DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector, and more particularly to a hood mounting structure in a connector in which a hood is mounted outside an insulator or a shell.

[0002]

2. Description of the Related Art FIG. 3 is a perspective view showing a disassembled state of a conventional hooded connector. Reference numeral 60 denotes an insulator of the connector body, 61 denotes a shell, 63 denotes a shield member, and 66 denotes a rear end side of the connector body. Is a cable that is connected and fixed. As is clear from this figure, hoods 5A and 5B are attached to the outermost side of the connector. The hood of the type shown in FIG. 3 is divided into an upper hood 5A and a lower hood 5B, has a groove for forming a cable lead-out hole on the rear end side, and has a cable 66 connected and fixed at the rear end. With the main body sandwiched from above and below, it is attached so as to engage with both ends of the contact in the pitch direction.

[0003]

In a hood of the type described above in which both ends of a hood of the type described above are engaged with and attached to a connector body (shell, insulator, etc.), the number of contact pins is small, and In the case of short dimensions, the hood can be properly attached to the connector body only by the engagement portions on both sides.

However, due to the high performance of the equipment,
As the number of pins increases, the dimension of the connector in the pitch direction also increases. In this case, however, the hood is engaged only at both ends, and as a result, the hood is easily bent near the center in the pitch direction. Thus, when the hood is bent,
A gap is formed between the connector body and the hood, and the hood is easily disengaged.

The present invention has been proposed in view of the above-mentioned problems of the prior art, and has as its object to provide a connector in which the hood does not bend on the upper and lower surfaces of the connector.

[0006]

According to the present invention, a connector body having a contact pitch direction as a longitudinal direction and a shell provided on a front fitting side, and the connector body is connected to upper and lower sides from above and below. And a hood attached to the connector body by engaging the upper and lower hoods at both ends in the longitudinal direction with the hood sandwiched between two hoods, wherein the shell extends in the longitudinal direction above and below the hood. At a predetermined position of the rear end edge, the outer hood is provided with a folded portion folded on a U-turn toward the distal end side, and the upper and lower hoods extend on the inner surface thereof in the longitudinal direction and extend in the longitudinal direction. A connector characterized by having an engagement groove engaged with the folded portion of (1).

Further, according to the present invention, the connector main body is connected and fixed to a cable at a rear end side, and the hood is provided with a cable lead-out hole at a rear end portion. Can obtain a connector characterized by being a groove that is opened rearward.

[0008]

According to the present invention having the above-described structure, since the engaging portion between the hood and the connector main body is formed on the longitudinal side of the connector, the hood attached to the connector main body does not bend, and the connector main body is not deformed. There is no gap between the hood and the hood.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view showing an essential part of an embodiment of the present invention, and FIG. 2 is a side sectional view.

As shown in FIGS. 1 and 2, a longitudinal direction (contact pitch direction) of a rear end portion of the shell 13 provided on the fitting portion side of the connector 1 (the side opposite to the fitting connection side of the connector). At a substantially central portion (including the central portion), there is formed a folded portion 15 which is folded in a U-turn toward the front end side.

On the other hand, at the center of the inner surface of the hood 3, there is formed an engaging portion 30 for engaging with the folded portion 15. As shown in FIG. 2, the engaging portion 30 has an engaging groove 31 extending in the longitudinal direction. In addition,
Although only the lower hood 3 is shown in FIG. 1 and the upper hood is omitted, a similar hood is attached to the upper side of the connector 1 as shown in FIG.
In the present invention, the material of the hood is not particularly limited, and is formed of a conventionally used material. The form and structure of the components other than the engaging portion 30 of the hood 3 are not limited at all, and are configured, for example, in the same manner as the conventional example shown in FIG.

Next, the assembly of the hood 3 to the connector body will be described.

In the illustrated example, the folded portion 15 of the shell is folded forward, and the engaging groove 31 of the hood is a groove opened rearward. Alternatively, the hood 3 (toward the lower side) is addressed, and the hood 3 is tilted and moved in the direction of arrow A so that the engagement portion 30
Is engaged with the folded portion 15 of the shell 13, and thereafter, the hood 3 is rotated in the direction of arrow B. Thereafter, the same operation is repeated for the other lower (or upper) hood 3 to assemble the hood 3 to the connector main body 1.

In the above embodiment, the folded portion 15 to be engaged with the engaging groove 31 formed in the hood is formed only in the shell 13, but the present invention is not limited to this.
It goes without saying that a mating member that engages with the engaging groove 31 of the hood may be formed in another portion such as the insulator or the shield member of the connector.

Further, in the above-described embodiment, the engagement holding portions of the hood are provided at the longitudinally central portions of the upper and lower surfaces of the shell.
Although a plurality of locations are provided, the present invention is not limited to this, and a plurality of locations may be provided on the upper and lower surfaces, respectively. Providing a plurality of locations in this manner increases the degree of adhesion between the hood and the connector body, and effectively prevents the hood from bending.

Further, in the present invention, the engagement portion between the hood and the connector main body (shell, insulator, etc.) may be formed continuously over the entire length in the longitudinal direction.

In the present invention, by simply replacing the conventional shell and hood with those of the present invention, other parts can be used as they are, and the hood can be mounted at low cost without bending.

[0019]

As described above, according to the present invention, the engaging portion between the hood and the connector main body is formed not on both ends of the connector but on the upper and lower surfaces, which are the long sides, so that the hood can be engaged. Since it is fixed and held on both sides of the joint portion and the connector main body, bending on the longitudinal side does not occur. As a result, no gap is formed between the connector body and the hood, and stable hood engagement can be obtained.
