Description

  The present invention relates to a transceiver module, which has a function of transmitting and receiving data, and relates to a transceiver module that is mounted on an information processing apparatus such as a server apparatus and is in use.

  One type of LAN (Local Area Network) is an Ethernet (Ethernet (registered trademark)) LAN which is a bus type LAN. The Ethernet LAN is constructed by installing a server device having a function of transmitting and receiving data and connecting a signal transmission path thereto. This system such as a LAN is as long as several tens km when the data transmission distance is long, and as short as about 10 m when the distance is short, and the scale varies depending on the user. Therefore, a plurality of types of transceiver modules, which are modules having functions for transmitting and receiving data, are prepared according to the communication distance so that the user's needs can be flexibly handled. It is configured to have a plurality of mounting portions and assembled by mounting a desired transceiver module on the mounting portion. Further, when there is a change in the data transmission distance, the transceiver module is removed from the mounting portion, and another transceiver module is mounted.

  The transceiver module has an external connection connector, a pull sleeve surrounding the external connection connector, and a locking claw on the end side. When the operator pulls the pull sleeve in the mounted state, the locking claw is retracted so as to be recessed, the lock is released, and the transceiver module is pulled out from the server device.

  Conventionally, an example of the pull sleeve has a configuration in which an inverted U-shaped upper sleeve and a U-shaped lower sleeve are both made of die-cast and screwed.

  As another example of the pull sleeve, there is a configuration in which both the upper sleeve and the lower sleeve are made of synthetic resin, and the lower sleeve and the upper sleeve are fixed by press-fitting.

  However, the die-cast pull sleeve was not slidable and the operation feel was not good.

  In the case of the synthetic resin pull sleeve, the slidability is improved compared to the die-cast pull sleeve, but the lower sleeve may come off from the upper sleeve over the years of use. .

  In particular, if the pull sleeve is made of a synthetic resin whose surface is slippery in order to improve the slidability, the lower sleeve is likely to be detached from the upper sleeve. Further, if the surface is made of a synthetic resin having a slippery property, there is a problem that sufficient adhesive force cannot be obtained even if an adhesive is used. In addition, when considering mass production in a factory, it is necessary to manage the amount of adhesive, temperature, etc. in order to perform the bonding process, which is troublesome.

  An object of the present invention is to provide a transceiver module made in view of the above points.

In order to solve the above problems, the present invention has an external connection connector on the front side of the housing, and has a pull sleeve provided so as to surround the external connection connector, and pulls the pull sleeve. In the transceiver module that is pulled out from the mounting part by operating,
The pull sleeve is a combination of an upper sleeve and a lower sleeve, both of which are made of synthetic resin, and is sandwiched and fixed by an inserted clip.
The clip has a plate-like shape, and includes a vertically oriented main body, upper and lower arms extending from both ends of the main body, and a hook at the tip. Is a shape having a notch recess,
Each of the upper sleeve and the lower sleeve has a slit into which the clip is inserted, and has a protrusion that fits into the notch recess inside the slit,
The clip is inserted into the slit, the hook portion is locked and attached, and the protruding portion of the upper sleeve and the protruding portion of the lower sleeve are fitted in the notch recess. It is characterized by that.

  According to the present invention, the notch recess formed in the vertically oriented main body is configured to fit between the protrusion of the upper sleeve and the protrusion of the lower sleeve, so that the upper sleeve and the lower sleeve Can be fixed sufficiently firmly.

  Next, an embodiment of the present invention will be described.
