[0001] This utility model relates to the technical field of pipeline connection components, and in particular to a metal composite low-evaporation female connector. Background Technology

[0002] In numerous industrial production, scientific research experiments, and special environmental applications, there are strict requirements for the evaporation control of transport media. For example, in semiconductor manufacturing, excessive evaporation of media such as photoresist and electronic gases can seriously affect the production precision and quality of chips. In the aerospace field, the evaporation of some special propellants or working fluids can change system parameters such as pressure and flow rate, threatening the safe operation of aircraft. In high-end laboratory environments, the evaporation of chemical reagents used for high-precision analysis and testing can interfere with the accuracy of experimental results.

[0003] Traditional female connectors have many shortcomings when dealing with environments with high requirements for media evaporation. Common all-plastic connectors are low in cost and easy to process, but plastic materials themselves have a certain degree of air permeability, and the media can easily evaporate through the plastic shell. Although some metal connectors can effectively prevent evaporation, metal materials are heavy, and they may undergo chemical reactions when in contact with some special media, affecting the purity and performance of the media.

[0004] To address this, a metal composite low-evaporation female connector is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a metal composite low-evaporation female connector, which can solve the many shortcomings of existing traditional female connectors in dealing with environments with high requirements for media evaporation. Common all-plastic connectors, although low in cost and easy to process, have a certain degree of air permeability, and the media can easily evaporate through the plastic shell. Although some metal connectors can effectively prevent evaporation, the metal material is heavy and may undergo chemical reactions when in contact with some special media, affecting the purity and performance of the media.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal composite low-evaporation female connector, comprising a connector body, wherein the rear end of the connector body is made of metal material, the front end of the connector body is made of plastic material, the connector body is manufactured by an integral injection molding process, and anti-slip ribs are provided on the outer side of the front end of the connector body.

[0007] Preferably, the front end of the connector body is provided with reinforcing ribs, which are distributed in a cross shape.

[0008] Preferably, the rear end of the connector body is made of stainless steel, which has good corrosion resistance and low air permeability.

[0009] Preferably, the anti-slip rib is in the form of a circular ring and is made of thermoplastic elastomer material.

[0014] Preferably, a locking spring is provided on the rear side inside the connector body, and the outer side of the locking spring penetrates the interior of the connector body.

[0015] Preferably, a marking area is provided on the rear side of the surface of the connector body, and the marking area is made by laser engraving.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This application sets up a connector body with a metal rear end and a plastic front end, which are integrally injection molded. The metal material has low air permeability, which can effectively block the evaporation of the medium and avoid the phenomenon of evaporation caused by the medium passing through the plastic shell, as in traditional all-plastic connectors. At the same time, the use of plastic material at the front end reduces the overall weight of the connector body while ensuring basic functions, overcoming the problem of excessive weight in some metal connectors. Moreover, the integral injection molding process makes the connector body structure more stable, reduces the risk of medium leakage caused by gaps that may be caused by splicing different materials, and improves the reliability and durability of the connector body.

[0018] 2.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] A metal composite low-evaporation female connector includes a connector body 1. The rear end of the connector body 1 is made of metal material, and the front end of the connector body 1 is made of plastic material. The connector body 1 is manufactured by one-piece injection molding process, and anti-slip ribs 2 are provided on the outer side of the front end of the connector body 1.

[0028] In this embodiment: by setting the connector body 1 and anti-slip ribs 2, the connector body 1 adopts a structural design of integral injection molding of rear metal material and front plastic material. The metal material has low air permeability, which is like setting up a strong barrier for the medium, effectively preventing the medium from evaporating outward from the rear end of the connector body 1, avoiding the medium evaporation problem caused by the air permeability of the plastic shell in traditional all-plastic connector bodies 1. The front plastic material reduces the overall weight of the connector body 1, and while meeting the basic function of adapting and connecting the connector body 1 with other components, it also has good processing performance and insulation performance. The integral injection molding process makes the connector body 1 a tightly integrated whole, eliminating... In addition to preventing gaps that may appear at the joints of different materials, ensuring stable and reliable operation of the connector body 1 under various working conditions, the anti-slip rib 2 is set on the outer front end of the connector body 1. Its working principle is based on the increase of friction. When the hose is sleeved on the front end of the connector body 1, the anti-slip rib 2 is in close contact with the inner wall of the hose. When subjected to external forces such as vibration and pressure changes, the anti-slip rib 2 increases the friction between the hose and the hose by increasing the roughness of the contact surface. This makes the hose and the front end of the connector body 1 tightly connected, preventing the hose from falling off even in complex working environments, ensuring the stability of the pipeline connection, and ensuring that the medium can be safely and smoothly transported in the pipeline.

[0029] Specifically, such as Figure 3 As shown, a reinforcing rib 3 is provided at the front end of the interior of the connector body 1, and the reinforcing rib 3 is distributed in a cross shape.

[0030] Specifically, such as Figure 1 , Figure 2 As shown, the rear end of the connector body 1 is made of stainless steel, which has good corrosion resistance and low air permeability.

[0031] Specifically, such as Figure 1 , Figure 2 As shown, the anti-slip rib 2 is in the shape of a circular ring and is made of thermoplastic elastomer material.

[0032] In this embodiment: by setting reinforcing ribs 3, which are distributed in a cross shape at the front end of the connector body 1, the structural strength of the plastic at the front end of the connector body 1 is indirectly enhanced, stress is dispersed and deformation is prevented, and the stainless steel connector body 1 at the rear end is corrosion resistant and has low air permeability, ensuring the stability of the connector body 1 in complex environments and preventing the medium from evaporating. At the same time, the circular anti-slip ribs 2 of thermoplastic elastomer can evenly fit the tube, and the elastic deformation increases friction, making it wear-resistant and with stable anti-slip performance.

[0033] Specifically, such as Figure 3As shown, an annular sealing ring 4 is provided at the transition between the metal part near the tail end and the plastic part at the front end inside the connector body 1. The annular sealing ring 4 is made of rubber material.

[0034] Specifically, such as Figure 1 , Figure 2 As shown, the height of the anti-slip rib 2 is 2-3 mm, and the width of the anti-slip rib 2 is 2-2.5 mm.

[0035] In this embodiment: By setting an annular sealing ring 4, the annular sealing ring 4, located near the transition between the tail end metal part and the front end plastic part inside the connector body 1, is made of rubber material. Rubber has good elasticity and sealing performance. After the connector body 1 is installed, the annular sealing ring 4 will be compressed to a certain extent, thereby tightly filling the transition gap between the metal and plastic. This sealing ring acts like a tight barrier, effectively preventing the medium from leaking from the transition point inside the connector body 1. In addition, the anti-slip rib 2 is designed with a height of 2-3 mm and a width of 2-2.5 mm, which can ensure connection stability while taking into account the convenience and adaptability of hose installation. When connected with the hose, this height allows the anti-slip rib 2 to be embedded in the inner wall of the hose just right, forming a tight mechanical engagement.

[0036] Specifically, such as Figure 2 As shown, the thickness of the reinforcing rib 3 is 2-3 mm, and the width of the reinforcing rib 3 is 1-2 mm.

[0037] Specifically, such as Figure 1 , Figure 2 As shown, the surface of the anti-slip rib 2 is provided with anti-slip texture, which is in the shape of lines.

[0038] In this embodiment: The 2-3 mm thick reinforcing rib 3 enhances the structural strength of the plastic at the front end of the connector body 1, effectively dispersing the stress caused by external forces, preventing the plastic from deforming and cracking due to stress concentration, and ensuring the stable connection of the connector body 1. At the same time, the 1-2 mm width ensures the reinforcement effect while taking into account material cost and weight, achieving a balance between performance and cost. In addition, the linear anti-slip texture on the surface of the anti-slip rib 2 increases the contact roughness with the inner wall of the hose, which not only indirectly increases the contact area to improve friction, but also guides the flow of the medium, avoiding the hose from sliding due to uneven medium pressure, ensuring a tight connection between the hose and the connector body 1 in complex environments, and preventing detachment.

[0039] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, a locking spring 5 is provided on the rear side inside the connector body 1, and the outer side of the locking spring 5 penetrates the interior of the connector body 1.

[0040] Specifically, such as Figure 1 , Figure 2As shown, a marking area 6 is provided on the rear side of the surface of the connector body 1. The marking area 6 is made using laser engraving technology.

[0041] In this embodiment: a locking spring 5 is provided on the rear side of the inside of the connector body 1, and its outer side penetrates the inside of the body. When connected with other components, such as the corresponding male connector, the locking spring 5 can be inserted into a specific slot to form a mechanical locking structure. This not only enhances the connection firmness, but also resists complex working conditions such as vibration and pressure fluctuations, effectively preventing the connector body 1 from being accidentally separated, greatly improving the reliability and safety of the pipeline system, and ensuring connection stability even after long-term use. In addition, the marking area 6 on the rear side of the surface of the connector body 1 is made by laser engraving, which makes the marking clear, durable, and not easy to wear and fade. At the same time, the marking area 6 can be set with key information such as model, specifications, and applicable media, providing convenience for users.

[0042] Working Principle: In the use of the metal composite low-evaporation female connector, its main body 1 is integrally injection molded with metal at the rear end and plastic at the front end. The low permeability and corrosion resistance of the metal prevent media evaporation and corrosion at the rear end, while the plastic reduces weight and provides good processing and insulation properties. The integral injection molding eliminates splicing gaps, ensuring overall sealing and stability. The anti-slip rib 2 located on the outer surface of the main body 1 is circular and made of thermoplastic elastomer material, 2-3 mm high and 2-2.5 mm wide, with linear anti-slip textures on the surface. When the hose is connected, the anti-slip rib 2 fits tightly against the inner wall of the hose. The elastic deformation of the elastomer, the increased roughness of the texture, and the appropriate size work together to increase friction. The friction prevents the hose from detaching under external forces such as vibration and pressure changes. The front end of the connector body 1 features cross-shaped reinforcing ribs 3, 2-3 mm thick and 1-2 mm wide, which enhance the strength of the plastic structure, disperse external stress, and prevent front-end deformation and breakage. The internal rubber annular sealing ring 4 fills the gap under pressure, preventing media leakage. Simultaneously, the internal rear locking spring 5 can be engaged with male connectors and other components to form a mechanical lock, resisting complex working conditions and preventing accidental connector separation. The laser-engraved marking area 6 on the rear surface is clear and durable, containing information such as model, specifications, and applicable media, allowing users to quickly obtain key parameters and improve installation and maintenance efficiency.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
