Description

Technical Field

[0001] This invention relates to the field of connector technology, and mainly to a foolproof and interference-resistant network port connector, particularly the insertion structure technology of a connector that relies on magnetic interconnection. Background Technology

[0002] With the continuous development of electronic products, connectors have been widely used for charging and signal transmission in electronic products. Connectors are adapting to performance trends such as faster speed, greater compatibility, and increased durability. As electronic products become increasingly feature-rich, the requirements for the alignment accuracy of RJ connectors are increasing. In the structural design for improving alignment accuracy, the gap between the plastic and the metal shell needs to be small. Conventional designs do not employ thermoforming between the plastic and the metal shell, which cannot meet the alignment requirements.

[0003] In addition, for EMI design, it is required to increase the contact area of ​​the spring to enhance EMI characteristics. However, after increasing the contact area, the product assembly force increases. Normally, the assembly force of a single product is required to be less than 80N. Conventional design will cause the panel installation force to exceed the specification. In conventional design, there is no high requirement for EMI characteristics, and the number of springs is small.

[0004] In addition, regarding the buckle design for both metal and plastic shells, the metal shell feet cannot be used as a conventional method to design buckles next to the metal shell feet, so there is a need for improvement. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a network connector that uses a thermoforming method to achieve a small gap between the plastic and the iron shell, while also improving the alignment accuracy using the thermoforming method.

[0006] To address the problems of the existing technology, the present invention adopts the following technical solution:

[0007] A network connector includes a base and a housing. The base is embedded in the housing. The housing includes a front housing and a rear housing. The rear housing has a plurality of positioning holes. The rear end of the base has positioning pins that match the positioning holes. The positioning pins of the base are aligned and pass through the positioning holes of the rear housing. The ends of the positioning pins completely cover the positioning holes.

[0008] The front housing has several first spring pieces at its end. Each first spring piece includes a narrowed bending section with a reduced width. The first spring piece is connected to the front housing through the narrowed bending section. A side groove is provided at the junction of the first spring piece and the narrowed bending section.

[0009] The side grooves are provided on both sides of the connection between the bent and narrowed part and the first spring piece;

[0010] Root grooves are provided on both sides of the connection between the bent and narrowed part and the front housing. The root grooves are located at the end of the front housing. Root grooves facing the front housing are provided on both sides of the connection between the bent and narrowed part and the front housing.

[0011] Furthermore, in some embodiments, the positioning post has an I-shaped structure, with its end covering the positioning hole.

[0012] Furthermore, in some embodiments, the end of the rear housing is provided with an inwardly bent buckle, and the bent portion of the buckle is provided with a pin extending outward from the end of the rear housing.

[0013] Furthermore, in some embodiments, the bending buckle has a slot adjacent to the end of the rear housing, and bending arms that are connected to the bending of the rear housing are provided on both sides of the slot. A pin is provided between the two bending arms, and the pin extending outward from the rear housing is located between the two bending arms.

[0014] Furthermore, in some embodiments, the top of the base is provided with a slot for matching the bent buckle, the bent buckle is embedded in the slot, and the slot is provided with a locking block that matches the locking opening of the bent buckle, the locking block abutting and engaging in the locking opening of the bent buckle.

[0015] Furthermore, in some embodiments, the side of the front housing is provided with a plurality of second spring pieces, the second spring pieces having the same structure as the first spring pieces, and the connection structure between the second spring pieces and the front housing is the same as the connection structure between the first spring pieces and the front housing.

[0016] Furthermore, in some embodiments, the bottom of the housing is provided with an inwardly bent hook piece, and the top edge of the base is provided with a limiting block that matches the hook piece, with the hook piece hooking onto the limiting block.

[0017] Furthermore, in some embodiments, the pins are provided with raised ribs.

[0018] Furthermore, in some embodiments, the front housing is provided with an opening, and the base is provided with a plug-in cavity that matches the opening, and a terminal assembly is provided in the plug-in cavity.

[0019] This invention is applicable to both transformer-equipped and transformerless network ports, as well as network ports of various shapes, such as 1X1, 1XN, and 2XN. The invention employs a design with grooves carved into the spring contacts, both on the sides and front end. This design improves the EMI characteristics of the product while meeting the panel mounting force requirements.

[0020] To improve alignment accuracy and reduce the gap between the plastic and the iron shell, this invention employs a thermoforming welding method to fix the positioning posts on the plastic base, thereby minimizing the gap between the plastic and the iron shell and improving alignment accuracy.

[0021] This invention employs a snap-fit ​​design that surrounds the metal shell prongs, enabling the plastic to snap onto the metal shell and allowing the metal shell prongs to snap onto the plastic base as well. Attached Figure Description

Figure 1 , Figure 6 , Figure 1 This is a three-dimensional schematic diagram of this application. Figure 6 This is an enlarged schematic diagram of the connector of this application with the middle part omitted. The base 11 of this application is embedded in the housing 30. The housing 30 includes a front housing 31 and a rear housing 35. An opening 32 is provided on the front housing 31.

[0037] Furthermore, in some embodiments, see [link to relevant documentation]. Figure 4 , Figure 4 This is a structural illustration of the housing 30 portion of this application. The front housing 31 has several first spring tabs 33 at its end and several second spring tabs 34 on its side. The bottom of the side of the housing 30 has an inwardly bent hook tab 39. The rear housing 35 has several positioning holes 38. The end of the rear housing 35 has an inwardly bent buckle 36. The bent part of the buckle 36 has a pin 37 extending outward from the end of the rear housing 35. Furthermore, the buckle 36 is perpendicular to the pin 37.

[0038] To further illustrate the features and technical means of this application, please refer to [link / reference]. Figure 5 and Figure 3 As shown, Figure 5 The three-dimensional structure of the 36 bent buckle parts of this application can be observed. Figure 3 The structural details of the product's bending buckle 36 are also shown; the bending buckle 36 has a slot 26 that is close to the end of the rear housing 35. On both sides of the slot 26, there are bending arms 24 that are connected to the rear housing 35 by bending. There is a pin 37 between the two bending arms 24. In other words, the pin 37 extending outward from the rear housing 35 is located between the two bending arms 24. The pin 37 has a rib 25.

[0039] Furthermore, in some embodiments, please refer to Figure 6 , Figure 7 , Figure 6 The enlarged schematic diagram shows the structural details of the 12-part insertion cavity. Figure 7 This is a three-dimensional schematic diagram of the base 11 of this application. The base 11 has a plug-in cavity 12 that matches the opening 32. The plug-in cavity 12 has a terminal assembly 13. The top of the base 11 has a slot 14 that matches the bending buckle 36.

[0040] Furthermore, in some embodiments, see [link to relevant documentation]. Figure 3 , Figure 3 The details of the matching between the bent buckle 36 and the locking block 17 are shown. The bent buckle 36 is embedded in the slot 14. The slot 14 is provided with a locking block 17 that matches the slot 26 of the bent buckle 36. The locking block 17 is engaged in the slot 26 of the bent buckle 36.

[0041] Furthermore, in some embodiments, see [link to relevant documentation]. Figure 2 As shown, Figure 2 This is a schematic diagram of the alignment of the positioning pins 16 and positioning holes 38 during pre-assembly. The rear end of the base 11 is provided with several positioning pins 16 that match the positioning holes 38. During alignment assembly, the positioning pins 16 of the base 11 are aligned and inserted into the positioning holes 38 of the rear housing 35. At this time, the outer end of the positioning pin 16 extends out of the outside of the positioning hole 38. During pre-assembly of the base 11, the positioning pins 16 of the base 11 are guided by the positioning holes 38 of the iron shell, thereby ensuring that the base 11 will not be misaligned during the pre-assembly process.

[0042] Then, the positioning post 16 is hot-press welded, see [reference]. Figure 3 , Figure 3 The image shows the position of the positioning post 16 after hot-press welding. The end of the positioning post 16 completely covers the positioning hole 38. The positioning post 16 forms an I-shaped structure. The positioning post 16 is used to fix the housing 30 (iron shell) and reduce the assembly gap between the iron shell and the plastic (base 11).

[0043] Furthermore, in some embodiments, see [link to relevant documentation]. Figure 9 , Figure 10 As shown, Figure 9 This is the 3D effect after hot-press welding of positioning post 16. Figure 10 It is the cross-sectional structure after hot-press welding of the positioning post 16. The end of the positioning post 16 covers the positioning hole 38, and the positioning post 16 tightly pulls the shell 30 to achieve a small gap between the plastic and the iron shell.

[0044] The positioning pin 16 is hot-pressed to cover the positioning hole 38, which makes the iron shell (shell 30) and the plastic (base 11) fit together and reduces the gap between them.
