Specific embodiment
With reference to the accompanying drawings and examples, the utility model is described in detail.
Embodiment one, PTC heating strip insulation pressure resistant testing device, referring to Fig.1, including clamping plate group 1 and insulation pressure resistance are surveyed
Try instrument 2.Its middle clamp plate group 1 includes bottom plate 11 and pressing plate 12, and the upright projection of bottom plate 11 and pressing plate 12 is in rectangle, and the two is big
It is small essentially identical.Bottom plate 11 and 12 side of pressing plate are hinged by hinge, and hinged direction is longitudinal.Bottom plate 11 is located at pressing plate
12 lower section is fixed on suitable station.
The pressure tester 2 that insulate includes the prod of body, the ground connection conductive clip of connection body and connection body.Pressing plate
12 end face upward is fixedly connected with conducting ring, and the earth clip of insulation pressure tester 2, which is clamped on conducting ring, is electrically connected to pressing plate
12, pressing plate 12 is conductive, completes ground connection.
In use, multiple PTC heating strips are placed side by side on bottom plate 11 by user, then rotating pressing plate 12 is pressed in it
On PTC heating strip, the conducting wire of PTC heating strip stretches out pressing plate 12；Subsequent user need to only hold the test of insulation pressure tester 2
It is extended in repeated multiple times on outer conducting wire streak by stick from PTC heating strip；When some PTC heating strip is unqualified, occur
Electrical leakage problems, insulation pressure tester 2 issues prompt information prompt user or user observes known to its display interface.For
Convenient to use, the insulation selection of pressure tester 2 has the insulation pressure tester of sound and light of alarm.
When referring to Fig.1, due to aforesaid operations, prod the leading in PTC heating strip using insulation pressure tester 2 is needed
It is streaked on line, and conducting wire has certain rigidity, this causes when prod streaks conducting wire, and part PTC heating strip is by with askew dry
It disturbs prod to test other PTC heating strips, therefore briquetting 4 is set.Briquetting 4, which is adopted, to be made from an insulative material, and is pacified at an upper portion thereof
Dress is fixed with handle 41.
After pressing plate 12 pushes down PTC heating strip, user can hold handle 41 and briquetting 4 is pressed on pressing plate 12, then
It is mobile to briquetting 4 while prod is mobile, so that pressing plate 12 pushes down PTC heating strip and prevents its moving influence test effect.
Referring to Fig.1, it when testing PTC heating strip, due to needing to be horizontally arranged on bottom plate 11, and needs
The case where conducting wire for occurring some PTC heating strip when prod being avoided to streak is not contacted, so it is additionally provided with leveling straight panel 3,
Leveling straight panel 3 is in long plate shape.
In use, leveling straight panel 3, which is placed in PTC heating strip, does not have the opposite side of conducting wire, and contradicts and kept on bottom plate 11
The state parallel with 11 side of bottom plate；Multiple PTC heating strips need to only be arranged and be opened by user later, and end is kept to contradict leveling
The state of straight panel 3, at this time PTC heating strip marshalling, and conducting wire are also relatively neat, thereby may be ensured that follow-up test stick
Streak test effect when conducting wire.
Referring to Figures 1 and 2, the thickness for leveling straight panel 3 is less than the thickness of PTC heating strip, is using to level straight panel 3
After can be placed directly on bottom plate 11, so as to user carry out subsequent operation.
Side slot 31 is offered in the side of leveling straight panel 3, side slot 31 is located at side when leveling straight panel 3 is laid flat, and it is carried on the back
Center side from leveling straight panel 3 is in hatch frame.
The setting of side slot 31 can be convenient user and pick up it from bottom plate 11, while will not be to neat PTC heating strip
It causes to hinder.
Use process:
1, multiple PTC heating strips are picked up, it is tentatively placed on bottom plate 11, guarantee the end direction one of PTC heating strip
It causes (have conducting wire one end outwardly)；
2, finger contradicts 31 open side of side slot, and leveling straight panel 3 is picked up from upper plate 11；
3, the position of adjustment leveling straight panel 3, places it in the one end of PTC heating strip without conducting wire, 11 side of keeping parallelism bottom plate
Side, and contradict the state of bottom plate 11；
4, each PTC heating strip is separated, and its one end without conducting wire is made to contradict leveling straight panel 3 respectively, with proper alignment
Multiple PTC heating strips；The conductor part of multiple PTC heating strips stretches out pressing plate 12 at this time；
5, rotation pressing plate 12 makes it push down PTC heating strip, holds handle 41 later, briquetting 4 is moved on pressing plate 12；
6, insulation pressure tester 2 is opened, the prod being attached thereto is held, by prod from multiple PTC heating strips
Completion test is streaked on conducting wire.When some PTC heating strip leaks electricity the problem of, insulation pressure tester 2 issues prompt information
Prompt user.
Embodiment two, PTC heating strip insulation pressure resistant testing device, referring to Fig. 3, the difference with embodiment one is, levels
Straight panel 3 is connected on bottom plate 11, and its holding is placed in the one end of PTC heating strip without conducting wire.User need not repeat to adjust at this time
The position of straight panel 3 is leveled, it is relatively convenient to operate.
Referring to Fig. 3 and Fig. 4, since the PTC heat generating member length of different size might not be identical, if leveling straight panel 3 at this time
Position fix, there are problem when this causes to test part PTC heating strip, validity test can not be carried out, thus will leveling it is straight
Plate 3 is set as sliding and is connected to bottom plate 11, and the glide direction for leveling straight panel 3 is the length direction of PTC heating strip, to adapt to
The PTC heating strip of different length.
Sliding block 5 is formed in the lower part of leveling straight panel 3, the sliding slot 111 for agreeing with sliding block 5, sliding slot are offered on bottom plate 11
111 tops and open-ended；Sub- 111 open end of sliding slot of sliding block 5 is divided into sliding slot 111, to realize that leveling straight panel 3 and bottom plate 11 are sliding
Move connection.
Referring to Fig. 3, the movement of slide plate 3 is exchanged for convenience of user, is offered on leveling 3 top of straight panel for user's finger
The kerve 32 protruded into, the side opening upward of kerve 32.
Use process:
1, multiple PTC heating strips are picked up, it is tentatively placed on bottom plate 11；According to the length of PTC heating strip to leveling
The sliding of straight panel 3 places it in suitable position；
2, it keeps the position of leveling straight panel 3 constant, separates multiple PTC heating strips, contact at its one end without conducting wire
Straight panel 3 is leveled, achievees the purpose that neat multiple PTC heating strips；
3, rotation pressing plate 12 makes it push down PTC heating strip, holds handle 41 later, briquetting 4 is moved on pressing plate 12；
4, insulation pressure tester 2 is opened, the prod being attached thereto is held, by prod from multiple PTC heating strips
Completion test is streaked on conducting wire.When some PTC heating strip leaks electricity the problem of, insulation pressure tester 2 issues prompt information
Prompt user.
In summary: the utility model can be convenient staff and carry out insulation voltage-withstand test to the heating strip of PTC, thus
Working efficiency can be improved.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
