Description

  The present invention relates to a pin jack used together with a pair of pin plugs for transmitting audio signals of audio equipment and other various signals and for connecting power supply paths to various electric or electronic equipment.

  This type of pin jack includes a housing in which a cylindrical bush portion is projected, a contact member inserted from the rear portion into the housing, and a grounding metal fitting that is externally provided on the front side of the housing including the bush portion. The terminal portions extending from the ground metal fitting and the contact member are configured to protrude rearward or laterally of the housing in relation to the connection object. Needless to say, the contact member is positioned so that the contact portion contacts the pin portion of the plug inserted from the plug insertion hole of the bush portion.

  Since such a pin jack is to attach and attach a contact member to the housing from its rear part, the rear part of the housing is open, and usually the opening part from the plug insertion hole of the bush part to the rear part. Up to the communication state. Therefore, when this type of pin jack is used as, for example, a connection means for transmitting and receiving an audio signal arranged in a speaker box of an acoustic device, acoustic vibration radiated from the speaker leaks through the pin jack. Cause serious problems. In addition, there is a risk that external dust may enter the inside of the device regardless of which device is used.

  For example, the pin jacks of Patent Documents 1, 2, 3, and 4 are generally configured as described above, and in the case where they are arranged in the speaker box as described above to be used for sending and receiving audio signals, There is such a problem of leakage of acoustic vibration, and even if it is not such usage, it is inconvenient when used in a device in which the entry of dust is extremely problematic.

  Therefore, in order to close the opening at the rear part of the housing as described above, means such as applying a bond to the opening or covering the pin jack itself with some case is known. There is a problem of increasing the number of assembling steps or the number of parts when attaching to the device.

  In view of this, it is conceivable to previously close the opening formed in the rear portion of the housing with a cover member. Although the pin jack of Patent Document 5 is not configured for the above-described purpose, a configuration including a main body (housing) and a cover disposed on the back side thereof has been proposed. There have been proposed a type in which the cover part is integrally formed through a main body part and a thin hinge part and a type in which the cover part is individually molded and combined later. According to this, although the problem which arises when the front and back of the said pin jack communicate is solved, in any case, there exists a difficulty that components, such as a cover part which is complicated and large in size, increase.
