- the entire contact 50 is covered with a resin, that is, a dielectric, except for the portions where exposure such as the contact portion 51 and the terminal portion 55 cannot be avoided, and the range exposed to air is small.
- the upper contact group 8 is covered with a dielectric having a dielectric constant larger than that of air, the impedance can be kept low.
- the holding power of the lower contact group 7 and the upper contact group 8 can be increased.
- the assembled connector 1 is shown in FIGS. 11-13.
- the connector 200 includes a shell 201, ground plates 202 and 203, a mid plate 204, a main body molded part 205, a lower contact group 206, an upper contact group 207, an upper contact insert part 208, and a rear shield 209. As can be seen from comparison with FIG. 1, these parts correspond to members of the same name of the connector 1. Hereinafter, differences from the connector 1 will be described. Please refer to the description of the corresponding part of the connector 1 as necessary.
- the upper contact insert component 9 is formed such that the contacts 50 are arranged on the same plane at a predetermined pitch, and the resin occupies a region surrounded by the press-fit portion 52, the bent portion 53, and the leg portion 54. .
- the upper contact insert component 208 is formed between the contact press-fitting portion 222 and the bent portion 224 so that the contacts are arranged on the same plane at a predetermined pitch. It is formed so as to cover the straight portion, that is, the insert mold portion 223.
- the upper contact insert part 208 is the same as the connector 1 in that the upper contact insert part 208 is arranged with a slight gap on the direction D2 side of the rear end 227 of the lower contact group 206. Therefore, the effect of preventing the displacement of the lower contact group 206 toward the direction D2 in the upper contact insert component 208 can be obtained in the same manner as the connector 1.
- the upper contact insert part 9 is supported from the direction D2 side by the rear shield 10.
- the upper contact insert part 208 is not in contact with the rear shield 209.
- the upper contact group 207 is integrally held by the upper contact insert part 208 and the lower contact group is formed by the upper contact insert part 208 in a simpler structure than the connector 1. An effect of preventing the rearward displacement of 206 can be obtained.
- each contact is held at an equal pitch, but the present invention is not limited to this. There may be variations in pitch.
