[0033] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0034] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.
[0035] The intermodulation test connector will be described in detail below through specific embodiments:
[0036] Reference Figures 1 to 3 As shown, some embodiments of this application provide an intermodulation test connector, including a first fixing seat 10 and a second fixing seat 20 for supporting the end to be tested 01 and the test end 02.
[0037] A first conductive element and a second conductive element are provided between the first fixing base 10 and the second fixing base 20. The first conductive element and the second conductive element are insulated from each other. The first conductive element is pressed onto the connection between the outer conductor of the end to be tested 01 and the outer conductor of the test end 02. The outer conductor of the end to be tested 01 and the outer conductor of the test end 02 are electrically connected through the first conductive element. The second conductive element is pressed onto the connection between the inner core of the end to be tested 01 and the inner core of the test end 02. The inner core of the end to be tested 01 and the inner core of the test end 02 are electrically connected through the second conductive element.
[0038] In other words, when the first fixing seat 10 and the second fixing seat 20 approach each other, they can gradually press the end to be tested 01 and the test end 02 together. During the pressing process, the end to be tested 01 and the test end 02 can be kept in a fixed position. Under the action of the first conductive element, the outer conductor of the end to be tested 01 and the outer conductor of the test end 02 can be made conductive. Under the action of the second conductive element, the inner core of the end to be tested 01 and the inner core of the test end 02 can be made conductive. This is to test the communication device connected to the end to be tested 01. It can ensure the contact stability between the first conductive element and the outer conductor, and between the second conductive element and the inner core. No additional soldering terminals are required, which is convenient to operate and simplifies the operation steps. Multiple communication devices can be tested by moving the first fixing seat 10 and the second fixing seat 20. It has high versatility and can perform multiple tests, which can improve the testing efficiency.
[0039] In some embodiments, an insulating member is provided between the first conductive member and the second conductive member to isolate the outer conductor and the inner core, ensuring that the outer conductor of the test terminal 01 is electrically connected only to the outer conductor of the test terminal 02, and ensuring that the inner core of the test terminal 01 is electrically connected only to the inner core of the test terminal 02.
[0040] In practice, the insulating component is pressed onto the connection between the insulating medium of the test end 01 and the insulating medium of the test end 02 to ensure the insulation effect between the outer conductor and the inner core.
[0041] Reference Figure 1 As shown, the insulating component includes an upper insulating block 31 and a lower insulating block 32, which are respectively arranged to wrap around the outer periphery of the connection between the insulating medium of the test end 01 and the insulating medium of the test end 02. In other words, the insulating component has a split structure. After the upper insulating block 31 and the lower insulating block 32 are combined, they can wrap around the outer periphery of the connection between the insulating medium of the test end 01 and the insulating medium of the test end 02, so as to isolate the inner core and the outer conductor through the insulating component and ensure the insulation effect.
[0042] Understandably, during connection, cutting off the outer sheath exposes the outer conductor; cutting off part of the outer conductor exposes the insulating medium; and cutting off part of the outer conductor exposes the inner core. The first conductive element connects the outer conductor of the test terminal 01 to the outer conductor of the test terminal 02, and the second conductive element connects the inner core of the test terminal 01 to the inner core of the test terminal 02. Specifically, the first conductive element, the insulating element, and the second conductive element are wrapped layer by layer from the outside in.
[0043] Of course, it should be noted that the insulating component can also be installed on the first fixed base 10 and / or the second fixed base 20 in other ways. This application does not limit this and can be set according to actual needs.
[0044] In other embodiments, the first conductive element and the second conductive element can be insulated by being arranged in a reasonable position, such as by spacing them apart.
[0045] In some embodiments, the first conductive element includes a first upper conductive cotton 41 and a first lower conductive cotton 42 respectively. It can be understood that the first conductive element is formed of conductive cotton material. Under the pressing effect of the first fixing seat 10 and the second fixing seat 20, the first upper conductive cotton 41 and the first lower conductive cotton 42 can be driven to wrap around the outer periphery of the connection between the outer conductor of the end to be tested 01 and the outer conductor of the end to be tested 02, so as to avoid poor contact, ensure conductivity, and adapt to different cables. The circuit can be made conductive by the deformation of the first conductive element.
[0046] In specific implementation, the first upper conductive cotton 41 and the upper insulating block 31 are both disposed on the first fixed base 10, and the first upper conductive cotton 41 and the upper insulating block 31 are disposed adjacent to each other to achieve the positioning of the upper insulating block 31 relative to the first fixed base 10. The first lower conductive cotton 42 is disposed on the second fixed base 20, and the first lower conductive cotton 42 is provided with a first mounting groove 421. The lower insulating block 32 is disposed in the first mounting groove 421 to achieve the positioning of the lower insulating block 32 relative to the second fixed base 20.
[0047] Reference Figure 1 and Figure 2 As shown, the first upper conductive cotton 41 is provided with a first engaging groove 411, and the first lower conductive cotton 42 is provided with a second engaging groove 422. The openings of the first engaging groove 411 and the second engaging groove 422 are arranged opposite to each other to jointly form an outer conductor crimping groove. Specifically, the shape of the outer conductor crimping groove is adapted to the shape of the outer conductor, which improves the contact stability between the outer conductor and the first upper conductive cotton 41, and between the outer conductor and the first lower conductive cotton 42, and ensures the circuit conductivity.
[0048] In some embodiments, refer to Figure 1 and Figure 3 As shown, the second conductive component includes a correspondingly arranged upper conductive cotton 51 and a lower conductive cotton 52. That is, the second conductive component is formed of conductive cotton material. Under the pressing effect of the first fixing seat 10 and the second fixing seat 20, the upper conductive cotton 51 and the lower conductive cotton 52 can be driven to wrap around the outer periphery of the connection between the inner core of the end to be tested 01 and the inner core of the test end 02, so as to avoid poor contact, ensure conductivity, and adapt to different cables. The circuit can be made conductive by the deformation of the second conductive component.
[0049] Specifically, the upper insulating block 31 is disposed on the first fixed base 10, and the upper insulating block 31 is provided with a second mounting groove 311. The second upper conductive cotton 51 is disposed in the second mounting groove 311. The lower insulating block 32 is disposed on the second fixed base 20, and the lower insulating block 32 is provided with a third mounting groove 321. The second lower conductive cotton 52 is disposed in the third mounting groove 321, so as to realize the positioning of the second upper conductive cotton 51 relative to the upper insulating block 31 and the positioning of the second lower conductive cotton 52 relative to the lower insulating block 32.
[0050] Reference Figure 1 As shown, the second upper conductive cotton 51 is provided with a third engaging groove, and the second lower conductive cotton 52 is provided with a fourth engaging groove. The openings of the third and fourth engaging grooves are arranged opposite each other to jointly form the inner core crimping groove. Specifically, the shape of the inner core crimping groove is adapted to the shape of the inner core, which can improve the contact stability between the inner core and the second upper conductive cotton 51, and between the inner core and the second lower conductive cotton 52, and ensure the circuit conductivity.
[0051] It should be noted that the first conductive element and the second conductive element can also be made of other materials. This application does not impose any restrictions on this and can be specifically set according to actual needs.
[0052] In some embodiments, a limiting part 21 is provided on the second fixing base 20, and a through hole 211 is provided on the limiting part 21. The test end 02 is welded and fixed in the through hole 211. With this configuration, during testing, it is not necessary to install or remove the test end 02 multiple times. Multiple communication devices can be tested simply by replacing the end to be tested 01. The inner core and outer conductor of the test end 02 pass through the through hole 211 and are connected to the inner core and outer conductor of the end to be tested 01.
[0053] In practice, the first fixing seat 10 and the second fixing seat 20 can be fixedly connected by fasteners such as screws, thereby pressing the first conductive element to the connection between the outer conductor of the end to be tested 01 and the outer conductor of the test end 02, and pressing the second conductive element to the connection between the inner core of the end to be tested 01 and the inner core of the test end 02, so as to ensure the stability of the connection.
[0054] Understandably, referring to Figure 1 and Figure 2 As shown, the upper insulating block 31 is limited along the axial direction of the cable between the first upper conductive cotton 41 and the limiting part 21, which can ensure the position of the upper insulating block 31 relative to the first fixed seat 10.
[0055] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.
[0056] The above are merely specific embodiments of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to these embodiments, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
