[0070] Please refer to Figures 1 to 4 and Figures 8 to 12As shown, the shell is a hollow cylindrical member. The shell has a first end 43 located at the upper end and a second end 53 located at the lower end. The lower surface of the first end 43 is located on the upper side of the fixing member 8, and the upper surface of the second end 53 is located on the lower side of the fixing member 8. The two ends of the spring 7 are respectively abutted between the upper surface of the second end 53 and the lower side of the fixing member 8. The cable connector 1 protrudes downward from the lower surface of the second end 53. In an embodiment, the shell is separately arranged. In other embodiments, it can also be an integral arrangement, and the basic structure is similar to that in this embodiment. Here, the separately arranged shell is described in detail. The shell includes an upper shell 4 and a lower shell 5 that are separately arranged. Please refer to Figures 1 to 4 and Figure 8 The upper shell 4 includes the first end 43, an inclined portion 44 extending downward and inward from the first end 43, a support portion 45 extending horizontally inward from the end of the inclined portion 44, a protrusion 41 extending vertically downward from the end of the support portion 45, and a first through hole 42 penetrating the first end 43 and the protrusion 41. The lower shell 5 includes the second end 53, a main body 51 extending upward from the second end 53 and having an outer diameter smaller than the second end 53 and having the gap 6 between the main body 51 and the receiving hole 82 of the fixing member 8, a second through hole 52 penetrating the second end 53 and having an inner diameter smaller than the inner diameter of the main body 51, a support end 54 located at the upper end of the main body 51, and a support end outer wall surface 541 located outside the support end 54. The inner diameter of the spring 7 is larger than the outer diameter of the main body 51. The protrusion 41 is inserted into the second through hole 52 so that the protrusion 41 is located inside the main body 51. The abutting end 54 abuts against the abutting portion 45. The gap 6 is provided between the abutting end outer wall surface 541 and the vertical wall surface 84 provided on the fixing member 8. In the first embodiment, it is preferred that the outer diameter of the first end portion 43 is equal to the outer diameter of the second end portion 53, both of which are 12.6 mm.

[0071] The second step portion 35 is pressed downward against the upper surface of the second end portion 53 , and the first step portion 34 is pressed downward by the protruding portion 41 , thereby fixing the cable connector 1 between the upper shell 4 and the lower shell 5 .

[0072] Please refer to Figures 1 to 4 and Figures 8 to 12 As shown, the fixing member 8 is a plate-shaped structure. The fixing member 8 includes a plate body 81, a receiving hole 82 located at the center of the plate body 81, a guide portion 83 located at the upper end portion of the receiving hole 82, and a vertical wall surface 84 located at the lower end portion of the receiving hole 82.

[0073] Please refer to Figures 10 to 12As shown, when the test connector assembly 100 is used, the test connector assembly 100 is aligned with the docking connector 200 in the vertical direction, and then the test connector assembly 100 is moved downward toward the docking connector 200 as a whole, and the plug-in portion 112 is inserted into the docking connector 200, so that the conductive terminal 12 and the metal shell 14 are electrically connected with the docking connector 200, thereby testing the working state of the docking connector 200. At this time, the fixing member 8 compresses the spring 7 downward, and the upper shell 4 is separated from the fixing member 8 upward. The spring 7 is compressed and elastically deformed. When it is necessary to separate the test connector assembly 100 from the docking connector 200, the elasticity of the spring 7 can help the separation of the two. During the docking process, the gap 6 between the shell and the vertical wall 84 allows the shell to swing horizontally, which is conducive to the test connector assembly 100 aligning with the docking connector 200 and docking smoothly. The guide portion 83 and the inclined portion 44 help the upper shell 4 return to the initial position.

[0074] Please refer to Figures 13 to 17 As shown, in the second embodiment of the present invention, the difference from the first embodiment is that the test connector assembly 100' is used to test a docking connector 200' having two rows of signal groups. The test connector assembly 100' comprises two insulating bodies 11', two rows of conductive terminals 12' respectively fixed to the two insulating bodies 11', two groups of cables 15' respectively electrically connected to the two rows of conductive terminals 12', two first grounding members 21' having grounding ends 212' and an intermediate grounding plate 9 disposed between the two insulating bodies 11'. The two insulating bodies 11' and the intermediate grounding plate 9, both of which are fixed with the conductive terminals 12', are assembled together and the plastic housing 13' fixed with the metal housing 14' is integrally sleeved. Then, the two first grounding members 21' and the two groups of cables 15' are welded. The intermediate grounding plate 9 is electrically connected to the ground of the cables 15'. The remaining structures of the housing 3', the upper housing 4', the lower housing 5', the gap 6', the spring 7' and the fixing member 8' are the same as those of the first embodiment.

[0075] The seven conductive terminals 12 of the first embodiment of the present invention have several signal terminals, preferably, they can be arranged in the form of one signal terminal, one ground terminal, one signal terminal, one ground terminal, one signal terminal, one ground terminal and one signal terminal, or in the form of one signal terminal, two ground terminals, one signal terminal, two ground terminals and one signal terminal. The arrangement of the two rows of conductive terminals 12' in the second embodiment of the present invention can be the same as that in the first embodiment. Thus, the test connector assembly 100, 100' of the present invention can detect docking connectors 200, 200' with multiple signals. The electrical connection between the cable connector 1, 1' and the cable 15, 15' in the first and second embodiments of the present invention does not use a circuit board, so that the overall structure is simple, easy to manufacture, and the cost is reduced.
