F) Connect to the connector. B. Conventional Technology Connectors for electrically connecting a film-like conductor, that is, a flexible printed circuit board, to another electrical element, such as an ordinary printed wiring board, have various types of non-insertion/extraction force connectors to facilitate insertion and removal. have been proposed, but in particular,
Figures 7 to 9 show conventional examples of compact, no-insertion-force connectors for flexible printed circuit boards. In these figures, figure A shows the state before the flexible printed circuit board 70 is attached,
Figure B shows the condition after installation. These force-free connectors shown are inserted into the cavity of the housing 979, 89 or 99 of the slider 78, 88 or 98t-connector in a direction parallel to the plane of the printed wiring board 71;
The inner wall of the slider engages with the spring contacts 77, 87, or 97 to ensure electrical connection and mechanical fixation between the substrate 70 and the contacts. C. Problems to be Solved by the Invention With the trend of miniaturization of electronic devices, the demand for ultra-miniaturization of connectors is also increasing. As is clear from FIGS. 7 to 9, in the above-mentioned conventional connector for a flexible printed circuit board with no insertion/extraction force, the ceiling of the connector and the ceiling of the slider overlap and slide, pressing the spring contacts. Because of the structure, lowering the overall height of the connector requires reducing the wall thickness of the ceiling of the housing and slider, and reducing the wall thickness of the ceiling deteriorates the mechanical strength of the connector. Due to contradictory reasons, there is a bottleneck in reducing the height of this type of connector. Therefore, it is an object of the present invention to provide a novel ultra-thin, no-insertion-forceless multi-pole connector for use in flexible printed circuit boards, which can further reduce the height dimension of the no-insertion-and-extraction-force connector. D. Means for Solving the Ill Problem The non-insertion/extraction force connector of the present invention has an end portion of a holding plate for pressing a flexible printed circuit board against a spring contact, and an end portion of an upper wall portion of an insulating housing of the connector. The present invention is characterized in that an engaging means is provided, and the operation direction for the presser plate to press the flexible printed circuit board is different from the operation direction for locking the presser plate to maintain the pressed state. E. Embodiment FIG. 1 is a perspective view of a 10-pole no-insertion/extraction-force connector assembly 1 according to an embodiment of the present invention. This shows that it is made up of three parts. FIG. 2 is a perspective view of the insulating housing 4 in which ten spring contacts 5 are incorporated, FIG. 3 is a side view of the unassembled housing 1 of FIG. 1,
FIG. 4 is a cross-sectional view of the assembly 1 shown in FIG. 1 taken along the line xx', and FIG. This is a perspective view for explaining the usage of the Hereinafter, even if the drawing numbers are different, the same parts are given the same reference numerals to avoid redundant explanations, and in order to make the present invention easier to understand, Based on the connector assembly 1 shown in Figure 1, the right side will be referred to as the front or front, the left side will be referred to as the rear or rear, the upper side will be referred to as the upper part, and the lower side will be referred to as the lower part. Referring to FIGS. 2 to 4, the insulating housing 4 of the present invention includes a bottom portion 20, a pair of side walls 21, and a top wall portion 22.
is an insulator block integrally molded with a plastic material, and includes a bottom part 20, a side wall part 21 and a top wall part 22.
It can be seen that it has a space 23 surrounded by. The bottom part 20 of the insulating housing 4 has ten inverted T-shaped contact receiving grooves 7 for inserting and fixing the spring contacts 51t.
is pierced. The spring contact 5 is bent into a U-shape as shown in the fourth figure, and one end thereof has a contact portion 6t-structure for electrically connecting with a conductor (not shown) of a flexible printed circuit board. The contact accommodating groove 7 is fixed by an appropriate means in such a manner that it protrudes upward from the upper surface 16 of the base 20. The other end of the spring contact 5 protrudes from the base 20 in the form of a solder tail 31t which is inserted into a through hole of a normal printed circuit board 49 (FIG. 4) and soldered. The bottom surface of the base 20 is the fourth
As shown in the figure, it is mounted on the surface of a printed circuit board 49. Referring to FIG. 4 to explain the top wall portion 22 of the insulating housing 4, it can be seen that the depth of the top wall portion 22 is less than half the depth of the bottom portion 20. That is, the rear end of the top wall 22 and the rear end of the bottom 20 are substantially aligned on a vertical plane and constitute the back of the insulating housing 4, but the front edge of the top wall 22 is aligned with the bottom 20. It is placed at a position considerably set back from the front edge, and the contact portion 6 of the spring contact 5 is exposed without being covered by the upper wall portion 22. Furthermore, as shown in FIG. 4 or 6, the upper wall portion 22
A convex arcuate portion 42 is provided at the front end of the lower surface over the entire width, and forms part of an engaging means for engaging with a curved portion 43 of the presser plate portion 12, which will be described later. A space defined by the lower surface of the top wall portion 22 and the upper surface of the bottom portion 20 is indicated by the reference numeral 23 in FIG. A pair of II+wall portions 21 for making the space 23 defined by the bottom portion 20 and the upper wall portion 22 into an ellipse will be explained with reference to FIGS. 1 and 2. The rear part of the side wall part 21 is substantially aligned with the rear ends of the bottom part 20 and the top wall part 22, and forms the back surface of the insulating housing 4. As can be seen from FIG. 2, the front end portion of the side wall portion 21 has a zigzag surface shape, and
2, a second vertical surface 19 provided at a position set back from the front end surface of the bottom portion 20 via a horizontal surface extending from the first vertical surface;
It consists of a third vertical surface 17 via a downward horizontal surface provided perpendicular to the vertical surface. A downward horizontal surface connecting the second vertical surface 19 and the third vertical surface 17 is named a lock surface 18. While the inner surface of the side wall portion 21 is a flat surface, the outer surface thereof is provided with a pair of platform portions 14 having an approximately semicircular cross-sectional shape and a pair of small protrusions 15 having a spherical surface. It is being done. These effects will be explained later. As can be understood from FIG. 1, the presser cover 8 has a plastic material integrally shaped like a pair of side plate parts 11 and a presser plate part 12 that connects the side plate parts. It is a character-shaped member. The holding plate portion 12 refers to the area of the holding cover 8 that presses the flexible printed circuit board, and therefore has a width that fits into the inner surfaces of the pair of side walls of the insulating housing 4. The cross-sectional shape of the holding plate portion 12 is as shown in FIG. 4, and the details of the structure will be explained below. Referring to FIG. 4, the upper surface e of the rear end of the presser plate part 12 has a concave curved part 43 cut in an arc shape.
The entire width of 2 is shaped. As shown in FIGS. 4 and 6, this engages with an arcuate portion 42 provided at the lower front portion of the upper wall portion 22 of the insulating housing 4 to form an engaging portion. Therefore, the curvature of the curved portion 43 is the same as that of the arcuate portion 42.
It is preferable that the curvature is greater than the curvature of the presser plate 12, and that the tip thereof terminates in a plane substantially parallel to the lower surface of the presser plate portion 12. The engaging portion configured as described above allows free movement of the presser plate portion 12 while maintaining the engagement between the front end portion of the upper wall portion 22 and the rear end portion of the presser plate portion 12. It can be tolerated. The detailed function of the engaging part will be explained later. As can be seen from the embodiments of FIGS. 5 and 6, when the connector is in use, the depth of the presser plate 12 is the same as that between the front green 51 of the presser plate 12 and the front edge 41 of the bottom 20 of the housing 4. are chosen so that they are aligned in almost the same vertical plane. Next, the side plate portion 11 of the presser cover 8 will be explained with reference to FIG. A pair of ears 9 are provided.
On the opposite side of the ear part 9, that is, inside the rear end of the side plate part 11, Ii! 1. A pair of depressions 32 (indicated by dotted lines in FIG. 3) widely surrounding the platform 14 of the green housing 4.
is provided. The combination of the recess 32 and the platform 14 provides a means for preventing the presser cover 8 from falling off easily from the insulating housing 4, and the curved portion 43 of the presser plate portion 12 extends along the arcuate portion 42. It has a structure that allows it to slide and change the angle or position of the presser cover 8 freely. Furthermore, a recess 33 (FIG. 3) is provided inside the side plate 11 surrounding the small protrusion 15 of the side wall 21, and cooperates with the protrusion 15 to prevent the side plate 11 from being forced downward. It is a holding means that resists external forces. It is shown in FIG. 4 that the lower front portion of the presser cover 8 is provided with a locking projection 44 for providing a locking means in cooperation with the locking surface 18.

．Since the front surface 46 of this locking protrusion 44 comes into contact with the second vertical surface 19 of the side wall portion 21, the presser cover 8 will not be pushed further diagonally than the state shown in FIG. 3 or 4. ．． Note that the inclination angle of the presser cover 8 is slightly larger than in FIGS. 3 and 4, and even if the surfaces 45 and 19 are disengaged, the combination of the platform l4 and the gap 32 will cause the presser cover 8 to The tip of the curved portion 43 is prevented from being pushed into the space 28 excessively or coming off from the engagement portion. In the illustrated embodiment, the presser plate portion 12 has the side plate portions 11 to form the presser cover 8, but it should be noted that the present invention can be practiced by omitting the side plate portions 11 and using only the presser plate portion 12. It is necessary to evoke it. In such an embodiment, it is necessary to provide appropriate locking means on the presser plate portion 12. Next, in order to explain the operation of the forceless insertion/extraction connector assembly 1 of the present invention, reference will first be made to FIG. 4. In the position of the presser cover shown in FIG. 4, that is, the presser cover 8 is inserted diagonally into the upper wall portion 22 of the insulating housing 4, and the contact portion 6 of the spring contact 5 and the lower surface of the presser plate portion 12 are aligned. When in the first position, the arcuate portion 42 and the curved portion 4 have a gap for inserting the end of the flexible printed circuit board between them.
Since a certain engaging part from 3 is not receiving any external force,
It is in a loosely engaged state. At this first position, the end portion 3 of the flexible printed circuit board 2 is passed through the space 2 through the above-mentioned gap.
3, and align the conductor at end 3 and the spring contact. Next, the front edge portion of the presser cover 8 is pressed downward (in the first direction) against the elastic repulsive force of the spring contact 5. At this time, as can be easily inferred from FIG. 4, which shows a cross-sectional view of the holding plate part 12, the engaging part made up of the arcuate part 42 and the curved part 43 is the fixing point, and the spring contact 5
A lever is constructed such that the contact portion 6 of the contact portion 6 and the pressing point of the presser cover 8 are moving points, so that the engaging portion strongly engages against the elastic force of the spring contact 5. Temporarily, the presser plate part 12
If the dimensions of the contact portion 6 and the engaging portions 42 and 43 are constant,
If you shorten the distance between the contact and Decide. When the presser cover 8 is pressed until it becomes almost parallel to the bottom 20 of the insulating housing 4, the locking protrusion 4 of the presser cover 8
4 is placed in a second position in which the upper surface of the insulating housing 4 is engageable with the locking surface 18 of the insulating housing 4. In this second position of the presser plate part 12 or the presser cover 8, the presser plate part 12 is pushed upward by the elastic repulsion force of the spring contact, so that the curved part 43 of the presser plate part 12 is bent over the arcuate part of the upper wall part 22. 42
As already mentioned, in this specification, this is referred to as strong engagement of the engaging portion. Therefore, when the presser plate part 12 is in the second position, (1) the engaging part is strongly engaged, and (11) the presser plate part 12 is connected to the upper wall part 22 through the engaging part.
This means that they are in a "butt juxtaposition" state where they are lined up almost on the same plane. Therefore,
In the “butt juxtaposition” state of the presser plate portion 12, the lower surface of the presser plate portion 12 and the lower surface of the upper wall portion 22 are placed in approximately the same plane,
This also means that the presser plate portion 12 is in a lockable position with the insulating housing 4. Next, place the presser cover 8 in the second position on the insulating housing 4.
When pressed in the horizontal direction (second direction), the engaging portions of the arcuate portion 42 and the curved portion 43 perform a sliding engagement (i.e., sliding while maintaining a strong engagement state). The presser cover 8 and the insulating housing 4 are locked by the locking means described above, that is, by the engagement of the locking protrusion 44 and the locking surface 18, and the presser cover 8 is placed in the third position.
At this time, it must be noted that the shape of the recess 32 surrounding the platform portion 14 is selected to have sufficient space so as not to impede the above-mentioned sliding engagement. FIG. 6 shows a cross-sectional view of the connector assembly in the third position where the insulating housing 4 and presser cover 8 are locked. The flexible printed circuit board is securely electrically connected to the contact part 6 of the spring contact 5 at the third position of the holding plate part 12, and is firmly fixed to the no-insertion/extraction-force connector assembly part 1. It is clear that the removal of the board 2 is carried out by reversing the previously described procedure, but the ears 9 of the presser cover 8 serve as a removal knob to facilitate the operation when moving the presser cover 8 from the third position. ．． Although one embodiment of the present invention has been described in detail above, the shape of the element that controls the engaging portion can take various other shapes, and the presser cover and locking means can be changed to other types. Since the changes and modifications are obvious to ordinary experts in this field, I will not explain them further. F. Effects of the Invention The connector of the present invention (1) has good workability because it can be used to slant the flexible printed circuit board, and especially in the case of a connector located in the central area of the printed wiring board, it is extremely easy to attach and remove the flexible printed circuit board; to be,
(II) Workability is good because the presser foot cover can be pressed from above with one touch, (lit ”) The part that guides the slider is unnecessary, so it can be made thinner, (h/) The presser plate part of the presser foot cover is made of aluminum. Since it is embedded in a part of the green housing body, it is possible to minimize the warping of the connector due to the elastic force of the spring contact. (V) When releasing the lock, the presser cover can be naturally held by pulling forward. The cover has the effect of being able to be opened.
