Abstract
Contactor with modified form pedestal.The pedestal for mainly solving existing contactor tends to full closeding state, is unfavorable for radiating, and can increase product Wen Sheng, influences product service life problem.It is characterized in that：The pedestal（1）Bottom outer wall is equipped with the through-hole being connected to the holding tank（11）.The utility model provides the contactor with modified form pedestal, Foundation Plate of Contactor inside through-hole with outside by communicating, when contactor arc burning, contactor extraneous air can be entered chassis interior by these through-holes and be compensated to inner air, weaken internal gas flow, reduces electric arc and introduce the trend of solenoid chamber and then reduce product phase fault phenomenon；In addition, through-hole helps to reduce product Wen Sheng, promotes product electric life and then improve product quality.
Description
Technical field
The utility model is related to contactor fields, specially the contactor with modified form pedestal.
Background technology
Contactor be widely used as electric power cut-off and control circuit.It is opened and closed circuit using contact, generally comprise including
Four parts：1, electromagnetic system, including sucking coil, dynamic iron core and static iron core；2, contact system, including three groups of main contacts and one
To two groups of normally opened, normally closed auxiliary contacts, it and dynamic iron core are the mutual linkages that connects together；3, arc-control device, general capacity are larger
A.C. contactor be designed with arc-control device, a quick breaking arc, in order to avoid burn out main contact；4, insulation crust and attachment,
Various springs, transmission mechanism, short-circuited conducting sleeve, binding post etc..
Existing contactor would generally be covered using dust-proof note, and pedestal tends to full closeding state, when contactor connect with
Since the burning of electric arc will produce air flowing when disjunction, it is unfavorable for dissipating since Foundation Plate of Contactor is in full closeding state
Heat can increase product Wen Sheng, influence product service life.
Utility model content
In order to overcome the shortcomings of that background technology, the utility model provide the contactor with modified form pedestal, mainly solve
The pedestal of existing contactor tends to full closeding state, is unfavorable for radiating, can increase product Wen Sheng, influences product service life and ask
Topic.
Technical solution used by the utility model is：
Contactor with modified form pedestal, including pedestal, the interior holding tank being equipped with for installing bobbin of the pedestal,
The base bottom outer wall is equipped with the through-hole being connected to the holding tank.
The utility model has the beneficial effects that：The utility model provides the contactor with modified form pedestal, contactor bottom
Seat inside through-hole with outside by communicating, and when contactor arc burning, contactor extraneous air can be entered by these through-holes
Chassis interior simultaneously compensates inner air, weakens internal gas flow, reduces electric arc and introduces the trend of solenoid chamber and then reduce production
Short circuit phenomenon between condition；In addition, through-hole helps to reduce product Wen Sheng, promotes product electric life and then improve product quality.

Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings：As shown, the contactor with modified form pedestal,
Be equipped with the holding tank 3 for installing bobbin 2 including pedestal 1, in the pedestal, 1 bottom outer wall of the pedestal be equipped with it is described
The through-hole 11 of holding tank connection.Foundation Plate of Contactor inside through-hole with outside by communicating, when contactor arc burning, contactor
Extraneous air can be entered chassis interior by these through-holes and be compensated to inner air, and internal gas flow is weakened, and reduce electric arc
It introduces the trend of solenoid chamber and then reduces product phase fault phenomenon；In addition, through-hole helps to reduce product Wen Sheng, product is promoted
Electric life improves product quality in turn
In the present embodiment, as shown, the base side wall is equipped with the straight slot being connected to the holding tank.Further plus
Strong heat dissipation effect.
In the present embodiment, as shown, the cross section of the straight slot be L-shaped, and the straight slot include translot 121 and to
The vertical slots 122 of upper extension, the translot are set on the base side wall, and the relatively described translot of the base inner wall is equipped with wind-guiding
Seat 13, the vertical slots are set in the air guiding seat, and the translot 121 in the vertical slots and the pedestal 1 by being connected to.It can
It reduces dust clast etc. and enters interiors of products, improve the dirt exclusion capabilities of product, if there is dust can quilt in the air entered in translot
It leads a point seat to stop, air enters with vertical slots in pedestal after rising, and as that can select one of scheme, can also set in vertical slots
Set strainer.
In the present embodiment, as shown, the air guiding seat be equipped with buckle 132, the buckle be used for in pedestal 20
Wall is engaged by clamping.Installation is more easy.
In the present embodiment, as shown, the translot is the horn-like structure of big opening outwardly.
In the present embodiment, as shown, the through-hole is kidney slot.
In the present embodiment, as shown, the base side wall is equipped with several platforms 14, the bobbin 2 includes bottom
Plate 21, the bottom plate are equipped with boss 22, and the boss 22 is equipped with wrapping post 23, and the bottom plate 21 is set to the platform upper end
Face, the wrapping post are set in the holding tank.
In the present embodiment, as shown, the platform includes 141 He of the first platform before and after being correspondingly arranged at the boss
