The optical plug receptacle used in the above-mentioned wiring device for optical fiber comprises a plug connection portion into which an optical fiber plug attached to an optical fiber cable wired to the inside of a building is inserted and connected. The optical plug receptacle optically connects an optical fiber plug inserted through a plug connection hole from the outer surface side of a building and the optical fiber plug connected to the plug connection portion. However, the optical plug receptacle is attached to the rear side of the rotatable retainer such that, when the plug receptacle main body is attached to a attaching surface in the normal direction, the plug connection hole faces the downward direction (that is, the direction of insertion into the plug connection hole is nearly in parallel with the front surface of the plug receptacle main body). As a result, when the optical fiber plug is inserted into and connected to the plug connection portion of the optical plug receptacle, this operation is obstructed by the transverse wall of the plug receptacle main body, which it is impossible to carry out a connection work of the optical fiber plug, thereby leads to deterioration in the performance of construction work. 1.

The present invention relates to devices and methods for use in orthopedic spine surgery. In particular, the present invention relates to a bone plate system that provides a low profile anterior vertebral body plate and at least one spike fixation element, the system being used for fixation and stabilization of the spine, the spike fixation elements being located proximate to at least one end of the plate to provide a secure attachment to the underlying bone.
2. Background Art
Disease, the effects of aging, or physical trauma resulting in damage to the spine has been treated in many instances by fixation or stabilization of the effected vertebra. The use of plates and screws for fixation and stabilization of the cervical vertebra has been widely accepted as a reliable practice and has proven to be highly successful clinically.
The various plates, which are attached to the anterior vertebral bodies of the spinal column by bone screws have some common features such as relatively planar body profiles that define multiple holes or slots through which the screws fit and are threaded into the bone. A common problem with plates affixed to bone using conventional bone screw attachments is the unintentional backing out of
the plug receptacle main body; pressing mean for normally press the rotatable retainer toward the front side; retain mean for retaining the received state; and a start - up mechanism for projecting the optical chew receptacle toward the front side when the maintenance of the retain means is released. 
 The ocular fireplug receptacle used in the above - mention wiring device for optical fiber consist a plug connection portion into which an ocular fiber plug attached to an optical roughage cable wired to the inside of a building is inserted and connected. The ocular plug receptacle optically connects an optical fiber plug inserted through a plug connection hole from the outer surface side of a building and the optical fiber plug connected to the chew connection portion. However, the ocular spark plug receptacle is attached to the rear side of the rotatable retainer such that, when the ballyhoo receptacle chief body is attached to a impound surface in the normal direction, the plug connection trap faces the downward direction (that is, the direction of interpolation into the plug joining fix is nearly in parallel with the front surface of the plug receptacle chief body). As a result, when the optical roughage plug is inserted into and connected to the plug joining portion of the ocular plug receptacle, this operation is obstruct by the transverse rampart of the plug receptacle main body, which it is impossible to carry out a joining work of the optical fiber plug, thereby leads to deterioration in the operation of construction work. 1.
