[0023] Reference Figure 1 , an easy-to-assemble, high-reliability millimeter wave adapter, the adapter includes a front shell 1, a rear shell 2, a transfer pin assembly 3, a first gasket 4, and a second gasket 5. The first gasket 4 and the second gasket 5 are coaxially arranged on the outer periphery of the transfer pin assembly 3, and the transfer pin assembly 3 is axially installed in the front shell 1 and the rear shell 2. The front shell 1 and the rear shell 2 are connected by threads, and the transfer pin assembly 3, the first gasket 4 and the second gasket 5 are axially limited in the front shell 1 and the rear shell 2.

[0024] Reference Figure 2 、 Figure 8 and Figure 9 The adapter pin assembly 3 includes an adapter pin 3-1, an insulator 3-2 and a fixing ring 3-3. The adapter pin 3-1 is axially placed in the insulator 3-2, and the annular body is sleeved on the outer periphery of the insulator 3-2 to fix the adapter pin 3-1 and the insulator 3-2. Figure 1 The first washer 4 and the second washer 5 are respectively located on the left and right sides of the fixing ring 3-3.

[0025] Reference Figure 3-Figure 7 The insulator 3-2 includes an upper insulator 3-2-1 and a lower insulator 3-2-2. The insulator 3-2 is in the shape of a hollow cylinder and is formed by buckling the upper insulator 3-2-1 and the lower insulator 3-2-2. The upper insulator 3-2-1 and the lower insulator 3-2-2 are two parts obtained by obliquely cutting the hollow cylinder along the axial direction and passing through the hollow cylinder. The intersection of the oblique cut surface and the upper bottom surface and the lower bottom surface of the hollow cylinder is two parallel and symmetrical first non-diameter chords 3-2-1-1 and second non-diameter chords 3-2-2-1 along the central axis. The axial projection shape of the upper insulator 3-2-1 and the lower insulator 3-2-2 is a trapezoid with reverse symmetry.

[0026] Reference Figure 2The fixing ring 3-3 is in the shape of a circular ring, and the left and right end surfaces of the inner hole of the circular ring have chamfers, and the circular ring and the insulator are interference fit.

[0027] Reference Figure 1 The first gasket 4 and the second gasket 5 are both in the shape of a ring.

[0028] The butt end of the front housing 1 is provided with an external thread on the outside, and a stepped hole consisting of a larger diameter inner hole 1-1 and a smaller diameter inner hole 1-2 is provided on the inside of the butt end. The first washer 4 and the second washer 5 are both placed in the larger diameter inner hole 1-1 of the stepped hole, and the inner diameter of the larger diameter inner hole 1-1 matches the outer diameters of the first washer 4 and the second washer 5. The front end face of the first washer 4 contacts the step surface of the stepped hole, and the end face of the second washer 5 is flush with the end face of the larger diameter inner hole 1-1, and the inside of the rear housing 2 A first annular groove 2-1, a second annular groove 2-2 and a third annular groove 2-3 are provided at the same time. The inner diameter of the first annular groove 2-1 is larger than the inner diameter of the second annular groove 2-2. An internal thread matching the external thread is provided on the inner circumferential surface of the first annular groove 2-1. When the front shell 1 and the rear shell 2 are connected in place, the end surface of the docking end of the front shell 1 and the end surface of the second gasket 5 are in contact with the step surface formed by the first annular groove 2-1 and the second annular groove 2-2 of the rear shell 2, thereby realizing axial limitation of the first gasket 4, the second gasket 5 and the adapter needle assembly 3.

[0029] During assembly, first assemble the adapter pin assembly, and buckle the upper insulator 3-2-1 and the lower insulator 3-2-2 on the outer periphery of the adapter pin 3-1 to form an insulator. The insulator is in the shape of a hollow cylinder, and the adapter pin 3-1 is axially passed through the hollow cylindrical shape after buckling. Then the insulator 3-2 is sent into the fixing ring 3-3 together with the adapter pin 3-1. The trapezoidal cross-sectional structure of the upper insulator 3-2-1 and the lower insulator 3-2-2 forms a staggered tooth mechanism when they are paired, which has a stopping function when the fixing ring 3-3 is interference fit, thereby ensuring the relative position of the parts; at the same time, the left and right end faces of the inner hole of the fixing ring 3-3 have chamfers, which not only facilitates the assembly of the insulator 3-2 and the annular body 3-3, but also plays a role in compensating the characteristic impedance.

[0030] Then, clamp the first washer 4 and the second washer 5 on both sides of the fixing ring 3-3 of the adapter pin assembly 3 respectively, and then insert them into the front housing 1 in sequence. The rear housing 2 and the front housing 1 are connected and locked by internal and external threads. The first washer 4, the second washer 5, the front housing 1, and the rear housing 2 are coaxial with each other after assembly.

[0031] After the front housing 1 and the rear housing 2 are screwed into place, they can play an axial limiting role on the first washer 4, the second washer 5, and the component adapter pin assembly 3, so that the structure can meet the requirements of high impact, strong vibration and other environments.

[0032] This type of high-frequency transfer pin assembly has a simple processing technology and is easy to assemble. It can be used in conjunction with a high-frequency coaxial adapter to achieve the transfer transmission function of high-frequency signals.

The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
