Detailed Description

To further illustrate the various embodiments, the invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. Those skilled in the art will appreciate still other possible embodiments and advantages of the present invention with reference to these figures. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.

The present embodiment provides a docking device with an optimized guiding structure, which can be applied to a device that needs to be mated with each other to establish a physical connection, and generally has two terminals that are mated with each other, such as a mechanical mating of a fluid pipeline, an electrical connection of a signal line, and the like.

The invention will now be further described with reference to the accompanying drawings and detailed description.

Example 1:

referring to fig. 1, as a preferred embodiment of the present invention, there is provided a connector including a female plug 1 and a male plug 2, wherein the female plug 1 has a pin as a first connecting body, the male plug 2 has a socket as a second connecting body, and when the female plug 1 is mated with the male plug 2, the pin is inserted into the socket to complete electrical connection (substantial connection). The front end of the female plug 1 is provided with a guide cylinder 3, the guide cylinder 3 surrounds a pin of the female plug 1, and the male plug 2 can be inserted into the guide cylinder 3 and accurately inserted into the female plug 1 after being guided and corrected by the guide cylinder 3 so as to complete electric connection. Referring to fig. 2, showing a specific structure of the guiding cylinder 3, the guiding cylinder 3 is a substantially cylindrical structure, and the respective insertion ends of the female plug 1 and the male plug 2 are the respective front ends, so that the front opening of the guiding cylinder 3 has an end surface 33, the end surface 33 is obliquely cut on the cylinder body 31 (oblique to the axis of the guiding cylinder 3) so as to form an oblique first guiding slope, and at the lowest position (i.e. the lowest point of the first guiding slope) of the cylinder body 31 obliquely cut by the end surface 33, a positioning groove 32 is formed on the cylinder body 31, and the positioning groove 32 is rearwardly formed along the axial direction of the guiding cylinder 3, and the opening is communicated to the lowest position.

Referring to fig. 1 and 3, the male plug 2 includes a plug portion 21 located at the front end thereof, the plug portion 21 is substantially a rotating body structure, the male plug 2 has an axially linearly extending horizontal guiding column 5 at the outer periphery thereof, a roller 4 is rotatably connected to the end portion of the guiding column 5 at a position close to the front end of the male plug 2, and the width of the roller 4 is greater than the wall thickness of the guiding cylinder 3 (i.e., greater than the width of the end surface 33), so that the contact surface between the roller 4 and the end surface 33 is maximized, and the stability of the roller 4 rolling on the end surface 33 is ensured. The outer diameter of the roller 4 is slightly smaller than the groove width of the positioning groove 32 to ensure that the roller 4 can fall into the positioning groove 32, and meanwhile, the groove bottom of the positioning groove 32 is a curved surface matched with the outer circle of the roller 4. Referring to fig. 4, the shape of the guiding post 5 matches the shape of the positioning groove 3, and when the guiding post 5 falls into the positioning groove 32, the guiding post 5 is also inserted into the positioning groove 32, so that the circumferential positioning of the male plug 2 is more stable.

Referring to fig. 2 again, the mouth of the guiding cylinder 3 is further provided with a conical surface 34, the conical surface 34 is coaxial with the guiding cylinder 3, and gradually converges from the front to the back from the mouth of the guiding cylinder 3, so as to form an inclined second guiding slope, when the male plug 2 is inserted, if the axial direction is inclined with the female plug 1, the male plug can be gradually guided under the guidance of the conical surface 34, so as to ensure the accuracy of the male plug and the female plug in butt joint; the entrance of the positioning groove 32 is in the shape of a flared trumpet to form a flared opening for guiding the roller 4 to fall into the positioning groove 32, and the flared structure makes the roller 4 more easily positioned and simultaneously makes the movement of the roller 4 falling into the positioning groove 32 more stable and smooth.

The sizes of the roller 4 and the guide cylinder 3 in this embodiment can be designed according to actual situations, and under the basic requirement of male-female plug-in butt joint, the sizes of the inner diameter and the outer diameter of the guide cylinder 3, the wheel width of the roller 4, and the like are reasonably designed to enable the roller 4 to contact the end face 33, which can be realized by those skilled in the art on the basis of the technology provided by this embodiment.

The mechanism of action of this example is as follows: when the male plug 2 is butted with the female plug 1, the plug part 21 is firstly inserted into the guide cylinder 3, under most conditions in the butting process, the roller 4 on the outer peripheral side of the plug part 21 is contacted with the first guide slope formed by the end face 33 and forms a rolling pair with the end face 33, because the end face 33 is inclined, the male plug 2 or the female plug 1 is twisted in a randomly selected direction in the inserting process, the roller 4 can gradually roll under the guide of the end face 33 and finally falls into the positioning groove 32 at the lowest position on the cylinder body 31, and the roller 4 serves as a positioning pin to complete the circumferential positioning of the male plug 2. When the male plug 2 is inserted, the axial direction is inclined with respect to the female plug 1, and the male plug can be gradually aligned by being guided by the tapered surface 34.

In this embodiment, because the end face 33 forms a first oblique guiding slope, the positioning groove 32 is disposed at the lowest position of the first guiding slope, so that the male plug 2 can be inserted into the guiding cylinder 3 at any angle, and can be guided by the end face 33 to roll obliquely into the positioning groove 32 on the basis of keeping the insertion direction, when the male plug 2 and the female plug 1 are butted by a user, the butt joint can be performed at will, without aligning the male plug with the female plug, but by means of the structure of the guiding cylinder 3 and the rolling cylinder 4, the male plug 2 is automatically aligned and corrected in the inserting process, the first guiding slope and the second guiding slope guide the male plug 2 to perform angle twisting and axial correction, thereby greatly simplifying the flow of the butt joint work, improving the work efficiency of the butt joint of the connector, and improving the use experience.

In this embodiment, the roller 4 is used as a smooth rolling surface to be in rolling fit with the end surface 33 and is guided by the end surface 33, in other embodiments, the roller 4 may also be a structure (such as a fixed cylinder which cannot rotate) with only a smooth sliding surface, and the positioning pin structure on the male plug is slid into the positioning groove on the female plug by the sliding fit between the surfaces, but compared with this, the movement is smoother in the process of butt joint of the male plug and the female plug by adopting the rolling fit scheme; meanwhile, the roller 4 can be replaced by other rolling devices, such as a bull's eye universal ball and the like, but the cost of using the roller 4 is lower, the contact surface between the roller and the end surface 33 is larger, and the applicability is higher; the roller 4 is therefore preferred in this embodiment.

It should be noted that the roller 4 (positioning pin) and the guiding cylinder 3 are additional structures of the male and female connectors, and in other embodiments, the roller 4 (positioning pin) may be disposed on the female connector 1 and the guiding cylinder 3 may be disposed on the male connector 2.

In the present embodiment, an electrical connector is taken as an example to illustrate one embodiment, but the male and female end docking structure formed by the guide cylinder 3 and the positioning pin (roller 4) in the present embodiment can also be used in other docking structures, such as a mechanical docking device.

Example 2:

this embodiment is similar to embodiment 1, and provides a connector, which includes a female plug 1 and a male plug 2 ', the female plug 1 has the same structure as the female plug 1 in embodiment 1, and the male plug 2' is slightly different from the male plug 2 in embodiment 1, referring to fig. 5, the difference is that: the male plug 2 'in this embodiment does not have the structure of the guide post 5, but the roller 4 is rotatably mounted on the outer peripheral surface of the plug portion 21'. Likewise, the roller 4 is configured as a positioning pin and can roll down into the positioning groove 32 under the guidance of the guide cylinder 3.

The roller 4 is a positioning pin structure matched with the end face 33 of the guide cylinder 3, is arranged on the periphery of the male plug to realize a circumferential limiting function, and is not limited by the existence of the guide column 5. Those skilled in the art will appreciate that the arrangement of the roller 4 (positioning pin) can be adjusted according to the application and the specific structure based on the combination of embodiment 1 and the present example.

It should be noted that the plug portion 21' may be rotatable, and in embodiment 1, the plug portion 21 and the male plug 2 are not rotatable integrally, so that when the male plug 2 is inserted into the female plug 1, it is necessary to slightly twist the male plug 2 or the female plug 1 (the movement is smooth under the guidance of the guide cylinder 3) to realize the guide movement of the roller 4. In this embodiment, referring to fig. 5, there is also shown the operation limiting ring 6 and the operation lever 7 in the male plug 2 ', the operation limiting ring 6 is a collar structure sleeved on the plug portion 21 ', and the operation lever 7 is a handle structure connected to the operation limiting ring 6 and substantially grippable, the plug portion 21 ' can rotate relative to the operation limiting ring 6 and the operation lever 7, that is, when the male plug 2 ' is inserted into the female plug 1, the operation lever 7 and the operation limiting ring 6 are held in a radial direction, and the plug portion 21 ' rotates relative to the operation limiting ring 6 and the operation lever 7 under the cooperation of the roller 4 and the guide cylinder 3 until the roller 4 slides into the positioning groove 32. In an example operation, the operating lever 7 may be omitted and the insertion of the male plug 2' may be performed by acting directly on the operating limit ring 6.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
