Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict. In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," and "connected" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The first embodiment is as follows:

as shown in fig. 1: a radio frequency switch connector comprising an inner conductor set, an insulator set, a spring 4 and a housing 3, the inner conductor set comprising a first inner conductor 11, a second inner conductor 12 and a contact inner conductor 13, the insulator set comprising a first insulator 21, a second insulator 22 and a third insulator 23, the contact inner conductor 13 and the third insulator 23 being connected by the spring 4.

First inner conductor 11 is the cylinder, and the left side is for inserting the B end, and the right side is for inserting the A end, it wears out to insert the A end shell 3, spring 4 elasticity makes contact inner conductor 13 leans on in first inner conductor 11, second inner conductor 12 sets up first inner conductor 11 bottom, second inner conductor 12 wears out 3 one end of shell for inserting the C end, contact inner conductor 13 sets up in second inner conductor 12 upper right side.

The first insulator 21 is arranged on the left side of the second inner conductor 12, the first insulator 21 is movably sleeved on the first inner conductor 11, and can move back and forth on the first inner conductor 11 through external force; the second insulator is fixedly arranged between the shell and the second inner conductor; the third insulator is fixedly arranged between the shell and the contact inner conductor, the first insulator 21 is made of PTFE materials and is light in weight and easy to slide, and the second insulator 22 and the third insulator 23 are made of PPS materials with high hardness, so that the holding force of parts is guaranteed.

The spring 4 is in a compressed state and reacts against the contact inner conductor 13 and the first insulator 21 in a free state, the elastic force of the spring 4 reacts against the contact inner conductor 13 and the first insulator 21, so that the contact inner conductor 13 and the first insulator 21 move leftwards, and as the second inner conductor 12 is positioned at the bottom of the first inner conductor 11, the lower half part of the contact inner conductor 13 is in contact with the second inner conductor 12 in the moving process, so that the contact inner conductor 13 does not move any more, and at the moment, a gap still exists between the left end of the first insulator 21 and the shell 3, but the elastic force of the spring 4 is larger, so that the contact inner conductor 13 tilts and is in contact with the first inner conductor 11; if the connector is accessed at access B, the first insulator 21 is pushed to be flush with the left end of the first inner conductor 11 by moving to the right under the external force and the nature of the access itself, and the contact inner conductor 13 is moved to the right by being driven during the pushing of the first insulator 21, so that the contact inner conductor 13 is separated from the second inner conductor 12.

To sum up:

in a free state: the contact inner conductor 13 is inclined and in good contact with the first inner conductor 11, while the contact inner conductor 13 is in good contact with the second inner conductor 12, forming an electrical transmission circuit.

Namely, the access A end is conducted with the access C end to form a first loop;

when in a matching state: under the condition of external force and the property of the access device, the contact inner conductor 13 is well disconnected from the second inner conductor 12, and signals are transmitted at two ends of the first inner conductor 11 to form an electric transmission loop.

Namely, the access terminal A is conducted with the access terminal B to form a loop II.
