Description

Technical Field

[0001] The present application relates to an electrical connector cable assembly for transmitting electrical signals. More specifically, the present application relates to an electrical connector cable assembly for transmitting high-speed or high-frequency signals that can resolve electromagnetic interference. Background Art

[0002] Electrical connector cable assemblies are often installed in various modern electronic devices. Multiple electrical connector cable assemblies are connected in series within the electronic device to extend and transmit electrical signals. Current electrical connector cable assemblies can be roughly divided into the following three types of structures.

[0003] The first type of electrical connector cable assembly architecture consists of an FPC (Flexible Printed Circuit Board) or flexible circuit board connected to an electrical connector. This type of electrical connector cable assembly architecture is often limited by the stacking and wiring of the FPC, making it difficult to increase the signal transmission frequency. Generally, it can only transmit signals at frequencies below 10GHz. In addition, the signal loss of the FPC transmission is relatively large. Therefore, this type of electrical connector cable assembly architecture cannot provide long-distance transmission for high-frequency or high-speed signals.

[0004] The second type of electrical connector cable assembly consists of a flat cable, a circuit board, and an electrical connector. This type of electrical connector cable assembly primarily connects the flat cable and the electrical connector to the circuit board, with the circuit board electrically connecting the flat cable and the electrical connector to transmit signals. This type of electrical connector cable assembly typically incorporates additional retaining members to secure the circuit board, the flat cable, and the electrical connector attached to the circuit board, preventing the flat cable and the electrical connector from becoming detached. Generally, the retaining member is comprised of a metal or insulating housing that covers the junction between the flat cable, the electrical connector, and the circuit board. This results in a larger volume of the electrical connector cable assembly where the retaining member is added, requiring a larger amount of space.

[0005] The third type of electrical connector cable assembly architecture eliminates the circuit board and consists solely of a flat cable connected to terminals on an electrical connector. However, when transmitting high-speed or high-frequency signals, the flat cable connected to the electrical connector can cause electromagnetic interference (EMI). Therefore, in addition to adding a retaining member to prevent the flat cable and the electrical connector from detaching, this type of electrical connector cable assembly architecture typically requires an additional shielding member to provide shielding when the flat cable is connected to the electrical connector to transmit high-speed or high-frequency signals, thereby resolving the electromagnetic interference problem of signal transmission. Generally speaking, the shielding member is composed of a metal shell that can be covered at the point where the flat cable is connected to the electrical connector. This makes the electrical connector cable assembly larger where the shielding member is added, requiring a larger amount of space in the electronic device.

[0006] Therefore, how to prevent the flat cable from being detached from the electrical connector without adding additional retaining components, and how to solve the problem of electromagnetic interference without adding additional shielding components have become technical issues that the industry is eager to challenge and overcome.

Those familiar with the art can easily understand the other advantages and functions of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments. The details in this specification may also be modified and changed based on different viewpoints and applications without departing from the spirit of this application. In particular, the proportional relationships and relative positions of the various components in the drawings are for illustrative purposes only and do not represent the actual situation of the implementation of this application.

[0046] For the description of the embodiments disclosed in this application, please refer to Figures 1 to 28 .

[0047] exist Figures 1 to 15 In the illustrated embodiment, an electrical connector cable assembly 1 is disclosed. The electrical connector cable assembly 1 includes an electrical connector 11, a flat cable 12, a retaining shield carrier 13, and an insulating protective film 14. The electrical connector 11 has a signal terminal 111 and a ground terminal 112. The flat cable 12 has a signal line 121 and a ground line 122. The flat cable 12 can optionally be a coaxial cable with a three-layer cable structure without an outer insulating layer. Figures 5 and 6 as well as Figures 10 and 11 As shown, the flat cable 12 has an inner conductor layer 125 , an inner insulation layer 126 and an outer conductor layer 127 .

[0048] It should be noted that if the flat cable 12 is a coaxial cable without an outer insulating layer, the thickness of the flat cable 12 can be effectively reduced and can be used in a space with limited height.

[0049] In the above embodiment, the inner insulating layer 126 separates the inner conductor layer 125 from the outer conductor layer 127. The signal line 121 is located in the inner conductor layer 125 and can transmit high-frequency or high-speed signals. The ground line 122 is located in the outer conductor layer 127 and can transmit a shielded signal, such as a ground signal. The inner insulating layer 126 covers the inner conductor layer 125 to provide impedance matching for the signal transmission of the inner conductor layer 125. The outer conductor layer 127 covers the inner insulating layer 126 to provide shielding as a metal shielding layer to prevent the signal transmitted by the inner conductor layer 125 from being affected by electromagnetic interference (EMI), leakage loss, or forming a noise interference source for signal transmission, thereby enabling the flat cable 12 to provide long-distance transmission for high-frequency or high-speed signals. Optionally, the outer conductor layer 127 has a single-layer conductor structure or a multi-layer conductor structure composed of at least one of braided metal, wrapped metal, and wound metal.

[0050] However, the present invention is not limited to the above, and the flat cable 12 can be a metal cable or an electronic cable that can transmit signals. Figure 14 As shown, the flat cable 12 has a separate signal line 123 and a ground line 124 . Accordingly, the signal line 121 is located on the signal line 123 , and the ground line 122 is located on the ground line 124 .

[0051] like Figure 15 As shown, the retaining shield carrier 13 comprises a grounded conductive carrier plate 131, a grounded conductive back plate 132, and a cable passage 133.

[0053] like Figure 15As shown, the cable passage 133 is located between the grounded conductive carrier 131 and the grounded conductive backplane 132, and the flat cable 12 can be passed through the cable passage 133, so that the retaining shield carrier 13 can provide support for the flat cable 12 to prevent the flat cable 12 from being detached from the electrical connector cable assembly 1, and the signal line 121 can overlap the signal terminal 111, and the grounding line 122 can overlap the retaining shield carrier 13, so that the grounding terminal 112, the grounding line 122, the grounded conductive carrier 131 and the grounding conductive backplane 132 are electrically connected to form a grounding circuit, so that the retaining shield carrier 13 can provide EMI shielding for the overlap between the electrical connector 11 and the flat cable 12 through the grounding circuit. In this way, the electrical connector cable assembly 1 can be prevented from being subjected to electromagnetic interference at the joint between the electrical connector 11 and the flat cable 12 , which is beneficial for the application of the electrical connector cable assembly 1 in high-frequency or high-speed signal transmission.

[0054] It should be noted that in the above embodiment, the signal line 121 can be connected to the signal terminal 111 by soldering, hot pressing, laser welding, or resistance welding. Furthermore, the ground line 122 can be connected to the shield carrier 13 by soldering, hot pressing, laser welding, or resistance welding.

[0056] like Figure 14 As shown, the insulating protective film 14 is attached to the holding shield carrier 13 to provide insulation protection for the ground circuit to prevent the holding shield carrier 13 from electrical contact with other conductors during use and thus forming a short circuit. It should be noted that the insulating protective film 14 can be selected from adhesive film, hot adhesive film, and hot pressing film. Figure 15 As shown, the insulating protective film 14 is attached to the surfaces of the grounded conductive carrier 131 and the grounded conductive back plate 132 .

Furthermore, the hollow portion of the carrier hollow hole structure 1312 is aligned with the signal line bridge structure 153, preventing the signal line bridge structure 153 from overlapping (electrically connecting) the grounded conductive carrier 131.

[0062] like Figures 20 to 22As shown, the flat cable 12 can be passed through the cable passing channel 133, so that the retaining shield carrier 13 can provide retention for the flat cable 12, thereby preventing the flat cable 12 from being detached from the electrical connector cable assembly 1, and the signal line 121 can avoid the ground conductive carrier 131 through the hollow portion of the carrier hollow hole structure 1312 and overlap the signal line overlap structure 153, so that the signal line 121 can be electrically connected to the signal terminal 111 through the circuit board 15, and the ground line 122 can overlap the ground conductive carrier 131, so that the ground line 122 can be electrically connected to the ground terminal 112 through the ground conductive carrier 131 and the circuit board 15, thereby transmitting a shielding signal, such as a ground signal, to provide EMI shielding for the electrical connector 11. In this way, the electrical connector cable assembly 1 can be prevented from being subjected to electromagnetic interference at the joint between the electrical connector 11 and the flat cable 12 , which is beneficial for the application of the electrical connector cable assembly 1 in high-frequency or high-speed signal transmission.

[0063] Optionally, as Figures 20 to 21 As shown, the grounded conductive carrier 131 has a carrier cable guide structure 1311.

[0064] like Figures 25 to 26 As shown, the insulating protective film 14 is attached to the circuit board 15 to provide insulation protection for the ground line 122 to prevent the ground line 122 from electrically contacting other conductive objects and forming a short circuit. It should be noted that the insulating protective film 14 can be selected from adhesive film, thermal adhesive film, and hot pressing film.

[0065] It should be noted that the electrical connector cable assembly of the present application may also omit some components and is not limited to the above embodiments.
