BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrical connector having a contact having a floating function.

[0002]

2. Description of the Related Art Many circuit boards are used in electronic equipment. Various connectors are used for circuit connection between circuit boards in an electronic device. With the development of electronic technology, high-density mounting of circuit boards has been progressing, and the miniaturization of electronic devices has been promoted, and with this, the demand for finer connectors for connecting circuit boards has become even more intense. Has become.

FIG. 2 shows a set of mating contacts in a connector for connection between circuit boards (hereinafter referred to as "boards") which have been widely used in the past.
Reference numeral 1 denotes a connector body, and reference numeral 2 denotes a socket-side contact attached to the connector body 1. A so-called tuning fork type contact portion having a tuning fork shape is exemplified. Reference numeral 3 denotes a connector contact which fits into the socket-side contact 2, and the contact portion is a bar-shaped or plate-shaped plug contact. In FIG. 1, the body of the connector to which the plug contact is attached is omitted.

[0004] The dimensions of the contacts in the above-mentioned connector for board-to-board connection are, for example, such that the height (h) is 4 mm or less, the width (w) is 3 mm or less, and the thickness is 0.5 mm or less in accordance with the above demand for fineness. Value.

[0005]

As described above, miniaturization is required, and as the dimensions are reduced, the required accuracy of the position, verticality, etc. of the contacts attached to the connector body is also increased, and the desired accuracy is obtained. If they are not satisfied, they cannot be mated with each other, or even if they can be mated, at the time of mating, the contacts will scratch each other and the surface will be shaved, and the shavings at that time will be scattered, causing a short circuit accident or leakage Cause an accident,
Accidents that damage the contact of the other party occur frequently.

Thus, for example, as shown in FIG. 3, a thin neck portion 5 or a spring portion is provided between the contact portion of the contact 2 and the substrate 1 so that the contact is slightly positioned when fitted with the counterpart. It has been proposed to provide a so-called floating mechanism that has flexibility so that it can follow the direction even if there is a sword in the direction.

However, providing the floating mechanism between the contact portion of the contact and the substrate as described above increases the contact height by Δh.
There has been a problem to be solved in which the distance between the substrates is increased to go against high-density mounting.

The present invention has been made in view of the above situation, and has as its object to provide a connector having a contact with a floating mechanism which does not reduce the height of the contact, that is, does not increase the distance between substrates.

[0009]

SUMMARY OF THE INVENTION As shown in FIG. 1, a pair of mating connectors, each of which is composed of a connector having a male contact 3 and a connector having a female contact 2, is provided. The female contact 2 is made as follows.
That is, the male connector in the female contact 2
The contact portion that fits with the contact 3 is the contact portion A and the base portion B.
And the contact portion A and the base portion B are
It is made of a conductive material with spring properties that is pulled out from the end
The base 21 is connected to the upper surface of the base B by the
A projection 22 for preventing depression of the contact portion A is provided;
Structure.

[0010]

[Effect] The contact portion A can be easily swung right and left, and the position and the direction can be adjusted.
To provide flexibility, the legs 21 are connected to the male contacts 3
While maintaining the spring properties of the contact portion A against
It must be soft. This is shown in the left of FIG.
It must be easy to swing back and forth to the right, but legs 21
It can be realized by doing. However, when thinner, male contours
When the leg 3 is inserted into the contact portion A, the leg 21 is bent to the left.
Inadvertent addition is added to the contact portion A, resulting in a change in the contact portion A.
Will cause shape. In the present invention, the base B
A projection 22 for preventing the contact portion A from being pushed down
Because of this, the flexibility of the leg 21 is not
Contact part A sinks below necessary by inserting tact 3
Of the contact portion A after the male contact 3 is inserted.
Flexibility is maintained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An electric connector according to the present invention will be described below with reference to the drawings. FIG. 1 shows a specific example of a contact portion of a connector according to the present invention, where 1 is a connector body made of an insulating material.

Reference numeral 2 denotes a female contact attached to the body 1, and here, a female contact having a hook-shaped contact portion A having two corners is shown. The feature of the contact 2 is that it is divided into a contact portion A and a base portion B.
And the base B are connected to each other by a leg 21 which is pulled out from the tip of one corner of the contact portion A and extends toward the base B in the direction of the body 1. The leg 21 may be made of the same material as the contact part A and the base B, and is made separately and independently from the contact part A and the base B, and later connected to the contact part A and the base B by welding, soldering or other joining means. May be contacted.

The female contact 2 is made of a conductive material having a spring property, for example, a copper alloy such as brass, beryllium copper, nickel silver, cadmium copper, etc., which has been widely used as a contact material of a conventional connector. Can be mentioned. The method of manufacturing the female contact may be any known method, for example, it can be made by stamping and forming from a copper alloy sheet material.

The leg 21 has, for example, a height of the contact 2 of 4 m.
m, when the width is 2 mm, the cross section is 0.3 to 0.5
mm. If it is larger than this, the rigidity becomes too large and lacks flexibility, and if it is smaller, the rigidity becomes insufficient and it may be impossible to bend and fit by the insertion force.

As described above, the protrusion 2 is formed on the upper surface of the base B.
2 is provided. This prevents the contact portion A from being excessively pushed down when the mating contact 3 is inserted.

[0016]

[Effect of the Invention] [The contact part A and the base B are the tip of the contact part A.
Legs made of a conductive material having spring properties and drawn from
21] and [the upper surface of the base B]
A projection 22 for preventing the contact portion A from being pushed down.
To make the legs 21 thinner.
To easily swing the contact part A to the left and right to accommodate the position and direction.
The male contact 3
The leg 21 bends greatly and the contact portion A is not intended
The addition may cause deformation of the contact portion A or the contact portion
A is prevented from sinking more than necessary, male contact
3. The flexibility of the contact portion A after insertion is maintained. for that reason,
Even if there is a diagonal position and direction between the contacts of the mating partner, the contacts can be easily fitted and removed with a small insertion force without damaging both contacts.
