Abstract

PROBLEM TO BE SOLVED: To facilitate connection work of a sheet shaped conducting path (FPC) to be inserted along a substrate. SOLUTION: An insertion chamber 12 is formed at an upward part of a terminal housing chamber 12 in a connector housing 10, and an operation member 20 that can be slid along a ceiling face is arranged in that insertion chamber 13. In each terminal housing chamber 12, a terminal piece 30 is assembled, and at that terminal end 30, there are formed an elastic contact piece part 31 for pressing an FPC inserted into the insertion chamber 13 and a press reception part 32 pressed by the operation member 20 and slackening the elastic contact piece part 31 in an opposite direction to a pressing direction. Thereby, since operation of the operation member 20 or insertion and removal of the FPC can be performed at a high position relatively distant from a substrate face, connection work is facilitated, and since the elastic contact piece part 31 can be slackened by pressing a tip end part more, that operation force may be small.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet-like conductive path connector for connecting a sheet-like conductive path such as an FPC.

[0002]

2. Description of the Related Art A connector of this type is disclosed in Japanese Unexamined Patent Publication No.
The one disclosed in Japanese Patent Application No. 182722 is known.
This will be described below with reference to FIG. The connector housing 1 is mounted vertically on the board S, and an insertion chamber 3 is formed in the inside thereof so that the flat cable 2 can be inserted from above. A terminal piece 4 is attached to the connector housing 1.
Of the connector housing 1 projects from the bottom of the connector housing 1
To be soldered. The upper end of the terminal piece 4 extends upward on the left side wall of the insertion chamber 3 and is then bent inward so as to form an elastic contact piece 5 to be inserted into the insertion chamber 3. The flat cable 2 is pressed against the right side wall so as to make elastic contact therewith.

Further, an operating member 6 which can be slid up and down is provided at the upper end of the left side wall so as to press a base portion of the elastic contact piece portion 5 to elastically deform the same in a direction opposite to the pressing direction. I have to. In other words, if the elastic contact piece portion 5 is constantly urged in the direction of pressing the flat cable 2, the flat cable 2 cannot be smoothly inserted and removed, so that when the flat cable 2 is inserted and removed, it is elastically deformed in the direction opposite to the pressing direction. To insert and remove the flat cable 2

[0004]

However, in the above configuration, since the operating member presses the attaching portion of the elastic contact piece and elastically deforms the elastic contact piece in the direction opposite to the pressing direction, the operation member is not compared with the operation of the operating member. It needed great power. In addition, in the pressing operation of the base portion, the elastic contact piece portion is greatly deformed by a slight stroke, so that the stroke amount of the operation member cannot be set unnecessarily large, and it is difficult to control the elastic contact piece portion. for that reason,
With the connector having the above configuration, the work of inserting and removing the flat cable is not always easy.

[0005] Also, consider the case where the above-described connector configuration is applied to a connector that is mounted horizontally on a board and a flat cable is inserted along the board. In this case,
If the operation member is disposed on the side in contact with the substrate, the operation member must be operated at a low position, and thus there is a problem that the operation is difficult. Also, if the operation member is arranged on the side opposite to the side in contact with the substrate, the operation member can be operated at a relatively high position away from the substrate, so that the operation does not become difficult, but in this case, On the contrary, the insertion position of the flat cable becomes a low position in contact with the substrate, and there is a problem that it becomes difficult to insert the flat cable. In short, in the above configuration, the side on which the flat cable is pressed and the side on which the operating member is arranged are in an opposite relationship to each other. Therefore, when the connector is mounted on the board in a horizontal position, the operating member is located on either the upper or lower side. Even if it does, the problem that the work of inserting and removing the flat cable is difficult is caused.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a sheet-like conductive path connector according to an embodiment of the present invention; FIG. The connector for a sheet-like conductive path according to the present embodiment is a connector for connecting an FPC. As shown in FIG. 1, the connector has a flat rectangular parallelepiped connector housing 10 and a connector housing 1 having a flat rectangular parallelepiped shape.
The connector comprises an operation member 20 slidably mounted on the FPC 40 and a plurality of terminal pieces 30 assembled in the connector housing 10 and elastically contacting the FPC 40.

A plurality of terminal accommodating chambers 12 are provided in the connector housing 10 in a lateral direction (in FIG. 1, a direction perpendicular to the plane of the drawing).
In this case, a terminal piece 30 described later is accommodated through a terminal mounting port 12A formed on the rear surface side. Further, the upper end of the partition separating each terminal accommodating chamber 12 is cut out, whereby the upper part of each terminal accommodating chamber 12 is connected to form an insertion chamber 13 into which the FPC 40 is inserted. Further, an opening formed in the front surface of the connector housing 10, that is, a lower edge portion of the insertion port 11 for inserting the FPC 40 is inclined inward and upward to guide the guide surface 14 for guiding the FPC 40 to the insertion chamber 13. Has formed.

As shown in FIG. 5, the operating member 20 has an arm piece 21 extending rearward on both left and right sides (in FIG. 5, near side and far side). This arm piece 21 is provided with guide grooves 15 formed on both left and right sides of the connector housing 10.
The operation member 20 is slidable in the front-rear direction. At the tip of the arm piece 21, FIG.
As shown in FIG. 1, an engagement protrusion 21A is formed on the inner side surface, and an engagement hole 1 formed in a substantially central portion of the guide groove 15 is formed.
It fits into 5A. Accordingly, the forward (rightward in FIG. 3) movement of the operation member 20 is restricted by the engagement of the engagement protrusion 21A with the front edge of the engagement hole 15A, and the rearward movement (left in FIG. 3). The movement of the connector housing 10 is regulated by the contact of the connecting portion 22 connecting the two arm pieces 21 with the front edge of the upper surface of the connector housing 10.

Further, a rear edge (left edge in FIG. 3) of the connecting portion 22 of the operating member 20 extends into the insertion chamber 13 to form an operating portion 23. The rear edge of the operation section 23 is formed with a notch corresponding to the terminal piece 30 assembled in each terminal accommodating chamber 12, and when the operation member 20 is slid backward, the protrusion 23A is formed in each terminal piece. Each of the thirty press receiving portions 32 is pressed downward. The lower surface of the connecting portion 22 is notched obliquely inward, and the guide surface 22 guides the FPC 40 together with the guide surface 14 to the lower space of the operation unit 23 in the insertion chamber 13.
A.

Each terminal piece 30 is formed by punching a conductive metal plate into a substantially U-shape, and is assembled in the terminal accommodating chamber 12 with the curved side facing forward. In this assembled state, the upper part (hereinafter referred to as an elastic contact piece) 31 of each terminal piece 30 is capable of bending and deforming vertically.
A contact portion 31A projecting upward is formed at the center thereof. Then, in the normal state, the contact portion 31A
Is urged upward to form a very small gap between itself and the operation member 20 (the state shown in FIG. 1).

The rear end of this elastic contact piece 31 (in FIG. 1,
The left end is curved upward and extends into the insertion chamber 13. Then, the convex portion 23A of the operation unit 23 is pressed here. This portion corresponds to the press receiving portion 32 according to the present invention. In the normal state, the operating member 20 is urged forward by the pressing receiving portion 32. When the operating member 20 is slid rearward (to the left in FIG. 1), the pressing receiving portion 32 is pressed downward to contact the operating member 20. The portion 31A is pressed down to form a gap between the operation portion 23 and the FPC 40 in a thickness greater than the thickness of the FPC 40 (a state shown in FIG. 2).

Further, a lower portion of the terminal piece 30 (hereinafter, referred to as a terminal piece 30)
As shown in FIG. 4, two engagement protrusions 33 </ b> A are formed on each of the lower side portions 33 on both side surfaces extending in the length direction. The engagement protrusion 33A is formed by being punched out from the other side. On the other hand, on the inner wall of the terminal accommodating chamber 12, an engagement recess 12B is formed corresponding to each engagement protrusion 33A. Then, by the engagement of the two, the terminal piece 30 is held in a state of being assembled in the terminal accommodating chamber 12. The rear end of the lower piece 33 protrudes from the terminal assembling opening 12A to form a soldering portion 33B. By soldering this to the substrate S, the connector can be mounted on the substrate S. Done.

The FPC 40 will be described briefly. FIG.
As shown in FIG. 5, the FPC 40 has a three-layer structure, and resin films 41 and 42 are provided on both upper and lower sides.
A conductive pattern 43 is provided between the films 41 and 42 in a sandwich state. At the insertion end of the connector housing 10 into the insertion chamber 13, the lower film 42 is peeled off, and the conductive pattern 43 is exposed.

Next, the operation of connecting the FPC 40 to the connector will be described. In the normal state, as described above, the operation member 20 is urged forward and is in the state shown in FIG.
Then, when the operation member 20 is slid backward (to the left in FIG. 1), the press receiving portion 32 of each terminal piece 30 is moved to the operation portion 2.
It is pressed downward by the third convex portion 23A. Thereby, the elastic contact piece 31 bends downward, and a gap larger than the thickness of the FPC 40 is formed between the contact section 31A and the operation section 23 (see FIG. 2). Then, the end of the FPC 40 is inserted into the insertion chamber 13 through the insertion port 11. At this time, FP
C40 is guided by the guide surfaces 14 and 22A into the lower space of the operation unit 23 in the insertion chamber 13.

The FPC 40 inserted into the insertion chamber 13
It is pushed further inward through the gap formed between the operation part 23 and the contact part 31A. And the operation member 2
When the sliding operation of “0” is stopped, the operating member 20 is pushed back slightly forward by the resilient force from each of the press receiving portions 32, and is pressed against the ceiling surface of the insertion chamber 13 together with the FPC 40 by the return of the contact portion 31A. Thereby, the movement of the operation member 20 stops. At the same time, the FPC is sandwiched between the operation part 23 and the contact part 31A, and the contact part 31A and the conductive pattern 43 make elastic contact.

To remove the FPC 40, use the FPC 4
0 slides the operation member 20 backward from a position sandwiched between the operation unit 23 and the contact unit 31A. Then, similarly to the above, the press receiving portion 32 is pressed downward, and the contact portion 31A is pressed down. As a result, the contact portion 31A separates from the FPC 40, so that the FPC 4
0 may be extracted from the insertion chamber 13.

As described above, in the present embodiment, the insertion chamber 13 for inserting the FPC 40 is formed at the upper part in the connector housing 10 and the operation member 2 is formed therein.
0 is arranged. The FPC 40 inserted into the insertion chamber 13 is sandwiched between the elastic contact piece 31 and the operation unit 23. Therefore, when mounted on the board S, the operation of the operation member 20 and the insertion and removal of the FPC 40 can be performed at a relatively high position away from the board surface, so that the connection work of the FPC 40 is facilitated. In addition, a pressure receiving portion 32 is connected to the distal end side of the elastic contact piece portion 31, and the elastic contact piece portion 31 is pressed by the operation member 20 so that the elastic contact piece portion 31 is bent in a direction opposite to the pressing direction against the FPC 40. Therefore, the operating force can be made smaller than before.

Since the insertion surface 11 for the FPC 40 is formed with the guide surfaces 14 and 22A,
C40 can be smoothly guided into the insertion chamber 13.
Further, each terminal piece 30 is provided with an engagement projection 33A and an engagement recess 12.
Since each terminal piece 30 is held by engagement with B, it can be held in a state where each terminal piece 30 is securely positioned.

The present invention is not limited to the above-described embodiment, but can be modified as follows, for example, and these embodiments also belong to the technical scope of the present invention. (1) Although the above embodiment shows an example in which the invention is applied to a connector for connecting the FPC 40, the invention may be applied to a connector for connecting a flat cable, a tape wire, or the like.

(2) In the above embodiment, the terminal piece 30 is formed by punching a metal plate into a substantially U shape.
It may be formed by bending an elongated metal plate into a substantially U-shape.

(3) In the above embodiment, the terminal piece 30 is held in an assembled state by engaging the engaging projection 33A with the engaging recess 12B formed on the inner wall of the terminal accommodating chamber 12. However, a configuration in which a recess is formed in the terminal piece and the protrusion on the housing side is engaged therewith, or a configuration in which a protrusion piece is formed on the terminal piece and engages with the notch on the housing side may be used. . In addition, the present invention can be implemented with various modifications without departing from the scope.
