Description

Electrical connector

Technical Field

The utility model relates to an electric connector which connects an electric wire and a circuit board to form a circuit.

Background

In order to electrically connect electronic components arranged at a distance from each other, a Flexible Flat Cable (FFC), a Flexible Printed Circuit (FPC), or the like is 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 electric wires are detachably connected to a connector fitted in the circuit board and electrically connected to the circuit board with the connector as a medium.

Fig. 1 is a schematic diagram for explaining a signal reflection phenomenon at a terminal 12 as an example of a conventional electrical connector 10, and fig. 2 is a graph showing impedance in the electrical connector 10 shown in fig. 1.

As shown in fig. 1, the electrical connector 10 is mounted 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 a longitudinal direction of the housing 11, an actuator 13 rotatably provided to the housing 11 and formed to fix or release the electric wires 1 to or from the terminals 12 in a connected state, and fixing claws (fixing tails) 14 fixing the housing 11 to the circuit board 2.

The terminal 12 has a solder portion 12a attached to the circuit board 2 at the rear end, and has a structure in which a lower arm 12b branched to be in contact with the terminal of the electric wire 1 and an upper arm 12c surrounding a part of a rotation shaft 13a of the actuator 13 are provided in front of the solder portion 12 a. For reference, in order to guide the support and rotation of the actuator 13, the upper arm of one terminal is configured to surround one 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 13 a.

However, due to the above-described branching structure, there is a problem that a reflection phenomenon of a signal (or even an eddy current phenomenon of a signal) is generated in the terminal 12. Specifically, in the case of transmitting a signal from the circuit board 2 to the electric wire 1 through the terminal 12, 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, causing signal reflection while passing through the upper arm 12 c.

Referring to fig. 2, it can be confirmed that the impedance in the electrical connector 10 is sharply decreased due to the signal reflection phenomenon described above. The signal reflection phenomenon due to such a branching structure hinders high-speed transmission of signals, and therefore the electrical connector 10 including the branch-type terminal 12 has a problem that it is not suitable for high-speed transmission.

In order to solve the above problem, if the terminal 12 is designed without the upper arm 12c, the support and rotation of the actuator 13 cannot be smoothly performed. Therefore, research has been conducted on the electrical connector 10 that can reduce the signal reflection phenomenon and can smoothly support and rotate the actuator 13.

On the other hand, in order to stably connect the electric wire 1 and the terminal 12, the actuator 13 is required to uniformly pressurize the electric wire 1 to the maximum. In the related art, the upper arm 12c of a part of the terminals 12 is formed to support the upper side of the actuator 13, and the actuator 13 is configured to be pressed downward at a plurality of places. However, if the terminal 12 without the upper arm 12c is applied in order to prevent the signal reflection phenomenon, the actuator 13 cannot uniformly pressurize the electric wire 1, and thus the connection between the electric wire 1 and the terminal 12 may not be stably formed.

The assembler usually performs the insertion operation of the electric wire 1 by looking down the electric connector 10, and the actuator 13 may block the insertion position of the electric wire 1 in the open state. In addition, it is difficult to visually grasp whether or not the actuator 13 is switched to the fully closed state from the upper side of the electrical connector 10. Therefore, there is an inconvenience that the assembler needs to observe the electrical connector 10 obliquely or from a side direction in order to confirm the same.

On the other hand, there may be a case where the electric wire 1 is not completely inserted into the electric connector 10 due to an assembly error of an assembler or the like. In this case, a problem occurs in that the terminal portion of the electric wire 1 and the contact portion of the terminal 12 do not contact at a fixed position. Therefore, a technique capable of correcting such incomplete insertion of the electric wire 1 by the operation of the actuator 13 has been studied.

The background art of the present invention is disclosed in japanese laid-open patent publication No. 2013-175395 (09/05/2013).

In order to achieve the second object of the present invention, the metal shell is formed to cover and support an upper side of the insertion portion so that the insertion portion presses the electric wire toward the through portion at the third position where the electric wire is mounted on the electric wire mounting surface.

In order to achieve the third object of the present invention, in the first position, the actuator is disposed to be inclined rearward and is disposed so as not to cover a front end portion of the metal shell in a thickness direction of the housing.

Furthermore, the utility model discloses an electric connector, include: a housing having a terminal mounting portion and an electric wire mounting surface; a terminal mounted on the terminal mounting portion and having a connection portion exposed to the wire mounting surface; a metal shell mounted to the housing to cover the through portion and forming an accommodating portion with the electric wire mounting surface; and an actuator provided to the housing, the actuator including: a base; the movable hinge part is formed by protruding two sides of the base and is arranged on the shell in a rotating and sliding way; and an insertion part protruding from the base between the movable hinge parts formed at both sides of the base and inserted into or pulled out of the accommodation part when the sliding movement is performed.

The wire insertion guide is formed to protrude from the bottom of the insertion portion, and a wire insertion groove into which the wire insertion guide is inserted is formed in the wire attachment surface.

The effect of the utility model obtained through foretell solution is as follows.

First, in the present invention, the actuator is rotatably and slidably disposed in the insertion grooves formed in both sides of the accommodating portion. Therefore, it is possible to eliminate a portion that rotatably supports the actuator in the existing terminal, which is configured to have only a single arm of a portion for transmitting a signal. As a result, the phenomenon of signal reflection and the resulting impedance drop in the electrical connector can be prevented. The electric connector of the present invention can be used for high-speed transmission smoothly.

Second, in a state where the actuator is located at the third position, the metal shell covers and supports an upper side of the insertion portion inserted in the accommodation portion. Therefore, the insertion portion presses the electric wire toward the connection portion, and the electric wire can be held in a state where the electric wire is firmly connected to the connection portion.

Third, the actuator at the first position is disposed at the upper side in a state of being tilted backward to the front side of the metal shell, so that an assembler can easily confirm whether or not the electric wire is inserted into the fixed position of the housing portion from the upper side of the electric connector. In addition, since the opening is formed such that a part of the movable hinge portion is exposed, an assembler can easily confirm whether or not the actuator has completely moved from the second position to the third position from the upper side of the electrical connector.

Fourth, even if the electric wire is not completely inserted into the accommodating part, the electric wire is drawn into the accommodating part by the electric wire insertion guides inserted into the grooves at both sides of the electric wire when the actuator slips. Therefore, the electric wire is moved to the fixed position of the housing portion, and the connection with the terminal can be stably made.

Fig. 3 is a perspective view illustrating an electrical connector 100 according to an embodiment of the present invention.

Referring to fig. 3, the electrical connector 100 is configured to electrically connect the circuit board 2 and the electric wire 1 to constitute an electric circuit. Specifically, when the electrical connector 100 is mounted on the circuit board 2, and the actuator 140 is closed after the end portion of the electric wire 1 is inserted into the electrical connector 100 with the actuator 140 in the open state, electrical contact is formed between the terminal portion 1a formed at the end portion of the electric wire 1 and the contact portion 122a of the terminal 120.

For reference, the circuit board 2 to which the electrical connector 100 is mounted includes not only the circuit board 2 of a rigid material but also a flexible circuit board of a flexible material. In other words, in the present embodiment, the electrical connector 100 is illustrated as being mounted on the rigid circuit board 2, but the present invention is not limited thereto. The electrical connector 100 may be mounted on a flexible circuit board to electrically connect the electric wire 1 to the flexible circuit board.

Fig. 4 and 5 are views, which are exploded and viewed from different directions, of the electrical connector 100 shown in fig. 3, and fig. 6 is a schematic view showing a process in which the actuator 140 shown in fig. 3 rotates and slides in order to make a state transition between an open state and a closed state.

Referring to fig. 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, the terminal 120 is provided in plurality.

The housing 110 constitutes a 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.

Terminal mounting portions 111 and wire mounting surfaces 112 are formed in the housing 110.

The terminal mounting portion 111 is formed to extend forward from the rear surface portion of the housing 110, and forms a space where the terminal 120 is mounted. The terminal mounting portions 111 are provided in plural to mount the plural terminals 120, respectively, and such plural terminal mounting portions 111 are arranged at intervals along the extending direction of the housing 110.

The wire attachment surface 112 is a surface to which an end of the wire 1 is attached. The wire attachment surface 112 is formed to extend long in the extending direction of the housing 110.

A portion of the terminal mounting portion 111 extending forward of the housing 110 is located on the wire mounting surface 112. A part of the terminal mounting portion 111 has a form recessed in the electric wire mounting face 112.

The turn-on portions 122a of the terminals 120 mounted in the terminal mounting portion 111 are exposed to the wire mounting face 112. The through portion 122a is a portion that is in contact with a terminal portion 1a formed in an end portion 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 mounted to the terminal mounting portion 111. The terminal 120 includes a soldering portion 121 and an extending portion 122.

The soldering portion 121 is located behind the rear surface of the housing 110 and soldered to the circuit board 2.

The extending portion 122 extends from the soldering portion 121 and is inserted into the terminal mounting portion 111. The extension 122 is unbranched extending in a single-armed configuration. The extension portion 122 is configured to be inserted into the terminal mounting portion 111 and extend forward of the housing 110.

The extension portion 122 includes a through portion 122a projecting from the wire attachment surface 112. The through portion 122a may have a bent shape for making contact with the terminal portion 1a formed in the end portion of the electric wire 1.

The metal shell 130 is attached to the housing 110 so as to cover the through portion 122a, and forms an accommodating portion 113 with the wire attachment surface 112. The metal case 130 may be formed of a metal material, for example, stainless steel material (STS, SUS).

The metal shell 130 includes a main body 131 and fixing

portions

132, 133.

The body 131 extends in one direction and is disposed so as to cover the wire mounting surface 112. The space between the body 131 and the wire attachment surface 112 forms an insertion portion 143 of an actuator 140 described later and an accommodation portion 113 into which the wire 1 is inserted.

The fixing

portions

132 and 133 extend or protrude from the body 131, and are formed to be attached to the housing 110 to fix the metal shell 130 to the housing 110.

The fixing

portions

132, 133 include a first fixing portion 132.

The first fixing portions 132 are respectively disposed at two sides of the body 131. The first fixing portion 132 includes a first portion 132a attached to the housing 110 and a second portion 132b attached to the circuit board 2.

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

A locking portion 132a' that engages with a locking boss 114a formed in the hole 114 may be formed in the first portion 132 a. In the present embodiment, the locking stand 114a is formed to protrude toward the front of the housing 110, and the locking portion 132a' has a shape corresponding to the locking stand 114a recessed toward the front at the rear end.

A fixing protrusion (not shown) may be provided at one side of the first portion 132a forming the catching portion 132 a'. The fixing projection is formed in a sharp shape, and when the engaging portion 132a 'engages with the engaging base 114a, the fixing projection is inserted into the engaging base 114a, so that the engaging portion 132a' is not easily detached from the engaging base 114 a.

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

The second portion 132b may have a shape extending toward the inside or the outside of the receiving portion 113. In the present embodiment, the second portion 132b extends outward of the housing portion 113, and is disposed such that a part of the second portion 132b overlaps the opening 117 adjacent to the hole 114 in the thickness direction of the housing 110.

The fixing

portions

132, 133 may further include a second fixing portion 133.

The second fixing portion 133 is located between the first fixing portions 132 formed to extend on both sides of the body 131, and protrudes from the rear end side of the body 131 to be inserted into the housing 110. The second fixing portion 133 is provided with at least one. In the present embodiment, the second fixing portion 133 is provided in plurality and disposed at a certain interval.

The housing 110 has a hole 115 into which the second fixing portion 133 can be engaged. In the present embodiment, a plurality of holes 115 are shown to be formed at intervals in the rear wall of the housing 110. The hole 115 is located at an upper side of the terminal mounting portion 111.

In this way, when the metal shell 130 is attached to the housing 110 to form the accommodating portion 113, a structure in which the upper side of the actuator 140 is uniformly pressurized in a state in which the actuator 140 is completely inserted into the accommodating portion 113 can be achieved in a slim manner. If the case 110 is extended to form the metal shell 130 portion, the thickness of the metal shell 130 portion needs to be considerably thick in order to realize a structure that uniformly pressurizes the upper side of the actuator 140 to the same extent as the metal shell 130. Therefore, according to the present structure using the metal shell 130, the slim electrical connector 100 capable of securing contact reliability under height restriction can be realized.

The actuator 140 is rotatably and slidably provided to the housing 110, and is formed to be insertable into the accommodating portion 113 when slidably moved. The actuator 140 is formed of a non-conductive synthetic resin material.

Referring to fig. 6, the actuator 140 is formed to be rotatable between a first position i where the insertion portion 143 is positioned on the metal shell 130 and a second position ii where the insertion portion 143 is positioned in front of the accommodating portion 113. The actuator 140 is formed to be slidable between the second position ii and a third position iii at which the insertion portion 143 is inserted into the housing portion 113.

When the actuator 140 is in the first position i, the actuator 140 corresponds to an open state, and when the actuator 140 is in the third position iii, the actuator 140 corresponds to a closed state.

The actuator 140 rotates and slips when switching from the open state to the closed state, and rotates after slipping when switching from the closed state to the open state.

In the open state, the electric wire 1 can be inserted into the accommodation portion 113 and positioned on the electric wire mounting surface 112, and in the closed state, a part of the actuator 140 (the insertion portion 143) is inserted into the accommodation portion 113 and the electric wire 1 is closely fixed to the electric wire mounting surface 112. At this time, the through portion 122a of the terminal 120 is in contact with the terminal portion 1a of the electric wire 1.

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

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

The movable hinge portion 142 is formed to protrude at both sides of the base portion 141 and is rotatably and slidably provided to the housing 110. For rotation and sliding of the actuator 140, insertion grooves 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 movable hinge portions 142 arranged to be spaced apart from each other, and is formed to be inserted into or pulled out from the receiving portion 113 while sliding.

Fig. 7 is a perspective view illustrating a rotation and slip process of the actuator 140 illustrated in fig. 6, fig. 8 is a plan view illustrating the rotation and slip process of the actuator 140 illustrated in fig. 6, fig. 9 is a sectional view illustrating the rotation and slip process of the actuator 140 taken along a line a-a' illustrated in fig. 8, and fig. 10 is a side view illustrating the rotation and slip process of the actuator 140 illustrated in fig. 6.

Referring to fig. (a) of the above drawings, 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, the electric wire 1 is inserted into the accommodating portion 113.

Referring to fig. 8 (a), in a state where the actuator 140 is located at the first position i, the actuator 140 is arranged not to cover the metal shell 130, specifically, the front end portion 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 to the front side of the metal shell 130 as viewed from the upper side.

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

Referring to fig. 7 (a) and 10 (a), the movable hinge 142 of the actuator 140 is disposed to be inclined rearward. That is, first and second connecting

portions

142b and 142c, which will be described later, extend obliquely rearward from the hinge shaft portion 142a and are connected to the base portion 141.

According to the configuration, the field of view of an assembler who views the electrical connector 100 downward to connect the electric wire 1 to the electrical connector 100 is not obstructed by the actuator 140. Therefore, the assembler can easily confirm with the naked eye whether or not the electric wire 1 is inserted into the fixed position of the housing portion 113 from the upper side of the electric connector 100.

When the electric wire 1 is inserted into the housing portion 113 at a fixed position, the electric wire 1 is positioned on the electric wire mounting surface 112, and the terminal portion 1a of the electric wire 1 is arranged to overlap the contact portion 122a of the terminal 120. However, although the terminal portion 1a is mounted on the through portion 122a, stable conduction is not formed.

On the other hand, the metal shell 130, specifically, the body 131 may be configured to completely cover the through portion 122a in the thickness direction of the case 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 electric wire 1, and the contact portion 122a of the terminal 120 are arranged to overlap in the thickness direction of the electrical connector 100. This is a structure in which the main body 131 covers and supports the upper side of the insertion portion 143, and the terminal portion 1a is firmly contacted to the through portion 122 a.

The actuator 140 in the first position i is moved by rotation to the second position ii.

Referring to fig. (b) of the above drawings, in a state where the actuator 140 is located at the second position ii, the actuator 140 is disposed in front of the accommodating portion 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 with the terminal portion 1a of the electric wire 1 and the contact portion 122a of the terminal 120 in the thickness direction of the electrical connector 100.

At this time, as shown in the drawing, the insertion portion 143 and the metal shell 130 are arranged to be spaced apart by a certain interval, and a part of the electric wire 1 is exposed from a gap generated by the spacing.

Referring to fig. 7 (b) and 10 (b), the movable hinge portion 142 of the actuator 140 is disposed side by side in the slot 116. That is, 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 in the second position ii is moved by sliding movement to the third position iii.

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 accommodation 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 through portion 122 a.

If the insertion portion 143 is completely inserted into the accommodation portion 113, the insertion portion 143 brings the electric wire 1 into close contact with the electric wire installation surface 112, in which process the terminal portion 1a of the electric wire 1 contacts the contact portion 122a of the terminal 120 exposed from the electric wire installation surface 112. At this time, since metal shell 130 covers and supports the upper side of insertion portion 143, it is possible to stably maintain the connection between terminal portion 1a and via portion 122 a.

In the case of the structure of fixing the metal shell 130 to the housing 110, that is, 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 the present embodiment), the force of covering and supporting the upper side of the insertion portion 143 in the middle portion of the metal shell 130 is weak, and a connection failure between the terminal portion 1a and the connection portion 122a may occur. This phenomenon is likely to occur as the electrical connector 100 is extended longer.

In this case, if the fixing portions 133 (corresponding to the second fixing portions 133 in the present embodiment) are additionally formed at a predetermined interval in the longitudinal direction of the metal shell 130, the upper side of the insertion portion 143 can be strongly supported also in the middle portion of the metal shell 130, and a connection failure between the terminal portion 1a and the connection portion 122a can be prevented.

Referring to fig. 7 (c) and 10 (c), the movable 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 toward the rear end portion in the slot 116.

The insertion portion 143 is an important structure for stable connection between the terminal portion 1a of the electric wire 1 and the connection portion 122a of the terminal 120 by the operation of the actuator 140. Only the operation of the insertion portion 143 is disassembled and observed, and the insertion portion 143 moves between a first position i located on the metal shell 130 and a second position ii located in front of the accommodation portion 113 by the rotation of the actuator 140, and moves between the second position ii and a third position iii inserted into the accommodation portion 113 by the sliding movement of the actuator 140.

On the other hand, if the insertion portion 143 is completely inserted into the accommodation portion 113, the actuator 140 may be locked to the housing 110. That is, the actuator 140 may not be detached in the opposite direction.

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

Fig. 11 is a perspective view illustrating a portion B shown in (B) of fig. 7, and fig. 12 is a schematic view taken along a line C-C' shown in fig. 11 to illustrate a slipping process of the actuator 140.

Referring to fig. 11 and 12, insertion grooves 116 into which the movable hinge portions 142 are inserted to be rotatable and slidable are provided at both sides of the accommodating portion 113. The insertion groove 116 is formed to extend long in the front-rear direction of the housing 110.

The socket 116 includes a first extension 116a, a second extension 116b, and a hooking protrusion 116 c.

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 movable hinge portion 142 is inserted and is rotatable and slidable.

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

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

The hooking protrusion 116c is formed to protrude toward the active space between the first extension 116a and the second extension 116b at a front side of at least one of the first and

second extensions

116a, 116b, defining the active space. Here, defining 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 hooking protrusion 116 c.

In the present embodiment, a hooking protrusion 116c is shown to be formed in each of the first and second extending

portions

116a, 116 b.

The present invention is not limited thereto. As an example of the design variation, the hooking protrusion 116c may be formed only in one of the first and second extending

portions

116a and 116 b.

The movable hinge portion 142 includes a hinge shaft portion 142a, a first connection portion 142b, and a second connection portion 142 c.

The hinge shaft portion 142a is disposed in the movable space, and is formed to be rotatable in the movable space and slidable along the movable space.

The first connecting portion 142b and the second connecting portion 142c are disposed 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 connection portion 142b and the second connection portion 142c are arranged in parallel in the side direction of the housing 110.

On the other hand, the housing 110 is provided with an opening 117 and a cut-out 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, the opening 117 is provided between the accommodating portion 113 and the slot 116 to form a space in which the first connecting portion 142b is rotatable, and the cut portion 118 is provided outside the slot 116 to form a space in which the second connecting portion 142c is rotatable.

The inclined surface 118a may be formed in the cut portion 118 so as to support the second connection portion 142c, which is obliquely arranged rearward, in a state where 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 movable hinge portion 142 is supported by the inclined surface 118 a.

On the other hand, the opening 117 is formed to open forward for sliding movement of the first connection portion 142b, and also to open upward for rotation of the first connection portion 142 b. 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 142b is disposed to be spaced apart from the rear end of the opening 117. Therefore, when the opening 117 is viewed from the upper side, since the first connection portion 142b is not completely inserted into the opening 117, a hollow space of the opening 117 is seen.

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

With such a difference, the assembler can confirm the sliding state of the movable hinge portion 142 based on the position of the first connection portion 142b viewed from the upper side of the electrical connector 100 through the opening 117.

On the other hand, as a variation of the design, the opening 117 may be provided outside the slot 116 instead of the cut portion 118. In this case, the assembler may determine the sliding state of the movable hinge portion 142 based on the position of the second connection portion 142c viewed through the opening 117.

In addition, as an example of the design, when the first extending portion 116a and the second extending portion 116b are disposed in parallel in the lateral direction of the housing 110, the first connecting portion 142b and the second connecting portion 142c may be disposed in parallel above and below the hinge shaft portion 142 a.

On the other hand, a locking projection 142d may be provided on at least one of the first and second connecting

portions

142b and 142 c. The locking protrusion 142d is formed to protrude toward a space between the first connection part 142b and the second connection part 142c, and is formed to be engaged with the hooking protrusion 116c when the movable hinge part 142 slides.

In the present embodiment, the locking projection 142d is shown formed to protrude at the first connecting portion 142 b.

The present invention is not limited thereto. As an example of the variation, the locking projection 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 142 c.

In a state where the actuator 140 is located at the second position ii, the locking projection 142d is located forward of the hooking projection 116 c.

In this state, when the actuator 140 is slid toward the third position iii by an external force, the locking projection 142d passes over the hooking projection 116c by the external force. At this time, the first and second extending

portions

116a, 116b or the first and second connecting

portions

142b, 142c are elastically deformed.

In the state where the actuator 140 is located at the third position iii, the locking projection 142d is located behind the hooking projection 116c, i.e., in the groove 116.

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

Fig. 13 is a schematic view showing a slipping process of the actuator 140 from the bottom of the portion D shown in (b) of fig. 8, and fig. 14 is a schematic view taken along a line E-E' shown in fig. 13 to show the slipping process of the actuator 140.

Referring to fig. 13 and 14, wire insertion guides 143a are provided on both sides of the insertion portion 143. The wire insertion guide 143a is formed to protrude from the bottom of the insertion portion 143, and is inserted into the groove 1b formed on both sides of the wire 1 in a state where the actuator 140 is disposed to cover the wire 1 (a state located between the second position ii and the third position iii).

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

When 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 within the groove 1b of the electric wire 1.

When the actuator 140 is slid from the second position ii toward the third position iii in a case where the electric wire 1 is not completely inserted into the housing 113, the electric wire insertion guide 143a is formed to engage with the groove 1b of the electric wire 1 to press the electric wire 1 toward the housing 113. That is, when the actuator 140 slips, the electric wire insertion guide 143a pulls the electric 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 stably made.

In a state where the actuator 140 is located 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 1 b. At this time, the wire insertion guide 143a no longer presses the electric wire 1.

The wire attachment 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 disposed 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 locking projection 142d is located inside the insertion groove 116, and the hooking projection 116c is located in front of the locking projection 142 d. Therefore, if an external force of a predetermined magnitude or more is not applied, the locking projection 142d is engaged with the hooking projection 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, there is a possibility that the electric wire 1 may be pulled unexpectedly due to an error of an assembler or the like. 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 above configuration, the connection stability between the electric wire 1 and the electric connector 100 can be secured.
