Description

  The present invention relates to an electrical connector in which a mating connector is fitted or removed while connected to a signal processing integrated circuit mounted on a printed wiring board.

  In general, in various electrical equipment, a variety of signal transmission media such as fine coaxial cables and flexible wiring boards, or a pair of electrical connectors configured to fit and connect a pair of wiring boards (board-to-board) to each other are used. By doing so, electrical connection to the printed wiring board side is widely performed. In such a pair of electrical connectors, a plug connector (first connector) to which a signal transmission medium and a wiring board are connected and a receptacle connector (second connector) mounted on the printed wiring board are fitted. Thus, an electrical connection is made. For example, the coaxial electrical connector described in the following Patent Document 1 has an arrangement relationship in which an annular ground contact surrounds an outer side of a single core signal contact attached to an insulating housing. .

  One of the pair of electrical connectors as described above (receptacle connector) is usually mounted and used on a printed wiring board, and the signal processing having a necessary processing function is provided on the printed wiring board. An integrated circuit (IC / LSI chip) is mounted as a module card, for example. A receptacle connector is connected to the signal processing integrated circuit through a signal transmission conductive path and a ground ground conductive path formed on the printed wiring board. For example, in a mobile phone, a plug connector is connected to an antenna component via a coaxial cable, and the plug connector is fitted into a receptacle connector on a printed wiring board on which an antenna signal processing integrated circuit is mounted. Thus, the necessary antenna signal processing operation is executed.

  In particular, recent cellular phones and the like have a plurality of antenna configurations such as Wi-Fi, 3G, and Bluetooth. However, instead of preparing a module card for each antenna configuration, considering the productivity. If a standard module card with all antenna configurations is used and there is an antenna configuration that is not set in the specifications on the equipment side, the plug connector is not mated with the corresponding receptacle connector. Receptacle connectors may be used. However, such a plug connector non-engagement state with respect to the receptacle connector is basically not recognized by the signal processing integrated circuit (IC / LSI chip). Originally useless electric power continues to be supplied to the signal processing integrated circuit that is not fitted and is in a non-operating state. Therefore, conventionally, when the plug connector is removed, a switch circuit for stopping the power supply to the signal processing integrated circuit is separately prepared and mounted on the printed wiring board, or the signal processing integrated circuit is eliminated. Measures are taken. As a result, the number of mounted components and the number of work processes increases, which may cause a decrease in productivity.

The first and second contact parts are connected to each other when the mating connector is fitted. While the conductive state is maintained through a part of the connector, the first and second contact portions are electrically separated from each other and maintained in a non-conductive state when the mating connector is removed. ing.

  According to the electrical connector having such a configuration, the first and second contact portions are switched between conductive and non-conductive with the mating / unmating of the mating connector, and signals based on the switching are integrated in the signal processing. By receiving the circuit (IC / LSI chip), it is possible to perform necessary operations such as a switching operation for stopping power supply when the mating connector is removed.

  In this case, in the present invention, it is desirable that the first and second contact portions have connection legs connected to the signal processing integrated circuit.

  According to the electrical connector having such a configuration, connection to the signal processing integrated circuit is easily and reliably performed.

  Furthermore, in the present invention, the contact member is a ground contact formed in an annular shape, and the first and second contact portions divide the ground contact in a circumferential direction. It is possible to be made in the configuration.

  Furthermore, the signal processing integrated circuit according to the present invention has a power supply on / off switching operation corresponding to a signal generated based on switching between conduction and non-conduction between the first and second ground portions. Can be configured to perform.

  As described above, in the coaxial electrical connector according to the present invention, when the mating connector is fitted or removed, contact members to which a part of the mating connector is connected or separated are electrically separated from each other. The first and second contact portions are connected to the signal processing integrated circuit (IC / LSI chip) in a state, and the first and second contact portions are maintained in a conductive state when the mating connector is fitted.

An annular engagement portion 23c provided on a plug connector 20 as a mating connector, which will be described later, is brought into an elastic fitting state (see FIG. 9) in the annular engagement portion 13c of the ground contact 13.

  Here, the entire ground contact (annular contact member) 13 having the above-described configuration is composed of two first ground contact portions 13A and second ground contact portions 13B that are electrically separated from each other. Has been. That is, the above-described ground main body portion 13a is formed with two split slits 13a1 and 13a2 that divide the ground main body portion 13a in the circumferential direction so as to extend in the axial direction.

As a result, the signal processing integrated circuit (IC / LSI chip) 30 is disconnected. At the same time, the ground contact 13 of the plug connector 20 described later is separated from both the first ground contact portion 13A and the second ground contact portion 13B constituting the ground contact (annular contact member) 13 of the receptacle connector 10. As a result, the first ground contact portion 13A and the second ground contact portion 13B become non-conductive with each other, and the ground circuit of the signal processing integrated circuit 30 is disconnected. That is, with the removal of the plug connector 20, the ground circuit is cut off by the receptacle connector 10, and the cutting operation of the ground circuit is detected by the signal processing integrated circuit 30.

  As described above, the split slits 13a1 and 13a2 provided in the ground contact (annular contact member) 13 are along the annular axial direction (vertical direction) that is the direction in which the plug connector 20 is fitted and removed. Since the groove-shaped gap portion is provided, the ground main body portions 13a and 13a expand in the circumferential direction or the radial direction via the split slits 13a1 and 13a2 when the mating plug connector 20 is fitted and removed.
