  The present invention relates to an electrical connector used in an electronic control device such as an automobile.

  In recent years, electrical signals transmitted to printed circuit boards for control mounted with electronic components and ICs (integrated circuits) incorporated in electrical devices of automobiles such as car navigation systems have been accelerated (increased in frequency). The printed circuit board pattern is also densely packed and densified. In general, a shielded wire for high frequency is used to transmit such a high-frequency electrical signal, but the electrical connector attached to the printed circuit board for connecting the shielded wire to the printed circuit board is also compatible with high frequency. There is a request.

  In such an electrical connector, as shown in FIG. 20, the connector socket 100 has a configuration in which the socket side electrical contact terminal 101 is attached to the socket side insulating housing 102 to form the socket side fitting portion 103. The side electrical contact terminal 101 includes a socket-side outer conductor 105 and a socket-side inner conductor 106, and the socket-side outer conductor 105 includes a shield outer cylinder 107. Then, on both side portions of the shield outer cylinder 107, spring-like shield contact terminals 108 are formed by cut and raised tongue pieces.

The plug-side inner conductor 113 and the plug-side outer conductor 114 are provided, and a space 116 between the inner surface portion of the plug-side fitting portion 115 and the plug-side outer conductor 114 formed by the front side portion of the plug-side insulating housing 111 is The shield contact terminal 108 that is displaced when the socket-side outer conductor 105 and the plug-side outer conductor 114 are electrically connected to each other is set large enough with a margin.

  Then, as shown in FIG. 21, the plug-side fitting portion 115 is fitted into the socket-side fitting portion 103, and the socket-side inner conductor 106 is brought into contact with the plug-side inner conductor 113, so that both the inner conductors 106, 113 are connected. Conduction is performed and both side wall portions of the plug-side outer conductor 114 are brought into contact with the shield contact terminal 108 of the socket-side outer conductor 105 to conduct both the outer conductors 105 and 114. At this conduction, the shield contact terminal The front side of 108 is displaced outward and inserted into the space 116 (see Patent Document 1).

  Some conventional electrical connectors include a board connector mounted on a printed circuit board and a cable connector as a mating connector for mating connection of the board connector. The board connector includes a dielectric having a receiving chamber for receiving the mating connector and a board connector-side outer conductor shell that accommodates the dielectric, and covers the outer periphery of the dielectric of the board connector-side outer conductor shell. The part is provided with a contact piece.

  Further, in the cable connector, insertion grooves are formed between the left and right side walls of the cable connector side outer conductor shell housed in the housing and the left and right side walls of the housing housing chamber. A contact piece of the board connector side outer conductor shell is inserted into the insertion groove.

  When the cable connector is fitted to the board connector, the board connector-side inner conductor is inserted into the cable connector-side inner conductor of the cable connector and is electrically connected by elastic contact, and is formed in the cable connector. When the contact piece of the board connector side outer conductor shell is inserted into the inserted groove and the contact piece elastically contacts the outer surface of the cable connector side outer conductor shell, the cable side outer conductor shell and the board side outer conductor shell Are electrically connected (see Patent Document 2).

  In the above-described conventional electrical connector, the space 116 between the inner surface portion of the plug-side fitting portion 115 and the plug-side outer conductor 114 is connected to the socket-side outer conductor 105 and the plug-side outer conductor 114. Since the shield contact terminal 108 that is displaced sometimes is set large enough so as not to interfere, it is suitable for electronic control devices such as automobiles that require a predetermined thickness for the housing from the standpoint of strength and twisting. In the electrical connector used, the width dimension of the plug-side fitting portion 115 is inevitably increased. For this reason, it is necessary to enlarge the socket-side fitting portion 103 into which the plug-side fitting portion 115 is fitted, the width dimension of the socket-side insulating housing 102 is increased, and the overall size of the electrical connector is increased. There was a problem of making miniaturization difficult.

Therefore, when the contact piece of the board connector side outer conductor shell is inserted into the insertion groove and the contact piece elastically contacts the outer surface of the cable connector side outer conductor shell, the contact piece opens outward. In order to displace, the insertion groove has to be set large enough with a margin so that the contact piece does not interfere with the left and right side walls of the housing chamber of the housing. The size of the electrical connector as a whole is increased, making it difficult to reduce the size of the electrical connector. In addition, the invitation of the tip of the contact piece is reduced so that the contact piece does not interfere with the left and right side walls of the housing chamber. As a result, there is a problem that buckling may occur during fitting.

Interference avoidance space is provided to avoid interference with shield contact terminals that sometimes displace, so the width dimension of the plug-side mating part can be reduced and the width dimension of the plug-side insulating housing can be reduced. Thus, the overall size of the connector plug is reduced, and the entire electrical connector can be reduced in size.

  Further, according to the electrical connector of the present invention, a concave groove is formed in the inner surface portion of the plug-side fitting portion facing the terminal contact portion of the plug-side outer conductor, and the space formed by the concave groove serves as an interference avoidance space. For this reason, the width dimension of the plug-side fitting portion is reduced, the width dimension of the plug-side insulating housing is reduced, the overall dimensions of the connector plug are reduced, and the electrical connector can be miniaturized.
