[0001] The invention relates to a connector, in particular to a connector with a quick positioning structure and capable of quick docking. Background Art

[0002] Traditionally, cable connectors are mostly connected by quick-connect push-pull, rotary lock or screw thread tightening. However, the aforementioned rotary lock or screw thread tightening connection method takes up a lot of space and cannot be used in places with limited space. Although the quick-connect push-pull connection method is convenient, it is easy to loosen and separate when pulled or vibrated by external force, so the connection effect after connection cannot be guaranteed.

[0003] Furthermore, there are various types of plugs and sockets in the cable connectors currently on the market, but most of the plugs can only be matched with a single type of socket, which does not meet the high efficiency and multi-functional requirements of modern industry.

[0004] In view of this, the inventor has devoted himself to studying the above-mentioned prior art and has applied theoretical knowledge to try his best to solve the above-mentioned problems, which has become the goal of the inventor's improvement. Summary of the invention

[0005] One object of the present invention is to provide a connector with a quick positioning structure, wherein the plug structure is provided with hooks at different heights on the positioning ring body, and at least three hooks will abut against the threads of the socket structure, thereby allowing the plug structure to be quickly positioned in the socket structure and not to be disengaged.

[0006] Another object of the present invention is to provide a connector with a quick positioning structure, wherein the hook of the plug structure can be engaged with threads of different shapes. Therefore, when the specifications of the socket structure are different, it can still be applied to the docking plug structure, thereby increasing the flexibility and practicality of the present invention when in use.

[0007] In order to achieve the above-mentioned purpose, the present invention is a connector with a quick positioning structure, including a plug structure, which includes a base, a terminal group, an inner sleeve, a positioning ring body and an outer sleeve; wherein the terminal group is arranged in the base; the inner sleeve is fixed on the base and penetrated with the terminal group; the positioning ring body is sleeved outside the inner sleeve and has an axial direction and a horizontal plane perpendicular to the axial direction, the positioning ring body includes a ring plate, a plurality of elastic plates connecting the ring plates and a plurality of hooks, the plurality of elastic plates are arranged at intervals and arranged in a ring shape on the ring plate, the plurality of hooks are correspondingly arranged on the plurality of elastic plates and the axial distances to the horizontal plane are unequal or partially equal; the outer sleeve includes an outer ring seat arranged outside the inner sleeve and an outer ring plate connected to the outer ring seat, the outer ring plate is provided with a plurality of grooves corresponding to the hooks, the outer ring seat is sleeved outside the positioning ring body and the plurality of hooks protrude out of the plurality of grooves.

[0008] In order to achieve the above-mentioned purpose, the present invention is a connector with a quick positioning structure, which also includes a socket structure, which includes a socket body and a plurality of threads formed in the socket body, and the inner sleeve of the plug structure is inserted into the socket body so that the plurality of hooks are engaged with the plurality of threads.

[0009] Compared to the known technology, the plug structure of the connector with a quick positioning structure of the present invention has a positioning ring body, which has a plurality of elastic sheets arranged at intervals and in a ring shape, and a plurality of hooks at different heights are provided on the plurality of elastic sheets; when the plug structure and the socket structure are docked with each other, at least three hooks will abut against the threads of the socket structure, thereby achieving a quick and reliable positioning of the connector; in addition, since the hooks of the plug structure can abut against threads of different shapes, the flexibility and practicality of the present invention when in use can be increased.

DETAILED DESCRIPTION

[0026] 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.

[0027] Please refer to Figures 1 to 3The figures are respectively a three-dimensional schematic diagram of the appearance of a connector with a quick positioning structure of the present invention and a three-dimensional exploded schematic diagram in both sides. The present invention is a connector with a quick positioning structure, comprising a plug structure 1, the plug structure 1 comprising a base 10, a terminal group 20, an inner sleeve 30, a positioning ring body 40 and an outer sleeve 50. The terminal group 20 and the inner sleeve 30 are assembled on the base 10, and the positioning ring body 40 and the outer sleeve 50 are assembled outside the inner sleeve 30, thereby forming the plug structure 1. The plug structure 1 is described in more detail as follows.

[0028] The terminal set 20 is disposed in the base 10. The terminal set 20 includes a terminal base 21 disposed in the base 10 and a plurality of conductive terminals 22 disposed in the terminal base 21. In addition, the terminal set 20 also includes a plurality of wires 23 electrically connected to the conductive terminals 22 and an insulating sleeve 24 sleeved outside the wires 23. One end of the insulating sleeve 24 passes through the base 10 to connect an electronic device.

[0029] It should be noted that, in actual implementation, the plug structure 1 can be directly disposed on a circuit board without the wires 23 and the insulating sleeve 24. In addition, the base 10 is preferably made of insulating material, but can also be made of metal material.

[0030] The inner sleeve 30 is fixed on the base 10 and penetrates the terminal set 20. In addition, the positioning ring body 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 arranged on the elastic pieces 42. In this embodiment, each of the hooks 43 is a nail-shaped hook body.

[0031] Furthermore, the outer sleeve 50 includes an outer ring seat 51 disposed outside the inner sleeve 30 and an outer ring sheet 52 connected to the outer ring seat 51. The outer ring sheet 52 is provided with a plurality of slots 520 corresponding to the hooks 43. Thus, the outer ring seat 51 can be sleeved outside the positioning ring body 40 and the hooks 43 protrude out of the slots 520.

[0032] In one 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 bottom end of the outer ring piece 52 is formed with a plurality of hook grooves 521. The outer ring seat 51 and the outer ring piece 52 are combined by the hooks 511 being buckled in the hook grooves 521. However, in actual implementation, the outer ring seat 51 and the outer ring piece 52 may also be formed in one piece.

[0033] More specifically, one end of the inner sleeve 30 has a plurality of ribs 31 and a plurality of relief portions 32; the relief portions 32 are formed between adjacent ribs 31, and at least one elastic sheet 42 is inserted through the relief portion 32 (see Figure 1 As shown in FIG. 1 ). Accordingly, the elastic sheets 42 and the hooks 43 disposed thereon can slightly swing up and down in the yielding portion 32. It should be noted that when the inner sleeve 30 rotates, the ribs 31 will block the elastic sheets 42 from rotating. Therefore, the arrangement of the ribs 31 can prevent the inner sleeve 30 from rotating.

[0034] Please refer to Figure 4 , which is a planar side view of the positioning ring body in 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 arranged on the elastic sheets 42 and the axial distances to the horizontal plane 401 are not completely equal. In one embodiment of the present invention, the elastic sheets 42 extend from the ring sheet 41 to different heights respectively, so that the hooks 43 located thereon are arranged on the elastic sheets 42 in a manner such that the axial distances to the horizontal plane 401 are unequal or partially equal, so that the hooks 43 on the elastic sheets 42 can present a form of different heights.

[0035] It should be noted that in this embodiment, the axial distances from the height of each elastic sheet 42 to the horizontal plane 401 are partially equal, so each hook 43 and the end of each corresponding elastic sheet 42 maintain the same distance and present a form of different heights. However, in actual implementation, the heights of each elastic sheet 42 can be set to be the same, but each hook 43 and the end of each corresponding elastic sheet 42 are set to have different distances or be partially equal to present a form of different heights.

[0036] Specifically, the plug structure 1 further includes an elastic latch set 60. The elastic latch set 60 includes a spring 61, a latch ring 62 and a C-shaped buckle ring 63. The arrangement of the spring 61, the latch ring 62 and the C-shaped buckle ring 63 is described in detail in detail. Figure 5 shown and described in detail below.

[0037] Please continue to refer to Figure 5 , which is a partial cross-sectional view of the plug structure of the present invention after assembly. As shown in the figure, the outer ring seat 51 is formed with a ring groove 510. The spring 61 is arranged in the ring groove 510, the catch ring 62 abuts against one side of the ring groove 510, and the outer ring seat 51 can move relative to the catch ring 62.

[0038] In addition, the inner sleeve 30 is provided with a slot 34 corresponding to the rear side of the snap ring 62. The C-shaped retaining ring 63 is engaged in the slot 34 and abuts against one side of the snap ring 62. Accordingly, the outer ring seat 51 can move slightly relative to the snap ring 62. In this embodiment, the outer ring seat 51 can move a distance d relative to the snap ring 62. The outer ring sheet 52 connected to the outer ring seat 51 will also move relative to the elastic sheets 42 along with the outer ring seat 51.

[0039] Please refer to Figure 6 and Figure 7 As shown in the figure, they are respectively a schematic diagram of the plugging of the connector with a quick positioning structure of the present invention and a cross-sectional view after plugging. The plug structure 1 of the present invention can be quickly inserted into a socket structure 2. Figure 6 As shown, the connector with a quick positioning structure of the present invention further comprises a socket structure 2 for relative plugging. The socket structure 2 comprises a socket body 70 and a plurality of threads 71 ​​formed in the socket body 70 .

[0040] It is worth noting that the inner sleeve 30 is formed with a plurality of plug-in plates 33; on the other hand, the socket body 70 has a plurality of guide posts 72 and a plurality of positioning grooves 720 formed between the guide posts 72. Accordingly, when the plug structure 1 and the socket structure 2 are plugged into each other, the plug-in plates 33 will be correspondingly plugged into the positioning grooves 720.

[0041] Furthermore, please refer to Figure 7 As shown, in one 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 and stops on the waterproof gasket 80. Figure 8 As shown, the inner sleeve 30 is inserted into the socket body 70 so that the hook 43 of the positioning ring body 40 abuts against the threads 71, thereby positioning the plug structure 1 in the socket structure 2 and preventing it from coming out.

[0042] Please also refer to Figure 8 and Fig. 9 As shown in FIG. 1 , they are partial cross-sectional views of the connector with a quick positioning structure after plugging and schematic views of the relative positions of the thread 71 and the hook 43 of the connector. Figure 8As shown in the partial cross-sectional view, the axial section of the hook 43 is roughly triangular. In addition, the positions of the hooks 43 disposed on the axial direction 400 perpendicular to the positioning ring body 40 are not equal, and the ends of some hooks 43 will abut the thread 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 interior of the socket body 70 until it abuts the waterproof gasket 80. At this time, in the plug structure 1, among the several hooks 43 protruding from the slot 520 of the outer sleeve 50, at least three hooks 43' will abut the thread 71 of the socket body 70 respectively.

[0043] Please refer to Fig. 9 , which shows a schematic diagram of 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 moving forward. Fig. 9 The hooks 43 are arranged on the elastic sheets 42 in such a way 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' among the hooks 43 are exactly located on the spiral line 71', that is, the hooks 43' are locked on the thread 71 to achieve the effect of mutual positioning of the plug structure 1 and the socket structure 2.

[0044] It should be noted that the waterproof gasket 80 will be deformed after being pushed by the inner sleeve 30. When the waterproof gasket 80 is deformed, the inner sleeve 30 can be further extended into the socket body 70, and further, the position of the hook 43 that engages the threads 71 ​​will also change. However, even if the position of the hook 43 that engages the threads 71 ​​changes, at least three hooks 43 will still be engaged on the threads 71, so the mutual positioning effect can be ensured.

[0045] It should also be noted that the hook 43 of the plug structure 1 of the present invention can be engaged with threads of different shapes. Therefore, when the specifications of the socket structure 2 are different, it can still be suitable for docking with the plug structure 1, thereby increasing the flexibility and practicality of the present invention when in use.

[0046] Please refer to Fig.10 , which is a schematic diagram of the separation of the connector with a quick positioning structure of the present invention. The plug structure 1 of the present invention can be quickly separated from the socket structure 2. As shown in the figure, when the plug structure 1 is to be separated from the socket structure 2, force is applied to the outer ring seat 51, so that the outer ring seat 51 moves toward the latch ring 62 and generates a displacement of a distance d, and the outer ring sheet 52 moves with the outer ring seat 51. At this time, the outer ring sheet 52 presses the hooks 43 so that the elastic sheets 42 move downward toward the yielding portion 32 of the inner sleeve 30, and at this time, the hooks 43 are disengaged from the latch of the threads 71. Accordingly, the plug structure 1 can be easily separated from the socket structure 2.

[0047] Please refer to Fig.11 , which shows another schematic diagram of the relative positions of the threads and hooks of the connector with a quick positioning structure of the present invention after being plugged in. In this embodiment, the hooks 43 are arranged on the elastic sheets 42 in a manner that the axial distances to the horizontal plane 401 are unequal. However, the same thing is that the ends of at least three hooks 43' among the hooks 43 will be exactly located on the spiral line 71', that is, the hooks 43' will be locked on the threads 71 ​​so that the plug structure 1 and the socket structure 2 can achieve the effect of mutual positioning.

[0048] Please refer to Fig.12 and Fig.13 , which are another embodiment of the plug structure and another implementation of the positioning ring body of the present invention. Fig.12 As shown, the plug structure 1a includes a base 10a, a terminal set 20a, an inner sleeve 30a, a positioning ring 40a and an outer sleeve 50a. The main difference between this embodiment and the previous embodiment lies in the positioning ring 40a and the corresponding inner sleeve 30a structure.

[0049] like Fig.13 As shown, the positioning ring body 40a includes a ring piece 41a, a plurality of elastic pieces 42a and a plurality of hooks 43a. The elastic pieces 42a are arranged at intervals and annularly on the ring piece 41a; the hooks 43a are correspondingly arranged on the elastic pieces 42a. In this embodiment, each of the hooks 43a is a tongue-shaped hook piece.

[0050] In this embodiment, each of the elastic sheets 42a includes a connecting section 421a connected to the ring sheet 41a and a hook section 422a provided with the hook 43a. Specifically, the width of the connecting section 421a is smaller than the width of the hook section 422a, and the thickness of the connecting section 421a is smaller than the thickness of the hook section 422a. Accordingly, the elastic sheet 42a can have a better deformation force and increase the service life of the elastic sheet 42a.

[0051] Please refer to Fig.14 and 15 As shown in FIG. 1 , there are respectively a partial cross-sectional view of another embodiment of the plug structure of the present invention and a force diagram of another embodiment of the plug structure. Fig.14As shown, the inner sleeve 30a is fixed on the base 10a and penetrated by the terminal set 20a, and the positioning ring body 40a is sleeved outside the inner sleeve 30a. In addition, the inner sleeve 30a has a plurality of paving portions 32a, and the paving portions 32a are penetrated by at least one elastic sheet 42a. The elastic sheet 42a and the hook 43a disposed thereon can swing slightly up and down in the paving portions 32a. The outer sleeve 50a includes an outer ring seat 51a and an outer ring sheet 52a.

[0052] It is worth noting that in this embodiment, the inner sleeve 30a is formed with a slope 321a at a front end of the yielding portion 32a; when the hook 43a is inserted into the yielding portion 32a, one side of the hook 43a will press against the slope 321a. The setting of the slope 321a can make the hook 43a have better fixing and tensile resistance effects.

[0053] Please refer to Fig.15 As shown, when force is applied to the outer ring seat 51a, the outer ring seat 51a moves in the direction of the force. At this time, the outer ring sheet 52a will press the hooks 43a so that the elastic sheet 42a in the yielding portion 32a moves downward. At this time, the hooks 43a will disengage from the latch to achieve the purpose of separation.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the patent scope of the present invention. Other equivalent changes that apply the patent spirit of the present invention should all fall within the patent scope of the present invention.
