Description
Technical field
The utility model relates to thermal resistance, more particularly, relates to a kind of quick connection thermal resistance.
Background technology
In industrial large-sized equipment, in the thrust bearing oil sump as the hydraulic turbine, consider the reliability of thermal resistance at present, what generally select for use is the thermal resistance that the band lead extends.This thermal resistance mainly is made up of temperature element, protection tube, set bolt and thermal resistance lead-in wire.This thermal resistance environment of living in is more abominable, and the lead-in wire that will prolong after thermal resistance installs on temperature measuring equipment is arranged in the rugged environment, and long prolongation lead-in wire is transferred to temperature measurement signal in the demonstration and control device of rear end by narrow space.If the thermal resistance probe damages, environment of living in is abominable, installing space is narrow and small because thermal resistance goes between, and causes thermal resistance to change difficulty, and, the wiring of rear end can only be changed together during replacing.Maintenance to field apparatus causes very big difficulty like this.
The utility model content
The technical problems to be solved in the utility model is, at the above-mentioned defective of prior art, need not to remove the quick connection thermal resistance of rear end wiring when a kind of the replacing is provided.
The technical scheme that its technical matters that solves the utility model adopts is: propose a kind of quick connection thermal resistance; comprise set bolt, protection tube and the temperature element that is encapsulated in described protection tube head; described thermal resistance also comprises the connector plug and the connector body of mutual grafting; described connector plug is anchored on being connected away from protection tube one end and with the lead-in wire of described temperature element of described set bolt, and described connector body is connected with the thermal resistance lead and draws described lead along the second direction vertical with the grafting direction.
Among the embodiment according to quick connection thermal resistance of the present utility model, described connector plug is provided with a plurality of contact pins that are connected with the temperature element lead-in wire, and described connector body is provided with a plurality of jacks that match with described a plurality of contact pins.
Among the embodiment according to quick connection thermal resistance of the present utility model, described connector plug is fastened in the described set bolt by gland nut.
Among the embodiment according to quick connection thermal resistance of the present utility model, described thermal resistance also comprises the locking screw ring with connector plug and connector body locking.
Among the embodiment according to quick connection thermal resistance of the present utility model, the wire terminals of described connector body is provided with cable jacket.
Among the embodiment according to quick connection thermal resistance of the present utility model, described cable jacket is the metallic cable chuck, has cable and compresses O-ring seal.
Quick connection thermal resistance of the present utility model adopts bent angle type quick coupler to realize that the thermal resistance probe segment is connected with the fast insert-pull of extension lead.If the thermal resistance probe damages, can under the situation of not removing thermal resistance rear end wiring route, in time change thermal resistance, thereby shorten the working time of changing thermal resistance when main equipment overhauls, save the human and material resources cost in the plant maintenance process.
The bent angle type quick coupler that quick connection thermal resistance of the present utility model adopts can be designed to the international standard attachment unit interface, realize the interchangeability of thermal resistance, homostructural thermal resistance is accomplished standardized production owing to can realize the interworking exchange, reduce cost of products, increase work efficiency.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation according to the thermal resistance of an embodiment of the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, mainly form according to the quick connection thermal resistance 10 of an embodiment of the utility model by cable jacket 11, connector body 12, locking screw ring 13, connector plug 14, gland nut 15, set bolt 16, protection tube 17 and the temperature element (not shown) that is encapsulated in these protection tube 17 heads.Wherein, set bolt 16, protection tube 17 and temperature element constitute the probe segment of this thermal resistance, and cable jacket 11, connector body 12, locking screw ring 13, connector plug 14 and gland nut 15 match and constitute the bent angle type quick coupler part of this thermal resistance.This thermal resistance cooperates the reliable electrical connection that realizes between probe segment and the external wire by the quick grafting between connector plug 14 and the connector body 12.
Specifically as shown in Figure 1, protection tube 17 is a stainless steel, and through machining, welding back, protection tube 17 ends forms the cavity of a sealing, and thermal resistance temperature element such as film platinum resistor are played a very good protection.Temperature element is encapsulated in the head of this protection tube 17, and the end pin of temperature element is drawn from this protection tube 17 by lead-in wire, and is electrically connected with contact pin on the connector plug 14.
As previously mentioned, an end of the close protection tube 17 of connector plug 14 and temperature element lead-in wire reliably weld and are installed in the end away from protection tube of set bolt 16, and fastening by gland nut 15.End away from protection tube 17 of connector plug 14 is provided with a plurality of contact pins (for example four contact pins), cooperates with the jack of corresponding setting on the connector body 12 and realizes reliable connection fast.
In addition, connector body 12 also is connected with thermal resistance lead 18.As shown in Figure 1, edge and 14 pairs of vertical second directions of slotting first direction of connector body 12 and connector plug, lead 18 is drawn from connector body 12, is transferred to the rear end with the signal long-distance that thermal resistance is measured.In addition, be provided with cable jacket 11, be used to realize the lock sealing of thermal resistance lead 18 in the wire terminals of connector body 12.For example, this cable jacket 11 can be the metallic cable chuck, has cable and compresses O-ring seal, realizes the IP67 sealing of thermal resistance.When the lead disturbance of rear end, vibration can not be delivered to the back panel wiring of thermal resistance 10.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
