After the pressing element 14 is coupled to the connecting portion 126, each of the first pivoting blocks 1262 and each of the second pivoting blocks 1264 respectively limit each of the shaft bodies 148 in a space formed by the first pivoting blocks 1262 and the second pivoting blocks 1264. In another embodiment, the plurality of shafts 148 and the plurality of spacers 1410 may be configured in any manner as long as the aforementioned plurality of first pivot blocks 1262 and the aforementioned plurality of second pivot blocks 1264 can be combined. In addition, in the present embodiment, each shaft body 148 is illustrated as a cylinder and each spacer 1410 is illustrated as a rectangular body, and in other embodiments, the shape or shape may not be limited.

For example, when the inclined surface of the inclined surface region contacts the housing 12, the pressing member 14 is stopped by the housing 12 and is limited from moving.

Reference is also made to fig. 4, which is a schematic diagram illustrating the structure of the fixing member of fig. 1 according to the present invention. In fig. 4, two fixing members 16 are respectively disposed in the accommodating portion 128 at two sides of the accommodating space, and each fixing member 16 includes a third body 162, a protrusion 1612 and a pivot groove 166.

The third body 162 may be made of metal, so as to provide better elasticity and durability. The protrusion 1612 and the pivot groove 166 can be integrally formed with the third body 162 or can be connected to the third body 162. In this embodiment, the bump 1612 is formed on the third body 162, and the bump 1612 is formed at a position corresponding to the notch of the head end, in this embodiment, the bump 162 provides an arc-shaped surface and a stop surface, the arc-shaped surface enables the head end to slide into and over the bump 162, and the stop surface stops the notch, and when the bump 1612 rotates under an external force, the stop surface can release the stop notch, so that the head end can slide out of the bump 162 along the arc-shaped surface; and, referring to fig. 5, a combination diagram of the pivoting slot and the first fastening block of the present invention is shown. In fig. 5, the pivot slot 166 is formed on the third body 162 to be able to combine with the first fastening block 146, when the pivot slot 166 is acted by an external force, the pivot slot 166 will drive the protrusion 1612 to rotate (or be called to move), here, the shape of the pivot slot 166 is illustrated by a U-shaped slot body, and in other embodiments, the shape may not be limited. In addition, a larger-sized combination diagram is additionally provided in fig. 5, and a cross-sectional view A-A' of the central trough combination of the first fastening block in fig. 5 is further illustrated in fig. 6.

In the present embodiment, each fixing element 16 further includes a ground electrode 164, a second fastening block 168 and a pin 1610. A ground electrode 164 is connected to the third body 162 for electrically connecting the leads. The second fastening block 168 protrudes from the third body 162 for fastening the third body 162 to the accommodating portion 128. The pins 1610 are connected to the third body 162 for further connection (e.g., soldering) to an external circuit board or an external board.

In a use situation, the self-locking connector 10 provides a housing 12 having a receiving space, a connecting portion 126 having a first pivot block 1262 and a second pivot block 1264 is provided at a long side of the housing 12, and the connecting portion 126 is connected to a pressing member 14 having a shaft body 148 and a spacing block 1410, such that the shaft body 148 and the spacing block 1410 are disposed (or buckled) in the space formed by the first pivot block 1262 and the second pivot block 1264. After the connecting portion 126 is coupled to the pressing member 14, the pressing member 14 may be applied to the plate body 144 by an external force to rotate the second body 142, and the rotation range of the pressing member 14 is limited by the slope regions of the two sides of the pressing member 14. After the two first fastening blocks 146 are respectively combined and disposed in the pivot slots 166 of the two fixing elements 16 in the housing 12, the pressing element 14 rotates to operate the pivot slots 166 through the first fastening blocks 146, so that the bump 1612 is activated to perform an unlocking operation on the notch of the head end of the flat conductive wire. In detail, after the flat wire is inserted into the accommodating space of the housing 12, the two protrusions 1612 of the two fixing members 16 respectively lock the notches at the two sides of the head end, so that the flat wire is limited in the accommodating space; on the contrary, when the plate 144 is pressed by an external force (for example, the second body 142 is rotated or moved towards the accommodating space by the external force), the second body 142 is rotated to further deform the third body 162 and rotate the bump 1612, so that the bump 1612 is separated from the notch to release the limitation of the flat wire in the accommodating space.

The combination of the housing 12, the pressing member 14 and the fixing member 16 can be seen in fig. 7 and 8a-8 c.
