Description

Technical Field

[0001] This invention relates to the field of electronic technology, and more specifically, to a blind mating alignment structure for waveguide connections. Background Technology

[0002] Two identical waveguides are typically connected at their transmission ports using a flange structure with screws. The screws secure the flange connection at the ports and also ensure the alignment of the waveguide ports at the flange. Figure 4 As shown, waveguide one and waveguide two are connected, fixed and aligned by tightening their flanges with screws. Waveguide one and waveguide two use four screws to align and assemble the two waveguide ports. However, screw assembly is not conducive to the rapid assembly of components, nor is it conducive to improving the alignment accuracy of the waveguide ports.

[0003] This connection method has two problems: First, using screws to fix the waveguide flange results in low assembly accuracy and efficiency, and blind mating is not possible; second, the waveguide transmission port is aligned with a pin on one side of the flange, which makes the alignment accuracy of the waveguide port connected by the flange poor, especially in the millimeter wave band, which can easily lead to the deterioration of the standing wave at the connector and high transmission loss. This method can barely achieve blind mating, but because the pin is very thin and short, if the force is not properly controlled during blind mating, the pin can easily be bent or even broken, causing damage to the waveguide.

[0004] In summary, the traditional approach mainly involves waveguide interconnection, but it cannot effectively achieve blind waveguide insertion. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a blind mating alignment structure for waveguide connection; which can effectively improve the blind mating alignment accuracy of waveguide, realize the efficient completion of interconnection and assembly of high power component waveguide input or output ports with sub-units, systems, etc., and enable screwless installation operation.

[0006] The solution adopted by this invention to solve the technical problem is:

[0007] A blind mating structure for waveguide connection includes a male connector and a female connector that mates with the male connector.

[0008] A groove is provided at one end of the female connector, and the male connector is inserted into the groove.

[0009] A blind hole is provided in the groove, and a guide pin assembly that mates with the blind hole is provided on the male connector.

[0010] In some possible implementations,

[0011] The male connector includes a flange connected to one end of the waveguide, and the guide pin assembly is located on the side of the flange away from the waveguide.

[0012] In some possible implementations,

[0013] The connector female includes a second flange that is connected to one end of another set of waveguides; the blind hole is located on the side of the first flange away from the waveguide; the first flange is inserted into the groove.

[0014] In some possible implementations,

[0015] The guide pin assembly includes a fine guide pin and a coarse guide pin arranged axially along the male connector and mounted on flange one; the diameter of the fine guide pin is smaller than the diameter of the coarse guide pin.

[0016] In some possible implementations,

[0017] The length of the thin guide pin along its axial direction is less than the length of the thick guide pin along its axial direction.

[0018] In some possible implementations,

[0019] Both the thin and thick guide pins have a frustoconical shape at the end furthest from the waveguide.

[0020] In some possible implementations,

[0021] The blind hole includes a small positioning hole that works with the thin guide pin and communicates with the groove, and a large positioning hole that works with the thick guide pin and communicates with the groove.

[0022] In some possible implementations,

[0023] Both the fine guide pins and the coarse guide pins are in two sets.

[0024] In some possible implementations,

[0025] The two sets of thin guide pins are arranged axially symmetrically, and the two sets of coarse guide pins are arranged centrally symmetrically.

[0026] In some possible implementations,

[0027] The machining accuracy of the fine guide pin is better than that of the coarse guide pin.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] This invention effectively achieves waveguide connection through the arrangement of flange one, flange two, and guide pin assembly;

[0030] This invention improves the high-precision blind insertion of waveguides by setting a coarse guide pin, a fine guide pin, a large positioning hole that works with the coarse guide pin, a small positioning hole that works with the fine guide pin, and setting the free ends of the coarse and fine guide pins into a frustum shape. During assembly, low-precision positioning can be achieved first by using the guide pins, and then high-precision positioning can be achieved by using the fine guide pins.

[0031] This invention has a simple structure and is highly practical. Compared with existing technologies, it does not require the use of screws for operation. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] The present invention will now be described in detail;

[0039] like Figures 1-3 As shown, a blind mating structure for waveguide connection includes a male connector 10 connected to a set of waveguides and a female connector 20 that is mated with the male connector 10 and connected to another set of waveguides.

[0040] A groove 21 is provided at one end of the female connector 20, and the male connector 10 is inserted into the groove 21.

[0041] A blind hole is provided in the groove 21, and a guide pin assembly 3 is provided on the male connector 10 to cooperate with the blind hole.

[0042] The present invention achieves high-precision blind insertion of the waveguide by inserting the male connector 10 into the groove 21 and by cooperating with the guide pin assembly 3 and the blind hole;

[0043] In some possible implementations, in order to effectively achieve waveguide connection and high-precision positioning, thereby achieving high-precision blind insertion;

[0044] The male connector 10 includes a flange 1 that is connected to one end of a set of waveguides and is inserted into a groove 21. The guide pin assembly 3 is located on the side of the flange 1 away from the set of waveguides.

[0045] During assembly, the guide pin assembly 3 is engaged with the blind hole, and the flange 1 is inserted into the groove 21. The guide pin assembly 3 and the blind hole will achieve the positioning accuracy of the connector male head 10 and the connector female head 20.

[0046] In some possible implementations,

[0047] The connector female head 20 includes a flange 2 connected to one end of another set of waveguides; the blind hole is located on the side of the flange 1 away from the set of waveguides; the flange 1 is inserted into the groove 21.

[0048] In some possible implementations, in order to enable high-precision blind insertion alignment of the two sets of waveguides;

[0049] The guide pin assembly 3 includes a thin guide pin 32 and a coarse guide pin 31 arranged axially along the male connector 10 and mounted on the flange 1. The thin guide pin 32 and the coarse guide pin 31 are arranged in parallel. The diameter of the thin guide pin 32 is smaller than the diameter of the coarse guide pin 31.

[0050] The length of the thin guide pin 32 along its axial direction is less than the length of the thick guide pin 31 along its axial direction.

[0051] The ends (free ends) of both the coarse guide pin 31 and the fine guide pin 32 that are furthest from the waveguide are frustoconical.

[0052] The machining accuracy of the fine guide pin 32 is better than that of the coarse guide pin 31.

[0053] By setting different lengths, diameters, and machining precision, the fine guide pin 32 and the coarse guide pin 31 effectively enable the male connector 10 and the female connector 20 to achieve two-level positioning, thus completing the high-precision blind mating of the waveguide.

[0054] In some possible implementations,

[0055] The blind hole includes a small positioning hole 23 that works in conjunction with the thin guide pin 32 and communicates with the groove 21, and a large positioning hole 22 that works in conjunction with the thick guide pin 31 and communicates with the groove 21.

[0056] In some possible implementations,

[0057] Both the fine guide pin 32 and the coarse guide pin 31 are in two sets.

[0058] In some possible implementations,

[0059] The two sets of thin guide pins 32 are arranged axially symmetrically, and the two sets of coarse guide pins 31 are arranged centrally symmetrically.

[0060] The flange 1 is provided with two sets of coarse guide pins 31 and fine guide pins 32. Furthermore, the coarse guide pins 31 and fine guide pins 32 are installed with the flange 1 by plugging in. That is, the flange 1 is also provided with positioning hole 1 corresponding to the large positioning hole 22 and positioning hole 22 corresponding to the small positioning hole 23.

[0061] There are two large positioning holes 22 and two small positioning holes 23 machined on flange 2, which correspond one-to-one with the coarse guide pin 31 and the fine guide pin 32.

[0062] The length of the coarse guide pin 31 is longer than that of the fine guide pin 32; furthermore, the machining accuracy of the fine guide pin 32 should be significantly better than that of the coarse guide pin 31; the free ends of the coarse guide pin 31 and the fine guide pin 32 are frustoconical, that is, they are chamfered cones; this setting enables rapid positioning during assembly.

[0063] During the blind mating process between the male connector 10 and the female connector 20, since the length of the coarse guide pin 31 is longer than that of the fine guide pin 32, the coarse guide pin 31 is used for low-precision alignment first. After the low-precision alignment is completed, the fine guide pin 32 is aligned with the small positioning hole 23 for high-precision alignment. The male connector 10 and the female connector 20 are positioned by two levels of guide pins, thus completing the high-precision blind mating of the waveguide.

[0064] Example 1:

[0065] like Figures 1-3As shown, this invention proposes a structure to improve the blind insertion alignment accuracy of waveguides. This technology uses two-stage guide pins (fine guide pin 32 and coarse guide pin 31) to blindly insert and align two sets of waveguide ports.

[0066] A Ka-band BJ320 waveguide blind mating connector has a coarse guide pin 31 with a length of 5.8mm, a diameter of 1mm, and a tolerance of -0.03mm, and a fine guide pin 32 with a length of 4.3mm, a diameter of 0.5mm, and a tolerance of -0.01mm; the alignment accuracy of this waveguide blind mating connector can reach 0.01mm.

[0067] A set of guide positioning components consisting of a set of coarse guide pins 31 and a set of fine guide pins 32 arranged on the same side is centrally symmetrically arranged with another set of guide positioning components consisting of a set of coarse guide pins 31 and a set of fine guide pins 32, and located on both sides of flange 1.

[0068] This invention is not limited to the specific embodiments described above. The invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
