Audio jack connector with small size for space saving

摘要

An audio jack connector (100) includes an insulative housing (1), a first contact (21) and a second contact (22) retained in the insulative housing. The insulative housing defines a receiving channel (14). The first contact includes a first retaining portion (211), a first soldering portion (212) bent from the first retaining portion, and a first contacting portion (213) extending from the first retaining portion. The second contact includes a second contacting portion (221) extending into the receiving channel, an upper beam (222) and a lower beam (223) forkedly extending from the contacting portion, a hook portion (224) formed at the distal end of the upper beam and secured with the insulative housing, and a second soldering portion (225) bent from the lower beam. An interspace (226) is defined between the upper beam and the lower beam. The first contacting portion protrudes into the receiving channel via the interspace.

主权项

1. An electrical connector for use with a plug, comprising:
an insulative housing defining a central receiving channel extending along a front-to-back direction with an insertion opening in a front side of the housing; two pairs of terminal passageways formed in the housing, each of said terminal passageways communicating transversely with the receiving channel and rearwardly with an exterior, each pair of terminal passageways including an outer terminal passageway and an inner terminal passageway; two pairs of contacts disposed in the two pairs of terminal passageways, respectively, and categorized with outer and inner contacts corresponding to the outer and inner terminal passageways, each of said outer and inner contacts assembled into a corresponding terminal passageway forwardly from a rear side of the housing, each of said outer and inner contacts defining a contacting section extending into the receiving channel for engagement with a plug and a mounting section exposed outside of the housing for mounting to a printed circuit board; wherein the contacting section of the inner contact and the contacting section of the corresponding outer contact are located at the same level while the contacting section of the inner contact is located in front of that of the corresponding outer contact, and a rear portion of the inner contact defines a space through which the contacting section of the corresponding outer contact extends for entering the receiving channel transversely; and wherein the inner contact defines an upper beam and a lower beam between which said space is formed, and the contacting section of the inner contact is inwardly offset from the upper beam and the lower beam along a transverse direction perpendicular to the front-to-back direction to enter into the receiving channel.
