In particular, referring to fig. 1, a test plug is provided that includes a cable 100 and a jacket assembly; the front end of the cable 100 is welded and fixed with the probe 101, the cable 100 is wrapped by the outer sleeve component to form effective protection for the cable, the probe 101 extends out of the outer sleeve component, and when the cable is used, the probe 101 can be conducted only by being completely inserted into the M12 connector.

In traditional design, be provided with locking nut in the test plug, be equipped with the external screw thread simultaneously on the outer circular wall of M12 connector, in order to guarantee that test plug can carry out stable grafting with the M12 connector, often need the spin locking nut to carry out the spin with the external screw thread and close. There are fifteen M12 connectors provided in the socket device, so in order to ensure the normal of each M12 connector, a tester needs to test the different M12 connectors one by using the test plug. Long-time screwing tests can lead to thread abrasion of the locking nut, and unstable connection in subsequent tests can influence stability of test results.

For the above reasons, we have changed the traditional fastening connection mode of screwing; specifically, in this embodiment, a clamp member 20 is sleeved on the outer sleeve member, the clamp member 20 has at least two clamp bodies 21 capable of relatively moving, and the clamp bodies 21 are configured to clamp on the surface of the M12 connector; the probe 101 is quickly plugged into and out of the M12 connector via the clamp 20.

In the scheme, the traditional thread screwing mode is replaced by a clamp-type connecting mode, so that the purposes of simplifying operation, testing efficiently and reducing wear rate are achieved.

In particular, referring to fig. 2, the clamp member 20 mentioned above also comprises a collar 22, which collar 22 is sleeved in the outer sleeve assembly and is freely movable through 360 ° in the circumferential direction; the clamp body 21 is connected to the surface of the collar 22, and the clamp member 20 is internally provided with high-elasticity memory metal reinforcing ribs which are convenient for rebound and plasticity.

It will be appreciated that the clamping member 20 herein works in much the same manner as a conventional spring clip in life; the elastic clamp can keep elastic clamping under the action of a spring (or a pressure spring), and the clamp piece 20 in the scheme can keep certain elastic clamping under the action of a high-elasticity memory metal reinforcing rib, so that the clamp body 21 can be stably clamped on the M12 connector.

To improve stability after clamping, the distal end of each clamp body 21 is provided with a saw tooth structure by which the clamp body 21 can engage with the threads on the outer surface of the M12 connector. That is, the structure of the M12 connector is not changed, and the design of external threads still remains on the outer surface of the M12 connector; in the scheme, a saw tooth structure is designed at the distal end of the clamp body 21 and is matched with the thread on the outer surface of the M12 connector; when the plugging conduction test is carried out, the sawtooth structure is directly meshed with the thread on the outer surface of the M12 connector, so that the loose of the test connector in the test process can be effectively avoided.

Meanwhile, in the scheme, a new structural design is also carried out on the outer sleeve component; specifically, referring to fig. 3 to 5, the outer jacket assembly includes a front cap 11, an insulation sleeve 12, a needle sleeve 13, a binding ring 14, a rubber ring 15, and a tail cap 16 in this order from front to rear.

The front cap 11 comprises a head and a barrel, and the head and the barrel are coaxially fixed and form a ladder structure; an external thread is arranged on the cylinder body, and a blank area is formed between the external thread and the stepped structure; the collar 22 of the clamp 20 is essentially sleeved in the empty space, and the rotatable connection with the front cap 11 is realized; an internal thread is provided in the tail cap sleeve 16; the tail cap 16 and the front cap 11 are fastened by screwing the internal and external threads while the clamp member 20 is restrained in the front cap 11.

In the scheme, the front cap sleeve 11 is a metal sleeve; the insulating sleeve 12 is sleeved inside the metal sleeve; so that the probe 101 passes out of the insulating sleeve 12 and does not contact the front cap 11. Meanwhile, a guide groove 111 is arranged in the front cap 11, and the outer surface of the insulating sleeve 12 is provided with a first guide post 121 which protrudes outwards; the insulating sleeve 12 is in plug-in fit with the guide groove 111 through the first guide post 121 so as to complete positioning and fixing of the insulating sleeve 12 in the front cap 11.

The needle sleeve 13 is used for fixing and clamping the probe 101, so that the probe 101 can be stably inserted into the M12 connector; specifically, the probe 101 passes through a needle slot in the needle hub 13; the needle sheath 13 is here built into a central hole in the insulating sheath 12.

Optionally, the needle grooves in the needle sleeve 13 are marked with numbers, each number corresponds to a different probe 101, so that the probes 101 can be quickly ordered and inserted and fixed when the test plug is assembled.

Optionally, the insulating sleeve 12 and the needle sleeve 13 are made of plastic insulating materials, so that short circuit and conduction phenomena can be avoided.

Meanwhile, in this embodiment, the probe 101 is fixed in the binding ring 14 by welding; the outer surface of the binding ring 14 has a convex second guide post 141, wherein the second guide post 141 is configured to be inserted into the guide groove 111. It can be understood that, when the test plug is assembled, the first guide post 121 and the second guide post 141 can be abutted in the guide groove 111 to complete guide guiding, so as to ensure the smoothness of the assembling process.

Optionally, the outer sleeve assembly further comprises a rubber ring 15, the rubber ring 15 is built in the binding ring 14, and the cable 100 passes through the tail cap sleeve 16 and the rubber ring 15 until being connected with the probe 101 welded on the binding ring 14; the tail cap sleeve 16 is screwed to enable the tightening ring 14 to be contracted with the rubber ring 15 so as to fix the cable 100 and prevent the cable 100 from loosening.

In addition, the present solution also provides a method for testing an M12 connector by adopting the test plug, referring to fig. 6 to fig. 7, including:

the tail end of the probe 101 of the test plug is connected with a test device through a welding cable 100, wherein the cable 100 is a network cable, and the test device is a network communication test device. The probe 101 head is inserted in alignment with the M12 connector hole site.

And secondly, directly clamping the external thread of the tested M12 connector by loosening the two ends of the clamp body 21 of the test plug, so that the saw tooth structure on the clamp body 21 is engaged and clamped with the external thread.

And thirdly, transmitting signals to test equipment through the cable 100 of the test plug, and carrying out communication and various tests through the equipment to complete the test work.
