AI Technical Summary
Traditional crystal connectors are unstable in communication equipment and are prone to loosening or falling off due to vibration or pulling, affecting communication stability.
The fixed plate uses a retaining groove combined with the limiting structure of the crystal head spring, and the pressing part and limiting part of the rotating part form a double limiting to ensure that the crystal head is stable after insertion. When pulling out, the limiting part needs to be moved away from the crystal head, which increases the difficulty of operation and prevents accidental pulling.
It significantly improves the reliability and security of RJ45 connectors, reduces the probability of them falling off due to external force or vibration, and enhances the stability of the connection and the security of the system.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of communication engineering technology, specifically to a switch for communication engineering. Background Technology
[0002] In the construction and maintenance of communication engineering projects, RJ45 connectors are commonly used to connect network cables to communication equipment such as switches and routers to enable data or signal transmission. Conventional RJ45 connectors typically use spring clips to attach to the device interface, allowing for connection and disconnection simply by plugging and unplugging.
[0003] However, in practical applications, when traditional snap-fit connections are subjected to external forces such as vibration and pulling, the connection between the cable end and the switch is subjected to a large amount of external force, which affects the stability of the connection between the cable and the switch. This can easily lead to the RJ45 connector becoming loose or falling off, thus affecting communication stability. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a switch for communication engineering.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A communication engineering switch for connecting RJ45 connectors, comprising:
[0007] The switch body has one side for plugging in the RJ45 connector.
[0008] A fixing plate is fixed to the side of the switch body for plugging into the crystal head body. The side of the fixing plate near the crystal head body is provided with a retaining groove to limit the position of the crystal head body spring.
[0009] A rotating component is rotatably mounted on a fixed plate. The position of the rotating component matches the position of the crystal head body. It has a squeezing part that restricts the position of the crystal head body and a limiting part that facilitates the movement of the spring.
[0010] When the crystal head body is plugged into one side of the switch body, the crystal head body is squeezed by the limiting part to rotate the rotating part. After the rotating part rotates, the squeezing part is pressed against the side of the crystal head body away from the switch body.
[0011] Preferably, the aforementioned pressing part is located on the side of the fixed plate away from the switch body, the aforementioned limiting part is located in the retaining groove, and the aforementioned rotating part body is located on the side of the rotating part away from the switch body, which only rotates and tilts the limiting part under the action of gravity.
[0012] Preferably, the end of the limiting part away from the rotating part is inclined toward the switch body, and its inclination direction is configured to facilitate the crystal head body to squeeze the rotating part to rotate.
[0013] Preferably, when the aforementioned limiting part is fully raised, the protruding groove at the end away from the rotating part pushes the spring piece of the crystal head body out of the groove.
[0014] Preferably, the rotating member can rotate at an angle of 30° to 60°.
[0015] Preferably, the side of the aforementioned retaining groove is an arc surface tangent to the end of the spring piece of the crystal head body or a plane forming an acute angle with the spring piece of the crystal head body.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. By setting the retaining groove on the fixed plate and cooperating with the spring of the crystal head body for limiting, and combined with the rotating part structure with the pressing part and the limiting part, after the crystal head is inserted, the pressing part of the rotating part can automatically abut against the side of the crystal head away from the switch body, thus forming a double limiting structure, which significantly reduces the probability of the crystal head falling off due to external force or vibration, and improves the reliability of the insertion connection.
[0018] 2. The spring is released only by a toggle motion away from the RJ45 connector, creating an operation path opposite to the conventional plugging and unplugging method. This prevents unauthorized personnel from accidentally or arbitrarily removing the RJ45 connector, thus improving system security. Attached Figure Description

[0028] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0029] Example
[0030] like Figures 1-4 As shown, a communication engineering switch is used to plug in the crystal head body 12, including a switch body 11, a fixing plate 21 and a rotating part 22.
[0031] One side of the switch body 11 is used to plug in the crystal head body 12. The switch body 11 is used to plug in several crystal head bodies 12 for signal conversion.
[0032] In one embodiment, such as Figures 2-4 As shown, the fixing plate 21 is fixed to one side of the switch body 11 for inserting the crystal head body 12. The fixing plate 21 has a retaining groove 211 on the side near the crystal head body 12 to restrict the position of the spring contacts of the crystal head body 12. The fixing plate 21 is fixed to one side of the switch body 11 and is positioned close to the crystal head body 12. When the crystal head body 12 is inserted into the switch body 11, the spring contacts of the crystal head body 12 will be stuck in the retaining groove 211 of the fixing plate 21, so that the crystal head body 12 cannot be arbitrarily removed from the switch body 11. This structure can improve the protection effect of the connection between the crystal head body 12 and the switch body 11, and reduce the probability of removing the crystal head body 12 from the switch body 11 by increasing the difficulty of contacting the spring contacts. The side of the retaining groove 211 is an arc surface tangent to the end of the spring piece of the crystal head body 12 or a plane at an acute angle to the spring piece of the crystal head body 12, which improves the fit of the spring piece when it is engaged, enhances the limiting stability, prevents loosening caused by the spring piece sliding or misalignment, and improves the overall shock resistance and resistance to external interference.
[0033] In one embodiment, such as Figures 2-4As shown, the rotating component 22 is rotatably mounted on the fixed plate 21. The position of the rotating component 22 matches the position of the crystal head body 12. It has a pressing part 221 that restricts the position of the crystal head body 12 and a limiting part 222 that facilitates the movement of the spring clip. When the crystal head body 12 is inserted into one side of the switch body 11, the crystal head body 12 presses the rotating component 22 to rotate through the limiting part 222. After the rotating component 22 rotates, the pressing part 221 is close to the side of the crystal head body 12 away from the switch body 11. In the initial state, the pressing part 221 in the rotating component 22 is located below the snap-fit height of the plug-in interface on the switch body 11, so that it does not interfere with the crystal head body 12. The insertion path is such that the squeezing part 221 will not interfere with the insertion of the crystal head body 12; the height of the limiting part 222 overlaps with the snap-fit height of the plug interface on the switch body 11. The spring clip of the crystal head body 12 is squeezed by the squeezing part 221 to rotate the rotating part 22. During the snap-fit process, the rotating part 22 drives the squeezing part 221 to rotate until it is in a state of contact with the bottom of the crystal head body 12. After the crystal head body 12 is fully snapped into the switch body 11, the squeezing part 221 is snapped on the side of the crystal head body 12 away from the crystal head body 12. The squeezing part 221 restricts the position of the crystal head body 12 and reduces the probability of the crystal head body 12 falling off under the action of external force. If it is necessary to remove the RJ45 connector 12 from the switch body 11, the pressing part 221 needs to be pushed down to rotate the limiting part 222, pushing the spring of the RJ45 connector 12 out of the retaining groove 211, and then the RJ45 connector 12 can be removed. This method differs from the conventional method of removing the RJ45 connector 12 by pushing the pressing part 221 away from the RJ45 connector 12, and the direction of action is opposite, which increases the difficulty of operation for other personnel and reduces the probability that the RJ45 connector 12 will be removed by other personnel.
[0034] In one embodiment, such as Figures 2-4 As shown, the pressing part 221 is located on the side of the fixing plate 21 away from the switch body 11, the limiting part 222 is located in the retaining groove 211, and the main body of the rotating member 22 is located on the side of the rotating member 22 away from the switch body 11. It rotates and tilts the limiting part 222 only under the action of gravity. The pressing part 221 is located on the side of the fixing plate 21 away from the switch body 11 so that it will not interfere with the insertion action of the crystal head body 12. The limiting part 222 is set in the retaining groove 211, corresponding to the insertion direction of the crystal head body 12. The main body of the rotating member 22 is located on the side away from the switch body 11, forming a self-weight bias structure, so that it naturally returns to the position of the tilted limiting part 222 only under the action of gravity. This allows the rotating member 22 to maintain its initial tilted state when not subjected to external force, simplifying the structural design, avoiding interference from additional elastic components such as springs, and achieving reset by gravity, reducing costs and improving structural reliability.
[0035] In one embodiment, such as Figure 4As shown, the end of the limiting part 222 away from the rotating part 22 is inclined toward the switch body 11. Its inclined direction is configured to facilitate the crystal head body 12 to squeeze the rotating part 22 to rotate. During the insertion process, the crystal head body 12 can slide and squeeze the inclined surface, thereby driving the rotating part 22 to rotate smoothly. The rotating part 22 can be automatically responded without additional thrust, improving the user's insertion smoothness and enhancing the intelligence of the structural cooperation.
[0036] In one embodiment, such as Figures 2-4 As shown, when the limiting part 222 is fully tilted upwards, the protruding retaining groove 211 at the end away from the rotating member 22 pushes the spring piece of the crystal head body 12 out of the retaining groove 211. When the limiting part 222 is manually pushed upwards to the fully tilted state, the end away from the rotating member 22 can extend out of the top edge of the retaining groove 211, thereby pushing out the spring piece of the crystal head body 12 stuck therein. This achieves the goal that when pulling out the crystal head body 12, only the limiting part 222 needs to be pushed upwards to release the engagement between the spring piece and the retaining groove 211, avoiding forced pulling or damage to the crystal head structure, improving ease of use and component life. The rotating member 22 can rotate at an angle of 30° to 60°. This angle range allows the pressing part 221 of the rotating member 22 to not interfere with the crystal head body 12 initially, while controlling the structural dimensions and operating space, ensuring a compact structure while achieving reliable engagement and disengagement functions.
[0037] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
