Description

Switchgear power contact and power contact insulation division

Present invention preamble according to claim 1 is related to a kind of with power contact insulation division (Leistungskontaktisolierung) for switchgear (Schaltanlage, otherwise referred to as power distribution equipment), The especially switchgear power contact (Schaltanlagenleistungskontakt) of low voltage switch equipment.

In known contact system, in all cases using contact element (Kontaktelement, otherwise referred to as Contact element), it is placed in copper or brass element.Electric current flowing mainly realizes on the contact members, but may can also be by Corresponding contact pin (Kontaktpin, otherwise referred to as contact plug) is directly delivered to socket, and (Buchse is otherwise referred to as inserted Seat) on body, more precisely there is no problem in the situation of rated current for this.

It can be disadvantageously, in the case where short circuit however to generate relatively high electric current stream in the situation of such arrangement It is dynamic, it can equally cause the dynamic motion for contacting pin or corresponding contact socket accordingly.The movement can lead to, and can produce Electrical contact between pin and socket outside contact element.Because electric current is highly fallen relatively in short-circuit conditions, this may Lead to the mechanically and electrically damage for more specifically pin and socket, this can negatively affect again and change its contact row For.

In order to overcome shortcomings noted above, the present invention proposes following task, illustrates a kind of improvement for switching devices Power contact element, wherein in the case where short circuit, as much as possible avoid contact with pin or contact socket machinery and/ Or electrical damage.

The task is by a kind of feature with claim 1 for switchgear, the function of especially low voltage switch equipment Rate contact solves.Advantageous design scheme and improvement plan and power contact insulation division of the invention and at least one this The switchgear of the power contact of sample, especially low voltage switch equipment illustrate in other claim and in subsequent description.

Correspondingly, switchgear power contact according to the present invention has in contact receptacle interior and/or is connecing in outside At least one insulating layer in the form of at least one electrical insulation parts on pin is touched, in contact pin and contacts socket It is prevented in the case where relative motion as follows, that is, electric current is in the contact element flows outside being arranged thus and is restricted to contact element On electric current flowing.

Thus equally guarantee in the case where dynamic motion as follows, that is, electric current only flows on the contact members and prevention pair In the damage of pin or socket.

In advantageous design scheme, insulation division and/or insulation component herein can ring type and/or cup type implement.Change It can be set into ground, be brought on the side of pin or socket or on the side of pin and socket.

Advantageously, the fastening of at least one insulation component can pass through or by means of most different fixed forms, it is such as especially viscous It connects, compress, clamping lock and similar promoting.

With improvement, shape cooperation and/or force-fitting connection can be promoted herein.

Advantageously, can be set to herein, insulation component not only meets insulation function, but also undertake by contact spring keep or Fasten function in place.

Furthermore advantageously, insulation component so constructs, so that it is same mechanical other than insulation function or insulating effect Ground supports contact spring in the situation of pin or the dynamic motion for contacting pin, especially in the situation of the short circuit of appearance, and/ Or make pin or contact pin centering in socket or contact socket.

It is advantageously arranged to, corresponding insulation component conducts that the material of the function of current, such as example polyimides is thin by not Membrane material (Kapton), or by dielectric, such as such as paint or insulated paint or laminate to conduct the function of current not (Laminierung, otherwise referred to as overlay film) coating is applied the material covered and is formed, wherein apply cover and/or coating especially complete cycle to Ground and/or comprehensively or by entire surface and/or on entire contact surface promote.

Equally can be set to, insulant by means of the main body of partial interruption, for example by means of locking nub (Noppen) or sealing (Schlitzung) promote, from the insulating layer without forcibly structural closure.

Advantageously as dielectric, it may be provided with not only formed by the plastics in the form of solid or film herein Medium and with medium existing for liquid form first such as paint or laminate and analog.

It advantageously can be set to herein, at least one insulation component is formed by polyimide film material.

Furthermore a kind of power contact insulation of power contact for switchgear, especially low voltage switch equipment is claimed Portion, have by side surround contact element in a manner of contact socket in and/or contact pin on at least one At least one insulating layer of the form of electrical insulation parts, and prevented in the case where contacting pin and contacting the relative motion of socket It is as follows, that is, electric current is in the contact element flows outside being arranged thus and is restricted to the electric current flowing on contact element.

Advantageously, it can be set to, there are two the insulation components that contact element is surrounded in side for setting, wherein one is exhausted especially The cup type ground of edge element or it is telescopic construct and insulation component ring type construct.

It can be set to, be brought on the side of pin or socket or on the side of pin and socket with improvement.

Advantageously, the fastening of corresponding insulation component can pass through or by means of most different fixed forms, such as especially bonding, It compresses, clamping lock and similar promote.

With improvement, shape cooperation and/or force-fitting connection can be promoted herein.

Advantageously can be set to herein, insulation component not only meets insulation function, but also undertake by contact spring keep and Fasten function in place.

It advantageously can be set to, corresponding insulation component conducts the material of the function of current, such as such as polyimides by not Thin-film material, or by being covered with conducting the dielectric of the function of current, such as such as paint or insulated paint or laminate coating not or applying Material formed, covered and/or coating is especially complete circumferentially and/or comprehensively or by entire surface and/or in entire contact surface wherein applying On promote.

Equally can be set to, insulant promotes by means of the main body of partial interruption, for example by means of locking nub or sealing, from Without force that the insulating layer of ground structural closure.

Advantageously as dielectric, it may be provided with not only formed by the plastics in the form of solid or film herein Medium or main body and with medium existing for liquid form first such as paint or laminate and analog.

Advantageously, it is arranged to herein, at least one insulation component is formed by polyimide film material.

The present invention and the other explanation for being advantageously improved scheme and design scheme are carried out according to figure and embodiment.

Unique figure shows in cross section the contact socket 1 of switchgear power contact, with arranging in socket 2 , rise conduction the function of current contact element 3 and ring type open end receptacle interior circumferentially and adjacent to The insulation component 4 of contact element arrangement, conducted by not the function of current material such as such as polyimide film material or by with It does not play the dielectric such as such as paint or insulated paint or laminate coating of the conduction function of current or applies the material covered and constitute, wherein applying It covers and/or coating especially circumferentially and/or comprehensively or by entire surface or on the described and/or described entire contact surface is promoted entirely Make.In addition, be configured near the socket bottom adjacent to contact element 3 it is another, be specifically formed from an electrically-insulative material cup typely Insulation component 5.Alternatively in cup type embodiment, the embodiment that ring type can also be selected herein.
