Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a connector housing for a connector used for connecting wire harnesses and the like.

``Prior Art'' A flexible arm provided between the passages of the storage chamber for the electrical connector is bent outward by the electrical connector when the electrical connector is being inserted, and the arm is bent outward when the electrical connector is being inserted. When it reaches a predetermined position in the chamber, it returns and engages the shoulder of the electrical connector to prevent the electrical connector from retreating.
Due to the miniaturization of the connector main body, the flexible arm also tends to be made thinner, and the flexible arm alone may not be able to prevent the electrical connector from retreating. Therefore, in these connectors, a connector was developed in which the flexible arm functions as a first locking means and a second locking means is provided. However, when this second locking means is positioned in the same manner as the first locking means, the insertion force of the electrical connector is doubled because it requires a force to penetrate the bending shape of the flexible arm. There is.

For this reason, the second locking means is normally located away from the insertion path of the electrical connector, and when the electric connector is housed in a predetermined position, the first locking means is engaged with it. When assembled, a spacer was required to engage the electrical connector.

In the connector housing as described above, walls for supporting the electrical connectors in the terminal accommodating chamber protrude from both sides between the terminal accommodating chamber and the cavity.

"Problems to be Solved by the Invention" When molding with a mold, molding cannot be performed unless the distance between the side walls 7 and 7' is wide. However, if it is made wider, the protruding portion that is latched to the pedestal will become smaller, and there is a possibility that the terminal will fall off.

(Figure 4) "Means for solving the problems" In order to solve both problems, a pair of side walls 7,
It was decided to gradually widen the interval 7' toward the cavity 6. (Fig. 3) "Operation" After inserting the electrical connector 1 into the accommodation chamber 5, inserting the spacer 4 into the second locking means causes the flexible arms to bend upward or downward, respectively, thereby establishing the electrical connection. It is attached to the child's shoulder. At this time, the distance between the pair of side walls is gradually widened toward the cavity 6.

"Example" The terminal accommodating chamber has a first locking part and a second locking part,
The first locking portion forms a locking arm 2 extending from the central upper surface of the housing chamber 5 from the terminal receiving port toward the mating fitting port, and the arm 2 is designed to prevent the electrical connector from being inserted when the terminal is inserted. 1 is in the process of being inserted, it is pushed by the electrical connector 1 and bends outward, causing the electrical connector 1 to bend outward.
When it reaches a predetermined position in the storage chamber 5, it returns and engages with the shoulder of the electrical connector to prevent the electrical connector from retreating.

On the other hand, the second locking part has a second locking arm 3 in the same direction as the first locking arm 2 on the side opposite to the first locking part.
is formed into two forks, and a cavity 6 is provided inside both of the locking arms. By inserting the spacer 4 into this gap 6, the locking arm 3 opens outward.
It locks with the electrical connector 1. In the connector housing as described above, when the second locking arm 3 enters the terminal accommodating chamber 5, the distance between the pair of side walls 7, 7' gradually widens toward the cavity 6.

"Effects" By gradually expanding the pair of side walls toward the gap, molding becomes easier, and the part that holds the terminal can be made wider than before, preventing the terminal from falling. be able to.
