Abstract
The utility model discloses a small-stroke leakage test structure which comprises a test rod, a casing, a nameplate, a reed, a substrate and a fixed contact plate, wherein the test rod is fixed on the casing, the reed is welded and fixed on the substrate, the fixed contact plate is arranged opposite to the reed, a pad is arranged on the substrate, and the pad is arranged opposite to the tip of the reed. The small-stroke leakage test structure disclosed by the utility model has a simple structure, a long service life and large electric clearance, can bear high current and is not easy to burn out, false triggering can be avoided, and the service life of a testing mechanism can be over 10000 times; the electric clearance is greatly increased and is much larger than that of a micro switch, and false triggering can be avoided; and due to large electric clearance, the mechanism has reliable insulation and voltage-withstanding performances and is not easy to burn out when high current is broken.
Description
Technical field
The utility model relates to little stroke leakage tests structure.
Background technology
The test component of existing product adopts microswitch, yet microswitch is short serviceable life, and electric clearance is inadequate, withstand voltage deficiency, large electric current by the time burn out easily easily false triggering.Therefore, prior art awaits improving.
The utility model content
The utility model provides little stroke leakage tests structure, and it is short serviceable life to be used for solving the prior art microswitch, withstand voltage deficiency, the problem that fault rate is high.
For solving the problems of the technologies described above, the little stroke leakage tests structure that the utility model embodiment provides, adopt following technical scheme:
Little stroke leakage tests structure wherein, comprises prod, shell, nameplate, reed, substrate, fixed contact plate, and described prod is fixed on the described shell, and described reed is welded on the described substrate and is fixed; The corresponding setting with described reed of described fixed contact plate.
Particularly, be provided with pad on the described substrate, described pad and the corresponding setting in described reed tip.
The little stroke leakage tests structure that the utility model provides, simple in structure, long service life, electric clearance is large, can bear large electric current, is not easy to burn out, and avoids simultaneously false triggering, and mechanism for testing can reach more than 10,000 times serviceable life; Greatly increase electric clearance, be far longer than the electric clearance of microswitch, and can avoid false triggering; Because electric clearance is large, this mechanism insulation resistance can be reliable, and be not easy to burn out when large electric current disjunction.
Description of drawings
Fig. 1 is the structural representation of the 1st embodiment of the described little stroke leakage tests structure of the utility model embodiment.
Fig. 2 is the structural representation of the 2nd embodiment of the described little stroke leakage tests structure of the utility model embodiment.
Embodiment
The little stroke leakage tests structure that the utility model provides, simple in structure, long service life, electric clearance is large, can bear large electric current, is not easy to burn out, and avoids simultaneously false triggering, and mechanism for testing can reach more than 10,000 times serviceable life; Greatly increase electric clearance, be far longer than the electric clearance of microswitch, and can avoid false triggering; Because electric clearance is large, this mechanism insulation resistance can be reliable, and be not easy to burn out when large electric current disjunction.
Below in conjunction with accompanying drawing the little stroke leakage tests structure that the utility model embodiment offers is described in detail.
Embodiment 1:
As shown in Figure 1, little stroke leakage tests structure, wherein, comprise prod 1, shell 2, nameplate 3, reed 4, substrate 5, fixed contact plate 6, described prod 1 is fixed on the described shell 2, and adopts nameplate to carry out waterproof, and described reed 4 is welded on the described substrate 5 and is fixed; Described fixed contact plate 6 and described reed 4 corresponding settings.
The fixed contact plate is powered to substrate, and both sides fixed contact plate (zero line and live wire) is carried out the conducting short circuit by reed, thereby product is threaded off.
The function implementation: produce leakage current by after test spring is contacted with the fixed contact plate, product triggers threads off.
Because the stroke amplification of test spring increases reed and fixed contact plate gap, guaranteed electric clearance, increased the product safety performance.And because the shape of nameplate protection and shell make prod be not easy by false touch to and make the product false triggering.
Embodiment 2:
As shown in Figure 2, little stroke leakage tests structure wherein, comprises prod 1, shell 2, reed 4, substrate 5, fixed contact plate 6, and described prod 1 is fixed on the described shell 2, and described reed 4 is welded on the described substrate 5 and is fixed.
Particularly, be provided with pad 7 on the described substrate 5, described pad 7 and the corresponding setting in described reed 4 tips.
Prod is fixed on the shell; Reed is welded on the substrate and is fixed; The fixed contact plate is powered to substrate, and both sides fixed contact plate (zero line and live wire) is carried out the conducting short circuit by reed, thereby product is threaded off.
The function implementation: under prod on time, reed tip contact substrate pad, product just can trigger dropout.
By the reed shape stroke between reed and the pad is amplified, increased the gap between pad and the reed, increased the security performance of product.And because shell fixing test clavate shape reason must use tiny object to press prod, product could continue to trigger threads off, and avoids the product false triggering.
The little stroke leakage tests structure that the utility model provides, simple in structure, long service life, electric clearance is large, can bear large electric current, is not easy to burn out, and avoids simultaneously false triggering, and mechanism for testing can reach more than 10,000 times serviceable life; Greatly increase electric clearance, be far longer than the electric clearance of microswitch, and can avoid false triggering; Because electric clearance is large, this mechanism insulation resistance can be reliable, and be not easy to burn out when large electric current disjunction.
The above; it only is embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion by described protection domain with claim.
