[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] This utility model provides a test module for high-frequency performance transmission of vehicle connectors, comprising: a housing for connecting the connector under test to the wiring harness interface, a high-frequency connector, and a positioning component. The housing has one or more cavities that extend from front to back, and the high-frequency connector is disposed within the cavity. The housing has a vertically extending positioning hole, and the outer wall of the high-frequency connector has a positioning groove corresponding to the position of the positioning hole. The positioning component is detachably inserted into the positioning hole and the positioning groove to fix the housing and the high-frequency connector.

[0007] In use, the test module of this application connects one end to the connector under test (DUT) and the other end to the wire harness interface. The high-frequency connector enables the connection between the DUT and the wire harness interface, thereby achieving the connectivity of the entire test system and enabling the transmission of high-frequency signals. During signal transmission, it can detect whether the DUT can stably and efficiently transmit high-frequency signals. Simultaneously, the positioning component secures the housing and the high-frequency connector, thereby improving the structural stability of the test module.

[0008] Furthermore, the positioning element is a pin.

[0009] Further, four cavities are provided, and the four cavities are arranged in a "field" shape. Four high-frequency connectors are provided, and the four high-frequency connectors are respectively arranged one-to-one in the four cavities. The positioning member is inserted between the four high-frequency connectors.

[0010] Further, the housing includes a test connection head and a test connection seat. One end of the test connection head has a first mating connector for connecting to the tested connector, and the other end has a first mating interface; one end of the test connection seat has a second mating connector, and the other end has a second mating interface for connecting to the wire harness interface; the first mating interface is docked with the second mating connector, and the positioning hole penetrates through the walls of the first mating interface and the second mating connector up and down.

[0011] Further, the shapes of the first mating interface and the second mating connector are adapted to each other, so as to achieve the effect of pre-positioning and ensure that there is no misalignment after assembly.

[0012] Further, the inner wall of the first mating interface has a pressing portion for pressing the high-frequency connector, which can press the high-frequency connector to ensure that the high-frequency connector does not move, so as to ensure the stability of the test.

[0013] Further, the first mating connector adopts a profiling structure adapted to the shape of the tested connector. Even if the position deviates during the mating process, it can be accurately inserted into the tested connector to complete the automated test.

[0014] Further, the second mating interface adopts a profiling structure adapted to the shape of the wire harness interface, and a clamping hole is also provided on the inner wall of the second mating interface, which can ensure that the buckle of the wire harness interface can be accurately clamped into the clamping hole of the second mating interface, ensure that the wire harness does not fall off after mating, and ensure the stability of the test.

[0015] Further, the high-frequency connector has a docking end that can be docked with the tested connector, and the docking end has a docking hole. When the high-frequency connector is docked with the tested connector, the signal pin of the tested connector can be clamped and fixed through the docking hole, so as to improve the connection stability, and further ensure the stability of the test.

[0016] Further, a fixing sleeve is sleeved on the docking end. The fixing sleeve is made of an elastic material, and the end of the fixing sleeve has more than one slot.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] To achieve the above objectives, the technical solution of this utility model is as follows:

[0025] See Figures 1-4As shown in the figure, this embodiment provides a test module for high-frequency performance transmission of a vehicle-mounted connector, including: a housing 1, a high-frequency connector 2, and a positioning member for connecting the connector under test and the wiring harness interface. The positioning member is a pin 3. The housing 1 has more than one cavity 4 that penetrates through from front to back, and the high-frequency connector 2 is arranged in the cavity 4. A positioning hole 5 that penetrates through from top to bottom is provided on the housing 1, and a positioning groove 6 corresponding to the position of the positioning hole 5 is provided on the outer wall of the high-frequency connector 2. The pin 3 is detachably inserted into the positioning hole 5 and the positioning groove 6 to fix the housing 1 and the high-frequency connector 2.

[0026] When the test module of the present application is in use, one end is docked with the connector under test, and the other end is docked with the wiring harness interface. The high-frequency connector 2 can connect the connector under test and the wiring harness interface, thereby realizing the connection of the entire test system and the transmission of high-frequency signals. During the signal transmission process, it can be detected whether the connector under test can stably and efficiently transmit high-frequency signals. At the same time, the pin 3 can fix the housing 1 and the high-frequency connector 2, thereby improving the structural stability of the test module.

[0027] Further, there are four cavities 4, and the four cavities 4 are arranged in a "field" shape. There are four high-frequency connectors 2, and the four high-frequency connectors 2 are respectively arranged one by one in the four cavities 4. The pin 3 is inserted between the four high-frequency connectors 2.

[0028] Further, the housing 1 includes a test connection head 11 and a test connection seat 12. One end of the test connection head 11 has a first plug connector 111 for connecting the connector under test, and the other end has a first plug interface 112. One end of the test connection seat 12 has a second plug connector 121, and the other end has a second plug interface 122 for connecting the wiring harness interface. The first plug interface 112 is docked with the second plug connector 121, and the positioning hole 5 penetrates through the walls of the first plug interface 112 and the second plug connector 121 from top to bottom.

[0029] Through the above structural settings, the disassembly and assembly between the test connection head 11 and the test connection seat 12 can be realized by the pin 3, and further, the number of high-frequency connectors 2 used can be adjusted, which is convenient for switching among 1-4 high-frequency connectors 2.

[0030] Further, the shapes of the first plug interface 112 and the second plug connector 121 are adapted to each other, so as to achieve the effect of pre-positioning and ensure that there will be no misalignment after assembly.

[0031] Furthermore, the inner wall of the first mating interface 112 has a clamping part 113 for clamping the high-frequency connector 2, which can clamp the high-frequency connector 2 to ensure that the high-frequency connector 2 does not move, thereby ensuring the stability of the test.

[0032] In this application, the positioning hole 5 is a concentric hole that passes through the test connector 11 and the test connector 12. The pin 3 can pass through the concentric hole, pass through the test connector 11 and the test connector 12 vertically, and pass through the positioning grooves 6 of the four high-frequency connectors 2 to achieve a precise connection between the test connector 11, the test connector 12, and the high-frequency connectors 2. It also works with the clamping part 113 to achieve a secondary fixation of the high-frequency connectors 2.

[0033] Furthermore, the first pair of connectors 111 adopts a contour-following structure that matches the shape of the connector under test, so that even if the position is offset during the mating process, it can be accurately inserted into the connector under test to complete the automated test.

[0034] Furthermore, the second plug-in interface 122 adopts a contoured structure that matches the shape of the wire harness interface. The inner wall of the second plug-in interface 122 is also provided with a locking hole 123, which can ensure that the buckle of the wire harness interface can be accurately locked into the locking hole 123 of the second plug-in interface 122, ensuring that the wire harness will not fall off after plugging and ensuring test stability.

[0035] Furthermore, the high-frequency connector 2 has a mating end 21 capable of mates with the connector under test, and the mating end 21 has a mating hole 22. When the high-frequency connector 2 mates with the connector under test, it can clamp and fix the signal pins of the connector under test through the mating hole 22, thereby improving the stability of the connection and ensuring the stability of the test.

[0036] Furthermore, a fixing sleeve 23 is fitted onto the mating end 21. The fixing sleeve 23 is made of elastic material, and its end has one or more slots 24. When the high-frequency connector 2 mates with the connector under test, the fixing sleeve 23 can use elastic deformation to open the slot 24 structure outward, thereby allowing the fixing sleeve 23 to fit tightly against the inner wall of the outer conductor of the connector, firmly fixing the mating end 21 to the connector under test, thus ensuring the stability of the test.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
