[0022] To make the technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] like Figure 1 As shown, a connector overlap installation structure includes an inner cavity connector 1 and an external connector 2. The inner cavity connector 1 is used to be fixed inside the filter cavity, and the external connector 2 is used to be fixed outside the filter. The external connector 2 is connected to the inner cavity connector 1 by plugging one end thereof, thereby realizing a stable connection structure and achieving the purpose of stable indicators.

[0024] like Figure 1 、 Figure 2 As shown, an inner cavity core 15 is provided in the inner cavity connector 1, and a deep hole sleeve 24 for sleeved on the outside of the inner cavity core 15 and abutted and clamped is provided in the external connector 2. The deep hole sleeve 24 is matched with the inner cavity core 15 and plugged in to improve the connection stability. It should be noted that the inner cavity connector includes an inner cavity body 11 and an inner connecting plate 12 for connecting and fixing with the filter cavity body. A plug-in cavity 13 is provided in the inner cavity body 11, and the inner cavity core 15 is coaxial with the axis of the plug-in cavity 13. At the same time, the external connector 2 includes a plug-in inner end 21 and an outer connecting plate 23 for connecting and fixing with the outside of the filter. A plug-in inner cavity 211 is provided in the plug-in inner end 21, and the deep hole sleeve 24 is coaxial with the axis of the plug-in inner cavity 211.

[0025] like Figure 2 、 Figure 3As shown, inner cavity petals 14 are provided in the plug cavity 13. In order to improve the connection stability between the plug inner end portion 21 and the inner cavity connector 1, the plug inner end portion 21 is inserted between the inner cavity petals 14 and the inner side wall of the plug cavity 13 and abuts against each other, thereby forming a certain clamping force, thereby further improving the connection stability between the inner cavity connector 1 and the external connector 2 and achieving the purpose of stable indicators.

[0026] like Figure 2 、 Figure 3 As shown, a spring metal ring 26 is disposed on the outer side of the plug-in inner end portion 21. The spring metal ring 26 abuts against the inner sidewall of the plug-in cavity 13. Furthermore, a protruding ring 212 is disposed on the inner side of the plug-in inner end portion 21, abutting against the outer side of the inner cavity petals 14. Therefore, the plug-in inner end portion 21 cooperates with the inner cavity petals 14 via the protruding ring 212 to enhance the connection stability between the inner cavity connector 1 and the external connector 2, thereby significantly improving the stability of the indicators.

[0027] like Figure 2 、 Figure 3 As shown, an internal plastic part 4 is inserted into the inner side of the inner cavity petals 14. A matching slot 41 is provided on the outer side of the internal plastic part 4. Correspondingly, an external plastic part 3 is inserted into the plug-in inner groove. The corresponding end of the external plastic part 3 is reduced in diameter and matched with the matching slot 41. When the internal plastic part 4 abuts against the inner cavity connector 1, the external plastic part 3 abuts against the external connector 2, thereby reducing the difficulty of docking the corresponding inner cavity core 15 and the deep hole sleeve 24 when the external plastic part 3 and the internal plastic part 4 are matched and connected to each other, thereby reducing the difficulty of replacing filters of different frequencies, and significantly improving practicality.

[0028] At the same time, multiple equally spaced fins 241 are installed at the end of the deep-hole sleeve 24, and a filter-matched gap 5 is formed between the inner connecting plate 12 and the outer connecting plate 23. These fins 241 clamp the inner core 15, improving the connection stability and performance between the inner connector 1 and the outer connector 2.

[0029] It's worth noting that a connecting outer end 22 is provided at the end of the external connector 2, away from the inner plug end 21. Within this outer end groove 221 is a connecting outer end rim 222, and within this groove 221, outer end outer petals 222 and inner end outer petals 223 are arranged sequentially from the outside to the inside. To further enhance the sealing properties of the connection, sealing rings 25 are provided on the end of the external connecting plate 23 facing the inner cavity connector 1 and on the outer periphery of the connecting outer end 22, thereby extending the service life of the connector's lap joint mounting structure and effectively reducing its operating costs.

[0030] In summary, the present application provides a connector overlapping installation structure, which is connected through the inner cavity connector 1 and the external connector 2, so that the combination of the embedded foreman connector and the external connector 2 can effectively reduce the cavity space occupation and effectively solve the problem of insufficient filter cavity space; at the same time, the combination of the inner cavity petals 14, the wing bars 241 and the convex ring 212 is adopted to realize the formation of a clamping force when the inner cavity core 15 is inserted into the deep hole sleeve 24, and significantly improve the stability of the connection structure between the inner cavity connector 1 and the external connector 2 and the connection stability between the deep hole sleeve 24 and the inner cavity core 15, thereby achieving the purpose of index stability.
