Description

Technical Field

[0001] This application relates to the field of electrical connection device technology, and more particularly to a plug connector. Background Technology

[0002] In plug connectors, multiple cables are connected one-to-one with multiple plug terminals, ensuring that the signal transmitted by each cable is independent and free from interference. This one-to-one connection of multiple cables to multiple plug terminals provides greater scalability and flexibility for electrical control systems. Users can adjust the number of cables and terminals to suit systems of varying sizes and complexities, based on their specific needs. This design enables plug connectors to be widely used in various scenarios, such as industrial control, communication equipment, and automotive electronics.

[0003] In existing technologies, when connecting cables to plug terminals, the core of the cable is usually welded to the connection part of the plug terminal to achieve a conductive connection between the cable and the plug terminal. However, during welding, both the plug terminal and the cable end are in a cantilevered state. In the cantilevered state, the plug terminal and the cable end lack fixed support during welding and are prone to slight displacement due to operational vibration, airflow disturbance or welding thermal stress.

[0004] This minute displacement may cause the solder to fail to fully coat the wire core and terminal surface, resulting in poor soldering (insufficient contact area) or cold soldering (solder not fully fused). This leads to increased contact resistance between the cable and the plug terminal. After long-term use, the current passing through can generate high temperatures, accelerating oxidation or loosening, and ultimately causing problems such as poor contact, signal interruption, or equipment failure. Utility Model Content

[0005] One embodiment of this application provides a plug connector to solve the problem that poor soldering of cables and plug terminals is common in existing plug connectors.

[0006] One embodiment of this application provides a plug connector, including: A metal casing, the metal casing including a first plate; An insulating body, the insulating body including a support part, one side of the support part being attached to the first plate; The plug terminal is fixed in the insulating body, and the connecting part of the plug terminal is attached to the side of the support part facing away from the first plate. A cable, which includes a wire core, one end of which is soldered to a connector; The metal shielding component, the insulating body, and one end of the cable are all sandwiched between the metal shell and the metal shielding component.

[0008] Optionally, the metal shielding component includes a second plate, with the first and second plates respectively covering both sides of the first receiving groove.

[0009] Optionally, the metal shielding has an insulating component on the side facing the wire core, and the insulating component covers the connection area between the connector and the wire core.

[0010] Optionally, the insulating element includes an insulating pad or an insulating coating.

[0011] Optionally, the plug connector also includes a conductive support, on which multiple cables are integrated.

[0012] Optionally, the conductive support is embedded in the insulating body, the insulating body is provided with a first positioning part, and the end of the conductive support is provided with a second positioning part that matches the first positioning part.

[0013] Optionally, the second positioning part includes a step structure, and the first positioning part includes a step surface that matches the step structure.

[0014] Optionally, the first positioning part also includes two limiting surfaces disposed opposite to each other on both sides of the step surface.

[0015] Optionally, a metal shielding element is disposed on the side of the conductive support element facing away from the metal housing, and the metal shielding element is electrically connected to both the conductive support element and the metal housing.

[0016] Optionally, the cable includes a wire core, a first insulation layer, a shielding layer, and a second insulation layer arranged coaxially from the inside to the outside, and the conductive support is integrated with the shielding layer of multiple cables.

[0017] The plug connector provided in this application embodiment has one side of the support portion attached to the first plate, which supports the support portion. The connecting portion of the plug terminal is also attached to the side of the support portion facing away from the first plate, and the supporting portion supports the connecting portion. When welding the connection portion between the cable and the plug terminal, the connecting portion of the plug terminal is supported not only by the support portion of the insulating body but also by the first plate of the metal shell. During welding, this double support structure provides stable support for the connecting portion and the cable core, eliminating the risk of minor displacement of the core and connecting portion during welding. This ensures that the solder fully coats the core and the surface of the connecting portion, preventing poor welding between the cable and the plug terminal, thereby forming a reliable conductive path.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0025] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0026] To address the problem of poor welding between the cable 4 and the plug terminal 3 in existing plug connectors, this application provides a plug connector that not only supports the connecting part 31 of the plug terminal 3 through the support part 21 of the insulating body 2, but also supports the support part 21 through the first plate 11 of the metal shell 1. During the welding process, the double support structure provides stable support for the connecting part 31 and the wire core 41 of the cable 4, eliminating the risk of slight displacement of the wire core 41 and the connecting part 31 during welding, ensuring that the solder fully covers the surface of the wire core 41 and the connecting part 31, avoiding poor welding between the cable 4 and the plug terminal 3, thereby forming a reliable conductive path.

[0027] Please see Figures 1 to 10 This application provides a plug connector, including a metal housing 1, an insulating body 2, plug terminals 3, a cable 4, and a metal shield 5, such as... Figure 1 and Figure 2 As shown.

[0028] The metal housing 1 includes a first plate 11, which is the main body of the metal housing 1. It serves two purposes: firstly, to provide electromagnetic shielding, and secondly, to provide mechanical protection for the internal components of the plug connector. Figure 1 , Figure 2 and Figure 3 As shown.

[0029] The insulating body 2 includes a support portion 21, one side of which is attached to the first plate 11, providing support for the support portion 21. A plug terminal 3 is fixed within the insulating body 2, and the connecting portion 31 of the plug terminal 3 is attached to the side of the support portion 21 facing away from the first plate 11, providing support for the connecting portion 31. The cable 4 includes a wire core 41, one end of which is welded to the connecting portion 31. During the welding process, the support plate and the first plate 11 form a double support structure for the connecting portion 31 and the wire core 41. Figure 5 and Figure 6 As shown, this can prevent the connecting part 31 from being in a suspended state, and at the same time provide stable and reliable support for the end of the wire core 41 in the suspended state, thereby preventing slight displacement between the connecting part 31 and the wire core 41 during the welding process, and ensuring the welding quality between the wire core 41 and the connecting part 31.

[0030] It should be noted that the first plate 11 of the metal shell 1 in this application serves as a rigid support, complementing the support portion 21 of the insulating body 2. Together, they can withstand and disperse welding thermal stress and vibrations and impacts generated by external mechanical forces. Furthermore, the metal shell 1 and the insulating body 2 can be manufactured separately. The plug terminal 3 is first fixed in the insulating body 2, and then the insulating body 2 is embedded in the cavity of the metal shell 1, achieving a tight fit between the connecting portion 31, the support portion 21, and the first plate 11, thus reducing the manufacturing difficulty of the supporting structure of the connecting portion 31.

[0031] Both the insulating body 2 and one end of the cable 4 are sandwiched between the metal shell 1 and the metal shield 5. The cooperation between the metal shell 1 and the metal shield 5 can protect the connection area at the end of the cable 4, preventing moisture, dust and other contaminants from entering the connection area and avoiding the risk of breakage or short circuit at the welding point between the connection part 31 and the wire core 41 due to external factors.

[0032] At the same time, the metal shell 1 and the metal shield 5 cover the connection area between the end of the cable 4 and the connection part 31 of the plug terminal 3, forming a continuous electromagnetic shielding structure, which can effectively block the influence of external electromagnetic interference on the welding area, and at the same time prevent the electromagnetic radiation generated in the welding area from interfering with other circuits.

[0033] In some embodiments of this application, please refer to Figure 2 , Figure 7 and Figure 8 The number of plug terminals 3 and cables 4 are both multiple, which can be used to realize various signal transmissions and avoid signal cross-interference.

[0034] The insulating body 2 has a first receiving groove 22. The support part 21 is a support plate set inside the first receiving groove 22. One end of the cable 4 extends into the first receiving groove 22 and connects to the plug terminal 3. The connecting parts 31 of multiple plug terminals 3 are arranged sequentially along the length direction of the support plate, so that the support plate can synchronously support multiple connecting parts 31. Multiple cables 4 are connected to multiple connecting parts 31 one by one. Since the first receiving groove 22 extends along the arrangement direction of multiple connecting parts 31, it can provide a large operating space for the welding operation of the wire core 41 and the connecting part 31, so that the welding tools (such as soldering irons and laser welding heads) can move freely along the length direction of the first receiving groove 22 without frequent angle adjustment.

[0035] The support portion 21 also extends along the arrangement direction of the multiple connecting portions 31, forming a continuous support surface for the multiple connecting portions 31, and can simultaneously bear the mechanical stress of the multiple connecting portions 31. Compared with traditional split support structures (such as independent slots), it can simplify the manufacturing difficulty of the insulating body 2 while ensuring the support effect.

[0036] In some embodiments of this application, please refer to Figure 4 , Figure 5 and Figure 6 The metal shielding component 5 includes a second plate 51. The first plate 11 and the second plate 51 are respectively covered on both sides of the first receiving groove 22. They can seal both sides of the first receiving groove 22 and form a three-dimensional shielding cavity. While sealing and protecting the wire core 41 and the connecting part 31 inside the first receiving groove 22, they can effectively block the intrusion path of external electromagnetic interference (EMI).

[0037] In some embodiments of this application, please refer to Figure 2 , Figure 5 and Figure 6 An insulating element 6 is provided on the side of the metal shield 5 facing the wire core 41. The insulating element 6 covers the connection area between the connecting part 31 and the wire core 41, and can be used to achieve insulation protection between the metal shield 5 and the wire core 41 and the connecting part 31. It can effectively avoid the risk of short circuit caused by the metal shield 5 accidentally contacting the wire core 41 or the plug terminal 3.

[0038] It should be noted that, since the insulating component 6 can prevent contact between the metal shield 5 and the wire core 41 or the connecting part 31, the cable 4 can be placed as close as possible to the metal shield 5. Figure 5In the height direction shown, the first plate 11, the support 21, the connecting part 31, the wire core 41, the insulating part 6, and the second plate 51 are arranged in sequence. The distance between the second plate 51 of the metal shield 5 and the first plate 11 of the metal shell 1 can be minimized as much as possible, which is conducive to reducing the height of the plug connector, making the structure of the plug connector more compact, and facilitating the miniaturization of the plug connector.

[0039] In some embodiments of this application, please refer to Figure 2 , Figure 5 and Figure 6 The insulating component 6 includes an insulating pad or an insulating coating, which makes the assembly of the insulating component 6 simple. The insulating component 6 can be quickly fixed to one side of the second plate 51 by means of bonding or coating, so as to achieve insulation protection between the metal shield 5, the wire core 41 and the connecting part 31.

[0040] At the same time, the insulating pad or insulating coating can be cut or applied according to the range of the connection area of ​​the wire core 41 and the connecting part 31, so as to achieve a high degree of fit with the connection area of ​​the wire core 41 and the connecting part 31 and avoid waste of insulating materials.

[0041] In some embodiments of this application, please refer to Figure 5 and Figure 6 The insulating component 6 is an insulating adhesive layer coated on one side of the second plate 51, and its thickness can be on the order of millimeters. This is relevant to the thickness of the plug connector (i.e.,...). Figure 5 The height of the connector has a smaller impact, which allows for a more compact structure and facilitates miniaturization of the connector.

[0042] In some embodiments of this application, the plug connector further includes a conductive support 7, on which multiple cables 4 are integratedly disposed. This enables the integrated design of multiple cables 4 and the orderly arrangement of multiple cables 4, which is beneficial to reducing the size of the plug connector.

[0043] Meanwhile, multiple cables 4 are integrated onto the conductive support 7, forming a relatively fixed overall structure that allows for complete assembly without the need for individual cable positioning. This integrated structure also effectively prevents the cables 4 from loosening, falling off, or becoming entangled during use due to external forces, vibrations, or other factors. This ensures the reliability of the electrical connection between the plug connector and the corresponding socket connector, reducing malfunctions and safety hazards caused by connection problems.

[0044] In some embodiments of this application, please refer to Figure 2 , Figure 7 , Figure 8 and Figure 9The conductive support 7 is embedded in the insulating body 2. This embedded design prevents the conductive support 7 from occupying additional space outside the insulating body 2, thus avoiding the additional increase in the size of the plug connector due to the setting of the conductive support 7, which is conducive to achieving a compact setting of the plug connector.

[0045] The insulating body 2 is provided with a first positioning part 23, and the end of the conductive support 7 is provided with a second positioning part 71 that matches the first positioning part 23. During the assembly process, the operator can quickly fit the second positioning part 71 of the conductive support 7 with the first positioning part 23 of the insulating body 2 to achieve rapid positioning. This can significantly shorten the assembly time of the insulating body 2, the conductive support 7, and multiple cables 4, thereby improving overall production efficiency and reducing production costs.

[0046] In some embodiments of this application, please refer to Figure 7 and Figure 8 The first positioning part 23 is a positioning groove communicating with the first receiving groove 22. The ends of multiple cables 4 can smoothly slide into the first receiving groove 22 with the cooperation of the first positioning part 23 and the second positioning part 71, so as to realize the embedded setting of the conductive support 7 and the ends of multiple cables 4 in the insulating body 2. At the same time, the positioning groove can play a certain role in locking and restricting the ends of the conductive support 7, preventing them from shaking, displacing or loosening in the insulating body 2.

[0047] In some embodiments of this application, please refer to Figure 2 , Figure 7 , Figure 8 and Figure 9 The second positioning part 71 includes a step structure 711, and the first positioning part 23 includes a step surface 231 that matches the step structure 711. The step structure 711 and the matching step surface 231 interact to position the conductive support 7 in at least two directions. Specifically, the horizontal surface of the step surface 231 can position and limit the conductive support 7 in the vertical direction, while the vertical surface of the step surface 231 can position and limit the conductive support 7 in the horizontal direction (such as the left and right direction).

[0048] Furthermore, the contact area between the stepped structure 711 and the stepped surface 231 is relatively large. Compared to point contact or line contact, multiple surface contacts can provide more stable support and connection. The larger contact area can disperse the force borne by the end of the conductive support 7, reduce local stress concentration, and thus enhance the load-bearing capacity and stability of the entire structure.

[0049] At the same time, because the step structure 711 and the step surface 231 have unique shape and size characteristics, the assembly can only be completed when the two are correctly aligned during the assembly process. This can prevent the conductive support 7 from having incorrect orientation or positional deviation during assembly, and greatly improve the accuracy and consistency of the assembly.

[0050] In some embodiments of this application, please refer to Figure 7 and Figure 9 The first positioning part 23 also includes two limiting surfaces 232 disposed opposite to each other on both sides of the step surface 231, so that the first positioning part 23 can position the conductive support 7 in at least three directions.

[0051] Specifically, the front and rear sides of the conductive support 7 are provided with mating surfaces 712 for engaging with the limiting surface 232. The limiting surface 232 is used to position and abut against the front and rear sides of the conductive support 7, thereby positioning and limiting the conductive support 7 in the front and rear directions.

[0052] It should be noted that, through the cooperation of the first positioning part 23 and the second positioning part 71, this application can completely realize the assembly and positioning of the conductive support 7 inside the plug connector by only the insulating body 2, without relying on the metal shell 1 or the metal shield 5 to achieve the positioning of the conductive support 7. This eliminates the positioning and assembly operations related to the conductive support 7 and the metal parts, greatly simplifies the assembly process and improves the assembly efficiency.

[0053] In some embodiments of this application, please refer to Figure 2 , Figure 5 and Figure 6 The metal shield 5 is placed on the side of the conductive support 7 facing away from the metal housing 1. The metal shield 5 is electrically connected to both the conductive support 7 and the metal housing 1. On the one hand, the metal shield 5 and the insulating body 2 can be used to fix and limit the conductive support 7. On the other hand, the metal shield 5 can be used to achieve the conductive connection between the conductive support 7 and the metal housing 1, which is conducive to the grounding of the conductive support 7. A multi-directional three-dimensional shielding structure is formed for the connection area of ​​the wire core 41 and the connection part 31.

[0054] In some embodiments of this application, please refer to Figure 3 and Figure 4The metal shell 1 includes a first side baffle 12 and a second side baffle 13 disposed on both sides of the first plate 11. The metal shielding component 5 includes a first flange 52 and a second flange 53 disposed on both sides of the second plate 51. A first welding part 121 is provided on the first side baffle 12, and a second welding part 131 is provided on the second side baffle 13. A high-strength permanent connection between the first flange 52 and the first side baffle 12, and between the second flange 53 and the second side baffle 13 can be achieved by welding. While achieving a conductive connection between the metal shell 1 and the metal shielding component 5, the separation between the metal shielding component 5 and the metal shell 1 is avoided, and the risk of loosening between the metal shell 1 and the metal shielding component 5 can be eliminated or minimized.

[0055] In some embodiments of this application, please refer to Figure 7 The outer periphery of the insulating body 2 is also provided with a protruding rib 26. The protruding rib 26 and the side baffle on the corresponding side form a mechanical clamping of the flange of the metal shield 5, which can limit the displacement of the first flange 52 and the second flange 53 after assembly.

[0056] In some embodiments of this application, please refer to Figure 1 and Figure 4 The metal shield 5 has a third welding part 54, which is correspondingly provided with the conductive support 7. It can be used to realize the fixed connection between the metal shield 5 and the conductive support 7, so that the conductive support 7 and the metal shield 5 can achieve a tighter and more stable conductive contact. In the use of electronic equipment, especially in some situations with many moving parts or harsh working environments, reliable fixing can prevent the metal shield 5 from separating from the conductive support 7 and ensure the integrity of the electromagnetic shielding structure.

[0057] It should be noted that the first welding part 121 and the second welding part 131 can be through holes provided through the side baffle, or grooves that reduce the wall thickness of the welding area. The third welding part 54 can be through holes provided through the second plate 51, or grooves that reduce the wall thickness of the welding area. The first welding part 121, the second welding part 131 and the third welding part 54 can be CNC machined or stamped to provide precise positioning for the corresponding welding operations.

[0058] In some embodiments of this application, please refer to Figure 3 The metal housing 1 also includes a first extension strip 14, a second extension strip 15 and a snap-fit ​​baffle 16 integrally formed with the first plate 11, which can be used to form a snap-fit ​​cavity on the metal housing 1 for snap-fit ​​socket connectors, thereby achieving a stable connection between the plug connector and the socket connector.

[0059] In some embodiments of this application, please refer to Figure 1 , Figure 4 and Figure 7 The insulating body 2 is provided with a third positioning part 24, and the edge of the metal shield 5 is provided with a fourth positioning part 55. Through the cooperation between the third positioning part 24 and the fourth positioning part 55, the accurate assembly and positioning between the insulating body 2 and the metal shield 5 can be quickly realized, preventing the metal shield 5 from shifting relative to the insulating body 2, thereby ensuring that the metal shield 5 plays an efficient shielding role for the multiple plug terminals 3 provided on the insulating body 2.

[0060] Specifically, the third positioning part 24 of the insulating body 2 and the fourth positioning part 55 of the metal shield 5 can form a mechanical interlock through their concave-convex fit, ensuring that the relative position of the metal shield 5 and the insulating body 2 is fixed. Even under high vibration or thermal expansion and contraction environments, the fit between the third positioning part 24 and the fourth positioning part 55 can suppress the displacement of the metal shield 5 and prevent electromagnetic leakage caused by misalignment of the metal shield 5.

[0061] In some embodiments of this application, please refer to Figure 5 and Figure 6 The cable 4 includes a wire core 41, a first insulation layer 42, a shielding layer 43, and a second insulation layer 44 arranged coaxially from the inside to the outside. The wire core 41 can be used to make a conductive connection with the connection part 31 of the plug terminal 3. The first insulation layer 42 is sleeved on the outside of the wire core 41 and can be used to insulate and protect the wire core 41. The shielding layer 43 is sleeved on the outside of the first insulation layer 42 and can reduce electromagnetic interference from the outside to the wire core 41. The second insulation layer 44 is sleeved on the outside of the shielding layer 43 and can be used to protect the shielding layer 43.

[0062] The conductive support 7 is integrated with the shielding layer 43 of the multiple cables 4, enabling conductive contact between the conductive support 7 and the shielding layer 43 of the multiple cables 4. This allows the conductive support 7 to conductively connect the shielding layer 43 of the multiple cables 4 with the metal shielding component 5 and the metal housing 1, forming a continuous and complete electromagnetic shielding system. This system can block external electromagnetic fields from interfering with the signals inside the cables 4, while also suppressing the leakage of electromagnetic radiation generated by the cables 4 themselves, reducing electromagnetic pollution to surrounding electronic equipment. This significantly improves the stability and reliability of the plug connector in complex electromagnetic environments.

[0063] It should be noted that the conductive support 7 is integrated with the shielding layer 43 of multiple cables 4, which reduces the number of connection points between the shielding layers 43 of the cables 4. This not only simplifies the product structure and reduces the complexity of the design, but also reduces the risk of failure caused by loose connections, corrosion and other problems, thereby improving the overall stability and durability of the plug connector.

[0064] Specifically, multiple cables 4 can be stripped of their outer sheaths, exposing part of the shielding layer 43 of the cables 4. Figure 6 As shown; then, the exposed portions of the multiple cables 4 with shielding layers 43 are fixed in the casting mold of the conductive support 7, and molten tin is injected into the interior of the casting mold so that the molten tin wraps the shielding layers 43 of the multiple cables 4. After the molten tin solidifies, the conductive support 7 and the shielding layers 43 of the multiple cables 4 can be integrated.

[0065] In some embodiments of this application, please refer to Figure 5 , Figure 7 and Figure 8 The plug terminal 3 also includes a contact portion 32, which can be used to connect with the socket terminal in the socket connector for data transmission. The insulating body 2 is provided with a second receiving groove 25 for accommodating the contact portion 32, which can protect the contact portion 32.

[0066] Please see Figures 1 to 10 In some embodiments of this application, the assembly process of the above-mentioned plug connector is as follows: Step 1: Position the metal casing 1 accurately; Step 2: Embed the insulating body 2, which is fixed with multiple plug terminals 3, into the cavity of the metal housing 1, so that the support part 21 of the insulating body 2 fits against the first plate 11 of the metal housing 1. Step 3: Assemble the conductive support 7 and multiple cables 4 with the insulating body 2, so that the ends of the wire cores 41 of the multiple cables 4 are correspondingly set with the connection parts 31 of the multiple plug terminals 3; Step 4: Weld the wire core 41 and its corresponding connecting part 31, and provide double support for the welding connection area through the support part 21 and the first plate 11; Step 5: Fix the insulating component 6 to the side of the metal shield 5 facing the wire core 41, and cover the insulating body 2 with the metal shield 5; Step 6: Achieve a fixed conductive connection between the metal shielding component 5, the metal housing 1, and the conductive support component 7 by welding.

[0067] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms.
