Description

[Detailed Description of the Invention] [Technical Field] The present invention provides electrical connection between a contact spring installed between a modular jack and a modular plug and disposed within the modular jack and a contactor exposed on the modular plug. This relates to a modular adapter that connects to the.

[Background technology] In general, a modular plug that is removably inserted into the plug insertion slot of a modular jack has a distance from the plug body that increases from one end of the plug body on the modular jack side to the other end in the insertion direction. It is equipped with an operating lever that protrudes so as to widen it.

A retaining portion is formed on the operating lever, and when the lever is inserted into the modular jack, this engaging portion engages with the opening periphery of the plug insertion opening, so that it is held in a mononilar gloss. Further, the engaged state is released by applying an external force to bring the tip of the operating lever closer to the plug body.

By the way, when such a modular plug is attached to a modular jack, there is a problem in that the amount of protrusion of the operating lever from the monocular gloss is generally small, making it difficult to operate the operating lever. In the case of an inserted embedded type module error jack, the operation lever is on the lower side, making it difficult to perform the -/II operation. Furthermore, since the operating lever is located on the lower side and its position is difficult to find, the engaging part may be damaged if you try to forcefully remove it.

It is adapted to contact the contact spring of the modular jack.

Cover 1b plug ff! ! 2 has a cover lb on the outer surface from one end opposite to the glossy part 3 to the other end.
A release lever 22 is provided that protrudes to increase the distance from the release lever 22. The release lever 22 has elasticity, and if an external force is applied to bring the tip of the release lever 22 closer to the cover 25 and then the external force is removed, the tip of the release lever 22 will return to its original position. It has become. The release lever 22 has a base portion wider than the tip ms, and has a shape in which engagement steps fgJ23 are formed on both side edges of the intermediate portion. That is, when the plug part 2 is inserted into the plug insertion opening of the modular jack, the engagement step part 23 engages with the opening periphery of the plug insertion opening, and the plug part 2 is held in the monoerror jack. When pulling out the plug portion 2 from the mono error jack, it is sufficient to apply an external force to the release lever 22 so as to bring the tip of the release lever 22 closer to the cover 1b.

In the jack part 3, a plug insertion opening 31 is opened on one side of the housing 1 opposite to the plug part 2, and the modular plug 10 can be inserted therein. That is, the plug insertion opening 31 is formed in the same shape as the plug insertion opening of the mononylon gloss, and when the modular plug 1o is inserted into this plug insertion opening 31, the modular
The operating lever 12 of the plug 10 engages with the opening periphery of the plug insertion port 31 to hold the modular plug 1o. The contact spring portion 21b of the connecting member 21 faces inside the plug insertion opening 31. The contact spring portion 21b is the third
