Problems solved by technology

When the two tilted screws are tightened, the flange surface is likely to be arched, resulting in the intermodulation contact ring not being able to fit the panel at 360 degrees, resulting in deterioration of the intermodulation index

Embodiment

[0024] Example: such as figure 1 , figure 2 As shown, an N-type flange connector with improved intermodulation is provided. An intermodulation contact ring 2 is provided in the middle of the flange surface of the N-type flange connector 1 in contact with the panel.

[0025] Such as figure 2 As shown, the flange surface is square, and there is a screw hole 5 on each of the four corners of the square. The screw hole 5 of the N-type flange connector 1 is higher than the flange surface to form a pad 3, and there are four pads 3 in total. The feet 3 are evenly distributed, and the outer contour of each foot 3 coincides with the outer edge of the flange, so that when the flange edge is processed, the outer contour of the foot 3 is processed simultaneously. The inner contours of the four pads 3 are designed to be arc-shaped, and they are connected to form a circle, that is to say, they are on the same circle. The diameter of this circle is 25.4 mm, and the center of the circle is...

Abstract

The invention discloses an N-type flange connector with improved cross modulation. The N-type flange connector (1) has a flange face which is in contact with a panel; the flange face is a square; four corners of the square are respectively provided with a screw hole (5); a cross modulation contact ring (2) which is higher than the flange face is arranged in the middle of the flange face; the positions of the screw holes (5) of the N-type flange connector (1) are higher than the flange face to form foot mats (3); the heights of the foot mats (3) are not higher than that of the cross modulation contact ring (2); the internal contours of the foot mats (3) are in arc shapes; and the arc shapes of the internal counters of the four foot mats (3) are positioned in the same circle. The N-type flange connector with the improved cross modulation has a simple structure and is reliable to mount; the operation of a worker on a production line is simplified; the work difficulty of the worker is decreased; the time is saved; the production efficiency is improved; the N-type flange connector with the improved cross modulation is suitable for actual conditions in field mounting; and the goodness of cross modulation indexes can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of wireless microwave communication, in particular to an N-type flange connector with improved intermodulation. Background technique [0002] The ordinary N-type flange connector is connected to the panel of the microwave device through screws, which completes the mechanical connection, and also completes the electrical connection due to the contact between the flange and the panel. In the absence of intermodulation requirements, such an installation can fully meet the various mechanical and electrical index requirements of the system. [0003] With the vigorous development of the communication industry, various radio frequency applications emerge in an endless stream. The country allocates corresponding frequency bands for each application. For example, the frequency bands used by GSM are 890MHz to 960MHz, and the frequency bands used for each application must be separated by a certain frequency. Otherwise...
