Description

FIELD OF THE DISCLOSURE

The present disclosure relates to a cable connector and a combination thereof for connecting flexible flat cables (FFC) or flexible print circuits (FPC), and more particularly to a full-shielding cable connector and a combination thereof capable of improving electromagnetic interference (EMI) resistance.

BACKGROUND OF THE DISCLOSURE

Flexible flat cables (FFC) or flexible print circuits (FPC) are hereinafter both referred to as “cable” for the sake of brevity. Cables have been widely used in transmitting large quantities of data. In order to improve electromagnetic interference (EMI) resistance, a metal foil is usually adhered to an outer surface of a cable shielding layer. Since the shielding layer does not have a grounding circuit that is electrically contacted with the cable, an additional grounding process is required to ground the metal foil. Such additional grounding process is not only time-consuming, but also incurs high cost. Furthermore, this method does not ensure that the metal foil has a common ground with the shielding layer, a shell, and the grounding terminal of the cable.

In addition, another conventional method is to add the grounding terminal to the connector so that the grounding terminal is in contact with the shielding layer of the cable, and the entire cable is surrounded by the shielding layer. This method transfers costs to the manufacturer of the connector. In addition, in this method, only one side of the shielding layer is in contact with the grounding terminal of the connector, leading to a longer grounding passageway of the other side of the shielding layer on the cable.

Furthermore, in order to save space or use space effectively, when a conventional cable is electrically connected to a circuit board, the cable is parallel to the circuit board. Therefore, when a cable is installed to a cable connector on the circuit board, the cable is inserted into the cable connector along a direction parallel to the circuit board. This method of installing the cable by arranging the cable to the circuit board in an adjoining manner is not only difficult to implement, but also prone to cause a deviation of an insertion angle during installation and result in an erroneous installation.

Therefore, how an improved structural design can be provided to ensure the EMI resistance of the cable, so that the aforementioned shortcomings may be overcome, has become an important issue in this technical field.

SUMMARY OF THE DISCLOSURE

In one aspect, the present disclosure provides a full-shielding cable connector that is electrically connected to a circuit board. The full-shielding cable connector includes an insulated body, a plurality of terminals, a metal frame, a shielding conductive body, and a pull rod. The insulated body has a plurality of terminal slots formed along a first direction. The plurality of terminals is respectively received in the plurality of terminal slots, each of the plurality of terminals has a contact portion and a soldering portion, and the soldering portion is extended from the contact portion. The metal frame is fixed to the insulated body, and the metal frame has a plurality of pins so as to be electrically connected to the circuit board. The shielding conductive body is detachably assembled to the insulated body and is arranged above the metal frame, and the shielding conductive body has a cable entrance such that when a front end of a cable enters the shielding conductive body through the cable entrance, an upper shielding layer and a lower shielding layer of the cable are electrically connected to the shielding conductive body. The pull rod is rotatably connected to the shielding conductive body, and when the pull rod is rotated to a fastened position, the pull rod is fastened to the insulated body and so the shielding conductive body is fastened to the insulated body. When the shielding conductive body is assembled to the insulated body, the shielding conductive body is in physical contact with the metal frame.

In another aspect, the present disclosure provides a cable plug that is detachably assembled to a full-shielding cable connector that includes an insulated body and a metal frame, and the insulated body receives a plurality of terminals. The cable plug includes a shielding conductive body and a pull rod. The shielding conductive body is detachably assembled to the insulated body and arranged above the metal frame. The shielding conductive body has a front portion, a shielding top wall, and a pair of shielding side walls. The front portion, the shielding top wall, and the pair of shielding side walls have a cable receiving chamber formed therebetween. A cable entrance is formed on the front portion and contacts a bottom surface of the cable inserted therein, and the shielding top wall has a plurality of elastic arms formed thereon and extended inward into the cable receiving chamber such that the plurality of elastic arms contact a top surface of the cable. The pull rod is rotated with respect to the shielding conductive body. When the pull rod is rotated to a fastened position, the shielding conductive body is fastened to the insulated body. When the shielding conductive body is assembled to the insulated body, the front portion of the shielding conductive body is in physical contact with the metal frame.

In yet another aspect, the present disclosure provides a full-shielding cable connector that is electrically connected to a circuit board. The full-shielding cable connector includes a cable socket and a shielding conductive body.

When the shielding conductive body is assembled to the cable socket, the at least one guided portion, limited by the corresponding guiding installation portion, slides along a second direction for a predetermined distance. The second direction is perpendicular to the first direction.

Therefore, by the shielding conductive body and the metal frame being in physical contact with the shielding layers of the top surface and the bottom surface of the cable, the full-shielding cable connector of the present disclosure allows a good electrical connection between the cable and the grounding circuit of the circuit board, and achieves a full-shielding function that provides resistance against electromagnetic interference (EMI). The cable does not need to be additionally covered by extra metal foil, and the connector does not need additional grounding terminals to be in contact with the cable.

Specifically, the pull rod 60 is substantially in the shape of the letter U, and two ends of the pull rod 60 are pivotally connected to the pair of shielding side walls 52, respectively. The pull rod 60 may be rotated to a fastened position and be fastened to the cable socket, that is to say, the pull rod 60 may be rotated to a front end of the insulated body 10 and be fastened to the insulated body 10 and so the shielding conductive body 50 is fastened to the insulated body 10. The present embodiment further includes a pull tab 62 connected to the pull rod 60 for the pull rod 60 to be conveniently rotated by users.

Detailed processes of fixing the metal frame 30 and the insulated body 10 are as follows. Referring to FIG. 2 and FIG. 3, two opposing sides of the metal frame 30 are inserted and fixed to two opposing sides of the insulated body 10. Each of the pair of shoulder portions 12 of the insulated body 10 has two through slots 120 and 121 formed thereon along a second direction, and the second direction is perpendicular to the first direction. In other words, the second direction is a direction along the Z-axis. The two opposing sides of the metal frame 30 each have two fixing sheets 321 and 322 formed thereon.

Referring to FIG. 2 and FIG. 3, a top portion of the metal frame 30 is fastened to a top portion of the insulated body 10, and the horizontal top wall 31 of the metal frame 30 is fixedly assembled to the main portion 11 of the insulated body 10. Specifically, the main portion 11 of the insulated body 10 has a plurality of first fastening protrusions 113. The plurality of first fastening protrusions 113 protrude in the forward and backward directions from a top portion of the main portion 11. The horizontal top wall 31 of the metal frame 30 has a plurality of first fastening hooks 313. Specifically, a rear edge of the horizontal top wall 31 is bent downward to form the plurality of first fastening hooks 313 that are in a shape of a rectangular frame. In addition, a portion of the horizontal top wall 31 that is close to the front wall 33 is stamped downward to form the plurality of first fastening hooks 313 that are in a shape of a rectangular frame. The plurality of first fastening protrusions 113 of the insulated body 10 are correspondingly fastened to the plurality of first fastening hooks 313 of the metal frame 30.

In addition, a rear end of the metal frame 30 is fastened to a rear end of the insulated body 10, wherein the main portion 11 of the insulated body 10 has a plurality of second fastening protrusions 114. The plurality of second fastening protrusions 114 are positioned at a rear side of the terminal slots 110. Specifically, the plurality of second fastening protrusions 114 are formed at a rear edge of the main portion 11. The rear wall 34 of the metal frame 30 has a plurality of second fastening hooks 342, and the plurality of second fastening protrusions 114 of the insulated body 10 are respectively fastened to the plurality of second fastening hooks 342 of the metal frame 30. The second fastening hooks 342 of the present embodiment are also in a shape of a rectangular frame, but the present disclosure is not limited thereto. Referring to FIG. 2, each of the frame side walls 32 of the metal frame 30 further extends outward to form a rear positioning plate 323. The rear positioning plate 323 abuts against one of the shoulder portions 12 of the insulated body 10, but the present disclosure is not limited thereto. The main portion 11 may have a plurality of fastening protrusions, and the metal frame 30 may have a plurality of fastening hooks.

Detailed processes of assembling the shielding conductive body 50 and the insulated body 10 are as follows. Referring to FIG. 2, each of both sides in the front edges of the shielding top wall 51 has a positioning recessed portion 510 formed thereon. An upper block 125 protrudes upward from each of the shoulder portions 12 of the insulated body 10, and the upper block 125 passes through a top surface of the metal frame 30 when the metal frame 30 is fixed to the insulated body 10. When the shielding conductive body 50 is assembled to the insulated body 10, the upper block 125 is located in the positioning recessed portion 510.

Referring to FIG. 2, FIG. 3 and FIG. 6, a front end surface of the shoulder portion 12 of the insulated body 10 has a blocking member 126 formed thereon. When the shielding conductive body 50 is assembled to the insulated body 10, the pull rod 60 may be rotated to a fastened position so as to be fastened to the blocking member 126 of the shoulder portion 12. In the present embodiment, when the pull rod 60 is rotated to a fastened position, the pull rod 60 is fixedly fastened to the insulated body 10, thereby restricting the shielding conductive body 50 from moving backward along the direction of the X-axis. In other words, the shielding conductive body 50 and the cable 9 may be prevented from being detached from the cable socket (that is, the insulated body 10 and the metal frame 30). The quantity of the blocking member 126 may be at least one, but the present disclosure is not limited thereto. In addition, referring to FIG. 2 and FIG. 8, each of the shielding side walls has a side protruding block 526 protruding outward, and a side of the pull rod 60 is fixedly fastened to the side protruding block 526. This arrangement may strengthen a fastened state of the pull rod 60 to avoid an occurrence of accidental rotation of the pull rod 60.

Referring to FIG. 2, FIG. 6 and FIG. 10, for the purpose of restricting the shielding conductive body 50 from moving along the direction of the Z-axis, the outer side surface of the shoulder portions 12 of the insulated body 10 has a front limiting protrusion 122 and a rear limiting protrusion 124 formed thereon, and bottom edges of each of the shielding side wall 52 extend inward to form a front limiting tab 522 and a rear limiting tab 524. Referring to FIG. 8 and FIG. 9, when the shielding conductive body 50 is assembled to the insulated body 10, the front limiting tab 522 enters a bottom side of the front limiting protrusion 122, and the rear limiting tab 524 enters a bottom side of the rear limiting protrusion 124, thereby limiting the shielding conductive body 50 from moving along the direction of the Z-axis, but the present disclosure is not limited thereto. The quantity of the limiting protrusions of the shoulder portions 12 may be at least one, and quantities of the limiting tabs of the shielding conductive body 50 may be at least one. Each of the shielding side walls 52 abuts against one of the shoulder portions 12 of the insulated body 10 for limiting the shielding conductive body 50 from moving along the direction of the Y-axis. Therefore, when the pull rod is rotated to a fastened position, the shielding conductive body 50 is fastened to the insulated body 10.

Detailed processes of assembling the cable 9 to the cable socket of the present embodiment are as follows. Firstly, the cable 9 is assembled to the shielding conductive body 50. Referring to FIG. 3 and FIG. 5, the front end of the cable 9 is inserted into the shielding conductive body 50 via the cable entrance 530 of the shielding conductive body 50. Further, the front portion 53 of the shielding conductive body 50 extends inward to form a supporting wall 532. Referring to FIG. 11, a top surface of the supporting wall 532 is parallel to the first direction and substantially flush with a top surface of the front portion 53. The upper shielding layer 91a and the covering plate 94 is electrically connected with the elastic arms 512 of the shielding conductive body 50, and the lower shielding layer 91b is electrically connected to the supporting wall 532. Referring to FIG. 5, two ends of the supporting wall 532 respectively extend toward the shielding top wall 51 to form a side blocking portion 534 for blocking a pair of side recessed portions 92 of the cable 9 such that the cable 9 is fixed to the shielding conductive body 50. In other words, the side blocking portion 534 serves as a cable fixing portion, that can fix one cable inserted along the first direction. Furthermore, for enhancing the fixing effect, the cover plate 94 may extend to a rear side of the side recessed portion 92. The structural design of the present embodiment prevents the cable 9 from being detached outward from the shielding conductive body 50 when the cable 9 is assembled to the cable socket.

Referring to FIG. 6 and FIG. 7, the cable 9 and the shielding conductive body 50 are placed downward along a direction perpendicular to the circuit board P, that is, a direction of a negative Z-axis, on the insulated body 10 and the metal frame 30 (that is, the cable socket). During this process, the front limiting protrusion 122 and the rear limiting protrusion 124 constitute a guiding installation portion, and the front limiting tab 522 of the shielding conductive body 50 serves as a guided portion. In the process of placing the shielding conductive body 50 down on the cable socket, the guided portion is limited by the guiding installation portion to slide downward along the Z-axis for a predetermined distance until a predetermined height is reached.

Referring to FIG. 7 and FIG. 8, the shielding conductive body 50 and the cable 9 are moved in the forward direction (a direction along the X-axis referring to FIG. 7), so that the shielding conductive body 50 is fastened to a side of the insulated body 10.

Finally, referring to FIG. 8 and FIG. 9, the pull rod 60 is rotated forward, that is, rotated along a clockwise direction as shown in FIG. 8, to be fastened to the insulated body 10. The assembly process is therefore completed. At this time, the contact portions 21 of the terminals 20 are respectively in physical contact with the corresponding plurality of conductive bodies 95 of the cable 9 so as to be electrically connected thereto.

In this embodiment, to remove the cable 9 from the cable socket, as illustrated in FIG. 8, the pull rod 60 is rotated upward, that is, a counter-clockwise movement in FIG. 8, so as to disengage the pull rod 60 from the insulated body 10. The shielding conductive body 50 and the cable 9 are then pulled backward (along a negative X-axis direction as shown in FIG. 7) so as to disengage the shielding conductive body 50 from the insulated body 10. Finally, the shielding conductive body 50 and the cable 9 can be pulled upward.

Referring to FIG. 11, based on the aforementioned arrangements in the present disclosure, when the shielding conductive body 50 is assembled to the insulated body 10, the front portion 53 of the shielding conductive body 50 physically contacts the metal frame 30. Furthermore, a top end of the horizontal top wall 31 of the metal frame 30 is electrically connected to the shielding top wall 51 of the shielding conductive body 50. Preferably, a rear wall 34 of the metal frame 30 is also electrically connected to the supporting wall 532 of the shielding conductive body 50. Referring to FIG. 2 and FIG. 6, the horizontal top wall 31 of the metal frame 30 of the present embodiment has a plurality of conductive elastic arms 312 formed thereon. The plurality of conductive elastic arms 312 are in contact with the shielding top wall 51 of the shielding conductive body 50 so that the metal frame 30 is electrically connected to the shielding conductive body 50. The upper shielding layer 91a and the lower shielding layer 91b of the cable 9 are both in physical contact or electrically connected with the metal frame 30 through the shielding conductive body 50, and then are electrically connected to the grounding circuit (omitted in the figures) of the circuit board P through the metal frame 30. Furthermore, the front end of the cable 9 is surrounded by the shielding conductive body 50 and the metal frame 30 so as to form a good shielding effect, thereby achieving a good resistance against EMI.

In conclusion, one of the advantages of the present disclosure is that, in the full-shielding cable connector of the present disclosure, the cable does not require an additional grounding process to ground the covering metal foil, and the connector does not need additional grounding terminals to be in contact with the cable. By the shielding conductive body 50 and/or the metal frame 30 being in physical contact with the shielding layers of the top surface and the bottom surface of the cable 9, the present disclosure allows a good electrical connection between the cable and the grounding circuit of the circuit board, and achieves a full-shielding function that provides resistance against EMI.

Another advantage of the present disclosure is that, the cable is perpendicular to the direction of the Z-axis of the circuit board, and is inserted from top to bottom into the cable connector. In addition, a simple pull rod 60 is used to fix the cable to the cable connector. Therefore, an installation process of the cable is simplified and the correctness of the installation is ensured.

The foregoing description of the exemplary embodiments of the disclosure has been presented only for the purposes of illustration and description and is not intended to be exhaustive or to limit the disclosure to the precise forms disclosed. Many modifications and variations are possible in light of the above teaching.

The embodiments were chosen and described in order to explain the principles of the disclosure and their practical application so as to enable others skilled in the art to utilize the disclosure and various embodiments and with various modifications as are suited to the particular use contemplated. Alternative embodiments will become apparent to those skilled in the art to which the present disclosure pertains without departing from its spirit and scope.
