JPH065161U - Multi-pole plug - Google Patents

Abstract

(57) [Summary] [Purpose] The purpose is to obtain a multipolar plug. [Structure] A plug body 2 includes a first insulating collar 6 positioned between a tip 4 and a first ring 5, and a second insulating collar 8 positioned between the first ring 5 and a second ring 7. , A third insulating collar 10 positioned between the second ring 7 and the sleeve 9, and the first insulating collar 6, the second insulating collar 8 and the third insulating collar 10 are molded from the same synthetic resin. At the same time, the fourth insulating collar C in which the terminal 3 was press-fitted was fitted and fixed to the sleeve 9.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a multi-pole plug used in a weak electric relation such as an audio device.

[0002]

[Prior art]

 As a conventional technique, Japanese Utility Model Laid-Open No. 3-48882 can be cited.

[0003]

[Problems to be solved by the device]

 In the above-mentioned prior art, it was a 4-pole plug, and its use range was narrow and limited. The present invention has been made in view of these points, and aims to widen its application and use range, and actually makes it possible to use an 8-pole plug.

[0004]

[Means for Solving the Problems]

 A first insulating collar positioned between the chip and the first ring; a second insulating collar positioned between the first ring and the second ring; and a second ring and a sleeve. A first insulating color, a second insulating collar, and a third insulating collar, which are made up of a third insulating collar positioned between them, are injected and solidified with the same synthetic resin, and a metal terminal is pressed into the sleeve. No. 4 insulation collar is press-fitted and fixed.

[0005]

【Example】

 Reference numeral 1 denotes a multipolar plug body, which is mainly constructed by press-fitting and fixing a fourth insulating collar C into which a metal terminal 3 has been press-fitted into a plug body 2. The plug body 2 described above includes a first insulating collar 6 positioned between a chip 4 as a conductor and a first ring 5 and a first insulating collar 6 positioned between the first ring 5 and a second ring 7. It comprises two insulating collars 8 and a third insulating collar 10 positioned between the second ring 7 and the sleeve 9, said first insulating collar 6, second insulating collar 8 and third insulating collar 10 Are solidified by injection with the same synthetic resin.

A knurl 11 is cut in a part of the outer peripheral portion of the sleeve 9 described above, and the press-fitting fitting hole portion 12 of the fourth insulating collar C in which the terminal 3 has been press-fitted is fitted integrally. is there. Reference numeral 13 is a slit groove hole provided in the fourth insulating collar C for press-fitting the terminal 3, and in this embodiment, two slit groove holes are provided, but four or six slit holes may be provided. Reference numerals 14 and 15 denote cut-and-raised pieces formed on the terminal 3.

Next, the order of assembling the product of the present invention will be described. The press-fitting fitting hole portion 12 of the fourth insulating collar C in which the terminal 3 is press-fitted into the slit groove hole 13 is fitted and fixed to the sleeve 9 in which the knurl 11 of the plug body 2 formed by resin molding is cut. As a result, the multipolar plug body 1 is completed.

[0008]

[Effect of device]

 Since the fourth insulating collar C in which the terminal was press-fitted was fitted and fixed to the synthetic resin molded plug body 2, a multipolar plug body could be constructed, and its application range was expanded. Further, since the plug body 2 and the fourth insulating collar C are fixed type, there is no contact failure and the stability of the current characteristic is improved as compared with the conventional insertion rotary type.
