SU579668A1 - Connecting unit for central conductors of coaxial line - Google Patents

Description

i

Exploration refers to the technique of ultra-high frequencies (UHF), can be used for non-AI. high-frequency paths and microwave ovens.,

A well-known joint is the central conductor of a coaxial line containing a contact element .l

However, the known connecting assembly has a complex structure that makes it difficult to manufacture them due to the small size of the conductors.

The purpose of the invention is to simplify the design.

In the proposed connecting node of the central conductors of the coaxial line containing the contact element, a collet is located at the end of the central conductor of the coaxial line, inside which the contact element in the form of two truncated cones with a common small base is mounted.

FIG. Figure 1 shows a structural diagram of the connecting node; Figure 2 shows the connecting nodes at the moment of contact.

At the end of the center (shni1 o P) of the ravodnik 1 there is a rape-enclosing center 2, inside which the contact 1 Element 3 is mounted with the possibility of moving, in the form of two truncated cones with a common axis. The external conductor 4 for connection with a similar connector has a nut 5 and a sleeve c. The center conductor 1 grooves numb and crimped so & time that its diameter is less than the diameter of the contact element 3. The plane 7 of the contact element 3 turns out beyond the plane 8 of the outer conductor 4 for reliable KOit contact with a similar connector. It is achieved that TeMj that the collet 2 of the center conductor 1 in a free state is compressed and pushes the contact element 3, and its internal diameter holds the contact in the conductor. When two similar connectors are connected, the external conductors 4 firmly rest against one another and contact along the plane 8, and the central 1 conductors contact along the planes 7.

At the moment of contacting the two connecting nodes (see FIG. 2), the contact pressure between them is created by squeezing 11 Danga 2 central conductors 1. Contact ibie elements 3, resting one against the other with their V1H ends, transfer pressure to the central first conductors 1, The conical planes 9 of the contact elements 3 press on the carotid planes 1O of the central conductors and move inside them. The collets of the 2 neutral conductors tend to compress the pressure of their own planes on the conical strip 9 contact elements 3 The electrical contact between the planes of these planes and the ends of the contact elements 3. The described connecting node of the central conductors is aptically matched in the working frequency range of the coaxial line, the presence of grooves in the central conductors has practically no effect on the matching. The connection node of the central conductors of the coaxial line, which contains a horse element, characterized in that, in order to simplify the design, at the end of the central conductor of the coaxial line there is a collet, inside which the contact element in the form of two truncated cones with a common small basis.
