摘要： The present invention relates to an electrical connector with a locking mechanism which is to be locked to a counter electrical connector by insertedly connecting the connector to the counter electrical connector and then conducting a given rotating operation, and in which only a given rotation operation is required for enabling a locking state to be naturally canceled by a spring force. According to the present invention, irrespective of whether the electrical connector has a single pole or plural poles, the connectors can be connected and locked to each other without requiring an adjustment of a lock ring in the peripheral direction, only by determining the fitting position. In the electrical connector with a locking mechanism of the present invention, a lock ring at the initial position is positioned by fitting between a protruding portion disposed on a fitting portion, and a recess portion disposed in a lock ring fitted onto the fitting portion. When the lock ring is positioned by the fitting of the protruding portion and the recess portion, a fitting mechanism conducts the positioning operation and a connector is insertedly connected to the counter connector. Then, an outward projection of the counter electrical connector is fitted into a slot of the lock ring. The lock ring is always urged in the advancing direction by a spring member.
摘要翻译：本发明涉及具有锁定机构的电连接器，该锁定机构通过将连接器插入相对电连接器并且然后进行给定的旋转操作而被锁定到逆电连接器，并且其中仅需要给定的旋转操作以使得能够通过弹簧力自然地取消锁定状态。根据本发明，无论电连接器是单极还是多极，只要确定安装位置，连接器就可以彼此连接并锁定，而不需要在周向方向上调整锁环。在具有本发明的锁定机构的电连接器中，初始位置处的锁定环通过配合在设置在装配部分上的突出部分和设置在安装在装配部分上的锁定环中的凹部之间而定位。当通过突出部分和凹部的配合来定位锁定环时，配合机构进行定位操作，并且连接器插入连接到对位连接器。然后，逆电连接器的向外突出部嵌入锁环的槽中。锁定环总是通过弹簧构件在前进方向上被推动。

摘要： In a plug, an insulating body is disposed in a cylindrical metallic shield cover, a plurality of signal contacts and two power supply contacts are held by the insulating body axially thereof and are separated by a square-sectioned partition wall extending from the insulating body. The front end face of the partition wall lies forwardly of the tips of the contacts.In a socket to which the plug is put, a plurality of signal contacts and two power supply contacts are held by an insulating body axially thereof. A cylindrical metallic member is mounted in the body in a manner to surround the contacts. In the cylindrical member a columnar key extends forwardly from the insulating body on the center axis of the cylindrical member. The power supply contacts are housed in slots made in said columnar key and extending rearwardly from its front end face. Support plates extend from the insulating body on both sides of the columnar key in opposed but spaced relation thereto, and the signal contacts are housed in housing grooves cut in the support plates on one sides thereof and extending axially thereof. The tips of the power supply contacts and the signal contacts lie short of the front end portions of the columnar key and the support plates.

摘要： A columnar key is formed integrally with a socket body of an insulating material attached to the back of a cylindrical metal member of a socket and extends in the cylindrical member axially thereof. The socket body had contact support plates extending axially therefromm in the cylindrical member so that they extend over and under the columnar key, respectively. The cylindrical member has a plug guide portion for guiding a cylindrical metal shield cover of the mating plug to the position where the front end face of the plug body abuts against the front end face of the columnar key while holding the center axis of the shield cover of the plug in alignment with the center axis of the cylindrical member of the socket after the cylindrical metal shield cover of the plug is inserted into the cylindrical member of the socket. By turning the plug about its axis to a specified rotational angular position after the front end face of the plug body abuts against the front end face of the columnar key, the columnar key is fitted into a key hole made in the plug body, permitting further insertion of the plug into the socket.
