detailed description:

The present invention will be further described in detail below in conjunction with accompanying drawings 1 to 3 and embodiments.

A universal conversion device for cable pin-type plugs, as shown in Figure 1, including a conductive rubber contact plate 3, a metal contact plate 4, a non-metallic movable pressure plate 6, a compression bolt 7, a conversion device body 5 and an outlet Cable 8, conductive rubber contact plate 3, metal contact plate 4 and non-metallic movable pressure plate 6 are installed in conversion device body 5.

The shape, size and spacing of the contact end 9 on the adjacent surface of the conductive rubber contact plate 3 and the 1-pin plug of the cable under test meet the requirements of the cable under test when the universal adapter device of the cable pin-type plug is docked with the 1-pin plug of the cable under test. Each pin 10 of the 1-pin plug is in reliable contact with at least one contact and each contact will not be in contact with two pins 10 of the 1-pin plug of the cable under test at the same time, as shown in Figure 2 and Figure 3 . In Fig. 3, the three circles on the contact end intersect with some contact ends, representing the situation that the three pins 10 of the 1-pin plug of the tested cable are in contact with the contact end. The shape of the contact end 9 on the adjacent surface of the conductive rubber contact plate 3 and the needle plug of the tested cable 1 can be hemispherical, cuboid, cube, truncated cone or cylinder. The smaller the cross-sectional size of the contact terminal 9 and the pin of the tested cable 1-pin plug and the distance between adjacent contact terminals 9, the smaller the cable pin-plug universal adapter device is docked with the tested cable 1-pin plug The more reliable the contact, the better the versatility. It is preferable that the distance between the adjacent contact ends 9 is not greater than the diameter of the pin of the needle plug and the distance between the adjacent pins. The cross-sectional size of the pin contact is not greater than the cross-sectional size of the pin. The contact ends 9 are evenly distributed on the conductive rubber contact disk 3 with the same spacing. The contact ends 9 are hemispherical and the diameter of the hemisphere is 0.5 mm. The outer diameter of the conductive rubber contact disc 3 is 50 mm, 100 mm, 150 mm and other size series, which are selected according to the pin diameter of the 1-pin plug of the tested cable.

The metal contact disc 4 corresponds to the contact end of the adjacent surface of the conductive rubber contact disc 3, and the contact ends of the metal contact disc 4 and the adjacent surface of the conductive rubber contact disc 3 can be made by pressing or bonding. The contact ends are in one-to-one contact, and other methods such as bolt connection and riveting may also be used, as long as the two contact ends can be reliably contacted.
