[0002] As wireless communications develop towards 5G, multi-channel systems have become a trend. Compared with traditional 2T / 2R and other RRU (Remote Radio Unit) modules, multi-channel systems increase the number of channels to 64 / 128 channels, with strong demands for high frequency, high performance and low cost. An integrated antenna architecture is adopted in the multi-channel system. The integrated antenna architecture includes stacked RF boards and antenna boards, in which the antenna boards and the RF boards are connected by RF blind plug connectors for signals. However, when adopting an integrated antenna architecture, due to the size changes, warping and installation positioning methods of the RF board, structural parts and antenna board itself, higher requirements are placed on the tolerance capability of the blind plug connector. The existing blind plug connectors can no longer guarantee the reliability during connection. Summary of the invention

[0011] In a specific implementable solution, the outer side wall of the conductive sleeve is dotted to form a circle of inwardly concave grooves, and the inwardly concave grooves form a circle of protrusions on the inner side wall of the conductive sleeve for defining the sliding connector.
[0012] In a specific feasible solution, the connector further comprises an insulating sleeve, and the insulating sleeve is sleeved outside the conductive sleeve, thereby improving the safety of the entire connector.
[0013] In a specific feasible solution, a groove for accommodating the conductive head is provided at the end of the insulating sleeve, and the sliding connector can be located in the groove when it is contracted.
[0014] In a specific implementable solution, among the two connectors, one connector is the sliding connector, and the other connector is a fixed connector fixedly connected to the conductive sleeve.

[0031] The embodiments of the present application will be further described below in conjunction with the accompanying drawings.
[0032] First, let's explain the application scenarios of connectors. As an electrical connection device, connectors are used in the field of antennas. Figure 1 A specific connector application scenario shown in Figure 1 The integrated antenna includes a stacked RF board 5, a structural member 4 and an antenna board 3, wherein the structural member 4 is located between the RF board 5 and the antenna board 3. The structural member 4 serves as a supporting structure for supporting the RF board 5 and the antenna board 3. The RF board 5 and the antenna board 3 are functional parts of the integrated antenna, and the RF board 5 is provided with a circuit layer including a feed source, which is used to transmit signals to the antenna board 3, or receive signals received by the antenna board 3. A radiation unit 2 is provided on the antenna board 3, and a circuit layer electrically connected to the radiation unit 2 is provided on the surface of the antenna board 3. A connector 1 is passed through the structural member 4, and the connector 1 is used to connect the circuit layer on the RF board 5 with the circuit layer on the antenna board 3, so as to realize electrical connection between the feed source and the radiation unit 2. When assembling the above structure, due to the influence of warping or assembly error between the plates of the RF board 5 and the antenna board 3, errors may occur between the RF board 5 and the antenna board 3. In particular, as the antenna performance requirements become higher and higher, the requirements for the contact points between the RF board 5 and the antenna board 3 are also increasing, resulting in an increasing number of connectors 1 required, which in turn affects the stability of the connector 1 in electrically connecting the antenna board 3 to the RF board 5. For this purpose, an embodiment of the present application provides a connector 1. The following is a detailed description of it in conjunction with specific drawings and embodiments.
[0033] For the convenience of description, direction a is introduced, and direction a is the direction from the RF board to the antenna board.
[0034] Figure 2 The schematic diagram of the connector structure is shown. The connector 100 includes a main structure 10 and two connectors. For the convenience of description, the two connectors are named as a first connector 20 and a second connector 30. The length of the main structure 10 is along the direction a. The first connector 20 and the second connector 30 are located at both ends of the main structure 10. Figure 1 In the application scenario of the connector shown in , the first connector 20 can be used for conductive connection with the antenna board, and the second connector 30 can be used for conductive connection with the radio frequency board.
[0035] Figure 3The cross-sectional view of the connector is shown. The main structure 10 includes a conductive sleeve 11, which is a cylindrical structure with a length along the direction a, and is hollow inside and open at both ends. The first connector 20 and the second connector 30 are assembled in the hollow cavity of the conductive sleeve 11, and the first connector 20 and the second connector 30 are respectively conductively connected to the conductive sleeve 11.
[0036] To ensure the stability of the electrical connection between the RF board and the antenna board. The connector 100 provided in the embodiment of the present application has a certain degree of floating. Exemplarily, the first connector 20 can be slidably connected to the conductive sleeve 11 and can slide back and forth along the direction a; the second connector 30 is fixedly connected to the conductive sleeve 11. At this time, the first connector 20 serves as a sliding connector that is slidably connected to the conductive sleeve 11, and the second connector 30 serves as a fixed connector that is fixedly connected to the conductive sleeve 11. When the first connector 20 slides relative to the conductive sleeve 11, the length of the connector 100 in the direction a can be changed, thereby ensuring the stability of the connection between the RF board and the antenna board.
[0037] The number of specific sliding connectors is not limited in the present application, and at least one of the two connectors only needs to be a sliding connector that is slidably assembled in the conductive sleeve 11. In addition to the assembly method described above, the assembly method of the first connector 20 and the second connector 30 can also be: the first connector 20 is slidably connected to the conductive sleeve 11 and can slide along the direction a, and the second connector 30 is slidably connected to the conductive sleeve 11 and can slide along the direction a; or, the first connector 20 is fixedly connected to the conductive sleeve 11, and the second connector 30 is slidably connected to the conductive sleeve 11 and can slide along the direction a. Different connection methods can all achieve changing the length of the connector 100 in the direction a and achieving a floating connection of the connector 100.
[0038] When any one of the first connector 20 and the second connector 30 is used as a sliding connector, the elastic member 40 is used as a driving member to push the sliding connector to slide relative to the conductive sleeve 11. The elastic member 40 is arranged in the sleeve and can be elastically deformed along the direction a. When the elastic member 40 is elastically deformed, the elastic force of its own elastic deformation can be used as a driving force to drive the connector to slide. The following takes the first connector 20 as a sliding connector and the second connector 30 as a fixed connector as an example to illustrate the setting method of the elastic member 40 provided in the embodiment of the present application. The setting method of the elastic member 40 provided in the embodiment of the present application includes but is not limited to the following fixing methods: one end of the elastic member 40 is fixedly connected to the conductive sleeve 11, and the other end is pressed against the sliding connector; or one end of the elastic member 40 is pressed against the fixed connector, and the other end is pressed against the sliding connector.
[0039] In an optional solution, the elastic member 40 can be a compression spring, elastic rubber or disc spring, etc. Exemplarily, the elastic member 40 can be a compression spring, which is located in the conductive sleeve 11, and the two ends of the compression spring are pressed against the two connectors one by one. When the above setting is adopted, the compression spring is convenient to set.
[0040] In addition to the above-mentioned conductive sleeve 11, the main structure 10 may also include an insulating sleeve 12. The conductive sleeve 11 is entirely wrapped outside the insulating sleeve 12 to electrically isolate the conductive sleeve 11 from external devices and improve the safety of the conductive sleeve 11. Figure 1 In the application scenario shown, the insulating sleeve 12 is also used to form a link impedance of 50 ohms with the structural member when the connector is assembled into the antenna.
[0041] Figure 4 The conductive sleeve 11 can be made of copper, aluminum or other materials to form a cylindrical structure, and the two ends of the conductive sleeve 11 opening are respectively a first end and a second end.
[0042] refer to Figure 4 The dotted line in Figure 4 The dotted lines in the figure do not represent the actual structure of the conductive sleeve 11, but are only schematic lines for artificially dividing the regions for the convenience of description. The conductive sleeve 11 is divided into the following regions along its length: a conductive connection region, a limiting region, and a containing region. For example, Figure 4 As shown in , the conductive sleeve 11 is divided into: a first conductive connection area A, a first limiting area B, a containing area C, a second limiting area D and a second conductive connection area E in sequence along its length direction. The first conductive connection area A is located at the first end of the conductive sleeve 11, and the second conductive connection area E is located at the second end of the conductive sleeve 11; the first conductive connection area A is used for conductive connection with the first connector, and the second conductive connection area E is used for conductive connection with the second connector. The first limiting area B is used to limit the sliding distance of the first connector, and the second limiting area D is used to fix the second connector to the conductive sleeve 11. The containing area C is used to accommodate the elastic member. It should be understood that the above division is only a rough division of the conductive sleeve 11 for the convenience of description, and does not represent that the conductive sleeve 11 is an actual structure.
[0043] When the first connector slides relative to the conductive sleeve 11 along direction a, it is necessary to ensure that the electrical connection stability between the first connector and the conductive sleeve 11 is maintained during the sliding process. To this end, an elastic claw 111 for pressing against the first connector is provided on the conductive sleeve 11, and the elastic claw 111 is located in the first conductive connection area A. One end of the elastic claw 111 is connected to the conductive sleeve 11, and the other end is a free end. When the elastic claw 111 is in a free state, the size of the opening surrounded by the free end of the elastic claw 111 is smaller than the lateral size of the portion where the first connector is electrically connected to the conductive sleeve 11. When the first connector is assembled into the conductive sleeve 11 and slides, the elastic deformation of the elastic claw 111 can be used to make the free end of the elastic claw 111 always press against the first connector, thereby ensuring the stability of the connection between the first connector and the conductive sleeve 11. The above-mentioned lateral size refers to the size of the edge of the cross section of the first connector when the first connector is cut transversely by a plane perpendicular to the direction a where the opening surrounded by the free end of the elastic claw 111 is located.
[0044] In an optional solution, the number of elastic claws 111 may be at least two. Exemplarily, the number of elastic claws 111 is two, three, four or other different numbers. By adopting multiple elastic claws 111, the contact points between the first connector and the conductive sleeve 11 are increased, and the stability of the electrical connection between the first connector and the conductive sleeve 11 is improved.
[0045] In an optional solution, the elastic claw 111 may be a structure formed by opening a notch 112 at the first end of the conductive sleeve 11 . In this case, the elastic claw 111 and the conductive sleeve 11 are integrated into one structure, thereby ensuring the structural strength of the elastic claw 111 .
[0046] In order to prevent the first connector from sliding out of the conductive sleeve 11 under the drive of the elastic member, a first limiting area B is divided on the conductive sleeve 11 to cooperate with the first connector to limit the maximum distance of the first connector sliding along the direction a. In an optional scheme, a protrusion is set on the conductive sleeve 11 to limit the sliding distance of the first connector, and it is named as the first protrusion 113 for the convenience of description. The first protrusion 113 is located in the first limiting area B, and the first protrusion 113 can be formed in different ways. Exemplarily, the first protrusion 113 can be a plurality of protruding points protruding into the conductive sleeve 11 formed on the side wall of the conductive sleeve 11, and the plurality of protruding points are arranged around the conductive sleeve 11 in a circle 3; or a circle of concave grooves can be formed on the outer wall of the conductive sleeve 11, and the concave grooves form the first protrusion 113 on the inner side of the conductive sleeve 11.
[0047] The structure of the second limiting area D is similar to that of the first limiting area B, and also forms a circle of dotted dots to form a circle of inwardly concave grooves. The inwardly concave grooves are protruded on the inner side of the conductive sleeve 11. The protrusion is named as the second protrusion 114. The second protrusion 114 can fix the second connector to the second end of the conductive sleeve 11 and electrically connect to the conductive sleeve 11. The above-mentioned second limiting area D and second protrusion 114 can be used as optional components. When the second connector and the conductive sleeve 11 are independent structures, the second connector can be fixed to the conductive sleeve 11 through the above-mentioned second protrusion 114; when the second connector and the conductive sleeve 11 are an integrated structure, the second limiting area D and the second protrusion 114 are not required.
[0048] exist Figure 4 The conductive sleeve shown in the figure is cylindrical, but the shape of the conductive sleeve 11 is not limited in the present application, and may also be in different shapes such as an elliptical cylinder, a polygonal cylinder, etc. When the conductive sleeve 11 adopts different shapes, the corresponding first connector and the second connector inserted into the conductive sleeve 11 need to be adapted to the shape of the conductive sleeve 11. For example, when the conductive sleeve is cylindrical, the first connector and the second connector inserted into the conductive sleeve 11 are also cylindrical.
[0049] Figure 5 The schematic diagram of the first connector and the conductive sleeve is shown. First, the structure of the first connector 20 is described. The first connector 20 includes a limit portion 21 and a connection portion 22 arranged along direction a. The limit portion 21 and the connection portion 22 are fixedly connected. The connection portion 22 is used to electrically connect to the conductive sleeve. Figure 5 As shown, the connection portion 22 is partially located inside the conductive sleeve 11 and partially exposed outside the conductive sleeve 11. The portion outside the conductive sleeve 11 is used for antenna board connection. The size of the opening surrounded by the free ends of the elastic claws 111 is smaller than the lateral size of the connection portion 22. Therefore, when the first connector 20 is assembled, the port surrounded by the elastic claws 111 is expanded, and the free ends of the elastic claws 111 are elastically deformed to ensure that the elastic claws 111 are always pressed against the connection portion 22. The connection portion 22 has a certain length in direction a. When the first connector 20 slides relative to the conductive sleeve 11, the length should ensure that the connection portion 22 is always pressed against the elastic claws 111.
[0050] The limiting portion 21 is used to cooperate with the corresponding first protrusion 113. When set, the limiting portion 21 is located at the end of the first connector 20 inserted into the conductive sleeve 11 and is located below the first protrusion 113 (with Figure 5The placement direction of the connector in the figure is taken as a reference reverse direction). The lateral dimension of the limiting portion 21 is larger than the dimension of the opening surrounded by a circle of first protrusions 113, so as to ensure that when the limiting portion 21 slides to the first protrusion 113, the limiting portion 21 can be limited by the first protrusion 113 to prevent the first connector 20 from sliding out of the conductive sleeve 11.
[0051] In an optional solution, the first connector 20 includes a conductive head 23 exposed in the conductive sleeve 11, and the size of the conductive head 23 is larger than the size of the end opening of the conductive sleeve 11 to prevent the entire conductive head 23 from being retracted into the conductive sleeve 11. The conductive head 23 and the connecting portion 22 can be connected in different ways. For example, the conductive head 23 and the connecting portion 22 are detachably connected, such as interference fit between the conductive head 23 and the connecting portion 22, or connected by threads; or the conductive head 23 and the connecting portion 22 can also be an integral structure.
[0052] Figure 6 The structure of the first connector is shown, and the shape of the first connector 20 is adapted to the shape of the conductive sleeve. The first connector 20 includes: a limit portion 21, a connecting rod 24, a connecting portion 22 and a conductive head 23 along direction a; wherein the connecting rod 24 is used as a connecting piece between the connecting portion 22 and the limit portion 21, and the lateral dimension of the connecting rod 24 is smaller than the dimension of the opening surrounded by the first protrusion to ensure the sliding effect of the first connector 20. In an optional scheme, the connecting portion 22, the connecting rod 24 and the limit portion 21 can be used to form a structure with a thin middle and thick ends, and the sliding distance of the first connector 20 in the conductive sleeve is limited by the connecting portion 22 and the limit portion 21. It should be understood that the above-mentioned limit portion 21, the connecting rod 24 and the connecting portion 22 can be separate components, and the components form the first connector 20 through interference fit or threaded fit; or, the above-mentioned limit portion 21, the connecting rod 24 and the connecting portion 22 can also be an integrated structure to reduce the connection between the components and improve the conductive performance of the first connector 20.
[0053] Combination Figure 5 and Figure 6 When the first connector 20 is assembled to the conductive sleeve 11, after the limiting portion 21, the connecting rod 24 and the connecting portion 22 are inserted into the conductive sleeve 11, the first protrusion 113 is formed on the side wall of the conductive sleeve 11 by mortise and tenoning, the limiting portion 21 and the connecting portion 22 are located on both sides of the first protrusion 113, and the connecting rod passes through the opening surrounded by the first protrusion 113. When the above assembly method is adopted, the first connector 20 is assembled conveniently, and the limiting portion is formed after the assembly is completed, thereby ensuring the matching effect between the first protrusion 113 and the limiting portion 21.
[0054] The conductive head 23 is an optional component. The end surface of the conductive head 23 away from the connecting portion 22 is used to contact the antenna board or the RF board. The end surface can be in different shapes, such as an arc surface, a plane or a cone surface. When the conductive head is not provided, the antenna board or the RF board can be contacted through the connecting portion 22.
[0055] Figure 7 The structure of the second connector is shown. The shape of the second connector 30 matches the shape of the conductive sleeve. The second connector 30 is fixedly connected to the conductive sleeve and is electrically connected to the conductive sleeve when fixedly connected. Figure 4 and Figure 7 The second connector 30 has a limiting groove 31 that matches the second protrusion 114 in the second limiting area D. During assembly, the second connector 30 is inserted into the second conductive area E and extends into the second limiting area D. After that, the second protrusion 114 is formed at the second limiting area D, and the second protrusion 114 is clamped into the limiting groove 31, so that the second connector 30 is fixed to the second end of the conductive sleeve 11 and electrically connected to the conductive sleeve 11. The conductive head 32 of the second connector 30 is exposed outside the conductive sleeve, and serves as a connector connected to the antenna board or the RF board.
[0056] Figure 8 The structure of the insulating sleeve is shown. The insulating sleeve 12 is used to protect the conductive sleeve and electrically isolate it. The insulating sleeve 12 can be made of insulating materials such as rubber, plastic, and resin. During assembly, the insulating sleeve 12 is sleeved on the outside of the conductive sleeve, and a cavity for inserting the conductive sleeve is provided inside the insulating sleeve 12. In addition, a groove for accommodating a conductive head is also provided at the end of the insulating sleeve 12, which can be located in the groove when the first connector is contracted and press-contact with the conductive head of the first connector to avoid excessive squeezing of the first connector by the antenna board or the radio frequency board when assembled into the antenna.
[0057] In an optional solution, at least one end of the insulating sleeve 12 is provided with a boss structure, and the boss structure is used to form a 50 ohm link impedance with the structural member when the connector is assembled into the antenna. Exemplarily, the first boss structure 121 and the second boss structure 122 are respectively provided at both ends of the insulating sleeve 12, and a 50 ohm link impedance is formed with the structural member through the first boss structure 121 and the second boss structure 122.
[0058] To facilitate the connector provided in the embodiment of the present application, the following is combined Fig. 9 and Fig.10 The first connector 20 and the second connector 30 of the connector are pressed against the RF board and the antenna board respectively to achieve electrical connection between the RF board and the antenna board. Fig. 9As shown, when the connector is in a free state, the first connector 20 is pushed by the elastic member 40 to be exposed outside the conductive sleeve 11, and the limiting portion 21 presses against the first protrusion 113. Fig.10 As shown in FIG. 1 , under the action of external force, the first connector 20 is pressed into the conductive sleeve 11 and the elastic member 40 is compressed. Fig. 9 and Fig.10 It can be seen that the conductive link on the connector is always turned on regardless of whether the connector is compressed or in a free state. Taking the current flowing from the first connector 20 to the second connector 30 as an example, the conductive link is: the current flows from the first connector 20, is transmitted to the conductive sleeve 11 through the connection between the first connector 20 and the elastic claw 111, and is transmitted to the second connector 30 through the connection between the conductive sleeve 11 and the second connector 30, thereby ensuring the connection effect between the RF board and the antenna board.
[0059] When applying the connector to an integrated antenna, ensure that the connector is in Fig.10 to ensure that the connector has a certain contact pressure with the RF board and antenna board.
[0060] When there is warping or assembly error between the radio frequency board and the antenna board, the elastic member 40 can ensure that the connector electrically connects the two. In addition, the connector uses the limiter 21 to separate the conductive connection part, effectively realizing the separation of electrical contact and mechanical anti-detachment function, the reliability of the connection between the structural parts with the mechanical anti-detachment function will not affect the reliability of the electrical connection parts, and the electrical connection effect between the first connector and the conductive sleeve 11 is improved by the elastic claw 111, thereby greatly improving the reliability of the electrical connection of the connector.
[0061] Fig.11 An antenna provided in an embodiment of the present application is shown, and the antenna is an integrated antenna. The antenna includes a stacked RF board 200, a structural member 300 and an antenna board 400. The structural member 300 is located between the RF board 200 and the antenna board 400, and serves as a supporting structure. The RF board 200 and the antenna board 400 are arranged on opposite sides of the structural member 300. The RF board 200 and the antenna board 400 are functional parts of the integrated antenna, and the RF board 200 is provided with a circuit layer including a feed source, which is used to transmit signals to the antenna board 400, or receive signals received by the antenna board 400. A radiation unit 401 is provided on the antenna board 400, and a circuit layer electrically connected to the radiation unit 401 is provided on the surface of the antenna board 400. The structural member 300 is provided with a through hole for penetrating the connector 100, and the lateral dimension of the through hole is larger than the lateral dimension of the connector 100, and the connector 100 can move freely in the through hole. The connector 100 is used to connect the circuit on the radio frequency board 200 with the circuit layer on the antenna board 400 to achieve electrical connection between the feed source and the radiation unit 401 .
[0062] During assembly, one connector of the connector 100 is connected to the RF board 200, and the other connector is connected to the antenna board 400. By sliding the connector in the connector 100, the connector 100 is floated in the direction a, ensuring that the connector 100 can electrically connect the RF board 200 to the antenna board 400. In addition, by separating the limiting portion of the connector 100 from the conductive connection portion, the electrical contact and mechanical anti-detachment functions are effectively separated, greatly improving reliability. When the RF board 200 and the antenna board 400 are affected by the warping or assembly errors between the plates, the connection effect of the RF board 200 and the antenna board 400 can be guaranteed by changing the length of the connector 100, thereby ensuring the reliability of the integrated antenna. Even when the antenna performance requirements are getting higher and higher, and the contact points between the RF board 200 and the antenna board 400 are also increasing, when multiple connectors 100 are used, the connection effect of the RF board 200 and the antenna board 400 can still be guaranteed.
[0063] Fig.12 Another antenna mechanism provided by an embodiment of the present application is shown. The antenna is an integrated antenna. The antenna includes a stacked RF board 200, a filter module 500 and an antenna board 400. The filter module 500 is a cavity filter, and the cavity filter is located between the RF board 200 and the antenna board 400. The RF board 200 and the antenna board 400 are arranged on opposite sides of the cavity filter. The RF board 200 and the antenna board 400 are functional parts of the integrated antenna, and the RF board 200 is provided with a circuit layer including a feed source, which is used to transmit a signal to the antenna board 400, or to receive a signal received by the antenna board 400. A radiation unit is provided on the antenna board 400, and a circuit layer electrically connected to the radiation unit is provided on the surface of the antenna board 400. The cavity filter is used to filter the clutter in the signal transmitted from the RF board 200 to the antenna board 400, or from the antenna board 400 to the RF board 200. The connector 100 is used to connect the circuit on the RF board 200 with the circuit layer on the antenna board 400 to realize the electrical connection between the feed source and the radiation unit.
[0064] During assembly, the connector 100 is divided into two layers. One layer is located between the antenna board 400 and the RF module, and is used to connect the antenna board 400 and the RF module. One connector of the connector 100 is connected to the filter module 500, and the other connector is connected to the antenna board 400. The other layer of connector 100 is located between the RF module and the RF board 200. One connector of the connector 100 is connected to the filter module 500, and the other connector is connected to the RF board 200. When the above scheme is adopted, the floating of the connector 100 in direction a is achieved by sliding the connector in the connector 100, ensuring that the connector 100 can electrically connect the RF board 200 to the antenna board 400. In addition, by using the limit portion of the connector 100 to separate the conductive connection portion, the electrical contact and mechanical anti-detachment functions are effectively separated, greatly improving reliability.
