BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable connector, and more particularly to a method for preventing the resin of the hood from adversely affecting the contact performance of a contact when the hood is formed by mold-in after the cable connection. It is about technology.

[0002]

2. Description of the Related Art In a conventional cable connector,
As shown in FIG. 5, the contact 10 has a contact portion 11 curved at the tip and a press-fit portion 14 formed wide.
The contact 10 is press-fitted into receiving holes 21 and 22 formed in the insulator 20. Of the receiving holes, 21 is a portion for receiving the press-fit portion 14 of the contact 10 in a holding state, and 22 is a contact portion 11.
Is a part for inserting and housing.

The receiving hole 22 formed in the insulator 20 for inserting the contact portion 11 of the contact 10 is kept open after the contact portion 11 passes. Therefore, in order to make a connector having such a configuration with a hood, when performing mold-in, it is necessary to eliminate the gap between the back shell to be incorporated after connection with the cable. For this reason, a resin is applied to the gap to fill the gap, that is, so-called potting is performed so that the mold material does not enter from the gap at the time of mold-in.

[0004]

[Problems to be Solved by the Invention] However, the work of potting in the gap as described above tends to be a manual work, which not only causes an increase in manufacturing cost but also causes a variation in quality.

Therefore, a technical problem of the present invention is to provide a connector for a cable with a hood, which does not require a potting operation, can reduce the manufacturing cost, and has a small variation in quality.

[0006]

SUMMARY OF THE INVENTION The cable connector of the present invention is provided.
The contactor includes a contact integrally formed with a curved contact portion and a press-fit portion wider than the contact portion, and an insulator for holding the contact. The insulator includes a holding hole for press-fitting and holding the press-fit portion. And an additional groove formed in the hole wall of the holding hole and extending in parallel with the holding hole. The holding hole and the additional groove have dimensions that allow the passage of the contact portion together. In the cable connector, wherein the press-fitting portion can be press-fitted into the holding hole with the passage of the contact portion to the additional groove, the contact is provided in a direction of insertion into the holding hole.
And a groove connected to the press-fitting portion on the opposite side of the contact portion.
A blocking portion, wherein the groove blocking portion is narrower than the holding portion.
With width and held by the insulator
In the state, the additional groove is fitted to the additional groove to substantially shut off the additional groove.
So that it bends and projects in the direction crossing the width direction.
And it shall be the feature of that.

[0007]

In the present invention having the above structure, first, the contact portion of the contact is inserted into the holding hole formed in the insulator and the contact is pushed. The press-fit portion of the contact is inserted into the additional groove of the insulator. Further, the contact is pushed in so that the groove blocking portion of the contact is inserted into the holding hole.
Then, in the contact assembling state, the press-fit portion blocks the holding hole and the groove blocking portion blocks the additional groove, so that there is no need to perform potting. In this assembled state, the contact portion of the contact is located in the receiving hole formed inside the distal end of the connector, and is configured to have a spring property by the portion held in the holding hole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is an explanatory view showing a connector body according to an embodiment of the present invention, wherein FIG. 1A is a plan view, FIG.
(C) is a bottom view, (d) is a side view, and FIG. 2 is an explanatory view in which a back shell is incorporated in the connector body.
Is a front view, (b) is a side view, (c) is A in (a).
A -A line cross-sectional view, illustrating 3 showing the embedded free state before the contact on the insulator of the connector body, FIG. 4
Is an illustration showing the hood molded in.
(A) is a plan view, (b) is a front view, (c) is a bottom view,
(D) is a partial cross-sectional side view.

As shown in FIGS. 1 (a), 1 (b), 1 (c) and 1 (d), the connector main body has an insulator 20 and a shell 40 integrally attached thereto.

As shown in FIGS. 2 (a), 2 (b) and 2 (c), a central portion of the connector body inside the insulator 20 is provided with:
It is formed so as to extend integrally with the holding hole 21 of the contact 10 and the additional groove in the connector connection direction (vertical direction in the drawing). One end of each of the holding holes 21 and the additional grooves 22 is open to the connection portion side of the contact 10, that is, to the cover 30 side. The other end is openly connected to a receiving hole 24 formed for inserting and receiving a mating connector. Note that reference numeral 4 in FIG.
0 is a shell, and reference numerals 50 and 60 are backshells.

[0012] The contact 10, as shown in FIG. 2 (c) and FIG. 3, the contact portion 11 at the distal end side, a press-fit portion 14 formed in the wide shape of the body portion, the press-fitting portion 14
And has a groove blocking portion 15 which is curved in the thickness direction on the side of the connection portion 12 .

The contact portion 11 of the contact 10 is
4 is located in the hollow portion of the receiving hole 24 through the holding hole 21 so as to come into contact with the contact portion of the contact (not shown) of the mating connector inserted into the connector 4.

The press-fitting portion 14 of the contact 10 is
1 is held in a fitted state, and the receiving hole 2
The contact portion 11 which is suspended at the hollow position of No. 4 has a spring property.

The groove blocking portion 15 of the contact 10 is inserted and fitted into an additional groove 22 through which the contact portion 11 passes.

As shown in FIG. 3, the size of the holding hole 21 is set such that the press-fit portion 14 of the contact 10 is press-fitted, and the height a of the connection between the holding hole 21 and the additional groove 22 is a. Is set to be substantially the same as the height c of the groove blocking portion 15 of the contact 10, and the width b of the additional groove 22 is set to be substantially the same as the width d of the groove blocking portion 15. Thus, the contact hole 2 of the contact 10 and the insulator 20
By setting the dimensional relationship between 1 and the additional groove 22,
The additional groove 22 includes the press-fit portion 14 of the contact 10 and the groove blocking portion 1.
5 is closed.

Next, after the contacts 10 are pressed into the insulator 20 as described above, the hood is attached by mold-in. 4 (a), (b), (c),
(D) shows a state in which the hood 70 is attached. According to the present invention, at the time of mold-in molding of the hood 70, the back shell 5 shown in FIGS. 2 (a), 2 (b) and 2 (c) is used.
Food 70 molding material serving resin flows into the 0,60, but never the resin flows around the contact contact portion 11 of the contact. In the figure, reference numeral 80 denotes a cable.

[0018]

As described above, according to the present invention, the additional groove through which the contact passes can be closed just by incorporating the contact into the insulator, and the need for potting work is eliminated. For this reason, the connector with a hood by mold-in molding can be manufactured at low cost without affecting the contact performance of the contact.
