Abstract

A connector jack including a molded retainer, a conducting pin centrally located within the molded retainer, and a resilient clamping element. The molded retainer is a cylindrical body having a central recess at its front end for receiving an annular prong of a plug, two slots at its rear end thereof for receiving the resilient element, and a central stepped recess at its rear end and a perforation for receiving the conducting pin. The resilient clamping element has a conducting leg, a fixing leg and a T-shaped stem which connects the two legs. The two legs are insertable into the slots respectively. The conducting leg further includes a semicircular-shaped conducting end at its inner side which projects over the slot into the central recess.

Claims

1. A connector jack comprising:

a molded retainer (10) having a cylindrical body including a central recess (11) at a front end thereof for receiving an annular prong of a plug, two slots (12) at a rear end thereof, a central stepped recess (13) at the rear end thereof, and a perforation (14) formed on a base of said stepped recess (13);

a conducting pin (20) centrally located within said molded retainer (10), said conducting pin (20) including a pin body (21), two conducting arms (22) formed in parallel with said pin body (21), and a pin-neck (23) which connects the two conducting arms (22) to said pin body (21), said pin-neck (23) having a stepped profile, said conducting pin (20) being insertable into said central stepped recess (13) with said pin body (21) passing through said perforation (14) and being retained in said central recess (11), said pin-neck (23) being retained in said stepped recess (33); and

a resilient clamping element (30) including a conducting leg (31) and a fixing leg (32) and a T-shaped stem (34) which connects said conducting leg (31) and said fixing leg (32), said conducting leg (31) and said fixing leg (32) being respectively insertable into said slots (12) of said molded retainer (10), said conducting leg (31) further including a semicircular-shaped conducting end (311) at an inner side thereof, said semicircular-shaped conducting end (311) projecting over said slot (12) into said central recess (11).

2. A connector jack as claimed in claim 1, wherein a sidewall of said molded retainer (10) at a position corresponding to each slot (12) is formed with a protrusion (15).

3. A connector jack as claimed in claim 2, wherein said conducting leg (31) and said fixing leg (32) are formed with respective cutout (33) for engagement with said protrusions (15).
