Moreover, the specific features, structures, materials, or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0034] Please refer to Figures 1 to 2 , Figure 1It is a schematic perspective view of a test component 100 under an embodiment provided by the embodiment of the present utility model; Figure 2 It is Figure 1 A schematic perspective view of the test component 100 from another perspective. The present utility model provides a test component 100 applied to a Fakra connector. The test component 100 includes a test joint 10 and a guide sleeve 20. The test joint 10 includes a test end 11 and a signal end 12. The test end 11 is used to connect with the conductor structure of the Fakra connector, and the signal end 12 is used to connect with the Fakra signal cable. The guide sleeve 20 includes a guiding portion 21. The guiding portion 21 is disposed around the outer periphery of the test end 11, and a chamber 91 is formed between the inner side surface 211 of the guiding portion 21 and the outer side surface 111 of the test end 11. The outer side surface 212 of the guiding portion 21 is used to guide the outer shell of the Fakra connector, so that the shielding tube of the Fakra connector extends into the chamber 91, and the conductor structure of the Fakra connector is connected to the test end 11.

[0035] Specifically, the Fakra connector includes a conductor structure, a shielding tube and an outer shell. The conductor structure is disposed inside the shielding tube, and the shielding tube is disposed inside the outer shell. One of the conductor structure and the test end 11 is a male head, and the other is a female head. The male head and the female head cooperate to achieve electrical connection. Optionally, when the test end 11 is configured as a male head, the signal end 12 is configured as a female head, or when the test end 11 is configured as a female head, the signal end 12 is configured as a male head. It can be understood that the outer side surface 212 of the guiding portion 21 is connected to the inner wall of the outer shell of the Fakra connector, so that the outer shell of the Fakra connector drives the shielding tube and the conductor structure to slide relative to the guiding portion 21, so that the shielding tube of the Fakra connector extends into the chamber 91 between the guiding portion 21 and the test end 11, and at the same time, the conductor structure of the Fakra connector is connected to the test end 11. Compared with the prior art that uses an artificial method for measurement, the present utility model can plug the Fakra signal cable into the signal end 12, and then plug the Fakra connector to be tested into the test end 11. During this process, with the assistance of the guide sleeve 20, it is convenient to align and plug the Fakra connector and the test end 11, and it is not easy to damage the Fakra connector, and it is convenient to realize automated testing and improve the testing efficiency.

[0036] By providing a test adapter 10, the test end 11 of the test adapter 10 is connected to the conductor structure of the Fakra connector, and the signal end 12 of the test adapter 10 is connected to the Fakra signal cable, which is conducive to realizing automated testing and thus improves the testing efficiency. At the same time, by providing a guide sleeve 20, the outer side surface 212 of the guiding portion 21 of the guide sleeve 20 can guide the outer shell of the Fakra connector, so that the shielding tube of the Fakra connector extends into the chamber 91, and the conductor structure of the Fakra connector is connected to the test end 11, thereby reducing the risk of the Fakra connector being damaged.

[0037] In the related art, there are many types of Fakra connectors. The structures of the anti-fooling buckle positions and the fixing buckle positions provided on the outer sides of the outer shells of different Fakra connectors are different. The anti-fooling buckle position is used to cooperate with the anti-fooling structure on the Fakra cable to reduce the occurrence of misinsertion. The fixing buckle position is used to cooperate with the fixing structure on the Fakra cable to relatively fix their positions and prevent the Fakra cable and the Fakra connector from loosening. However, in the test, due to the need for frequent plugging and unplugging (the Fakra connector can be unplugged after the test), the existence of the anti-fooling buckle position and the fixing buckle position of the Fakra connector will reduce the test efficiency.

[0038] In response to this, for the test assembly 100 provided by the embodiment of the present utility model, the outer side surface 212 of the guiding portion 21 is used to guide the inner wall of the outer shell of the Fakra connector. Therefore, the anti-fooling buckle position and the fixing buckle position on the outer side of the outer shell of the Fakra connector can be avoided, and the test efficiency is improved.

[0039] In an embodiment of this embodiment, please refer to Figure 3 , Figure 3 is Figure 1 A schematic cross-sectional view of the test assembly 100 along a section. The test end 11 includes a connecting pipe 15 and a conduction structure 16 provided in the connecting pipe 15. The inner side surface 112 or the outer side surface 111 of the connecting pipe 15 is used to connect to the shielding tube, and the conduction structure 16 is used to connect to the conductor structure. Specifically, when the conduction structure 16 is configured as a female head, the outer side surface 111 of the connecting pipe 15 is used to connect to the shielding tube for ground testing. When the conduction structure 16 is configured as a male head, the inner side surface 112 of the connecting pipe 15 is used to connect to the shielding tube for ground testing. It can be understood that when the outer side surface of the guiding portion 21 is connected to the outer shell of the Fakra connector for guiding, it can ensure that the shielding tube can be inserted into alignment with the connecting pipe 15, thereby ensuring the reliability of the test.

[0040] In an embodiment of this embodiment, please refer to Figure 3, the conduction structure 16 is provided with a contact hole 101 for the conductor structure to extend into for electrical connection. Specifically, in this embodiment, the conductor structure is configured as a male head, and the male head extends into the contact hole 101 to achieve electrical connection. By providing the contact hole 101 on the conduction structure 16, it is convenient to test the conductor structure of the Fakra connector configured as a male head.

[0041] In one embodiment of this implementation manner, please refer to Figure 3 and Figure 4 , Figure 4 is Figure 4 an enlarged structural schematic diagram of the I region of. The inner wall 113 of the contact hole 101 and the end face 114 of the conduction structure 16 are transitioned through a first chamfered surface 115. Specifically, the first chamfered surface 115 is inclined with respect to both the inner wall 113 of the contact hole 101 and the end face 114 of the conduction structure 16, so that the opening of the contact hole 101 is in a shape of inward depression, thereby assisting the conductor structure of the Fakra connector to extend into the contact hole 101 and improving the fault tolerance rate of the test.

[0042] In one embodiment of this implementation manner, please refer to Figure 3 and Figure 4 , there is a spaced distance between the connecting pipe 15 and the end face 213 of the guiding portion 21 facing away from the signal end 12, and there is a spaced distance between the conduction structure 16 and the end face 116 of the connecting pipe 15 facing away from the signal end 12. With such a setting, after the outer shell of the Fakra connector slides a certain distance along the outer side surface of the guiding portion 21, first the shielding pipe and the connecting pipe 15 are connected, and then the conductor structure and the conduction structure 16 are connected, thereby achieving electrical connection and improving the fault tolerance rate of the test.

[0043] In one embodiment of this implementation manner, please refer to Figure 3 and Figure 4 , the end face 213 of the guiding portion 21 facing away from the signal end 12 and the outer side surface 212 of the guiding portion 21 are transitioned through a second chamfered surface 214. Specifically, the second chamfered surface 214 is inclined with respect to both the end face 213 of the guiding portion 21 facing away from the signal end 12 and the outer side surface 212 of the guiding portion 21, that is, in the direction of the signal end 12 facing the test end 11, the thickness of the second chamfered surface 214 corresponding to the guiding portion 21 gradually decreases. With such a setting, the second chamfered surface 214 has a certain guiding effect to improve the fault tolerance rate of the connection between the guiding portion 21 and the outer shell of the Fakra connector.

[0044] In one embodiment of this implementation manner, please refer to Figures 2 to 4, the guide sleeve 20 includes an installation part 22 which is arranged on the outer peripheral side of the signal end 12. The installation part 22 is used to guide the Fakra signal cable so as to facilitate the connection between the Fakra signal cable and the signal end 12. Specifically, in this embodiment, the signal end 12 is configured as a male head, and the Fakra signal cable is configured as a female head. The male head and the female head cooperate to achieve electrical connection. In this embodiment, the test structure includes a contact pin 17. Both ends of the contact pin 17 are located at the guiding part 21 and the installation part 22 respectively. The part of the contact pin 17 located at the guiding part 21 is configured as a female head (provided with a contact hole 101), and the part of the contact pin 17 located at the installation part 22 is configured as a male head.

[0045] In this embodiment, the connecting pipe 15 extends to the signal end 12 to be connected with the shielding pipe of the Fakra signal cable.

[0046] In an embodiment of this implementation manner, please refer to Figure 3 , the installation part 22 is provided with a fixed card slot 221 which is used for clamping with the Fakra signal cable. It can be understood that the Fakra signal cable does not need to be frequently plugged and unplugged from the signal end 12. Generally, when testing the Fakra connector, unless the Fakra signal cable is damaged, it does not need to be unplugged from the signal end 12. By providing the fixed card slot 221 on the installation part 22, the fixed buckle of the Fakra signal cable can be clamped with the fixed card slot 221, so that the Fakra signal cable can be stably connected to the signal end 12.

[0047] In an embodiment of this implementation manner, please refer to Figure 5 , Figure 5 is Figure 1Schematic cross-sectional structure diagram of the test component 100 along another section. The test component 100 includes a first mounting block 31, a second mounting block 32 and a buffer member. The guide sleeve 20 is mounted on the first mounting block 31. The first mounting block 31 is connected to the second mounting block 32 through the buffer member. The second mounting block 32 is used to connect to the base. Specifically, the buffer member includes a screw 33 and a spring 34. The rod portion of the screw 33 is in threaded cooperation with the first mounting block 31. The head of the screw 33 facing the surface of the first mounting block 31 is a conical surface. The second mounting block 32 is provided with a corresponding conical surface, and the two conical surfaces are matched. The spring 34 is sleeved on the rod portion of the screw 33. The two ends of the spring 34 are respectively connected to the first mounting block 31 and the second mounting block 32. The spring 34 is in a compressed state. With such a setting, the first mounting block 31 and the second mounting block 32 can be buffered through the buffer member to avoid hard collision between the test joint 10 and the Fakra connector, resulting in damage to the Fakra connector. Further, by setting the screw 33 and the spring 34, the cooperation between the screw 33 and the second mounting block 32 is a conical surface fit. The spring 34 provides an elastic abutting force between the screw 33 and the second mounting block 32. The first mounting block 31 can float radially and buffer axially relative to the second mounting block 32, further improving the fault tolerance rate of the connection between the test joint 10 and the Fakra connector.

[0048] In an embodiment of this implementation manner, please refer to Figure 1 , the number of test joints 10 is 4. Correspondingly, the guide sleeve 20 covers the 4 test joints 10 and forms chambers 91 with the 4 test joints 10 respectively. In other embodiments, please refer to Figure 6 , Figure 6 is a three-dimensional structure diagram of the test component 100 under another embodiment provided by the embodiment of the present utility model. The number of test joints 10 is 5. Correspondingly, the guide sleeve 20 covers 2 test joints 10. In some other embodiments, the number of test joints 10 can also be other numbers. The present utility model does not specifically limit the number of test joints 10.

[0049] An embodiment of the present utility model provides a testing device, which includes a driving mechanism (not shown) and a testing component 100. The driving mechanism is connected to the testing component 100 and is used to drive the testing component 100 to approach or move away from a Fakra connector, so that the testing end 11 of the testing component 100 is connected to or separated from the Fakra connector. Specifically, the second mounting block 32 is slidably mounted on the base, and the driving mechanism is also mounted on the base. Under the drive of the driving mechanism, the second mounting can drive the first mounting block 31 and the testing joint 10 to slide relative to the base, so that the testing joint 10 approaches or moves away from the Fakra connector. By adding the testing component 100 provided by the embodiment of the present utility model to the testing device, the driving mechanism can cooperate with the testing component 100 to achieve automated testing, thereby improving the testing efficiency. At the same time, the guiding sleeve 20 of the testing component 100 can guide the Fakra connector, reducing the risk of the Fakra connector being damaged.
