Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a high-reliability misalignment connector. Background Art

[0002] In a phased array radar with densely arranged elements, when the antenna unit and the TR unit interface are not on the same vertical line, RF coaxial cable assemblies are conventionally used for interconnection. The single-pair plug-in and port identification make the installation process very time-consuming and subsequent maintenance very difficult. Under this circumstance, a "Z"-shaped offset connector has gradually emerged. During installation, the interface at one end of the multi-way offset connector is fixed on the antenna unit and connected to the antenna unit interface, and the interface at the other end is driven by the antenna end fixing plate to be offset and connected to the multi-way interface of the TR at the same time. It is easy to install and maintain, and can achieve interconnection under a smaller spacing state. However, in order to achieve the purpose of radial pitch change, the existing "Z"-shaped offset connector mostly adopts a one-piece molding structure with two 90° bends for the inner conductor. During processing, two bending fixtures and at least two positioning fixtures need to be combined to complete the processing. The processing is complicated, inefficient and has low dimensional accuracy. In addition, in order to facilitate the installation of the integrated inner conductor and the separate insulator, the "Z"-shaped outer conductor is mostly formed by press-fitting two "L"-shaped outer conductors. There is a risk of falling off and causing connection failure in a strong vibration environment, and the reliability is low. Under this background, there is an urgent need for the emergence of an offset connector that is easy to process and has high reliability. Utility Model Content

[0006] Preferably, the insulator consists of insulator one, insulator two and insulator three; insulator two is connected to insulator one and insulator three respectively, and insulator one, insulator two and insulator three are respectively located in three straight line segments of the "Z"-shaped outer conductor.

[0007] Preferably, the outer conductor is provided with a waist-shaped hole with a cover pressed into it on the second 90° offset outer surface, the upper arc of the waist-shaped hole is concentric with the inner hole on the same side of the waist-shaped hole of the outer conductor, and the diameter of the waist-shaped hole arc is larger than the aperture of the inner hole of the outer conductor, so that the insulator 2 with an outer diameter matching the aperture of the inner hole of the outer conductor is installed from this waist-shaped hole.

[0008] Preferably, the inner conductor consists of inner conductor one, inner conductor two and inner conductor three, inner conductor two is elastically connected with inner conductor one and inner conductor three respectively, inner conductor one and inner conductor two are respectively "L-shaped", and inner conductor three is straight.

[0009] Preferably, the length of the short side of the "L-shape" of the inner conductor one is smaller than the diameter of the inner hole at the upper end of the outer conductor, so that the inner conductor one can be easily inserted into the inner hole of the outer conductor from the upper end; the length of the short side of the "L-shape" of the inner conductor two is smaller than the distance from the center of the arc at one end of the waist-shaped hole of the outer conductor to the edge of the arc at the other end.

[0010] Compared with the prior art, the utility model has the following advantages: the utility model reduces the difficulty of processing the inner conductor by splitting the integrated "Z"-shaped inner conductor into two "L"-shaped inner conductors and one linear inner conductor that are elastically contacted and interconnected; the utility model realizes the installation of the upper inner conductor by making the short side of the "L"-shaped inner conductor smaller than the inner hole diameter of the outer conductor to be installed; by setting a waist-shaped hole on the outer conductor, it not only reduces the mechanical processing difficulty of the inner hole in the middle section of the outer conductor, but also provides convenience for the installation of the insulating medium and the inner conductor in the middle section. Through the above measures, the inner conductor and the insulating medium are installed in the integrated "Z"-shaped outer conductor, avoiding the risk of the two "L"-shaped outer conductors falling off after being pressed together, and improving the reliability of the misaligned connector.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] A high-reliability dislocation connector comprises a contact head 1, an inner conductor, an insulator, an outer conductor 8, a pressure ring 9 and a cover 10; the inner conductor, the insulator and the outer conductor 8 are arranged in sequence from the inside to the outside, and the outer conductor 8 achieves the purpose of radial distance change through two 90° dislocation "Z"-shaped structures; the contact head 1 is located at the interface end of the outer conductor 8 and is press-fitted inside the outer conductor 8; the pressure ring 9 is located above the contact head 1 and is riveted A inside the outer conductor 8; the cover 10 is embedded in the inner hole on the surface of the outer conductor 8 and the surface is soldered.

[0018] The outer conductor 8 is provided with a waist-shaped hole C at the second 90° offset outer surface into which the cover 10 is pressed, which reduces the difficulty of machining the inner hole of the middle section of the outer conductor 8. The upper arc of the waist-shaped hole C is concentric with the inner hole on the same side of the waist-shaped hole C of the outer conductor 8, and the arc diameter of the waist-shaped hole C is larger than the inner hole diameter of the outer conductor 8, so that the insulator 2 with an outer diameter matching the inner hole diameter of the outer conductor 8 can be installed from the waist-shaped hole C.

[0019] The inner conductor is composed of an inner conductor 1 2, an inner conductor 3 4, and an inner conductor 2 3 elastically contacting and interconnecting with the inner conductor 1 2 and the inner conductor 3 4. The inner conductor 1 2 and the inner conductor 2 3 are respectively "L-shaped", and the inner conductor 3 4 is linear. By splitting the integrated "Z"-shaped inner conductor into two "L"-shaped inner conductors elastically contacting and interconnecting and one linear inner conductor, the processing difficulty of the inner conductor is reduced.

[0020] The length of the "L-shaped" short side of the inner conductor 1 2 is smaller than the diameter of the inner hole at the upper end of the outer conductor 8, which facilitates the inner conductor 1 2 to be installed into the inner hole of the outer conductor 8 from the upper end; the length of the "L-shaped" short side of the inner conductor 2 3 is smaller than the distance from the arc center of one end of the waist-shaped hole C of the outer conductor 8 to the arc edge of the other end, which facilitates the inner conductor 2 3 to be installed into the inner hole of the insulator 2 6 from the waist-shaped hole C after the insulator 2 6 is installed from the waist-shaped hole C. The inner conductor and the insulating medium are installed into the integrated "Z"-shaped outer conductor 8, avoiding the risk of the two "L"-shaped outer conductors 8 falling off after being pressed together, and improving the reliability of the misaligned connector.

[0021] When assembling the connector, firstly, the inner conductor 12 is installed from the upper end into the inner hole of the outer conductor 8, and then a needle-type tool is inserted into the upper end hole of the inner conductor 12, and the insulator 15 is installed between the outer diameter of the inner conductor 12 and the inner hole of the outer conductor 8 through the needle-type tool; the contact head 1 is pressed into the inner hole of the upper end of the outer conductor 8, that is, the interface end, and then the pressure ring 9 is installed into the inner hole above the contact head 1 of the outer conductor 8, and the pressure ring 9 is fixed by riveting A at the mouth of the outer conductor 8; the insulator 26 is installed into the inner hole of the outer conductor 8 from the waist-shaped hole C, and then the inner conductor 22 is installed into the inner hole of the insulator 26 from the waist-shaped hole C, and is elastically contacted and interconnected with the inner conductor 12, and then the waist-shaped hole C is blocked with a press-fit cover 10, and the surface of the cover 10 is soldered. Then the insulator 37 is installed from the inner hole of the lower end of the outer conductor 8, and the inner conductor 34 is installed in the insulator 37, and is elastically contacted and interconnected with the inner conductor 35. Then rivet B is applied at position B of the outer conductor 8 to fix the insulating medium.

For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
