The side wall reinforcing sheet includes a side top plate 65 at least partially covering the top surface of the side portion 52, and a side plate 66 extending from the lateral outer side of the side top plate 65 in a downward bent manner, and the side plate 66 at least partially covers the outer wall surface of the side portion 52. The side roof panels 65 are connected to both lateral ends of the end roof panel 61 so that the side reinforcing sheets are formed integrally with the end reinforcing sheets. The side roof portion 65 is located above the elastic arm 64, and thus serves to protect the elastic arm 64. The side plate 66 does not protrude beyond the outer wall surface of the side portion 52, and the side plate 66 does not increase the overall volume of the female connector 200 while improving the strength of the side portion 52 of the female connector body 50. The female seat body 50 is provided with a receiving groove 56 positioned on the outer wall surface of the side portion 52, and the side portion side plate portion 66 is received in the receiving groove 56, so that stability of fixing the female seat protection bracket 60 to the female seat body 50 is enhanced.

When the male connector 100 is mated with the female connector 200, the male body 10 is received in the female slot 54 of the female body 50, and the latching portion 44 of the locking lever 41 is pushed by the female protection bracket 60 to move laterally inward until the latching portion 44 is latched in the latching slot 621 of the female protection bracket 60 when the male connector 100 is completely plugged into the female connector 200, so that the male connector 100 is difficult to separate from the female connector 200 without a special unlocking tool.

As shown in fig. 9A to 9B, two through holes 505 penetrating the circuit board 500 vertically are provided at two sides of the circuit board 500 in the longitudinal direction, the legs 431 of the self-locking member 40 extend into the through holes 505, the through holes 505 are near the longitudinal and transverse edges of the circuit board 500, the through holes 505 are provided with a first inner sidewall 501 and a second inner sidewall 502 opposite to each other in the longitudinal direction, the first inner sidewall 501 is located at the longitudinal outer side of the second inner sidewall 502 and is longitudinally spaced apart from the legs 431 respectively, so that the legs 431 are convenient for swinging longitudinally.

Referring to fig. 7A to 8B, a board-to-board connector unlocking jig 300 is disclosed in the preferred embodiment of the present utility model, which can be used to separate the male connector 100 from the female connector 200. The board-to-board connector unlocking jig 300 is an integral structure including a base 301, a pair of body arms 302 extending downward from both longitudinal sides of the base 301, and a pulling arm 303 extending downward from a lateral outside of the base 301.

Each body arm 302 is provided with an unlocking support arm 3021, a pressing support arm 3022, and a connecting portion 3023 for connecting the unlocking support arm 3021 and the upper end of the pressing support arm 3022, wherein the unlocking support arm 3021 and the pressing support arm 3022 are arranged at the lower end of the body arm 302, and the unlocking support arm 3021 is located at the inner side of the pressing support arm 3022 in the longitudinal direction and is longitudinally spaced apart and can be staggered or aligned with each other. The lateral width of the unlocking support arm 3021 is smaller than that of the pressing support arm 3022, the lower ends of the unlocking support arm 3021 and the unlocking support arm are located at the same height, guide surfaces 30210 and 30220 facing the same longitudinal inner side are respectively arranged, and the guide surfaces 30210 and 30220 are cambered surfaces or inclined surfaces. The connection portion 3023 is horizontally arranged.

The lower end of the pulling arm 303 is provided with a hook portion 3031, the longitudinal width of the hook portion 3031 is larger than the transverse width of the pressing support arm 3022, the hook portion 3031 is positioned at the transverse inner side of the pulling arm 303, and the hook portion 3031 is provided with a guide surface 30310 facing downwards and transversely inwards. In addition, the hook 3031 and the unlocking arm 3021 are offset from each other in the longitudinal and transverse directions.

As shown in fig. 9A to fig. 10B, when the male connector 100 and the female connector 200 need to be separated, first, the board-to-board connector unlocking jig 300 is moved downward as a whole, and the two unlocking arms 3021 are gradually inserted into the through hole 505 of the circuit board 500 until being partially inserted into the slot hole 15, so as to release the locking of the self-locking member 40 to the female connector 200; the pressing support arm 3022 presses the outer edge of the circuit board 500 in the longitudinal direction; the lower end of the pulling arm 303 passes down over the laterally outer edge of the circuit board 500, with the hook 3031 being located below the circuit board 500. When the board-to-board connector unlocking jig 300 is inserted to the bottom, the unlocking jig 300 is lifted upwards, the hook 3031 drives the lateral outer edge of the circuit board 500 to move upwards, and the circuit board 500 moves the male connector 100 to move upwards synchronously, so that the male connector 100 and the female connector 200 are separated.

During the process of inserting the unlocking support arm 3021 into the through hole 505 of the circuit board 500, the guide surface 30210 of the unlocking support arm 3021 abuts against the leg 431 of the self-locking member 40 to move towards the second inner side wall 502, so that the locking lever 41 overcomes the elastic force of the elastic piece 42, drives the buckling part 44 to move towards the longitudinal inner side and withdraw from the buckling groove 621, abuts against the guide surface 30220 of the support arm 3022 to contact with the longitudinal outer side edge of the circuit board 500, guides the abutting support arm 3022 to move downwards, and guides the guide surface 30310 of the hook 3031 to contact with the transverse outer side edge of the circuit board 500, so that the guide hook 3031 moves downwards to below the circuit board 500.

The board-to-board connector unlocking jig 300 is simple in structure, and only needs to move the board-to-board connector unlocking jig 300 downwards once, so that two unlocking support arms 3021 are synchronously inserted into corresponding through holes 505 of a circuit board 500, and the locking of the two longitudinal ends of the male connector 100 and the female connector 200 is released; when the board-to-board connector unlocking jig 300 moves downwards, the board-to-board connector unlocking jig 300 is lifted up only once, so that the whole male connector 100 and the female connector 200 are separated, and the male connector 100 and the female connector 200 are separated easily, simply, conveniently and reliably.

In summary, the above description is only a preferred embodiment of the present utility model, and should not be taken as limiting the scope of the utility model, i.e. all simple and equivalent changes and modifications that are defined by the claims and the specification shall fall within the scope of the utility model.
