Technical Field

[0001] This application relates to the field of filter technology, and in particular to a connector and a filter. Background Technology

[0002] Filters, as frequency selection devices, are widely used in the field of communications, especially in radio frequency communications. In base stations, filters are used to select communication signals and filter out noise or interference signals outside the communication signal frequency, while connectors are an important component connecting filters and external communication devices.

[0003] In the field of 5G communication technology, due to the reduction in the overall size of radio frequency devices, the shell of the connector, which was originally used for grounding, has been integrated with the filter cavity. In order to adapt to the reduction in size, the existing connector is prone to skewing during compression, resulting in defects such as broken pins, which affects the radio frequency performance of the filter. Summary of the Invention

[0004] This application mainly provides a connector and a filter to solve the problem of connectors being prone to skewing during compression.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is to provide a connector. The connector includes: an insulating base; a central guide rod fixedly disposed in the insulating base; a movable conductor having a first guide channel, the central guide rod passing through the first guide channel and slidably disposed with the first guide channel; and an elastic body sleeved on the central guide rod and elastically disposed between the insulating base and the movable conductor; wherein the movable conductor is electrically connected to the central guide rod and / or the elastic body.

[0006] In some embodiments, the connector further includes an outer conductor having a second guide channel. The outer conductor is fixedly disposed on the insulating base and coaxially disposed with the central guide rod. The movable conductor is disposed in the second guide channel and circumferentially limited by the second guide channel, and the movable conductor slides in conjunction with the second guide channel.

[0007] In some embodiments, the outer periphery of the movable conductor is provided with a travel groove, and the inner periphery of the outer conductor is provided with a limiting portion, which is placed in the travel groove.

[0008] In some embodiments, the connector further includes an outer conductor, which is fixedly disposed on the insulating base and coaxially disposed with the central guide rod;

[0009] The movable conductor includes an integral cylindrical body and a base. The base is provided with the first guide channel. The central guide rod slides through the cylindrical body and the first guide channel. The cylindrical body is sleeved on the outer periphery of the outer conductor and slides with the outer conductor.

[0010] In some embodiments, the outer periphery of the outer conductor is provided with a first stop portion, and the inner periphery of the cylinder is provided with a second stop portion, the first stop portion and the second stop portion being mutually anti-detached and limited.

[0011] In some embodiments, the outer conductor and the active conductor are electrically connected.

[0012] In some embodiments, the connector further includes a conductive post disposed on the side of the insulating base opposite to the movable conductor, and the conductive post is also electrically connected to the outer conductor, the central guide rod, and / or the elastomer.

[0013] In some embodiments, the central guide rod includes a first guide post and a second guide post arranged coaxially, wherein the cross-sectional area of ​​the second guide post along the axial direction is greater than the cross-sectional area of ​​the first guide post along the axial direction.

[0014] The first guide channel includes a first sliding cavity and a second sliding cavity arranged coaxially, the first guide post is slidably engaged with the first sliding cavity, and the second guide post is slidably engaged with the second sliding cavity.

[0015] In some embodiments, the central guide rod further includes a third guide post, which is coaxially arranged with the first guide post and the second guide post and located on the side of the second guide post away from the first guide post. The cross-sectional area of ​​the third guide post along the axial direction is smaller than the cross-sectional area of ​​the second guide post along the axial direction.

[0016] The first guide channel further includes a third sliding cavity, and the third guide post extends into the third sliding cavity and slides in cooperation with the third sliding cavity.

[0017] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide a filter. The filter includes the connector as described above.

[0018] The beneficial effects of this application are as follows: Unlike existing technologies, this application discloses a connector and a filter. By providing a first guide channel for the movable conductor, defining a central guide rod that passes through and slides within the first guide channel, and an elastic body fitted onto the central guide rod and elastically positioned between the insulating base and the movable conductor, when the movable conductor is compressed, it can only move back and forth along the axial direction of the central guide rod. The central guide rod provides reliable axial protection for the movable conductor, and the elastic body provides uniform axial support to the movable conductor, further reducing the risk of the movable conductor skewing under stress. This ensures that the movable conductor is not easily skewed when moving along the axial direction of the central guide rod, and effectively guarantees the contact between the movable conductor and external communication devices. Therefore, the connector provided by this application effectively improves the situation where the movable conductor is easily skewed when compressed, thus preventing connector damage, improving connector quality, and effectively ensuring the electrical connection performance of the connector.

[0027] This application provides a connector 100, see reference. Figure 1 , Figure 1 This is a schematic diagram of a connector embodiment provided in this application.

[0028] The connector 100 generally includes an insulating base 10, a central guide rod 20, a movable conductor 30, an elastic body 40, and a conductive post 50. The central guide rod 20 is fixedly disposed on the insulating base 10, the movable conductor 30 is slidably disposed on the central guide rod 20, the elastic body 40 is sleeved on the central guide rod 20 and elastically disposed between the insulating base 10 and the movable conductor 30, and the conductive post 50 is disposed on the side of the insulating base 10 away from the movable conductor 30. The movable conductor 30 is electrically connected to the central guide rod 20 and / or the elastic body 40, and the conductive post 50 is electrically connected to the movable conductor 30 through the central guide rod 20 and / or the elastic body 40.

[0029] The connector 100 can be installed on the filter body, and the conductive post 50 is also electrically connected to the components inside the filter body, so that the connector 100 can perform functions such as conduction and communication. The conductive post 50 can be inserted into the filter body, or the conductive post 50 can be soldered to the filter body, or the conductive post 50 can be screwed to the filter body. This application does not limit this.

[0030] The insulating base 10 is made of insulating material. In addition to mounting and fixing the center guide rod 20, the elastic body 40 and the conductive post 50, the insulating base 10 also has the function of isolation and insulation. It isolates the conductive center guide rod 20 and / or the elastic body 40 from contact with easily conductive parts such as the metal shell of the filter body, thereby ensuring good communication performance of the connector 100 and improving the radio frequency performance of the connector 100.

[0031] The elastic body 40 can be a compression spring, a pneumatic spring, or an elastic sleeve, etc., and this application does not limit it, as long as it can be elastically compressed between the insulating base 10 and the movable conductor 30. At least one of the elastic body 40 and the central guide rod 20 is electrically connected to the movable conductor 30.

[0032] Specifically, the movable conductor 30 is provided with a first guide channel 31, and the central guide rod 20 passes through the first guide channel 31 and is slidably disposed with the first guide channel 31. Therefore, the central guide rod 20 and the movable conductor 30 are circumferentially limited by each other through the first guide channel 31, and the elastic body 40 can provide the movable conductor 30 with a uniform supporting force. When the movable conductor 30 is compressed, the movable conductor 30 can only move back and forth along the axial direction of the central guide rod 20. The central guide rod 20 can provide reliable axial protection for the movable conductor 30, and the uniform axial supporting force provided by the elastic body 40 to the movable conductor 30 can further reduce the risk of the movable conductor 30 being skewed by force, ensuring that the movable conductor 30 is not easily skewed when moving along the axial direction of the central guide rod 20, and can effectively ensure the contact between the movable conductor 30 and external communication devices.

[0033] See Figure 1 In one embodiment, the central guide rod 20 includes a first guide post 22 and a second guide post 24 coaxially arranged. The cross-sectional area of ​​the second guide post 24 along the axial direction is larger than the cross-sectional area of ​​the first guide post 22 along the axial direction. The first guide post 22 is fixedly connected to the insulating seat 10. The elastic body 40 is sleeved on the first guide post 22 and elastically arranged between the insulating seat 10 and the movable conductor 30.

[0034] The first guide channel 31 includes a first sliding cavity 312 and a second sliding cavity 314 arranged coaxially. The first guide post 22 is slidably engaged with the first sliding cavity 312, and the second guide post 24 is slidably engaged with the second sliding cavity 314. The axial length of the second sliding cavity 314 also limits the travel of the movable conductor 30. In other words, the travel of the second guide post 24 along the second sliding cavity 314 is the travel of the movable conductor 30.

[0035] It can be seen that the first guide post 22 slides along the first sliding cavity 312, and the first guide post 22 is circumferentially limited by the first sliding cavity 312, that is, the first guide post 22 and the first sliding cavity 312 cannot deviate from each other axially and become skewed. The second guide post 24 slides along the second sliding cavity 314, and the second guide post 24 is circumferentially limited by the second sliding cavity 314, that is, the central guide rod 20 and the movable conductor 30 are doubly circumferentially limited by each other. Therefore, the central guide rod 20 can provide reliable axial protection for the movable conductor 30, improve the situation where the movable conductor 30 is easily skewed when compressed, thereby breaking the movable conductor 30 or causing the movable conductor 30 to fall off, improve the quality of the connector 100, and can also effectively ensure the electrical performance of the connector 100.

[0036] Further reading Figure 2 The central guide rod 20 also includes a third guide post 26, which is coaxially arranged with the first guide post 22 and the second guide post 24 and located on the side of the second guide post 24 away from the first guide post 22. The axial cross-sectional area of ​​the third guide post 26 is smaller than that of the second guide post 24. The first guide channel 31 also includes a third sliding cavity 316, into which the third guide post 26 extends and slides in cooperation with the third sliding cavity 316.

[0037] It should be noted that during the reciprocating sliding of the second guide post 24 along the second sliding cavity 314, the third guide post 26 always extends into the third sliding cavity 316, and the third guide post 26 reciprocates along the third sliding cavity 316. Therefore, the third guide post 26 is circumferentially limited by the third sliding cavity 316, and the central guide rod 20 can provide the movable conductor 30 with an additional layer of axial protection, further improving the situation where the movable conductor 30 is prone to skewing when compressed.

[0038] See Figure 3 In another embodiment, the connector 100 further includes an outer conductor 60, which has a second guide channel 62. The outer conductor 60 is fixedly disposed on the insulating base 10 and coaxially disposed with the central guide rod 20. The movable conductor 30 is disposed in the second guide channel 62 and is circumferentially limited by the second guide channel 62, and the movable conductor 30 slides in cooperation with the second guide channel 62.

[0039] Furthermore, the movable conductor 30 is circumferentially limited by both the inner central guide rod 20 and the outer conductor 60. In other words, the movable conductor 30 can be well protected axially by being circumferentially limited on both the inner and outer sides, which can effectively prevent the movable conductor 30 from easily tilting when compressed.

[0040] In this embodiment, the first guide channel 31 is a guide hole, and the central guide rod 20 is a shaft-like structure, with the central guide rod 20 slidingly engaged with the first guide channel 31. Alternatively, the sliding engagement between the central guide rod 20 and the movable conductor 30 can also be achieved using the method described in the previous embodiment, which will not be repeated here.

[0041] The outer periphery of the movable conductor 30 is provided with a travel groove 33, and the inner periphery of the outer conductor 60 is provided with a limiting part 64, which is placed in the travel groove 33. Therefore, the outer conductor 60 is axially prevented from disengaging by the limiting part 64 and the travel groove 33, and the axial travel of the movable conductor 30 can be limited.

[0042] The outer conductor 60 and the movable conductor 30 are electrically connected. For example, the limiting part 64 is also provided with a conductive feed point, which is electrically connected to the movable conductor 30. This application does not limit the electrical connection method between the outer conductor 60 and the movable conductor 30. The conductive post 50 is electrically connected to the outer conductor 60, so the movable conductor 30 is electrically connected to the conductive post 50 in at least two ways, which can significantly improve the electrical performance of the connector 100 and reduce the occurrence of open circuits in the connector 100.

[0043] See Figure 4 In another embodiment, the connector 100 includes an outer conductor 60, which is fixedly disposed on the insulating base 10 and coaxially disposed with the central guide rod 20. In this embodiment, the outer conductor 60 is a hollow shaft, which is sleeved on the outside of the central guide rod 20, and an elastic body 40 is disposed between the outer conductor 60 and the central guide rod 20. The outer conductor 60 can also be a solid shaft, coaxially disposed with the central guide rod 20, and the central guide rod 20 is connected to the outer conductor 60, with the elastic body 40 elastically disposed between the outer conductor 60 and the movable conductor 30.

[0044] Specifically, the movable conductor 30 includes an integral cylindrical body 32 and a base 34. The base 34 is provided with a first guide channel 31. The central guide rod 20 is slidably engaged with the first guide channel 31 via the cylindrical body 32. The cylindrical body 32 is sleeved on the outer periphery of the outer conductor 60 and is slidably engaged with the outer conductor 60. The elastic body 40 is elastically disposed between the insulating base 10 and the base 34.

[0045] It should be emphasized that during the stroke of the movable conductor 30, the central guide rod 20 is always in sliding engagement with the first guide channel 31, and the cylinder 32 is always in sliding engagement with the outer conductor 60. This ensures that the movable conductor 30 can be well protected axially through the double circumferential limiting of the central guide rod 20 and the outer conductor 60, which can effectively prevent the movable conductor 30 from being easily skewed when compressed.

[0046] The outer conductor 60 has a first stop 66 on its outer periphery, and the inner periphery of the cylinder 32 has a second stop 320. The first stop 66 and the second stop 320 are mutually anti-disengagement and limit each other. In addition, the travel of the outer conductor 60 along the cylinder 32 from the first stop 66 to the base 34 is limited to the travel of the movable conductor 30.

[0047] The sliding engagement between the central guide rod 20 and the movable conductor 30 can also be achieved in the manner described in the previous embodiment. Therefore, there is no need for anti-detachment limiting between the outer conductor 60 and the cylinder 32, which will not be elaborated further.

[0048] In this embodiment, the outer conductor 60 and the movable conductor 30 are electrically connected, and the conductive post 50 is electrically connected to the outer conductor 60.

[0049] Based on this, this application also provides a filter, which includes the connector 100 as described above. The connector 100 is disposed on the filter body, the conductive post 50 is electrically connected to the components inside the filter body, the movable conductor 30 is used to electrically connect to the electronic components outside the filter, and the connector 100 can play the roles of conduction and communication, so as to realize the interaction of information and energy between the filter body and the external electronic components.

[0050] Unlike existing technologies, this application discloses a connector and a filter. By providing a first guide channel on the movable conductor, defining a central guide rod that passes through and slides within the first guide channel, and an elastic body fitted onto the central guide rod and elastically positioned between the insulating base and the movable conductor, when the movable conductor is compressed, it can only move back and forth along the axial direction of the central guide rod. The central guide rod provides reliable axial protection to the movable conductor, and the elastic body provides uniform axial support to the movable conductor, further reducing the risk of conductor skewing under stress. This ensures that the movable conductor is not easily skewed when moving along the axial direction of the central guide rod, and effectively guarantees contact between the movable conductor and external communication devices. Therefore, the connector provided by this application effectively improves the situation where the movable conductor is easily skewed when compressed, thus preventing connector damage, improving connector quality, and effectively ensuring the electrical connection performance of the connector.
