  • Patent number: 6257934
    Abstract: An audio jack electrical connector comprises a body retaining a plurality of signal terminals and a spacer defining a plurality of receiving holes for retaining connection contacts. The signal terminals extend beyond a bottom surface of the body for engaging with the corresponding connection contacts of the spacer. A tubular receptacle is defined through the body, and a projection portion of the receptacle is formed on a front surface of the body for engaging with a plug for audio signal transmission. A pair of locking elements is formed on lateral edges of the body. Each locking element comprises a locking arm and a locking tip. A pair of locking portions is formed on lateral faces of the spacer. Each locking portion comprises a recess and a locking block. In assembly, the locking arm is received in the corresponding recess and the locking tip engages the locking block. Thus, the body is securely assembled to the spacer.
