The relative probe set of described probe has elasticity.
Compared to prior art, the clamp structure of the utility model test fuse internal resistance is simple, easy to operate, reduced the injury to product.In addition, by detachable module is set on base, because Thermal Cutoffs has multiple model, therefore can make a kind of module that adapts with it at every kind of model, the overall dimensions that are module adopt unified standard, and the placement size of the die cavity in the module is made according to dut temperature fuse gauge size, adopts this dismountable inserted module, improved versatility of the present utility model greatly, made that its applicability is stronger.
Moreover, owing to blowning installation is arranged, and the storage box that on base, designs, tested fuse can be taken out very easily after testing in the design of the bottom surface of the die cavity of module, tested fuse is conveniently put into die cavity, from big raising product test efficient.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is the upright structural representation of the anchor clamps of the utility model test fuse internal resistance.
Fig. 2 is the probe set in the anchor clamps of the utility model test fuse internal resistance and the cross-sectional view of the matching relationship between the upper and lower clamping plate.
Embodiment
Please together with reference to figure 1 and Fig. 2, the utility model is used for testing the anchor clamps of fuse internal resistance, be provided with base 1, on this base 1, be fixed with an opened type objective box 2, on these objective box 2 bottoms, removably be fixed with a module 3, and then by this objective box 2 this module 3 is fixed on the described base 1, and the top of this module 3 is concordant with the lower surface of this objective box 2, a side of this objective box 2 is formed with and is used for gap 4 that the tested object that finishes is easy to transfer to.In addition, be formed with the die cavity 5 that is used for placing tested fuse in this module 3, therefore utilize this objective box 2, can tested fuse is placed in this objective box 2 earlier, and then it is advanced in the die cavity 5 that is placed on module 3 in regular turn test, saved an action of picking up, putting down.Be provided with a breather line 6 that connects with this die cavity 5 in these module 3 bottoms; This base 1 is fixed with a cylinder 8 by support 7 above this module 3, the gas circuit of this cylinder 8 (scheming not shown) is connected with gas source interface by a solenoid directional control valve, also pass through button, relay simultaneously, and the gas path on-off that this solenoid valve advances this cylinder of control is controlled in the cooperation between the time relay.Wherein, this solenoid valve is provided with the gas outlet as sound suppressor, the breather line 6 of the bottom of described die cavity 5 is communicated with the gas outlet of the sound suppressor of this solenoid valve by an air pressure valve (scheming not shown) of regulating the air pressure size, and is excessive so that control is blown, and prevents to make product to splash away.Therefore after testing internal resistance, when the push rod bottom out of cylinder 8, can utilize the air pressure of this sound suppressor that Thermal Cutoffs is blown out from module (because fuse is very little and very light), the tested fuse of can taking very easily, and improved production efficiency effectively.The push rod end of this cylinder 8 is fixed with the probe set 9 that is provided with probe 91 and (belongs to standard component, its inner structure is known content, so be not described in detail at this), one end of the probe 91 in this probe set 9 (is the internal resistance test device device by lead and external testing instrument, this one is known content, not shown) be electrically connected, the control of the other end of this probe 91 by the push rod of cylinder 8 can contact with the both sides of tested fuse in the described die cavity 5, forms electric loop with described external testing instrument simultaneously.Wherein, these probe 91 relative probe sets 9 have elasticity, and probe 91 is connecing with contacting can make things convenient for fully when tested fuse electrically contacts like this, and has strengthened the serviceable life of probe 91.
In addition, this probe set 9 train wheel bridge 10 that is stacked together, lower plate 10 ' clamp and the end that is fixed on the push rod of this cylinder 8 (certainly, also can this probe set 9 be fixed in the block by the mode of injection mo(u)lding, by this block probe set 9 is fixed on the end of the push rod of cylinder 8 again), wherein these probe set 9 outside protrusions are formed with a bulge loop 93, this train wheel bridge 10, lower plate 10 ' is in corresponding position, be formed with the perforation that can penetrate respectively for the two ends of probe set 9, the diameter of this perforation wherein also forms the groove 11 that protrudes for probe set 9 less than the external diameter of the bulge loop 93 on this probe set 9 at the top of this train wheel bridge 10.In addition, train wheel bridge, lower plate 10 use insulating material to make, and are for fear of causing short circuit.
The new concrete operations of this practicality are: by pressing down knob, connect condenser, beginning control time condenser and solenoid valve, at this moment solenoid valve energising, the push rod of control cylinder 8 begins to press down, the nickel sheet at the tested fuse two ends in probe 91 and the die cavity 5 in the probe set 9 is contacted, and keep certain duration of contact, when the push rod bottom out of cylinder 8, utilize the air pressure of sound suppressor directly to receive on the breather line 6, promptly blowing just begins to start, and tested fuse is blown afloat from die cavity 5, and the tested fuse that will be blown afloat is dialled in the pulp-collecting box from the gap 4 of objective box 2 then.
