Detailed Description
The embodiments of the present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, fig. 2 and fig. 3, in the connector, the microwave input and output structure, the cavity filter and the microwave device embodiment of the present invention, the connector is used for transmitting microwave signals, and particularly for signal transmission inside and outside a shielded space, for example, the introduction and the extraction of microwave signals are realized in the cavity filter. In the present embodiment, the connector includes an inner conductor 1, an insulating dielectric sleeve 2, and an elastic contact member 3; the insulating medium sleeve 2 is sleeved outside the inner conductor 1 and located at a set position in the length direction of the inner conductor 1, and is used for fixing the position between the inner conductor 1 and a shielding material (such as a shielding cover of a cavity filter) when the microwave signal is transmitted between the inside and the outside of a device of which the inner conductor 1 is shielded, and determining the distance between the shielding material and the inner conductor 1 to ensure that the shielding material is equivalent to an outer conductor of a coaxial transmission line, so that the connector obtains a set transmission impedance when transmitting the microwave signal, and the connector is actually equivalent to a coaxial line and is suitable for the transmission of the microwave signal; in this embodiment, by setting the depth of the mounting position on the shielding material through which the connector is required to pass and the distance between the shielding material and the inner conductor of the connector (which is determined by the thickness of the insulating dielectric sleeve), the transmission impedance can be controlled to a desired value, for example, the transmission impedance can be made 50 ohms. In this embodiment, the insulating medium sleeve 2 is made of teflon, the insulating medium sleeve 2 has a cylindrical body with an upper edge 21 and an extension column 22, the outer dimension of the upper edge 21 is greater than the outer dimension of the extension column 22, or the outer diameter of the upper edge 21 is greater than the outer diameter of the extension column 22, so that a platform structure is formed at the joint of the upper edge 21 and the extension column, or an outer shape similar to a bolt with a nut with a large head and a small bottom is formed, please refer to fig. 2; in addition, the insulating medium sleeve 2 is also provided with an inner conductor mounting through hole which penetrates through the upper edge 21 and the extension column 22 and is used for mounting the inner conductor 1; although the inner conductor mounting through hole is not marked in the drawings, it can be clearly seen in fig. 1 to 3 that the inner conductor 1 penetrates the insulating dielectric sleeve 2 in the length direction (the direction from top to bottom in fig. 1 to 3).
In the present embodiment, the elastic contact member 3 is elastically connected to the inner conductor 1 and extends outward from one end of the inner conductor 1; the spring contact assembly 3 comprises a contact head 31 located outside the inner conductor 1, the contact head 31 being intended for connection with a contact 81 of an external circuit board 8 or device (see fig. 6); the end of the contact head 31 connected with the contact 81 is provided with a contact end 33 made of flexible conductive material, and the contact end 33 deforms when the contact 81 makes contact, so that the contact area becomes larger, and stable connection is formed. Such a connection makes the connection stable without damaging the contacts 81 on the circuit board or the device, and makes the contact resistance small due to the large contact area, thereby facilitating the maintenance of the transmission impedance of the connector.
In this embodiment, the contact end is made of a high ratio metal and colloid mixed flexible material or a flexible metal. For example, it may be formed by gold plating of conductive silver paste, or formed by conductive hydrogel, or the like. And the top of the contact head 31 is provided with a mounting groove with a set shape, the inner wall of the mounting groove is provided with a specific shape, and the mounting groove is matched with the shape of the contact end 33 to form a locking or fastening structure. For example, as shown in fig. 1 and fig. 2, the inner surface of the middle section of the mounting groove has a protruding structure protruding toward the central axis of the mounting groove, a recess is provided at a position corresponding to the contact end to mate with the protruding structure, and the protruding structure and the recess mate to form a locking structure to fix the relative position between the contact head and the contact end. It can be seen from fig. 1 and 2 that the top and bottom of the contact end have a larger profile, while the middle part has a smaller profile or outer diameter due to the need to fit with the protruding structure in the mounting recess. Figures 8 and 9 show more clearly the two alternative locking arrangements of the present embodiment. Alternatively, the shape of the mounting recess and the shape of the contact end 33 are not limited to the type shown in the embodiment.
In summary, the contact end 33 has an outer shape that is adapted to the shape of the mounting recess, and since the contact end 33 is made of a flexible material and has a certain deformability, it can be placed in the mounting recess with a tight fit by pressing. In addition, in order to ensure the transmission effect and protect the contacts of the circuit board or device, the contact end 33 has a raised portion (see fig. 1 and 2) higher than the contact head 31, and the raised portion contacts with the contact 81 before the contact head 31, so as to ensure the deformation of the contact end 33 under stress, thereby ensuring a larger contact area and a more stable connection.
In the present embodiment, as shown in fig. 2 and 3, the inner conductor 1 includes a head portion 12 and a tail portion 13 having a columnar shape, the top end of the head portion 12 has an edge portion 11 protruding outward, the head portion 12 has a head through hole penetrating through the central axial direction thereof; the tail 13 has a connecting portion 131 adapted to the head through hole, and the connecting portion 131 connects the tail 13 to the bottom end of the head 12 through a tight fit with the head through hole. The cross section of the edge part 11 is larger than that of the middle part of the head part 12, the middle section of the tail part 13 also has a platform structure with larger outer diameter, and the outer diameter of the platform structure is larger than the part of the tail part 13 extending out of the insulating medium sleeve 2; thus, the respective platform structures are formed at the middle sections of the edge portion 11 and the tail portion 13. The purpose of this setting is under the prerequisite of guaranteeing signal transmission for inner conductor 1 can pass insulating medium cover 2, and is fixed down in the position of setting for, guarantees the relative position relation in the length direction (from top to bottom in fig. 1 and fig. 2) between the two, guarantees that relative position shift can not appear.
Specifically, the structure of the inner conductor 1 and the structure of the insulating dielectric sleeve 2 are matched, so that the inner conductor 1 which is installed in place is stressed in the direction from top to bottom in fig. 1 and 2 and cannot generate relative movement in the insulating dielectric sleeve 2. The inner conductor mounting through-hole in the insulating dielectric sleeve 2 also has a varying diameter in cooperation with the outer shape of the inner conductor 1 so that the tail portion 13 of the inner conductor 1 can protrude out of the inner conductor mounting through-hole while the head portion 12 is prevented from staying in the inner conductor mounting through-hole. At the same time, the structure and connection of the head 12 and the tail 13 as described above also provides the elastic assembly with a mounting cavity 14, specifically the mounting cavity 14 is actually part of the head through hole.
In this embodiment, the inner conductor 1 and the insulating dielectric sheath 2 are installed in the direction from top to bottom in fig. 1 and 2, and the inner conductor 1 is placed in the insulating dielectric sheath 2 and pushed downward into position. As mentioned above, after pushing in place, the above-mentioned structure on the shape of the inner conductor 1 and the inner conductor installation through hole with varying diameter in the insulating medium 2 make the inner conductor 1 not move in the insulating medium sleeve 2 when being forced from top to bottom; however, when the inner conductor 1 is forced from bottom to top, displacement may occur, and for this reason, in this embodiment, the positioning fin 15 is disposed on the outer wall of the middle section of the head 12 of the inner conductor 1, and a fin positioning recess (see fig. 3) is disposed on the side wall of the insulating medium sleeve 2 corresponding to the inner conductor mounting through hole, so that when the inner conductor 1 enters the insulating medium sleeve 2 from top to bottom, the positioning fin 15 enters the fin positioning recess; when the inner conductor 1 is forced from bottom to top, the positioning fins 15 and the fin positioning recesses are matched, so that the inner conductor 1 cannot move along the forced direction, namely, the inner conductor 1 cannot be separated from the upper edge 21 of the insulating medium sleeve 2. Thus, the relative position between the inner conductor 1 and the insulating medium sleeve 2 is fixed, and the relative movement is avoided.
Further, in the present embodiment, as shown in fig. 3, the portion of the head through hole not occupied by the connection portion 131 and the top surface of the connection portion 131 form a mounting cavity 14 in which the elastic member is mounted; the elastic contact assembly 3 further includes a spring 32, the spring 32 being disposed in the elastic assembly mounting cavity 14 between the bottom of the elastic assembly mounting cavity 14 and the contact head 31, the contact head 31 being mounted in the elastic assembly mounting cavity 14. In addition, the connecting portion 131 is further provided with a fixing protrusion 132, after the connecting portion 131 enters the head through hole in a tight fit manner and moves to a proper position, a certain pressure is provided at the periphery of the corresponding portion of the inner conductor 1, so that the side wall of the corresponding position of the head 12 deforms corresponding to the fixing protrusion 132 in a compression joint manner (or a corresponding recess is formed in the inner wall of the corresponding position of the head through hole and is tightly attached to the fixing protrusion 132 through a compression joint action), thereby realizing stable connection between the head 12 and the tail 13 of the inner conductor 1, and preventing the tail 13 from moving in the head through hole within an allowable stress range. In this embodiment, the fixing protrusion 132 includes a continuous annular protrusion or an intermittent annular protrusion. The spring 32 is compressed when the elastic contact assembly 3 contacts the contact 81, and provides a proper contact pressure, thereby ensuring the reliability and stability of the contact.

In this embodiment, a case where a microwave input/output structure is disposed or constructed on a cavity filter is described as an example. As shown in fig. 4, 5 and 6, fig. 4 shows a microwave input-output structure with a connector mounted, fig. 5 shows a microwave input-output structure without a connector mounted, and fig. 6 shows a microwave input-output structure with a connector and a circuit board mated.
As shown in fig. 5, the connector mounting through hole 51 is recessed downward from the outer surface of the shield cover 5 and has a varying aperture such that a stepped plane 52 is formed on the connector mounting through hole 51; this structure allows the extending post 22 of the insulating dielectric housing 2 of the connector to enter the shielded space 41, while the upper edge 21 stays in the connector mounting through hole 51 due to the contact with the above-mentioned step plane 52, thereby fixing the connector to the shield cover 5. It is worth mentioning that the position of the step plane 52 and the lower edge of the upper edge 21 determine the depth of the inner conductor 1 extending into the shielded space 41, which is not only related to the coupling degree of the signal, but also affects the length of the shielding cover as the outer conductor due to the depth of the recess, i.e. also affects or adjusts the transmission impedance of the whole microwave input and output structure.
As shown in fig. 5, the microwave input/output structure further includes a signal coupling unit 7 disposed in the shielded space 41, the signal coupling unit 7 includes a coupling loop surrounding an inner conductor portion of the connector extending into the shielded space 41 and a connecting piece connected to the coupling loop, and one end of the connecting piece is further connected to a signal output or input point 43 defined in the shielded space 41.
In order to ensure the position of the connector part extending into the shielded space 41, the microwave input/output structure further comprises a fixing medium sleeve 6 for fixing the inner conductor part extending into the shielded space; the inner conductor portion extending into the shielded space enters the fixed dielectric sleeve 6 to ensure its spatial positional relationship in the above-mentioned shielded space 41. In this embodiment, the fixing dielectric housing 6 is a hollow cylindrical member formed of teflon in which a tail placement through hole 61 for placing the tail 13 of the inner conductor 1 is provided, the tail 13 entering the closed space 41 is placed in the tail placement through hole 61 to play a role of adjusting or positioning the attitude or position of the connector, the fixing dielectric housing 6 is disposed between the coupling ring and the inner conductor portion protruding into the shielded space 41, and its position in the shielded space is fixed by a mounting ring 42 provided on the bottom inner wall of the shield shell 4 of the shielded space.
In this embodiment, in a specific implementation, the signal coupling component 7 and the fixed dielectric sleeve 6 are first disposed at proper positions in the shielded space of the cavity filter, and since the coupling ring and the connecting piece in the signal coupling component 7 in this embodiment are composed of a metal strip with a ring structure at one end, the fixed dielectric sleeve 6 is placed in the mounting ring 42 and the metal strip is disposed, then the metal cover plate of the cavity filter, i.e. the shielding cover 5, is mounted, and then the connector and other cavity filter components are placed. When the cavity filter is assembled, the circuit board assembly or circuit board 8 is mounted to form the system connection structure and device.
When the circuit board 8 is assembled, its contacts 81 are in contact with the outer metal and the flexible metal of the spring contact assembly 3. The contact 81 and contact end 33 are sized to match each other for impedance matching, typically requiring 50 ohms of impedance.
