Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] See Figure 1 This utility model discloses a device for quickly measuring the matching parameters of the retaining ring and the clamping cone of a cable plug, including a wire core, a cable insulation layer 6 outside the wire core, a stress cone 1 sleeved on the cable insulation layer 6, further, a retaining ring 2 is provided at the contact position between the cable insulation layer 6 and the wire core, the retaining ring 2 is tightly attached to the upper section of the cable insulation layer 6, further, a clamping cone 4 is sleeved on the wire core, the clamping cone 4 is tightly attached to the upper end face of the retaining ring 2, a contact motor 3 is sleeved around the clamping cone 4, and a watch strap 5 is sleeved around the contact motor 3.

[0015] Furthermore, insulating lubricating silicone grease is evenly applied to the inner hole of the stress cone 1 and the surface of the cable insulation layer 6.

[0016] The working principle of this utility model is as follows: First, clean the inner hole of the stress cone 1 with a cleaning cloth, or use a hot air gun to dry the inner hole of the stress cone 1. After the solvent has completely evaporated, evenly apply insulating lubricating silicone grease to the inner hole 1 of the stress cone and the surface of the cable insulation layer 6. Then, forcefully fit the stress cone 1 onto the surface of the cable insulation layer 6, leaving a 10-15mm space between the upper end of the stress cone 1 and the end of the cable insulation layer 6. Next, remove the PVC tape on the wire core, clean the surface of the wire core with a cleaning cloth, and then sequentially insert the wire core... The retaining ring 2, the clamping cone 4, the contact electrode 3, and the strap 5 are fitted onto the upper end face of the cable insulation layer 6. The retaining ring 2 is tightly attached to the upper end face of the cable insulation layer 6, and the clamping cone 4 is tightly attached to the upper end face of the retaining ring 2. The contact on the clamping cone 4 is then pre-tightened using a nylon tool. The retaining ring 2 is then clamped with a special assembly tool, and the contact is slowly pressed inward along the cable axis using hydraulic clamps. During the pressing process, it is ensured that the retaining ring 2 is tightly attached to the end face of the insulation layer and the clamping cone 4 is tightly attached to the upper end face of the retaining ring 2. Then the stress cone 1 is retracted and tightly attached to the lower end face of the retaining ring 2 without gaps.
