Description

Technical Field

[0001] The utility model relates to the technical field of network connection equipment, in particular to an RJ45 socket and an RJ45 connector. Background Art

[0002] The RJ45 connector, a compact network interface, is at the heart of modern Ethernet communications. It seamlessly connects computers, routers, switches, modems, and other network devices, making data transfer, file sharing, and network communications seamless and efficient.

[0003] The RJ45 connector consists of two parts: a plug, commonly called a connector or plug, and a socket, also called a module. The perfect fit between the plug and socket ensures electrical continuity. The plug is made of plastic and consists of a main body (or plug body) and a retaining bar. The elastic design of the retaining bar ensures that the plug fits securely into the socket, maintaining circuit continuity.

[0004] However, over time and with repeated plugging and unplugging, the latching strip can fatigue and break. Once damaged, the plug loses its stable connection to the receptacle. This can cause the plug to fall out of the receptacle and can also lead to poor contact between the pins on the connector and the pins inside the receptacle, affecting signal transmission and hindering proper function of the connector. Utility Model Content

[0005] In order to overcome at least one of the defects of the above-mentioned prior art, one of the purposes of the present invention is to provide an RJ45 socket, in which a first spring piece is arranged inside the RJ45 socket. After the clamping strip on the plug breaks, the elastic potential released by the first spring piece can exert an extrusion force on the plug. This extrusion force can keep the plug in the RJ45 socket and connect it to the pin inside the RJ45 socket.

[0006] In order to overcome at least one of the defects of the above-mentioned prior art, the second purpose of the present invention is to provide an RJ45 connector, which is applied with the aforementioned RJ45 socket.

[0017] Furthermore: a second spring piece is also provided in the functional cavity, and a detection circuit for detecting whether the plug is in place is connected to the second spring piece; after the plug is placed in the functional cavity, the first spring piece is pressed toward the second spring piece to make the detection circuit conductive.

[0018] Furthermore, a second limiting slot is provided on the second inner surface; the second elastic piece is bent, and includes an end portion 1 and an end portion 2, the end portion 1 is inserted into the second limiting slot, and the end portion 2 is placed in the functional cavity;

[0038] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0039] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0041] See Figure 1 and Figure 2 The utility model discloses an RJ45 socket 10. Figures 3 to 5 The present invention discloses an RJ45 connector, which includes an RJ45 socket 10 and a plug 20. When the RJ45 connector is in operation, the plug 20 is inserted into the RJ45 socket 10 and electrically connected to the RJ45 socket 10. To facilitate further understanding of this solution by those skilled in the art, the RJ45 socket 10 and the RJ45 connector are described in detail below.

[0042] An RJ45 socket 10 includes a socket body 1, a functional cavity 5 is provided in the socket body 1, and a pin 2 is provided in the functional cavity 5. When the RJ45 socket 10 is in operation, a plug 20 is placed in the functional cavity 5 and electrically connected to the pin 2.

[0043] A first spring piece 7 is also provided in the functional cavity 5. At least after the clamping strip 22 on the plug 20 placed in the functional cavity 5 is broken, the first spring piece 7 contacts the plug 20 and releases elastic potential energy to keep the plug 20 and pin 1 2 electrically connected.

[0044] Based on the above scheme, if Figure 3 and Figure 4 In the state shown, the plug 20 is placed in the socket body 1 and is connected to the pin 2 installed in the functional cavity 5 in the socket body 1. Figure 3 and Figure 4As shown, when the socket clamping strip 22 is intact, the clamping strip 22 keeps the plug 20 fixedly connected to the socket body 1 and ensures electrical continuity between the plug 20 and pin 1 2. When the socket clamping strip 22 is intact, after the plug 20 is placed in the socket body 1, the plug 20 presses against the first spring piece 7 in the functional cavity 5. Based on the action and reaction forces, the first spring piece 7 deforms, exerting a squeezing force on the socket body 1. This squeezing force further connects the plug 20 to the socket body 1, ensuring a secure connection between the plug 20 and the socket body 1 and electrical continuity between the plug 20 and pin 1 2 in the functional cavity 5.

[0045] like Figure 5 In the state shown, after the clamping strip 22 on the plug 20 breaks, the plug 20 continues to be placed in the socket body 1. The same plug 20 will squeeze the first spring piece 7 in the socket body 1, and the first spring piece 7 will also apply a squeezing force to the plug 20. This squeezing force ensures that the plug 20 is stably maintained in the functional cavity 5 of the socket body 1, and at the same time ensures that the plug 20 and the pin 1 2 in the functional cavity 5 are in a conductive state, preventing the plug 20 from falling off the socket body 1 or the plug 20 partially detaching from the functional cavity 5, and preventing the pin 2 on the plug 20 from being separated from the pin 1 2 in the functional cavity 5 or being in a poor contact state.

[0046] Therefore, in summary, based on the above solution, regardless of whether the retaining strip 22 on the plug 20 is broken, after the plug 20 is inserted into the functional cavity 5 and in place, the plug 20 will squeeze the first spring piece 7, causing the first spring piece 7 to elastically deform and store elastic potential energy. Conversely, the first spring piece 7 will release the elastic potential energy or have a tendency to release the elastic potential energy, and the first spring piece 7 will apply a squeezing force to the plug 20 in the functional cavity 5. This squeezing force keeps the plug 20 stably in the functional cavity 5 and electrically connected to the pin 1 2 in the functional cavity 5. In other words, regardless of whether the retaining strip 22 on the plug 20 is broken, the first spring piece 7 ensures a reliable connection between the plug 20 and the socket body 1, and ensures electrical connection between the plug 20 and the pin 1 2 in the functional cavity 5 in the socket body 1.

[0047] That is, based on the above solution, the RJ45 socket 10 is cleverly configured with a first spring 7. When the plug 20 is inserted into the socket's functional cavity 5, the first spring 7 immediately contacts the plug 20. The elastic force released by the first spring 7 compresses the plug 20. Even if the retaining bar 22 of the plug 20 breaks, the elastic force of the first spring 7 ensures that the connection between the socket and the plug 20 remains secure, maintaining continuous electrical conduction between the plug 20 and the RJ45 socket 10. In other words, the RJ45 socket 10 in this solution ensures that even if the retaining bar 22 is damaged, the connection between the RJ45 socket 10 and the plug 20 is not interrupted, and signal transmission remains unimpeded.

[0048] In this technical solution, the functional cavity 5 has a first inner surface 13 and a second inner surface 14 disposed opposite each other. Pin 1 2 is fixed to the first inner surface 13, and the first spring 7 is disposed on the second inner surface 14. After the plug 20 is placed in the functional cavity 5, it is fixed between pin 1 2 and the first spring 7. The first spring 7 presses the plug 20 toward pin 1 2 at least after the retaining strip 22 on the plug 20 breaks.

[0049] like Figure 4 and Figure 5 In the viewing angle, first inner surface 13 is located above second inner surface 14. With retaining strip 22 on plug 20 intact, once plug 20 is placed within functional cavity 5, it contacts and establishes electrical continuity with pin 1 2 on first inner surface 13. At this point, first spring 7 also compresses plug 20 toward first inner surface 13, further facilitating contact and electrical continuity between plug 20 and pin 1 2 on first inner surface 13. This ensures that plug 20 is stably secured within functional cavity 5 of socket body 1, ensuring proper operation of the connector comprising plug 20 and socket.

[0050] like Figure 4 and Figure 5 In the viewing angle state, the first inner surface 13 is located above the second inner surface 14. When the retaining strip 22 on the plug 20 is broken, the side door of the plug 20 facing the second inner surface 14 contacts the first spring piece 7 and is pressed toward the first inner surface 13 by the first spring piece 7. This effectively restrains and secures the plug 20 within the functional cavity 5 and allows electrical connection with the pin 1 2 on the second inner surface 14 within the functional cavity 5. Therefore, the first spring piece 7 presses the plug 20 toward the pin 1 2 at least after the retaining strip 22 on the plug 20 is broken.

[0051] Of course, as the installation direction of the plug 20 is different, the first inner surface 13 is not necessarily above the second inner surface 14, but the first inner surface 13 and the second inner surface 14 are arranged opposite to each other, and after the plug 20 is inserted into the functional cavity 5, the plug 20 squeezes the first spring piece 7 toward the first inner surface 13, and the first elastic member squeezes the plug 20 in the opposite direction to the first inner surface 13, so that the plug 20 is restricted and fixed in the functional cavity 5 and remains conductive with the pin 2 fixed on the second inner surface 14.

[0052] In the above scheme, the first inner surface 13 and the second surface are arranged opposite to each other, and the pin 2 is arranged on the first inner surface 13, and the first spring piece 7 is arranged on the second inner surface 14. The deformed first spring piece 7 presses the plug 20 toward the first inner surface 13, on the one hand ensuring that the plug 20 is firmly fixed in the functional cavity 5, and on the other hand ensuring that the plug 20 is in contact with the pin 2 on the first inner surface 13 and conductive.

[0053] In this technical solution, a first retaining slot 11 is provided on the second inner surface 14. The first spring piece 7 is bent and includes a first end 71, a second end 72, and a bent portion located between the first and second ends 71 ​​and 72. The first end 71 is inserted into the first retaining slot 11, and the second end 72 is positioned within the functional cavity 5. When the plug 20 is inserted into the functional cavity 5, the plug 20 contacts the back of the bent portion and presses the first spring piece 7 toward the second inner surface 14.

[0054] A first limiting slot 11 is provided to achieve fixation and installation of the first end 71 of the first spring piece 7. The size of the first limiting slot 11 is adapted to the external size of the first end 71. Combined with the extrusion of the first spring piece after the plug 20 is placed in the functional cavity 5, the fixation and installation of the first spring piece 7 in the functional cavity 5 are achieved, making the installation and setting of the first spring piece 7 in the functional cavity 5 simple and reliable.

[0055] In the above scheme, if Figure 4 As shown, the plug 20 contacts the bent portion of the bent first spring piece 7, specifically, the back of the bent portion, with the back of the bent portion facing the first inner surface 13. The plug 20 applies an extrusion force to the back of the bent portion, so that the first spring piece 7 obtains elastic potential energy, and the bent portion releases the elastic potential energy, squeezing the plug 20 toward the first inner surface 13, so that the plug 20 is fixed in the functional cavity 5 and electrically connected to the pin 1 2 on the first inner surface 13.

[0056] After the plug 20 is placed in the functional cavity 5, it contacts the back of the bent portion, pressing the first spring piece 7 toward the second inner surface 14. Conversely, the first spring piece 7 presses the plug 20 toward the first inner surface 13. The back-to-back contact between the plug 20 and the bent portion effectively stores energy in the first spring piece 7, ensuring that the first spring piece 7 has sufficient potential energy. This allows the first spring piece 7 to exert a sufficiently strong pressure on the plug 20, ensuring that the plug 20 remains within the functional cavity 5 and is electrically connected to the pin 1 2 within the functional cavity 5.

[0057] In this technical solution, to ensure that the first spring piece 7 has sufficient potential energy and exerts a sufficiently strong pressure on the plug 20, the bent portion includes a first straight portion 73, a second curved portion 74, a third connecting portion 75, and a fourth straight portion 76, which are connected in sequence. The first end 71 and the second end 72 are respectively disposed on the first straight portion 73 and the fourth straight portion 76. When the plug 20 is placed in the functional cavity 5, it contacts the back of the second curved portion 74 and presses the second curved portion 74 against the second inner surface 14.

[0058] In order to enable the first spring piece 7 to obtain sufficient potential energy and at the same time make the first spring piece 7 to exert a sufficiently large extrusion force on the plug 20, the second curved portion 74 is arc-shaped, the third connecting portion 75 is basically parallel to the first straight portion 73, the fourth straight portion 76 is basically perpendicular to the first straight portion 73, and the second curved portion 74 is curved, with the curved back facing the first inner surface 13.

[0059] The first limiting slot 11 is a through slot that penetrates the socket body 1. The first end 71 and the first straight portion 73 pass through the first limiting slot 11. The fourth straight portion 76 is substantially parallel to the second inner surface 14 and is located on the second inner surface 14. In conjunction with the plug 20, the second curved portion 74 is pressed toward the second inner surface 14 to install and secure the first spring piece 7 in the functional cavity 5, preventing the first spring piece 7 from moving or shifting within the functional cavity 5.

[0060] In addition, in the above scheme, the first end 71 is inserted into the first limiting slot 11, and the second end 72 is a free end, which is placed in the functional cavity 5. In this way, the plug 20 can apply a greater extrusion force to the first spring piece 7, so that the first spring piece 7 can obtain a greater deformation. The first spring piece 7 will not affect the insertion of the plug 20 into the functional cavity 5, so that the plug 20 can be inserted into the functional cavity 5 more smoothly.

[0061] In this technical solution, the second curved portion 74 slopes downward from the end near the third connecting portion 75 to the end near the first straight portion 73. The second curved portion 74 is at least partially oriented toward and in contact with the plug 20. The second curved portion 74 is at least partially squeezed by the plug 20 or squeezes the plug 20 toward the first inner surface 13, ensuring that the plug 20 remains within the functional cavity 5 and is electrically connected to the pin 1 2 within the functional cavity 5.

[0062] like Figure 4 and Figure 5 As shown, in the functional cavity 5, assuming that the end of the functional cavity 5 close to the plug interface 6 is the outer end, and the end opposite to the outer end is the inner end, the second bent portion 74 is inclined downward from the end close to the third connecting portion 75 to the end close to the first straight portion 73, that is, the second bent portion 74 is arranged to be inclined downward from the inner end to the outer end, which is convenient for the plug 20 to be inserted into the functional cavity 5, and more convenient for the plug 20 to contact and squeeze the first elastic sheet 7 after the plug 20 is inserted into the functional cavity 5. At the same time, after the plug 20 is inserted into the functional cavity 5, the plug 20 has a sufficiently large contact area with the second bent portion 74, which can avoid unnecessary deformation of the second bent portion 74, and also facilitate the controllable direction of the extrusion force applied by the second bent portion 74 to the plug 20.

[0063] In this technical solution, a second spring piece 8 is further provided in the functional cavity 5. A detection circuit is connected to the second spring piece 8 to detect whether the plug 20 is in place. Specifically, after the plug 20 is inserted into the functional cavity 5, the plug presses the first spring piece 7 toward the second spring piece 8, causing the detection circuit connected to the second spring piece 8 to conduct.

[0064] Based on the above scheme, the detection circuit is used to detect whether the plug 20 is inserted into the functional cavity 5. The plug 20 is inserted into the functional cavity 5 on the socket body 1, including that the plug 20 is electrically conductive with the pin 2, and that the plug 20 is stably and reliably connected in the functional cavity 5, and that the plug 20 will not fall out of the functional cavity 5 or separate from the pin 2 after the insertion action is removed.

[0065] In the above solution, the first spring piece 7 is squeezed by the plug 20, so that the first spring piece 7 contacts the second spring piece 8 or certain parts of the first spring piece 7 contact certain parts of the second spring piece 8, thereby realizing the conduction of the detection circuit and realizing the detection of whether the plug 20 is inserted in place.

[0066] The above-described detection scheme and the provision of the second spring 8 ensure that even after the retaining strip 22 on the plug 20 breaks, the state of the plug 20 within the functional cavity 5 can be quickly determined, and the connection status of the plug 20 with the socket body 1 and the conductive status between the plug 20 and the pin 1 2 can be quickly determined. This effectively avoids the problem of not being able to quickly detect the plug 20 falling out of the functional cavity 5 or the plug 20 being disconnected from the socket body 1. It also effectively avoids the wasteful discarding of the plug 20 due to the direct judgment that the plug 20 cannot be connected to the socket body 1 after the retaining strip 22 breaks.

[0067] The above detection scheme and the setting of the second spring 8 can also quickly detect and find connectors that are not fully connected or not connected or not conductive when there are a large number of RJ45 connectors, reducing troubleshooting time and improving maintenance efficiency.

[0068] In this technical solution, a second limiting slot 12 is provided on the second inner surface 14 . The second elastic piece 8 is bent and includes a first end 81 and a second end 82 . The first end 81 is inserted into the second limiting slot 12 , and the second end 82 is placed in the functional cavity 5 .

[0069] The second elastic piece 8 includes a straight portion 1 83 and a straight portion 2 84 connected to each other, the end 1 81 and the end 2 82 are respectively arranged on the straight portion 1 83 and the straight portion 2 84, the straight portion 2 84 is placed in the functional cavity 5, and the detection circuit is connected to the straight portion 2 84.

[0070] The plug 20 inserted into the functional cavity 5 presses the second spring piece 8 against the second straight portion 84 and turns on the detection circuit. The first straight portion 83 and the second straight portion 84 are substantially vertical.

[0071] In the above solution, the second spring clip 8 is installed and fixed via the second limiting slot 12. Furthermore, the second limiting slot 12 is a through slot extending through the socket body 1, with the first end portion 81 and the first straight portion 83 passing through the second limiting slot 12 to facilitate installation of the second spring clip 8. The second end portion 82 is a free end positioned within the functional cavity 5. When the first spring clip 7 compresses the second spring clip 8, the first spring clip 7 can apply pressure to the second spring clip 8, thereby facilitating conduction of the detection circuit connected to the second spring clip 8. Furthermore, the second spring clip 8 can prevent the first spring clip 7 from obstructing the insertion of the plug 20.

[0072] In this technical solution, the socket body 1 includes a plastic shell body 9, a metal shield 4, and a pin-1 retaining bracket 3. A functional cavity 5 is disposed within the plastic shell body 9, the metal shield 4 covers the outer surface of the plastic shell body 9, and the pin-1 retaining bracket 3 secures pin 2 within the functional cavity 5. The metal shield 4 provides signal shielding while reinforcing the plastic shell body 9 and preventing deformation.

[0073] In this technical solution, the plastic shell body 9 is provided with an insertion port 6, and the metal shield 4 is provided with a relief opening adapted to the insertion port 6. The plug is inserted into the functional cavity 5 through the insertion port 6 and the relief opening. The metal shield 4 not only provides signal shielding, but also strengthens the plastic shell body 9 and prevents deformation of the insertion port 6 on the plastic shell body 9.

[0074] This technical solution also provides an RJ45 connector. The RJ45 connector includes a plug 20 and the aforementioned RJ45 socket 10. Plug 20 includes a plug body 21 and a clip 22 elastically connected to the plug body 21. Pin 2 is provided on the plug body 21. When the plug body 21 is inserted into the functional cavity 5, pin 2 is electrically connected to pin 1 2.

[0075] The clamping strip 22 faces the second inner surface 14, and after the plug 20 is inserted into the functional cavity 5, the clamping strip 22 extends from the plug interface 6 and squeezes the plug body 21 toward the two sides of the pins. The clamping strip 22 realizes the fixed connection between the plug body 21 and the RJ45 socket 10. Generally, when the clamping strip 22 on the plug 20 is intact, the clamping strip 22 can independently fix the plug 20 on the RJ45 socket 10. After the clamping strip 22 on the plug breaks, the fixing effect of the clamping strip 22 on the plug 20 disappears. At this time, the first spring piece 7 arranged in the functional cavity 5 in the RJ45 socket 10 fixes the plug body 21 in the functional cavity 5 and ensures that pin 2 on the plug body 21 is electrically conductive with pin 1-2 in the RJ45 socket 10. Of course, when the card strip 22 on the plug 20 is intact, the first spring piece 7 also squeezes the plug body 21 to further ensure the fixed connection between the plug 20 and the RJ45 socket 10. At this time, due to the squeezing effect of the first spring piece 7, the effect of the card strip 22 can be appropriately reduced, the fatigue of the card strip 22 can be reduced, the service life of the card strip 22 can be extended, and the probability of the card strip 22 breaking can be reduced.

[0076] After the plug body 21 is inserted into the functional cavity 5 , the first spring piece 7 is located inside the clamping strip 22 , and the first spring piece 7 presses the plug body 21 toward two sides of the pins.

[0077] The RJ45 connector of this solution utilizes the aforementioned RJ45 jack 10. This ensures that even if the retaining strip 22 of the plug 20 breaks, the plug 20 maintains a tight and stable connection with the RJ45 jack 10, ensuring unimpeded signal transmission. This not only ensures the reliability of the RJ45 connector in the face of challenging conditions, but also significantly extends its service life.

[0078] Pin 2 is not shown in the figure. Pin 2 is a conventional structure on the plug 20. In this solution, no creative improvement is made to the structure and position of pin 2 on the plug 20. After the plug 20 is inserted into the functional cavity 5 in the socket body 1 and is in place, pin 2 on the plug 20 contacts pin 1 2 in the socket body 1 and is electrically connected, and the plug 20 is connected to the RJ45 socket 10.

[0079] In the above scheme, after the plug body 21 is inserted into the functional cavity 5, the first spring piece 7 is located on the inner side of the clamping strip 22, which facilitates the insertion of the plug body 21 into the functional cavity 5 and prevents the first spring piece 7 from affecting the normal insertion operation of the plug body 21, so that the plug body 21 can be inserted into the RJ45 socket 10 conveniently and quickly, and also facilitates the removal of the plug 20 from the RJ45 socket 10.

[0080] The plug body 21 and the clip 22 are integrally connected, and both are made of plastic. This integral connection simplifies the structure of the plug 20, simplifies the production process, and improves production efficiency. It also facilitates the elastic connection between the plug body 21 and the clip 22, ensuring a reliable connection between the clip 22 and the plug body 21.

[0081] In this technical solution, a limiting protrusion 23 is provided on the side of the plug body 21 facing the second inner surface 14. After the plug body 21 is inserted into the functional cavity 5, the limiting protrusion 23 is located inside the first spring plate 7 along the insertion direction of the plug body 21. The first spring plate 7 abuts the limiting protrusion 12 and limits the plug body 21 from being removed from the functional cavity 5. In other words, to further ensure that the first spring plate can still maintain the plug body 21 in the functional cavity 5 after the clamping strip 22 on the plug 20 breaks, and to ensure electrical connection between pin 2 on the plug and pin 1 2 in the RJ45 socket 10, the limiting protrusion 23 is provided on the plug body 21. The limiting protrusion 23 protrudes toward the second inner door side and is located inside the first spring plate 7 along the insertion direction of the plug 20. The limiting protrusion 23 is thus limited by the first spring plate 7 to prevent the plug 20 from being removed. If the plug 20 is to be removed from the functional cavity 5, the limiting protrusion 23 needs to press the first spring piece 7 toward the second inner surface 14 before it can be removed. On the contrary, the first spring piece 7 limits the limiting protrusion 23, so that the plug 20 cannot be easily removed from the functional cavity or cannot be actively removed from the functional cavity.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
