[0004] Therefore, there is an urgent need for a plug connector with a new structure in the market to solve the problems of clamping failure and contact failure of the plug connector in the prior art after long-term insertion and removal. CONTENT OF THE INVENTION
[0005] The pin plug connector provided by the embodiments of the present disclosure can solve the problems of clamping failure and contact failure of the plug connector in the prior art after long-term insertion and removal.

[0008] The female connector has a recessed receiving jack.
[0009] The snap spring is arranged in the receiving jack.
[0010] The deformation clamping piece is arranged in the receiving jack and close to the bottom end of the receiving jack.
[0011] When the pin plug is inserted into the receiving jack, the snap spring and the deformation clamping piece can limit and fix the pin plug in the radial direction, respectively.
[0012] In an implementation, the snap spring and the deformation clamping piece are respectively provided with a receiving cavity extending in the depth direction of the receiving jack.
[0013] When the pin plug is inserted into the receiving cavity, the clamping spring and the deformed clamping member are deformed along the radial direction of the pin plug and exert a clamping force along the radial direction.
[0014] In an embodiment, the deformed clamping member is a clamping cylinder with a gap in the peripheral wall.
[0015] The pin plug can be tightly inserted into the receiving cavity inside the clamping cylinder, and the peripheral wall of the clamping cylinder is deformed and expanded to abut against the inner hole wall of the receiving hole.
[0016] In an embodiment, the gap is linear or helical along the axial direction of the clamping cylinder.
[0017] In an embodiment, the outer wall of the clamping cylinder is further provided with a protruding structure.
[0018] When the peripheral wall of the clamping cylinder is deformed and expanded, the protruding structure is fixedly abutted against the inner hole wall of the receiving hole.
[0019] In an embodiment, the protruding structure is a hemispherical protruding head, and multiple hemispherical protruding heads are arranged on the outer wall of the clamping cylinder.
[0020] In an embodiment, one end of the deformed clamping member abuts against the clamping spring, and the other end abuts against the bottom end of the receiving hole.
[0021] When the pin plug is inserted into the receiving hole, the clamping spring and the deformed clamping member can exert a pushing force on each other along the depth direction of the receiving hole.

[0025] In an embodiment, the clamping spring includes a mounting cylinder and a deformed spring.

[0027] The deformed spring has an inwardly protruding arch-shaped portion, and the arch-shaped portion can be flattened by the pin plug.
[0028] In an embodiment, multiple deformed springs are arranged.
[0029] The plurality of deformation springs are arranged in a ring array around the center of the snap spring piece.
[0030] Compared with the prior art, the technical scheme provided by the embodiments of the present disclosure has the following advantages:
[0031] When the pin plug connector is inserted and connected, the female connector is limited and clamped by the snap spring piece and the deformation clamping piece in the jack, which can respectively limit and clamp the pin plug in the male connector. Through the two clamping modes, the stability and reliability of the insertion and connection of the male connector can be fully ensured.
[0032] Moreover, when the pin plug in the male connector is disassembled and pulled out, the deformation clamping piece and the snap spring piece can respectively correspond to the recovery of deformation, avoiding the sudden decrease of resistance in the disassembly and pulling-out process of the pin plug, so as to improve the smoothness of the disassembly and pulling-out of the pin plug in the male connector.

[0044] In order to make the purpose, features and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present disclosure.
[0045] The embodiments of the present disclosure will be described in detail below with reference to the drawings.
[0046] In combination with Figure 1 And Figure 2 As shown in the drawings, the embodiments of the present disclosure provide a pin header connector, which includes a male connector 1, a female connector 2, a clamping spring member 3 and a deformation clamping member 4; the male connector 1 has a pin header 11 arranged protrudingly; the female connector 2 has a receiving hole 21 arranged recessively; the clamping spring member 3 is arranged in the receiving hole 21; the deformation clamping member 4 is arranged in the receiving hole 21 and close to the bottom end of the receiving hole 21; wherein when the pin header 11 is inserted into the receiving hole 21 correspondingly, the clamping spring member 3 and the deformation clamping member 4 can limit and fix the pin header 11 along the radial direction respectively.
[0047] The pin header connector can be specifically but not limitedly applied to the power connection connector in the mainboard of an electronic device, and the use process is described and illustrated by taking this as an example.
[0048] When the pin header connector is in use, first, the pin header 11 in the male connector 1 is gradually inserted into the receiving hole 21 in the female connector 2, and in the process, the pin header 11 will be inserted into the clamping spring member 3 and the deformation clamping member 4 in the receiving hole 21 in turn, and make the clamping spring member 3 and the deformation clamping member 4 elastically deform respectively, so that the pin header 11 will be preliminarily limited and fixed in the receiving hole 21 by the elastic clamping force of the deformation of the clamping spring member 3, and after the pin header 11 is further inserted into place, the deformation clamping member 4 can further exert the deformation force on the radial direction of the pin header 11, so as to finally realize the function of limiting and fixing the pin header 11 in the receiving hole 21 along the radial direction.
[0049] Compared with the way that the female connector in the prior art radially clamps the pin by a spring in the jack, the pin plug connector provided by the embodiment of the present disclosure can limit and clamp the pin plug 11 in the male connector 1 by the spring member 3 and the deformed clamping member 4 in the jack 21 when the pin plug connector is inserted and connected, and the stability and reliability of the insertion of the male connector 1 can be fully ensured by the two clamping ways, and when the pin plug 11 in the male connector 1 is disassembled and pulled out, the deformed clamping member 4 and the spring member 3 can correspondingly restore the deformation, so that the resistance in the disassembly and pulling-out process of the pin plug 11 is not suddenly reduced, and thus the smoothness of the disassembly and pulling-out of the pin plug 11 in the male connector 1 can be improved.
[0050] In summary, the pin plug connector provided by the embodiment of the present disclosure can realize twice clamping and limiting of the pin plug 11, effectively avoid the problems of clamping failure and poor contact of the pin plug 11 after multiple insertion and pulling-out, and also avoid sudden reduction of the resistance in the disassembly and pulling-out process of the pin plug 11 and improve the smoothness of the disassembly and pulling-out of the pin plug 11.
[0051] In an implementable manner, the spring member 3 and the deformed clamping member 4 are respectively provided with a receiving insertion cavity extending along the depth direction of the receiving hole 21; when the pin plug 11 is correspondingly inserted into the receiving insertion cavity, the spring member 3 and the deformed clamping member 4 are respectively deformed along the radial direction of the pin plug 11 and exert a clamping fixing force along the radial direction.
[0052] Specifically, in combination with Figure 2 , Figure 3 and Figure 4 , it is further explained in detail that the spring member 3 and the deformed clamping member 4 are respectively provided with a receiving insertion cavity extending along the depth direction of the receiving hole 21, so that the pin plug 11 can correspondingly expand and deform the spring member 3 and the deformed clamping member 4 from inside to outside by being inserted into the receiving insertion cavity, so as to realize uniform deformation of the spring member 3 and the deformed clamping member 4 along each radial direction of the pin plug 11 and simultaneously exert a clamping fixing force along each radial direction of the pin plug 11, and fully ensure the uniformity and stability of the clamping stress of the pin plug 11.
[0053] The above-mentioned arrangement of the spring member 3 and the deformed clamping member 4 has the beneficial effects of simple structure and ensuring the uniformity and stability of the clamping stress of the pin plug 11.
[0054] In an implementable manner, the deformed clamping member 4 is arranged as a clamping cylinder 42 with a notch 41 formed in the peripheral wall; the pin plug 11 can be tightly inserted into the receiving insertion cavity inside the clamping cylinder 42, and the peripheral wall of the clamping cylinder 42 is deformed and expanded to abut against the inner hole wall of the receiving hole 21.
[0055] Specifically, in combination with Figure 2 andFigure 4 In further detail, the deformation clamping member 4 is specifically provided as a clamping cylinder 42 with a notch slot 41 in the peripheral wall, and the clamping cylinder 42 has an insertion receiving cavity inside which can tightly receive the pin plug 11. When the pin plug 11 is tightly inserted into the insertion receiving cavity of the clamping cylinder 42, the peripheral wall of the clamping cylinder 42 correspondingly deforms and expands. Since the peripheral wall of the clamping cylinder 42 is also provided with the notch slot 41, the clamping cylinder 42 can deform not only by the material characteristics of the clamping cylinder 42 itself, but also by the notch slot 41. Thus, the upper limit of the deformation range of the clamping cylinder 42 is improved, and the clamping cylinder 42 can provide a greater clamping and fixing force to the pin plug 11 during the insertion process.
[0056] The specific structure of the deformation clamping member 4 has the beneficial effects of simple structure, greater deformation, and greater clamping and fixing force.
[0057] In an embodiment, the notch slot 41 is provided in a linear or helical shape along the axial direction of the clamping cylinder 42.
[0058] Specifically, in combination with Figure 4 In further detail, the notch slot 41 is provided in a linear shape along the axial direction of the clamping cylinder 42. When the insertion receiving cavity inside the clamping cylinder 42 is inserted by the pin plug 11, the clamping cylinder 42 expands relative to the slot width direction of the notch slot 41, so that the clamping cylinder 42 with a C-shaped cross section can tightly clamp and fix the pin plug 11 with a large arc.
[0059] In addition, the notch slot 41 is provided in a helical shape along the axial direction of the clamping cylinder 42. The clamping cylinder 42 is substantially similar to a threaded spring. When the insertion receiving cavity inside the clamping cylinder 42 is inserted by the pin plug 11, the clamping cylinder 42 also expands relative to the slot width direction of the notch slot 41, so that the clamping cylinder 42 with a threaded shape can tightly clamp and fix the pin plug 11 with multiple turns.
[0060] The two setting modes of the notch slot 41 in the clamping cylinder 42 can make the clamping cylinder 42 deform greatly and effectively clamp and fix the pin plug 11.
[0061] In an embodiment, the outer wall of the clamping cylinder 42 is also provided with a protruding structure 43. When the peripheral wall of the clamping cylinder 42 deforms and expands, the protruding structure 43 is fixedly abutted against the inner hole wall of the insertion hole 21.
[0062] Specifically, in combination with Figure 2 and Figure 4Further in detail, the outer wall of the clamping cylinder 42 is further provided with a protruding structure 43, and the protruding structure 43 can be provided with multiple, which can be uniformly distributed or randomly distributed in the outer wall of the clamping cylinder 42. When the peripheral wall of the clamping cylinder 42 deforms and expands, the protruding structure 43 can be bidirectionally clamped by the clamping cylinder 42 and the receiving hole 21 of the female connector 2. On the one hand, it can further increase the clamping stability of the pin plug 11, and on the other hand, it can also improve the installation stability of the clamping cylinder 42 in the receiving hole 21.
[0063] In an implementation manner, the protruding structure 43 is provided as a hemispherical protruding head, and the hemispherical protruding head is provided with multiple on the outer wall of the clamping cylinder 42.
[0064] Specifically, in combination with Figure 4 Further in detail, the protruding structure 43 is specifically provided as a hemispherical protruding head. When the clamping cylinder 42 is inserted and expanded by the pin plug 11, the clamping cylinder 42 will drive the protruding structure 43 to slide along the hole wall of the receiving hole 21 to a certain extent. By specifically providing the protruding structure 43 as a hemispherical protruding head, the frictional resistance of the protruding structure 43 during sliding can be reduced, thereby improving the smoothness of the clamping cylinder 42 during deformation and expansion.
[0065] In addition, the hemispherical protruding head can also reduce the risk of scratching and damaging the hole wall of the receiving hole 21.
[0066] In an implementation manner, one end of the deforming clamping piece 4 is in abutment with the clamping spring piece 3, and the other end is in abutment with the bottom end of the receiving hole 21. When the pin plug 11 is correspondingly inserted into the receiving hole 21, the clamping spring piece 3 and the deforming clamping piece 4 can exert a pushing force on each other in the hole depth direction of the receiving hole 21.
[0067] Specifically, in combination with Figure 1 and Figure 2 Further in detail, one end of the deforming clamping piece 4 is in abutment with the clamping spring piece 3, and the other end is in abutment with the bottom end of the receiving hole 21. When the pin plug 11 is correspondingly inserted into the receiving hole 21, the clamping spring piece 3 and the deforming clamping piece 4 can deform in the hole depth direction in addition to the radial direction of the receiving hole 21. However, the ends of the clamping spring piece 3 and the deforming clamping piece 4 are connected to each other. Thus, the two can exert a pushing force on each other in the hole depth direction, so that the deformation in the hole depth direction can be offset to a certain extent, and the elastic deformation can occur in the radial direction of the receiving hole 21 to the greatest extent, thereby enabling the clamping spring piece 3 and the deforming clamping piece 4 to be better clamped and fixed in the radial direction.
[0068] In an implementation manner, the receiving hole 21 has a first hole section and a second hole section for mounting the clamping spring piece 3 and the deforming clamping piece 4, respectively. The diameters of the first hole section and the second hole section are the same, or the diameter of the first hole section is smaller than that of the second hole section.
[0069] Specifically, in combination with Figure 1 and Figure 2 Further detailed, at this time is to set the diameter of the first hole section and the second hole section in the receptacle 21 to be equal, so that when the clamping spring 3 and the deformed clamping piece 4 are installed in the receptacle 21, the clamping spring 3 and the deformed clamping piece 4 can be fixed and installed by being sequentially inserted in order.
[0070] In addition, when the diameter of the first hole section in the receptacle 21 is set to be smaller than the diameter of the second hole section, a stepped retaining table can be formed at the communication between the first hole section and the second hole section, so that the deformed clamping piece 4 can be installed in a limited and clamped manner, further improving the installation stability of the clamping spring 3 and the deformed clamping piece 4 in the receptacle 21.
[0071] In an implementable manner, the clamping spring 3 includes an installation cylinder 31 and a deformed spring 32; the installation cylinder 31 is respectively arranged at both ends of the deformed spring 32; the deformed spring 32 has an inwardly protruding arch-shaped portion, and the arch-shaped portion can be pressed flat by the pin plug 11.
[0072] Specifically, in combination with Figure 3 Further detailed, at this time the clamping spring 3 is specifically arranged to include an installation cylinder 31 and a deformed spring 32, and the installation cylinder 31 is respectively arranged at both ends of the deformed spring 32, and the deformed spring 32 has an inwardly protruding arch-shaped portion, so that when the arch-shaped portion can be inserted and pressed by the pin plug 11, it can be elastically flattened to a certain extent, so that the installation cylinder 31 at both ends is away from each other, and the arch-shaped portion in the deformed spring 32 can be clamped to the pin plug 11 under the action of the elastic deformation recovery force of itself, thereby realizing the clamping and limiting function of the pin plug 11.
[0073] The specific arrangement of the clamping spring 3 has the beneficial effects of simple structure and effective elastic deformation clamping of the pin plug 11.
[0074] In an implementable manner, the deformed spring 32 is arranged in multiple; the multiple deformed springs 32 are arranged in a ring array around the center of the clamping spring 3.
[0075] Specifically, in combination with Figure 3 Further detailed, at this time the deformed spring 32 is specifically arranged to four, and the four deformed springs 32 are arranged in a ring array around the center of the clamping spring 3, so that when the pin plug 11 is inserted into the center of the four deformed springs 32, the arch-shaped portions in the four deformed springs 32 can be synchronously pressed, so that the four deformed springs 32 are synchronously deformed and clamped towards the center of the pin plug 11 at the same time.
[0076] The specific arrangement of the deformation spring 32 has the advantages of simple structure and synchronous deformation, and the corresponding direction can clamp the pin plug 11.

In the description of the present disclosure, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.
[0078] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present disclosure, which should be covered by the protection scope of the present disclosure.
