[0024] To achieve the above objectives, this utility model provides the following technical solution:

[0030] 4. The design of the limiting channel not only guides the insertion of the plug assembly, but also provides space for the setting of the card slot. Detailed Implementation

[0032] The following will be combined with the appendix Figure 1 To be continued Figure 6 Description: A composite multi-channel connector (10) includes a plug assembly (11) and a socket assembly (12). The plug assembly (11) includes a plug insulator (111) and a plug housing (112). The plug insulator (111) is nested within the plug housing (112). Power pins (113) and signal pins (114) are distributed on the plug insulator (111).

[0033] The socket assembly (12) includes a socket insulator (121) and a socket housing (122). The socket insulator (121) is nested within the socket housing (122). The socket insulator (121) is provided with power sockets (123) and signal sockets (124). The plug housing (112) includes a fixing shell (1121) and a sleeve shell (1122). The outer end face of the fixing shell (1121) is provided with a retaining ring groove (1161), and the inner wall surface of the sleeve shell (1122) is provided with a retaining protrusion (1162) that matches the retaining ring groove (1161). The outer side surface of the plug housing (112) is provided with a snap-fit ​​portion (115). A limiting passage is formed between the axially extending portion of the socket insulator (121) of the socket assembly (12) and the inner wall surface of the socket housing (122). The socket housing (122) is provided with a slot (126) matching the buckle part (115) on the inner wall surface of the limiting channel (125); wherein, the buckle part (115) includes a first buckle (1151) provided on the side of the fixing shell (1121) and a second buckle (1152) provided on the side of the sleeve shell (1122), and the slot (126) includes a first slot (1261) matching the first buckle (1151) and a second slot (1262) matching the second buckle (1152); when the plug assembly (11) and the socket assembly (12) are connected in place, the first buckle (1151) is engaged in the first slot (1261) and the second buckle (1152) is engaged in the second slot (1262).

[0034] This utility model provides a composite multi-channel connector (10). The plug insulator (111) of the plug assembly (11) is typically made of insulating materials such as PBT or LCP, and has several power pins (113) and signal pins (114) fixed on it in a predetermined array or layout. These pins (113, 114) are used to conduct current or signals. The plug housing (112) is typically made of metal (such as zinc alloy or stainless steel) or reinforced plastic, and is used to protect the internal plug insulator (111) and pins (113, 114) and to provide an interface for mechanical connection. The plug housing (112) consists of a fixed shell (1121) and a sleeve shell (1122). The outer end face of the fixed shell (1121), that is, near the tail end of the plug assembly (11) connected to the cable or at a specific position, is provided with an annular retaining groove (1161). The sleeve (1122) is fitted onto the outside or part of the outside of the fixed shell (1121). The inner wall of the sleeve has one or more segments of locking protrusions (1162) at corresponding positions. The locking protrusions (1162) are embedded in the locking ring groove (1161), so that the sleeve (1122) can rotate relative to the fixed shell (1121) or slide axially within a certain range, or simply achieve the assembly and fixation between the two.

[0035] The socket assembly (12) also includes a socket insulator (121) and a socket housing (122). The socket insulator (121) is provided with power sockets (123) and signal sockets (124) corresponding to power pins (113) and signal pins (114), respectively. The internal structure of the socket housing (122) is ingeniously designed, with an annular or specifically shaped limiting channel (125) formed between the axially extending portion of the socket insulator (121) (e.g., the outer peripheral wall of the socket insulator (121)) and the inner wall surface of the socket housing (122). This limiting channel (125) is used to guide the insertion of the plug housing (112) and to accommodate the front end portion of the plug housing (112).

[0036] The key locking structure is that a latching part (115) is provided on the outer side of the plug housing (112). This latching part (115) is not a single structure, but consists of two parts: one part is a first latch (1151) provided on the side of the fixed shell (1121), and the other part is a second latch (1152) provided on the side of the sleeve shell (1122). Correspondingly, a groove (126) matching the latching part (115) is provided on the inner wall of the limiting channel (125) of the socket housing (122). This groove (126) is also divided into two parts: a first groove (1261) that cooperates with the first latch (1151) and a second groove (1262) that cooperates with the second latch (1152).

[0037] Working principle: When the plug assembly (11) is aligned with and inserted into the socket assembly (12), the power pin (113) and signal pin (114) are inserted into the power socket (123) and signal socket (124) respectively to achieve electrical connection. At the same time, the plug housing (112) enters the limiting channel (125). As insertion proceeds, the first latch (1151) on the fixed housing (1121) first or simultaneously engages with the first slot (1261) on the socket housing (122) and finally fits in. Immediately afterwards or after a specific operation (such as rotating the housing (1122) or pushing it in further), the second latch (1152) on the housing (1122) engages with the second slot (1262) on the socket housing (122). In this way, the cooperation between the first latch (1151) and the first slot (1261) and the cooperation between the second latch (1152) and the second slot (1262) achieves double locking, so that the plug assembly (11) and the socket assembly (12) are firmly connected together, effectively preventing accidental separation caused by vibration or external force.

[0038] Beneficial effects: By incorporating latches on both the fixed housing and the outer casing, which engage with corresponding slots on the socket, a double locking mechanism is achieved, significantly enhancing the reliability and stability of the connection. Simultaneously, the integrated design of the power and signal components saves space.

[0039] Please see Figures 1 to 6 In another embodiment, the width of the retaining ring groove (1161) of the fixed shell (1121) is greater than the width of the retaining protrusion (1162) of the sleeve (1122).

[0040] The axial width of the retaining ring groove (1161) of the fixed housing (1121) is designed to be larger than the axial width of the retaining protrusion (1162) on the inner wall of the sleeve (1122). For example, if the width of the retaining ring groove (1161) is W1 and the width of the retaining protrusion (1162) is W2, then W1 > W2. This design allows the sleeve (1122) to still have a certain amount of movement or travel in the axial direction (i.e., the insertion and removal direction) of the fixed housing (1121) after the retaining protrusion (1162) enters the retaining ring groove (1161).

[0041] Working principle and beneficial effects: This width difference allows for a certain relative axial displacement of the housing (1122) relative to the fixed housing (1121). This displacement can be used to: 1) facilitate the assembly process of the plug housing (112); 2) allow the housing (1122) to engage with the second latch (1152) during insertion and removal operations. For example, after the first latch (1151) is initially positioned, the housing (1122) can be pushed forward a short distance to fully lock the second latch (1152) into the second slot (1262), or during unlocking, the housing (1122) can be pulled back to disengage the second latch (1152). This design makes the locking process more intuitive.

[0042] Please see Figures 1 to 6 In another embodiment, the first card slot (1261) and the second card slot (1262) are connected by an inclined surface (1263).

[0043] The first slot (1261) and the second slot (1262) provided on the inner wall of the limiting channel (125) of the socket housing (122) are not completely isolated. Assuming that the first slot (1261) and the second slot (1262) have a certain positional difference in the axial direction (for example, the second slot (1262) is closer to the rear end of the socket assembly (12) or deeper than the first slot (1261), then there is a smoothly transitioning inclined surface (1263) between the two slots. When the plug assembly (11) is inserted, if the second latch (1152) contacts the slot area before the first latch (1151) or on a different path, or if the second latch (1152) needs to move further to enter the second slot (1262) after the first latch (1151) has entered the first slot (1261), this inclined surface (1263) can guide the second latch (1152) to slide smoothly from one position to and into the second slot (1262).

[0044] Working principle and beneficial effects: The inclined surface (1263) acts as a guide and transition. It ensures that the second latch (1152) experiences gentler force as it enters the second slot (1262), reducing jamming and wear, and making the insertion and removal operation smoother. Especially when the second latch (1152) needs to overcome a certain elastic resistance to enter the second slot (1262), the inclined surface (1263) can help to gradually compress or deform the second latch (1152), thereby successfully completing the locking. This improves the user experience and enhances the reliability of the connection.

[0045] Please see Figures 1 to 6In another embodiment, a gap (1163) is left between the inner wall surface of the part of the housing (1122) where the second buckle (1152) is provided and the outer wall surface of the fixing housing (1121).

[0046] When the sleeve (1122) is assembled onto the fixed shell (1121), the inner wall of the area on the sleeve (1122) where the second buckle (1152) is provided is not completely fitted with the corresponding outer wall of the fixed shell (1121), but a certain radial gap (1163) is intentionally retained. This gap (1163) can be circumferential or localized.

[0047] Working principle and beneficial effects: The existence of this gap (1163) provides a certain radial deformation space for the part of the housing (1122) with the second snap (1152). When the second snap (1152) interferes with the second slot (1262) of the socket housing (122) or its guiding structure (such as the inclined surface 1263), this part of the housing (1122) can undergo slight elastic deformation inward (towards the fixed housing (1121)) or outward, without causing deformation difficulties or damage due to direct contact with the fixed housing (1121). This enhances the flexibility and reliability of locking and unlocking the second snap (1152).

[0048] Please see Figures 1 to 6 In another embodiment, the gap (1163) extends circumferentially, and the second snap (1152) for the housing (1122) achieves radial elastic deformation when engaged with the second slot (1262) of the socket housing (122).

[0049] The gap (1163) extends circumferentially along the housing (1122), that is, there is a pre-set radial gap between the inner wall of the housing (1122) where the second buckle (1152) is located and the outer wall of the fixing shell (1121) on the entire or most of the circumference.

[0050] Working principle and beneficial effects: This circumferentially extending gap (1163) clearly defines its function: when the plug assembly (11) and the socket assembly (12) are engaged, the second latch (1152) on the housing (1122) needs to overcome the obstruction of the edge of the slot during the process of entering or disengaging from the second latch (1262). Due to the presence of the gap (1163), the part of the housing (1122) that supports the second latch (1152) can undergo radial elastic deformation. This elastic deformation is the key to achieving a "click" locking or unlocking, making the connection more secure, while providing a good operating feel and compensating for certain manufacturing tolerances, ensuring that the second latch (1152) can work reliably.

[0051] Furthermore, the outer side of the plug housing (112) is provided with at least two sets of the latching portions (115) spaced apart in the circumferential direction, and the inner wall surface of the socket housing (122) located in the limiting channel (125) is provided with at least two sets of the slots (126) spaced apart in the circumferential direction to match the latching portions (115).

[0052] The outer surface of the plug housing (112) is not just a single set of latching parts (115) (each set of latching parts (115) includes a first latch (1151) and a second latch (1152)). Instead, at least two sets of such latching parts (115) are evenly or non-evenly spaced along the circumference of the plug housing (112). For example, two sets can be provided, which are 180 degrees apart on the circumference; or three sets can be provided, which are 120 degrees apart on the circumference. Correspondingly, the socket housing (122) also has at least two sets of slots (126) (each set of slots (126) includes a first slot (1261) and a second slot (1262)) spaced along the circumference on the inner wall surface of its limiting channel (125).

[0053] Working principle and beneficial effects: By setting multiple sets of latching parts (115) and slots (126) in the circumferential direction, the force on the plug assembly (11) and socket assembly (12) after connection can be more uniform, and the torsional resistance and overall connection strength are significantly improved. Multi-point locking also further enhances the reliability of the connection. Even if one latching point is slightly loosened due to accident, the other latching points can still maintain the connection firmly, effectively preventing the plug from shaking radially or accidentally rotating out.

[0054] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
