Description:
TECHNICAL FIELD 
       [0001]    The disclosure relates to the field of communication, more particularly relates to a connector. 
       BACKGROUND 
       [0002]    With the rapid development of modern mobile communication technology, a new requirement for functions of a connector associated with mobile communication is put forward. For example, there may be a plurality of external input ports or external output ports in an integrated signal transmission system, and a corresponding connector is required for mating by each of the external input ports and the external output port, in order to ensure the signal transmission. In addition, when one of the external input ports and the external output ports is not in use, a corresponding load is also required for absorbing escaping signal in order to prevent interference of the escaping signal. However, absorbing the escaping signal by the corresponding load will increase the volume of the overall structure, and will significantly increase the manufacture cost. In general, a switch connector can be used for preventing interference of the escaping signal. A common switch connector in the prior art is described below. 
         [0003]      FIG. 1  is a structural schematic diagram of a switch connector in the prior art. As shown in  FIG. 1 , the connector includes an inner conductor  11 , an inner conductor  12  and an inner conductor  13 . The connector is also provided with a pressure ring  14  and a spring  15 . In particular, in the case where the connector is unterminated, the inner conductor  11  is not in contact with the inner conductor  12  and in an open state, while the inner conductor  12  is in contact with the inner conductor  13  by the pressure ring  14  and in a close state. In particular, in the case where the connector is terminated, due to the spring  15 , the inner conductor  11  and the pressure ring  14  are pushed downward by a force produced by an interface fit. The inner conductor  11  is in contact with the inner conductor  12  and in a close state, while the inner conductor  12  is separated from the inner conductor  13  and in an open state. The inner conductor  11 , the inner conductor  12 , the inner conductor  13 , the pressure ring  14  and the spring  15  operate together for port selection. The connector being unterminated means that there is no load connected to a connector port, and correspondingly, the connector being terminated means that there is a load connected to the connector port. However, in  FIG. 1 , a selective contact elastic device and the three inner conductors for accomplishing performance transmission are two separate systems, which result in complex structure of the entire connector, miscellaneous small parts, and difficult assembly and performance adjusting. 
         [0004]    There is no efficient solution for solving the problem of complex structure of the connector due to the separation of the performance transmission device and the elastic device of the connector in the prior art. 
       SUMMARY

         [0006]    To this end, a technical solution of an embodiment of the disclosure is realized as follows. 
         [0007]    An embodiment of the disclosure provides a connector including an inner conductor, an outer conductor and an insulating member located between the inner conductor and the outer conductor and forming a non-closed cavity.

         [0008]    In the above solution, in the case where the connector is terminated, the second inner conductor may move towards the first inner conductor and the elastic inner conductor in a vertical direction of the first inner conductor and the elastic inner conductor, until the elastic inner conductor is separated from the first inner conductor and in contact with the second inner conductor. 
         [0009]    In the above solution, in the case where the connector is unterminated, the second inner conductor may be in contact with neither the first inner conductor nor the elastic inner conductor, and the elastic inner conductor may be in contact with the first inner conductor.

In the first state, the elastic member is in contact with the first inner conductor, and in the second state, the elastic member is separated from the first inner conductor and in contact with the second inner conductor. 
         [0012]    In the above solution, the second inner conductor may be movably arranged vertically above the first inner conductor and the elastic inner conductor. 
         [0013]    In the above solution, the elastic inner conductor may include a first inner conductor section, a second inner conductor section and a third inner conductor section. The first inner conductor section may be inclinedly oriented. The second inner conductor section may be horizontally oriented. The third inner conductor section may be vertically oriented. One end of the second inner conductor section may be connected to the bottom end of the first inner conductor section, and the other end of the second inner conductor section may be connected to the top end of the third inner conductor section. 
         [0014]    In the above solution, the first inner conductor may include a fourth inner conductor section, a fifth inner conductor section and a sixth inner conductor section. The fourth inner conductor section and the sixth inner conductor section may be vertically oriented, and the fifth inner conductor section may be horizontally oriented. One end of the fifth inner conductor section may be connected to the bottom end of the fourth inner conductor section, and the other end of the fifth inner conductor section may be connected to the top end of the sixth inner conductor section.

     DETAILED DESCRIPTION 
       [0026]    Technical solutions of the disclosure are described in detail below in connection with the drawings and specific embodiments. It should be noted that embodiments and features therein in this application can be combined with each other when they are compatible. 
         [0027]    In the prior art, inner conductors of a connector are not made of elastic material, and the contact between the inner conductors is accomplished by springs. In other words, the performance transmission device of the connector is separated from the elastic device in the prior art, thereby a structure of the connector is complex. In view of this, a connector is provided by the disclosure, and the structure of the connector is described below. 
         [0028]      FIG. 2  is a structural schematic diagram of a connector according to an embodiment of the disclosure. As shown in  FIG. 2 , the connector includes an inner conductor  1 , an outer conductor  2  and an insulating member  3  located between the inner conductor  1  and the outer conductor  2  and forming a non-closed cavity. An area at an opening of the non-closed cavity is a port selection area. The inner conductor  1  includes: a first inner conductor  40 , a second inner conductor  50  and an elastic inner conductor  60 . The first inner conductor  40  and the elastic inner conductor  60  are arranged in the non-closed cavity; the second inner conductor  50  is arranged in the port selection area; and the elastic inner conductor  60  is selectively in contact with the first inner conductor  40  or the second inner conductor  50 . 
         [0029]    In the above embodiment, one of the conductors of the inner conductor  1  of the connector is an elastic inner conductor  60 . The inner conductor  1  further includes a first inner conductor  40  and a second inner conductor  50 . The elastic inner conductor  60  is selectively in contact with the first inner conductor  40  or the second inner conductor  50 . Therefore, the problem of a complex structure of the connector due to the separation of the performance transmission device and the elastic device of the connector in the prior art is solved. A performance transmission device which may be integrated with the elastic device according to the connector of the embodiment of the disclosure results in less challenging part processing and finished product assembly, a simple structure, an apparent transmission route and a reliable performance and also effectively prevents the interference of the escaping signal. 
         [0030]    The second inner conductor  50  is arranged in the port selection area. The second inner conductor  50  is movably arranged vertically above the first inner conductor  40  and the elastic inner conductor  60  and may alternatively be arranged at other locations as long as the elastic inner conductor  60  can selectively be in contact with the second inner conductor  50 . 
         [0031]    In the case where the connector is unterminated or terminated, the three conductors may be connected in different ways. Specifically, in the case where the connector is unterminated, the second inner conductor  50  is in contact with neither the first inner conductor  40  nor the elastic inner conductor  60 , and the elastic inner conductor  60  is in contact with the first inner conductor  40  due to an elastic arm structure of the elastic inner conductor  60 .  FIG. 3  is a structural schematic diagram of an unterminated connector according to an embodiment of the disclosure. As shown in  FIG. 3 , the elastic inner conductor  60  is in contact with the first inner conductor  40  at an endpoint A, thus a signal pin  70  and a signal pin  80  form a closed-circuit. At the same time, the second inner conductor  50  is separated from the elastic inner conductor  60 , thus the signal pin  80  and a signal source  90  form an open-circuit. 
         [0032]    In the case where the connector is terminated, the second inner conductor  50  moves towards the first inner conductor  40  and the elastic inner conductor  60  in a vertical direction of the first inner conductor  40  and the elastic inner conductor  60 . The elastic inner conductor  60  is separated from the first inner conductor  40  and in contact with the second inner conductor  50 . Because of an elastic arm structure of the elastic inner conductor  60 , after a contact pin of the terminated connector enters into the insulator  3  on the right side of the elastic inner conductor  60 , the second inner conductor  50  is in contact with the elastic inner conductor  60  and makes the elastic inner conductor  60  separated from the first inner conductor  40 , such that the performance transmission device is integrated with the elastic device, and thus a port selection function is achieved, and the performance is more reliable. In addition, one of the conductors of the inner conductor of the connector is an elastic inner conductor, thus a spring device is omitted, the structure of the connector is simpler, and production and maintenance costs are saved. 
         [0033]    The connector herein may be a radio frequency coaxial switch connector. 
         [0034]    In the case where the connector is terminated, it is described in detail below how to realize a port selection function. 
         [0035]      FIG. 4  is a structural schematic diagram of a terminated connector according to an embodiment of the disclosure. As shown in  FIG. 4 , the elastic inner conductor  60  includes an elastic member  61 . In the case where the connector is terminated, the second inner conductor  50  is subjected to an external force, and the elastic inner conductor  60  is changed from a first state into a second state. In the first state, the elastic member  61  is in contact with the first inner conductor  40  at an endpoint A. In the second state, the elastic member  61  is separated from the first inner conductor  40  and in contact with the second inner conductor  50  at an endpoint B. The elastic member  61  may be shaped as shown in  FIG. 4  or alternatively in other forms, as long as the second inner conductor  50  may be in contact with the elastic member  61  when subjected to an external force. 
         [0036]    Shapes of the first inner conductor  40  and the elastic inner conductor  60  are not limited to those shown in  FIG. 4 , but may depends on actual situations. The shapes according to this embodiment are preferably shown in  FIG. 4 . As shown in  FIG. 4 , the elastic inner conductor  60  includes a first inner conductor section  62 , a second inner conductor section  63  and a third inner conductor section  64 . The first inner conductor section  62  is inclinedly oriented, the second inner conductor section  63  is horizontally oriented, and the third inner conductor section  64  is vertically oriented. One end of the second inner conductor section  63  is connected to the bottom end of the first inner conductor section  62 , and the other end of the second inner conductor section  63  is connected to the top end of the third inner conductor section  64 . 
         [0037]    The first inner conductor  40  includes a fourth inner conductor section  41 , a fifth inner conductor section  42  and a sixth inner conductor section  43 . The fourth inner conductor section  41  and the sixth inner conductor section  43  are vertically oriented, and the fifth inner conductor section  42  is horizontally oriented. One end of the fifth inner conductor section  42  is connected to the bottom end of the fourth inner conductor section  41 , and the other end of the fifth inner conductor section  42  is connected to the top end of the sixth inner conductor section  43 . 
         [0038]    The insulating member  3  may be manufactured by processing with mould processing, and an inner conductor is embedded in the mould. The insulating member  3  may be formed in one piece, or alternatively in a plurality of pieces depending on the actual situations. A structural schematic diagram of an insulator is shown in  FIG. 5 , wherein the insulator  3  includes a first insulator  31 , a second insulator  32  and a third insulator  33 . The first insulator  31  is located outside the first inner conductor section  62  and the fourth inner conductor section  41 ; the second insulator  32  is located outside the second inner conductor section  63  and the third inner conductor section  64 ; and the third insulator  33  is located outside the fifth inner conductor section  42  and the sixth inner conductor section  43 . 
         [0039]      FIG. 6  is a structural schematic diagram of an elastic inner conductor according to an embodiment of the disclosure. As shown in  FIG. 6 , an angle of inclination of the second inner conductor section  63  of the elastic inner conductor  60  in a free state with respect to the vertical direction is R. The angle of inclination in  FIG. 3  is changed into a. When a is smaller than β, a certain elastic potential energy would be accumulated, so that the first inner conductor  40  is firmly in contact with the elastic inner conductor  60  at an endpoint A, and a signal connection between the first inner conductor  40  and the elastic inner conductor  60  is accomplished. In this case, a signal pin  70  and a signal pin  80  forms a closed-circuit, and a signal source  90  and the signal pin  80  forms an open circuit. 
         [0040]    In the case where the connector is terminated, as shown in  FIG. 4 , due to an elastic arm of the elastic inner conductor  60 , when the second inner conductor  50  enters into the port selection area, the angle of inclination is further reduced from α to γ. In this case, more elastic potential energy is accumulated, such that the second inner conductor  50  is firmly in contact with the elastic inner conductor  60  at an endpoint B, and a signal connection between the second inner conductor  50  and the elastic inner conductor  60  is accomplished. At this time, due to the reduction of the deflection angle a, the connection is created at the endpoint B instead of the endpoint A, thus the signal pin  70  and the signal pin  80  form an open-circuit, and the signal source  90  and the signal pin  80  form a closed-circuit. 
         [0041]    It can be seen from the above description, the embodiment of the disclosure provides a connector, which preferably is a radio frequency coaxial switch connector. The connector combines the functions of the electrical transmission and elastic arrangement by integrating the performance transmission device and the elastic device, has a firm and stable contact structure, a simple structure and a reliable performance, and prevents the interference of the escaping signal. With the technical solution provided by the embodiment of the disclosure, the connector is very simple in structure, apparent in transmission route, less challenging in part processing and finished product assembly, promising in market prospects, and favorable in social and economic benefits. 
         [0042]    The disclosure is described with the preferred embodiments and is not intended to limit the scope of the disclosure. Any variations, equivalent substitutions and modifications made within the spirit and scope of the disclosure fall in the scope of the disclosure.
