Embodiment
Embodiment
As Figure 1-3, a kind of Glan cable connector, the Glan cable connector include metal nut 1, internal first core Set 2, long square type sealing ring 3, O-ring seal 4, internal second core retainer plate 5, swivel nut and core retainer plate claw contact portion structure 1-2, nylon Core retainer plate claw 5-1.
Internal first core retainer plate 2 is cased with the metal nut 1, internal second core retainer plate is cased with first core retainer plate of inside 2 5;Locked between the metal nut 1 and internal first core retainer plate 2 by swivel nut and core retainer plate claw contact portion structure 1-2, it is described Increase has gradient on the basis of swivel nut and core retainer plate claw contact portion structure 1-2 stress surface, and the metal nut 1 takes circle Arc transition;It is cased with locking by nylon core retainer plate claw 5-1 between internal second core retainer plate 5 in first core retainer plate of inside 2;The lattice Long square type sealing ring 3 is provided with inside blue cable connector, outside is provided with O-ring seal 4.The Glan cable connector is additionally provided with steel wire 6 are enclosed, tapered trigonometric expression structure is used in design.
Material used in the long square type sealing ring 3 and O-ring seal 4 is silicon rubber.The nylon core retainer plate claw 5-1 materials Matter is low smoke and zero halogen.Second core retainer plate of inside 5 uses nylon material.
Selection method when cable gland head is installed in the present invention is as follows:
One:First have to determine your cable type, if be armored cable, if armored cable line must just use Armored cable stuffing-box.Application method and rules of type selection on armored cable stuffing-box are selected according to relevant criterion.
Two:Use environment requirement, general environment severe local such as ship, chemical plant, petroleum works, natural gas, is examined Consider security and stability, it is proposed that use the more preferable stainless steel of anti-corrosion explosion-proof performance;There is spy to the noisy place of electromagnetic wave Very require, it is proposed that use anti-electromagnetic shielding type cable gland head.
Three:According to the gland head of the type selecting different size of institute's perforate, four kinds of most practical at present thread specifications are public Tooth processed, tooth made in Germany, tooth made in Great Britain, tooth made in U.S.A.Determine that the external diameter of cable is much after screw thread specification is determined, correspond to its joint Contraction scope can.If without perforate, the gland head of different types of thread can be selected according to cable external diameter, According to gland head size and type in its corresponding position perforate.
Four:Particular/special requirement, if desired for reducing gland head, screw thread extended type gland head (equipment thickness of slab is thicker) can be according to reality Border needs to choose different size gland head.
The installation method of cable gland head in the present invention is as follows:
The first step:Measure aperture and the outside diameter of cable selects suitable cable connector.
Second step:The stainless steel cable fixing head end of thread is screwed into equipment, if without screw thread, be through hole, it is necessary to Locking nut is screwed on inside electric equipment, (U.S. standard screw thread NPT is that taper thread is to be unworthy of nut).
3rd step, cable is passed through into lock nut, then passed and fixed by stainless steel cable gland head.
4th step:Locknut is tightened, by cable lock sealing, checks whether cable can move.In use such as Need removal cable, it is only necessary to loosen locknut.
Nylon core retainer plate in the present invention uses halogen-free reinforced nylon, and because conventional nylon fire resistance is bad, water imbibition is led Cause the stability of physical dimension poor, as the important feature of the inside of gland head, to its intensity, heat resistance, cold resistance, fire-retardant etc. Aspect should propose to propose higher requirement.Halogen-free reinforced nylon product excellent fireproof performance, fire-retardant rank reach U94V levels, tool There are low precipitation, anti-drip, high electrical property and excellent heat resistance, CTI values are high, good electric property, and impact strength is high, to environment friend Good, environmental protection, excellent flame retardancy, the processing temperature that this granular nylon can be born is 500F (260 DEG C).Therefore in use this Nylon good stability of the dimension, on the one hand can ensure the close contact and cooperation of cable and gland head, and and can plays good waterproof Effect, another aspect flame retardant effect is excellent, will not produce poisonous and harmful substance.Meet European Union environmental protection ROHS requirements.
Brass in the present invention is used after 600 DEG C × 6h progress units ooze Al and Al, Mn, Fe multicomponent thermochemical treatment, is obtained respectively Alloyed layer that must be about 72 microns and 85 microns, after entering this processing, intensity, wearability, resistance to corrosion etc. have very big Improve.Extend the service life of gland head.
The cable range that the present invention clamps is big, in the design of metal nut and internal first core retainer plate, in increase swivel nut and Increase gradient on the basis of the stress surface of core retainer plate claw contact portion structure, then swivel nut takes arc transition on this basis, Reduce contact torque, increase service life, and cause clamping cable range increase, as in general M25 cable connector clamps electricity Cable scope is 12~18mm, and the M25 clamping cable ranges that the present invention designs are 9~18mm.Each type is expanded in original basis The scope of application of number product, reduce product cost.
The product hermeticity of the present invention can greatly enhance, and improve IP degree of protection.Sealed inside joint using long square type Circle sealing, outside use traditional O-ring seal, inner seal rings internally the second core retainer plate claw section clamp when and cable Restrictive coating is fitted close, and strengthens degree of protection.Material used is low smoke and zero halogen, in burning, will not produce toxic gas, And with certain fire-retardant use.
Chucking power of the present invention is big, and stability is good, and the design product uses double fastener compact form, increases the chucking power of product, carries The stability of high product performance.On the one hand ensure that product is clamped using the convergent force of nylon core retainer plate claw.Another side wire loop Also there is certain chucking power.Tapered trigonometric expression structure is used in design, clamps cable, prevents axial float and the footpath of cable To displacement, greatly improve the stability and service life of product.
The anti-illumination performance of fire resisting of the present invention optimizes significantly, and internal second core retainer plate uses nylon material, and sealing ring uses silicon Rubber, fire resisting and anti-illumination performance are optimized significantly.
Technical scheme in the embodiment of the present invention is clearly and completely described the above, so that the skill of this area Art personnel can be better understood from advantages and features of the invention, so as to make apparent boundary to protection scope of the present invention It is fixed.Embodiment described in the invention is only part of the embodiment of the present invention, rather than whole embodiments, based on the present invention In embodiment, the every other implementation that those of ordinary skill in the art are obtained on the premise of creative work is not made Example, belongs to the scope of protection of the invention.
