Description

[Detailed Description of the Invention] The present invention relates to a female electrical connector that is mainly used by being attached to a connector housing, and the electrical contact portion for the male electrical connector is formed of a highly elastic metal member such as beryllium copper.
The aim is to increase the contact pressure and improve the reliability of electrical connections.

Conventionally, in this type of electrical connector, the electrical contact portion and the wire connection portion have been integrally formed from a copper plate, brass plate, or the like, which has good conductivity and malleability, and is easy to process.

Therefore, the springiness of the electrical contact part is regulated by the metal material, and under the constraint of making the electrical connector as small as possible, it is difficult to significantly improve the contact pressure even if the structure and shape are changed. Ta.

Furthermore, when inserting and connecting with a male electrical connector, it may be inserted in an unreasonable position where the axes intersect with each other, but the electrical contact part is also made of a material with emphasis on malleability as described above. Because of this, plastic deformation occurs and the contact pressure decreases, making it unusable.

The present invention was developed by focusing on the above-mentioned points, and by forming the electrical contact portion with a highly elastic metal member, the contact pressure is increased and plastic deformation is less likely to occur, while the wire connection portion is made of a highly elastic metal member. Our aim is to provide a highly reliable female electrical connector that can make a stable electrical connection by forming it from a copper plate or brass plate.

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

In FIGS. 1 and 2, A is a female electrical connector, which is composed of two members: an electrical connector portion A1 and a wire connection portion A2.

The electrical contact portion A1 has elastic clamping arms 2 on both sides of the substrate portion 1, and the supporting portions 2 are connected to the side wall plate portion 2a standing upright on the substrate portion 1.
and a curled portion 2b which is bent in an inverted U-shape with the tip extension portions facing inward.

The above structure is the same as the conventional one, but in the present invention, the entire structure is made of a highly elastic metal member such as beryllium copper, phosphor bronze, or spring steel.

Further, the substrate portion 1 has a trapezoidal shape that expands toward the rear,
A stepped portion 3 with a tapered surface 3a at the front is provided at the tip, and a ■-shaped notch 4 is provided at the rear.
The rear part of the substrate part 1 is wider than the front part by the same amount.

On the other hand, a horizontally elongated locking hole 5 is provided in the upright base of the side wall plate portion 2a of the elastic supporting arm 2 so as to be in contact with the base plate portion 1.

On the other hand, the electric wire connection part A2 has locking pieces 7 protruding from both sides of the connecting plate 6, and a pair of crimping clamping pieces 8 and 9 for the conductor and insulation coating of the electric wire continuously at the rear part.
This electric wire connection portion A2 is integrally formed with a non-highly elastic metal member such as a copper plate or a brass plate, as in the conventional case.

Next, assembly will be explained.

First, the wire connecting part is inserted from behind the electrical contact part A1, and the tip of the connecting plate 6 is brought into contact with the stepped part 3 of the base plate part 1.

Next, using a jig (not shown), the rear part of the substrate part 1 is pressed from the elastic supporting arms 2, 2 side.

As a result, the rear part of the substrate part 1 is reduced, and the ■-shaped notch 4
is closed, and at the same time, the locking piece 7 enters the locking hole 5, and the board part 1
and the connecting plate 6 are coupled so that they cannot be pulled out from the front or rear.

Note that since the locking piece 7 only needs to protrude by a small distance equivalent to the plate thickness of the elastic clamping arm 2, the cut width d of the ■-shaped notch 4 is
It is also small enough that it can be easily tightened with a small amount of press pressure.

In the above structure, the mating connector (male terminal) is fitted between the connecting plate 6 and the edge of the curled portion 2b of the elastic supporting arm 2, as is conventional. Since 2 is formed of a highly elastic metal member, the contact pressure is high, and the contact pressure is stronger than that of a conventional one made of copper plate or the like.

In addition, when inserting the male terminal, since the tapered surface 3a is formed at the tip of the board portion 1, the connection can be made smoothly.

In addition, since the elastic supporting arm 2 has strong elasticity, it does not easily deform even if it is repeatedly attached to and detached from the male terminal or is subjected to prying force, and does not suffer from springiness or failure.

Since the present invention has the above-mentioned precautions, it is possible to increase the contact pressure at the electrical contact part to the other connector, and to firmly connect the electrical contact part and the wire connection part.
In this case, since the connecting plate in the wire connecting portion comes into contact with the mating connector under high contact pressure, it is possible to provide a highly reliable female electrical connector with a stable electrical connection state.
