Description

Technical Field

[0001] This utility model relates to the field of external device connection technology, specifically to a quick docking structure for external devices. Background Technology

[0002] In the use of external devices (such as data transmission modules, power interfaces, industrial control components, etc.), the connection between devices is a key link to ensure the realization of functions. Currently, the connection structure of external devices on the market generally has many technical pain points:

[0003] First, some docking structures require simultaneous alignment of multiple non-coaxial positioning holes and plug ends, necessitating repeated adjustments of angle and position during operation. This results in lengthy docking times, low efficiency, and difficulty in meeting the needs of rapid installation or emergency connections. Second, the locking reliability is insufficient. Some structures rely solely on a single snap-fit ​​or friction for fixation, which can easily loosen or even detach under vibration or impact conditions, causing equipment connection interruptions and affecting data transmission stability or power supply continuity. Third, unlocking operations are complex. Some docking structures require tools for disassembly or multiple steps to unlock, causing inconvenience for later equipment maintenance, replacement, or disassembly. Fourth, versatility and adaptability are poor. Most docking structures are designed for specific equipment sizes or interface specifications, making them incompatible with different types of external devices, increasing user costs and selection difficulty. Fifth, the fitting precision of some structural components is insufficient. After docking, excessive gaps can cause wobbling, leading to component wear over time and shortening the service life of the docking structure.

[0004] In response, we proposed a quick docking structure for external devices. Utility Model Content

[0022] Example 1

[0023] like Figure 1-4 As shown, the quick docking structure for external devices of this utility model includes a male connector 1 and a female connector 2. The male connector 1 and the female connector 2 are respectively provided with locking mechanisms for docking with each other and locking after rotation.

[0024] The male connector 1 is provided with a locking component and a plug-in component for docking. The locking component, the plug-in component and the male connector 1 are coaxially distributed. The female connector 2 is provided with a locking component mating groove 203 that cooperates with the locking component, and a mating plug-in component driving component is rotatably provided on the female connector 2.

[0025] First, align the male connector 1 and female connector 2 coaxially, so that the locking parts and connectors coaxially distributed on the male connector 1 are aligned with the locking part mating groove 203 and the rotatably mounted mating connector drive of the female connector 2, respectively. Then, bring the male connector 1 and female connector 2 closer together along the coaxial direction, so that the locking part of the male connector 1 enters the locking part mating groove 203 of the female connector 2, and at the same time, the connector of the male connector 1 and the mating connector drive of the female connector 2 make contact. Next, rotate the male connector 1 and female connector 2 relative to each other along the coaxial direction. At this time, the locking mechanisms on both interact to lock them, and the mating connector drive of the female connector 2 engages with the connector of the male connector 1 as it rotates, so that the male connector 1 and female connector 2 are stably connected. If separation is required, rotate the male connector 1 and female connector 2 in the opposite direction to release the locking mechanism, and then separate them along the coaxial direction.

[0026] Furthermore, the locking component includes a locking component body 102 coaxially disposed on one side of the male connector 1, and a plurality of locking component protrusions 103 are arranged in a circumferential array on the outer periphery of the locking component body 102. The plug-in component includes a plug-in component body 104 disposed on the side of the locking component body 102 away from the male connector body 101, and a plurality of plug-in component grooves 105 are arranged in a circumferential array on the end of the plug-in component body 104 away from the locking component body 102.

[0027] Furthermore, the female head 2 includes a female head housing 201, a locking member mating groove 203 is formed on one side of the female head housing 201, the cross-section of the locking member mating groove 203 is the same as the combined cross-section shape of the locking member body 102 and the locking member protrusion 103, a housing communication channel 202 is formed in the female head housing 201 that communicates with the locking member mating groove 203, a mounting hole is formed on the side of the female head housing 201 away from the locking member mating groove 203, a driving member body 204 is rotatably arranged in the mounting hole, a plurality of driving member inner protrusions 205 are arranged in a circumferential array on the outer periphery of the driving member body 204 located in the locking member mating groove 203, and a plurality of driving member outer protrusions 206 are arranged in a circumferential array on the outer periphery of the driving member body 204 located outside the locking member mating groove 203;

[0028] The number of protrusions 205 in the drive component is the same as the number of grooves 105 in the connector;

[0029] Specifically, during the insertion and locking process, the male connector 1 and the female connector 2 are first aligned. The locking component body 102 on the male connector 1, which serves as a locking element and has several locking component protrusions 103 arranged circumferentially on its outer periphery, is aligned with the locking component mating groove 203 on one side of the female connector housing 201 in the female connector 2. This groove has a cross-sectional shape identical to the combined cross-sectional shape of the locking component body 102 and the locking component protrusions 103. Simultaneously, the insertion component main body on the male connector 1, located on one side of the locking component body 102 and circumferentially arranged with several insertion component grooves 105 on its outer periphery away from the male connector body 101, is aligned with the female connector body. The male connector 104 (i.e., the plug-in connector) is aligned with the male connector 1 and female connector 204, which are rotatably mounted in the mounting hole of the female connector housing 201 and located in the locking part mating groove 203. The male connector 1 and female connector 2 are then brought closer together along the coaxial direction, so that the locking part body 102 of the male connector 1, with the locking part protrusions 103, is inserted into the locking part mating groove 203 of the female connector 2 (initial positioning is achieved due to the matching cross-sectional shapes), while the plug-in connector body 104 extends into… The locking part 1 contacts the driving part body 204 within the locking part mating groove 203; then, the male head 1 and female head 2 rotate relative to each other along the coaxial direction. The driving part body 204 rotates synchronously with this rotation. The inner protrusion 205 of the driving part located within the locking part mating groove 203 engages with the insertion groove 105 of the insertion part body 104. Furthermore, the locking part body 102 and the locking part protrusion 103 interact with the locking mechanism of the female head 2 within the locking part mating groove 203 as they rotate, achieving locking. The driving part body 204 is located within the locking part... The outer protrusion 206 of the drive component outside the mating groove 203 rotates synchronously with the main body 204 of the drive component to assist in completing the rotation action, and finally makes the male head 1 and the female head 2 stably connected. If it is necessary to open, rotate the male head 1 and the female head 2 in the opposite coaxial direction, which will drive the main body 204 of the drive component to rotate in the opposite direction, so that the inner protrusion 205 of the drive component disengages from the groove 105 of the plug-in component, and the locking component main body 102 and the locking component protrusion 103 disengage from the locking component mating groove 203. Then, the male head 1 and the female head 2 can be separated from each other in the coaxial direction.

[0030] In summary, the locking and unlocking process of the male connector 1 and the female connector 2 is based on the precise matching and coaxial operation of key components: When locking, first align the locking body 102 (with locking protrusion 103, which is the locking component) and the connector body 104 (with connector groove 105, which is the connector) of the male connector 1 with the locking mating groove 203 (the cross-section of which matches the combined shape of the locking body 102 and the locking protrusion 103) and the driving body 204 (with the driving inner protrusion 205, which is the same number as the connector groove 105 and is rotated) of the female connector 2 along the coaxial direction so that the locking body 102 and the locking protrusion 103 are embedded in the locking mating groove. The slot 203 and the connector body 104 contact the drive body 204, and then rotate relative to each other, causing the drive body 204 to rotate, so that the inner protrusion 205 of the drive part engages with the connector groove 105, and the locking body 102 and the locking protrusion 103 are locked with the locking mechanism of the female head 2 (the outer protrusion 206 of the drive part assists in the rotation), thus achieving stable docking; when opening, the drive part rotates in the opposite direction along the same axis, causing the inner protrusion 205 of the drive part to disengage from the connector groove 105, and the locking body 102 and the locking protrusion 103 to disengage from the locking part engagement slot 203, and finally the parts separate along the same axis to complete the unlocking. The entire process relies on the matching of component structures and coaxial action to achieve efficient docking and separation.
