Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a connector including a female contact and a male contact inserted and connected to the female contact.

[Conventional technology]

Recently, there is a connector shown in FIG. 6 for indirectly connecting electric wires to wiring on a printed circuit board or the like.

Referring to FIG. 6, a conductive male contact 1 made in the shape of a square bottle or a round pin is held by an insulator and connected and fixed to wiring on a board by soldering. A conductive female contact 3 held by an insulator is detachably connected to such a male contact 1. The female contact 3 has a crimp portion 7 for crimp-connecting the electric wire 5, and a pair of contact spring pieces 9 for receiving the male contact 1 and making electrical contact therewith. The space between the pair of contact spring pieces 9 serves as a male contact insertion path. The crimp portion 7 of the female contact 3 holds the electrically insulating sheathing portion of the electric wire, and is connected to the core wire of the electric wire 5. A male contact 1 is inserted between the pair of contact spring pieces 9. The inserted male contact 1 is sandwiched between the contact spring pieces 9.

This provides a spot-tight connection. The female contact 3 is also held by the insulator.

[Problem that the invention seeks to solve]

However, in such a connector, there is a problem that when the male contacts 1 and the female contacts 3 are mounted in a high density, the contact spring pieces 9 of the female contacts 3 cannot be made large, so that the range in which they can make elastic contact becomes small.

Further, in the male contact 1, as the density increases, the strength becomes insufficient, making it difficult to develop the structure.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a connector that can accommodate increased density of male and female contacts.

CJ Lower Date [Means for Solving the Problems] According to the present invention, in a connector including a linearly extending male contact and a female contact having a male contact insertion path for receiving the male contact, A connector is obtained in which the contact insertion path is gently curved and extended, while the male contact is curved within elastic limits according to the male contact insertion path.

〔Example〕

1 to 4 show a connector according to an embodiment of the present invention. The illustrated connector includes an insulator 20,
It has a plurality of female contacts 22 incorporated inside the insulator 2o. The female contact 22 is
It has a contact portion 24 and a terminal portion 26 that are incorporated inside the insulator 2°. The contact portion 24 of the female contact 22 is.

The contact piece 28 has a U-shaped cross section and includes a pair of opposing contact pieces 28 that are spaced apart from each other and define a male contact insertion path 27. The male contact insertion path 27 extends in a gently curved manner. That is, each of the pair of contact pieces 28 is 9
They are gently curved in the same direction with a radius of curvature R.

It is assumed that the contact piece 28 itself has a rigid structure that does not substantially deform, and the width of the male contact insertion path 27 is also substantially fixed.

Each female contact 22 is installed inside a plurality of holes 30 formed through the insulator 20. The plurality of holes 30 are formed in parallel in the insulator 20. Hole 30 is.

It has a contact piece accommodating portion 31 formed obliquely with respect to the thickness direction axis of the insulator 20. The contact portion 24 of the female contact 22 is incorporated into this contact piece accommodating portion 31 .

The female contact 22 is located at the top of the terminal portion 26.

It has a retaining piece 32 formed by cutting and raising a part of the terminal part 26.

The hole 34 has a terminal holding portion 34 . The retaining piece 32 of the terminal portion 26 is positioned in the terminal portion holding portion 34 . By engaging the engagement piece 32 with the protrusion 36, the female contact 22 is prevented from coming off upward. A lower portion of the terminal portion 26 projects downward from the lower surface of the insulator 20. An electric wire is connected to the vicinity of the lower end of the terminal portion 26 by an appropriate connecting means such as soldering.

On the other hand, between the pair of contact pieces 24 of the female contacts 22, a linearly extending flat plate-shaped male contact 4o having a plate thickness that allows a clearance fit is inserted. male contact)
The tip of 40 is shaped like an arrowhead to facilitate insertion.

The male contact 40 is fixed to a mating insulator 42 that is combined with the insulator 20 incorporating the female contact 22.

It is desirable that the material of the male contact 40 is highly elastic.

At the time of connection, the male contact 40 is inserted through a guide portion 44 formed by slightly expanding the upper end of each contact piece 24 of the female contact 22 outward.

In this insertion, the plate thickness direction of the male contact 40 is inserted into the contact piece 24.
This is done in accordance with the mutual spacing direction. male contact 4
0 is bent and deformed and inserted along the gap between the pair of contact pieces 24 of the female contact 22, as shown in FIG. Thus, the male contact 40 can establish electrical contact with the female contact 22 due to its elasticity.

Further, when the male contact 40 is separated from the female contact 22, the shape changes due to its own elastic force. [Effects of the Invention] As described above in the embodiments, according to the present invention,
This is because the male contact is elastic and deforms elastically in the gap between the female contact and makes contact.

A connector is obtained in which female contacts can be arranged in high density on an insulator.
