When the line-end connector 100 is plugged into the board-end connector 200, since the second terminals 120 of the line-end connector 100 are arranged obliquely relative to the first terminals 220 of the board-end connector 200 (that is, the electrical connection between the second terminals 120 of the line-end connector 100 and the first terminals 220 of the board-end connector 200 has a certain oblique angle), the second terminals 120 of the line-end connector 100 and the first terminals 220 of the board-end connector 200 maintain the contact friction and the stress torque of the product terminals therebetween, and the terminal contact stroke of the product is small, thereby being able to reduce the overall height of the line-end connector 100, being suitable for the installation requirements of low space, and the contact electrical connection and the locking structure have good reliability.

[0042] In the present embodiment, one first locking tongue 141 is arranged on each side of the insulating body 110, and in other embodiments, the number of the first locking tongues 141 arranged on each side of the insulating body 110 can be multiple, which is determined according to actual needs.

[0043] As Figure 5As shown, each first locking tongue 141 comprises at least one locking portion 1412, which can be triangular in cross-sectional shape, and is capable of extruding both sides of the insulating housing 210 provided with the locking hole 230 to outwardly expand the insulating housing 210, so that the locking portion 1412 can be inserted into the locking hole 230 or separated from the locking hole 230.
