[0021] Please see Figures 1 to 6 A multi-connector according to an embodiment of the present invention is characterized in that it includes: an outer mold (1) with a rubber coating, wherein the outer mold (1) has connecting parts (11) symmetrically arranged on both sides, and the connecting parts (11) are connected by a channel (12); an inner mold (2) with a rubber coating, wherein the inner mold (2) has at least one mounting groove (21), and the outer mold (1) is fitted onto the inner mold (2); at least one conductive element (3), each conductive element (3) including a copper busbar (31) and copper pins (32) disposed on the left and right sides of the copper busbar (31), each copper busbar (31) being embedded in a corresponding mounting groove (21); and a mating body (4), wherein the mating body (4) is disposed on the connecting part (11), and the mating body (4) has at least one connecting through hole (41), and the copper pins (32) on the at least one conductive element (3) are embedded in the corresponding connecting through hole (41).
[0022] See attached document Figures 1 to 6 This utility model discloses a multi-connector, whose outer mold (1) is injection molded from insulating plastic material, providing basic shell protection and structural support for the connector. Both sides of the outer mold (1) are provided with symmetrical connecting parts (11) in structure and size, meaning the connector can mate with external components in two opposite directions, providing bidirectional connection capability. These connecting parts (11) are connected by a hollow channel (12) penetrating the interior of the outer mold (1), allowing cables or other connecting components to extend from one connecting part (11) to another, or providing structural continuity and support for internal components. This design allows the connector to be flexibly applied to various scenarios such as series connection, parallel distribution, or dual-interface access, significantly enhancing the connector's flexibility and the system's wiring convenience.
[0023] Inside the outer mold (1), the inner mold (2) is fitted. The inner mold (2) is also made of insulating plastic material and has at least one mounting groove (21) extending in a specific direction. The outer mold (1) completely covers the outer mold (2), forming a double-layer insulating protection structure, which effectively improves the electrical safety performance and overall mechanical strength of the connector, while ensuring the precise positioning of the internal conductive components.
[0024] The core conductive function of the connector is achieved by at least one conductive element (3). Each conductive element (3) consists of a flat copper busbar (31) and multiple copper pins (32), which are fixedly installed on the left and right sides along the length of the copper busbar (31). Each copper busbar (31) is firmly fixed in a corresponding mounting groove (21) within the overmolded inner mold (2) by embedding. This fixing method ensures the stability of the copper busbar (31) inside the connector, preventing displacement or rotation, thereby ensuring continuous and reliable electrical contact. This design not only improves the reliability of the connection but also facilitates the carrying of larger operating currents.
[0025] The mating body (4) is an interface component for the connector to be inserted into an external mating connector or cable terminal, and it is fixed at the connection part (11) of the rubber-coated outer mold (1). The mating body (4) has at least one connection through hole (41), the size and position of which match the copper pins (32) on the conductive element (3). When the mating body (4) is installed and an external connector is inserted, the copper pins (32) on the conductive element (3) will precisely pass through and embed into the corresponding connection through hole (41) on the mating body (4), thereby forming a reliable electrical contact with the conductive terminal of the external connector and constituting a complete electrical path. This structure ensures that electrical signals or energy can be transmitted directly and reliably during mating.
[0026] Through the specific structural combination and mutual cooperation of the above components, a multi-connector basic platform with strong structural versatility, comprehensive protection and clear conductive path is provided. Its symmetrical connection part and internal channel design make it possible for a variety of connection methods and extended applications, while ensuring the reliability of electrical connection and the stability of structure.
[0027] Please see Figures 1 to 6 The inner mold (2) is provided with a channel (22) in the middle, and the outer mold (1) is provided with a fixing hole (13) in the middle. When the outer mold (1) is fitted onto the inner mold (2), the outer wall of the fixing hole (13) fits into the channel (22).
[0028] Based on the above embodiments, in order to achieve convenient and secure installation of the connector, this utility model further defines the installation structure. Specifically, the inner mold (2) is provided with one or more recessed channels (22) at approximately its middle side. Correspondingly, the outer mold (1) is provided with one or more fixing holes (13) penetrating its wall thickness at approximately its middle position, corresponding to the area of the channel (22) of the inner mold (2). When the outer mold (1) is fitted onto the inner mold (2) for assembly, the edge of the fixing hole (13) or the outer wall of the channel formed therein will fit or embed with the channel (22) on the inner mold (2). This fit not only plays a guiding and positioning role during assembly, but more importantly, the user can use screws or other fasteners through the fixing hole (13) to fix the entire connector to the external support surface such as the equipment housing, wall, or mounting plate. The channel (22) can provide countersunk holes for the head of the fastener or provide support and restraint for the structure around the fixing hole (13), enhancing the stability and anti-rotation capability of the installation.
[0029] The advantage of this structure is that it provides a simple, effective, and reliable installation method, which allows the connector to be firmly installed in the required position, avoiding loosening or falling off due to vibration or external force, thereby ensuring the long-term stability and reliability of the connection system in fixed installation applications.
[0030] Please see Figures 1 to 6 The copper needle (32) is riveted to the copper busbar (31).
[0031] To ensure the electrical performance and mechanical strength of the connection between the copper pin (32) and the copper busbar (31) inside the conductive component (3), this invention preferably employs a riveting process. Specifically, the base of the copper pin (32) is designed with a riveting structure, while the copper busbar (31) has corresponding mating holes or positioning points. During assembly, after the copper pin (32) is inserted into the corresponding position of the copper busbar (31), pressure is applied by the riveting equipment to cause plastic deformation of the base metal of the copper pin (32), thereby forming a tight, non-removable mechanical and electrical connection with the copper busbar (31). This riveting connection method is a cold-working connection, avoiding the influence of high-temperature symmetrical material properties that may occur during welding, and the resulting connection point has low contact resistance, excellent conductivity, and high tensile strength and vibration resistance.
[0032] The beneficial effect of this structure is that by fixing the copper pin (32) to the copper busbar (31) through the riveting process, a high-strength and highly conductive permanent connection between the two is achieved, ensuring the electrical continuity and structural stability of the conductive path during long-term use, and significantly improving the overall durability and current carrying capacity of the connector.
[0033] Please see Figures 1 to 6 The outer side of the port where the interlocking body (4) connects to the outer mold (1) is provided with a fixing slot (42), and the inner wall of the outer mold (1) is provided with a snap protrusion 1 (4) that matches the fixing slot (42).
[0034] To enhance the bonding strength between the mating body (4) and the outer mold (1) and prevent the mating body (4) from loosening or coming off under pulling force or external vibration, this utility model designs a snap-fit locking structure. Specifically, the mating body (4) and the inner mold (2) are assembled through strong interference, and then the outer mold (1) completely covers the inner mold (2), partially covering the mating body (4). When the outer mold is wrapped, the glue will be fixed in the groove (42), so that the snap protrusion (14) is fixed with the groove (42), which plays a limiting role.
[0035] The beneficial effect of this structure is that by cooperating with the fixed slot (42) and the locking protrusion (14), the mating body (4) is firmly locked in the outer mold (1), which effectively prevents accidental separation and improves the overall mechanical stability and connection reliability of the connector. It is especially suitable for application environments that require resistance to vibration or a certain insertion and extraction force.
[0036] Please see Figures 1 to 6 The mating body (4) has three connecting through holes (41) evenly arranged; the inner mold (2) is provided with three mounting grooves (21), and each mounting groove (21) is provided with a copper busbar (31); the copper pins (32) provided on the three copper busbars (31) are respectively embedded in the three connecting through holes (41) when the mating body (4) is placed on the outer mold (1).
[0037] To achieve a clear multi-path parallel connection function, this utility model specifically limits the number of conductive paths to three. Specifically, on the insertion surface of the mating body (4), three independent connecting through holes (41) are evenly provided along a certain pattern (e.g., straight line arrangement or triangular arrangement), each connecting through hole (41) corresponding to the transmission of one electrical signal or power supply. Correspondingly, the interior of the rubber-coated inner mold (2) is also provided with three independent mounting slots (21), the layout of which corresponds to the spatial position of the three connecting through holes (41) on the mating body (4). Each mounting slot (21) is embedded with an independent copper busbar (31), meaning there are three copper busbars (31) installed in the three mounting slots (21), forming three independent conductive base layers. Copper pins (32) are provided on both the left and right sides of each copper busbar (31). When the mating body (4) is installed on the connecting part (11) of the rubber-coated outer mold (1), the copper pins (32) from the first copper busbar (31) will be inserted into the first connecting through hole (41), the copper pins (32) from the second copper busbar (31) will be inserted into the second connecting through hole (41), and the copper pins (32) from the third copper busbar (31) will be inserted into the third connecting through hole (41), thus forming three parallel and mutually insulated electrical paths. This uniform arrangement is beneficial to the stable transmission of signals and the space utilization of the structure.
[0038] The beneficial effect of this structure is that, through the precise matching of three sets of independent conductive parts (3) with the corresponding three connection through holes (41) on the mating body (4), this connector can transmit three independent electrical signals or power supplies simultaneously in a compact integrated unit, which greatly improves the connection density and wiring efficiency, and simplifies the system design in application scenarios that require multiple parallel connections.
[0039] Beneficial effects
[0040] In summary, through the above structural design, this utility model has at least the following beneficial effects:
[0041] 1. Sturdy and reliable structure: The combination of inner and outer encapsulation molds and the snap-fit structure between the mating body and the outer mold ensure the overall mechanical strength and connection stability of the connector.
[0042] 2. Easy installation: By setting fixing holes in the outer mold and cooperating with the inner mold groove, the connector can be easily fixed and installed on various surfaces.
[0043] 3. High-efficiency multi-channel transmission: By setting multiple sets of parallel conductive components and corresponding connection through holes, parallel transmission of multiple signals or power supplies can be integrated into a single connector, thereby improving connection density.
[0044] 4. Excellent conductivity: The conductive structure of copper busbars and riveted copper pins ensures low contact resistance, high current carrying capacity, and long-term electrical connection reliability.

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.
