When the user pulls the unlocking member 12, the two unlocking parts 1212 of the unlocking member 12 release the connection between the buckle grooves 1122 of the two buckle protrusions 112 and the line-end buckle parts 1211 of the two unlocking arms 121 and the board-end connector 2, respectively, so that the line-end connector 1 and the board-end connector 2 are in an unlocked state, thereby making the line-end connector 1 detachable from the board-end connector 2.

[0025] Please also read Figure 5 and Figure 6 , is a three-dimensional diagram of a board-side connector according to an embodiment of the present application and Figure 5The cross-sectional view along the line B-B' in the figure; as shown in the figure, the board-end connector 2 of this embodiment includes a board-end connector body 20 and a board-end housing 21, the board-end housing 21 has a board-end accommodating portion 211 and two snap-fitting slots 212, the board-end accommodating portion 211 has a board-end opening 2111 on one side of the first direction X, the two snap-fitting slots 212 are relatively arranged on both sides of the board-end accommodating portion 211, and the board-end connector body 20 is arranged in the board-end accommodating portion 211. The side walls 212a of the two snap-fitting slots 212 in the second direction Y and away from the board-end accommodating portion 211 also have board-end snap-fitting portions 2121 respectively.

[0026] See also Figure 3 and Figure 4 When the line-end connector 1 is connected to the board-end connector 2, the two buckle protrusions 112 of the line-end connector 1 enter the two buckle slots 212 respectively, and the two board-end buckle parts 2121 of the board-end connector 2 are respectively located in the buckle grooves 1122 of the two buckle protrusions 112. The two board-end buckle parts 2121 restrict the movement of the line-end buckle parts 1211 of the two unlocking arms 121 located in the two buckle protrusions 112 in the first direction X and the second direction Y, so that the line-end connector 1 and the board-end connector 2 are in a locked state. In addition, the unlocking parts 1212 of the two unlocking arms 121 located in the two buckle protrusions 112 respectively abut against the two board-end buckle parts 2121 of the board-end connector 2, so that the line-end connector 1 and the board-end connector 2 are in an unlocked state.

[0027] The following details the structure of the line-end connector 1 and the board-end connector 2. Figure 1 , Figure 2 and Figure 4 As shown, the two buckle protrusions 112 of the wire end housing 11 of the wire end connector 1 respectively have an accommodating groove 1123 extending along the first direction X, the accommodating groove 1123 passes through the first end 112a and the second end 112b of the buckle protrusion 112, and the accommodating groove 1123 is connected to the corresponding buckle groove 1122. The two unlocking arms 121 of the unlocking member 12 are movably disposed in the corresponding accommodating groove 1123, and the two unlocking arms 121 of the unlocking member 12 can move in the corresponding accommodating groove 1123.

[0028] Please also read Figure 7 ,yes Figure 4An enlarged view of area A in the middle; as shown in the figure, the snap groove 1122 has a first limiting side wall 11221 and a second limiting side wall 11222 in the first direction X, the second limiting side wall 11222 is farther away from the line end accommodating portion 111 than the first limiting side wall 11221, the first limiting side wall 11221 of the present embodiment is inclined relative to the first direction X, the second limiting side wall 11222 is orthogonal to the first direction X, and a distance D1 from one end of the first limiting side wall 11221 close to the line end accommodating portion 111 to an outer surface 1121 of the snap protrusion 112 in the second direction Y and away from the line end accommodating portion 111 is greater than a distance from one end of the first limiting side wall 11221 away from the line end accommodating portion 111 to an outer surface 1121 of the snap protrusion 112 in the second direction Y and away from the line end accommodating portion 111. In this embodiment, the end of the first limiting side wall 11221 away from the wire end accommodating portion 111 and the outer surface 1121 of the buckle protrusion 112 in the second direction Y and away from the wire end accommodating portion 111 are located on the same plane, so the distance between the end of the first limiting side wall 11221 away from the wire end accommodating portion 111 and the outer surface 1121 of the buckle protrusion 112 in the second direction Y and away from the wire end accommodating portion 111 is zero, so it is not Figure 7 Of course, the distance between the end of the first limiting side wall 11221 away from the wire end receiving portion 111 and the outer surface 1121 of the buckle protrusion 112 in the second direction Y and away from the wire end receiving portion 111 may also be greater than zero, but must be less than the distance D1 between the end of the first limiting side wall 11221 close to the wire end receiving portion 111 and the outer surface 1121 of the buckle protrusion 112 in the second direction Y and away from the wire end receiving portion 111.

[0029] The shape of the wire end snap-in portion 1211 of the two unlocking arms 121 is consistent with the shape of the snap-in groove 1122. The wire end snap-in portion 1211 is a notch. The wire end snap-in portion 1211 has a first limiting side edge 12111 and a second limiting side edge 12112 in the first direction X. The first limiting side edge 12111 corresponds to the first limiting side wall 11221, and the second limiting side edge 12112 corresponds to the second limiting side wall 11222.

[0030] like Figure 3 , Figure 4 and Figure 5As shown, the board end buckle portion 2121 of the two buckle slots 212 of the board end shell 21 respectively has a clearance opening 21211 and a buckle spring piece 21212, the clearance opening 21211 penetrates the buckle slot 212 in the second direction Y and away from the side wall 212a of the board end accommodating portion 211, one end of the buckle spring piece 21212 is connected to the side of the clearance opening 21211 in the first direction X and close to the board end accommodating portion 211, the buckle spring piece 21212 extends in the direction away from the board end accommodating portion 211, and the buckle spring piece 21212 is inclined relative to the side wall 212a of the buckle slot 212 in the second direction Y and away from the board end accommodating portion 211 and bends into the buckle slot 212.

[0031] When the wire-end connector 1 is connected to the board-end connector 2, the two snap-in protrusions 112 of the wire-end connector 1 respectively enter the two snap-in slots 212, and the two snap-in springs 21212 of the board-end connector 2 are respectively located in the snap-in grooves 1122 of the two snap-in protrusions 112, and are located on one side of the first limiting side wall 11221. The snap-in springs 21212 of the two board-end snap-in parts 2121 respectively correspond to the first limiting side edges 12111 of the two wire-end snap-in parts 1211, so that the snap-in springs 21212 of the two board-end snap-in parts 2121 respectively limit the movement of the two snap-in protrusions 112 and the two unlocking arms 121 in the second direction Y, thereby limiting the movement of the wire-end connector 1 relative to the board-end connector 2 in the second direction Y.

[0032] The end faces of the other ends of the snap springs 21212 of the two board-end snap parts 2121 respectively correspond to the second limiting side walls 11222 of the two snap grooves 1122 and the second limiting side edges 12112 of the two line-end snap parts 1211. At this time, the snap springs 21212 are inclined relative to the snap slots 212 in the second direction Y and away from the side walls 212a of the board-end accommodating portion 211 and are bent toward the snap slots 212, that is, the snap springs 21212 are located in the snap grooves 1122. In this way, the end faces of the other ends of the snap springs 21212 of the two board-end snap parts 2121 respectively limit the movement of the two snap protrusions 112 and the two unlocking arms 121 in the first direction X, thereby limiting the movement of the line-end connector 1 relative to the board-end connector 2 in the first direction X, thereby preventing the line-end connector 1 from detaching from the board-end connector 2.

[0033] like Figure 2 and Figure 4As shown, the unlocking parts 1212 of the two unlocking arms 121 of the unlocking member 12 are located on the side of the wire end buckle part 1211 away from the wire end accommodating part 111, and the unlocking parts 1212 are connected to the second limiting side edge 12112. When the wire end connector 1 is to be detached from the board end connector 2, the user pulls the unlocking member 12, and the unlocking member 12 moves along the first direction X and away from the board end connector 2. The unlocking parts 1212 of the two unlocking arms 121 pass through the buckling grooves 1122 of the two buckling protrusions 112 respectively, and the unlocking parts 1212 of the two unlocking arms 121 move and protrude from the first limiting side walls 11221 of the two buckling grooves 1122 respectively, and the two unlocking parts 1212 push the two board end buckle parts 1121 to move out of the first limiting side walls 11221 of the two buckling protrusions 112. The snap spring piece 21212 of 2121 is bent outward of the snap slot 212, so that the snap spring piece 21212 and the snap slot 212 are respectively in the second direction Y and away from the side wall 212a of the board end accommodating portion 211. At the same time, the unlocking member 12 drives the wire end housing 11 accommodating the wire end connector body 10 to move away from the board end connector 2, and the two snap protrusions 112 are separated from the two snap slots 212 of the board end housing 21, so that the wire end connector 1 is completely separated from the board end connector 2. In this embodiment, the unlocking portion 1212 of the two unlocking arms 121 is a plane orthogonal to the second direction Y.

[0034] In this embodiment, if Figure 7 As shown, the second limiting side edges 12112 of the two line end buckling portions 1211 of the two unlocking arms 121 of this embodiment are inclined relative to the second direction Y, and a distance D2 from the side of the second limiting side edge 12112 close to the first limiting side edge 12111 to the side of the unlocking arm 121 in the second direction Y is greater than a distance from the side of the second limiting side edge 12112 connected to the unlocking portion 1212 to the side of the unlocking arm 121 in the second direction Y. In this embodiment, the side of the second limiting side edge 12112 connected to the unlocking portion 1212 and the side of the unlocking arm 121 in the second direction Y are located on the same plane, so the distance between the side of the second limiting side edge 12112 connected to the unlocking portion 1212 and the side of the unlocking arm 121 in the second direction Y is zero, so it is not Figure 7 Of course, the distance between the side of the second limiting side 12112 connected to the unlocking portion 1212 and the side of the unlocking arm 121 in the second direction Y may also be greater than zero, but must be less than the distance D2 from the side of the second limiting side 12112 close to the first limiting side 12111 to the side of the unlocking arm 121 in the second direction Y. As can be seen from the above, the second limiting side 12112 is inclined relative to the second limiting side wall 11222 of the buckle groove 1122, and the inclination direction of the second limiting side 12112 is opposite to the inclination direction of the first limiting side wall 11221, and the second limiting side 12112 is located in the accommodating groove 1123.

[0035] Please also read Figure 8 , Fig. 9 and Fig.10 , is an actuation stereogram, a partial actuation cross-sectional diagram, and an actuation schematic diagram of the connector assembly of an embodiment of the present application; as shown in the figure, when the unlocking member 12 moves in a direction away from the board-end connector 2, the second limiting side edges 12112 of the two unlocking arms 121 respectively contact the end surfaces of the buckle springs 21212 of the two board-end buckle portions 2121, and as the unlocking member 12 continues to move in a direction away from the board-end connector 2, the buckle springs 21212 of the two board-end buckle portions 2121 are The end faces of the latch spring piece 21212 are respectively bent along the second limiting side edges 12112 of the two unlocking arms 121 toward the outside of the latch slot 212, and finally the unlocking parts 1212 of the two unlocking arms 121 are in contact with the latch spring pieces 21212 of the two board end latch parts 2121. At this time, the latch spring pieces 21212 of the two board end latch parts 2121 are bent to the greatest extent toward the outside of the latch slot 212, so the second limiting side edges 12112 of the two unlocking arms 121 have a guiding function.

[0036] In this embodiment, the second ends 112b of the two buckle protrusions 112 away from the wire end receiving portion 111 have guiding inclined surfaces 1124 on the first direction X and the second direction Y, respectively. The guiding inclined surfaces 1124 are provided to reduce the size of the second ends 112b of the two buckle protrusions 112, so that the two buckle protrusions 112 can be easily inserted into the two buckle slots 212. The inclination direction of the guiding inclined surfaces 1124 of the second ends 112b of the two buckle protrusions 112 in the second direction Y and away from the board end receiving portion 211 is the same as the inclination direction of the buckle spring pieces 21212 of the two board end buckle portions 2121.

[0037] When the second ends 112b of the two buckling protrusions 112 pass through the two board end buckling portions 2121, the second ends 112b of the two buckling protrusions 112 move relative to the buckling spring pieces 21212 of the two board end buckling portions 2121 in the second direction Y and away from the guiding inclined surface 1124 of the board end accommodating portion 211, and push the buckling spring pieces 21212 of the two board end buckling portions 2121 to bend outside the buckling slots 212, so that the two buckling protrusions 112 smoothly pass through the buckling spring pieces 21212 of the two board end buckling portions 2121 and are disposed in the two buckling slots 212. The buckling ends 121b of the two unlocking arms 121 of the present embodiment away from the wire end accommodating portion 111 further have chamfers 1213 on opposite sides in the second direction Y, so that the buckling ends 121b of the two unlocking arms 121 will not protrude from the two buckling protrusions 112.

[0038] In one embodiment, if Figure 2 and Figure 4As shown, the wire end connector 1 further includes two elastic members 14, which are respectively disposed in two accommodating grooves 1123, one end of the two elastic members 14 respectively abuts against the connecting ends 121a of the two unlocking arms 121, and the other ends of the two elastic members 14 respectively abut against the first ends 112a of the two buckling protrusions 112, and when the two unlocking arms 121 are pushed to approach the wire end accommodating portion 111 along the first direction X, the two unlocking arms 121 respectively compress the two elastic members 14. When the two unlocking arms 121 stop being pushed to approach the wire end accommodating portion 111 along the first direction X, the compressed two elastic members 14 are released, and the elastic force of the two elastic members 14 respectively pushes the two unlocking arms 121 to move in the direction away from the wire end accommodating portion 111 along the first direction X, so that the two unlocking arms 121 automatically return to their original positions, and then the unlocking member 12 automatically returns to its original position.

[0039] In this embodiment, if Figure 2 and Figure 4 As shown, the connecting ends 121a of the two unlocking arms 121 respectively have positioning columns 1214, and the positioning columns 1214 extend along the first direction X and in a direction away from the buckle end 121b. One end of the positioning column 1214 away from the buckle end 121b is passed through the corresponding elastic member 14, and the two elastic members 14 are positioned to abut against the connecting ends 121a of the two unlocking arms 121 through the setting of the positioning columns 1214. The two buckle protrusions 112 of this embodiment also have limiting posts 1125 respectively, which are arranged in the corresponding receiving grooves 1123 and located at the first ends 112a of the corresponding buckle protrusions 112. The two limiting posts 1125 of this embodiment extend along the third direction Z, and the two ends of the two limiting posts 1125 are respectively connected to the two opposite side walls of the two receiving grooves 1123 in the third direction Z. The other ends of the two elastic members 14 are respectively abutted against the two limiting posts 1125, and the two elastic members 14 are positioned to abut against the first ends 112a of the two buckle protrusions 112 through the setting of the limiting posts 1125. The third direction Z is orthogonal to the first direction X and the second direction Y. The elastic member 14 of this embodiment is a spring.

[0040] The two limiting posts 1125 of this embodiment are movably disposed on the two buckling protrusions 112 , respectively, which also means that the two limiting posts 1125 can be assembled to the two buckling protrusions 112 and can also be removed from the two buckling protrusions 112 .

[0041] The two receiving grooves 1123 of this embodiment have two side walls that are opposite to each other in the third direction Z, respectively, with through holes 11231, and the two ends of the two limiting posts 1125 are respectively disposed in the two through holes 11231 of the two receiving grooves 1123.

One side of the circuit board 101 having the plurality of contact pads 1011 is exposed from the wire end insulating body 103.

[0045] When the wire end connector body 10 of the present embodiment is disposed in the wire end accommodating portion 111 of the wire end housing 11, the wire end insulating body 103 is located in the wire end accommodating portion 111, the circuit board 101 has a side with multiple contact pads 1011 protruding from the wire end opening 1111 of the wire end housing 11, and multiple cables 102 pass through the side of the wire end housing 11 away from the wire end opening 1111. The wire end insulating body 103 of the present embodiment also has positioning grooves 1031 on both sides opposite to each other in the second direction Y, and the wire end accommodating portion 111 of the wire end housing 11 also has positioning protrusions 1112 on both side walls opposite to each other in the second direction Y. The positioning protrusions 1112 are located in the positioning grooves 1031 to fix the wire end insulating body 103 in the wire end accommodating portion 111 of the wire end housing 11, thereby increasing the stability of the connection between the wire end housing 11 and the wire end insulating body 103. Figure 4 As shown, the circuit board 101 of this embodiment further has interference protrusions 1013 on two opposite sides in the second direction Y, and the interference protrusions 1013 interfere with the wire terminal insulation body 103 to increase the connection stability between the circuit board 101 and the wire terminal insulation body 103. The wire terminal insulation body 103 and the wire terminal housing 11 of this embodiment are both formed by injection molding.

[0046] like Figure 5 and Figure 6 As shown, the board-end connector body 20 of this embodiment includes a board-end insulating body 201 and two terminal modules 202, the board-end insulating body 201 has a slot 2011, and the two terminal modules 202 are stacked and arranged in the slot 2011 along the third direction Z. The board-end accommodating portion 211 of the board-end housing 21 has a notch 213 on the bottom surface in the third direction Z, and the two terminal modules 202 respectively have a plurality of terminals 2021, one end of the plurality of terminals 2021 is located in the slot 2011, and the other end of the plurality of terminals 2021 is exposed from the notch 213 to be connected to an external circuit board.

[0047] The two snap-in slots 212 of the board end housing 21 of this embodiment also have a top surface 212b in the third direction Z, one side of the top surface 212b is connected to one side of the side wall 212a, and the side wall 212a and the top surface 212b are orthogonal to each other. In this embodiment, the inner sides of the two snap-in slots 212 of the board end housing 21 also respectively have an extended support piece 212c extending along the second direction, one side of the extended support piece 212c is connected to the other side of the side wall 212a, and corresponds to the top surface 212b, that is, the extended support piece 212c and the top surface 212b are spaced apart in the third direction, and the other side of the extended support piece 212c is suspended. When the two snap-in protrusions 112 of the line end connector 1 are respectively arranged in the two snap-in slots 212, the extended support piece 212c supports the corresponding snap-in protrusion 112. There is a first angle A1 between the extended support piece 212c and the side wall 212a. In the present embodiment, the first angle A1 is 90 degrees, that is, the extended support piece 212c is orthogonal to the side wall 212a. Of course, the first angle A1 can also be less than 90 degrees, which reduces the distance between the extended support piece 212c and the top surface 212b. When the two buckle protrusions 112 of the wire end connector 1 are respectively disposed in the two buckle slots 212, the movement of the buckle protrusion 112 in the third direction Z is limited by the extended support piece 212c and the top surface 212b.

[0048] The top surface of the board-end receiving portion 211 of the board-end housing 21 also has two positioning pieces 214, and the two positioning pieces 214 extend into the board-end receiving portion 211 along the third direction Z. The top surface of the board-end insulating body 201 of the board-end connector body 20 in the third direction Z also has two positioning grooves 2012, and the two positioning grooves 2012 extend along the third direction Z. When the board-end connector body 20 is disposed in the board-end receiving portion 211, the two positioning pieces 214 are respectively disposed in the two positioning grooves 2012 to position the board-end connector body 20 in the board-end receiving portion 211. In this embodiment, the two positioning pieces 214 respectively have a second angle A2 with the top surface of the board-end receiving portion 211 of the board-end housing 21. The angle of the second angle A2 in this embodiment is equal to 90 degrees, so the two positioning pieces 214 are respectively orthogonal to the top surface of the board-end receiving portion 211 of the board-end housing 21. In other embodiments, the second angle A2 is less than 90 degrees, so that the two positioning pieces 214 respectively abut against the side walls of the two positioning grooves 2012 close to the buckle slots 212 , thereby effectively fixing the board-end connector body 20 in the board-end accommodating portion 211 .

[0049] In summary, the present application provides a board-end connector and a connector assembly, wherein the snap slot of the board-end connector is located on one side of the board-end connector body, and the snap slot is provided for two snap protrusions and two unlocking arms of the wire-end connector. The two board-end snap parts and the snap grooves of the two snap protrusions and the wire-end snap parts and unlocking parts of the two unlocking arms move in the horizontal direction, thereby not increasing the thickness of the board-end connector in the vertical direction, thereby allowing the board-end connector to develop towards thinness.

[0050] The buckle slot of the board-end connector of the present application also has an extended support sheet, which can support the buckle protrusion so that the buckle protrusion can be stably arranged in the buckle slot. The board-end accommodating portion of the board-end connector of the present application also has a positioning sheet, and the board-end connector body also has a positioning groove. The positioning sheet is arranged in the positioning groove, so that the board-end connector body is stably arranged in the board-end accommodating portion.
