As shown in fig. 1-6, a cable connector assembly is provided for establishing electrical connections between multiple types of electronic components or devices according to an exemplary embodiment of the present disclosure.

In the illustrated exemplary embodiment, the cable connector assembly generally includes an electrical connector 100, a circuit board 200, and a cable 300. Illustratively, the electrical connector 100 will be described below and in the drawings as an example of a receptacle connector, but the disclosure is not limited thereto.

As shown, the electrical connector 100 includes a housing 110 and one or more first connection terminals 120 disposed at least partially within the housing 110. The housing 110 may be made of an insulating material such as plastic and defines a receptacle 101 for receiving a mating electrical connector (not shown). Each first connection terminal 120 has a connection end 121 and an opposite contact end 122, the contact ends 122 for making electrical contact with the terminals of the mating connector.

The circuit board 200 may be, for example, a PCB and has a front or first surface 201, an opposite back or second surface 202, and a side 203 therebetween, with the electrical connector 100 mounted on the first surface 201 such that the connection ends 121 of the first connection terminals 120 are positioned on the first surface 201. As an example, the connection end 121 of the first connection terminal 120 may be adhered to the first surface 201 or to the conductive trace 210 formed on the first surface 201 via conductive paste; alternatively, as shown in fig. 6, a pad or land 203 may be formed on the first surface 201 of the circuit board 200, and the connection end 121 of the first connection terminal 120 may be soldered to the pad or land 203. Illustratively, the first connection terminal may include a signal terminal, a power terminal, a ground terminal, and the like.

The cable 300 includes a cable body 310 and a second connection terminal 320 mounted at one end of the cable body 310 (e.g., electrically connected to a core wire or conductor of the cable), as described below, the second connection terminal 330 being electrically connected to the connection end 121 of the first connection terminal 120 of the electrical connector 100. The second connection terminal 320 may be directly connected to the connection end 121 of the first connection terminal 120, or as shown in fig. 4-6, the second connection terminal 320 may be connected to the connection end 121 of the first connection terminal 120 via a conductive trace 210 of the circuit board 200 (which is formed on the first surface 201 or in the circuit board 200, for example). The second connection terminals may also include corresponding signal terminals 321, power terminals, ground terminals 312, and the like, for example.

In an exemplary embodiment according to the present disclosure, a via or a through hole through which the cable 300 or the second connection terminal 320 thereof passes is not provided in the circuit board 200, but the second connection terminal 320 is positioned on the first surface 201 of the circuit board 200 and the cable body 310 is extended across the side surface 203 of the circuit board, i.e., the cable body 310 extends outwardly from the second connection terminal 320 on the first surface 201 and across the side surface 203 of the circuit board 200 between the first surface 201 and the second surface 202 outside the circuit board 200. In other words, in the cable connector assembly provided by the present disclosure, the via hole or through-hole in the circuit board is eliminated, the cable or the connection terminal thereof does not need to penetrate the circuit board in the thickness direction (Z direction in the drawing), but is electrically connected with the electrical connector by bypassing the side surface of the circuit board, which can ensure that better SI (signal integrity) is obtained, and the performance and performance consistency of the connector assembly are improved.

As an example, the second connection terminal 320 or the core wire of the cable 300, the conductor itself may be adhered to the first surface 201 via a conductive glue or to the conductive trace 210 formed on the first surface 201; alternatively, as shown in fig. 6, a pad or land 204 may be formed on the first surface 201 of the circuit board 200, and the second connection terminal 320 may be soldered to the pad or land 204.

In the illustrated embodiment, the cable body 310 extends or bends from the first surface 201 to the second surface 202 across the side 203 of the circuit board 200 on the outside of the circuit board 200, i.e., the cable body 310 has different portions, such as opposite ends, located on the first surface 201 and the second surface 202, respectively. In other embodiments, not shown, the cable body does not extend over the second surface or back of the circuit board after crossing the sides of the circuit board, but may extend beyond the circuit board, such as in the thickness direction (e.g., Z-direction in the figure) or in other different directions not in the plane of the second surface of the circuit board, as desired.

In the embodiment shown in fig. 3-5, the cable body 310 has a bend 311 that spans or bypasses the side 203 of the circuit board 200 or is positioned at least outside of the side 203. For example, the bent portion 311 may have a substantially U-shape or an L-shape.

Each cable may be electrically connected with one or more first connection terminals of the electrical connector. For example, each cable may include a pair of signal conductors and a ground conductor, which may be connected to corresponding second connection terminals (signal terminals and ground terminals), respectively. Depending on the arrangement and the actual requirements of the first connection terminals of the electrical connector, the cable connector assembly may include multiple cables on the same side or different sides of the electrical connector to avoid interference between adjacent terminals or terminal electrical connections.

The electrical connector may include at least one row of first connection terminals disposed within a housing thereof, and the cable connector assembly includes at least one row of cables, each row of cables being located on a same side of the electrical connector and being respectively electrically connected with a corresponding first connection terminal. For example, where the electrical connector includes a row of first connection terminals, the cable connector assembly may include a row of cables electrically connected to all of the first connection terminals in the row, or the cable connector assembly may include two or more rows of cables located on different sides of the electrical connector, each row of cables may be electrically connected to a portion of the first connection terminals in the row. Alternatively, the number of rows of the first connection terminals may be the same as the number of rows of the second connection terminals.

In the illustrated embodiment, the electrical connector 100 includes two rows of first connection terminals 120 spaced apart in a first direction (e.g., X-direction in the figures), each row of first connection terminals 120 being arranged spaced apart in a second direction (e.g., Y-direction in the figures), and the cable connector assembly includes two rows of cables 300 located on different or opposite sides of the electrical connector 100 in the first direction, each row of cables 300 being arranged spaced apart in the second direction and electrically connected to a corresponding row of first connection terminals 120. Illustratively, the dimensions of the circuit board 200 in a first direction (e.g., the X-direction in the figures) may be smaller than the dimensions of the circuit board 200 in a second direction (e.g., the Y-direction in the figures). For example, a first direction (e.g., X direction in the drawing) may be defined as a width direction of the circuit board, and a second direction (e.g., Y direction in the drawing) may be defined as a length direction of the circuit board. The two rows of cables are located on opposite sides of the electrical connector in the width direction of the circuit board, which results in a smaller length or distance that the cables extend over the first surface of the circuit board, reducing the area that the cables occupy on the first surface or front side of the circuit board.

In the embodiment shown in fig. 1-4, the circuit board 200 has a notch or gap in a first direction (e.g., the X-direction in the figures) to allow the cable 300 to span the sides of the circuit board 200 at the notch or gap, which further reduces the area occupied by the cable on the first surface or front side of the circuit board. The notch or indentation may have a dimension in a first direction (e.g., X-direction in the figures) that is smaller than a dimension in a second direction (e.g., Y-direction in the figures).

In some embodiments, as shown in fig. 1, 2 and 5, the cable connector assembly may further comprise a mounting base 400 adapted to be mounted on an electronic device, for example, the circuit board 200 being mounted on the mounting base 400 such that the cable body 320 and the second surface 202 and the side 203 of the circuit board 200 are at least partially covered by the mounting base 400, for example such that only the second connection terminals 320 or a portion thereof of the electrical connector 100 and the cable 300 are exposed. The mounting base 400 may firmly hold the cable 300 with respect to the circuit board 200.

Although embodiments of the present disclosure have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents. Furthermore, it should be noted that the terms "comprising," "including," "having," and the like, as used herein, do not exclude other elements or steps, unless otherwise specified. In addition, any element numbers of the claims should not be construed as limiting the scope of the disclosure.
