Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a circular connector with a two-dimensional code mark and an in-place identification structure. Background Art

[0002] With the advancement of information management in various industries, more and more products require the printing of unique QR code labels that store identification code information on the surface of the product, and enter the management system to facilitate product information tracing, so that when there is a problem with the product, the corresponding product information can be obtained in a timely and accurate manner. At present, the shell surface of circular connectors is an arc structure, which is difficult to mark, but there is no large enough plane for marking QR codes, so the marking position of the QR code becomes a problem.

[0003] In addition, the threaded circular connectors currently widely used in the market all rely on visual inspection to determine whether the product is properly connected. When the plug and the socket are connected, the plug is visually observed to cover the socket color ring to determine whether it is properly connected. However, when the product installation space is small and the visual conditions are poor, it is impossible to accurately determine whether the product is properly connected by visual methods. Moreover, this method relies on naked eye identification, which is prone to over-tightening or under-tightening, affecting the connection effect and causing the waterproof function of the sealing ring to fail. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a circular connector with a QR code identification and an in-place identification structure. A QR code identification structure is designed on the connector shell to realize laser printing of QR code, ID identification, model and other product information on the shell. A positioning step is designed on the socket shell, and the socket can be tightened to the positioning step. The positioning method is simple and accurate, which solves the problem of marking information such as QR code, ID identification, model and the like, and effectively confirms whether the docking is in place.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A circular connector with a QR code identification and an in-place identification structure comprises a socket shell and a plug shell, wherein the portion of the socket shell connected to the plug shell is the socket connection end, a polygonal column step is provided below the socket connection end and is coaxial with the socket connection end, and the distance from the upper surface of the polygonal column step to the upper end surface of the socket connection end is consistent with the connection length between the socket shell and the plug shell; the portion of the plug shell connected to the socket shell is the plug connection end, and the outer wall of the plug connection end is provided with a polygonal column structure.

[0007] Preferably, the polygonal column structure on the plug housing is a column structure composed of regular hexagons, and the polygonal column step on the socket housing is a column structure composed of regular octagons.

[0008] Preferably, the polygonal column structure of the plug connection end is combined with a coaxial cylinder, and the corners are replaced by arcs of the cylinder.

[0009] Preferably, a boss is provided above the side of the polygonal step and is flush with the upper surface of the polygonal step, and a lead sealing hole coaxial with the socket housing is provided on the boss; a circular boss coaxial with the plug connection end is provided below the plug connection end, and a plurality of lead sealing holes are evenly distributed on the circular boss.

[0010] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0011] 1. The problem of being unable to print QR codes, ID logos, models and other information on the product surface is solved through the polygonal column steps on the socket housing and the polygonal column structure on the plug housing.

[0012] 2. By designing a multi-prism step on the socket housing, you only need to tighten the plug housing to the step when docking. The positioning method is simple and accurate, especially when the product installation space is small and the visual conditions are poor, and it cannot be identified by visual methods, the plug housing and the socket housing can be docked in place without visual inspection.

[0013] 3. Add lead sealing holes on the socket housing and the plug housing respectively. Once the connector is properly sealed, it cannot be opened without authorization, which makes it easy to confirm whether someone has opened the connector privately after installation.

[0014] 4. Low cost, simple process, high processing efficiency, and easy to achieve mass production. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] The utility model provides the following technical solutions:

[0021] like Figures 1 to 3 , a circular connector with a two-dimensional code identification and an in-place identification structure, comprising a socket housing 1 and a plug housing 2, wherein the socket housing 1 is divided into an upper and lower part; the part of the upper part of the socket housing 1 connected to the plug housing 2 is a socket connection end 1-1, a polygonal column step 1-2 is provided below the socket connection end 1-1, and is coaxial with the socket connection end 1-1, and the distance from the upper surface of the polygonal column step 1-2 to the upper end surface of the socket connection end 1-1 is consistent with the connection length of the socket housing 1 and the plug housing 2; the polygonal column step can effectively determine whether the plug housing is in place, and when the plug housing touches the polygonal column step, it is in place; a square flange is provided below the polygonal column step 1-2, which can be connected to the square flange of the lower part of the socket housing 1 by bolts;

[0022] The portion of the plug housing 2 connected to the socket housing 1 is a plug connection end 2-1, and the outer wall of the plug connection end 2-1 is provided with a multi-prism structure 2-2;

[0023] The polygonal column structure 2-2 on the plug housing 2 is a column structure composed of a regular hexagon and is combined with a coaxial cylinder. The corners are replaced by the arc of the cylinder, which is beautiful and reduces the material consumption; the polygonal column step 1-2 on the socket housing 1 is a column structure composed of a regular octagon. The polygonal column step 1-2 has four sides that are flush with the four sides of the square flange below it to form a large plane that can be printed with QR codes, logos, models and other product information; QR codes, logos, models and other product information can also be printed on any side of the polygonal column step 1-2 and the polygonal column structure 2-2;

[0024] A boss 1-3 is provided above the side of the polygonal column step 1-2 and is flush with the upper surface of the polygonal column step 1-2. A lead sealing hole 2-4 coaxial with the socket housing 1 is provided on the boss 1-3; a circular boss 2-3 coaxial with the plug connection end 2-1 is provided below the plug connection end 2-1, and three lead sealing holes 2-4 are evenly distributed on the circular boss 2-3. When sealing, the stainless steel wire is passed through the lead sealing hole on the socket housing, the steel wire is folded in half and twisted, and then passed through the lead sealing hole on the plug housing closest to the tightening direction, and then twisted and put on the lead block, and the lead seal is flattened with a special lead locking pliers, and the socket housing and the plug housing are locked, and finally the excess steel wire is cut off. After the lead sealing is completed, it cannot be opened without authorization, which can effectively confirm whether someone has opened the connector privately after installation.

[0025] principle:

[0026] By designing the distance between the polygonal column step 1-2 and the upper end face of the socket housing 1 to be consistent with the connection width between the socket housing 1 and the plug housing 2, the plug housing 2 only needs to be tightened to the step during docking to achieve docking. The positioning method is simple and accurate, especially when the product installation space is small and the visual conditions are poor, and it cannot be identified by visual methods, the plug housing 2 and the socket housing 1 can be docked in place without visual inspection. The multiple side planes obtained by the polygonal column step 1-2 on the socket housing 1 and the polygonal column structure 2-2 on the plug housing 2 are convenient for printing QR codes, ID logos, model numbers and other information.

[0027] Sealing holes are respectively added to the socket housing 1 and the plug housing 2 to facilitate the sealing of the socket and the plug. Once the connector is properly sealed, it cannot be opened without authorization, which can effectively confirm whether someone has opened the connector privately after installation.
