JPS5826154B2 - Contacts for electrical connectors - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to contacts used in electrical connectors.

Recently, things such as leadless ICs, leadless LSIs, and printed circuit boards (herein referred to as "daughter boards") have been replaced with other printed circuit boards (herein referred to as "daughter boards").
Various types of connectors, commonly called multi-pole connectors, have been developed for mounting on motherboards (also called "motherboards").

This type of connector generally has a structure in which a step is provided on the inner side of a rectangular frame-shaped housing, and a number of contacts are incorporated along the step. The circuitry on the daughterboard can be connected to the circuitry on the motherboard by matingly attaching the talkboard to the connector and making contact with the contacts.

However, in the conventional contacts, the tip of the flat part is bent at an obtuse angle with respect to the holding part held in the housing. When the angle between the contact and the holding part is narrowed, the flat part comes into contact with the daughter board over its entirety, resulting in uncertain contact between the contact part of the contact and the connection part of the daughter board. There is a risk.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a contact for an electrical connector with a simple structure and at a low cost, which is capable of reliably contacting a contact portion even with a connection portion provided on a part of a plane.

The present invention will be described below using examples with reference to the drawings.

First, referring to FIGS. 1 and 2, a conductive contact 1 made of a plate-shaped material is held by a holding portion 11 in an insulating housing 2 in a penetrating state.

The terminal portion 12 of the contact 1 protruding from the lower surface of the housing 2 is inserted and connected to the through hole 31 of the motherboard 3 when the housing 2 is mounted on the motherboard 3 as shown in FIG.

On the other hand, the portion of the contact 1 exposed on the upper surface of the housing 2 includes a first curved portion 13 that is curved following the holding portion 11 and bent at a substantially right angle to one side with respect to the holding portion 11; It integrally has a contact portion 14 located at a position forming an obtuse angle θ1 with respect to the holding portion 11 when viewed from the curved portion 13 .

Furthermore, a second curved portion 15 curved at an obtuse angle θ2 in the opposite direction to the first curved portion 13 is provided between the first curved portion 13 and the contact portion 14.

In this way, a plane part 16 is formed between the first curved part 13 and the second curved part 15, which is substantially perpendicular to the extension axis of the holding part 11 and the terminal part 12, and a flat part 16 is formed between the first curved part 13 and the second curved part 15. An inclined portion 17 is formed between the curved portion 15 and the curved portion 15 .

When the daughter board 4 is fitted and attached to the stepped portion 21 of the housing 2 in which such a contact 1 is incorporated, as shown in FIG. As a result, the portion of the contact 1 exposed on the upper surface of the housing 2 is bent as shown.

At this time, since the second curved part 15 is provided between the first curved part 13 and the contact part 14, it is possible to prevent parts other than the contact part 14 from coming into contact with the daughter board 4. be done.

Therefore, contact between the contact portion 14 of the contact 1 and the connection portion 41 of the daughter board 4 is ensured.
