Description

Technical Field

[0001] This invention relates to an electrical connector, and more particularly to an electrical connector involving a locking mechanism. Background Technology

[0002] Existing electrical connectors, including the insulating body and the locking mechanism mounted on the insulating body, typically require manual pressing of the locking mechanism to unlock. As electronic devices become increasingly miniaturized, there is not much internal space to accommodate finger pressing of the locking mechanism, making unlocking inconvenient. When the locking mechanism is mounted on the insulating body, a pull mechanism is used to pull the locking mechanism to unlock. However, because electrical connectors are pulled to unlock frequently, the locking mechanism is highly likely to be damaged due to connector insertion / removal or external impact. In this case, the entire insulating body needs to be replaced and all terminals reinstalled. The insulating body usually integrates precision terminals and other structures, and its molds are complex and the material requirements are high, resulting in a relatively high cost compared to the entire electrical connector, making replacement costly.

[0003] Therefore, it is necessary to design a new electrical connector to overcome the above problems. Summary of the Invention

[0004] To address the problems faced by the prior art, the present invention aims to provide an electrical connector in which a locking element is detachably connected to an insulating body and a housing. A pulling element pulls the pulled portion of the locking element, and with the connection point between the support portion and the connecting portion as a fulcrum, the locking portion and the pulled portion deflect in opposite directions, thus releasing the locking portion from the mating connector. When the locking element is damaged, only the locking element needs to be replaced, resulting in low cost.

[0005] To achieve the above objectives, the present invention employs the following technical means: An electrical connector for mating with a mating connector, characterized in that it comprises: an insulating body including a front end face and a rear end face; a plurality of terminals respectively disposed on the insulating body; a housing detachably connected to the insulating body; the housing including a receiving space located behind the rear end face; a locking member detachably connected to the insulating body and the housing, the locking member including a locking portion, a connecting portion and a pulled portion disposed in a front-rear direction, the locking portion being used to engage with the mating connector, the locking member further including a support portion connected to the connecting portion; a pulling member, the first end of which is connected to the pulled portion, a portion of which is located within the receiving space, the second end of which extends out of the housing, when the pulling member pulls the pulled portion, with the connection point of the support portion and the connecting portion as a fulcrum, the locking portion and the pulled portion deflect in opposite directions, and the locking portion releases the mating connector.

[0006] Furthermore, the insulating body includes an upper end face, two locking portions located on the upper end face, and a first connecting rib.

Along the left-to-right direction, the second connecting ribs maintain a distance from the pulled part.

[0010] Furthermore, the locking component includes two rear positioning parts on the left and right sides and a third connecting rib connecting the two rear positioning parts. When viewed from the front and rear direction, the projection of the pulled part in the vertical direction is located between the projection of the support part and the projection of the third connecting rib. In the front and rear direction, the third connecting rib maintains a distance from the pulled part.

[0011] Furthermore, the housing includes a front surface and two locking parts. Both locking parts and the through hole are recessed from the front surface to the rear. The two locking parts are located on the left and right sides of the through hole. The rear positioning part enters the locking part, so that the locking part restricts the vertical displacement of the rear positioning part. The locking member includes two rear positioning parts on the left and right sides and a third connecting rib connecting the two rear positioning parts. The front surface is located behind the third connecting rib, preventing the third connecting rib from moving backward.

[0012] Furthermore, the pulled part includes two plate parts and a fastening part connecting the two plate parts. In the vertical direction, the upper surface of the fastening part is higher than the lower surface of the third connecting rib, and the pulling member abuts against the upper surface of the fastening part and the lower surface of the third connecting rib respectively.

[0013] Furthermore, the locking component includes two front positioning portions located on the left and right sides of the support portion, respectively. Each front positioning portion includes a first positioning section and a second positioning section. The left and right sides of the first positioning section are integrally connected to the support portion and the second positioning section, respectively. The thickness of the second positioning section is greater than that of the first positioning section in the vertical direction. The insulating body includes an upper end face and two locking portions located on the upper end face. The two locking portions are located on the left and right sides of the support portion, respectively, and are located between the two second positioning sections. Each locking portion includes a front stop section connected to the upper end face and an upper stop section located behind the front stop section. The front stop section is located in front of the first positioning section and prevents the first positioning section from moving forward. The upper stop section maintains a distance from the upper end face and is located between the support portion and the second positioning section in the horizontal direction, preventing the support portion and / or the second positioning section from moving left and right.

[0014] Furthermore, the locking element is located between the insulating body and the housing. The support part connects upward to the connecting part and abuts downward against the insulating body. The connecting part includes a top surface and a bottom surface that are opposite each other in the vertical direction, as well as two notches formed by recesses from the bottom surface to the top surface. In the left-right direction, the two notches are located on both sides of the connection between the support part and the connecting part in the front-back direction.

[0015] Furthermore, the insulating body includes an upper end face and two locking portions located on the upper end face. The two locking portions are arranged in the left-right direction. The locking member includes two front positioning portions. A part of the locking portion is located in front of the front positioning portion, preventing the front positioning portion from moving forward. The support portion abuts against the upper end face downward, and the support portion is integrally connected to the connecting portion upward. The two locking portions are located on the left and right sides of the connecting portion and the support portion, respectively, preventing the support portion and / or the front positioning portion from moving in the left-right direction.

[0016] Furthermore, the pulled part includes two plate parts and a fastening part connecting the two plate parts. The two plate parts extend upward and backward from the connecting part, respectively. The fastening part and the connecting part form a through hole at intervals. In the vertical direction, the upper surface of the fastening part is higher than the upper surface of the connecting part. After the pulling member passes through the through hole, it abuts against the upper surface of the fastening part.

[0017] Furthermore, the pulled part also includes an abutment part connecting the two plates. In the vertical direction, the upper surface of the fastening part is higher than the upper surface of the abutment part. In the front-back direction, the abutment part and the fastening part are spaced apart to form a through groove. The through hole and the through groove are interconnected. The pulling member passes through the through groove, and a part of the pulling member abuts against the upper surface of the abutment part.

[0018] Furthermore, the connecting part and the abutting part are spaced apart along the front-to-back direction to form a clearance space, which connects the perforation and the groove.

[0019] An electrical connector for mating with a mating connector, characterized in that it comprises: an insulating body including a front end face, a rear end face, an upper end face, and two locking portions located on the upper end face, the locking portions including a front stop segment and an upper stop segment extending rearward from the front stop segment; a plurality of terminals respectively disposed on the insulating body; a housing detachably connected to the insulating body; the housing including a receiving space located behind the rear end face; and a locking member detachably connected to the insulating body and the housing, the locking member including a locking portion and a connecting portion disposed in a front-rear direction, the locking portion being used to engage with the mating connector, the locking member including a locking portion located behind the connecting portion. The support part and the front positioning part connected to the connecting part are located directly below the support part. The front positioning part includes a positioning groove recessed from top to bottom. Two positioning grooves are located on the left and right sides of the support part. Along the left and right direction, the positioning groove includes a first inner wall and a second inner wall opposite to the first inner wall. The front stop section is located in front of the front positioning part to stop the front positioning part from moving forward. The upper stop section is positioned in the positioning groove to stop the positioning groove from moving left and right. When force is applied to the locking part, the locking part deflects with the connection between the support part and the connecting part as the fulcrum, causing the locking part to release from the mating connector. The first inner wall of the positioning groove is located on the fulcrum.

[0020] Furthermore, the locking component includes two front positioning parts, two rear positioning parts, two second connecting ribs, and a third connecting rib connecting the two rear positioning parts, arranged side by side. Along the front-rear direction, each second connecting rib integrally connects one front positioning part and one rear positioning part. The housing includes a front surface and two locking parts. The two locking parts are recessed from the front surface to the rear. The front surface is located behind the third connecting rib, preventing the third connecting rib from moving backward. The rear positioning parts enter the locking parts, so that the locking parts restrict the vertical displacement of the rear positioning parts.

[0021] Furthermore, the locking component includes a latching portion located behind the connecting portion, the upper surface of the latching portion being higher than the lower surface of the third connecting rib, the latching portion and the connecting portion forming a through hole spaced apart from each other, and the upper surface of the latching portion being higher than the upper surface of the connecting portion in the vertical direction; a pulling member, the pulling member passing through the through hole and abutting against the upper surface of the latching portion and the lower surface of the third connecting rib, a part of the pulling member being located within the receiving space, and the second end of the pulling member extending out of the housing, when the pulling member pulls the latching portion, the locking portion and the latching portion deflect in opposite directions, and the locking portion releases the mating connector.

[0022] Compared with the prior art, the present invention has the following beneficial effects: By detachably connecting the locking element to the insulating body and the housing, when the locking element is damaged due to frequent pulling, only the locking element needs to be replaced. The locking elements are simple auxiliary structures with simple molds and less material, and will not affect the insulating body and terminals. The insulating body usually integrates precision terminals and other structures, and its molds are complex and the material requirements are high, so the cost is relatively high compared to the entire electrical connector.

[0023] The housing is detachably connected to the insulating body. When the housing is damaged, it can be easily replaced. The housing includes a receiving space located behind the rear end face, which can facilitate cable management and protect the cables. It can also limit the direction of cable exit to meet different wiring application scenarios. Attached Figure Description

[0025] The direction in which the mating connector 200 connects to the insulating body 10 is defined as the front-back direction, the up-down direction as the Z-axis, the upward direction as the positive Z-axis direction, the front-back direction as the X-axis, and the forward direction as the positive X-axis direction.

[0026] like Figures 1 to 2 As shown, the electrical connector 100 includes an insulating body 10, a plurality of terminals T disposed on the insulating body 10, a housing 20 detachably connected to the insulating body 10, a locking member 30 detachably connected to the insulating body 10 and the housing 20, and a pull member 40 connected to the locking member 30. One end of a cable (not shown) is electrically connected forward to the terminals T, and the other end extends backward out of the housing 20 and mates forward with a mating connector 200. Along the front-to-back direction, the locking member 30 is located between the insulating body 10 and the housing 20; that is, the locking member 30, the insulating body 10, and the housing 20 are separate components. The locking portion 301 is used to engage with the mating connector 200.

[0027] like Figures 2 to 3 As shown, the insulating body 10 includes a base 101, from which a plurality of cylindrical portions 102 extend forward. The base 101 has a rear end face 1011, an upper end face 1012, two locking portions 103 located on the upper end face 1012, and a first connecting rib K. The two locking portions 103 are arranged in the left-right direction, and the first connecting rib K is integrally connected to the two locking portions 103 in the left-right direction, which helps to strengthen the strength of the two locking portions 103 and reduces the deformation of the locking portions 103 in the left-right direction. The plurality of cylindrical portions 102 have a front end face 1021.

[0028] like Figure 2 As shown, the locking portion 103 includes a front stop segment 1031 connected to the upper end face 1012 and an upper stop segment 1032 located behind the front stop segment 1031. The front stop segment 1031 extends upward from the upper end face 1012, and the upper stop segment 1032 extends rearward from the front stop segment 1031, maintaining a distance between the upper stop segment 1032 and the upper end face 1012. In this embodiment, the upper stop segment 1032 and the front stop segment 1031 are perpendicular to each other. In other embodiments, the upper stop segment 1032 and the front stop segment 1031 are not perpendicular, and the upper stop segment 1032 extends rearward and upward from the front stop segment 1031.

[0029] like Figure 16As shown, the housing 20 includes an upper wall 201 and a receiving space 202 located on the rear end face 1011. The upper wall 201 includes a front surface 2011, two retaining portions 2012 recessed from the front surface 2011 to the rear, and a through hole 2013. The two retaining portions 2012 are located on the left and right sides of the through hole 2013. In other embodiments, the housing 20 also includes a front wall (not shown) and a rear wall (not shown). The retaining portions 2012 and the through hole 2013 can be disposed on the front wall (not shown), or the retaining portions 2012 can be disposed on the front wall (not shown) and the through hole 2013 can be disposed on the rear wall (not shown), or the retaining portions 2012 can be disposed on the rear wall (not shown) and the through hole 2013 can be disposed on the front wall (not shown). The retaining portions 2012 can be one or multiple.

[0030] like Figures 13 to 15 As shown, the locking member 30 includes a locking part 301, a connecting part 302, a pulled part 303, two support parts 304 fixed to the connecting part 302, two front positioning parts 305 located on the left and right sides of the support parts 304, two rear positioning parts 306 arranged side by side, two second connecting ribs 307, and a third connecting rib 308 connecting the two rear positioning parts 306.

[0031] like Figure 2 and Figure 13As shown, the locking part 301, connecting part 302, and pulled part 303 are arranged sequentially in the front-to-back direction. The locking part 301 is used to engage with the docking connector 200. When the pulling member 40 pulls the pulled part 303, the locking part 301 and the pulled part 303 deflect in opposite directions with the connection between the supporting part 304 and the connecting part 302 as the fulcrum. At the same time, the locking part 301 is released from the docking connector 200. The supporting part 304 is integrally connected to the connecting part 302 upwards and abuts against the upper end face 1012 downwards. In other embodiments, the supporting part 304 may be located on the left and right sides of the connecting part 302, or the supporting part 304 may be a separate part that is connected to the connecting part 302 and abuts against the upper end face 1012 downwards. The connecting part 302 has a recess (not shown), and the supporting part 304 has a protrusion (not shown). The protrusion enters the recess to achieve a fixed connection. Each of the connecting portion 302 and the supporting portion 304 has a locking portion 103 on its left and right sides. In this embodiment, the locking portions 103 have gaps with the connecting portion 302 and the supporting portion 304 respectively, preventing the supporting portion 304 and the front positioning portion 305 from moving in the left and right directions. In other embodiments, the locking portions 103 are used to stop the connecting portion 302 and the supporting portion 304 from moving in the left and right directions. The two front positioning portions 305 are connected to the supporting portions 304 on the left and right sides. The front positioning portions 305 abut downward against the upper end surface 1012. In the front-back direction, each second connecting rib 307 connects the front positioning portion 305 and the two rear positioning portions 306 in the front-back direction. The front stop segment 1031 is located in front of the front positioning portion 305, preventing the front positioning portion 305 from moving forward.

[0032] like Figure 4 , Figure 6 and Figure 13 As shown, the connecting part 302 includes a top surface 3021 and a bottom surface 3022 that are opposite each other in the vertical direction, and two notches 3023 formed by recesses from the bottom surface 3022 to the top surface 3021. Maintaining a distance between the bottom surface 3022 and the first connecting rib K along the vertical direction avoids interference between them. This also facilitates the smooth lifting of the locking member 30 to unlock the connector 200. Along the left-right direction, two notches 3023 are located on either side of the connection between the support part 304 and the connecting part 302 along the front-back direction. This arrangement allows the locking member 30 to use the connection between the support part 304 and the connecting part 302 as a fulcrum when the pulling member 40 pulls the pulled part 303. When the locking part 301 and the pulled part 303 deflect in opposite directions, the connecting part 302 at the notch 3023 has a large deformation space, ensuring that the pulled part 303 can be pressed smoothly and the locking part 301 can be lifted smoothly. When the user pulls the pulling member 40, unlocking is achieved with less force, improving unlocking efficiency.

[0033] like Figure 6 , Figure 7 and Figure 13As shown, the pulled portion 303 includes two plate portions 3031, a fastening portion 3032 connecting the two plate portions 3031, and an abutting portion 3033 connecting the two plate portions 3031. The two plate portions 3031 extend upward and backward from the connecting portion 302, respectively. In the vertical direction, the upper surface of the fastening portion 3032 is simultaneously higher than the upper surface of the abutting portion 3033, the upper surface of the connecting portion 302, and the lower surface of the third connecting rib 308. The fastening portion 3032 and the connecting portion 302 form a through hole 3034 spaced apart from each other. In the front-back direction, the abutting portion 3033 and the fastening portion 3032 form a through groove 3035 spaced apart from each other. The through hole 3034 and the through groove 3035 are interconnected. When the pulling member 40 passes through the through hole 3034 and is fixed to the fastening portion 3032, the pulling member 40 can pass through the through groove 3035 and exit the pulled portion 303. Along the front-to-back direction, the connecting portion 302 and the abutting portion 3033 are spaced apart to form a clearance space 3036. The clearance space 3036 also connects the through hole 3034 and the through groove 3035. This arrangement facilitates the pulling member 40 to pass through the through hole 3034 and the through groove 3035, while also reducing the thickness of the pulled portion 303 and preventing deformation of the pulled portion 303 after molding. In other embodiments, the plate portion 3031 can extend directly rearward from the connecting portion 302, and the fastening portion 3032 connects two adjacent plate portions 3031 along the left-to-right direction. After the pulling member 40 connects to the fastening portion 3032, it passes through the housing 20.

[0034] like Figure 2 , Figure 6 and Figure 7 As shown, the pulling member 40 includes a first end 401 and a second end 402. The first end 401 is connected to the pulled portion 303. A portion of the pulling member 40 is located within the receiving space 202. The second end 402 of the pulling member 40 passes through the through hole 2013 and extends out of the housing 20. In this embodiment, after the pulling member 40 passes through the through hole 3034, it abuts against the upper surface of the fastening portion 3032 and the lower surface of the third connecting rib 308. After the pulling member 40 passes through the through groove 3035, a portion of the pulling member 40 abuts against the upper surface of the abutting portion 3033. Compared to not having the abutting portion 3033, the abutting portion 3033 of the pulling member 40 helps to position the pulling member 40 when it exits the pulled portion 303, preventing excessive vertical displacement of the pulling member 40 during pulling. Of course, in other embodiments, after the pull member 40 passes through the through slot 3035, it may not abut against the abutment portion 3033, but directly abut against the lower surface of the third connecting rib 308.

[0035] like Figure 4 , Figure 10 and Figure 13As shown, each front positioning part 305 includes a first positioning segment 3051, a second positioning segment 3052 connecting the first segment, and a positioning groove 3053 recessed from top to bottom. The support part 304 and the second positioning segment 3052 are integrally connected to the left and right sides of the first positioning segment 3051, respectively. The thickness of the second positioning segment 3052 in the vertical direction is greater than the thickness of the first positioning segment 3051. The first positioning segment 3051 is thinner. The first positioning segment 3051 abuts against the upper end face 1012, and the second positioning segment 3052 abuts against the upper end face 1012. When the pulling member 40 pulls the pulled part 303, with the connection between the support part 304 and the connecting part 302 as the fulcrum, when the locking part 301 and the pulled part 303 deflect in opposite directions, the pulling force on the connection between the support part 304 and the connecting part 302 can be reduced, which is beneficial to the deflection of the connecting part 302. The second positioning segment 3052 is thicker, which is beneficial to improving the local strength of the locking member 30.

[0036] like Figure 2 , Figure 10 and Figure 11 As shown, the upper stop segment 1032 is located above the first positioning segment 3051, and the upper stop segment 1032 blocks the first positioning segment 3051 from moving upward. The front stop segment 1031 is located in front of the first positioning segment 3051, and the front stop segment 1031 blocks the first positioning segment 3051 from moving forward. The upper end face 1012 abuts against the first positioning segment 3051 upward. The positioning of the first positioning segment 3051 by the upper stop segment 1032, the front stop segment 1031 and the upper end face 1012 indirectly realizes the limitation of the support part 304, and ensures the stability of the locking fastener 30 when unlocking.

[0037] like Figure 2 , Figure 10 and Figure 11As shown, the positioning groove 3053 is located between the support portion 304 and the second positioning section 3052. In the left-right direction, the positioning groove 3053 includes a first inner wall 30531 and a second inner wall 30532 opposite to the first inner wall 30531. A portion of the first inner wall 30531 is located on the support portion 304, and the second inner wall 30532 is located on the second positioning section 3052. In the left-right direction, the upper stop section 1032 is positioned in the positioning groove 3053, that is, the upper stop section 1032 is located between the support portion 304 and the second positioning section 3052, causing the upper stop section 1032 to prevent the positioning groove 3053 from moving left and right. In this embodiment, both the left and right upper stop segments 1032 maintain a distance from the first inner wall 30531, that is, both the left and right upper stop segments 1032 maintain a distance from the support portion 304. The left upper stop segment 1032 prevents the left second inner wall 30532 from moving to the right, that is, the left upper stop segment 1032 prevents the left second positioning segment 3052 from moving to the right. The right upper stop segment 1032 prevents the right second inner wall 30532 from moving to the left, that is, the right upper stop segment 1032 prevents the right second positioning segment 3052 from moving to the left. When force is applied to the locking member 30, with the connection between the support portion 304 and the connecting portion 302 as the fulcrum, the locking portion 301 deflects, causing the locking portion 301 to release from the mating connector 200, and the first inner wall 30531 of the positioning groove 3053 is located on the fulcrum.

[0038] In other embodiments, one of the upper stop segments 1032 blocks the first inner wall 30531 and the second inner wall 30532 on the same side, that is, one of the upper stop segments 1032 blocks the support portion 304 and the second positioning segment 3052 on the same side; the other upper stop segment 1032 maintains a distance from the first inner wall 30531 and the second inner wall 30532 on the same side, that is, the other upper stop segment 1032 maintains a distance from the support portion 304 and the second positioning segment 3052 on the same side. In other embodiments, along the left-right direction, the left upper stop segment 1032 is located between the first inner wall 30531 and the left second positioning segment 3052, that is, the left upper stop segment 1032 is located between the support portion 304 and the left second positioning segment 3052; the right upper stop segment 1032 is located between the first inner wall 30531 and the right second positioning segment 3052, that is, the right upper stop segment 1032 is located between the support portion 304 and the right second positioning segment 3052; the two upper stop segments The upper stop segments 1032 are located on the left and right sides of the first inner wall 30531, that is, the two upper stop segments 1032 are located on the left and right sides of the support portion 304. The two upper stop segments 1032 may also simply prevent the two first inner walls 30531 from moving left and right, or they may simply prevent the support portion 304 from moving left and right. Both upper stop segments 1032 maintain a distance from the two first inner walls 30531, and both upper stop segments 1032 maintain a distance from the two second positioning segments 3052. In other embodiments, the upper stop segments 1032 may also cooperate independently with the second positioning segments 3052. For example, several positioning holes (not shown) are recessed backward along the second positioning segment 3052, and the upper stop segments 1032 and the positioning holes are interlocked and fixed.

[0039] like Figure 13 and Figure 16 As shown, the two rear positioning parts 306 are arranged in the left-right direction. The rear positioning parts 306 enter the locking part 2012, so that the locking part 2012 restricts the vertical and horizontal displacement of the rear positioning parts 306. In other embodiments, only one rear positioning part 306 may be provided and fixedly connected to the locking part 2012. Of course, the rear positioning part 306 may also be arranged in the vertical direction.

[0040] like Figures 13 to 14 As shown, each second connecting rib 307 is integrally connected to a front positioning part 305 and a rear positioning part 306. When viewed from the left and right direction, the projection of the pulled part 303 in the up and down direction is located between the projections of the two second connecting ribs 307. In the left and right direction, the second connecting ribs 307 and the pulled part 303 maintain a distance to avoid interference between the second connecting ribs 307 and the pulled part 303.

[0041] like Figures 13 to 14As shown, each third connecting rib 308 connects two rear positioning parts 306, which helps to strengthen the two rear positioning parts 306 and ensure the stability of the distance between the two rear positioning parts 306, ensuring the precise fit between the two rear positioning parts 306 and the two locking parts 2012 respectively. On this basis, the third connecting rib 308 is located in front of the front surface 2011, preventing the third connecting rib 308 from moving backward, which helps to further achieve stable positioning of the housing 20 on the locking member 30 in the front-rear direction. Observed in the front-rear direction, the projection of the pulled part 303 in the vertical direction is located between the projection of the support part 304 and the projection of the third connecting rib 308. In the front-rear direction, the third connecting rib 308 maintains a distance from the pulled part 303. In the vertical direction, the upper surface of the fastening part 3032 is higher than the lower surface of the third connecting rib 308. When the pulling member 40 is pulled, the pulling member 40 abuts against the upper surface of the fastening part 3032 and the lower surface of the third connecting rib 308 respectively.

[0042] In summary, the electrical connector 100 of the present invention has the following main beneficial effects: (1) By detachably connecting the locking element 30 to the insulating body 10 and the housing 20, when the locking element 30 is damaged, only the locking element 30 needs to be replaced. The insulating body 10 and the terminal T are not affected at all. The locking element 30 is a simple auxiliary structure with simple mold and less material, which helps to save material costs.

[0043] (2) Two locking parts 103 are located on the left and right sides of the support part 304 respectively, preventing the support part 304 from moving in the left and right direction. The locking part 103 includes a front stop section 1031 connected to the upper end face 1012 and an upper stop section 1032 located behind the front stop section 1031. The upper stop section 1032 maintains a distance from the upper end face 1012. The upper stop section 1032 is located above the first positioning section 3051, preventing the first positioning section 3051 from moving upward. The front stop section 1031 is located in front of the first positioning section 3051, preventing the first positioning section 3051 from moving forward. The upper end face 1012 abuts against the first positioning section 3051 upward. The two front positioning parts 305 are located on the left and right sides of the support part 304 respectively, and are integrally connected. The support part 304 is connected to the upper end face 1012, which limits the front positioning part 305, thereby indirectly limiting the support part 304 and ensuring the stability of the locking member 30 when unlocking. The two locking parts 103 are located on the left and right sides of the connecting part 302, respectively, to prevent the connecting part 302 from moving in the left and right direction, which strengthens the limiting effect of the locking member 30 on the insulating body 10. Not only are the two locking parts 103 located on the left and right sides of the support part 304, but they are also located on the left and right sides of the connecting part 302. Compared with the two locking parts 103 being located only on the left and right sides of the support part 304, this increases the force-bearing area of ​​the two locking parts 103 that stop the locking member 30, thus preventing damage to the locking member 30.

[0044] (3) The locking member 30 includes two rear positioning parts 306 on the left and right sides and a third connecting rib 308 connecting the two rear positioning parts 306. The third connecting rib 308 helps to strengthen the strength of the two rear positioning parts 306 and ensure the stability of the distance between the two rear positioning parts 306, and ensures the precise cooperation between the two rear positioning parts 306 and the two locking parts 2012 respectively. On this basis, the front surface 2011 is located behind the third connecting rib 308, blocking the third connecting rib 308 from moving backward, which helps to further realize the stable positioning of the locking member 30 in the front and rear directions of the housing 20. Compared to not having a third connecting rib 308, where the pulling member 40 directly abuts against the upper surface of the fastening part 3032 and the wall of the through hole 2013, by setting the third connecting rib 308 in front of the front surface 2011, the pulling member 40 abuts against the upper surface of the fastening part 3032 and the lower surface of the third connecting rib 308 respectively. Since the distance from the fastening part 3032 to the third connecting rib 308 is less than the distance from the fastening part 3032 to the front surface 2011, the inclination of the pulling member 40 portion from the upper surface of the fastening part 3032 to the lower surface of the third connecting rib 308 is greater than the inclination of the pulling member 40 portion from the upper surface of the fastening part 3032 to the wall of the through hole 2013. Furthermore, since the pulled part 303 moves downward under the pulling force of the pulling member 40, the pulling member 40 can pull the pulled part 303 with a relatively small pulling force, allowing the locking member 30 to be easily lifted and unlocked.

[0045] (4) The support part 304 and the second positioning part 3052 are integrally connected to the left and right sides of the first positioning section 3051 respectively. The thickness of the second positioning section 3052 in the vertical direction is greater than the thickness of the first positioning section 3051. The first positioning section 3051 is thinner, which reduces the pulling force on the connection between the support part 304 and the connecting part 302 and is conducive to the sway of the connecting part 302. The second positioning section 3052 is thicker, which is conducive to improving the local strength of the locking part 30 and is also conducive to the upper stop section 1032 stopping the second positioning section. 3052 moves to the left or right; the upper stop segment 1032 is located above the first positioning segment 3051, preventing the first positioning segment 3051 from moving upward; the upper stop segment 1032 is located between the support part 304 and the second positioning segment 3052, preventing the support part 304 and / or the second positioning segment 3052 from moving left or right; the front stop segment 1031 is located in front of the first positioning segment 3051, preventing the first positioning segment 3051 from moving forward, indirectly limiting the support part 304 and ensuring the stability of the locking fastener 30 when unlocking.

[0046] (5) The front stop section 1031 of the locking part 103 is located in front of the front positioning part 305, which stops the front positioning part 305 from moving forward. The locking part 2012 positions the rear positioning part 306. When the pull strap pulls the locking part 30, it can ensure that the locking part 30 is stably set between the insulating body 10 and the housing 20, and prevent the locking part 30 from falling off.

[0047] (6) The first connecting rib K is integrally connected to the two locking parts 103, which helps to strengthen the strength of the two locking parts 103 and reduce the deformation of the locking parts 103 in the left and right direction. In the up and down direction, the bottom surface 3022 and the first connecting rib K maintain a distance, avoiding interference between the bottom surface 3022 and the first connecting rib K. At the same time, it is also conducive to the locking fastener 30 being able to be lifted smoothly and unlocked from the docking connector 200.

[0048] (7) The abutting part 3033 and the fastening part 3032 are spaced apart to form a through groove 3035. The through hole 3034 and the through groove 3035 are connected to each other. When the pulling member 40 passes through the through hole 3034 and is fixed with the fastening part 3032, the pulling member 40 can pass through the through groove 3035 to exit the pulled part 303. Compared with the absence of the abutting part 3033, a part of the pulling member 40 abuts the abutting part 3033, which is beneficial to provide positioning for the pulling member 40 when it passes through the pulled part 303, and avoids excessive vertical displacement of the pulling member 40 when it is pulled.

[0049] The above detailed description is only an illustration of a preferred embodiment of the present invention and is not intended to limit the patent scope of the present invention. Therefore, all equivalent technical changes made using the content of this invention's specification and illustrations are included within the patent scope of this invention.
