FIG. 3 shows the finished product of the assembled SMA male part, the length is 9.65mm, the diameter is phi 5.25mm, the overall length and the outer diameter are much smaller than those of the traditional male connector, and meanwhile, the part cost is saved;

as shown in figure 4, the assembled finished product of the SMA female part has the length of 13.75mm and the diameter of 5.25mm, and the overall length and the external diameter are much smaller than those of the traditional female connector, and meanwhile, the part cost is saved.

The connector in the 5G test equipment is small in size and low in cost, the connector needs to be integrally miniaturized, and the reliability of the structure of the connector product needs to be guaranteed to realize the miniaturization of the connector. As shown in fig. 5 and 6, the male central needle and the female central needle are both specially treated in structure: the side walls of the male head center pin and the female head center pin, which are close to the middle position, are provided with roller flower barbs, so that the male and female center pins are prevented from retreating after the male and female connectors are matched, the rotation of the center pins of the male and female connectors during thread matching is also prevented, the inner conductor of the cable is protected from being well contacted with the center pins, and the inner conductor of the cable is prevented from being twisted off; the side walls of the male head center needle and the female head center needle close to the end parts are provided with hanging platforms, so that the male connector and the female connector are prevented from being pulled out after being matched.

As shown in fig. 7 and 8, when the cable is fixed with the SMA male and female connectors, the structure is as follows: the connector body and the insulator are fixed by the body barb to prevent the central pin from being pushed out after being inserted into the insulator; the inner conductor of the cable is welded with the center pin, the inner braided layer of the cable is welded with the welding cup, the outer braided stainless steel wire of the cable is turned upwards, the main body and the tail pipe are fixedly connected in a punching mode, and the tail pipe and the cable are fixedly filled with epoxy resin, so that the reliability of the whole connector is optimal, and the actual application condition can be met.

When the connector is actually installed and applied, when the ports of two devices are arranged side by side or staggered up and down or the installation space is narrow, the cable needs to be bent or turned in the connection process, the cable above the connector can be bent for 90 degrees along the 5mm position of the root of the connector, the connector can be used as an elbow, namely, one elbow connector is omitted, the two ports are not affected when being interconnected, and the normal working operation of the two devices is ensured, as shown in fig. 9 and 10.

When the ports of the two devices are installed in parallel, and the cable needs to be slightly bent or turned in the connection process, the connector keeps the straight function in normal use, the two ports are mutually not affected when being interconnected, and the two devices can work normally, as shown in fig. 11 and 12.

First, cable and SMA connector holding force test

After the detection device is adjusted to a state to be detected, the selection of a test software program is completed, and a test article is arranged on test equipment according to requirements to prepare for testing.

Second, SMA connector electrical performance test

The SMA male and female connectors and the cable are assembled respectively, and the SMA male and female connectors and the cable are tested with a scale network analyzer, and the theoretical requirements are as follows: VSWR <1.2@ DC-26.5 GHZ. The standing wave (VSWR) of the SMA male connector was actually tested to be 1.15, and as a result of the test of fig. 14, the standing wave appeared to have a maximum value of 1.15 at 23.19GHz, apparently satisfying the predetermined target value; the SMA female connector was actually tested for a standing wave (VSWR) of 1.11, and as a result of the test of fig. 15, the standing wave exhibited a maximum value of 1.11 at 21.24GHz, and apparently also satisfied the predetermined target value.
