Coaxial connector

Abstract

The outer conductor is comprised of a first outer conductor ( 3 ) and a second outer conductor ( 4 ). The first outer conductor ( 3 ) and the second outer conductor ( 4 ) are connected to each other by attaching them to an insulating housing ( 1 ) and contacting the contact section ( 48 ) of the second outer conductor ( 4 ) to the first outer conductor ( 1 ). The backsides of the switching terminal ( 20 ) and the connecting terminal ( 21 ) are covered by a backside shielding section ( 43 ), and the lead section provided on the backside shielding section ( 43 ) is arranged between the lead section ( 20 B) of the switching terminal ( 20 ) and the lead section ( 21 B) of the connecting terminal ( 21 ).

Description

technical field [0001] The present invention relates to a coaxial connector with a switch mounted on information terminals such as mobile phones and used for their input / output units. Background technique [0002] A receptacle 80 of a conventional coaxial connector with a switch has an insulating case 81 as shown in FIG. 32 , and a fitting protrusion 82 is formed on the insulating case 81 . A terminal installation hole 83 is provided at the center of the fitting protrusion 82, and a connection terminal 84 and a switching terminal 85 having a contact portion 85a are installed in the terminal installation hole 83, and the disconnecting contact portion 84a of the connection terminal 84 contacts Switch terminal 85. An outer conductor (housing) 86 is attached to the insulating case 81 , and a cylindrical portion 87 of the outer conductor 86 covers the fitting protrusion 82 . [0003] The socket 80 constituted in this way is mounted on a printed circuit board (not shown), and th...

Problems solved by technology

[0013] The above-mentioned former conventional coaxial connector is on its receptacle 80, and the outer conductor 86 is installed on the insulating housing 81, covering the surroundings of the switching terminal 85 and the connecting terminal 84 that constitute the inner conductor, and the cylindrical portion 87 of the outer conductor 86 covers However, since there is no external conductor on the side of the lead wires 84a and 85a between the connection terminal 84 and the switching terminal 85, it lacks shielding and cannot obtain good high-frequency performance.

[0014] The above-mentioned latter conventional coaxial connector utilizes the cylindrical portion of the external conductor of the plug to be connected to the cylindrical portion 100a of the external conductor 100 of the socket 104 to connect the external conductor of the plug to the external conductor 100 of the socket 104, but The thickness of the cylindrical portion of the plug is relatively thin, and the strength of the cylindrical portion is weak, so the locking force is weak. When a strong external force is applied to the plug, the plug may fall off from the socket 104.

[0015] In addition, the back shield portion 100b of the outer conductor 100 is connected to the rear portion of the outer conductor body 100A via the bent portion 100c, and the back shield portion 100b is not placed on the bent portion 100c before the outer conductor 100 is mounted on the insulating case 102. Instead of bending, after the outer conductor 100 is mounted on the insulating case 102, the rear shield portion 100b is bent at the bending portion 100c, so the assembly of the socket 104 is troublesome.
