The present invention relates to a connector suitable for high-speed transmission of electrical signals. Specifically, the present invention relates to an insulating housing structure in which a plurality of terminals included in a connector can be arranged and fixed so as to maintain impedance matching.

A connector used for transmitting an electrical signal or the like generally includes an insulating housing that holds one terminal group and the other terminal group facing each other, and an outer conductor shell that houses the housing. There is. For example, the connector described in Japanese Patent No. 2011-233337 (Patent Document 1) is a plurality of terminals arranged at intervals from each other, one terminal group arranged at the upper part, and arranged at the lower part. A plurality of terminals arranged so that the other terminal group faces each other, an insulating terminal holding member (housing) that holds each terminal, and a shield that covers the housing that holds each terminal, and the housing is made of synthetic resin A plurality of grooves for holding a plurality of terminals, a terminal holding portion formed in a plate shape, and a back portion provided with a plurality of holes through which each terminal penetrates in the front-rear direction. And a bottom surface provided with a notch for engaging with the shield.

Further, in order to hold a terminal group composed of a plurality of terminals in an insulating housing, for example, as described in Japanese Patent Application Laid-Open No. 2013-54844 (Patent Document 2), the arrangement of the plurality of terminals is determined. Then, there is a method of integrally molding with the housing by injecting resin into the mold.

JP 2011-233337 A JP 2013-54844 A

In recent years, the capacity of data processing devices mounted on electronic devices such as measuring devices and audio / video (AV) devices has been improved, and vast amounts of data can be processed in electronic devices. Electrical signals are sent and received at high speed via connectors. In order to appropriately transmit such a high-frequency electrical signal, a conventional connector having an insulating housing that holds one terminal group and the other terminal group facing each other includes a plurality of terminals included in each terminal group. By holding the terminals in the insulating housing so as to maintain a constant interval, it is possible to reduce disturbance such as impedance matching that may occur between a plurality of terminals, and to obtain desirable high-frequency characteristics.

However, in order to hold a plurality of terminals so as to maintain a constant interval with an insulating housing, as in the connector described in Japanese Patent No. 2011-233337 (Patent Document 1), a plurality of terminals are respectively connected to the housing. A plurality of holes for press-fitting along a plurality of formed grooves are provided in the back surface portion, or a plurality of terminals are formed with a jig or the like as described in JP 2013-54844 A (Patent Document 2). It is necessary to integrally mold by fixing in the mold and pouring the resin.

The method of press-fitting a plurality of terminals into the housing after molding the insulating housing is suitable for a connector having a structure in which a part of the plurality of terminals is covered with the housing, but a plurality of terminals included in one terminal group are included. Technically, there are many parts of the terminal that are not covered by the housing, and that part is susceptible to external influences, making it difficult to match the impedance of multiple terminals, and the high-frequency characteristics of the connector are likely to be disturbed. Problems can arise. Moreover, since the part exposed from a housing increases, a some terminal cannot fully be protected.

On the other hand, the method of integrally molding the housing so as to hold a plurality of terminals inside is suitable for a connector having a structure in which many portions of the plurality of terminals included in one terminal group are covered with the housing, Since there is a jig that fixes a plurality of terminals in place in the mold, a material such as synthetic resin is solidified around the jig during integral molding, and after removing the jig from the plurality of terminals, A hole by a jig is formed on the outer surface. Therefore, the portions of the plurality of terminals held by the housing that are exposed to the outside from the hole are easily affected by the outside, and as described above, the connector is inserted in the same manner as the method of inserting the plurality of terminals into the housing. This may cause a technical problem that the high-frequency characteristics of the device are likely to be disturbed.

By providing a plurality of holes generated by supporting the plurality of terminals respectively supported by the jig, the terminals are exposed on the outer surface of the housing formed by combining the first and second housing members on the mating surface. No holes, to provide a connector capable of reducing the influence on the high frequency characteristic from the outside.
