Description
Technical Field
The utility model relates to the technical field of steel-cored aluminum stranded wires, in particular to a single wedge type strain clamp for a steel-cored aluminum stranded wire.
Background
The steel core aluminum cable or steel core aluminum wire is used in overhead electric wire, steel wire with high tension is used as the core of the wire, aluminum wire is wound around the wire for supplying electricity, and aluminum wire is used as the outer layer, so that the aluminum wire has good conductivity, light weight and low cost. The inner layer uses steel wires because of its strong tension. Unfortunately, although the electrical conductivity of steel wires is poor, most of the current passes through the outer layer of the cable due to the skin effect. Therefore, the inner layer has poor conductivity, which is not the case, and the higher the inner layer resistance is, the better.
Currently, as in the patent publication CN204046106U, a strain clamp is disclosed, which includes a housing having a wedge-shaped cavity, a hanger plate assembly, and a left wedge core and a right wedge core disposed in the wedge-shaped cavity; the hanging plate assembly comprises a left hanging plate, a right hanging plate and a bolt fastening assembly; the left side wall of the shell is provided with a left side screw hole, the right side wall of the shell is provided with a right side screw hole, the left side bolt is in threaded connection with the left side screw hole, and the right side bolt is in threaded connection with the right side screw hole; the left side face of the left wedge core is provided with a first groove corresponding to the left screw hole, and the right side face of the right wedge core is provided with a second groove corresponding to the right screw hole. Because of the existence of the first groove and the second groove, the left wedge core can not scrape the inner end edge of the left screw hole in the moving process, and the right wedge core can not scrape the inner end edge of the right screw hole in the moving process, so that the left wedge core and the right wedge core can be guaranteed to be installed in place, and the wire clamping effect is guaranteed.
The main beneficial effects that produce are: in the strain clamp, the left side surface of the left wedge core and the right side surface of the right wedge core are provided with the material saving grooves, so that the material can be effectively saved and the production cost can be reduced on the premise of ensuring the performance of a product. In the strain clamp, the limiting structure can enable the left wedge core and the right wedge core to synchronously move in the wedge-shaped cavity, and can prevent the left wedge core and the right wedge core from relatively rotating in the moving process and in place during installation. In the strain clamp, the limiting structure comprises the limiting plate and the limiting hole matched with the limiting plate, and after the limiting plate is in plug-in fit with the limiting hole, the left wedge core and the right wedge core can be ensured to synchronously move and cannot relatively rotate; the limiting structure of the utility model has simple and feasible structure, saves materials and reduces the production cost. In the strain clamp, the strength of the left hanging plate and the right hanging plate can be increased by arranging the reinforcing ribs, and the inverted teeth are arranged in the wire grooves of the left wedge core and the right wedge core, so that the cable can be effectively prevented from sliding relatively with the left wedge core and the right wedge core by arranging the inverted teeth, the direction of the inverted teeth is opposite to the advancing direction of the cable, the insulating layer of the cable is firmly grasped, and the wire clamping effect is ensured.
The technical problems which are mainly solved by the utility model are as follows: (1) The hanging plate is connected with the shell through a bolt, and the left clamping plate (corresponding to a left wedge core in the application) and the right clamping plate (corresponding to a right wedge core in the application) are scraped with the left clamping plate and the right clamping plate at the inner end edge of a threaded hole in threaded connection with the bolt on the shell in the process of being inserted into the wedge-shaped cavity, so that the left clamping plate and the right clamping plate are difficult to install in place due to friction resistance, and the clamping effect of the left clamping plate and the right clamping plate on the cable is further affected; (2) Through set up the spacing boss in left side that has a left side and stop the face on the tip face of left side splint, set up the spacing boss in right side that has a right side and stop the face on the tip face of right side splint, still set up interlocking linkage structure in addition (including establish draw-in groove on left side splint and set up on right side splint with draw-in groove complex cardboard), thereby through adopting above-mentioned structure make left side splint and right side splint can under the exogenic action wedge intracavity synchronous movement to prevent that left side splint and right side splint from taking place relative rotation in wedge intracavity, so, make the structure of left side splint and right side splint comparatively complicated, be unfavorable for saving materials, increased manufacturing cost.
For the description of the above patent, the applicant believes that although the applicant solves the corresponding technical problem, the technical solution still has drawbacks in other respects, in particular as follows:
in the process of working and using the single-wedge type strain clamp for the existing steel-cored aluminum strand wire, the single-wedge type strain clamp needs to be installed firstly, and when the single-wedge type strain clamp is installed, the single-wedge type strain clamp is relatively complicated, workers are required to install by means of other parts such as screw nuts, the labor capacity of the workers can be increased, and meanwhile after the single-wedge type strain clamp is used for a long time, the single-wedge type strain clamp can easily fall off and other phenomena occur.
