Socket

Abstract

The invention relates to a socket, which can receive a door openable with a contact inserted into the two contact spigots (5a) freely plugging a socket port (5) within a machine body. On the door, a pivot part is formed within a plane which is basically orthogonal with the sliding movement direction, relative to the upward and downward movement of a central frame (50), capable of flexibly supporting. A limiting bar is formed on inner lateral face of the front wall of a cover (3), when the limiting bar is inclined with the pivot part as the pivot on the door, the limiting bar contacts an end of the door which is close to the inner lateral side of the front wall of a machine body (1), limiting the sliding movement of the door, moreover, the protruding amount of the limiting bar is preset to be the size which is more than the maximum value of the allowance size range of the spacing between the part of the door contacted by the door and the inner side of the front wall of the cover (3) under the condition that the door is inclined with the pivot part as the pivot. Therefore, even when the size of the parts is deviated, the door can be prevented to be opened when foreign matters, such as pins, are inserted.

Description

technical field [0001] The present invention relates to sockets. Background technique [0002] Conventionally, there has been provided a socket in which a blade receiving member for connecting the blades inserted from the contact sockets is accommodated inside a body having a socket opening formed by two contact sockets inserted into the blades of the plug on the front, And a door that can freely open and close the two contact sockets and is opened by a plug inserted into the contact sockets. The door is slidably maintained in a direction parallel to the front of the body, and is pushed by a spring in a direction to close the contact socket, thereby blocking the contact socket in a state where the insert piece is not inserted in the contact socket. In addition, when the door is evenly pushed by the inserts inserted from the two contact sockets, the pressure of the inserts is converted into a force that makes the inserts slide and move, so that the door can overcome the elas...

AI Technical Summary

Problems solved by technology

In the state where the three blade sockets constituting the three-pole socket are blocked by the door, because the outer edge position of the door that blocks the two blade sockets inserted into the blade of the voltage pole is in the plane parallel to the front of the body, It is in roughly the same position as the inner wall surface of the voltage pole insert socket. Therefore, due to the dimensional deviation of the parts, it is easy for foreign matter to enter between the outer edge of the door and the inner wall surface of the contact socket. The foreign object is inserted obliquely between the outer edge of the door and the inner wall of the contact socket to pry the door, and it is possible to open the door
