Description

The present invention relates to an electric connector that electrically connects a cable and a circuit board to form an electric circuit.

Electronic components are equipped with a plurality of electronic elements, and in order to electrically connect the electronic elements arranged apart from each other, a flexible flat cable (FFC) or a flexible printed circuit (FFC) or a flexible printed circuit (FFC) is used. Circuit: FPC) is widely used. The flexible flat cable and the flexible printed circuit (hereinafter, commonly referred to as "cable") have a structure in which a plurality of terminals are arranged side by side in the width direction at their ends. Such a cable is removably connected to a connector mounted on the circuit board and electrically connected to the circuit board via the connector.

FIG. 13 is an example of the electric connector 10 according to the prior art, is a conceptual diagram for explaining the signal reflection phenomenon in the terminal 12, and FIG. 14 is a graph showing the impedance in the electric connector 10 shown in FIG. ..

As shown in FIG. 13, the electric connector 10 is mounted on the circuit board 2 and connected to the inserted cable 1 to electrically connect the cable 1 and the circuit board 2. Such an electric connector 10 is rotatably installed in the housing 11, the terminal 12 arranged in the longitudinal direction of the housing 11, and the cable 1 is fixed to the terminal 12 in a state of being connected to the housing 11. It includes an actuator 13 configured to release the fixation and a fitting nail 14 for fixing the housing 11 onto the circuit board 2.

The terminal 12 is provided with a soldering portion 12a mounted on the circuit board 2 at the rear end, and in front of the soldering portion 12a is a lower arm 12b in contact with the terminal portion of the cable 1 and one of the rotating shafts 13a of the actuator 13. It has a branched structure branched into an upper arm 12c surrounding the portion. For the support of the actuator 13 and the rotation guide, the upper arm of some terminals is configured to surround a part of the rotation shaft 13a, and the upper arm of the other terminal covers the other part of the rotation shaft 13a. It is configured to surround.

However, in the terminal 12, there is a problem that a signal reflection phenomenon (or a signal vortex phenomenon) occurs due to the branch structure. Specifically, when a signal is transmitted from the circuit board 2 to the cable 1 via the terminal 12, a part of the signal flowing into the terminal 12 via the soldering portion 12a is immediately cabled via the lower arm 12b. Instead of being transmitted to 1, the signal is reflected while passing through the upper arm 12c.

As shown in FIG. 14, the impedance of the electric connector 10 drops sharply due to the signal reflection phenomenon described above. Since the signal reflection phenomenon due to such a branched structure hinders high-speed transmission of signals, there is a problem that the electric connector 10 provided with the terminal 12 having a branched structure is not suitable for high-speed transmission.

If the design of the terminal 12 is changed so as not to include the upper arm 12c in order to solve the above problem, there arises a problem that the actuator 13 is not smoothly supported and rotated. Therefore, research is being conducted on an electric connector 10 capable of smoothly supporting and rotating the actuator 13 while reducing the signal reflection phenomenon.

On the other hand, in order to stabilize the connection between the cable 1 and the terminal 12, the actuator 13 must pressurize the cable 1 as uniformly as possible. In the prior art, the upper arm 12c of some terminals 12 is configured to support the upper side of the actuator 13, and the actuator 13 is partially pressurized downward. Therefore, when the terminal 12 without the upper arm 12c is applied in order to prevent the signal reflection phenomenon described above, the actuator 13 cannot uniformly pressurize the cable 1, and the connection between the cable 1 and the terminal 12 is stable. And will not be done.

Further, although the assembler usually looks down at the electric connector 10 and inserts the cable 1, the actuator 13 may hide the insertion position of the cable 1 in the open state. Further, on the upper side of the electric connector 10, it is difficult to easily grasp with the naked eye whether or not the actuator 13 has been switched to the completely closed state. Therefore, in order to confirm them, there is an inconvenience that the assembler must look at the electric connector 10 from an oblique direction or a lateral direction.

On the other hand, the cable 1 may be incompletely inserted into the electric connector 10 due to an assembly error of the assembler or the like. In this case, there arises a problem that the terminal portion of the cable 1 and the connection portion of the terminal 12 do not come into contact with each other at a fixed position. Therefore, research is being conducted on a technique for correcting such incomplete insertion of the cable 1 by the operation of the actuator 13.

The background technique of the present invention is disclosed in Patent Document 1 (published on September 5, 2013).

When the metal shell 130 is mounted on the housing 110 to form the accommodating portion 113 in this way, a slim structure is realized in which the upper portion of the actuator 140 is uniformly pressed while the actuator 140 is completely inserted into the accommodating portion 113. be able to. If the housing 110 is extended to form a metal shell portion, the metal shell portion must be made very thick in order to realize a structure in which the upper part of the actuator 140 is pressed uniformly to the same extent as the metal shell 130. Must be. Therefore, according to this structure using the metal shell 130, it is possible to realize a slim electric connector 100 capable of ensuring contact reliability under height restrictions.

The actuator 140 is rotatably and slidably installed in the housing 110 and is formed so as to be inserted into the accommodating portion 113 when sliding. The actuator 140 is made of a non-conductive synthetic resin material.

As shown in FIG. 4, the actuator 140 is located between the first position (I) where the insertion portion 143 is located on the metal shell 130 and the second position (II) where the insertion portion 143 is located in front of the accommodating portion 113. Formed rotatably. Further, the actuator 140 is formed so as to be slidable between the second position (II) and the third position (III) in which the insertion portion 143 is inserted into the accommodating portion 113.

The actuator 140 is in the open state at the first position (I) and in the closed state at the third position (III).

The actuator 140 rotates and then slides when transitioning from the open state to the closed state, and slides and then rotates when transitioning from the closed state to the open state.

In the open state, the cable 1 is inserted into the accommodating portion 113 and is located on the cable mounting surface 112, and in the closed state, a part of the actuator 140 (insertion portion 143) is inserted into the accommodating portion 113 and the cable 1 is inserted. Is tightly fixed on the cable mounting surface 112. At this time, the connection portion 122a of the terminal 120 is connected to the terminal portion 1a of the cable 1.

For the rotation and sliding of the actuator 140, slot portions 116 are extended in the front-rear direction of the housing 110 on both sides of the housing 110.

The insertion portion 143 is formed so as to project from the base portion 141 between the two floating hinge portions 142 arranged apart from each other and to be inserted into the accommodating portion 113 or taken out from the accommodating portion 113 at the time of sliding. To.

5 is a perspective view showing the rotation and sliding process of the actuator 140 shown in FIG. 4, FIG. 6 is a plan view showing the rotation and sliding process of the actuator 140 shown in FIG. 4, and FIG. 7 is a plan view showing the rotation and sliding process of the actuator 140. FIG. 6 is a cross-sectional view taken along the line AA'of FIG. 6 showing the rotation and sliding process of the actuator 140 shown in FIG. 6, and FIG. 8 is a side view showing the rotation and sliding process of the actuator 140 shown in FIG. ..

As shown in (a) of each of the above figures, the accommodating portion 113 is in a state of being opened forward in a state where the actuator 140 is located at the first position (I). That is, the cable 1 can be inserted into the accommodating portion 113.

As shown in FIG. 6A, in a state where the actuator 140 is located at the first position (I), the actuator 140 has a metal shell 130 in the thickness direction of the housing 110, specifically, the front end of the main body 131. It is arranged so as not to cover the part. That is, the actuator 140 at the first position (I) is arranged in a state of being warped rearward so that the front side of the metal shell 130 can be seen from above.

At this time, the actuator 140, specifically the base portion 141, comes into contact with the metal shell 130. That is, the metal shell 130 is formed so as to support the actuator 140, specifically, the base portion 141.

Further, as shown in FIGS. 5A and 8A, the floating hinge portion 142 of the actuator 140 is arranged so as to be inclined rearward. That is, the first and second connecting portions 142b and 142c, which will be described later, extend backward from the hinge shaft portion 142a and are connected to the base portion 141.

According to the above arrangement, the actuator 140 does not block the field of view of the assembler who looks down at the electric connector 100 and connects the cable 1 to the electric connector 100. Therefore, the assembler can easily confirm with the naked eye whether or not the cable 1 has been inserted into the fixed position of the accommodating portion 113 from above the electric connector 100.

When the cable 1 is inserted at a fixed position in the accommodating portion 113, the cable 1 is located on the cable mounting surface 112, and the terminal portion 1a of the cable 1 is arranged so as to overlap the connecting portion 122a of the terminal 120. However, since the terminal portion 1a is merely placed on the connection portion 122a, energization is not stably performed.

On the other hand, the metal shell 130, specifically the main body 131, is arranged so as to completely cover the connecting portion 122a in the thickness direction of the housing 110. As shown in FIG. 7C, the main body 131 of the metal shell 130, the insertion portion 143 of the actuator 140, the terminal portion 1a of the cable 1, and the connection portion 122a of the terminal 120 are in the thickness direction of the electric connector 100. It is arranged so as to overlap with. This is a structure for the main body portion 131 to cover and support the upper side of the insertion portion 143 so that the terminal portion 1a is firmly connected to the connection portion 122a.

The actuator 140 located at the first position (I) moves to the second position (II) by rotation.

As shown in (b) of each of the above figures, the actuator 140 is arranged in front of the accommodating portion 113 in a state where the actuator 140 is located at the second position (II). At this time, the insertion portion 143 of the actuator 140 is arranged so as to cover the cable 1. However, the insertion portion 143 does not overlap the terminal portion 1a of the cable 1 and the connection portion 122a of the terminal 120 in the thickness direction of the electric connector 100.

At this time, the insertion portion 143 and the metal shell 130 are arranged so as to be separated from each other by a predetermined distance as shown in the drawing, and a part of the cable 1 is exposed from the gap created by the separation.

Further, as shown in (b) of FIG. 5 and (b) of FIG. 8, the floating hinge portion 142 of the actuator 140 is arranged side by side in the slot portion 116. That is, the first and second connecting portions 142b and 142c, which will be described later, extend forward from the hinge shaft portion 142a and are connected to the base portion 141.

The actuator 140 located at the second position (II) moves to the third position (III) by sliding.

As shown in (c) of each of the above figures, the insertion portion 143 of the actuator 140 is inserted into the accommodating portion 113 in a state where the actuator 140 is located at the third position (III). At this time, the metal shell 130 covers and supports the upper side of the insertion portion 143 so that the insertion portion 143 pressurizes the cable 1 toward the connection portion 122a.

When the insertion portion 143 is completely inserted into the accommodating portion 113, the insertion portion 143 brings the cable 1 into close contact with the cable mounting surface 112, and in the process, the terminal portion 1a of the cable 1 is exposed from the cable mounting surface 112. Contact the connection portion 122a of the terminal 120. At this time, since the metal shell 130 covers and supports the upper side of the insertion portion 143, the connection between the terminal portion 1a and the connection portion 122a is stably maintained.

When the structure for fixing the metal shell 130 to the housing 110 includes only the fixing portions 132 provided on both sides of the metal shell 130 described above (corresponding to the first fixing portion 132 of the present embodiment), the intermediate portion of the metal shell 130. Since the force for covering and supporting the upper side of the insertion portion 143 is weak, a poor connection between the terminal portion 1a and the connection portion 122a may occur. Such a phenomenon is more likely to occur as the electric connector 100 becomes longer.

Here, if the fixed portion 133 which is arranged at a predetermined interval in the longitudinal direction of the metal shell 130 described above is further included (corresponding to the second fixed portion 133 of the present embodiment), the intermediate portion of the metal shell 130 is also inserted. The upper side of the portion 143 is firmly supported, and a poor connection between the terminal portion 1a and the connection portion 122a can be prevented.

Further, as shown in (c) of FIG. 5 and (c) of FIG. 8, the floating hinge portion 142 of the actuator 140 moves rearward along the slot portion 116. That is, the hinge shaft portion 142a, which will be described later, moves toward the rear end portion in the slot portion 116.

In the operation of the actuator 140 described above, the insertion portion 143 is an important configuration for stable connection between the terminal portion 1a of the cable 1 and the connection portion 122a of the terminal 120. Explaining only the operation of the insertion portion 143 separately, the insertion portion 143 has a first position (I) located on the metal shell 130 and a second position (II) located in front of the accommodating portion 113 due to the rotation of the actuator 140. It moves between the second position (II) and the third position (III) inserted into the accommodating portion 113 by sliding the actuator 140.

On the other hand, when the insertion portion 143 is completely inserted into the accommodating portion 113, the actuator 140 may be locked to the housing 110. That is, the actuator 140 may not come out in the opposite direction.

Hereinafter, the structure that realizes the rotation and sliding of the actuator 140 and the lock structure of the actuator 140 will be described in more detail.

9 is an enlarged view of a portion B shown in FIG. 5B, and FIG. 10 is a cross-sectional view taken along the line CC'of FIG. 9 showing a sliding process of the actuator 140 shown in FIG.

As shown in FIGS. 9 and 10, slot portions 116 are provided on both sides of the accommodating portion 113 so that the floating hinge portions 142 can be inserted and rotated and slid. The slot portion 116 extends long in the front-rear direction of the housing 110.

The slot portion 116 includes a first extension portion 116a, a second extension portion 116b, and a locking projection 116c.

The first extension portion 116a and the second extension portion 116b extend from the rear portion of the housing 110 toward the front so as to face each other, and the idle hinge portion 142 is inserted to form a free space for rotation and sliding.

In the present embodiment, the first extension portion 116a and the second extension portion 116b extend forward from the upper surface and the lower surface of the rear portion of the housing 110, respectively. That is, the first extension portion 116a and the second extension portion 116b are arranged in parallel in the vertical direction of the housing 110. The first extension portion 116a and the second extension portion 116b form the upper side and the lower side of the slot portion 116, respectively.

However, the present invention is not limited to this. As a design modification example, the first extension portion 116a and the second extension portion 116b may be arranged parallel to the lateral direction of the housing 110. In this case, the first extension portion 116a and the second extension portion 116b form the left side and the right side of the slot portion 116, respectively.

The locking projections 116c project from at least one front portion of the first and second extension portions 116a and 116b toward the idle space between the first extension portion 116a and the second extension portion 116b, and the idle space To limit. Here, limiting the floating space means that the movement of the hinge shaft portion 142a of the floating hinge portion 142, which will be described later, is restricted by the locking projection 116c.

In the present embodiment, the case where the locking projection 116c is projected from each of the first and second extension portions 116a and 116b is shown.

However, the present invention is not limited to this. As a design modification, the locking projection 116c may be projected only from either the first and second extension portions 116a and 116b.

The floating hinge portion 142 includes a hinge shaft portion 142a, a first connecting portion 142b, and a second connecting portion 142c.

The hinge shaft portion 142a is arranged in the floating space, is formed so as to rotate in the floating space and slide along the floating space.

The first connecting portion 142b and the second connecting portion 142c are arranged in parallel on both sides of the hinge shaft portion 142a and are connected to the base portion 141. In the present embodiment, the first connecting portion 142b and the second connecting portion 142c are arranged parallel to each other in the lateral direction of the housing 110.

On the other hand, the housing 110 is provided with an opening 117 and a notch 118 communicating with the slot 116 so that the actuator 140 can rotate between the first position (I) and the second position (II). In the present embodiment, an opening 117 is provided between the accommodating portion 113 and the slot portion 116 to form a space in which the first connecting portion 142b rotates, and a notch portion 118 is provided on the outside of the slot portion 116. The connecting portion 142c forms a rotating space.

An inclined surface 118a may be formed in the notch 118 so as to support the second connecting portion 142c which is inclined rearward while the actuator 140 is located at the first position (I). With the actuator 140 located at the first position (I), the insertion portion 143 is supported by the metal shell 130, and the floating hinge portion 142 is supported by the inclined surface 118a.

On the other hand, the opening 117 is formed so as to open forward due to the sliding of the first connecting portion 142b and upward due to the rotation of the first connecting portion 142b. Therefore, the first connecting portion 142b is exposed upward from the opening 117.

As shown in FIG. 6B, the first connecting portion 142b is arranged apart from the rear end of the opening 117 in a state where the actuator 140 is located at the second position (II). Therefore, when the opening 117 is viewed from above, the space inside the opening 117 can be seen because the first connecting portion 142b is not completely inserted into the opening 117.

As shown in FIG. 6 (c), the first connecting portion 142b is completely inserted to the rear end of the opening 117 in a state where the actuator 140 is located at the third position (III). Therefore, when the opening 117 is viewed from above, the space inside the opening 117 cannot be seen because the first connecting portion 142b is completely inserted into the opening 117.

Utilizing such a difference, the assembler can confirm the sliding state of the floating hinge portion 142 from above the electric connector 100 based on the position of the first connecting portion 142b in the opening 117.

On the other hand, as a design modification example, an opening 117 may be provided on the outside of the slot 116 instead of the notch 118. In this case, the assembler can also confirm the sliding state of the floating hinge portion 142 based on the position of the second connecting portion 142c in the opening 117.

Further, as a design modification example, when the first extension portion 116a and the second extension portion 116b are arranged in parallel in the lateral direction of the housing 110, the first connecting portion 142b and the second connecting portion 142c are respectively hinge shaft portions. It may be arranged parallel to the upper part and the lower part of 142a.

On the other hand, at least one of the first and second connecting portions 142b and 142c may be provided with a lock projection 142d. The lock protrusion 142d is formed so as to project toward the space between the first connecting portion 142b and the second connecting portion 142c and to be locked to the locking protrusion 116c when the floating hinge portion 142 slides. ..

In the present embodiment, the case where the lock protrusion 142d is projected from the first connecting portion 142b is shown.

However, the present invention is not limited to this. As a design modification example, the lock protrusion 142d may be projected from the second connecting portion 142c, or may be projected from each of the first connecting portion 142b and the second connecting portion 142c.

With the actuator 140 located at the second position (II), the locking projection 142d is located in front of the locking projection 116c.

In this state, when the actuator 140 receives an external force and slides toward the third position (III), the lock projection 142d gets over the locking projection 116c by the external force. At this time, the first and second extension portions 116a and 116b or the first and second connecting portions 142b and 142c are elastically deformed.

With the actuator 140 located at the third position (III), the locking projection 142d is located behind the locking projection 116c, i.e. within the slot portion 116.

Hereinafter, a structure for stably connecting the cable 1 and the terminal 120 even if the cable 1 is incompletely inserted into the accommodating portion 113 will be described.

11 is a conceptual diagram showing the sliding process of the actuator 140 at the bottom of the D portion shown in FIG. 6B, and FIG. 12 is a conceptual diagram showing the sliding process of the actuator 140 shown in FIG. FIG. 5 is a cross-sectional view taken along the line EE.

As shown in FIGS. 11 and 12, cable insertion guides 143a are provided on both sides of the insertion portion 143. The cable insertion guide 143a protrudes from the bottom of the insertion portion 143, and the actuator 140 is arranged so as to cover the cable 1 (a state in which the actuator 140 is located between the second position (II) and the third position (III)). , Is inserted into the recesses 1b formed on both sides of the cable 1.

Here, the recess 1b of the cable 1 is extended with a predetermined length along the extension direction of the cable 1, and the cable insertion guide 143a is formed shorter than the length of the recess 1b of the cable 1.

When the cable 1 is completely inserted into the accommodating portion 113, when the actuator 140 slides, the cable insertion guide 143a moves relative to the recess 1b of the cable 1. At this time, the position of the cable 1 does not move, and only the cable insertion guide 143a moves in the recess 1b of the cable 1.

If the cable 1 is not completely inserted into the accommodating portion 113 and the actuator 140 slides from the second position (II) to the third position (III), the cable insertion guide 143a fits into the recess 1b of the cable 1. It is locked and pushes the cable 1 toward the accommodating portion 113. That is, when the actuator 140 slides, the cable 1 is pulled into the accommodating portion 113 by the cable insertion guide 143a. Therefore, the cable 1 moves to a fixed position of the accommodating portion 113, and the connection between the cable 1 and the terminal 120 is stably performed.

With the actuator 140 located at the third position (III), the cable 1 is completely inserted into the accommodating portion 113, and the cable insertion guide 143a contacts the end of the recess 1b. At this time, the cable insertion guide 143a does not push the cable 1 any more.

A cable insertion recess 119 into which the cable insertion guide 143a is inserted is formed on the cable mounting surface 112. The cable insertion recess 119 is arranged outside the terminal mounting portion 111.

On the other hand, as described above, in the state where the actuator 140 is located at the third position (III), the lock projection 142d is located in the slot portion 116, and the locking projection 116c is located in front of the lock projection 142d. Therefore, if an external force equal to or greater than a predetermined value is not applied, the lock projection 142d is locked to the locking projection 116c, and the actuator 140 does not slide forward.

In this way, with the actuator 140 firmly fixed to the third position (III), the cable 1 may be unexpectedly pulled due to an assembler's mistake or the like. In this case, the recess 1b of the cable 1 is locked to the cable insertion guide 143a, so that the cable 1 cannot be pulled out. Therefore, according to the above structure, the connection stability between the cable 1 and the electric connector 100 is guaranteed.
