The locking portion 1222 extends outward from the bent section 1221 along the first axis X (first axis line). The inclined section 1212 connects to the locking portion 123, and the protrusion 1233... Located in the receiving groove 111 and used to assemble the wire connector 2, the bent section 1221 is disposed at one end away from the horizontal section 1211 in the groove 1143. The bent section 1221 extends outward from the groove 1143 to cover one side 1141 of the locking block 114. The horizontal section 1211 covers the top surface 1142 of the locking block 114. The inclined section 1212 covers the other side 1141 of the locking block 114. The bent section 1221, the horizontal section 1211 and the inclined section 1212 surround each side 1141 and the top surface 1142 of the locking block 114.

[0025] Each elastic locking member 12' is respectively disposed in each groove 113 on both sides of the insulating base 11'.

The through part 133 is a notch formed on the side plate 132. The side arms 1232 of each elastic locking member 12' pass through each through part 133 and are connected to the pressing member 14'. The rod 141 of the pressing member 14' is inserted into the guide groove 1234 through the guide slot 12341, and the rod 141 is locked at the locking point 12342. The two limiting portions 142 of the pressing member 14' are locked on the outside of the two side arms 1232 to limit the range of movement of the rod 141 in the first axis X direction. The rod 141 is fixed to the locking point 12342. When the pressing member 14' is pressed along the second axis Y direction and the elastic locking members 12' are pushed at the same time, the spring arm 121 of each elastic locking member 12' will swing about the hook portion 122 as the axis along the second axis Y direction, so that the guide arm 1231 of each elastic locking member 12' is pushed and moves along the second axis Y direction, so that the protrusion 1233 disengages from the fastening portion 221.

[0031] Referring to Figure 12, which is a schematic diagram of the appearance of the elastic locking member 12'', in some embodiments, the elastic locking member 12'' of this embodiment differs from the elastic locking member 12' of the previous embodiment in that the end of the guide arm 1231 of the elastic locking member 12'' away from the protrusion 1233 does not include the side arm 1232 of the previous embodiment.

[0032] Referring to Figures 13 and 14, Figure 13 is a cross-sectional view of the section marked CC in Figure 9, showing the state in which the elastic locking member 12'' of the board connector 1 is engaged with the latching part 221 of the wire connector 2. When the connector 22 of the wire connector 2 is inserted into the receiving groove 111 through the insertion interface 112, each latching part 221 is engaged with each elastic locking member 12''. When the pressing member 14'' pushes the latching part 123 of each elastic locking member 12'', each latching part 221 disengages from the latching part 123 of each elastic locking member 12''. Specifically, since each groove 113 is connected to the receiving groove 111 of the insulating seat 11'', and each elastic locking member 12'' is disposed in the groove 113, when the wire end connector 2 is plugged into the board end connector 1, the connector 22 of the wire end connector 2 is inserted into the receiving groove 111 through the insertion interface 112, and each latching part 221 is engaged with the latching part 123 of each elastic locking member 12' in the receiving groove 111.

In some embodiments, the pressing arm 1431 includes a stop portion 14311, which is disposed on the side 1141 of the pressing arm 1431 and stops on the inner side of the cover plate 131. Specifically, the stop portion 14311 is disposed on the side 1141 of the pressing arm 1431, and each elastic locking member 12'' uses the elastic stop portion 14311 on the inner side of the cover plate 131 to keep the pressing member 14'' in contact with each elastic locking member 12''. When the pressing member 14'' pushes each elastic locking member 12'', the spring arm 121 swings along the second axis Y direction with the hook portion 122 as the axis. When the guide arm 1231 swings to the hollow portion 1161, the protrusion 1233 disengages from the fastening portion 221.

[0035] In summary, according to some embodiments, the elastic locking member is locked onto the insulating base, each elastic locking member is connected to the receiving groove through each groove, and each elastic locking member is connected to the latching part of the pressing member. When the pressing member is pressed and the elastic locking member is pushed, each latching part drives each spring arm to move, and each latching part moves away from each fastening part, thereby achieving the effect of releasing the connector of the wire end connector from the locking of the elastic locking member.
