Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shell and a housing holding structure in an I / O connector used for a communication device (for example, a portable telephone).

[0002]

2. Description of the Related Art A shell and housing holding structure in a conventional I / O connector will be described with reference to FIGS.

A conventional I / O connector 11 includes a number of contacts 12 aligned in one direction, an insulating housing 13 for holding the plurality of contacts 12, and a metal shell 14 in which the housing 13 is incorporated. Are configured as main components.

[0004] The housing 13 comprises a rectangular parallelepiped housing body 13A and a contact holding portion 13B.
A large number of contacts 12 are held at a constant pitch in the contact holding portion 13B.

[0005] The shell 14 is pressed on a single metal plate,
Processing such as cutting, cutting, and drilling is performed to form a square frame structure. Elastically deformable lance stops 14A, 14A are provided near both corners of the upper surface of the shell 14 on the housing insertion side.
Are provided by notches, respectively, and the lance stops 14A,
Each tip of 14 </ b> A protrudes toward the inside of the shell 14. Elastically deformable lance stops 14B, 14B are provided near both sides of the shell 14 near the mating connector fitting side.
Are provided by notches, respectively, and the lance stops 14B,
Each tip of 14B protrudes toward the inside of the shell 14. Locking holes 14C, 14C are opened near both corners on the mating connector fitting side of the upper surface of the shell 14, and a pair of protrusions of the mating connector are fitted into the locking holes 14C, 14C when the connectors are fitted. Inserted.

The housing 13 is connected to a contact holding portion 13B.
When the housing 13 is inserted into the shell 14 from the side, the projections (not shown) provided on both side surfaces of the contact holding portion 13B of the housing 13 respectively abut against the lance stops 14B, 14B. Can not be inserted deeply. At the same time, the housing 13
A pair of grooves (not shown) provided on the upper surface of the housing body 13A are locked by the lance stops 14A, 14A, respectively, so that the housing 13 cannot be pulled out of the shell 14.

[0007]

In the conventional I / O connector 11, the housing 13 is inserted into the shell 14 and fixed by the lance stops 14A, 14A, 14B, 14B. However, the housing 13 tends to rattle within the shell 14. If the dimension L of the housing body 13A in the insertion direction is long as shown in FIG. 6A, the housing 13 is assembled in a state parallel to the shell 14. However, when the dimension L is short as shown in FIG. 6B, the housing 13 is assembled in an inclined state with respect to the shell 14.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to improve the drawbacks of the prior art and to provide an I / O connector in which a housing is stably assembled at a predetermined position in a shell.

[0009]

According to the present invention, a plurality of contacts, an insulative housing (3) for holding the plurality of contacts, and a metal shell (4) incorporating the housing (3) are provided. ), U-shaped press-fit pieces (4C) are respectively formed on both side faces of the shell (4) by cutting and bending, and the U-shaped press-fit pieces (4C) are formed near both side faces of the housing (3). 4C) are formed respectively, and the U-shaped press-fit pieces (4) are formed on the both side surfaces of the shell (4).
C-shaped notches (4B) are respectively formed between the side where C) is formed and the opposite side, and the respective U-shaped notches (4B) are formed.
There is provided an I / O connector shell and housing holding structure in which a part on the mating side of the mating connector (5) of B) can be used as a locking portion (4D) with the mating connector (5). .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS I / O of an embodiment of the present invention
The connector will be described with reference to FIGS.

The I / O connector 1 of the present embodiment has a large number of contacts 2 aligned in one direction, an insulating housing 3 for holding the large number of contacts 2, and a shell in which the housing 3 is incorporated. 4 is configured as a main part.

The housing 3 comprises a rectangular parallelepiped housing main body 3A and a contact holding portion 3B. The contact holding portion 3B holds a large number of contacts 2 at a constant pitch. Grooves 3C, 3C into which U-shaped press-fit pieces 4C, 4C of the shell 4 described later are press-fitted are provided near both side surfaces of the housing main body 3A.

The shell 4 is formed into a square frame structure by subjecting a single metal plate to processing such as pressing, cutting, cutting, and drilling. In the vicinity of both corners on the housing insertion side of the upper surface of the shell 4, lance stops 4A, 4A are provided by cutting, respectively, and the tips of the lance stops 4A, 4A project toward the inside of the shell 4. As shown in FIG. 3D, U-shaped notches 4B, 4B are provided substantially at the centers of both side surfaces of the shell 3, respectively.
Each of the flat side surfaces in B is bent toward the inside of the shell 4 to form elastically deformable U-shaped press-fit pieces 4C, 4C. The mating side of the mating connector on both sides of the shell 4 (FIG. 3)
(D), the U-shaped notches 4B, 4B
The portion existing between them can be used as a locking portion 4D, 4D as a means for locking to the mating connector 5 as described later. Hold downs 4E, 4E are formed at lower portions of both side surfaces of the shell 4, respectively.

When the housing 3 is assembled into the shell 4, the elastically deformable U-shaped press-fitting pieces 4C, 4C of the shell 4 are pressed into the grooves 3C, 3C of the housing body 3A, respectively.
Therefore, the housing 3 is stably incorporated in the shell 4 and does not rattle.

As shown in FIG. 2, the plug hood 6
Are coated on both sides of the distal end of the mating connector 5.
Trapezoidal protrusions 5A, 5A, which can be retracted by springs, are provided respectively.

When the I / O connector 1 is fitted to the mating connector 5, the locking portions 4D of the shell 4
Each of the inclined cam surfaces A and 5A is pressed, and the protruding portions 5A and 5A are immersed into the mating connector 5. In the fitting completed state, the protruding portions 5A, 5A protrude again, and the locking portions 4D, 4D
Are locked on respective planes of the protruding portions 5A, 5A orthogonal to the fitting direction. Therefore, in this state, the I / O connector 1
From the mating connector 5 is prevented.

[0019]

As is apparent from the above description, according to the present invention, an elastically deformable U-shaped press-fitting piece integrally formed on both side surfaces of a metal shell is provided with both grooves of an insulating housing. Respectively, so that the housing is stably assembled at a predetermined position in the shell. Further, according to the present invention, the both locking portions formed on the opposite sides of the U-shaped press-fitting piece on both side surfaces of the shell can be used to prevent the I / O connector from being detached from the mating connector. .
