JP-A-11-168168

  When electrical components are mounted on a circuit board using a connector device composed of two connectors each having a plurality of contact terminals, the positional relationship between the male contact terminals and the female contact terminals is correct. It is necessary to work to match the two connectors. The greater the number of contact terminals, the more cumbersome this work becomes.

  An object of the present invention is to provide an electrical component mounting structure and a connector adapter that can facilitate connection work of a connector device.

  The electrical component mounting structure to be improved by the present invention includes a first connector having a plurality of first contact terminals in a first housing, and a plurality of first contact terminals in a second housing, respectively. And a second connector having a plurality of second contact terminals to be fitted and connected, and using a connector device in which one or more guide pins are provided in the first housing, the electrical component is placed on one side of the circuit board. To be mounted on the surface. In the present invention, the second housing of the second connector is disposed on one surface of the circuit board. A connector adapter having one or more guide pin fitting holes into which one or more guide pins are fitted is inserted into the one or more guide pin fitting holes. It arrange | positions on one surface of a circuit board so that the positional relationship which a 1st contact terminal contacts the several 2nd contact terminal may be formed between a 1st connector and a 2nd connector.

  If such a connector adapter is arranged on one side of the circuit board together with the second connector, the one or more guide pins become one or more guide pins when the first connector is connected to the second connector. In the process of being inserted into the fitting hole, the plurality of first contact terminals are appropriately fitted and connected to the second contact terminal. Therefore, according to the present invention, connection work of the connector device is facilitated.

  The length of the guide pin provided in the first connector to be used may be longer than the length of the guide pin fitting hole. In such a case, if one or more guide pin fitting holes are through holes, one or more extending through holes communicating with the guide pin fitting holes may be formed in the circuit board. In this way, after the one or more guide pins pass through the one or more guide pin fitting holes, they are fitted into the one or more extension through holes. Therefore, the present invention can be applied even when the length of the guide pin is long.

  Even when there is only one guide pin, positioning is possible if the cross-sectional shape of the guide pin is a square and the cross-sectional shape of the guide pin fitting hole is a square.

  When off-the-shelf products are used as the first and second connectors, the connector adapter is configured separately from the second connector. In many existing connectors, two guide pins are arranged on both sides of a row in which a plurality of contact terminals are arranged. Therefore, the connector adapter includes a plurality of adapter main bodies having housing fitting holes into which the second housing is fitted, and a plurality of locked portions provided integrally with the adapter main body and provided on the circuit board. It is preferable to have a configuration including a locking portion. And two guide pin fitting holes are respectively formed in a pair of opposite ends of the adapter body. In this way, when the connector adapter is arranged on the one surface of the circuit board together with the ready-made second connector, the positional relationship between the second connector and the connector adapter is determined. And since two guide pin fitting holes are formed in a pair of edge part which an adapter main body opposes, it can respond to the existing connector with a guide pin. The connector adapter can be easily attached to the circuit board by locking the plurality of locking portions provided on the connector adapter to the plurality of locked portions provided on the circuit board.

  The plurality of locked portions are constituted by a plurality of through holes formed in the circuit board, and the plurality of locking portions are extended portions that respectively penetrate the through holes, and the other surface of the circuit board that protrudes from the through holes. It is possible to provide a structure including a hook portion that is locked to the hook. If it does in this way, the adapter for connectors can be easily attached to a circuit board only by inserting a plurality of locking parts in a plurality of locked parts (through hole) provided in a circuit board.

  Preferably, a positioning pin for positioning the connector adapter with respect to the circuit board is provided on one of the adapter body and the circuit board, and a positioning pin fitting hole is provided on the other of the adapter body and the circuit board. If it does in this way, the position with respect to the circuit board of the adapter for connectors can be defined correctly.

  The connector adapter applied to the existing connector can be composed of two separate adapters arranged adjacent to a pair of opposing ends of the second housing. In this case, the separation adapter includes a separation adapter main body provided with a guide pin fitting hole, and a plurality of locking portions that are provided integrally with the separation adapter main body and locked to the locked portions provided on the circuit board. It can be configured as provided. If such a separation adapter is used, it can be used for various types of first and second connectors having different shapes and dimensions. In addition, the area occupied by the connector adapter can be further reduced.

  The locked portion provided for the separation adapter is constituted by a through hole, and the plurality of locking portions surrounds the periphery of the guide pin fitting hole and is fitted with a plurality of extending portions fitted into one through hole. A hook portion protruding from the hole and locked to the other surface of the circuit board can be provided. Also in this case, the connector adapter can be easily attached to the circuit board simply by inserting the plurality of locking parts into one locking part (through hole) provided on the circuit board.

  When the second connector is manufactured as a dedicated product, the connector adapter is composed of two separate adapters provided integrally with a pair of opposing ends of the second housing, and the two separate adapters are guided by the two separate adapters. A pin fitting hole may be formed. If it does in this way, the adapter for connectors and the 2nd connector will be integrated, and the number of parts of the attachment structure of an electrical component can be decreased.

  The adapter main body of the connector adapter used in the electrical component mounting structure can be configured such that the outline viewed from the plane is rectangular. The plurality of locking portions include a pair of first locking portions and a pair of second locking portions, and the extending portions of the pair of first locking portions and the pair of second locking portions. The length of the stop portion is different from that of the extended portion. The first imaginary line passing through the pair of first locking parts and the second imaginary line passing through the pair of second locking parts intersect so that the pair of first locking parts and the pair of second The position of the locking part is determined. If it does in this way, the adapter for connectors can be attached to two kinds of circuit boards from which thickness differs. A pair of locking portions with a short extension portion is locked to a thin circuit board, and a pair of locking portions with a long extension portion is locked to a thick circuit board.

  When the connector adapter is composed of two or more separation adapters, the hook portion is fitted with through holes provided in two types of circuit boards having different thicknesses, and can be locked to the other surface. Steps can be formed. In this way, the separation adapter can be attached to two types of circuit boards having different thicknesses.
