Abstract

The utility model discloses a feed-through filtering apparatus with a novel structure and the apparatus comprises two feed-through filters, two outer connection leads and an insulation housing, wherein the outer connection leads are bent 90 DEG. A core-penetrating capacitor and an output lead of the feed-through filter are arranged in the insulation housing. The outer connection leads pass through the insulation housing and are connected with the output leads of the feed-through filters together. The feed-through filtering apparatus provided by the utility model is without adding a commutator when in use, so that assembling links are reduced.

Description

A kind of feedthrough filter

Technical field

The utility model relates to filter and makes field, particularly the feedthrough filter of new construction.

Background technology

In existing technology, small-sized feed-through filter can not directly be connected on client's the equipment under normal conditions, and its reason is that client's closure becomes 90 degree with the direction of the output lead of feed-through filter.Therefore, substantially all need to increase an adapter, just can be connected on the equipment by adapter.

The utility model content

In view of this, the purpose of this utility model is to propose a kind of feedthrough filter of new construction, and it does not need to increase adapter in use again, thereby has reduced the assembling link.

Based on above-mentioned purpose, the utility model provides a kind of feedthrough filter, it comprises feed-through filter, outer connection wire and insulation crust, wherein said outer connection wire bending 90 degree, and the feed-through capacitor of described feed-through filter and output lead are packed in the described insulation crust; Described outer connection wire passes described insulation crust, and links together with the output lead of described feed-through filter.

Alternatively, described outer connection wire is fixedly linked by the output lead of 1 screw and 1 nut and described feed-through filter at least at least, and described nut is embedded on the described insulation crust.

Alternatively, described feedthrough filter also comprises cap, is used for the exposed part of described outer connection wire is protected.

Alternatively, with pack into the junction of output lead of feed-through capacitor in the described insulation crust and described outer connection wire and described feed-through filter of described feed-through filter, use the casting glue embedding.

Further, described casting glue is epoxy resin or silica gel.

What alternatively, described insulation crust used is the polybutylene terephthalate (PBT) material.

Can find out that from above the utility model provides the feedthrough filter of new construction, it connects wire at home and abroad and passes insulation crust, and links together with the output lead of feed-through filter respectively.Thereby, only need to be connected to equipment on the input and output wire of feedthrough filter of described new construction in use, reduced the operation that connects the another one adapter, improved simultaneously the reliability of device, saved the device space.

Embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, the utility model is further described.

With reference to shown in Figure 1, assembling schematic diagram according to the feedthrough filter of an embodiment of the utility model is shown, described feedthrough filter comprises feed-through filter 1, outer connection wire 3 and insulation crust 2, it connects wire 3 bendings 90 degree at home and abroad, and the feed-through capacitor of feed-through filter 1 and output lead are packed in the insulation crust 2; Outer connection wire 3 passes insulation crust 2, and links together with the output of feed-through filter 1 respectively.Wherein, the connection of the output that insulation crust 2 external connection wires 3 are connected with feed-through filter can be played positioning action, can also insulate simultaneously.

In an embodiment of the present utility model, 2 feed-through filters 1 are installed together side by side, in the insulation crust 2 of simultaneously feed-through capacitor of 2 feed-through filters 1 and output lead being packed into.Preferably, outer connection wire 3 can be copper conductor.

With reference to Fig. 2, the structural representation according to the feedthrough filter of another embodiment of the utility model is shown, in an embodiment of the present utility model, described feedthrough filter also comprises cap 6, is used for the external exposed part that connects wire 3 and protects.What preferably, insulation crust 2 adopted is polybutylene terephthalate (PBT) (PBT) material.

With reference to Fig. 2, profile according to the feedthrough filter of another embodiment of the utility model is shown, in an embodiment of the present utility model, outer connection wire 3 is fixedly linked by at least 1

screw

5 and 1 nut 4 output lead with feed-through filter 1 at least, nut 4 is embedded on the insulation crust 2, thereby makes its connection more reliable.Preferably, outer connection wire 3 uses 2

screws

5 and 2 nuts 4 and the output lead of feed-through filter 1 to be fixedly linked.Wherein, feed-through filter 1 can also be packed into the feed-through capacitor in the insulation crust 2 and the output junction that connects wire 3 and feed-through filter 1 outward; use the casting glue embedding, play the effect of the feed-through capacitor of the protection wire of fixed connection place and feed-through filter 1.Preferably, described casting glue is epoxy resin or silica gel.

It is pointed out that outer connection wire 3 as the wire of the output of whole feedthrough filter, also can be fixed with screw.Turn on screw during use, the wire of output terminal of equipment wire and described feedthrough filter is fitted, again screw-driving.

Wherein, for the internal structure of the feedthrough filter that can see described new construction clearly, Fig. 1, Fig. 2 and Fig. 3 have removed the insulation crust of a upper surface part.

Can find out that from top description the feedthrough filter of new construction described in the utility model forms as one feed-through filter with the outer wire that is connected, do not need to increase in addition adapter again, has reduced the assembling link; The feed-through filter wire of output terminal is fixed with screw-nut with outer connection wire, makes connection more reliable; And with feed-through filter pack in the insulation crust feed-through capacitor and connect wire outward and the junction of feed-through filter output, use the casting glue embedding, can protect wire and the feed-through capacitor of fixed connection place; In addition, the feedthrough filter of described new construction comprises insulation crust, has played the effect of location and insulation; Arranging of cap has good protective effect to exposed outer connection wire; Simultaneously, the feedthrough filter of new construction described in the utility model can greatly reduce cost and reduce installing space.

Those of ordinary skill in the field are to be understood that: the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle; any modification of making, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
