Reference numeral 7 denotes a female electrical connector housed in the socket body 1, as shown in FIG.
And an inverted L-shaped connecting portion 10 connecting the two. The contact portion 8 is a vertical substrate portion 11.
And a contact piece 12 having an elastic force extending obliquely downward from the upper end of the base portion 11, and a locking claw 13 is provided below the substrate portion 11. Further, the terminal portion 9 is formed in a strip shape of a predetermined length, and the upper half 9A is formed narrower than the lower half 9B from the center thereof so as to be elastically deformable in the front-rear direction (the contact portion 8 direction). A locking claw 14 is provided on both upper sides of the lower half 9B. Further, the connecting portion 1
0 is connected to one side edge of the substrate portion 11 of the contact portion 8, and the upper end of the connection portion 10 is connected to one side edge of the upper end of the terminal portion 9 to integrate the contact portion 8 and the terminal portion 9. ing.

The contact portion 8 of the female electrical connector 7
Are fixed to the movable socket housing part 2 by locking claws 13 of the substrate part 11, and the contact pieces 12 are exposed in the plug insertion recesses 2A of the movable socket housing part 2, and the female electrical connector 7 The terminal portion 8 is fixed to the terminal fixed housing portion 3 by a locking portion 14, and the lower portion of the lower half 9 </ b> B protrudes from the bottom surface of the terminal fixed housing portion 3.
The printed circuit board 15 is provided with a locking long hole 16 into which the hook 5 of the movable socket housing 2 is inserted and locked, and a positioning pin 6 is inserted. Slot 16 for the movable socket housing 2
Is formed in an elongated hole so as to be movable in the direction of the terminal fixing housing portion 3.

Therefore, as shown in FIG. 6, the movable socket housing portion 2 is movably engaged with the printed board 15 by the hook 5 and the terminal fixed housing portion 3 is formed on the copper foil pattern on the back surface of the printed board 15 by a female. The terminal portion 9 of the electric connector 7 is fixed by soldering 17. At this time, the hook 5 and the positioning pin 6 of the movable socket housing part 2 are located at the center of the locking long hole 16 formed in the printed circuit board 15 as shown in FIG. The portion 2 can be moved in the direction (approaching direction) or the opposite direction (separating direction) of the terminal fixing housing portion 3.

Further, a male electrical contact 19 for electrically connecting to the contact piece 12 of the female electrical connector 7 fixed to the movable socket housing portion 2 is provided on the front surface of the plug 18. The width of the male electrical contact 19 is wider than the width of the contact piece 12 of the female electrical connector 7.

Therefore, the plug 18 is inserted into the plug insertion recess 2A of the movable socket housing 2 from above, and
The two electric connectors 7, 19 are electrically connected. At this time, when the plug 18 is inserted into the movable socket housing portion 2 at the position shown in FIG. 6 in a state where the movable socket housing portion 2 is displaced in the direction of the terminal fixed housing portion 3, FIG.

On the other hand, when the plug 18 is inserted into the movable socket housing 2 at the position shown in FIG. 6 in a state where the movable socket housing 2 is displaced in the opposite direction to the terminal fixed housing 3. As shown in FIG. 8, the movable socket housing part 2 is provided with an elastic deformation of the elastic connecting plate 4 and the upper half 9A of the terminal part 9 of the female electrical connector 7.
Is moved away from the terminal fixing housing part 3 by the elastic deformation of
It is possible to prevent breakage of the electrical connectors 7 and 19, peeling of the soldering 17 and the like, and maintain a good electrical connection state at all times.

The length of the plug insertion recess 2A in the width direction of the movable socket housing portion 2 is formed larger than the length of the plug 18 in the width direction, so that the plug 18 can move in the width direction within the recess 2A. Therefore, the displacement of the plug 18 in the width direction with respect to the movable socket housing portion 2 is also eliminated. In this case, since the width of the male electrical connector 19 is considerably wider than the width of the female electrical connector 7, there is no problem in electrical connection.

[0017]

As described above, the printed circuit board connector according to the present invention comprises a movable socket housing for accommodating a contact portion of a female electrical connector with a plug, and a terminal portion of the female electrical connector. The terminal fixing housing part to be stored
The two housing portions are connected to each other by a pair of left and right substantially crank-shaped elastic connecting plates having one ends fixed to both side end portions, and the two housing portions are movable in the direction of contact and separation with each other by elastic deformation of the elastic connecting plates. Because the relative positional relationship between the movable socket housing and the plug is shifted in the direction toward the terminal fixed housing or in the opposite direction, even if the plug is fitted into the movable socket housing, Due to the elastic deformation of the connecting plate, the movable socket housing approaches the direction of the terminal fixed housing or moves parallel to the direction away from the terminal fixed housing, thereby absorbing unnecessary external force due to the displacement. Therefore, adverse effects on the female electrical connector of the movable socket housing portion, the male electrical connector of the plug, and the like are reduced, and a good electrical connection state can be maintained at all times. Also,
A hook is vertically provided at the bottom of the movable socket housing part, and the hook is formed so as to be inserted into a long slot for locking in the direction of the terminal fixing housing part formed on the printed circuit board, so that the movable socket housing part is formed. This movement is guided by the locking long hole, and can be moved smoothly. Further, the length of the plug insertion recess in the width direction of the movable socket housing portion is formed to be larger than the length in the width direction of the plug, and the plug is formed so as to be movable in the plug insertion recess. Even when the plug is fitted into the movable socket housing with the relative positional relationship between the housing part and the plug shifted in the width direction, the plug moves in the width direction within the plug insertion recess,
There are various effects that unnecessary external force due to the displacement can be absorbed.
