Description

Technical Field

[0001] The present invention belongs to the technical field of electrical components, and specifically relates to a connecting device, and more particularly to a connector, a method for plugging the connector, and a female connector of the connector. Background Art

[0002] In conventional connectors, a crown spring is disposed in the guide hole of the female connector. When the guide pin of the male connector is inserted into the guide hole of the female connector, the crown spring in the guide hole deforms to contact the surface of the guide pin to achieve connection.

[0003] In the related art, due to the shape restrictions of the female connector and the male connector, the conductive joint is always inserted into the conductive hole in the same posture, that is, the contact point between the crown spring and the side wall of the conductive joint is always located at the same point.

[0004] However, after long-term plugging and unplugging, when the side wall of the conductor joint is worn and the surface coating falls off, and the coating falls off at the contact point between the conductor joint and the crown spring, the contact resistance will increase significantly.

[0005] Therefore, how to solve the technical problem that the contact resistance between the female connector and the male connector increases significantly after long-term use is urgently needed to be solved by those skilled in the art.

[0006] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. In addition, in the drawings, the thickness of components may be exaggerated or reduced in order to effectively describe the technical content.

[0033] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0034] like Figure 1 、 Figure 2 As shown, at least one embodiment provides a connector, including: a female connector 1 and a male connector 2, wherein the female connector 1 is provided with a plurality of guide holes 11, and the male connector 2 is provided with a plurality of guide joints 21, and when the male connector 2 is connected to the female connector 1, the corresponding guide joints 21 are inserted into the corresponding guide holes 11.

[0035] like Figure 3 As shown, in some embodiments, a crown spring 12 is slidably disposed in each guide hole 11 . The crown spring 12 is limited in the guide hole 11 and will not fall out of the guide hole 11 .

[0036] In this embodiment, when the crown spring 12 is subjected to force, the crown spring 12 moves in the axial direction.

[0037] like Figure 5 As shown, in some embodiments, the crown spring 12 is annular, and the side wall in the middle is concave inward. When the guide joint 21 is inserted into the crown spring 12, the inward concave side wall of the crown spring 12 causes the guide joint 21 to push the crown spring 12 to move axially. When the crown spring 12 moves to a limited position, the guide joint 21 squeezes the concave part of the crown spring 12 and continues to move to complete the insertion. At this time, the crown spring 12 and the guide joint 21 can make good contact due to the concave side wall.

[0038] like Figure 4As shown, in some embodiments, a plurality of V-shaped sub-grooves 131 are formed on the inner wall of the guide hole 11 . The V-shaped sub-grooves 131 are arranged along the circumference of the guide hole 11 and are connected end to end to form a guide groove 13 .

[0039] like Figure 5 As shown, in some embodiments, a guide post 121 is provided on the outer wall of the crown spring 12 , and the guide post 121 is located in the guide groove 13 .

[0040] Specifically, when the guide joint 21 is inserted into the guide hole 11 , the guide joint 21 pushes the crown spring 12 to move axially. Simultaneously, during the axial movement of the crown spring 12 , the guide post 121 moves along the V-shaped sub-slot 131 , thereby rotating the crown spring 12 by a certain angle.

[0041] In this embodiment, since the insertion of the conductive joint 21 causes the crown spring 12 to rotate, the contact position between the crown spring 12 and the conductive joint 21 is different each time the conductive joint 21 is inserted. This avoids the problem of the crown spring 12 always being in contact with the damaged sidewall of the conductive joint 21, which would significantly increase the contact resistance if the damaged sidewall is located at the contact position between the crown spring 12 and the conductive joint 21.

[0042] like Figure 4 As shown, in some embodiments, the "V"-shaped sub-groove 131 includes: a first guide channel 131a and a second guide channel 131b connected end to end; the tails of the first guide channel 131a and the second guide channel 131b are both provided with elastic members 131c; optionally, the elastic member 131c can be but is not limited to a spring sheet.

[0043] In this embodiment, the guide post 121 of the crown spring 12 is within the V-shaped sub-groove 131. During insertion of the conductive head 21, the guide post 121 moves along the first guide channel 131a until it passes over the elastic member 131c (passing over the elastic member 131c means entering the second guide channel 131b, preventing it from returning to its original position during the next insertion). During removal of the conductive head 21, the guide post 121 moves back along the second guide channel 131b until it passes over the elastic member 131c (passing over the elastic member 131c means entering the first guide channel 131a of the other V-shaped sub-groove 131). In other words, each insertion and removal of the conductive head 21 causes the guide post 121 to gradually move along the guide groove 13 (in the direction of the arrow in the figure), thereby causing the crown spring 12 to gradually rotate by a corresponding angle, and the rotation direction remains consistent, thereby avoiding the problem of a significant increase in resistance caused by the crown spring 12 and the conductive head 21 always being in contact with the damaged area due to the unchanged contact position.

[0044] like Figure 6As shown, in some embodiments, a spring 14 is provided in the guide hole 11; wherein, when the male connector 2 is pulled out of the female connector 1, the spring 14 pushes the crown spring 12 outward, so that the guide column 121 moves along the second guide channel 131b and passes over the elastic member 131c.

[0045] In this embodiment, the function of the spring 14 is to help the crown spring 12 move outward and over the corresponding elastic member 131 c when the conductive joint 21 is pulled out, and to prevent the crown spring 12 from shaking in the conductive hole 11 after the male and female connectors are pulled out.

[0046] like Figure 2 As shown, in some embodiments, a pressing boss 22 is provided on the conductive joint 21 .

[0047] In this embodiment, the front portion of the guide joint 21 is used to be inserted into the crown spring 12 , and the presence of the pressing boss 22 can ensure that the crown spring 12 moves into position by pushing the crown spring 12 to move axially.

[0048] like Figures 1 to 3 As shown, at least one embodiment provides a female connector, including: a plurality of guide holes 11 are formed on the female connector 1; a guide groove 13 is formed on the inner wall of the guide hole 11; a crown spring 12 is slidably arranged in the guide hole 11, and a guide column 121 is provided on the outer wall of the crown spring 12, and the guide column 121 is located in the guide groove 13; wherein, when the male connector 2 is inserted into the female connector 1, the crown spring 12 is subjected to force to cause the guide column 121 to move along the guide groove 13 to rotate a corresponding angle.

[0049] In some embodiments, the guide groove 13 includes: a plurality of "V"-shaped sub-grooves 131; each "V"-shaped sub-groove 131 is arranged along the circumference of the guide hole 11 and is connected end to end; the "V"-shaped sub-groove 131 includes: a first guide channel 131a and a second guide channel 131b connected end to end; the tails of the first guide channel 131a and the second guide channel 131b are both provided with an elastic member 131c; wherein, when the male connector 2 is inserted into the female connector 1, the guide column 121 moves along the first guide channel 131a and passes over the elastic member 131c.

[0050] In some embodiments, a spring 14 is disposed in the guide hole 11 ; when the male connector 2 is pulled out of the female connector 1 , the spring 14 pushes the crown spring 12 outward, so that the guide post 121 moves along the second guide channel 131 b and passes over the elastic member 131 c .

[0051] At least one embodiment provides a method for plugging a connector, comprising: connecting a male connector 2 to a female connector 1 so that a conductive joint 21 of the male connector 2 is inserted into a conductive hole 11 of the female connector 1; and rotating a crown spring 12 of the conductive hole 11 by inserting the conductive joint 21 into the conductive hole 11 to change a contact position between the conductive joint 21 and the crown spring 12.

[0052] Regarding the specific structure and implementation process of the connector, please refer to the relevant discussion in the above embodiments and will not be repeated here.

[0053] In summary, the connector, the connector plugging method, and the female connector of the connector are provided with a crown spring 12 that can rotate during the plugging and unplugging process of the conductive joint 21, so that the contact position between the conductive joint 21 and the crown spring 12 is different each time, thereby avoiding the problem of increased contact resistance caused by the unchanged contact position of the crown spring 12 and the conductive joint 21 when the conductive joint 21 is damaged.

[0054] Herein, when it is mentioned that a first component is located on a second component, this may mean that the first component may be directly formed on the second component or a third component may be interposed between the first component and the second component.

[0055] As used herein, when an element or layer is referred to as being "located on," "engaged to," "connected to," "attached to," or "coupled to" another element or layer, it may be directly located on, engaged, connected, attached to, or coupled to the other element or layer, or there may be intervening elements or layers. Conversely, when an element is referred to as being "directly on," "directly engaged to," "directly connected to," "directly attached to," or "directly coupled to" another element or layer, there may be no intervening elements or layers. Other words used to describe the relationship between elements should be interpreted in a similar manner (e.g., "between" versus "directly between," "adjacent" versus "directly adjacent," etc.). As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0056] Herein, example embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings.
