Further, although the assembly process is simple, the pulling out of the flexible circuit 2 is prevented by the locking piece 213, and the pulling out of the flexible circuit 2 is prevented by the retainer 220. Therefore, the flexible circuit 2 and the second connector 200 There is an advantage that the coupling of is performed firmly.

  Hereinafter, the coupling structure of the first connector 100 and the second connector 200 will be specifically described. 11 is a cross-sectional view taken along line A-A of FIG.

  Referring to FIGS. 1 to 3, the wafer 110 is provided with a lock hole 114 for coupling with the housing 210. The lock hole 114 is formed on one side of the wafer 110 and configured to be coupled to the lock protrusion 230 ′ of the housing 210.

  Referring to FIG. 11 together with FIGS. 1 to 3, the lock hole 114 is engaged with a lock protrusion 230 ′ of an elastic arm 230 described later when the second connector 200 is accommodated in the housing accommodation portion 111. It may be configured to be combined. That is, the second connector 200 can be firmly fixed to the first connector 100 by the lock hole 114 and the lock protrusion 230 ′.

  The housing 210 is formed with an elastic arm 230 elastically deformable at a position corresponding to the lock hole 114. The elastic arm 230 may be in the form of a cantilever that can be elastically deformed inward.

  A lock protrusion 230 ′ may be provided on one surface of the elastic arm 230 opposite to the lock hole 114 of the housing 210. When the housing 210 is inserted into the housing accommodating portion 111, the elastic arm 230 is elastically deformed inward by the wafer 110, and the lock projection 230 ′ is locked in the lock hole 114.

  One end of the elastic arm 230 is provided with a pressing portion 230 ′ ′ capable of pressing. When the pressing portion 230 ′ ′ is operated (in the same figure, the pressing portion 230 ′ ′ is pressed inward), the elastic arm 230 inclines inward and the lock protrusion 230 ′ is separated from the lock hole 114, and the second connector It is possible to separate 200 from the first connector 100. Therefore, there is an advantage that the second connector 200 can be easily separated from the first connector 100.

  Referring to FIGS. 4, 5 and 7, the housing 210 may be formed with a locking rib 216 for limiting the outward movement of the elastic arm 230. The locking rib 216 may be formed to cover at least a portion of the elastic arm 230. In the same figure, it shows that the part which protruded to the right and left of elastic arm 230 is formed, and it is formed so that the part which locking rib 216 protruded may be covered.

  On the other hand, as shown in FIG. 11, the terminal 120 includes a base portion 121, a first connection portion 122, and a second connection portion 123, for electrical connection between the circuit board 1 and the flexible circuit 2.

  The base portion 121 is formed long in the front-rear direction of the wafer 110 and is provided at a terminal attachment portion of the wafer 110. The base portion 121 is provided with a lower contact portion 121 ′ that protrudes from the lower portion of the wafer 110 and contacts the upper surface of the circuit board 1.

  The first connection portion 122 extends from one side of the base portion 121, and is configured to press at least one side surface of the terminal portion 2b of the flexible circuit 2 when the flexible circuit 2 is inserted into the flexible circuit housing portion 211. . Specifically, the first connection portion 122 may be formed so as to be bent at at least one point to elastically press the terminal portion 2b. Referring to the figure, the first connection portion 122 is disposed to face the opening 212, and one end of the first connection portion 122 passes through the opening 212 to press one side of the terminal portion 2b. It may be configured.

  The second connection portion 123 may extend from the other side of the base portion 121 and may be formed side by side with the first connection portion 122. That is, the second connection portion 123 may be arranged to cover the other surface of the housing 210 which is the opposite surface of the surface on which the opening 212 is formed. Thus, the second connection portion 123 supports the other surface of the housing 210 inserted into the flexible circuit housing portion 211.

  In the same figure, the terminal 120 includes a first connection portion 122 and a second connection portion 123 which are disposed at predetermined intervals in the left-right direction of the housing 210, and the housing 210 is formed by the first connection portion 122 and the second connection portion 123. Indicates that the lower end of the is configured to be enclosed.

  On the other hand, according to the above-described coupling structure, the process of assembling the flexible circuit 2 is simple, and the electrical connector assembly 10 forming a strong coupling between the first connector 100 and the second connector 200 can be realized.

  Specifically, when housing 210 is coupled to wafer 110, terminal 2b of flexible circuit 2 inserted in housing 210 is exposed from opening 212, and terminal 120 of wafer 110 is connected to terminal 2b. Therefore, the electrical connection between the first connector 100 and the second connector 200 is smoothly performed.

  In addition, since one end of the housing 210 is accommodated in the housing accommodation portion 111 of the wafer 110 and the lock projection 230 'of the housing 210 is locked to the lock hole 114 of the wafer 110, the first connector 100 and the second connector 200 The conclusion of the

  Furthermore, the flexible circuit 2 is accommodated in the flexible circuit accommodating portion 211 and fixed by the retainer 220, whereby the assembly of the flexible circuit 2 and the second connector 200 is completed, and the housing 210 is accommodated in the housing accommodating portion 111. The assembly of the first connector 100 and the second connector 200 is completed by fastening to the wafer 110 by the lock hole 114 and the lock protrusion 230 ′.

  According to such an assembly structure, assembly of the flexible circuit 2 and the second connector 200 can be reduced since the assembly of the flexible circuit 2 and the second connector 200 can be reduced. Since the assembly with the two connectors 200 is easy, the time and effort required for the manufacturing process can be reduced.

  FIGS. 12A and 12B are enlarged views of a structure for protecting the flexible circuit 2 in the process of coupling the second connector 200 to the first connector 100. FIG. Specifically, (a) of FIG. 12 shows a state in which the second connector 200 is being inserted into the first connector 100, and (b) of FIG. 12 shows that the second connector 200 is the first connector 100. Show a completely fastened state.

  As shown in the figure, the housing 210 is formed thicker than the first portion 210a at the end of the terminal portion 2b and at the rear (upper side in the figure) of the first portion 210a than in the first portion 210a. And a second portion 210b. In the figure, the first portion 210 a forms the lower end of the housing 210.

  The opening 212 is formed across one side of the first portion 210a and one side of the second portion 210b. That is, the terminal portion 2b of the flexible circuit 2 is exposed from the opening 212 formed across the first portion 210a and the second portion 210b.

  The terminal 120 includes a first connection portion 122 and a second connection portion 123 which protrude to face each other in the housing accommodation portion 111. The distance between the first connection portion 122 and the second connection portion 123 of the terminal 120 is wider than the thickness of the first portion 210a and smaller than the thickness of the second portion 210b.

  Therefore, in the state shown in FIG. 12A, the first portion 210a is easily inserted into the space between the first connection portion 122 and the second connection portion 123 without interference or not much interference. . On the other hand, in the state shown in (b) of FIG. 12, the second portion 210b presses the first connection portion 122 and the second connection portion 123 in the direction away from each other, compared with the state of (a) of FIG. And are inserted with more interference.

  The terminal 120 further includes a base portion 121 mounted on the circuit board 1 to connect the first connection portion 122 and the second connection portion 123. Structurally, the end of the housing 210 is inserted into the space defined by the first connection portion 122, the base portion 121 and the second connection portion 123.

  The base portion 121 is disposed in parallel to the circuit board 1.

  The second connection portion 123 protrudes vertically from the base portion 121. The second connection portion 123 is disposed perpendicularly to the circuit board 1.

  The first connection portion 122 protrudes in an arch shape slightly bent from the base portion 121 toward the second connection portion 123. Therefore, the distance between the first connection portion 122 and the second connection portion 123 is narrower at the end portion than at the base portion 121 side. Such a shape allows the first connection portion 122 to be elastically deformed. That is, due to the elastic deformation of the first connection portion 122, the distance between the first connection portion 122 and the second connection portion 123 is variable.

  On the other hand, when a large load is applied to the terminal portion 2b, the terminal portion 2b is damaged, but when a large load is applied at the beginning of the insertion process, the terminal portion 2b may be scratched, or if severe, the terminal portion 2b may be damaged There is also something to do. However, when the load is applied to a position where contact is substantially achieved (that is, the second portion 210b) separated from the end of the terminal portion 2b as in the present invention, such a problem may occur. Can be solved.

  Specifically, as shown in FIG. 12A, in the process in which the first portion 210a enters between the first connection portion 122 and the second connection portion 123, the first portion 210a corresponds to the first portion 210a of the opening 212. If the terminal portion 2b exposed from the portion where it is exposed does not touch the first connection portion 122, or if the terminal portion 2b contacts the first connection portion 122, no load is applied to the extent that the terminal portion 2b is damaged.

  Thereafter, as shown in (b) of FIG. 12, when the second portion 210b enters between the first connection portion 122 and the second connection portion 123, it is exposed from the portion of the opening 212 corresponding to the second portion 210b. The terminal portion 2 b contacts the first connection portion 122.

  At this time, the second portion 210b is supported by the second connection portion 123, the first connection portion 122 is elastically pressed outward, and the terminal portion 2b is pressed by a restoring force. Further, as described above, since the first connection portion 122 is formed in an arch shape, the terminal portion 2 b exposed from the portion corresponding to the first portion 210 a in the opening 212 does not contact the first connection portion 122.

  Meanwhile, the housing 210 may further include an inclined portion 210c connecting the first portion 210a and the second portion 210b in an inclined manner. In this case, in the process of inserting the housing 210, the inclined portion 210c comes into sliding contact with the second connection portion 123, and guides the second connection portion 123 to smoothly contact the second portion 210b thereafter. .

  13 to 16 show modifications of the present invention. Specifically, the second connector 400 is disposed to cover the circuit board 1 and is horizontally coupled to the first connector 300. Therefore, the structure in which the distance between the circuit board 1 and the second connector 400 is narrow can be realized. Hereinafter, the structure will be described more specifically.

  FIG. 13 is a perspective view showing a modification of the electrical connector assembly 20. As shown in FIG. FIG. 14 is an exploded perspective view showing the main configuration shown in FIG. 13 separately. FIG. 15 is a cross-sectional view taken along line C-C of FIG. FIGS. 16A and 16B are enlarged views of a structure for protecting the flexible circuit 2 in the process of connecting the second connector 400 to the first connector 300. FIG.

  Similar to the electrical connector assembly 10 according to an embodiment of the present invention, the electrical connector assembly 20 of the present variation includes a first connector 300 and a second connector 400. In addition, the first connector 300 may include the wafer 310, the terminal 320, and the like, and the second connector 400 may include the housing 410, the retainer 420, and the like. These are the same as in the above embodiment.

  Hereinafter, the configuration for coupling (or assembling) the first connector 300 and the second connector 400 will be described with reference to the same figure.

  The housing accommodating portion 311 extends in the horizontal direction (from the front to the rear), and has a recessed concave shape.

  The flexible circuit housing portion 411 extends in the horizontal direction and has a concave shape that is recessed.

  On the other hand, the terminal 320 is attached to the side surface of the wafer 310 and installed so that its end projects into the housing accommodation portion 311 when inserted into the inside.

  Specifically, the base portion 321 extends in the height direction of the wafer 310 and is provided at the terminal attachment portion of the wafer 310. The base portion 321 protrudes from the side portion of the wafer 310 and is provided with a lower contact portion 321 ′ at one end that contacts the upper surface of the circuit board 1.

  The first connection portion 322 extends from one side of the base portion 321 in a direction parallel to the circuit board 1, and at least one side surface of the terminal portion 2 b of the flexible circuit 2 when the flexible circuit 2 is inserted into the flexible circuit housing 411. Configured to pressurize.

  The second connection portion 323 may extend from the other side of the base portion 321 and be formed side by side with the first connection portion 322.

  That is, this modification is different from the above embodiment in that the direction in which the second connector 400 is coupled to the first connector 300 is not vertical but horizontal. Therefore, the flexible circuit 2 is horizontally inserted in the flexible circuit accommodating portion 411 of the housing 410 and fixed by the retainer 420, and the housing 410 is horizontally inserted in the housing accommodating portion 311 and fastened to the wafer 310. The assembly process of the electrical connector assembly 20 is completed.

  According to the above structure, the second connector 400 can be attached to the first connector 300 by the horizontal coupling method adopted for the electrical connector assembly 20 even if the assembly space is not secured on the upper portion of the circuit board 1. There is an advantage that it is advantageous to secure work space.

  On the other hand, the structure of the electrical connector assembly 20 in the state where the first connector 300 and the second connector 400 are coupled is as follows.

  Unlike the second connector 200 of the electrical connector assembly 10 according to the embodiment, the second connector 400 is disposed adjacent to the circuit board 1. That is, the second connector 400 is arranged to cover at least a part of the circuit board 1.

  According to the above-described structure, in the state where the second connector 400 is coupled to the first connector 300, the distance from the circuit board 1 to the top of the electrical connector assembly 20 is shortened. Therefore, there is an advantage that the space utilization inside the device is improved, and the device with reduced thickness and the like can be realized.

  FIGS. 16A and 16B are enlarged views of a structure for protecting the flexible circuit 2 in the process of connecting the second connector 400 to the first connector 300. FIG. Specifically, FIG. 16A shows a state in which the second connector 400 is being inserted into the first connector 300, and FIG. 16B shows the second connector 400 being the first connector 300. Show a completely fastened state.

  As shown in the figure, the housing 410 is formed thicker than the first portion 410a at the end of the terminal portion 2b and at the rear (right side in the figure) of the first portion 410a than the first portion 410a. And a second portion 410b. In the figure, the first portion 410 a forms the front end of the housing 410.

  The opening 412 is formed across one side of the first portion 410a and one side of the second portion 410b. That is, the terminal portion 2b of the flexible circuit 2 is exposed from the opening 412 formed over the first portion 410a and the second portion 410b.

  The terminal 320 includes a first connection portion 322 and a second connection portion 323 which are opposed to each other in the housing accommodation portion 311. The distance between the first connection portion 322 and the second connection portion 323 of the terminal 320 is wider than the thickness of the first portion 410a and smaller than the thickness of the second portion 410b.

  Therefore, in the state shown in FIG. 16A, the first portion 410a is easily inserted into the space between the first connection portion 322 and the second connection portion 323 without interference or not much interference. . On the other hand, in the state shown in (b) of FIG. 16, the second portion 410b pressurizes the first connection portion 322 and the second connection portion 323 in a direction away from each other, compared to the state of (a) of FIG. And are inserted with more interference.

  The terminal 320 further includes a base portion 321 mounted on the circuit board 1 to connect the first connection portion 322 and the second connection portion 323. Structurally, the end of the housing 410 is inserted into the space defined by the first connection portion 322, the base portion 321 and the second connection portion 323.

  The base portion 321 is disposed perpendicularly to the circuit board 1.

  The second connection portion 323 is vertically protruded from the base portion 321. The second connection portion 323 is disposed in parallel with the circuit board 1.

  The first connection portion 322 protrudes in an arch shape slightly bent from the base portion 321 toward the second connection portion 323. Therefore, the distance between the first connection portion 322 and the second connection portion 323 is narrower at the end portion than at the base portion 321 side. Such a shape allows the first connection portion 322 to be elastically deformed. That is, due to the elastic deformation of the first connection portion 322, the distance between the first connection portion 322 and the second connection portion 323 is variable.

  On the other hand, when a large load is applied to the terminal portion 2b, the terminal portion 2b is damaged, but when a large load is applied at the beginning of the insertion process, the terminal portion 2b may be scratched, or in a severe case, the terminal portion 2b may be damaged. There is also something to do. However, when the load is applied to a position where contact is substantially achieved (that is, the second portion 410b) separated from the end of the terminal portion 2b as in the present invention, such a problem may occur. Can be solved.

  Specifically, as shown in FIG. 16A, in the process in which the first portion 410a enters between the first connection portion 322 and the second connection portion 323, it corresponds to the first portion 410a of the opening 412. If the terminal portion 2b exposed from the portion where it is exposed does not touch the first connection portion 322, or if the terminal portion 2b contacts the first connection portion 322, no load is applied to the extent that the terminal portion 2b is damaged.

  Thereafter, as shown in (b) of FIG. 16, when the second portion 410b enters between the first connection portion 322 and the second connection portion 323, it is exposed from the portion corresponding to the second portion 410b of the opening portion 412. The terminal portion 2 b contacts the first connection portion 322.

  At this time, the second portion 410b is supported by the second connection portion 323, the first connection portion 322 is elastically pressed outward, and the terminal portion 2b is pressed by a restoring force. Further, as described above, since the first connection portion 322 is formed in an arch shape, the terminal portion 2 b exposed from the portion corresponding to the first portion 410 a of the opening portion 412 does not contact the first connection portion 322.

  Meanwhile, the housing 410 may further include an inclined portion 410 c connecting the first portion 410 a and the second portion 410 b in an inclined manner. In this case, in the process of inserting the housing 410, the inclined portion 410c comes into sliding contact with the second connection portion 323, and guides the second connection portion 323 so as to smoothly contact the second portion 410b thereafter. .

  Meanwhile, the electrical connector assembly of the present invention can be applied to display equipment. In addition, a television is mentioned as an example of a display apparatus.
