Since the holding portion 11b is held in the first housing portion 12c by press fitting, the contact 11 is held by the base plate portion 12a.

The mating connector 20 has a mating contact 21
Is held. The mating base portion 22 includes an insertion hole 22a into which the mating contact 21 is inserted so as to make one-to-one contact with the contact portion 11a, and a plurality of mating housing portions 22b connected to the insertion hole 22a and housing and holding the mating contact 21. have.

The mating contact 21 is accommodated in the mating accommodating portion 22b and is in one-to-one contact with the contact portion 11a.
a, a partner holding part 21b connected to one end of the partner contact part 21a and held in the partner accommodation part 20b, and a partner holding part 21
b has a mating connection portion 21c connected to one end side of the mating portion b and extending to the outside of the mating base portion 22.

The guide insulator 15 is formed with a positioning hole 15c for receiving the first engagement piece 13 and a wall surface of the positioning hole 15c so as to engage with the first hook portion 13a of the first engagement piece 13. A first engagement step 15d is formed.

On the inner wall surface of the engaging hole 13c, a second engaging step portion 13d is formed on the base plate portion 12a so that the second hook portion 16a of the second engaging piece 16 engages.

The base insulator 12 and the guide insulator 15, into which the contacts 11 are pressed and held, are locked to the base insulator 15 by a pair of first engagement pieces 13 integral with the base insulator 12. The first hook portion 13a of the first engagement piece 13 is formed on the first engagement step 1 formed on the guide insulator 15.
The engagement is made by being hooked on 5d.

Therefore, FIG. 1 shows arrows X, Y, Z
Direction, the connector 10 and the mating connector 2
0 indicates that the guide insulator 15 does not move in the fitting / removing direction Z, but can move freely on the surface X in the direction of arrow X and the surface Y in the direction Y perpendicular to the fitting direction.

Since the contact portion 11a of the contact 11 has a pin shape, the mating contact portion 21a of the mating contact 21 is made of a pair of spring pieces. A mating contact portion 21d is formed so as to sandwich the portion 11a therebetween.

As shown in FIG. 4, the base insulator 12 is mounted on a board (daughter board) 51 such as a printed circuit board. The substrate 11 has a contact 11
Is inserted and connected to the conductive portion of the substrate 51. The mating insulator 22 is mounted on a board (mother board) 55 such as a printed circuit board.
The connecting portion 21c of the mating contact 21 is inserted into the substrate 55 and connected to the conductive portion of the substrate 55.

An LSI is mounted on each of the substrates 51 and 55. In this stacked mounting structure, a large number of LSIs are mounted on the substrates 51 and 55, forming an electronic circuit package 59 having a stacked mounting structure. The electronic circuit package 59 is collectively assembled as a BWB (back wiring board)
81. The boards 51 and 55 are connected by a connector device consisting of the connector 10 and the mating connector 20, and the wiring between the LSIs is made short and a large-scale circuit is realized.

Next, the connector 10 and the mating connector 20
The operation of fitting the two will be described. First, the insulator 22 of the mating connector 20 is fitted into the groove 15 a of the guide insulator 12 of the connector 10. At this time, if the connector 10 and the mating connector 20 are displaced on the two axial directions X and Y perpendicular to the fitting direction, the guide insulator 15 moves so that the mating insulator 20 is fitted. With this operation, the floating portion 11c of the pin contact 11 moves following the direction in which the guide insulator 15 has moved since the contact 11 is in the first housing portion 12c of the guide insulator 15.

In a state before the contact 11 comes into contact with the mating contact 21, the guide insulator 15 and the mating insulator 22 start to be fitted. Therefore, the contact 11 can be brought to a regular position where the contact 11 can be fitted with the mating contact 21.

In this embodiment, the direction in which the contact 11 can be deformed is limited to the X-axis direction in FIG. 1, but it is of course possible to make the contact 11 deformable in the Y-axis direction.

The deformable floating portion 11c
Although only one location is provided, the floating portion 11c may be provided at several locations in the axial direction of the contact 11 to further facilitate deformation.

[0039]

According to the connector device having the floating function of the present invention, the displacement of the surface perpendicular to the fitting direction of the mating connector and the connector can be absorbed by the floating portion of the contact.

Also, the connector and the mating connector are biaxial surfaces perpendicular to the mating direction. If the connectors are misaligned, the guide insulator moves so as to fit the mating insulator, thereby absorbing the misalignment. Since it can be used, a plurality of units can be used in parallel without considering a positional deviation or the like.

Further, since the mating connector and the pins for positioning the connector are not required, the cost is reduced.

In addition, since the size of the contact is short, the distance between adjacent contacts is substantially constant, and the contact has a simple structure in which the cross-sectional shape of the contact can be easily adjusted, the matching of the characteristic impedance is facilitated. Suitable for transmitting ultra-high speed signals.

Further, when a pin-shaped contact is used for the connector, there is no contact failure such as the pin contact hitting the mating insulator of the mating connector or the contact buckling.

Further, since the deformable floating portion of the contact changes the thickness, the manufacturability of the contact and the assemblability of the connector device are improved.

Further, it is possible to collectively connect electronic circuit packages having a stacked mounting structure connected by a connector device having a floating function to a back wiring board.
