Description

Technical Field

[0001] This disclosure relates to the technical field of electronic connectors, and in particular to a plug connector. Background Technology

[0002] In modern electronic systems, cable assemblies are critical components for signal transmission between devices. To suppress electromagnetic interference and radio frequency interference, cables typically employ shielding structures, such as braided shielding mesh, anti-wave sleeves, or conductive cloth, to reduce interference from external electromagnetic fields and prevent internal signals from radiating outwards. However, the termination method of the shielding directly affects its shielding effectiveness and reliability.

[0003] Currently, the termination of the shielding body and the connector shell mainly adopts traditional processes such as external binding, wrapping, or welding. Although these methods are simple, they have obvious drawbacks: binding or wrapping may cause the shielding layer to loosen or even fall off, reducing long-term reliability; welding may damage the cable or connector due to thermal stress, and it is difficult to ensure process consistency. In addition, it is prone to failure in complex vibration or bending environments, resulting in a decrease in shielding performance. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a plug connector with reliable connection and good shielding effect.

[0005] The purpose of this disclosure is achieved through the following technical solution: A plug connector comprising: A connector, the connector comprising a plug and a connecting end that are connected to each other; A straight cable end cover includes a straight outer shell, a mounting plate, and a support frame.

One end of the straight outer shell has a receiving cavity, and the other end of the straight outer shell has a mounting groove that communicates with the receiving cavity. The mounting plate is installed in the opening of the mounting groove and is detachably connected to the straight outer shell. The support frame is installed in the mounting groove and supports the mounting plate. The cable passes sequentially through the cavity of the support frame and the receiving cavity; A shielding body is fitted over the cable and is also folded over and wrapped around the support frame.

[0006] In one embodiment, the plug connector further includes a locking member, a flange is formed around the periphery of the connecting end, the locking member passes through the flange, and the end of the locking member away from the straight cable tail cover is inserted into a corresponding insertion hole on the mating end.

[0007] In one embodiment, the straight cable tail cover further includes a connector, the side wall of the mounting groove is provided with a through hole, the mounting plate is provided with a corresponding connection hole, and the connector passes through the through hole and connects to the connection hole, so that the mounting plate and the straight housing can be detachably connected.

[0008] In one embodiment, mounting blocks are formed on both sides of the mounting plate, the connecting holes are located at both ends of the two mounting blocks, a first groove is formed between the mounting blocks, and one end of the support frame is located in the first groove.

[0009] In one embodiment, the inner wall of the mounting groove is provided with a second groove, which communicates with the first groove, and the periphery of the support frame is respectively engaged in the second groove and the first groove.

[0010] In one embodiment, the straight housing is provided with anti-slip grooves located on the outer surface of the straight housing perpendicular to the direction in which the cable is inserted or removed.

[0011] In one embodiment, the connector and the straight cable end cover are connected by an interference fit, and a curing adhesive layer is provided between the connector and the straight cable end cover. The cable is fixed between the connector and the straight cable end cover by the curing adhesive layer.

[0015] Compared with the prior art, this disclosure has at least the following advantages: The aforementioned plug connector fixes one end of the shielding body inside the straight cable tail cover via a support frame, thereby securing the shielding body to the plug connector and improving the reliability of the connection between the shielding body and the plug connector, preventing the shielding body from loosening or even falling off.

[0016] The shielding body is fitted over the cable and fixed inside the straight cable end cover, completely enclosing the perimeter of both the shielding body and the straight cable end cover. This ensures both effective shielding and cable protection. During assembly, the shielding body and support frame are first installed inside the straight housing, and then the mounting plate is connected to the housing.

[0023] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: Please see Figures 1 to 5 This is a plug connector 10 according to an embodiment of the present invention, which includes a plug 100, a straight cable end cover 200, a cable 300, and a shield 400. The plug 100 includes a plug 110 and a connecting end 120 connected to each other. The straight cable end cover 200 includes a straight outer shell 210, a mounting plate 220, and a support frame 230. The straight outer shell 210 is installed at the end of the connecting end 120 away from the plug 110. One end of the straight outer shell 210 has a receiving cavity 201, and the other end of the straight outer shell 210 forms a mounting groove 202, which communicates with the receiving cavity 201. The mounting plate 220 is installed in the groove of the mounting groove 202 and is detachably connected to the straight outer shell 210. The support frame 230 is installed in the mounting groove 202 and supports the mounting plate 220. The cable 300 passes sequentially through the cavity of the support frame 2300 and the receiving cavity 201. The shield 400 is fitted onto the cable 300, and the shield 400 is also folded over and wrapped around the support frame 230.

[0024] In this embodiment, the plug connector 10 is fixedly connected to the plug connector 10 by fixing one end of the shield 400 inside the straight cable end cover 200 via the support frame 230. This improves the reliability of the connection between the shield 400 and the plug connector 10 and prevents the shield 400 from loosening or even falling off. Furthermore, the shield 400 is fitted over the cable 300 and fixed inside the straight cable end cover 200, completely covering the periphery of both the shield 400 and the straight cable end cover 200, ensuring both shielding effectiveness and protection for the cable 300. Simultaneously, during assembly, the shield 400 and support frame 230 are first installed in the straight housing 210, and then the mounting plate 220 is connected to the straight housing 210. This facilitates the installation of the shield 400 and mounting plate 220, preventing the shield 400 and support frame 230 from shifting due to compression during assembly. This ensures the accuracy and stability of the installation of the shield 400 and support frame 230, thereby ensuring the shielding effect and connection reliability of the plug connector 10. Furthermore, the plug connector 10 is fixed inside the straight cable tail cover 200 by the support frame 230, which is simple in structure, simplifies assembly, and avoids damage to the cable 300 or the plug connector 10 during the connection and assembly process.

[0025] like Figure 1 As shown, in one embodiment, the plug connector 10 further includes a locking member 500. A flange portion 121 is formed on the periphery of the connecting end 120. The locking member 500 passes through the flange portion 121, and the end of the locking member 500 away from the straight cable tail cover 200 is inserted into the corresponding insertion hole of the mating end. Specifically, in this embodiment, flange portions 121 are formed on both sides of the connecting end 120. Both flange portions 121 have through holes (not shown). The locking member 500 is a screw. The screw passes through the through holes and is inserted into the flange portion 121. The head of the screw is located on the side of the flange portion 121 away from the plug 100, and the shank is located on the side of the flange portion 121 facing the plug 110. When the plug connector 10 is plugged in, the screw is inserted into the corresponding insertion hole of the mating end and tightened by the screw head, so that the plug connector 10 is firmly connected to the mating end, preventing the plug connector 10 from loosening or even coming off during use, and improving the connection stability of the plug connector 10. This design ensures a secure connection between the plug connector 10 and the mating end, while facilitating installation and removal, making it particularly suitable for applications in vibrating environments or those requiring frequent plugging and unplugging.

[0026] It should be noted that the mating end includes, but is not limited to, female connectors for industrial equipment, interfaces for automotive electronic devices, and connectors for military and aerospace equipment.

[0027] like Figures 1 to 4As shown, in one embodiment, the straight cable end cover 200 further includes a connector 600. A through hole 2021 is provided on the side wall of the mounting groove 202, and a corresponding connection hole 2201 is provided on the mounting plate 220. The connector 600 passes through the through hole 2021 and connects to the connection hole 2201, allowing the mounting plate 220 to be detachably connected to the straight housing 210. It can be understood that by the connector 600 passing through the through hole 2021 and engaging with the connection hole 2201, the mounting plate 220 and the straight housing 210 are aligned and connected, improving the overall structural stability and vibration resistance, dispersing stress, and preventing loosening. Simultaneously, it maintains the continuity of the shielding structure, ensuring the shielding effect of the plug connector 10. Further, in this embodiment, the connector 600 is a screw.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment, mounting blocks 221 are formed on both sides of the mounting plate 220, connecting holes 2201 are located at both ends of the mounting blocks 221, a first groove 2202 is formed between the mounting blocks 221, and one end of the support frame 230 is disposed in the first groove 2202.

[0029] like Figures 1 to 4 As shown, in one embodiment, the inner wall of the mounting groove 202 is provided with a second groove 2022, which communicates with the first groove 2202. The periphery of the support frame 230 is respectively engaged in the second groove 2022 and the first groove 2202. Specifically, in this embodiment, the first groove 2202 and the second mounting groove 2022 communicate to form a support frame mounting groove 202, so that the support frame 230 is fixedly installed in the support mounting groove 202, avoiding displacement or slippage during assembly, reducing assembly difficulty, and enhancing structural stability and connection strength. In addition, mounting blocks 221 are provided on both sides of the mounting plate 220 to improve the vibration resistance and structural stability of the plug connector 10 and avoid deformation caused by stress concentration.

[0030] like Figures 1 to 3 As shown, in one embodiment, the straight housing 210 is provided with an anti-slip groove 2101, which is located on the outer surface of the straight housing 210 perpendicular to the extension direction of the plug-in cable 300. It is understood that by providing the anti-slip groove 2101 on the plug-in grip surface, friction is increased, preventing slippage during plugging and unplugging. Further, in this embodiment, there are two anti-slip grooves 2101, which are arranged opposite to each other.

[0031] like Figure 2As shown, in one embodiment, the plug 100 and the straight cable end cover 200 are connected by an interference fit. A curing adhesive layer 130 is provided between the plug 100 and the straight cable end cover 200, and the cable 300 is fixedly disposed between the plug 100 and the straight cable end cover 200 by the curing adhesive layer 130. Specifically, in this embodiment, the plug 100 and the straight cable end cover 200 are installed by an interference fit and fixed by potting adhesive. The potted adhesive forms a curing adhesive layer 130 between the plug 100 and the straight cable end cover 200. At the same time, the cable 300 is fixed inside the plug connector 10, fixing its position and size. In this way, the vibration resistance and impact resistance of the plug connector 10 can be improved.

[0032] like Figure 2 As shown, in one embodiment, the shield 400 includes a nylon sheath 410 and a wave-damping sleeve 420. The nylon sheath 410 and the wave-damping sleeve 420 are respectively fitted onto the cable 300. The nylon sheath 410 and the wave-damping sleeve 420 are also flipped and wrapped around the support frame 230. Specifically, the nylon sheath 410 and the wave-damping sleeve 420 are fitted onto the tail of the cable 300 and pass through the cavity of the support frame 230. Then, they are folded outwards for a certain length so that the nylon sheath 410 and the wave-damping sleeve 420 wrap around the frame of the support frame. Finally, the support frame 230 presses and fixes the nylon sheath 410 and the wave-damping sleeve 420 into the straight cable tail cover 200, and forms a tight contact with the periphery of the end of the straight cable tail cover 200 away from the plug 100. In this way, the nylon sheath 410 and the anti-wave sheath 420 will not come off backward and will be firmly fixed inside the straight cable tail cover 200 by the support frame 230, which not only ensures the shielding effect but also protects the cable 300.

[0033] It should be noted that in this embodiment, the cable 300, the nylon sheath 410, and the anti-wave sleeve 420 are arranged in sequence.

[0034] like Figure 2 and Figure 5 As shown, in one embodiment, the outer periphery of the support frame 230 is provided with multiple protruding ribs 2301, all of which abut against the inner wall of the mounting groove 202. It is understood that the shield 400 is pressed and fixed within the mounting groove 202 by the support frame 230. The protruding ribs 2301 increase the contact area between the shield 400, the support frame 230, and the mounting groove 202, increasing friction and further enhancing the connection stability of the shield 400.

[0035] like Figure 2As shown, in one embodiment, the plug connector 10 further includes a heat shrink tubing 600, which is fitted over the portion of the shielding body 400 extending beyond the straight housing 210. It is understood that the heat shrink tubing 600 covers the end of the straight cable end cap 200 away from the connector 100 and the exposed cable 300, forming a tight fit through heat shrinking, thereby tightly enclosing the portion of the shielding body 400 extending beyond the straight housing 210, further enhancing the shielding and protection effects of the plug connector 10.

[0036] Compared with the prior art, this disclosure has at least the following advantages: The aforementioned plug connector fixes one end of the shielding body inside the straight cable tail cover via a support frame, thereby securing the shielding body to the plug connector and improving the reliability of the connection between the shielding body and the plug connector, preventing the shielding body from loosening or even falling off.

[0037] The shielding body is fitted over the cable and fixed inside the straight cable end cover, completely enclosing the perimeter of both the shielding body and the straight cable end cover. This ensures both effective shielding and cable protection. During assembly, the shielding body and support frame are first installed inside the straight housing, and then the mounting plate is connected to the housing. This facilitates the installation of the shielding body and mounting plate, preventing misalignment due to compression during assembly. This ensures the accuracy and stability of the shielding body and support frame installation, thereby guaranteeing the shielding effect and connection reliability of the plug connector.

[0038] The plug connector uses a support frame to fix the shield inside the straight cable tail cover. The structure is simple, simplifies assembly, and avoids damage to the cable or plug connector during the connection and assembly process.

[0039] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
