Description

Technical Field

[0001] This utility model relates to the field of wire harness connector technology, specifically to male and female connectors for wire harnesses. Background Technology

[0002] High-performance nylon wire harness connectors are crucial components in the rapid development of modern electronic technology, enabling electrical connections in electronic devices. Their performance directly affects the stability and reliability of the entire electronic system. Wire harness male and female connectors are widely used in various electronic devices, communication systems, automotive electronics, aerospace and many other fields to achieve efficient and stable signal transmission and power supply between different circuit modules.

[0003] Existing male and female connectors for wire harnesses on the market have shortcomings in several aspects. From the perspective of material selection, some connectors use ordinary metal materials for their conductive parts, which have limited conductivity. When transmitting high-frequency signals or high currents, they will generate significant resistance loss, resulting in severe signal attenuation and affecting signal integrity and accuracy. For example, some connectors use ordinary copper for their center pins. During high-frequency signal transmission, due to the skin effect, the signal is mainly concentrated on the conductor surface. The surface characteristics of ordinary copper cannot effectively reduce signal transmission loss, resulting in a decrease in signal quality. Therefore, we need to propose male and female connectors for wire harnesses. Utility Model Content

[0024] 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.

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] The wire harness male and female connector includes a female component 1 and a male component 2, which are connected to the female component 1. The male and female plug-in design allows for quick connection and disconnection, facilitating the installation, maintenance and replacement of the wire harness, while ensuring the structural stability after connection and preventing signal transmission interruption caused by loosening.

[0027] In an optional embodiment: the female end assembly 1 includes a female end housing 11, a female end zinc alloy body 15 is inserted into the female end housing 11, a female end insulator 16 is pressed into the interior of one end of the female end zinc alloy body 15, a female end center pin 13 is inserted into the interior of the other end, one end of the female end center pin 13 extends into the interior of the female end insulator 16, and a female end coaxial cable 17 is pressed into the interior of the other end.

[0028] It should be noted that the female end housing 11 provides insulation protection and structural support for internal components, preventing interference and damage from the external environment; the female end zinc alloy body 15 is made of die-cast zinc alloy, which has good shielding performance and can effectively isolate external electromagnetic interference, ensuring signal transmission quality; the female end insulator 16 is made of high dielectric constant plastic, assembling the female end center pin 13 and providing insulation between the center pin and the female end zinc alloy body 15. The press-fit installation can accurately fix the female end center pin 13, ensuring its positional stability and avoiding poor contact caused by shaking; the female end center pin 13 is crimped to the female end coaxial cable 17, and the connection is tight and firm, reducing contact resistance and ensuring efficient signal transmission.

[0029] In an optional embodiment: the male end assembly 2 includes a male plastic shell 24, a male zinc alloy 21 is inserted into the male plastic shell 24, a male insulator 22 is pressed into the interior of one end of the male zinc alloy 21, a male center pin 25 is inserted into the interior of the other end, one end of the male center pin 25 extends into the interior of the male insulator 22, and a male coaxial cable 26 is pressed into the interior of the other end, one end of the male plastic shell 24 is inserted into the interior of the female plastic shell 11, and one end of the male center pin 25 is inserted into the interior of one end of the female center pin 13.

[0030] It should be noted that the male connector's plastic shell 24 serves to insulate and protect the internal components of the male connector, and its insertion with the female connector's plastic shell 11 achieves the initial positioning and connection of the male and female connectors. The male connector's zinc alloy 21 also has excellent shielding capabilities, forming a complete shielding system with the female connector's zinc alloy body 15, further enhancing anti-interference capabilities. The male connector's insulator 22 is made of high dielectric constant plastic, assembling the male connector's center pin 25 and providing insulation between the male connector's center pin 25 and the male connector's zinc alloy 21. Press-fit installation can stably support the male connector's center pin 25, ensuring its precise connection with the female connector's center pin 13. The male connector's center pin 25 is firmly crimped with the male connector's coaxial cable 26, and the insertion of the male connector's center pin 25 with the female connector's center pin 13 enables effective signal transmission, ensuring the stability of the transmission path.

[0031] It is worth noting that the top and bottom of the male plastic shell 24 inserted into the female plastic shell 11 are both reserved with protrusions. The top protrusion is engaged with the reserved slot on the female plastic shell 11, and the bottom protrusion is engaged with the end of the female plastic shell 11.

[0032] In an optional embodiment: a female end crimping tube 14 is installed on the outer wall of one end of the female end zinc alloy body 15, and the inner wall of one end of the female end crimping tube 14 is crimped with the outer wall of one end of the female end coaxial cable 17.

[0033] It should be noted that the crimping of the female end conduit 14 with the female end zinc alloy body 15 and the outer wall of the female end coaxial cable 17 not only enhances the connection strength between the female end coaxial cable 17 and the female end zinc alloy body 15 and prevents the cable from falling off, but also reliably connects the cable's shielding layer with the zinc alloy body, improving the overall shielding effect and reducing signal leakage.

[0034] In an optional embodiment: a male crimping tube 23 is installed on the outer wall of one end of the male zinc alloy 21, and the inner wall of one end of the male crimping tube 23 is crimped to the outer wall of one end of the male coaxial cable 26.

[0035] It should be noted that the male crimp tube 23 is similar to the female crimp tube 14, which can strengthen the connection between the male coaxial cable 26 and the male zinc alloy 21, and at the same time realize the effective connection between the cable shielding layer and the male zinc alloy 21. Together with the female end structure, it forms a complete shielding circuit and improves the anti-interference performance of the connector.

[0036] In an optional embodiment: the female end crimping tube 14 is coaxially arranged with the female end center pin 13, and the male end crimping tube 23 is coaxially arranged with the male end center pin 25.

[0037] It should be noted that the coaxial cable configuration can ensure the symmetry of the connector's internal structure, reduce impedance abrupt changes during signal transmission, reduce signal reflection and loss, and ensure the integrity and stability of signal transmission, making it particularly suitable for high-frequency signal transmission scenarios.

[0038] In an optional embodiment: the outer wall of the female end shell 11 is provided with a female end buckle 12 that covers the opening of the side wall of the female end shell 11, and the outer wall of the male end shell 24 is provided with a male end buckle 27 that covers the opening of the side wall of the male end shell 24.

[0039] It should be noted that the female end buckle 12 and the male end buckle 27 respectively cover and connect the side wall openings of the female end rubber shell 11 and the male end plastic shell 24, which can enhance the structural strength of the rubber shell and the plastic shell and prevent them from deforming during insertion and removal. At the same time, the buckle structure can provide additional locking force after the male and female ends are inserted to ensure the reliability of the connection and prevent accidental detachment.

[0040] In an optional embodiment: both the female crimp tube 14 and the male crimp tube 23 are made of tin-plated brass, and both the female center pin 13 and the male center pin 25 are made of gold-plated phosphor bronze.

[0041] It should be noted that the tin-plated brass crimping tube has good electrical conductivity, thermal conductivity and corrosion resistance, which can ensure the electrical connection performance and service life of the crimped parts; the gold-plated phosphor bronze center pin has excellent elasticity and wear resistance, and the gold plating layer can reduce contact resistance and improve oxidation resistance, ensuring that the center pin can still maintain good contact performance after multiple insertions and removals.

[0042] In an optional embodiment: the female end housing 11 and the male end housing 24 are both made of high-performance nylon, and the female end buckle 12 and the male end buckle 27 are both made of high-performance TPA.

[0043] It should be noted that the high-performance nylon shell and plastic shell have high mechanical strength, insulation performance and temperature resistance, can adapt to different working environments, and effectively protect the internal metal parts; the buckle made of high-performance TPA has good elasticity and toughness, which facilitates insertion and removal operations, while providing stable locking force and excellent aging resistance, thus extending the service life of the connector.

[0044] In an optional embodiment: one end of the female zinc alloy body 15 extends into the interior of the male plastic shell 24, and one end of the male zinc alloy 21 is inserted into the interior of one end of the female zinc alloy body 15.

[0045] It should be noted that this nested structure allows the zinc alloy shielding layers of the male and female ends to be tightly connected, forming a continuous shielding barrier. This maximizes the blocking of external electromagnetic interference from entering the internal signal transmission path, while preventing internal signals from leaking outward. This significantly improves the electromagnetic compatibility of the connector and ensures the quality of signal transmission.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
