Referring to fig. 1 to 4, the electrical connector assembly includes a wire assembly 10 and an electrical connector 100 fastened to the wire assembly 10 moved in a top-down manner (a manner of moving from top to bottom).
The electric wire assembly 10 includes electric wires 11 and a cover member 12.
The electric wire 11 is formed in a flat form having a thin thickness and a predetermined width, and has flexibility and bendability. A connection circuit is formed inside the electric wire 11, and a terminal portion 11a connected to the connection circuit is exposed to the outside at an end of the electric wire 11. In the present embodiment, the terminal portion 11a is located at the lower end portion of the electric wire 11.
The wire 11 corresponds to a soft Flexible Flat wire (FFC), a Flexible Printed Circuit (FPC), or the like.
The cover member 12 is formed to extend long in one direction and is arranged to cover the upper end of the electric wire 11. The cover member 12 may be attached to the upper end portion of the electric wire 11 by an adhesive. In the present embodiment, the cover member 12 is disposed so as to overlap the terminal portion 11a located at the lower end portion of the electric wire 11.

A front catching portion 12c may be formed on the front side of the cover member 12. The front locking portion 12c is formed to be engageable with a front lock unit 140 described later.
The front catching portion 12c may be formed in various forms according to the form of the front locking unit 140. For example, when the front lock unit 140 includes the engagement hole 142a, the front locking portion 12c may be formed in a convex shape that can be inserted into the engagement hole 142 a. Alternatively, as another example, when the front locking unit 140 includes a hook projection, the front locking portion 12c may be formed in a recessed shape or the like that can engage with the hook projection.
In the present embodiment, the front locking portion 12c is formed to protrude in a convex shape, and a plurality of front locking portions are provided and arranged at predetermined intervals in the longitudinal direction of the lid member 12.
The electrical connector 100 is configured to electrically connect the circuit board 20 and the electric wire 11 to constitute an electrical circuit. Specifically, the electrical connector 100 is mounted on the circuit board 20, and when the wire assembly 10 is connected, electrical contact is formed between a terminal portion 11a formed at an end of the wire 11 and a contact portion 122a of the terminal 120.
For reference, the circuit board 20 to which the electrical connector 100 is mounted includes not only the circuit board 20 of a rigid material but also a flexible circuit board of a flexible material.

As a modified example, the front lock unit 140 may further include a mounting portion extending from the mounting portion 141 and mounted on the circuit board 20.
The plurality of locking portions 142 may be provided and arranged at a predetermined interval in the longitudinal direction of the front fixing portion 114.
Cut portions 144 may be formed at both sides of the locking portion 142 so that the locking portion 142 can be elastically deformed in a state where the mounting portion 141 is fixed to the front fixing portion 114.
The locking portion 142 is formed to extend from the mounting portion 141 in a bent state and to be elastically deformable inward under pressure. In the present embodiment, the locking portion 142 is shown in a form extending downward and then curved and extending upward along the surface defining the recessed portion 114c, and is configured to be elastically deformable inward of the recessed portion 114 c.
The lock portion 142 is formed to be engageable with the front catching portion 12c by the elastic deformation. In the present embodiment, the locking portion 142 is formed with an engaging hole 142a into which the front engaging portion 12c formed to protrude in a convex shape can be inserted. The engaging hole 142a may be formed in a portion extending upward.
The locking portion 142 may further include an inclined portion 143 bent at a portion formed to extend to the upper side and extending to the inside of the recessed portion 114 c. When the wire assembly 10 is mounted so as to cover the wire mounting portion 112, the inclined portion 143 is formed to guide the front catching portion 12c formed to protrude in a convex form downward toward the catching hole 142 a.
Hereinafter, a process of fastening the wire assembly 10 to the electrical connector 100 will be described.
Fig. 7 is a schematic view of a process of fastening the wire assembly 10 to the electrical connector 100, taken along the line a-a 'of fig. 2, and fig. 8 is a schematic view of a process of fastening the wire assembly 10 to the electrical connector 100, taken along the line B-B' of fig. 2.
Referring to fig. 7 and 8, the wire assembly 10 is fastened to the electrical connector 100 by moving in a top-down manner to cover the wire mounting portion 112. At this time, the terminal portion 11a of the electric wire 11 and the turn-on portion 122a of the terminal 120 are disposed to face each other, gradually approaching by the movement.
When the cover member 12 is pressed downward in a state where the wire assembly 10 is arranged to cover the wire attachment portion 112, the side catching portion 12a and the front catching portion 12c of the cover member 12 are fixed to the side locking unit 130 and the front locking unit 140 of the electrical connector 100, respectively.
Specifically, the locking portion 132 of the side locking unit 130 is pressed by the side catching portion 12a and elastically deformed toward the inside of the partitioned space 113 c. Thereafter, when the cover member 12 moves further downward beyond the locking portion 132, the locking portion 132 is elastically restored and disposed to cover a part of the cover member 12.
At this time, the side engaging portion 12a formed to protrude in a convex shape in the lid member 12 is inserted into the engaging hole 132a formed in the locking portion 132.
Similarly, the lock portion 142 of the front lock unit 140 is pressed by the front catching portion 12c and elastically deformed toward the inside of the recessed portion 114 c. Thereafter, when the cover member 12 moves further downward beyond the locking portion 142, the locking portion 142 is elastically restored and arranged to cover a part of the cover member 12.
At this time, the front engaging portion 12c formed to protrude in a convex shape in the lid member 12 is inserted into the engaging hole 142a formed in the locking portion 142.
In this manner, the cover member 12 is fixed by the side locking unit 130 and the front locking unit 140 in a state arranged to cover the electric wire mounting part 112, and is held by the fixation in a state in which the terminal part 11a of the electric wire 11 and the turn-on part 122a of the terminal 120 exposed to the electric wire mounting part 112 are in contact with each other.
For more stable contact between the terminal portion 11a and the contact portion 122a, an insertion hole 116 or an insertion groove into which the leg portion 12b of the cover member 12 is inserted is formed between the electric wire mounting portion 112 and the side locking unit 130. That is, in a state where the electric wire assembly 10 is fastened to the electric connector 100, the leg portion 12b of the cover member 12 is formed to be inserted into the insertion hole 116 or the insertion groove between the electric wire mounting portion 112 and the side locking unit 130. According to the structure, the lateral movement of the wire assembly 10 is prevented. Therefore, the contact reliability between the terminal portion 11a of the electric wire 11 and the contact portion 122a of the terminal 120 can be ensured.
Hereinafter, a process of separating the wire assembly 10 from the electrical connector 100 will be described.
Fig. 9 is a schematic view for explaining a method of separating the wire assembly 10 shown in fig. 1 from the electrical connector 100.
Referring to fig. 9, when the locking portion 132 of the side locking unit 130 is pressed to be elastically deformed inward of the partitioned space 113c in a state where the wire assembly 10 is attached to the electrical connector 100, the locking of the right and left sides of the cover member 12 is released. That is, the locking portion 132 located above the side locking portion 12a moves in the lateral direction, and the lid member 12 can be lifted upward.
For reference, the elastic deformation of the locking portion 132 can be easily formed by the pressing operation of the push button 132 b. In this case, a dedicated jig capable of elastically deforming the locking portions 132 provided on both the left and right sides of the electrical connector 100 at a time may be used.
In a state where the locking of the right and left sides of the cover member 12 is released, if the cord set 10 is tilted up, the right and left sides of the cover member 12 are separated toward the upper side of the locking portion 132, and thus the front side of the cover member 12 can also be separated rearward from the locking portion 142.
As described above, the side locking unit 130 engaging the side locking portion 12a of the cover member 12 is formed to be elastically deformable outward by a pressing operation, and the wire assembly 10 can be easily separated from the electrical connector 100 by pressing the side locking unit 130 outward and then lifting the cover member 12.
Hereinafter, variations of the electrical connector assembly will be described.
Fig. 10 is a perspective view illustrating an electrical connector assembly according to another embodiment of the present invention, and fig. 11 is a schematic view illustrating a process of fastening the electrical wire assembly 10 to the electrical connector 200, taken along a section line C-C' of fig. 10.
Referring to fig. 10 and 11, the electrical connector assembly of the present embodiment has only a slight difference in the fastening structure of the front catching portion 12d and the front locking unit 240, compared to the electrical connector assembly of the previous embodiment.
For reference, the foregoing cross-sectional structure shown in fig. 8 is also equally applicable in the present embodiment. Therefore, the description of this is replaced with the description of fig. 8.
The lock portion 242 of the front lock unit 240 includes a hooking protrusion 242a, and the front locking portion 12d of the cover member 12 is formed in a recessed shape capable of engaging with the hooking protrusion 242 a. In the present embodiment, the front catching portion 12d is shown to be formed extending in the longitudinal direction of the lid member 12.
The plurality of locking portions 242 may be provided and arranged at a predetermined interval in the longitudinal direction of the front fixing portion 214.
Cut portions 244 may be formed at both sides of the locking portion 242 so that the locking portion 242 can be elastically deformed in a state where the mounting portion 241 is fixed to the front fixing portion 214.
A recessed portion 214c is formed at the front fixing portion 214 to which the front locking unit 240 is attached, the recessed portion 214c forming a space so that the locking portion 242 can be elastically deformed inward by pressurization. In the present embodiment, it is illustrated that the recessed portion 214c is formed to be inclined inward and downward in front of the front fixing portion 214.
The locking portion 242 is vertically bent downward on the upper surface of the mounting portion 241. When an external force is applied, the vertically bent portion is elastically deformed toward the recessed portion 214 c.
A hooking protrusion 242a is protrudingly formed at the vertically bent portion. The hooking protrusion 242a may be formed by undulation.
Referring to fig. 11, in a state where the wire assembly 10 is disposed so as to cover the wire attachment portion 212, when the cover member 12 is pressed downward, the locking portion 242 of the front locking unit 240 is pressed by the front catching portion 12d and elastically deformed toward the recessed portion 214 c. Thereafter, when the cover member 12 moves further downward beyond the hooking protrusion 242a, the locking portion 242 is elastically restored, and the hooking protrusion 242a is disposed to cover the front catching portion 12d, thereby locking the wire assembly 10.
