Description

Technical Field

[0001] This invention belongs to the field of blind mating of coaxial connectors, specifically relating to a method, apparatus and working method of double-ended radial offset. Background Technology

[0002] The radial offset tolerance of coaxial connectors not only affects the positional accuracy requirements of product installation but also the reliability of the connection. To test the radial tolerance of connectors, a radial offset test is performed. Currently, the most widely used testing method is manual offset. Typically, the connectors of two coaxial connectors are connected by a connector. When radial offset of the connector within the connector's joint is required, a common method is to offset the two coaxial connectors vertically, thus achieving radial offset. This method is manual, and its drawbacks include the inability to accurately identify and control the offset amount, and the potential for both coaxial connectors and the connector to rotate together, thus failing to achieve effective radial offset. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a method, apparatus and working method for double-ended radial offset, which can offset the connector in a simple and efficient manner, and the offset amount is controllable and readable.

[0004] To achieve the above objective, a two-end radial offset method includes the following steps:

[0005] Move the first coaxial connector and the second coaxial connector upward and downward respectively, so that the connector between the first coaxial connector and the second coaxial connector is offset within the connection port of the first coaxial connector and the second coaxial connector.

[0006] Keeping the first and second coaxial connectors parallel, the offset angle and radial offset of the connectors are obtained based on the length of the connectors and the external dimensions of the first and second coaxial connectors.

[0007] A double-ended radial offset device includes a fixing member. A left boss is provided on the top left side of the fixing member, and a right boss is provided on the bottom right side of the fixing member. The left boss and the right boss are arranged in parallel to each other, thereby obtaining the radial offset amount and the radial offset amount of the connector.

[0008] The left boss is used to limit the position of the first coaxial connector.

[0009] The left boss contacts the outer diameter axial surface of the first coaxial connector and the end face of the first coaxial connector's connection port.

[0010] The right-side boss is used for the second coaxial connector.

[0011] The right-side boss contacts the outer diameter axial surface of the second coaxial connector and the end face of the connection port of the second coaxial connector.

[0012] A method for operating a double-ended radial offset device includes the following steps:

[0013] The fastener is placed between the first coaxial connector and the second coaxial connector, so that the left and right bosses of the fastener contact the first and second coaxial connectors respectively, thereby keeping the first and second coaxial connectors parallel and offsetting the connectors.

[0014] The left boss contacts the outer diameter axial surface of the first coaxial connector and the end face of the first coaxial connector's connection port, thus completing the axial and radial positioning of the first coaxial connector.

[0015] The right-side boss contacts the outer diameter axial surface of the second coaxial connector and the end face of the connection port of the second coaxial connector, thus completing the axial and radial positioning of the second coaxial connector.

[0016] The radial offset angle of the connector is calculated as follows:

[0017]

[0018] Where 'a' is the offset angle of the connector, 'L1' is the length of the connector, 'L2' is the size of the limiting platform of the fixing member, and 'L3' is the outer diameter of the connection port of the first or second coaxial connector.

[0019] The radial offset of the connector is calculated as follows:

[0020] X = L3 - L2

[0021] Where X is the radial offset of the connector, L2 is the size of the limiting platform of the fixing member, and L3 is the outer diameter of the connection port of the first coaxial connector or the second coaxial connector.

[0022] Compared with the prior art, the present invention moves the first coaxial connector and the second coaxial connector upward and downward respectively, so that the connector between the first coaxial connector and the second coaxial connector is offset within the connection port of the first coaxial connector and the second coaxial connector, thereby obtaining the offset angle and radial offset of the connector. The present invention is simple to operate and the radial offset is controllable, which can quickly and accurately identify the offset of the connector.

[0023] The device of the present invention can be assisted in positioning by the right-side boss and the left-side boss, so that the first coaxial connector and the second coaxial connector remain parallel at all times when moving, thereby making the test results more accurate and stable.

[0033] The invention will now be further described with reference to the accompanying drawings.

[0034] See Figure 1 , Figure 2 and Figure 3 A two-ended radial offset method includes the following steps:

[0035] Move the first coaxial connector 1 and the second coaxial connector 2 upward and downward respectively, so that the connector between the first coaxial connector 1 and the second coaxial connector 2 is offset within the connection port of the first coaxial connector 1 and the second coaxial connector 2.

[0036] Keeping the first coaxial connector 1 and the second coaxial connector 2 parallel, the offset angle and radial offset of the connector 3 are obtained based on the length and diameter of the connector 3, as well as the inner and outer diameters of the connection ports of the first coaxial connector 1 and the second coaxial connector 2.

[0037] The method for calculating the offset angle of connector 3 is as follows:

[0038]

[0039] Where a is the offset angle of connector 3, L2 is the size of the limiting platform of fixing member 4, L3 is the outer diameter of the connection port of the first coaxial connector 1 or the second coaxial connector 2, and L2 < L3.

[0040] The radial offset of connector 3 is calculated as follows:

[0041] X = L3 - L2

[0042] Where X is the radial offset of connector 3, L1 is the length of connector 3, and a is the offset angle of connector 3.

[0043] See Figure 1 and Figure 4 A double-ended radial offset device includes a fixing member 4. A left boss 4-1 is provided on the top left side of the fixing member 4, and a right boss 4-2 is provided on the bottom right side of the fixing member. The left boss 4-1 and the right boss 4-2 are arranged parallel to each other. The left boss 4-1 is used to limit the positioning of a first coaxial connector 1. The left boss 4-1 contacts the outer diameter axial surface of the first coaxial connector 1 and the end face of the connection port of the first coaxial connector 1. The right boss 4-2 is used to position a second coaxial connector 2. The right boss 4-2 contacts the outer diameter axial surface of the second coaxial connector 2 and the end face of the connection port of the second coaxial connector 2.

[0044] A method for operating a double-ended radial offset device includes the following steps:

[0045] The fixing member 4 is placed between the first coaxial connector 1 and the second coaxial connector 2, so that the left boss 4-1 and the right boss 4-2 of the fixing member 4 contact the first coaxial connector 1 and the second coaxial connector 2 respectively. The left boss 4-1 contacts the outer diameter axial surface of the first coaxial connector 1 and the end face of the connection port of the first coaxial connector 1, thus completing the axial and radial positioning of the first coaxial connector 1. The right boss 4-2 contacts the outer diameter axial surface of the second coaxial connector 2 and the end face of the connection port of the second coaxial connector 2, thus completing the axial and radial positioning of the second coaxial connector 2, so that the first coaxial connector 1 and the second coaxial connector 2 remain parallel, and the connector 2 is offset.

[0046] Example:

[0047] See Figure 5 , Figure 6 , Figure 7 and Figure 8 Given the dimensions of the first coaxial connector 1, the second coaxial connector 2, the connector 3, and the fixing member 4, as shown in the figure below, the radial displacement X of the connector 3 can be calculated when using the first coaxial connector 1, the second coaxial connector 2, and the fixing member 4:

[0048] X = 6.2 - 5.86 = 0.34 (mm)

[0051] Alternatively, the dimensions of the fastener 4 can be designed according to the required angle.
