In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.

[0029] The present application relates to an insertion loss test fixture, comprising an insertion loss colback 1000 and an SMA connector 3000. The insertion loss colback 1000 is provided with at least one SMA connector 3000, and is provided with at least one test area 1100. The SMA connector 3000 is arranged in the test area 1100, and the test area 1100 has signal holes and ground holes. Furthermore, the insertion loss test fixture includes at least one quick-release fixture 2000, which is used to fit over the SMA connector 3000 and secure the SMA connector 3000 to the test area 1100.

[0030] Specifically, the quick-release fastener 2000 is mounted on the SMA connector 3000 and connected to the insertion loss collar 1000. In this case, the quick-release fastener 2000 is attached to the surface of the SMA connector 3000 and can apply pressure to the SMA connector 3000 to secure the SMA connector 3000 to the test area 1100.

[0031] The number of quick-release fixtures 2000 is consistent with the number of test areas 1100. The insertion loss test fixture is equipped with a quick-release fixture 2000 for each test area 1100, so that the SMA connector 3000 can be fixed to the corresponding test area 1100 in a quick-release manner, so that the SMA connector 3000 can be fixed to the insertion loss tester 1000 in an installation-free manner, thereby improving the efficiency of disassembly and assembly.

[0032] Furthermore, the insertion loss Cobon 1000 is provided with at least one pair of quick-release structures 1200 for detachably connecting the two ends of the quick-release fixing part 2000. The two pairs of quick-release structures 1200 are spaced apart along the width direction of the insertion loss Cobon 1000. The quick-release fixing part 2000 is arranged along the width direction of the insertion loss Cobon 1000 and the two ends are detachably connected to the quick-release structure 1200 respectively.

[0033] It is understood that the insertion loss Colback 1000 is provided with at least one pair of quick-release structures 1200 for each test area 1100, and the test area 1100 is located between the paired quick-release structures 1200. When the insertion loss Colback 1000 is configured with a pair of quick-release structures 1200 for the test area 1100, the test area 1100 is located between the two paired quick-release structures 1200, and the two ends of the quick-release fixture 2000 are detachably connected to the two paired quick-release structures 1200. When the insertion loss Coback 1000 is configured with at least two pairs of quick-release structures 1200 for the test area 1100, the test area 1100 is located in the center between the quick-release structures 1200, and the two ends of the quick-release fixture 2000 are respectively detachably connected to the quick-release structures 1200 located on both sides of the test area 1100, so that the quick-release fixture 2000 is evenly stressed when connected to the insertion loss Coback 1000, thereby stably fixing the SMA connector 3000 to the test area 1100.

[0034] In some embodiments, the quick release fixing member 2000 is provided with a quick release buckle 2100 at each end thereof for connecting the quick release structure 1200, and the quick release fixing member 2000 can be quickly and detachably connected with the quick release structure 1200 through the quick release buckle 2100.

[0035] Further, the quick release buckle 2100 is provided as an elastic member, and the quick release buckle 2100 can generate elastic potential energy when being pulled. When the quick release buckles 2100 at both ends thereof are connected with the quick release structure 1200 respectively, the quick release buckles 2100 are elastically deformed by being pulled, and can generate elastic force on the quick release fixing member 2000, so as to connect the quick release fixing member 2000 to the insertion loss coaxial connector 1000, and the quick release fixing member 2000 can generate pressure on the SMA connector 3000, thereby fixing the SMA connector 3000 to the test area 1100.

[0036] In some examples, the quick release buckle 2100 is made of rubber material, and has good tensile deformation capacity and soft hand feeling.

[0037] It should be noted that the quick release buckle 2100 is integrally formed with the quick release fixing member 2000 as an elastic structure. Alternatively, the quick release buckle 2100 is fixedly connected to the end of the quick release fixing member 2000 as an elastic member.

[0038] In some examples, the quick release buckle 2100 includes a clamping portion, which is arranged on the side of the quick release fixing member 2000 facing the insertion loss coaxial connector 1000 and is spaced apart from the quick release fixing member 2000. The side of the quick release fixing member 2000 facing the insertion loss coaxial connector 1000 and the clamping portion form a clamping groove 2101 for accommodating the quick release structure 1200.

[0039] The quick release buckle 2100 includes a connecting portion, one end of the clamping portion is connected with the quick release fixing member 2000 through the connecting portion, and the other end extends along the length direction of the quick release fixing member 2000, so as to form the clamping groove 2101 between the clamping portion and the quick release fixing member 2000.

[0040] It can be understood that when the quick release fixing member 2000 is installed with the insertion loss coaxial connector 1000, the quick release buckle 2100 is deformed by force, so that the clamping groove 2101 can be sleeved on the quick release structure 1200, thereby realizing the connection between the quick release buckle 2100 and the quick release structure 1200.

[0041] Furthermore, the quick-release structure 1200 extends along the width of the insertion colback 1000, away from the insertion colback 1000. In this case, the quick-release structure 1200 is formed as a raised structure along the width of the insertion colback 1000, so that the engaging slot 2101 can be fitted onto the quick-release structure 1200. In some examples, the raised shape of the quick-release structure 1200 is rectangular or trapezoidal.

[0042] It should be noted that when at least two pairs of quick-release structures 1200 are provided, the quick-release structures 1200 are spaced apart along the length of the insertion colback 1000 at both sides of the insertion colback 1000. Accordingly, when at least two test areas 1100 are provided, the test areas 1100 are spaced apart along the length of the insertion colback 1000, and the quick-release fasteners 2000 are spaced apart along the length of the insertion colback 1000.

[0043] Regarding the arrangement of the quick release buckle 2100 on the quick release fastener 2000 , there are at least the following alternative embodiments.

[0044] In some alternative embodiments, the quick-release buckle 2100 includes a snap ring, which is connected to the end of the quick-release fixing part 2000. The end of the quick-release fixing part 2000 is detachably connected to the quick-release structure 1200 by being sleeved on the quick-release structure 1200 through the snap ring.

[0045] In some implementations, the test area 1100 is provided with a positioning structure for installing the SMA connector 3000 , so that the SMA connector 3000 is accurately arranged in the test area 1100 .

[0046] Specifically, the positioning structure includes at least two first positioning holes 1300 arranged at intervals, and the first positioning holes 1300 extend along the thickness direction of the insertion loss connector 1000. A first positioning column 3201 is provided on the side of the SMA connector 3000 facing the insertion loss connector 1000. The first positioning column 3201 is upright on the side of the SMA connector 3000 facing the test area 1100. The SMA connector 3000 is accurately positioned in the test area 1100 by inserting the first positioning column 3201 inserted in the first positioning hole 1300.

[0047] It can be understood that the number of the first positioning columns 3201 and the first positioning holes 1300 are the same, and their positions correspond to each other.

[0048] In some examples, the first positioning holes 1300 in the positioning structure are spaced apart along a circumference surrounding the center of the test area 1100. Of course, the distribution of the first positioning holes 1300 can also be alternatively set to: the first positioning holes 1300 are spaced apart along the width direction or the length direction of the insertion loss colback 1000.

[0049] It should be noted that the positioning structure has at least the following alternative embodiments.

[0050] In some alternative embodiments, the positioning structure includes at least two second positioning posts arranged at intervals, and the second positioning posts are uprightly provided on the insertion loss Colback 1000 for arranging the side of the SMA connector 3000. Furthermore, the SMA connector 3000 is provided with a second positioning hole.

[0051] Furthermore, the second positioning posts in the positioning structure are spaced apart along a circumference surrounding the center of the test area 1100. Alternatively, the distribution of the second positioning posts can be alternatively designed as follows: the second positioning posts are spaced apart along the width or length of the insertion loss colback 1000.

[0052] In some other alternative embodiments, the positioning structure is configured as a positioning groove on the side of the insertion loss Coback 1000, the positioning groove is concavely formed, and the positioning groove is adapted to the shape of the side of the SMA connector 3000 facing the insertion loss Coback 1000.

[0053] In some embodiments, the quick release fixture 2000 is provided with an avoidance through hole 2200 , which penetrates the quick release fixture 2000 along the thickness direction of the quick release fixture 2000 . The quick release fixture 2000 can be mounted on the SMA connector 3000 through the avoidance through hole 2200 .

[0054] Specifically, the SMA connector 3000 includes a connector 3100 and a base 3200. The connector 3100 is mounted on the base 3200, with the other side of the base 3200 facing the test area 1100. The quick-release fixture 2000 is mounted on the connector 3100 of the SMA connector 3000 through the avoidance through-hole 2200. The side of the quick-release fixture 2000 is in contact with the surface of the base 3200 and can apply pressure to the base 3200, thereby securing the SMA connector 3000 to the test area 1100 of the insertion loss tester 1000.

[0055] Based on the above introduction to the insertion loss test fixture, the insertion loss test fixture has at least the following alternative implementations.

[0056] The insertion loss test fixture includes an insertion loss colback, an SMA connector and at least one quick-release fixture. The insertion loss colback has the test area as described above. The quick-release fixture is arranged along the width direction of the insertion loss colback. The quick-release fixture is used to be sleeved on the SMA connector and fix the SMA connector to the test area.

[0057] Furthermore, the insertion loss colback is equipped with at least one quick-release structure, with at least one quick-release structure configured for each test area. Specifically, the quick-release structures and the test areas are spaced apart along the width of the insertion loss colback. One end of the quick-release fixture is fixed to the insertion loss colback, and the other end is detachably connected to the quick-release structure. In this way, each time one end of the quick-release fixture is removed or installed, the SMA connector can be quickly installed or removed from the insertion loss colback, improving efficiency.

[0058] It is understandable that a quick-release buckle is provided at the other end of the quick-release fixing member, and the quick-release fixing member is detachably connected to the quick-release structure through the quick-release buckle.

[0059] It should be noted that the structures of the quick-release structure and the quick-release buckle are as described above. Furthermore, when there are at least two quick-release structures, the quick-release structures are spaced apart along the length of the insertion colback at one edge of the insertion colback.

[0060] In some examples, the quick-release fastener is provided with an avoidance through-hole for being sleeved on the SMA connector, and the structure of the avoidance through-hole is as described above.
