Description

Cable clamping anti-loosening fastener

Technical Field

The utility model relates to a limiting device, in particular to a cable clamping anti-loosening clamping piece.

Background

The existing cable is usually clamped by a wire pressing plate on a cable socket (as shown in fig. 8), so that the cable is prevented from being broken at a wiring position due to the fact that the cable is run out or dragged, however, the existing cable socket is poor in clamping effect, the existing cable socket can be loosened due to repeated dragging under the complex working condition environment (the existing cable socket is still in reference to the standard of the safety of GB4706.1 household and similar appliances, the standard is low in cable anti-dragging loosening requirement, the cable is still very easy to loosen at the wire pressing plate and the cable sheath is very easy to break due to repeated dragging), the cable cannot be continuously clamped for a long time, and the cable is not clamped at the cable sheath of the existing cable socket due to the fact that the cable pressing plate breaks the cable sheath if the cable is dragged in different directions, so that the cable is not beneficial to long-term use and the risk of electric leakage is also caused.

The Chinese patent No. 210272806U discloses an improved structure of a socket, which is to compress a cable by adopting a cable pressing plate, so that the cable cannot be continuously and loose-proof and can be compressed for a long time.

The utility model solves the technical problems by adopting the technical scheme that: the cable clamping anti-loosening fastener comprises a clamping seat, wherein an inserting hole is formed in the clamping seat, a socket is inserted in the clamping seat, a group of notches are formed in the clamping seat and uniformly distributed along the center of the clamping seat, first elastic plates are fixed on the notches, clamping hooks are fixed on the top ends of the first elastic plates, through holes are formed in the clamping seat, a group of second elastic plates surrounding the through holes are fixed on the edges below the through holes, a pressing mechanism for pressing the second elastic plates to close to each other is arranged on the socket, a limiting plate with a section larger than that of the socket is fixed on the bottom surface of the socket, and the clamping seat and the socket are fixed together through fasteners. The clamping seat and the socket have the function that the socket can be plugged into the clamping seat for matching; the notch, the first elastic plate and the clamping hook have the function of enabling the clamping hook to be clamped on the matched part through the elasticity of the first elastic plate for fixing (shown in fig. 7); the perforating hole, the second elastic plate and the pressing mechanism have the functions that when the socket is in plug-in fit with the clamping seat, the pressing mechanism can press the cable passing through the perforating hole; the limiting plate has the function of limiting the clamping seat and the socket fixed together by the fastener on the matched part, so that the movement of the clamping piece is avoided.

Further perfecting, the pressing mechanism comprises inclined planes which are arranged on the outer contour surfaces of the second elastic plates, V-shaped structures with small lower parts and large upper parts are arranged between the inclined planes, and taper holes which are used for pressing the inclined planes and enabling the second elastic plates to be close to each other are arranged on the socket. The inclined surfaces and the taper holes have the effect that the inclined surfaces on the second elastic plates can be directly pressed by the taper holes in the process of inserting and matching the socket into the clamping seat, so that the second elastic plates can be mutually closed to clamp the cable.

Further perfecting, radial clamping blocks are fixed on the inner sides of the bottoms of the second elastic plates. The radial clamping blocks here have the effect of being able to clamp the cable more firmly.

Further perfecting, the top end on the socket is fixed with a group of baffles, and each baffle is used for blocking between the first elastic plate and the notch and is attached to the inner side end surface of the first elastic plate. The baffle plate has the advantages that when the buckle piece is installed at the matched part, the baffle plate can be utilized to prevent the first elastic plates from being buckled to be loosened, so that the condition that the buckle piece is loosened due to human factors is avoided, and the cable is not loosened.

The beneficial effects of the utility model are as follows: the clamping device is ingenious and reasonable in structural design, the socket can be spliced on the clamping seat to be matched by utilizing the clamping seat and the socket, the clamping hook can be clamped on the matched part by utilizing the notch, the first elastic plate and the clamping hook through the elasticity of the first elastic plate, the through hole, the second elastic plate and the pressing mechanism can be used for pressing a cable penetrating through the through hole when the socket is spliced on the clamping seat, the clamping seat and the socket which are fixed together by utilizing the fastening piece can be limited on the matched part by utilizing the limiting plate, the movement of the clamping piece is avoided, the cable is clamped and loose, the cable is not damaged due to dragging, the installation and the maintenance are facilitated, and the clamping device is worthy of popularization and application.
