Abstract

The present invention discloses a novel plier for preventing a cable from a fatigue break. The plier mainly includes a clip head, a locking device, a housing, a driving rod and a handle; the clip head is fixed to a pulling rod through locking mechanism on the pulling rod; the locking device includes a locking sleeve, a steel ball, a retainer ring, and a spring; the locking device is fixed in the housing by a retainer ring of a pulling rod front end and the spring of a locking sleeve rear end through the pulling rod; the handle is connected to the pulling rod and the housing by an elastic pin through the driving rod; the housing front end is a hollow cylinder body, the rear end is a rectangle shoulder frame, a front end of the cylinder body is divided into 1/6 raised keys which are evenly distributed; during operations, the handles on two sides are folded, driving the driving rod to bring the pulling rod to move backwards along an axis of the housing, so that a pull-out operation with limited height is performed on a connected having a cable; and the plier can solve the problems, i.e., achieving reducing an oversize impact force caused by a conventional tool during pulling out in the process of adjusting and maintaining the connector having the cable, and avoiding the fatigue break of the cable during pulling out.

Description

A kind of novel group of pincers preventing the electric cable splitting for fatigue

Technical field

The present invention relates to a kind of nipper, be specifically related to a kind of novel group of pincers preventing the electric cable splitting for fatigue.

Background technology

In the radio circuit of wireless device and electronic instrument, coaxial cable is fixed often through two terminal adapters.Two terminal adapters are co-axial cable components that a kind of curved formula pushes stopping type, are made up of the connector at two ends and a coaxial cable of centre.Two terminal adapters be curved formula push stopping type co-axial cable component in the middle of connect the cable assembly of comparatively hard (rigidity) cable, have that volume is little, lightweight, reliability high, be 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 is the method such as stick up thick stick separate type, step bayonet type, tweezers clamping are extracted, and first pulls out a terminal adapter of cable assembly, is then pulling out other one end.Owing to pulling out time of releasing impulsive force, the bad control of impact distance of connector in place's process, comparatively hard or that flexibility is bad cable is often easily occurred excessive pulling cable, thus causes the problem of distortion of the cable or fracture.If two terminal adapters are than on the integrated plate of comparatively dense, adopt hand or common pliers to carry out plugging very inconvenient, more easily cause cable bend and rupture.In continuous swapping process, cause cable bend increased frequency in addition, cause the root fatigue fracture of cable, will the electrical property of cable assembly be affected, to such an extent as to cable assembly is scrapped, add production cost, make troubles to debugging and maintenance work simultaneously, reduce operating efficiency.

Summary of the invention

In order to avoid the deficiencies in the prior art part, the present invention proposes a kind of novel group of pincers preventing the electric cable splitting for fatigue, tape cable connector can be solved in debugging and maintenance process, extract difficulty, and for the problem connecting the frequent easily fatigue fracture of harder cable root in swapping process.

Invention provides a kind of and prevents novel of the electric cable splitting for fatigue to dial pincers, and this plays nipper and mainly comprises dop, locking device, shell, drive rod and handle.Dop is 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 fixing 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 connected on pull bar and shell by drive rod by spring pivot.

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

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

Described case nose is a hollow cylinder rear end is a rectangle shoulder frame, and the cylinder of front end is divided into 1/6 symmetrical convex key.

The described nipper that rises can solve tape cable connector and in debugging and maintenance process, decreases conventional tool to extract impulsive force excessive, avoids the problem of the easy fatigue fracture of cable in withdrawal process.
