DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot-swap connector.

[0002]

2. Description of the Related Art A hot-swap connector for connecting a plurality of terminals including a power terminal, a ground terminal, and a signal terminal of an electronic circuit board constituting an electronic device or the like without disconnecting a main power supply of the electronic device or the like. In order to be able to insert and remove the electronic circuit board, it is common that each terminal is configured not to contact at the same time at the time of mating of the connector, but to contact the ground terminal, the power terminal, and the signal terminal in this order. It is a target. This is to prevent the fluctuation of the power supply voltage at the time of insertion / removal from affecting the circuit for passing the signal.

In the above-described hot-swap connector, an arc is generated between the male terminal and the female terminal when the connector is fitted. Depending on the strength of the arc, there is a problem that the contacts of both the male terminal and the female terminal are damaged by the heat of the arc to cause a poor contact.

Therefore, in order to solve this problem, two contacts are provided at each terminal of the male connector and the female connector, and an arc is generated at one contact and an arc is generated at the other contact. And a terminal provided with a terminal for ensuring contact reliability.

Hereinafter, an example thereof will be described with reference to the drawings.

2 (a) and 2 (b), the male connector 5 includes three male terminals 1 and a male connector fitting body 3 for fitting with the female connector 6. A cutout 7 is provided at the tip of the male terminal 1.

The female connector 6 comprises a female terminal 2 and a female connector fitting 4 for fitting with the male connector fitting 3. The female terminal 2 is arranged on the female fitting body 4 so as to sandwich the male terminal 1 when the male connector 5 and the female connector 6 are fitted.

In FIG. 2 (b), the male terminal 1 of the male connector 5 is first contacted with the female terminal 2 when the connector is fitted. The first contact 8 of the male terminal provided on the side where the notch 7 does not exist, and the notch 7 of the male terminal 1 for contacting the female terminal 2 after the first contact 8 contacts. And a second contact 9 of a male terminal provided on the side having

Further, the female terminal 2 contacts the first contact 10 of the female terminal which contacts the first contact 8 of the male terminal when the connector is fitted. The second contact 11 of the female terminal which later contacts the second contact 9 of the male terminal
And are provided.

In FIG. 2B, when the male terminal 1 and the female terminal 2 come into contact with each other, the first contact 8 of the male terminal and the first contact 10 of the female terminal are initially connected. Contact
Next, the second contact 9 of the male terminal and the second contact 1 of the female terminal
1 comes into contact last. When the contacted male terminal 1 and female terminal 2 are separated, the second contact 9 of the male terminal and the second contact 11 of the female terminal are separated first, and the male terminal The first contact 8 and the first contact 10 of the female terminal are finally separated.

In the above-mentioned connector, when the male terminal 1 and the female terminal 2 come into contact with or separate from each other, the first contact 8 of the male terminal and the first contact 10 of the female terminal are always connected. An arc is generated and each contact is damaged. No arc is generated between the second contact 9 of the male terminal and the second contact 11 of the female terminal, so that there is no damage.

Therefore, the contact reliability between the second contact 9 of the male terminal and the second contact 11 of the female terminal can always be ensured.

[0013]

However, in the above-mentioned conventional example, the notch 7 of the male terminal 1 is very small.
The first contact 8 of the male terminal that generates an arc is close to the second contact 9 of the male terminal that does not generate an arc. Therefore, when the first contact 8 of the male terminal and the first contact 10 of the female terminal that generate an arc first contact, the second contact 9 of the male terminal that does not generate an arc and the female Although it does not yet contact the second contact 11 of the side terminal, it is in a very close position.

Therefore, when the connectors are mated due to an erroneous operation of the operator, the male connector 5 and the female connector 6 will be fitted with the relative angle deviated from the normal angle. In such a case, the second contact 9 of the male terminal and the second contact 11 of the female terminal may come into contact first. In this case, an arc is generated between the second contact 9 of the male terminal and the second contact 11 of the female terminal, which should ensure contact reliability, resulting in damage and poor contact. There was a problem that.

Further, in order to provide the notch 7 at the end of the male terminal 1, precision processing is required, which leads to deterioration in mass productivity and yield, and increases the manufacturing cost of the connector. there were.

The present invention has been made in order to solve the above-mentioned problems, and has a contact that does not cause a contact failure due to an arc, has good mass productivity and good yield when manufacturing a connector, and has a low manufacturing cost.
