts and presses against the grounding terminal 330. Because the grounding conductive cover 340a covers the surface of the insulating cover assembly 340b, the grounding conductive cover 340a and the grounding terminal 330 are reliably electrically connected to each other. Moreover, because the grounding conductive cover 340a is inserted into the pressing slot 202, the grounding conductive cover 340a and the conductive base 200 are in contact and electrically connected. This allows the conductive base 200 and the conductive copper foil 316 to be reliably connected to the ground contact piece 120 through the grounding terminal 330, thereby achieving reliable signal transmission for each conductive cable 300. In this embodiment, the grounding conductive cover body 342 abuts and presses against the grounding terminal 330, causing the grounding conductive cover 340a to abut and press against the grounding terminal 330.
[0059] like Figure 6 、 Figure 8 and Figure 10As shown, in one embodiment, the ground terminal body 330a is further encased in the insulating protective sleeve 318, and the conductive copper foil 316 partially exposed outside the insulating protective sleeve 318 abuts against the ground terminal body 330a, thereby securely securing the ground terminal body 330a to the insulating protective sleeve 318 and reliably abutting the ground terminal body 330a and the conductive copper foil 316. In this embodiment, the ground terminal body 330a is exposed on the surface of the insulating cover assembly 340b, and the grounding conductive cover body 342 abuts and presses against the ground terminal body 330a, thereby abutting and pressing the grounding conductive cover body 342 against the ground terminal 330.
[0060] like Figure 10 As shown, in one embodiment, the ground terminal body 330a is formed with a contact protrusion 3303, which protrudes toward the side close to the conductive copper foil 316 and contacts the surface of the conductive copper foil 316, so that the ground terminal 330 can better contact the conductive copper foil 316. Figure 9 As shown, the ground terminal body 330a further includes an elastic portion 3304. The elastic portion 3304 is bent and abuts against the conductive copper foil 316. The elastic portion 3304 and the first elastic portion are located on either side of the conductive copper foil 316. In this embodiment, the bending direction of the elastic portion 3304 is opposite to the protruding direction of the abutting protrusion 3303, so that the elastic portion 3304 and the abutting protrusion 3303 elastically abut against opposite sides of the conductive copper foil 316, thereby reliably conductively connecting the conductive copper foil 316 to the ground.
[0061] like Figure 6 As shown, in one embodiment, the grounded conductive covering member 340a is formed with a first limiting opening 3402, and the insulating covering assembly 340b is partially located within the first limiting opening 3402, thereby securely connecting and positioning the insulating covering assembly 340b with the grounded conductive covering member 340a. Furthermore, the grounded conductive covering member 340a is formed with a second limiting opening 3404, and the insulating covering assembly 340b is also partially located within the second limiting opening 3404, thereby securely connecting and positioning the insulating covering assembly 340b with the grounded conductive covering member 340a.
[0062] In order to firmly connect the signal terminal 320 with the signal line 312 and to reliably connect the signal terminal 320 with the signal line 312, Figure 9 and Figure 10 As shown, in one embodiment, the signal terminal 320 and the signal line 312 are fixed by welding at their abutting points, so that the signal terminal 320 and the signal line 312 are firmly connected and the signal terminal 320 and the signal line 312 are reliably electrically connected.
[0063] like Figure 12 As shown, in one embodiment, the insulating covering assembly 340b includes a first insulating covering member 3401 and a second insulating covering member 3403. The first insulating covering member 3401 is molded over the abutment area between the ground terminal 330 and the conductive copper foil 316, and the abutment area between the signal terminal 320 and the signal line 312. The abutment areas between the ground terminal 330 and the conductive copper foil 316, and the abutment areas between the signal terminal 320 and the signal line 312, are both molded and fixed by the insulating covering assembly 340b. Portions of the ground terminal 330 and the signal terminal 320 are exposed outside the first insulating covering member 3401. The second insulating covering 3403 is overmolded onto the first insulating covering 3401 and the portion of the ground terminal 330 exposed within the first insulating covering 3401. This allows both the ground terminal 330 and the first insulating covering 3401 to be securely encased and fixed to the second insulating covering 3403. The ground terminal 330 extends beyond the second insulating covering 3403, ensuring that the ground terminal 330 and the conductive copper foil 316, as well as the signal terminal 320 and the signal line 312, are securely overmolded and fixed by the insulating covering 340b. In this embodiment, the insulating covering 340b is formed using a two-step injection molding process, where the first insulating covering 3401 and the second insulating covering 3403 are overmolded separately. This allows the insulating covering 340b to securely overmold the ground terminal 330 and the conductive copper foil 316, as well as the signal terminal 320 and the signal line 312. It can be understood that the first insulating covering 3401 and the second insulating covering 3403 can both be plastic, so that the insulating covering component 340b can reliably fix the abutment between the ground terminal 330 and the conductive copper foil 316, and the abutment between the signal terminal 320 and the signal line 312 through the insulating covering component 340b, and at the same time, the insulating covering component 340b has better insulation performance.
[0064] It is understood that in other embodiments, the insulating sheath component 340b is not limited to being formed by a two-shot injection molding process. For example, in one embodiment, the insulating sheath component 340b can also be formed by a one-shot injection molding process.
[0065] like Figure 4 As shown, in one embodiment, the grounding conductive covering member 340a is formed with a positioning groove 3405. The conductive cable 300 further includes an insulating separator 350, which is located in the positioning groove 3405 and connected to the grounding conductive covering member 340a. Figure 7The insulating separator 350 defines a first limiting groove 352 and a second limiting groove 354. A portion of the signal terminal 320 is positioned within the first limiting groove 352 and connected to the insulating separator 350, while a portion of the ground terminal 330 is positioned within the second limiting groove 354 and connected to the insulating separator 350. This ensures that the signal terminal 320 and the ground terminal 330 are reliably separated and electrically contact with the corresponding signal contact piece 110 and ground contact piece 120, respectively. In this embodiment, the portion of the signal terminal 320 exposed outside the insulating cover assembly 340b is positioned within the first limiting groove 352 and connected to the insulating separator 350, while the portion of the ground terminal 330 exposed outside the insulating cover assembly 340b is positioned within the second limiting groove 354 and connected to the insulating separator 350. In this embodiment, the insulating separator 350 is made of plastic, which provides it with good insulation performance.
[0066] like Figures 2 to 4 As shown, in one embodiment, the outer wall of the insulating partition 350 is provided with a snap-fit step 356, and the grounding conductive covering 340a is provided with a snap-fit slot 3407 connected to the positioning slot 3405. The insulating partition 350 is located in the positioning slot 3405, and the snap-fit step 356 is snap-fitted with the snap-fit slot 3407, so that the insulating partition 350 is firmly connected to the grounding conductive covering 340a, thereby reliably connecting the insulating partition 350 to the grounding conductive covering 340a.
[0067] In order to ensure that the signal terminals 320 exposed outside the insulating cover component 340b are reliably fixed and positioned on the insulating partition 350 and reliably contact the signal contact piece 110, as shown in FIG. Figure 4 、 Figure 6 and Figure 7 As shown, the portion of the signal terminal 320 exposed outside the insulating cover assembly 340b located within the first limiting groove 352 is bent, so that the signal terminal 320 exposed outside the insulating cover assembly 340b is securely fixed and positioned on the insulating separator 350 and reliably contacts the signal contact piece 110. To ensure that the ground terminal 330 exposed outside the insulating cover assembly 340b is securely fixed and positioned on the insulating separator 350 and reliably contacts the ground contact piece 120, the portion of the ground terminal 330 exposed outside the insulating cover assembly 340b located within the second limiting groove 354 is bent, so that the ground terminal 330 exposed outside the insulating cover assembly 340b is securely fixed and positioned on the insulating separator 350 and reliably contacts the ground contact piece 120.
[0068] like Figure 2 and Figure 5As shown, in one embodiment, the cable assembly 10 further includes a snap plate 400. The conductive base 200 further defines a snap groove 204. The snap plate 400 snaps into the snap groove 204 and presses against the surface of the insulating cover shielding assembly 340, thereby better pressing and restraining the insulating cover shielding assembly 340 on the conductive base 200, thereby better assembling the insulating cover shielding assembly 340 on the conductive base 200. In this embodiment, there are two snap grooves 204, and the snap plate 400 snaps into each of the two snap grooves 204. Specifically, the clamping plate 400 includes a clamping plate body 410 and two plug pins 420. The two plug pins 420 are connected to the clamping plate body 410. The two plug pins 420 are respectively inserted into the two clamping grooves 204, and the clamping plate body 410 is pressed against the surface of the insulating covering shielding assembly 340, so that the insulating covering shielding assembly 340 can be better pressed and limited on the conductive seat 200.
[0069] like Figure 2 、 Figure 5 and Figure 5a As shown, the clamping plate 400 is further provided with at least one separator 430. The separator 430 is used to separate two adjacent conductive cables 300, thereby allowing the two adjacent conductive cables 300 to be securely inserted into the corresponding compression slots 202. At the same time, the clamping plate 400 can simultaneously compress and secure the two conductive cables 300 to the conductive base 200. In this embodiment, the separator 430 is provided on the clamping plate body 410. The clamping plate 400 simultaneously compresses and secures N conductive cables located in the same row to the conductive base 200, where N is an integer greater than or equal to 2. The number of separators 430 is N-1, so that two adjacent conductive cables 300 are separated by one separator 430. In one embodiment, the conductive base 200 defines an insertion slot 206 between two adjacent conductive cables 300. The two adjacent conductive cables 300 are inserted into the corresponding insertion slot 206 via a separator 430, thereby reliably separating the two adjacent conductive cables 300 through the separator 430 and securely securing the clamping plate 400 to the conductive base 200. To ensure reliable grounding of the grounded conductive covering 342 of each conductive cable 300, the clamping plate 400 is a metal plate, allowing it to abut against each conductive cable 300. This prevents the problem of grounding failure of the grounded conductive covering 342 of some conductive cables 300, which could affect reliable signal transmission.
[0070] like Figure 1 and Figure 3As shown, in one embodiment, the conductive base 200 is fixedly connected to the substrate 100, so that the conductive base 200 is reliably connected to the substrate 100. In order to make the conductive base 200 reliably fixedly connected to the substrate 100, further, the conductive base 200 is welded to the substrate 100, so that the conductive base 200 is reliably fixedly connected to the substrate 100. It can be understood that in other embodiments, the conductive base 200 is not limited to being welded to the substrate 100. For example, the conductive base is fixed to the substrate by bolts. Specifically, the conductive base is provided with a fixing hole, and the substrate is provided with a threaded hole. The bolts are respectively located in the fixing hole and the threaded hole, so that the conductive base is fixed to the substrate.
[0071] Compared with the prior art, the present invention has at least the following advantages:
[0072] 1) The above-mentioned conductive cable 300 achieves signal transmission because the signal terminal 320 abuts against the signal line 312 exposed on the periphery of the cable sheath 314; and achieves reliable grounding return because the ground terminal 330 abuts against the conductive copper foil 316. Since the insulating sheathing shielding assembly 340 is respectively coated at least at the abutment area between the ground terminal 330 and the conductive copper foil 316 and the abutment area between the signal terminal 320 and the signal line 312, the ground terminal 330 and the conductive copper foil 316, and the signal terminal 320 and the signal line 312 can all be reliably abutted and positioned. Moreover, since portions of the signal terminal 320 and the ground terminal 330 are both exposed on the insulating sheathing shielding assembly 340, The portion of the signal terminal 320 exposed from the insulating covering shielding assembly 340 elastically abuts against the signal contact piece 110 of the substrate 100, and the portion of the ground terminal 330 exposed from the insulating covering shielding assembly 340 elastically abuts against the ground contact piece 120 of the substrate 100. The insulating covering shielding assembly 340 is inserted into the compression slot 202 of the conductive base 200, so that the signal terminal 320 reliably elastically abuts against the signal contact piece 110 of the substrate 100, and the ground terminal 330 reliably elastically abuts against the ground contact piece 120 of the substrate 100. At the same time, the insulating covering shielding assembly 340 elastically abuts against the conductive base 200, thereby achieving reliable grounding and signal transmission of the conductive cable 300.
[0073] 2) Since the abutment between the ground terminal 330 and the conductive copper foil 316, and the abutment between the signal terminal 320 and the signal line 312 are all fixed by plastic wrapping of the insulating shielding assembly 340, the overall structure of the conductive cable 300 is more compact and can be independently disassembled, assembled and replaced. Compared with the traditional cable assembly 10, the cable assembly 10 of the present application is smaller in size.
[0074] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
