DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector mounted on a board, and more particularly to a connector provided with a locator for positioning a terminal portion of a contact with a through hole provided in the board.

[0002]

2. Description of the Related Art FIG. 8 shows a conventional connector.
8A is a perspective view, and FIG. 8B is a partially enlarged sectional view.

[0003] As shown in FIG.
The insulator 2 having the locator mounting portion 21, the plurality of contacts 3 provided on the insulator 2, and the terminal portions 32 of the plurality of contacts 3 are inserted, and the plurality of terminal portions 32 are respectively mounted on a substrate (not shown). The locator 4 has a plurality of insertion holes 41 for positioning with respect to the through holes, and is provided to the locator mounting portion 21.

The upper opening of the insertion hole 41 of the locator 4 is chamfered to facilitate the insertion of the terminal portion 32 of the contact 3.

[0005]

When the terminal portions of the contacts of the connector are inserted into the through holes of the substrate, it is difficult to insert the terminals into the through holes if the positions of the terminal portions of the contacts vary. Therefore, as described above,
In a connector of the type mounted on a board, a locator for positioning a terminal portion of a contact is generally used.

However, before the locator is mounted on the insulator, the positions of the terminal portions of the contacts may vary, making it difficult to insert the terminal portions of the contacts into the insertion holes of the locator.

Therefore, in the connector assembling process, in order to facilitate the operation of inserting the terminal portion of the contact into the insertion hole of the locator, it is desirable to enlarge the insertion hole of the locator.

However, in order to improve the positional accuracy of the terminal portion of the contact, which is the original purpose of the locator, it is desirable to reduce the insertion hole of the locator.

Thus, there has been a conflicting demand for the size of the locator insertion hole. Therefore, conventionally, a compromise size has been adopted as the size of the insertion hole of the locator. As a result, the assemblability of the connector and the positioning accuracy of the terminal portion of the contact were insufficient.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a connector which has good assemblability of a connector and high positional accuracy of a terminal portion of a contact.

[0011]

According to a first aspect of the present invention, there is provided a connector for aligning an insulator, a plurality of contacts provided on the insulator, and terminal portions of the plurality of contacts.

When displaced in the direction, the first and second insertion holes coincide with the contact arrangement direction, the cross-sectional area of the insertion hole of the locator increases, and one of the first and second locator plates is placed one on top of the other in a state of being overlapped. When the first and second locator plates are relatively slid to match the contact arrangement direction x, the first and second insertion holes are shifted in the contact arrangement direction, and the cross-sectional area of the locator insertion hole is reduced.

[0013]
