Description

Technical Field

[0001] This utility model relates to the field of precision filter manufacturing, specifically a tooling for inspecting the position accuracy of a filter quick-connect connector. Background Technology

[0002] With the upgrading and iteration of wireless communication technology, especially the large-scale application of Massive MIMO technology in 5G communication, the integration of base station filters is getting higher and higher, and the number of channels in each communication filter module is increasing. In the previous generation of mobile communication filter modules, the number of connectors was usually less than 8. In 5G base station equipment filters, the number of connectors has increased dramatically, ranging from 16 to 64. With the addition of the signal detection function of the filter antenna port, the number of connectors is even greater. In order to improve the installation and docking efficiency of filter modules and other active modules in the base station, connectors have gradually evolved from threaded or screw connections to plug-in connections, also known as quick plugs.

[0003] Currently, the connector position in the filter production process is too large to be detected quickly. Inspecting the connector position accuracy in the filter module relies heavily on coordinate measuring machine (CMM) testing. However, CMM testing is expensive and only suitable for laboratory testing, not for mass production. The simultaneous alignment of multiple quick-connect connectors on the same plane with connectors in other modules places higher demands on the position accuracy of connectors on the filter module. Previously, with 8 connectors, the position accuracy could be controlled within ±0.2, and the connector mating accuracy was sufficient. Now, with up to 32 connectors being mated simultaneously, the relative position superposition error of the connectors increases exponentially. If the relative position deviation between any two connectors is too large, or if the system position error between several connectors exceeds the tolerance, problems will occur in the mating of the filter module and the active module.

[0004] Furthermore, repeated insertions can easily lead to friction damage, and the mating insertion structure cannot be easily limited and fixed, which can easily cause synchronous sliding of the mating insertion structure, affecting the convenience and practicality of subsequent insertion testing. Therefore, it is necessary to design a filter quick-connect connector position accuracy inspection fixture to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a tooling for inspecting the position of a filter quick-connect connector, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixture for inspecting the position of a filter quick-connect connector, comprising a fixture plate, three sets of irregularly arranged fixing holes on the surface of the fixture plate, a sleeve movably placed inside the fixing holes, a plurality of support columns fixedly connected to the bottom of the fixture plate, a first detection pin movably placed inside one set of the sleeve, a second detection pin movably placed inside one set of the sleeve, a positioning pin placed inside one set of the sleeve, and a limiting member for fixing the sleeve installed between the sleeve and the fixing holes.

[0007] Preferably, the limiting member includes four fixing cavities formed around the fixing hole, an elastic frame is fixedly connected to one side of the fixing cavity, a sliding plate for installing a locking ball is fixedly connected to one side of the elastic frame, and four locking grooves arranged in a circle are respectively formed around the sleeve, and the sliding plate is slidably connected to the fixing cavity.

[0008] Preferably, two positioning blocks are fixedly connected to the outer side of the first detection pin, the outer side of the second detection pin, and the outer side of the positioning pin, and two positioning grooves are formed on the inner side of the sleeve near the top.

[0009] Preferably, the top of the insert is fixedly connected with an anti-detachment part.

[0010] Preferably, the tooling plate has two handles bolted to its surface.

[0011] Preferably, the bottom of the anti-detachment part is fixedly connected to two positioning posts, which are inserted around the fixing holes.

[0012] Preferably, two spring pieces are fixedly connected to the inner side of the elastic frame, and the two spring pieces are fixedly connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The tooling plate can measure the position of all connectors in a single use, clearly eliminating connectors with poor position. Compared with the previous coordinate measuring machine, the efficiency is greatly improved, the measurement results are stable and reliable, the tooling positioning accuracy is high, the sleeve surface is chrome plated and fully hardened, providing good wear resistance while ensuring hardness, ensuring that the durability of the tooling can withstand the requirements in subsequent long-term use. The radial fit tolerance of the sleeve is ±0.03mm. The sleeve is press-fitted to the main body of the tooling plate with interference fit. During the use of the tooling plate, the sleeve provides support and positioning function for the first detection pin, the second detection pin, and the positioning pin.

[0015] 2. Both the locking ball and the locking groove have arc-shaped cross sections. The elastic frame inside the fixed cavity can squeeze and push the sliding plate. The sliding plate pushes the locking ball into the locking groove to limit and fix the insert, increasing the stability of the insert and the tooling plate. This prevents the insert from being dislodged from the fixing hole when the first detection pin, the second detection pin, and the positioning pin are inserted and slid. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please refer to Figures 1-5As shown, this utility model provides a fixture for inspecting the position of a filter quick-connect connector, including a fixture plate 1. The surface of the fixture plate 1 has three sets of irregularly arranged fixing holes 2. A sleeve 3 is movably placed inside the fixing holes 2. Multiple support columns 4 are fixedly connected to the bottom of the fixture plate 1. A first detection pin 5 is movably placed inside one set of sleeves 3. A second detection pin 6 is movably placed inside one set of sleeves 3. A positioning pin 7 is placed inside one set of sleeves 3. A limiting member for fixing the sleeve 3 is installed between the sleeve 3 and the fixing holes 2. Two handles 16 are bolted to the surface of the fixture plate 1.

[0025] It should be added that the tooling plate 1 can measure the position of all connectors in one use, and clearly reject connectors with poor position. Compared with the previous coordinate measuring machine, the efficiency is greatly improved, the measurement results are stable and reliable, the tooling positioning accuracy is high, the sleeve 3 is chrome plated and hardened throughout, which can provide good wear resistance while ensuring hardness, and ensure that the durability of the tooling can withstand the requirements in the subsequent long-term use. The radial fit tolerance of the sleeve 3 is ±0.03mm. The sleeve 3 is pressed and riveted to the main body of the tooling plate 1 with an interference fit. During the use of the tooling plate 1, the sleeve 3 provides support and positioning functions for the first detection pin 5, the second detection pin 6, and the positioning pin 7.

[0026] Furthermore, the fixture plate 1 is CNC machined from aluminum alloy, and the surface is treated with conductive oxidation to prevent corrosion from affecting the accuracy of the fixture surface. The fixing hole 2 on the top of the fixture plate 1 mates with the insert 3. The support columns 4 are evenly distributed and installed at the bottom of the fixture plate 1 to provide support for the fixture plate 1 and ensure that the main body of the fixture remains horizontal during use. The function of the first detection pin 5 and the second detection pin 6 is to check the position of the ZSMP connector and POWER-SMP connector of the filter product. During the test, if the first detection pin 5 and the second detection pin 6 can be pressed down smoothly and make contact with the upper end face of the insert 3 without gaps, then the position of the ZSMP connector and POWER-SMP connector is qualified. The function of the positioning pin 7 is to accurately position the main body of the fixture plate 1. Only when the positioning pin 7 accurately positions the main body can the subsequent testing work be carried out. The function of the handle 16 is to provide a grip for the entire fixture.

[0027] Specifically, the limiting component includes four fixed cavities 8 opened around the fixed hole 2. An elastic frame 9 is fixedly connected to one side of the fixed cavity 8. A sliding plate 11 for installing a locking ball 10 is fixedly connected to one side of the elastic frame 9. Four locking grooves 12 arranged in a circle are opened around the sleeve 3. The sliding plate 11 is slidably connected to the fixed cavity 8. Two spring pieces 18 are fixedly connected to the inner side of the elastic frame 9. The two spring pieces 18 are fixedly connected.

[0028] The locking ball 10 and the locking groove 12 are both arc-shaped. The elastic frame 9 in the fixed cavity 8 can squeeze and push the sliding plate 11. The two spring pieces 18 can support the elastic frame 9 and increase the expansion strength of the elastic frame 9. The sliding plate 11 pushes the locking ball 10 into the locking groove 12 to limit and fix the insert 3, increasing the stability of the insert 3 and the tooling plate 1, and preventing the insert 3 from being dislodged from the fixing hole 2 when the first detection pin 5, the second detection pin 6, and the positioning pin 7 are inserted and slid.

[0029] More specifically, two positioning blocks 13 are fixedly connected to the outer side of the first detection pin 5, the outer side of the second detection pin 6, and the outer side of the positioning pin 7. Two positioning grooves 14 are opened on the inner side of the sleeve 3 near the top. An anti-detachment part 15 is fixedly connected to the top of the sleeve 3. Two positioning posts 17 are fixedly connected to the bottom of the anti-detachment part 15. The positioning posts 17 are inserted around the fixing hole 2.

[0030] Furthermore, when the first detection pin 5, the second detection pin 6, and the positioning pin 7 are inserted into the sleeve 3, the two positioning blocks 13 are inserted into the positioning groove 14 to limit the first detection pin 5, the second detection pin 6, and the positioning pin 7. The anti-dislodgement part 15 can prevent the sleeve 3 from entering the fixing hole 2. The positioning post 17 at the bottom of the anti-dislodgement part 15 is inserted around the fixing hole 2 on the surface of the tooling plate 1. The positioning post 17 is used to position the sleeve 3, thereby improving the convenience and stability of positioning the first detection pin 5, the second detection pin 6, the positioning pin 7, and the sleeve 3.

[0031] Working principle: First, the tooling plate 1 is placed by using the handle 16. Multiple support columns 4 provide horizontal support for the tooling plate 1. Then, the insert 3 is inserted into the fixing hole 2. The elastic frame 9 in the fixing cavity 8 squeezes and pushes the sliding plate 11. At the same time, two spring pieces 18 support the elastic frame 9. Then, the sliding plate 11 pushes the locking ball 10 into the locking groove 12 to limit and fix the insert 3. At this time, the anti-detachment part 15 at the top of the insert 3 is in contact with the surface of the tooling plate 1, and the positioning column 17 at the bottom of the anti-detachment part 15 is inserted into the surface of the tooling plate 1.

[0032] During the test, if the first detection pin 5 and the second detection pin 6 are pressed down smoothly and there is no gap in contact with the upper surface of the sleeve 3, then the positional accuracy test is qualified.
