DETAILED DESCRIPTION

[0032] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0033] like Figures 1 to 9As shown, the utility model provides a plug-in connector for a single-pair Ethernet, comprising a male end component 1 and a female end component 6, wherein the male end component 1 comprises an inner housing 2 and a first outer housing 3 arranged outside the inner housing 2, wherein a plug-in frame 21 is arranged at one end of the inner housing 2 and extends to the outside of the first outer housing 3, wherein an arc-shaped guide portion 22 is extended at the port of the plug-in frame 21, and a locking spring 23 is arranged on the top wall of the inner housing 2, wherein the movable end of the locking spring 23 extends into the arc-shaped guide portion 22. ; A snap-on block 24 is provided on the locking spring 23, and the first outer shell 3 is provided with a pressing component 7 for pressing the locking spring 23; the female end component 6 includes a second outer shell 61, and a guide mechanism is provided at the port of the second outer shell 61. An insertion space 63 for accommodating the insertion frame 21 and the locking spring 23 is formed in the second outer shell 61, and a card interface 64 for accommodating the snap-on block 24 is provided on the top wall of the second outer shell 61, and the insertion space 63 is communicated with the card interface 64.

[0034] In the present embodiment, a guiding mechanism is provided at the port of the second outer shell 61 of the female end component 6. When the male end component 1 and the female end component 6 are plugged in, the male end component 1 is moved to the guiding mechanism. When the male end component 1 moves forward, it can accurately enter the plug-in space 63 of the female end component 6 under the guidance of the guiding mechanism. Therefore, the single-pair Ethernet plug-in connector in the present embodiment does not need to accurately align the port of the male end component 1 and the port of the female end component 6 when plugging in, which saves time and realizes quick plug-in. In addition, since an arc-shaped guide portion 22 is extended at the port of the plug-in frame 21 of the male end component 1, and the movable end of the locking spring piece 23 extends into the arc-shaped guide portion 22, that is, the arc-shaped guide portion 22 has a limiting effect on the movable end of the locking spring piece 23, the locking spring piece 23 can be guided into the plug-in space 63 through the arc-shaped guide portion 22, and direct plug-in can be performed without pressing the locking spring piece 23. Compared with the prior art where the locking spring piece 23 needs to be pressed first to retract it and then plugged in, it saves time and effort and is quick and convenient. A clamping block 24 is provided on the locking spring piece 23. Specifically, the clamping block 24 protrudes from the upper surface of the locking spring piece 23, and an inclined surface is provided on one side of the clamping block 24 close to the arc-shaped guide portion 22, which helps to guide the clamping block 24 into the plug-in space 63. The clamping block 24 forces the locking spring piece 23 to be compressed due to the pressure at the top of the plug-in space 63. When the clamping block 24 runs to the card interface 64, since there is no pressure to force the locking spring piece 23 to be compressed at this time, the locking spring piece 23 recovers and drives the clamping block 24 to be clamped into the card interface 64. The position of the clamping block 24 is limited by the card interface 64, thereby preventing the male end component 1 and the female end component 6 from being easily displaced during use.

[0035] Furthermore, there are two clamping blocks 24, and the two clamping blocks 24 are respectively in contact with the two side walls of the card interface 64. In this embodiment, the two clamping blocks 24 cooperate with the two side walls of the card interface 64, which helps to further ensure the relative position between the clamping blocks 24 and the card interface 64, thereby ensuring the relative position between the male end component 1 and the female end component 6, and ensuring the plugging stability.

[0036] Furthermore, the guide mechanism includes guide bevels 65 located at the upper and lower sides of the port of the second outer shell 61, and arc-shaped guide pieces 66 located at the left and right sides of the port of the second outer shell 61. In this embodiment, by arranging the guide bevels 65 and the arc-shaped guide pieces 66 around the port of the second outer shell 61, when plugging, the port of the male end component 1 only needs to contact the guide bevels 65 and the arc-shaped guide pieces 66, without the need to accurately align the port of the male end component 1 and the port of the female end component 6 first, and under the guidance of the guide bevels 65 and the arc-shaped guide pieces 66, it can accurately enter the plug-in space 63 of the female end component 6, saving plug-in time.

[0037] Furthermore, the inner shell 2 is also provided with a plurality of positioning protrusions 25, and the second outer shell 61 is provided with a plurality of positioning holes 611 corresponding to the positioning protrusions 25, and each of the positioning holes 611 is provided with a positioning spring 612 for fixing the positioning protrusion 25. Specifically, a positioning protrusion 25 is respectively provided on the outside of the bottom wall and the two side walls of the inner shell 2, and a positioning hole 611 and a positioning spring 612 are respectively provided on the bottom wall and the two side walls of the second outer shell, and a limiting gap is formed between the hole wall of the positioning hole 611 and the end of the positioning spring 612, and the positioning protrusion 25 enters the limiting gap to position the positioning protrusion 25; when plugging in, the clamping block 24 on the locking spring 23 on the top wall of the inner shell 2 is clamped by the clamping block 24 on the top wall of the second outer shell 61. The male end component 1 is positioned by the opening 64, and the positioning protrusions 25 on the bottom wall and the two side walls of the inner shell 2 are positioned by the positioning holes 611 and the positioning springs 612 in the bottom wall and the two side walls of the second outer shell 61. Therefore, the four side walls of the inner shell 2 in the male end component 1 are fixed to the four side walls of the second outer shell 61 in the female end component 6, so that the connection between the male end component 1 and the female end component 6 is more secure, avoiding displacement of the male end component and the female end component during use, and further ensuring the stability of plugging.

[0038] Furthermore, the pressing component 7 includes a pressing portion 71 connected to the first outer shell 3, and the other end of the pressing portion 71 is provided with a force block 72 in the vertical direction; the locking spring piece 23 includes an arc-shaped protrusion, and the arc-shaped protrusion is located directly below the force block 72. Specifically, the pressing portion 71 and the force block 72 are roughly "L"-shaped; when the male end component 1 needs to be separated from the female end component 6, the pressing portion 71 is pressed first, and the pressing portion 71 drives the force block 72 to move downward, thereby applying pressure vertically downward to the arc-shaped protrusion of the locking spring piece 23, and the locking spring piece 23 moves downward, thereby driving the card block 24 to disengage from the card interface 64, and then the male end component 1 is pulled away from the female end component 6, so that the plug-in frame 21 and the locking spring piece 23 are disengaged from the plug-in space 63, and the male end component 1 and the female end component 6 can be separated.

[0039] Furthermore, the surface of the pressing portion 71 is provided with an anti-skid protrusion 73, and the first outer shell 3 is provided with a gripping portion 31 on a side opposite to the pressing portion 71, and the surface of the gripping portion 31 is also provided with an anti-skid protrusion 73. In this embodiment, when the male end component 1 needs to be separated from the female end component 6, the thumb presses the pressing portion 71 and the index finger presses against the gripping portion 31. By providing the anti-skid protrusion 73 on the surfaces of the pressing portion 71 and the gripping portion 31, the fingers are prevented from slipping on the pressing portion 71 and the gripping portion 31, so that it is convenient to apply force to pull the male end component 1 outward.

[0040] Furthermore, the male end assembly 1 also includes a first rubber core 4 and a pin terminal 5 arranged in the first rubber core 4, the first rubber core 4 is arranged in the inner shell 2, one end of the pin terminal 5 extends out of the first rubber core 4 and extends into the plug-in frame 21, and the other end of the pin terminal 5 is connected to a wire 8.

[0041] Furthermore, the female end component 6 also includes a second rubber core 67 and a socket terminal 68 disposed in the second rubber core 67. The second rubber core 67 is disposed in the second outer shell 61. The plug-in space 63 is formed between the second outer shell 61 and the second rubber core 67. During plug-in, the second rubber core 67 is inserted into the plug-in frame 21 and the pin terminal 5 is inserted into the socket terminal 68. In this embodiment, when the male end component 1 and the female end component 6 are plugged in, the second rubber core 67 cooperates with the plug-in frame 21, thereby having a certain auxiliary positioning effect on the plug-in between the pin terminal 5 and the socket terminal 68.

[0042] Further, the inner shell 2 comprises an upper cover 26 and a lower cover 27 that are mutually engaged, the locking spring 23 is arranged in the upper cover 26, and the plug-in frame 21 is arranged in the lower cover 27. In this embodiment, the inner shell 2 is arranged as an upper cover 26 and a lower cover 27 that are mutually engaged, which is convenient for manufacturing and for installing the first rubber core 4 into the inner shell 2. Specifically, the cross-sections of the upper cover 26 and the lower cover 27 are both "ㄇ" shaped, wherein a clamping block 271 is arranged on both side walls of the lower cover 27, and a clamping hole 261 that matches the clamping block 271 is arranged on both side walls of the upper cover 26. When installing, the first rubber core 4 is first placed in the lower cover 27, and then the clamping block 271 is clamped into the clamping hole 261, so that the installation between the upper cover 26 and the lower cover 27 can be realized and the installation of the first rubber core 4 can be realized, which is convenient and quick.

[0043] Furthermore, an arc-shaped wire positioning block 28 is provided at one end of the upper cover 26 away from the locking spring 23 and an end of the lower cover 27 away from the plug-in frame 21. The wire 8 passes through the arc-shaped wire positioning block 28 and extends to the outside of the first outer shell 3. The first outer shell 3 is provided with a locking nut 9 at a position corresponding to the arc-shaped wire positioning block 28. In this embodiment, the wire 8 is clamped and positioned by providing the arc-shaped wire positioning block 28, and is locked and positioned by the locking nut 9. When the wire 8 outside the first outer shell 3 is subjected to force, the connection between the wire 8 and the pin terminal 5 will not be affected.

[0044] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
