Description

Technical Field

[0001] The present invention relates to the technical field of radio frequency connector production, and more specifically, to an intelligent test device for the connection performance of a radio frequency connector. Background Art

[0002] When testing an RF connector in the prior art, the RF connector is first inserted into a test machine to connect the RF connector to the circuit in the test machine, and the transmission stability of the RF connector is tested through the test machine. However, the pins of some RF connectors are exposed, which causes pin collision during the transfer of the RF connector, thereby causing the pins to be bent. When the RF connector with bent pins is connected to the test machine for testing, insertion failure occurs, resulting in test failure. Therefore, existing equipment will set up a detection mechanism and a correction mechanism above the test machine. When testing the RF connector, the pins of the RF connector are first detected by the detection mechanism. When the pins are detected to be bent, the bent pins are corrected by the correction mechanism, and then the RF connector is inserted into the test machine for testing. The operation process is cumbersome and inefficient. Summary of the invention

[0003] In order to overcome the shortcoming of low testing efficiency of radio frequency connectors with bent pins in existing equipment, the present invention provides an intelligent testing device for connection performance of radio frequency connectors.

[0004] The technical solution is: A radio frequency connector connection performance intelligent test device comprises a tester and a socket; a plurality of sockets are installed on the tester; the device also comprises a connection block, a cylinder, a spring 1 and a round rod; each socket is fixedly connected to a connection block; each connection block is slidably connected to a plurality of cylinders; each cylinder is fixedly connected to a spring 1, and the other end of the spring 1 is fixedly connected to the corresponding socket; each socket is fixedly connected to a plurality of round rods, the round rods are connected to the tester, and the round rods are slidably connected to the corresponding cylinders; each cylinder is provided with a cone surface portion 1; each round rod is provided with a cone surface portion 2, and the cone surface portion 2 and the corresponding cone surface portion 1 are located on the same cone surface.

[0005] Furthermore, it also includes a limit assembly; the limit assembly is connected to the socket; the limit assembly includes a limit block and a linkage unit; each socket is slidably connected with at least two limit blocks, and the limit blocks are located on the lower side of the corresponding cylinder; the socket is connected to the linkage unit, and the linkage unit is used to drive the limit block to move horizontally.

[0006] Furthermore, the linkage unit includes a linkage block and a spring 2; at least two linkage blocks are fixedly connected to each limit block, and the linkage blocks cooperate with the RF connector body; a spring 2 is commonly fixedly connected between each linkage block and the corresponding socket; four inclined portions are arranged on the RF connector body, and the inclined portions cooperate with the corresponding linkage blocks.

[0007] Furthermore, the linkage block is configured to be made of a non-conductive wear-resistant material.

[0008] Furthermore, it also includes an auxiliary component; the auxiliary component is connected to the cylinder; the auxiliary component includes a ring, a spring three, a pressure sensor and a buzzer; each cylinder is slidably connected to a ring; at least two springs three are fixedly connected between each ring and the corresponding cylinder; a pressure sensor is fixedly connected between each ring and the corresponding cylinder; and a buzzer is installed on the tester.

[0009] Furthermore, it also includes friction blocks; at least four friction blocks are fixedly connected to each socket.

[0010] Furthermore, the friction block is detachably connected to the corresponding socket.

[0011] Furthermore, it also includes a clamping assembly; the clamping assembly is connected to the socket; the clamping assembly includes a fixed block, a spring four and a pipe; each socket is sealed and slidably connected with at least two fixed blocks; at least two springs four are fixedly connected between each fixed block and the corresponding socket; and at least two pipes are fixedly connected to each socket.

[0012] Furthermore, the fixing block is provided with a plurality of grooves.

[0013] Furthermore, a chamfer is provided at the opening of the socket.

[0014] The beneficial effects are: 1. Manually, the RF connector body only needs to be inserted into the socket, and the cylinder and the round rod can be matched to automatically test the RF connector body with bent pins. Compared with the existing equipment, this equipment does not need to perform pin bending detection and pin bending correction operations, which reduces the working steps and is conducive to improving efficiency. At the same time, through the cooperation of the cylinder and the spring, after the cylinder guides the pin part, it can automatically avoid downward, so that the relatively short pin part can still be stably inserted into the round rod to ensure the stability of the RF connector body test operation. At the same time, the avoidance process of the cylinder is completed in conjunction with the insertion of the RF connector body, and the structure is ingenious; Second, the cylinder is blocked and limited by the limit block to prevent the cylinder from moving downward, thus avoiding the problem of failure of the RF connector body test caused by the misalignment of the cone surface 1 and the cone surface 2.

In the process of manually inserting the RF connector body into the socket, friction is generated between the RF connector body and the friction block, causing the RF connector body to slide down in a damped manner, greatly reducing the movement speed of the RF connector body, thereby effectively avoiding the problem of further bending the pin part. At the same time, the RF connector body is clamped by the fixing block, further avoiding the problem of bending the pin part. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0018] Example 1 An intelligent test device for the connection performance of a radio frequency connector, such as Figure 1-Figure 6As shown, it includes a tester 1 and a socket 2; four sockets 2 are installed on the tester 1, and the socket 2 is set to be made of plastic material; it also includes a connecting block 3, a cylinder 4, a spring 5 and a round rod 6; each socket 2 is fixedly connected to a connecting block 3; each connecting block 3 is slidably connected to three cylinders 4; each cylinder 4 is fixedly connected to a spring 5, and the other end of the spring 5 is fixedly connected to the corresponding socket 2; each socket 2 is fixedly connected to three round rods 6, the round rod 6 is connected to the tester 1, and the round rod 6 is slidably connected to the corresponding cylinder 4; each cylinder 4 is provided with a conical surface part 92; each round rod 6 is provided with a conical surface part 93, and the conical surface part 93 and the corresponding conical surface part 92 are located on the same conical surface.

[0019] It also includes a limiting component; the limiting component is connected to the socket 2; the limiting component includes a limiting block 201 and a linkage unit; each socket 2 is slidably connected to two limiting blocks 201, and the limiting blocks 201 are located at the lower side of the corresponding cylinder 4, and the cylinder 4 is supported and limited by the limiting blocks 201; the socket 2 is connected to a linkage unit.

[0020] The linkage unit includes a linkage block 202 and a spring 203; each limit block 201 is bolted with at least two linkage blocks 202; each linkage block 202 and the corresponding socket 2 are commonly fixedly connected with a spring 203, and the spring 203 is set to an alloy material; four inclined portions 94 are set on the RF connector body 7.

[0021] The linkage block 202 is configured to be made of a non-conductive wear-resistant material, so as to increase the service life of the linkage block 202 and reduce the risk of short circuit.

[0022] During the test, the RF connector body 7 is manually inserted downward into the socket 2 until the RF connector body 7 just contacts the cylinder 4. During this process, if the pin portion 91 is not bent, the lower end of the pin portion 91 is directly inserted downward into the round rod 6. If the pin portion 91 is bent, the pin portion 91 first contacts the conical surface portion 1 92 during the downward movement. The RF connector body 7 continues to move downward, so that the conical surface portion 1 92 guides the lower end of the pin portion 91, so that the lower end of the pin portion 91 moves to the conical surface portion 2 93. The RF connector body 7 continues to move downward, so that the conical surface portion 2 93 guides the lower end of the pin portion 91, so that the lower end of the pin portion 91 is inserted into the round rod 6, so that the pin portion 91 is electrically connected to the round rod 6, and then the RF connector body 7 is tested by the tester 1.

[0023] In order to allow the pin portion 91 of various bending angles to be smoothly inserted into the conical surface portion 92, the diameter of the opening on the conical surface portion 92 should be set large enough, and in order to ensure the guiding effect of the conical surface portion 92 on the pin portion 91, the slope of the conical surface portion 92 should also be set large enough, which results in a relatively large height of the conical surface portion 92 and a relatively small length of the pin portion 91, resulting in that after the pin portion 91 is inserted into the round rod 6, only a very small part of the pin portion 91 is in contact with the round rod 6, resulting in low connection stability, and further resulting in low stability of the test operation. Therefore, when the RF connector body 7 is in contact with the cylinder 4 and the lower end of the pin portion 91 is inserted into the round rod 6, the RF connector body 7 is manually pushed downward until the RF connector body 7 is tightly inserted into the socket 2. During this process, the RF connector body 7 pushes the cylinder 4 downward and exerts pressure on the spring. 5 is compressed, so that the pin portion 91 moves downward and is deeply inserted into the round rod 6, so that the pin portion 91 is stably contacted with the round rod 6, which is beneficial to improving the stability of the test operation. When in use, the RF connector body 7 only needs to be inserted into the socket 2, and the cylinder 4 and the round rod 6 can be matched to automatically test the RF connector body 7 with the pin portion 91 bent. Compared with the existing equipment, the present equipment does not need to perform pin bending detection and pin bending correction operations, which reduces the working steps and is beneficial to improving efficiency. At the same time, through the cooperation of the cylinder 4 and the spring 5, after the cylinder 4 guides the pin portion 91, it can automatically avoid downward, so that the relatively short pin portion 91 can still be stably inserted into the round rod 6 to ensure the stability of the test operation of the RF connector body 7. At the same time, the avoidance process of the cylinder 4 is completed in conjunction with the insertion of the RF connector body 7, and the structure is ingenious.

[0024] When the pin portion 91 contacts with the conical surface portion 1 92 and the RF connector body 7 continues to move downward, the pin portion 91 will generate a downward thrust on the cylinder 4. If the thrust is too large, the pin portion 91 will push the cylinder 4 to move downward and compress the spring 1 5, so that the conical surface portion 1 92 and the conical surface portion 2 93 are offset, which makes it impossible to guide the pin portion 91 into the round rod 6, thereby causing the test of the RF connector body 7 to fail. Therefore, during the process of the conical surface portion 1 92 guiding the pin portion 91, the cylinder 4 is blocked and limited by the limit block 201 to prevent the cylinder 4 from moving downward, thereby avoiding the problem of the test failure of the RF connector body 7 caused by the offset between the conical surface portion 1 92 and the conical surface portion 2 93. When the lower end of the pin portion 91 is inserted into the round rod 6, the inclined surface portion 94 on the RF connector body 7 just contacts with the linkage block 202, and a certain gap is formed between the RF connector body 7 and the cylinder 4. The RF connector body 7 is manually pushed downward until the RF connector body 7 is tightly inserted into the socket 2. During this process, the RF connector body 7 pushes the linkage block 202 to move through the inclined surface 94 and compresses the spring 203, so that the linkage block 202 drives the limit block 201 away from the bottom of the cylinder 4, so that the limit block 201 stops blocking and limiting the cylinder 4, and then the RF connector body 7 pushes the cylinder 4 downward to make the pin portion 91 stably and deeply inserted into the round rod 6, and then the test operation is performed. When in use, the limit block 201 blocks and limits the cylinder 4 to prevent the cylinder 4 from moving downward, thereby avoiding the problem of test failure of the RF connector body 7 caused by the misalignment of the conical surface 1 92 and the conical surface 2 93, and the limit block 201 can be automatically unlocked as the RF connector body 7 is inserted, without the need to set up an additional electric drive component, and the structure is ingenious.

[0025] Example 2 On the basis of Example 1, Figure 1 , Figure 5 and Figure 6 As shown, it also includes an auxiliary component; the cylinder 4 is connected to the auxiliary component; the auxiliary component includes a ring 204, a spring three 205, a pressure sensor 206 and a buzzer 207; each cylinder 4 is slidably connected to a ring 204; two springs three 205 are fixedly connected between each ring 204 and the corresponding cylinder 4, and the spring three 205 is set to an alloy material; each ring 204 is fixedly connected to the corresponding cylinder 4 with a pressure sensor 206, and the pressure sensor 206 is used to monitor whether the ring 204 is under force; a buzzer 207 is installed on the tester 1.

[0026] The conical surface part 1 92 cannot guide the pin part 91 with an excessively large bending angle. Therefore, when the RF connector body 7 is manually inserted into the socket 2, the lower end of the pin part 91 with an excessively large bending angle will exceed the range covered by the opening on the conical surface part 1 92, that is, the lower end of the pin part 91 with an excessively large bending angle will contact the ring 204. When the RF connector body 7 continues to move downward, the pin part 91 pushes the ring 204 to move downward and compresses the spring 3 205. The downward movement of the ring 204 compresses the pressure sensor 206, so that the pressure sensor 206 detects the pressure. At this time, the pressure sensor 206 detects the pressure. The force sensor 206 transmits a signal to the buzzer 207, causing the buzzer 207 to sound an alarm. After hearing the alarm, the human stops inserting the RF connector body 7 and pulls out the RF connector body 7 to avoid the tester 1 from making a misjudgment when testing an unconnected RF connector body 7. When in use, through the cooperation of the ring 204 and the pressure sensor 206, during the process of manually inserting the RF connector body 7, the RF connector body 7 with a pin portion 91 having an excessively large bending angle can be automatically screened out to avoid the tester 1 from making a misjudgment when testing an unconnected RF connector body 7.

[0027] Example 3 On the basis of Example 2, Figure 7 As shown, friction blocks 208 are also included; four friction blocks 208 are fixedly connected to each socket 2. When the RF connector body 7 is inserted into the socket 2, friction resistance is generated with the friction blocks 208, so that the RF connector body 7 is slowly inserted into the socket 2.

[0028] The friction block 208 is detachably connected to the corresponding socket 2 to facilitate replacement of a damaged friction block 208 .

[0029] It also includes a clamping assembly; the clamping assembly is connected to the socket 2; the clamping assembly includes a fixed block 209, a spring four 2010 and a pipe 2011; each socket 2 is sealed and slidably connected to two fixed blocks 209; two spring four 2010 are fixedly connected between each fixed block 209 and the corresponding socket 2; and two pipes 2011 are fixedly connected to each socket 2.

[0030] The fixing block 209 is provided with a plurality of grooves for increasing friction.

[0031] The opening of the socket 2 is provided with a chamfer, so that the RF connector body 7 is easier to insert into the socket 2 .

[0032] When the pin portion 91 passes through the ring 204 to squeeze the pressure sensor 206, if the speed of manually inserting the RF connector body 7 is too fast, the RF connector body 7 will continue to move downward for a certain distance during the period from when the pressure sensor 206 detects the pressure to when the human hears the alarm, thereby further bending the pin portion 91 and increasing the difficulty of repairing the pin portion 91. Therefore, a friction block 208 is provided on the inner wall of the socket 2. During the process of manually inserting the RF connector body 7 into the socket 2, friction is generated between the RF connector body 7 and the friction block 208, thereby causing the RF connector body 7 to slide down in a damped manner, greatly reducing the movement speed of the RF connector body 7, thereby effectively avoiding the problem of further bending the pin portion 91.

[0033] First, the external air pump is manually connected to the pipe 2011. When the pressure sensor 206 detects the pressure, it controls the external air pump to deliver air to the pipe 2011. The air flows into the cavity where the spring four 2010 is located through the pipe 2011, thereby pushing the fixed block 209 to move through the air pressure and stretching the spring four 2010, so that the fixed block 209 clamps the RF connector body 7, further avoiding the problem of bending the pin part 91 due to manual blind pressure.
