Description
Technical Field
[0001] The utility model relates to the field of male connectors, and more particularly to a DIN-type male connector for multi-port testing. Background Art
[0002] In the prior art, there are more and more ports on some antennas, RRUs and other devices, and each port is installed with a female connector. When wiring, multiple male connectors need to be installed on each device according to the number of ports. The overall structure of some devices is relatively compact, resulting in a small spacing between ports. In the prior art, the connection between male connectors and female connectors is mostly through threaded connection, but the small spacing between ports will result in a small installation space. The small installation space will make it difficult to connect the male connectors due to space limitations when docking, which is inefficient. In addition, the threaded connection requires the operator to manually connect several male connectors one by one, which has low work efficiency.
[0003] The utility model disclosed in the prior art publication number CN220421017U discloses an anti-reverse overvoltage protection circuit, including a female head, a movable cylinder provided on the outer wall of the female head, a male head provided on one side of the female head, a mounting cylinder provided inside the female head, a mounting column provided inside the mounting cylinder, a movable cylinder provided on the outer wall of the female head, the movable cylinder being slidably mounted on the outer wall of the female head, and by pushing the movable cylinder to one side, the groove of the movable cylinder is moved to above the steel ball, and then the male head is moved to the inside of the female head, and the steel ball is first squeezed on both sides of the male head to move the steel ball upward, and then the male head is moved to a certain position so that the extrusion ring and the sealing ring are fitted, and then the joint and the interface are fitted, and at the same time the steel ball falls into the groove inside the outer wall of the male head, and the movable cylinder is loosened, and the spring drives the movable cylinder to reset, squeezes the steel ball, and limits the steel ball, and at the same time limits the male head by the steel ball to prevent the male head from separating from the female head. Although the above scheme can realize automatic limiting between the male and female heads, it cannot realize the one-time docking of multiple male and female heads. Utility Model Content

DETAILED DESCRIPTION
[0021] The accompanying drawings are for illustrative purposes only and are not to be construed as limiting this patent;
[0022] In order to better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product size;
[0023] It is understandable to those skilled in the art that some well-known structures and descriptions thereof may be omitted in the drawings.
[0024] The technical solution of the present utility model is further described below with reference to the accompanying drawings and embodiments.
[0025] like Figure 1 The figure shows a schematic diagram of the structure of a DIN male connector for multi-port testing. Figure 2 This is a schematic diagram of the connection between a DIN male connector and a female connector for multi-port testing.
[0026] In a specific embodiment, a DIN-type male connector for multi-port testing includes: a male connector body 10, a movable connecting portion 7, and a connector panel 9. The male connector body 10 is connected to the connector panel 9 via the movable connecting portion 7, and the male connector body 10 and the connector panel 9 can slide relative to each other. The male connector body 10 is provided with a threaded gripping portion 12 on the outside to facilitate manual plugging and unplugging by the operator during use. The connector panel 9 is a rectangular metal plate with a thickness of 3 mm and is made of stainless steel. It can withstand multiple plugging and unplugging operations. The surface of the connector panel 9 is provided with mounting holes with a hole diameter of 10 mm according to the positions of several female connector ports on the shell to be tested, and a flange 71 is welded around the mounting hole to ensure the firmness and durability of the installation. By providing the movable connecting portion 7, the position of the male connector on the connector panel 9 can be adjusted in a radial and axial floating manner when multiple male connectors are docked with several female connectors, thereby eliminating the processing errors of the multiple ports of the connector panel 9.
[0027] The outer conductor 1 of the male connector body 10 is made of a highly conductive copper alloy and plated with nickel or gold to prevent oxidation and enhance electrical contact stability. The outer conductor 1 is cylindrical with an inner diameter of 7 mm and an outer diameter of 10 mm. It houses the insulator 2 and inner conductor 3. The insulator 2 is made of polytetrafluoroethylene, offering excellent insulation and high-temperature resistance. It is fixedly mounted within the outer conductor 1 and is 2 mm thick. The inner conductor 3 is made of high-purity copper and has a diameter of 3 mm. It is precisely aligned with the female connector under test, ensuring lossless signal transmission. The right side of the outer conductor 1 is connected to the positioning sleeve 4, which is made of a hard aluminum alloy and anodized for corrosion and wear resistance. The left side is connected to the female connector under test. The positioning sleeve 4 has an inner diameter of 8 mm and houses an insulating sheet 5 and a solder cup 6. The insulating sheet 5 is made of ceramic and is 1 mm thick, effectively isolating the electrical signal. The solder cup 6 is soldered to the wire to provide a secure electrical connection.
[0028] Furthermore, outer conductor 1 is provided with a positioning ring groove 11, which ensures precise mating between the connector and the female connector. This groove is 0.5 mm deep and 2 mm wide, and its end is flared to reduce friction and contact resistance during insertion and removal, thereby improving signal transmission efficiency. The surface of outer conductor 1 is coated with a conductive coating to enhance oxidation resistance and reduce losses during high-frequency signal transmission.
[0029] Furthermore, the movable connection portion 7 includes a positioning sleeve 4, a flange 71 on the connector panel 9, and a spring 72 disposed between the positioning sleeve 4 and the flange 71. The spring 72 is a stainless steel spring with good fatigue resistance. It has a length of 5 mm, a diameter of 6 mm, and a compression stroke of 2 mm. It is used to provide a buffering effect, allowing the connector to adapt to the installation tolerances of different female connectors.
[0030] Furthermore, a 0.5 mm floating gap 74 is provided between flange 71, outer conductor 1, and positioning sleeve 4 to ensure that the male connector body 10 can slide on the connector panel 9 during the mating process between the male and female connectors, eliminating processing errors caused by the multiple ports of the connector panel 9. The flange 71 and positioning sleeve 4 also have interlocking bevels 73 for automatic centering between the flange and the positioning sleeve, allowing the connector to automatically correct alignment when inserted into the female connector, avoiding poor contact caused by insertion angle deviation.
[0031] In actual application, when the user inserts the multi-port test DIN male connector into the female connector of the multi-port test system, the elastic force provided by the spring 72 between the positioning sleeve 4 and the flange 71 can buffer the mechanical impact during the connection process. The floating gap 74 between the flange and the outer conductor 1 allows a certain displacement adjustment to ensure that the position error of different female ports can be absorbed during the connection process, thereby ensuring the stability and accuracy of each connection. At the same time, the design of the automatic centering bevel 73 enables the connector to automatically correct the alignment when inserted, avoiding the problem of poor contact or signal loss caused by incorrect angles in traditional connectors. The trumpet-mouth structure of the positioning ring groove 11 makes the connector smoother during the plugging and unplugging process, effectively improving the test efficiency.
