发明名称 Cord strain relief device
摘要 An electrical connector having strain relief and integral means for clamping and manually unclamping an electrical cord. The connector includes a housing having a compartment, disposed within a forward portion of the housing, for receiving an electrical device. An array of ratchet teeth is disposed rearward of the forward portion and is disposed circumferentially about an inner wall portion of the compartment. An inner wall portion of the housing disposed between the array of ratchet teeth and a rear entrance aperture of the housing has formed therein a circumferential groove. A member inserted into the housing has a cord clamping component integrally connected to a strain relief component through a bushing component. The bushing component has a pawl engageable with the array of ratchet teeth to provide a ratchet. The cord clamping component has a distal end rotatably fixed relative to the housing adjacent the compartment; a proximal end connected to the bushing and rotatably disposed within the groove; and, a helical spring-like element disposed between the distal end and the proximal end for providing radially compressive forces to portions of an electrical cord passing therethrough, such cord being electrically connected to the electrical device, passing through the bushing, and exiting the electrical connector while passing through the strain relief component. The bushing includes means for manually releasing the cord clamping component.
