Description

Electrical connector

This creation relates to an electrical connector that electrically connects a wire and a circuit board to form a circuit.

An electronic device is provided with a plurality of electronic components, and in order to electrically connect the electronic components arranged apart from each other, a flexible flat cable (Flexible Flat Cable: FFC), a flexible printed circuit (FPC), etc. are widely used. The flexible flat wire and the flexible printed circuit (hereinafter collectively referred to as "wire") have a structure in which a plurality of terminals are arranged side by side in the width direction at the end of the wire. Such a wire is detachably connected to a connector assembled in a circuit board, and is electrically connected to the circuit board using the connector as a medium.

FIG. 1 is a schematic diagram for explaining the signal reflection phenomenon in the terminal 12 as an example of the electrical connector 10 of the prior art; FIG. 2 is a diagram showing the impedance in the electrical connector 10 shown in FIG. 1.

As shown in FIG. 1, the electrical connector 10 is assembled on the circuit board 2 and is connected to the inserted electric wire 1 to electrically connect the electric wire 1 and the circuit board 2. Such an electrical connector 10 includes a housing 11, terminals 12 arranged in the longitudinal direction of the housing 11, rotatably provided in the housing 11 and formed to fix the electric wire 1 to the terminal 12 in an on state or to release it. The fixed actuator 13 and the fixing nail 14 that fix the housing 11 on the circuit board 2 are described.

The terminal 12 has a soldering portion 12a mounted on the circuit board 2 at the rear end, and a lower arm 12b that branches into contact with the terminal of the electric wire 1 and an upper arm surrounding a part of the rotating shaft 13a of the actuator 13 in front of the soldering portion 12a. The structure of 12c. For reference, in order to guide the support and rotation of the actuator 13, the upper arm of one terminal is configured to surround a part of the rotation shaft 13a, and the upper arm of the other terminal is configured to surround the other part of the rotation shaft 13a.

However, due to the above-mentioned branch structure, there is a problem of signal reflection phenomenon (or even signal eddy current phenomenon) in the terminal 12. Specifically, when the slave circuit board 2 passes through the terminal 12 In the case of transmitting a signal to the electric wire 1, a part of the signal flowing into the terminal 12 through the soldering portion 12a cannot be directly transmitted to the electric wire 1 through the lower arm 12b, and signal reflection occurs while passing through the upper arm 12c.

Referring to FIG. 2, it can be confirmed that the impedance in the electrical connector 10 drops sharply due to the above-mentioned signal reflection phenomenon. The signal reflection phenomenon caused by such a branch structure hinders high-speed signal transmission. Therefore, the electrical connector 10 provided with the branch-type terminal 12 has a problem that it is not suitable for high-speed transmission.

In order to solve the above-mentioned problem, when the design of the terminal 12 is changed to not include the upper arm 12c, a problem occurs that the support and rotation of the actuator 13 cannot be performed smoothly. Therefore, research is being conducted on the electrical connector 10 capable of smoothly supporting and rotating the actuator 13 while reducing the signal reflection phenomenon.

On the other hand, for the stable connection between the electric wire 1 and the terminal 12, the actuator 13 is required to press the electric wire 1 as uniformly as possible. In the prior art, a part of the upper arm 12c of the terminal 12 is formed to support the upper side of the actuator 13, and the actuator 13 is configured to pressurize downward at multiple places. However, in order to prevent the above-mentioned signal reflection phenomenon, if the terminal 12 without the upper arm 12c is applied, since the actuator 13 cannot uniformly pressurize the electric wire 1, the connection between the electric wire 1 and the terminal 12 may not be formed stably.

In addition, the assembler usually looks down on the electrical connector 10 to perform the insertion work of the electric wire 1, and the actuator 13 sometimes blocks the insertion position of the electric wire 1 in the open state. In addition, from the upper side of the electrical connector 10, it is difficult to easily grasp with the naked eye whether the actuator 13 is converted to the fully closed state. Therefore, in order to confirm these assemblers, it is necessary to obliquely observe or observe the electrical connector 10 from the side.

On the other hand, due to assembly errors of the assembler, etc., the electric wire 1 may not be completely inserted into the electrical connector 10. In this case, a problem occurs that the terminal portion of the electric wire 1 and the connecting portion of the terminal 12 are not in contact with each other at a fixed position. Therefore, research is being conducted on a technique capable of correcting such incomplete insertion of the electric wire 1 by the operation of the actuator 13.

Specifically, if the electrical connector 100 is assembled on the circuit board 2, the end of the wire 1 is inserted into the electrical connector 100 when the actuator 140 is in the open state, and then the actuator 140 is closed to form the end of the wire 1. The formed terminal portion 1a and the connecting portion 122a of the terminal 120 are electrically connected.

For reference, the circuit board 2 on which the electrical connector 100 is assembled includes not only the circuit board 2 of rigid material, but also the flexible circuit board of flexible material. In other words, in this embodiment, it is illustrated that the electrical connector 100 is assembled on the rigid circuit board 2, but the invention is not limited to this. It may also be that the electrical connector 100 is assembled on a flexible circuit board to electrically connect the wire 1 and the flexible circuit board.

4 and 5 are exploded views of the structure of the electrical connector 100 shown in FIG. 3 and viewed from different directions; FIG. 6 is a diagram showing the actuator 140 shown in FIG. 3 in an open state and a closed state Schematic diagram of the process of rotating and sliding between state transitions.

Referring to FIGS. 4 to 6 together with the previous FIG. 3, the electrical connector 100 includes a housing 110, a terminal 120, a metal shell 130 and an actuator 140. Here, a plurality of terminals 120 are provided.

The housing 110 constitutes the main body of the electrical connector 100. The housing 110 is arranged long in one direction. The housing 110 is formed of a non-conductive synthetic resin material for electrical insulation of each of the plurality of terminals 120.

A terminal mounting portion 111 and a wire mounting surface 112 are formed in the housing 110.

The terminal mounting portion 111 is formed extending from the rear of the housing 110 toward the front, and forms a space in which the terminal 120 is mounted. The terminal mounting portion 111 is provided with a plurality of terminals for mounting the plurality of terminals 120 respectively, and such a plurality of terminal mounting portions 111 are arranged at a certain interval along the extending direction of the housing 110.

The wire mounting surface 112 forms a surface on which the end of the wire 1 is mounted. The wire mounting surface 112 is formed to extend long in the extending direction of the housing 110.

A part of the terminal mounting portion 111 extending toward the front of the housing 110 is located on the wire mounting surface 112. A part of the terminal mounting portion 111 has a shape recessed in the wire mounting surface 112.

The connecting portion 122 a of the terminal 120 installed in the terminal mounting portion 111 is exposed to the wire mounting surface 112. The connecting portion 122 a is a portion that is connected to the terminal portion 1 a formed in the end of the electric wire 1, and is arranged to protrude from the electric wire mounting surface 112.

The terminal 120 is formed of a conductive metal material, and is installed in the terminal installation portion 111. The terminal 120 includes a welding part 121 and an extension part 122.

The welding part 121 is located behind the rear surface of the housing 110 and is welded to the circuit board 2.

The extension part 122 extends from the welding part 121 and is inserted into the terminal mounting part 111. The extension portion 122 has no branches and extends in the form of a single arm. The extension portion 122 is configured to be inserted into the terminal mounting portion 111 and extend toward the front of the housing 110.

The extension portion 122 includes a connecting portion 122 a protruding from the wire mounting surface 112. The connecting portion 122a may have a curved form for connecting with the terminal portion 1a formed in the end of the electric wire 1.

The metal shell 130 is attached to the housing 110 so as to cover the connecting portion 122a, and a receiving portion 113 is formed between the metal shell 130 and the wire attaching surface 112. The metal shell 130 may be formed of a metal material, such as a stainless steel material (STS, SUS).

The metal shell 130 includes a main body 131 and fixing parts 132 and 133.

The main body 131 extends in one direction and is configured to cover the wire mounting surface 112. The space between the main body 131 and the wire mounting surface 112 forms an insertion portion 143 of the actuator 140 described later and a receiving portion 113 into which the wire 1 is inserted.

The fixing parts 132 and 133 extend from the main body 131 or even protrude, and are formed to be installed on the housing 110 to fix the metal shell 130 to the housing 110.

The fixing parts 132 and 133 include a first fixing part 132.

The first fixing portions 132 are respectively disposed on both sides of the main body 131. The first fixing portion 132 includes a first portion 132 a mounted on the housing 110 and a second portion 132 b mounted on the circuit board 2.

The first part 132 a is bent on both sides of the main body 131 to extend downward, and is inserted into the hole 114 located on the outer side of the accommodating part 113. In this embodiment, the hole 114 is located between the receiving portion 113 and the opening portion 117 described later.

The first portion 132 a may be formed with a clamping portion 132 a ′ engaged with the clamping base 114 a formed in the hole 114. In this embodiment, the chuck table 114a is formed to protrude toward the front of the housing 110, and the chuck portion 132a' has a shape corresponding to the chuck table 114a that is recessed toward the front at the rear end.

A fixing protrusion (not shown) may be provided on one side of the first portion 132a forming the card portion 132a'. The fixing protrusion is formed in a sharp shape, and if the card portion 132a' is engaged with the card table 114a, it is inserted into the card table 114a, so that the card portion 132a' does not easily fall off from the card table 114a.

The second part 132 b is formed to be bent at the first part 132 a and exposed to the bottom surface of the housing 110, and is assembled to the circuit board 2.

The second portion 132b may have a form extending toward the inner side or the outer side of the receiving part 113. In this embodiment, the second portion 132b has a form extending toward the outside of the accommodating portion 113, and is arranged such that a part of the second portion 132b and the opening portion 117 adjacent to the hole 114 overlap in the thickness direction of the housing 110.

The fixing parts 132 and 133 may further include a second fixing part 133.

The second fixing portion 133 is located between the first fixing portions 132 extending on both sides of the main body 131 and protrudes from the rear end side of the main body 131 to be inserted into the housing 110. At least one second fixing part 133 is provided. In this embodiment, a plurality of second fixing parts 133 are provided and arranged at a certain interval.

A hole 115 capable of engaging with the second fixing portion 133 is formed in the housing 110. In this embodiment, it is shown that a plurality of holes 115 are formed in the rear wall of the housing 110 at certain intervals. The hole 115 is located on the upper side of the terminal mounting portion 111.

In this way, when the metal shell 130 is mounted on the housing 110 to form the housing portion 113, a structure in which the actuator 140 is completely inserted into the housing portion 113 and uniformly pressurizes the upper portion of the actuator 140 can be realized in a compact size. If the housing 110 is extended to form a portion of the metal shell 130, in order to achieve a structure that uniformly pressurizes the upper portion of the actuator 140 to the same degree as the metal shell 130, the thickness of the metal shell 130 portion needs to be quite thick. Therefore, according to the present structure using the metal shell 130, it is possible to realize a compact electrical connector 100 that can ensure contact reliability under height restrictions.

The actuator 140 is rotatably and slidably disposed on the housing 110, and is formed to be inserted into the accommodating portion 113 during the sliding. The actuator 140 is formed of a non-conductive synthetic resin material.

6, the actuator 140 is formed to be able to rotate between a first position I where the insertion portion 143 is located on the metal shell 130 and a second position II where the insertion portion 143 is located in front of the receiving portion 113. In addition, the actuator 140 is formed to be able to slide between the second position II and the third position III where the insertion portion 143 is inserted into the accommodating portion 113.

When the actuator 140 is in the first position I, the actuator 140 is equivalent to the open state, and when the actuator 140 is in the third position III, the actuator 140 is equivalent to the closed state.

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

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

The actuator 140 includes a base portion 141, a living hinge portion 142 and an insertion portion 143.

The base portion 141 is formed to extend long in the length direction of the housing 110.

The living hinge part 142 is formed protrudingly on both sides of the base part 141 and is rotatably and slidably disposed on the housing 110. For the rotation and sliding movement of the actuator 140, slots 116 are formed on both sides of the housing 110 to extend long in the front-rear direction of the housing 110.

The insertion portion 143 protrudes from the base portion 141 between the two living hinge portions 142 spaced apart from each other, and is formed to be inserted into the receiving portion 113 or pulled out from the receiving portion 113 when sliding.

Fig. 7 is a perspective view showing the rotation and sliding process of the actuator 140 shown in Fig. 6; Fig. 8 is a plan view showing the rotation and sliding process of the actuator 140 shown in Fig. 6; Fig. 9 is a view along the way A cross-sectional view taken along the line AA' shown in 8 to show the rotation and sliding process of the actuator 140, and FIG. 10 is a side view showing the rotation and sliding process of the actuator 140 shown in FIG. 6 view.

Referring to (a) of each of the above figures, in a state where the actuator 140 is located at the first position I, the accommodating portion 113 is in a state of being opened toward the front. That is, it becomes a state in which the electric wire 1 can be inserted into the accommodating portion 113.

8(a), in a state where the actuator 140 is located at the first position I, the actuator 140 is configured so as not to cover the metal shell 130, specifically the front end of the main body 131, in the thickness direction of the housing 110. That is, the actuator 140 in the first position I is arranged in a state of being tilted backward so that the front side of the metal shell 130 can be seen from the upper side.

At this time, the actuator 140, specifically the base portion 141, may be in contact with the metal shell 130. That is, the metal shell 130 is formed to support the actuator 140, specifically the base portion 141.

7(a) and 10(a), the living hinge portion 142 of the actuator 140 is arranged to be inclined rearward. That is, the first and second connecting portions 142b and 142c described later extend obliquely rearward from the hinge shaft portion 142a and are connected to the base portion 141.

According to the configuration, the visual field of the assembler who looks down at the electrical connector 100 and connects the electric wire 1 to the electrical connector 100 is not blocked by the actuator 140. Therefore, the assembler can easily confirm whether the electric wire 1 is inserted into the fixed position of the accommodating portion 113 from the upper side of the electrical connector 100 with the naked eye.

When the electric wire 1 is inserted into a fixed position in the accommodating portion 113, the electric wire 1 is positioned on the electric wire mounting surface 112, and the terminal portion 1 a of the electric wire 1 is arranged to overlap the connecting portion 122 a of the terminal 120. However, even though the terminal portion 1a is mounted on the connecting portion 122a, stable energization is not formed.

On the other hand, the metal shell 130, specifically the main body 131, may be configured to completely cover the connecting portion 122a in the thickness direction of the housing 110. For reference, referring to FIG. 9(c), the main body 131 of the metal shell 130, the insertion portion 143 of the actuator 140, the terminal portion 1a of the wire 1 and the connecting portion 122a of the terminal 120 are arranged in the electrical connector 100 The thickness direction overlaps. This is a structure for the main body 131 to cover and support the upper side of the insertion portion 143 so that the terminal portion 1a is firmly in contact with the connecting portion 122a.

The actuator 140 located in the first position I is moved to the second position II by rotation.

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

At this time, as shown in the figure, the insertion portion 143 and the metal shell 130 are arranged at a certain interval, and a part of the electric wire 1 is exposed from the gap created by the interval.

7(b) and 10(b), the living hinge portion 142 of the actuator 140 is arranged in the slot 116 side by side. That is, the first and second connecting portions 142b and 142c described later extend forward from the hinge shaft portion 142a and are connected to the base portion 141.

The actuator 140 in the second position II moves to the third position III by sliding.

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

If the insertion portion 143 is completely inserted into the accommodating portion 113, the insertion portion 143 makes the wire 1 abut on the wire mounting surface 112. In this process, the terminal portion 1a of the wire 1 and the terminal 120 exposed from the wire mounting surface 112 The connecting portion 122a is in contact. At this time, the metal shell 130 covers and supports the upper side of the insertion portion 143, so that the connection between the terminal portion 1a and the connecting portion 122a can be stably maintained.

In the structure of fixing the metal shell 130 to the housing 110, that is, the above-mentioned fixing portion 132 is only provided on both sides of the metal shell 130 (in this embodiment, corresponding to the first fixing portion 132), the metal The middle part of the shell 130 covers and supports the upper side of the insertion part 143 with weak force, which may cause a terminal The connection between the portion 1a and the connection portion 122a is poor. Such a phenomenon is that the longer the electrical connector 100 is formed, the more likely it is to occur.

At this time, if the above-mentioned fixing portion 133 (corresponding to the second fixing portion 133 in this embodiment) is additionally formed at a certain interval along the longitudinal direction of the metal shell 130, it can be located in the middle portion of the metal shell 130. The upper side of the insertion portion 143 is also strongly supported to prevent poor connection between the terminal portion 1a and the connecting portion 122a.

And, referring to FIG. 7(c) and FIG. 10(c), the living hinge portion 142 of the actuator 140 moves to the rear along the slot 116. That is, the hinge shaft portion 142a described later moves in the slot 116 toward the rear end portion.

Under the operation of the actuator 140 described above, the insertion portion 143 is an important structure for stable connection between the terminal portion 1 a of the electric wire 1 and the connection portion 122 a of the terminal 120. Only the operation of the insertion portion 143 is disassembled and observed. The insertion portion 143 is moved between the first position I located on the metal shell 130 and the second position II located in front of the accommodating portion 113 by the rotation of the actuator 140. The sliding movement of the device 140 moves between the second position II and the third position III inserted into the receiving portion 113.

On the other hand, if the insertion portion 143 is completely inserted into the accommodating portion 113, it can be formed that the actuator 140 is locked to the housing 110. That is, it may be formed such that the actuator 140 does not fall off in the opposite direction.

Hereinafter, the structure for realizing the rotation and sliding movement of the actuator 140 and the locking structure of the actuator 140 will be described in more detail.

FIG. 11 is a perspective view showing part B shown in (b) of FIG. 7; FIG. 12 is a schematic diagram taken along the line CC' shown in FIG. 11 to show the sliding process of the actuator 140.

11 and 12, slots 116 are provided on both sides of the accommodating portion 113 so that the living hinge portion 142 can be inserted and rotated and slidably moved. The slot 116 is formed to extend long in the front-rear direction of the housing 110.

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

The first extension portion 116a and the second extension portion 116b extend from the rear side of the housing 110 toward the front to face each other, forming a movable space into which the living hinge portion 142 can be inserted and can be rotated and slid.

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

However, this creation is not limited to this. As a design variation, the first extension 116a and the second extension 116b may be arranged in parallel in the lateral direction of the housing 110. In this case, the first extension 116a and the second extension 116b respectively form the left and right sides of the slot 116.

The hook protrusion 116c is formed to protrude from the front side of at least one of the first and second extension portions 116a, 116b toward the movable space between the first extension portion 116a and the second extension portion 116b, and defines the movable space. Here, limiting the movable space means that the movement of the hinge shaft portion 142a of the movable hinge portion 142 described later is restricted by the hook protrusion 116c.

In this embodiment, it is shown that a hook protrusion 116c is protrudingly formed in each of the first and second extension portions 116a, 116b.

But this creation is not limited to this. As a design modification example, the hook protrusion 116c may be protrudingly formed on only any one of the first and second extension portions 116a and 116b.

The living 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 disposed in the movable space, and is formed to be able to rotate in the movable space and slide along the movable space.

The first connection portion 142b and the second connection portion 142c are arranged in parallel on 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 arranged in parallel in the lateral direction of the housing 110.

On the other hand, the housing 110 is provided with an opening portion 117 and even a cutting portion 118 communicating with the slot 116, so that the actuator 140 can rotate between the first position I and the second position II. In this embodiment, it is shown that an opening 117 is provided between the accommodating portion 113 and the slot 116 to form a rotatable space for the first connecting portion 142b, and a cutting portion 118 is provided on the outside of the slot 116 to form a second connecting portion 142c. Rotatable space.

An inclined surface 118a may be formed in the cutting portion 118 so as to support the second connecting portion 142c arranged obliquely backward when the actuator 140 is located at the first position I. In a state where the actuator 140 is located at the first position I, the insertion portion 143 is supported by the metal shell 130, and the living hinge portion 142 is supported by the inclined surface 118a.

On the other hand, the opening portion 117 is formed to open forward for the sliding movement of the first connecting portion 142b, and to open upward for the rotation of the first connecting portion 142b. Therefore, the first connection portion 142b is exposed to the upper side through the opening portion 117.

Referring to FIG. 8( b ), in a state where the actuator 140 is located at the second position II, the first connection portion 142 b is arranged to be spaced apart from the rear end of the opening portion 117. Therefore, when the opening portion 117 is viewed from the upper side, since the first connection portion 142b is not completely inserted into the opening portion 117, the hollow space of the opening portion 117 can be seen.

Referring to FIG. 8( c ), in a state where the actuator 140 is located at the third position III, the first connecting portion 142 b is completely inserted to the rear end of the opening portion 117. Therefore, when the opening portion 117 is viewed from the upper side, the first connection portion 142b is completely inserted into the opening portion 117, and the empty space in the opening portion 117 is not seen.

Using such a difference, the assembler can confirm the sliding state of the living hinge portion 142 based on the position of the first connecting portion 142 b seen from the upper side of the electrical connector 100 through the opening portion 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 cutting part 118. In this case, the assembler can also determine the sliding state of the living hinge portion 142 based on the position of the second connecting portion 142c seen through the opening portion 117.

In addition, as a design variation, in the case where the first extension 116a and the second extension 116b are arranged in parallel in the lateral direction of the housing 110, the first connection portion 142b and the second connection portion 142c may also be positioned on the hinge axis. The upper part and the lower part of the part 142a are arrange|positioned in parallel.

On the other hand, at least one of the first and second connecting portions 142b, 142c may be provided with a locking protrusion 142d. The locking protrusion 142d is formed to protrude toward the space between the first connecting portion 142b and the second connecting portion 142c, and is formed to be able to engage with the hook protrusion 116c when the living hinge portion 142 slides.

In this embodiment, it is shown that a locking protrusion 142d is protrudingly formed on the first connecting portion 142b.

But this creation is not limited to this. As a design variation, the locking protrusion 142d may be formed protrudingly in the second connecting portion 142c, or may be formed protruding in each of the first and second connecting portions 142b and 142c.

When the actuator 140 is in the second position II, the locking protrusion 142d is located in front of the hook protrusion 116c.

In this state, when the actuator 140 receives an external force and slides toward the third position III, the locking protrusion 142d passes over the hook 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.

When the actuator 140 is at the third position III, the locking protrusion 142d is located behind the hook protrusion 116c, that is, in the slot 116.

Hereinafter, a structure in which the electric wire 1 and the terminal 120 can be connected stably even if the electric wire 1 is not completely inserted into the accommodating portion 113 will be described.

Fig. 13 is a schematic diagram showing the sliding process of the actuator 140 from the bottom of part D shown in Fig. 8(b); Fig. 14 is taken along the line E-E' shown in Fig. 13 to show A schematic diagram of the sliding process of the actuator 140.

Referring to FIGS. 13 and 14, wire insertion guides 143 a are provided on both sides of the insertion portion 143. The wire insertion guide 143a is protrudingly formed at the bottom of the insertion portion 143, and is inserted into the wire 1 in a state in which the actuator 140 is configured to cover the wire 1 (the state between the second position II and the third position III) Slots 1b formed on both sides.

At this time, the groove 1 b of the electric wire 1 is formed to extend with a certain length along the extending direction of the electric wire 1, and the electric wire insertion guide 143 a is formed to be shorter than the length of the groove 1 b formed in the electric wire 1.

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

When the electric wire 1 is not completely inserted into the accommodating portion 113, when the actuator 140 slides from the second position II to the third position III, the electric wire insertion guide 143a is formed to be engaged with the groove 1b of the electric wire 1 to hold the electric wire 1 Push toward the accommodating part 113. That is, when the actuator 140 slides, the wire insertion guide 143a pulls the wire 1 into the accommodating portion 113. Therefore, the electric wire 1 is moved to the fixed position of the accommodating portion 113, and the connection with the terminal 120 can be formed stably.

In a state where the actuator 140 is at the third position III, the electric wire 1 is completely inserted into the accommodating portion 113, and the electric wire insertion guide 143a contacts the end of the groove 1b. At this time, the electric wire insertion guide 143a no longer pushes the electric wire 1.

The wire installation surface 112 is formed with a wire insertion groove 119 into which the wire insertion guide 143a is inserted. The wire insertion groove 119 is arranged on the outside of the terminal mounting portion 111.

On the other hand, as described above, when the actuator 140 is in the third position III, the locking projection 142d is located in the slot 116, and the hook projection 116c is located in front of the locking projection 142d. Therefore, unless an external force greater than the set level is applied, the locking protrusion 142d is engaged with the hook protrusion 116c, and the actuator 140 is not slid forward.

In this way, in a state where the actuator 140 is firmly fixed at the third position III, due to an assembler's error or the like, the electric wire 1 may be pulled unexpectedly. In this case, the groove 1b of the electric wire 1 is engaged with the electric wire insertion guide 143a, so that the electric wire 1 is not detached. Therefore, according to the structure, the connection stability between the electric wire 1 and the electrical connector 100 can be ensured.
