Description

Electrical connector {ELECTRICAL CONNECTOR}

The present invention relates to an electric connector for constructing an electric circuit by electrically connecting a cable and a circuit board.

Electronic devices are equipped with a number of electronic devices, and in order to electrically connect electronic devices spaced apart from each other, flexible flat cables (FFC) and flexible printed circuits (FPC) are widely used. Is being used. The flexible flat cable and the flexible printed circuit (hereinafter, collectively referred to as'cable') have a structure in which a plurality of terminals are arranged side by side along the width direction at the end of the cable. Such a cable is detachably connected to a connector mounted on a circuit board, and is electrically connected to the circuit board through the connector.

1 is a conceptual diagram for explaining a signal reflection phenomenon in a terminal 12 as an example of an electrical connector 10 according to the prior art, and FIG. 2 is an impedance of the electrical connector 10 shown in FIG. It is a graph showing.

1, the electrical connector 10 is mounted on the circuit board 2 and is connected to the inserted cable 1 to electrically connect the cable 1 and the circuit board 2 to each other. These electrical connectors 10 are rotatably installed in the housing 11, the terminals 12 arranged along the longitudinal direction of the housing 11, and the housing 11 to connect the cable 1 to the terminal 12. The actuator 13 is formed to fix or release the fixing in a state, and a fitting nail 14 for fixing the housing 11 on the circuit board 2.

The terminal 12 includes a soldering part 12a mounted on the circuit board 2 at the rear end, and a lower arm 12b and an actuator 13 in contact with the terminal of the cable 1 in front of the soldering part 12a. ) Has a branched structure with an upper arm 12c surrounding a part of the rotation shaft 13a. For reference, in order to support and guide the rotation of the actuator 13, 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 is configured to surround another part of the rotation shaft 13a. do.

However, in the terminal 12, there is a problem in that a signal reflection phenomenon (or a signal vortex phenomenon) occurs due to the above-described branched structure. Specifically, when a signal is transmitted from the circuit board 2 to the cable 1 through the terminal 12, a part of the signal flowing into the terminal 12 through the soldering part 12a is the lower arm 12b. ), it cannot be directly transmitted to the cable 1, and signal reflection occurs while passing through the upper arm 12c.

Referring to FIG. 2, it can be seen that the impedance of the electrical connector 10 is rapidly reduced due to the reflection of the signal described above. The reflection of the signal due to the branched structure interferes with high-speed transmission of the signal, so that the electric connector 10 having the branched terminal 12 is not suitable for high-speed transmission.

In order to solve the above-described problem, when the design is changed so that the terminal 12 does not have the upper arm 12c, there arises a problem that the support and rotation of the actuator 13 cannot be performed smoothly. Accordingly, research is being conducted on the electric connector 10 that can reduce the signal reflection phenomenon and smoothly support and rotate the actuator 13.

On the other hand, for a stable connection between the cable 1 and the terminal 12, the actuator 13 must press the cable 1 as uniformly as possible. Conventionally, the upper arm 12c of some of the terminals 12 is formed to support the upper side of the actuator 13, so that the actuator 13 is pressed downwardly in some places. However, if the terminal 12 without the upper arm 12c is applied to prevent the above-described signal reflection phenomenon, the actuator 13 cannot uniformly press the cable 1, and thus the cable 1 and the terminal The connection between (12) may not be established stably.

In addition, the assembler typically performs the cable 1 insertion work while looking down the electrical connector 10, but there is a case where the insertion position of the cable 1 is covered while the actuator 13 is open. In addition, it was difficult to easily grasp with the naked eye whether the actuator 13 has been switched to a completely closed state from the upper side of the electrical connector 10. Therefore, in order to check these, there is an inconvenience that the assembler must look at the electrical connector 10 at an angle or from the side.

On the other hand, it may occur that the cable 1 is less inserted into the electrical connector 10 due to an assembly mistake by the assembler. In this case, a problem arises that the terminal portion of the cable 1 and the connection portion of the terminal 12 do not contact at the correct position. Accordingly, research is being conducted on a technique in which the incomplete insertion of the cable 1 can be corrected by the operation of the actuator 13.

A structure for fixing the metal shell 130 to the housing 110, that is, when the above-described fixing portions 132 are provided only on both sides of the metal shell 130 (corresponding to the first fixing portions 132 in this embodiment) , In the middle portion of the metal shell 130, the force to cover and support the upper side of the insertion portion 143 is weak, so that a connection failure between the terminal portion 1a and the connection portion 122a may occur. This phenomenon may occur more easily as the electrical connector 100 is extended and formed.

At this time, if the above-described fixing portion 133 is additionally formed to be spaced apart at a predetermined interval along the length direction of the metal shell 130 (corresponding to the second fixing portion 133 in this embodiment), the metal shell 130 Even in the middle portion of, the upper side of the insertion portion 143 is strongly supported so that a connection failure between the terminal portion 1a and the connection portion 122a can be prevented.

In addition, referring to FIGS. 7C and 10C, the flow hinge portion 142 of the actuator 140 is moved rearward along the slot 116. That is, the hinge shaft portion 142a to be described later is moved toward the rear end portion within the slot portion 116.

In the operation of the actuator 140 described above, the insertion portion 143 is an important component for a stable connection between the terminal portion 1a of the cable 1 and the connection portion 122a of the terminal 120. Looking at only the operation of the insertion part 143 separately, the insertion part 143 is located at the first position (I) on the metal shell 130 by the rotation of the actuator 140 and the front of the receiving part 113 It is moved between the second position (II) located in the, and is moved between the second position (II) and the third position (III) inserted into the receiving portion 113 by the slide movement of the actuator 140.

Meanwhile, when the insertion part 143 is completely inserted into the receiving part 113, the actuator 140 may be formed to be locked to the housing 110. That is, the actuator 140 may be formed so that it does not come out in the opposite direction.

Hereinafter, a structure for implementing rotation and slide movement of the actuator 140 and a locking structure of the actuator 140 will be described in more detail.

FIG. 11 is a perspective view showing a portion B shown in FIG. 7(b), and FIG. 12 is a conceptual diagram showing a slide movement process of the actuator 140 by cutting along the line C-C' shown in FIG. 11.

11 and 12, a flow hinge portion 142 is inserted at both sides of the receiving portion 113, and slots 116 formed to rotate and slide are provided. The slot 116 is formed to extend long along the front and rear direction of the housing 110.

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

The first extension part 116a and the second extension part 116b extend to face each other from the rear side of the housing 110 toward the front, and the flow hinge part 142 is inserted to create a flow space capable of rotating and sliding. To form.

In this embodiment, the first extension part 116a and the second extension part 116b extend forward from the upper and lower surfaces of the rear side of the housing 110. That is, the first extension part 116a and the second extension part 116b are disposed in parallel in the vertical direction of the housing 110. The first extension part 116a and the second extension part 116b form upper and lower sides of the slot part 116, respectively.

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

The locking protrusion 116c is formed to protrude toward the flow space between the first and second extensions 116a and 116b from the front side of at least one of the first and second extensions 116a and 116b, Define the flow space. Here, the meaning of limiting the flow space means that the movement of the hinge shaft portion 142a of the flow hinge portion 142 to be described later is restricted by the locking protrusion 116c.

In this embodiment, it is shown that the locking protrusion 116c protrudes from each of the first and second connection portions 142b and 142c.

However, the present invention is not limited thereto. As a design modification example, the locking protrusion 116c may be formed to protrude only from one of the first and second connection portions 142b and 142c.

The flow hinge part 142 includes a hinge shaft part 142a, a first connection part 142b, and a second connection part 142c.

The hinge shaft portion 142a is disposed in the flow space, and is formed to rotate within the flow space and slide along the flow space.

The first connection portion 142b and the second connection portion 142c are disposed parallel to both sides of the hinge shaft portion 142a and are connected to the base portion 141. In this embodiment, the first connecting portion 142b and the second connecting portion 142c are disposed in parallel in the lateral direction of the housing 110.

On the other hand, so that the actuator 140 can be rotated between the first position (I) and the second position (II), the housing 110 has an opening 117 or a cutout portion 118 communicating with the slot 116 Is equipped. In this embodiment, an opening 117 is provided between the receiving portion 113 and the slot portion 116 to form a space in which the first connection portion 142b is rotatable, and a cutout portion ( It is shown that 118 is provided so that the second connector 142c forms a rotatable space.

In a state in which the actuator 140 is located in the first position (I), an inclined surface 118a may be formed in the cutout 118 to support the second connector 142c that is obliquely disposed to the rear. In a state in which the actuator 140 is located in the first position (I), the insertion part 143 is supported by the metal shell 130, and the flow hinge part 142 is supported by the inclined surface 118a.

On the other hand, the opening 117 is formed to be opened forward for the slide movement of the first connector 142b, and is formed to be opened upward for the rotation of the first connector 142b. Accordingly, the first connector 142b is exposed upward through the opening 117.

Referring to FIG. 8B, in a state in which the actuator 140 is located in the second position (II), the first connection portion 142b is disposed to be spaced apart from the rear end of the opening 117. Accordingly, when the opening 117 is viewed from above, the first connection portion 142b is not completely inserted into the opening 117, so that an empty space is visible in the opening 117.

Referring to FIG. 8C, when the actuator 140 is located in the third position III, the first connector 142b is completely inserted to the rear end of the opening 117. Accordingly, when the opening 117 is viewed from above, the first connection portion 142b is completely inserted into the opening 117, so that an empty space is not visible in the opening 117.

Using this difference, the assembler can check the slide movement state of the flow hinge part 142 based on the position of the first connection part 142b visible through the opening 117 from the upper side of the electrical connector 100. .

On the other hand, as a design modification example, an opening 117 may be provided outside of the slot 116, rather than the cutout 118. In this case, the assembler may check the slide movement state of the flow hinge part 142 based on the position of the second connection part 142c visible through the opening 117.

In addition, as a design modification example, when the first extension part 116a and the second extension part 116b are arranged in parallel in the lateral direction of the housing 110, the first connection part 142b and the second connection part 142c May be disposed parallel to the upper and lower portions of the hinge shaft portion 142a.

Meanwhile, at least one of the first and second connection portions 142b and 142c may be provided with a locking protrusion 142d. The locking protrusion 142d is formed to protrude toward the space between the first connection part 142b and the second connection part 142c, and is formed to be caught in the locking protrusion 116c when the flow hinge part 142 slides. .

In this embodiment, it is shown that the locking protrusion 142d protrudes from the first connection portion 142b.

However, the present invention is not limited thereto. As a design modification example, the locking protrusion 142d may be formed to protrude from the second connection portion 142c, or may be formed to protrude from each of the first and second connection portions 142b and 142c.

In a state in which the actuator 140 is located in the second position (II), the locking protrusion 142d is located in front of the locking protrusion 116c.

In this state, when the actuator 140 slides toward the third position III by receiving an external force, the locking protrusion 142d passes over the locking protrusion 116c by the external force. At this time, the first and second extension portions 116a and 116b or the first and second connection portions 142b and 142c are elastically deformed.

In a state in which the actuator 140 is located in the third position (III), the locking protrusion 142d is located behind the locking protrusion 116c, that is, in the slot 116.

Hereinafter, a structure in which the connection between the cable 1 and the terminal 120 can be stably made even if the cable 1 is less inserted into the receiving portion 113 will be described.

13 is a conceptual diagram showing a slide movement process of the actuator 140 at the bottom of the portion D shown in FIG. 8(b), and FIG. 14 is cut along the line E-E' shown in FIG. It is a conceptual diagram showing the process of moving the slide of (140).

13 and 14, cable insertion guides 143a are provided on both sides of the insertion part 143. The cable insertion guide 143a is formed protruding from the bottom of the insertion part 143, and the actuator 140 is arranged to cover the cable 1 (between the second position (II) and the third position (III). In position), it is inserted into the grooves 1b formed on both sides of the cable 1.

At this time, the groove (1b) of the cable (1) is formed to extend to a certain length along the extension direction of the cable (1), and the cable insertion guide (143a) is formed to be shorter than the length of the groove (1b) formed in the cable (1) do.

When the cable 1 is completely inserted into the receiving portion 113, when the actuator 140 slides, the cable insertion guide 143a is formed to move relative to the groove 1b of the cable 1. At this time, the position of the cable 1 is not moved, and only the cable insertion guide 143a is moved within the groove 1b of the cable 1.

When the cable 1 is less inserted into the receiving part 113, when the actuator 140 slides from the second position (II) to the third position (III), the cable insertion guide 143a is It is formed to be caught in the groove (1b) of 1) to push the cable (1) toward the receiving portion (113). That is, when the actuator 140 slides, the cable insertion guide 143a drags the cable 1 into the receiving portion 113 and enters it. Accordingly, the cable 1 is moved to the correct position of the receiving portion 113 so that the connection with the terminal 120 can be stably made.

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

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

On the other hand, as described above, in a state in which the actuator 140 is located in the third position (III), the locking protrusion 142d is located in the slot 116, and the locking protrusion 116c is in front of the locking protrusion 142d. ) Is located. Therefore, if an external force of more than a preset size is not applied, the locking protrusion 142d is caught by the locking protrusion 116c, and the actuator 140 is not slide-moved forward.

In this way, in a state where the actuator 140 is firmly fixed to the third position (III), a case in which the cable 1 is unintentionally pulled due to a mistake by an assembler may occur. In this case, the groove 1b of the cable 1 is caught by the cable insertion guide 143a, and is formed so that the cable 1 does not come off. Therefore, according to the above structure, connection stability between the cable 1 and the electric connector 100 can be ensured.
