By the way, today, technological development for realization of IoT (Internet of Things) is in progress. For example, a technology for connecting various devices such as household electric devices, automobiles, industrial machines, and medical devices to the Internet, mounting sensors on these devices, and remotely monitoring or remotely operating these devices with an information terminal device. Is being developed. When mounting a sensor on a device, a connector for electrically connecting the device and the sensor is required. Increasing the size of the device by providing sensors and connectors on the device must be avoided. Therefore, it is desired that the sensor and the connector provided in the device are small in size.

There are the following problems in downsizing the connector. In the connector, a plurality of terminals are arranged at predetermined positions separated from each other, and each terminal is firmly supported in the connector housing so as to maintain the arrangement. When the size of the connector is reduced, the size of each terminal and the size of the connector housing are reduced, which may make it difficult to construct a structure that firmly supports a plurality of terminals in the connector housing.

Further, in the connector, it is necessary to secure the strength of each terminal so that the terminals of the connector are not damaged by repeated insertion and removal of the connectors. When the connector becomes smaller, the diameter of each terminal becomes smaller, which may make it difficult to secure the strength of each terminal.

The structure is such that the three contact receiving pins of the connector come into contact with each other. However, when the size of the connector is reduced, even if a mark is formed on the outer peripheral surface of the connector housing, the mark becomes small and it is difficult to confirm. Also, in the case of a small connector, it is not easy to pinch the connector by hand and rotate it in the circumferential direction finely.Therefore, when connecting the connectors, the rib of one connector is inserted into the groove of the other connector. As described above, it becomes difficult to perform the alignment.

(Manufacture of each connector)
The receptacle 11 is manufactured as follows, for example. First, the inner terminal 12, the intermediate terminal 18, and the outer terminal 24 are formed by pressing a metal plate material. Next, the support body 30 is formed around each of the connecting portions 15, 21, and 27 of the inner terminal 12, the intermediate terminal 18, and the outer terminal 24 by insert molding. Specifically, after arranging the connecting portions 15, 21, and 27 of the inner terminal 12, the intermediate terminal 18, and the outer terminal 24 in the mold, injecting a resin which is a non-conductive material into the mold. Thus, the support 30 is molded. With the above, the receptacle 11 is completed.

The method of manufacturing the plug body 42 of the plug 41 is as follows, for example. First, the inner terminal 43, the intermediate terminal 49, and the outer terminal 55 are formed by pressing a metal plate material. Next, the support body 65 is formed around the connecting portions 46, 52, 58 of the inner terminal 43, the intermediate terminal 49, and the outer terminal 55 by insert molding. Specifically, after arranging the connecting portions 46, 49, 55 of the inner terminal 43, the intermediate terminal 49 and the outer terminal 55 in the mold, injecting a resin which is a non-conductive material into the mold. Thus, the support body 65 is molded. With the above, the plug body 42 of the plug 41 is completed.

Here, FIG. 16 shows a mold piece 81 forming a part of a mold used for molding the support body 65 of the plug body 42. In the step of forming the support body 65, the mold piece 81 shown in FIG. 16 is provided inside the contact piece 44 of the inner terminal 43 formed in a cylindrical shape, inside the contact piece 44 of the inner terminal 43 arranged concentrically, and the intermediate terminal. 49 and the contact piece 50 of the intermediate terminal 49 and the contact piece 56 of the outer terminal 55 which are arranged concentrically.

The resin that tends to flow toward the tip side of the contact piece 50 is blocked by the two blocking protrusions 62 formed on the contact piece 50. As a result, it is possible to prevent the streak-shaped resin piece from being formed in the contact piece 50, such a resin piece is sandwiched between the contact piece 50 and the contact piece 19, and contact between both contact pieces is made. It is possible to prevent a defect from occurring. Similarly, when the resin is injected, inside the two grooves 85 formed in the cylindrical portion 84 inserted between the contact piece 50 of the intermediate terminal 49 and the contact piece 56 of the outer terminal 55 in the mold piece 81. The resin that tends to flow toward the tip side of the contact piece 56 is blocked by the two blocking protrusions 62 formed on the contact piece 56. As a result, it is possible to prevent the streak-shaped resin piece from being formed in the contact piece 56, such a resin piece is sandwiched between the contact piece 56 and the contact piece 25, and contact between both contact pieces is made. It is possible to prevent a defect from occurring.
