[Problem that the idea aims to solve]

As mentioned above, conventionally, in order to branch a pair cable, it is necessary to separate it on the board. It is necessary to form a pattern for branching, and it is not possible to branch within the connector. Also, since there are a large number of connectors used for branching, it is troublesome to attach them to the board. Ta. Therefore, the problem with this invention is to branch out the pair cable within the connector. A receptacle connector for branching that can be easily attached to the board. The aim is to provide data. On the other hand, conventional branch connectors have a shell that covers the outer periphery of the connector. Because of this, it is easy for dust etc. to adhere to the shell, and this dust etc. There is also the risk of causing damage and making the mutual electrical connection unstable. Therefore, another problem with the present invention is to create a branching layer that does not damage the shell. An object of the present invention is to provide a receptacle connector and a plug connector.

[0005]

[Effect]

The receptacle connector according to claims 1 and 2 has two fitting holes, The fitting portions of the receptacle-side shells are arranged in these fitting holes, and , In this fitting hole, there is a wire branched from the lead-out terminal of the contact on the receptacle side. The contact part is protruding. Therefore, fit the mating plug connector into each mating hole. Then, the receptacle side shell and the plug side shell are connected, and the receptor The circuit side contact and the plug side contact are connected, and as a result, for example, the circuit board circuit The signal from the connector is split within the receptacle connector and sent to the two mating plug connectors. The signals are transmitted to the pair of cables connected to the respective connectors. On the other hand, the fitting part of the receptacle side shell is inserted into the fitting hole of the receptacle side shell. Because of this position, it is difficult for dust etc. to adhere to this mating part. The fitting part will not be damaged when connecting the connector. Further, in the case of the plug connector according to claim 3, the plug side shell is surrounded by a surrounding wall. Since the receptacle connector according to claim 2 is If used in combination, both the receptacle side shell and the plug side shell will be damaged. I never get bored.
