Description

Technical Field

[0001] The invention relates to a connector docking structure, in particular to a cable connector docking structure for transmitting power or electrical signals. Background Art

[0002] The existing cable connector mainly achieves the purpose of transmitting power and / or electrical signals by plugging a first connector connected to a plurality of first cables and a second connector connected to a plurality of second cables. In order to prevent the unexpected separation of the cable connector and interruption of power or electrical signals, the first connector and the second connector are stably connected by means of quick-connect push-pull method, rotation lock method, or screw thread tightening engagement.

[0003] However, in the above-mentioned docking methods, although the quick-connect push-pull operation method can quickly and conveniently separate the two connectors, it cannot ensure the connection effect after docking, especially under the condition of external pulling or vibration. Although the rotating lock or screw tightening operation methods can ensure the reliable docking effect of the two connectors, they cannot achieve the effect of quick disassembly, and there is still inconvenience in use.

[0004] In view of this, the inventors have devoted themselves to research and applied theories to improve and solve the above-mentioned deficiencies, and finally proposed a reasonable design of the present invention that effectively improves the above-mentioned deficiencies. Summary of the invention

[0005] One of the purposes of the present invention is to provide a cable connector docking structure having both stable locking and quick release effects.

[0006] To achieve the above-mentioned purpose, the present invention provides a cable connector docking structure, including a first connector and a second connector. The first connector includes a first docking portion, a plurality of plug-in terminals arranged in the first docking portion, and an external threaded portion arranged on the outer peripheral surface of the first docking portion. The second connector includes a second docking portion, a plurality of plug-in holes arranged in the second docking portion, a locking sleeve arranged outside the second docking portion, a slot formed between the locking sleeve and the second docking portion, a positioning ring sleeved on the locking sleeve, a plurality of latches arranged between the positioning ring and the locking sleeve at intervals, and a snap-on quick-release ring detachably locked to the locking sleeve. The first docking portion corresponds to the insertion slot, and each plug-in terminal is plugged into each plug-in hole. The snap-on quick-release ring rotates to press each latch, and each internal threaded portion of each latch engages with the external threaded portion of the first docking portion.

[0007] In a specific embodiment, a plurality of pressing parts are convexly provided at intervals on the inner wall of the buckle quick release ring, and each latch is provided corresponding to each pressing part, and each latch has an inclined surface and a raised part connected to the inclined surface. Each pressing part rotates to press each raised part from each inclined surface. The locking sleeve is provided with a plurality of locking holes for accommodating each latch, and the positioning collar has two connecting strips for limiting the displacement of each latch and a plurality of connecting pieces connected to each connecting strip, so as to effectively limit the relative movement of each latch in each locking hole, so that each pressing part can press each raised part correspondingly.

[0008] After the first connector and the second connector are electrically connected to each other, the buckle quick release ring is rotated at an angle, for example, clockwise, so that each pressing portion correspondingly presses the raised portion of each latching member. The internal threaded portion of each latching member will correspondingly engage the external threaded portion of the first docking portion, so that the first docking portion and the second docking portion are locked. During this operation, the stopper portion of the buckle quick release ring will pass over and abut against the raised spring sheet to prevent the buckle quick release ring from rotating and disengaging from each latching member, thereby causing the first docking portion and the second docking portion to be accidentally loosened.

[0009] In a specific embodiment, when the first connector and the second connector need to be disassembled or separated, the quick-release ring only needs to be rotated in the opposite direction (counterclockwise) to separate the internal threaded portion of each latch from the external threaded portion of the first connector, thereby quickly detaching the first connector and the second connector.

[0010] In another specific embodiment, the fastening quick release ring includes at least one hook fastened to the flange of the second joint, a receiving space formed between the flange and each pressing part, and an elastic component sleeved in the receiving space, wherein the fastening quick release ring can move relative to the locking sleeve along the direction of a second rod. When the fastening quick release ring moves toward the flange to compress the elastic component, each pressing part of the fastening quick release ring quickly separates from the protrusions of each locking member, so that the internal thread part is separated from the external thread part, so that the first joint can be separated from the second joint, achieving a quick release effect.

[0011] The present invention also has the following beneficial effects: when the first connector and the second connector are plugged together, the protrusions of the latching parts can be effectively pressed by the pressing parts to achieve a stable screw-fastening or locking effect. When the first connector and the second connector are to be separated, the buckle quick-release ring can achieve the purpose of quick release or quick disassembly of the first connector and the second connector by rotating or moving horizontally.

DETAILED DESCRIPTION

[0023] The detailed description and technical contents of the present invention are described as follows with reference to the accompanying drawings. However, the accompanying drawings are only provided for reference and description and are not intended to limit the present invention.

[0024] See also Figures 1 to 4As shown, the present invention provides a cable connector docking structure, including a first connector 1 and a second connector 2. The cable connector referred to herein is to respectively connect one or more cables (not shown) using the first connector 1 and the second connector 2, and then electrically couple each other to achieve the purpose of transmitting power and / or signals. However, the first connector 1 and the second connector 2 can also be applied to different technical fields such as pneumatic connection tools, and are not limited thereto.

[0025] The first connector 1 comprises a first docking portion 11, a plurality of plug terminals 12 disposed in the first docking portion 11, and an external threaded portion 13 formed on the outer peripheral surface of the first docking portion 11. The second connector 2 comprises a second docking portion 21, a plurality of plug holes 22 disposed in the second docking portion 21, a locking sleeve 23 disposed outside the second docking portion 21, a slot 24 formed between the locking sleeve 23 and the second docking portion 21, a positioning collar 25 sleeved on the locking sleeve 23, a plurality of latching members 26 disposed between the positioning collar 25 and the locking sleeve 23 at intervals, and a snap-on quick-release ring 27 detachably locked to the locking sleeve 23.

[0026] When the first connector 1 and the second connector 2 are plugged into each other, the first docking portion 11 is correspondingly inserted into the slot 24, and each plug-in terminal 12 is plugged into each plug-in hole 22. In particular, a guide block 14 is provided on the inner wall of the first docking portion 11 adjacent to each plug-in terminal 12, and a guide groove 29 is formed on the second docking portion 21 corresponding to the guide block 14, so that the first docking portion 11 can be inserted into the second docking portion 21 in a predetermined direction to avoid mis-plugging.

[0027] One end of the first connector 1 of this embodiment is also connected to a first rod 15 of the first docking portion 11, and one end of the second connector 2 is connected to a second rod 30 of the second docking portion 21. The first rod 15 and the second rod 30 are respectively in the shape of round rods, and a convex pattern (not shown) is formed on part of the surface of the second rod 30 to facilitate the user to hold it. One or more cables (not shown) are respectively connected to the first rod 15 and the second rod 30, and the power supply or signal is connected or disconnected by connecting or disconnecting the first docking portion 11 and the second docking portion 21.

[0028] like Figures 1 to 4In the illustrated embodiment, the inner wall of the buckle quick release ring 27 is provided with a plurality of pressing parts 271 and at least one stopper 276 at intervals, wherein the stopper 276 is located between two of the pressing parts 271. Each latch 26 is provided corresponding to each pressing part 271, and each latch 26 has an inclined surface 262 and a raised part 263 connected to the inclined surface 262. Each pressing part 271 of the buckle quick release ring 27 can be rotatably slid from each inclined surface 262 to each raised part 263, so that each internal thread part 261 of each latch 26 is pressed and engaged with the external thread part 13 of the first docking part 11, thereby achieving a tightening effect of the first joint 1 and the second joint 2.

[0029] The shape of each pressing portion 271, the stop portion 276 and each protrusion 263 of this embodiment is, for example, a bump, a block or other suitable shape to achieve the effect of pressing or stopping. The buckle quick release ring 27 is hollow and has a through hole 272 formed therein and is sleeved on the lock sleeve 23. Before the buckle quick release ring 27 is assembled on the lock sleeve 23, it also includes a positioning ring 25 sleeved on the lock sleeve 23.

[0030] The locking sleeve 23 is provided with a plurality of locking holes 231 for accommodating the latching members 26 respectively. The positioning collar 25 has two connecting strips 251 for limiting the left-right displacement (axial direction) of the latching members 26 and a plurality of connecting pieces 252 connected to the connecting strips 251. The latching members 26 can move up and down (radially) relative to the external threaded portion 13 between the connecting strips 251 and the slots 24. Each connecting piece 252 has at least one protruding spring piece 253 and at least one positioning hole 254. The stopper 276 can rotatably resist the protruding spring piece 253 to prevent the quick release ring 27 from rotating, which will be described in detail later.

[0031] The lock sleeve 23 is provided with a positioning block 232 corresponding to the positioning hole 254, so that the positioning block 232 is engaged with the positioning hole 254, so that the positioning collar 25 is positioned on the outer circumferential surface of the lock sleeve 23. The two side edges of each latch 26 are respectively provided with a sheet 264 along the direction of each connecting strip 251, and the lock sleeve 23 is respectively formed with a positioning groove 233 corresponding to each sheet 264, so that each latch 26 can accurately return to its original position corresponding to each positioning groove 233 when moving radially relative to each lock hole 231.

[0032] The number of the latching members 26 and the locking holes 231 of this embodiment is preferably three, and the appearance profile of each latching member 26 is preferably a circular arc plate to engage with the external threaded portion 13 of the first docking portion 11. Each latching member 26 is also formed with two transverse grooves 265 corresponding to each connecting strip 251, so that the movement of each latching member 26 relative to each locking hole 231 is more certain and reliable. The positioning collar 25 made by metal stamping and bending can effectively limit the radial and axial displacement of each latching member 26 in each locking hole 231, so that each pressing portion 271 of the quick release ring 27 can achieve a correct, reliable and fast effect when rotating and pressing each protrusion 263.

[0033] In addition, please refer to Figure 6 and Figure 7 As shown, the second connector 2 also has a flange 28 vertically connected to the locking sleeve 23. The fastening quick release ring 27 includes at least one hook 273 of the fastening flange 28, and an accommodation space 274 formed between the flange 28 and each pressing portion 271, wherein the hook 273 can limit the fastening quick release ring 27 from moving toward the first connector 1. The end surface of the locking sleeve 23 is provided with a plurality of stop blocks 234 at intervals, wherein each stop block 234 is arranged in the axial direction corresponding to the position of each locking hole 231 to limit the rotation angle of the fastening quick release ring 27.

[0034] The buckle quick release ring 27 is formed with a plurality of notches 275 corresponding to each stopper 234. The size of each notch 275 is larger than the size of each stopper 234, so that the rotation angle of the buckle quick release ring 27 is limited. In this embodiment, the rotation angle of the buckle quick release ring 27 is approximately between 60 and 90 degrees. The position of each stopper 234 is substantially corresponding to the center of each locking hole 231, that is, aligned with the raised portion 263 of each latch 26.

[0035] The following further describes how the docking structure of the present invention can be quickly disassembled or separated. Figures 5 to 7 As shown, after the first connector 1 and the second connector 2 are electrically plugged into each other, the buckle quick release ring 27 is rotated by an angle, for example, clockwise, so that each pressing portion 271 correspondingly presses the raised portion 263 of each latching member 26. The internal thread portion 261 of each latching member 26 will correspondingly engage the external thread portion 13 of the first docking portion 11, so that the first docking portion 11 and the second docking portion 21 can achieve a stable locking effect. It should be noted that when the buckle quick release ring 27 is rotated, the stopper portion 276 will pass over and abut against the raised spring sheet 253 to prevent the buckle quick release ring 27 from rotating and disengaging from each latching member 26, thereby causing the first docking portion 11 and the second docking portion 21 to be accidentally loosened.

[0036] Please refer to Figure 8As shown, when the first connector 1 and the second connector 2 need to be disassembled or separated, the quick-release ring 27 only needs to be rotated in the opposite direction (counterclockwise) to separate the internal threaded portion 261 of each latch 26 from the external threaded portion 13 of the first connector 1, so that the first connector 1 and the second connector 2 can be quickly separated. At this time, the positioning collar 25 can effectively limit the displacement of each latch 26 so as to perform the next locking operation.

[0037] In addition, please refer to Fig. 9 As shown, another quick release operation method is also provided. The present embodiment also includes an elastic component 31 which is sleeved in the accommodating space 274. The elastic component 31 referred to herein is preferably a compression spring or other suitable elastic component. When the buckling quick release ring 27 moves toward the direction of the flange 28 (i.e., the second rod body 30) to compress the elastic component 31, each pressing portion 271 of the buckling quick release ring 27 is separated from the raised portion 263 of each latching member 26. The internal threaded portion 261 of each latching member 26 will be separated from the external threaded portion 13, so that the first connector 1 can be separated from the second connector 2 to achieve a quick release effect. When the user releases the buckling quick release ring 27, the elastic component 31 can provide an elastic force to restore the buckling quick release ring 27 to its initial position, such as Figure 8 shown.

[0038] Therefore, when the first connector 1 and the second connector 2 are plugged together, the pressing portions 271 of the buckle quick release ring 27 can effectively press the raised portions 263 of the buckle members 26 to achieve a stable locking or engagement effect. When the first connector 1 and the second connector 2 are to be separated, the buckle quick release ring 27 can achieve the purpose of quick release or quick disassembly of the first connector 1 and the second connector 2 by rotating or moving horizontally.

[0039] In summary, the embodiments disclosed herein should be considered to illustrate the present invention rather than to limit the present invention. The scope of the present invention should be defined by the appended claims and their legal equivalents, and should not be limited to the foregoing description.
