Description

Contactor coil

Technical field

The utility model relates to the accessory technical field of contactor, specifically refers to a kind of contactor coil.

Background technology

Contactor broadly refers to utilize in the industrial electro control techniques coil current flowing to produce magnetic field, makes contact closure, to reach the electrical equipment of control load.Contactor is comprised of electromagnetic system (unshakable in one's determination, solenoid) contact system (normally open contact and normally closed interlock) and arc-control device.It is widely used in the control field of electric equipment.Coil wherein is an important accessory of contactor.In prior art, contactor coil adopts the structure as shown in accompanying drawing 1 and accompanying drawing 2 mostly, it comprises skeleton 01 and the enamelled wire 02 that is wrapped on skeleton 01, described enamelled wire 02 is much as the situation in accompanying drawing 1, directly outside exposed, what have is surrounded by one deck insulating tape on outermost enamelled wire 02.03, the end of a thread of described enamelled wire 02 is directly to wrap from the line that is wound around lopping to draw.The contactor coil of said structure has the following disadvantages: 1, enamelled wire 02 lacks effectively protection, and when contactor was operated in vibrations by force or bumps with other metalwork, enamelled wire 02 breakage easily occured causes that coil opens circuit or short circuit.2, enamelled wire 02 is directly exposed or only be wound around through simple insulating tape, and water resistance is poor, and in wet environment lower time, enamelled wire 02 easily leaks electricity when the contactor long-term work.3, coil is when work, and effectively isolation, noise easily do not occur afterwards in energising.4, the bad control of safe distance between the line bag out-of-shape that is wound around out due to enamelled wire 02 when mounted of coil, itself and other element makes other element of periphery will keep with it larger spacing, and limitation is arranged on space layout.

The utility model content

The technical problems to be solved in the utility model is, provide a kind of can waterproof, shockproof, operating noise is little, is not easy electric leakage, uses the little contactor coil of time space layout limitation.

For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of contactor coil, and it comprises at least one coiling unit, and described coiling unit comprises skeleton and enamelled wire, and described enamelled wire is wrapped on skeleton; Described enamelled wire is coated with the insulating barrier that one deck seals up enamelled wire outward, is equipped with the wiring construction that stretches out in outside insulating barrier on initial the end of a thread of described enamelled wire and end the end of a thread.

After adopting above structure, the utlity model has following advantage: 1, enamelled wire is coated with the insulating barrier that one deck seals up enamelled wire outward, when contactor was operated in vibrations by force or bumps with other metalwork, enamelled wire was not easy to occur damaged, can not cause that coil opens circuit or short circuit.2, enamelled wire has been sealed, and water resistance is good, and in wet environment lower time, enamelled wire is not easy electric leakage when the contactor long-term work.3, contactor coil is in when work, and insulating barrier plays good buffer action, sends noise because of operational vibration and is insulated layer and has well shielded.Although 4 contactor coils are the line bag out-of-shape that is wound around out of enamelled wire when mounted, but the filling effect by insulating barrier can become the sharp processing of contactor coil the regular shape of Design of Dies, safe distance between contactor coil and other element just can well be controlled like this, make the periphery other element distance with it can be less, the limitation on space layout is less.

As preferably, the thickness of described insulating barrier is not less than 0.7mm.This thickness range can guarantee that contactor coil has good insulation property and waterproof, the performance such as shockproof.

As further preferred, the thickness of described insulating barrier is 1mm.This one-tenth-value thickness 1/10 can be so that the performance of contactor coil and cost obtain best balance.

As preferably, described insulating barrier is integrally formed through die casting by poly-terephthaldehyde's second two fat insulating material.The advantages such as poly-terephthaldehyde's second two fat insulating material have lightweight, and powerful height and gas barrier properties are good, and be nontoxic, tasteless.

As preferably, described insulating barrier covers covered framework simultaneously, but on skeleton with the frame center hole be uncovered.Skeleton is together covered, make the plasticity of whole product stronger.

As improvement, described wiring construction refers to binding post, and described binding post comprises the first binding post and the second binding post, and an end of the first binding post is connected with initial the end of a thread of enamelled wire and is sealed in insulating barrier with first of start line; The other end of the first binding post stretch out in outside insulating barrier and above be provided with the first screwed hole for wiring; One end of the second binding post is connected with end the end of a thread of enamelled wire and is sealed in insulating barrier with first of end lines; The other end of the second binding post stretch out in outside insulating barrier and above be provided with the second screwed hole for wiring.Binding post be arranged so that wiring is more convenient.

Further improve, also be respectively equipped with on described the first binding post and the second binding post and the first screwed hole and supporting pad and the screw of the second screwed hole.This structure has further been optimized the wiring convenience of binding post, and the user is by being wound in line on screw, then compresses with pad and just line can be connected, and saved welding step, and dismoutability is better.

As improvement, described insulating barrier is hexahedron structure, and coiling unit is positioned at hexahedral centre, and two corners of described hexahedron one end are the arc corner; Two corners of the described hexahedron other end are extended with respectively for the first projection and the second projection that binding post is installed.This structure makes the contactor coil monnolithic case more level and smooth, and corner angle still less are not easy to bump to other parts.
