For example, an element, structure, article, or apparatus that comprises a plurality of elements is not limited to only those elements but may include other elements not expressly listed or inherent to such element, structure, article, or apparatus. In addition, unless expressly stated to the contrary, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or".

Please refer to fig. 1, which is a schematic structural diagram of a connector according to an embodiment of the present disclosure. In fig. 1, the connector 10 can be used to connect a flexible flat cable (not shown) to a circuit board (not shown). Wherein, two sides of the front edge of the flexible flat cable are respectively provided with a notch.

The connector 10 includes a male connector 12, a female connector 14 and an electrical terminal 16.

Referring to fig. 2a and 2b together, fig. 2a is a schematic structural view illustrating a first housing of the male connector of fig. 1 and fig. 2b is a schematic structural view illustrating a second housing of the male connector of fig. 1. The male portion 12 includes a first housing 122 and a second housing 124. The first housing 122 and the second housing 124 may be integrally formed or separate components. The first housing 122 and the second housing 124 may be made of metal or nonmetal.

The first housing 122 and the second housing 124 form a first receiving space FSP for receiving the flexible flat cable.

A surface 1222 of the first housing 122 forms a locking member 1224 for locking the notch of the flexible flat cable. In the present embodiment, the locking member 1224 is illustrated as two elastic pieces, which are respectively referred to as a first elastic piece 12242 and a second elastic piece 12244. Taking the first elastic piece 12242 as an example, one end of the first elastic piece 12242 is connected to the surface 1222, and the free end of the first elastic piece 12242 extends from the surface 1222 toward the first receiving space FSP at an angle, that is, the free end of the first elastic piece 12242 extends obliquely toward the first receiving space FSP. Here, the free end of the first elastic piece 12242 and the free end of the second elastic piece 12244 extend in opposite directions, respectively. The first elastic piece 12242 and the second elastic piece 12244 are used for limiting the notch of the flexible flat cable. The length between the end of the free end of the first elastic piece 12242 and the end of the free end of the second elastic piece 12244 is not greater than the length of the gap.

The side of the first housing 122 forms a fastener 1226. Wherein, a protrusion 1228 protrudes from the inner edge of the fastener 1226, for example, the protrusion 1228 can be a triangle, and the bottom edge of the triangle is disposed on the inner edge surface of the fastener 1226 and contacts the fastening arm 142 mentioned later, so that the free end of the fastening arm 142 moves toward the first receiving space FSP.

Referring to fig. 3a and 3b together, fig. 3a is a top view illustrating the female socket 14 and the electrical terminal 16 of fig. 1 of the present invention, and fig. 3b is a bottom view illustrating the female socket 14 and the electrical terminal 16 of fig. 1 of the present invention. The female housing 14 forms a second receiving space SSP and a locking arm 142. The two sides of the second receiving space SSP are respectively provided with a buckling arm 142. Referring to fig. 4, which is a detailed structure diagram illustrating the latching arm 142 of fig. 3a and 3b, the latching arm 142 forms an opening 1422. One end 162 of the electrical terminal 16 is disposed in the second receiving space SSP, and the other end 164 protrudes out of the second receiving space SSP. Here, one end of the engaging arm 142 is fixed to the female housing 14.

Referring also to fig. 5, a partial unlocking schematic diagram illustrating the inventive combination of the male part 12 and the female part 14 of fig. 1 is shown. After the female housing 14 is locked to the male head 12, the engaging arm 142 can be moved from the first position P1 to the second position P2, for example, manually pulling the engaging arm 142 in the direction X.

Referring also to fig. 6, a partial locking schematic diagram illustrating the inventive combination of the male part 12 of fig. 1 with the female part 14 is shown. The projection 1228 of the male portion 12 abuts against the engaging arm 142, such that the engaging arm 142 moves from the first position P1 to the second position P2 until the projection 1228 is inserted into (or dropped into) the opening 1422, and the engaging arm 142 returns from the second position P2 to the first position P1 (i.e. moves in the-X direction), such that the female portion 14 is locked to the male portion 12.
