ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an audio jack electrical connector, and particularly to an audio jack electrical connector having a spacer for adjusting the height of the audio jack electrical connector.
With the development of the multimedia computer, audio jack electrical connectors are widely used. Taiwan Patent Application Nos. 82207507; 84215349; 85206217; 85218465 and 86201643 each disclose a conventional audio jack electrical connector comprising a body and a plurality of signal terminals received in the body. A tubular receptacle extends from a front surface of the body for engaging with a plug. Generally, a conventional audio jack electrical connector used for a notebook computer is thicker than other common audio jack electrical connectors. Therefore, the body and the signal terminals must be changed, and the molds used for forming the body and the signal terminals must be accordingly adapted resulting in high production costs.
Thus, a spacer is needed to adjust the thickness of the conventional audio jack electrical connector for reducing the production costs.
BRIEF SUMMARY OF THE INVENTION
A main object of the present invention is to provide an audio jack electrical connector having a spacer for adjusting the thickness of the audio jack connector and reducing production costs of manufacturing an audio jack electrical connector having a different thickness.
To fulfill the above-mentioned object, according to a preferred embodiment of present invention, 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, and each locking element comprises a locking arm and a locking tip. A base of the spacer comprises a top surface and a bottom surface. A pair of posts is formed on the bottom surface for securely positioning the spacer on a circuit board. A pair of locking portions is formed on lateral faces of the base. Each locking portion comprises a recess and a locking block. In assembly, the locking arm is received in the recess and the locking tip engages the locking block. Thus, the body is securely assembled to the spacer.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
