JPS604392Y2 - Connector female contacts - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention particularly relates to a female contact for a connector used for wiring inside an automobile.

As shown in FIG. 1 as an example, a conventional connector of this type has a crimp joint 2 formed on one side of a base 1 for connecting to an electric wire a, and a male terminal introduction port 3 formed on the other side of the base 1. A female contact consisting of an arch-shaped lower contact piece 4 formed between the lower parts and an elastic tongue piece 5 protruding from the upper part of the base 1 toward the male terminal introduction port 3 has a wire crimp joint ( (not shown), and a male terminal having a plate-shaped contact piece 7 formed on the other side is inserted into contact with the male terminal for connection.

In the female contact of such a connector, the contact between the male terminal and the contact is soft and it is easy to insert and remove it, but the strength of the elastic tongue piece 5 is low and it is easily deformed, and as it is repeatedly inserted and removed, it becomes permanently deformed. This often resulted in poor contact.

In addition, as shown in Fig. 2, there are other types of connectors.
There is a female type contact in which the distal end facing portion of the bifurcated piece 8 is formed as a contact portion 9 with a male terminal, and a male terminal as shown in FIG.

However, although the female contacts of such connectors have a high contact pressure with the male terminals, they have the disadvantage that a large force is required to insert and remove the male terminals.

In consideration of the above points, the present invention has been developed to reduce the amount of force required to insert and remove the male terminal, and the contact pressure is large, making it difficult to cause permanent deformation even when the male terminal is repeatedly inserted and removed, and to reduce the occurrence of contact failures. DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention provides a female contact of a connector that can be used, and will be described in detail with reference to the drawings below.

3 and 4 show an embodiment of the present invention, 11 is a base, 12 is a wire crimp joint, 13 is a male terminal inlet, 14
is a lower contact piece, and the structure of these parts is similar to the conventional one shown in FIG.

The elastic tongue piece 15 protruding from the base 11 is twisted at the middle part.

The twist angle is preferably about 45 degrees, but it may be selected to be larger or smaller depending on the thickness and material of the elastic tongue piece 15.

Although the strength of the elastic tongue increases significantly due to this twisting, sufficient elastic force remains.

16 is a reinforcing rib formed between the base 11 and near the base end of the elastic tongue piece 15, and when inserting the male terminal, the elastic tongue piece 15
It has the effect of reinforcing the force applied to the base end of.

If there is no need for reinforcement depending on the thickness, material, etc. of the elastic tongue, there is no need to provide it.

As described above, the strength of the present invention is increased by twisting the elastic tongue, so even if the male terminal is repeatedly inserted and removed, permanent deformation is unlikely to occur, and poor contact with the male terminal is prevented. This is less likely to occur, and since sufficient elasticity remains, the force needed to insert and remove the male terminal is small.
