Description

Technical Field

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

[0002] Generally, in existing connectors, a crown spring is provided in the guiding hole of the female connector. When the guiding head of the male connector is inserted into the guiding hole of the female connector, the crown spring in the guiding hole will contact the surface of the guiding head through deformation for connection.

[0003] In related technologies, due to the shape limitations of the female connector and the male connector, the guiding head always inserts into the guiding hole in the same posture, that is, the contact points between the crown spring and the side wall of the guiding head are always at the same point.

[0004] However, after long-term plugging and unplugging use, when wear appears on the side wall of the guiding head and the surface coating falls off, and the coating falling-off part happens to be at the contact point between the guiding head 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 will increase significantly after long-term use is an urgent problem to be solved by those skilled in the art.

[0006] It should be noted that the above information disclosed in this background art part is only used to understand the background art of the concept of this application. Therefore, the above description is not considered as information of the prior art. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, in the drawings, the thickness of the components may be exaggerated or reduced in order to effectively describe the technical content.

[0026] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0027] like Figure 1 , Figure 2 As shown, at least one embodiment provides a connector, including: a female connector 1 and a male connector 2, the female connector 1 is provided with a plurality of guide holes 11, the male connector 2 is provided with a plurality of guide joints 21, 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.

[0028] like Figure 3 As shown, in some embodiments, a crown spring 12 is slidably disposed in each guide hole 11 , and the crown spring 12 is limited in the guide hole 11 and will not separate from the guide hole 11 .

[0029] In this embodiment, when the crown spring 12 is subjected to force, the crown spring 12 moves in the axial direction.

[0030] like Figure 5 As shown, in some embodiments, the crown spring 12 is annular, and the side wall in the middle is recessed inward. When the guide joint 21 is inserted into the crown spring 12, the guide joint 21 pushes the crown spring 12 to move axially due to the inward recess of the side wall of the crown spring 12. When the crown spring 12 moves to a limited position, the guide joint 21 squeezes the recess 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 be in good contact due to the recess of the side wall.

[0031] like Figure 4 As shown, in some embodiments, a plurality of “V”-shaped sub-grooves 131 are formed on the inner wall of the guide hole 11 , and the “V”-shaped sub-grooves 131 are arranged along the circumference of the guide hole 11 and are connected end to end and communicated to form a guide groove 13 .

[0032] like Figure 5As shown, in some embodiments, a guiding post 121 is provided on the outer wall of the crown spring 12, and the guiding post 121 is located within the guiding groove 13.

[0033] Specifically, when the guiding connector 21 is inserted into the guiding hole 11, the guiding connector 21 will push the crown spring 12 to move axially. At the same time, during the axial movement of the crown spring 12, the guiding post 121 will move along the "V"-shaped sub-groove 131, so that the crown spring 12 rotates by a certain angle.

[0034] In this embodiment, since the insertion action of the guiding connector 21 will drive the crown spring 12 to rotate, each time the guiding connector 21 is inserted, the contact position between the crown spring 12 and the guiding connector 21 is different from the previous time, thus avoiding the problem that when there is damage on the side wall of the guiding connector 21 and the damaged part is located at the contact position between the crown spring 12 and the guiding connector 21, the crown spring 12 will always be in contact with the damage, resulting in a significant increase in contact resistance.

[0035] As Figure 4 shown, in some embodiments, the "V"-shaped sub-groove 131 includes: a first guiding channel 131a and a second guiding channel 131b connected end to end; elastic members 131c are provided at the tails of the first guiding channel 131a and the second guiding channel 131b; optionally, the elastic members 131c can be but are not limited to elastic sheets.

[0036] In this embodiment, the guiding post 121 of the crown spring 12 will be within the "V"-shaped sub-groove 131; among them, during the insertion of the guiding connector 21, the guiding post 121 will move along the first guiding channel 131a until it crosses the elastic member 131c (crossing the elastic member 131c means entering the second guiding channel 131b, so that it will not move back during the next movement); during the extraction of the guiding connector 21, the guiding post 121 will move along the second guiding channel 131b until it crosses the elastic member 131c (crossing the elastic member 131c means entering the first guiding channel 131a of another "V"-shaped sub-groove 131); that is, each insertion and extraction action of the guiding connector 21 will cause the guiding post 121 to gradually move along the guiding groove 13 (move in the direction of the arrow in the figure), so as to drive the crown spring 12 to gradually rotate by a corresponding angle, and the rotation direction remains the same, thus avoiding the problem that the contact resistance increases significantly due to the constant contact position between the crown spring 12 and the guiding connector 21 and always being in contact with the damaged part.

[0037] As Figure 6 shown, in some embodiments, a spring 14 is provided within the guiding hole 11; among them, when the male connector 2 is pulled out from the female connector 1, the spring 14 pushes the crown spring 12 to move outward, so that the guiding post 121 moves along the second guiding channel 131b and crosses the elastic member 131c.

[0038] In this embodiment, the function of the spring 14 is as follows: when the guide connector 21 is pulled out, it helps the crown spring 12 to move outward and cross the corresponding elastic member 131c, and after the male and female connectors are disengaged, the crown spring 12 will not shake within the guide hole 11.

[0039] As Figure 2 shown, in some embodiments, a pressing boss 22 is provided on the guide connector 21.

[0040] In this embodiment, the front portion of the guide connector 21 is for insertion into the crown spring 12, and the presence of the pressing boss 22 can ensure that the crown spring 12 moves in place by pushing the crown spring 12 axially.

[0041] As Figures 1 to 3 shown, at least one embodiment provides a female connector, including: a plurality of guide holes 11 are formed on the female connector 1; a guiding 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 guiding post 121 is arranged on the outer wall of the crown spring 12, and the guiding post 121 is located in the guiding groove 13; wherein, when the male connector 2 is inserted into the female connector 1, the crown spring 12 is stressed to make the guiding post 121 move along the guiding groove 13 to rotate a corresponding angle.

[0042] In some embodiments, the guiding groove 13 includes: a plurality of "V"-shaped sub-grooves 131; each "V"-shaped sub-groove 131 is arranged circumferentially along the guide hole 11 and is connected end to end; the "V"-shaped sub-groove 131 includes: a first guiding channel 131a and a second guiding channel 131b that are connected end to end; elastic members 131c are arranged at the tails of both the first guiding channel 131a and the second guiding channel 131b; wherein, when the male connector 2 is inserted into the female connector 1, the guiding post 121 moves along the first guiding channel 131a and crosses the elastic member 131c.

[0043] In some embodiments, a spring 14 is arranged 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 to move outward, so that the guiding post 121 moves along the second guiding channel 131b and crosses the elastic member 131c.

[0044] At least one embodiment provides a plugging method for a connector, including: connecting the male connector 2 and the female connector 1 so that the guide connector 21 of the male connector 2 is inserted into the guide hole 11 of the female connector 1; by inserting the guide connector 21 into the guide hole 11, the crown spring 12 in the guide hole 11 rotates a corresponding angle to change the contact position between the guide connector 21 and the crown spring 12.

[0045] For the specific structure and implementation process of the connector, refer to the relevant discussions in the above embodiments, and details are not described herein again.

[0046] In summary, in the connector, the plugging method of the connector, and the female connector of the connector, by providing the crown spring 12 that can rotate during the insertion and extraction of the guide connector 21, the contact position between the guide connector 21 and the crown spring 12 is different each time, avoiding the problem that when the guide connector 21 is damaged, the contact resistance increases due to the unchanged contact position between the crown spring 12 and the guide connector 21.
