[0016] The utility model is now further described with reference to the accompanying drawings.

[0017] See also Figure 1The utility model provides a coaxial signal shielding line quick-insert measurement fixture, including a base 1, a spring 2, a slider 3, a clamping device 4, a quick-insert connector 5, a clamping bolt 6, a clamping nut 7, a quick-insert male head 8, a quick-insert female head 9, a pressing plate 10 and a limiter 11. The clamping device 4 is arranged on the inner bracket of the base 1, a clamping bolt 6 is arranged below the hinge of the clamping device 4, the clamping bolt 6 is connected to the clamping nut 7 through a thread, and below the clamping nut 7 is a pressing plate 10 fixed by a spring 2 and a slider 3, the spring 2 passes through the pressing plate 10 and is arranged on the periphery of the slider 3, the bottom of the slider 3 is connected to the base 1, the top of the slider 3 is arranged with a limiter 11 located above the pressing plate 10, the bottom of the pressing plate 10 is arranged with a quick-insert connector 5 connected with the mounting hole on the pressing plate 10, and the base 1 is provided with a quick-insert male head 8 and a quick-insert female head 9.

[0018] A test chip is arranged on the base 1 just below the pressing plate 10 .

[0019] The limiting members 11 are laterally symmetrically arranged on the pressing plate 10 .

[0020] The number of mounting holes on the pressing plate 10 is 3.

[0021] Working principle:

[0022] The utility model does not require much debugging when working. After the coaxial shielded wire is inserted into the mounting hole on the pressure plate 10, it can be further inserted into the quick-insertion connector 5. The other end of the shielded wire is inserted into the quick-insertion male connector 8, so as to clamp the shielded wire. The quick-insertion male connector 8 is electrically connected to the quick-insertion female connector 9 through the circuit inside the base 1, and the quick-insertion female connector 9 is then connected to the test equipment. When testing is required, the clamping device 4 is pulled, and the downward pressure is transmitted to the clamping bolt 6 under the drive of the hinge, and the clamping and fixing are achieved through the clamping nut 7 and the pressure plate 10. The pressure plate 10 slides down along the slider 3. When the quick-insertion connector 5 is close to the test chip below, the shielded wire exposed from the bottom of the quick-insertion connector 5 contacts the test chip to complete the test. At this time, under the rebound action of the spring 2, the slider 3 drives the pressure plate 10 to rebound upward until it is blocked by the limiter 11. At this time, the test signal is transmitted to the quick-insertion female connector 9 through the quick-insertion male connector 8 and then transmitted to the external test equipment to complete the test. Since the quick-plug connector 5, the quick-plug male connector 8 and the quick-plug female connector 9 are all quick-plug interfaces, the shielded wire can be quickly pulled out along with the pressure plate 10 without damaging the cable and thus affecting the test, and the pressure plate 10 will not damage the shielded wire during the up and down reciprocating motion.
