Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
The structure of the detection device of quick-action switch contact resistance provided by the utility model is as shown in Figure 1-Figure 3, including peace
It fills bottom plate 1 and fixes the installing mechanism of quick-action switch, contact mechanism 4 is connected with by elastomeric element on mounting base 1, is contacted
The upper surface of mechanism 4 is connected with pressing plate 3, and Power Component is provided on mounting base 1, and Power Component is connected and drives with pressing plate 3
Dynamic pressure plate 3 is mobile relative to mounting base 1.The structure of contact mechanism 4 is as shown in figure 4, contact structures 4 include and quick-action switch
Multiple probes that normally open end, normally closed end position are oppositely arranged, probe, which is connected to instrument for measuring DC resistance by conducting wire 17, (schemes not
Show).In the present embodiment, Power Component is cylinder 2.
Further, referring to fig. 4, contact mechanism includes slide 8, and sliding block 9, sliding block 9 and mounting base are provided in slide 8
It is connected between 1 by elastomeric element, and sliding block 9 moves in slide 8, and multiple mounting grooves, multiple mounting grooves are provided in sliding block 9
Corresponding with the normally open end of quick-action switch, normally closed end position, the probe of contact mechanism 4 is set in mounting groove.And two probe groups
At a probe groups, it is provided with felt pad 13 between two probes of probe groups, probe groups are sheathed in insulating sheath 11, insulation
Sheath 11 is sheathed in floating bushing 10, and floating bushing 10 is set in mounting groove.Mounting groove where floating bushing 10 is obliquely installed,
While sliding block 9 slides up and down, floating bushing 10 also does slanting upper and lower sliding in sliding block 9, and requires floating bushing 10 upward
Strength be less than the upward strength of sliding block 9, i.e. the first upward sliding of sliding block 9, then floating bushing 10 could upward sliding, it is main former
Because being that probe and quick-action switch shell is avoided to generate interference.It is same because 10 elastic force of floating bushing is small floating when slide downward
Set 10 will first slide downward.In order to adjust the distance between slide 8 and quick-action switch, therefore pad is set on mounting base 1
Slide 8 is set in feet 7 by foot 7.In order to shorten the length of elastomeric element between sliding block 9 and mounting base 1, in sliding block 9
Backing plate 16 is arranged in bottom, and elastomeric element is set between sliding block 9 and backing plate 16.
Contact can damage probe firmly when moving up and down in order to avoid sliding block 9, while guarantee contact of the probe with quick-action switch
Point reliable contacts, are also equipped with elastomeric element between the bottom and floating bushing of mounting groove.In the present embodiment, elastomeric element is to reset
Spring 15.
Installing mechanism includes the mounting plate 5 being vertically arranged on mounting base 1 and quick-action switch is fixed on mounting plate 5
On mounting pin 6.
In the present embodiment, there are four mounting groove is arranged altogether, is located in the middle two mounting grooves and is vertically arranged, in probe
Group is only wrapped up by insulating sheath 11, and each probe groups include two short probe 14, and a/b, c/d probe groups are that detection normal-closed end draws
Line；And two mounting grooves for being located at two sides are oppositely arranged and the angle horizontal by 107 °, in probe groups by insulating
Sheath 11 wraps up, and insulating sheath 11 is then wrapped in floating bushing 10, and each probe groups include two long probes 12, e/f, g/h
To detect normally open end lead.And in the present embodiment, two long probes 12 and short probe 14 of probe groups be byCopper
Line is divided into two to obtain, and difference is then that length is longer than short probe 14 since 12 oblique movement stroke of long probe is longer, and
Since therefore length is shorter for vertical motion, internal diameter is packed into behind centre plus felt pad 13 is short probe 14Insulating sheath 11
Interior, insulating sheath 11 is nylon material.
When detection, two on tested quick-action switchMounting hole is inserted and fixed to mounting plate 5 by mounting pin 6
On, subsequent start-up cylinder 2 acts upwards, upward sliding under the action of reset spring 15 of sliding block 9, while intermediate two mounting grooves
Interior short probe groups also also slide straight up in mounting groove by the effect of reset spring 15, long probe in the mounting groove of two sides two
Group is also slided under the action of reset spring 15 in mounting groove obliquely, and can be abutted against with the normally open end of quick-action switch, normal-closed end
Touching, instrument for measuring DC resistance obtain the contact resistance numerical value of quick-action switch；Then cylinder 2 drives pressing plate 3 to oppress sliding block 9 and transports downwards
Dynamic, the normally open end of probe groups and quick-action switch, normal-closed end disengage, and remove the quick-action switch, install next quick-action switch
After restart to test.
