Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a connector into which a wiring board is inserted and removed.

``Prior Art'' As shown in FIG. 4, in a conventional connector of this type, a long groove 12 is formed along the longitudinal direction on the front surface 11a of a connector body 11, and a plurality of contact accommodating portions are formed on both side walls of the long groove 12. 13 and 14 are arranged in an array along the longitudinal direction of the long groove 12 (in the figure, the direction perpendicular to the paper surface). Each contact housing section 1
3 and 14 accommodate contacts 15 and 16, respectively, and the contacts 15 and 16 are biased inwardly, and the contact portions 17 and 18 are arranged from one end of the contact.
protrudes freely into and out of the long groove 12, and the contact 1
The other ends of the terminals 5 and 16 are led out as terminals 21 and 22.

A long groove is formed below the long groove 12 between the contacts 15 and 16, and a slider 23 is inserted into the long groove so as to be movable in the longitudinal direction of the long groove 12. The slider 23 is held on the contact body 11 by a bottom plate 24. Diagonal grooves 25 and 26 on both sides of the slider 23
cams 27 and 28 having protrusions inserted into oblique grooves 25 and 26 are interposed between the slider 23 and the contacts 15 and 16, respectively.

When the slider 23 is slid, the cams 27, 2
8 are moved up and down respectively, and when the cam 27 is pushed up as shown in the cam 27, the contact 15 is moved up and down by the cam 2.
When the cam 27 is pulled down as shown in the cam 28, the contact 16 is displaced toward the long groove 12 according to the biasing force, and the contact portion 18 is pushed into the long groove 13. Projects into 12. When inserting the connector part of the wiring board into the long groove 12, the contact part 17 is retracted as shown by the connector 15, and after the wiring board is inserted into the long groove 12, the contact part 1 is inserted as shown by the contact 16.
When 7 is made to protrude into the long groove 12, it comes into pressure contact with the contact on the wiring board.

As described above, in the conventional connector, since the slider 23 is located in the insertion direction of the wiring board, the height dimension of the connector becomes large.

"Means for Solving the Problem" According to this invention, each contact has at least two folded parts, and the direction in which the folded parts are formed is perpendicular to the longitudinal direction of the long groove. A terminal is led out, and the other end is extended in a direction perpendicular to the long groove to serve as a hook. The hook portion of each contact is engaged with an actuator extending in the longitudinal direction of the long groove, and the actuator is movable in a direction perpendicular to the long groove, and one side thereof has a serrated or trapezoidal toothed portion. A slider meshed with the serrated or trapezoidal teeth of the actuator is movable along the long groove.

When the slider is moved, the actuator moves in a direction perpendicular to the direction of movement of the slider due to engagement with the actuator at the serrated or trapezoidal part, and this movement causes the actuator to contact the long groove side of the contact through the hook part. The contact is displaced toward the accommodating portion, or conversely, the contact enters the long groove due to the biasing force.

"Embodiment" FIGS. 1 and 2 show an embodiment of this invention. A long groove 12 is formed in the front surface 11a of the connector body 11 along its longitudinal direction, and contact accommodating portions 13 and 14 are formed on both side walls of the long groove 12 at equal intervals.
are arranged in the direction of extension. Contacts 15 and 16 are accommodated in these contact accommodation portions 13 and 14, respectively. Contact 15, 16
are two folded parts 15a, 15b, 16, respectively.
a, 16b, the folding direction is perpendicular to the long groove 12, and one end is connected to the terminal 2.
1 and 22 are led out from the rear, and the other ends are bent and extended outward at a substantially right angle on the front side of the connector main body 11, and each bent portion has a contact portion 17 and 18 that can enter and exit the long groove 12. The bent extension ends are widened to form hook portions 31 and 32.

Actuators 33 and 34 hooked to these hook portions 31 and 32, respectively, are arranged parallel to the long groove 12. The actuators 33 and 34 are connected to guide walls 35 and 36 provided at both ends of the connector body 11.
This makes it possible to move freely in the direction perpendicular to the long groove 12.
A hook portion 3 is provided on the front surface of the actuators 33 and 34.
A shallow recess 37 having almost the same shape as 1 and 32,
38 is formed, and hook portions 3 are formed in the recesses 37 and 38.
1 and 32 are disposed, respectively, and the hook portions 31 and 32 are engaged with actuators 33 and 34, respectively. Trapezoidal tooth-shaped portions 41 and 42 are formed on the side surfaces of the actuators 33 and 34 on the long groove 12 side at the pitches of the contacts 15 and 16, respectively.

Actuators 33, 34 are provided between each arrangement of contacts 15, 16 and actuators 33, 34.
Sliders 43 and 44 that mesh with are arranged. The sliders 43 and 44 have trapezoidal teeth 45 and 46 that mesh with the trapezoidal teeth 41 and 42, and the sliders 43 and
44 is movable along the long groove 12, and guides 47 and 48 for its movement are formed at the end of the connector body 11, as shown in FIG.

The contacts 15 and 16 have contact portions 17 and 18
are each biased by itself such that they are located within the elongated grooves 12. When the slider 43 is pushed into the connector body 11 as shown in the left half of FIG.
The trapezoidal toothed portion 41 of the actuator 33 is now in a state where it can just mesh with the trapezoidal toothed portion 45 of the slider 43, and the actuator 33 is moved toward the long groove 12 by the biasing force of the contact 15, and the contact portion 17 is positioned within the long groove 12. Then, it is pressed into contact with the contact on the wiring board inserted into the long groove 12.

When the slider 44 is pulled in the direction of removal from the connector main body 11 as shown in the right half of FIG. The contact portions 18 of the contacts 16 enter the contact accommodating portions 14 due to the engagement between the hook portions 32 and the actuator 34, and the wiring board can be easily inserted into and removed from the long grooves 12.

As the number of contacts 15 and 16 increases, it becomes difficult to move the sliders 43 and 44 directly by hand. In this case, the pitch of the trapezoidal teeth may be lengthened, the slope of the slope may be made gentler, or a lever 51 for driving the sliders 43, 44 may be provided as shown in FIG. Serrations may be used instead of trapezoidal teeth. If the wiring board has contacts on only one side, the right or left half of FIG. 2 can be omitted accordingly.

"Effects of the Invention" In the connector of this invention described above, the sliders 43 and 44 are disposed laterally with respect to the long groove 12, so that the height of the connector can be reduced. Even if the height of the connector is lowered, contact 1
5 and 16 are folded and overlapped, that is, they have a bellows shape, so that large spring elasticity can be obtained.
