A high voltage connector, connected to a device, that experiences a reduced electromagnetic interference (EMI), avoids galvanic corrosion of dissimilar metals within or without a fluid environment, and provides an effective electrical ground system. The connector includes an outer housing assembly, an inner housing mounted inside the outer housing, a set of cable reinforcement retainer assemblies secured inside the inner housing, a back cover through which the cables respectively slide along and covers a central opening of the outer housing, a braided shield covering the cables, and a clamp that connects the shield onto the outer housing. When assembling the high voltage connector, the outer housing is mounted onto the device; the inner housing is secured inside the outer housing; the set of cable reinforcement retainer assemblies with associated cables is secured in and extends in a substantially vertical direction from the inner housing; a back cover is slid along the cables, and enters and covers a central opening of the outer housing; and a braided shield is mounted and connected to the outer housing by a clamp.

An electromagnetic interference (EMI) grounding protection method for a connector assembly using a conductive housing. The method includes the steps of: conducting the EMI generated by a source towards a metallic braided shield, the metallic braided shield being secured and mounted onto the conductive housing by a metallic clamp; conducting the EMI from the metallic braided shield to the metallic clamp and to the conductive housing, the conductive plastic housing being mounted onto a metallic device by at least a metallic bolt and the bolt being accommodated within a corresponding metallic compression limiter; and thereafter, conducting the EMI: (1) from the conductive housing through the metallic compression limiters and through their respective bolts, and ultimately to the metallic device, and (2) from the conductive housing directly through conductive pads thereof, and ultimately to the metallic device.

A coaxial cable connector includes a body configured to engage a coaxial cable having a conductive electrical grounding property, a post configured to engage the body and the coaxial cable when the connector is installed on the coaxial cable, a nut configured to engage an interface port at a retention force, and a retention adding element configured to increase the retention force between the nut and the interface port so as to maintain ground continuity between the interface port and the nut when the nut is in a loosely tightened position on the interface port.

A crimp crystal head includes a base, golden plates, a circuit board, crimping terminals and a fixing seat. The base has insertion slots. The golden plates are separately placed in the insertion slots. The circuit board is disposed in the base. Two ends of the circuit board connect to the golden plates and have terminal holes, respectively. Each crimping terminal has a wiring hole for being inserted by a twisted pair wire and a crimping trough for fixing and connecting the twisted pair wire. The wiring hole communicates with the crimping trough. Each crimping terminal has a fixing bar inserted into the terminal hole with interference fit. The fixing seat is installed on the circuit board and has terminal trenches and inserting holes separately communicating with the terminal trenches. The crimping terminal is inserted into the terminal trench. The insertion hole is inserted by the twisted pair wire.
