Background technique

In the on-site cable construction, the check of the cable line number must be used. In the step of connecting the line device to the cable in the nuclear line step, it is necessary to peel off the insulation of the cable and then press or connect the line with a terminal block. The terminal of the device is connected to the cable. the

Utility model content

The technical problem to be solved by the utility model is to provide a crocodile clip for electric nuclear wire, which can simplify the line alignment steps in the field cable construction, and specifically can simplify the cable stripping step or only A small amount of cable stripping is required, which reduces the stripping length, saves energy, and improves the overall test efficiency; at the same time, it is convenient for the user to operate the wire aligner with one hand. the

It comprises a long probe made of hard metal between the alligator clip body and the chuck on the alligator clip body. The tail of the long probe is provided with a connection hole for connecting the cable, and the connection hole is provided with a pressing part for pressing and fixing the cable. The pressing part includes a screw rod and a nut, and the long probe is provided with a The screw hole leading from the side wall of the end of the probe to the connection hole, one end of the screw extends into the connection hole through the screw hole and extends with a pressing plate, the other end of the screw rod is installed with the nut, and the long probe has a stepped cylindrical structure , the radius of the stepped cylinder near the end of the chuck is the smallest. The beneficial effect of the above basic scheme is that the cable alignment device reduces the steps of stripping the wires through the use of contact alligator clips, saves energy, and improves the overall test efficiency. One can operate the wire aligner with one hand. The stepped design increases the diameter of the connection between the long probe and the sleeve of the alligator clip body to enhance the fixing effect. It is also easy to cause the tail cable to fall off during rotating contact during use, and the design of the pressing part prevents the tail cable from falling off. the

Further, a handle is provided at the end of the long probe. The handle is designed to facilitate rotation of the long probe, but its shape is not limited thereto, and may also be a structure such as an inverted cone that facilitates rotation of the probe. the

Further, inside the collet of the crocodile clip body, there are a pair of clamping grooves arranged above and below the collet to match the cable to be clamped. The clamping groove is located between the top of the collet of the crocodile clip body and the The long probes are between the end faces inside the alligator clip body. Specifically, the clamping groove is formed by a pair of clamping bases extending from the upper and lower walls of the chuck, and a groove matching the diameter of the cable to be clamped is opened, so that the long probe is facing the clamping hole, and the long probe is avoided. Alignment of needle and core. the

Further, the body of the alligator clip is covered with an insulating jacket. The insulating jacket increases friction and prevents slipping during use. the

Detailed ways

The utility model will be further described in detail below in conjunction with the embodiments and accompanying drawings, but the implementation of the utility model is not limited thereto. the

As shown in Figure 1, it is the crocodile clip for the electric nuclear wire described in the utility model, and the crocodile clip for the electric nuclear wire includes a strip made of hard metal between the crocodile clip body 11 and the chuck on the crocodile clip body Probe 13, said strip probe 13 is threadedly socketed with the sleeve provided in the collet connecting portion 12 of the alligator clip body, and the tail portion of strip probe 13 is provided with a connection hole 15 for connecting cables, on the connection hole A pressing part 16 for pressing and fixing the cable is provided. The pressing part 16 includes a screw and a nut. The long probe is provided with a screw hole leading from the side wall of the end of the probe to the connection hole. One end of the screw is A pressing plate extends through the screw hole into the connecting hole, and the nut is installed at the other end of the screw. When in use, the cable 2 to be aligned is clamped by the chuck on the body of the alligator clip, and the long probe is tightened so that the long probe is in contact with the core of the cable 2 to be aligned. The beneficial effects of the above basic scheme are as follows: The cable alignment device reduces the steps of stripping the wires through the use of contact alligator clips, saves energy and improves the overall test efficiency. At the same time, the terminal can be fixedly connected to the cable, so that people can operate the alignment device with one hand . The stepped design increases the diameter of the connection between the long probe and the sleeve of the alligator clip body to enhance the fixing effect. It is also easy to cause the tail cable to fall off during rotating contact during use, and the design of the pressing part prevents the tail cable from falling off. the

A handle 15 is provided at the end of the strip probe 13 . The handle is designed to facilitate rotation of the long probe, but its shape is not limited thereto, and may also be a structure such as an inverted cone that facilitates rotation of the probe. the
