Description

Technical Field

[0001] The utility model belongs to the field of test connectors, and in particular relates to a quick-lock anti-retraction test connector. Background Art

[0002] In the multi-channel matrix switch test application environment, the staff needs to quickly use the test cable assembly to test the interconnection of the device under test and obtain a fast and accurate test result. Usually, there are many connector ports in the matrix switch, at least 50 or more. The traditional connection method uses a screw-type structure interconnection, and then uses a torque wrench to lock the cable assembly. After the test is completed, the connector on the cable assembly is removed to test the next matrix switch. At present, this method has a big disadvantage, that is, manual mechanical connection and disassembly is very time-consuming and inefficient. At the same time, the distance between the matrix switch connector ports is relatively close, and the use of a torque wrench will also be interfered, which is very inconvenient. Therefore, a new connector that can be quickly connected and disassembled is needed to meet the challenges and needs of the current application environment.

[0003] See attached figure Figure 1 and Figure 2 , Figure 1 The female end 10P of a conventional threaded connector cable assembly is shown. Figure 2 The male end 20P of a conventional threaded connector cable assembly is shown. The female end 10P includes a 1 / 4-36UNS-2A thread 11P, the male end 20P includes a 1 / 4-36UNS-2B thread 21P, a screw sleeve 22P, a retaining ring 23P, and a main body 24P, and the male end 20P is connected to a cable 25P. When installing and applying conventional threaded connector cable assemblies, they are usually screwed in by matching the male and female threads. Since the initial pre-installation is done by hand, the male end screw sleeve is hand-tightened and screwed into the outer thread of the female end. The thread can only be tightened by about 70-80%, and the remaining 20% ​​of the thread needs to be tightened with the help of a torque wrench or a fixed wrench. During the test of the RF cable assembly, if the male and female screw sleeves are not tightened, the tested standing wave / insertion loss, mechanical phase, and mechanical amplitude will be too large, affecting the final test results and making it unusable. On the other hand, production staff have to use torque wrenches to tighten one by one and then disassemble them, which is very time-consuming and labor-intensive, inefficient, and tiring for production staff to operate. Frequent threaded connections will cause slight wear of the threads and generate metal debris. If not cleaned up in time, the metal debris may fall on the insulating medium of the connector. Excessive accumulation of metal debris will also lead to the risk of poor electrical performance such as short circuits. Utility Model Content

Figure 5 The partial cross-sectional structure of the quick-lock anti-retraction test connector when it is in a locked state is shown.

[0024] Example 1.

[0025] Preferably, a quick-lock anti-retraction test connector is used to test a test cable 70, a quick-lock anti-retraction test connector female connector 100 and a male connector 200, and the male connector 200 includes:

[0026] Center needle 10;

[0027] Front end insulator 20;

[0028] The main body 30 is externally connected to the center pin 10, and the front insulator 20 is located between the main body 30 and the center pin 10;

[0029] The lock 40 and the outer conductor 50, the lock 40 is provided with a lock tail claw piece 41, the outer conductor 50 is provided with an outer conductor front claw piece 51, the outer conductor 50 is provided with a W-shaped groove 52 and a step 53 on the outer periphery of the rear end, the lock tail claw piece 41 (when in a locked state) abuts against the step 53, the lock tail claw piece 41 and the W-shaped groove 52 are slidably matched, and the outer conductor front claw piece 51 (when in a locked state) clamps the tail of the female connector 100.

[0030] The male connector further includes a tail insulator 60 , and there is a distance between the front insulator 20 and the tail insulator 60 (they are not in contact with each other).

[0031] The lock buckle 40 is made of beryllium copper.

[0032] The outer conductor 50 is made of beryllium copper.

[0033] There is a first slope 54 between the step 53 and the W-shaped groove 52 , and there is a second slope 55 on a side of the step 53 away from the W-shaped groove 52 .

[0034] The angle of the first slope 54 is preferably 45°, and the angle of the second slope 55 is preferably 45°.

[0035] The working process of the quick-lock anti-retraction test connector of this embodiment is described below.

[0036] See attached figure Figure 3-5 Specifically, in the internal structure of the connector, the original thread on the outer conductor sleeve is changed into an elastic claw structure, and the outer conductor is divided into a lock 40 and a claw 50 from the original sleeve 22P, buckle 23P and main body 24P. First, open the lock 40 and pull it to the right to pre-match the male connector (male end, the same below) and the female connector (female end, the same below). First, open the front claw 51 of the outer conductor and push it directly to the left to the bottom, and then pull the lock 40 to the left to complete the matching of the male connector and the female connector. At the same time, the outer peripheral edge of the rear end of the outer conductor 50 is provided with a W-shaped groove 52, and the claw 41 at the tail of the lock cooperates with the W-shaped groove 52 to achieve locking and opening actions, making it more convenient to connect and disassemble the test connector, and there is no need to tighten the sleeve with a torque wrench, which improves the efficiency of production personnel testing.

[0037] The design background of the quick-lock anti-retraction test connector of this embodiment is described below.

[0038] See attached figure Figure 1-2 Specifically, in order to solve the problems of slow connection and disassembly and easy loosening of the screw sleeve when installing and applying the traditional threaded connector test cable, it is necessary to design the traditional threaded connector with a structure that can be quickly installed and disassembled. Since the traditional threaded connector has threads inside the screw sleeve, it is necessary to use hands and a torque wrench to rotate the screw sleeve in circles during installation, which is time-consuming and inefficient. At the same time, if the screw sleeve is rotated too tightly, it will be difficult to disassemble. If the screw sleeve is rotated too loosely, the data performance of the product test will be abnormal. Therefore, it is necessary to achieve fast installation and disassembly, while ensuring that the connector is not easy to loosen after mating, and does not affect product performance. A quick-lock anti-retraction test connector came into being.

[0039] The design principle of the quick-lock anti-retraction test connector of this embodiment is described below.

[0040] See attached figure Figure 3-5 Specifically, the lock buckle 40 is made of beryllium copper, has a good rebound function, can withstand at least 500 pull-outs, and the elastic function does not fail. The function of the lock buckle 40 is: in the natural unlocked state, pull it to the far right to push the male and female connectors together, and the front claw piece 51 of the outer conductor opens to release space. At the same time, the lock buckle 40 will not fall off when it is pulled to the far right, and will be blocked by the step 53 of the outer conductor 50. The outer conductor 50 is made of beryllium copper, has a good rebound function, can withstand at least 500 pull-outs, and the elastic function does not fail. The function of the outer conductor 50 is: when the lock buckle 40 is pulled to the far left, the lock buckle 40 gradually brings the front claw piece 51 of the outer conductor together from the open state, that is, the lock buckle 40 completely wraps the front claw piece 51 of the outer conductor, so that the contraction clamping force of the outer conductor 50 will not fail. Furthermore, the outer conductor front claw piece 51 clamps the female thread tail, and the outer conductor front claw piece 51 and the female thread tail have a 45° angle, which fits perfectly. The female connector can be quickly connected well, and the lock tail claw piece 41 cooperates with the W-shaped groove 52. The two sides of the step 52 have a first slope 54 and a second slope 55 with a 45° angle, so that the lock 40 will not be easily loosened by the force in the diameter direction of the outer conductor front claw piece 51. The lock 40 must be pulled with horizontal force to unlock and open, thereby realizing the quick disassembly function. The pulling force is appropriate, the feel is controllable, and effortless. At the same time, it can ensure that the mechanical properties of the product after matching and the electrical performance test are not affected.

[0041] The verification results of the quick-lock anti-retraction test connector of this embodiment are described below.

[0042] Specifically, when using the traditional threaded connector for testing, the production staff disassembles very slowly, the connector is easy to loosen, the tightening force of the screw sleeve is difficult to control, the test efficiency is very slow, and 3 test cable assemblies are tested per minute. When using the quick-lock anti-retraction test connector of this embodiment for testing, the production staff can disassemble easily, the connector is not easy to loosen, no torque wrench is needed to lock, only push and pull are needed, the male and female connectors can be well matched, and the test efficiency is greatly improved, and 10 test cable assemblies can be tested per minute.

[0043] The following is a summary analysis of the quick-lock anti-retraction test connector of this embodiment.

[0044] Specifically, through experimental verification, it is known that in the fast testing application scenarios and multi-port matrix switch test application environments, the test cables of traditional threaded connectors need to be frequently disassembled and installed. The threaded connectors cannot quickly test the performance of the entire set of equipment within a unit of time, and are very inconvenient, resulting in low testing efficiency for production personnel.

[0045] When the quick-lock anti-retraction test connector of this embodiment is used for testing, by pushing and pulling the lock 40, it is very convenient for production personnel to disassemble the connector in the quick-lock test scenario. After the male and female connectors are matched in place, the connectors are not easy to loosen, and the testing efficiency of production personnel is greatly improved.
