[0018] Further defined, in the above-mentioned high-current FPC connector, the cover plate is provided with a plurality of limit grooves which can be plugged with the signal terminals and the power terminals in a linear array along the length direction, and a buckle rod is fixed on the inner wall of the limit groove;

[0019] Wherein, a first embedded groove is provided at one end of the first driven plate of the signal terminal close to the first positioning seat, and the buckle rod can abut against the inner wall of the first embedded groove;

[0020] And / or a second driven plate of the power terminal is provided with a second embedding groove at one end close to the second positioning seat, and the buckle rod can abut against the inner wall of the second embedding groove;

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0042] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0043] The high-current FPC connector provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0044] like Figures 1 to 8 As shown, an embodiment of the present application provides a high-current FPC connector, including a rubber core 100 and a cover plate 200 detachably disposed on the rubber core 100 , and a plurality of signal terminals 300 are inserted in a linear array on the rubber core 100 .

[0045] Among them, two groups of power terminals 400 are also inserted on the rubber core 100, the two groups of power terminals 400 are symmetrical relative to the multiple signal terminals 300 and each group of power terminals 400 includes at least one power terminal 400, and the cover plate 200 can limit the displacement of the signal terminals 300 and the power terminals 400 relative to the rubber core 100 and the cover plate 200 in the buckled state.

[0046] It is understandable that when assembling the FPC connector, the cover 200 is first positioned on the rubber core 100, and then the signal terminal 300 and the power terminal 400 are inserted into the rubber core 100. When the cover 200 is fixedly installed on the rubber core 100, the cover 200 will interfere with and limit the signal terminal 300 and the power terminal 400. The signal terminal 300 and the power terminal 400 are deformed under the interference of the cover 200, and then retracted to achieve clamping and fixing of the flat cable 600.

[0047] In the embodiment of the present application, the above-mentioned high-current FPC connector is adopted to realize the circulation of high current through the power terminal 400, and the parallel structure of multiple signal terminals 300 is eliminated, which greatly simplifies the overall structure of the connector, occupies a small volume, and facilitates the miniaturization design of the connector.

[0048] In a preferred embodiment, Figure 3 As shown, each group of power terminals 400 includes two power terminals 400 .

[0049] In a preferred embodiment, the signal terminal 300 includes a first positioning seat, a first driven plate, and a first connecting frame for connecting the first positioning seat and the first driven plate.

[0050] After the signal terminal 300 is plugged into the rubber core 100 , the cover plate 200 can contact the first driven plate of the signal terminal 300 , thereby driving the first driven plate of the signal terminal 300 to deviate toward the first positioning seat to clamp the flat cable 600 .

[0051] In a preferred embodiment, the power terminal 400 includes a second positioning seat, two second connecting frames symmetrically and fixedly disposed on the second positioning seat, and second driven plates respectively fixedly disposed on one end of the two second connecting frames away from the second positioning seat.

[0052] After the power terminal 400 is plugged into the rubber core 100 , the cover plate 200 can contact the two second driven plates of the power terminal 400 , thereby driving the second driven plates of the power terminal 400 to move closer to the second positioning seat to clamp the flat cable 600 .

[0053] In a preferred embodiment, Figures 1 to 4 , Figure 6 As shown, the rubber core 100 is provided with a plurality of first slots 140 which can be plugged with the signal terminals 300 in a linear array along the length direction, and the first slots 140 are provided with a first positioning groove 110 which penetrates the corresponding side end surface of the rubber core 100 on the inner wall away from the cover plate 200 .

[0054] It can be understood that when the signal terminal 300 is inserted into the first slot 140, the first positioning seat of the signal terminal 300 is located at the corresponding position of the first positioning groove 110. The first positioning groove 110 can provide a clearance space for the first positioning seat of the signal terminal 300 when the cover plate 200 contacts the signal terminal 300, thereby improving the clamping adaptability to cables 600 of different specifications.

[0055] In a preferred embodiment, Figures 1 to 4 As shown, two groups of second slots 150 are symmetrically arranged on the rubber core 100 about the multiple signal terminals 300, which can be respectively plugged into the two groups of power terminals 400, and a second positioning groove 120 is arranged on the inner wall of the second slot 150 away from the cover plate 200 and penetrates the corresponding side end surface of the rubber core 100.

[0056] It can be understood that when the power terminal 400 is inserted into the second slot 150, the second positioning seat of the power terminal 400 is located at the corresponding position of the second positioning groove 120. The second positioning groove 120 can provide a clearance space for the second positioning seat of the power terminal 400 when the cover plate 200 contacts the power terminal 400, thereby improving the clamping adaptability to cables 600 of different specifications.

[0057] In a preferred embodiment, Figure 3 , Figure 6 As shown, a plurality of limiting grooves 210 capable of being plugged into the signal terminals 300 and the power terminals 400 are provided in a linear array along the length direction on the cover plate 200 .

[0058] A buckle rod 240 is fixed on the inner wall of the limiting groove 210 , and the buckle rod 240 can abut against the surface of the first driven plate of the signal terminal 300 close to the first positioning seat, or abut against the surface of the second driven plate of the power terminal 400 close to the second positioning seat.

[0059] The first driven plate of the signal terminal 300 has a first embedding groove for accommodating the buckle rod 240 on its surface near the first positioning seat, and the second driven plate of the power terminal 400 has a second embedding groove for accommodating the buckle rod 240 on its surface near the second positioning seat.

[0060] In the embodiment of the present application, the above-mentioned high-current FPC connector is adopted. When the cover plate 200 is buckled on the rubber core 100, the first driven plate of the signal terminal 300 and the second driven plate of the power terminal 400 are deformed under the resistance of the cover plate 200, and the buckle rod 240 can limit the first driven plate of the signal terminal 300 and the second driven plate of the power terminal 400. At the same time, through the cooperation of the first embedding groove on the signal terminal 300, the second embedding groove on the power terminal 400 and the buckle rod 240, the installation of the cover plate 200 on the rubber core 100 can be reinforced, thereby further improving the overall stability of the connector.

[0061] In a preferred embodiment, Figures 3 to 8 As shown, the two ends of the cover plate 200 are respectively fixed with limit stoppers 230 , and the rubber core 100 is provided with a buckle cavity 160 for accommodating the cover plate 200 .

[0062] The inner wall of the buckle cavity 160 is provided with an oblique abutting portion 190 capable of abutting against the limiting abutting member 230 , and the oblique abutting portion 190 is inclined toward a side close to the flat cable 600 .

[0063] When the cover plate 200 is installed, the cover plate 200 is first placed obliquely in the buckle cavity 160 of the rubber core 100, and then the signal terminal 300 and the power terminal 400 are installed, and the buckle rod 240 is located in the first embedding groove of the signal terminal 300 and the second embedding groove of the power terminal 400. At this time, the cover plate 200 is rotated about the buckle rod 240 to make it level with the rubber core 100, and the limit stopper 230 is in contact with the oblique stopper portion 190 in the vertical direction, that is, the displacement of the limit stopper 230 to the side away from the rubber core 100 is limited by the oblique setting of the oblique stopper portion 190, thereby realizing the buckling of the cover plate 200 on the rubber core 100.

[0064] It is understandable that the installation method of the cover 200 on the rubber core 100 is not limited to the above one, as long as the detachable connection of the cover 200 on the rubber core 100 and the clamping and abutment of the signal terminal 300 and the power terminal 400 can be achieved, which will not be elaborated here.

[0065] In a preferred embodiment, Figures 3 to 5 As shown, limiting protrusions 220 are fixedly provided at both ends of the cover plate 200 , and a clamping groove 170 is provided on the inner wall of the buckle cavity 160 , which is arranged opposite to the oblique abutment portion 190 and is used to accommodate the limiting protrusion 220 .

[0066] The end of the limiting protrusion 220 away from the cover plate 200 is provided with a guiding inclined portion capable of abutting against the rubber core 100 . When the cover plate 200 and the rubber core 100 are buckled together, the inner wall of the slot 170 close to the flat cable 600 can abut against the corresponding end of the limiting protrusion 220 .

[0067] In the embodiment of the present application, the above-mentioned high-current FPC connector is adopted. When the cover 200 is rotated and buckled with the rubber core 100, the limiting protrusion 220 can abut against the rubber core 100 through the guiding inclined portion and slide relatively. The inclined abutment portion 190 abuts against the limiting abutment 230 and causes the cover 200 to move relative to the rubber core 100 to the side away from the signal terminal 300 and the power terminal 400 until the limiting protrusion 220 moves into the slot 170. At this time, the inclined abutment portion 190 abuts against the limiting abutment 230 to limit the position, and the inner wall of the slot 170 abuts against the limiting protrusion 220 to limit the position, so that the cover 200 is not easy to flip up after closing, so that the cable 600 is not easy to loosen and the contact is more reliable.

[0068] In a preferred embodiment, Figures 1 to 3 , Figure 7 , Figure 8 As shown, the rubber core 100 is provided with mounting grooves 130 at both ends in the length direction, and the fixing members 500 are respectively embedded in the two mounting grooves 130 .

[0069] The fixing member 500 is welded on the printed circuit board and is used to fix the rubber core 100 .

[0070] In a preferred embodiment, Figure 7 , Figure 8 As shown, locking grooves 610 are respectively provided on the flat cable 600 at both ends of the rubber core 100 in the length direction, and a stopper 180 capable of plugging into the locking grooves 610 is fixedly provided on the rubber core 100 .

[0071] In the embodiment of the present application, the above-mentioned high-current FPC connector is used. When the flat cable 600 is installed on the connector, the plug-in limit of the stopper 180 and the lock groove 610 makes it difficult for the flat cable 600 to be pulled out, further improving the contact reliability of the signal terminal 300, the power terminal 400 and the flat cable 600.

[0072] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
