Description

Technical Field

[0001] The utility model relates to a fixing component between an electric connector and a transmission cable, belonging to the technical field of electric signal transmission equipment. Background Art

[0002] As high-speed signal transmission rates increase, the signal integrity requirements for the transmission channels they carry are becoming increasingly stringent. A stable electrical connector structure is a prerequisite for ensuring high-speed electrical signal transmission. However, in actual electrical connector applications, transmission cables are more susceptible to external environmental interference such as vibration, pulling, and heavy lifting. This can cause deformation at the junction of the transmission cable and the plug, affecting the structural stability of the electrical connector and ultimately leading to signal integrity issues.

[0003] Existing electrical connector designs typically focus on signal path design while neglecting the signal return path (ground). However, further improving connector performance lies in optimizing the signal return path. When a high-speed signal enters a transmission cable from a plug, the electrical signal transitions from one structure to another. For example, when a signal enters a transmission cable from a plug, poorly designed signal transitions can easily lead to discontinuous energy flow, limiting the overall electrical performance of the connector.

[0004] For example, existing transmission cable ground wires are directly soldered to the plug without additional processing. Another example is simply ignoring the ground wire structure in the transmission cable, meaning it is not soldered. Another example is simply soldering all ground wires together. While these transition structure treatments are easy to manufacture, they are often limited in their ability to transmit high-frequency signals. Some electrical connectors also incorporate a transition structure between the cable and the plug. While this improves electrical performance, the addition of the auxiliary transition structure requires adjustments to the connector's manufacturing process. Utility Model Content

These terms are only used to distinguish elements of the same type from each other. For example, a first element may also be referred to as a second element, and similarly, a second element may also be referred to as a first element without departing from the scope of the present disclosure.

[0041] See also Figures 1 to 8 The fixing assembly between the electrical connector and the transmission cable of the technical solution of the present invention includes a first fixing member 100 and a second fixing member 200. The first fixing member 100 is connected to the electrical connector 400. The first fixing member 100 is provided with a first contact portion 110. The second fixing member 200 contacts the first fixing member 100. The second fixing member 200 is provided with a second contact portion 210. The first contact portion 110 and the second contact portion 210 respectively contact the two sides of the transmission cable 300.

[0042] In the present invention, a fixing component is provided between the electrical connector 400 and the transmission cable 300. The first contact portion 110 and the second contact portion 210 cooperate to clamp the transmission cable 300, thereby fixing the structure of the connection between the transmission cable 300 and the electrical connector 400 so that it is not easily deformed. This provides a good transition structure for high-speed signals to enter the transmission cable 300 from the plug, thereby improving the continuity of signal transmission and the electrical performance of the electrical connector 400.

[0043] See also Figures 1 to 8, the plug assembly in the electrical connector 400 is connected to the transmission cable 300, and the socket assembly is connected to the circuit board 500. The plug assembly is inserted into the socket assembly so that the transmission cable 300 is connected to the circuit board 500 to realize signal transmission. Among them, the plug assembly includes a plug partition 420, a plug connecting plate 430, a plug housing and a conductive part. The plug partition 420 and the plug connecting plate 430 are connected to form a space for accommodating the conductive part. The two ends of the conductive part are respectively connected to the transmission cable 300 and the circuit board 500. Specifically, one side of a plurality of plug partitions 420 is connected to the plug connecting plate 430 and placed in the plug housing, thereby forming an independent space. The conductive part is placed in the independent space, and the transmission cable 300 enters the independent space from the side of the plug assembly away from the socket assembly to connect with the conductive part. For further reference, see Figure 1 , multiple transmission cables 300 are arranged in two rows, respectively arranged on the front and rear sides of the electrical connector 400. Correspondingly, two groups of multiple plug partitions 420 are provided, and two plug connecting plates 430 are respectively connected to the inner sides of the two groups of plug partitions 420, thereby forming two groups of independent spaces for accommodating multiple conductive parts.

[0044] In some embodiments, after the transmission cable 300 is inserted into the electrical connector 400, it is fixed by a fixing assembly so that the connection structure between the transmission cable 300 and the electrical connector 400 is not easily deformed. Figure 1 When the plug assembly is positioned above the receptacle assembly, the transmission cable 300 is inserted from the upper side of the plug assembly, and the fixing assembly is positioned above the plug assembly and clamps the transmission cable 300. Specifically, the signal line at the end of the transmission cable 300 is stripped and inserted into the electrical connector 400. The signal line contacts and connects with the conductive member. The two sides of the outer wall of the transmission cable 300 above the signal line contact the first contact portion 110 and the second contact portion 210, respectively, thereby securing the transmission cable 300 and preventing deformation at the connection between the electrical connector 400 and the transmission cable 300. Furthermore, the fixing assembly can contact the outermost insulating medium of the transmission cable 300. Furthermore, the fixing assembly can also contact the ground structure 310, such as the shielding layer and ground wire of the transmission cable 300, thereby grounding the fixing assembly.

[0045] In some embodiments, the shape of the first contact portion 110 and / or the second contact portion 210 matches the shape of the transmission cable 300. That is, based on the structure of the contact portion of the transmission cable 300, the shape of the first contact portion 110 and / or the second contact portion 210 is configured as a contoured bent structure that matches the structure of the transmission cable 300. This allows the first contact portion 110 and / or the second contact portion 210 to form a close contact with the transmission cable 300, increasing the contact area between the two and thereby improving the effectiveness of the fixing assembly in securing the transmission cable 300. Specifically, the outer side of the transmission cable 300 is a first curved surface, and correspondingly, the first contact portion 110 and the second contact portion 210 are both provided with a second curved surface with a matching curvature. These first and second curved surfaces are in close contact with each other to secure the transmission cable 300.

[0046] Furthermore, the first contact portion 110 and the second contact portion 210 have the same structure and are symmetrically arranged on opposite sides of the transmission cable 300. This ensures that the force on both sides of the transmission cable 300 is evenly distributed, and the transmission cable 300 is less likely to shift at the connection point. It is understood that one, two, or more first contact portions 110 and second contact portions 210 may be provided. Furthermore, both the first contact portion 110 and the second contact portion 210 may be provided to the same number as the number of transmission cables 300, with each transmission cable 300 having one first contact portion 110 and one second contact portion 210 on both sides.

[0047] In some embodiments, the first contact portion 110 protrudes toward the outside of the first fixing member 100, and the second contact portion 210 protrudes toward the outside of the second fixing member 200. Figure 1 and Figure 2 The first fixing member 100 is arranged above the plug assembly, the first contact portion 110 protrudes above the first fixing member 100, the second fixing frame is arranged above the plug assembly, and the second contact portion 210 protrudes above the second fixing member 200.

[0048] In some embodiments, see Figure 2 and Figure 3 The first fixing member 100 is provided with a plurality of first contact portions 110. The two groups of transmission cables 300 are arranged side by side. Accordingly, the plurality of first contact portions 110 are divided into two groups. The two groups of first contact portions 110 are located in the middle of the first fixing member 100 and the second arc surface openings of the two groups are opposite, that is, the second arc surface openings of the two groups of first contact portions 110 are both facing outward. Furthermore, the two groups of first contact portions 110 are symmetrically arranged. There are two second fixing members 200, which are arranged on both sides of the first fixing member 100. The positions of the second contact portions 210 on both sides of the first fixing member 100 correspond to the positions of the first contact portions 110, and the second arc surface openings of the second contact portions 210 are both facing inward. See. Figure 3 and Figure 4The first fixing member 100 is located between the two groups of transmission cables 300, and the two groups of first contact portions 110 are in contact with the inner sides of the transmission cables 300 respectively. The two second fixing members 200 are respectively located on both sides of the first fixing member 100, and the second contact portions 210 on the two second fixing members 200 are in contact with the outer sides of the two groups of transmission cables 300 respectively.

[0049] In some embodiments, see Figure 5 The electrical connector 400 includes a housing 410, such as a plug housing, and a fixing assembly is disposed within the housing 410. The second fixing member 200 includes a second fixing portion 230 and a second abutting portion 220. The second contact portion 210 is disposed on the second fixing portion 230. The second fixing portion 230 is connected to the second abutting portion 220. The second abutting portion 220 abuts against the first fixing member 100 and the housing 410, respectively, to achieve a stress fit between the first fixing member 100, the second fixing member 200, and the housing 410, thereby allowing the fixing assembly to be tightly assembled on the plug assembly.

[0050] In some embodiments, see Figures 2 to 5 The second fixing portion 230 is provided with a connecting block 231 and a connecting plate 232. The inner side of the connecting block 231 is connected to the second contact portion 210, and the outer side of the connecting block 231 is connected to the upper side of the connecting plate 232. The connecting plate 232 is a long strip. The connecting plate 232 is arranged vertically. The end of the connecting plate 232 is connected to the second abutting portion 220. The middle part of a connecting plate 232 is connected to multiple second contact portions 210 and multiple connecting blocks 231. Each second contact portion 210 is arranged on the upper side of the connecting plate 232 through a connecting block 231. The second arc surface opening of the second contact portion 210 faces away from the connecting plate 232 and the connecting block 231.

[0051] In some embodiments, the second fixing member 200 is provided with two second abutting portions 220, and the two second abutting portions 220 are provided on opposite sides of the second fixing member 200. Figure 4 and Figure 5 The second abutting portions 220 are provided in a plurality, for example, two, and the two second abutting portions 220 are respectively connected to the ends of the connecting plate 232 of the second fixing portion 230. Specifically, the second abutting portion 220 is provided with an upper abutting plate 221, an intermediate abutting plate 222, and a lower abutting plate 223, which are connected in sequence. The intermediate abutting plate 222 is perpendicular to the upper abutting plate 221 and the lower abutting plate 223. The upper and lower sides of the intermediate abutting plate 222 are respectively connected to the upper abutting plate 221 and the lower abutting plate 223, and the side edges of the intermediate abutting plate 222 are connected to the side surfaces of the connecting plate 232. The upper abutting plate 221 abuts the first fixing member 100, the intermediate abutting plate 222 abuts the housing 410, and the lower abutting plate 223 may also abut other components of the plug assembly.

[0052] In some embodiments, the first fixing member 100 includes a first fixing plate 130 and a first abutting plate 120, the first contact portion 110 is disposed in the middle of the first fixing plate 130, and the first abutting plate 120 is disposed at the end of the first fixing plate 130. Figure 2 and Figure 3 The first fixing plate 130 is in the shape of a long strip, and the plurality of first contact portions 110 are respectively arranged on the front and rear sides of the first fixing plate 130 . Furthermore, the plurality of first contact portions 110 are symmetrically arranged on the front and rear sides of the first fixing plate 130 .

[0053] Furthermore, there are a plurality of first abutting plates 120, for example, two. Figure 2 and Figure 3 The first abutting plate 120 is in the shape of an elongated plate, and two first abutting plates 120 are disposed on the left and right sides of the first fixing plate 130. The left or right side of the first abutting plate 120 is connected to the first fixing plate 130, and the front or rear side of the first abutting plate 120 abuts against the second fixing member 200. It is understood that there may be multiple first abutting plates 120 and multiple second abutting portions 220. The number of first abutting plates 120 may match the number of second abutting portions 220. Multiple first abutting plates 120 may be disposed in the middle and ends of the first fixing plate 130, and some of the first abutting plates 120 may be disposed between the two first contact portions 110. Multiple second abutting portions 220 may be disposed in the middle and ends of the second fixing portion 230, and some of the second abutting portions 220 may be disposed between the two second contact portions 210. It should be noted that the position of the first abutting plate 120 matches the position of the second abutting portion 220 , so that each first abutting plate 120 can contact each second abutting portion 220 .

[0054] Specifically, see Figure 5When the second fixing member 200 is inserted from the side of the first fixing member, the upper abutment plate 221 abuts against the first abutment plate 120, and the upper abutment plate 221 is partially arranged below the first abutment plate 120. When the shell 410 of the plug assembly is put on the fixing assembly, the outer side of the middle abutment plate 222 abuts against the inner side of the shell 410, and the outer side of the connecting plate 232 can also abut against the inner side of the shell 410. Furthermore, the lower side of the lower abutment portion contacts the upper side of other components of the plug assembly. After the fixing assembly of the present invention is set in the plug assembly, the two second fixing members 200 are respectively inserted into the two sides of the first fixing member 100, and the left and right sides of the second fixing member 200 are respectively abutted against the left and right sides of the first fixing member 100, and the first contact portion 110 and the second contact portion 210 are respectively abutted against the opposite sides of the transmission cable 300. Through the stress matching between the first fixing member 100, the second fixing member 200 and the shell 410, the fixing assembly and the transmission cable 300 are tightly assembled in the plug assembly, and the fixing assembly with the contoured bending structure is tightly matched with the transmission cable 300, so that the connection structure of the transmission cable 300 and the plug assembly is not easy to deform, which is conducive to ensuring the transmission continuity of the electrical connector 400.

[0055] In some embodiments, see Figure 2 and Figure 6 The first fixing member 100 is provided with a through slot 140. The electrical connector 400 includes a plate, for example, the electrical connector 400 includes a plug partition 420 and a plug connection plate 430. The plate is inserted into the through slot 140. Specifically, a plug connection plate 430 is connected to the side surfaces of multiple plug partitions 420. The plug connection plate 430 is perpendicular to the plug partitions 420. The first fixing plate 130 is provided with multiple through slots 140. The positions and shapes of the multiple through slots 140 match those of the plug partitions 420 or the plug connection plate 430. Figure 1 and Figure 6 Two plug connection plates 430 are positioned between the two sets of plug partitions 420. The shape of the through slots 140 matches the shape of the plates they pass through. A wider through slot 140 is provided in the middle of the first fixing member 100 to allow both plug connection plates 430 to pass through the wider through slot 140 simultaneously. Multiple narrower through slots 140 are provided on both sides of the first fixing member 100. The narrower through slots 140 are perpendicular to the wider through slots 140, and each narrower through slot 140 allows one plug partition 420 to pass through. Furthermore, the second fixing member 200 is provided with multiple notches 240 that allow the plug partition 420 to pass through. The position and shape of the notches 240 match those of the plug partitions 420, and the outer side of the plug partition 420 can pass through the notches 240. It is understood that the second fixing member 200 and the plug partition 240 can be welded together at the notches 240.

[0056] In some embodiments, the plate and the first fixing member 100 are welded at the through groove 140. Figure 1 The plug partition 420 and the plug connecting plate 430 protrude from the upper side of the first fixing member 100 through the through groove 140, and are stably welded by tin or laser welding, so that the fixing assembly plays a better role in fixing the transmission cable 300.

[0057] Specifically, during the assembly of the electrical connector 400, the first fixing member 100 is first assembled on the plug assembly so that the plug partition 420 and the plug connecting plate 430 protrude from the surface of the first fixing member 100 through the through slot 140 (see FIG. Figure 6 ), optionally welded at the through slot 140, and then the transmission cable 300 is inserted into the plug assembly, and the transmission cable 300 is pressed by the welding head 600 such as the HotBar head (see Figure 7 and Figure 8 ) for welding, at this time, the transmission cable 300 contacts the first contact portion 110 with the contoured structure, and a good stress contact can be generated between the two. After the transmission cable 300 is welded, the second fixing members 200 (see Figure 1 and Figure 8 ), the notch 240 of the second fixing member 200 is fitted with the plug partition 420, and the second contact portion 210 having a contoured structure contacts the transmission cable 300. Under the stress of the second fixing member 200, the first fixing member 100, and the housing 410 of the plug assembly, the second contact portion 210 is in close contact with the transmission cable 300. Furthermore, the shielding layer of the transmission cable 300 contacts the first contact portion 110 and the second contact portion 210. At the same time, the ground structure 310 of the transmission cable 300 is welded to the second fixing member 200 (see Figure 1 ), or the second fixing member 200 is welded together with any one or more components of the plug assembly, such as the plug partition 420, the plug connecting plate 430, etc., so as to fix the second fixing member 200, which can further improve the stability of the transmission cable 300.
