Electrical connector

Abstract

The present invention provides an electrical connector having contacts connected to electrical wires and a housing with sockets accommodating the contacts. The housing includes a blocking structure and a slope provided on the socket, so that the reversely inserted contact must butt against the blocking structure, thereby preventing further insertion of the contact. When the contact is correctly inserted into the socket, since the contact has an edge and a slope, the edge is guided by the slope of the housing, and the slope of the contact avoids abutting with the blocking structure and is guided by the blocking structure, so that the contact can be inserted smoothly. head.

Description

technical field [0001] The present invention relates to an electrical connector having contacts connected to electric wires and a housing with sockets (cavities) accommodating the contacts. Background technique [0002] Conventionally, there is known a technique for assembling an electrical connector by inserting contacts into sockets (cavities) provided in a housing. [0003] In the electrical connectors described above, although there is little problem with the case of round contacts, there is a possibility that square contacts are inserted into the housing in the wrong direction, resulting in failure of the connector engagement. In order to avoid such mis-insertions, especially counter-insertions, measures have been taken. These measures typically have both the contacts and the housing have irregularities configured to only allow insertion of the contacts into the housing in one orientation. [0004] For example, Japanese Patent Laid-Open No. 10-144379 describes that th...

But this is still not enough, because the leading edge of the small protrusion tends to scrape against the inner wall of the housing, allowing reverse insertion

[0009] Also, even when the contacts are inserted in the correct orientation, it can be difficult to get the contacts smoothly across the level difference between the large diameter area near the jack opening and the small diameter area at the back of the jack opening

This is especially difficult when electrical connectors are attached to wires with a cross-section of 0.22 to 0.5 mm
