Abstract

(57) [Summary] [Purpose] To provide a contact with a floating mechanism, yet realize a low height contact so that the distance between substrates is not increased. [Structure] The female contact 2 is divided into a contact portion A and a base portion B, and a leg 21 connects these portions. The leg 21 has a structure in which, for example, one end of the contact portion A is pulled out laterally and bent downward to reach the base portion B. This leg 21 has a floating function. The contact portion A easily swings freely in the left and right direction, and the position and the directionality are flexible. Therefore, even if there is some deviation in the position or directionality from the mating contact, both contacts will not be damaged.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to an electric connector having a contact having a floating function.

[0002]

[Prior Art]

 Many circuit boards are used in electronic devices. Various connectors are used to make circuit connection between circuit boards in electronic equipment. With the advancement of electronic technology, high-density mounting of circuit boards is progressing, and the miniaturization and miniaturization of electronic devices is being promoted.Accordingly, there is a demand for miniaturization of connectors that connect circuit boards. It is getting more intense.

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

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 due to the above-mentioned demand for miniaturization. It has become a value.

[Problems to be solved by the device]

 As mentioned above, when the size is required to be small and the dimensions are small, the accuracy of the contact position and verticality of the connector body is also increased. If it cannot be done, or even if it can be fitted, the mating of the contacts will scratch and the surface will be scraped at the time of mating, and the scraped powder at that time will scatter and cause a short-circuit accident or leakage accident. It often happens that the other party's contact is damaged.

Therefore, for example, as shown in FIG. 3, a narrow 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 mating with the other party, It was suggested that a so-called floating mechanism should be provided so as to be able to follow the direction even if there is a direction.

However, the provision of the floating mechanism between the contact portion of the contact and the substrate as described above increases the contact height by Δh, which increases the distance between the substrates and increases the density. There was a problem to be solved, which was against implementation.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a connector having a contact with a short height and a contact with a floating mechanism that does not increase the distance between substrates. is there.

[0009]

[Means for Solving the Problems]

 As shown in FIG. 1, a set of connectors having a male contact 3 and a connector having a female contact 2, which are fitted to each other, of which a connector having a female contact is included. Female contact 2 is as follows. The contact portion A and the base portion B in the portion of the female contact 2 that fits with the mating contact 3 are connected by a leg 21 pulled out from the tip of the contact portion A.

[0010]

[Action]

 Since the contact portion A and the base portion B are connected by the leg 21 pulled out from the tip of the contact portion A, the leg 21 fulfills a floating function and easily swings freely to the contact portion A. Give directionality flexibility.

[0011]

【Example】

 An electrical 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, in which 1 is a body of a connector made of an insulating material.

Reference numeral 2 denotes a female contact attached to the body 1, and here, a female contact having a hoe-shaped contact portion A having two corners is shown. The feature of this contact 2 is that it is divided into a contact portion A and a base portion B, and the contact portion A and the base portion B are pulled out from one end of one corner of the contact portion A and are located in the direction of the body 1. That is, they are connected by a leg 21 extending toward B. The leg 21 may be made of the same material as the contact part A and the base part B, and may be made separately from the contact part A and the base part B, and may be later welded, soldered or joined to the contact part A and the base part B. May be contacted.

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

For example, when the contact 2 has a height of 4 mm and a width of 2 mm, the leg 21 has a cross section of 0.3 to 0.5 mm in both length and width. If it is larger than this, the rigidity becomes too large and lacks flexibility, and if it is smaller, the rigidity becomes insufficient and bending and fitting may become impossible due to insertion force.

Reference numeral 22 denotes a protrusion provided on the base portion B, which prevents the contact portion A from being excessively pushed down when the mating contact 3 is inserted.

[0016]

Effect of the Invention According to the present invention, the contact portion and the base portion of the fitting portion of the contact in the connector having the female contact of the set of mating connectors are drawn out from the tip of the contact portion. Since the structure is connected by legs, the contact part can easily swing to the left and right, and it is highly flexible in its position and directionality. It has a remarkable effect that the contact can be easily fitted and removed without damaging the contact.
