Abstract
The invention provides a contact type switch testing wire. The technical scheme of the utility model is that the contact type switch testing wire comprises a conductive wire, a cylindrical plug terminal and an insulated heat shrinkable tube. One end of the conductive wire is connected with a testing instrument, and the other end of the conductive wire is connected with the cylindrical plug terminal. The insulated heat shrinkable tube is tightly sleeved outside the cylindrical plug terminal and is overlapped with the insulated sheath of the conductive wire. According to the contact type switch testing line, a wire clip of a traditional contact type switch testing wire is replaced by the cylindrical plug terminal, thus the connection between the testing wire and a contact type switch cylindrical terminal is firmer and more reliable, the possibility of the shaking-out of the testing wire is completely eliminated, and the smooth operation of a contact type switch test is ensured. The function of the insulated heat shrinkable tube is to protect the cylindrical plug terminal and the wire core of the conductive wire, and the security of a switch test is improved further.
Description
Technical field
The utility model relates to a kind of p-wire used when the contact type switch is tested, and belongs to technical field of measurement and test.
Background technology
At present, the general p-wire of end with wire clamp that use when transformer station tests the contact type switch, the wire clamp of two p-wires are clipped on two column terminals of contact type switch and just the contact type switch can be accessed to test circuit.Column terminal more intensive (referring to Fig. 1) due to the contact type switch, wire clamp and being connected of column terminal, insecure and exposed metal part was more, therefore the moment wire clamp that closes jumping at switch is easy to come off because being given a shock, then cause short circuit, miscellaneous equipment in contact type switch or test circuit is burnt, cause unnecessary economic loss to transformer station.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of contact type switch testing line that can reliably be connected with the column terminal and be difficult for being short-circuited is provided.
Problem described in the utility model is realized by following technical scheme:
A kind of contact type switch testing line, formation comprises wire, tubular inserting terminal and isolating shrinkable tube, and an end of described wire is connected with testing tool, and an end is electrically connected to the tubular inserting terminal; Described isolating shrinkable tube is tightly placed in tubular inserting terminal outside and overlaps with the insulated hull of wire.
Above-mentioned contact type switch testing line, the cylinder of described tubular inserting terminal head and the column terminal interference fit of contact type switch also are provided with axial expansion or contraction joints, its afterbody and conductor compression jointing.
Above-mentioned contact type switch testing line, the crimping point of described tubular inserting terminal and wire is the scolding tin reinforcement point.
The utility model utilizes the tubular inserting terminal to replace the wire clamp of traditional contact type switch testing line, make p-wire more solid and reliable with being connected of contact type switch column terminal, thoroughly eliminate p-wire and shaken the possibility that falls, guaranteed carrying out smoothly of contact type switch test.The effect of isolating shrinkable tube is that the core of tubular inserting terminal and wire is protected, and further improves the security of switch testing.
The accompanying drawing explanation
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is that the column terminal of contact type switch is arranged schematic diagram;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the structural representation of tubular inserting terminal;
Fig. 4 is the connection diagram of tubular inserting terminal and wire;
Fig. 5 is the connection diagram of the utility model and contact type switch.
In figure, each list of reference numerals is: 1, contact type switch case; 2, column terminal; 3, isolating shrinkable tube; 4, tubular inserting terminal; 5, core; 6, wire.
Embodiment
Referring to Fig. 1～Fig. 5, the utility model consists of isolating shrinkable tube 3, tubular inserting terminal 4 and wire 6, and tubular inserting terminal 4 is crimped on the end of wire 6, and isolating shrinkable tube 3 is enclosed within tubular inserting terminal 4 outsides and partly overlaps with the insulated hull of wire 6.
The making of p-wire
Main material: two, wire, 4 two of tubular inserting terminals.
Manufacturing process: the insulated hull of wire one end is removed, wire termination is placed in the U-shaped groove of tubular inserting terminal 4 afterbodys, with crimping apparatus, the two is crimped on together to (also can adopt welding manner), finally on tubular inserting terminal 4, put isolating shrinkable tube 3 heating, make to be tightly placed on tubular inserting terminal 4 after isolating shrinkable tube 3 contractions.
The advantage of this examination line
Easy to use, be easy to carry about with one, wiring is safe and reliable, and the progress that can accelerate to construct can guarantee the safety of the person, equipment again.
