[0047] Please refer to Figure 1 , is a schematic diagram of the structure of the self-locking connector of the first embodiment of the present invention. Figure 1 In the figure, the self-locking connector 10 can connect a flat wire (not shown), the flat wire referred to here is the wire often used in the locking connector in the prior art, and will not be described here. Therefore, the flat wire in the prior art has a head end of the wire, and notches are formed on both sides of the head end.

[0048] The self-locking connector 10 includes a housing 12 , a pressing member 14 and two fixing members 16 .

[0049] For reference Figure 2a and 2b , which illustrates the present invention Figure 1 Schematic diagram of the shell structure. Figure 2a and 2bIn the embodiment, the housing 12 includes a first body 122, an inserting portion 124, a connecting portion 126 and two receiving portions 128. Figure 2a is a top view of the shell and Figure 2b is a front view of the shell.

[0050] In this embodiment, the first body 122 is a long rectangular body having a long side and a short side. Figure 2a The long side is in the horizontal direction and the short side is in the vertical direction.

[0051] exist Figure 2a In the embodiment, the connection portion 126 is formed on the outer side of the long side (ie, the aforementioned long side) of the first body 122 (ie, not on the same side as the accommodation space mentioned later).

[0052] The inserting portion 124 is formed in the middle of the first body 122 to form a receiving space, wherein the receiving space can receive the head end of the flat wire.

[0053] The two receiving portions 128 are respectively formed on the inner side (ie, located on one side of the receiving space) of the short side (ie, the aforementioned short side) of the first body 122 and communicate with the receiving space. The receiving portion 128 can receive the head end of the flat wire and the notches on both sides of the head end.

[0054] In this embodiment, reference is made to Figure 2b The connecting portion 126 further includes a plurality of first pivot blocks 1262 and a plurality of second pivot blocks 1264. The plurality of first pivot blocks 1262 and the plurality of second pivot blocks 1264 are equidistantly arranged. In another embodiment, the plurality of first pivot blocks 1262 and the plurality of second pivot blocks 1264 may also be unequally arranged. In other words, as long as the arrangement of the plurality of first pivot blocks 1262 and the plurality of second pivot blocks 1264 can be combined with the shaft body 148 mentioned later, it will be sufficient.

[0055] For reference Figure 3 , which illustrates the present invention Figure 1 Schematic diagram of the structure of the pressing part. Figure 3 In the embodiment, the pressing member 14 includes a second body 142 , a plate 144 and two first buckling blocks 146 .

[0056] Furthermore, the pressing member 14 further includes a plurality of shafts 148 and a plurality of spacer blocks 1410. In the present embodiment, the plurality of shafts 148 and the plurality of spacer blocks 1410 are arranged alternately, so that each shaft 148 is arranged corresponding to each first pivot block 1262 and each second pivot block 1264, and the plurality of spacer blocks 1410 are arranged between the plurality of first pivot blocks 1262 and the plurality of second pivot blocks 1264. After the pressing member 14 is combined with the connecting portion 126, each first pivot block 1262 and each second pivot block 1264 respectively limit each shaft 148 in the space formed by the plurality of first pivot blocks 1262 and the plurality of second pivot blocks 1264. In another embodiment, the configuration of the plurality of shafts 148 and the plurality of spacer blocks 1410 can be any structure as long as it can be combined with the plurality of first pivot blocks 1262 and the plurality of second pivot blocks 1264 mentioned above. In addition, in the present embodiment, each shaft body 148 is described as a cylinder and each spacer block 1410 is described as a rectangle. In other embodiments, the shape or form may not be limited.

[0057] exist Figure 3 In the embodiment, the pressing member 14 is combined with the connecting portion 126. The first buckling blocks 146 are respectively formed on both sides of the second body 142 and the plate body 144 is connected between the two first buckling blocks 146.

[0058] In this embodiment, both sides of the pressing member 14 are formed with inclined areas (i.e. Figure 3 In the embodiment of the present invention, the first buckle block 146 extends upwardly), after the pressing member 14 is engaged with the connecting portion 126, the pressing member 14 is limited in position on the housing 12 by the inclined surface area. For example, when the inclined surface of the inclined surface area contacts the housing 12, it is stopped by the housing 12, so that the pressing member 14 is limited and no longer moves.

[0059] For reference Figure 4 , which illustrates the present invention Figure 1 Schematic diagram of the structure of the fixing parts. Figure 4 In the embodiment, two fixing members 16 are respectively disposed in the accommodating portions 128 at two sides of the accommodating space, and each fixing member 16 includes a third body 162 , a protrusion 1612 and a pivoting groove 166 .

[0060] The material of the third body 162 can be metal to provide better elasticity and durability. The protrusion 1612 and the pivot groove 166 can be directly formed by the third body 162 in an integral molding manner or joined to the third body 162 by a connection manner. In the present embodiment, the protrusion 1612 is formed on the third body 162, and the position formed by the protrusion 1612 corresponds to the position of the notch of the head end. In the present embodiment, the protrusion 162 provides an arc surface and a stop surface. The arc surface allows the head end to slide into and pass over the protrusion 162, and the notch is stopped by the stop surface. When the protrusion 1612 is rotated by an external force, the stop surface can release the notch, so that the head end can slide out of the protrusion 162 along the arc surface; and, refer to Figure 5 , is a schematic diagram illustrating the combination of the pivot slot and the first buckle block of the present invention. Figure 5 In the embodiment, the pivot groove 166 is formed in the third body 162 to be able to engage with the first buckling block 146. When the pivot groove 166 is acted upon by an external force, the pivot groove 166 will drive the protrusion 1612 to rotate (or move). Here, the shape of the pivot groove 166 is described by taking a U-shaped groove as an example. In other embodiments, the shape is not limited. Figure 5 A larger size schematic diagram of the combination is also provided in Figure 6 Further explanation in Figure 5 A-A' cross-sectional view of the central connecting groove combined with the first buckling block.

[0061] In this embodiment, each fixing member 16 further includes a grounding electrode 164, a second buckling block 168 and a pin 1610. The grounding electrode 164 is connected to the third body 162 to provide an electrical connection wire. The second buckling block 168 protrudes from the third body 162 to buckle the third body 162 in the receiving portion 128. The pin 1610 is connected to the third body 162 for further connection (e.g., welding) to an external circuit board or external panel.

[0062] In the use scenario, the self-locking connector 10 provides a housing 12 with an accommodating space, and a connecting portion 126 with a first pivot block 1262 and a second pivot block 1264 is provided on the long side of the housing 12, and the connecting portion 126 is connected to the pressing member 14 with a shaft 148 and a spacer block 1410, so that the shaft 148 and the spacer block 1410 are arranged (or buckled) in the space formed by the first pivot block 1262 and the second pivot block 1264. After the connecting portion 126 is combined with the pressing member 14, the pressing member 14 can apply an external force to the plate 144 to allow the second body 142 to rotate, and the rotation range of the pressing member 14 is limited by the inclined surface area of ​​the two sides of the pressing member 14. After the two first buckling blocks 146 are respectively combined with the pivoting grooves 166 of the two fixing members 16 in the housing 12, the rotation of the pressing member 14 will operate the pivoting grooves 166 through the first buckling blocks 146, thereby causing the protrusion 1612 to be actuated, and the notch at the head end of the flat wire can be unlocked. In detail, after the flat wire is inserted into the accommodation space of the housing 12, the protrusions 1612 of the two fixing members 16 respectively lock the notches on both sides of the head end, so that the flat wire is limited in the accommodation space; conversely, when the plate 144 is subjected to external force (for example, applying external force to rotate or move the second body 142 toward the accommodation space), the second body 142 rotates to further deform the third body 162 and cause the protrusion 1612 to rotate, so that the protrusion 1612 is disengaged from the notch and the flat wire is released from being limited in the accommodation space.

[0063] Regarding the combination of the housing 12, the pressing member 14 and the fixing member 16, please refer to Figure 7 and Figure 8a-8c . Figure 7 is a schematic structural diagram of the self-locking connector of the present invention, and Figure 7 The section lines B-B', C-C' and D-D' are marked in Figure 8a illustrate Figure 7 The BB' cross-sectional view of the pivot groove 166 and the first buckling block 146; Figure 8b illustrate Figure 7 The CC' cross-sectional view of the shaft 148, the spacer block 1410 and the first pivot block 1262; and Figure 8c illustrate Figure 7 The DD′ cross-sectional view of the second body 142 and the second pivot block 1264 is shown in FIG.
