Abstract: An adapter junction box is provided that consists of an upper and a lower shell, a base strip held in a base holder of the lower shell, a spring placed in each bushing segment on the top side of the base strip. A guard plate is put on the other end of the spring by a sleeve formed on the bottom side of the guard plate, so that the V-shaped heads of the sleeve of the guard plate are opposite to V-shaped guide heads of the bushing segment on the base strip, wherein the guard plate blocks the sockets. When a plug is correctly plugged into the sockets of the adapter junction box, the guard plate is turned at an angle by sliding the V-shaped heads on the V-shaped guide head as the guard plate is moved down by the pins of the plug, so that the path of the pins is cleared and the pins of the plug can engage the conducting strips. When a foreign object is plugged into one socket, the guard plate is pressed unevenly so that the guard plate is blocked and unable to turn to expose the conducting strips.

The terminal 1 is provided with a projecting portion 9 which allows the retainer to be moved to the primary locking position, by slipping off from a moving path of the detecting protrusion 57 toward the front side B of a terminal insertion direction, when the retainer is at the provisional locking position and the terminal is completely inserted at the normal position, and which prevents the retainer 28 to be moved to the primary locking position, by abutting against the detecting protrusion 57, when the terminal 1 is incompletely inserted before the normal locking position. The projecting portion 9 is provided with a detection hole 73 for detecting faulty insertion of the terminal.

Abstract: A connector includes a connector housing and a retainer, which can be moved from a temporarily secured position to a fully secured position in the connector housing. The retainer secures a terminal in the connector housing and cannot be erroneous moved into the fully secured position. The connector comprises a connector housing with a retainer insertion hole in a front surface, which reaches flexibly deformable spaces of lances provided in cavities. The retainer is inserted into the retainer insertion hole and held in a temporarily secured position. After a terminal member is inserted into the housing, the retainer is further pushed into the retainer insertion hole and moved to a fully secured position, which restricts flexible deformation of the lances. The direction that the retainer is moved into the temporarily secured position is generally at right angles to the direction the retainer is moved from the temporarily secured position to the fully secured position.

The cover has an end wall with the cord seal mounted therein such that the outer surface of the cord seal is at least substantially flush with respect to the exterior surface of the end wall of the cover to increase the difficulty of removing the cord seal from the opening in the end wall of the cover. In other words, the geometry of the exterior surface of the end wall of the cover blends with the geometry of the outer surface of the cord seal. The electrical connector can be either a male or a female electrical connector.

Abstract: A first terminal and a second terminal are provided, in which a winding terminal of a coil is connected to the first terminal and one end of the second terminal is positioned to overlap one end of the first terminal. One end of each terminal is connected by a soldered portion 12. One end of the first terminal is designed to serve as an engaging projection which is bent at a generally right angle to the longitudinal direction thereof. The engaging projection engages an engaging opening formed on one end of the second terminal. A constricted part is formed near the engaging opening to reduce heat escape. Because the first terminal and the second terminal are firmly secured to each other, a soldered portion is not affected by stress resulting from differences in the coefficients of thermal expansion of the terminals, the solder and the resin due to a change in application temperature and therefore, the reliability of the soldered connection is improved.
