2-30mm
2, therefore relative existing product, its welding area is little, thus reduces cost, also avoids the uneven situation of welding simultaneously.
As further program of the utility model: the junction of described upper cover and base is provided with sealing ring, increase overall sealing by sealing ring.
As the utility model further scheme: the conductive electric wire sectional area size of described cable is 2.5mm
2-4mm
2.
As the utility model further scheme: described base and upper cover all adopt engineering plastics to make, and bulk strength is high, not easily occur damaging.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple and reasonable, use operation very convenient, effectively and fast can realize effective docking of equipment, equipment is also more convenient in the process of actual installation simultaneously, entirety is very small and exquisite simultaneously, not only be applicable to producing, be applicable to installation among a small circle simultaneously, therefore avoid the situation of equipment waste, simultaneously relative existing product, pressing block welding area is little, not only reduce cost, also avoid the uneven situation of welding simultaneously.
