[0047] Example 1

[0048] like Figure 2-7As shown, this embodiment provides an RJ45 connector, including a socket 1 and a plug 2. The socket 1 includes a slot 11, and at least one spring arm 12 is provided in the slot 11. The spring arm 12 is provided with a fastening part 121. The plug 2 is provided with a fastening engagement part 21 corresponding to the fastening part 121. The plug 2 can be inserted into the slot 11 in a first direction. The plug 2 can apply force to the spring arm 12 to make the spring arm 12 elastically deform. The fastening engagement part 21 can be fastened or disengaged from the fastening part 121.

[0049] In this embodiment of the RJ45 connector, the spring arm 12 can undergo elastic deformation and automatically reset. During the process of inserting the plug 2 into the slot 11, the engaging part 21 moves with the plug 2 to engage with the engaging part 121, thereby locking the plug 2 and the socket 1. During the process of pulling the plug 2 out of the slot 11, the engaging part 21 moves with the plug 2 to separate from the engaging part 121, thereby unlocking the plug 2 and the socket 1. At the same time, the plug 2 can apply force to the spring arm 12 to cause the spring arm 12 to undergo elastic deformation. This not only ensures the reliability of the engagement between the engaging part 121 and the engaging part 21, but also, compared with the prior art, the plug 2 can be inserted and removed without pressing, which can delay the aging of the RJ45 connector. Even if the plug 2 is forcibly pulled, it will not cause damage to the socket 1 and the plug 2, thus extending the service life and reliability of the RJ45 connector.

[0050] It should be noted that when the engaging part 21 and the engaging part 121 are engaged, it indicates that the plug 2 and the socket 1 are properly inserted. It is understood that the RJ45 connector also includes a first terminal 13 located in the socket 1 and a second terminal located in the plug 2. When the plug 2 and the socket 1 are properly inserted, the first terminal 13 and the second terminal are connected to achieve signal transmission.

[0051] Optionally, such as Figure 4 and Figure 5 As shown, the slot 11 includes a first sidewall A111 and a first sidewall B112 that are spaced apart from each other along a second direction, and the second direction is perpendicular to the first direction; the first terminal 13 is disposed on the first sidewall A111 and the spring arm 12 is disposed on the first sidewall B112, thereby avoiding interference between the spring arm 12 and the connection between the first terminal 13 and the second terminal, which not only facilitates the insertion or separation of the plug 2 and the socket 1, but also helps to improve the reliability of the RJ45 connector.

[0052] Specifically, such as Figure 2 As shown, the spring arm 12 is located in the middle of the first side wall B112 along the third direction, and the fastening part 21 is located in the middle of the plug 2 along the third direction. The first direction, the second direction and the third direction are perpendicular to each other, which can improve the uniformity of force on the plug 2, which is conducive to improving the connection reliability of the plug 2 and the socket 1, and extending the life of the plug 2.

[0053] Optionally, such as Figure 3 and Figure 4 As shown, the spring arm 12 includes a fixed end 122 and a free end 123 arranged opposite to each other. The fixed end 122 is connected to the socket 1. The fixed end 122 and the free end 123 are arranged sequentially along the direction in which the plug 2 is inserted into the slot 11. This not only makes the spring arm 12 less prone to excessive deformation, which is beneficial to improving the reliability of the spring arm 12 and extending the service life of the spring arm 12, but also helps to improve the smoothness of plug insertion and removal.

[0054] It should be noted that the spring arm 12 is located inside the slot 11, and the spring arm 12 can produce elastic deformation. In other words, the inner wall of the slot 11 is provided with a first clearance structure 14 corresponding to the spring arm 12, thereby reserving space for the spring arm 12 to produce elastic deformation through the first clearance structure 14.

[0055] Optionally, the first sidewall B112 is provided with a limiting part, and the spring arm 12 can generate elastic deformation and abut against the limiting part, thereby providing a certain support for the spring arm 12 through the limiting part, so as to prevent the spring arm 12 from being damaged due to excessive deformation.

[0056] Specifically, the first clearance structure 14 is a clearance gap provided between the spring arm 12 and the first side wall B112, and the limiting part is the wall surface of the first side wall B112. That is to say, during the process of inserting the plug 2 into the slot 11, the spring arm 12 undergoes elastic deformation under the action of the plug 2 and enters the clearance gap. When the spring arm 12 abuts against the wall surface of the first side wall B112, the wall surface of the first side wall B112 provides a certain support for the spring arm 12. When the fastening part 21 and the fastening part 121 are fastened together, the force on the spring arm 12 is reduced, and the deformation of the spring arm 12 is reduced, but it still has a certain amount of deformation, thereby ensuring the reliability of the connection between the fastening part 121 and the fastening part 21.

[0057] Optionally, such as Figures 2 to 6 As shown, the fastening part 121 is a fastening hole opened in the spring arm 12, and the fastening mating part 21 is a boss provided on the plug 2. By making the boss enter the fastening hole, the fastening part 121 and the fastening mating part 21 can be fastened together. This not only has a simple structure and is easy to operate, but also helps to reduce costs.

[0058] The boss includes a first surface and a second surface that are disposed opposite to each other along a first direction. When the boss is engaged with the fastening hole, along the first direction, the second surface is closer to the fixed end 122 of the spring arm 12 than the first surface.

[0059] Optionally, the first surface is provided with a first guide structure. During the process of inserting the plug 2 into the slot 11, the first surface will contact the spring arm 12. By providing the first guide structure on the first surface, the protrusion can be guided into the slot 11, thereby improving the smoothness of the plug 2 and the slot 11 insertion.

[0060] Optionally, the second surface is provided with a second guide structure. When the plug 2 is inserted into the socket 1, the boss is located in the engagement hole; when the plug 2 is pulled out of the slot 11, the second surface of the boss will abut against the wall of the engagement hole. By providing a second guide structure on the second surface, the boss can be guided to move out of the engagement hole, thereby improving the smoothness of the plug 2 being pulled out.

[0061] Specifically, such as Figure 6 As shown, the first guide structure is a first arc-shaped surface 211, and the second guide structure is a second arc-shaped surface 212. The first arc-shaped surface 211 and the second arc-shaped surface 212 are located on both sides of the boss along the first direction, thereby making the outer surface of the boss have a semi-circular structure to improve the smoothness of the plug 2 and the slot 11 insertion.

[0062] In this embodiment, the spring arm 12 is set at an angle to the first direction. In other words, the spring arm 12 is set at an angle, and the free end 123 of the spring arm 12 is closer to the plug 2 than the fixed end 122. This can improve the fastening reliability of the fastening part 121 and the fastening connection part through the spring arm 12.

[0063] It should be noted that the insertion and removal feel of the plug 2 can be adjusted by adjusting the angle between the spring arm 12 and the first direction, as well as the height of the boss.

[0064] Optionally, such as Figure 3 As shown, the free end 123 of the spring arm 12 is provided with a first protrusion 124, which can abut against the limiting part. It should be noted that by abutting against the limiting part with the first protrusion 124, the spring arm 12 can abut against the limiting part as soon as possible during the insertion of the plug 2 into the slot 11, thereby increasing the feel of plug 2 insertion and removal without changing the tilt angle of the spring arm 12, which is beneficial to protecting the spring arm 12. Moreover, during the insertion and removal of the plug 2, there is always a certain gap between the spring arm 12 and the first side wall B112, which provides space for the elastic deformation of the spring arm 12 and ensures the smooth engagement or disengagement of the fastening part 121 and the fastening mating part 21.

[0065] Optionally, a foolproof structure is provided between the plug 2 and the socket 1 to prevent the plug 2 from being mis-inserted, thereby improving the convenience and accuracy of plug-in connection between the plug 2 and the socket 1.

[0066] For example, the foolproof structure includes a foolproof protrusion 31 on the inner wall of the slot 11 and a foolproof groove 32 on the plug 2. When the plug 2 is inserted into the socket 1, the plug 2 can only be inserted into the slot 11 by aligning the foolproof protrusion 31 and inserting it into the foolproof groove 32, thereby achieving the purpose of foolproofing. Of course, the foolproof protrusion 31 can also be provided on the plug 2, and the foolproof groove 32 can be provided on the inner wall of the slot 11.

[0067] Optionally, such as Figure 5 and Figure 6 As shown, there are two anti-mistake protrusions 31 and two anti-mistake grooves 32, and the anti-mistake protrusions 31 and anti-mistake grooves 32 are arranged in a one-to-one correspondence. The two anti-mistake protrusions 31 are located on both sides of the plug 2, which can improve the uniformity of force on the plug 2, thereby improving the reliability of the plug 2 and socket 1 and protecting the plug 2.

[0068] It should be noted that, as Figure 3 and Figure 4 As shown, the socket 1 in this embodiment includes a plastic body 1a and a metal shell 1b. The metal shell 1b is fitted onto the outside of the plastic body 1a. A slot 11 is provided on the plastic body 1a, and the metal shell 1b has an opening corresponding to the slot 11. The fixed end 122 of the spring arm 12 is connected to the metal shell 1b, and the free end 123 of the spring arm 12 extends into the slot 11. Exemplarily, the spring arm 12 and the metal shell 1b are integrally formed, that is, the spring arm 12 is made of metal, which not only helps to improve the structural strength of the spring arm 12, but also facilitates its manufacture.

[0069] Furthermore, such as Figure 7 As shown, the plug 2 in this embodiment includes a plastic head body 2a and a metal head shell 2b (such as an iron shell). The metal head shell 2b is fitted onto the outside of the plastic head body 2a, and the fastening part 21 is provided on the metal head shell 2b. As an alternative, the plug 2 may also include only the plastic head body 2a. In other words, the plug 2 may not include the metal head shell 2b, in which case the fastening part 21 is provided on the plastic head body 2a.

[0070] In this embodiment of the RJ45 connector, the plug 2 can apply force to the spring arm 12 to cause the spring arm 12 to undergo elastic deformation. This not only ensures the reliability of the engagement between the fastening part 121 and the fastening mating part 21, meeting the industry's signal transmission requirements, but also, compared with the prior art, the plug 2 can be inserted and removed without pressing, which can delay the aging of the RJ45 connector. Even if the plug 2 is forcibly pulled, it will not cause damage to the socket 1 and the plug 2, thus having almost no maintenance costs and making it easier to bring to market.

[0071] Example 2

[0072] like Figure 8 and Figure 9 As shown, the difference between this embodiment and Embodiment 1 is that: at least two spring arms 12 are provided, and at least two spring arms 12 are spaced apart on the first side wall B112. That is, the plug 2 is provided with a fastening engagement part 21 corresponding to the fastening part 121 of the at least two spring arms 12. The fastening part 121 can fasten or disengage with the corresponding fastening engagement part 21, thereby further improving the connection reliability between the plug 2 and the socket 1.

[0073] It should be noted that the socket 1 in this embodiment includes a second clearance structure 15 disposed on the first side wall B112 of the slot 11. Specifically, the second clearance structure 15 is disposed in correspondence with the press-type spring arm of the existing plug, so as to reserve space for the press-type spring arm through the second clearance structure 15, so that the socket 1 in this embodiment can be adapted to the plug with the press-type spring arm in the prior art.

[0074] Optionally, at least two spring arms 12 are respectively disposed on both sides of the second clearance structure 15, thereby enabling the socket 1 of this embodiment to be compatible with existing plugs and the plug 2 of this embodiment, thereby expanding the versatility of the RJ45 connector of this embodiment, making it easier to bring to market and meet different needs.

[0075] Specifically, two spring arms 12 are provided, with each spring arm 12 located on one side of the second clearance structure 15 along a third direction. Furthermore, the plug 2 has a locking engagement portion 21 corresponding to the locking portions 121 of the two spring arms 12. This arrangement not only improves the connection reliability between the plug 2 and the socket 1 and the versatility of the RJ45 connector, but also avoids excessively increasing the complexity of the RJ45 connector, facilitating manufacturing and reducing costs.

[0076] Example 3

[0077] like Figures 10 to 13 As shown, the difference between this embodiment and Embodiment 1 is that the slot 11 includes two second sidewalls 113 arranged opposite each other along a third direction, and each of the two second sidewalls 113 is provided with a spring arm 12. That is to say, the plug 2 is provided with a fastening engagement part 21 on both sides along the third direction, which can be fastened or separated from the fastening part 121 of the corresponding spring arm 12, thereby further improving the connection reliability between the plug 2 and the socket 1.

[0078] It should be noted that, as Figure 10 and Figure 11 As shown, the socket 1 of this embodiment includes a second clearance structure 15 disposed on the first side wall B112 of the slot 11. Specifically, the second clearance structure 15 is disposed in correspondence with the press-type spring arm of the existing plug, so as to reserve space for the press-type spring arm through the second clearance structure 15, so that the socket 1 of this embodiment can be adapted to the plug with the press-type spring arm in the prior art.

[0079] The RJ45 connector of this embodiment, by providing spring arms 12 on both second sidewalls 113, improves the connection reliability between the plug 2 and the socket 1, and enables the socket 1 of this embodiment to be compatible with existing plugs and the plug 2 of this embodiment, thereby expanding the versatility of the RJ45 connector of this embodiment, making it easier to bring to market and meet different needs.

[0080] Optionally, the fastening part 121 is a fastening protrusion provided on the spring arm 12, and the fastening mating part 21 is a fastening groove provided on the plug 2. By allowing the fastening protrusion to enter the fastening groove, the fastening part 121 and the fastening mating part 21 can be fastened together. This not only has a simple structure and is easy to operate, but also helps to reduce costs.

[0081] Optionally, along a third direction, the spring arm 12 includes a first arm surface facing the plug 2 and a second arm surface facing away from the plug 2; a fastening protrusion is provided on the first arm surface and a first groove 125 is formed on the second arm surface, which not only facilitates the elastic deformation of the spring arm 12 and improves the smoothness of plug insertion and removal, but also helps to simplify the structure of the spring arm 12, reduce the volume of the spring arm 12, and facilitate manufacturing. It is understood that the plug 2 has fastening grooves on both sides along a third direction that can engage with the corresponding fastening protrusions of the spring arm 12.

[0082] Specifically, there are two spring arms 12 and two fastening grooves, and the fastening protrusions of the spring arms 12 correspond one-to-one with the fastening grooves. The two spring arms 12 are located on the two second side walls 113 respectively, and the two fastening grooves are located on both sides of the plug 2 along the third direction. This not only improves the connection reliability between the plug 2 and the socket 1 and the universality of the RJ45 connector, but also avoids excessively increasing the complexity of the RJ45 connector, making it easier to process and reducing costs.

[0083] Optionally, the free end 123 of the spring arm 12 is provided with a second protrusion 126, which is located on the second arm surface and forms a second groove 127 on the first arm surface. That is, both the fastening protrusion and the second protrusion 126 are formed by bending the spring arm 12 through stamping or other methods, and the fastening protrusion and the second protrusion 126 protrude in opposite directions. This avoids the problem that when the spring arm 12 undergoes elastic deformation, the fastening protrusion may fold over (i.e., the fastening protrusion folds over and protrudes onto the second arm surface), thus affecting the connection reliability between the fastening part 121 and the fastening mating part 21.

[0084] Optionally, the fastening protrusion includes a third guide structure. Along the first direction, the third guide structure is located on the side of the fastening protrusion near the fixed end 122 of the spring arm 12, thereby guiding the plug 2 into the slot 11 through the third guide structure, improving the smoothness of the plug 2 and socket 1 connection.

[0085] Optionally, the fastening protrusion includes a fourth guide structure. Along the first direction, the fourth guide structure is located on the side of the fastening protrusion away from the fixed end 122 of the spring arm 12, thereby guiding the plug 2 out of the slot 11 through the fourth guide structure and improving the smoothness of the plug 2 being pulled out.

[0086] Specifically, the third guide structure is the first inclined surface 1211, and the fourth guide structure is the second inclined surface 1212. The first inclined surface 1211 and the second inclined surface 1212 have opposite inclination directions, which makes the fastening protrusion roughly triangular. The structure is simple and easy to process.

[0087] Furthermore, the inner wall of the fastening groove includes a third inclined surface 213 corresponding to the first inclined surface 1211. In other words, when the fastening protrusion and the fastening groove are fastened together, the first inclined surface 1211 and the third inclined surface 213 fit tightly together, thereby improving the stability of the plug 2 and the socket 1 connection.

[0088] Furthermore, the inner wall of the fastening groove includes a fourth inclined surface 214 corresponding to the second inclined surface 1212. In other words, when the fastening protrusion and the fastening groove are fastened together, the second inclined surface 1212 and the fourth inclined surface 214 fit tightly together, thereby improving the stability of the plug 2 and the socket 1 connection.

[0089] It should be noted that in this embodiment, the plug 2 does not include the head metal shell 2b, and the fastening engagement part 21 is provided on the head plastic body 2a. As an alternative, the plug 2 may also include a head plastic body 2a and a head metal shell 2b, with the head metal shell 2b sleeved on the outside of the head plastic body 2a, the fastening engagement part 21 provided on the head plastic body 2a, and the head metal shell 2b having a through hole or other clearance structure C corresponding to the fastening engagement part 21, thereby enabling the fastening engagement part 21 to be fastened or disengaged from the fastening part 121.
