Description

The A.C. contactor that a kind of static iron core is assembled using spring clip and rubber blanket

Technical field

A.C. contactor technical field is the utility model is related to, a kind of static iron core is related specifically to and uses spring clip and rubber Pad the A.C. contactor of assembling.

Background technology

Contactor is a kind of to be used to be frequently switched at a distance and disconnect alternating current-direct current main circuit and Large Copacity control circuit Electrical equipment.Its major control object is motor, it can also be used to controls other electrical loads such as electric heater, illuminating lamp, electric welding mechanical, electrical Container group etc..

Contactor is in attracting process, electromagnetic attraction caused by coil, dynamic iron core is produced relative motion with static iron core, existing There is technology coil to be wrapped on static iron core, bottom and the static iron core of coil are adjacent to, for limiting static iron core in electromagnetic attraction Follow dynamic iron core to move upwards under effect, easily produced with static iron core by the bottom of the coil of the A.C. contactor used for a long time Raw gap, the dynamic iron core of the A.C. contactor adopted the structure is with static iron core in relative movement, and static iron core is in electromagnetism Easily dynamic iron core is followed to move upwards in the presence of suction, so that static iron core produces larger impact to coil, impact is serious Meeting cause coil to damage, so as to occur contactor product function failure, be not only difficult to make contactor normal work, and also drop The low service life of contactor.

But in view of the shortcomings of the prior art, developer is necessary that development one kind is reasonable in design, simple in construction, can avoided Coil is impacted by static iron core, is not only able to make contactor normal work, and can also effectively improve making for contactor The A.C. contactor assembled with the static iron core in life-span using spring clip and rubber blanket.

Utility model content

To solve the problems, such as that prior art is present, the utility model purpose provides a kind of reasonable in design, simple in construction, energy Enough avoid coil from being impacted by static iron core, be not only able to make contactor normal work, and can also effectively improve contact The A.C. contactor that the static iron core of the service life of device is assembled using spring clip and rubber blanket.

To solve above technical problem, the utility model is realized using following technical scheme：

The A.C. contactor that a kind of static iron core is assembled using spring clip and rubber blanket, including lower house, upper shell, dynamic iron core And static iron core, the upper shell are arranged on the top of lower house, the dynamic iron core is removably set on upper shell, and its feature exists In the A.C. contactor also includes being used for the spring clip being arranged on static iron core on lower house, on the both ends of the spring clip Felt pad is inserted with respectively, is located in the middle part of the spring clip on static iron core, coil is wound with the static iron core, is set It is crimped in the convex closure of the coil bottom on felt pad, makes to form a cushion space between the convex closure and static iron core.

In a preferred embodiment of the present utility model, the felt pad is rubber blanket.

Compared with prior art, the utility model also includes being used for the spring clip being arranged on static iron core on lower house, Felt pad is inserted with the both ends of spring clip respectively, is located in the middle part of spring clip on static iron core, is wound on static iron core wired Circle, the convex closure for being arranged on coil bottom are crimped on felt pad, make to form a cushion space between convex closure and static iron core, using this Kind structure can avoid coil from being impacted by static iron core, be not only able to make contactor normal work, and can also be effective Improve the service life of contactor.

Brief description of the drawings

, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work Under, other accompanying drawings can also be obtained according to these accompanying drawings.

Fig. 1 is one of structural representation of the present utility model.

Fig. 2 is the two of structural representation of the present utility model.

Embodiment

In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under Face combines and is specifically illustrating, and the utility model is expanded on further.

Ac contactor shown referring to Figures 1 and 2, that a kind of static iron core provided in figure is assembled using spring clip and rubber blanket Device, including lower house, upper shell, dynamic iron core 100 and static iron core 200.

Upper shell is mounted by means of bolts on the top of lower house, and upper shell forms the space of a closing with lower house, Dynamic iron core 100 is removably set on upper shell, and dynamic iron core 100 can move down and quiet iron in the electromagnetic attraction of coil 400 Core 200 contacts.

The A.C. contactor also includes being used for the spring clip 300 being arranged on static iron core on lower house, in spring clip 300 Felt pad 500 is inserted with both ends respectively, the middle part of spring clip 300 is located on static iron core 200, wound on static iron core 200 Have coil 400, the convex closure 410 for being arranged on the bottom of coil 400 is crimped on felt pad 500, make convex closure 410 and static iron core 200 it Between form a cushion space 600.

Cushion space 600 can avoid impact of the coil 400 by static iron core 200, effectively raise A.C. contactor Service life.

Felt pad 500 is rubber blanket, and the felt pad 500 being fabricated using rubber not only increases the felt pad 500 Insulating properties, and also improve the shock-absorbing capacity of felt pad 500.

The utility model also includes being used for the spring clip being arranged on static iron core on lower house in summary, in spring clip Felt pad is inserted with both ends respectively, is located in the middle part of spring clip on static iron core, coil is wound with static iron core, be arranged on The convex closure of coil bottom is crimped on felt pad, is made to form a cushion space between convex closure and static iron core, is adopted the structure energy Enough avoid coil from being impacted by static iron core, be not only able to make contactor normal work, and can also effectively improve contact The service life of device.

The advantages of general principle of the present utility model, principal character and the utility model has been shown and described above.One's own profession The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification Simply illustrate principle of the present utility model, the utility model can also on the premise of the spirit and scope of the utility model is not departed from There are various changes and modifications, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model will Protection domain is asked to be defined by appended claims and its equivalent.
