Description

[0001] This application is a divisional application of the invention patent application with the application date of December 16, 2020, the application number of 202011489361.9, and the invention title of "Board-end Connector and Connector Assembly". Technical Field

[0002] This application relates to the technical field of connectors, and particularly to a board-end connector and a connector assembly. Background Art

[0003] Currently, a board-end connector generally has a board-end connector body and a locking portion located on the top surface of the board-end connector body. When a wire-end connector is connected to the board-end connector, the wire-end connector is connected to the locking portion of the board-end connector through a pull-tape unlocking structure. The locking portion is arranged on the top surface of the board-end connector body, which increases the thickness of the board-end connector and is not conducive to the development of thinness. In addition, the structure of the locking portion is relatively complex due to the pull-tape unlocking structure, and the manufacturing is relatively complicated. Summary of the Invention

[0004] The present invention provides a board-end connector and a connector assembly to solve the problem that the locking portion of the current board-end connector is located on the top surface of the board-end connector body, making the board-end connector unable to be thinned.

[0005] To solve the above technical problems, the present invention is implemented as follows: The present invention provides a board-end connector, which includes: a board-end connector body; and a board-end housing having a board-end accommodation portion and a snap slot. Among them: the board-end accommodation portion accommodates the board-end connector body, the snap slot is located on one side of the board-end accommodation portion, and the board-end snap portion is provided on the side wall of the snap slot away from the board-end accommodation portion, so that when the snap projection of the wire-end connector enters the snap slot in a first direction, the board-end snap portion is located in the snap groove of the snap projection to limit the movement of the snap projection in the first direction and a second direction, and the first direction and the second direction are orthogonal; the inner side of the snap slot has a top surface and an extended support piece spaced apart in a third direction to limit the movement of the snap projection of the wire-end connector in the third direction when the snap projection enters the snap slot in the first direction, and the extended support piece supports the snap projection, and the third direction is orthogonal to the first direction and the second direction respectively.

[0006] In another embodiment, a connector assembly is provided, which includes: a board - end connector as described above, with the number of snap - slots being two; and a wire - end connector, including a wire - end connector body, a wire - end housing accommodating the wire - end connector body, and an unlocking member. The wire - end housing has two snap - protrusions, and the outer surfaces of the two snap - protrusions in the second direction respectively have snap - grooves. The unlocking member is disposed on one side of the wire - end housing. The unlocking member has two unlocking arms, which are respectively disposed in the two snap - protrusions. The outer sides of the two unlocking arms in the second direction respectively have unlocking portions. Wherein, when the wire - end connector is connected to the board - end connector, the two snap - protrusions respectively enter the two snap - slots, and the two snap - slots are located in the snap - grooves of the two snap - protrusions. When the unlocking member moves in a direction away from the board - end connector, the unlocking portions of the two unlocking arms pass through the snap - grooves of the two snap - protrusions and push the two board - end snap - portions.

[0007] The snap - slots of the board - end connector of the present invention are located on one side of the board - end connector body. The snap - slots are for the two snap - protrusions and the two unlocking arms of the wire - end connector to be disposed. The two board - end snap - portions and the snap - grooves of the two snap - protrusions and the unlocking portions of the two unlocking arms act in the horizontal direction. In this way, the thickness of the board - end connector in the vertical direction will not be increased, enabling the board - end connector to develop towards being thinner.

[0009] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without making creative efforts shall fall within the protection scope of the present application.

[0010] Please refer to Figure 1 and Figure 2 , which are a perspective view, an exploded view, and a schematic diagram of a wire-end connector according to an embodiment of the present application; as shown in the figure, the wire-end connector 1 of this embodiment includes a wire-end connector body 10, a wire-end housing 11, and an unlocking member 12. The wire-end housing 11 has a wire-end accommodating portion 111 and two buckle protrusions 112. The wire-end accommodating portion 111 has a wire-end opening 1111 on the end surface in the first direction X. The two buckle protrusions 112 are oppositely arranged on both sides of the wire-end accommodating portion 111. The two buckle protrusions 112 respectively have a first end 112a and a second end 112b. The first ends 112a of the two buckle protrusions 112 are close to the side of the wire-end housing 11 away from the wire-end opening 1111. The second ends 112b of the two buckle protrusions 112 respectively protrude from one end of the wire-end accommodating portion 111 having the wire-end opening 1111 in the first direction X.

[0011] On the outer surfaces 1121 of the two buckle protrusions 112 in the second direction Y, there are respectively buckle grooves 1122. The buckle grooves 1122 of the two buckle protrusions 112 are respectively located between the wire-end accommodating portion 111 and the second ends 112b of the two buckle protrusions 112. The wire-end connector body 10 is arranged in the wire-end accommodating portion 111 of the wire-end housing 11. The unlocking member 12 has two opposite unlocking arms 121. The unlocking member 12 is arranged on the side of the wire-end housing 11 away from the wire-end opening 1111. The two unlocking arms 121 are respectively movably arranged in the two buckle protrusions 112. The two unlocking arms 121 respectively have a connecting end 121a and a buckling end 121b. The connecting ends 121a of the two unlocking arms 121 are respectively located at the first ends 112a of the two buckle protrusions 112. The buckling ends 121b of the two unlocking arms 121 are respectively located at the second ends 112b of the two buckle protrusions 112. The two unlocking arms 121 respectively protrude from one end of the wire-end accommodating portion 111 having the wire-end opening 1111 in the first direction X.

[0012] The two unlocking arms 121 also respectively have line end latching portions 1211 and unlocking portions 1212 on the outer sides of the line end accommodating portion 111 in the second direction Y and away from the line end. The line end latching portions 1211 of the two unlocking arms 121 respectively correspond to the latching grooves 1122 of the two latching protrusions 112. The unlocking portions 1212 of the two unlocking arms 121 are respectively located on one side of the latching grooves 1122 of the two latching protrusions 112. The unlocking portions 1212 of the two unlocking arms 121 are respectively farther from the line end accommodating portion 111 than the line end latching portions 1211 of the two unlocking arms 121, wherein the second direction Y is orthogonal to the first direction X.

[0013] Please refer to Figure 3 and Figure 4 for a perspective view of a connector assembly according to an embodiment of the present application and Figure 3 a cross-sectional view taken along line A-A' in ; as shown in the figure, when the line end connector 1 is connected to the board end connector 2 to form a connector assembly, the latching grooves 1122 of the two latching protrusions 112 of the line end connector 1 and the line end latching portions 1211 of the two unlocking arms 121 are respectively connected to the board end connector 2, that is, the line end connector 1 and the board end connector 2 are in a locked state. When the user pulls the unlocking member 12, the connection relationship between the latching grooves 1122 of the two latching protrusions 112 and the line end latching portions 1211 of the two unlocking arms 121 and the board end connector 2 is respectively released through the two unlocking portions 1212 of the unlocking member 12, so that the line end connector 1 and the board end connector 2 are in an unlocked state, and then the line end connector 1 is disengaged from the board end connector 2.

[0014] Please refer to Figure 5 and Figure 6 for a perspective view of a board end connector according to an embodiment of the present application and Figure 5 a cross-sectional view taken along line B-B' in ; 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 latching slots 212. The board end accommodating portion 211 has a board end opening 2111 on one side in the first direction X. The two latching slots 212 are oppositely arranged on both sides of the board end accommodating portion 211. The board end connector body 20 is arranged in the board end accommodating portion 211. The two latching slots 212 also respectively have board end latching portions 2121 on the outer sides of the side walls 212a of the board end accommodating portion 211 in the second direction Y and away from the board end accommodating portion 211.

[0015] Please refer back to Figure 3 and Figure 4When the wire - end connector 1 is connected to the board - end connector 2, the two snap - convex parts 112 of the wire - end connector 1 respectively enter the two snap - slots 212. The two board - end snap - parts 2121 of the board - end connector 2 are respectively located in the snap - grooves 1122 of the two snap - convex parts 112. The two board - end snap - parts 2121 restrict the movement of the wire - end snap - parts 1211 of the two unlocking arms 121 located in the two snap - convex parts 112 in the first direction X and the second direction Y, so that the wire - end connector 1 and the board - end connector 2 are in a locked state. In addition, by the unlocking parts 1212 of the two unlocking arms 121 located in the two snap - convex parts 112 respectively abutting against the two board - end snap - parts 2121 of the board - end connector 2, the wire - end connector 1 and the board - end connector 2 are in an unlocked state.

[0016] The structures of the wire - end connector 1 and the board - end connector 2 are described in detail below. As Figure 1 、 Figure 2 and Figure 4 shown, the two snap - convex parts 112 of the wire - end housing 11 of the wire - end connector 1 respectively have accommodation through - grooves 1123 extending along the first direction X. The accommodation through - grooves 1123 penetrate through the first end 112a and the second end 112b of the snap - convex part 112, and the accommodation through - grooves 1123 communicate with the corresponding snap - grooves 1122. The two unlocking arms 121 of the unlocking part 12 are movably arranged in the corresponding accommodation through - grooves 1123, and the two unlocking arms 121 of the unlocking part 12 can move in the corresponding accommodation through - grooves 1123.

[0017] Please refer to Figure 7 together, which is Figure 4 an enlarged view of area A in Figure 7The markings. Of course, 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 projection 112 in the second direction Y and away from the wire-end accommodating portion 111 can also be greater than zero, but it must be less than the distance D1 from the end of the first limiting side wall 11221 close to the wire-end accommodating portion 111 to the outer surface 1121 of the buckle projection 112 in the second direction Y and away from the wire-end accommodating portion 111.

[0018] The shapes of the wire-end buckling portions 1211 of the two unlocking arms 121 match the shapes of the buckle grooves 1122. The wire-end buckling portions 1211 are notches. The wire-end buckling portions 1211 have 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.

[0019] As Figure 3 , Figure 4 and Figure 5 As shown in, the board-end buckling portions 2121 of the two buckle slots 212 of the board-end housing 21 respectively have a relief opening 21211 and a buckle elastic piece 21212. The relief opening 21211 penetrates through the side wall 212a of the buckle slot 212 in the second direction Y and away from the board-end accommodating portion 211. One end of the buckle elastic piece 21212 is connected to the side edge of the relief opening 21211 in the first direction X and close to the board-end accommodating portion 211. The buckle elastic piece 21212 extends in the direction away from the board-end accommodating portion 211. The buckle elastic piece 21212 is inclined with respect 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.

[0020] When the wire-end connector 1 is connected to the board-end connector 2, the two buckle projections 112 of the wire-end connector 1 respectively enter the two buckle slots 212. The two buckle elastic pieces 21212 of the board-end connector 2 are respectively located in the buckle grooves 1122 of the two buckle projections 112 and on one side of the first limiting side wall 11221. The buckle elastic pieces 21212 of the two board-end buckling portions 2121 respectively correspond to the first limiting side edges 12111 of the two wire-end buckling portions 1211. In this way, the buckle elastic pieces 21212 of the two board-end buckling portions 2121 respectively limit the two buckle projections 112 and the two unlocking arms 121 from moving in the second direction Y, and further limit the wire-end connector 1 from moving relative to the board-end connector 2 in the second direction Y.

[0021] The end faces of the other ends of the buckle elastic pieces 21212 of the two board-end buckle parts 2121 respectively correspond to the second limiting side walls 11222 of the two buckle grooves 1122 and the second limiting side edges 12112 of the two wire-end buckle parts 1211. At this time, the buckle elastic pieces 21212 are inclined relative to the buckle slot 212 in the second direction Y and away from the side wall 212a of the board-end accommodation part 211 and are bent into the buckle slot 212, that is, the buckle elastic pieces 21212 are located in the buckle grooves 1122. In this way, the end faces of the other ends of the buckle elastic pieces 21212 of the two board-end buckle parts 2121 respectively limit the two buckle protrusions 112 and the two unlocking arms 121 from moving in the first direction X, and further limit the wire-end connector 1 from moving relative to the board-end connector 2 in the first direction X, so as to prevent the wire-end connector 1 from detaching from the board-end connector 2.

[0022] As Figure 2 shown in Figure 4 , 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 accommodation part 111, and the unlocking parts 1212 are connected to the second limiting side edges 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 in the first direction X and away from the board-end connector 2. The unlocking parts 1212 of the two unlocking arms 121 respectively pass through the buckle grooves 1122 of the two buckle protrusions 112, and the unlocking parts 1212 of the two unlocking arms 121 respectively move outwards and protrude from the first limiting side walls 11221 of the two buckle grooves 1122. The two unlocking parts 1212 respectively push the buckle elastic pieces 21212 of the two board-end buckle parts 2121 to bend outwards from the buckle slot 212, so that the buckle elastic pieces 21212 are respectively in the second direction Y with the buckle slot 212 and away from the side wall 212a of the board-end accommodation part 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 buckle protrusions 112 are separated from the two buckle slots 212 of the board-end housing 21, so that the wire-end connector 1 is completely detached from the board-end connector 2. In this embodiment, the unlocking parts 1212 of the two unlocking arms 121 are planes orthogonal to the second direction Y.

[0023] In this embodiment, as Figure 7As shown, the second limiting side 12112 of the two wire end buckle parts 1211 of the two unlocking arms 121 in this embodiment is inclined relative to the second direction Y. 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 is greater than the distance from the side where the second limiting side 12112 is connected to the unlocking part 1212 to the side of the unlocking arm 121 in the second direction Y. In this embodiment, the side where the second limiting side 12112 is connected to the unlocking part 1212 and the side of the unlocking arm 121 in the second direction Y are on the same plane. Therefore, the distance between the side where the second limiting side 12112 is connected to the unlocking part 1212 and the side of the unlocking arm 121 in the second direction Y is zero. So it is not marked on Figure 7 Of course, the distance between the side where the second limiting side 12112 is connected to the unlocking part 1212 and the side of the unlocking arm 121 in the second direction Y can also be greater than zero, but it 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. The inclination direction of the second limiting side 12112 is opposite to the inclination direction of the first limiting side wall 11221. The second limiting side 12112 is located in the accommodation through groove 1123.

[0024] Please refer to Figure 8 , Figure 9 and Figure 10 , which are the operating perspective view, partial operating cross-sectional view of the connector assembly in an embodiment of the present application, and the operating schematic diagram of the unlocking part and the buckle elastic piece. As shown in the figure, when the unlocking member 12 moves away from the board-end connector 2, the second limiting sides 12112 of the two unlocking arms 121 respectively contact the end faces of the buckle elastic pieces 21212 of the two board-end buckle parts 2121. As the unlocking member 12 continues to move away from the board-end connector 2, the end faces of the buckle elastic pieces 21212 of the two board-end buckle parts 2121 are respectively bent outward along the second limiting sides 12112 of the two unlocking arms 121 towards the buckle slot 212. Finally, the unlocking parts 1212 of the two unlocking arms 121 contact the buckle elastic pieces 21212 of the two board-end buckle parts 2121. At this time, the degree of bending of the buckle elastic pieces 21212 of the two board-end buckle parts 2121 outward towards the buckle slot 212 is the largest. Therefore, the second limiting sides 12112 of the two unlocking arms 121 have a guiding effect.

[0025] In this embodiment, the four surfaces of the second ends 112b of the two snap protrusions 112 away from the wire-end accommodating portion 111 respectively have guiding inclined surfaces 1124 in the first direction X and the second direction Y. By providing the guiding inclined surfaces 1124, the sizes of the second ends 112b of the two snap protrusions 112 are reduced, so that the two snap protrusions 112 can easily penetrate into the two snap slots 212 respectively. The inclination directions of the guiding inclined surfaces 1124 of the second ends 112b of the two snap protrusions 112 in the second direction Y and away from the board-end accommodating portion 211 are the same as the inclination directions of the snap elastic pieces 21212 of the two board-end snap portions 2121.

[0026] When the second ends 112b of the two snap protrusions 112 pass through the two board-end snap portions 2121, the guiding inclined surfaces 1124 of the second ends 112b of the two snap protrusions 112 in the second direction Y and away from the board-end accommodating portion 211 move relative to the snap elastic pieces 21212 of the two board-end snap portions 2121, and push the snap elastic pieces 21212 of the two board-end snap portions 2121 to bend outwards from the snap slots 212, so that the two snap protrusions 112 can smoothly pass through the snap elastic pieces 21212 of the two board-end snap portions 2121 and are arranged in the two snap slots 212. The two unlocking arms 121 of this embodiment also have chamfers 1213 on the opposite sides of the snap ends 121b away from the wire-end accommodating portion 111 in the second direction Y, so that the snap ends 121b of the two unlocking arms 121 do not protrude from the two snap protrusions 112.

[0027] In one embodiment, as Figure 2 shown in Figure 4 the wire-end connector 1 further includes two elastic members 14. The two elastic members 14 are respectively arranged in the two accommodating through grooves 1123. One ends of the two elastic members 14 respectively abut 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 snap protrusions 112. 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 pushing of the two unlocking arms 121 along the first direction X towards the wire-end accommodating portion 111 stops, the compressed two elastic members 14 are released, and the elastic forces of the two elastic members 14 respectively push the two unlocking arms 121 to move along the first direction X in the direction away from the wire-end accommodating portion 111, so that the two unlocking arms 121 automatically return to their original positions, and further the unlocking member 12 automatically returns to its original position.

[0028] In this embodiment, as Figure 2 shown in Figure 4As shown, the connecting ends 121a of the two unlocking arms 121 respectively have positioning posts 1214. The positioning posts 1214 extend along the first direction X and away from the buckling end 121b. One end of the positioning post 1214 away from the buckling end 121b penetrates through the corresponding elastic members 14. The positions where the two elastic members 14 abut against the connecting ends 121a of the two unlocking arms 121 are positioned by the positioning posts 1214. The two buckling convex members 112 of this embodiment also respectively have limiting posts 1125. The limiting posts 1125 are arranged in the corresponding accommodating through grooves 1123 and are located at the first ends 112a of the corresponding buckling convex members 112. The two limiting posts 1125 of this embodiment extend along the third direction Z. Two ends of the two limiting posts 1125 are respectively connected to two opposite side walls of the two accommodating through grooves 1123 in the third direction Z. The other ends of the two elastic members 14 respectively abut against the two limiting posts 1125. The positions where the two elastic members 14 abut against the first ends 112a of the two buckling convex members 112 are positioned by 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.

[0029] The two limiting posts 1125 of this embodiment are respectively movably arranged on the two buckling convex members 112, which also means that the two limiting posts 1125 can be assembled on the two buckling convex members 112 and can also be removed from the two buckling convex members 112.

[0030] The two opposite side walls of the two accommodating through grooves 1123 in the third direction Z respectively have through holes 11231. Two ends of the two limiting posts 1125 are respectively arranged in the two through holes 11231 of the two accommodating through grooves 1123. The first ends 112a of the two buckling convex members 112 also respectively have elastic member insertion holes 1126. The two elastic members 14 can be respectively inserted into the two accommodating through grooves 1123 from the elastic member insertion holes 1126 of the two buckling convex members 112, achieving convenient assembly. Usually, the two elastic members 14 are respectively arranged in the two accommodating through grooves 1123 through the elastic member insertion holes 1126 first, and then the two limiting posts 1125 are respectively arranged in the two accommodating through grooves 1123 through the two through holes 11231. The two limiting posts 1125 are located in the elastic member insertion holes 1126 to prevent the elastic members 14 from passing through the elastic member insertion holes 1126.

[0031] Such as Figure 1 and Figure 2As shown, the unlocking member 12 of this embodiment further has a snap connection piece 122, and both ends of the snap connection piece 122 are respectively connected to the connection ends 121a of the two unlocking arms 121. When the unlocking member 12 is disposed on the side of the wire end housing 11 away from the wire end opening 1111, the snap connection piece 122 is located on the side of the wire end housing 11 away from the wire end opening 1111. The side of the wire end housing 11 away from the wire end opening 1111 of this embodiment further has a relief notch 113, and the first ends 112a of the two snap projections 112 are located on both sides of the relief notch 113. When the unlocking member 12 is disposed on the side of the wire end housing 11 away from the wire end opening 1111, the snap connection piece 122 can be located in the relief notch 113 to prevent the snap connection piece 122 from protruding from the side of the wire end housing 11 away from the wire end opening 1111. As Figure 4 shown, the surfaces of the first ends 112a of the two snap projections 112 in the second direction Y and close to the relief notch 113 have connection openings 1127, and the connection openings 1127 communicate with the accommodation through grooves 1123. The connection parts of the two unlocking arms 121 and the snap connection piece 122 are respectively located in the connection openings 1127 of the two snap projections 112.

[0032] As Figure 1 、 Figure 2 and Figure 8 shown, the unlocking member 12 of this embodiment further has a starting piece 123. One end of the starting piece 123 is connected to the snap connection piece 122, and the user pulls the two unlocking arms 121 by pulling the starting piece 123, which is convenient for operation.

The plurality of contact pads 1011 arranged in a column and the plurality of cable connection pads 1012 arranged in a column are arranged on opposite sides of the circuit board 101 in the first direction X. The plurality of cables 102 are connected to the plurality of cable connection pads 1012, and the wire end insulating body 103 covers the connection parts of the plurality of cables 102 and the plurality of cable connection pads 1012 and part of the circuit board 101. The side of the circuit board 101 having the plurality of contact pads 1011 is exposed from the wire end insulating body 103.

[0034] When the wire-end connector body 10 of this 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. One side of the circuit board 101 having a plurality of contact pads 1011 protrudes from the wire-end opening 1111 of the wire-end housing 11, and a plurality of cables 102 pass through from the side of the wire-end housing 11 away from the wire-end opening 1111. The wire-end insulating body 103 of this embodiment further has positioning grooves 1031 on opposite sides in the second direction Y, and the opposite side walls of the wire-end accommodating portion 111 of the wire-end housing 11 also have positioning protrusions 1112. 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, increasing the connection stability between the wire-end housing 11 and the wire-end insulating body 103. As Figure 4 shown, the circuit board 101 of this embodiment further has interference protrusions 1013 on opposite sides in the second direction Y. The interference protrusions 1013 interfere with the wire-end insulating body 103, increasing the connection stability between the circuit board 101 and the wire-end insulating body 103. The wire-end insulating body 103 and the wire-end housing 11 of this embodiment are both formed by injection molding.

[0035] As Figure 5 and Figure 6 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 in the slot 2011 along the third direction Z. The bottom surface of the board-end accommodating portion 211 of the board-end housing 21 has a notch 213 in the third direction Z. 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 exposes from the notch 213 to connect with an external circuit board.

[0036] In this embodiment, the two snap slots 212 of the board-end housing 21 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 slots 212 of the board-end housing 21 also respectively have extension support pieces 212c extending in the second direction. One side of the extension support piece 212c is connected to the other side of the side wall 212a and corresponds to the top surface 212b, that is, the extension support piece 212c and the top surface 212b are spaced apart in the third direction. The other side of the extension support piece 212c is in a suspended state. When the two snap protrusions 112 of the wire-end connector 1 are respectively arranged in the two snap slots 212, the extension support piece 212c supports the corresponding snap protrusion 112. There is a first included angle A1 between the extension support piece 212c and the side wall 212a. The angle of the first included angle A1 in this embodiment is 90 degrees, that is, the extension support piece 212c is orthogonal to the side wall 212a. Of course, the angle of the first included angle A1 can also be less than 90 degrees, reducing the distance between the extension support piece 212c and the top surface 212b. When the two snap protrusions 112 of the wire-end connector 1 are respectively arranged in the two snap slots 212, the movement of the snap protrusion 112 in the third direction Z is restricted by the extension support piece 212c and the top surface 212b.

[0037] The top surface of the board-end accommodating portion 211 of the board-end housing 21 also has two positioning pieces 214. The two positioning pieces 214 extend into the board-end accommodating portion 211 along the third direction Z. The top surface of the board-end insulating body 201 of the board-end connector body 20 also has two positioning grooves 2012 extending along the third direction Z. When the board-end connector body 20 is arranged in the board-end accommodating portion 211, the two positioning pieces 214 are respectively arranged in the two positioning grooves 2012 to position the board-end connector body 20 in the board-end accommodating portion 211. In this embodiment, there is a second included angle A2 between each of the two positioning pieces 214 and the top surface of the board-end accommodating portion 211 of the board-end housing 21. The angle of the second included 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 accommodating portion 211 of the board-end housing 21. In other embodiments, the angle of the second included 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 snap slots 212, thus effectively fixing the board-end connector body 20 in the board-end accommodating portion 211.

[0038] In summary, the present application provides a board - end connector and a connector assembly. The snap slot of the board - end connector is located on one side of the board - end connector body. The snap slot is provided for two snap protrusions and two unlocking arms of the wire - end connector. The two board - end snap portions act in the horizontal direction with the snap grooves of the two snap protrusions, the wire - end snap portions and the unlocking portions of the two unlocking arms. In this way, the thickness of the board - end connector in the vertical direction will not be increased, enabling the board - end connector to develop towards a thinner type.

[0039] The snap slot of the board - end connector in the present application further has an extended support piece, which can support the snap protrusion so that the snap protrusion can be stably arranged in the snap slot. The board - end accommodating portion of the board - end connector in the present application further has a positioning piece, and the board - end connector body further has a positioning groove. The positioning piece is arranged in the positioning groove so that the board - end connector body is stably arranged in the board - end accommodating portion.
