The invention relates to a wall element for a magnetically shielded room and to a magnetically shielded room. The wall element comprises at least one first layer (1) which is formed of metal plate having a high electrical conductivity, and at least two layers, a second layer (2) and a third layer (3), which consist of metal plates having a high magnetic permeability. The layers (1, 2, 3) are superimposed one on top of another in surface contact with each other without any separating air gaps, so that each first layer (1) having a high electrical conductivity lies between each second (2) and third layers (3) having a high permeability substantially in surface contact with the second and third layers, the layers together forming a compact structure in which the product (σ×μ) of electrical conductivity (σ) and permeability (μ) is maximized so as to minimize the penetration depth of magnetic interference.

A laminar flow, wet electrostatic precipitator (ESP) with planar collecting electrodes preferably made of membranes, such as a woven silica fiber. The collecting electrodes are spaced close to planar discharge electrodes to promote laminar flow (Re<2300). Charging electrodes are positioned upstream of the wet ESP to charge the particulate entering the wet ESP to promote collection. The wet ESP is preferably downstream from a conventional turbulent dry ESP for collecting a substantial portion of the larger particulate in the gas stream prior to the gas stream entering the wet ESP.

An electrical contact element for a car charging plug connector is disclosed, which electrical contact element has a contact part and a connection part, wherein the connection part can be connected to an electrical conductor of a cable. Cooling liquid can be delivered to the contact element. As a result, the heat produced on the contact element is extracted directly.

The invention relates to a manufacturing device of a cable connector employing electronically controlled grating linkage. A base plate and a top cover plate are fixedly supported through a vertical arm lever; a rail bar is fixed at the inner side of the vertical arm lever; a sliding block is erected on the rail bar and is fixed to a pressure plate through a connector; a soldering tin cavity is arranged at the center position of the pressure plate; an electric gas bar is arranged at the center position of the top cover plate; the tail end of a bar member of the electric gas bar is fixed on the soldering tin cavity; and a tin injection contact is fixed at the lower part of the pressure plate and runs through the soldering cavity through a metal conduit. Tin and a tin flux in the soldering tin cavity can automatically flow into a cable clamp easily through the gravity through the mode that the soldering tin cavity, the tin injection contact, a fixed hole and a tin outlet bath run through one another, so that the cable clamp, a cable chuck and a cable are fused into a whole; a good electric conductor is achieved; and by adopting the working mode that a grating is linked with the electric gas bar, an accident of hand injury caused by misoperation of an operator can be avoided.
