Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, specifically to multifunctional connectors. Background Technology

[0002] In automated equipment, production lines, and complex electromechanical systems, numerous high-voltage electrical lines, low-voltage control lines, and pneumatic pipelines require connection. Currently, the common connection method is a separate connection using individual connectors, terminals, and pneumatic fittings. This traditional method has several drawbacks: First, construction is cumbersome, requiring separate wiring and connections, which is prone to errors, demands high operator expertise, and results in long installation and commissioning cycles. Second, during equipment maintenance, relocation, or modification, multiple lines and pipelines must be disconnected one by one, which is inconvenient, inefficient, and prone to loosening and poor contact due to repeated plugging and unplugging. Finally, the dispersed arrangement of various cables and pipelines not only occupies a large amount of space but also appears cluttered, hindering troubleshooting and routine maintenance, and affecting the overall aesthetics and standardization of the equipment.

[0003] While some multi-core electrical connectors exist in existing technologies, their functions are limited, only capable of transmitting electrical energy or signals, and they cannot integrate pneumatic circuits. Devices that achieve hybrid electrical and pneumatic transmission are typically complex in structure, bulky in size, inconvenient to plug and unplug, and lack simple and effective anti-loosening locking mechanisms. They are prone to loosening in vibration environments, affecting connection reliability. Therefore, there is an urgent need for an integrated connection solution that can highly integrate high-voltage, low-voltage, and pneumatic interfaces, enabling fast and reliable connection and locking, while simplifying wiring and facilitating construction and maintenance. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a multifunctional connector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, a specific embodiment of the present invention provides a multifunctional connector, including a male connector, a female connector, and a connector base. The male connector has a cylindrical portion with an annular groove on the inner wall of its end, and multiple metal pins are disposed inside the groove. The female connector has a cable interface portion for connecting to an external cable and a protrusion at one end formed to fit the groove. The protrusion has a metal insertion hole inside that matches the metal pins. The connector base has an L-shaped structure with a slot on its vertical portion. The protrusion of the female connector passes through this slot and engages with the groove at the end of the cylindrical portion of the male connector. Simultaneously, the metal pins are inserted into the metal insertion hole to electrically and mechanically connect the male and female connectors. The horizontal portion of the connector base serves as a mounting base for fixing the entire connector to a device.

[0006] The multi-functional connector of this application embodiment provides a multi-functional connector that is compact in structure, fast and reliable in connection, highly integrated and easy to install and maintain.

[0007] In addition, the multifunctional connector proposed in this application may also have the following additional technical features: In one embodiment of this application, at least one connecting lug is provided on the outer side of both the cylindrical portion of the male connector and the cable interface portion of the female connector, and the connecting lug is provided with a through hole.

[0008] In one embodiment of this application, a fixing plate is provided on the vertical side of the connector, and a locking bolt is provided on the fixing plate; when the male and female heads are engaged with the protrusion through the slot, the locking bolt can pass through the through holes of the male head's connecting lug, the fixing plate, and the female head's connecting lug in sequence and lock them, so as to fix the male head, female head and connector together.

[0009] In one embodiment of this application, the axis of the locking bolt is perpendicular to the axis of the protrusion passing through the slot.

[0010] In one embodiment of this application, the male head further has a frustoconical portion connected to the cylindrical portion.

[0011] In one embodiment of this application, the mounting base of the connector has at least one mounting hole.

[0012] In one embodiment of this application, the cable interface portion of the female connector is a multi-hole interface for connecting multiple independent wires.

[0013] In one embodiment of this application, the metal pins are arranged in an arc shape inside the cylindrical portion.

[0014] The advantages of this invention compared to existing technologies are: (1) Through the ingenious design of the male and female connectors and the connector, the high-voltage and low-voltage interfaces of the equipment can be integrated into one connection point, and the integrated air circuit interface can be expanded. During construction, only the centralized wiring inside the connector needs to be completed. On-site, only one plug-in and unplug operation is required to complete the connection or disconnection of all lines, which greatly simplifies the wiring process, reduces the wiring error rate, and significantly shortens the installation, debugging and relocation cycle.

[0015] (2) The initial quick connection and mechanical interlock are achieved by using the slot and the protrusion to engage, and then the secondary fastening is achieved by the engagement of the connecting lug and the locking bolt. This double fixing method ensures that the connection will not loosen under vibration environment and the electrical contact is stable and reliable. The connector achieves unified bearing and fixing of male and female heads, and the overall structure has good rigidity.

[0016] (3) All wire harnesses are centrally processed inside the connector, and external cables are uniformly led out through the female head, making the wire harnesses inside and outside the equipment neat and standardized, which is convenient for finding and tracking. During maintenance, only one locking bolt needs to be loosened to separate the entire female head (along with all external cables) from the male head. The operation is extremely convenient and there is no need to process each wire or air pipe individually.

[0017] (4) The structure is modular and can be configured with different numbers of electrical contacts and pneumatic interfaces as needed; the mounting base design allows it to be flexibly fixed on various equipment frames, making it particularly suitable for fields such as automated equipment, robots, and CNC machine tools that have high requirements for connection efficiency, reliability and cleanliness.

[0018] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1 to 8 As shown, the multifunctional connector of this invention is a three-component modular system, including a male connector 1 as a fixed interface on the device side, a female connector 2 as a movable interface on the cable side, and a connector 3 as a mounting, fixing, and locking platform.

[0024] (a) Male head 1 The male connector 1 is the part of the connector of the present invention that is fixedly installed on the equipment body, electrical cabinet or base, and is usually pre-connected to the wiring and pipelines inside the equipment.

[0025] The male connector 1 comprises a cylindrical portion 12. This cylindrical portion 12 is preferably made of engineering plastics (such as PBT, nylon, etc.) or metal, possessing sufficient mechanical strength and insulation properties. One end of the cylindrical portion 12 (defined as the front end, used for mating) has an annular groove with a specific cross-sectional shape machined on its inner wall, namely an annular retaining groove 121. This annular retaining groove 121 is a key structure for achieving initial mechanical engagement with the female connector 2.

[0026] Inside the cylindrical portion 12, multiple metal pins 13 are fixedly installed along its axial direction. These metal pins 13 serve as male terminals for electrical connections, and their tails are typically reliably connected to the high-voltage and low-voltage control circuits inside the equipment via welding, crimping, or wiring terminals. The material of the metal pins 13 can be selected according to the current, such as brass or phosphor bronze, and the surface can be gold-plated or silver-plated to reduce contact resistance and prevent oxidation. The distribution of the multiple metal pins 13 inside the cylindrical portion 12 can be flexibly arranged according to circuit design needs, such as in a circular or matrix arrangement. As a preferred arrangement that optimizes space utilization, these metal pins 13 can be arranged in a symmetrical, asymmetrical, or regional manner to integrate a larger number of contacts, and different contact functions (such as power, ground, signal A, signal B, etc.) can be defined by their different positions, thus preventing mis-insertion.

[0027] On the outer wall of the cylindrical portion 12, near its front end, at least one connecting lug 122 is integrally formed or fixedly connected. Preferably, two connecting lugs 122 are symmetrically arranged. Each connecting lug 122 has a through hole, the axis of which is approximately perpendicular to the axis of the cylindrical portion 12. The function of the connecting lugs 122 is to cooperate with the subsequent locking mechanism to achieve two-stage locking.

[0028] At the tail end of the cylindrical portion 12 (the end furthest from the slot 121), a frustum portion 11 can be further connected. The frustum portion 11 is shaped like a truncated cone and has two main functions: first, it serves as a structural transition, making the overall shape of the male head 1 more ergonomic and easier to grip or guide; second, it can have reserved space or designed interfaces for the integrated installation of quick-connect fittings for pneumatic pipelines. The pneumatic quick-connect fitting can be embedded or fixed in the inner cavity of the frustum portion 11, and its air inlet is connected to the air source pipeline inside the equipment. The presence of the frustum portion 11 enables the present invention to truly achieve "electrical and pneumatic integration". If the application scenario does not require a pneumatic pipeline, the frustum portion 11 can be designed to be solid or omitted without affecting the electrical connection function.

[0029] (ii) Mother head 2 The female connector 2 is the part of the connector of the present invention that connects to the external cable bundle 5, and is a pluggable movable part.

[0030] The main body of the female connector 2 is also typically made of insulating material. One end is designed as a protrusion 22 for mating with the male connector 1. The shape of this protrusion 22 matches the inner cavity shape of the cylindrical portion 12 of the male connector 1, allowing it to be inserted. This provides the first layer of mechanical locking force for the connection, preventing the male connector 1 and the female connector 2 from accidentally disengaging due to their own weight or slight external forces.

[0031] Inside the protrusion 22, a precisely matched metal socket 23 is embedded, corresponding to the position and arrangement of the metal pins 13 of the male connector 1. The metal socket 23 is typically a sleeve-shaped elastic element, with its inner diameter slightly smaller than the outer diameter of the metal pins 13, to ensure a tight interference fit and good electrical contact after insertion. The tail of the metal socket 23 is connected to the terminal block inside the cable interface 21 at the other end of the female connector 2 via a wire.

[0032] Furthermore, a shielding isolation element made of magnetic material is provided at the inner center of the protrusion 22. (See also...) Figure 7 The shielding isolator has a Y-shaped three-pronged structure, with its three branches extending to connect to the inner wall of the protrusion 22. This Y-shaped shielding isolator has a dual function: firstly, its magnetism can attract ferromagnetic particles that may escape from the gas path and physically block the flow of condensate, thus shielding the internal precision electrical components from the influence of condensate; secondly, located between high-voltage and low-voltage lines, it can effectively absorb high-frequency electromagnetic noise, achieving electromagnetic isolation between high-voltage and low-voltage lines, avoiding mutual interference, and improving the reliability of the connector in complex electromagnetic environments.

[0033] The other end of the female connector 2 is the cable interface section 21. The cable interface section 21 is the convergence point for the external cables 5. Its structure can be designed as a multi-port interface, such as having multiple independent cable glands or aviation socket cores with threaded locking mechanisms, each corresponding to an independent conductor (power line or signal line). These conductors are reliably connected to the tail of the corresponding metal socket 23 inside the female connector 2 by soldering, crimping, or terminal blocks. Soldering processes (such as tin soldering) ensure permanent connections and low resistance, effectively avoiding poor contact caused by loose screws due to vibration. The cable interface section 21 can also integrate a pneumatic interface for connecting external pneumatic lines. This design allows all external cables and pneumatic lines to ultimately converge and be secured to the female connector 2, forming a standard, integrated cable bundle module.

[0034] On the outer shell of the cable interface section 21, at least one (preferably two, corresponding to the male connector 1) connecting lug 122 is integrally formed or fixedly provided. The connecting lug 122 is also provided with a through hole, and its position is designed so that when the male connector 1 and the female connector 2 are fully engaged, it can be aligned with the connecting lug 122 on the male connector 1 and the hole on the fixing piece 33 on the connector 3.

[0035] (iii) Connector 3 The connector 3 is an important carrier for the mounting base and locking mechanism of the entire connector. Its core functions are threefold: fixing the male head 1, providing guidance and limiting for the insertion of the female head 2, and supporting the secondary locking mechanism.

[0036] The connector 3 has an overall L-shaped structure and can be formed by bending metal sheet or by casting high-strength plastic / metal to ensure sufficient structural strength. The L-shaped structure includes mutually perpendicular vertical and horizontal sections.

[0037] The horizontal portion forms the mounting base 32. The mounting base 32 has at least one mounting hole 321, typically a strip hole or a round hole, to facilitate the secure mounting of the entire connector 3 to the side panel, mounting beam, or any predetermined mounting position of the equipment cabinet using fasteners such as screws and bolts. The mounting base 32 provides a stable connection between the entire connector and the equipment body.

[0038] The vertical portion extends upward perpendicularly to the mounting base 32 (or depending on the mounting direction). A slot 31 is provided at the center or corresponding position of the vertical portion. The shape and size of this slot 31 match the cross-sectional shape of the protrusion 22 of the female connector 2, but its size is slightly larger to ensure that the protrusion 22 can pass smoothly through, while also providing initial lateral restraint on the insertion position of the female connector 2. The presence of the slot 31 allows the connector 3 to "enclose" the rear region of the cylindrical portion 12 of the male connector 1.

[0039] On the outer side of the vertical portion (i.e., the side facing away from the cylindrical portion 12 of the male connector 1), a fixing plate 33 is fixedly installed or integrally formed. The number and position of the fixing plates 33 correspond to the connecting lugs 122 on the male connector 1 and the female connector 2. The fixing plate 33 is provided with a through hole or a threaded hole. In a preferred embodiment, the fixing plate 33 is provided with a smooth hole for the locking bolt 4 to pass through. The function of the fixing plate 33 is to serve as a load-bearing component in the secondary locking mechanism, forming a "sandwich" structure together with the connecting lugs 122 on both sides.

[0040] (iv) Secondary locking mechanism The secondary locking mechanism is composed of connecting lugs 122 on male head 1 and female head 2, fixing piece 33 on connecting seat 3, and locking bolt 4.

[0041] After the male connector 1 and female connector 2 are initially engaged through the slot 121 and the protrusion 22, the connecting lug 122 on the male connector 1, the fixing piece 33 on the connecting seat 3, and the connecting lug 122 on the female connector 2 will be basically aligned, forming a through passage. At this time, a locking bolt 4 (usually equipped with a washer and nut) is passed sequentially through the through hole of the connecting lug 122 on the male connector 1, the through hole of the fixing piece 33, and the through hole of the connecting lug 122 on the female connector 2. The axial direction of the locking bolt 4 is designed to be approximately perpendicular to the insertion direction of the protrusion 22 on the female connector 2 (i.e., the axial direction of the cylindrical part 12 of the male connector 1).

[0042] When the nut of the locking bolt 4 is tightened, the tightening force of the bolt presses the connecting lugs 122 of the male connector 1 and the female connector 2 against the fixing plate 33 in the middle. Since the fixing plate 33 is rigidly fixed to the connector 3, and the connector 3 is fixed to the equipment by the mounting base 32, this tightening force is ultimately transformed into a strong lateral constraint force, tightly "clamping" the male connector 1, the connector 3, and the female connector 2 together to form a rigid whole. This lateral constraint force directly resists the possible axial separation tendency between the male connector 1 and the female connector 2, and forms a double spatial locking with the axial snap-fit, greatly enhancing the connector's resistance to separation under dynamic loads such as vibration and impact, and ensuring the long-term stability of the electrical connection.

[0043] I. Complete Workflow and Principles Step 1: Pre-installation on the equipment side.

[0044] First, arrange all the high-voltage wires, low-voltage signal lines, and pneumatic pipes that need to be led out from inside the equipment according to the design requirements. Reliably connect (by soldering or crimping) the tail of the metal pin 13 of the male connector 1 to the corresponding high-voltage and low-voltage wires. If a pneumatic function is configured, install the pneumatic quick-connect fitting into the frustum portion 11 and connect it to the equipment's pneumatic supply pipe. Then, pass the cylindrical portion 12 of the male connector 1 through the rear of the vertical portion of the connector 3, so that the front of the cylindrical portion 12 protrudes in front of the slot 31, while the frustum portion 11 of the male connector 1 is located behind the connector 3. At this point, the connecting lug 122 on the male connector 1 is approximately aligned with the fixing piece 33 on the connector 3. Next, secure the entire connector 3 (along with the male connector 1 that has already been passed through) to the predetermined installation position in the equipment cabinet by passing screws through the mounting holes 321 on the mounting base 32 of the connector 3. The equipment installation is now complete.

[0045] Step 2: Pre-assembly of the cable side.

[0046] Signal cables, power cables, and air hoses from external devices or power sources are bundled into external cable 5. Each individual wire in cable 5 is inserted into its corresponding individual port on the cable interface section 21 of the female connector 2. Then, inside the female connector 2, these wires are reliably connected to the tail of the corresponding metal jack 23 by soldering. The soldering process ensures extremely low contact resistance and a permanent connection, eliminating the possibility of loosening. This step can be performed in a workshop or laboratory environment, which is environmentally friendly, efficient, and ensures controllable quality.

[0047] Step 3: On-site rapid connection and primary card connection.

[0048] When connecting external devices to the main unit, the operator holds the female connector 2 with all cables integrated. The protrusion 22 of the female connector 2 is aligned with the slot 31 on the connector 3 and the inlet of the cylindrical portion 12 of the male connector 1 located in front of it. The female connector 2 is pushed axially (i.e., along the axis of the cylindrical portion 12 of the male connector 1). When the protrusion 22 is fully inserted, a clear "click" sound is usually heard, providing tactile and audible feedback to the operator, indicating that the first-stage mechanical connection is complete. Simultaneously, during insertion, the multiple metal pins 13 on the male connector 1 are also inserted synchronously and accurately into the corresponding metal sockets 23 on the female connector 2, ensuring reliable continuity of all electrical circuits. If a pneumatic circuit is integrated, the corresponding quick-connect pneumatic connector also completes the mating seal at this time. This step achieves "one-plug-and-connect, all connected," making the operation extremely quick and simple.

[0049] Step 4: Tighten the secondary bolts.

[0050] After the first-stage snap-fit ​​is completed, the male connector 1, female connector 2, and connecting seat 3 are in a state of initial fixation but not yet fully locked. To cope with potential strong vibrations, final reinforcement is required. The operator can observe that the connecting lug 122 on the male connector 1, the fixing plate 33 on the connecting seat 3, and the through hole on the connecting lug 122 on the female connector 2 are aligned. Take a pre-prepared locking bolt 4 (which can be equipped with a spring washer and a flat washer) and pass it sequentially through the through hole of the connecting lug 122 on the male connector 1, the through hole of the fixing plate 33, and the through hole of the connecting lug 122 on the female connector 1 from one side (e.g., from the male connector side). Then screw a nut onto the other end of the bolt and tighten it using a tool (such as a wrench). During tightening, the tightening force generated by the bolt presses the connecting lugs 122 of the male connector 1 and the female connector 2 tightly against the fixing plate 33 in the middle. Since the retaining plate 33 is fixed to the robust equipment cabinet via the connector 3, this fastening force is transformed into a strong lateral locking force perpendicular to the insertion and removal direction, firmly "clamping" the male connector 1 and the female connector 2 onto the connector 3, completely eliminating any possibility of slight displacement or loosening in the axial direction. At this point, the connector enters a fully locked and reliable working state.

[0051] Step 5: Disassembly process.

[0052] When disconnection is required for equipment maintenance or relocation, the disassembly process is the reverse of the installation process. First, use a tool to loosen and remove the locking bolt 4 to release the secondary locking. Then, typically pull the male connector 1 outwards; as it is pulled out, the metal pin 13 separates from the metal socket 23. The female connector 2, along with the entire external cable bundle 5, can then be separated from the equipment body. The entire process is equally quick and simple, and avoids repeated plugging and unplugging wear on the individual electrical connectors.

[0053] II. Technological Advantages 1. Modularization and Integration: The male connector 1, female connector 2, and connector 3 have clearly defined functions and independent structures, facilitating mass production and maintenance / replacement. Integrated design is the core of improving efficiency.

[0054] 2. Dual locking mechanism: The snap-fit ​​between male connector 1 and female connector 2 provides quick connection / disconnection and initial retention; the "bolt tightening" provides final vibration protection. The combination of these two mechanisms achieves an optimal balance between convenience and reliability.

[0055] 3. Welded connection ensures electrical reliability: The wires are connected to the metal socket 23 by welding inside the female connector 2. This is a key process detail to avoid loose wiring in the field and ensure long-term stable signal and power transmission.

[0056] 4. The core function of the connector: The connector 3 is not only a mounting plate, but also the force-bearing platform and docking guide mechanism of the entire locking mechanism. It disperses the axial force and vibration impact force generated during docking to the equipment cabinet through the mounting base plate 32, protecting the connection point between the male connector 1 and the equipment body.

[0057] 5. Scalability: The basic principle of this invention can be applied to various modified designs with different numbers of pins, different current levels, and whether or not a pneumatic path is included, forming a product series.

[0058] The technical solution in the above-described embodiments of this application, by setting a male connector 1 integrating a metal pin 13 and an annular slot 121, a female connector 2 integrating a metal socket 23 and a protrusion 22, and a connector 3 with a slot 31 and a mounting base 32, and cooperating with a two-stage locking mechanism consisting of a connecting lug 122, a fixing piece 33, and a locking bolt 4, achieves a highly integrated and reliable multi-functional connector. Its advantages are: integrating the high-voltage, low-voltage, and pneumatic interfaces required by the equipment into one unit, achieving "one-time plug-in, all connections," greatly simplifying on-site construction wiring, shortening the installation and commissioning cycle, and reducing wiring error rates and reliance on professional personnel; the dual fixing method of snap-fit ​​and bolt locking effectively prevents the connector from loosening under vibration, ensuring long-term stability of the electrical connection; at the same time, the centralized arrangement of the wiring harness makes the equipment neat and aesthetically pleasing inside and out, facilitating subsequent troubleshooting and maintenance, thereby significantly improving the deployment efficiency, operational reliability, and maintainability of automated equipment.
