[0029] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings. In this specification, identical or similar components are indicated by identical or similar reference numerals. The following description of various embodiments of this disclosure with reference to the accompanying drawings is intended to illustrate the overall concept of this disclosure and should not be construed as a limitation thereof.

[0030] Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a thorough understanding of embodiments of the present disclosure. However, it will be apparent that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and apparatuses are illustrated to simplify the figures.

[0031] According to the inventive concept of this disclosure, a multi-channel coaxial connector is provided, comprising: an insulating body having a plurality of sockets; and a plurality of connecting terminals, each connecting terminal being adapted to be inserted into a corresponding socket and configured for connecting a coaxial cable, each connecting terminal having an inner conductor and an outer conductor arranged coaxially, each socket forming a first locking groove and a second locking groove, at least two adjacent sockets having first locking grooves communicating with each other, and an conductive positioning structure being provided on the outer peripheral surface of the outer conductor of each connecting terminal, the positioning structure being configured to engage with one of the first locking grooves and the second locking groove of the corresponding socket to connect the connecting terminal. Positioned in the corresponding sockets, the plurality of connecting terminals are adapted to be inserted into the plurality of sockets respectively in one of a first configuration or a second configuration. In the first configuration, the positioning structure of each connecting terminal engages with the first locking groove of the corresponding socket, and the positioning structures of the connecting terminals inserted into at least two adjacent sockets are in contact with each other, such that the outer conductors of the connecting terminals inserted into at least two adjacent sockets are electrically connected to each other. In the second configuration, the positioning structure of each connecting terminal engages with the second locking groove of the corresponding socket, and the positioning structures of the plurality of connecting terminals are spaced apart from each other, such that the outer conductors of the plurality of connecting terminals are electrically isolated from each other.

[0032] According to another inventive concept of this disclosure, a multi-channel coaxial connector is also provided, comprising: an insulating body having a plurality of sockets, each socket having a first locking groove, wherein the first locking grooves of at least two adjacent sockets are interconnected; and a plurality of connecting terminals, each connecting terminal being adapted to be inserted into a corresponding socket and having an inner conductor and an outer conductor arranged coaxially, wherein a conductive positioning structure is provided on the outer peripheral surface of the outer conductor of each connecting terminal, the positioning structure being configured to engage with the first locking groove of the corresponding socket to position the connecting terminal in the corresponding socket; wherein the positioning structures of the connecting terminals in the at least two adjacent sockets are in contact with each other, such that the outer conductors of the connecting terminals inserted into the at least two adjacent sockets are electrically connected to each other.

[0033] Figure 1 The illustration schematically depicts a cable assembly according to an exemplary embodiment of the present disclosure, comprising a plurality of cables 1 (coaxial cables) arranged side-by-side and a multi-channel coaxial connector 100 connecting the cables 1. The two ends of the cables 1 can be respectively connected to the multi-channel coaxial connector 100, which can be electrically connected to an electrical device or a component thereof, such as to a mating connector on the electrical device (e.g., see...). Figure 7 The connector 200 shown provides an electrical connection, enabling connection between electrical devices via a cable assembly to achieve electrical / signal transmission or communication. As an example, the multi-channel coaxial connector 100 may be a radio frequency (RF) coaxial connector.

[0034] like Figure 1-3 As shown, the multi-channel coaxial connector 100 according to an exemplary embodiment of the present disclosure includes an insulating body 110 and a plurality of connection terminals 120. A plurality of sockets 111 are formed or provided in the insulating body 110. The sockets 111 are through holes that penetrate the insulating body 110 in the thickness direction (Z direction in the figure). Each connection terminal 120 is adapted to be inserted into a corresponding socket 111 to connect a cable 1, such as an RF coaxial cable, at one end.

[0035] like Figures 1 to 5B As shown, the connecting terminal 120 can be a coaxial terminal, including an inner conductor 121 and an outer conductor 122 arranged coaxially. The inner conductor 121 is electrically connected to the core wire of the cable 1, while the outer conductor 122 is electrically connected to the shielding layer or ground of the cable 1. Exemplarily, the outer conductor 122 can be a cylindrical structure positioned around the central inner conductor 121. Typically, the cylindrical outer conductor is not a completely closed shape, but rather a C-shaped structure with circumferentially extending notches or gaps on its peripheral walls (e.g.,...). Figures 3 to 5B The slit 124 in the middle can, for example, be adapted to the terminal shape of the mating connector.

[0036] The socket and the corresponding connecting terminal may each be provided with a mating locking structure, so that after the connecting terminal is inserted into the socket, the locking structure will hold the connecting terminal in the socket. According to an exemplary embodiment of this disclosure, as... Figures 2 to 5B As shown, the socket 111 has a locking groove, such as a first locking groove 112 and a second locking groove 113. The locking groove can be a recess communicating with the interior of the socket. Correspondingly, a conductive positioning structure 123, such as a barb or fin, is provided on the outer peripheral surface of the outer conductor 122 of the connecting terminal 120. This structure can be integrally formed with the outer conductor itself, or it can be formed separately and connected to the outer conductor, protruding from the outer peripheral surface of the outer conductor 122. This protruding positioning structure can be elastic. When the connecting terminal 120 is inserted into the appropriate position in the corresponding socket 111, the positioning structure 123 engages with the first locking groove 112 or the second locking groove 113 of the corresponding socket 111 to position or retain the connecting terminal 120 in the corresponding socket 111. It is understood that the paired locking structures provided on the socket and the connecting terminal are not limited to this; for example, in some examples, a locking groove can be provided on the connecting terminal, while a paired protruding positioning structure can be provided in the socket.

[0037] According to an exemplary embodiment of this disclosure, at least two adjacent sockets 111 have first locking slots 112 that are connected to each other or formed integrally, and the connecting terminals 120 are adapted to be inserted into the corresponding sockets 111 in one of a variety of configurations or layouts. In a first configuration, such as Figure 4A and Figure 4B As shown, the positioning structure 123 of each connecting terminal 120 engages with the first locking groove 112 of the corresponding socket 111, and the positioning structures 123 of the connecting terminals 120 inserted into the at least two adjacent sockets 111 contact each other, so that the outer conductors 122 of the connecting terminals 120 inserted into the at least two adjacent sockets 111 are electrically connected to each other. In the second configuration, as... Figure 5A and Figure 5B As shown, the positioning structure 123 of each connection terminal 120 engages with the second slot 113 of the corresponding socket 111, and the positioning structures 123 of each connection terminal 120 are spaced apart from each other or do not contact each other, so that the outer conductors 122 of each connection terminal 120 are electrically isolated from each other.

[0038] In an exemplary embodiment, a plurality of sockets 111 may be arranged in one or more rows, wherein the first locking slots 112 of some or all of the adjacent sockets 111 in each row or at least one row are in communication with each other, such that, in a first configuration, the positioning structures 123 of the connecting terminals 120 inserted into the adjacent sockets 111 in each row or at least one row can contact each other, thereby electrically communicating the outer conductors 122 of these connecting terminals 120 with each other. As an example, a plurality of sockets 111 may be arranged in an array having multiple rows and columns, wherein the first locking slots 112 of the adjacent sockets 111 in each row or each column are in communication with each other. In the illustrated embodiment, as Figure 2 As shown, the first slot 112 of adjacent sockets 111 in each row is connected to each other.

[0039] When the outer conductor of the connecting terminal is not a completely closed shape, but rather a C-shaped shape with a notch or slit 124, some of the signal energy will dissipate to the outer conductor of the adjacent channel during signal transmission due to electromagnetic induction, resulting in energy loss and reducing the SI level. However, in the first configuration according to the present disclosure, the outer conductors 122 of the connecting terminal 120 inserted into the sockets 111 that are connected to each other in the first slot 112 are electrically connected, which can guide the lost energy back to the original channel, enhance the electromagnetic induction of the signal, and improve the SI level. For example, in... Figure 6A In the SI performance curves of the conventional multi-channel coaxial connector shown, the insertion loss IL = 1.11 dB @ 1.6 GHz, 1.82 dB @ 3.2 GHz; the return loss RL = -19.95 dB @ 1.6 GHz, -13.47 dB @ 3.2 GHz; according to the exemplary embodiments of the present disclosure, in the first configuration, both return loss and insertion loss are significantly improved, for example as... Figure 6B As shown, the insertion loss IL = 0.20dB@1.6GHz, 0.55dB@3.2GHz; the return loss RL = -22.11dB@1.6GHz, -14.9dB@3.2GHz, thereby improving the SI performance of the multi-channel coaxial connector and making it suitable for high-frequency applications.

[0040] In the second configuration, the outer conductors 122 of each connecting terminal 120 inserted into the socket 111 of the insulating body 110 are not electrically conductive or are electrically isolated from each other, and each outer conductor transmits current independently. This allows it to be used in applications where SI performance requirements are not high and high current transmission is required. Therefore, by using the multi-channel coaxial connector provided according to the embodiments of this disclosure, it is possible to easily switch between high SI performance and high current carrying capacity, improving application flexibility.

[0041] In such Figure 2 , Figure 4A and Figure 5AIn the illustrated embodiment, a plurality of sockets 111 disposed in the insulating body 110 of the connector are arranged in an array having multiple rows and columns. The sockets in each row are staggered with those in adjacent rows in the row direction X of the array or misaligned in the column direction Y of the array, thereby increasing the socket density. In other embodiments not shown, the sockets in adjacent rows may be aligned in the column direction Y of the array. It is understood that the arrangement of the sockets is not limited to this and can be appropriately arranged as needed or for the application, for example, in a concentric circle array.

[0042] As shown in the figure, the first locking groove 112 and the second locking groove 113 of the socket 111 are positioned at different positions along the circumference of the socket, thereby facilitating the insertion of the connection terminal 120 into the corresponding socket 111 in different configurations or layouts. For example, as... Figure 2 , Figures 4A to 5B As shown, the first locking groove 112 and the second locking groove 113 of the socket 111 can be arranged at positions 90 degrees apart along the circumference of the socket, thereby forming a locking groove that is generally cross-shaped. As an example, the first locking grooves 112 of the sockets 111 in the same row can be aligned in the row direction X, and the first locking grooves 112 of adjacent sockets 111 are connected to each other.

[0043] In such Figure 2 , Figures 4A to 5B In the illustrated embodiment, each socket 111 includes a pair of first locking slots 112 and a pair of radially opposite second locking slots 113. The pair of first locking slots 112 can be radially opposite to each other or have an angular spacing of less than 180 degrees. The pair of second locking slots 113 can also be radially opposite to each other or have an angular spacing of less than 180 degrees. On the outer peripheral surface of the outer conductor 122 of each connecting terminal 120, a pair of positioning structures 123 are provided. The pair of positioning structures 123 can be positioned radially opposite to each other and are adapted to engage with the pair of first locking slots 112 or the pair of second locking slots 113 of the corresponding socket 111 to realize different configurations or positions of the connecting terminals in the socket.

[0044] In embodiments not shown, the sockets and connecting terminals may also be provided with additional locking or engaging structures that mate with each other; for example, the sockets may also form a third locking slot, and the third locking slots of adjacent sockets in different rows (e.g., the same column) may communicate with each other. Correspondingly, the connecting terminals may be provided with a third positioning structure that mates with or engages with the third locking slot, and vice versa. Thus, in the first configuration, the third positioning structures of the connecting terminals inserted into adjacent sockets in different rows contact each other, causing the outer conductors of the connecting terminals inserted into different rows (e.g., the same column) to also be electrically connected to each other. This allows for the electrical connection of the outer conductors of some or all of the connecting terminals of the connector as needed, effectively improving SI performance. It will be understood that the aforementioned locking or engaging structures provided on the sockets and connecting terminals are positioned spaced apart from each other, enabling different configurations of the connector.

[0045] According to exemplary embodiments of this disclosure, such as Figure 4A and Figure 4B As shown, in a multi-channel coaxial connector, the positioning structures 123 of the connecting terminals 120 inserted into at least two adjacent sockets 111 of the insulating body 110 are in contact with each other. Preferably, the positioning structures 123 of adjacent connecting terminals 120 inserted into the same row or column of sockets 111 are in contact with each other. More preferably, the positioning structures 123 of adjacent connecting terminals 120 inserted into all sockets 111 are in contact with each other, so that the outer conductors 122 of these contacting connecting terminals 120 are electrically connected to each other, thereby enabling the lost energy to be returned to the original channel, enhancing the electromagnetic induction of the signal, and improving the SI level.

[0046] like Figure 7 As shown, embodiments of this disclosure also provide a connector assembly including a multi-channel coaxial connector 100 as described in any embodiment of this disclosure and a mating connector 200 adapted for electrical connection to the multi-channel coaxial connector 100. The mating connector 200 may include a plurality of mating terminals (not shown) for connection to the connection terminals 120 of the multi-channel coaxial connector 100. For example, the multi-channel coaxial connector 100 may be a wire-end connector adapted for connecting cables (such as coaxial cables), while the mating connector 200 includes a board-end multi-channel connector adapted for connecting a circuit board 2 (not shown) to electrical equipment.

[0047] Although embodiments of the present disclosure have been shown and described, it will be understood by those skilled in the art that variations can be made to these embodiments without departing from the principles and spirit of the present disclosure, the scope of which is defined by the appended claims and their equivalents. Those skilled in the art will also understand that the embodiments described above are exemplary and can be modified thereto, and the structures described in the various embodiments can be freely combined without conflict in structure or principle. Furthermore, it should be noted that, unless otherwise specified, the terms "comprising," "including," and "having" as used herein do not exclude other elements or steps. Additionally, any reference numerals in the claims should not be construed as limiting the scope of the present disclosure.
