Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically, to a cable-out rotating structure and a XLR connector. Background Technology

[0002] Connectors are joints used for quick connection of wires. Some connectors need to be installed inside electronic devices and connected to corresponding circuit boards via wires. In use, only one matching connector needs to be mated with the connector on the electronic device. Currently, the cable exits the connector in the axial direction of the connector. However, some precision electronic devices are small in size and have limited internal space, therefore requiring the cable to be bent 90 degrees and exit from one side. Chinese utility model patent CN 220857049 U discloses a bendable waterproof connector that allows the cable to be bent 90 degrees after exiting. However, to ensure the stability of the connector itself and the connection, once the connector is fixed to the electronic device, the cable's bending direction is a fixed value, which is not conducive to adjusting the exit direction according to the actual internal space of the electronic device. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model first provides a cable exiting rotating structure, including a connector base and a tail shell. The tail shell is located at the tail of the connector base and is rotatably connected to the connector base. The cable of the connector base extends out from the tail of the connector base. The tail shell communicates with the interior of the connector base, and a cable exiting hole is provided on the outer wall of the tail shell. The cable on the connector base passes through the cable exiting hole, and the cable exiting hole is adapted to drive the cable to bend to change the cable exiting direction.

[0004] Optionally, a flexible protective element is provided at the outlet hole, which is adapted to wrap the cable located at the outlet hole.

[0005] Optionally, the outer wall of the flexible protective member is fixedly provided with a plug strip, and the wall of the outlet hole is provided with a plug groove, and the plug strip is adapted to be inserted into the plug groove.

[0006] Optionally, an elastic ring is provided between the connector base and the tail shell, the elastic ring is connected to the connector base or the tail shell, and the two sides of the elastic ring abut against the connector base and the tail shell respectively.

[0007] Optionally, the outer peripheral wall of the elastic ring is exposed to air, and the elastic ring is black, red, or blue.

[0008] Optionally, the connector base has an installation groove at one end near the tail shell, and one end of the tail shell is inserted into the installation groove and engaged with and rotatably connected to the connector base.

[0009] Optionally, a snap-fit ​​foot is fixedly provided at one end of the tail shell near the connector base, and a snap-fit ​​ring groove is provided on the groove wall of the mounting groove to cooperate with the snap-fit ​​foot. The snap-fit ​​foot is adapted to rotate circumferentially within the snap-fit ​​ring groove.

[0010] Optionally, an arc-shaped piece is fixedly provided at one end of the tail shell near the connector base, and the outer peripheral wall of the arc-shaped piece abuts against the groove wall of the mounting groove.

[0011] Optionally, the length of the arc-shaped piece is greater than the length of the snap-fit ​​leg.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] 1. After the connector base is fixed, the user can rotate the tail shell at any angle to adjust the direction of the cable outlet according to the actual space size and cable outlet situation. It can be used in a variety of different narrow spaces, with a wide range of applications and convenient cable outlet direction adjustment.

[0014] 2. The setting of the elastic ring can provide a certain damping force when the tail shell rotates, which can limit the degree of freedom of the tail shell when rotating relative to the connector base, so that the tail shell is not easy to rotate on its own after the cable outlet direction is adjusted, thus changing the cable outlet direction.

[0015] 3. When electronic devices need to connect to multiple connector bases, the color of the elastic ring can quickly and intuitively indicate which connector base needs to be connected to the target circuit, improving the ease of identification during installation.

[0016] 4. After the cable passes through the outlet hole, the flexible protective component can protect the cable located in the outlet hole, making it less likely for the cable to come into contact with the hole wall and cause stress concentration, which could lead to cable sheath damage or cable breakage, thereby improving the life of the cable and connector.

[0017] 5. During assembly, simply insert the tail shell into the mounting slot and position the snap-fit ​​feet in the snap-fit ​​ring slot. Assembly is simple and quick, improving production efficiency.

[0018] In addition, this utility model provides a XLR connector, including the cable exit rotation structure as described above.

[0019] Compared with the prior art, the advantages of the XLR connector described in this utility model and the above-mentioned cable exit rotation structure compared with the prior art are the same, and will not be repeated here. Attached Figure Description

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-4 This application will be described in further detail.

[0026] In a first aspect, this utility model embodiment provides a wire-out rotating structure, referring to... Figure 1 and Figure 2 The cable exiting rotating structure includes a connector base 1 and a tail shell 2. The cable on the connector base 1 extends from its tail end for connection to a circuit board. The tail shell 2 is located at the tail end of the connector base 1, engaging and rotating with it. The axis of the connector base 1 coincides with the axis of the tail shell 2, and the tail shell 2 rotates relative to the connector base 1 about its own axis. The tail shell 2 is internally connected to the connector base 1, and an exit hole 21 is provided on its outer wall. The exit hole 21 is internally connected to the tail shell 2, allowing the cable on the connector base 1 to pass through it. The exit hole 21 is adapted to bend the cable to change its exit direction. Users can rotate the tail shell 2 to adjust the cable exit direction as needed, adapting to various confined spaces. This makes it widely applicable and the exit direction adjustment convenient.

[0027] The connector base 1 can be a XLR audio three-pin connector, an XLR audio five-pin connector, an HDMI connector, a USB connector, a Type-C connector, or an RJ45 connector; and the connector base 1 can be a male connector or a female connector. In this embodiment, the connector base 1 is preferably a female connector of an XLR audio three-pin connector for illustration.

[0028] Reference Figure 2 and Figure 3The connector base 1 has a mounting groove 11 at one end near the tail housing 2, through which the cable on the connector base 1 will pass. The tail housing 2 has a groove 22 at one end near the connector base 1, which communicates with the mounting groove 11 to allow the cable to enter. The outer wall of the cable outlet 21 is perpendicular to the end of the tail housing 2 with the groove 22, allowing the cable to bend at a 90-degree angle after passing through the groove 22 and exiting the cable outlet 21. In other embodiments, the two side walls of the tail housing 2 with the groove 22 and the cable outlet 21 may not be perpendicular, but rather form an obtuse or acute angle depending on the internal space of the corresponding electronic device.

[0029] In this embodiment, the cable exit hole 21 is preferably a U-shaped hole, meaning that the side of the cable exit hole 21 closest to the connector base 1 penetrates the tail shell 2. This reduces mold opening costs during production. A flexible protective element 23 is provided at the cable exit hole 21, which is suitable for wrapping the cable located at the cable exit hole 21. In this embodiment, the flexible protective element 23 is preferably made of silicone material. In another embodiment, the flexible protective element 23 can also be made of pearl cotton. The side of the flexible protective element 23 closest to the connector base 1 is flush with the side of the tail shell 2 closest to the connector base 1, thus ensuring aesthetics. A through hole is provided in the middle of the flexible protective element 23, allowing the cable to pass through the through hole. In this way, the flexible protective element 23 can protect the cable located at the cable exit hole 21, preventing the cable from contacting the hole wall of the cable exit hole 21 and causing stress concentration, which could lead to cable sheath damage or cable breakage.

[0030] Reference Figure 2 and Figure 3 The flexible protective component 23 has an integrally formed insertion strip 231 on its outer peripheral wall. An insertion groove 211 is formed on the wall corresponding to the cable outlet hole 21. The insertion strip 231 is suitable for insertion into the insertion groove 211, ensuring a stable connection between the flexible protective component 23 and the tail shell 2. This insertion method also makes the assembly of the flexible protective component 23 more convenient. In another embodiment, the flexible protective component 23 may not have the insertion strip 231; instead, it may be bonded to the tail shell 2 with adhesive.

[0031] Combination Figure 2 Reference Figure 3 and Figure 4The tail shell 2 has two integrally formed snap-fit ​​feet 24 at one end near the connector base 1, which are evenly spaced circumferentially. The two snap-fit ​​feet 24 are adapted to be inserted into the mounting groove 11 and snap-fitted into the connector base 1, allowing for rotatable connection. Specifically, the mounting groove 11 has a snap-fit ​​ring groove 12 on its wall, the axis of which coincides with the axis of the connector base 1. After the two snap-fit ​​feet 24 are inserted into the mounting groove 11, they can be inserted into the snap-fit ​​ring groove 12, allowing the tail shell 2 to snap-fit ​​into the connector base 1 in the axial direction. However, since the snap-fit ​​ring groove 12 is an annular groove, the two snap-fit ​​feet 24 can rotate circumferentially within the snap-fit ​​ring groove 12, thereby allowing the tail shell 2 to rotate circumferentially relative to the connector base 1, thus adjusting the cable outlet direction.

[0032] The tail shell 2, with its snap-fit ​​support 24, also features an integrally formed arc-shaped piece 25 at one end. This arc-shaped piece 25 is suitable for insertion into the mounting groove 11. The outer diameter of the arc-shaped piece 25 is the same as the groove diameter of the mounting groove 11. After insertion, the outer periphery of the arc-shaped piece 25 abuts against the groove wall, increasing the contact area between the tail shell 2 and the connector base 1 and improving the stability of the snap-fit ​​connection. The length of the arc-shaped piece 25 extending away from the tail shell 2 is longer than the length of the snap-fit ​​support 24 extending away from the tail shell 2. During assembly, the arc-shaped piece 25 can first enter the mounting groove 11, guiding the snap-fit ​​support 24 and improving assembly convenience.

[0033] Combination Figure 2 Reference Figure 3 and Figure 4 Additionally, a raised ring 13 is integrally formed on one side of the connector base 1 where the mounting groove 11 is formed. The mounting groove 11 is located inside the raised ring 13. The outer diameter of the raised ring 13 is smaller than the outer diameter of the connector base 1. An elastic ring 14 is fitted on the raised ring 13. Since the rubber ring itself has a large deformation capacity and friction force, it is preferred to use a rubber ring for the elastic ring 14 in this embodiment. However, in another embodiment, the elastic ring 14 can be made of pearl cotton material. After the tail shell 2 is connected to the connector base 1, the side of the elastic ring 14 near the connector base 1 contacts and abuts against the connector base 1, and the side of the elastic ring 14 near the tail shell 2 abuts against the tail shell 2. Since the elastic ring 14 is a rubber ring, it can provide a certain damping force when the tail shell 2 rotates, which can limit the degree of freedom of the tail shell 2 when rotating relative to the connector base 1, so that the tail shell 2 is not easy to rotate on its own after the cable outlet direction is adjusted, thus changing the cable outlet direction. In another embodiment, the raised ring 13 can be set on the side of the tail shell 2 near the connector base 1, so that the elastic ring 14 is located on the tail shell 2.

[0034] The outer peripheral wall of the elastic ring 14 is exposed to air. The elastic ring 14 can be black, red, blue, brown, orange, or green. When an electronic device needs to connect multiple connector bases 1, the color of the elastic ring 14 can quickly and intuitively indicate that the connector base 1 needs to be connected to the target circuit. In this embodiment, the elastic ring 14 is preferably black.

[0035] The implementation principle of the cable exit rotation structure in this application embodiment is as follows: the cable on the connector base 1 can be bent at a 90-degree angle after exiting the cable exit hole 21, making it suitable for cable routing in confined spaces. When the connector base 1 is installed on the electronic device, the user can rotate the tail shell 2 at any angle to adjust the direction of the cable exit according to the actual space size and cable exit situation. The elastic ring 14 provides a certain damping force when the tail shell 2 rotates, which can limit the degree of freedom of the tail shell 2 relative to the connector base 1, making it difficult for the tail shell 2 to rotate on its own and change the cable exit direction after the cable exit direction is adjusted. At the same time, when the electronic device needs to connect multiple connector bases 1, the color of the elastic ring 14 can quickly and intuitively indicate that the connector base 1 needs to be connected to the target circuit.

[0036] Secondly, another embodiment of this utility model provides a XLR connector, which is equipped with the cable exit rotation structure in the first aspect, so that the XLR connector can rotate the tail shell at any angle to adjust the direction of the cable exit according to the actual space size and cable exit situation, and can be used in a variety of different narrow spaces.
