About.

[0002]

2. Description of the Related Art Conventionally, as a connector such as a connection socket for connecting a connector such as a data input / output plug to an electronic device, there is one shown in FIG. 16 (Japanese Utility Model Application Laid-Open No. 2-115280). Reference).

That is, in the drawing, a connector has a tin-plated terminal portion 60 soldered to a printed board at one end and a gold plating capable of contacting a contact portion of a mating connector at the other end. A plurality of substantially L-shaped contact pieces 62 each having a contact portion 61 formed thereon, a terminal block 64 for holding the contact section 61 on the outer surface of the holding section 63 in a state where each of the contact pieces 62 is penetrated and supported,
4 is the terminal portion 6 of each contact piece 62 supported by the terminal block 64.
Shield cover 6 that surrounds 0 in a state of protruding outside
5 is included.

[0004]

However, such a conventional connector has the following various problems. That is, in the conventional connector, when each contact piece 62 is supported by the terminal block 64, each contact piece 62
Into the terminal block 64 and penetrate through the groove 64 a provided in the terminal block 64, and insert the tip of the contact portion 61 into a small hole (not shown) at the tip of the holding portion 63 provided in the terminal block 64. And the contact portion 61 is held on the outer surface of the holding portion 63.

In this configuration, there is a gap in the support portion of the terminal block 64 that penetrates the contact piece 62, and the flux generated when the terminal section 60 is soldered to the printed circuit board passes through the gap toward the contact section 61. And may adhere to the contact portion 61. When the flux adheres to the contact portion 61 in this manner, a contact failure between the contact portion 61 and the contact portion of the mating connector occurs.

Further, in the above-described conventional state in which the contact pieces 62 are supported on the terminal block 64, the support state of each contact piece 62 cannot be said to be uniform, and the contact portion 61 and the contact portion of the mating connector are not supported. The contact pressure becomes non-uniform for each contact piece, and the uniformity of the contact pressure cannot be maintained even in the whole product, and the reliability of the electrical connection is lacking.

Further, since a troublesome process of supporting each contact piece 62 on the terminal block 64 is required, there is a problem that the number of manufacturing steps is increased.

Further, in the conventional connector, when the terminal portions 60 are projected from the terminal block 64, their pitches are not uniform, so that the terminal portions 60 are not soldered to the printed circuit board before soldering. When the terminal is inserted into the hole for inserting the terminal portion on the printed circuit board side, it is difficult to position the terminal into the hole, and there is a problem that the insertion is troublesome.

In the conventional connector, a projection 65a is provided on the inner surface of the shield cover 65 as a stopper for preventing the connector from being easily detached when connected to the mating connector. At the time of connection, this projection is configured to be in pressure contact with the outer surface of the shield cover of the mating connector.However, due to frequent insertion and removal of the connectors, the pressure contact state gradually increases due to wear of the projection 65a, etc. There is also a problem that it disappears.

Therefore, the present invention eliminates the influence of the flux generated when soldering the terminal portion to the printed circuit board on the contact portion, thereby improving the reliability of the electrical connection and improving the terminal portion on the printed circuit board side. The objective is to facilitate the alignment with the hole for insertion and to improve the reliability of the product by improving the reliability of the stopper function when connecting the connector to the mating connector.
