Indicates the connection state of the connector device.

First, referring to FIGS. 1 to 3, 6 and 7, the connector device has a connector 1 and a mating connector 2 which is fitted to the connector 1 and connected to each other.

The connector 1 includes a base 50 formed in a substantially rectangular box shape, an actuator 70 provided on the base 50 so as to be movable in a longitudinal direction, and a slider for moving the actuator 70. 80,
And a housing 60 provided on the actuator 70 and assembled to the base 50.

The base 50 holds a first conductive contact 30 used for signal transmission and a second conductive contact 40 used for grounding. Some of the first and second contacts 30 and 40 are driven by an actuator 70, as described below.

Each of the first and second contacts 30 and 40 includes a holding portion 31 held by the base 50, a first beam portion 32 extending from the holding portion 31 held by the base 50 in the fitting direction, and The first beam portion 32 has a second beam 33 that is folded back in the plate width direction at a leading end portion in the fitting direction and extends to the opposite side to the fitting direction. The distal end surface of the second beam 33 in the fitting direction serves as a contact portion 34 that comes into contact with the conductive mating contact 20 held by the mating connector 2.

In this embodiment, the first and second contacts 30 and 40 have thicker holding portions 31 and 41 held by the base 50, whereas the first and second contacts 30 and 40 have larger thicknesses. The second beam portions 31 and 32 are thin and eccentric to opposite sides.

A plurality of first and second contacts 30 and 40 are prepared, and are alternately arranged at intervals on the base 50 so that the plate thickness surface is parallel to the longitudinal direction of the connector 1. .

The actuator 70 penetrates the first and second contacts 30 and 40 at the position of the tip 35 of the second beam 33 in the fitting direction, and as shown in FIG. A groove 71 that opens in the direction is formed.

A plurality of contacts 20 sandwiched by the mating connector 2 with a dimension larger than the thickness of the contact portion 34 of the second beam portion 33 of the first and second contacts 30 and 40.
Is held. These contacts 20 are loosely fitted to the contact portions 34 of the second beam portion 33 and
Is moved in the longitudinal direction of the connector 1 to make an electrical connection.

As shown in FIGS. 1 and 4, the groove 71 of the actuator 70 is formed in the fitting direction through which the contact portion 34 penetrates.
The first and second contacts 30 and 40 have a penetrating portion 71a slightly larger in thickness than the plate thickness of the first and second contacts 30 and 40, and a wide portion 71b which is wider than the penetrating portion 71a in a tapered shape in an anti-fitting direction.

The grooves 71 of the actuator 70 are provided at the tips 35 and 45 of the second beam portions 32 of the contacts 30 and 40.
71a is set to have a width slightly larger than the plate thickness of the contacts 30 and 40, and expands in a tapered shape in the anti-fitting direction downward in the figure, and is connected to the wide portion 71b. Further, an invitation 71c for the contacts 30 and 40 during assembly is provided below this.

First and second contacts 30 and 40
Are installed adjacent to each other in the longitudinal direction of the connector 1, the first beam portions 32 overlap each other with a gap in the longitudinal direction of the connector, and the second beam portions 33 are in opposite directions in the plate width direction. It is configured to be folded back.

In the actuator 70, as shown in FIG. 6, a relief groove 72 connected in the longitudinal direction is formed at a portion where the first beam portion 32 of the first and second contacts 30 and 40 is located. The two ends of the connector 1 are connected to each other in the left-right direction in the width direction of the connector 1 to be integrally formed. In this embodiment, the actuator 70 is formed in a box shape.

The housing 60 is engaged with the base 50 and covers a tip portion including the contact portion 34 in the fitting direction of the first and second contacts 30 and 40, and the contact portion 34 extends in the longitudinal direction of the connector 1. In addition to guiding, the mating position of the mating connector 2 with the insulator 10 is adjusted,
The contact 20 is received.

The mating contact 20 is formed in the shape of a tuning fork, and a slit portion having a small gap is provided at two places in the fitting direction, and contacts 21 and 22 are formed in this slit portion.

The connector 1 is assembled by assembling the contacts 30 and 40 into the base 50 as shown in FIG.
From above, the actuator 70 and the first
The link 90, the second link 100, and the slider 80 are assembled.

The movement of the actuator 70 is performed by a toggle mechanism using the first link 90, the second link 100, and the slider 80, but other methods may be used.

The connector 1 assembled in this way is shown in FIG.
It will be better understood with reference to the drawings shown in FIGS. The connector 1 is shown in FIGS. 1, 4, 6 and 11
The first and second contacts 3 are mounted on the substrate 120 shown in FIG.
After the terminal portions 0 and 40 are inserted, they are connected by solder.

FIGS. 12 and 13 show how the mating connector 2 is assembled. The partner contact 20 is held in the partner insulator 10 by, for example, press fitting. This mating connector 12 will be better understood with reference to FIGS.

As shown in FIGS. 1, 4, 6 and 17, the mating connector 2 is mounted on the mating board 110, and the mating contact 20 is inserted into a through hole formed in the mating board 110.

That is, the connector 1 and the mating connector 2 can be connected so that the board 120 and the mating board 110 are perpendicular when they are fitted to each other.

Next, the operation of the open state and the connected state of the connector device will be described. As described above, FIGS. 1 and 2 show the open state, in which the mating connector 2 can be inserted into and removed from the connector 1 with no insertion force or a very small force.

When the mating connector 2 is fitted into the housing 60 of the connector 1 in the state shown in FIGS. 1 and 2, and the slider 80 is moved in the directions shown in FIGS.
The actuator 70 is moved by the toggle mechanism including the links 90 and 100, and the state shown in FIGS. 4, 5 and 6 is obtained.

Referring to FIG. 4, when the connector 1 is connected,
Although the tip 35 of the second beam portion 33 is also inclined in the through portion 71a, the tip 35 of the second beam portion 33 minimizes backlash in the longitudinal direction of the connector 1 due to the configuration of the lower taper and the wide portion 71b. Thus, the amount of movement of the actuator 70 for making the connection or the open state can be minimized.

In FIG. 4, the right portion of the penetrating portion 71a is the second portion.
Push the tip 35 of the beam 33 to the left, and press the second beam 33
Contact surface 34 is slanted in the slit of the mating contact 20 and contacts the contacts 21 and 22.

At this time, the force by which the right side of the penetrating portion 71a presses the tip 35 of the second beam portion 33 with respect to the contact force is reduced to a value corresponding to the leverage ratio.

Since the mating contacts 20 connected to the first and second contacts 30 and 40 are spaced apart in the left-right direction in FIG. 6, the longitudinal direction of the connector 1 of the first and second contacts 30 and 40 is long. The distance in the direction can be set freely.

Therefore, even if the widths of the first beam portions 32 and 42 are narrow, the distance between the first beam portions 32 in the longitudinal direction of the connector 1 is reduced so that the characteristic impedance between the first beam portions 32 becomes an appropriate value. Can be set.

In the embodiment, the first and second contacts 30
And 40, but they may be arranged in four or more rows in the horizontal direction of FIG.

[0039]

As described above, according to the connector device of the present invention, since the relative movement between contacts is not required, the mounting state is limited even when applied to a connector for connecting a board to a board. A connector device free of the above is obtained.

Also, there is little backlash in the direction of movement of the actuator between the groove of the actuator and the contact, and the invitation at the time of assembling the contact from the side opposite the fitting direction of the actuator can be increased.

Further, the degree of freedom in setting the distance between adjacent contacts in the first beam portion is increased.

In addition, a connector device with good assemblability can be obtained in which the movement of the actuator at the time of driving the connection of the connector is minimized.

Furthermore, the characteristic impedance between the first beam portions can be set to an appropriate value by reducing the length of the first beam portion facing the connector in the longitudinal direction, and a connector with easy matching of the characteristic impedance can be obtained.
