The connector 1A is a male type connector and is fitted into a female type connector (not shown). The female connector is provided in, for example, an electric connection box that supplies electric power from a battery or a signal from an ECU (Electronic Control Unit) to electrical components in a vehicle. The connector 1A may be used for connecting cables to each other. In the following description, for convenience of explanation, the side of the connector 1A to be inserted into the female connector in the length direction is the front, the direction opposite to the front side is the rear, and the right side in the width direction when viewed from the rear to the front is the right. When viewed from the rear to the front, the left side in the width direction is referred to as the left side, the upper side in the vertical direction is referred to as the upper side, and the lower side is referred to as the lower side.

The power lines 2A and 2B are conductor cables that supply the electric power supplied from the battery in the vehicle to the electrical components in the vehicle. The conductors of the power lines 2A and 2B are, for example, aluminum, copper, copper alloy, tin-plated wire, iron, nickel and the like.

The length of the housing 10A in the front-rear direction is shorter on the upper side than on the lower side. The terminal accommodating portion 101A has a space for accommodating the terminals 20A and 20B inside. The terminal accommodating portion 101A has an opening at the front, and has a partition portion 113 in the center in the width direction that partitions the space inside the terminal accommodating portion 101A to the left and right. In the terminal storage portion 101A, the terminal 20A is stored in the space on the right side of the partition portion 113 when viewed from the rear, and the terminal 20B is stored in the space on the left side of the partition portion 113 when viewed from the rear. The optical connector accommodating portion 102A is located below the terminal accommodating portion 101A and has a space for accommodating the optical connectors 30A and 30B inside. The front of the optical connector storage portion 102A is open. The cable accommodating portion 103A is located behind the optical connector accommodating portion 102A, and is a space for accommodating the power line 2A and 2B, the joint portion between the power line 2A and the terminal 20A, the joint portion between the power line 2B and the terminal 20B, and the signal lines 3A and 3B.

The cover 11A is a cover for closing the opening 112A, and is made of a synthetic resin. The cover 11A is fitted into the opening 112A and fixed to the housing 10A to close the opening 112A. The synthetic resin forming the cover 11A is, for example, polybutylene terephthalate, but is not limited to polybutylene terephthalate, and may be another synthetic resin.

When assembling the connector 1A, the terminals 20A and 20B and the optical connectors 30A and 30B are inserted into the internal space 111A from the opening 112A of the housing 10A in the insertion direction shown in FIG. Here, the optical connectors 30A and 30B are inserted into the optical connector storage unit 102A, and the terminals 20A and 20B are inserted into the terminal storage unit 101A. For the terminal accommodating portion 101A, the terminal 20A is inserted into the space on the right side of the partition portion 113 when viewed from the rear, and the terminal 20B is inserted into the space on the left side of the partition portion 113 when viewed from the rear.

FIG. 4 is a diagram showing a cross section of the housing 10A in a state where the terminals 20A and 20B and the optical connectors 30A and 30B are inserted into the internal space 111A. When the terminals 20A and 20B and the optical connectors 30A and 30B are inserted into the internal space 111A from the opening 112A of the housing 10A, the terminals 20A and 20B are bent, so that they are above the optical connectors 30A and 30B as shown in FIG. The terminals 20A and 20B are located, and the central axis of the connection portions 23A and 23B is deviated from the central axis at the insertion position of the power lines 2A and 2B into the housing 10A when viewed from the female connector to which the connection destination is connected. Next, when the cover 11A shown in FIG. 5 is fitted into the opening 112A from the rear of the housing 10A and the cover 11A is fixed to the housing 10A, the opening 112A is closed as shown in FIG.

According to the present embodiment, since the housing 10A houses the terminals 20A and 20B and the optical connectors 30A and 30B, the connector for storing the terminals 20A and 20B and the connector for storing the optical connectors 30A and 30B are separated from each other. Compared with the above, the power lines 2A and 2B and the signal lines 3A and 3B can be collectively connected to the electric connector box, and the man-hours for connection can be reduced. Further, since the terminals 20A and 20B are bent in the housing 10A and the power lines 2A and 2B are not bent inside the housing 10A, it is possible to prevent the power lines 2A and 2B from being damaged when assembling the connector 1A.

The connector 1A may be configured to have a fixing portion for fixing the terminals 20A and 20B in the housing 10A so that the terminals 20A and 20B do not move backward. FIG. 7 is a cross-sectional view showing an example of a configuration in which the terminals 20A and 20B are fixed in the housing 10A. The fixing portion 201A has, for example, a plate shape, and is integrally formed with the cover 11A in the horizontal direction. Although not shown in FIG. 7, the fixing portion 201A is also provided on the left side of the partition portion 113. The fixing portion 201A contacts the terminals 20A and 20B when the cover 11A is fitted into the opening 112A, and pushes the terminals 20A and 20B forward. According to the configuration shown in FIG. 7, even if the power lines 2A and 2B are pulled backward, the fixed portion 201A suppresses the movement of the terminals 20A and 20B to the rear, prevents the terminals 20A and 20B from coming out of the housing 10A, and prevents the power lines 20A and 20B from coming out of the housing 10A.

In this configuration, a portion of the fixing portion 204A penetrates the bush 40, and when the cover 11A is fitted into the opening 112A, the fixing portion 204A presses the bush 40 against the opening on the rear side of the optical connector housing portion 102A. Further, the optical connectors 30A and 30B are pushed forward in contact with the optical connectors 30A and 30B. Also in this configuration, since the opening on the rear side of the optical connector storage portion 102A is closed by the bush 40, it is possible to prevent dust and moisture from entering the cable storage portion 103A from the optical connector storage portion 102A. Further, even if the signal lines 3A and 3B are pulled backward, the movement of the optical connectors 30A and 30B to the rear is suppressed by the fixed portion 204A, and the optical connectors 30A and 30B are prevented from coming out of the housing 10A. The backward movement of 3B can be detained.

Further, in the configuration in which the connector 1A has the bush 40, as shown in FIG. 13, the fixture 50 formed in a concave shape is inserted into the hole penetrating the internal space 111A from the lower surface of the housing 10A, and the internal space 111A is inserted. The bush 40 and the optical connectors 30A and 30B may be fixed by the fixing tool 50 protruding from the above. In the configuration using the fixing tool 50, as shown in FIG. 14, the bushing 40 may be fixed by fitting the fixing tool 50 into a groove provided in the vertical direction in the bush 40.

Further, the connector 1A may have a configuration for preventing the power lines 2A and 2B and the signal lines 3A and 3B from moving in the front-rear direction.

The bush 41A has a groove in the vertical direction on the upper surface side. The cover 11A is fitted into the groove of the bush 41A and presses the bush 41A toward the housing 10A. According to the bush 41A, since the gap between the cover 11A and the housing 10A is closed, it is possible to prevent dust and moisture from entering the internal space 111A from the outside. Further, it is possible to suppress the movement of the power lines 2A and 2B and the signal lines 3A and 3B in the front-rear direction due to the friction with the bush 41A. The configuration having the bush 41A shown in FIG. 15 may be combined with the configuration of the embodiment or the configuration shown in FIGS. 8 to 14.
