In order to separate from the sheet member 51 and adhere to the frame with the tape, an area for adhesion is required for the frame, and in order to increase the adhesion to a certain extent, the area must be larger than that. .

SUMMARY OF THE INVENTION In view of the above, it is an object of the present invention to provide a connector device having a compression connector that can accurately and firmly hold a connector on a frame even if it is small.

[0010]

SUMMARY OF THE INVENTION An electrical connector device according to the present invention includes a connector in which a plurality of conductive compression contacts are arranged on an insulating sheet member, and a frame for supporting an edge of the sheet member. Further, the frame includes a supporting means for supporting the sheet member at a predetermined position on the supporting surface.

In this connector device, in the present invention, the support means is provided as a protruding column so as to protrude from the support surface of the frame, and the seat member has an engaging hole at the predetermined position for engaging the protruding column. , At least one of the protruding pillar and the edge of the engaging hole is elastically deformable in one specific direction in a plane parallel to the support surface as compared with the other direction.

Therefore, when the engagement hole of the sheet member is engaged with the projection of the frame by engagement, at least one of the edge of the engagement hole and the projection is elastically deformed in one specific direction more than in the other direction. Since it is possible, the fitting engagement is performed under the elastic deformation in the specific one direction, so that when the elastic deformation is released after the engagement, the edge of the engaging hole is in close contact with the protruding column. As a result, the engagement position accuracy is improved. In the other direction, the protruding column only guides the engagement hole, which can also be in close contact, so that the engagement position accuracy can be increased. In addition, since the protruding columns have high strength, even if they are small and are provided in close proximity to the opening of the frame, their functions can be sufficiently exhibited, and the entire frame can be downsized.

In the present invention, it is preferable that a plurality of sets of the protruding pillars and the engagement holes are provided, and at least one set has a direction different from the other set as a specific one direction. In the other direction, when there is a gap between the edge of the engaging hole and the protruding column, the protruding column cannot be guided by one set of the protruding column and the engaging hole. With the engagement holes, different directions can be set as one specific direction, and positional accuracy can be obtained in all directions.

In the present invention, in the case where elastic deformation in a specific one direction is caused to occur in the projection, the projection has a form having two flexible columns facing each other in a specific direction. be able to. The two flexible struts contact the diametrically opposite edges of the engagement hole of the sheet member, and undergo elastic deformation so as to approach toward the center of the engagement hole for engagement.
When the protruding column has two flexible columns opposing each other in one specific direction, the protruding column may additionally have two rigid columns opposing each other in another direction. it can. By doing so, at the time of engagement, the rigid support is in close contact with the edge of the engagement hole, and guides the sheet member in a state of high positional accuracy.

The flexible strut has a locking claw that locks to an edge of the engaging hole when it returns to its original shape after elastically deforming and penetrating into the engaging hole of the sheet member, thereby preventing the flexible post from coming off. It is preferable that this can be achieved. In this case, the locking claw may be provided at a position where a floating gap of the sheet member is formed between the locking claw and the sheet member.

In the present invention, elastic deformation in one specific direction may be caused in the sheet member.
In this case, the sheet member may have a resilient elasticity, and may have a form in which a notch is formed in which the edge of the engagement hole is located in a direction orthogonal to the specific one direction.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 to FIG.
An embodiment of the present invention will be described based on the above.

<First Embodiment> In FIG. 1, a frame 1 has a projecting column 3 for mounting a seat member 2. The frame 1 is made of an insulating material and has a window-like opening for locating a number of compression contacts provided on a sheet member, similarly to the conventional frame shown in FIG. However, this is different from that of FIG. 6 in that a plurality of the columns 3 are provided near the opening of the frame (the entire frame is not shown). In FIG. 6, the sheet member is attached at a predetermined position with an adhesive tape. However, in the present embodiment, the attachment is performed by engaging the engaging hole of the sheet member 2 with the protruding post 3. .

In this embodiment, the protruding column 3 of the frame 1 has two flexible columns 4. The two flexible struts 4 include an annular groove 5 extending deeply to an intermediate position in the thickness direction (the vertical direction in FIG. 1B) of the frame 1 and a gap extending in the diameter direction of the annular groove 5 and penetrating in the thickness direction. 6 and has a crescent-shaped cross section as shown in FIG. The flexible struts 4 protrude above the upper surface (support surface) 1A of the frame 1, and locking claws 7 protruding in the radial direction are formed at two positions in the circumferential direction at the top thereof. As described above, the flexible strut 4 formed long in the height direction by the deep annular groove 5 has elasticity in the direction to narrow the gap 6 and is flexible in the same direction. The locking claw 7 has a tapered surface 7A on the outer periphery of the upper surface, and the gap between the lower surface 7B of the locking claw 7A and the support surface 1A is set slightly larger than the thickness of the sheet member 2.

On the other hand, a number of compression contacts (not shown)
A circular engaging hole 8 is formed at a position corresponding to the above-mentioned protruding column 3 so that the insulating sheet member 2 holding the sheet is held at a predetermined position by the frame 1. The inner diameter of the engagement hole 8 is substantially the same as the outer diameter of the lower portion of the two flexible columns 4 below the locking claw 7. In the drawing, a gap is shown between the engagement hole 8 and the flexible support column 4 in an exaggerated manner. However, in order to improve the positional accuracy between the two, there is not much gap but almost close contact. . In this manner, the engagement hole 8 is formed with high accuracy in both its position and diameter in conformity with the position and the outer diameter of the protruding column 3.

In this embodiment, the sheet member 2 is mounted on the support surface 1A of the frame 1 in the following manner. The seat member 2 is raised above a predetermined position of the frame 1, and is positioned so that the engagement holes 8 of the seat member 2 substantially coincide with the columns 3. The sheet member 2 is fitted to the protruding column 3 (flexible column 4) from above. The seat member 2 has its engaging holes 8 guided by the tapered surfaces 7A of the two flexible struts 4 and presses the locking claws 7 inwardly to generate elastic bending in the same direction. It moves downward while being elastically deformed so as to narrow the gap between the hooks, gets over the locking claw 7, and fits between the lower surface 7B of the locking claw 7 and the support surface 1A of the frame 1. At that time, the flexible support column 4 does not receive the force from the sheet member 2, so that it recovers its original shape and the locking claw 7 prevents the sheet member 2 from coming off as shown in FIG. The locking hole 8 of the seat member 2 and the projection 3 of the frame 1
Since the positions at which they are provided and the hole diameter and the outer diameter are made with high precision, the edge of the locking hole 8 is
By contacting the outer diameter of the sheet member 2, the position of the sheet member 2 in the direction X is held at a predetermined position with high accuracy. In the direction Y orthogonal to the direction X, since the locking hole 8 is in contact with the arc-shaped outer peripheral surface of the flexible column 4, this is also positioned with high precision. Thus, the connector is obtained by accurately attaching the sheet member holding a large number of compressed contacts to the predetermined position of the frame.

<Second Embodiment> In the previous embodiment, the projection 3
Although the second embodiment shown in FIG. 2 is characterized by having two rigid struts 9 in addition to the two flexible struts 4, the second embodiment shown in FIG.

As can be seen in FIG. 2, the flexible strut 4 and the rigid strut 9 are both provided in diametrically opposed pairs, and are located at right angles to each other.

The flexible strut 4 is different from that of FIG.
It is the same in that it has the locking claw 7, but as shown in FIG. 2A, the cross-sectional shape is not a crescent shape as in FIG. 1 but a substantially square shape. However, the outer peripheral surface has an arc shape. The flexible strut 4 is formed higher by a deep groove 5A and a gap 6 corresponding to the annular slit in FIG. 1, and has elasticity and flexibility in a direction to narrow the gap 6.

On the other hand, the rigid support 9 has an outer shape having a crescent-shaped cross section (see FIG. 2A), and does not have a locking claw like the flexible support 4. Although an extremely shallow groove 5B is formed on the outer periphery of the rigid support 9, the rigid support 9 does not become as high as the flexible support 4 and thus has no flexibility.

The outer peripheral surface of the flexible column 4 below the locking pawl 7 and the outer peripheral surface of the rigid column 9 are located on the same circle.

In this embodiment, when the sheet member 2 is engaged with the protruding pillar 3 in the manner shown in FIG. 1, the edge of the engaging hole 8 of the sheet member 2 is tapered by the engaging claw 7. While being guided by the surface 7 </ b> A, as shown in FIG. 1, it fits below the engagement claw 7, and the engagement piece 7 prevents the detachment. As described above, the engagement hole is provided so that the sheet member 2 is supported by the support surface 1A of the frame 1.
In the course of being brought up, it is guided by the rigid struts 9 and its position is maintained on the support surface 1A.

Thus, in the present embodiment, the sheet member 2
Although the position accuracy is kept high by both the flexible support 4 and the rigid support 9, the flexible support 4 is not used for any reason.
There is an advantage that the positional accuracy can be maintained by the rigid support columns 9 even if the outer surface accuracy of the device is reduced.

<Third Embodiment> In the first and second embodiments described above, the protruding columns are made elastically deformable. However, in the third embodiment shown in FIG. 3, the sheet member is moved in one specific direction. It is elastically deformable.

In FIG. 3, the protruding column 3 has a form in which the two flexible columns 4 of FIG. 1 are integrated. In other words, the pillar has a shape obtained by eliminating the gap 6 and the deep annular groove 5 from the one shown in FIG. 1, and as a result, the protruding pillar has rigidity. A locking claw 7 is provided on the projection 3.

On the other hand, two notches 10 are formed in the sheet member 2 at opposing positions in a diameter line direction Y perpendicular to the direction X in which the locking claws 7 of the protruding pillars 3 are located. Therefore, the sheet member 2 can elastically expand and contract in the direction X in the region of the edge of the locking hole 8. This is effective when the sheet member is relatively thin or soft.

Thus, in the present embodiment, the sheet member 2
At the time of attachment to the predetermined position, the engaging hole 8 is greatly expanded in the X direction and is locked to the protruding pillar 3, and after the elastic deformation is released, the locking claw 7 prevents the detachment. Also in this case, the circular locking hole 8
However, positional accuracy is ensured by the outer peripheral surface of the projecting pillar 3.

<Fourth Embodiment> Next, FIG. 4 shows an embodiment relating to a case where a plurality of sets of protrusions and engagement holes are provided. FIG. 4A is a plan view showing a state where the sheet member 2 holding a large number of compression contacts 12 is mounted on the frame 1.

In FIG. 4 (A), a thick strong support 11 is provided at one of the four corners of the frame.
As shown in FIG. 4 (B), the column 11 has no engagement claws and is rigid, and has a tapered surface 11A formed on the upper surface so as to facilitate attachment of the sheet member.

In each of the other three corners of the frame, a protruding column 3 shown in FIG. 1 is provided. In this case, the bending directions X of the flexible columns 4 of the respective projecting columns 3 are all different as shown in the drawing. Thereby, the direction in which the sheet member is most accurately positioned is not determined, and uniform accuracy is obtained.

In this embodiment, it goes without saying that the combination of the protruding column and the engaging hole is not limited to that shown in FIG. 1 but may be that shown in FIGS. 2 and 3.

<Fifth Embodiment> FIG. 5 shows an example in which the sheet member 2 can float as a fifth embodiment. In the present embodiment, the locking claw 7 is provided at a position where a sufficient gap is formed between the locking claw 7 and the sheet member 2 so that the sheet member 2 floats. Thus, the contact held by the floatable sheet member can sufficiently follow the displacement of the contact with the mating connector.

In the present invention, the frame is not limited to an enclosed frame. That is, it is sufficient that the frame can support the edge of the sheet member, and the frame may be supported on three sides, two sides, or one side. In this case, the frame does not need to be continuously formed in a linear shape, and may be scattered in an island shape at intervals.

[0039]

As described above, according to the present invention, a projection is provided on a frame to be engaged with an engagement hole of a sheet member of a connector, and at least one of the projection and an edge of the engagement hole is provided in one specific direction. Since it is elastically deformable, the protruding pillar and the engaging hole can be engaged so as to be in close contact with each other, so that the positional accuracy is improved, and
Since the mechanical strength is high, it can be held firmly, and since it does not take up much space, the size of the sheet member and, consequently, the entire apparatus can be reduced.
