The elements of the drawings are not to scale and are provided solely for the purpose of illustrating the invention. Numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, it will be apparent to one of ordinary skill in the relevant art that the present invention may be practiced without one or more of the specific details, and therefore, such specific details should not be used to limit the invention.
Referring to fig. 1 and fig. 2, cross-sectional views of a connector 100 according to an embodiment of the invention are shown respectively when the connector is not connected and a butt object 10 is connected. In the present embodiment, the docking object 10 is a Flexible Printed Circuit (FPC), and the connector 100 is an electrical connector for electrically connecting and fixing the FPC. The connector 100 includes a housing 110, a conductive structure 120, and a cover plate 130. The mating object 10 includes electrical contacts 11 (e.g., gold fingers), and conductive structures 120 (e.g., terminals) disposed on the housing 110 and configured to contact the electrical contacts 11 to establish an electrical connection between the connector 100 and the mating object 10. In some embodiments, the conductive structure 120 comprises a metal or other suitable conductive material.
As mentioned above, the conductive structure 120 is bent to form a recess C configured to receive the docking object 10. The cover 130 is rotatably connected to the conducting structure 120, for example, the cover 130 can rotate between an open position shown in fig. 1 and a closed position shown in fig. 2. When the docking object 10 enters the recess C with the electrical contact 11 facing downward, the cover 130 can be rotated to the closed position, and at this time, the docking object 10 is fixed by the upper and lower clamping of the cover 130 and the conductive structure 120, and the electrical contact 11 of the docking object 10 contacts the conductive structure 120.
As shown in fig. 1 and 2, the conductive structure 120 includes an upper cantilever 128, a lower cantilever 129, a first contact 121, and a second contact 122. The housing 110 has a bottom surface 112, a lower suspension arm 129 is located between the upper suspension arm 128 and the bottom surface 112, and the length of the lower suspension arm 129 is greater than the length of the upper suspension arm 128. The first contact portion 121 and the second contact portion 122 are respectively located at the end of the upper cantilever 128 and the end of the lower cantilever 129, and the first contact portion 121 and the second contact portion 122 are configured to contact the electrical contact 11. The first contact portion 121 and the second contact portion 122 are located below the electrical contact 11, and a distance between the first contact portion 121 and the second contact portion 122 is smaller than a width of the electrical contact 11. In some embodiments, the first contact portion 121 and the second contact portion 122 are pin structures (pins), and tips of the pin structures point to the docking object 10.
As shown in fig. 1 and 2, in some embodiments, the housing 110 has a groove 113, and the conductive structure 120 is disposed in the groove 113. In some embodiments, the bottom surface 112 is the bottom surface of the groove 113. It should be noted that the drawings only depict the connector 100 including the single conductive structure 120 and the single groove 113, so as to more clearly show the structure of the connector 100, and the invention is not limited thereto. In some embodiments, the connector 100 may include a plurality of conductive structures 120 arranged in a row, and the housing 110 may include a plurality of grooves 113 to respectively receive one of the conductive structures 120.
As shown in fig. 1 and 2, in some embodiments, the height of the first contact portion 121 exceeds the groove 113, and when the cover plate 130 is rotated to the covering position and the abutting object 10 is pressed down, the first contact portion 121 penetrates into the electrical contact 11, so that the first contact portion 121 can be stably connected to the electrical contact 11. In some embodiments, the height of the second contact portion 122 is equal to or greater than the height of the groove 113, so that the first contact portion 121 and the second contact portion 122 can contact the electrical contact 11 simultaneously when the cover plate 130 is rotated to the covering position and the abutting object 10 is pressed down.
As shown in fig. 1 and 2, in some embodiments, the height H1 of the first contact portion 121 is greater than the height H2 of the second contact portion 122 (specifically, the height of the top end of the first contact portion 121 from the bottom surface 112 is greater than the height of the top end of the second contact portion 122 from the bottom surface 112). Designing the second contact portion 122 to be smaller in size can reduce the weight of the end of the longer lower cantilever 129.
As shown in fig. 1 and 2, the connector 100 further includes a fulcrum structure 140, and the fulcrum structure 140 is located between the lower cantilever 129 and the bottom surface 112 of the housing 110. In the present embodiment, the fulcrum structure 140 is disposed on the bottom surface 112 of the housing 110 and configured to abut against the lower suspension arm 129. The first contact portion 121 and the second contact portion 122 have a first vertical projection P1 and a second vertical projection P2 (vertical projection refers to a projection along the normal direction N of the bottom surface 112) on the bottom surface 112, respectively, and the third vertical projection P3 of the fulcrum structure 140 on the bottom surface 112 is located between the first vertical projection P1 and the second vertical projection P2. In other words, in the direction X in which the groove 113 extends, the fulcrum structure 140 is located between the first contact portion 121 and the second contact portion 122. In some embodiments, fulcrum structure 140 is a bump structure or a pointed structure. In some embodiments, fulcrum structure 140 is integrally formed with housing 110.
Referring to fig. 3, when the first contact portion 121 is covered by a foreign substance F (e.g., glue, particles) and cannot contact the electrical contact 11 of the mating object 10, the lower cantilever 129 can lift the second contact portion 122 by using the lever principle to make it contact or pierce the electrical contact 11, so as to maintain the electrical connection state between the connector 100 and the mating object 10.
As shown in fig. 3, specifically, the lower suspension arm 129 includes a first section 129a and a second section 129b, the first section 129a and the second section 129b are located on opposite sides of the fulcrum structure 140, wherein the first section 129a is located below the first contact portion 121, and the second section 129b is connected to the second contact portion 122. When the first contact portion 121 is covered by the foreign matter F and cannot contact the electrical contact 11 of the mating object 10, the foreign matter F inserted between the first contact portion 121 and the electrical contact 11 causes the first contact portion 121 to deflect downward and press down the first section 129a of the lower cantilever 129, and the lower cantilever 129 rotates with the fulcrum structure 140 as a fulcrum (the lower cantilever 129 may also be slightly bent), so that the second section 129b of the lower cantilever 129 rotates toward the mating object 10, and drives the second contact portion 122 to contact or pierce the electrical contact 11 upward.
As shown in FIG. 3, in some embodiments, lower cantilever 129 has a protruding structure 127, and protruding structure 127 is located below upper cantilever 128 and protrudes toward upper cantilever 128. With the above-mentioned structure configuration, the upper cantilever 128 can more easily press down the first section 129a of the cantilever 129 when the first contact portion 121 is covered by the foreign object F, and the sensitivity of the conductive structure 120 to the foreign object F is also increased, and the small-sized foreign object F causes the first contact portion 121 to be lowered by a small margin and can also lift up the second contact portion 122 to maintain the electrical connection state between the connector 100 and the docking object 10. In some embodiments, the protrusion 127 is located below the first contact 121.
As shown in fig. 3, the protrusion 127 contacts the upper cantilever 128 in this embodiment, but the disclosure is not limited thereto. In other embodiments, when the first contact portion 121 is not covered by the foreign material F, a gap is left between the protruding structure and the upper suspension arm 128 without direct contact.
Please refer to fig. 4 and 5. Fig. 4 is a cross-sectional view illustrating a connector 400 according to another embodiment of the present invention, and fig. 5 is a schematic view illustrating the connector 400 shown in fig. 4 when a second contact portion is covered with a foreign material F. In this embodiment, the second contact portion 422 of the conducting structure 420 is higher than the recess 113, when the second contact portion 422 is covered by the foreign object F and cannot contact the electrical contact 11 of the mating object 10, the foreign object F inserted between the second contact portion 422 and the electrical contact 11 causes the second contact portion 422 and the second section 129b of the lower cantilever 129 to deflect downward, and the lower cantilever 129 rotates with the fulcrum structure 140 as a fulcrum (the lower cantilever 129 may also be slightly bent), so that the first section 129a of the lower cantilever 129 rotates toward the mating object 10 and lifts the protrusion 127, thereby pushing the first contact portion 421 to contact or pierce the electrical contact 11 upward to maintain the electrical connection state between the connector 400 and the mating object 10.
Referring to fig. 6, a cross-sectional view of a connector 600 according to another embodiment of the invention is shown. The difference between this embodiment and the embodiment shown in fig. 2 is that the fulcrum structure 640 is disposed on the lower cantilever 129 of the conducting structure 620 and configured to abut against the bottom surface 112 of the housing 110. When the first contact portion 121 or the second contact portion 122 is covered by a foreign object F (not shown), the lower arm 129 can rotate around the fulcrum structure 640 (the lower arm 129 may also be slightly bent) by using the lever principle, so as to lift the first contact portion 121/the second contact portion 122 to make it contact or pierce the electrical contact 11 upward, thereby maintaining the electrical connection state between the connector 600 and the mating object 10.
In the present embodiment, the fulcrum structure 640 is disposed on the lower cantilever 129, and the lever structure can be realized by the conducting structure 620 alone without modifying the design of the housing, so as to ensure that when one of the first contact portion 121 and the second contact portion 122 is covered by the foreign object F (not shown), the other one can keep contact with the electrical contact 11 of the mating object 10.
As shown in fig. 6, in some embodiments, the fulcrum structure 640 is integrally formed with the lower cantilever 129. In some embodiments, the fulcrum structure 640 has a circular arc surface 640a, and the circular arc surface 640a faces the bottom surface 112, so that the fulcrum structure 640 can be prevented from penetrating into the housing 110 when the lower cantilever 129 is pressed down.
Referring to fig. 7, a cross-sectional view of a connector 700 according to another embodiment of the invention is shown. The present embodiment differs from the embodiment shown in fig. 2 in that the upper cantilever 128 of the conducting structure 720 has a protruding structure 727, and the protruding structure 727 is disposed facing the lower cantilever 129. The protrusion 727 functions like the protrusion 127 to make it easier for the upper cantilever 128 to depress the cantilever 129 when the first contact 121 is covered by a foreign object F (not shown), and also to increase the sensitivity of the conducting structure 720 to the foreign object F, and the small size of the foreign object F causes the first contact 121 to be lowered by a small amount to similarly lift the second contact 122 to secure the connection between the connector 700 and the docking object 10. In some embodiments, the protrusion structure 727 is located below the first contact 121. In some embodiments, the bump structure 727 contacts the lower cantilever 129.
In summary, the connector of the present invention is provided with a conductive structure having two cantilevers, wherein the ends of the two cantilevers are provided with contact portions for contacting with the mating object, and the connector further comprises a fulcrum structure, wherein when one of the contact portions is covered by the foreign object, the other contact portion can be lifted by using the lever principle to make the other contact portion contact with the mating object. With the above arrangement, the connector of the present invention can prevent contact failure caused by foreign matters.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
