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, a DIN-type flange connector with improved intermodulation is provided. An intermodulation contact ring 2 is provided in the middle of the flange surface of the DIN-type flange connector 1 in contact with the panel.

[0025] like figure 2 As shown, the flange surface is square, and each of the four corners of the square has a screw hole 5. The screw hole 5 of the DIN flange connector 1 is higher than the flange surface to form a pad 3. There are four pads 3, four 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 35 mm, and the center of the circle is located at the cente...

Abstract

The invention discloses an intermodulation-improved DIN type flange connector. A circle of intermodulation contact ring (2) is arranged on a center of a flange face of the DIN type flange connector (1), wherein the flange face contacts with a panel. Positions of screw holes (5) of the DIN type flange connector (1) are higher than the flange face so as to form pads (3). However, the height of the pad (3) is not higher than the height of the ntermodulation contact ring. The pads (3) distribute uniformly. An internal contour of the each pad (3) is an circular arc. The arcs of the internal contours of the each pad (3) are in a same circle. In the invention, a structure is simple. Installation is reliable. An operation of production line workers can be simplified. Working difficulty of the workers can be reduced. Time can be saved. A production efficiency can be improved. The connector is suitable for an actual situation of on-site installation and the quality of an intermodulation index can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of wireless microwave communication, in particular to a DIN flange connector with improved intermodulation. Background technique [0002] Ordinary DIN flange connectors are 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, destruc...
