Description

[[Technical Field]]

[0001] The present application relates to the technical field of electrical connection devices, and particularly to a plug connector. [[Background Art]]

[0002] In a plug connector, a plurality of cables are connected to a plurality of plug terminals in a one-to-one correspondence, whereby it can be ensured that signals transmitted from each cable are independent and are not interfered. Connecting a plurality of cables to a plurality of plug terminals in one-to-one correspondence provides higher scalability and flexibility to an electrical control system. Users can respond to systems of different scales and complexities by increasing or decreasing the number of cables and terminals according to actual needs. With such a design, plug connectors can be widely applied to various scenarios such as industrial control, communication equipment, and automotive electronics.

[0003] In the prior art, when connecting a cable to a plug terminal, the core wire of the cable is usually welded to the connection portion 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 end portion of the cable are in a cantilever state. In this cantilever state, the plug terminal and the end portion of the cable are not fixedly supported during welding, so slight positional displacement is likely to occur due to vibration during operation, airflow disturbance, thermal stress during welding, and the like.

[0004] Such slight positional displacement may prevent the solder material from sufficiently covering the core wire and the terminal surface, which may lead to poor soldering (insufficient contact area) or cold soldering (the solder material does not completely melt). As a result, the contact resistance between the cable and the plug terminal increases. During long-term use, the flow of current generates high temperature, which promotes oxidation and loosening, and may eventually cause problems such as poor contact, signal interruption, or equipment failure.

[Effects of the Invention]

[0017] In one embodiment of the present invention, the first plate supports the support portion by having one side of the support portion in close contact with the first plate, and the support portion supports the connection portion of the plug terminal by having the opposite side of the support portion from the first plate of the support portion in close contact with the connection portion of the plug terminal. When welding the connection portion between the cable and the plug terminal, support is obtained not only from the support portion of the insulating body to the connection portion of the plug terminal, but also from the first plate of the metal housing to the support portion.

[0019] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following clearly and completely describes the technical solutions of the embodiments of the present application with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0020] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, components and arrangements of specific examples are described below. Of course, they are merely illustrative and are not intended to limit the present application. Furthermore, the present application may repeat reference numerals and / or characters in different examples. This repetition is for the purpose of simplification and clarity, and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0021] For ease of explanation, this specification may use spatial relational terms to describe the relative position or motion of one element or feature shown in a figure to another element or feature. These relational terms include, for example, “inside,” “outside,” “inside,” “outside,” “down,” “downward,” “up,” “above,” “front,” and “back.” Such spatial relational terms are intended to encompass not only the orientation depicted in the drawing but also different orientations of the device during use or operation. For example, if the device in the drawing undergoes a reversal of position, a change in orientation, or a change in motion, these directional indications will change accordingly. For example, an element described as “below the other element or feature” or “below the other element or feature” may subsequently be oriented “above the other element or feature” or “above the other element or feature.” Thus, the exemplary term “below of” may include both up and down orientations. The device may also be oriented in other directions (90-degree rotation or other directions), and the spatial relational descriptions used herein will be interpreted accordingly.

[0022] One embodiment of this application provides a plug connector. This plug connector not only provides support for the connection portion 31 of the plug terminal 3 by the support portion 21 of the insulating body 2, but also provides support for the support portion 21 by the first plate 11 of the metal housing 1. During the welding process, the double support structure stably supports the connection portion 31 and the core wire 41 of the cable 4, eliminating the risk of slight misalignment of the core wire 41 and the connection portion 31 during welding. This ensures that the solder material sufficiently covers the core wire 41 and the surface of the connection portion 31, avoiding the occurrence of solder defects between the cable 4 and the plug terminal 3. This forms a highly reliable conductive path and solves the problem of solder defects between the cable 4 and the plug terminal 3 that are common in conventional plug connectors.

[0023] Referring to Figures 1 to 10, one embodiment of the present application provides a plug connector including a metal housing 1, an insulating body 2, a plug terminal 3, a cable 4, and a metal shielding member 5, as shown in Figures 1 and 2.

[0024] The metal housing 1 includes a first plate 11, which is the main part of the metal housing 1 as shown in Figures 1, 2, and 3, and is used to provide electromagnetic shielding on the one hand and to mechanically protect the internal components of the plug connector on the other hand.

[0025] The insulating body 2 includes a support portion 21, one side of which is in close contact with the first plate 11, allowing the first plate 11 to support the support portion 21. The plug terminal 3 is fixed to the insulating body 2, and the connection portion 31 of the plug terminal 3 is in close contact with the side of the support portion 21 opposite to the first plate 11, allowing the support portion 21 to support the connection portion 31. The cable 4 includes a core wire 41, one end of which is welded to the connection portion 31. During the welding process, as shown in Figures 5 and 6, the support plate and the first plate 11 form a double support structure for the connection portion 31 and the core wire 41. This prevents the connection portion 31 from becoming a cantilever, while simultaneously providing stable and reliable support for the end of the core wire 41 that is in a cantilever state, preventing slight misalignment between the connection portion 31 and the core wire 41 during the welding process, and ensuring the welding quality between the core wire 41 and the connection portion 31.

[0026] Furthermore, the first plate 11 of the metal housing 1 in this application acts as a rigid support, complementing the support portion 21 of the insulating body 2, and can jointly absorb and disperse welding thermal stress and vibrations and shocks caused by external mechanical forces. In addition, the metal housing 1 and the insulating body 2 can be manufactured separately. By first fixing the plug terminal 3 to the insulating body 2, and then embedding the insulating body 2 in the cavity of the metal housing 1, tight contact between the connection portion 31, the support portion 21 and the first plate 11 is achieved, reducing the difficulty of manufacturing the support structure of the connection portion 31.

[0027] Both the insulating body 2 and one end of the cable 4 are sandwiched between the metal housing 1 and the metal shielding member 5. This protects the connection area of ​​the end of the cable 4 through the fitting of the metal housing 1 and the metal shielding member 5, preventing contaminants such as moisture and dust from entering the connection area and avoiding the risk of the weld point between the connection part 31 and the core wire 41 breaking or short-circuiting due to external factors.

[0028] At the same time, the metal housing 1 and the metal shielding member 5 cover the connection area of ​​the connection portion 31 between the cable 4 end and the plug terminal 3, forming a continuous electromagnetic shielding structure, thereby effectively preventing external electromagnetic interference from affecting the welding area and simultaneously preventing electromagnetic radiation generated in the welding area from interfering with other circuits.

[0029] In some embodiments of this application, referring to Figures 2, 7, and 8, the number of plug terminals 3 and cables 4 is multiple, and these are used to enable diverse signal transmission and avoid signal interference.

[0030] The insulating body 2 has a first housing slot 22, and the support part 21 is a support plate provided inside the first housing slot 22. One end of the cable 4 enters the first housing slot 22 and is connected to the plug terminal 3. Multiple connection parts 31 of the plug terminals 3 are arranged sequentially along the length of the support plate, thereby enabling the support plate to synchronously support multiple connection parts 31. Multiple cables 4 are connected to multiple connection parts 31 in a one-to-one correspondence. Because the first housing slot 22 extends along the arrangement direction of the multiple connection parts 31, a large working space is provided for welding operations between the core wire 41 and the connection parts 31, allowing welding tools (e.g., soldering iron, laser welding head) to move freely along the length of the first housing slot 22, eliminating the need for frequent angle adjustments.

[0031] Furthermore, since the support portion 21 is also installed extending along the direction of the arrangement of the multiple connection portions 31, it forms a continuous support surface for the multiple connection portions 31, and can simultaneously support the mechanical stress of the multiple connection portions 31. Compared to conventional segmented support structures (for example, independent locking slots), the manufacturing difficulty of the insulating body 2 can be reduced while ensuring the support effect.

[0032] In some embodiments of this application, referring to Figures 4, 5, and 6, the metal shielding member 5 includes a second plate 51, and the first plate 11 and the second plate 51 are respectively placed on both sides of the first housing slot 22, closing both sides of the first housing slot 22 and forming a three-dimensional shielding cavity, which closes and protects the core wires 41 and connections 31 in the first housing slot 22, while effectively blocking the entry path of external electromagnetic interference (EMI).

[0033] In some embodiments of this application, referring to Figures 2, 5, and 6, an insulating member 6 is provided on the side of the metal shield member 5 facing the core wire 41. The insulating member 6 covers the connection area between the connection part 31 and the core wire 41, providing insulating protection between the metal shield member 5 and the core wire 41 and the connection part 31, and effectively avoiding the risk of a short circuit due to accidental contact between the metal shield member 5 and the core wire 41 or the plug terminal 3.

[0034] Furthermore, since the insulating member 6 can block contact between the metal shield member 5 and the core wire 41 or the connection part 31, the cable 4 can be positioned as close as possible to the metal shield member 5. In the height direction shown in Figure 5, the first plate 11, support part 21, connection part 31, core wire 41, insulating member 6 and second plate 51 are arranged in sequence, and the distance between the second plate 51 of the metal shield member 5 and the first plate 11 of the metal housing 1 is reduced as much as possible. This is advantageous for reducing the height dimension of the plug connector, making the structure of the plug connector more compact and enabling miniaturization of the plug connector.

[0035] In some embodiments of this application, referring to Figures 2, 5, and 6, the insulating member 6 includes an insulating pad or insulating coating, which simplifies the assembly method of the insulating member 6 and allows the insulating member 6 to be quickly fixed in place on one side of the second plate 51 by adhesive or coating, thereby providing insulating protection between the metal shield member 5 and the core wire 41 and connection portion 31.

[0036] Furthermore, the insulating pad or insulating coating can be cut or applied according to the extent of the connection area between the core wire 41 and the connector 31, allowing for a high degree of conformity to the connection area between the core wire 41 and the connector 31, and avoiding waste of insulating material.

[0037] In some embodiments of this application, referring to Figures 5 and 6, the insulating member 6 is an insulating adhesive layer applied to one side of the second plate 51, and its thickness is in millimeters, so as to have little impact on the thickness of the plug connector (i.e., the height in Figure 5), the structure of the plug connector becomes more compact, which is advantageous in achieving miniaturization of the plug connector.

[0038] In some embodiments of this application, the plug connector further includes a conductive support member 7, and a plurality of cables 4 are integrally mounted on the conductive support member 7, thereby enabling an integrated design of the plurality of cables 4 and allowing the plurality of cables 4 to be arranged in an orderly manner, which is advantageous in reducing the volume of the plug connector.

[0039] Furthermore, by integrally installing multiple cables 4 on the conductive support member 7, the multiple cables 4 form a relatively fixed, integrated structure, which enables overall assembly and eliminates the need to attach and position each cable 4 individually. This integrated structure effectively prevents the cables 4 from loosening, falling off, or becoming entangled with each other due to external forces such as pulling or vibration during use, thereby ensuring the reliability of the electrical connection between the plug connector and the corresponding receptacle connector and reducing failures and safety risks caused by connection problems.

[0040] In some embodiments of this application, referring to Figures 2, 7, 8, and 9, the conductive support member 7 is embedded in the insulating body 2. This embedded design prevents the conductive support member 7 from occupying extra space outside the insulating body 2, thus avoiding the installation of the conductive support member 7 unnecessarily increasing the dimensions of the plug connector, which is advantageous for achieving a compact plug connector.

[0041] The insulating body 2 is provided with a first positioning portion 23, and the end of the conductive support member 7 is provided with a second positioning portion 71 that fits with the first positioning portion 23. During assembly, the worker can quickly bring the second positioning portion 71 of the conductive support member 7 into close contact with the first positioning portion 23 of the insulating body 2 to achieve rapid positioning, significantly reducing the assembly time of the insulating body 2, the conductive support member 7 and the multiple cables 4, improving overall production efficiency and reducing production costs.

[0042] In some embodiments of this application, referring to Figures 7 and 8, the first positioning portion 23 is a positioning groove communicating with the first housing slot 22, and the ends of the multiple cables 4 slide smoothly into the first housing slot 22 by the fitting of the first positioning portion 23 and the second positioning portion 71, making it easy to embed the conductive support member 7 and the ends of the multiple cables 4 into the insulating body 2. At the same time, the positioning groove provides a certain locking and restricting effect on the ends of the conductive support member 7, preventing the conductive support member 7 from shaking, shifting position, or loosening within the insulating body 2.

[0043] In some embodiments of this application, referring to Figures 2, 7, 8, and 9, the second positioning section 71 includes a stepped structure 711, and the first positioning section 23 includes a stepped surface 231 that conforms to the stepped structure 711. The interaction between the stepped structure 711 and the conforming stepped surface 231 allows the conductive support member 7 to be positioned in at least two directions. Specifically, the horizontal plane of the stepped surface 231 can perform vertical positioning and regulating effects on the conductive support member 7, and the vertical plane of the stepped surface 231 can perform horizontal (e.g., left-right) positioning and regulating effects on the conductive support member 7.

[0044] Furthermore, the contact area between the stepped structure 711 and the stepped surface 231 is relatively large, and compared to point contact or line contact, multiple surface contact can provide more stable support and connection. The larger contact area distributes the force applied to the ends of the conductive support member 7, reducing local stress concentration, thereby increasing the overall load-bearing capacity and stability of the structure.

[0045] Furthermore, because the stepped structure 711 and the stepped surface 231 have unique shape and dimensional characteristics, assembly is only possible if both are correctly aligned during assembly. In this way, it is possible to prevent the conductive support member 7 from being oriented or positioned incorrectly during assembly, thereby greatly improving the accuracy and consistency of the assembly.

[0046] In some embodiments of this application, referring to Figures 7 and 9, the first positioning unit 23 further includes two restricting surfaces 232 provided opposite to both sides of the stepped surface 231, and the first positioning unit 23 can position the conductive support member 7 in at least three directions.

[0047] Specifically, the conductive support member 7 is provided with fitting surfaces 712 on both its front and rear sides to make close contact with the restricting surface 232. The restricting surface 232 positions itself by contacting the front and rear sides of the conductive support member 7, thereby performing a positioning and restricting action in the front-rear direction relative to the conductive support member 7.

[0048] Furthermore, in this application, the fitting of the first positioning part 23 and the second positioning part 71 enables the conductive support member 7 to be assembled and positioned inside the plug connector using only the insulating body 2. Since it is not necessary to rely on the metal housing 1 or the metal shielding member 5 to position the conductive support member 7, the positioning and assembly operations related to the conductive support member 7 and metal parts are eliminated, significantly simplifying the assembly procedure and improving assembly efficiency.

[0049] In some embodiments of this application, referring to Figures 2, 5, and 6, the metal shield member 5 is installed on the side of the conductive support member 7 opposite to the metal housing 1, and the metal shield member 5 is electrically connected to the conductive support member 7 and the metal housing 1, respectively. On the one hand, the fitting of the metal shield member 5 with the insulating body 2 provides fixing and restricting effects for the conductive support member 7, and on the other hand, the metal shield member 5 provides a electrically conductive connection between the conductive support member 7 and the metal housing 1, which is advantageous for grounding the conductive support member 7. A multi-directional three-dimensional shield structure is formed over the connection area between the core wire 41 and the connection portion 31.

[0050] In some embodiments of this application, referring to Figures 3 and 4, the metal housing 1 includes first side baffles 12 and second side baffles 13 provided on both sides of a first plate 11, and the metal shield member 5 includes first flanges 52 and second flanges 53 provided on both sides of a second plate 51. A first weld 121 is provided in the first side baffle 12, and a second weld 131 is provided in the second side baffle 13. The welding provides 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, enabling a conductive connection between the metal housing 1 and the metal shield member 5, while simultaneously preventing separation of the metal shield member 5 and the metal housing 1, and eliminating or minimizing the risk of loosening between the metal housing 1 and the metal shield member 5.

[0051] In some embodiments of this application, referring to Figure 7, a rib 26 is further provided on the outer circumference of the insulating body 2, and the flange of the metal shield member 5 is mechanically clamped by the fitting of the rib 26 with the corresponding side baffle, thereby limiting the misalignment of the first flange 52 and the second flange 53 after assembly is complete.

[0052] In some embodiments of this application, referring to Figures 1 and 4, a third weld 54 is provided in the metal shield member 5, which is provided in correspondence with the conductive support member 7 and is used to achieve a fixed connection between the metal shield member 5 and the conductive support member 7, thereby enabling a closer and more stable conductive contact between the conductive support member 7 and the metal shield member 5. During the use of electronic equipment, especially in situations with many moving parts or harsh working environments, secure fixing prevents separation of the metal shield member 5 and the conductive support member 7, thereby ensuring the integrity of the electromagnetic shielding structure. The first weld 121 and the second weld 131 may be through holes penetrating the side baffle, or grooves with reduced wall thickness in the weld area. The third weld 54 may be a through hole penetrating the second plate 51, or grooves with reduced wall thickness in the weld area. The first weld 121, the second weld 131, and the third weld 54 can be formed by CNC machining or press molding, providing accurate positioning for the corresponding welding operations.

[0053] In some embodiments of this application, referring to Figure 3, the metal housing 1 further includes a first extension region 14, a second extension region 15, and a locking baffle 16 integrally provided with the first plate 11, and is used to form a locking cavity on the metal housing 1 for locking a receptacle connector, thereby ensuring a secure connection between the plug connector and the receptacle connector.

[0054] In some embodiments of this application, referring to Figures 1, 4, and 7, the insulating body 2 is provided with a third positioning portion 24, and the edge of the metal shielding member 5 is provided with a fourth positioning portion 55. The fitting of the third positioning portion 24 and the fourth positioning portion 55 enables quick and accurate assembly and positioning between the insulating body 2 and the metal shielding member 5, preventing the metal shielding member 5 from shifting relative to the insulating body 2, thereby ensuring that the metal shielding member 5 provides an efficient shielding effect to the multiple plug terminals 3 provided on the insulating body 2.

[0055] Specifically, the interlocking of the third positioning portion 24 of the insulating body 2 and the fourth positioning portion 55 of the metal shielding member 5 forms a mechanical interlock, fixing the relative positions of the metal shielding member 5 and the insulating body 2. Even in environments with high vibration or thermal expansion and contraction, the interlocking of the third positioning portion 24 and the fourth positioning portion 55 suppresses displacement of the metal shielding member 5, thus preventing electromagnetic leakage due to displacement of the metal shielding member 5.

[0056] In some embodiments of this application, referring to Figures 5 and 6, the cable 4 includes a core wire 41, a first insulating layer 42, a shielding layer 43, and a second insulating layer 44, all arranged coaxially from inside to outside. Here, the core wire 41 is used to provide a conductive connection with the connection portion 31 of the plug terminal 3; the first insulating layer 42 is fitted outside the core wire 41 and is used to provide insulating protection for the core wire 41; the shielding layer 43 is fitted outside the first insulating layer 42 and is used to reduce electromagnetic interference to the core wire 41 from the outside; and the second insulating layer 44 is fitted outside the shielding layer 43 and is used to provide protection for the shielding layer 43.

[0057] The conductive support member 7 is integrally installed with the shield layers 43 of the multiple cables 4, enabling conductive contact between the conductive support member 7 and the shield layers 43 of the multiple cables 4. Furthermore, the shield layers 43 of the multiple cables 4 are electrically connected to the metal shield member 5 and the metal housing 1 via the conductive support member 7, forming a continuous and complete electromagnetic shielding system. This prevents external electromagnetic fields from interfering with signals inside the cables 4, suppresses the leakage of electromagnetic radiation generated by the cables 4 themselves to the outside, reduces electromagnetic contamination of surrounding electronic equipment, and significantly improves the stability and reliability of the plug connector in complex electromagnetic environments.

[0058] Furthermore, the integrated configuration of the conductive support member 7 and the shield layers 43 of the multiple cables 4 reduces the number of connection points between the shield layers 43 of the cables 4, simplifying the product structure and reducing design complexity. It also reduces the risk of failure due to loosening of connection points, corrosion, etc., thereby improving the overall stability and durability of the plug connector.

[0059] Specifically, as shown in Figure 6, the covering layers of multiple cables 4 are stripped off to expose the shield layers 43 of the cables 4 to the outside. Next, the portion of the multiple cables 4 with the exposed shield layers 43 is fixed inside the casting mold of the conductive support member 7, and molten tin is poured into the casting mold so that the molten tin covers the shield layers 43 of the multiple cables 4. Once the molten tin hardens, the conductive support member 7 and the shield layers 43 of the multiple cables 4 are connected as a single unit.

[0060] In some embodiments of this application, referring to Figures 5, 7, and 8, the plug terminal 3 further includes a contact portion 32, which is used to achieve mating and information transmission with a receptacle terminal in a receptacle connector with which it mates. The insulating body 2 is provided with a second housing slot 25 for installing the contact portion 32, thereby protecting the contact portion 32.

[0061] Referring to Figures 1 to 10, in some embodiments of this application, the assembly process of the plug connector is as follows:

[0062] Step 1: Position the metal housing 1 precisely.

[0063] Step 2: The insulating body 2, to which multiple plug terminals 3 are fixed, is embedded in the cavity of the metal housing 1, and the support portion 21 of the insulating body 2 is brought into close contact with the first plate 11 of the metal housing 1.

[0064] Step 3: Assemble the conductive support member 7 and the multiple cables 4 with the insulating body 2, and position the ends of the core wires 41 of the multiple cables 4 in a one-to-one correspondence with the connection parts 31 of the multiple plug terminals 3.

[0065] Step 4: The core wire 41 and its corresponding connection part 31 are welded together, and the welded connection area is double-supported by the support part 21 and the first plate 11.

[0066] Step 5: The insulating member 6 is fixedly installed on the side of the metal shield member 5 facing the core wire 41, and the metal shield member 5 is covered over the insulating body 2.

[0067] Step 6: The metal shield member 5, the metal housing 1, and the conductive support member 7 are fixed and electrically connected by welding.
