Description

Technical Field

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

[0002] HSD connectors (High Speed ​​Data connectors) are widely used in the communications and automotive industries for high-speed signal and current transmission. In existing technologies, such as... Figure 7 As shown, when testing the high-frequency quality of an HSD connector (connector 11' under test), a double-ended PCB board (first PCB board 101' and second PCB board 102') is typically used for conversion. This testing method results in too many test conversions, leading to poor accuracy in product signal quality testing and making it impossible to directly capture high-frequency quality data such as return loss of the HSD sample 11' under test. Furthermore, due to batch consistency factors in PCB manufacturing processes, group test results vary significantly. Additionally, the PCB board conversion scheme has significant limitations on product types and lacks versatility. Utility Model Content

[0003] The purpose of this application is to provide a connector test adapter cable to address the shortcomings of the prior art.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] A connector test adapter cable, comprising:

[0006] A port, which connects to a connector under test, includes an insulator, multiple port cores disposed within the insulator, an outer conductor disposed outside the insulator, and a housing disposed outside the outer conductor.

[0007] Multiple coaxial cables are provided, each corresponding one-to-one with a port core material.

[0012] In some embodiments, the rear end of the port core material is cylindrical, and the core wire of the coaxial cable is inserted into the rear end of the port core material.

[0013] In some embodiments, the coaxial cable has a covering shell on its outer side and a stripping section at a predetermined distance at its front end. The covering shell of the stripping section is stripped off to expose the outer conductor of the coaxial cable. The outer conductor of the stripping section is connected to the outer conductor of the port.

[0014] In some embodiments, the outer conductor of the port is cylindrical, the coaxial line is inserted into the outer conductor of the port from the rear end, and the stripping section abuts against the inner wall of the outer conductor of the port.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] This application provides a connector test adapter cable. For example... Figures 1 to 4 As shown, in this embodiment, the connector test adapter cable 10 includes a port 100 and multiple coaxial cables 200. The port 100 is used to connect to the connector under test 11, and the coaxial cables 200 are used to connect to the test equipment 12.

[0033] like Figures 1 to 3 As shown, port 100 includes an insulator 110, multiple port core materials 120, a port outer conductor 130, and a housing 140. (As...) Figure 3As shown, the port core 120 is disposed within the insulator 110. In this embodiment, the connector test adapter 10 is used to test a four-core twisted-pair port HSD connector; therefore, as... Figure 3 As shown, in this embodiment of the application, the connector test adapter cable 10 has four port cores 120, and the four port cores 120 are connected one-to-one with the four cores of the HSD connector under test. Figure 3 and Figure 4 As shown, the four port core materials 120 are all arranged along the axial direction of the port 100, and the four port core materials 120 are parallel to each other. Specifically, as... Figure 5 As shown, four axially extending through holes 111 can be provided in the insulator 110, and four port cores 120 are inserted into the through holes 111, thereby installing the port cores 120 into the insulator 110. The front end of the port core 120 is used to connect to the core of the connector 11 under test, and the rear end of the port core 120 is used to connect to the core wire 210 of the coaxial cable 200.

[0034] like Figures 2 to 4 As shown, the port outer conductor 130 is disposed outside the insulator 110, and the insulator 110 separates and insulates the port core material 120 and the port outer conductor 130. It can be understood that the port outer conductor 130 is made of metal and serves as grounding and shielding.

[0035] The housing 140 is disposed outside the outer conductor 130 of the port. The housing 140 is made of insulating material such as plastic, serving to protect the connector under test 11 and to secure it in place. The housing 140 is provided with a snap-fit ​​structure to snap into place with the connector under test 11.

[0036] like Figure 2 As shown, multiple coaxial cables 200 correspond one-to-one with the multiple port cores 120 of port 100. The coaxial cables 200 are connected to the rear end of port 100. Each coaxial cable 200 has a core wire 210 and an outer conductor 220, which are insulated from each other. The core wire 210 of the coaxial cable 200 is connected to the port core 120 of port 100, and the outer conductor 220 of the coaxial cable 200 is connected to the port outer conductor 130 of port 100. The rear end of the coaxial cable 200 is connected to a test device 12 for testing the connector under test.

[0037] The connector 11 under test is tested using the connector test adapter cable 10 described above. Simply plug the port 100 of the connector test adapter cable 10 into the connector 10 under test, and connect the coaxial cable 200 of the connector test adapter cable 10 to the corresponding interface on the test equipment 12. This avoids the need for a double-ended PCB board 101 for conversion, reduces the conversion and transition between the connector and the test equipment 12, and is highly versatile, easy to operate, has low loss, low test error, and high test accuracy. Figure 7This refers to the testing scheme in the existing technology. Figure 8 This is a test scheme for an embodiment of this application, for comparison. Figure 7 and Figure 8 It can be seen that the test scheme of this application embodiment has fewer transitions and shifts.

[0038] refer to Figure 4 The outer conductor 220 of the coaxial cable 200 is welded or crimped to the outer conductor 130 of the port 100. Specifically, for example... Figure 4 The outer conductor 220 of the coaxial cable 200 is inserted into the outer conductor 130 of the port. The outer side of the outer conductor 220 of the coaxial cable 200 is welded or riveted to the inner wall of the outer conductor 130 of the port. In this embodiment, the outer conductor 220 of the coaxial cable 200 is welded or riveted to the outer conductor 130 of the port 100, resulting in a stable and reliable connection with low overall loss and strong anti-interference capability.

[0039] As a preferred option, such as Figure 4 As shown, the outer conductor 220 of the coaxial cable 200 and the outer conductor 130 of the port 100 are soldered together. Figure 4 After welding, a solder layer 221 is formed between the outer conductor 220 of the coaxial line 200 and the outer conductor 130 of the port 100.

[0040] like Figure 2 As shown, a coaxial port 300 is provided at the rear end of the coaxial cable 200. Figure 6 As shown, the coaxial port 300 includes a nut connector 310, a coaxial port core material 320, and a coaxial port insulator 330. The coaxial port core material 320, coaxial port insulator 330, and nut connector 310 are arranged sequentially from the inside out. The coaxial port core material 320 is connected to the core wire 210 of the coaxial line 200. One end 310a of the nut connector 310 is connected to the outer conductor 220 of the coaxial line 200, and the other end 310b is provided with an external thread 311. The external thread 311 is used to connect to the test equipment 12, ensuring a secure connection between the coaxial port 300 and the test equipment 12. During connection, the nut connector 310 is tightened onto the connection port or connection wire port of the test equipment 12. It is understood that the test equipment 12 connected to the coaxial port 300 is provided with an internal thread that matches the external thread 311 of the nut connector 310.

[0041] like Figure 5As shown, the rear end 120b of the port core material 120 is cylindrical. Setting the rear end 120b of the port core material 120 to a cylindrical shape facilitates the insertion of the core wire 210 of the coaxial cable 200 into the rear end 120b of the port core material 120 to connect the port core material 120. After the core wire 210 of the coaxial cable 200 is inserted into the rear end 120b of the port core material 120, it can be further fixed to the port core material 120 through processes such as welding, preventing separation of the core wire 210 of the coaxial cable 200 from the port core material 120 and ensuring the reliability of the connection.

[0042] like Figure 5 As shown, the front end 120a of the port core 120 can also be set as cylindrical to facilitate insertion with the connector under test 11.

[0043] like Figure 2 As shown, the coaxial cable 200 has a covering shell 230 on its outer side, and a stripping section 201 with a predetermined distance at its front end. The covering shell 230 of the stripping section 201 is peeled off, thereby exposing the outer conductor 220 of the coaxial cable 200. Figure 2 As shown, the outer conductor 220 of the stripping section 201 is exposed, facilitating the connection of the outer conductor 220 of the stripping section 201 to the outer conductor 130 of the port 100. For example... Figure 4 As shown, after the stripping section 201 is inserted into the outer conductor 130 of the port 100, the exposed outer conductor 220 of the stripping section 201 can contact the inner wall of the outer conductor 130 of the port to connect.

[0044] Combination Figure 4 and Figure 5 As shown, the outer conductor 130 of port 100 is cylindrical. (As indicated...) Figure 4 As shown, the coaxial cable 200 is inserted into the outer conductor 130 of the port from the rear end of the outer conductor 130. The stripping section 201 at the front end of the coaxial cable 200 contacts the inner wall of the outer conductor 130 of the port, thereby making the outer conductor 220 of the coaxial cable contact the outer conductor 130 of the port. Then, it can be further fixed by riveting or welding.

[0045] refer to Figure 8 The test steps for using the connector test adapter cable 10 of this application are as follows:

[0046] Solder the connector under test 11 onto the PCB board 101, and connect the interface on the PCB board 101 to the corresponding interface on the test device 12.

[0047] Connect the port 100 of the connector test adapter cable 10 of this application to the connector 11 under test, and connect two of the four coaxial cables 200 of the connector test adapter cable 10 of this application to the corresponding interfaces on the test equipment 12 to start the test;

[0048] After the test is completed, replace the other two of the four coaxial cables 200 of the connector test adapter cable 10 in this application with the corresponding interfaces on the test equipment 12, and start the test;

[0049] In the above test, the four cores of the four-core twisted-pair HSD connector 11 are divided into two differential pairs to transmit signals separately. During the test, the two differential pairs are tested separately. Of course, if the test equipment 12 allows, the two differential pairs can also be tested simultaneously.

[0050] The technical features in the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments described above merely illustrate the implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
