Abstract
The utility model relates to a high-pressure hydraulic giant for flushing a high-density interconnection circuit board. The lower portion of the rear end of a connecting piece and the rear end of a giant body are respectively connected with two ends of a microswitch. The microswitch controls a water pump through a relay. According to the high-pressure hydraulic giant, the lower portion of the rear end of the connecting piece and the rear end of the giant body are respectively connected with two ends of the microswitch which is connected with a coil of the relay in series. A normally-opened contact of the relay is connected with a power end of the water pump in series. When an operator pulls a trigger, the connecting piece moves backwards and enables the mocroswitch to be closed. Next, the coil of the relay is electrified, enables the normally-opened contact to be closed and then enables the water pump to run. Consequently, high-pressure water rushes out. When flushing operations are not needed, the normally-opened contact is disconnected, and the water pump stops running. Working safety of the water pump is guaranteed.
Description
Technical field
The water resource that the utility model belongs in the circuit board technique is utilized technical field, especially a kind of high-density interconnected circuit board flushing giant.
Background technology
Circuit board grinds in copper, the welding resistance bubble sheet operation in the abrasive band and all uses giant to wash, the structure of this giant is as shown in Figure 1: comprise rifle body 1, handle 5, trigger 2 and brace 3, below, the rear end mounting knob of described rifle body, the rifle body both sides hinge dress trigger of this handle front side, the brace rear end institute load bar of hinge dress connects rifle body rear end on this trigger, the handle lower end is provided with water inlet 6, this water inlet is communicated with the water source by water pump, when operating personnel pull trigger to handle, connecting rod is communicated with the delivery port of water inlet and rifle body front end, and water under high pressure is gone out.
Above-mentioned water pump is at first switched on, then the hand-held handle of operating personnel washes, but operating personnel unclamp trigger by often forgetting the power supply that switches off the pump, because high pressure water circuit opens circuit, the build the pressure damage of the water-stop that causes of water pump often occurs, burn-down of electric motor perhaps occurs.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of high-density interconnected circuit board rational in infrastructure, work safety to wash and uses giant.
The technical scheme that the utility model is taked is:
A kind of high-density interconnected circuit board flushing giant, comprise rifle body, trigger and brace, the rear end hinge dress trigger of described rifle body, the brace rear end of hinge dress connects rifle body rear end on this trigger, it is characterized in that: be connected the rear end and connect respectively the two ends of a microswitch in described brace rear end below with the rifle body, this microswitch passes through a Control water pump.
And described microswitch is connected with a relay coil, and a normally opened contact of this relay is connected with the power end of water pump.
Advantage of the present utility model and good effect are:
In the utility model, be connected the rear end and connect respectively the two ends of a microswitch in brace rear end below with the rifle body, microswitch is connected with a relay coil, a normally opened contact of this relay is connected with the power end of water pump, when operating personnel pull trigger, brace moves backward and makes microswitch closed, then relay coil gets the electric normally opened contact closure that makes, water pump is started working, water under high pressure is gone out, and when need not to wash, normally opened contact disconnects, water pump quits work, and has guaranteed the work safety of water pump.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
The specific embodiment
Below in conjunction with embodiment, the utility model is further specified, following embodiment is illustrative, is not determinate, can not limit protection domain of the present utility model with following embodiment.
A kind of high-density interconnected circuit board flushing giant, shown in Fig. 1～2, comprise rifle body 1, trigger 2 and brace 3, the rear end hinge dress trigger of described rifle body, the brace rear end of hinge dress connects rifle body rear end on this trigger, innovation of the present utility model is: be connected the rear end and connect respectively the two ends of a microswitch 4 in described brace rear end below with the rifle body, this microswitch passes through a Control water pump.
In the present embodiment, microswitch is connected with a relay coil 7, and a normally opened contact 8 of this relay is connected with the power end of water pump 9.
In the utility model, be connected the rear end and connect respectively the two ends of a microswitch in brace rear end below with the rifle body, microswitch is connected with a relay coil, a normally opened contact of this relay is connected with the power end of water pump, when operating personnel pull trigger, brace moves backward and makes microswitch closed, then relay coil gets the electric normally opened contact closure that makes, water pump is started working, water under high pressure is gone out, and when need not to wash, normally opened contact disconnects, water pump quits work, and has guaranteed the work safety of water pump.
Claims (2)
1. a high-density interconnected circuit board washes and uses giant, comprise rifle body, trigger and brace, the rear end hinge dress trigger of described rifle body, the brace rear end of hinge dress connects rifle body rear end on this trigger, it is characterized in that: be connected the rear end and connect respectively the two ends of a microswitch in described brace rear end below with the rifle body, this microswitch passes through a Control water pump.
