<p>PROBLEM TO BE SOLVED: To provide a jack which has a compact size and can increase a rating current of a contact.SOLUTION: A jack 10 is connected to a plug 8 consisting of an inner tube terminal 81, an insulation cylinder 82 and an outer tube terminal 83. The jack 10 has a housing 1, a first contact 2 and a second contact 3. The housing 1 has a plug housing chamber 11 in which a plug insertion port 1a is opened and which receives the plug 8. The first contact 2 has a thin shaft-shaped first contact part 22 capable of being connected to the inner tube terminal 81. The second contact 3 has a second contact part 32 having an elastic bent piece 33 arranged so as to face to the first contact part 22 and contacting with the outer tube terminal 83. The second contact part 32 is arranged along a wide surface of an inner wall of the housing 1, and has a heat radiation part 34 for sequentially transmitting heat to a fixed edge of the elastic bent piece 33. The jack 10 transmits heat caused by increased current flowing in the second contact 3, to the heat radiation part 34.</p> |
