[ detailed description ] embodiments

For a fuller understanding of the objects, features and advantages of the present disclosure, reference should be made to the following detailed description taken in conjunction with the accompanying drawings.

In this disclosure, the use of "a" or "an" is used to describe elements, components and assemblies described herein. This is for convenience of illustration only and provides a general sense of the scope of the present disclosure. Thus, unless clearly indicated to the contrary, such description should be read to include one, at least one and the singular also includes the plural.

In this disclosure, the terms "comprising," "including," "having," "containing," or any other similar term are intended to cover non-exclusive inclusions. 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".

Fig. 1 is a schematic structural diagram of an easy-locking LVDS connector according to a first embodiment of the present disclosure. In fig. 1, an easy-to-lock LVDS connector 10 is provided for use with a flexible flat cable 2 having two laces, as shown in fig. 7. The two crevasses (such as a semi-closed notch or a closed hole) at the edge of the head end of the flexible flat cable 2 are mentioned in other patents by the inventor, and are not described herein, wherein the structure of the crevasses mainly provides a locking function.

Returning to fig. 1, the easy-to-lock LVDS connector 10 includes a rubber core 12 and a locking module 14.

Fig. 2 is a schematic diagram illustrating the structure of the rubber core shown in fig. 1. The rubber core 12 further forms an insertion opening 122, a containing space SP and

openings

124, 126. Here, the core 12 is additionally provided with a groove 128 in which an electrode terminal can be provided, and the insertion opening 122 is formed at the lower left side of the core 12. The core 12 forms an accommodating space SP to enable the flexible flat cable 2 to be set. The openings 124,126 are formed on the other side of the core rubber 12 corresponding to the insertion opening 122, i.e. the upper right side.

Referring back to fig. 1, the locking module 14 includes a first locking member 142 and a second locking member 144, and referring to fig. 3, a detailed diagram of the first locking member of fig. 1 is illustrated.

In fig. 3, the first locking member 142 further has a pressing block 1422, a resilient arm 1424, a locking block 1426, a fixing base 1428 and an extension arm 14210. Here, the pressing block 1422, the elastic arm 1424, the latching block 1426, the fixing base 1428 and the extension arm 14210 are illustrated as an S-shaped structure. The elastic arm 1242 and the locking block 1426 are simultaneously connected to the fixing seat 1428 and the extension arm 14210. The pressing block 1422 is connected to the elastic arm 1424 via an extension arm 14210.

The latching block 1426 further forms a slope 14262 and a retaining wall 14264. The inclined surface 14262 allows the flexible flat cable 2 to slide in, so that the crevasses of the flexible flat cable 2 act on the retaining wall 14264, which can stop the flexible flat cable 2 from withdrawing. The length of the fastening block 1426 is less than or equal to the length of the break, so that the break can be completely fastened to the fastening block 1426.

The pressing block 1422 is formed on the surface of the rubber core 12 and is disposed on the elastic arm 1424 in parallel to the latching block 1426, and when the elastic arm 1424, i.e., the pressing block 1422, is applied by an external force F, the external force F is transmitted through the extension arm 14210 and acts on the elastic arm 1424 and the latching block 1426, the elastic arm 1424 is deformed and compressed by the reaction force of the fixing seat 1428, because the elastic arm 1424 and the latching block 1426 are simultaneously connected to the fixing seat 1428 and the extension arm 14210, the compression of the elastic arm 1424 is also coupled to the latching block 1426, i.e., the latching block 1426 also changes position along with the deformation of the elastic arm 1424, so that the retaining wall 14264 moves downward and the inclined surface 14262 inclines by an angle until the retaining wall 14264 no longer stops the breach. And with reference to fig. 4, a cross-sectional view of the first fastener of fig. 1 in combination with a plastic core is illustrated.

The extension arm 14210 protrudes from the opening 124 by a first distance D1 to the edge of the rear side (or outer side) of the core 12. Since the extension arm 14210 is exposed and protrudes from the rear side (or outer side) of the rubber core 12 by the first distance D1, when an external force F is applied to the pressing block 1422, the pressing block 1422 and the elastic arm 1424 can generate a larger deformation amount through the extension arm 14210, and the pressing block 1422 does not perform a vertical motion only in the surface direction of the rubber core 12, which results in the situation that the pressing block 1422 impacts the surface of the rubber core 12.

In addition, since the structure of the second locking member 144 is the same as that of the first locking member 142, and the difference is only that a different position is provided, it is worth noting here that the first locking member 142 is exemplified. In fig. 1, the extension arm 14210 of the second locking member 144 protrudes from the opening 126 at the edge of the rear side of the glue core 12 by a second distance D2. Here, the first distance D1 is the same as the second distance D2.

Returning to fig. 1, the easy-to-lock LVDS connector 10 further includes a metal piece 16 disposed on the rubber core 12 to cover a surface of the rubber core 12, so as to shield electromagnetic interference, in addition to locking the rubber core 12 to the chassis or the substrate.

Fig. 5 is a schematic structural diagram of an easy-locking LVDS connector according to a second embodiment of the present invention. In fig. 5, an easy-to-lock LVDS connector 10' is provided that differs from the first embodiment in that the locking module 14 includes a connector 18 in addition to the rubber core 12.

The core 12 and the locking module 14 are substantially as described above and will not be described herein.

The connecting member 18 connects the pressing blocks 1422 of the first and

second locking members

142 and 144, and the elastic arms 1424 of the first and

second locking members

142 and 144 are deformed by pressing the connecting member 18 with an external force F, so that the snapping blocks 1426 of the first and

second locking members

142 and 144 can be simultaneously released. In this embodiment, the connecting member 18 can increase the contact area at the position where the external force F is applied, i.e. the position pointed by the contact portion 182, so that the external force F can be applied by a finger, for example.

Referring also to FIG. 6, a cross-sectional view of the first fastener of FIG. 5 in combination with a glue cartridge is illustrated. In fig. 6, the extension arm 14210 protrudes from the opening 124 by a first distance D1 to the edge of the rear side (or outer side) of the core 12. Since the extension arm 14210 is exposed and protrudes from the rear side (or outer side) of the rubber core 12 by the first distance D1, when an external force F is applied to the pressing block 1422, the pressing block 1422 and the elastic arm 1424 can generate a larger deformation amount through the extension arm 14210, and the pressing block 1422 does not perform a vertical motion only in the surface direction of the rubber core 12, which results in the situation that the pressing block 1422 impacts the surface of the rubber core 12.

Referring also to fig. 7, a cross-sectional view of the first locking member of fig. 1 is shown for locking the flexible flat cable. In fig. 7, after the flexible flat cable 2 is inserted into the insertion opening 122 and enters the accommodating space SP, the flexible flat cable 2 drives the locking module 14 to actuate to lock the two lacerations. When the flexible flat cable 2 is to be unlocked, the first locking member 142 and the second locking member 144 are driven independently by the external force F to unlock the locking module 14 from the second opening, so that the flexible flat cable 2 exits from the accommodating space SP through the insertion opening 122.

Although the embodiments of the present disclosure have been described above, it should be understood that various changes in the form, construction, features, methods and quantities described in the claims may be made by those skilled in the art without departing from the spirit and scope of the present disclosure, and therefore the scope of the present disclosure should not be limited by the claims appended hereto.
