[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector, and more particularly to, for example, an LST having a land.
And a connector that is sandwiched between a pair of electronic components such as a printed circuit board and the like to make an electrical connection between the two components.

[0002]

2. Description of the Related Art FIG. 8 shows a conventional general connector of this type. This connector includes contacts 11, 12 and an insulator 13. Insulator 13
Is formed with a through hole extending in the connection direction, and this through hole has small-sized openings at both ends. One contact 11 has a socket-like shape, and a projection 4 formed at a closed end thereof protrudes outside from one small-sized opening of the insulator 13 to form a contact portion with one electronic component 16. The other contact 12 has a pin-like shape and one end is received inside the socket-like contact 11, and a projection 14 formed at the other end with a conical flare 12 a extends from the other small opening of the insulator 13 to the outside. It protrudes to form a contact portion with the other electronic component 16.

[0003] These contacts 11, 12 are sandwiched between a pair of electronic components 16, and pressure is applied in the connection direction.
The contact portion 15 of the socket-shaped contact 11 rides on the flare 12a of the pin-shaped contact 12, and resiliently repels each other. This repulsive force acts as a contact force with the pad of the electronic component 16.

[0004]

In such a conventional connector, two contacts having different configurations are required for each connector, and there is a problem in management and cost. At the time of assembling, it is necessary to insert two sets of contacts into a through hole of the insulator one by one in a fitted state, and at this time, the insulator and the contacts are not yet locked, so that handling is difficult. There is a problem in terms of assembly workability. In combination with these problems, the conventional connector as described above suffers from a disadvantage that the manufacturing cost is increased. An object of the present invention is to provide a connector which is excellent in management and assembling workability and has a low manufacturing cost.

[0005]

According to the present invention, there is provided a connector which is sandwiched between a pair of electronic components and electrically connects the two electronic components. The connector comprises an insulator and two contacts having the same configuration. The insulator has a through-hole extending in the connection direction corresponding to the land of the electronic component, and the through-hole is provided with a projection for engaging one end of each contact. , The contact is substantially U
A connector characterized in that it is received in the through-hole of the insulator in the shape of a letter-shaped leaf spring and partially in contact with each other and in the opposite direction to each other, is obtained.

[0006]

In the connector according to the present invention, when pressure is applied in the connecting direction by sandwiching the contacts between the electronic components in a state where the contacts are inserted into the through holes of the insulator, the contacts come into contact with each other at the contact portion, and the electronic components at the curved portion. And electrically connect the two electronic components.

1 to 5 show an embodiment of the connector of the present invention. As shown in FIG. 2, each of the contacts 1 and 2 is formed of a substantially U-shaped leaf spring, one end of which engages with the insulator 3, and the other end 5 connects the contacts 1 and 2. Locking between the contacts 1 and 2 is also performed. In addition, the curved portions 4 of the connectors 1 and 2 form contact portions with the electronic components. A through hole is formed in the insulator 3 in the connection direction, and two types of protrusions 7 are provided in the through hole.

FIG. 1 shows a state in which two contacts 1 and 2 are inserted into a through hole of an insulator 3. One end of each of the contacts 1 and 2 is engaged with the projection 7 of the through hole of the insulator 3 and is in surface contact with each other near the other end. The curved portion 4 protrudes outside from the through hole. The contacts 1 and 2 themselves have not yet been deformed in this state. FIG. 5 shows a state in which a pair of electronic components (not shown) are assembled to the connectors 1 and 2 in such a state. Each contact 1, 2 is deformed,
At the end portion 5, two points contact each other, and
Is in contact with the pad of the electronic component. At this time, the contacts 1 and 2 elastically deform and repel each other in the connection direction, and the repulsive force becomes a contact force between each other and the pad of the electronic component.

FIGS. 6 and 7 show another embodiment of the connector according to the present invention, in which each of the contacts 1 and 2 is also formed of a U-shaped leaf spring. In FIG. 7, the left side shows a state in which the contacts 1 and 2 are inserted into the through holes of the insulator 3, and the right side shows a state in which electronic components are assembled thereto. In the assembled state of the electronic component, both contacts 1 and 2 were in a two-point contact state in the previous embodiment (see FIG. 5). State (see FIG. 7). The operating principle is the same as in the previous embodiment.

[0010]

[Effects of the Invention] In the connector of the present invention, it is only necessary to use a contact having a single configuration, so that management and cost are greatly reduced, and assembly can be performed in a row unit, so that workability is greatly improved. In addition, the combination thereof greatly reduces the manufacturing cost.
