Abstract
Abstract A releasable electrical connector is composed of two halves or components, one being of conventional construction and having a shell provided with a plurality of socket contacts and radially directed bayonets that are latched with the other half or component constructed in accordance with the invention. After the bayonets are inserted into slots formed in a pawl carrier sleeve in the second connector half, the carrier sleeve is angularly shifted in a direction to effect latching of the pawls with the bayonets. The pin contacts are mounted in a rubber insert contained in a shell belonging to the second connector half; a grounding ring encircles the last-mentioned shell. Through helical ramp grooves formed on the exterior of the shell and antifriction rollers extending inwardly from an encircling drive sleeve, the rectilinear movement required for shell advancement is derived from rotation of the drive sleeve. The shell advancement first results in the spring tines of the grounding ring moving into the shell of the first connector half, then the entry of the pin contacts into the socket contacts, and finally a slight facial compression of the rubber insert in which the pin contacts are mounted. The tendency for the rubber insert to expand provides a seal and in conjunction with a detent formed at one end of each of the ramp grooves into which the rollers move prevents inadvertent retraction of the second shell and its pin contacts. Tension springs normally bias the shell into a retracted position, but the action of these springs is easily overcome during the coupling process. Relatively rotatable pin and groove means on the carrier and drive sleeves become effective at the end of the coupling procedure to assure that the pawls and bayonets will remain latched until their release is desired. An indicator, capable of being both seen and felt, is forced outwardly to signify that the two halves are fully mated and latched. A lanyard is anchored to the improved connector half and a 360* swiveling can be realized. When a predetermined load is applied to the two halves, they pull apart. A backshell can be securely attached in any angular position to the second connector half.
