Abstract

Disclosed is a high-temperature connector, which is a line connector, comprising a casing, a contact ring and a connecting lead, which is characterized in that the casing comprises two separable jackets and ferrules sheathed on the jackets; the two separable jackets are made of fireproofing materials and embedded with the contact ring and the connecting lead; the external connecting lead is sheathed with a thin sleeve tube made of fireproofing materials. One end of the casing is the plug patch hole, the other end passes through the connecting lead. The connector is available at high temperatures of over 400 DEG until below the fusing point of the metal materials of the components, and the structure is convenient to repair and the components can be easily exchanged. The utility model has the advantages of long service life, low cost and common primary materials.

Description

High-temp. connector

The utility model relates to a kind of connector of circuit, is specifically related to a kind of connector of high temperature resistance.

Connector is a kind of line connector, for example in pair rifle temperature measuring equipment of steel mill, it is a kind of critical component, supporting connection combined probe, to pop one's head in and insert in the molten steel, can measure liquid steel temperature, phosphorus content and oxygen content etc.,, connector can be installed on the artificial temperature-measuring gun not possessing the steel mill of paying the rifle thermometric, connect probe again, the connecting line of temperature-measuring gun is connected with relevant instrument, can reach artificial thermometric purpose, and its effect is the same with pair gun apparatus.

Along with the development of melting technique, iron and steel cause, the high temperature test device also is more and more widely used.In existing connector, the connector of Japanese manufacturing is to adopt rubber and resistant to elevated temperatures plastic sheath lead monolithic devices to cast as shown in Figure 1, and it comprises: the rubber sleeve 1 of monolithic devices, contact ring 2, end contact ring 3, compensating wire 4.Contact ring 2 and end contact ring 3 are to embed in the inboard wall groove of overcoat 1, compensating wire 4 is corresponding respectively to be connected with

contact ring

2,3, constitute an end like this and be connected to the pass instrument by compensating wire 4, the other end has jack, this hole extends to inner hole through each contact ring with end contact ring 3 as introducing jack always, and this jack is to insert and be provided with for the plug of accepting to pop one's head in.Be with resistant to elevated temperatures plastic sheath outside the compensating wire 4, this plastic sheath can resist and is lower than 400 ℃ high temperature, meet the short good insulation preformance that do not melt of naked light time, but also existing following defective (1) in actual use meets flue gas, steam and dirt and can infiltrate in the extension bar spare, can cause insulation resistance to descend like this, because its overcoat is a monolithic devices, the dirt that infiltrates in the connector can't clean up, the insulation property difference or the part parts damages have to scrap the connector that needs transposing new; (2) serviceability temperature can not be too high, just might burn out if be higher than 400 ℃.Owing to above reason causes connector short useful life, change frequently, generally use 20 times, only can use once sometimes.Especially connector burns out during pneumatic steelmaking, can not maybe will survey composition by the correct measurement liquid steel temperature, will influence steel quality, and the loss that causes like this is very big.

In order to overcome above defective, a purpose of the present utility model is the connector that a kind of high temperature resistance will be provided, and the environment for use temperature can surpass more than 400 ℃ even reach that this connector still can not burn out about 700 ℃.

Another purpose is that a kind of connector with overcoat of separate type will be provided, and is convenient to maintain and change inner parts.

Therefore, connector provided by the utility model, mainly comprise overcoat, contact ring and be connected lead, contact ring is to embed in the inboard wall groove of overcoat, connecting lead is connected with corresponding contact ring respectively, one end of overcoat is the patchhole of plug, the other end is by connecting lead, it is characterized in that above-mentioned overcoat comprises two separable chucks and the ferrule that is enclosed within their outsides, these two separable chucks are made by refractory material, and above-mentioned connection lead is with the thin sleeve pipe that refractory material is made outward.

Because the overcoat of connector of the present utility model is that refractory material is made, and inner connection lead is with the thin sleeve pipe that refractory material is made outward, thus it can use more than 400 ℃ in connector under the high-temperature condition below the metal material fusing point of parts.In addition because of overcoat be two can divide at chuck, compare favourable maintenance and transposing parts with monolithic devices.Its chuck shape can change circular arc preferably.Above refractory material can be selected as aluminium oxide silica, silicon nitride ceramic material or their mixture etc. for use.These materials are general, wide material sources.Wherein proper with aluminium oxide.So this connector is easy to manufacture, cost is low.

Further specify the utility model below in conjunction with the embodiment accompanying drawing.

With reference to figure 2, connector provided by the utility model comprises contact ring 2, and end contact ring 3 connects lead 4, and chuck spare 5,6 tightens up cuff 7 down, plunger 8 and on tighten up cuff 9.Contact ring the 2, the 3rd, ring-type contact connection so that the plug of probe inserts, they can be that the higher metal material of the high fusing point of conductance is made, and generally adopt copper and copper alloy to make, in order to improve its electric conductivity, its surface also can be silver-plated.End contact ring 3 contacts connection in the end of connector patchhole, and the plug that also can be used as probe is introduced and guide effect.These contact rings all are to embed in the groove of Hough chuck spare 5,6 outer casing inner walls that constituted, and each contact ring all is connected with the corresponding lead 4 that is connected.Hough chuck spare 5,6, constitute that the plug insertion end at probe is with ferrule 9 outside the overcoat, this ferrule 9 insert mouthfuls 10 have in crimping so that push down Hough chuck spare 5,6; Other end outside at this overcoat is with ferrule 7, ferrule 7.9 generally is copper or copper alloy, connect lead 4 at connector and be plugged with plunger 8 by the overcoat inside of holding, connecting lead 4 passes from plunger 8 holes, the relative position of the fixedly connected lead 4 of these plunger 8 energy, also can support and reinforcing clip

external member

5,6 simultaneously.This plunger 8 can be organic silicon rubber material and makes, and it also plays cushioning effect in connector.

Referring to Fig. 3-8, as seen chuck spare 5, the 6th, Hough shape one side respectively is provided with long and narrow stairstepping breach, so that on the connection lead 4 that connects

contact ring

2,3, be inserted in the thin sleeve pipe that refractory material is made, Hough chuck spare 5, has the groove that adapts with

contact ring

2,3 sizes on 6 inwalls so that

contact ring

2,3 embeds wherein, so structure maintenance for convenience and change parts.
