DETAILED DESCRIPTION OF THE INVENTION The present invention is an improvement in the locking means for the terminal fittings in the terminal accommodating chambers of the connector housing.

従来の端子収容室における端子金具の係止手段は第1図
のような構成を有する。
A conventional locking means for a terminal fitting in a terminal accommodating chamber has a structure as shown in FIG.

That is, A is a connector housing, and when the terminal metal fitting B is inserted into the terminal housing chamber a, the electrical contact portion B1 formed at the front of the board portion abuts against the stopper wall C, preventing it from being pulled out to the front. At the same time, the locking protrusion e at the tip of the flexible arm d engages with the rear end of the electrical contact part B1, and the accommodation chamber a is prevented from coming out.
The device was pressed against the bottom wall of the device to prevent it from wobbling or coming out backwards.

なお、B2は電線接続部、Wは電線である。In addition, B2 is an electric wire connection part, and W is an electric wire.

しかし、上記構成の場合、上記可撓アームdは何ら保護

Therefore, when tension is applied to the electric wire W, the flexible arm d bends or deforms, causing fatigue, and in severe cases, cracks occur in the locking protrusion e, impairing the function of the flexible arm d. However, there was a drawback that the terminal fitting B could easily be removed, and furthermore, once the terminal fitting B was inserted, it could not be removed without using a special jig.

The present invention was developed with the above-mentioned points in mind. By installing a protective cover to protect the flexible arm, it is possible to prevent deformation and damage to the flexible arm, and even if the flexible arm is damaged, the terminal fitting can be prevented from coming out. Another object of the present invention is to provide a connector housing in which the terminal fitting itself can be attached and detached extremely easily by removing the protective cover.

First, when the terminal fitting B is inserted from the lower open end of the terminal accommodating chamber 3, the tip of the electrical contact portion B1 comes into contact with the locking protrusion 10, as shown in FIG. 3A, but the tapered surface 10'
This causes the flexible arm 9 to bend outward and smoothly enter.

As a result, since the flexible arm 9 is supported by the protective cover 11, it will not bend or deform at all even if tension is applied to the electric wire W, and the stress exerted on the locking protrusion 10 will be transferred to the spacer 14. Since it is dispersed and is less prone to damage due to cracks as in the conventional case, it can always be locked in a stable state.

また、張力が強過ぎて係止突起10に亀裂が生じて破損
