Description

Technical Field

[0001] The present application relates to an electrical connector cable assembly for transmitting electrical signals, and more particularly, to an electrical connector cable assembly that can resolve electromagnetic interference and is used for transmitting high-speed or high-frequency signals. Background Art

[0002] Electrical connector cable assemblies are often installed in various modern electronic devices, so that multiple electrical connector cable assemblies are connected in series in the electronic device to extend the transmission of electrical signals. The current electrical connector cable assemblies can be roughly divided into the following three structures.

[0003] The first type of electrical connector cable assembly architecture is composed of an FPC soft row or a soft 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 soft row, making it difficult to increase the frequency of signal transmission. Generally, signals can only be transmitted at a frequency less than 10GHz, and the signal loss of the FPC soft row 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 structure is composed of a flat cable, a circuit board, and an electrical connector. The structure of this type of electrical connector cable assembly is mainly to allow the flat cable and the electrical connector to overlap the circuit board respectively, and transmit signals by electrically connecting the flat cable and the electrical connector via the circuit board. This type of electrical connector cable assembly structure usually adds additional retaining components to hold the circuit board and the flat cable and the electrical connector overlapped on the circuit board to prevent the flat cable and the electrical connector from detaching. Generally speaking, the retaining component is composed of a metal shell or an insulating shell that can be covered at the overlap between the flat cable and the electrical connector and the circuit board. This will make the volume of the electrical connector cable assembly where the retaining component is added larger and require a larger usage space.

[0005] The third type of electrical connector cable assembly structure excludes the circuit board and is composed of a flat cable connected to the terminal provided on the electrical connector. However, when the flat cable is connected to the electrical connector, there will be electromagnetic interference (EMI) problems. 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 structure usually requires additional shielding members to provide shielding when the flat cable is connected to the electrical connector to transmit high-speed or high-frequency signals, and solve the electromagnetic interference problem of signal transmission. Generally speaking, the shielding member is composed of a metal shell that can be covered at the place where the flat cable is connected to the electrical connector. In this way, the volume of the electrical connector cable assembly where the shielding member is added is larger, and it is necessary to occupy a larger use space in the electronic device.

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

In particular, the proportional relationship and relative position of each component in the accompanying drawings are only for exemplary purposes 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 embodiment shown, 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 shielding carrier 13, and an insulating protective film 14. The electrical connector 11 has a signal terminal 111 and a grounding terminal 112. The flat cable 12 has a signal circuit 121 and a grounding circuit 122. The flat cable 12 can be a coaxial cable with a three-layer cable structure without an outer insulating layer. Figures 5 and 6 as well as Figure 10 to Figure 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 shielding 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 as a metal shielding layer to provide shielding to prevent the signal transmitted by the inner conductor layer 125 from being subjected to electromagnetic interference (EMI), leakage loss or forming a noise interference source for signal transmission, so that the flat cable 12 can 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.
