Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a connector suitable for electrically connecting an electronic device such as a computer to an external device.

[Conventional technology]

As this type of connector, a connector as shown in FIG. 3 is considered. The connector shown in FIG.
Reference numeral 50 denotes a mold base 3 having a plurality of cylindrical contact parts 5 and a protective wall part 6 surrounding the contact parts 5 projecting from the front surface 3a thereof, and a cover member 4 mounted so as to cover the mold base 3. And a connector body 2 composed of

In the contact hole 5a of each contact portion 5, a contact metal fitting, which is caulked and fixed to the electric wire 14 branched in front of the clamp metal fitting 17 of the cable 9 inserted in the cover member 4, as shown in FIG. (Socket bracket 1
1) is incorporated.

In assembling this socket fitting 11, as shown by the one-dot chain line in FIG. 5, the cross section provided inside the mold base 3 with the lid 20 provided on the mold base 3 opened is semicircular. Socket bracket 11 on the mounting part 22
Insert the socket part of the socket fitting 11 into the contact hole 5a so that the caulking part 11a is located, and then cover 20
Is closed as shown in FIG. 5, and the caulking portion 11a is pressed by the pressing portion 24 having a semicircular cross section provided on the lid portion 20 thereof.

After assembling the socket fitting 11 into the mold base 3 in this way, the mold base 3 is inserted into the cover member 4,
The claw portion 26 of the mold base 3 is fitted into the locking hole 27 of the cover member 4 to assemble the connector 1.

[Problems to be solved by the device]

In the connector 1 having the above-described structure, when the socket fitting 11 is caulked and fixed to the electric wire 14, a part of the core wire (for example, copper foil wire) of the electric wire 14 is shown by a chain line in FIG. As described above, it may protrude (hereinafter, this protruding portion is referred to as the protruding portion 14a). Wire 1
When the connector 1 is assembled with a part of the core wire 4 protruding, the protruding portion 14a comes into contact with the socket metal fitting 11 or the like inserted in the adjacent contact portion 5 as shown by the alternate long and short dash line in FIG. A short circuit may occur.

In view of such a point, an object of the present invention is to provide a connector in which, when a contact fitting is caulked and fixed to an electric wire, even if a part of the core wire of the electric wire protrudes, a short circuit or the like caused by the protrusion is hard to occur.

[Means for solving the problem]

In order to achieve the above object, the connector according to the present invention comprises:
A connector main body, a plurality of contact portions that are arranged in parallel with the connector main body, in which contact metal fittings that are crimped and fixed to a terminal branch electric wire of a connection cable are incorporated, and a lid portion that is covered so as to cover the crimped portions of the contact metal fittings are provided. And a partition wall is erected on the connector body side so as to partition between adjacent crimped portions of the contact fitting, and a groove fitted to the partition wall is provided in the lid portion. Is characterized by.

[Action]

In the connector according to the present invention configured as described above, even if a part of the wire protrudes from the core wire of the electric wire, the extension of the protruding portion is blocked by the partition wall and the lid portion and does not reach the adjacent contact portion. . Therefore, even if a part of the core wire of the electric wire protrudes, a short circuit or the like due to it does not occur.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 are cross-sectional views showing a main part of an embodiment of a connector according to the present invention.

The parts other than the appearance and characteristic parts of this example are substantially the same as those of the connector 50 shown in FIGS. 3 to 5 described above, so that the parts corresponding to the parts shown in FIGS. The same reference numerals are given and their duplicate description is omitted.

In this embodiment, as shown in FIGS. 1 and 2 corresponding to the above-mentioned FIG. 5, between the mounting portions 22 of the mold base 3 which is the main portion of the connector 1, that is, the mounting portions 22 are mounted there. The partition wall 15 is erected so as to partition between the adjacent crimped portions 11a of the contact metal fittings 11 to be placed, and the lid portion 20
A groove 25 that fits into the partition wall 15 is provided.

Therefore, when the lid 20 is closed with the socket fitting 11 inserted in the contact portion 5, the caulking portions 11a of the socket fittings 11 are completely separated by the partition wall 15 and the lid 20. As a result, even if a part of the core wire of the electric wire 14 is protruding, the extension of the protruding portion is blocked and does not reach the adjacent contact portion 5. Therefore, even if a part of the core wire of the electric wire 14 protrudes, a short circuit or the like due to it does not occur.

〔The invention's effect〕

As is apparent from the above description, according to the connector of the present invention, when the contact fitting is caulked and fixed to the electric wire, even if a part of the core wire of the electric wire protrudes, the extension of the protruding portion due to the partition wall and the lid is extended. Is blocked and does not reach the adjacent contact part. Therefore, even if a part of the core wire of the electric wire protrudes, it is possible to prevent a short circuit or the like due to the protrusion.
