Description

Technical Field

[0001] This invention belongs to the field of connector technology, specifically relating to connectors that can achieve foolproof design and information traceability. Background Technology

[0002] Chinese invention patent CN222637827U discloses a foolproof connector, including a female end assembly and a male end assembly that are directly interlocked. The female end assembly has a female end housing with one open end, and a female end connector fixed at the opening is connected inside the female end housing. The female end connector has a groove on its outward-facing side. The male end assembly has a male end housing with one open end, and a male end connector fixed at the opening is connected inside the male end housing. The male end connector has a protrusion on its outward-facing side that inserts into the groove. The female end connector also has at least two foolproof slots of different sizes that communicate with the groove on its outward-facing side. The inner diameter of the foolproof slots gradually increases towards the open end, and at least two foolproof parts that match the insertion of the protrusion into the foolproof slot are connected to the outside of the protrusion. By adding foolproof parts and foolproof slots at the connection point, and by using a structure where the smaller outer diameter end is inserted first, the foolproof part achieves a good foolproof effect and can also automatically correct itself.

[0003] Existing quick-connect connectors lack a unique information identification structure and an assembly status confirmation structure. Summary of the Invention

[0004] The purpose of this invention is to provide a connector that enables error prevention and information traceability, which can solve the problem of existing quick-connect connectors lacking a unique information identification structure and an assembly status confirmation structure.

[0005] To achieve the above objectives, a specific embodiment of the present invention provides the following technical solution: A connector capable of error prevention and information traceability includes: a QC housing, a first sealing ring, a locking device, a second sealing ring, a guide top ring, a digital verification card, and a male plug; the QC housing forms an axially extending receiving cavity, and the first sealing ring, locking device, second sealing ring, guide top ring, digital verification card, and male plug are sequentially assembled along the axial direction of the receiving cavity; the male plug can move axially along the receiving cavity and partially extend into the QC housing, the locking device is clamped between the QC housing and the male plug, and the digital verification card is located between the guide top ring and the male plug.

[0006] In one or more embodiments of the present invention, the first sealing ring and the second sealing ring are both annular elastic elements. The first sealing ring is embedded in the inner side of the port of the QC housing cavity, and the second sealing ring is embedded in the annular groove in the middle of the cavity.

[0007] In one or more embodiments of the present invention, the locking device is integrally bent from spring steel wire, and the locking device has elastic deformation portions distributed circumferentially, the inner surface of the elastic deformation portions being in contact with the outer peripheral surface of the male plug.

[0017] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0018] like Figures 1 to 2 As shown, this application provides a connector capable of error prevention and information traceability, including: a QC housing 1, a first sealing ring 2, a locking device 3, a second sealing ring 4, a guide top ring 5, a digital verification card 6, and a male plug 7; an axially extending receiving cavity is formed inside the QC housing 1, and the first sealing ring 2, the locking device 3, the second sealing ring 4, the guide top ring 5, the digital verification card 6, and the male plug 7 are sequentially assembled along the axial direction of the receiving cavity; the male plug 7 can move along the axial direction of the receiving cavity and partially extend into the QC housing 1, the locking device 3 is clamped between the QC housing 1 and the male plug 7, and the digital verification card 6 is located between the guide top ring 5 and the male plug 7.

[0019] In this embodiment, the modular structure design with axial sequential assembly enables precise positioning and collaborative work of each component. The positional layout of the locking device 3 and the digital verification card 6 not only ensures connection stability but also provides a structural basis for error-proof verification and information traceability. At the same time, it facilitates assembly and subsequent maintenance, thereby improving the overall reliability and versatility of the connector.

[0020] The first sealing ring 2 and the second sealing ring 4 are both annular elastic elements. The first sealing ring 2 is embedded inside the port of the receiving cavity of the QC housing 1, and the second sealing ring 4 is embedded in the annular groove in the middle of the receiving cavity.

[0021] In this embodiment, the axial partitioning of the double sealing rings forms a double sealing protection structure. The first sealing ring 2 can block external dust and moisture from entering the cavity from the port. The second sealing ring 4 further seals the central area to prevent internal parts from being corroded by the environment. At the same time, it enhances the fit and sealing of the male plug 7 after it is connected to the QC housing 1, prevents fluid or gas leakage, and improves the connector's applicability in harsh environments.

[0022] The locking device 3 is integrally bent from spring steel wire. The locking device 3 has elastic deformation parts distributed circumferentially, and the inner surface of the elastic deformation parts is in contact with the outer peripheral surface of the male plug 7.

[0023] In this embodiment, the integrally formed spring steel wire structure design ensures the structural strength and elastic deformation stability of the locking device 3. The circumferentially distributed elastic deformation part achieves elastic locking after the male plug 7 is inserted by tightly fitting with the outer peripheral surface of the male plug 7. This not only prevents the male plug 7 from accidentally falling off during the connection process, but also adapts to the insertion and removal actions of the male plug 7 through elastic deformation. At the same time, the close-fitting contact can limit the radial wobbling of the male plug 7, improve the connection accuracy, and indirectly assist in the realization of the foolproof function.

[0024] The guide top ring 5 is an annular structure. The inner hole of the guide top ring 5 is clearance-fitted with the outer peripheral surface of the male plug 7. One axial end of the guide top ring 5 abuts against the second sealing ring 4, and the other end abuts against the digital verification card 6.

[0025] In this embodiment, the guide top ring 5 of the annular structure provides precise guidance for the axial movement of the male plug 7 through the gap fit between the inner hole and the male plug 7, avoiding assembly errors such as skewing and jamming during insertion, and realizing foolproof assembly; at the same time, the two ends of the axial structure abut against the second sealing ring 4 and the digital verification card 6 respectively, which not only limits the second sealing ring 4 axially to prevent it from shifting and affecting the sealing effect, but also presses the digital verification card 6 to ensure its positional stability, providing a reliable guarantee for subsequent information reading.

[0026] A through observation hole 8 is provided on the side wall of the QC housing 1. The observation hole 8 is arranged radially along the QC housing 1, and the radial dimension of the digital verification card 6 is adapted to the aperture of the observation hole 8.

[0027] In this embodiment, the radially arranged observation hole 8 is designed to be size-compatible with the digital verification card 6, allowing operators to directly read the information on the digital verification card 6 through the observation hole 8 without disassembling the connector, thus enabling rapid information traceability. At the same time, the position design of the observation hole 8 can intuitively confirm the installation status of the digital verification card 6, avoiding the failure of the traceability function due to missing or displaced cards. In conjunction with the foolproof markings on the digital verification card 6, it can also help determine whether the male plug 7 is properly assembled.

[0028] The outer peripheral surface of the male plug 7 is provided with an anti-rotation protrusion 9. The anti-rotation protrusion 9 is an annular protrusion extending circumferentially along the male plug 7. The end face of the anti-rotation protrusion 9 can fit and abut against the end face of the digital verification card 6.

[0029] In this embodiment, the annular protrusion anti-rotation boss 9 abuts against the end face of the digital verification card 6, thereby achieving precise limiting of the insertion stroke of the male plug 7, preventing excessive or incomplete insertion, and directly achieving a mechanical anti-mistake effect to prevent connection failure due to improper assembly. On the other hand, the circumferentially extended structure can restrict the circumferential rotation of the male plug 7 within the receiving cavity, preventing damage to the internal circuitry or sealing structure due to rotation during the connection process. At the same time, it enhances the axial fit between the male plug 7 and each component, improving the overall connection stability.

[0030] One end of the QC housing 1 is provided with an assembly through hole for the male plug 7 to pass through, and the diameter of the assembly through hole is adapted to the outer diameter of the male plug 7; the other end of the QC housing 1 is a bamboo joint end 10, and the outer circumferential surface of the bamboo joint end 10 is provided with multiple annular protrusions distributed axially at intervals.

[0031] In this embodiment, the matching design of the assembly through hole and the outer diameter of the male plug 7 further improves the insertion guidance accuracy, reduces assembly deviation, and assists in the foolproof function; the multi-ring protrusion structure of the bamboo joint end 10 can enhance the connection friction between the QC housing 1 and external pipelines and equipment, and prevent slippage or detachment after connection. At the same time, the ring protrusion can increase the sealing contact area, improve the sealing effect with the external structure, expand the installation scenarios of the connector, and adapt to different connection requirements.

[0032] The digital verification card 6 is a sheet-like structure with an engraving area on its outer surface, located on the side of the digital verification card 6 facing the observation hole 8.

[0033] In this embodiment, the sheet-like structure is easy to install and position. The engraved area facing the observation hole 8 can clearly display digital content such as product model, production batch, and verification information, realizing information traceability throughout the product's entire life cycle, facilitating quality control, maintenance and replacement, and accountability. At the same time, the engraved digital information can include foolproof markings (such as specific codes and shape markings). Combined with the visual inspection through the observation hole, it can quickly determine whether the connector is a compatible model, avoid mismatched installation, and enhance the foolproof effect.

[0034] There are three elastic deformation parts, which are evenly distributed around the locking device 3. Each elastic deformation part has an arc-shaped bending structure, and its free end faces the insertion direction of the male plug 7.

[0035] In this embodiment, three evenly distributed elastic deformation parts form a three-point fitting and positioning, making the force on the male plug 7 more balanced and the locking effect more stable, avoiding local wear or locking failure caused by single-point force; the arc-shaped bending structure and the free end design facing the insertion direction can guide the male plug 7 to be inserted smoothly and reduce insertion resistance. At the same time, the restoring force of elastic deformation can form a uniform locking pressure, which not only ensures the reliability of the connection, but also facilitates the disassembly of the male plug 7 and improves the convenience of operation.

[0036] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics.
