Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector housing that is made of synthetic resin and has an integrally molded lid, and that accommodates connection terminals in which electric wires are connected in an L-shape in a direction that intersects with the axial direction.

In a connector housing that accommodates a terminal fitting to which an electric wire is connected, the electric wire is particularly oriented in a direction substantially perpendicular to the direction intersecting the axial direction, that is, L
The above-mentioned housing of the terminal fitting with a shape connection is provided with a terminal accommodating chamber for accommodating the terminal fitting, and after the terminal fitting is inserted into the accommodating chamber, the lid body connected with a flexible hinge is closed, and the lid is closed. The connector housing is locked by locking a locking hole of a locking arm extending from the body into a locking protrusion provided on the front wall of the terminal accommodating chamber.

In the case of the above-mentioned connector housing, the hinge part has a thin wall thickness due to the requirement for flexibility, so it is easily damaged. Therefore, when a tensile load is applied to the electric wire, the lid body is separated from the hinge part. Otherwise, the terminal fittings may be exposed and damaged by external equipment.

The object of the present invention is to prevent the above-mentioned disadvantages that occur in the connector housing, and to provide a connector housing configured such that the lid does not fall off even if the hinge is damaged.

Next, embodiments of the present invention will be described with reference to the drawings.

In Figures 1 and 2, A is a connector housing made of synthetic resin, B is an electrical contact part _B1 and a wire connection part.
The electric wire connecting portion _B2 is a metal terminal fitting having a diameter B2, and the electric wire connecting portion _B2 connects the electric wire C in an L-shape in a direction perpendicular to the axial direction of the terminal fitting B by caulking the end of the electric wire C.

The connector housing A consists of a main body A ₁ and a lid body A ₂ , and the lid body A ₂ is connected to the rear side of the main body A ₁ by an integral hinge part 1 , and has a locking hole at the free end side on the opposite side of the hinge part 1 . A flexible locking piece 2 having a diameter 2a is provided to protrude toward the main body _A1 , and a locking protrusion 4 for the locking piece 2 is provided on the outer peripheral surface 3 of the connector main body _A1 .

On the outer peripheral surface 3 of the connector main body _A1 , a lock piece restraining plate 5 is provided behind the locking projection 4, with a lock piece insertion space S having a spacing _l1 between the lock piece restraining plate 5 and the outer peripheral surface 3. A guiding tapered portion 5a is formed inside the rear end of the lock piece restraining plate 5.

Now, the protrusion length of the locking protrusion 4 from the outer peripheral surface 3 is
l ₂ and the thickness of the lock piece is l ₃ , the relationship is l ₃ >l−l ₂ . Note that an outlet 7 for the electric wire from the terminal accommodating chamber 6 is formed at the rear end of the main body _A1 .

In the above configuration, the terminal fitting B to which the electric wire C is connected is inserted into the terminal housing chamber 6, and the lid body A ₂ is inserted into the main body A ₁
When the terminal fitting B is inserted into the terminal fitting B, it is completely pushed in even if it is inserted incompletely, and at this time, the locking piece 2 flexibly intrudes into the locking piece restraining plate 5, and the locking hole 2a engages with the locking protrusion 4. match.

In the embodiment shown in FIGS. 3 and 4, the lock restraining plate 5' is provided over a wide range, and a notch 5'a is formed in a portion corresponding to the locking projection 4.

In the embodiment shown in FIGS. 5 and 6, the lock restraining plate 5'' is constituted by the inner wall of the wire outlet trough D which is continuous with the wire outlet 7. In the embodiment shown in FIGS.

Since the present invention is constructed as described above,
Since the hinge part looks like it is damaged,
The restraint plate maintains the engagement between the lock piece and the locking protrusion, thereby preventing the lid from falling off.
