Description
Technical field
The utility model belongs to data acquisition technical field of auxiliary equipment, relates to matrix foil gauge lead-in wire clip under a kind of hot environment.
Background technology
At present, resistance strain gage has resistant to elevated temperatures and form that is normal temperature, adopts the electrical measuring method structure higher to temperature to carry out paster in the case of a high temperature and measures more difficult.Reason pastes foil gauge in the higher situation of ambient temperature to have certain influence, and especially when electric welding, impact is comparatively large, higher to the operation requirements of technical staff, and more difficult.Just resistance strain gage needs to be connected can to carry out data acquisition by straingauge with wire, in order to ensure connection be close contact together, need wire and resistance strain gage to go between the welding that is connected.Need in the process of welding by wire and lead-in wire complete affixed by welding wire, technical staff will overcome the high impact of ambient temperature when welding, also will consider that welding is closely fixed together, operation easier is larger simultaneously.In high temperature environments, such as in power plant's conduit running region, although pipeline external has done isothermal holding, ambient temperature is still higher.If when technical staff adopts electric welding to weld, be often with a face streaming with sweat.
Utility model content
The purpose of this utility model is to provide matrix foil gauge lead-in wire clip under a kind of hot environment, solves the problem that technical staff's weld strain sheet is very difficult in high temperature environments at present.
The technical scheme that the utility model adopts comprises draw-in groove and caulking groove, draw-in groove is cuboid, on draw-in groove end face with the center line of end face length direction for symmetry axis to have the identical and wire casing of symmetry of two sizes along centerline direction both sides, wire casing is cuboid, the end face of draw-in groove is made to form three highly identical projections, caulking groove is cuboid, caulking groove bottom surface has three cuboid grooves, three cuboid grooves are arranged side by side, the shape of three cuboid grooves is identical corresponding with three of draw-in groove convex shape, can three projections be closely plugged in three cuboid grooves, the two sides height of caulking groove is higher than the two sides height of wire casing, inside edge is provided with bottom two sides, when three projections of draw-in groove are closely plugged in three cuboid grooves of caulking groove, edge is tightly stuck in the bottom edge of draw-in groove, caulking groove is that high temperature resistant and resilient material is made.
Further, the material of caulking groove is plastics or rubber or PVC.
Further, the length of caulking groove is less than or equal to the length of draw-in groove.
The beneficial effects of the utility model are that matrix foil gauge of the present utility model lead-in wire clip can convenient contact resistance foil gauge lead-in wire in high temperature environments, do not need to adopt the connected mode of electric welding formula in the past, conveniently save time.

Fig. 2 is that under a kind of hot environment of the utility model, matrix foil gauge down-lead card clamps groove structural representation.
In figure, 1. draw-in groove, 2. caulking groove, 3. wire casing, 4. cuboid groove, 5. edge.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model as depicted in figs. 1 and 2, comprise draw-in groove 1 and caulking groove 2, draw-in groove 1 is cuboid, on draw-in groove 1 end face with the center line of end face length direction for symmetry axis to have the identical and wire casing 3 of symmetry of two sizes along centerline direction both sides, wire casing 3 is cuboid, the end face of draw-in groove 1 is made to form three highly identical projections, caulking groove 2 is cuboid, caulking groove 2 bottom surface has three cuboid grooves 4, three cuboid grooves 4 are arranged side by side, the shape of three cuboid grooves 4 is identical corresponding with three convex shape of draw-in groove 1, can three projections be closely plugged in three cuboid grooves 4, the two sides height of caulking groove 2 is higher than the two sides height of wire casing 1, inside edge 5 is provided with bottom two sides, when three projections of draw-in groove 1 are closely plugged in three cuboid grooves 4 of caulking groove 2, edge 5 is tightly stuck in the bottom edge of draw-in groove 1, caulking groove 2 is high temperature resistant and resilient material is made, as resistant to elevated temperatures plastics or rubber or PVC.Owing to having elasticity, the edge 5 of caulking groove 2 outwards can break certain distance into two with one's hands, caulking groove 2 is inserted from the top of draw-in groove 1, when three projections of draw-in groove 1 are submerged in three cuboid grooves 4 completely, original shape can be recovered under the effect of elastic force, by the end stuck fast of draw-in groove 1 after edge 5 exceeds the bottom of draw-in groove 1.In like manner, break edge 5 into two with one's hands and can upwards extract caulking groove 2.
During use, two of foil gauge lead-in wires are put into respectively the wire casing 3 of draw-in groove 1, the wire be connected with foil gauge is also put into wire casing 3 respectively, make wire together with lead-in wire close contact, then at insertion caulking groove 2, wire and lead-in wire are tightly pressed in the bottom of wire casing 3 by caulking groove 2, and are firmly stuck on draw-in groove 1, like this lead-in wire of foil gauge and wire are connected into as a whole, can not be reached the object of connection by the mode of welding.
The beneficial effects of the utility model are, can avoid lead-in wire and form touch and cause line short phenomenon.Two lead-in wires of foil gauge are each fills a clip, clip adopts exotic material to make, lead-in wire and wire are got up by clip compact siro spinning technology, electric welding mode in the past need not be adopted like this, solve the impact of temperature on welding, make metering system and means convenient, the accuracy of data can be ensured simultaneously.According to conveniently measurement data in high temperature environments, and can weld by connecing electricity, saving the difficulty of welding.Also can avoid the security risk brought owing to connecing electricity simultaneously.Under higher temperatures environment, technical staff both can complete line operation at short notice, also can avoid adopting electric welding to occur the situation of disconnected weldering.
The above is only to better embodiment of the present utility model, not any pro forma restriction is done to the utility model, every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
