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'' Conventionally, this type of connector is as shown in Fig. 4.
A long groove 12 is formed in the front surface 11a of the connector body 11 along its longitudinal direction, and a plurality of contact accommodating portions 13 and 14 are formed on both side wall surfaces of the long groove 12.
2 (in the figure, the direction perpendicular to the paper surface). Each contact housing section 13,
14 accommodates contacts 15 and 16, respectively, and the contacts 15 and 16 are biased inward from each other, and contact portions 17 and 18 are formed 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 contact 15, and after the wiring board is inserted into the long groove 12, the contact part 17 is inserted into the long groove 12 as shown by the contact 16. When it protrudes, it comes into pressure contact with the contacts 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, the long groove and the contact accommodating part are formed in the connector body, and the cam accommodating part is formed on the outside of each contact accommodating part, and the cam accommodating part A slider groove is formed that communicates with and extends in the arrangement direction. Contacts are accommodated in each of the contact accommodating portions,
Each contact has at least two folds, one end of which is led out as a terminal, and the other end of which is bent and extended in a direction perpendicular to the long groove to form a hook. Cams are housed in the cam housing portion so as to be movable in the vertical direction, and each of the cams is engaged with a hook portion of a contact. A slider is slidably arranged in the slider groove, and the slider has a diagonal groove, and the diagonal groove engages with each cam, and the cam moves in the vertical direction as the slider slides.

In this way, according to this invention, the cam is moved in the vertical direction by the sliding of the slider, and as a result, the contact part of the contact moves in and out of the long groove, making it easy to insert and remove the wiring board, and to ensure good contact. is obtained. Furthermore, since the connector is disposed laterally outside of the contacts of the slider, the height of the connector can be shortened.

"Embodiment" An embodiment of this invention is shown in FIGS. 1 to 3.
A long groove 12 is formed in the front surface 11a of the connector body 11 along its longitudinal direction, and a plurality of contact accommodating portions 13 and 14 are formed on both side wall surfaces of the long groove 12.
2 are arranged along the longitudinal direction. Contacts 15 and 16 are accommodated in each contact accommodation portion 13 and 14, respectively. The contacts 15 and 16 have two folds 15a and 1, respectively.
5b, 16a, 16b, the folding direction is perpendicular to the long groove 12, one end is led out from the rear as terminals 21, 22, respectively, and the other end is at a nearly right angle on the front side of the connector body 11. They are bent and extended outward from each other, and each bent portion serves as contact portions 17 and 18 that can enter and exit the long groove 12, and the bent extended ends are widened to serve as hook portions 31 and 32.

Cam accommodating portions 33 and 34 are provided on the front surface 1 of the connector body 11 on the outside of each connector accommodating portion 13 and 14.
It is formed toward the rear from 1a. Cam housing part 3
Cams 35 and 36 are housed in 3 and 34, respectively. cam 3
The front ends of the contacts 5 and 36 are hooked by the hook portions 31 and 32 of the contacts 15 and 16, and the outer surfaces of the hooked portions serve as cam surfaces 35a and 36a.
The cam surfaces 35a and 36a are tapered surfaces that protrude outward as they approach the rear from the front. cam 3
Engagement grooves 35b, 36b and engagement protrusions 35c, 36 for moving the cam up and down are provided on the outer surfaces of the rear parts of the parts 5 and 36.
c is formed.

A slider groove 3 communicating with the cam accommodating parts 33 and 34 on the outside of the cam accommodating parts 33 and 34, respectively.
7 and 38 are formed extending from one side of the connector body 11 in the respective arrangement directions of the cam housing portions 33 and 34. Sliders 41 and 42 are inserted into the slider grooves 37 and 38, respectively. slider 41,
Diagonal grooves 43 and 44 are formed on the inner surfaces of the cams 42, and the cam engaging protrusions 35c and 44 are formed in the diagonal grooves 43 and 44, respectively.
36c are respectively inserted and engaged. Diagonal groove 43, 4
4 is formed at the insertion ends of the sliders 41 and 42, as shown in FIG. 2, and both sides thereof are grooves parallel to the slider extension direction. Because of this structure, when the sliders 41, 42 are inserted into the connector body 11, the cams 35, 36 are pushed upward by engagement with the oblique grooves 43, 44, and the sliders 41, 42 are pushed upward.
2 from the connector body 11, the cams 35, 3
6 is pulled downward.

When inserting the wiring board (not shown) into the long groove 12 in the connector described above, the steps shown in FIGS.
The slider is pushed into the connector body 11, as shown by the slider 42 in the figure, and as a result, the cam protrudes upwardly, as shown by the cam 36, and its cam surface 36
At a, the hook portion 32 is displaced outward, and the contact portion 18 enters the contact accommodating portion 14 against the biasing force, so that the wiring board can be easily inserted into the long groove 12.

After the insertion, when the slider is pulled out from the connector main body 11 as shown in the slider 41, the cam retracts downward as shown in the cam 35, and the hook part faces the lower part of the cam surface as shown in the hook part 31, Due to the biasing force of the contact, the contact portion acts to enter into the long groove 12 as shown by the contact portion 17, and is pressed against the contact of the wiring board, thereby obtaining good contact.

When removing the wiring board from the long groove 12, slider 4
1 and 42 into the connector body 11, the contact portions of the contacts will be retracted into the contact accommodating portions, as described above, and the wiring board can be pulled out from the long grooves 12 with a weak force.

"Effects of the Invention" As described above, in this invention, the slider grooves 37 and 38 are provided side by side and outside the long groove 12, so that the height of the connector body 11 can be reduced. Although the height is low, the contacts 15 and 16 have at least two folds and have a so-called bellows structure, so that sufficient elastic force can be obtained and good contact can be obtained.
