Detailed Description
The following examples are presented to illustrate the utility model and are not intended to limit the utility model to any particular environment, application, or particular manner in which it may be practiced. Accordingly, the description of the embodiments is merely for the purpose of illustrating the utility model and is not intended to limit the utility model. It should be noted that, in the following embodiments and the accompanying drawings, some components not directly related to the present utility model are omitted and not shown, and the dimensional relationships among the components in the drawings are only for easy understanding, and are not intended to limit the actual scale.
Please refer to fig. 1 to 5. Fig. 1 and 2 are schematic perspective views of the connector 1 according to the present utility model in horizontal and vertical states, respectively. Fig. 3 and 4 are exploded perspective views of the connector 1 of the present utility model. Fig. 5 is a top view of the connector 1 of the present utility model. The connector 1 is disposed on a printed circuit board 2 and is plugged with a flexible flat cable 3. The connector 1 comprises a housing 11, a locking structure 12, and a supporting frame 13, wherein the locking structure 12 and the supporting frame 13 are disposed in the housing 11, and a part of the locking structure 12 and the supporting frame 13 are exposed out of the housing 11. The flexible flat cable 3 further has a notch 31 at two side edges for engaging with the connector 1.
As shown in fig. 8, the housing 11 includes a receiving groove 111 and a plurality of terminals 112, the receiving groove 111 is used for connecting the flexible flat cable 3, the receiving groove 111 has a reference surface 1111, and the plurality of terminals 112 extend and are disposed in the receiving groove 111 (see fig. 4) to electrically connect the printed circuit board 2 and the flexible flat cable 3. In one embodiment, the pitch between any two adjacent terminals may be 0.5 millimeter (mm), and the number of terminals corresponding to the flexible flat cable 3 may be 30, so as to form a small-sized connector with a contact terminal length of 15 mm.
Referring to fig. 7, the engaging structure 12 includes a pressing portion 121, a pivoting portion 122, and a fastening portion 123. The pressing portion 121 and the fastening portion 123 are disposed opposite to each other with the pivoting portion 122 as a center, the pressing portion 121 is disposed adjacent to the pivoting portion 122, the fastening portion 123 can be disposed at opposite ends of the pivoting portion 122, and the pivoting portion 122 can be pivotally disposed on the housing 11, so that the locking structure 12 can be switched between a locking position and an unlocking position. In one embodiment, the engaging structure 12 is an integrally formed plastic structure, which is not limited herein.
In an embodiment, as shown in fig. 8, the locking portion 123 has a guiding surface 1231 and a stopping surface 1232, which are respectively formed on two sides of the locking portion 123, the guiding surface 1231 has an inclined plane segment 12311 and an arc surface segment 12312 in sequence, when the flexible flat cable 3 is inserted into the accommodating groove 111 along the reference surface 1111, the flexible flat cable 3 pushes against the guiding surface 1231, and pushes against the inclined plane segment 12311 and the arc surface segment 12312 in sequence, so that the locking portion 123 is retracted from the accommodating groove 111 and the locking structure 12 rotates to the unlocking position. The inclined plane segment 12311 can save more effort when the flexible flat cable 3 pushes against the fastening portion 123, so that the flexible flat cable 3 is easy to be inserted into the accommodating groove 111. However, the other side of the locking portion 123 opposite to the guiding surface 1231 is a stop surface 1232, and when the flexible flat cable 3 is disposed in the accommodating groove 111 and the locking structure 12 rotates to the locking position, the stop surface 1232 limits the flexible flat cable 3 from being separated from the accommodating groove 111. Preferably, the stop surface 1232 is a non-linear surface and is non-perpendicular to the reference surface 1111. When the flexible flat cable 3 is in the accommodating groove 111 and the locking structure 12 is located at the locking position, the stop surface 1232 partially contacts the flexible flat cable 3 when the force is pulled from inside to outside, so that the pushing stress is concentrated at the front end of the fastening portion 123, which is less likely to cause damage to the fastening portion 123.
In addition, as shown in fig. 8, an included angle θ is defined between the inclined plane segment 12311 and the reference plane 1111, and the included angle θ is between 30 degrees and 45 degrees, and may be preferably 36 degrees. The design can make the flexible flat cable 3 push against the buckling part 123 more easily, further make the locking structure 12 pivot to the unlocking position, and can maintain the strength of the buckling part 123.
In one embodiment, referring to fig. 6 and 7, the supporting frame 13 is disposed on the printed circuit board 2 and holds the housing 11. The supporting frame 13 includes a spring 131 and a stop 132, wherein the spring 131 abuts against the pressing portion 121, so that the locking structure 12 tends to return to the locking position. In addition, the stop block 132 has a limiting function, and can fix the fastening portion 123 in the housing 11 and maintain the fastening structure 12 in the locking position. It should be noted that, the supporting frame 13 is disposed in the housing 11 and has a supporting force for supporting the engaging structure 12 in the housing 11, in this embodiment, the supporting frame 13 may be made of a metal sheet, and considering the supporting stability and the pivoting effect between the engaging structure 12 and the supporting frame 13, the number of the supporting frame 13, the elastic sheet 131 and the stop block 132 is taken as two as an example, and the number of the corresponding supporting fastening portions 123 is also taken as two as an example, which can be adjusted according to practical requirements and is not limited herein.
The following describes the movement relationship between the connector 1 and the flexible flat cable 3 in detail. As shown in fig. 9 and 10, when an external force is applied to the pressing portion 121 of the locking structure 12, the locking structure 12 rotates about the pivot portion 122 to the unlocking position, so that the locking portion 123 is retracted from the accommodating groove 111, and the flexible flat cable 3 inserted in the connector 1 can be retracted from the accommodating groove 111. When the external force is removed, the elastic piece 131 rotates the engaging structure 12 to the locking position, the fastening portion 123 extends to the accommodating groove 111, and at this time, the fastening portion 123 extends to at least two thirds of the accommodating groove 111 (refer to fig. 9). In another implementation state, the flexible flat cable 3 is inserted into the accommodating groove 111, and when the flexible flat cable 3 is inserted into the accommodating groove 111 and pushes against the locking portion 123 (in this case, it can be considered that an external force is applied to the locking portion 123), the locking structure 12 is similarly rotated about the pivot portion 122 to the unlocking position, so that the locking portion 123 is retracted from the accommodating groove 111. When the flexible flat cable 3 is inserted into the accommodating groove 111 to be positioned (in this case, it can be regarded as external force removal), the elastic sheet 131 rotates the locking structure 12 to return to the locking position, and the fastening portion 123 extends to the accommodating groove 111 and penetrates through the notch 31 (see fig. 10).
In summary, the connector of the present utility model is designed by combining the housing, the locking structure and the supporting frame, and by the design that the locking structure is integrally made of plastic, wherein the plastic locking portion has the same strength as the metal locking component in the prior art, so that the flexible flat cable can be inserted on the connector and can be easily changed between the locking state and the unlocking state, and further the flexible flat cable can be automatically assembled on the connector, thereby achieving the effects of saving the manufacturing cost and reducing the assembly time.
The above examples are only for illustrating the novel embodiments and illustrating the technical features of the present utility model, and are not intended to limit the scope of the present utility model. Any modifications or equivalent arrangements which may be readily apparent to those skilled in the art are intended to be included within the scope of the present utility model, which is to be accorded the full scope of the appended claims.
