Description

Technical Field

[0001] The utility model belongs to the technical field of cable testing, and in particular relates to a cable continuity testing device. Background Art

[0002] Cable is a general term for items such as optical cables and electrical cables. It is a common and indispensable item in daily life. The thickness of the cable mainly depends on factors such as its design purpose, its ability to carry current, and the required mechanical strength. Cables of different thicknesses are suitable for different application scenarios. Thicker cables can usually carry more current and are suitable for high-power transmission or connection; while thinner cables may be more suitable for low-current and low-voltage applications.

[0003] At present, in the cable production process, after making a short cable, it is often necessary to perform a continuity test on the cable to ensure the quality of the product. The traditional detection method is mainly for the staff to hold the insulating part of the detection electrode, and then align the conductor part at both ends of the cable with the detection electrode for connection. At this time, if the cable is normal, a loop is formed to trigger the loop alarm. Otherwise, a complete loop cannot be formed and the alarm is not triggered. However, this traditional detection method is relatively inefficient. Utility Model Content

[0009] As a preferred technical solution, a fixing plate is fixedly connected to the lower end of the mounting plate, and fixing holes are symmetrically opened on the inner side of the fixing plate. The mounting plate can be conveniently installed on the upper end of the base plate through the fixing plate.

[0012] As a preferred technical solution, a sliding hole is opened on the inner side of the limit plate, and the limit plate is slidably connected to the outside of the sliding rod through the sliding hole. A rectangular hole is opened on one side of the inner wall of the through hole, and the end of the insulating block away from the limit plate slides through the rectangular hole. Through the sliding hole, the limit plate can slide conveniently on the inside of the through hole.

When the test electrode contacts the conductor, the test electrode will form a certain elastic extrusion on the cable, so that the test electrode can be tightly attached to the conductor part of the cable, which is convenient for conduction measurement.

[0022] The conducting mechanism 7 includes a mounting hole 702, which is provided on the front side of the base frame 5.

The cable is placed on the positioning seat 1. 0, and then the driving motor 701 is started, so that the output end of the driving motor 701 drives the bidirectional screw 703 to rotate in the mounting hole 702 of the bottom frame 5. Due to the rotation of the bidirectional screw 703, the shifting rods 704 connected with the outer threads can slide close to each other.

The limiting plate 802 connected by the test electrode 9 through the insulating block 805 slides at the sliding rod 803 on the inner side of the through hole 801. When the test electrode 9 contacts the conductor, the test electrode 9 will form a certain elastic extrusion on the cable, so that the test electrode 9 can be tightly attached to the conductor part of the cable, which is convenient for conductivity measurement.
