Description

Technical Field

[0001] This utility model relates to the field of electronic connector technology, specifically to an angle-adjustable circular connector. Background Technology

[0002] Connectors, also known as plugs, are small electronic components that are indispensable in modern life. Simply put, they are devices that provide quick connection and disconnection for the ends of wires. They mainly serve to connect circuits and transmit signals, and are widely used in various electronic devices.

[0003] Most current circular connectors do not have angle adjustment functionality. Therefore, some people have come up with the idea of ​​joining the cable inlet housing and the plug end together to achieve angle adjustment. For example, the invention patent with publication number CN116661071B specifically discloses an angle-adjustable circular connector.

[0004] However, in actual use, it is found that the above-mentioned circular connector mainly achieves angle adjustment through ball joint, but no limiting structure is set for it. This makes it easy for the ball joint to move due to external factors during use, causing the angle to shift and affecting its normal use. Utility Model Content

[0005] The purpose of this invention is to provide an angle-adjustable circular connector to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an angle-adjustable circular connector, comprising a cable inlet housing and a connecting cylinder, wherein the cable inlet housing is provided with a cable guide tube and a tapered tail sleeve, the connecting cylinder is rotatably connected to the end of the cable guide tube, the end of the connecting cylinder is provided with a plug-in housing, an external toothed ring is fixed to the side of the connecting cylinder, and a limiting mechanism is provided to the side of the cable guide tube.

[0007] The limiting mechanism includes a fixed plate, a movable plate, insert teeth, a connecting rod, a positioning block, and a spring. The fixed plate is fixed to the cable guide cylinder, the movable plate is located below the fixed plate, the insert teeth are fixed below the movable plate, and the insert teeth are inserted into the tooth groove of the outer toothed ring to limit the connecting cylinder. The connecting rod is fixed above the movable plate, and the connecting rod passes through the fixed plate and is connected to the positioning block. The spring is sleeved on the outside of the connecting rod, and both ends of the spring are connected to the fixed plate and the movable plate, respectively. By moving the movable plate upward, when the insert teeth on the movable plate disengage from the outer toothed ring, the limitation on the connecting cylinder is released, and the cable housing can be rotated to adjust its angle. The elastic force of the spring is used to re-insert the insert teeth into the tooth groove of the outer toothed ring to limit the connecting cylinder again. The spring can also be replaced with other elastic elements such as an elastic steel plate.

[0008] Preferably, the conical tail sleeve is provided with an elastic sealing ring, which is mainly used to compress the cable and restrict the cable.

[0009] Preferably, the plug-in housing is provided with conductive terminals for plugging into an external electronic connector, and the cable entering the cable housing is connected to the conductive terminals after passing through the cable inlet tube and the connecting tube.

[0010] Preferably, the movable plate is provided with a hand position, which is mainly to facilitate the staff to hold the movable plate.

[0011] Preferably, the cable inlet housing and the cable guide tube, the cable guide tube and the connecting tube, and the connecting tube and the plug-in housing are interconnected to enable cable threading.

[0012] Preferably, the positioning block and the connecting rod are fixed with screws to achieve a detachable connection, thereby enabling the restriction mechanism to be disassembled.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features a hinged connection between the connecting cylinder and the wire guide cylinder. When the angle needs to be adjusted, simply rotate the connecting cylinder or the wire guide cylinder to achieve the angle adjustment. The connecting cylinder is restrained by inserting the teeth on the limiting mechanism into the outer toothed ring, preventing the connecting cylinder and the wire guide cylinder from shifting due to external forces, thus improving the practicality of this connector.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Please see Figure 1-4 This utility model provides a technical solution: an angle-adjustable circular connector, including a cable inlet housing 1 and a connecting cylinder 2. The cable inlet housing 1 is provided with a cable guide cylinder 101 and a tapered tail sleeve 102. The connecting cylinder 2 is rotatably connected to the end of the cable guide cylinder 101. The end of the connecting cylinder 2 is provided with a plug-in housing 3. An external toothed ring 201 is fixed on the side of the connecting cylinder 2. A limiting mechanism 4 is provided on the side of the cable guide cylinder 101.

[0024] Furthermore, the limiting mechanism 4 includes a fixed plate 401, a movable plate 402, a toothed pin 403, a connecting rod 404, a positioning block 405, and a spring 406. The fixed plate 401 is fixed to the wire guide 101, the movable plate 402 is located below the fixed plate 401, the toothed pin 403 is fixed below the movable plate 402, and the toothed pin 403 is inserted into the tooth groove of the outer toothed ring 201 to limit the connecting cylinder 2. The connecting rod 404 is fixed above the movable plate 402, and the connecting rod 404 passes through the fixed plate 401 and is connected to the positioning block 405. Spring 406 is sleeved on the outside of connecting rod 404, and both ends of spring 406 are connected to fixed plate 401 and movable plate 402 respectively. By pushing movable plate 402 upward, when the insert tooth 403 on movable plate 402 is disengaged from outer tooth ring 201, the restriction of connecting cylinder 2 is removed, and cable housing 1 can be rotated to adjust its angle. The elastic force of spring 406 is used to re-insert insert tooth 403 into the tooth groove of outer tooth ring 201 to re-restrict connecting cylinder 2. Spring 406 can also be replaced by elastic steel plate or other elastic elements.

[0025] Furthermore, an elastic sealing ring 103 is provided inside the conical tail sleeve 102. The elastic sealing ring 103 is mainly used to squeeze the cable and restrict the cable.

[0026] Furthermore, the plug-in housing 3 is provided with a conductive terminal 301, which is used to plug into an external electronic connector, and the cable entering the cable housing 1 is connected to the conductive terminal 301 after passing through the cable inlet tube and the connecting tube 2.

[0027] Furthermore, the movable plate 402 is provided with a hand position 4021, which is mainly to facilitate the staff to hold the movable plate 402.

[0028] Furthermore, the cable inlet housing 1 is interconnected with the cable guide tube 101, the cable guide tube 101 with the connecting tube 2, and the connecting tube 2 with the plug-in housing 3 to enable cable threading.

[0029] Furthermore, the positioning block 405 and the connecting rod 404 are fixed with screws to achieve a detachable connection, thereby enabling the separation of the limiting mechanism 4.

[0030] In summary, when the angle of this connector needs to be adjusted, simply move the movable plate 402 towards the fixed plate 401 by hand. This causes the movable plate 402 to move the connecting rod 404, which then acts as a positioning element. Simultaneously, the movable plate 402 compresses the spring 406, causing it to deform and contract. Once the insert teeth 403 on the movable plate 402 exit from the grooves on the outer toothed ring 201, the restriction on the connecting cylinder 2 can be lifted. Then, the connecting cylinder 2 or the cable inlet housing 1 can be rotated directly to achieve angle adjustment. After adjustment, release the movable plate 402. As the spring 406 is no longer under pressure, it pushes the movable plate 402 back, causing the insert teeth 403 to insert into the corresponding grooves on the outer toothed ring 201, thus re-restricting it.

[0031] It is worth noting that the entire device is controlled by a master control button. Since the device matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
