Description

Technical Field

[0001] This invention relates to the field of connectors, and particularly to a mating assembly. Background Technology

[0002] With the increasing integration of power and electronic equipment, the electrical connection requirements between various devices are becoming more complex, placing higher demands on the reliability, miniaturization, and flexibility of connectors. In many application scenarios, connectors must have anti-misfit functionality, ensuring that plugs and sockets of different specifications or uses cannot be incorrectly connected to prevent circuit misconnection, equipment damage, or even safety accidents.

[0003] Traditional anti-misfit designs generally employ external structural foolproofing. A common practice is to incorporate specific guide keys, positioning posts, or asymmetrical contours onto the connector's metal or plastic housing. While these physical structures protruding from the housing provide basic anti-misfit identification, they also introduce significant drawbacks. First, external foolproofing structures inevitably increase the overall size of the connector, occupying valuable equipment installation space, which contradicts the trend towards miniaturization and high-density layouts in modern devices. Second, such designs typically integrate the foolproofing function with the housing itself. When adapting to sockets with different coding requirements, plugs with different overall structures must be used, resulting in a wide variety of components, poor versatility, and increased procurement and maintenance costs for users. Furthermore, if the foolproofing structure is damaged during use, the entire plug assembly often needs to be replaced, making maintenance inconvenient and uneconomical.

[0004] Therefore, there is an urgent need for an innovative connector design that can effectively overcome the drawbacks of traditional external misfitting structures, such as increased size, low versatility, and difficult maintenance, while ensuring reliable anti-misfitting functionality.

[0023] Please refer to the reference. Figures 1 to 10 As shown, the present invention proposes a plug-in assembly 100, including a socket and a plug; the plug includes a plug housing 10, the plug housing 10 having a mounting cavity 10a, a core 20 being installed in the mounting cavity 10a, the core 20 having a plug groove 20a extending in a first direction and a slot 20b extending in a second direction, the plug groove 20a communicating with the slot 20b, a copper busbar terminal 30 being inserted into the slot 20b, and the groove wall of the plug groove 20a having a plurality of coding grooves 20c; The socket includes a socket housing 40, on which a plug post 41 is provided. The plug post 41 is provided with a connecting groove 41a, and a copper busbar assembly 50 is provided in the connecting groove 41a. The outer wall of the plug post 41 is provided with a plurality of coding protrusions 42 corresponding to the coding groove 20c. When the socket is plugged into the plug, the plug post 41 is inserted into the plug groove 20a, and the coding protrusions 42 are inserted into the coding groove 20c, so that the copper busbar assembly 50 is connected to the copper busbar terminal 30.

[0024] Understandably, the plug assembly 100 includes a socket and a plug, the plug including a plug housing 10. Preferably, the plug housing 10 is integrally molded from insulating rigid plastic. The insertion direction from the plug to the socket is defined as the first direction (X-axis), the extension direction of the copper busbar terminal 30 from the insertion end 31 to the connection end 33 is defined as the second direction (Y-axis), and the third direction (Z-axis) is perpendicular to the first and second directions, forming a right-hand rectangular coordinate system. The plug housing 10 has an installation cavity 10a along the first direction and a receiving cavity 10b along the second direction, wherein the installation cavity 10a and the receiving cavity 10b are connected. A rubber core 20 is installed in the installation cavity 10a. Preferably, the rubber core 20 is installed in the installation cavity 10a from the opening of the installation cavity 10a in the opposite direction to the first direction. The rubber core 20 has a insertion groove 20a extending along the first direction and a slot 20b extending along the second direction, the insertion groove 20a and the slot 20b being connected. After the core 20 is installed in the mounting cavity 10a, the copper busbar terminal 30 is inserted into the receiving cavity 10b from the cavity opening in the opposite direction of the second direction until one end of the copper busbar terminal 30 is inserted into the slot 20b. The other end of the copper busbar terminal 30 is connected to the power cable by welding, crimping, or screw fixing. The wall of the plug slot 20a is provided with a plurality of coded slots 20c in a specific arrangement, which constitute the built-in identification feature on the plug side. The socket includes a socket housing 40. Preferably, the socket housing 40 is integrally molded from insulating rigid plastic. An insertion post 41 protruding in the first direction is integrally formed or fixedly installed on the socket housing 40, and the insertion post 41 is provided with a connecting slot 41a. The socket also includes a copper busbar assembly 50, one end of which is used for electrical connection with an external power cable by welding, crimping, or screw fixing, and the other end is accommodated in the connecting slot 41a as a contact part. On the outer peripheral wall of the plug 41, multiple coding protrusions 42 are formed, corresponding in size, position, and number to the coding slots 20c of the plug groove 20a. The arrangement of the coding protrusions 42 corresponds one-to-one with the arrangement of the coding slots 20c. When the plug and socket are plugged in, the plug 41 is inserted into the plug groove 20a in the opposite direction to the first direction. During this process, the coding protrusion 42 can only be successfully embedded into the corresponding coding slot 20c when the coding protrusion 42 of the socket is fully matched with the coding slot 20c on the plug core 20. As the plug 41 is successfully inserted into the plug groove 20a, the copper busbar assembly 50 in the connecting groove 41a extends into the slot 20b and contacts the copper busbar terminal 30 in the slot 20b, thereby realizing the electrical connection between the plug and the socket.

[0025] In an embodiment of the present invention, the end of the core 20 away from the slot of the insertion groove 20a is provided with a fixing surface 21, the core 20 has a top surface 22 and a bottom surface 23 arranged opposite to each other along the second direction, and the slot 20b passes through the fixing surface 21 and the bottom surface 23.

[0026] Understandably, the core 20 has a fixing surface 21 at the end away from the opening of the insertion slot 20a for mounting, positioning, and / or fixing to other components; the core 20 has a top surface 22 and a bottom surface 23 spatially opposite each other along the second direction, wherein the slot 20b passes through the fixing surface 21 and the bottom surface 23, so that the slot 20b opens into the fixing surface 21 and the bottom surface 23 and communicates with the insertion slot 20a. The copper busbar terminal 30 is inserted into the slot 20b from the bottom surface 23 downwards along the opposite direction of the second direction.

[0027] In an embodiment of the present invention, the adhesive core 20 has two side walls 24 disposed opposite to each other along a third direction, the side walls 24 are provided with limiting protrusions 241, and the cavity wall of the mounting cavity 10a is provided with limiting grooves corresponding to the limiting protrusions 241; and / or, the end of the adhesive core 20 away from the fixing surface 21 is provided with a boss 25 in the radial direction.

[0028] Understandably, the core 20 has two side walls 24 arranged opposite each other along a third direction. Each side wall 24 is provided with a limiting protrusion 241. The cavity wall of the mounting cavity 10a is provided with a matching limiting groove corresponding to the position of each limiting protrusion 241. The limiting protrusion 241 cooperates with the limiting groove to limit the movement of the core 20 in the mounting cavity 10a along the first direction. Optionally, the core 20 extends radially outward at the end away from the fixing surface 21 to form a boss 25. The boss 25 is used to abut against the end of the plug housing 10 when the core 20 is inserted into the mounting cavity 10a to limit the insertion depth of the core 20 and provide axial positioning.

[0029] In an embodiment of the present invention, the plug further includes a fixing member 60, the fixing member 60 including a connecting part 61, one end of the connecting part 61 is provided with a fixing part 62, and the other end of the connecting part 61 is provided with an abutting part 63; the fixing surface 21 of the core 20 is provided with an abutting groove 20d, the abutting groove 20d is connected to the slot 20b, the copper bus terminal 30 is provided with a relief groove 30a corresponding to the abutting groove 20d, the fixing part 62 is fixedly connected to the core 20, and the abutting part 63 abuts in the abutting groove 20d and abuts in the relief groove 30a.

[0030] Understandably, the plug also includes a separate fixing component 60. This fixing component 60 is mainly used to fix and limit the copper busbar terminals 30 inside the plug housing 10, preventing accidental movement or loosening during insertion, removal, or use. Specifically, the fixing component 60 is an integrally molded part, its main body being a connecting portion 61 extending along the second direction. One end of the connecting portion 61 forms a fixing portion 62, used to securely install the fixing component 60 itself onto the core 20. The fixing portion 62 can take the form of a snap-fit, screw connection, interference fit column, or rod-shaped body, etc. At the other end of the connecting portion 61 away from the fixing portion 62, an abutment portion 63 is formed. This abutment portion 63 is typically designed as a part with a certain thickness or protruding structure, used to directly interfere with or abut against the copper busbar terminals 30. To accommodate and guide the abutment portion 63 of the fixing component 60, an abutment groove 20d is specially formed on the fixing surface 21 of the core 20. The abutment groove 20d communicates with the slot 20b for accommodating the copper busbar terminal 30, allowing the abutment portion 63 of the fastener 60 to at least partially extend into a portion of the space in the slot 20b through this groove. Correspondingly, at the location where the copper busbar terminal 30 needs to be positioned, a clearance groove 30a is pre-machined or stamped to form corresponding to the abutment groove 20d on the core 20. This clearance groove 30a is a recessed structure, sized to allow the abutment portion 63 of the fastener 60 to at least partially extend into it. During assembly, the fastening portion 62 of the fastener 60 is first fixedly connected to the core 20. During this process, the abutment portion 63 of the fastener 60 will be located within the abutment groove 20d on the core 20. Then, the core 20 with the fastener 60 installed is inserted into the mounting cavity 10a in the opposite direction to the first direction. As the core 20 is installed, the limiting protrusion 241 is connected to the limiting groove, and the boss 25 abuts against the end of the plug housing 10. Then, the copper busbar terminal 30 is inserted into the slot 20b of the core 20 from the receiving cavity 10b in the opposite direction to the second direction. When the copper busbar terminal 30 is pushed into the bottom of the slot 20b in the opposite direction to the second direction, the relief groove 30a on the copper busbar terminal 30 is approximately aligned with the abutment groove 20d on the core 20. Subsequently, the abutment portion 63 of the fixing member 60 is finally embedded or abutted in the relief groove 30a of the copper busbar terminal 30, thereby fixing the copper busbar terminal 30 and preventing the copper busbar terminal 30 from shaking in the second direction.

[0031] In an embodiment of the present invention, the copper bus terminal 30 includes a plug-in end 31, a transition end 32 and a connecting end 33 connected in sequence, and the clearance groove 30a is provided on the side of the plug-in end 31 near the fixing surface 21.

[0032] Understandably, the copper busbar terminal 30 is a conductive metal component, comprising a plug-in end 31, a transition end 32, and a connecting end 33 connected in sequence. The plug-in end 31 is located at the top of the copper busbar terminal 30, and its shape and size are configured to fit and smoothly insert into the slot 20b, and to contact the copper busbar assembly 50 to form an electrical connection. The connecting end 33 is located at the tail end of the copper busbar terminal 30 and is used for electrical and mechanical connection with external cables. The specific form of connection between the connecting end 33 and the cable can be bolted, crimped, or welded. The transition end 32 connects between the plug-in end 31 and the connecting end 33, serving as a structural transition and mechanical buffer area. Understandably, the shape of the transition end 32 has appropriate bends, reinforcing ribs, or a gradual width change to balance electrical current carrying requirements and mechanical strength, ensuring that stress can be smoothly transmitted when subjected to insertion / extraction forces or vibrations, and avoiding stress concentration at the root of the plug-in end 31 or the connecting end 33. In order to limit the copper busbar terminal 30, a clearance groove 30a is provided on the side of the plug end 31 near the fixing surface 21 of the core 20, so as to facilitate the contact part 63 to contact it.

[0033] In an embodiment of the present invention, the fixing part 62 is two wing-shaped structures arranged opposite to each other, and the glue core 20 is provided with two fixing grooves 20e corresponding to the fixing part 62, and the fixing part 62 is inserted into the fixing grooves 20e.

[0034] Understandably, the fixing portion 62 of the fastener 60 is specifically designed as two opposing wing-like structures. These two wing-like structures extend from the end of the connecting portion 61 away from the abutment portion 63 along a first direction. Each wing-like structure can be understood as a sheet-like or plate-like protrusion with a specific width, thickness, and profile, resembling a wing in shape, hence the term "wing-like." Its outer profile can be rectangular, trapezoidal, or have a chamfered shape, and possesses a certain structural strength and elasticity. Correspondingly, two fixing grooves 20e are provided on the housing of the core 20 in the area corresponding to the installation position of the fastener 60. The position, shape, and spacing of these two fixing grooves 20e are configured to correspond one-to-one with and perfectly match the two wing-like structures of the fixing portion 62. Understandably, the fixing grooves 20e can be located on the fixing surface 21, or they can be located on the side wall 24 adjacent to the fixing surface 21. The fixing grooves 20e are grooves with a certain depth, and their internal dimensions allow the wing-like structures to be smoothly inserted. During assembly, the operator aligns the two wing-shaped structures (i.e., the fixing parts 62) of the fastener 60 with the two fixing grooves 20e on the core 20 and applies pressure in a predetermined direction, causing the two wing-shaped structures to be inserted into their respective fixing grooves 20e. Once the wing-shaped structures are fully inserted, a secure mechanical connection is achieved between the fastener 60 and the core 20 through this plug-in engagement.

[0035] In an embodiment of the present invention, the fixing groove 20e is located on the fixing surface 21 and is disposed opposite to each other on both sides of the slot 20b.

[0036] Understandably, the two fixing grooves 20e on the core 20 are directly formed on the fixing surface 21 and are symmetrically arranged on the left and right sides of the slot 20b. This arrangement allows the two wing-shaped structures of the fastener 60 to be inserted parallel to the fixing grooves 20e from both sides of the slot 20b, thereby stably "straddling" the fastener 60 above the slot 20b. This ensures that the force borne by the fastener 60 is evenly distributed to the core 20 through the wing-shaped structures on both sides, avoiding unilateral force and significantly improving the stability and torsional resistance of the connection.

[0037] In an embodiment of the present invention, the fixing part 62 is provided with two oppositely arranged fixing edges 621 along the second direction, and the fixing edges 621 are serrated.

[0038] Understandably, the fixing edges 621 of each wing-shaped structure of the fixing part 62 along the second direction are constructed in a serrated shape. These serrations, when the wing-shaped structure is inserted into the fixing groove 20e, can form a tight engagement with the groove wall, thereby enhancing the mechanical locking force of the connection. The serrated edges effectively resist accidental withdrawal of the fixing member 60 from the fixing groove 20e and suppress its lateral wobbling within the groove, thus greatly improving the reliability and long-term stability of the connection between the fixing member 60 and the adhesive core 20.

[0039] In an embodiment of the present invention, the fixing groove 20e is E-shaped, and the irregular edges of the two fixing grooves 20e are arranged opposite each other.

[0040] Understandably, the fixing groove 20e on the core 20 is constructed in an E-shape, meaning its groove outline mimics the letter "E," featuring a main groove and several (usually three) inwardly protruding limiting teeth. The two E-shaped fixing grooves 20e are arranged in a mirror-symmetrical layout on the fixing surface 21, with their irregularly contoured sides (i.e., the open or toothed side of the E-shape) facing each other, both pointing towards the central slot 20b area. This special shape design allows the irregular edges of the E-shape to form multiple points of contact with the fixing part 62, greatly increasing the mechanical locking points and making the installation of the fixing member 60 on both sides of the slot 20b more secure and vibration-resistant.

[0041] In an embodiment of the present invention, one end of the copper busbar assembly 50 is provided with an elastic terminal 51, which is installed in the connecting groove 41a.

[0042] Understandably, one end of the copper busbar assembly 50 is provided with a resilient terminal 51, which is reliably installed within the connecting groove 41a. The resilient terminal 51 is typically made of a metallic material with good conductivity and elasticity, and its structure is designed such that at least a partial contact area has elastic deformation capability, thereby enabling a tight and adaptive electrical contact with the copper busbar terminal. Preferably, the resilient terminal 51 includes two opposing resilient components, with an elastic clamping area formed between the two components. When the socket and plug are fully inserted, the insertion end 31 of the copper busbar terminal 30 is precisely accommodated within the elastic clamping area, allowing a reliable and stable electrical connection to be established between the copper busbar assembly 50 and the copper busbar terminal 30 through elastic contact, effectively compensating for fit tolerances and ensuring low contact resistance and good vibration resistance. Preferably, the copper busbar assembly 50 is also provided with a resilient protrusion 52, and the connecting groove 41a is also provided with a snap-fit ​​groove. When the copper busbar assembly 50 is fully installed, the resilient protrusion 52 snaps into the snap-fit ​​groove to prevent the copper busbar assembly 50 from falling off along the first direction.

[0043] Understandably, the plug also includes a first sealing ring 71 and a tail cap 72. The first sealing ring 71 is housed in the receiving cavity 10b, and the tail cap 72 covers the opening of the receiving cavity 10b and is fixedly connected to the tail of the plug housing 10, thereby sealing the opening and preventing the first sealing ring 71 from falling off, forming a reliable sealing structure. The socket also includes a second sealing ring 81, and the socket housing 40 also includes a mounting panel 43. The mounting panel 43 has a mounting hole 44, and a sealing groove 45 is provided at the end of the mounting panel 43 away from the plug post 41. The second sealing ring 81 is housed in the sealing groove 45. When the socket housing 40 is installed on the main body, since the second sealing ring 81 is located between the mounting panel 43 and the main body, it prevents water from entering the interior of the socket housing 40 from between the main body and the mounting panel 43, ensuring the waterproof performance of the socket. Understandably, the main body and the socket can be fixedly connected by inserting fasteners 82 sequentially into the mounting hole 44 and the main body. Preferably, the socket also includes a waterproof gasket 83, which is disposed within the mounting hole 44 and fitted over the fastener 82. A handle assembly is also provided on the plug housing 10.

[0044] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
