Background
With the widespread and deep application of radio frequency and wireless technology, the frequency of use of coaxial connectors has also increased greatly and has grown rapidly. As is well known, coaxial connectors and coaxial cables are used for transmitting high-frequency radio frequency microwave signals, and reliable connection can effectively reduce reflection at the connection position of the cable and the connector and improve communication efficiency. For devices with coaxial connector input/output ports, reliable connection inspection of the coaxial cable to the connector before the rf microwave signal is turned on is critical. Because unreliable connections or unconnected connections can create significant reflections at the ports, attenuating the radio frequency signal. In severe cases, permanent damage to the equipment can result. The coaxial cable connector commonly used at present has no connection detection output terminal, and has no connection detection function. The important confirmations of whether the coaxial cable is reliably connected and whether the connection port is correct are currently judged by only relying on manual visual inspection, which is inefficient and easy to miss inadvertently.

Detailed Description
The invention is further described with reference to the accompanying drawings and specific examples:
as shown in fig. 1 to 4, the coaxial connector with the connection detection output terminal of the present invention includes a coaxial connector body 1 with a mounting flange, a spiral spring 2, and an annular spring cap 3.
The spiral spring sheet 2 has four sections, and each section is one quarter turn and is symmetrically distributed around the coaxial connector body 1 structurally. The spiral spring 2 is made of conductive metal, and the surface of the spiral spring is insulated to form an insulating layer.
The spring plate cap 3 is made of conductive metal, and the surface of the spring plate cap is subjected to conductive treatment to form a conductive layer. The purpose of the conductive treatment of the surface is to prevent the oxidation of the metal surface from affecting the electrical connection performance, to make up for the defect of poor conductive performance caused by the oxidation of the surface, and to ensure that the connection detection output terminal 4 stably and reliably outputs a low-level signal when the coaxial cable is connected.
The mounting flange plate is provided with four through holes which are structurally symmetrical among the original mounting holes. The spring piece cover cap 3 is sleeved on the coaxial connector body 1 in a suspending way. The spiral spring sheet 2 passes through the through hole and leaks out a certain length at the bottom of the installation flange plate, and the length and the size can be designed according to actual requirements without special requirements. One end of the spiral spring plate 2 is fixedly connected with the lower surface of the spring plate cap 3, and the other end is subjected to conductive tin spraying treatment to form a tin layer which is used as a connection detection output terminal 4. The purpose of the conductive tin plating process is to facilitate the bonding of the wire by the designer in actual engineering applications. The spiral spring sheet 2 and the mounting flange plate are fixedly connected by adopting insulating rubber at the through hole so as to ensure electrical insulation between the spiral spring sheet 2 and the mounting flange plate.
It should be noted that the number of the spiral spring 2 may be two, one-half of the number of turns, or three, one-third of the number of turns. By the arrangement, the smooth connection of the coaxial cable can be ensured to be even in stress without affecting the smooth connection of the coaxial cable, the coaxial cable is symmetrical and attractive in structure, and the electrical characteristics of the connection detection output terminal 4 are ensured to be consistent with the equipment shell after the coaxial cable is connected.
The following detailed description of the working process and principle of the present invention further shows the advantages of the present invention:
due to the insulation treatment, when the cable is not connected, the four-spiral spring plate 2 is suspended, and enough gaps are reserved between the spring plate and the coaxial connector body 1 and between the spring plate cap 3 and the coaxial connector body 1 to ensure electrical isolation. When the cable is connected with the coaxial connector, the spring plate is compressed, and then the spiral spring plate 2 is electrically connected with the coaxial connector through the spring plate cap 3, and meanwhile, the coaxial connector is electrically connected with the equipment shell, and the exposed output terminal of the spiral spring plate 2 outputs a low-level signal. The system designer can determine whether the cable is connected by using the low level signal.
In the whole, the coaxial connector with the connection detection output terminal provided by the invention adopts a purely mechanical structure, has long service life, has no influence on the shielding function of the connector, is stable and reliable, is not easily influenced by the surrounding environment to fail, has strong practicability and application value, and is worthy of popularization in the industry.
