Description

Technical Field

[0001] This utility model relates to the field of waterproof connectors, and in particular to a waterproof connector in a non-mating state. Background Technology

[0002] Waterproof connectors, sometimes called watertight connectors, are mainly divided into two categories: faceplate-only and fully sealed. For fully sealed connectors, the traditional design uses PTFE (Teflon) as the insulating medium, with special O-rings embedded between the housing and insulation, and between the center pin and insulation, to achieve waterproofing. Waterproof connectors prevent moisture ingress. They are suitable for outdoor and harsh environment applications, including wireless telecommunications antennas, radio equipment, tactical radios, and outdoor sensors.

[0003] Traditional coaxial waterproof connectors require additional slots for installing O-rings, leading to complex component structures, increased manufacturing costs, and a greater overall design complexity. The time and cost of assembling the components also increase, and combined with the cost of the O-rings themselves, this results in a higher overall product cost.

[0004] Therefore, it is necessary to propose a waterproof connector for non-mating states to solve the above problems. Utility Model Content

[0005] The main objective of this invention is to provide a waterproof connector in a non-mating state, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A waterproof connector in a non-mating state includes a connector body, a center conductor installed in the inner cavity of the connector body, a PEI insulator installed on the left side of the outer wall of the center conductor, a first anti-deformation component sleeved on the outer wall of the center conductor, auxiliary components symmetrically installed around the right side of the first anti-deformation component, and a second anti-deformation component symmetrically installed around the right side of the inner cavity of the connector body.

[0008] Preferably, the PEI insulator is made of polyetherimide material, the left side of the first anti-deformation component is attached to the right side of the PEI insulator, the connector body has symmetrically formed movable grooves around its inner cavity, the center conductor is interference-fitted with the PEI insulator, and the PEI insulator is interference-fitted with the connector body.

[0009] Preferably, movable blocks are symmetrically installed around the outer wall of the first anti-deformation component. The movable blocks are movably connected to the inner cavity of the movable groove. A guide rod is installed in the inner cavity of the movable groove, and a first compression spring is wound around the outer wall of the guide rod.

[0010] Preferably, the left side of the first compression spring is connected to the right side of the movable block, the right side of the first compression spring is installed on the right side of the inner cavity of the movable groove, and the first anti-deformation component is movably connected in the inner cavity of the connector body.

[0011] Preferably, the other end of the auxiliary component is rotatably connected to a bonding wheel, which is bonded to the outer wall of the central conductor. A connecting post is installed on the right side of the auxiliary component, and a limiting block is installed on the right side of the connecting post. The limiting block is movably connected in the inner cavity of the second anti-deformation component, which is sleeved on the outer wall of the connecting post.

[0012] Preferably, a fixing rod is installed in the inner cavity of the second anti-deformation component, and a second compression spring is wound around the outer wall of the fixing rod. The right side of the second compression spring is installed on the right side of the inner cavity of the second anti-deformation component, and the left side of the second compression spring is installed on the right side of the limiting block. The connecting column and the limiting block are both sleeved on the outer wall of the fixing rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This waterproof connector in its non-mating state uses polyetherimide (PEI), a super engineering plastic made from amorphous PEI. PEI is characterized by high strength, high rigidity, wear resistance, and dimensional stability at high temperatures, as well as chemical resistance, flame retardancy, electrical properties, high strength, and high rigidity. PEI possesses excellent mechanical strength, electrical insulation properties, radiation resistance, high and low temperature resistance, fatigue resistance, and moldability. PEI exhibits outstanding electrical properties (stable dielectric constant and dielectric loss over a wide frequency and temperature range, and extremely high dielectric strength). PEI also has a wide range of chemical resistance, including resistance to most hydrocarbons, alcohols, and all halogenated solvents. Polyetherimide (PEI) is a good choice for resistance to inorganic acids and short-term resistance to weak alkalis, as well as some halogenated solvents. It exhibits excellent hydrolytic stability, retaining over 85% of its tensile strength after immersion in boiling water for 10,000 hours, and maintaining 100% tensile strength after 2,000 steam hot-pressing cycles at 270°F. Based on these characteristics, PEI is selected as the insulation material. The PEI insulator is interference-fitted with both the center conductor and the connector body, achieving interface waterproofing. Compared to traditional watertight connectors, using PEI as insulation simplifies the structure, eliminates the need for O-rings in traditional designs, and only requires interference fits between components.

[0015] 2. In the non-mating state, the waterproof connector, through the first compression spring, can continuously push the first anti-deformation component to the left via the movable block, so that the first anti-deformation component can support the right side of the PEI insulator, which can strengthen and prevent deformation. In conjunction with the second compression spring, the first anti-deformation component can be strengthened by the connecting post and auxiliary components, thereby further improving the support effect on the PEI insulator.

[0023] Polyetherimide (PEI) is a super engineering plastic made from amorphous polyetherimide. PEI is characterized by high strength, high rigidity, abrasion resistance, and dimensional stability at high temperatures, as well as chemical resistance, flame retardancy, electrical properties, and high strength and rigidity. PEI possesses excellent mechanical strength, electrical insulation properties, radiation resistance, high and low temperature resistance, fatigue resistance, and moldability. PEI exhibits outstanding electrical properties (stable dielectric constant and dielectric loss over a wide frequency and temperature range, and extremely high dielectric strength). PEI also has a wide range of chemical resistance, including resistance to most hydrocarbons, alcohols, and all halogenated solvents; it is also resistant to inorganic acids and short-term resistance to weak acids. For alkalis and partially halogenated solvents, polyetherimide (PEI) is a good choice. It has excellent hydrolytic stability, retaining more than 85% of its tensile strength after immersion in boiling water for 10,000 hours, and maintaining 100% of its tensile strength after 2,000 steam hot-pressing cycles at 270°F. Based on these characteristics, PEI is selected as the insulation material. The PEI insulator 3 is interference-fitted with the center conductor 2 and the connector body 1, achieving the purpose of interface waterproofing.
