Description

Technical Field

[0001] This invention relates to the field of connector technology, and more particularly to a right-angled coaxial connector. Background Technology

[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.

[0003] Coaxial connectors are primarily used for high-frequency signal transmission and are widely applied in various fields. In the automotive industry, coaxial connectors are commonly found connecting devices such as GPS antennas, navigation modules, vehicle cameras, broadcasting systems, and sensor modules. The structural design of coaxial connectors involves the inner conductor, which transmits signals, being encased by an outer conductor, thus blocking external interference and ensuring stable signal transmission.

[0004] Common coaxial connectors come in two types: straight and right-angle. Right-angle coaxial connectors allow cables to change direction, making it easier to wire in a limited space. However, because their structure is not as simple as that of straight coaxial connectors, they require a more sophisticated structural design to maintain or improve their performance. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a bent coaxial connector to solve the problems of the prior art.

[0006] The present invention provides a bent coaxial connector to solve the problems of the prior art. The connector comprises: an outer conductor member having a hollow box-shaped portion, a terminal receiving sleeve extending forward from the hollow box-shaped portion, and a cable receiving sleeve extending downward from the hollow box-shaped portion. The outer conductor member has a mating opening at the front end of the terminal receiving sleeve and a cable passage opening at the lower end of the cable receiving sleeve. A component assembly space is formed within the outer conductor member, extending from the mating opening through the terminal receiving sleeve, the hollow box-shaped portion, and the cable receiving sleeve to the cable passage opening; an inner core member assembled within the component assembly space of the outer conductor member; and an inner conductor member assembled within the inner core member. The outer conductor member is a seamless, hole-free component integrally formed by the hollow box-shaped portion, the terminal receiving sleeve, and the cable receiving sleeve, completely covering the component assembly space.

[0007] In one embodiment of this invention, a bent coaxial connector is provided, wherein the outer conductor component is a die-cast metal part.

[0008] In one embodiment of this invention, a bent coaxial connector is provided, wherein the front edge of the terminal receiving sleeve of the outer conductor member is a riveted end edge that is shaped and recessed, and stops at the front side of a crown spring provided inside the terminal receiving sleeve of the outer conductor member.

[0009] In one embodiment of this invention, a bent coaxial connector is provided, which further includes a housing component that is fitted over the outer conductor component.

[0010] In one embodiment of this invention, a bent coaxial connector is provided, wherein the housing component is sleeved outside the terminal receiving sleeve of the outer conductor component.

[0011] Preferably, in one embodiment of the present invention, a bent coaxial connector is provided, wherein a sealing connection seat is formed at the lower end of the cable receiving tube portion of the outer conductor member for fastening with a sealing retainer to waterproof and seal the cable through the opening.

[0012] In one embodiment of this invention, a bent coaxial connector is provided, wherein the hollow box-shaped portion of the outer conductor member is a rounded cuboid shape.

[0013] In one embodiment of this invention, a bent coaxial connector is provided, wherein the bent coaxial connector is a bent coaxial high-frequency wire harness connector.

[0014] Through the technical means employed in this invention, the elbow coaxial connector completely encloses the component assembly space in its structure, eliminating holes and seams. This effectively prevents foreign object intrusion and provides excellent electromagnetic shielding. Furthermore, in this elbow coaxial connector, the outer conductor component is integrally formed, reducing the number of parts. This not only improves structural strength but also effectively reduces manufacturing process and component costs. Attached Figure Description

Detailed Implementation

[0023] The following description, based on Figures 1 through 6, illustrates an embodiment of the invention. This description is not intended to limit the implementation of the invention, but rather to provide one possible example.

[0024] As shown in Figures 1 to 4, a bent coaxial connector 100 according to Embodiment 1 of this invention includes: an outer conductor member 1 having a hollow box-shaped portion 11, a terminal receiving sleeve portion 12 extending forward from the hollow box-shaped portion 11, and a cable receiving sleeve portion 13 extending downward from the hollow box-shaped portion 11; the outer conductor member 1 has a engagement opening 121 at the front end of the terminal receiving sleeve portion 12 and a cable passage opening 131 at the lower end of the cable receiving sleeve portion 13; and a component assembly space 10 is formed in the outer conductor member 1 extending from the engagement opening 121 through the terminal receiving sleeve portion 12, the hollow box-shaped portion 11, and the cable receiving sleeve portion 13 to the cable passage opening 131; an inner core member 2 assembled in the component assembly space 10 of the outer conductor member 1; and an inner conductor member 3 assembled in the inner core member 2.

[0025] As shown in Figures 1 to 4, the elbow coaxial connector 100 of Embodiment 1 of this invention is characterized in that: the outer conductor member 1 is an integrally formed, hole-free, seamless member consisting of the hollow box-shaped portion 11, the terminal receiving sleeve portion 12, and the cable receiving sleeve portion 13, which completely cover the assembly space 10. That is, apart from the inherent engagement opening 121 for engaging with the terminal and the cable passage opening 131 for introducing the cable, there are no other holes in the hollow box-shaped portion 11, the terminal receiving sleeve portion 12, and the cable receiving sleeve portion 13 of the outer conductor member 1. Furthermore, since the hollow box-shaped portion 11, the terminal receiving cylinder portion 12, and the cable receiving cylinder portion 13 are integrally formed, there are no joint gaps or marks formed by the joining of components between the hollow box-shaped portion 11 and the terminal receiving cylinder portion 12, or between the hollow box-shaped portion 11 and the cable receiving cylinder portion 13. Of course, even considering individual parts of the hollow box-shaped portion 11, the terminal receiving cylinder portion 12, and the cable receiving cylinder portion 13, since they are also integrally formed and not assembled from separate parts or machined from sheet metal, there are also no joint gaps or marks formed by the joining of components or parts.

[0026] With the above structure, the elbow coaxial connector 100 of this invention completely covers the component assembly space 10, without any holes or seams, thus effectively preventing the intrusion of foreign objects and providing excellent electromagnetic wave shielding. Furthermore, in the elbow coaxial connector 100 of this invention, the outer conductor component 1 is integrally formed, reducing the number of parts, which not only improves the structural strength but also effectively reduces the manufacturing process and component costs.

[0027] Preferably, in the elbow coaxial connector 100 of this invention, the outer conductor member 1 is a die-cast metal part. In other words, the outer conductor member 1 is integrally formed by die casting.

[0028] Preferably, in the elbow coaxial connector 100 of this embodiment, the front end edge of the terminal receiving sleeve 12 of the outer conductor member 1 is a riveted end edge 122 that has been shaped and recessed, and it stops at the front side of a crown spring 14 provided inside the terminal receiving sleeve 12 of the outer conductor member 1. Specifically, in the prior art, in order to prevent the crown spring 14 from falling off, an independent mating cover is embedded at the front end of the outer conductor member 1 to stop the crown spring 14. However, the mating cover itself is prone to peeling off under external force, and a gap is formed at the joint between the mating cover and the outer conductor member 1, which allows foreign objects to easily seep in and cause damage. In contrast, the structure of the riveted end edge 122 provided by the elbow coaxial connector 100 of this embodiment can effectively prevent the crown spring 14 from falling off without causing the above-mentioned problems of peeling off under external force and foreign object seepage.

[0029] Preferably, as shown in Figures 1 and 2, the elbow coaxial connector 100 of this embodiment further includes a housing component 4, which is sleeved on the outer conductor component 1. Specifically, in this embodiment, the housing component 4 is sleeved on the terminal receiving sleeve portion 12 of the outer conductor component 1.

[0030] Preferably, as shown in Figures 5 and 6, in the elbow coaxial connector 100a of Embodiment 2 of this invention, a sealing connection seat 15 is formed at the lower end of the cable receiving sleeve portion 13 of the outer conductor member 1, for fastening with a sealing retainer 5 to waterproofly seal the cable passing through the opening 131. That is to say, the elbow coaxial connector of this invention can be applied not only to the general non-waterproof elbow coaxial connector 100 shown in Figures 1 to 4, but also to the waterproof elbow coaxial connector 100a shown in Figures 5 and 6.

[0031] Preferably, as shown in Figures 1 to 6, in the elbow coaxial connectors 100 and 100a of Embodiments 1 and 2 of this invention, the hollow box-shaped portion 11 of the outer conductor member 1 is a rounded cuboid shape.

[0032] Preferably, as shown in Figures 1 to 6, in the elbow coaxial connectors 100 and 100a of Embodiments 1 and 2 of this invention, the elbow coaxial connectors 100 and 100a are elbow coaxial high-frequency wire harness connectors, such as FAKRA (Fachkreis Automobil) connectors commonly used in automotive audio and antenna specifications in the automotive field.

[0033] The above description and explanation are merely illustrative of preferred embodiments of this invention. Those skilled in the art may make other modifications based on the following defined scope of the patent application and the above description, but such modifications shall still be within the spirit of this invention and the scope of its rights.
