CN203722043U - Lifting and plucking pliers for preventing fatigue break of cable - Google Patents

Abstract

The utility model discloses lifting and plucking pliers for preventing the fatigue break of a cable, and the lifting and plucking pliers comprise a clamping head, a locking device, a shell, a driving rod, and handles. The clamping head is fixed with a pull rod through a locking mechanism on the pull rod. The locking device comprises a locking sleeve, a steel ball, a stop ring, and a spring. The locking device is fixed in the shell by the stop ring at the front end of the pull rod and the spring at the rear end of the locking sleeve through the pull rod. The handles are connected to the pull rod and the shell by an elastic pin through the driving rod. The front end of the shell is a hollow cylinder, and the rear end of the shell is a rectangular shoulder rack. The cylinder at the front end is partitioned into one-sixth raised keys which are distributed uniformly. In work, the handles at two sides are closed, thereby driving the driving rod so as to drive the pull rod to move backwards along the axial direction of the shell, and carrying out height-limiting pulling-out operation for a connector with a cable. The lifting and plucking pliers can solve the problems that the pulling-out impact force of a conventional tool is excessive during the debugging and maintaining of the connector with the cable, and the fatigue break of the cable is easy to happen in a pulling-out process.

Description

A kind of group pincers that rise that prevent the electric cable splitting for fatigue

Technical field

The one that relates to the utility model rises and dials pincers, is specifically related to a kind of group pincers that rise that prevent the electric cable splitting for fatigue.

Background technology

In the radio circuit of wireless device and electronic instrument, coaxial cable is often fixed by two terminal adapters.Two terminal adapters are co-axial cable components that a kind of curved formula pushes stopping type, are made up of connector and a middle coaxial cable at two ends.Two terminal adapters are that curved formula pushes the cable assembly that connects hard (rigidity) cable in the middle of the co-axial cable component of stopping type, have that volume is little, lightweight, reliability high, are applicable to wireless device.

In the debugging and maintenance process of coaxial cable, two terminal adapters often need to plug from complete machine.Owing between two terminal adapters being usually harder cable, conventional plug-pull tool clamps the method such as extract for sticking up thick stick separate type, step bayonet type, tweezers, first pulls out a terminal adapter of cable assembly, is then pulling out other one end.Owing to pulling out the bad control of time of releasing impulsive force, impact distance of connector in place's process, often easily there is the excessive cable that pulls for cable hard or that flexibility is bad, thereby cause the problem of distortion of the cable or fracture.If two terminal adapters on than the integrated plate of comparatively dense, adopt hand or common pliers to plug very inconvenient, more easily cause cable bend and rupture.Constantly causing cable bend increased frequency in plug process, cause the root fatigue fracture of cable in addition, will affect the electrical property of cable assembly, to such an extent as to cable assembly is scrapped, increase production cost, made troubles to debugging and maintenance work simultaneously, reduced operating efficiency.

Utility model provides a kind of group pincers that rise that prevent the electric cable splitting for fatigue, and this is dialled pincers and mainly comprises dop, locking device, shell, drive rod and handle.Dop is to be fixed together by the retaining mechanism on pull bar by pull bar, and the afterbody of dop is provided with uniform four taper holes of steel ball locking; Locking device comprises lock sleeve, steel ball, back-up ring, spring; Locking device is to be fixed in the enclosure by pull bar by the spring of the back-up ring of pull bar front end and lock sleeve rear end; Handle is to be connected on pull bar and shell by drive rod by spring pivot.

Described dop is a step cylinder, and center is provided with the stepped hole of a bottleneck shape, and front end has groove in circumference 1/4 part, is being provided with a hook-shaped body near groove fore-end, and afterbody is provided with uniform 4 taper holes, and with afterbody groove angle in 90 °.

Described pull bar front end is provided with uniform four taper holes that are connected with dop, and rear end is of a size of a rectangle shoulder frame;

Described shell front end is that a hollow cylinder rear end is a rectangle shoulder frame, and the cylinder of front end is divided into 1/6 symmetrical protruding key.

Described shell, drive rod, handle, pull bar form a planar linkage mechanism by spring pivot, and handle closes up back stay mobile 3mm backward completely.

Described rising dialled pincers and can be solved tape cable connector and in debugging and maintenance process, reduced conventional instrument to extract impulsive force excessive, avoided the problem of the easy fatigue fracture of cable in withdrawal process.
