A surge protection device includes, in one embodiment, a surge responder operative to engage an inner conductor engager during a protection mode and disengage the inner conductor engager during a normal mode. The surge responder returns to the normal mode from the protection mode without operating intervention to replace or re-engage the surge responder.

A coaxial bus connector has a first end and a second end opposite the first end. The first end has a first positive terminal and a first negative terminal coupled to a primary direct current bus of a primary inverter. The second end has a second positive terminal and a second negative terminal coupled to the secondary direct current bus of a secondary inverter, wherein the coaxial bus connector comprises a dielectric material between a center conductor and a coaxial sleeve to form a snubber capacitor to absorb electrical energy or to absorb voltage spikes.

The present invention relates to the technical field of plugs and sockets for electrical appliances. Disclosed are a surface contact plug and socket, comprising a matching plug and socket; a plug contact piece connected with a plug electric wire is arranged on the lower surface of the plug; and a socket contact piece connected with a socket electric wire is arranged on the upper surface of the socket; when the plug is inserted into the socket, the plug contact piece vertically or obliquely meets the socket contact piece to cause surface contact electrification. The surface contact plug and socket of the present invention employ surface contact between contact pieces, enlarge the contact area and improve current transmission capacity since the plug and socket are of the same size, and therefore the contact is always reliable, and the more the plug and the socket are used, the more reliable the contact is.

An intrinsic safe in-line adaptor with an integrated capacitive barrier for connecting a wireless module with an antenna. The in-line adaptor (e.g., N-type to N-type) can be designed to include an intrinsic safe circuit and the integrated capacitive barrier. The intrinsic safe circuit further includes a multi-layer PCB and the PCB can be potted and sealed with a mechanical metal casing. The intrinsic safe capacitive barrier can be integrated with a coaxial connector and mounted as part of a flameproof enclosure to meet an explosion safety standard and an intrinsic safety requirement. The mechanical metal casing can be isolated by the enclosure (e.g., rubber) to meet isolation requirements. The wireless module can be directly connected with the antenna utilizing the in-line adaptor via the coaxial connector and without any specific cable assembly.

A surge-protected coaxial termination includes a metallic outer body, a center conductor extending through a central bore of the outer body, and a spark gap created therebetween to discharge high-voltage power surges. A plurality of dielectric insulators surrounds the center conductor on opposite sides of the spark gap. High impedance inductive zones surround the spark gap to form a T-network low pass filter that nullifies the additional capacitance of the spark gap. An enlarged portion of a center conductor mitigates deleterious effects of arcing. An axial, carbon composition resistor is disposed inside the outer body, and inside the dielectric insulator to absorb the RF signal, and prevent its reflection.
