Detailed Description

The following detailed description and technical contents of the present invention are described with reference to the drawings, which are provided for reference and illustration purposes only and are not intended to limit the present invention.

Fig. 1 to fig. 3 are a schematic perspective view and an exploded schematic perspective view of a connector with a quick positioning structure according to the present invention. The invention relates to a connector with a quick positioning structure, which comprises a plug structure 1, wherein the plug structure 1 comprises a base 10, a terminal group 20, an inner sleeve 30, a positioning ring body 40 and an outer sleeve 50. The terminal set 20 and the inner sleeve 30 are assembled on the base 10, and the positioning ring 40 and the outer sleeve 50 are assembled outside the inner sleeve 30, so as to form the plug structure 1. The plug structure 1 is described in more detail below.

The terminal set 20 is disposed in the base 10. The terminal set 20 includes a terminal base 21 disposed on the base 10 and a plurality of conductive terminals 22 disposed in the terminal base 21. In addition, the terminal set 20 further includes a plurality of conductive wires 23 electrically connected to the conductive terminals 22 and an insulating sleeve 24 disposed outside the conductive wires 23. One end of the insulating sleeve 24 penetrates through the base 10 to connect with an electronic device.

It should be noted that, in practical implementation, the plug structure 1 can be directly disposed on a circuit board without the wires 23 and the insulating sheath 24. The base 10 is preferably made of an insulating material, but may be made of a metal material.

The inner sleeve 30 is fixed on the base 10 and the terminal set 20 is inserted through, and the positioning ring 40 is sleeved outside the inner sleeve 30. The positioning ring body 40 includes a ring piece 41, a plurality of elastic pieces 42 connected to the ring piece 41, and a plurality of hooks 43. The elastic pieces 42 are arranged at intervals and annularly arranged on the ring piece 41. The hooks 43 are correspondingly disposed on the elastic pieces 42. In the present embodiment, each of the hooks 43 is a nail-shaped hook.

Furthermore, the outer sleeve 50 includes an outer ring seat 51 disposed outside the inner sleeve 30 and an outer ring plate 52 connected to the outer ring seat 51. The outer ring plate 52 is provided with a plurality of slots 520 corresponding to the hooks 43. Therefore, the outer ring seat 51 can be sleeved outside the positioning ring body 40 and the hooks 43 can protrude out of the slots 520.

In an embodiment of the present invention, the inner wall of the outer ring seat 51 is formed with a plurality of hooks 511. In addition, a plurality of hook grooves 521 are formed at a bottom end of the outer ring plate 52. The outer ring seat 51 and the outer ring piece 52 are engaged with each other by the hooks 511 being engaged with the hooks 521. However, in practice, the outer ring seat 51 and the outer ring plate 52 may be integrally formed.

More specifically, one end of the inner sleeve 30 has a plurality of ribs 31 and a plurality of relief portions 32; the receding portions 32 are respectively formed between adjacent convex ribs 31, and at least one elastic sheet 42 (see fig. 1) penetrates through the receding portions 32. Accordingly, the elastic pieces 42 and the hooks 43 disposed thereon can slightly swing up and down in the receding portion 32. It should be noted that the ribs 31 block the rotation of the elastic pieces 42 when the inner sleeve 30 rotates, so that the ribs 31 prevent the inner sleeve 30 from rotating.

Fig. 4 is a plan side view of the positioning ring body of the present invention. Specifically, the positioning ring body 40 has an axial direction 400 and a horizontal plane 401 perpendicular to the axial direction 400; the hooks 43 are correspondingly disposed on the elastic pieces 42 and have not the same axial distance to the horizontal plane 401. In an embodiment of the present invention, the elastic pieces 42 respectively extend from the ring piece 41 to different heights, so that the hooks 43 thereon are disposed on the elastic pieces 42 in a manner that the axial distances to the horizontal plane 401 are one of unequal or partially equal, and therefore, the hooks 43 on the elastic pieces 42 can present different heights.

In this embodiment, the axial distance from the height of each elastic piece 42 to the horizontal plane 401 is partially equal, so that each hook 43 and the corresponding end of each elastic piece 42 are at the same distance and have different heights. However, in practical implementation, the heights of the elastic pieces 42 may be the same, but the hooks 43 and the corresponding ends of the elastic pieces 42 are arranged at different distances or at equal distances to present different heights.

Specifically, the plug structure 1 further includes a resilient latch set 60. The elastic locking set 60 includes a spring 61, a locking ring 62 and a C-shaped retaining ring 63. The arrangement of the spring 61, the latching ring 62 and the C-shaped retaining ring 63 is shown in FIG. 5 and described in detail later.

Fig. 5 is a partial sectional view of the plug structure of the present invention after assembly. As shown, the outer ring seat 51 is formed with a ring groove 510. The spring 61 is disposed in the annular groove 510, the detent ring 62 is abutted against one side of the annular groove 510, and the outer annular seat 51 can move relative to the detent ring 62.

In addition, the inner sleeve 30 is correspondingly provided with a locking groove 34 at the rear side of the locking ring 62. The C-shaped retaining ring 63 is engaged with the engaging groove 34 and abuts against one side of the engaging ring 62. Accordingly, the outer ring seat 51 can slightly move relative to the latching ring 62. In this embodiment, the outer ring seat 51 can move a distance d relative to the latching ring 62. The outer ring plate 52 connected to the outer ring seat 51 also moves with the outer ring seat 51 relative to the elastic plates 42.

Referring to fig. 6 and fig. 7, a schematic diagram of the connector with the quick positioning structure according to the present invention is shown. The plug structure 1 of the present invention can be quickly inserted into a receptacle structure 2. As shown in fig. 6, the connector with the quick-positioning structure of the present invention further includes a receptacle structure 2 for mating with the connector. The socket structure 2 includes a socket body 70 and a plurality of threads 71 formed in the socket body 70.

Notably, the inner sleeve 30 is formed with a plurality of tabs 33; on the other hand, the socket body 70 has a plurality of conductive posts 72 and a plurality of positioning slots 720 formed between the conductive posts 72. Accordingly, when the plug structure 1 and the socket structure 2 are plugged together, the plugging pieces 33 are correspondingly plugged into the positioning grooves 720.

Furthermore, referring to fig. 7, in an embodiment of the present invention, the socket structure 2 further includes a waterproof gasket 80 disposed in the socket body 70; the inner sleeve 30 of the plug structure 1 is inserted into the socket body 70 to abut against the waterproof gasket 80. Referring to fig. 8, the inner sleeve 30 is inserted into the socket body 70 such that the hooks 43 of the positioning ring 40 abut against the threads 71, thereby positioning the plug structure 1 in the socket structure 2 without being disengaged.

Please refer to fig. 8 and fig. 9, which are a partial sectional view of the connector with the quick positioning structure after plugging and a relative position diagram of the thread 71 and the hook 43 thereof, respectively. As shown in the partial cross-sectional view of fig. 8, the axial cross-section of the hooks 43 is substantially triangular, and the positions of the hooks 43 perpendicular to the axial direction 400 of the positioning ring body 40 are not equal, so that the ends of some of the hooks 43 will abut against the threads 71. Furthermore, after the inner sleeve 30 of the plug structure 1 is inserted into the socket body 70, the inner sleeve 30 will extend into the socket body 70 until it stops abutting against the waterproof gasket 80. At this time, in the plug structure 1, at least three hooks 43' of the hooks 43 protruding from the slots 520 of the outer sleeve 50 respectively abut against the threads 71 of the socket body 70.

Referring to FIG. 9, it shows the relative positions of the hook 43 of the plug structure 1 and the thread 71 of the socket structure 2 when the inner sleeve 30 stops advancing. The hooks 43 in fig. 9 are disposed on the elastic pieces 42 in a manner that the axial distances to the horizontal plane 401 are partially equal. As can be seen from the figure, the ends of at least three hooks 43 ' of the hooks 43 are exactly located on the spiral line 71 ', i.e. the hooks 43 ' are engaged on the thread 71 to achieve the mutual positioning effect of the plug structure 1 and the socket structure 2.

It should be noted that the waterproof gasket 80 is deformed by the pushing of the inner sleeve 30. When the waterproof gasket 80 is deformed, the inner sleeve 30 can further extend into the socket body 70, and further, the position of the hook 43 engaging the threads 71 can be changed. However, even if the position of the hooks 43 for engaging the threads 71 changes, at least three hooks 43 will engage the threads 71, so as to ensure the mutual positioning effect.

It should be noted that the hook 43 of the plug structure 1 of the present invention can be abutted against different types of threads, so that the socket structure 2 can be adapted to be abutted against the plug structure 1 when the specifications are different, thereby increasing the flexibility and practicability of the present invention in use.

Fig. 10 is a schematic diagram showing the connector with the quick positioning structure according to the present invention. The plug construction 1 of the invention can be quickly detached from the socket construction 2. As shown in the drawings, when the plug structure 1 is to be separated from the socket structure 2, a force is applied to the outer ring seat 51, so that the outer ring seat 51 moves toward the catch ring 62 and generates a displacement of a distance d, and the outer ring piece 52 moves along with the outer ring seat 51. At this time, the outer ring 52 presses the hooks 43 to move the elastic pieces 42 downward toward the relief portion 32 of the inner sleeve 30, and at this time, the hooks 43 disengage from the threads 71. Accordingly, the plug structure 1 can be easily separated from the socket structure 2.

Fig. 11 is a schematic view showing another relative position between the screw and the hook of the connector with the quick positioning structure of the present invention after plugging. In this embodiment, the hooks 43 are disposed on the elastic pieces 42 in a manner that the axial distances to the horizontal plane 401 are unequal. However, the hooks 43 still have at least three ends of the hooks 43 ' located on the spiral line 71 ', i.e. the hooks 43 ' are engaged with the threads 71 to position the plug structure 1 and the receptacle structure 2 with respect to each other.

Fig. 12 and fig. 13 show another embodiment of a plug structure and another embodiment of a positioning ring body according to the present invention, respectively. Referring to fig. 12, the plug structure 1a includes a base 10a, a terminal set 20a, an inner sleeve 30a, a positioning ring 40a and an outer sleeve 50 a. The main difference between this embodiment and the previous embodiment is the structure of the positioning ring 40a and the corresponding inner sleeve 30 a.

As shown in fig. 13, the positioning ring body 40a includes a ring piece 41a, a plurality of elastic pieces 42a and a plurality of hooks 43 a. The elastic pieces 42a are arranged at intervals and annularly arranged on the ring piece 41 a; the hooks 43a are correspondingly disposed on the elastic pieces 42 a. In the present embodiment, each of the hooks 43a is a tongue-shaped hook.

In the present embodiment, each of the elastic pieces 42a includes a connecting section 421a connected to the ring piece 41a and a hook section 422a provided with the hook 43 a. Specifically, the width of the connecting segment 421a is smaller than the width of the hook segment 422a, and the thickness of the connecting segment 421a is smaller than the thickness of the hook segment 422 a. Accordingly, the elastic piece 42a has a better deformation force, and the service life of the elastic piece 42a can be prolonged.

Referring to fig. 14 and 15, a partial cross-sectional view of another embodiment of the plug structure and a stress-bearing schematic view of another embodiment of the plug structure are shown, respectively. As shown in fig. 14, the inner sleeve 30a is fixed on the base 10a and the terminal set 20a is disposed through the inner sleeve 30a, and the positioning ring 40a is disposed outside the inner sleeve 30 a. In addition, the inner sleeve 30a has a plurality of relief portions 32a, at least one elastic piece 42a is inserted into the relief portion 32a, and the elastic piece 42a and the hook 43a disposed thereon can slightly swing up and down in the relief portion 32 a. The outer sleeve 50a includes an outer ring seat 51a and an outer ring plate 52 a.

It should be noted that, in the present embodiment, the inner sleeve 30a is formed with a bevel 321a at a front end of the receding portion 32 a; when the hook 43a is inserted into the receding portion 32a, one side of the hook 43a will abut against the inclined surface 321a, and the inclined surface 321a is disposed to enable the hook 43a to have better fixing and tensile strength.

Referring to fig. 15, when the outer ring seat 51a is pressed by a force, the outer ring seat 51a moves in the direction of the force, and at this time, the outer ring piece 52a presses the hooks 43a to move the elastic piece 42a in the relief portion 32a downward, and at this time, the hooks 43a are disengaged from the hooks to achieve the purpose of separation.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the present invention, but rather as an equivalent to the spirit of the present invention.
