Description
Technical field
The utility model relates to the three-dimensional terminal block of a kind of right-angled intersection, for needing the electrical connection between the wire that seals.
Background technology
In many occasions, such as under water, need from hermetically-sealed construction, draw wire or to lead-in conductor in hermetically-sealed construction, this just needs to seal conductor leading.Traditional conductor leading Sealing Technology, cable is introduced in hermetically-sealed construction by general all employing, then in interior welds, or hinge joint, or wrap up in insulating tape, or heat-shrink tube thermoplastic, cable is then with sealing O type circle by pressure by cable sheath press seal, this structure, can accomplish waterproof action really, but hermetically-sealed construction inner chamber and external environment condition still communicate, because the inner many bare copper wires of cable multiple conducting wires and each root wire or inside and outside UNICOM, the inner electrical equipment of the hermetically-sealed construction that this stops for working for a moment for a moment, be in the state of a cold heat, be easy to form dew condensation phenomenon in inside, make hermetically-sealed construction inside produce aqueous vapor and cause the device damage such as electrical equipment.And cable joint is because be stained with aqueous vapor and the reason of energising, through oxide etch after a while, also can produce oxidation breaking phenomena, cause the device damage in hermetically-sealed construction normally to use.
The principle that condensation produces: for submersible machine and light fixture.Motor or light fixture are when indoor assembling completes, in inner chamber, relative humidity is at 40-50%, when motor runs, high temperature can be produced in inner space, the air bulbs of pressure become large, because equilibrium principle, gas pressure in cavity increases, need to overflow outward to reach internal and external pressure balance, at this moment, because the inner many bare copper wires of cable multiple conducting wires and each root wire or inside and outside UNICOM, gas will overflow, inner and outer air pressure is until balance, simultaneously because interior cavity temperature raises, the relative humidity of air declines, such as drop to 10%, in order to inside and outside wetting balance can be reached, at the edge of rubber seal water, the place of cable adapter, what water can evaporate quickly (can become dry) at once, increase the absolute magnitude of steam, the relative humidity in chamber and the external world is made to reach balance.When light fixture or motor do not run, to such an extent as to cavity temperature cooling, a negative pressure can be formed in chamber, so extraneous malaria flows in cavity, and the state of the relative humidity balance reached because temperature raises in original chamber, because temperature cooling is broken, cooling makes relative humidity in chamber become suddenly large, when exceeding saturated or encounter colder material, just there is condensation.
Utility model content
The purpose of this utility model is to provide the three-dimensional terminal block of a kind of right-angled intersection, the terminal block of two planes can be formed the three-dimensional terminal block of right-angled intersection through simple grafting, solder joint contact area is larger, more reliably solid, stop rosin joint, can not come off by solder joint, because there is terminal block to isolate between solder joint and solder joint, can not unexpected short circuit between each pad, insulation property are higher, safer, need sealing and electrical connection between the comparatively moist wire of environment for being used in, reliability improves greatly.
For achieving the above object, the utility model adopts following technical scheme:
The three-dimensional terminal block of a kind of right-angled intersection, comprise upper and lower two terminal block unit, each described terminal block unit comprises a terminal block, the left side in described terminal block front is provided with left conducting strip, the right side in terminal block front is provided with right conducting strip, vertically open slot is provided with between left conducting strip and right conducting strip, the groove width of open slot equals the thickness of terminal block, two described upper wiring board unit and lower terminal block unit are plugged in together by respective open slot right-angled intersection, form the three-dimensional terminal block of right-angled intersection.
The left side of described terminal block reverse side is also provided with left conducting strip, and the right side of terminal block reverse side is also provided with right conducting strip.
Upper and lower two terminal block cellular constructions are identical, and are rectangle.
Described terminal block is made up of printed substrate, and described left conducting strip and right conducting strip are made up of the conductive layer on printed substrate.
Be arranged with fin at the middle part at two ends, described terminal block left and right, the end face of described fin is circular arc and suitable with the inwall of hand-hole to be installed.
The upper and lower terminal block unit be plugged in together is divided into four sectors by terminal block, is welded with upper and lower two wires between two conducting strips of each sector.
After the three-dimensional terminal block of described right-angled intersection loads described hand-hole to be installed, fill with in hand-hole to be installed and establish fluid sealant.
Compared with prior art the beneficial effects of the utility model are: owing to adopting technique scheme, the terminal block of two planes can be formed the three-dimensional terminal block of right-angled intersection through simple grafting, make the wire welded on conducting strip, separated by terminal block, the solder joint of the three-dimensional terminal block of right-angled intersection and plane phase of solder joint ratio, have the following advantages:
1, solder joint contact area is larger;
2, solder joint is more reliably solid, stops rosin joint, can not come off by solder joint;
3, between solder joint and solder joint because there is terminal block isolate, can not unexpected short circuit between each pad, insulation property are higher, safer, and need sealing and electrical connection between the wire of environment comparatively humidity for being used in, reliability improves greatly.
Further beneficial effect is: terminal block adopts printed substrate to make, and draw materials easily, easy to process, cost reduces greatly.Arrange fin, be conducive to the assembling of the three-dimensional terminal block of right-angled intersection and hand-hole to be installed, for underwater sealing wiring, adopt circular hole encapsulating method, the upper and lower end of fin all can be full of fluid sealant, and seal more tight, sealing property is better.
